IMPROVEMENT IN SULKY-PLOWS.

Specification forming part of Letters Patent No. 210,867, dated December 17, 1878 application filed April 16, 1878.

To all whom it may concern:

Be it known that I, IVILLI AM IV. MARSH, of Sycamore, De Kalb county, State of Illinois, have invented new and useful Improvements in Sulky-Plows, of which the following is afull description, reference being had to the accompanying drawings, in which- Figure l is a top or plan view; Fig. 2, a side elevation, with one of the wheels removed Fig. 3, a longitudinal section enlarged; Fig. 4, a rear view enlarged; Figs. 5, 6, 7, and 8, enlarged details of the plow-sumiorting devices; Fig. 9, a rear elevation of the frame or axle enlarged; Fig. 10, a top or plan view of the same; Figs. ll, 12, and 13, enlarged details of the spindle and head for the land-wheel and the raising and lowering devices.

The nature of my invention consists in the construction of the frame or axle, the reversible sliding head carrying the land-wheel spindle, and provided with pins for connection with the operating devices adapting said spindle to be reversed when worn, and in the construction of the plow-beam support, pivoted to the bail and having projections forming spaces between them to receive the beam, all as hereinafter more fully set forth, and pointed out in the claims.

The wheels A A may be of any of the ordinary forms of construction for wheels of sulky or gang plows, A being the land-wheel and A the furrow-wheel. I

The axle or frame is made from a single piece, and may be cast, or otherwise suitably formed, so as to have a horizontal portion, B, and vertical portions B B, B being the landside and B the furrow side of the machine. The portion B is provided with a head, V, cast or formed therewith, which head is pro vided with flanges or guides 71' c" on,its sides, which fit corresponding grooves h formed in the head W, so that the head IV can slide up and down on the head V. The head "W earries the spindle for the land wheel, which spindle, as shown, is cast or formed with the head, but may be formed separate, and be permanently secured thereto. At each end of this head W is a pin, c, so arranged that the operating-lever can be connected therewith. A pin at each end is necessary in order to enable the head to be reversed and the proper connections to be made with the operatinglever. At the center of this head IV is a projection, g, against which the inner end of the hub of the land -wheel strikes when in use, so as to form a bearing therefor, and from this shoulder g the spindle I)v projects. To the upper pin, 0, of thehead .W is attach one end of the link or bar X, the other enu'ol; vhichis connected with the end of the lever Y by means of the bolt or pivot 01. The'lever Y is pivoted to a suitable ear formed on the head V by means of the pivot or bolt to, which bolt also acts to hold the rack Z in place. lower end of this lever is turned or bent at right angles to the main portion, and to this portion b is connected the upper end of the strap or link X. 4

The upper end of the lever Y extends up to I be within easy reach of the operator when on his seat, and is provided at its upper end with a bell-crank lever, 1 suitably pivoted thereto, to which lever '12 is secured the upper end of the rod w, which extends down by the side of the lever Y, and is provided at its lower end with a suitable pawl or point, y, which slides up and down in, and is held in place by, a guide, 00, formed with or secured to the lever Y, just above the rack Z. The rack Z is of a segmental form, and is secured in any suitable manner to the upper end of the head V, as shown. The head V is provided with a shoulder and a suitable ear, j, to which the rack is secured by means of a bolt and the bolt or pivota. The rack Z is provided with suitable notches z, with which the pawl or point y engages, to hold the lever Y in any desired position.

By attaching the spindle D to or forming it with the sliding head V, and constructing this head so that it will have clevises at both ends for attaching it to or connecting it with the operating-lever or mechanism, it will be seen that when the axle becomes worn on the under side, as it is liable to in use, the head W can be taken off from its supporting-head V, and changed end for end, so as to bring the lower side of the spindle D on the upper side, and the upper side on the lower side, thereby bringing the lower side, which has not been worn, into position to receive the wear, so that double the wear can be had from the same spindle, as it is evident that both the upper and lower sides can be worn to an extent as far as practicable before the spindle becomes useless, and by providing the plate E, having the cap or cover f, it strengthens the support or head W to some extent, and also furnishes a means to prevent dust, grit, and dirt from working in at the top of the spindle by reason of the cap f extending over The plate E may the inner end of the hub. be of light cast metal, or of other suitable material strong enough for the purpose required of it.

In use, if the operator desires to change the I position of the frame relative to the 1-. nd-wheel, he can do so by taking hold of the lever Y, and, through the lever 41 and rod w, disengagin gthe pawl y from the notch z, with which it is engaged, and moving the lever Y forward or back, which movements of the lever Y will The raise or lower the land end of the frame by reason of the head V sliding on the head W. When the desired position is reached, the lever can be held in such position by causing the pawl y to engage again with the notch 2, which will retain the land end of the frame in that position.

In the horizontal portion B of. the frame, on the furrow side thereof, is formed a shoulder or recess, the lower portion of which projects some distance each side of the frame, and is provided with openings for the passage of bolts, so as to secure the inner end of the bar or support E firmly in position on the shoulder. This bar or support E projects some distance forward of the frame and at its side, and suitably secured thereto is a second bar or support, F, which is shorter than the bar or'support E, and does not extend back to the frame B. These bars E F, if desired, may be made from a single piece. These bars or supports E F are to be provided with suitable holes a, for the passage of bolts, so that the tongue can be secured thereto. Two sets of holes are shown, so as to enable the tongue to be secured in two different positions, corresponding with the positions of the plow when in use; but more sets of holes a may be provided if deemed necessary.

The brace G is rigidly secured at one end to the ton gue-support E F, and its other end is secured in any suitable manner to the vertical portion B of the frame. To the rear of the ton guesupport F is also secured one end or side of the brace or support I, which passes down and around the brace G, and is so formed as to fur nish a proper support, to which the foot support or plate J is secured by means of bolts. The plate J is provided with an ear or flange, g, by means of which it can be secured to the brace G, thereby giving the support J additional strength and firmness. At the center of the forward edge of this support J is a hook, I), over which a link of the chain K may be slipped, which chain K may be of any suitable construction that will enable it to be secured in place. The lower link of this chain K is secured, by means of the wooden pin 0, to the end or head of the bolt or center pin d, which secures the clip L to the doubletree M.

The clip L may be of any suitable construction to enable it to be secured to the doubletree at its forward end and to the. end of the plow-beam at its rear end.

As shown, the plow-beam is provided with a clevis, between the parts of which the end of the clip or clevis L passes, and in which it is held by the bolt f, the clevis on the end of the plow-beam being provided with a series of holes, c,for the bolt, so as to enable the proper adjustment of the clevis L for the required depth of plowing.

By this arrangement it will be seen that the chain will form an efficient and reliable means for supporting both -the whiffletrees and end of the beam, and keeping the same from dropping upon the ground or under the horses heels when the plow is being moved backward or forward out of the ground, durin g which movements there will be no tension or draft to keep these parts from falling, as aforesaid, unless kept up or supported in some manner; and by attaching the chain K by means of a wooden pin, a, it will be seen that in case of great strain the pin will break and the chain will become detached from its connection, so that no damage can be done by reason of such strain.

The seat- H may be of any suitable construction, and, as shown, is mounted on the spring H, the end of which spring is secured by means of a bolt to the horizontal portion of the frame, an opening, It, being provided to receive the end of the spring to prevent the seat from turning.

The plow-beam N is of the usual construe tion, and the plow 0 is secured thereto as usual, the plow being of any of the well-known forms. This plow-beam is supported upon a plate, P, which plate is provided with projections 1 so arranged at the front and rearsides as to leave a space, 3', between them of a size corresponding to the width of the plow-beam. At the rear end of this plate P, and projecting downward on each corner, is an ear, a, each car being provided with an openin The plow is secured to the plate by means of the bolts or yoke l, which passes up through suitable openings ll: in the plate P on each side of the plowbeam and the bar or plate m, which passes over the top of the beam, and is held in place by means of nuts on the ends of the bolts or yoke I, so that by reason of the plowbeam being secured in the notches j at the front and rear of the plate, and locked therein by the plate or and yoke Z, all side motion is prevented, and the plow and beam will be held securely in position. Only two openings, j, are shown 5 but more may be used. if desired.

The holes 1; in the plate are so arranged that the center hole will he in position for the bolt to pass one side of the beam, no matter in which of the notches j it may be placed. This plate 1? is pivoted to the frame Q by means of the rod 0, which passes through the frame and through the ears or, so that the plate P is free to turn up and down on its pivot or bolt 0. The frame Q is pivoted at one end to the stud or pin k, formed with or secured in the vertical portion 13 of the frame. The other end of this frame Q, is pivoted on that portion of the spindle G which passes through the opening 0, so that the frame can be raised and lowered, carrying with it the plow. The end of the frame Q which is secured to thespindlc O is provided with a crank, It, to the upper end of which is connected one end of the link or bar S, the other end of which is attached to the lever T, which lever is pivoted by the bolt or pivot p to the ton gue-support E. The lever T extends up to within easy reach of the operator, and at its uppenf"? A provided with a bell-crank lever, q, pivoted to the lever T, to which lever q is attached the upper end of the rod 9', which rod extends down by the side of the lever, and at its lower end is provided with a pawl or the end of the rod itself may be so formed as to act as a pawl to engage with the notches a in the rack U, which rack is secured in any suitable manner to the tonguesupport E.

In use, the plow can be set or secured in the desired notch j to cuta wide or narrow furrow, and be held in place by means of the plate and bolts; and the plate P is to be pivoted to the frame Q, so that it can turn on its pivot, which enables the point of the plow to adapt itself to the inequalities of the ground.

When it is desired to raise the plow for any purpose, the operator, by taking hold of the lever T and moving it back, can raise the frame Q, and with it the plow, and by moving it forward he can adjust the plow so as to cut any desired depth.

The portion 13" is provided with an opening, 0, to enable the crank It to operate directly beneath the frame, and this portion B of the frame is so formed as to have a portion thereof on each side of the opening G, and is provided with suitable openings for the pas sage of the spindle C, so that the spindle will have a firm support, and so that its position can be changed when the under side becomes worn, so as to bring the upper side into position for wear. This spindle is held in place by means of the pin a, and the inside of the inner portion of the part B is provided with a projection, m, to give a stronger support and a longer bearing to the inner end of the spindle for strength and steadiness. The outer portion of the part B" is provided with a cap, Z, so arranged as to project over the end of the hub, to prevent dust, dirt, and grit from getting in on the spindle.

The spindle O is secured in place by means of the pin 0, and when it is desired to turn the spindle over the pin can be removed and the spindle turned and the pin driven in again.
