Application filed December 1, 1921. Serial No. 519,036. 7

To all whom it may concern:

Be it known that 1, Isaac W. ENGLAND, a citizen of the UnitedStates, and resident of Passaic, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Conveyors, of which the following is a specification.

This invention relates to improvements in conveyors, and has particularreference to.

conveyors of the endless chain variety that are provided with means to support other parts on the links of the conveyer.

This invention is particularly adapted to support arms on the conveyer to retain 1 sheets orplates on edge while beingmoved through baking ovens, such as for baking lithographic ink on the plates.

The invention comprises novel details of improvement that will be more fully hereinafter set forth and then pointed out in the claims. I

Reference is to be had to the accompanyingdrawings, forming part hereof, where 1n- Figure 1 is a side elevation illustrating my improvements in connection with va baking oven; I

Fig. 2 is an enlarged detail plan view of a portion of the conveyer;

Fig. 3 is a cross section on line'3,.3,.in Fig. 2; Fig. is a detail perspective of one of the improved links of the conveyer;

Fig. 5 is an enlarged detail of part of one of the supports;

Fig. 6 is a cross section illustrating the conveyer having supports for metal plates or sheets;

Fig. 7 is a detail plan view of a modified form of the conveyer, and

Fig. 8 is a cross section of Fig. 7

Similar numerals of reference indicate corresponding parts in the several views.

The conveyer is shown comprising endless chains 1 spaced apart, being carried upon 45 sprocket wheels 2, 3, 4, j ournaled upon brackets 5, 6, carried by the frame 7 The chains may be propelled in any suitable manner, such as by means of pulley 8 on shaft 9 receiving belt 10 from a suitable 59 source of power. The chains of the conveyer illustrated comprise links, pins and rollers, some of which links are provided with laterally disposed ears or lugs to retain supporting arms or bars for sheets or plates 11. In

the form shown in Figsl'2 and 3 the links 12 are connected together in the usual way, having holes near their ends receiving crosspins 13 that have holesnear their ends receiving retaining pins 1 1, such as cotter-pins, rolls 15 on pins 13 being shown interposed between corresponding links 12 to space them. Links 16 are provided at opposite ends withholes' 17 to reccivethespaced.pins 13 of the conveyer chain, which'links 16 on opposite edges between holes 17 are provided with laterally extending earspr, lugs 18, spaced apartl Said ears or lugs are shown provided-with apertures 19 which oppose or register to re ceive supports 20. The holes 17 of links 16 receive the pins 13 and are retained onsaid pins by the retaining pins 14. In the form} illustrated in enlarged Figs. 2 and3 sup;

plemental'links 16 are outside of the main.

links 12 on one side of a chain and the'ends. of adjacent links 16 overlap one another, by preference ears 18 of one supplemental link 16 being longer than theears 18 of adjacent or alternate links 16 on opposite sidestherer of, so that the apertures 19 of the several sets of cars will bein alignment alongthe side of the chain, the alternate supports 20,

having corresponding width. In the-form.

shown inFigs. 7 and 8 the links 12. on: one side of thechain are dispensed with and the links 16 having the ears orllugs 18 consti; tute the links of such side of the chain, being supported upon the pins 13. While Figs 7 and 8 illustrate the simpler form of the two constructions described an advantage in the form shown in Figs. 2, 3, and 6 is, that if supplemental links 16 are to be re placed the said links can be removed without disturbing the continuity of the chain, since the links 12 will remain attached to pins 13 of the chain, whereas, if links 16 in Figs. 7 and 8 are to be removed the adjacent pins 13 of the chain become released on the corresponding side of the chain.

The supports 20 are shown in the form of wires having substantially straight parallel spaced arms 20 the wires or rods being bent into hook-like form at 20, connected together by the V-like portion 20eXtending between the arms 20 and bracing the same laterally. The free ends of arms 20 of each support 20 are passed through the registering apertures 19 in the ears or lugs 18 of the corresponding link, and respectively on op- I posite sides of the said ears or lugs the arms are swaged to produceproli'ections 21 to bear. against said ears to retain the supports 20 on the latter and prevent longitudinalimovement thereof. The corresponding ends of arms 20 may be inserted through the registering apertures 19 of ears 18 of the conveyer and the projections 21 then may be swaged on said arms, which projections may be bent back or removed in case it is desired to detach the supports 20 fromthe 'corresponding'links. Supports 20 may be removed and replaced with links 16 remaining, attached thereto by removing saidlink's from the conveyer chains.

In the example illustrated in Fig. 6, the

conveye'r comprises two endless chains, as

described -,'spaced apart, with supports 20 having their ends attached to ears or lugs l8'of links16 of said chains and located between the two chains which are to travel together,'sothat the supportsflO may project inf spaced relation from the conveyer in positionto receive sheets or plates 11 edgewise upon the 'c'onveyer, to be retained in proper position to travel with the conveyer. The

'chains may ,gli'de upon rails 22, passing through the baking oven or cha'mb'er23 of 'any'suitable construction, which is open at opposit'e' 'en'c'ls for the travel of the conveyer v toc'arry the plates edgewise therethrough.

An advantage of'the improvement set forth is that the ears or lugs 18 are an integ'ral or non-movable part of the links, so that there will beno' danger that the ears or will have movement relative to the links,jwhereb'y thesupports 20 will be retained in roper positions on the conveyer and will not be displaced as the conveyer travels, by which means the plates or sheets llwill be retained properly'in'spaced relation' on' the eonveyer.

Having now described my invention, what I claim is: I v

1. A conveyer comprising spaced'chains having side links and connecting pins, sup plemental links upon said pins adjacent to corresponding side links 'of thelp ins, and supports carried by and extending between opposing supplemental links of the spaced chains. 7 I

2. A conveyer comprlsmg spaced endless chains having side links and connecting pins, supplemental links upon said pins adjacent to corresponding side links of'the pins, the supplemental links having laterally disposed spaced apertured ears, supports having arms'locat'ed in the apertures of c'0rmeans to retain said tures of corresponding ear and means-to retain said arms upon said ears.

4. A conveyor chain comprising "side links and connecting pins, and supplemental links uponsaid pins outside of corresponding first named links, the supplemental links having spaced laterally disposed apcrturedears;

5. A chain'link having holes near opp'osite ends and spaced ears extending laterally from opposite edges of said link between said holes, said ears "having registering apertures. I
