To ALL WHOM IT 'MAY ooncnnm Bc it known that I, WILLIAM H. ELLIOT, of the icity, county, and State ofiNew York, have invented a new and improved Machine for Loading -Hay and I do hereby declare thatthe following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.-

Similar letters of reference indicate the same devices llf all the figures.

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

The nature of my invention consists in the employment of friction as a means of communicating power in combination with a crane and fork, for the purpose of loading hay from the field on to the cart or hay-rack, and by suitable automatic machinery so applying the friction that when the fork is loaded it will be carried up to a proper height, held .there suspended by friction until the hay has been discharged, and then allowed to fall gently to the ground. It also consists in the employment of elevating devices which are propelled bythewheels of the cart, in combination with a fork which is so constructed as to trip and discharge the hay.

Figure 1 is an elevation of a portion ofa hay-rack or cart showing my improved loading devices.

Figure 2 is an elevation of a portion of the opposite side of the same, showing the gearing with the wheel removed.

Figure 3 115.5. modificatiornof the same mvention, showing the-use offriction cones instead of belts for pro dncing the necessary friction.

Figure .4 is a plan of the fork, with a portion of the head and handle broken away.

a, hay-rack, upon which stands 6, the standard of the crane, bolted to the bed-piece 6, which in its turn is bolted to the hay-rack. This standard is tapering, .tubular, and composed ofboiler-plate. e, arm of the crane. c, casting making a part of the arm, and having upon it thc joint 1:", pawl, pulley, 82c. d, head of the crane, with a tubular portion projecting down into the standard, upon which it turns as upon a pivot. To this head the arm is pivotedat c. a, gear which is attached to or has a bearing around the hub of a rear wheel. This gear meshes into pinion c, whielris upon the shaft 0, with pulleyf. g, swinging frame, which swings upon its joint at g, and supports-pulley 7L and rope cylinder 2' on the same shaft. k, belt-connecting pulleyfwi'th pulley h. l, tightening pulley attached to the hay-rack, against which belt 70 is tightened when the frame 9 is raised by the lifting rope m. n, rod standing upon frame g. This rod has a ring, 91., upon its-upper end, through which the lifting rope in passes. m, an enlargement on the lifting rope which will not pass through the ring at. The lifting rope is attached to the cylinder 2', passes up through the standard and head cl, over the'pulleys 0 o o, and then down' to the fork. 1;, head of the fork 11, tines; q, joint which allows the tines to turn downer trip to discharge the hay. This joint is made loose enough so that the catch 9' may have-suiiicient lateral motion to disengage it from the head 12. s, lever by which the handle is rolled to disengage catch 1', so as to dump the hay. :0, arms on gear a, which are lashed to the spokes of the wheel.. 10, 'axle. a:, casting which supports the drivinggear c, and the other elevating devices of the modified invention, shown in fig. 2. g, arm swinging upon the shaft with the rope cylinder 1', and supporting tightening pulley Z. k, friction cones, shown by dotted lines, the hollow cone making a part of the rope cylinder 1', which is loose upon the shaft, while the inner half of the .friction cone is attached permanently to the shaft. a, sleeve projecting from the box or hearing of the shaft. u, sleeve making a part of arm g". These sleeves are so shaped that when the arm 9 is raised by the lifting rope acting upon tightening pulley Z, it slides longitudinally upon the shaft 0, crowding the two halves of the friction cone together, thus producing the necessary friction for winding up the lifting rope.

The operation of my improved hay-loader is as follows: .As the team passes a cock of hay the fork is thrust into it, and as soon as the motion of the team tightens the rope, the frame g israiscd, bringing belt k against the tightening pulley, when the rope-cylinder immediately begins to turn, drawing the fork with its lead of hay nearly up to the end of the arm. When the cnlargementm reaches theringn it depresses frame g, and loosens the belt so that it slips but holds the hay suspended. The hay may'now be swung over the load; then, by turning the fork handle by means of lever a, the. catch 7* is disengaged, thc'tines drop down, and the hay is discharged.

' its hendle and pressing against the same.

The fork is new swung away from over the loud and drawn down to the ground, there not being friction enough produced by the weight of the fork alone to keep it 'up.

. Havingdescribcd my invention, what I desire to have secured to me by Letters Patent of the United States, is V h 1 The combination of the, swingingframeg or its equivalents, a lifting rope m, and en elevating fork, so

arranged that the loaded fork will operate the frame to produce the necessary friction to raise the lead, while said frame trill drop and the elevating mechanism cease to act when the fork is unloaded.

2. The combination of the lifting rope m, swinging frame 9, pulley h, belt 7:, and tightening pulley 1', arranged and operating substantially as described.

3; The step 111/ upon the rope m, in combination with ring 1;, and swinging'frame g, for the purpose of decreasing the friction at the proper moment, so :is toheld the fork suspended, as set forth.

4. Constructing a tripping fork so that it prey be released for the discharge of the load by simply turning 5. The combination of the spring-catch 1', head 2, and handle of the fork, suhstantially as and for the purpose set forth.
