UNITED STATES CHARLIE ELMERHBABBE'IT, or DALLAS, TEXAS.

.Ap pli c tion filed, July 7,

To all whom it may concern:

Be it known that I, CHARLIE E. BARRETT,-

a citizen of the United States, residing at Dallas, in the countyof Dallas and State of Texas, have invented certain new and use ful Improvements in a Plow Stock and Foot, of which the following is a specification;

This invention relates to a plow stock and foot structure and it consists in the novel features hereinafter described and claimed.

An object of the invention is to provide a plow stock and foot structure of simple and durable arrangement and adapted to be applied to the beam of a plow, there being means provided for varying the angle of inclination of the stock with relation to the beam and means provided upon the stock for varying the angle of inclination of the plow shovel with relation to the stock.

A further object of the invention is to provide means for pivotally connecting the plate with the stock and resilient means for holding the plate normally at the desired position with relation to the stock. I

In the accompanying drawing:

Figure 1 is a fragmentary side elevation of a beam with the plow stock and foot applied, showing parts broken away and parts in section.

Figure 2 is a detailed side elevation of the lower portion of the stock, and the plow plate applied thereto showing parts broken away and parts in section.

As illustrated in the accompanying drawing the plow beam is shown at 1 and a brace 2 is applied to the under side thereof. The stock 8 is approximately U-shaped in edge elevation and its opposite side portions lie at the opposite sides of the beam 1 and brace 2. The stock 3' is pivotally connected with the brace as at 4. A' bracket 5 is applied to the upper side of the beam 1 and is provided with a series of perforations 6 which are disposed in a row longitudinally of the beam 1. The intermediate portion of the bracket 5 is elevated with relation to the upper surface-of the beam 1 and a bolt 7 passes under the intermediate portion of the bracket .5 and engages with the opposite sides of the stock 3. Spaced lugs 8 are located between the side portions of the stock 3 and a pin 9 passes'transversely through a lug 8. A lever 10 is fulcrumed between the upper portions of the stock 3 and is pivotally connected with the upper end of the pin 9. A spring llis coiled around the intermedi- :pnow s'rocx AND r001".

ate portion of the, pin 9 and the upper end of the spring bears against the under surface of the lug 8. Thelowerend of the spring 11 bears against the pin 12 which passes transversely through the pin 9 and which is located'between the lugs 8. It will be observed that when the rear end of the lever 10 is elevated, the pin 9 is moved vertically and the spring 11 is compressed. Therefore the said pin is lifted out of'one of the perforations 6 and when the said pin is thus disengaged from the bracket 5 the stock 3 may be swung upon the pivot 4 and the said stock may be adjusted to a desired angle with relation to the beam 1. When the lever 10 is released the spring 11 expands and the lower disposed lug 13 is carried at the intermediate portion of the stock 3 and a plow plate 14 is pivotally mounted at the lower end of the stock. Bars 15 are attached to the upper portion of the plate 14 and extend transversely of and rearwardly with relation to the lower portion of the stock 3. The rear ends of the bars 15 are pivotally connected with a link block 16 and the said block 16 lies between the bars 15. The forward end of the link block 16'is pivotally connected with the lug 13 as at 17. A bolt 18 is threaded through the rear portion of the link block 16 and itsupper end engages the lower surface of the lug 13. A bolt 19 is I 19 and a coil spring 21 is interposed between the under surface of the wing nut and the upper surface of the lug 13 and is under tension with a tendency to hold the rear end of the link block 16 in an elevated position and the upper end of the bolt 18 in engagement with the under surface of the lug 13.

By adjusting the bolt 18 in the link block 16, the bars 15 and the plow plate 14 may be swung whereby the said plate 14 may be disposed at a desiredangle with relation to the stock 3. When the plow is in operation and in the event that the plate 14 should strike an obstruction in the soil the said plate 14 will swing upon its pivotal connection with the stock 3 as the stock and the beam passes over the said obstrintion and under the influence of the spring 2L the plate 14- will be returned to its normal position with relation to the stock 3. Thus when the plow is moved in a. rearward direction the plate 14 may be swung with relation to the. stock 3 and when the plow is lifted to dis engage the plate H from the soil, the tension of the spring 21 comes into play whereby the bars 15 are swung and the upper end of the bolt 18 is brought in contact with the under surface of the'lu'g 3.

Having thus described the invention, what I claim is In combination with a plow beam, a bracket member mounted upon the upper side of the beam and having its intermediate portion elevated with relation to the beam andi-provi'ded with a series of openings, a bolt'passing' transversely between the intermediate portion of the b-a'cket member and the plow beam, a stockattached to the bolt, means for pivoting the stockbelow the beam, the side portions of the stock lying at opposite sides of the beam and the bracket, spaced lugs located between the upper side portions of the stock, a pin passing through the lugs and adapted to engage in the openings of the bracket, a stop member on the pin, a spring located between the lugs and bearing at one end against one of the hugs and at its other end against the stop me '1 her on the pin, and a lever fulcruined between the side portions of the stock and pivotally connected with the pin to actuate the pin out of one of the openings and out of engagement with the bolt with which the spring normally holds the pin in engage ment.

In testimony whereof I aflix my signature.

CHAR-LIE ELMER BARRETT.
