1 Claim. Cl. 198-20) This invention :relates to conveyers which, of which is designated at l0. The legs of the .while adapted for a variety of different uses or applications, may be employedwith special advantage 'in connection with pasteurizing ma- -6 chinery, of the type shown in my application corners at their bottoms likely to catch and strike I on even the slightest projection. The present invention precludes such corners from being caught and the operation being impaired and this espe- 1 cially at the discharge end of the conveyer, provision being made to insure smooth and easy transfer of the cans or similar containers off of the main conveyer and onto oil-take conveyers leading to any suitable point of deposit.
' a Another object of the invention is to provide a device of this character and having these advantages and which is extremely simple although durable in construction, reliable and effective in 25 sive to manufacture.
Other objects and advantages reside in cer- 1 tain novelfeatures of the construction, arrangement and combination of parts which will be hereinafter more fully described and particularly so pointed out in the appended claim, reference being had to the accompanying drawing'forming a part of this specification, and in which:
Figure 1 is a fragmentary view partly in iongitudinalvertical section and partly in elevation 35 showing one construction in which the invention may be embodied; and
Figure 2 is a fragmentary perspective view of the upper p rtion of the structure shown in Figure 1. v Referring to the drawing, the reference character C designates generally the main conveyer of a pasteurizing machine corresponding in its general construction to the main conveyer of the application abovereferred to. While only 45 a fragment of this main conveyer is shown, it be understood that it is of the endless type I and consists of. a suitable number of endless chains of which one is designated at it. Each endless chain consists of T-shaped links 24, the 5 adjacent ends of the cross members of the T- shaped links being pivotally connected together by pivot pins 25. Each pivot pin also serves as a pintle or axle for a roller 26 rotatably mounted thereon. These endless chains and it 3 their rollers travel about suitable sprockets, one
and the flanges of laterally alined links of the conveyer a plurality of gap rods or bridge rods each groove ll. For a portion of their length rest on and are suitably secured to a supporting T-shaped links are flanged outwardly as at 21 several chains are welded to the cross channels 30 which make up the belt or carrying apron of the conveyer. The arrangement is such that the cross channels in the upper run of the conveyer areinverted so that their side flanges extend downwardly and as these side flanges are a closely adjacent in this upper run, the body portions of the cross channels thereof present a substantiallycontinuous table-like surface. The construction as thus far described is identical with that disclosed in the application referred to above and reference is made to said application for a complete disclosure of the general construction of this main conveyer.
The present invention proposes to form in each of the cross channels 30 a plurality of grooves 3|, disposed closely adjacent each other and ex- 20 tending transversely of their cross channel and. consequently longitudinally of the main conveyer. These grooves 3| may have their ends deepenedso as to be rounded or beveled as indi-- cated at 32. 25
At the discharge or unloading end of the main 83 are provided, there being one such rod for these bridge rods lie within the grooves of the 80 cross channels which are at or approach the unloading end of the main conveyer. The dik mensions of the grooves and rods are such that y the topmost surfaces of the rods are coplanar with or below the top surfaces of the channels 88 i and, if desired, the inner ends of the rods may be beveled as at 34. The outer ends of the rods angle 35. If desired, the rods 33 may be welded as at 36 to the supporting angle 35. The angle 40 coplanar with or slightly below the top surfaces I i of the rods 33.
It will be understood that the bridge rods or gap rods 33 take the place of the corresponding bridge plate in my pending application and coacting as they do with the grooves of the cross channels of the main conveyer they provide for eiiective transfer of the cans or containers from I the main conveyer onto the unloading conveyers. Since all points or surfaces of the rods are disposed at or below the supporting surfaces of the channels of the main conveyer no projections or shoulders are presented on which the sharp 1 corners of the cans may catch.
While I have shown anddescribed one construction in which the invention may be advantageously embodied, it is to be understood that this construction has been selected merely for the purpose of illustration or example and that various changes in the size, shape and arrangement of the. parts may be made without departing from the spirit of the invention or the scope of the subjoined claim. I
surfaces adapted to support articles on the horizontal runof said main conveyer in an uprlilht position, an unloading conveyer at the discharge end of saidmain conveyer, said unloading con.- veyer also having its article supportingrun horizontally disposed andlevel with the article supporting run of the main conveyer, a plurality of transversely spaced, horizontally bridging elements extending between the discharge end of themain conveyer and the unloading conveyer, supportingmeans for the said bridging elements disposed below the article supporting surfaces thereof, said bridging elements having free ends extending into the spaces between the supporting surfaces of said cross members, the top surfaces of the portions of said bridging elements accommodated in said spaces being substantially coplanar with the article supporting surfaces of the main conveyer and unloading conveyer so that articles carried along the main conveyer will be pushed across the bridging elements and on to the unloading con- "veyer without striking or catching upon any obstructions of the device. 7 v
