` CONVEYER FOR BAKERS OVENS Filed March l2, 1949 2 Sheets-Sheet 2 Patented Oct. 2, 1951 UNITED STATES PATENT oFFlcE 2,570,150 Y ooNvEYER Foa BAKERS ovENs Boris M. Osojnak, Pittsburgh, Pa. Application March 12, 19.49, serial No. 81,165,`
This invention relates to a conveyor for bakers ovens and more particularly to such a conveyor having means for stabilizing the trays supported by the conveyor. In bakers ovens of the type disclosed in I-Ialler Patents Nos. 1,359,247 and 1,363,781, the bread or other article being baked i-s supported on trays which are carried by endless chains. These chains travel in a tortuous path over a plurality of sprocket wheels. The trays are pivotally mounted so that they will normally be horizontal. However, the chain motion is often irregular so as to cause the trays to swing, this resulting in the spilling of the contents or leaving an uneven surface on the nished product. The batter is often spilled over the burners, which requires the oven to be shut down and the burners cleaned.
It is an object of my invention to provide a conveyor in which the tray is maintained in a substantially horizontal plane under all condiat any point of travel.
This and other objects will be more apparent after referring to the following specification and attached drawings, in which:
Figure l is a plan View of my device;
Figure 2 is a schematic View taken on the line II-II of Figure l;
Figure 3 is an enlarged plan view of a tray supported on the chains; and
Figure 4 is a perspective View of a section of the conveyor and tray.
Referring more particularly to the drawings, the reference numeral 2 indicated the walls of an oven having an opening 4 in one side for loading and unloading the goods to be baked. The goods are carried around the oven on an endless conveyor made up of three endless chains 6, 8 and I8, which are supported by and driven from a plurality of sets of sprocket wheels. Each set of sprocket wheels consists of three wheels I2, I and I with the relationship of the sprocket wheels of each set being the same in all sets. Sprocket wheel l2 is mounted on a stub shaft IS arranged on the outboard side of the conveyor and supported by a pair of spaced apart bearings 20. The sprockets Iii and I5 are mounted on a common stub shaft 22 which is supported by a pair of spaced apart bearings 24. The axes of shafts I8 and 22 are parallel .but are oiset a distance 2% with spect to one another. A plurality of trays 28 are spaced apart along the chains and extend between the chains 5 and 8. Chain links 38 are connected by means of pins 32. For supporting the trays one of the pins 32 of the chain 4 Claims. (Cl. 198--138) 6 is replaced by a longer pin 34 which is fastened vto the tray 28, as shown. The left hand side of the tray 28 is supported on a pin 36, which extends from the tray through both of the chains 3 and I8, replacing the corresponding pins 32. It will be seen that the axis of pins 34 and 36 are parallel but are also offset a distance 26 in the same manner as the axes of shafts I8 and 22. The sprockets I2, I4 and I6 of at least one set are driven at the same speed from a motor 38.
The operation of the device isas follows:
When the motor 38 is rotated, the chains 6,
8 and In will rotate in parallel paths at the same speed. The trays 28 are pivotally supported by the pins 34 and 36 so that the trays will always be in a horizontal position. When the tray 28 tends to tilt about the axis 4U, which passes `through point 42 on chain' 6 and point 44 on chain 8, the tendency to tilt will be resisted by a force at point 45 on chain Il). The magnitude of this resistant force is determined by the perpendicular distance 48 between the point 4B and the axis 48. This resistant force can be varied by changing the distance 26 and also by changing the distance 5G between the sprockets 8 and I8.
While one embodiment of my invention has been shown and described it will be apparent that other adaptations and modifications may be made without departing from the scope of the following claims.
I claim:
1. In a conveyor, the combination including a pair of spaced apart sprocket wheels having 4their axes offset and parallel to each other, an endless chain mounted on each sprocket, a material supporting device extending between said chains, pivot means for mounting the ends of the material supporting devices on said chains, the axes of said pivot means being parallel to each other and offset with respect to each other in the same manner as the axes of the sprockets, a third sprocket wheel adjacent one of the above mentioned sprocket wheels mounted with its axis aligned with the axis of `the adjacent sprocket wheel, and a third endless chain mounted on the third sprocket wheel, the pivot means of the adjacent chain being supported on said third chain.

In a. conveyor, the combination including a pair of spaced apart sprocket wheels, a third sprocket wheel adjacentto and on the outboard side of one of said pair of sprocket wheels, a shaft extending through said third sprocket wheel and the sprocket wheel adjacent thereto, a second shaft for supporting the other of said pair of sprocket wheels, the axes of said shafts being offset and parallel to each other, an endless chain mounted on each sprocket, a plurality of material supporting devices spaced apart along the chains and extending between the chains mounted on the said pair of sprocket wheels, pivot means for mounting the ends of each of the material devices on said last mentioned chains, the pivot means adjacent the third chain extending thereto and being mounted thereon, the axes of the pivot means of each material supporting device being parallel to each other and offset'with respect to each other in the same manner as the axes of the shafts.
Y 4. In a conveyor, the combination including a pair of spaced apart sprocket wheels, a third sprocket wheel adjacent to and on the outboard side of one of said pair of sprocket wheels, a shaft extending through said third sprocket wheel and the sprocket wheel adjacent thereto, a second shaft for supporting the other of said pair of sprocket wheels, the aXes of said shafts being offset and parallel to each other, an endless chain mounted Yon each sprocket, a plurality of material supporting devices spaced apart along the chains and extending between the chains mounted on the said pair of sprocket wheels, pivot means for mounting the ends of each of the material devices on said last mentioned chains, the pivot means adjacent the third chain extending thereto and being mounted thereon, the axes of the pivot means of each material supporting device being parallel to each other and oiset with respect to each other in the same manner as the axes of the shafts, another set of three sprocket wheels spaced from the first three sprocket wheels andY arranged in the same manner as the first three, said chains being mounted on said last named sprocket wheels.
