' This invention Arelatesyto a carrier chain of the endless type.

"Ihe principal objects of the invention are to provide a simple and convenient means for preventing the sagging of the means on which the load is carried; to provide this means in a psition in which .it will work directly beyond the iirst named means, where the advantage of the 1everageris at its best; to provide a simple means l0; for mounting the arbors `of the rollers which lact strandv of an endless chain, provided with a preferred embodiment of this invention;

Eig. 2 isa sectional View on the broken line 2--2 of Fig. 1. Y

Fig. 3 is aV View similar vto Fig. 1 of the lower Y strand,V and Fig. 4 is a section on the line 4-4 of Fig. 3. This invention is shown as applied to a form of endless conveyer having upper and lower strands or, at least a pair of strands, which may run vertically or in an'inclined direction. TheI conveyer is formed of two oppositechains, each comprising the usual links III, connected together I by hardened steel pins IIon which are mounted rollers I2 which run on a lower rail I3 and an upper supporting rail I4.

The load of the conveyer in the form of baskets or pockets, not shown, is carried on extended hardened steel pins I5 oppositely located at intervals on the two chains. two extended pins I5` of each pair on the two chains are located axially in alignment and support a rod or pocket or other element between them, this element constituting the carrying and load supporting part of the chain. Where these two pins are located on opposite sides they Vmay be arranged singly or in pairs, as desired. In

Y the present case they are shown as located singly. At this point two adjacent links I0 are pivotally connected by the pin II and a pin I5 extends inwardly from it. A side plate I6, having an opening I1 extending through it, extends outwardly from the chain. This plate extends outwardly. Itis rmly anchored between two pins, constituting a feature of the chain.

In other words, the

contact with one rail, pins extending laterally at Of course, on the upper strand this plate extends upwardly ancl for the Apurpose of the pres-- ent invention a third rail I8 is employed, th purpose of which will presently appear. y

- Each offthese platesl is completed as a guid- 5 ing means by the provision oi a hardened steel roller which is rotatably mounted on a stud 2l arranged vertically.; This stud is cylindrical, of course, and on one side at the top and bottom it is slabbed 0HV to lform two plane surfaces V22, these surfaces extending from each end inwardly to a point adjacent the rollers 20. These surfaces 22are spot welded to the plate VIIV above and'below the opening I'I, furnishing a stationary stud about which the roller is free to rotate.`

One of these plates is located on each side of the rail I3 or I8 and the rollers take care of theV tilting'. action due to the hanging of they load on the hardened steel pin I5. Also they take care of thereaction. f

It will be seen that the rails I3,- III and I8 can be made Vof commercial rolled T-.rail stock and not machined so that no expense for machining isre'quired. The rollers 20 ar'elocated right in the middle of the plates I6 between two pins Il, so that they take care 4of the tilting as wellV on'the upper strand as on the lower one and they are located in the most efficient kplace for re'- sisting any tendency on the part of the pins I5 to sag.

Having thus described my invention andthe advantages thereof, I do not wish to be limited to the details herein disclosed,l otherwise than as set forth in the claims, but what I claim is:-

1. In a conveyer, the combination of a rail, interconnected rollers in contact with the rail, pins passing through the rollers, outwardly extending pins located on the vi-lrst named pins at intervals for supporting the load, plates extending transversely from` the conveyer from each of said extended pins, said plates, each having a perforation therethrough, a stud secured to Said plate and arranged with its axis normal to the length of the conveyer, and a roller on the stud freely rotatable and adapted to extend through said perforations and engage a guide rail to prevent distortion of the extended pin.

2. In a conveyer, the combination of two rails in vertical alignment, interconnected rollers in intervals for supporting the load, a plate extending outwardly from the conveyer and parallel with the sides of the conveyer from each of said Y pins, and a roller carried by each plate and free. ly rotatable and adapted to engage the other rail on its inner side to prevent distortion of the extended pin.

3. In a conveyer, the combination of a pair of rails, a third rail beyond one of said rails, a conveyer chain composed of links and rollers, said rollers engaging surfaces of the first two rails, means carried by the chain and extending laterally for supporting a load, plates extending outwardly from said load supporting means, and rollers carried by said plates and extending toward and engaging the third rail, for the purpose described.

4. In a conveyer, the combination of a pair of rails, each having a surface on the same side for supporting a conveyer chain, a third rail beyond one of said rails, a conveyer chain composed of links and rollers, said rollers engaging said surfaces of the first two rails, means carried by the chain and extending laterally for supporting a load, plates extending outwardly from said load supporting means, and rollers carried by said plates and extending fromV the inner side toward the third rail and engaging it, for the purpose described.

5. In a conveyer, the combination of a pair of rails, each having a surface on the same side for supporting the two strands of a conveyer chain, a third rail beyond one of said rails, a con- Veyer chain composed of links and rollers, said rollers engaging Isaid surfaces of the first two rails, means carried by the chain and extending laterally beyond the chain for supporting a load, plates extending outwardly from said load supporting means, and rollers carried by said plates and extending from the outer side toward the third rail, for the purpose described.

6. In a conveyer, the combination of supporting rails, a chain composed of links and rollers, said rollers resting on said rails, pins extending through certain of the rollers, the links of the chain connecting said pins, means carried by said pins at intervals and projecting from the side of the chain for supporting the load, plates extend- Vto engage the guide rail to prevent tilting of the chain.

7. In a conveyer, the combination of a rail, interconnected rollers in contact with the rail, pins passing throughl the rollers, outwardly extending p-ins located on the first named pins at Aintervals for supporting the articles to be conveyed, a plate extending outwardly from the side of the oonveyer from each of said extended pins, said plate having a perforation therethrough, a freely rotatable roller rotatably supported by the plate extending through the plate, and a guide rail above the rst named rail which the roller is adapted to engage.

8. In a conveyer, the combination of a supporting rail, a chain composed of links and rollers, said rollers resting on said rail, pins extending through the rollers, the links connecting said pins, means carried by said pins at intervals for supporting the load, plates constituting arms of the links of the chain and extending outwardly, a guide rail in the plane of said rail, and rollers mounted on said plates and projecting inwardly from the plates to engage the guide rail to prevent tilting of the chain.

9. In a conveyer, the combination of a rail, interconnected rollers in contact with the rail, pins passing through the rollers, outwardly extending pins located on the first named pins at intervals and in alignment with the iirst named pins for supporting the articles to be conveyed, a plate extending outwardly from the side of the conveyer from each of said extended pins, said plate having a perforation therethrough, a guide rail and a freely rotatable roller supported by and extending through the plate and adapted to engage the guide rail.
