OFFICE OHIO, FACTURING COMPANY, OF COLUMBUS, 01-110, A CORPORATION OF OHIO CONVEYER Application filed August 23," 1926. Serial No. 131,047.

' The means whereby I attain this object are fully set forth in the following specification and illustrated in the accompanying drawing of which Fig. 1 is a diagrammatic illustration of a conveyer of the type to which my present invention relates.

Fig. 2 is a fragmentary sectional view taken in a vertical plane extending longitudinally of a conveyer equipped with the devices of my invention.

Fig. 3 is a trated in Fig.

Fig. 4 is a fragmentary detail of one of the conveyer elements and the means of attaching it to the conveyer chain.

F 5 is a sectional view taken along the l1ne.V-V of Fig. 4. V L1ke numerals refer to similar parts in the several figures.

In Fig. l of the drawing Ihave diagrammatically shown at 1 and 2 two of the sugar mills included in ed to successfully squeeze the sugar cane to extract the juice therefrom. As here illustrated, the crushed sugar cane, commonly called bagasse, forms a mat 3 which travels successively through the mills of the train guided by conveyer. troughs such as the trough 4 conveniently disposed, between the successive mills of the train. -This matof bagasse is propelled along the trough 4 by a series of scraper elements 5 '7 and 8 attached to the head. shaft 9 and the foot shaft 10 respectively. The shafts 9 and plan view of the devices illusthe mat 3 of a train of such mills adapt 10 are supported in suitable bearings, and are driven" by suitable power devices, but as such devices are well understood in the conveyer art, more complete illustration and 'description is not thought to be required at this time.

The chains 6 are preferably composed of cast metal links ll'cach comprising a pair of side bars 12 formed integral with, a cylindrical barrel 13 positioned. adjacent one end of the link. The barrel 13 is pierced by an axial ASSIGNOR TO THE-JEFFREY MANU- aperture through which extends a pintle 14, 1

and this pintle also projects through suitable apertures in the overlapping ends of the side bars of the next succeeding link to flexibly oin said links together. Formed on the sprocket wheels 7 and 8 are sprocket teeth 15 which are adapted to project into the space between the side bars 12 and to engage the barrel 13 to drive the chain.

At spaced intervals along the chains 6 certain of the links are provided with attachment wings 16 formed integral with the side. bars 12 and projecting perpendicular to the Y length of the chain. To the wings 16 are see cured the transversely extending angle bars '5 which constitute the material propelling elements ofthe conveyer. The flanges 17 of the angle bars 5 bear against the forward faces of the Wings 16, and are secured in place by suitable attachment bolts 18. These i g perpendicular flanges 17 are adapted to engage and under other conditions it is preferable that the chain should travel in the reverse direction-causing the side bars 12 to trail after forward side of the attachment wing 16 tobe pushed thereby, thereby avoiding tensile 'strain-upon'the attachment bolts 18. To thisattached" to endless chains 6 in the manner bagasse, and to propel it along i the connecting barrel 13. I Ineither case, the o conveyer element 5 should "be placed at the end I have so'shaped the attachment wing'16 Y andthe side bars 12 that the conveyer elen1ent5 may be attached at either side of said 30 i v of links comprislng laterally spaced side bars o of, the side bars 12 and extend across the spaces included t veyer elements 'As'these devices have-been heretofore constructed, the flanges 19' of the conveyer elements constitute abutments against which the chain "with disastrous consequences.

intruded between the sprocket teeth and fragments of caneflber are compressed by the sprocket teeth l5, building up masses of fiber against which'said teeth abut to create pressnrestending 'to shear the attachment bolts 18,;detaching the angle bars 5 froIm n order to prevent the 'creati'onof such pressuresl have provided apertures in the flanges 19 through which material accidently the chain6 may escape, thereby preventing thejcreation of the disastrous strains above referred to, and materially improving the operation, and. increasing 'the life of the apparatus.

"What I claim is: J V V 1. In a conveyer ofthe class described, the combination with an endless chain formed and transversely extending connecting 'bodies, of a sprocket wheel having teeth adapted to extend'between said side bars to engage said connecting bodiesto drive the chain, and conveyer elements attached to said chain at spaced intervals having flanges which extend acrossthe spaces occupied by said teeth upon their engagement with the links, said flanges having apertures adapted to permit therethrough the escape of material 'accidently intruded between said, chain and said sprocket ,wheel as andfor the purpose set forth.

In a conveyer of the class described, the vcombination with an endless chain formed and transversely extending connecting bodies, of asprocket wheel having teeth adapted to extend between said side bars to engage said connectingbodies to drive said chain, attachment wings formed integral withthe' side bars of some of said links and'extending perpendicularlylto the length of the chain,

and having flanges which extend transversely of the chain across the spaces occupied by said teeth upon their engagement with'the links, saidflangeslhaving apertures adapted to permit therethrough the escape of material accidently intruded between said chain extending connecting bodies, and L-lights secured to certain of said links and having one flange extending perpendicularly to the length of said chain and their other flanges extended transversely of said chain and across the spaces between the bars constituting said links.

In testimony whereof I have hereunto set my hand.
