UNITED STATES PATENT oEEIcE.

EIJWARD 0. GAY, OF RED SPRINGS, NORTH CAROLINA, ASSIGNORl ONE-THIRD TO WILLIAM JONES AND ONE-THIRD TO NORTH CAROLINA. 4

To all whom 'it may concern:

'Be it known that I, EDWARD O. GAY, a citizen ofthe -United States, residing at Red Springs, in the county of Robeson and State -of North Carolina, have. invented certain new and useful Improvements in Plows, of

which the following is a specilication.

My present invention relates to improvements in that class of plows, more especially designed` as cotton plowsV-a'nd in which the4 plow point is so mounted-that'it can be adjusted to the desired angle with respect to the line of draft and according to the condition of the soil to be turned and `the particular work to be performed thereby.

Plowshave heretofore been-provided that -have means for tilting the plow point to the angles desired relatively to the shoe or run-` ner and such operation accomplished without stoppingthe plow, and in many types of plows such adjustments of the plow point is Yeected'loy swingingk lever and rack devices. From practical experience with plows of the general type referred to I have found their structureand operation. openv to 0bjections, partly` for the reason that the'construction is costly and `particularly for the A' reason' lthat in setting the plow, point to the dilferent angles, the relative positions ofthe point and the runner or shoe changes, and

to such an extent that the point when set to dig a shallow furrow frequently rises above the plane of the. riding' face :of the runner or sweep of thev standard 3, vis formed with a pendent enlargement 1d that is formed with" -an upper or guide slot @that isconcentricl with the pivot vpoint of the standardv 3,' 'and a second or lower; slot 5 which is eccentric cheap as to'cost, and in which the set of thepoint is easily eifected while runninghthe plow, more especially has forits purpose to provide for setting the said plow point either shallow or deep without changing the rela-V tive positions of-the point and the runner, or in other words, in such manner that the plow point and the riding face of the runner always remain in the same horizontal -alinement so the runner or shoe always travels in and has a solid bearing on the bottom of thefurrow made by the plow.

'. My invention consists inthe special construction of plow hereinafter fully described,

specifically slet out-in the appended claims head, lhereinafter referred to.. n. y

Specification of Letterslatent. Patented luay 16 1911` Application led February 18, 1911. -Serial N o. 609,312.l i A and illustrated in the accompanying drawings, in which:

' Figure 1, is a perspective view ofmy improved plow, -the plow point being show-n ad- Justed to its most shallow position. Fig. 2, is a side elevation thereof, the parts being in the position shown in Fig. l, the plow point and other parts being shown 1n section. i

Fig. 3, .is a sfide elevation. that shows the plow point adjusted to its maximum lvertical or digging position, and illustrates ythe relation of the point and the runner.l Figa, is

a vertical cross section on th'e line 1E-4 -Kof Fig. 3. Fig. 5, is alperspective view ofthe plow point and vthe yslotted sliding shank or at the front end-of any approved type and its rear end lb is curved downwardly to Iform astandard that is rigidly bolted to the rear end of thefrunner 2, which carries a removable slioe or riding member 20 that is con-, nected to the runner 2 by the'bolt and nut connection' (see Fig. 2), so it may be 're-` moved when worn, and a'l new shoe substi-l tuted therefor.' 'The plow standard 3 ofmy -present construction of plow terminates at the upper end in a handle 3a, while itsl lower end is bifurcated, as at 3" to.` straddle thek ybeam and thel frontend of the said runner 2,

to which it is pivotally connected by the bolt 3.

The 'plow .beam at that part lwithin the.v

with respect to the said slot 4 andthe pivot point of 'the'standard,pthe under edge ofl the.

said pendent portion being curved on an arc concentric with the lower slot 5 for the pur- ,pose presently explained.

9 designates the plow point of any approved shape, and -it is-bolted onto and is l movable with `a movable head casting 6 slidably held with the bifurcated end of the standard `and is vertically movable therein, as the standard is swung backwardly or forwardly to adjustpthe vertical inclination of the plow point.

.to form side arms 60 that straddle the pendent extension of the plow beam and the eccentric slot 5 therein, and the upper ends of the arms 60 carry a cross bolt 6l that..

ridesl in the' said Aslot 5,' a cross piece 62 being-also secured to the upper ends of the straddle arms 60 that engages the lower edge of the pendent beam portion, as is best shown in Figs. 2 and 3. j

7 designates a cross pin on the. standard that passes through the slot l and guides the said standard in its forward .and backward adjustments. The upper edge of the beam has a rack portion 8 concentric with the pivot axis of the standard and with it cooperates the usual spring pawl device SO, operated by the band piece 8l, in the usual manner.

l() designates the plow handles and ll the side braces'therefor. j

By reason of the peculiar construction and. arrangement of the several parts as shown and described it will be apparent `from the drawings that when the plow standard is swung backwardly to give the plow its lowest inclination for shallow diglging, the headthat carries the plow point will, by reason of its peculiar connection with the eccentric slo andthe pendent v'beam portion be forced down to its limit (see Fig. 2) and thereby maintain the point to its initial position, that is, in substantially the plane of the bottom of the runner or shoe, it being obvious that the movement of the sliding head will be upwardly in the standard when the said standard is swung forwardly to adjust the plow point so it re-V tains the position with respect to the run ner, as before referred to.

What I claim is:

l. I n a plow, a plow carrying standard pivotally mounted at the plow end to swing backwardly and forwardly, and means for reciprocally moving the plow point with respect to the standard vasfthe latter is adjusted in reverse directions.

2. In a plow having a fixed runner, a standard pivotally connected to the front end of therunner, a plow point carried by the standard and means for maintaining a `relatively fixed relation between the plow point and the runner as the plow is ladjusted to its digging positions.

8. In a plow of the character stated, the combination with the beam having a downwardly `curved rear end, a runner fxedly mounted -on said end and projected forwardly therefrom, a standard pivotally mounted on the front end of the runner, a plow point carried by the standard and means operable through the movementl of the standard for effecting a sliding movement of the plow on the standard for th purposes specified.

4. In a plow of the character stated, the combination of a beam having its rear end curved downwardly to form a 4standard and a runner fixedly secured to the lower end thereof and projected forwardly therefrom, a plow carrying standard pivotally mounted in the front endof the runner, means on the standard and thebeam for locking the plow' standard to its set position and other means on the standard .and the beam for sliding the plow on the 'standard as the said standard is shifted to its set positions.

5. In a plow of the character stated, Va plow beam having its rear end curved downwardly, a runner {iXedly secured thereto and projected forwardly from they said curved portion, a standard that straddles the beam and the runner and is pivotally secured to the front end' of the runner, said beam having a pendent extension provided `with a slot eccentric to the pivot of the standard, a head member slidably mountedv -end of the standard and bolted to the sliding head to move therewith.
