Parenteelv Feb. 11, 1808;'

To allY whom .it may concern:

Be it known that ISAAC F. MANNINd, citizen of the United States, residing at Ottawa, in the county of Lasalle and State of Illinois, has invented certain new and useful Improvements in Endless Conveyer Belts, of which the following is a s eciiication.

This invention re ates to improvements in that class ofendless 'conveyer belts, having side flanges or guards which prevent material being handled escaping at the sides of the belt. The object of this invention is to produce such a belt, available for use either to carry or elevate ear or shelled corn and other farm produce, or'for conve ing or elevating coal, sand, gravel, or other ard substances which would tend to rapidly cut and destroy a belt of fabric `or leather.

In the accompanying drawings Figure 1 is a perspective view of a known form of elevator frame for corn shellers, my improved belt being shown in position thereon. Fig. 2 is a perspective view of a section of my improved belt on a large scale. Fig. 3 is a detail erspective of one of the belt shoes.

Hldretofore it has beenusual to employ in the construction of elevators andconveyers` for corn-shellers and the like, sprocket chains provided at intervalsv with flights, said conveyers being mounted to travel over the I trough-like platform of the conveyor or elevator frame, and being actuated b sprockets on rollers or drums journaled in t e elevator frame at opposite ends of the platform. One

'objection to this type of elevator has been/ that the friction of the chains and load-on the platform h s required excessive power for operating t e elevator, and also it has been found that the material constituting the load to be elevated was liable to clog the sprocket chains or become lodged between them and the sprockets, thus occasioning delay/if not damage. f

In canyin out my invention I prefer to employ a be t of iiexible webbing or belting, obtainable in desired sizes in the market, because lof the ease with which it travels about its supporting rolls or drums and its great strengt as comparedy to its weight, ut I dol not confine myself to the use of said material. L

Referring to the drawings the belt proper A comprising an endless band of belting isv provided upon one side with a plating consisting of narrow' shoes B of sheet metal bolts or rivets b the ends of -the shoes being bent outward atl-ight angles to form .guar

sections B at either end of each'shoe, and the shoes being arranged lwith their edges closely adjacent or practically abutting so that the entire surface of the. belt is rotect.- ed by a sectional metal plating, t e bent ends of the shoes constituting a continuous sectional guard or flange at each edge of. the belt. -The several guard sections are extended at one edge b vto overlap the next adjacent section, and are of sufliciently greater width at the outer end than adjacent tothe belt to insure the continuit of the guard or flange 'at its outer edge W en passln around the rolls onwhich itma be mounte The outer edges of the guar sections are beveled or sloped from a point b2 to insure an absence of rojecting points asl the belt traverses a ro as shown m Fig. 3, and at the up er and lower ends of Fig. 1 the degree of s ope or bevel bel of course determined by the diameter o the rolls on which the belt is` to be mounted, as will be readily understood.'

The belt is providedy at suitable intervals with fl hts CA consisting of metal plates bent at one ongitudinal and both end edges to form flanges c c c which are riveted respectively to the body of the shoe B and to the guard sections B- at the ends thereof, as

shown. The main body of these flights is preferablynot at right angles to the belt and lts supporting shoe, but inclined slightly in the direction of the travel of the belt, and the outer edge C2 of each fli ht is bent or stamped secured transversely to the belting by belt to incline still farther orward in the direction of travelof the belt, preferably terminating at the forward edges b of the extensions of the guard sections, ,as shown, thus alfording at intervalsthrou hout the length f vof 'the belt recesses or poc ets which will carr fine material even though the opposite aps of the belt Ibe traveling in vertical planes. j

. Conveyer or elevator frames or machines des' ned for use with a conveyer composed .f

of c ains and flights may be adapted'for use with my improved belt ,by substituting elongated pulleys or rolls for the sprocket wheels and shafts, and substitutin ,supporting orM bearing rolls for the plat .orm. .`o`v`er which the cham conveyor travels. In `'constructing a frame for myv improved belt,

however, .the-broad side pieces of the carrier iframe are unnecessary as the `side guards "or the anges of the belt fulfil their function of preventlng material from dropping from the sides of the belt.

As shown in Fig. 1, a frame Well adapted to my belt may consist of stout side pieces 1 and endpieces 2, the ,journals of the rolls 3 on which the belt travels being mounted in bearings 3a secured to the under sides of the side Hieces. The small supporting or bearing -ro said side pieces, the rectangular frame thus described having any transverse or diagonal braces found' necessaryA to ive it the strength and rigidity required or the Work to be performed.

The belt.may be actuated by extendin v the journal of one of the pulleys 3 an mounting thereon a band-pulley crank or sprocket Wheel that it may be driven from s 4 are journaled atv suitable distances apart in bearings 5, carried by' any suitable source of ower and I contemplate also mounting a y-Wheel upon one of said shafts or journals to steady the travel of the belt.

' What I claim as new is A conveyer belt consisting of an endless flexible base, a carrier surface or plating comprising narrow metal shoes secured transversely on the base, and sectional guards or flanges carried by the shoes, each extended at 'one' ed e to overlap the next ad'acent guard, sai( guard sections being beve ed at.

the outer end. l

In testimony whereof I a'HiX my signature, in presence of two Witnesses.
