TBA Y FOR BREAD-COOLING MACHINES.
Application mearei r 15, 1924. Serial ire. 693,048.
This invention relates to improvements in movable trays, and more specifically to provements in trays desi ned for use incon junction with bread coo ing machines, and
which preferably have both sides thereof adapted tosupportloavc-s of bread or other The particular object of [the invention is to provide a tray comprising afra-m e having a pluralityof, transverse rodsor wires owed to each side thereof for the purpose of i supporting loaves of bread or other articles placed thereon. I
A further objectis to provide an open tray of simple and inexpensiveconstruction that will permit: access of airto the articles a a on the tray for thepurpose of cooling said articles. a 4
Other objects of the inventionwill more fully appear from thefollowing description and the accompanying drawings and will he pointed out in the annexed claims i In the drawings I have disclosed a structure designed to carry out the various objects of the invention, but it is to be understood that the invention is not confined to the exact" features shown, as various changes may be made within the scope of the claims which follow. i c i g In the accompanying drawings forming part of the specification: j
Figure 1 is a iew in side'elevation of portionof a bread cooling machine, partially in section, showing aeconstruction wherein thetnays are connected to an endless chain belt'to form in effect an endless conveyor;
Figure 2 is a cross sectional view on the line 22 of Figure 1, showing the means provided for supporting the trays when in use; p V
Figure 3 is a plan view of Figure 2;
Figure 4 is an enlarged detail view show ing the construction of the side frame members of the tray that receive the hooked ends of the transverse wires; I
Figure 5 is an enlargeddetail showing the manner of securing the wires to the frame member.
In'the selectedxembodiment of theinvention here shown, for the purposes of disclosure, I have illustrated a portion of a bread-cooling machine comprising upright posts 6, longitudinal guides or rails 7 and 8 adapted to support an endless belt 9,'a drive v sprocket 11, mounted upon ashaft 1mm a guide roller 13, mounted upon the shaft 12 for the purpose of guiding the ends of the trays as they pass around the axis of the shaft 12, from the lower guide rail 8 to the upper rail 7. j v i The importantvfc ature of this invention resides in the novel construction of the tray, which preferably consists of a rectangular frame comprising parallel side bars 14, pref erably of channel iron, having their ends connected together by means of transverse end bars 15, as particularly shown in Figure 3. As here shown, the ends 16' of the bar 15 are preferably bent at right angles andsecured tothe side beams by suitable means such as the rivets 17. Suitable tie rods 18 are preferably interposed between the side. bars 1.4 and function to retain the two beams in parallel relation.
The top andbottom surfaces of the tray are constructed preferably by meansof a plurality of spaced parallellrods or wires 19, arranged sufficiently closeit'ogether to prevent loav esofv bread, or other articles to be conveyed thereon, from falling therethrough. These transverse rods 1 or wires have their ends secured to the outwardly projecting flangesof the side bars 14:,- preferably by bending the ends 20 thereof around the flanges, as clearly shown in Figure 5'. Notches 21 are preferably, provided in the edges of the flangcs -adaptcd to receive the wires, as shown in F igure 4.; 1 'llhese notches function to prevent the wiresj-from changing their relative positions upon the bars-after having been secured thereto; By thus a1 ranging the wires 19 transversely of the frame, as above described and shown in Figure 3, loaves of bread and other articles placed thereon may readily be discharged therefrom by slightly tilting the tray as in c only. YVhen the tray is used as shown in Figure 1 pivot studs 22 are preferably provided on the end bars 15 adjacent the forward or lead ends thereof, and, in like manner, guide ro1lers23 are provided adjacent the rear ends thereof adapted to carry and support the rear end of the tray.
Another important feature of this tray resides in the simple and inexpensive construction combined with light weight, strength and rigidity, thereby providing a tray particularly adaptable for use in conjunction with bread-cooling machines to convey the hot loaves of bread thercthrough while cooling, the open construction of the tray being such as to permit free Circulation of air therethrough.
"I clai n'as mytinvention:
1.A tray comprising a frame having notches provided in the outer edges thereof, a plurality of transverse wires having their ends secured in said notches and forming the carrying surfaces of said tray.
2. A tray comprising a rectangular frame, having parallel side bars, spaced wires extending across said frame over the edges of said side bars, and means for locking said wires in position upon said bars.
3. A tray having a frame comprising side members and end members, said side members having opposed notches formed in the edges thereof, a plurality of wires secured to said side members and constituting the carrying surfaces of saidtray, the ends of said wires being folded and seated in said notchesto prevent movement of said wires on said side members.
t. A tray having a frame comprising parallel'flangcd side nember's, theouter edges of said flanges having a plurality of notches formed therein, a plurality of wires secured to said sidemembers andhaving their ends folded and seated in said notches, said wires forming the carrying surfaces ofsaid tray.
5. A tray having a frame comprlsing parallel flanged side members, with a plurality of spaced notches formed in the outwardly pro ecting edges of said side members, and
carrying surfaces for said tray comprising a plurality of spaced parallel wires having their ends folded and seated in said notches, and means for retaining said side members in parallel relation.
6. A tray having a frame comprising flanged side members with their ends secured together by suitable end members, outwardly projecting flanges formed on said side members and having a plurality of notches for'med therein, a plurality of spaced parallel wires arranged transversely on each side of said frame, the ends of said wires being folded and seated in said notches for the purpose of securing them to the frame.
7. The combination, in a bread cooler, with driving chains and operating sprockets therefor, of a bread carrying tray having pivotal connections in one end portion with said chains, guide rails for supporting the other end portion of the tray, wires secured to and held in spaced relation on both bottom and top of said tray, said wires being parallel to the line of movement of said chains, and whereby either face of the tray is adapted to receive and hold articles, and upon tilting said tray the articlessupported thereon will slide off the tray.
8. A support, a tray pivoted on said support, said tray having a frame comprising side members with their ends secured together by suitable end members, outwardly projecting flanges formed on said side mem bers and having a plurality of notches formed therein, a plurality of spaced parallel wires arranged transversely on both top and under side of said frame, the ends of said wires being folded and seated in said notches and between said flanges for the purpose of securing them to the frame.
In Witness whereof, I have hereunto set my hand this 11th day of February, 1924:.
