` To all whom it may concer-n.'

Be it known that I, HENRY L. BARTON, a citizen of the United States, and a resident of the city of Gary, county of Lake and State of Indiana, have invented certain new and useful Improvements 1n Plows, of which forming a part of this specification, and in which- Figure 1 is a top plan view of a. grading machine equipped with a plow embodying my present invention,

Fig. 2, a side view of the same shown partially in section,

Fig. 3, an enlarged detail view of a. pointed shoe employed in the construction,

Fig. 4, an enlarged section taken on line 4-4 of Fig. 2,

Fig. 5, a detail view of an adjustable cross bar employed in the construction.

The preferred form of construction as illustrated in the drawings comprises a frame 6 mounted on Jfront wheels 7 and rear wheels 8. The front wheels 7 are loosely mounted in the ordinary manner on the front axle 9 and the rear wheels 8 are ixed to a rear axle 10 which is thus caused to rotate with the wheels. A gear 11 is fixed to the front axle 9 and meshes with a pinion 12 at the lower end of a shaft 13 which is provided with a handle 14 for steering the machine. A plow beam 15 is secured at its rear end to axle 10, said plow beam being provided with a knuckle joint 16 and a swivel joint 17 by means of which the beam may be swung vertically or laterally or may be twisted on a horizontal longitudinal axis. At its front end the beam 15 carries an ordinary plow share 18 and a stop chain 19 serves to limit the downward swing of the plow beam 15 and the depth of cut'of 'the plow. An adjusting chain 2O is also secured to the front of beam 15 and lisc'onnected with a. windlass 21 by means of which `plo-w 18 may be vertically adjusted' or may be entirely raised from'contact with the ground, as will be readily understood.

A transverse adjusting bar 22 1s pivotally connected at 23 to the beam 15 and extends transversely across the frame 6 passing slidably through a bracket'24 suspended on said frame. Bar 22 is provided with a plurality of holes 25 adapted to receive pins or bolts 26 and by means of which the lateral position ofthe bar may be adjusted in the bracket 24 'to control or adjust the lateral position of the plow 18. A brace 27 is pivotally connected at 28 with the plow beam 15 and is adjustably secured to the cross bar 22 by means of pins or bolts 29 npassing through perforations 30 as indicated; nBy,

this arrangement, the plow 18,1nay be tilted or angularly adjusted as desired. Y

' A pointed shoe 31 is secured to the lower ond of a bracket 32 depending from the'forward end of plow bea-1n 15 in position to irnmediately precede the plow 18 and serve as a means for breaking up the earth ahead of said plow to facilitate the action thereof.

' Pointed shoe 31 is provided with a socket 31 adapted to receive the lower end of the bracket 32 and with a lip 33 adapted to engage in a corresponding recess 1n said bracket, the two being secured-together by means of bolts 34 passing therethrough as shown.

A scraper or scoop 35 is arranged at the lower end of an elevator 36 leading to a discharge elevator' 37 thereon, said scraper, elevator and conveyor being arranged to cooperate with the plow 18 as will be readily understood. The scraper, elevator and conveyer constitute the subject matter of my prior application Serial No. 55,168, filed October 11th, 1915, referred to above and require no further description herewith.

A draft bar 38 is pivotally connected with a draft clevis 39 having a bolt and slot connection with the draft tongue 40 which is connected to the front axle 9 in the usual manner and by means of which the machine may be drawn by a traction engine or other suitable means. At its rear end the draft bar 38 is connected by means of a chain 41 with the bar 22 and by means of chains 42 ing from the spirit of the invention. I,

therefore, do not wish to be limited to the precise details of construction set forth, but desire to availmyselffof such variations and modifications as come within the scope of the appended claims.`

Havingdescribed my invention what I claim as new and desire to secure by Letters Patent is:

1. A grading machine comprising a wheeled ,frame having a rear axle; a plow beam mounted on said rear axleand extending forwardly therefrom; a knuckle jointron said rear axle permitting of lateral and verticalswinging of said plow beam; a swiveled joint for said plow beam permitting of tilting` thereof; a plow share'on said plow beam; and means for securing said plow beam in dierent lateral and tilted positions, substantially as described.

2. A grading machine comprising a wheeled frame havin a rear axle; aV plow beamzmounted on sai rear axle and extending forwardly therefrom; a knuckle joint on oftilting thereof; a plow share on said plow beam; means for limiting the downward swing of said plow beam; and adjustable means for securing said plow beam in differ-` ent lateral and tiltedpositions, substantially as described.

3. A grading machine comprising la wheeled 4frame `havincr a rear axle; a'plow beammountedonsai rear axle; a knuckle joint on said rearaxle permitting of lateral and vertical swinging thereof; a swiveled HENRY L. BARTON. Witnesses GEO. IM. MoRoBnRrs, el GREEN.
