p The invention relates to improvements in' conveyer slats and more particularly to aslat designed for use on binderv conveyers or canvases and an obj ect of the invention is to 5 yprovide a slat arrangement which will materially prolong the life of the canvas and which positively prevents any possibility of grain, chad, bugs and so forth getting loetween the slat and the canvas.

A further object is to lprovide a larly strong slat construction and also a slat having carrier members at the ends thereofy which reduce materially the wear on the edges of the canvas.

A further object is to constructy the device in a simple manner and such that the canvas can be provided with the slats at reasonable cost. Y

With the above more important objects in view, the invention consists essentially in the arrangement and construction of parts hereinafter more particularly described, reference being had to the accompanying drawy ing, in which i The conveyer or canvas lis of the usual type employed on binding machines and it is.

supplied at suitable intervals as is customary with cross slatsto gather and carry the grain. According to my invention,V the slats are all constructed as now described, reference being had initially to Figures l to 4 inclusive.

In carrying out the invention as shown in the latter figures, I'provide a wooden cross v slat 2 having a length approximately equal to the width of the canvas and a Width as is particu-` those parts of the canvas covering the'wooden Fig. l is a perspective view of a part of a tional view centrally and longitudinallyv usual and provided' on Ythe .underside with a plurality of spaced crossl channels'.

` Over each of these strips fpass the canvas which goes up one sidethe strip7 acrossthe top thereoil and down the other side as best` shown in Figures 2 and 4.@ I provide. 'also channel shaped metal strips 4 having a length vapproximately equal to the width of the can-` vas and which are adapted-to be placed over 3 strips 2. metallsvrips have. their "edges i extending downwardly below the sides of the Woodenst'rip: and-.formedv so that theyA willv inno waycut'thefcanvas.- ln the present ins stance, 'l have sli'o'w'n thegedges of themetal strips as rolled over wires 5 and'."

The metal strips are longitudinally corrugated as indicated-at 7 and this'serves notpnly toreintorcethe metal strips but also to causev them to better gatherlthegrain. The metal i strips'are fastened to the wooden strips byv relatively long rivets 8 which pass through the canvasandthrough the channels 3 hereinbefore 'mentioned'. rIChe canvases lor conn veyersof binding machines have their ends carried by supporting wood strips attached to the binder frame and as such is common practice and well known, the same are not'herein shown.

In order to guard the edges of the canvas and protect the samefrom unnecessary wear l by contact lwith such mentioned strips, I have provided carriers 9`on each end of the slat. These carriers are both identically constructed and each is in the form of a rela- 8 tively short channel bar l0, the up turned flanges l1 and 12 of which pass between the sides of thewoodstrip 2 and the passing portions of the canvasfstrip and are held by the end rivet 8. A vertical rivet 18 passes also through the inner end of each carrier and upwardly through the slat, canvas and strip 4. lt will be observed that the base 14k of the carrier is 'contained in a; lower horizontal 95 plane than the outturned ends of the canvas `so that when the canvas is in operating position within the binder' frame, the carriers 9 will ride the carrying strips on the binder before mentioned and not herein shown and will hold the canvas clear of thesame thereby materially saving the edges' of the canvas from wear.

It will be apparent from the above descrip- I tion that there is no possibility of grain, chaff,

Abugs or so forth getting underneaththe slat as so commonly occurs with the type of slats now used vand that thetype of Slat provided is particularly strong and durable and guards the canvas from rotting and pulling away from the slat as so `commonly occurs atthe;

present time. i Y

Vln Figure 5, l have shown a modificationV of the invention and in .this construction the wooden slat is entirelyT dispensed with and'in its place lhavc substituted a longitudinally corrugated, channel shaped,r inner strip l5.,

ln this type of construction, the canvas is caught between the inner s rip l5 and the outerlstrip and instead of employing a single relatiif'elylong end rivet 8 and a vertical rivet 13, utilize two pairs of short rivets 16 and l? to fasten the carrier in place.

1 What I claim as my invention is The combination .with a canvas conveyer,V

of a cross strip substantially rectangular in vertical cross sectionand over which the can-i vas is passed, a longitudinally corrugated channel-shaped strip overlying the canvas and having the side flanges thereof extending downwardly beyond the base of the former'.

strip, VVmeans permanently fastening the side flanges Aofthe outer strip to the inner strip,

said means passing through the canvas and carrier members, underlying the ends of the Y inner strip and extending downwardly beyond the out passing ends of the canvas strip. y
