ICE-CREAM CABINE Application filed December 10, 1321. Serial No. 521,432.
To alZw/iom z't may concern Be it known that I, EDMOND N. Bounnon,
of the city of Chicago, county of Cook, and State of. Illinois, have invented certain new and useful Improvements in Ice-Cream Cabinets, of which the following is a specification.
My invention relates to new and useful improvements in ice cream cabinets, and'has for its main object the provision of an unleakable ice cream cabinet.
Another object is the provision of such a cabinet with means for continuous fresh air ventilation for its hollow walls, and the provision of drainage means for said ventilating means.
Another objectis the provision of a cabinet which is simple and durable in construction, highly eflicient in use and economical in manufacture.
he usual cabinets on the market are provided with linings which readily get out of order from continuous packing and stamp ing of the ice around the ice cream containers in said cabinets, and soon become leaky, as a result thereof. 1 overcome such objections and defects in construction by constructing my abinet in such a manner that it will not leak even if the inner lining is cracked or broken.
.Other objects will appear hereinafter.
The invention consists in the combinations and arrangements of parts hereinafter described'and claimed.
The invention will be best understood by reference to the accompanying drawings forming a part ofthis specification, and in which, i
F 1 is a perspective view of my improved cabinet,
Fig. 2 is a horizontal sectional view of a portion of the sidewall, taken along line 2-2 of Fig. 1,
Fig. 3 is an elevational view along line 33 of F 5, showin the frame work of the walls, the tarred felt between the yer-- tical and lateral members being mostly omit ted. for clearness of illustration,
Fig.4: is a fragmentary vertical section of thewall a11cl floor, taken on line 4. 4 of F ig. 5, showing the arrangement of the I various elements of the wall and floor, and
also of the ventilatin and drainin means a g V a Fig. 5 is a broken plan view of the cabinet,
and a citizen of the United States, and a resident.
Fig. 6 is a vertical section through the fioor,'taken on line 6-6 of Fig. 5,
The form of my invention illustrated in thedrawings consists of a cabinet comprising two compound side walls 10 and two compound end walls 11, each of which is arranged for ventilation by fresh air; a compound floor 12 composed of a plurality of layers, ofvarious materials; means for ventilating and draining said compound walls; and means for draining the interior space of the cabinet.
The cabinet will be furnished in various sizes andshapes, the medium size being about 21 inches wide, 47 inches long, and 30 inches high. The frame work of the medium sized cabinet comprises four corner posts 1%, for which 2 by 4i wood posts are preferably used, and between said corner posts, four floor sills 15 are fastened by means of nails or screws, or in any suitable manner, said sills being preferably 2 by 4: wood posts, laid with the narrow 2 inch side vertical, as shown in Fig. 3. The corner posts extend a few inches below the floor sill to form legs or supports for the cabinet. Upon each floor sill adjacent the'outer edge thereof, I erect a series of uprights 16 preferably 1 by 2 inches in cross sectionand spaced 2 inches apart, providing a series of ventilating spaces 17 between said uprights, as shown in Figs. 2 and 3. A layer of tarred felt 18 is placed on the outside of said upright 16 and a layer of wall board 19 is placed ex? 'terior of said tarred felt. On the outside of board or strip 21, an intermediate board 22,
and a lower board 23, each being preferably ;I-s by 1 inches in cross section, and gs inch cork slabs 24 and 25 fill the spaces between said boards or strips, as indicated at the left hand side in Fig. 3. A layer of tarred i :Eelt 26 covers the side of said boards and spaced 2 inches apart providing a series of.
air spaces 29. The lower board 23 and the layers oi. :t'clt 26 andQ'T do not rest upon the sill 15, but extendabout of an inch above the sill as shown in Figs. 3 and 4:, to provide a space or channel 30, which affords comnunication between the adjacent ventilating spaces of each series and between the oppo siteones ofboth series of spaces, and also provides, communication between the spaces ofthe several walls,as indicated in Fig. 1.
I provide an inner par "ition-or wall section which comprises a layer of wall board 31 placed ad acent the upr1ghts28, a layer of tarrcd felt 32 placed on the inner side of the wall board, and a lining of sheet metal 33 which forms the inner lining of the cabinet. The floor is a compound one, composed of a plurality otsuperposed layers-of various materials. Several cross beams 35 (see Fig. 6,) preferably consisting of 2 by 4 creosoted posts, connect the'side sills 15, intermediate the end sills, and beneath the sills and said beams 35 a sheet of metal 36 .is fastened forming a bottom layer of the cabinet. Strips of cork 37 are placed between said beams 35, abovethe metal sheet 36, and floor boards 38 of the usual {33s inch material rest upon said beams and sills. Upon said floor boards, a layer of wall board 39 is placed, thereon a layer of tarred felt 40,
and upon the same a lining of sheet metal 41 forming the inner floor lining of the cabinet. Said floor lining 41 is made continuous with the'shect metallining 33 of the side and end walls, or is soldered or otherwise fixed thereto to form air-tight and water-tightjoints. i
The means for draining or removing the brine from the cabinet comprises a 1 inch metal pipe 43 laid in the lower inner corner ofthe :cabmet, close to the inner lining.
The inner end or intake 4% of the pipe is" placed 2 inches above the floor, withthe endopening positionedtowards the inside of the cabinet, so that 2 inches or cold brine are continuously left inthe cabinet to racihtate cooling the same. The pipe exl'ends through the wall and into a 4-way connection 15 which is provided with refinovable plugs 46. for inspecting and cleanng out the connectlon and the pipe. Said connection 15 is oined by a sh rt pipe 4? with asimilar 4-way connection 48 provided with .a'plug 4:9, and connected to a depending pipe 50 which leadsto the sewer. The
end towards the cabinet of the connection 4:8 is' oined to the ventilatlng mechanism.
the opening 55.
In addition to the air spaces within the walls of the cabinet,as previously described, I provide means for sup-plying fresh air to said wall spaces in order to properly ventilate said walls, said means being furtherand the channel 30, and leadinginto the i-way connection 52, "fastened to the lower end of the floor. Said connection 52 is proride-d with clean-out plugs 53, and is connected to a 3-way valve case -54 of any suitablcconstruction, which 18 in turn connected to said i-way connection t8 and through it to the sewer, thus providing means for draining the walls of the cabinet. The valve 5-iis provided with a fresh-air inlet or opening 55 at the upper end, and with a valve handle 56 for controlling said valve, and. -whercby the passage 51 and the connection 52 may be set to communicate with either the opening 55 or wlt-h the drain connection 48 alone, or with both of them, or may be closed from both the connection 48 and The upper end of the walls is provided with suitable top strips 58, and the outside horizontal and vertical edges of the cabinet maybe provided with suitable trimmings 59 and 60, respectively, of metal or of. durablewood. A ledge or depression Gl'is also provided around the inner edge of thetop for. receiving a suitable cover (not shown) for the cabinet, such cover being preferably constructed of material and in a manner similarto the floor previously described. i
It will be observed from the above description and from the drawings, that the 7 layers of tarred felt are placed on the inner side of each partition to prevent moisture from getting into contact with the layers of wall board and of wood, and placed in said partitions, where the moistureis more a pt to leak through to the next partition or section. This construction thus makes the inner face of each wall and section-substantially impervious, and. in tact makes three walls, each of which presents an imnct. It will alsobeobserved that continuousventilation by means of freshair is provided tor thewalls of the cabinet by means of thevalve' 54, and the air inlet 55,- and that said ventilation may be intermittent by placingthe inlet 55 in communication with the lway connection '52 and therethrough with the air passage 51. and that said connection may be closed entirelyif desired. It is also evident that the 3-way pervious face toward-the inside otth'e cabi- 1 j V vvalve'5i may be set to provide ventilation for the spaces in the walls and simultane ously to'provide drainage means for the preferred form of construction for carrying spaces;
ing from the spirit of the invention. I
my invention into effect, this'is capable of variation and modification without depart- 7 therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.
