Qctober 31, 194 ;,Serial Massages My invention. relates? to improvements in tray supporting racks and similar. devices;v

My invention relates more particularly to improvements in the, typezot tray supporting racks used in. bakerieskitchens ot large hotels and other placeswherea. considerable: quantity. of. pan ro'11s,dcughnuts, buns and other similar types ofv bakery goods are handled.

The principal. objecmofz the present. invention is to provide am improvedasupporting. rack of the type; described which. possesses. many advantages over those heretofore produced: including great.- err loading; capacityease. 0t; accessibility and: ease ofzmovement.

A further object is to provide an improvedtray rackzthah willz havve a plurality of rows of shelves extending outwardly radially from a common axis, supported 1151181101). manner that the entire unit may be. moved in, a. circular direction by grasping any shelf and swinging the entire unit about its pivot.

A furtherobjece of the inventiondsto provide a revolving tray rack of the. type described; that is. extremely; sturdy. and rigid; yet sufiici ently light so; that: any, ordinary, persomis ablestio=move the same:ab:out, at,.will..

A. further. object or the invention is to provide a. revolving-:tray rack. construction: of the: typesdescribedi that: canbe easily and: cheaply built and will. not; easily become. broken: or outrof. order even whenrsubiectedtorlong and'hard usages.

other objects, and advantages.- will be more: apparent. from; the following, description; wherein reference. is; had to the accompanying; three sheets :of drawings, upon which.

Fig. 1a is afragmentary cross-sectional view showing the manner in which'a supporting hook is fastened through the entire unit;

Fig. 2 is a"plan-sectional view=of my improved revolving tray r-ack taken generally on the lines 2'2' of Fi'g. l l

Aslthusgfandescribed, Irhaveprovided a base and. a. rotatable. octagonal frame which. is,.mounted thereon and capable of rotationuponthecombinedmadialrand thrusthearing. I45

Imonder, however to. support thisframe even unevenly, loaded, aswilLbe' laten explainedl have provideia plurality of; roller members 32: which arenuniversallyg;mounted.and. fastened. to. the lower. side. of. the :frame. 26. so. that a. portion of the .loadeofthezirame. and the trayswhichis supports will; be. carried: adjacentthe. sides of. the octagom.

otherwiseesecuredi tor the..-upright, legs of the angles!!! 7 Lprovide. alternate .-rows..o. tray. sacks-42'. which are spaced. approximately-ms. inches apart. and between the rows of racks 36. The racks 42 are similar in construction to the racks 36 and may have the inner ends thereof welded or otherwise secured to upright support members 44 which are secured at both their upper and lower ends to the frame members 26 and 28 by the strap members 48 and 50. The tray racks 42 may also be braced with a radial brace 52 and a cross-brace 54 and. be welded or otherwise rigidly secured at their inner ends to the upright angles 44 hereinbefore described.

With the construction thus described, it can be seen that I have provided a rotatable multiple tray support which provides in the normal height which is practical approximately 20 rows of racks, eight to the row, or 160 racks. And this in a space which is comparatively compact so that anyone of the racks is easily accessible and which has the further advantage of being capable of rotation, so that a person may stand in one position and, by v merely swinging the unit about its pivot, place trays or remove trays from any of the other rows of racks desired.

Multiple trays racks of the type described are sometimes inserted into ovens loaded with trays of goods to be baked, and frequently the meansfor supporting the same in the oven may consist of an overhead trolley arrangement. -Accordingly, in Fig. 1a, I have shown a hook member rotation of the entire unit upon the hook when the hook is supported by an overhead track or similar support.

While I have shown and described the preferred embodiment and one modification of the invention, it will be understood by those skilled in the art that changes and modifications may 51 which is rotatably fastened by a nut '53 to the flange. to which the upper end of the post member [6' has been connected. With this construction, the entire unit can be lifted bodily, the base 12 being rotatable upon the post [6, but being carried thereby.

' In the modified form of the invention which I have shown in Figs. 3 and 4, I have provided a base which includes the four legs 60 that extend outwardly from a central pivot 62. Each of the'lcgs are provided with roller casters 64 universally mounted so that the unit may be moved in any desired direction. Upon'the pivot 62 which may include a combined roller and thrust bearing 66, I have mounted center post 68 which may carry a pair of horizontal wooden frame members 10 and 72. These frame members extend sideways and connect to vertical post members 74 and 76. As thus far described, the multiple base 60 may support a rotatable frame which includes the center post 68 mounted in the bearing 66 and which carries the rectangular frame consisting of the upper and lower crossmembers 76 and 72 and the vertical frame members 74 and 16.

The vertical frame members 14 and 16 may have a plurality of tray racks 18-and 80 secured thereto extending in opposite directions from the sides thereof. Each of the tray racks may include a bracing structure having a longitudinal brace 82 anda cross-brace 84. Certain of the tray racks 78a and 8611 are extended a short distance further than the rest so that these may be grasped to swing, the complete unit about on its pivot. Y

For a comparatively high revolving tray rack of this type it is sometimes desirable to provide additional bracing to prevent it from becoming top-heavy, and accordingly I have shown a pair of angle members 90 and 92 which extend outwardly from the lower end of the post 68 and downwardly as shown at 94 and 96. The lower ends of these members are provided with a universally mounted roller caster 98. With this construction it will be comparatively easy to move the entire unit about, and any danger of the be' made in the exact details shown, and I do not wish to be limited in any particular; rather what I desire to secure and protect by Letters Patent of the United States-is:-

A revolvable trayrack construction including a supporting base, a vertical post member rotatably positioned thereon, said post having collars at its upper and lower ends respectively, radially directed angle members extending outwardly from said collars, polygonally shaped frames secured to said top and bottom angle members,

upright braces connecting said frames at their corners and medially of each side, tray supporting racks secured to each pair of adjacent corner braces and a row of tray supporting racks secured to each pair of adjacent medial upright braces.
