- 2,272,102 ELEVATOR CANVAS Thomas Williams, Emigrant, :Mont. v V r Application November 30, 1940, Serial N0. 3-68 ,051 I 1 Claim. (01. ms-+199) Y The present invention relates to an improved elevator canvas or apron particular y for d,

ers, combines, reapers, threshing machines, etc. However, it will beunderstood that an elevator canvas or apron constructed in accordance with the present invention may be used for any purpose for which. itmay desirable. j

An important provide, in a manner as an elevator canvas of the which will be free of the usual buckles, straps, rivets or staples and wherein the ends of the belt are held together bylacing.

Another very important object of the invention is to provide an elevator canvas of the aforementioned character comprising slats of a novel construction and arrangement.

Other objects of the invention are to provide an elevator canvas of the character set forth which will be comparatively simple in construction, strong, durable, highly eflicient and reliable in use, light in weight and which may be manufactured at low cost..

All of the foregoing and-still further objects and advantages of the invention will become apobject of the invention is to hereinafter set, forth,

be found adapted and? 7 connection. Sewed on the inner longitudinal marginal portions of the belt I are strengthening in place is indicated byrthe character 8 and character described parent from a study of the following specifica-fl tion, taken in connection with the accompanying designate corresponding parts throughout the several views, and wherein:-

Figure 1 is a top plan view of an elevator canvas constructed in accordance with the present invention, portions thereof being broken away.

Figure 2 is a view in side elevation of an intermediate portion of the canvas. 1

Figure 3, is a bottom plan view looking at the connected end portions of the belt from the line 3-3 of Figure 2.

Figure 4 is a cross sectional view, taken substantially on the line 4-4 oi Figure 2.

Figure 5 is a fragmentary view in vertical longitudinal section, taken substantially on the line 55 of Figure 4.

Figure 6 is a detail view in cross section, taken substantially on the line 6--6' of Figure l.

Referring now tothe drawings in detail, it will be seen that the embodiment of the invention which has been illustrated comprises a belt I of canvas or other suitable flexible material. The end portions of the belt I are'folded at 2 and stitched for providing a double thickness of material in which eyelets 3 are mounted. The

eyelets 3 accommodate a lace 4 of suitable material through the medium of which the ends like characters ;of reference of the belt I are adjustably and detachably connected. One end'ofjthebelt'l terminates. in a flap 5 which is adapted to extend over the laced or reinforcing strips 6 of suitable flexiblematerial. The stitching which secures the strips 6 extends longitudinally of the belt.

At longitudinally spaced points folded'transversely and stitched in a. manner to form upstanding loops or pockets I.---The end 2 portions of the transversely extending pockets 1 are flattened and secured to'the canvas "I by the same stitches 8 which attach the strips 6. Then,

one end portionxof the loops forming the pockets I is-cuttransversely, as at 9, to form openings for said pockets. Thisis shown to advantage'in Figure 6 of the drawings. The other ends of the pockets 1 remain closed." I l I The pockets-l are for the reception'of remove able rods Ill of suitable metal. :Of course; the

rods ID are inserted in tlie pocketsflj at the open I ends 9 of said pockets. The rods III are of sufeo '25 ficient length to project a slight distance beyond the open ends 9 ofthepockets- Formed in the rodslfl, adjacentthe open endsof the pockets, are;circumferentialgrooves or channels II. Pass- .ing through the stitched lower portions I2 ofthe pockets 1, adjacent the open ends of said pockets, are ties I3. 1 As also shown to advantagein Figure 6 of the drawings, the ties l3 are adapted to be drawn around the pockets! for gathering and contracting said pockets in thegrooves II for securing the rods III in said pockets. f

It will thus be seen that an elevator canvas hasbeen provided which is free of buckles, straps, rivets, etc. Throughthe medium of theeyelets 3 and the lace 4 the ends of the canvas may be expeditiously'and securely connected. It will also be observed that" the rods I0 constituting the slats are mountedand-held on the canvas without the use of metallic securing elements. Should oneof the rods Ill be bent it maybe expeditiously removed for repair orreplacement. To accomplish-this it is only necessary to untietheties 13,- The stitching 8 extending throughthe end portions of the pockets as before described, will tend t'oprevent the stitching of the pockets extending transversely of the belt, from tearing -.loose from stress acting longitudinally of the belt. The strips Gaalso assist inpreventing the pockets from tearingout bybeing secured'to the end portions ofithe pocketsby the-stitching'B.

I It isv believed that themany advantages of an the belt 1 s is I viding integral, tubular pockets, said pockets being open at one end and closed at their other ends, rods removably mounted in the pockets, said rods having circumferential grooves therein, and flexible ties positioned directly in the grooves at the bottom of the pockets and extending outwardly of the pockets transversely across the top thereof for gathering and engaging the material of said pockets in the grooves for removably se- 10 curing therods in said pockets.
