Specification of Letters Patent.

Patented Nov. 10, 1908.

Application filed November 19, 1907. Serial No. 402,872.

To all whom it may concern:

Be it known that I, JOHN MARK SAUSSER,

'a citizen of the United States, residing at Osnaburg, in the county of Stark and State of Ohio, have invented a new and useful Plow, of which the following is a specification.

This invention relates to plows and one of its objects is to provide means whereby the width of a furrow to be cut by the plow can be regulated at the will of the operator and during the operation of the plow.

Another object is to provide simplified means for regulating the depth of the out.

A still further object is to provide means whereby either or both the width and the depth of the out can be adjusted in a simple and efiicient' manner.

. With these and other objects in view the invention consists of certain novel features of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claims.

. In the accompanying drawings is shown the preferred form of the invention.

In said drawings: Figure 1 is a side elevation of a plow embodying the present improvements, the guide plate of the adjusting attachment bein shown in section; Fig. 2 is a plan view of t e adjusting mechanism of the low; Fig. 3 is a side elevation showing a moc ified form of adjusting mechanism in which two levers are employed; Fig. 4 is a section on line xx, Fig. 3; Fig. 5 is a side elevation showing another modified construction; and Figs. 6 to 12 inclusive are detail views of modified forms of depth regulators which may be used in lieu of the forms shown in Figs. 1, 2 and 3.

Referring to the figures by characters of reference, 1 is the beam of a plow to the front portion of which is ivotally connected a laterally movable widt 1 regulating clevis 2 having a plurality of o enings 3 therein any one of which is adapted to receive a laterally extending pivot bolt 4 which extends through the ends of a yoke 5 constituting the base portion of the depth regulating clevis of the plow. Another yoke 6 extends upward from the apertured endof the yoke 5 and the top thereof is connected with the forward portion of the yoke 5 by means of a curved brace 7. An eye 7' projects beyond the yoke 5 and-constitutes means whereby the draft; appliances can be readily fastened to the c evis. Bolted or otherwise secured to the brace 7 is the forward end of a lever8which extends longitudinally above the beam 1 to a point within convenient reach of the operator.

Secured upon the beam 1 is a laterally extending guide plate 9 having a rod 10 supported thereabove in any preferred manner as by means of ears 11. Teeth 12 are formed upon one edge of the plate 9 and are disposed in a line parallel with the rod 10. Slidably mounted on the rod is an upstanding guide loop 13 which straddles the lever 8 and has a guide strap 14 extending from one side of the loop 13. This loop is formed with rack teeth 15 designed to be engaged by a spring pressed plunger 16 mounted on the lever 8. The plunger is disposed to be retracted by means of a small lever 17 ivotally connected to lever 8 near its hand e 18 and attached to the plunger by means ofa rod 19.

Slidably and pivotally mounted on the rod 10 and embracing the lower portion of the loop 13 is an L-shaped loop 20, the u standing portion of which is designed to e frictionally engaged by a spring controlled head 21 which is slidably mounted on the lever 8 and designed to be manually operated by means of a small lever 22 connected to the lever 8 near the handle 18. The elbow 23 of the loop 20 normallyfrests by gravity in engagement with the teeth 12. It is to be understood that the plunger 16 normally engages the teeth on the loop 13 while the head 21 is normally out of engagement with the loop 20 and is disposed to frictionally engage the same when lever 22 is depressed.

When the plow is being pulled forward and it is desired to adjust the depth of a cut' this can be best accomplished by changing the line of draft. This change can be readily effected by releasing the plunger 16 from engagement with the rack teeth 15 and swinging the lever 8 vertically so as to move the depth regulating clevis upon its pivot 4. The loops 13 and 20 will act as guides for the lever during this operation and will be prevented from moving laterally because the elbow 23 en ages the teeth 12. Should it be desired to c ange the width of the cut the head 21 is thrown against the loop 20 so as to swing it backward out of engagement with the teeth 12 whereupon the lever 8 can be swun laterally so as to cause the loops to trave along the rod 10. This will result in both of the clevises 2 and 5 swinging later- I ally upon the ivot of the clevis 2. As soon as the desire lateral adjustment has been the head 21.

.means of a smal obtained the head 21 is released andthe loop 20 drops by gravity into engagement with the teeth 12 thereby locking the parts in ad-' justed position. Obviously both the de th and the width of the cut can be simu taneously adjusted by disen aging plunger 16 from the teeth 15 and pulling backward on The lever 8 can then be moved vertically and laterally and by releasing the plunger and the head said lever will be positively locked in the position to which it is adjusted.

In Fig. 3 has been shown adjusting mechanism in which two separate levers are employed, one being provided for the depth adjustment and the other for the width adjustment of the plow. This arrangement will be deemed most acceptable to some persons because less skill is necessary to operate it. It will be seen by referring to this modified construction that the lifting lever 24 is connected to the depth regulating clevis 25 in the same manner as in Fig. 1, whereas the width adjusting lever 26 is secured to a tongue 27 extendin rearwardly from the pivoted width regu ating clevis 28. The two levers extend rearwardly above thebeam 1 and the lower lever 26 rests upon an angular guide bar 29 secured to the beam 1 and extending transversely thereof. The upstanding portion of this bar has a series of apertures 30 therein any one of which is disposed to receive a spring pressed plunger 31 connected to the lever 26 and adapted to be retracted by means of a small lever 32. Ears 33 extend upward from the ends of the bar 29 and support a guide rod 34 which extends transversely above the lever 26. A guide loop 35 is pivotally connected to the lever 26 and straddles the lifting lever 27. This guide loop and the lifting lever are held in proper relation to each other preferably by means of a guide strap 36. A spring pressed plunger 37 is connected to lever 24 and is designed to project into any one of a seriesof apertures 38 formed in one side of the loop 35. This plunger 37 may be withdrawn from enga ement with the loop by I lever connected to the lever 24. When it is desired, with this modified construction, to regulate the depth of the cut, the plunger 37 is disengaged from the loop 35 and the lever 24 is swung with the pivot of clevis 25 as its fulcrum. The front end of said clevis will therefore be raised or lowered as may be desired. To swing the clevis laterally so as to regulate the width of the cut plunger 31 is disengaged from the bar 29 and lever 26 is swung laterally so as to cause the clevis 28 to swing u on its pivot. In Fig. 5 I have shown anot er modified construction in which a lifting lever 39 and a width regulating lever 40 are used. Only the lifting lever 39 extends backward to points adjacent the handles of the plow,

cent a transversely extending guide bar 41.

This lever 40 has a guide loop 42 connected to the end thereof and provided with rack teeth 43 designed to be engaged by a spring pressed plun er 44 upon lever 39. The 00p 42 straddles ever 39 and is held in proper relation thereto by a strap 45. An L-shaped loop 46 is provided with lu s 47 at its heel ortion which straddle the ever 40 and the ottom member of this loop has a locking pin 48 pivotally connected to it and mounted to recip rocate within lever 40. This pin normally engages one of a series of apertures 49 formed with the bar 41. A spring controlled pawl 50 is slidably mounted on lever 39 and is normally held out of contact with the loop. 46. With this construction when it is desired to regulate the depth of the cut the (plunger 44 is disengaged from loop 42 an lever 39 swung vertically and when it is desired to regulate the width of the cut the head 50 is drawn against loop 46 so as to withdraw pin 48 from engagement with bar 41.

tance and will carry the lever 40 therewith. Although the depth regulating clevis is preferably constructed as shown in Figs. 1, 2

Lever 39 can then be swung laterally -a desired disand 3 it is to be understoodthat clevises of other forms may be utilized without affecting the operation of the device. For instance, in the form of clevis shown in Fig. 11 the brace 7 is eliminated and instead the base yoke 51 and the u standing yoke .52 I;

constitute the entire .0 evis. Instead of forming the clevis of yokes, the same can'be made up of solid strips as shown in Figs. 6, 7 and 8 or, if preferred, the clevis can be angular in elevation as in Fig. 9, which construction can be provided with a reinforcing brace 53, as shown in Fig. 10. In Fig. 12 the clevis consists of nothing more than a looped stra having one end portion curved upward an desi ned to la an ob'ect secured to one end" of a ifting lever 54. In all ofthese modified constructions apertures 55 are provided whereby they can be pivotally connected to the width regulating clevis which has been shown at 2 and 28 in Figs. 1 and 3 respec-- tively.

It will be seen that a plow having adjusting mechanism such as herein described can be quickly regulated to increase or diminish the width and depth of a furrow without the eral and vertical swinging movement, and a leverfixedly connected to the clevis, the bearings of the clevis constituting the ful- Cir 2.

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