PLOW-LIFT.

adapted to be engine drawn. and used in An object of the present invention is to provide means for automatically lifting the plows and holding the same above the ground surface when the plows are not in use, and for automatically dropping the plows to the desired distance in the earth when the plows are in use; and to provide means for engaging or measuring the depth of the plows relatively to a prior formed furrow, or furrow turned up by an advanced plow. v

The invention also has for an object the provision of a peculiar mounting for'awheel upon a plow beam for supporting the latter by the wheel, and also for raising and lowering the beam by the vertical movement of the wheel whenfrolled into and out of furrow; and to provide a wheel mounting or connection comprising relatively few parts and which are automatically moved relatively to one another incident to the change in the angle of the plow beam relatively to a draft frame employed.

The above, and various other objects and advantages of this invention will be in part described, and in part, understood, from the following detailed description of the present preferred embodiment, the same being accompanying drawings, wherein Figure 1 is a side elevation of a traction or engine drawn plow having the improvements of this invention applied thereto and showing'" the plow in operation with the point in a furrow. r

Application filed November 1, 1917. Serial No. 199,781. V i i A 6 is a fragmentary enlarged sideele- I vation of the lifting wheel arm, the supporting'beam forthe arm, and the .operating leverlconnected and carried by the arm.

Fig. 7 is a vertical section through the same taken substantially. on the plane 'indicated by the line 77 in Fig. 6.

Fig. 8 is a top plan view ofthe guide em? Referring to the accompanying drawings, the invention is disclosed as applied toagang plow of the engine drawn type, and where'inl-O designates a draft frame of an '70 pler or clevis 11 to whicheis' pi-votally con-'- nected a pair of p'low beams 12. The beams" ployed for supporting the-wheelarm.

suitable construction provided with a cou- 12 are held in spaced apart'r elation by-bosses 13 arranged between the forward and rear'.

end portions of the beams. The beams 12 plow are provided at their rear ends with points 14: of usual. construction.

One of the beams 12, preferably the on the outer side, or the side toward-which the wheel of. the adjacent plow is formed, is

provided with a vertical guide or way'15 which, as shown in detail in Fig; 8, may com prise a casting having a plate or body por-' tion adapted to be bolted or otherwise suitably secured against the outer face of the V beam 12 for supportingthe guide body 15 rigidly upon the beam." The guide is pro vided with outstanding substantially parallel flanges overturned at their 'out'er edg'e portions andextending toward each other to form an undercut or keyislot in the guide;

Slidably mounted in the. guide 15 is one end beam 2 of an arm 16, which end is relatively straight;

and adapted 'for'vertical movementfin' the guide. The arm 16' is bowed upwardly and has its other end relatively long and projecting down toward the ground in laterally spaced relation from theplane of theibeam 12.) "Thelonger'end'ofthe armf16 has piv. oted thereto a combined supporting 'and liftingwheel 17, and isprovided with a base '18 forming with thelower'end of the arm 16 a fork within which the wheel'17 is-mountedf Thewheel 17 V and its arm 16are adapted to rise and fall as thejwheel passes over undulations in the groundv The inner end of the arm'16 is provided with a pivot 19, shown-in Fig. 7 in the form of a bolt, and upon-which is pivotally mounted between its ends a lever20. One

end of the lever20, the rearend thereof, is

connected by a link 21 to the rear end of the adjacent plow beam 12, while the outer or forward end of the lever 20 is connected by a rod 22 to a depending bracket 23 carried upon the rear end of the draft frame 10. The connecting rod 22 is of such length that when the plow is drawn over the upper 'irface of the earth with the supporting and lifting wheel 17 traveling substantially in the same horizontal plane as that of the carrier wheels of the draft frame 10, the lifting lever will be swung upon the link 21 'ito a position to force the arm 16 downwardly and thus raise the beam 12, and the plow points 14 connected thereto. The lever 20 and the connecting rod 22 are of such relative length that the plow points 14: are elevated a considerable distance above the surface of the ground when the combined lifting and supporting wheel 17 is traveling thereover. As shown in Fig. 1, however, as soon as the lifting wheel 17 drops into a' furrow, the angle between the draft frame 10 and the plow beam 12 is lessened and approaches a straight angle with the result that the linear distance between the pivotal point of the lever 20 upon the arm 16 and the forward end of the connecting rod upon the draft frame 10 is lessened and the forward end of the lever 20 is raised and the beams 12 are lowered. The connecting rod 22 is of a predetermined length in order to drop the plow points 14 into the ground the desired distance. The arm 16 is so curved that the ends thereof substantially bridge the space between the furrow formed by the adjacent plow 14 and the prior formed furrow. The supporting wheel 17 is adapted to travel in the prior formed furrow and to, thus adjust, automatically, the position of the plow points 14 in the ground to form the new furrows.

It is of course understood that various changes and modifications may be made in the details of construction and design of the above specifically described parts of this invention without departing from the spirit thereof, suchchanges and modifications be ing restricted-only by the scope of the following claims: I claim: I I

1. The combination with a-draft frame, a plow beam pivoted thereto, and a plow point carried by the plow beam, of an arm slidably mounted .for substantially vertical movement upon the plow beam, a supporting wheel connected to the lower end of the arm adapted to travel over the ground, a connection between said arm and the plow beam for supporting the latter on the arm, and means between said connection and the draft frame for automatically adjusting Copies of thispatent may bev obtained for the connection to raise and lower the plow beam upon the change in the angular relation between the draft frame and the plow beam.

2. The combination with a draft frame, a plow beam pivoted to the frame, and a plow point carried upon the beam, of an arm vertically slidable upon the beam, a wheel mounted on the lower end of the arm adapted to travel over the ground, a lever pivoted intermediate its ends upon said arm, a link connecting one end of the lever to the plow beam, and a connecting rod attached to the opposite end of the lever and to the draft frame for swinging the lever upon variation in the angular relation between the draft rame and the plow beam to move the arm ,vertically upon the latter and raise and lower the plow point.
