iv Application filed January 12, .1927. Serial No; 160,582.

My invention relates to coolersfor cakes and food stuffs and the frosting placed thereon. I i

One object of my mechanical means for the rapid cooling of cakes and the frosting placed thereon. I

Another object is to provide means for automatically producing these results simula taneously upon varied forms of food products and at the same time providing for the 7 process, a continued action, and also pro-, viding a protection from dust and other foreign matter in the air. i p

With these objects in viewmy invention consists of the following novel features of construction and arrangement of parts as will be hereinafter fully described and pointed out in the claims, reference being/had to the accompanying drawings in which Fig.1, is a perspective side view of the ex-v terior of my device. Fig. 2,.is a side interior view in cross see- Fig. 3 is an end view in cross section of my device. i Fig. elis a side interior'view in cross section of afragmentary partof my device.-

Fig 5, is aplan View of a part of my device. p 1 i Fig. 6, is a perspective end view of my device. 1 The same reference characters denote like parts in each of the several figures ofthe drawings. I

In carrying out my invention I provide a rectangular housing A, having double parallel sides, top and end walls a, a, spaced apart and forming an outer and inner wall, the

housing having an open bOttOHL MThG top of the housing may be in a curved outline as shown in'Figs. 1 and 6. Within the housing I have constructed three vertical parallel partitions 5, 6, and 6; these partitions eX- tend downward from the interior surface of the inner top wall of the housing to a point near thelower edge of the side and end walls of the housing A. These partition walls are. composed of the central wall 5 and the two end walls 6 and 6, dividing the housing into 4 chambers, designated as A A A A. In the upper portion of each end partition wall 6 and 6 I have a circular opening 7 and mounted in any convenient manner in' each opening 7 I have the electrically operated fan 8 having a motor 9 connected therewith,

invention is to provide a mounted-on standard From thelower end of. each partition Wall 6 and 6 Ihave a floor l1 extending longitudinally from'the lower edge ofthe partitionwalltowards the central partition 5,; this floor alsoe'xtends across between the interior side walls of the I housing. An ,open space 12-extends betweenthe end offloor ll andcentral ,parti-* tion wall 5. Mounted horizontally between the end partition wallsa and the interior end wall surface of thehou'sing A, and between the partition wall6 and the interior of the endiwallsurface ofthe housing A,-I havea series, ofiblind slats 1.3, 13, 13,,piv0tally' mounted between the interior walls of the housing A andin the walls of the same, the lower edges of which slats are on a line with the floor 11 and Ihavean operating r0d14 linked in the usualmanner with the upper edges .oflthe blind slats13, 13, as shown in Figs. 2 andS and 4." Mounted on the outer" end of one of each of these series of blind slats and extending thru theside walls of the housing A, I have the crank handle 15.

for operating the blind slats for opening and closing; the lower-edges of the side and end walls of the housing A are removably mounted on the table'or other supports B inany convenient manner; also removably mounted on the supporting tableB, Ihave an elongated frame structure C, havingthe side and. cross bars 16 and 17 and the legs18, the size a and form of the frame structure C is such that the-housing A may be placed down over I the frame G, the legs 18 raise the frame structure, so asto'leave the open under space or passage way 19 betweenthe bar 17 and legs 18, and the top of the table surface B;

mounted in any convenient manner on the frame C I have a series of metal pipes or J tube structures D; this series of'tube struc tures D consists of the parallel connecting tubes or

pipes

20, 20, 20, and 20, 20, 20, in 5 horizontal alinement, one or more layers, one

over the other, such as I) and 0; mounted upon the tubing I have the connecting valve 21; these tubesare for. the purpose ofcontaining suitable air cooling refrigerating elemcnts; along rack O in housing A,.mounte'd in any convenient manneraround the outer sides and ends ofthe tube layers?) and 0, I

have a narrow sloping sideor wall stripE,

the upperedges of which are adjacent to the.

interior surface of the inner 'wallof housing.

A, and the lower edge adjacent to the upper layer of piping C; an open space 22 is left in each end wall of housing A below the lower line of rack bar 17 and above the surface of the table support B which permits of a passage way thru the housing A and under rack C and over the supporting surface B; on the surface B and thru the passage way 22 I have arranged an endless belt F which in movement rests upon the surface B and which may be operated in any convenient manner.

In the operation of my device having the table 01' platform B and the operative endless belt F in position as before mentioned, I arrange the electrical power connection for the movement of the belt I; on the table support B I mount the rack C, and on the rack C is mounted the piping D; having thus mounted the rack and piping, I surround the piping with the sloping strap or guard E for the purpose of more completely concentrating the air current against the tubes; 1 then place over the rack and piping the housing A, having in it the fans 8, 8 before mentioned and the electric motors 9, 9; the valve 21 controls the flow of refrigerating material; when the piping has reached the proper refrigerating temperature I supply the electrical power to the fans 8, 8 and the movement of the fans causes a circulation of the air over the piping D, and through the opening 12 and into chambers A, A and A as shown by the line of arrows in the Figs. 1 and l, and again over the piping and down into the passage way 22 and on to the "food stulfs and frosting 23, 23; the food stuffs are placed upon the belt F outside the housing, and are passed through the housing on the belt F and thus they come in contact with the circulation of the cold air as they are moving through the passage way 22, and the air in its passing is directed against the chilled tubing by means of the guard E around the piping D; I can control at all times the air current by the opening and closing of the

slats

13, 13 by means of the handle 15.

Having thus described my invention what I claim as new and for which I desire Letters Patent is as follows:

1. In a cooler for frosting, a portable housing having double walls and top, spaced apart, and open bottom, the interior of the housing divided by vertical partitions into a plurality of chambers, openings in the partitions in which operated fans are positioned, means for operating the same, pivotal blind slats mounted in the floor line of the chambers for controlling the outlet of air and the open space in the floor line of the adjacent chamber for the inlet of air, a platform supporting the housing and having thereon mechanical means for cooling the air after passing into the housing chamber and in passing out of the housing chamber, and means for automatically conveying food stuffs through the housing and in contact with the cooling air passing out of the housing chamber.

:2. In a. cooler for frosting, a rectangular housing removably mounted on a platform and having a. vertical opening in the lower edge of each end, vertical partitions dividing the interior into a plurality of chambers, an openingin one or more of the partitions, a fan mounted opposite each opening and means for operating the fans, each opposite end chamber of the housing having a raised flooring of blind slats, means for operating the same, two opposite intermediate chambers having each a raised flooring with an opening therein, a support removably mounted on the platform and beneath the flooring, refrigerating coils mounted on the support, and a belt conveyor passing through the housing.

In testimony whereof I have affixed my signature.
