SPECIFICATION forming part of Letters Patent N 0. 682,587, dated-September 10, 1901. I

Application filed July 16, 1901. Serial No. 68,510. No model.)

To (LZZ whmn/ it may concern:

Be itknown that I, OALVINR. DAVIS, a resident of South Bend,in the countyof St. Joseph and State of Indiana, have invented certain new and useful Improvements in Flows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. My invention relates to an improvement in plows, and more particularly to an improved gage or guide wheel therefor, the object of the invention being to provide an improved guidewheel and so mount the same as to cause the t5 plow to run true and steady and prevent vibration and which can be adjusted to various angles to suit the conditions of the soil.

With this object in view the invention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter described, and pointed out inthe claims.

In the accompanying drawings, Figure 1 is a View in elevation, illustrating my improve- 2 5 ments. Fig. 2 is a rear view, partly in section; and Fig. 3 is a detail View in section.

1 represents a metal beam curved downward at its rear end, forming the standard A, and then extends forward in the form of an 0 elongated foot, contracted for the attachment of the landside 2, and suitable handles 3 are secured to the beam, as shown. The standard A and beam 1 are made on their opposite faces with flanges 4 at each edge and a cen- 3 5 tral depression 5, and a disk-spindle box 6 is secured. to the standard and has mounted therein a spindle to which the rotary disk moldboard 7 is secured.

'A casting 8 is secured on the standard A above the disk-spindle box by means of a bolt 9 and is made with grooves and ribs on one side to receive the flanges 4 on the standard and prevent movement of the casting when secured in place by the bolt. The other 5 or outer face of the casting 8 is made with parallel flanges 10, between which a rod or wheel standard 11 is secured by means of a 1 bolt 12, together wit-h bolt 9, above referred to, and said casting is enlarged between the bolt-holes to permit the relative angle of the standard 11 to be changed by simply loosening one bolt and tightening up the other, the enlarged central portion of the casting between the bolt-holes serving as a fulcrum on which the standard moves. The standard 11 is bent, as shown, and has secured thereto a scraper 13 (for the guide-wheel 14) by a bolt 16, which latter also serves to secure one end of abrace-rod 17 to the standard 11, the other end of said rod 17 being bent and passed through one handle3 and screw-threaded on its end for the reception of a nut to secure the brace in position. The loweror rear end of standardll is widened and made near each side edge with a hole, alining with holes in a tongue 18, integral with and projecting at right angles to a spindle-box 19, which is made with a slightly-conical bore to receive a similarly-shaped spindle 20, integral with a plate 21, secured to the guide-wheel 14 by bolts, as shown, and said plate is made with a circular flange 22 to inclose the end of box 19 and prevent the entrance of dirt and grit therein. Said spindle 20 is made with a central hole for the reception of a bolt 23, on which latter a washer 24 is located and held in the enlarged and flanged end of the box by a nut 25 to secure the spindle therein. The tongue 18 is made thickest at its center be-- tween the bolt-holes and slopes or inclines to its edges to permit the relative angle of the tongue and box 19 to be changed by simply loosening one bolt and tightening the other, as the central or widest portion of the tongue will serve as a fulcrum on which the tongue is turned to change the angle of the guidewheel, as will be readily understood. This guide-wheel 14 runs in the corner of the furrow and lessens the friction of the soil on the landside shoe, also causing the plow to run steady.

The guide-Wheel is made With an oval face, or, in other words, a rounded periphery, which sinks a short Way into 'the soil, forming a hold for the wheel and preventing the 5 plow vibrating to either side, thus insuring a straight and even furrow. Besides, itis found by practice that the oval-face rim sheds the soil more readily than other forms of face.

It is important that the relative angle of too the wheel-standard to the plow-standard and the guide-wheel to the Wheel-standard can be adjusted, for the plow has a tendency in some soils to Work away from the wall of the furrow, and the wheel can, by the means above described, be set at the proper angle to cause the plow to run true.

Various slight changes might be resorted to in the general form and arrangement of the several parts described without departing from the spirit and scope of my invention, and hence I would have it understood that I do not wish to limit myself to the precise details set forth, but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of my invention.

I do not in this case claim the general features of the plow, the same being covered by the claims of my application filed April 29, 1901, Serial No. 58,020.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a plow, the combination with a standard, of a rotatively-mounted moldboard on said standard, a wheel-standard projecting rearward from the plow-standard, means for adjustablyconnecting the wheel-standard to the plow-standard, and a wheel adjustably supported by said wheel-standard behind the cured to the casting by bolts on opposite sides of the raised portion, a wheel-spindle box, a tongue thereon raised or enlarged between its side edges, bolts on opposite sides of said raised portion securing the tongue and wheelstandard together, and a guide-wheel rotatively supported in said box.

3. In a plow, the combination with a standard, a moldboard, a landside and a point connected with said standard, of a wheel-standard secured to the plow-standard and projecting rearward therefrom, a guide-wheel rotatively supported at the rear end of the wheelstandard and means for changing the angle of the wheel with relation to the Wheel-standard and means for changing the angle of the wheel standard with relation to the plowstandard.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

CALVIN R. DAVIS.
