BAND-CUTTER AND FEEDER.

sota, have invented certain newand useful Improvements in Band-.Cutters and Feeders;

and I do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the :art to which it appertainsto make and use the same.

My present inventionI relates to band-eutters and feeders, and hasfor its especial object to provide means whereby more ellieient movements are given both to the cutter-bars and to the overhead feed-bars.

The invention consists of the novel devices and combinations of devices hereinafter described, and defined in the claims. y

The invention is illustrated in the' accompanyiug drawings, wherein like charactersim vdicate like parts throughout the several views.

Figure 1 is a view, partly in vertical section and partly in side elevation, showing a portion of a tln'eshing-machine and a band-cutter and feeder, the latter embodying my invention. l plan and partly in horizontal section and with some parts broken away and others removed, showing the cutter-bars, overhead feed-bars, and crank' for driving the saine. Fig. 3 is a detail in side elevation,v with someparts broken away and others sectioned approximately in the line w3 :c3 of Fig. 2, showing the cutter-bars, overhead feed-bars, and supports for the same. Fig. 11 lis a view corresponding to Fig. 3, but showingI the parts in different positions.

Of the parts of the threshing-machine or :separator proper the numeral 1 indicates the case or inclosing frame, the numeral 2 the threshing-cylinder, the numeral 3 the toothed concave, and the numeral 4 the lower or unl der serrated feed-pan,which feedpan receives a vibratory motion in the ordinary` or any suitable way by means lnot illustrated.

The numeral 5 indicates the hood of the band-cutteraud feeder frame, which hood, as is usual, connects with the separator-case 1in the vicinity of the cylinder 2.

` The numeral 6 indicates the feed-table, and the numeral 7 the endless conveyor, which Fig. 2 is a detail view, partly inA -runs` over the vsame and delivers the uuthreshed lgrain onto the vibrating feed-pan 4 of the separator.

.The numeral S indicates a transversely-extended crank-shaft mounted in suitable bearings 9 on the sides of the hood 5 and provided at one end with a pulley l0, over which ay power-driven belt (not shown) runs to impart motion to the said crank-shaft. p The cutterbars 11 are carried by this crank-shaft S,`and, as shown, they are providedwith bearingboxes 12, by means of wllich they are jourualed to the crank portions of said shaft. At their forward ends the cutter-bars are pivotcd to the depending free ends of links 13, the upper en'ds of which links are pivoted to suitable supports 14 on the hood 5.

The overhead serrated cutter-bars 15 are su pported at their forward ends from the hood 5 by links 16, and at their rear ends they are provided with projecting metal straps 17, which are pivotally connected at their rear ends to the cutter-bars 11,preferably to blocks orlugs 18, secured directly in front of their bearing-boxes The cutter-bars 11 are, as is usual, provided with a plurality of beveled knife-sections 1U.

It will be noted that the links 13 and 16 are each formed by a pair of laterally-spaced straps. The extensions 17 of the overhead `feed-bars 15 are also preferably aoi'ded by pairs of parallel straps which Work betwee the straps of cooperating links 13.

Prior to my present invention it has been customaryI to rigidly connect or integrally form the cutter-bars with the serrated overhead feed-bars, in which ease, of course, the intermediate links 13 have not been employed. I have found that more eiicent movements, both of the cutter-bars and of .the overhead. feed-bars, may be obtained by forming them separate] y and pivotally eonnectin g the same, as illustrated in the drawings.- Under the upward orreturn. movements of thev cutterbars the links 13 cause therear ends of said bars to rise higher and thento descend more rapidly than in the priorarrangement noted; also, the overhead feed-bars 15 are given an Aendwise movement more directly in the direction of the line ot feed to the threshingcylinder.
