PLOW.

SPECIFICATION forming part of Letters Patent No. 422,418, dated March 4, 1890.

Application filed February 1, 1889. Serial No. 298,343. (No model.)

To aZZ whom it may concern.-

Be 1t known that I, JOHN W. JACKSON, a

citizen of the United States, residing at Ochlochnee, in the county of Thomas and State of Georgia, have invented a new and useful Improvement in Plows, of which the follow- 111;; is a specification.

My improvement provides a foot-bar for the shovels or shares pivoted to the bent end of the beam so as to swing adjustably'upon it from a vertical to an inclined position to suit different kinds of work and different kinds of plow plates or shares, and for this purpose the upper curved edge of the beam is notched and the upper end of the foot-bar is provided with a slot and a bolt adapted to be secured in the notches and to be raised in said slot free of them in swinging the foot over the curved edge. The handle brace-arms are made adjustable to suit the inclined adj ustment of the footbar, and for this purpose are secured at two points to the bent end of the beam. The plow shovel or'share is supported by a plate of novel construction, and I provide a landside adjustably connected to the bent end of the beam.

The preciseimprovementwhich I have made will be designated in the claims concluding this specification, in connection with the draw ings illustrating my said improvement The accompanying drawings illustrate my improved plow in perspective, in Figure 1 with the foot-bar set back upon the handle bracearms, and in Fig. 2 with the foot-bar in Vertical adj ustment; and Fig. 3 is a detail view of the device for supporting the plowshare, for securing and for adjusting it. Fig. at is a sectional detail of the device for securing the plowshare. Fig. 5 is a detail View of the same, and Fig. 6 is a detail of the foot adj ustment.

The plow-beam is formed of an iron bar curved down at its handle end a, so as to terminatein a short return end a, nearly parallel with the beam, and to the frontend of which the foot-bar or standard 0 is hung about the middle'of its length by a strong pivot bolt 1).

The foot-bar or standard 0 is made of strong strap-iron bent double, open at its upper end 0', and secured to the beam in frontof the brace-arms d, which support the handles in a manner which I shall presently describe. These brace-arms d (1 cross the bent end a a of the beain and are secured to it at two points 6 and f, and the handles 9 are secured to the upper ends of these brace-arms and to the beam. The upper edge of the plow-beam, over and above which the ends 0' of the footbar or standard 0 extend, forms an arc struck from the pivot 19 of the foot-barand has notches h, while the upper ends 0 of the foot-bar are provided with registering slots 11, through which a bolt j passes into the said notches and is fastened by a nut 70. This construction allows the foot-bar to be swung upon its pivot b, so as to set it to a greater or less inclination in relation to the beam to suit the work to be done and to fasten it by the bolt j in the notches h of the beam. For this purpose the slots t are made at one end z" to coincide with the notches of the beam and to rise therefrom in a slightly oblique direction to allow the bolt to be freed from its notch by moving it up into the oblique parts i of the slots, so as to carry it above the notched edge of the beam to permit the foot to be moved over the notches. The fastening-nut has a handle 7e, by which to screw and unscrew it, and the upper end of the foot-bar terminates in a handle 0', whereby to move it over the beam when the screwbolt is moved into the upper or oblique part of its slot. This construction permits the use of a foot-bar firmly supported at two points upon the beam and without intermediate or jointed connections and in a substantially vertical position, whereby it is adaptedto be used with shovel-plates or with scraper-plates, and is easily and quickly set byhand at different inclinations to suit the use of such different plates, and it gives a strong and durable construction and can be readily made. By loosening the lever-nut It and swinging the upper end of the plow-standard a backward over the beam-notches against the handle bracearms the foot-bar can be set inclined for a shovel-plate, as seen in Fig. 1', and by moving this end of the foot-bar forward it can be set in a vertical position for the use of a scraper plate, as seen in Fig. 2. To permit of the adjustment of the'foot as in Fig. 1,-

the handle brace-arms are also made adjustable by holes] in the bent end (1 ol' thebeam, so that the brace-arms can be turned upon their pivot f to set them forward or back upon 5 the beam, and secured by the bolt in the holes Z, and to allow of this adjustment the handles are also provided with holes 721., so as to change the connection therewith of the up perends of the brace-arms. These brace-arms [o are also provided with holes 12 at their upper and at their lower ends, whereby the handles can be adjusted higher or lower to suit the height of the plowman, and they can be connected farther forward upon the beam by the r holes 1', when desired, to suit the adjustment of the brace-arms and the inclined or vertical set of the foot.

The foot-bar is formed with ratchet-teeth s on its front side, standing downward, and ratchet-teeth s" on its rear side, standing upward. I provide a supporting-plate I? [or the share, formed as follows: This plate is stamped out of comparatively thin sheet metal with a central hole t, an inwardly-bent lip t at each end, two outward-bent lips I? t at its up per end, and two ratchet-lips 2? I at its upper end. \Vhen seated upon the front side of the foot and the share It placed upon itand se cured by the bolt 1 the lips 2? t fit into the slot of the foot and hold the plate from slipping laterally. The ratchet-lips 15" t engage the ratchet-teeth s and prevent the plate from moving upward, and thus lock the plate to the foot against side and upward movement, 3 5 while the outward-bent lips form abutments for the upper edge of the share, so that the upward strain upon the share is transferred by the plate t to the foot, and thus relieves the bolt. A wedge-piece r is formed with lips at its lower end, which engage the ratchetteeth 8, hold it from slipping downward, and form the seat for the nut a, which secures the share, the plate and the wedge-seat for the nut. By this construction the sharesupport is locked to the foot and the wedge nut-seat is locked to the foot and both the parts 6 and r co-operate to support, to fasten, and to ad just the share and secure the belt at an inclination standing upward in relation to the 5 foot, so as not to interfere with the use of a landside at, as shown in Fig. i. This landside is pivoted to the lower end of the foot, either in the slot or to its outer side, and is pivotally connected at its outer end to the bent end a of the beatn by a bar a9, so that in any adjustment of the latter the landside will maintain a horizontal relation to the beam. To adapt the landside to be reversed end for end as it wears, I provide each of its ends with two holes 2 2, and it may be re ersed edge for edge. To lower the rear end of the landside as it wears, I form its upper end with two or more notches 3 3 or holes, by which it may be secured to the beam by a button 4 or screw and let down as required. The beam is provided with a suitable elevis.

The notches may be made in the side of the beam, and the foot-bar closed at its upper end and secured by a set-screw passing through the side of the foot-bar into the side notches.

I claim as my improvement- 1. The plowbeam terminating in a returnarm a under the beam, combined with the foot-bar c, adjustably clamped at its upper end to the beam and pivoted to the returnarm, the landside a, pivoted to the foot-bar, the vertical bar 00 having notches 3 in its upper end and pivoted to the landside, and the button ion the said return-arm, as shown and described.

2. In combination, the plow-beam terminating in a return end a under the beam, the adjustable handles 9, the adjustable braces, (I (I, the adjustable foot-bar c, the adj ustable landside .r, the adjustable bar .11 and the clamping-button 4., the several parts being arranged and constructed, as shown and described.

33. The combination of the plow-beam having the under return end a and provided with the notches 71, combined with the pivoted foot-bar (2, having slots, the parts i whereof coincide with the beam-notches and the parts i stand oblique from the parts i, and the clamping screw-bolt whereby the clampingboltj, when clamped, is prevented from rising in said slot, as shown and described.
