PLOW.

SPECIFICATION formingpart of Letters Patent No. 711,531, dated October 21, 1902.. Application led Agust 15,1902. f serial No. 119,122. (No model.)

.To all whom it may oon/cern:

Be it known that 1, BEVERLY GRAY REEVES, a citizen of the United States", residing at Durango, in the county of Falls and State of Texas, have invented a new anduseful Plow, of which the following is a specification.

This invention relates to that class of plows in which a stock or standard is pivoted to and adj ustably connected with the beam and it 'has for its object to provide an improved construction, arrangement, and combination of parts whereby the said adjustment may be effected in a convenient manner and by which the standard when adjusted may be securely retained in position. p

My invention further consists in the improved construction ofthe detailed parts of the plow and of a drag attachment for the same, which will be hereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawings, Figurel is a side view of a plow constructed in ac- Fig. 2 is a sectional View takenon the line w Fig. 1. Fig. 3 is a sectional view faken onthe line y y of Fig. l. Fig.`4is a sectional view taken on the line z c' of Fig. 1. elevation.

Corresponding parts in the several figures are indicated by like characters of reference.

1 designates the plow-beam, the rear end of which is curved approximately to a semicircular shape. The foot end of the beam is provided on opposite sides with recesses 2 2, in which are seated the rearwardly-extendin g clamping-plates 3 3, the forward ends of the upper edges of which abut againstthe shoulders 4 at the upper edges of the recesses 2. The plates 3 are secured in position by means of a transverse pin 5.

Between the clamping-plates 3 3, near the rear ends thereof, is mounted the L-shaped drag 6, which consists of a steel bar of suitable dimensions bent at right angles and having its vertical arm inserted'between the clamping-plates 3, where its upper forward end rest against a transverse pinv or rivet 7, while its rear side has a bearing against a clamping-bolt 8, which also extends transversely through the plates, near their lower rear corners, and which is provided with a Fig. 5 is a rear nut 9,'which may be tightened so as to hold the drag securely in positionat any desired point of vertical adjustment. The handles 10 10 are also secured to the clamping-plates, upon the outer sides of the latter, by means of transverse pins or bolts 11, which are arranged diagonally With relation to the pins 7 and bolt 9, thus providing additional sup:

ports for the vertical member or shank of the drag.

The standard proper, which is designated l2, is composed'of two plates or bars 1313, which are of an elongated-S shape and'which are placed on opposite sides of the beam with which they are connected, near the point or foot end thereof, by means of a transverse spaced at their lower ends by an interposed y block 16, through which a connecting bolt or rivet 17' extends.

The parts thus far described are preferably constructed of steel.

I shall now proceed to'describe the adjusting mechanism, which is mainly to be constructed of cast-iron.

18 designates a plate or bracket secured to the curved part of the beam and extending rearwardly from the same. The said bracket is provided on one side thereof with an annular rim or collar 19, surrounding a perforation 20which is to receive a pin or bolt 21, by means of which the said bracket is con-l nected with the end'of one arm of a bellcrank lever 22, which said arm is provided with an opening 23, whereby it has a pivotal i movement upon the flange 19. The other upwardly-projecting arm of the bell-crank lever is formed at its upper edge vwith a toothed segment 24, and at its fulcrum it has an annular rim or flange 25l surrounding a perforation 26 to receive a pin or bolt 27,`

whereby it is connected with the operatinglever 2S,Which latter has a perforation where-y by it is mounted upon the flange 25, on which it has apivotal movement. `The lower ICO end of the lever 28 extends between the plates 13 of the standard l2 at the upper end of the latter, and it has pivotal connection with said plates by means of a pin or bolt 29. The operating-lever is provided on one side thereof with lateral projections or brackets 30, which are perforated for the passage of an operating-rod 31, which is provided at its lower end with a tooth 32, engaging the toothed segment of the bell-crank lever 22. The upper end of the rod 31 is bent to form a handle 33, which may be conveniently grasped by the operator. The operating-rod 3l is also provided near its lower end with a shoulder 34 to receive the impact of a spring 35, which is coiled upon the said rod and the upper end of which has a bearing against the under side of the upper projection 30.

The operation of this invention will be readily understood from the foregoing description, taken in connection with the accompanying drawings. By means of the op erating-lever when the tooth 32 is disengaged from the toothed segment 24 the standard may be adjusted to any desired tilt, thus causing the plow, the blade of which is attached in the usual manner to said standard, to run deep or shallow, as may be desired. The standard will be locked in its operative position by the tooth 32 engaging the toothed segment 24. The drag also may be very readily adjusted when the bolt 9 is loosened so as to release the grip of the clamping-plates upon the shank of said drag.

The component parts of my improved plow may be manufactured of any desired material and of any desired dimensions, and Ireserve the right to make any changes as to the detailed construction and arrangement of the parts which may be resorted to without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a plow the combination of a beam provided at the foot thereof with recesses having shoulders at their upper edges, rearward-extending plates seated in said recesses and secured by transverse fastening means, adrag having a shank disposed between said plates, apin connecting the latter and forminga support for the upper front edge of said shank and a clamping-bolt connecting said plates at a point diagonally opposite to said connecting-pin, substantially as set forth.

2. The combination of a plow-beam, clamping-plates extending rearwardly from the point thereof, a drag having a shank disposed between said plates, a pin connecting the latter and forming a support for the upper front edge of said shank, bolts supporting the handles of the plow and extending transversely through the clamping plates and forming points of support for the shank of the drag, and a bolt extending transversely through said clamping-plates at the heel ends thereof and provided with a clamping-nut, said bolt forming a point of support for the rear edge of the shank of the drag, substantially as set forth.

3. The combination of a plow-beam, having recesses on opposite sides of the point thereof, the clamping-plates secured in said recesses, the standard-blades having pivotal connection with the plow-beam by means of a pin passing through the clamping-plates, a spacing-block at the lower ends of said standardplates, a bracket extending rearwardly from the beam, a bell-crank lever having one end pivotally connected with said bracket and having a toothed segment at its other end, an operating-lever fulcrumed at the angle of the bell-crank lever and having its lower end extended between the upper ends of the standard-plates and pivotally connected therewith, and means carried by the operating-lever for engaging the toothed segment of the bellcrank lever thereby retaining the parts at any point to which they may be adj usted, substantially as set forth.

4. The combination of a beam, a bifurcated standard having pivotal connection therewith, a bracket secured to the beam, extending rearwardly and having a perforation reinforced bya surrounding flan ge, a bell-crank lever, one of the arms of which has pivotal engagement with said reinforcing-flange and the other arm of which terminates in a toothed segment, said bell-crank leverbeing provided at the angle thereof with a transverse perforation reinforced by a surrounding flange, an operating-lever mounted pivotally upon said flange, a pivotal connection between the lower end of the operating-lever and the upper end of the bifurcated standard,'connectin g means at the several pivotal points, and means carried by the operating-lever for engaging the toothed segment of the bell-crank lever, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two witnesses.

. BEVERLY GRAY REEVES.
