Fig. 3 is a side elevation of to discharge its load, is made to actuate said carrier, as far apart as practicable within the frame of the cutting machine.

B is the lower carrier shaft, arranged at right angles to the shaft D and having a bevel gear d, fast on the end adjacent thereto and meshing with the gear d (or 01 for actuating said shaft.

The lower end bar of the cutter frame is indicated at 4:, and to this is secured a compound box f, composed, preferably, of two parts, as shown in Figs. 6, 9 and 9, bolted together at their upper ends to the intermediate end bar 4 and provided at their lower ends with an eye-bearing at f, through which the shaft B extends loosely, said eye-bearing being enlarged at the end f, to receive the short tubular stud 6 on one of the boot side castings C, in which the shaft B is journaled, while the stud in turnis journalcd in the eyebearingf The outer side casting of the carrier bootis similarly provided with a sleeve (6) which is journaled in an eye-bearing b in an upright bracket or stand I), the shaft vB passing also through said sleeve and being journaled near its outer end therein. The carrier boot is thus pivotally supported in the brackets 19 and f and the whole weight of the carrier rests on the pivots on which the angle of the carrier is adjusted, instead of upon the carrier shaft, as heretofore, thereby facilitating such adjustment and relieving wear and friction at that point. The shaft B, immediately adjoining the boot sides 0, has sprocket wheels B fast on it, through which motion is imparted to drive chains passing over pulleys fast on a shaft a, at the upper end of the carrier for actuating the carrier flights, in the usual manner.

The boot side plates 0 are provided, each, with a semi-annular flange or rib '7, underlying thelower portion of the sprocket wheel adjacent thereto and extended tangentially to the arc of a circle of the curved portion,over the hopper side of said wheels for preventing the cut material from getting into the openings in the bottom board of the carrier for the carrier sprocket wheels or into and clogging said wheels and the chain operated thereby. The preferred form or construction of these boot sides is shown in Figs. 2 and 5,the former showing an outer and the latter an inner side View of the plate. The concave bottom 9 is stiffened by ribs 11 and is provided with lips 12 which engage sockets in the outer edge of the plates 0 and serve to lock the two parts together, preventing relative movement or displacement. The upper portions of the boot sides above the shaft B are extended to form arms 15, to which the sides 0 and bottom C of the carrier frame are attached, the latter having recesses in its lower end adjacent to its sides similar to those at c (Fig. 4) in its upper end, for the carrier driving sprocket wheels to project through. The sides are further'provided at the inner edge of the concave bottom, with offsets in the form of sockets to receive a cross bar or board, which in connection with long bolts passing from side to side through the holes 14, serve to stiffen the connection of the side plates, the board 13, serving also to form an extension of the front of the hopper resting thereon and an extension of the boot bottom.

The receiving hopper for the bootis composed of the lower ends of the carrier bottom and side boards, fan-shaped ortriangular side boards or

plates

1, 2, a front board 3, facing the bottom board and a machine end board 5 extending from the lower bar 4t to the upper end bar of the machine frame and cut out on its upper edge to match and fit snugly the discharge spout, indicated by dotted lines in Fig. 1. The fan-shaped

boards

1 and 2 are fastened, one (2)'to the carrier side and the other (1) to the front hopper board and are arranged to fold or pass, one by the other, as the angle of the carrier is adjusted to different degress of elevation or foltransportation. The hopper board 3 with the fan-shaped board secured thereto is adjustable with the carrier, but resting lightly upon the boot sides 0, in sockets 0 formed therein, and on the board 13 and moving with the carrier frame, when the latter is adjusted, by reason of the frictional contact of the overlapping, fan-shaped,

side boards

1 and 2, it can, when desired, be adjusted independently for expanding or contracting the mouth of the hopper, as re-' quired. The outward throw or movement of the end board 3 may be limited by any suitable stop onthe machine frame.

By locating the carrier actuating shaft low down and at the side of the machine upon which the carrier is arrranged to discharge the cut material, it will be apparent that the carrier can be set to much nearer a Vertical position than where the shaft is under the ordinary central arrangement, without interference from the extended machine frame, or the overhanging wheels or cutting cylinder, thereby, to that extent, reducing the space required for the carrier attachment. 7

The upper carriershaft a, is mounted in sleeves in rack bars a, sliding in suitable guide-ways on the side boards 0, and adjusted by toothed segments 0 on a shaft a for regulating the tension of the carrier drive chains, pawls engaging teeth on the rack bars a for holding them at the desired adjustment. This arrangement is substantially the same as in my former patent, referred to, except that the toothed segment a has a polygonal hub to receive a wrench for effecting the adjustment referred to.

The carrier bottom board 0 has a semicylindrical guard 10, (see Figs. 5 and 5) secured to its lower or receiving end, extending from side to side between the sprocket Wheels of the carrier and around in front of and under the shaft B, concentric therewith and with the flange 7. It has a groove or double flange at its upper edge, through which it is bolted to the bottom board and end flanges bearing on the shaft B for further supporting it, said guard serving to prevent the material from catching on the lower edge of the bottom board and so obstructing the operation of the carrier. It also serves to support the carrier buckets as they pass under the shaft B.

The manner of attaching the flights E to the carrier chains is shown in Figs. 4 and 4 The chain links e to which the buckets are to be attached have laterally projecting arms 6' forming saddles provided with upturned parallel lips or cars 6 6 between which the lower edges of the buckets E fit snugly, being secured in place by through bolts or rivets e. To the outer edge of the bucket,a grooved or flanged cap e is secured by a bolt e, which passes through the bucket E edgewise and through a perforation in the base e of the saddle. The bolts a secure the caps e and buckets E to the saddle and prevent the splitting of the flights at the bolts or rivets e. The ends of the buckets overhang the drive chain links but are cut away at e, adjacent thereto, to allow them to pass the sprocket wheel guards or curved flanges 7. The lips or flanges 6 in connection with the rivets e permit the use of thin, high buckets, the rivets securing the flanges firmly and preventing the splitting of the flights near the chain. By this construction the flights can be made, not only much lighter than those heretofore in use,but they can also be made wider or higher, thereby increasing their carrying capacity, which is important in carriers delivering at a steep or sharp elevation.

The end 16 of the boot at which the buckets E enter, is made flaring, by rounding outward the edge of the sheet metal of which the concave bottom 9 is formed, or in other suitable manner, to facilitate the entrance of the flights and prevent them from coming in contact with said edge. 7

In Fig. 3, a modification in the construction of the boot is shown, the details thereof being shown in Figs. 3, 3 and 3. In this the boot is formed in two parts, the bowl portion, shown at 3 being provided with foot brackets 17, through which it is secured to the floor or other suitable support, and at 18 with hearing sockets in which are journaled the sleeves 6 on the side plates 0, which are secured to the carrier side boards 0'. These side plates are provided with the guards or flanges 7 converging and protecting .the sprocket wheels, as in theconstruction first described. In this construction, the bowl portion of the boot remains fixed when the angle of the carrier is adjusted as is found desirable under some 10- cations of the carrier.

In Figs. 10, 10 and 10, another modification of the form of the boot side plates is shown, adapting the boot to the form of the carrier shown in Fig. 10, in which the carrier buckets move in a reverse direction to that shown in the other figures and operate in a pendent position. In this, however, the plate has the curved guard or flange 7 covering the sprocket wheel, with a supplemental flange 19 extending in an arc of a circle between the two portions of the drive chain for further protecting the sprocketwheel. In this construction the carrier flooring is provided at its upper end with a discharge spout and the carrier frame is provided at its upper end with a hood G, which prevents the throwing offof material which, in the rapid movements of the carrier buckets might fail to be discharged at the spout g, and which, if carried around by the bucket, will drop back through the open chain carrier and so be returned to said spout. With the carrier thus arranged, the bevel gears d (1 will be set facing in an opposite direction to that shown in Fig. 6 causing them to drive the carrier in a reverse direction, as required.

In Fig. 2, the carrier is shown applied to carry straight away from the machine and in this the supporting brackets may be bolted directly to the machine, as shown, or they may be formed on the boot as shown in Fig. 3 and bolted to the floor orother support. In this arrangement the driving sprocket wheel instead of being on the counter shaft D, will be placed on the lower carrier shaft and directly connected by a drive chain with the driving sprocket wheel on the cutter cylinder shaft (or other suitable support) as indicated by the dotted lines in Fig. 2. 7

It is necessary for the discharge spout of the cutting machine and all hopper boards to stand as nearly perpendicular as is practicable for the reason that all material cut green for ensilage, such as corn stalks and ears, sorghum, sugar cane, alfalfa, clover, &c., is so gummy and sticky as to adhere to the discharge spout of the cutter and to the carrier hoppers, if the surfaces are not almost perpendicular. The same is the case with cured cornstalks, leaves, hay and clover when wet with snow or rain, and for this difficulty as well as to secure steep elevation, the low down boot or pocket is desirable. Furthermore, there is a serious difficulty to be overcome by reason of this same wet and sticky cut material adhering to the chain and becoming packed between the teeth of the sprocket wheels, which eventually increases in quantity until the chain slips off the sprocket on one side, permitting the buckets to stand diagonallyinstead of square across the carrier, producing immediate breaking of the links of the chain.

The advantages of the construction described in overcoming thedifficulties referred to, will be apparent. The carrier attachment is rendered more compact than under previous constructions, thereby adapting it to the narrowest or most confined places in which the cutting machine itself can be accommodated; the boot or receptacle for the cut material, with its folding hopper can be readily adapted to any angle to which the carrier is adjusted,

and the material being deposited therein in front of'the receiving end of the carrier, the I latter can be made to deliver therefrom in a direction more nearly vertical than under the former constructions referred to, in the latter case relieving sagin the inoperative or return portion of the drive chains.
