T0 all whom it 71mg/ concern.-

Be it known that we, ASA CLARK, ROBERT A. ASHLEY, and CHARLES ASHLEY, citizens of the United States, residing at Stockton, in the countyof San Joaquin and State of California, have invented certain newand useful Improvements in Endless Cutting Apparatus; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, referencebein g h ad to the accompanying drawings, and to the letters and figures of .reference marked thereon, which form a part of this specification.

Our invention has relation to improvements in an endless cutting apparatus for harvesters and the like; and the novelty consists in the peculiar combination, arrangement, and adaptation of the various parts for service, as will be hereinafter more fully Set forth, and particularly pointed out in the claims.

The invention and its advantages will be fully understood from the following descripy tures through which a bolt or rivet. is passed tion and claims, when taken in connection with the accompanying drawings, in which- Figure l. is a top plan of ourimproved endless cuttingapparatus for harvesters and the like, with parts removed to more clearly show the interior mechanism thereof. Fig. 2 is a detail perspective view of the linger-bar. Fig. 3 is a detached plan view of a portion of the endless chain, showing the links and plate, to which latter the cutter-blades are adapted to be Secured. Fig. t is a detail perspective view et' one of the guard-fingers, and Fig. 5 is a detail perspective view of one of the cutters.

Similar letters of reference indicate corresponding parts in the several figures oi' the drawings, in which- C denotes the nger-bar, consti-uci ed of wood or other desired material, said bar C being formed in its upper forward portion with a cut-away part or recess, in or upon which is adapted to be iitted an angle-iron bar, C. This finger-bar C is adapted to be seated and supported in the usual manner upon the timbers of the platform of an ordinary harvester, mower, reaper, or header, and the like. The forward vertical flange of the angle-bar C is provided with a series of apertures, by means of which the guard-fingers may be secured thereto. These guard-fingers B are of the ordinary pattern, having the usual longitudinal slot made therein. The guard-fingers are also provided at their rear end with a vertical plate or flange having apertures, as shown in detail. (See Fig. l.) By this means it will be clearly understood how the Fingers are attached to the forward vertical flange of the angle-iron C. To the inner side of this vertical wall I preferably secure a plate, e, which is designed to serve as a protection for the said vertical wall to prevent the same from undue wear caused by the endless cutter-chain striking it at that point.

F F designate rollers, around which is adapted to travel the usual apron or draper.Y

The endless cutter comprises the chain belt H, which is composed of links, every alternate one of which is provided with a horizontal cutter-carrying plate K, that is adapted to support a cutter-blade, A. The Said plate K and the cutter A are each provided with aperwhich securely holds them together, or they may be fastened in any other desired manner. At one end of the finger-bar C, preferably the inner, the chain l-I extends around a sprocketwheel, O, mounted upon a suitable Shaft journaled in the finger-bar in any preferred manner. This sprocket-wheel O is provided with a bevel gear-wheel, which engages with a corresponding bevel gear-wheel mounted upon a shaft, D, which latter is thereby adapted to drive the aforesaid cutter-chain.

At or near the other or outer end of the linger-bar the chain H is passed around a pulley, E, mounted upon a shaft journaled in a longitudinal slot, 72., formed in the finger-bar, the function of which will be presently explained.

It will be observed that by having the an gle-bar Cl constructed with the vertical flange and the finger-bar with the recess or cut-away part a guideway, I, is provided, as clearly shown in Fig. 2 ol' the drawings, which extends longitudinally the entire length of the ngerbar C, and in this guideway I the endless chain is adapted to travel.

It will be Seen from Fig. l of the drawings that as the chain travels along and within the guidewayl the cutters carried by the said chain slide and pass over the edge of the vertieal ilange of bar (l through the slots ot' the guard-fingers l.

ln order to prevent i he two parallel portions of the endless chain ll from striking and rubhingagainst each other, we provide a thin strip, a, preferably of wood, whieh is placed between the said portions oi the chain and extend along' the bar C, the path of the said ehain, and is firmly held in position by having its lower edge secured to the, horizontal portion oil the angle-bar C by suitable bolts or otherwise. This chain may be, il' desired, entirely housed or covered by securing a thin bar, P, of iron or other suitable material, at its t'ront edge to the upper surface olf the separating-plate u, and at its rear edge to the rear side ot' the finger-bar as clearly shown in Fig'. 2 oli' the drawings.

In the event of the endless chain becoming worn to suoli an extent that it will becon'ie loose or sag, or when it Vis found necessary to regulate the tension of the same in any way, we have provided a tighten ingdeviee, (marked (4,) as clearly shown in Fig. l of the drawings.

lt will be observed from Fig. l of the draw- Vings that the shaft carryingI the pulley .E journaled inthe slot in the bar C, (marked 7L.)

J is a post or brack et havi n a threaded b earing for the threaded tightening-rd j, such as usuallyT employed in machines of this character. The other ends of the rods have eyes that are adapted td eneirele the ends of the shaft earrying the pulley E.

Having described our invention7 what we claim isl. The bar (l, having its forward upper side recessed, as shown, in combinatioll with the angle-iron seeured in the saidrecess, the vertical strip u, secured to the angle-iron a short distance behind its vertical liang'e, the metallic strip l), secured upon the top of the har C and extending` over the strip a, the guard-lingers having` 1 )erforated attaching-flanges, the endless chain composed of the links and alternate] yar-ranged perforated plates upon which the cutters are secured, and means for driving the endless chain, substantially as specilied.

2. The coinbination, with the ba'r(f,havi1ngl i ts lorward upper side recessed, as shown, ot' the angle-iron secured in the said recess and having` the vertical 'flange perforated, the vertical strip a, secured to the angle-iron a short distance behind the vertical vflange, the chain composed of the links and alternately-arranged perforated plates, the cutters, the sprocket-wheel O at one endet' the finger-bar, the bevel-gear on the shaft D, meshing with the sprocket-plied, and the pulley .E at the opposite end ot' said bar, substantially as specified.

In testimony whereof we affix our signatures in presence of two witnesses.
