PLOW.

SPECIFICATION forming part of Letters Patent No. 596,372, dated December 28, 1897. Application filed June 15, 1897. Serial No. 640,852. (No model.)

' tion, reference being had to the accompanyin g drawings.

The special objects of the present improvements are to render the plow light and strong and easyrunning, reducing the effort required by the plowman to handle the plow to a minimum, and to render the handles and beam and plow-plate readily adjustable as regards pitch and height, as more fully hereinafter set forth.

Referring to the drawings, Figure 1 is a side elevation of the plow complete, a part being broken away to show the adj ustability of the plow-plate; Fig. 2,.a plan view thereof;

Fig. 3, arear view of the stock detached, and Fig. 4 a rear view of the plow-plate detached.

Referring to the drawings by letter, a designates the foot or front standard of the stock, I) the foot-bar, which extends rearward from the lower end of the foot a, c the rear standard connecting the rear end of bar I) to an upper connecting-bar d, and e an arched brace connecting the bar d to the standard 0 about midway the length of said bar and standard, these several parts being cast integral and forming a strong skeleton stock. Cast integral with the upper end of the foot part a are a pair of plates f, which extend upward and embrace the beam g, and extending through the plates and beam is a horizontal pivot-bolt f. Cast integral with the stock at the upper end of rear standard 0 are a pair of upward-extending plates h, which embrace the beam at a point a suitable distance to the rear of pivot f, these plates being provided with coincident holes through which and a suitable hole in the beam a removable eyebolt or pin is passed, this arrangement permitting the beam to be elevated or depressed at its rear end. Pivoted on op posite sides of the stock at the upper end of the rear standard are the handles 2', beveled lugs j being formed on the stock to serve as bearings for the handles at their pivotal points and the bolt lo serving as the pivot.

The lower ends of the handles project downward and forward from the pivot and are adjustably clamped or held against the opposite sides of the arch-brace by means of a removable pin or bolt Z, the arch-brace being provided with a series of holes to permit the pitch of the handles to be readily varied.

It will be observed that the foot-bar b is beveled throughout its length to a V shape,

and that in a vertical central slot formed in its rear end is mounted a colter-blade m, this blade being pivoted at its forward end in the front end of the slot and having its rear end extended a little beyond the rear end of the stock and made adjustable in order that it may be raised or lowered. The colter is rendered adjustable by means of a removable pin or key m passing through its rear end and engaging notches in the rear edge of the stock on opposite sides of the colter, a series of the notches being provided to permit of a series of adjustments. The advantage in beveling the foot-bar and attaching the colter thereto is that the plow can be more easily handled and guided, the colter and beveled edge entering the earth far enough to prevent swerving.

It will be evident that any style or pattern of plow-plate may be used in connection with our improved stock. In. the drawings we have shown a plow of the double-sweep variety, the sweeps of which are set low in order to lighten the draft. The plow is fastened to the standard by a bolt n, which passes through the plow and standard, a series of holes being formed in the standard to permit the plow to be adjusted and to accommodate plows of other sorts. The holes in the standard are preferably made angular a part of their length, so that when but a single fastening-bolt is employed the tendency of the plow-plate to shift sidewise is avoided. Riveted on the back of the plow-plate are two bars or plates 0, one being secured on each side of the standard and close up to the same, whereby the plow-plate will be held steady and braced. The bars 0 extend downward and afford a support for the removable point p, which is bolted thereto. The bars 0 not only prevent the plow-plate from shifting sidewise, but also serve to strengthen the sweeps or moldboards.

It will be observed that an essential feature lies in the manner of supporting the beam, it being readily adjustable with respect to the plow-point, the plowman being enabled to vary the adjustment from his position at the rear of the plow. This providing for the adjusting of the pitch of the plow-beam is advantageous, since the plowman can readily adapt the plow for different kinds of work and different varieties of plow-shovels.

The manner of supporting the handles is also advantageous, it being well known that the nearer the lower ends of the handles extend to the plow-point the greater will be the ease with which the plowman handles the plow, and mounting the handles pivotally on the stock enables them to be adjusted with respect to their pitch independently of the beam, which is an essential feature, especially in view of the fact that the beam is made adj ustable.

The advantage in mounting the colter in the slot in the rear end of the foot-bar and having the securing-notches in the rear edge of the bar is that the liability of the colter getting fastened by reason of rust and clogging of dirt is reduced to a minimum.

Having thus fully described our invention, what we claim, and desire to secure by Letters Patent, is-

1. The combination of a plow-stock, consisting essentially of a front standard a, a rear standard 0, upper connecting-bar d, and lower connecting-bar I), a pair of plates f being formed integral 011 the upper end of standard a, and a pair of separated plates h being formed integral with the rear standard and projecting vertically therefrom, these plates being separated and provided with registerin g holes, aplow-beam pivotally mounted and fitted between the forward plates f, the rear end of said beam fittin g closely and working vertically between said plates h, a pin or bolt passing through the holes in the plates and engaging the beam, and a pair of handles supported on the stock independently of the beam, whereby the beam may be adjusted without varying the pitch of the handles.

2. The combination of a plow-stock, composed of a front standard CL, rear standard 0, upper connecting-bar cl, lower connecting or foot bar Z) and a diagonal arch or brace a connecting the rear standard to said upper bar (1, oppositely-projecting lugs j being formed on the upper end of the rear standard 0, a pair of handles pivoted respectively on said lugs and having their forward ends extend down to said brace or arch, means for connecting the ends adjustably to said arch, and a beam supported on the stock independently of the handle.

3. The combination of a plow-stock having a rearward-extending foot-bar, a colter-plate pivoted at its forward end and lying in a vertical longitudinal slot in the rear end of the foot, and a removable pin carried at the rear end of the colter-plate and engaging notches in the rear edge of the foot-bar, substantially as described.

4. The combination of a plow-stock, a double-sweep plow attached to the standard thereof, a pair of bars 0 attached to the rear side of the plow, one on each side of the standard, and extending downward and forward, and a removable plow-point bolted to the extended ends of said bars, substantially as de scribed.

In testimony whereof we affix our signatures in presence of two witnesses.
