FODDER- CARRIER.

SPEGIFICATION forming part of Letters Patent No. 448,857, dated March 24, 1891.

Application filed June 13, 1890. Serial No. 355,379. (No model.)

To all whom it may concern:

Be it known that I, WILLIAMSON R. HAR- RIsoN, a citizen of the United States, and a resident of Canton, county of Stark, State of Ohio, have invented a new and useful Improvement in Fodder-Carriers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making a part of this specification.

My invention relates to improvements in carriers for fodder-cutters; and it consists in certain features of construction and combination of parts, as will be hereinafter described, and pointed out in the claims.

Figure 1 of the accompanying drawings is a perspective of a fodder cutter and carrier, illustrating my'invention, with carrier set to carry the cut fodder to one side of the cutter. Fig. 2 is a similar view of detail comprising the parts of chain-tightener at the top of carrier. Fig. 3 is a side elevation of fodder cutter and carrier, showing the carrier attached to convey the cut fodder out in front of the cutter. Fig. 4c is a perspective of the hinge-plates, chain-roller, and hinge-pin; Fig. 5, a side view of the hinged portion of the two sections of the carrier.

The prime object of myinvention is to provide a carrier that may be attached to the cutter so as to deliver the cut fodder at different points and be driven by a sprocket at the bottom portion of the carrier. The carrieris composed of two portions-ahorizontal portion A and an elevating portion B. The parts A and B are secured together by the hinge-plates O D. The plate 0 is provided with a flange or plate portion a, by which it is secured to the side board a, a circular flange a forming a circular recess a having a central boss a and a shoulder a, the hinge-plate D having a side portion a, by which it is secured to the side board cf, the end of the board resting against the shoulder a, and a circular flange (0, adapted to pass into and turn in the recess a and an aperture a to embrace the boss a about which the plate D is rotated. To secure the parts together, the bolt 1) is passed through the roller E, plates 0 and D, washer b, and Secured by a threaded nut 19 thus forming a very strong, light, and accurately-working hinge and a support for the-chain-roller E. The hinge-plate D is provided with a downwardly-projected arm b at the lower end of which is secured a sprocket-roller F, as shown in Fig. 3.

At the upper end portion of the elevator 13 is provided a plate G, having an elongated aperture b, about which is placed outwardlyprojected flanges b to form a support for the journal-box H, said box having a tooth-rack I) projected therefrom to engage a pinion J, having corresponding teeth I) about on half of its periphery, and about the remaining half ratchet-teeth-b that engage a pawl Z2 These parts are. shown apart in Fig. 2 and assembled in Fig. 1.

To tighten the chain a wrench is placed on the hub Z) to turn the pinion to move the box H. The parts are used in duplicate, the pinion J mounted on a cross-shaft.

At the outer end of the horizontal portion A of the carrier is provided a cross-shaft K, having mounted thereon driving-chain rollers d, sprocket (Z,-and a bevel gear-wheel (2 On the end and side portion of the carrier-frame is placed a cast-metal plate L, having a journal-box portion d for the support of the shaft K and an ou:wardly-projected arm d, having at its end a journal-box (1 in which is supported a driving-shaft clflhaving mounted on one of its ends a bevel-wheel d to engage the wheel 61 and on the other end of said shaft is mounted a sprocket-wheel (i that has a chain engagement with a similar wheel mounted on a shaft supported on the frame of the fodder-cutter. To reverse the direction of the carrier, the parts mentioned and described as d, (Z (Z and (1 may be transposed or placed on the other side of the carrier A, the chain (1 placed about the sprocket 705. At the other end of the carrier is provided a cross-shaft 71 on which is placed in the track of the carrier-chain 71 small sprocketwheels Won the inside of the sprocket-wheels h. About the sprocket-wheels d and its is placed a driving-chain h, by which power is communicated to the shaft h, and sprockets 7L2, by which the carrier-chains h are driven. Then the carrier is placed as shown in Fig. 3, the chain 7L is removed from the sprocketwheels (1 and h and placed upon asprocketwheel 7L secured to the opposite end of the shaft h and is placed about the sprocketwheel if, mounted on a shaft 71 on the foddercu tter. lhe carrierwhile in this position obtalns its operating-power from the sprocket 71.", instead of from sprocket (Z which trans mits the power when the parts are in the position shown in Fig. 1. As shown in Fig. 3, I have located a portion of the carrier beneath the fodder-cutter to obtain compactness. I do not, however, limit myself to such location.

As heretofore constructed such carriers have been driven by a chain extending from a portion of the fodder-cutter to a suitable wheel or pulley at the outer end of the carrier, involving the cost of an additional chain as well as the maintenance thereof. Commendable efforts to drive the carrier by sprocket-wheels placed at the lower end of the carrier-frame have proved faulty, it not worthless, because of the slack of the chain allowing the chain to fall from the wheels. 'lo obviate this difficulty is the prime object of this invention, as it will be apparent that the natural operation of the parts herein before described will contribute to the desired end.

The carrierframe being. pivoted at h-a point at one side of the centerof the drivingshat't 7iasa n atu ral result when the outer end of the carrier is raised the chain will become tight and when lowered it will be so slack as to defeat the object of driving the elevator apron or slats, as the case may be To obviate this difiieulty,the arm 5 with its sprocketr.)ller F, is provided, which, when the eley'ator is raised, will swing out, as shown in Figs. 1, 3, and 5, to give out chain,and when the carrier is lowered the arm L and sprocket-roller F will be swung into the position shown in Fig. 5, the operation of which is to take up and pay out the slack of the carrier-chain h automatically to adapt the elevatonchain to be used to drive and at the same time to carry the'elevator slats or brackets.

Having thus fully described the nature and object of my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a fodder-carrier, the hinge-plates O and D, the former having the flange a recess a, central boss 0 and shoulder a and the latter having the flange a, perforation a and arm b the sprocket-wheel F, and rollerE, substantially as described, and for the purpose set forth.

2. In combination with the hinge portion of a two-part fodder-carrier, the cross-shaft h, having mounted thereon sprocket-wheels h and h, roller E, chain h, arm 0 and sprocketwheel F, by which the slack of the chain 71 may be taken up and let out as the outer end of the carrier is raised or lowered, substantiall y as described.

3. The combination, with the carrier, ot'the sprocket-wheel (i mounted on the shaft (1 placed at the side of the carrier, gear-wheel (1 mounted on said shaft d, shaft K, transverse to the length of the said carrier, which shaft has mounted thereon a gear-wheel d to engage the wheel (1 rollers d, and a sprocket-wheel d, a cross-shaft h, having sprockets 7L2 mounted thereon in terjacent its ends to engage the chain h, a sprocket-wheel hfimounted on the end of said shaft, a chain h" to engage the wheels (1 and h whereby power may be transmitted about the carrier-frame to a point between the ends of the carrier to engage the carrier-ehain h to drive the carrier, substantially as described, and for the purpose set forth.

In testimony whereof I have hereunto set my hand this 5th day of June, A. D. 1890.
