Patented Oct. 25, 1932 UNITED STATES PATENT OFFICE HORACE H. MORGAN, O]? DETROIT, MICHIGAN, ASSIGNOR T PALMER BEI] COMPANY, O1 DE'IROIT, MICI-IIGAN, A COR-PORATION OF MIOHIGAN CONVEYER Application fi1ed March 17, 1980.

This invention relates t0 conveyers and more particularly to so-called carryall c0nveyers and has as one of its primary objects tesimplify, render more efficient and. im-

prove generally conveyer systems.

Ocher object-s of the present inventionare attributed 150 the novel constructionof the conveyer anc1 the connection of the load carrying means therewith which renders it possible t0 curve the conveyer in transverse planes and thereby greatly increase the field 0f use of the conveyer.

The construction 0f the conveyer and associated parts thereof as Well as the objects derivecl from its use Will be more readily apparent as this description proceeds, especially when considered in connection with the accompanying drawings, wherein:

Figure 1 is a fragmentary perspective view 0f a conveyer system constructed in accordance with this inverition.

Figure 2 is a view similar to Figure 1 showing ni0re part-icularly the manner in which the flexible driving member of the comveyer is supported fromthe track anal also the manner in which the load cairying means is connected to the driving member.

'Figure 3 is a fragmentary enlarged side elevational view of the conveyer.

Figure 4 is a sectional view tanken on the line 4-4 of Figure 2.

Figure 5 is a sectional view taken on the line 55 of Figure 2.

Figure 6 is a view similar to Figure 3 showing a slightly modified form of construction.

Figure 7 is a fragmentary diagrammatical view showing still another modification of the invention.

Referring 110W to the drawings, it Will 'be noted that there is illustrated in Figures 1 to 3, inclusive, a so-called carryall conveyer system comprising a chain 10 and members in the form of trueks 11 carried by the chain at longituclinally spaced points throughout the lengc-h thereof and carrying anti-friction rollers 12 engageable with a suitable track 13 for accurately guiding the chain in a predetermined path. The chain 10 is preferably of the roller type und is formed 0f aseries of links 14 comprising spaced side bars Serial N0. 436,615.

15 having the adjacent end portions thereof p1votally connected toget-her to f0rm tl1e chain by means 013 suitable pins 16 extending through the bosses 15 projecting inwardly from the ends of the bars 15. As shown par planes Without disturbing the load 011 the,

conveyer, I provide the following mechanism. As pointed out above, the chain is supportecl from the track 13 by means oi the trucks 11 secured 130 the chain at longitudinally spaceol points. These trucks are preferably arrangecl in pairs, as illustratecl in Figure 3 oftl1e drawings, anal the corresponding trucks of each pair are spaced from each other a predetermined distance. The distance between corresponcling trucks may vary in aceordance with the design of i3l16 conveyer laut, as shown herein, is substantially equal t0 the length ofpne 0f the chain units 0r links. In other words, the corresponding trucks are connected together by one 015 the links of the Chain designated in Figure 3 by the reference character 18. As shown in this latter figure, the corresponding truck members 19 and 20 are interposecl between the opposite ends of the chain unit 0r link 18 and the adjacent encls 0f the remaining portions of the chain and serve t0 establ ish a connection bet-ween the latter porti0ns Of che chain und the ends 0f the link 18 as will be presently set forth. Each 0f the truck members 19 and 20 are forrned with laterally extending spaced ears 21 anal 22 projecting towarcl euch other and spaced apart a suflicient distance to receive the end portions 0f the link 18. The ears 21 und 22 are provided with aligned openings having the axes thereof arrangedsubstantially parallel t0 the axes of the pins 16 and are adapted to receive the pins 28 Which serve 100 pivotally connect the link 18 to the trucks anal forrn supports for the rollers 17. It Will be unclerstoocl from the foregoing that the axes of the pins 23 also extend transversely t0 the axes of the rolls 12 with the result that these pins perform the additional function 0f pivotally connecting the ears to the opposite encls 01 the link 18 in such a manner as to permit a swinging movement of the trucks 19 ancl 20 relative to each other in a plane parallel to the plane of aclvancement of the chain, 01 as shown herein in a substantial horizontal plane.

The truck members 19 and 20 are pivotecl to the remaining portions of the chain by means of suitalole pins 24 extencling through the bifuroatecl bocly portions 25 of the trnck men1bers and having the axes thereof arrangecl transversely to the axes of the pins 23 ancl 16 and substantially parallel t0 ancl in the same vertical plane as the axes of the axles 26 f01 the track engaging wheels 12 0f the truck me1nbers. The connection betvveen the pins 24 ancl chain comprises suitable attaching elements 27 having portions extencling between the furcations of the bocly porti0n 25 ancl ournalecl upon the pins 24 ancl having spacecl ears 28 extending upon opposite sides 0f the portions of the ehain beyond the truck me1nbers ancl pivotally oonnectecl to the saicl portions 035 the chain by 1neans of the pins 16. Thus from the foreg0ing it Will be observed that the truck memloers 19 ancl 20 are not only capable 013 relative movement abont the axes of the pins 23 lont are also capable of relative movement about the axes 0f the pins 24 which are arranged transversely to the axes of the pins 23. In other worcls, the construotion is such as to permit movement of the conveyer in planes transverse to eaeh other as shown in Figures 1 antl 2 01 the clrawings.

Referring now more particnlarly to the means for supporting the loacl upon the conveyer, it Will be oloservecl froxn Figure 3 that the upper bar 01 the link 18 is provicled with upwardly extencling projections 29 terminating in oppositely extencling foot fianges 30 adaptecl to be securecl t0 a loacl carrying tray 31 by 1neans 01 the securing elements 32 The projections 29 1nay be either se cured to the link 18 in any suitable manner such as by Welding or by suitable fastening elements. VVhile it has been statecl that the loacl supporting trays a1e securecl t0 the links 18, it Will be notecl in Figure 3 that the loacl carriecl by the trays is distributecl ancl sup ported mainly by the truck members' 19 ancl 20. In orcler to accomplish this 1esult, the aforesaid truck mernbers are proviclecl with extensions 33 havin substantially fiat upper surfaces 34 for engaging the underside o1 the trays. The mecliurn. line of the surfaces 34 is preferably in alignment with the axes of the axles 26 so that the major portion 0f the load 011 the trays is carriecl by the trank eng-aging rollers 12 1nountecl on the axles 26. It should be unclerstoocl that the loacl supporting surfaees 34 011 the truck Inembers are not secu1etl to the tray but are capable 023 a sliding muve1nent relative thereto so that the truok members 19 ancl 20 1nay loe swung about the pins 23 without clisturbing the loacl car rying tray.

For curving the conveyer in a substantially horizontal plane, a seconcl track 36 n1ay be proviclecl. This track, as shown in Figure 1, is curved to a precleterminecl degree ancl is supported opposite the rollers 17 so as to engage the latter and eompel the same to follow the path cletermined by the track. The track 13 for the rollers 12 is likewise curvecl so as to insnre proper turning of the conveyer. It shoulcl be uncle1stoocl, however, that nu1ne1ous methocls 1nay be employecl for cleflecting the conveyer 0ut of its path of travel as cliagrammatically shown in Figu 1e 7 wherein a sprocket wheel 37 is rotatably mountecl upon the frame of the conveyer in a position to engage the rollers 17 antl the1ebj compel the chain to curve as illustratecl. In this connection it is t0 be notecl that the rollers 12 are arranged bolow the chain 01 driving member 10 thereby permitting a clriving or iclle1 sprocket to engage the chain fron1 the sicle without interfering with the trucks 01 loacl.

Referring now to Figure 6 of the draw ings, it Will be notecl that I have illustratecl a modifiecl forn1 of truck 1ne1nber. This truck member is especially clesigned for use in oonnection with conveyers where move- 1nent 01: the latter in a vertioal plane is n0t required and clifi'ers from the truck mernbers 19 ancl 20 in that the pins 24 clescribed in connectio1i with the latter truok members is dispensecl with, and the ende of the chain beyond the truck members, 0ne of which is il lustratecl in Figure 6 at 40, are pivotecl (li reotly t0 the truck members by means of pins 42 extending transversely to the path of travel 0f the chain. Thus it will be seen that the truck 1nembers are restrictel to turning movernent about the pins 42.

VVhile several modifications 01 the invention have been set forth above, it sh0ulcl be nnclerstoocl that reservation is macle to make such ohanges in the construction as may come with1 the purvievv of the accompanying claims.
