To ALL wHoM IT MAY ooNoERN:

Be it known that I, A. B.v SPRoUT, of Hughesville, in the county of Lycoming, andiState of Pennsylvania, have invented a. new and useful Improvement 'in Hay-Elevators; and I do hereby declarethe following to be a full and 'exact description thereof` reference being had' to the accompanying drawing, and to the letters of referncemarked thereon.r i

My invention consists in an i'mp State'swlere granted to ine on the 1st dayl of May, 1866, and numbered 54,431.v

The'nature of my invention, as herein described, consists in horse hay-fork with a cutting-edge or edges, be operated yso as to catch and hold in the hay fo of discharging it from the fork.

To' enable others skilled'in the art to maire and use myinvention, In the accompanying ldrawing which forms part of this specification- Figure 1 represents a side 'elevation of my improved hay-elevator. Figure 2'reprcsents an edge view of the same. l In the drawings, andB represent two fiat bars of iron or steel, or steel andiron lcombined. Said hars are bentinto the form represented in figs. lend 2,`and are hinged or pivoted at the point marked x. The upper end ofthe bar B is provided with a ring or loop, it, and pulley, e. To the zipper en d of the bar A is pivoted, at the point marked a baror lever, D, which is pivotedto a'bar or lever, C, at the point marked 2, which bar Ior lever C is pivoted to the lbar B at the pointmarked .1. To the part 4 ofthe bar or lever C is attached a cord orv rope, z', whichpasses up over thc pulley e. To the ring or loop It is attached the hoisting-rope J. The lower ends of the bars A and B are provided with coniform points markedfand g, which points are furnished with shoulders or hooks Sand 7. The inner sidel of the coniform-points fand g are flat, and in grinding are made' slightly concave, so that they fit together,'and the outside'of said points is bevelled oif to asharp edge. The

edges of the pointf project slightllypast the edges of the point g for the purpose of forming a keen cuttingedge i to the point.

` The operation of my improvement is as follows for cutting its way into the hay, and fio-constructed that'it can r' elevating it, and then released'from the hay ,for the purpose I will proceed to describe its construction.

When'I desire to cut out part ofthe stack or mow of hay, I open nt thepoints, as indicated by the. dotted lines in fig. 1, 'anl'when thus opened out, I force the points downinto the hay, and they will cut, at each thrust of the fork or elevator, a gap equal in length to the distance between the outer edges ofthe pointsfand g, land the depth ofthe cut will be equal to the'distance it is forced down" into the hay when the desired part of the stack or mow is out out. I then'close up the fork or elevator, as shown in figs;.1 and 2. I then, by pressing down on the ring k and the part marked 5, force the fork or elevator down into the centre ofthe mass of hay which has been cut loose. I`then press down on the part 4 of the' har-lever C, which will spread out the`bars A and B at the upper end, which-spreading of the bars will open out or spread vthe pointsf and g and cause the shoulders or hooks 6 and 7 to catch in the hay, takingcare to Vspread the bars A and B until the pivot-joint 2 drops -belowthe line marked m. I then hoist the hay by drawing on rope J'. until it'is elevated to the desired place: I then draw on cord z', which will draw up the'bars. -or levers C'and D, which will bring the upper ends ofthe barsA and B together and close the points-f and g, which closing of the points will allow the hayY to drop-ofl` the fork or elevator. By use of cutting-edges on the v 'pointsf and g, and so arranging them that when they are closed up they will form a single point provided with a. cutting-edge, the forliI or elevator can with greater ease-be forced into the hay, for the point cuts the way for the fork or elevator, and thereby greatly lessons the'labor of forcing the fork or elevator into the hay. Having thus described th nature, construction, and operation' of my improvement, what Iolaim as of my invention, is f 1. Providing the extreme.penetratingpoint or points of a horse hay-fork with a cutting-edge or edges for cutting its way into the hay, said points beingso constructed that they can bel operated so asvto catchvand hold the hay for elevating it, and be released at willfrorn the hay for discharging it. 2. The coniform pointsf and g, provided with cutting-edges, and shoulders or hooks 6 and 7, constructed,

urpose set forth;

arranged,'and operating substantiallyl as herein described, and for the p,
