IMPROVEMENT IN HAY-SPREADERS.

To all whom it may concern Be it known that I, WILLIAM H. H. FRYE, of North Fryeburg, in the county of Oxford and State of Maine, have invented a new and valuable Improvein Hay-Tedders; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1, of the drawings, is a representation of a central vert-ical'section of my invention.

Figure 2 is a top view of the same.

Figure 3 is a rear view.

l,My invention relates to hay-tedders; and consists in the construction and novel arrangement of devices, whereby the forks are operated in a simple but etlicient manner.

lhe letter A, of the drawings, designates the frame of the sulky, provided with the shaft B, and supported upon the wheels C, to each of which is attached an inner toothed wheel'.

D'represents the, tilting frame, which carries the forks. It is pivoted to the frame A, and locked thereto by the spring foot-latch a, when in operation.

The standards b, which support the crank-shafts c, to which the forks are attached, are secured to the rear portion of the frame D.

At the feet of these staudardsand secured to the beams of the tilting-frame, are the slotted plates E, through which the fork-shafts play. v

F designates the operating pinions, engaging with the teeth of the wheels C, and rigidly fastened to the crank-shafts e. These crank-shafts are attached to the standards b by means of half-boxes, andthe ends of the fork-shafts are attached tothe cranks by a similar means. The cranks are so arranged with respect to each other, that the forks attached thereto will descend at 4different times.V The number of forks is not limited. In the drawings, four have been shown as being operated by each wheel, making eight in all, the crank-levers being arranged at right angles adapted to operate upon uneven ground without being' liable to injury. Thisis accomplished by pivoting the prongs to the shaft, in suoli a manneras to give them the power of folding to the rear, when necessity requires.

For thecheaper grade of machines', a simple slot is all that is required in the plate E, t-o provide a fnlcrum for the fork-shaft The best machines, however, will be provided with anti-friction rollers, nI n, between which the fork-shaft will play, as shown, in connection with the extreme left-hand fork, in thegview illustrated by iig. 2 of the drawings.

By arranging the fulcrnni-plate'E of the tiltingframe between the prongs of the forks and the crankshaft, I am enabled to employ a pinion, engaging im mediately with' the gearing 'of the wheel C, and, at the same time, to gain great power.

iVhat I claim as my invention, and desire to secure by Letters Patent, is- The arrangement of the tilting-frame D, toothed stop a, geared wheel O, pinion F, fuIcruni-plate E, crank-shaft e, and nprights b, when constructed as and for the purposes set forth.

In testimony that I claim the above, I have hereunto subscribed my name in the presence of two witnesses.'
