Application filed November 10, 1921. Serial No. 514,413.

To all whom it may concern:

. Be it known that I, CALVIN C. NEWPORT, a citizen of the United States of America, and resident of Des Moines, Polk County, Iowa, have invented a new and useful Sectional Grain Sprouter, of which the following is a specification.

The object of this invention is to provide an improved device for the reception of grain during the process of sprouting.

A further object of this invention is to provide an improved elastic or sectional device adapted' to facilitate the artificial sprouting of grain.

A further ob-Ject of this invention is to provide, a sectional device of the class described, comprising a base or heating unit and a plurality of tray units adapted to contain the grain to be sprouted, the walls of said tray sections being formed with air chambers so arranged as to communicate when the several sections are collocated for use.

A further object of this invention is to provide improved means for rcmovably and replaceably mounting grain trays in the tray units. I

A further objectof this invention is-to provide an improved top section having a hinged top portion with a specially arranged stop brace and also provided with vents leading from its interior and from the airchamher or, space. v

A further object of thisinvention is'to provide an improved construction 'for glazed doors for the tray sections. 3

My invention consists in the construction, arrangement and combination of elements hereinafter set forth, pointed out in my claims and illustrated by the accompanying drawing, in which- Figure 1. is a front elevation illustrating "my improved device. Figure 2 is a vertical section of the same. F1gure3 IS a side ele- ,vation ofthetop section, dotted lines showin; the cover in partly open posit on. Figure ,4 is a plan of the top section. F gure 5 is a plan ot'the top section, the cover and trays being removed. Figure 6 is a plan of a tray employed in; the device. Figure 7 is a vertical section on the indicated line 7,7 of Figure 1, of one of the doors and on an en larig'ed scale.

with a knob handle 21L A heating device In the construction of the device as shown the numeral 10 designates generally a base section, on which are removably and re placeably mounted plurality of tray sec; tions 11, inth s nstance three in number,

all of which are surmountec ja s top tr l I section 11 provided with'a cover 12 hinged theretoat one margin. The base section 10' and tray sections 11,11 are rectangular in plan and elevation, and the base section 10 preferably is of materially greater vertical dimension than said tray sections. Thebase section 10 is composed of traifnes formedof wooden strips 13 on which are mounted walls'l l and a bottom 1 5"'ofsheet metal,

preferably galvanized. ,The' base section preferably is provided with sills 16 secured to its bottom, wherebysaidbottom iselevated above the supporting surface. The

base section 10 is provided with airelative'ly large open ng 17 n its front wall, and a door 18 is hinged atone side margin to a frame member 190i said wall an'dlis adapted to partially close said opening: 1'? .at'jtimesyas shown however. thevdoor 18 is of less/vertical dimension than the opening lflvvhereby aspace is left at the ,bottom'o f the door also is formed with a, ventilating port and such as a lamp 22, shown conventionally, is

vwhen closed for the" admission of ventilation to the section and device. Theldoor '18 r mounted in the base section lO'and rests loosely on the floor 15 thereof. A pan :23 is mounted in the'upperportion of the base'sec-y tion 10 and is spaced at its sides from the.

sidewalls 14 of said section whereby 'slotsor passages 24 are provided. leading from the interior of said base section throughthetop thereof, it beingnnderstood that said.

base section is open at its top except for the closure by means of said pain "The front wall of the base -section 10 preferably is tori med with ventilating slctea dj ent the front of the 13211123.. I r

Each tray section 11, 11? ft'ormedfpf frames 26 of wooden str ps to whichiare at tach ed metal side walls 27, saidsections be.

"Eng open at their bottoms and tops, save for the hinged cover 12 of the-uppermost section 11'? as, above noted. The sections 11, 11? areadapted-to be mounted inseries upon the base 10 and upon each other, the frames 26. resting upon the frames 13 of'said bottom section-or upon other frames-26 ,of

other tray sections, the walls 27 being in alinernent'with the walls 141 of the base sec- 7 tion. The traysections 11, 11 lso are formed with inner walls 28 spaced from the walls 27 whereby an air space or chamber 29 is provided extending from the bottom to top of each section on the rear sides thereof. The inner walls 28 or the tray sections 11, 11 are extended below the planes of the lower margins of the bottom fr 26. and outer side walls 27 of said sections, said projecting portions being offset or bent inwardly from the planes ol the inner wal s, and being designated by the numeral The projecting portions 30 of the inner walls are adapted to nest or fit snugly within the walls 28 01" the subjacent section, or, in the case of the lowermost oi the tray sections, within the pan 23 of the base section 10. in this manner the superposed sections are held firmly in position and accidental displacement by lateral movement is prevented. When the tray sections 11. 11 are so mounted, the air spaces 29 of said sections are continuous and communicating from the lowermost to the uppermost of said sections, and the bottom of the air space or chamber of the lowermost of said tray sections communicates with the slots or passages 24 between the pan and side walls of the base section, whereby communication is provided between theinterior of said base section and the surrounding air spaces or chambers of all of the superposed tray sections.

The frame 31 of the hingedcover l2 preferably is composed of strips which a re wiser than the frame strips 26 of the tray sections, and said frame members 31 when said co is in closed position, overlie and close the upper ends of the air spaces or chambers The side and rear outer walls 2"? of the uppermost tray section ll are formed with a number of vents 32, whereby a limited circulation of air from the air spa or chambers 29 is permitted when the cover 12 is provided or air from is closed. The cover 12 also with vents as to peimit escape the interior of the tray sections.

@n the "forward sides of the tray sections 11,11 the walls 27 and 28 are omitted, so

that the sections are open at'said forward sides except ashereinatter noted. Angle strips 3st are fixed to the inner "faces of the a inner side walls 28 of the tray sections and provide supports on which are slidably, re movably and replaceably mounted grain trays 35; two of said trays being; provided for each of the tray sections 11 and 11 The trays 35 preferably are formed of sheet metal with perforations 36 in their bottoms and are comparatively shallow. A stop strip 37 is mounted vertically across and projects inwardly iiromthe rear wall of each tray section 11, 11. It the it'unction of the stop strips 3'? to limit rearward movement of he tra s 35 and prevent contact thereof with the rear walls of the tray sections, whereby an air space is formed at the rear of the device between the rear walls and travs Each tray section 11, il -is provided a a door 38 hinged at one margin to its front of said doors is formed of a rectangular frame 39 of sheet metal which is mounted a sheet d0 oi glass. T i. for to mount the glass'sheets 40 in the o frames by stamping; or pressing hooks rearwardly from said frame (see the sheets 40 being received and held be tween said hoolrs and the main portions oz" 1; frames.

Each of the door 18, 38 is formed with short vertical slot d2 adjacent the margin opposite the hinged margin thereof, and screw eye is mounted in the adjacent frame member of the section on which each door is carried. The screw eyes arc adapteu to pass through the slots l2vi i the doors are closed and when said so v eyes ar turned a quarter turn so that they stand transversely of the slots they serve to prevent opening or the doors. Each of tire formed with a hook d6 on its opposite end.

The brace 45 extends between studs or nails d7, l8 carried; by the adyacent top Mame member 49 of said top section 11 and en tending across the space between t walls 119 27 28 of said section. When the cover is moved to its furthestlimit the hoolr the brace engages one oi. the studs or nails 47, d8 and prevents withdrawal of said brace from the space between the walls and also limits opening movement of the cover and serves to support said cover in open position. in a position inclined to the rear oi the vertical. its the studs or nails L7, 18 are spaced only suliiciently for free travel of the brace 4-5 between them, the engagement of one of said studs or nails by the hooked end of said brace is insured.

In practical use the device is assembled as shown and grain to be sprouted, particularly for use as poultry food, is placed in the trays 35. The grain is sprinkled with water as desirech and drip from the upper trays is received in turn by the underlying trays and finally by the pan 23., Heat is furnished by the lamp 22 and heated air from the interior of the base section 10 rises through the air spaces or chambers 29 of the walls of the tray sections and insulates and protects the interior of said tray sections from influence is is 01': cold atmospheric air, and a restricted circulation of air to and from the device is permitted by the vents 32 in the outer walls of the top section. The heating of the base section also causes an evaporation of water in the tray or pan 28, and heated, moist air rises from said base section through and around the perforated trays, and grain therein is caused to sprout and grow rapidly. The condition of the sprouted grain may be viewed at any time through the glazed doors 38, and any of the trays may be removed, by endwise movement on the strips 37, by opening the doors 38 The capacity of the device may be increased by adding other tray sections 11, or diminished by removing certain of said sections, so that the device may be adjusted in size andcapacity to the needs of each user.

I do not desire to be understood as limit ing myself to the precise construction herein shown and described, as various modifications, within the scope, of the appended claims, may be employed without departing from the spirit of my invention.

Particular emphasis is laid upon the advantage of employing this device for the sprouting of grain, such as oats, for use as feed for chickens during the winter season; thus providing during such winter season the kind of food most needed by the 'Eowls and which without a device of this kind it impossible to procure for them;
