TO ALL WHOM IT MAY OONCERN i Be it known that I, WILLIAM H. ELLIOT, of the City, county, and State of New York, have invented a new and improved InIay-Loaderg and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanyinfr drawings, and to the letters of reference marked thereon.

Similar letters of reference indicate the same devices in all the igures.

To enable others skilled in the arts to comprehend, make, and use my invention, I will proceed to describe its nature, construction, and operation.

The nature of my invention consists in the employment of certain devices for lengthening and shortening the cord between the end t`- the crane and the fork of an Elliothay-loader, so as to reach the hay at a greater distance from the hay-rack than can otherwise be done. l

Figure I'is an elevation 0f the upper portion oi' an Elliot'hay-loader, showing the head of the arm in section,

lforkp being 'a par-t of the same ligure.

Figure 2 is a plan of the end of the arm, with the connecting-rod, arm., and pawl removed.

Figure 3 is an elevation of the arm and pawl.

a, standards of the crane which stands upon the hay-racl:; at', ratchet upon the top of the standard; Z), spindle upon which the arm turns in the standard; c, head of the arm which supports the devices for adjusting the cord; (Z, wooden connection between the spindleand head of the arm; e, bolt which locks the arm in any required position; j', pulley which winds up adjustable cord l; t', pulley around which cord c is wound when f' adjustable cord Z is drawn out; g, movable arm which supports paivl t this arm is placed. between the two pulleys and has a 'motion around the same centre; 7c, spring which winds' up adjustable cord Z; m, brace of the arm; o, notch on pulley j'; p, fork e, lspring which' pushes bolt e out of the notches on ratchet a, and by means of rod n holds arnlg in a vertical position. Any weight thrown uponcordt turns the pulley f upon its axis, which carries with it pawl Zt and g, and rod n, drawing bolt e into the notches on ratchet a', and by these means locks the arm. When cord Zhangs in a vertical-position, it allows pawl ZL to catch notch o on pulleyf, which prevents it from being unwound while in this position, but when cord Zis carried out to the position represented by dotted lines o, as it must be to reach hay at some distance from the cart, the pawl Zt (which always rests against the cord Z) is carried out with the cord so as to release pulleyf, which allows the cord to unwind to any required distance, but it is at once wound up again by the power of spring Ze as soon as set at liberty. Pulleys andf are attached together. and arin g is supported upon a hub between them.

The operation of my improved hay-loader is as follows z As thc pitcher proceeds towards a cock or" hay for thc purpose oi' pitching it upon the hay-rack, the arm of the crane swings around lightly in the same direc ion. It the cock of hay stand nenrthe` hay rack, the Afork is inserted int-o it; then Aby depressing the handle the whole weight of the hay is thrown upon cord Z; this locks the arm of the crane in its position so that it cannot swing around, the cord being of suiiicient length so thatwhen the fork is brought to a horizontal position the hay is held up clear of vthe ground. Now, by pushing upon the fork thc hay is caused to swing up to the top ot' the load with very little effort on thepnrt oi` the pitcher. But it is not always possible to drive near enough to a cock of hay to reach it with the ordinary loader, and it is for the purpose of meet-ing such difficulties that I have invented my improved hay-loader. As the pitcher goes towards 'amore distant cock of hay, the arm first swings around in that direction, the lower end of thc cord is then carried out, as shown by dotted lines r, which raises pawl ZL, and releases cord Z, so that it runs olf any required length the fork is then inserted into the cock, which is drawn by means ci' the fork to a position near the hayracl As the hay is drawn near the rack, the spring/c, actingl upon pulleys and j', causes the cord to be wound up again, when pawl t catches the pulley and fastens the cord; the hay is now raised to the top of the load as before described. In lny improved hay-loader both bolt e and pawl Zt are operated by cord Z, bolt e being` operated by the weight on the cord, and pawl ZL by the position ot' the cord.

Having described my invention, what I desire to have secured to me by Letters Patent ofthe United States, isi 1. The employment of 'an adjustable cord l, between the arm' of the crane and the fork p, substantially as herein shown.

2. The employment of pulleysf and z', in combination with spring k and cord Z, for the purpose of taking uptbe latter after it has been drawn out, substantially as specified.

3. Connecting together pawl h and bolt e, so that any motion given tothe former will move the latter, substantiallyias and for the purpose specified. l

4. So combining pawl t and bolt e with cord Z, that tlie latter shall operate the two former, substantially y as set forth.

5. Pivoting pawl L to movable arm g, so that these devices may have a little motion around the centre of the pulleys, substantially as herein shown.

Will. Il. ELLIOT.
