WHEEL-PLOW.

SPECIFICATION forming part of Letters Patent No. 425,592, dated April 15, 1890.

Application filed January 8, 1890. Serial No. 336,272. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH O. BOUGHNER, a citizen of the United States of America, residing at Paris, in the county of Bourbon, in the State of Kentucky, have invented certain new and useful Improvements in \VheeL Plows, of which the following is a specification.

My invention has relation to improvements in wheel-plows, and the object is to provide a plow of the character and class named which may be readily adjusted as to the depth of the furrow by changing the height of the carriage in its relation to the wheels, and also to provide improved means whereby the plow is relieved from the efiects of its contacts with impediments in its course and easily released from such contact without backing the team and carriage.

I attain the object of my invention by the means illustrated in the accompanying drawings, wherein- Figure l is a side view of the plow, the wheel being removed. Fig. 2 is a plan view. Fig. 3 is a longitudinal section on the line a; a: of Fig. 2, showing a segment of the swingin g frame, its supports, and the lever and 0011-.

necting-rod in side view. Fig. 4 is a detail of the foot-lever which looks the swinging frame in position. Fig. 5 is a perspective of the axle and adjusting means. Fig. 6 is a perspective of the swinging frame removed from the carriage, showing the plow attached thereto.

A designates the carriage-frame, made of substantial stuff of such size and strength as may withstand the strains to which it will be subjected and to meetthe purposes of tillage. This frame is composed of side pieces 1 2, connected at the front and rear by top and bottom cross-pieces 3 4 5 6. To the under side of the said pieces of the frame are secured boxhousings, consisting of the inner piece 7 and side pieces 8 9, having inward-projecting flanges 10, leaving the outer side open and forming a housing for the vertically-arranged portion of the axles to slide in. The axles consist of a short arm having spindles 11, carrying the wheels, and vertically-arranged sliding boxes 12, having rabbets 13 in their outer corners to engage the flanges of the housings. These sliding boxes have a hole formed through them from top to bottom, and in this is arrangeda threaded nut 14,1et in by means of a mortise 15, forming a seat for the nuts.

Through the side pieces of the frame are projected lifting-screws 16-17, having keepers or washers 18 19 above and below the side pieces, which keep the stems of the lifting-screws from moving up ordown when they are turned by means of the handles 20 on their upper ends. The lower parts of the lifting-screws are provided with threads 21, which engage the nuts in the sliding boxes.

The keepers 18 are formed with steps 22, which are engaged by a pawl 23, mounted on the side pieces, and serve to hold the lifting screws in fixed vertical position. By turning the lifting-screws up or down a corresponding movement is given to the sliding boxes carrying the aXle and wheels, and the carriage is thus adjusted to any desired height.

On the inner side of each side piece of the carriage, at near each end thereof, are secured arms 24 25, arranged to project downward and at inclines, as shown. In these arms are formed ways 26, having their lower end walls formed to correspond to the curvature of the segments of the swinging frame. These ways serve as seats and guides for the segments in their movements. In bearings 27 28 on the carriage is mounted a shaft 29, having fixed thereon two lever-arms 3O 31, to the lower ends of which are connected rods 32, which extend back and have their ends attached to the segments of the swinging frame. To the top of one of the lever-arms, as 30, is fixed a lever 33, extending back, as shown, which enables the operator to shift the swinging frame from the rear of the carriage.

B designates the swinging frame. This consists of two segments of a circle 34 35, lodged in the ways 26 of the arms 24 25. These segments are connected at their forward end by a cross-piece 36, have a cross-piece 37 forward of the middle of their are to hold the clevis end of the plow-beam, as shown at 38, and at the rear end the segments are connected by a cross-piece 39, which supports and steadies the plow-beam. It will be observed from the foregoing description that by moving the segments the plow necessarily moves with them.

0 designates the plow, of which there may be two, if desired, one only being shown in the illustration. The end of the plow-beam is provided with'a clevis, as shown, which is connected to a clevis 40 on the cross-piece 37, and the rear end of the beam is secured to the cross-piece 39 by means of hooks 41, having threaded stems, a keeper-bar 42, and nuts 43.

D designates the tongue, having its rear end extended the length of the frame, as shown, and detachably secured between the cross-pieces by means of bolts 44 45. On the frame is a seat-support and brace-piece 46, having arranged thereon the drivers seat 47. On the tongue is pivoted a foot-lever 48, having a downward-projected arm 49, arranged to engage behind the cross-piece 36 and formed with a foot or hand piece 50, arranged conveniently to the driver. A keeper 51 may be arranged on the lever 33, which aids in keeping the swinging frame in position.

The operation of the plow is as follows: The carriage being adjusted by means of lifting-screws to such a height as to'suit the team and the depth of the furrow, the foot-lever on the tongue is dropped into holdingposition, and the plowing may begin. In case the plow strikes an obstruction and stops its progress the foot-lever is lifted out of its engagement behind the cross-piece of the swinging frame, which leaves theswinging frame carrying the plow to bemove'd' backward by the lever 33, which 'operatio'n not only carries the plow back and out of contact with the obstruction, but also lifts it up free to be moved over the obstruction. After the plow has been released from the obstruction the swinging frame is moved forward, the foot-lever arranged to again hold the frame in position, and the plowing resumed.

Having thus legally described my inven 'tion and explained the principle thereof and the mode of applying that principle so as to ing frame B, having curved segments ar ranged in said ways, and a lever on the carriage to move the swinging frame, substantially as and for the purpose specified.

2. In a wheel-plow, the combination of a ,frame provided with downward-projecting arms having ways 26 formed therein, a swinging frame B, having curved segments arranged in said ways; a lever on the carriage to move the swinging frame, and a leverto lockthe" swinging frame in a fixed position substantially as and for the purpose specified.

3. In a wheel-plow, the combination or a carriage-frame provided with downward-projecting arms 24 25, formed with ways 26, the

swinging frame B, having curved segments 34 35 arranged in said ways, ash'aft 29,-1nonnted on the carriage-frame, le'vei -a'rrns on the shaft connected to the segments, and aplow secured to cross-pieces of the swinging'frame, substantially as described.

4. In a Wheel-plow, the combination of the carriageffaine, the swinging frafne arranged under the carriage-frame andcarrying the plow-beam, the tongue on the carriage-frame, and a foot-lever pivoted to the tongue and provided with a downward-projecting arm to engage the swinging frame and loc'kit in forward position, substantially as described.

In witness whereof I have herenntoset my hand in. the presence of two attesting witnesses. p

JOSEPH C. BOUGHNER.
