NATHANIEL SHAFFSTALL, OF FLINT, INDIANA.

PLOW.

SPECIFICATION forming part of Letters Patent No. 254,394, dated February 28, 1882.

Application filed December 7, 1881. (No inodel.)

To all whom it may concern Beitknown that I, NATHANIEL SHAFFsTALL,'

a citizen of the United States of America, residing at Flint, in the county of Steuben and State of Indiana, have invented certain new and useful Improvements in Plows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will -enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to plows; and it consists in the construction and arrangement of the several parts, as will be hereinafter fully set forth.

In the drawings, Figure lis a side elevation; Fig.2, a sectional view of the frame-work with the plow attached thereto; Fig. 3, a top plan View, and Figs. 4, 5, and 6 are details. Fig. 7 is a vertical longitudinal section, looking from the left side of the plow.

AA are the wheels. The spindles are formed upon the lower ends of the vertical slotted axleplates a a, as shown.

The axle-frame consists ot' the horizontal cross-plate b,.which has its ends bent downwardly, forming the angle-plates b', the lower ends of which are slotted and are secured to the slotted plates a a by suitable bolts, and is capable of being set at different heights upon 4 them, as shown.

Attached to the upper horizontal sides of the angle-plates b is the frame C. Its forward end extends in front of the axle-frame and affords means of attachment for the tonguehounds. The right frame-bar C extends backwardly from the frame b. Its rear endis curved downwardly, and has pivoted to it the small wheel D, as shown. The left frame-bar C extends backwardly to the point where the right rod commences to curve, where it is bent upwardly and carried across to the right framebar and secured to its sides, as shown.'

Extending from the point where the left l frame-rod C bends upward to the lower end of V The chain ghas one end secured to the bottom of this lever, is carried around the grooved pulley e, and is attached to the lever above the pivot-point, as shown. To prevent slipping the cha-in is made fast to the pulley bya pin, as shown.

Secured to the rear end of the plow is the chain g', which passes over a pulley, g2, on the right frame-rod C, and is attached by a hook upon its end to a ring in the lower end of the lever G, as shown. By this arrangement of the chains and lever the point of the plow can be raised or lowered, or it can be raised entirely out of the ground. When the plow is in the ground and at work the chain g is unhooked from the lever G and caught over the top of the frame-work. The plow can then be ranged at different depths by the lever Gr. When it is desired to raise the plow entirely out of the groundthe chain `g is hooked to the lever G, which is then carried backward, and the front and rear of the plow are elevated together.

Placed around the crank E, between the pulley c and the side of the arch b, is a ratchetwheel, c2, the teeth of which engage with a projection upon the end of the lever c3, which is pivoted at e4 to the top of the frame G, as shown. The foot-rest e5 extends beyond the pivotal point, and the downward projection e permits the lever kto rise sufficiently to clear the ratchetteeth. The lever falls into position by its own weight, or a springmay be placed under its rear end. The forward ends of the frame-rods C are curved slightly upward, and form a loop in their ends, as shown.

H H are hounds. They have loops upon their inner ends, through which and the loops in the forward end of the frame C passes the rod h. A crossbar, h', extends across the inner ends of the hounds to brace them.

I is the tongue. It is pivoted, as shown, to the forward end of the hounds, and its inner end extends backward to the bar h', and has formed in its inner end a vertical slot, i, as shown. Pivoted centrally to the bar h is the L-shaped lever i. Its forward arm extends overthe tongue and its end is bentdownwardly into the slot z', as shown. The other arm extends along the har h', its end projecting be- 50nd the hounds, and has pivoted to it the connecting-rod i2, the other end being pivoted to the lever K, which is pivoted to the left frame-bar C, and ranges along a curved rack, k,which is secured to the top ofthe frame-bar, as shown. In the operation of the plow it will be seen that by fixing the lever K at different points along the rack 7c the inner end of the tongue can be swung to the right or left, as de- Sired, thus regulating the width of the furrow at will.

1. The combinatio'min a sulky-plow, of the arched frame I), the crank E,journaled therein7 the grooved pulley e, the bar e,connecting the crank to the front end of the plow-beam, and the lever G,provided with a chain, g, substan tially as shown and described.

2. In a plow, the combnation,with theframe and plow-beam ofthe connecting-bar and cra-nk E e e and the lever G, having its chain g, attached to its lower end, passed around pulley e and secured to the lever above its fulcrum, and also provided with chain g', attached to the rear end of the plow and vpassing over pulley g2,substantiallyas and for the purposes shown and described.

3. The combination of the plow-beam, its vertical bar e', the crank E, and its pulley e, with the lever Gr, chain g, adapted to operate the forward end ofthe plow, and the chain g', passing over the pulley g2 and adapted to operate the rear end of the plow, substantially as shown and described.

In testimony whereof I ax my signature in presence of two witnesses.

NATHANIEL SHAFFSTALL.
