These photographs document the Hoffmann-Hayman Coffee Company plant in San Antonio — the building where the beans were roasted, the tins were filled, and the Crystalvac jars were packed — along with letterhead, loading-dock iron, and cross-references that tie the place to the product. The image grid follows the ordered sequence: in _data/galleries/factory/order.yml; this outline groups the same material by theme so you can browse by topic.

the face of the cap carries a stamped pattern of short radial tick marks emanating from a central center-punch dimple and three legible stamped letters arranged around the perimeter reading 'M' near the top, an 'A' (rendered as a triangular form, the crossbar faint) on the right, and a 'G' (a curled half-circle character) at the lower-left — most legibly read as 'G — M — A', a surveyor's initials, firm code, or agency stamp whose specific attribution is not yet identified; the marker sits on Delaware Street at the same Delaware-and-Southern-Pacific-tracks address recorded in the 1932 San Antonio Sunday Light feature on the new Hoffmann-Hayman plant ([documented in the Collection gallery](/sunday-light-july-1932-factory-article-reprint/)), a 21st-century property/survey artifact at the same street boundary the 1932 paper named when the factory was being built Steep downward-looking photograph across a weathered pale-grey sidewalk slab on **Delaware Street beside the Hoffmann-Hayman factory entrance gate** — coarse drag **horizontal striations** across the floated concrete lift, lower edge bordering a grassy verge scattered with browned leaves where small yellow composite wildflowers poke through (**17 December 2014**, **iPhone 5**) — inscribed into the hardened surface toward the slab **margin** (wet-concrete handwriting from when the pavement was poured or struck) reads **ADOLPH** then a spaced gap followed by **M.** capped with **serif-ish block capitals**, the letter grooves sunk and edged with grime so the name reads charcoal-dark against smoother paste — read here as **Adolph Menger**, of the **Menger–Hoffmann** family lineage at the center of Hoffmann-Hayman and this plant (see **[People]({{ site.baseurl }}/people/)**);

overall reading as auxiliary **jeweller's / office strongbox** securing cash or documents beside heavier vault-rated equipment Close-up of one of the wooden interior drawers of the large floor safe inside the Hoffmann-Hayman factory vault, photographed 10 February 2015 (iPhone 5) — dark reddish finish with decorative gold-line banding, round brass keyhole at center-top, and an aged tan paper label typewritten with two lines reading 'MRS. C. B. MENGER' and 'INSURANCE' Exposed expanded-diamond metal lath underlying the plaster wall treatment in the first-floor bathroom at the Hoffmann-Hayman factory, immediately adjacent to the vault — with patches of plaster fallen away to reveal the lath and the red brick wall behind it Looking up at a first-floor ceiling corner at the Hoffmann-Hayman factory, where a rough board-formed reinforced-concrete beam meets its column and the slab above — the horizontal grain of the 1930s formwork boards is pressed into the beam's vertical face, a galvanized water line runs along the beam at left, and steel electrical conduit is strung along the beam soffit; exposed aggregate is visible where a shoulder of concrete has spalled away at the beam's top edge Standing at the north entry to the freight elevator on the first floor of the Hoffmann-Hayman factory and looking up through the board-formed concrete shaft header into the second floor above — concrete block (CMU) shaft walls, vertical steel elevator guide rails, and electrical conduit run up to the opening, with wood framing and scaffolding visible through the bright daylight at the top Low-light close-up on the **interior north wall** of the **first floor** at the Hoffmann-Hayman factory — a single masonry stretcher bearing the raised embossed legend **STAR BRICK** in serif capitals (the manufacturer's name-mark block), olive-grey porous clay with a faint horizontal frog line bisecting the lettering, seated in granular buff-grey mortar joints; the wythe sits below a coarse dark relieving course at the top edge of frame and drops into badly spalled and missing mortar toward the bottom, revealing rough subsurface masonry and cavities in deep shadow — readable **maker lettering** tying the site's summary language about **star-stamped San Antonio street bricks** to **in situ masonry** inside the factory's north **first-floor** interior (**interior north wall** per site documentation — **this gallery** places the frame immediately **after** the **[north-end freight elevator look-up](/assets/images/gallery/factory-downstairs-elevator-shaft.jpg)** listing); photographed **4 December 2014** (**iPhone 5**) with grain characteristic of handheld low-light capture Freight Elevator Motor Close-up mechanical detail on the **second floor machine level** of the Hoffmann-Hayman factory's **interior freight elevator** (**chain-and-sprocket hoisting**, not the exterior track-side lift documented elsewhere in **this gallery**) — **steel roller chain** drapes vertically into frame and **wraps a cast sprocket** whose teeth visibly **seat between** each link paddle, coaxial steel **journal shaft** passing through greased pillow-housing flange **bolted to a rounded cast bracket** anchored to whitewashed **plaster** / board wall (**left**) with rusty through-bolt heads; cylindrical **oiler / grease nipple boss** perched atop the gearbox half — packing **thick old** black fibrous grease and reddish iron oxide; reddish **expanded-metal or wire-grid veil** behind (**shaft infill**) and upright **dimension-lumber trim** (**right**) with warm grain under dim interior light — **documentation** companion to **[Freight Elevator Motor](/assets/images/gallery/factory-elevator-motor.jpg)** and **[first-floor north-entry shaft look-up](/assets/images/gallery/factory-downstairs-elevator-shaft.jpg)** on **this building's interior freight elevator**; **7 October 2015**, **iPhone 5**, handheld **available-light** (visible **ISO noise**, slightly soft chain) Tight close-up of the UP/DOWN pushbutton station controlling the **smaller second lift** at the Hoffmann-Hayman factory — a separate, smaller mechanism from the building's main interior freight elevator, fitted with an **exterior access door opening to the track side** so loads can be moved directly between the plant and the Southern Pacific siding running along the west flank — a grey-painted cast-iron pushbutton enclosure made by **Square D Company, Milwaukee, Wis., U.S.A.**, brass nameplate stamped 'CLASS 9001 / TYPE B-10 / MAX. V. 600 AC/DC / 218278 GG', two heavy round push buttons each cast with the legends 'UP' (top) and 'DOWN' (bottom), the button faces worn dark and oily from decades of use, mounted by four corner machine screws to a riveted steel angle-iron post behind a heavy diamond chain-link guard mesh — same physical Square D station documented in the wider track-side-lift cage view (matching nameplate and serial 218278 GG) Heavily oxidized **General Electric 'Control'-branded roller-lever travel limit switch** mounted on the riveted steel structural frame of the same smaller second lift at the Hoffmann-Hayman factory — the smaller mechanism (distinct from the main interior freight elevator) fitted with the **exterior access door** opening to the **track side** of the building onto the Southern Pacific siding — photographed on 5 January 2025; a small black-painted cast-metal enclosure carries a brass cover plate embossed in raised lettering with 'GENERAL ELECTRIC' across the top in a banner, a circular red-and-white **GE monogram badge** at center, and 'Control' in flowing italic script below the monogram (the standard pre-1960s GE 'Control' nameplate styling); the cover is held on by four slotted machine screws (one at each corner) with two further visible screws on the body, and out of the top of the case projects a steel **roller-lever actuator arm** pivoting on a hex-cap screw with a brass actuating roller at its outer end (positioned to be physically tripped by an end-of-travel cam or lug on the moving lift platform when the lift reaches the top or bottom of its travel, breaking the contacts inside the case and cutting power to the lift motor — a standard travel/end-of-travel limit switch); the bottom of the case is fitted with a threaded conduit hub feeding a length of **white/grey-jacketed flexible BX-style armored power cable** that loops down past additional wire mesh visible at lower-right, and the whole assembly is bolted to a heavy structural steel angle/channel post that's part of the lift's frame, with weathered tongue-and-groove vertical wood siding visible through the gap on the right of the frame and bright sunlight breaking through behind — most likely from the **trackside exterior access door** itself standing open at the moment of the photograph Fire Hose Mfg The second of two W. D. Allen Mfg. Co. fire-hose stations documented on the second floor of the Hoffmann-Hayman factory — a cast-iron swing bracket bolted to a white-painted structural column, maker's plate reading 'W. D. ALLEN MFG. CO. — CHICAGO, NEW YORK — PATENTED AUG. 1924', with a threaded elbow feeding a galvanized standpipe running down beside the column and a red painted band on the adjacent column marking the fire-equipment station Cast-iron handwheel gas-line shutoff valve in the northwest corner of the second floor of the Hoffmann-Hayman factory, photographed on 5 January 2025 — a heavily oxidized vertical iron riser pipe runs floor-to-ceiling against the wall corner, and a horizontal valve body is clamped to the riser by a bolted bracket (two visible through-bolts gripping the riser) projecting a short horizontal stub out into the room and terminating in a polished brass/bronze hex union nut and a four-spoke cast-iron round handwheel painted rust-red, the union nut sitting between the valve body and the handwheel-side connection so the valve can be unscrewed for service; the assembly is a typical period plant-services branch shutoff sitting in the corner where two whitewashed plaster-over-masonry walls meet, both wall faces carrying a fine, regular horizontal ribbing/banding texture (consistent with either scored scratch-coat plaster or impressions of underlying lath showing through thin whitewash) with a patch of bare red-brick masonry exposed in the upper right corner where the whitewash has worn or fallen away — same kind of whitewashed-brick second-floor interior surface that surrounds the building's other upstairs plant-services hardware Upward-angled photograph on the **second floor** of the Hoffmann-Hayman factory — **gas piping** run **against the underside of the ceiling** (paired large **circular cast-iron gate-valve handwheels** bolted onto flanges on a horizontal galvanized or black iron header that Tee-branches upward to a capped vertical stub alongside elbows and screwed couplings); the metal carries decades of oxidation, flaky old paint residue, and plant grime typical of untouched upstairs mains; the upper field reads as rough dark plank or board ceiling soffit and the lateral wall backdrop shows corrugated or rib-pattern industrial cladding, with thin flexible cabling crossing behind mid-frame above a ribbed masonry or block-face lower wall — photographed **1 December 2014** (iPhone 5); **companions** elsewhere on second-floor plant services include the separately documented **[northwest-corner gas shutoff on a vertical riser](/assets/images/gallery/factory-upstairs-northwest-corner-gas-valve.jpg)** (5 January 2025), a physically different vantage on the upstairs gas installation **Second floor**, **plant-gas service zone** at the Hoffmann-Hayman factory (per site note: **on the walk** near documented **upstairs gas valves**) — tight frontal photograph of a **wall-mounted sheet-steel enclosure** (**motor starter**, **disconnect**, or **junction** cabinet) in **advanced corrosion**: **alligatoring off-white enamel** lifting in **broad curls** over **burnt-orange rust**; **small screwed nameplate** across the upper field reading **OLD ROASTER** in **machine lettering** (**sans-serif caps**), a plant id tying the box to retired **coffee-roast** equipment on a circuit already summarized on the **[first-floor Trumbull panel directory](/assets/images/gallery/breaker-panel-labels.jpg)** under **'1 ROASTER MOTOR'** / **'3 GAS-AIR FAN'**; **rigid conduit** nipple enters the **roof** of the box; **deeper lower rebate** or **pulled weldment** in the **fascia**; **oxidized door-pull / latch iron** at **camera-right**; backdrop **pale green-grey painted masonry** with a **dark unstopped opening** **right** of frame — **spatial companions** in **this gallery** include the **[ceiling gas handwheels](/assets/images/gallery/2014-12-01-factory-second-floor-ceiling-gas-valves-handwheels.jpg)** and **[northwest-corner riser shutoff](/assets/images/gallery/factory-upstairs-northwest-corner-gas-valve.jpg)** — **Instagram** media export **18022184360636032** Inside-of-door circuit directory of the older **Trumbull Electric Mfg.

The number of branch circuits per leg must not exceed one-tenth of the current rating of the 'main' breaker.', a horizontal rule, and 'WIRE ALL BREAKERS PER TYPICAL WIRING DIAGRAM'; the manufacturer's masthead at the bottom reads '**FEDERAL PACIFIC ELECTRIC COMPANY · NEWARK, NEW JERSEY**' (the mid-twentieth-century FPE breaker panel — a major American panel/breaker maker from roughly the late 1950s through the 1980s) above a small catalog/serial line beginning 'Y31…' and a printed safety paragraph headed 'WARNING:' about not replacing breakers with higher-rated ones; **handwritten in pencil** across the directory in capital block letters by plant staff are three labels on three separate odd-circuit lines on the left column — '**TEA MACHINE**' on the line for circuit 3, '**AIR COND.**' on the line for circuit 7, and '**SIFTER**' on the line for circuit 17 — the rest of the circuit slots (5, 9, 11, 13, 15, 19, 21, 23, and the entire even column 2–24) left unlabeled;

related **[Delaware-Street factory profile](/{{ site.baseurl }}/sunday-light-july-1932-factory-article-reprint/)** (**1932** *Sunday Light*, same footprint) Low-angle view looking up at the junction of a **red brick** wall and a **grey reinforced-concrete beam or slab edge** inside the second-floor **expansion room above the office** at the Hoffmann-Hayman factory, photographed **10 November 2016** (source iPhone 6s) — the brick in the lower field is relatively clean, with light mortar joints; the concrete soffit or beam above carries rough cast texture, board-form grain, and weathering; on the **vertical face of the concrete** directly over the brick, a **handwritten dark marker or pencil inscription in Spanish** reads **'12 de 1949 FEBRERO'** (12 February 1949), with a second smaller line **'21-52'** partly visible beneath; this **1949** mark on the structure predates the **cursive pencil** Spanish dates elsewhere in the same expansion space grouped in the 1950s (the **'Marzo' 1952–1954** sequence on the east wall, the **'FEBRERO 11 – 53'** joist, and the **'AGOSTO 8 – 56'** joist) and is consistent with a separate early construction note or roofer’s phase mark at the ceiling line, though the hand and exact intent are not yet tied to a single work crew Close-up, roughly top-down photograph of **one face of a reddish masonry brick** in **grey mortar** on an **interior wall of the second floor** at the Hoffmann-Hayman factory, documented **24 October 2014** (source **iPhone 5**) — the brick carries a **personal graffito** in dark ink or ballpoint: **'Henry + Rosa'** at center (with **'+'** joining the names), **'Aug 8, 1949'** filed in the upper right, and **'San Antonio, Texas'** centered below the names, all loosely enclosed inside a **dashed-line heart** outline drawn on the glazed brick face with a curved **arrow** running from lower-left toward the bottom of the heart; fine light **scratches** cross the brick face — a **six months later** doodle-on-the-wall **counterpoint** in English to the **February 1949 Spanish** tradesmen’s marks elsewhere in the same **upstairs expansion** chronology, but here reading as a **couple’s** hand rather than a crew date; joints to neighboring bricks visible at lower and right edges Close-up of the east interior wall of the second-floor expansion room above the office at the Hoffmann-Hayman factory, photographed on 1 February 2023 — scored plaster/render finished in white paint that imitates brick coursing (raised mortar-joint lines running horizontal and vertical across the surface), the paint delaminating and peeling extensively in irregular sheets and a large T-shaped spall at center-left revealing the warm red-brown substrate underneath; three cursive graphite-pencil inscriptions centered in the upper field, written in the same hand in Spanish — 'Marzo 5 - 1952', 'Marzo 25 - 1953', and 'Marzo 18 - 1954' — three mid-March dates one per year across three consecutive years, someone returning to this wall each March; additional red crayon / lumber-keel markings in the lower half including large peaked/triangular shapes on the right and partial red letterforms (an 'R' and the start of another character) at the bottom edge Upward view showing the junction between the pan-formed reinforced-concrete joist ceiling of the second-floor expansion room above the office at the Hoffmann-Hayman factory and what was originally a 1932 exterior masonry face of the plant (now an interior wall enclosed by the expansion), photographed on 1 February 2023 — in the upper two-thirds, parallel flat-sided concrete joists run across the frame with board-formwork grain and round knot-hole imprints pressed into their sides, and the bays between them carry the characteristic ribbed soffit pattern left by removable corrugated-steel pan forms; on the flat face of one central joist a cursive graphite-pencil inscription reads 'FEBRERO - 11 - 53' (February 11, 1953), a second pencil date by the same hand or cohort as the three 'Marzo' 1952–54 dates on the east wall of the room and the later 'Agosto 8 – 56' mark on the adjacent ceiling joist; below the ceiling, the top of the former exterior masonry face of the original 1932 plant meets the expansion soffit, its painted surface streaked with long vertical whitewash drip-runs from when the new interior ceiling above was painted, and a wooden jamb is visible at lower-right in what appears to be a post-expansion cut opening in the old exterior wall; a thin black signal cable runs horizontally below the inscribed joist A roughly oval, rounded-irregular **hole punched through the original 1932 exterior face of the plant** as it stands today inside the second-floor expansion room above the office at the Hoffmann-Hayman factory, photographed on 5 January 2025 — the wall in question being the **same exterior masonry face documented in the [adjacent ceiling-junction frame](/assets/images/gallery/factory-upstairs-ceiling-febrero-date.jpg)** with the 'FEBRERO 11 – 53' pencilled joist, now reading as an interior wall because the post-1932 second-floor expansion was built over and beside it; the camera-facing surface is a smooth grey **stucco / cement-render interior finish** with hairline shrinkage cracks tracing through the field and a faint **red crayon / lumber-keel scribble** in the upper right (matching in material and hand the same red crayon marks already documented on the [east wall of this room beside the 1952–54 'Marzo' pencil dates](/assets/images/gallery/factory-upstairs-east-wall-marzo-dates.jpg)); the broken edges of the hole expose the wall in cross-section, revealing what reads as a textbook **early-1930s fire-resistant industrial wall buildup** — a course of warm orange-clay **fired brick veneer** visible at the upper margin of the cut, behind it a stack of three to four characteristic curved/lobed cell profiles consistent with the broken interior webs of **hollow structural clay tile** (terra-cotta hollow tile blocks) used as backup masonry behind the brick veneer, and the smooth grey stucco render skinning the interior face — the kind of brick-veneer-over-hollow-tile composition consistent with the *San Antonio Sunday Light*'s [July 1932 description of the new plant as 'fireproof reinforced-concrete' construction](/sunday-light-july-1932-factory-article-reprint/) (concrete frame plus fireproof masonry infill); through the hole the room beyond is visible — a clear gridded blue-and-silver field reading as one of the building's industrial windows with security mesh / wire-grid in front of it, daylight coming through, the same kind of caged-window run already documented on the [west flank from the rail siding at dusk in February 2019](/assets/images/gallery/factory-south-end-from-tracks-2019.jpg) Second-floor **post-1932 expansion inventory** bay at the Hoffmann-Hayman factory — **west interior wall** of the **first expansion** shell (per site note: loading / storage zone), photographed **24 November 2015** (**iPhone 5**) — straight-on view of **painted concrete-masonry-unit (CMU) blockwork** with **two parallel horizontal ragged punctures** roughly **one block course high** and **two cells apart on center**, a damage pattern consistent with **lift-truck / forklift fork tines** having been driven through the wythe — distinct from the **deliberate oval exploratory hole** through the **original 1932 exterior leaf** documented **[in the adjacent frame](/assets/images/gallery/factory-upstairs-expansion-hole-through-original-exterior.jpg)**;

on the flat face of the nearest joist a cursive graphite-pencil inscription reads 'AGOSTO 8 - 56' (August 8, 1956), a fourth dated pencil mark by the same hand or cohort as the three 'Marzo' 1952–54 dates on the east wall of the same room, and a thin black signal cable runs horizontally across just below the joist Pencil figure study drawn directly on the troweled stucco of an interior second-floor wall at the Hoffmann-Hayman factory — an informal mark left by an occupant of the building Close-up of an informal pencil sketch drawn in graphite directly on a troweled white-stucco interior wall on the first floor of the Hoffmann-Hayman factory, photographed on 11 March 2022 — at the foot of the stairs up to the second floor, right at the edge of a later-cut secondary doorway into a first-floor bathroom, where the wood jamb and a brass door hinge are visible at the right edge of the frame (with a section of twisted-fibre rope running through the gap at mid-height) and a thickened projecting stucco ledge crosses the top of the frame; the sketch itself is a schematic composition of an irregular pointed shape above a small rectangle with a horizontal line extending right (ending in a short vertical tick) and a vertical line descending below, reading loosely as a rough elevation-style diagram, and a torn-piece-shaped yellow-amber residue of aged masking-tape adhesive is soaked into the plaster at lower-left — a second human trace beside the pencil mark itself **May 2014** (**iPhone 5**) — **metal-roofed east-wing shed** at Hoffmann-Hayman: **printed Master Chef** plywood used as **interior sheathing**, **upside down** under joists — **COFFEE** / **MASTER CHEF** and **H AND H**-style **red** and **black** art still legible.
