IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 141 ,375, dated July 29, 1873; application filed June 21,1673.

To all whom it may concern:

Be it known that I, CHARLES O. NASON, of city of Moline, in the county of Rock Island and State of Illinois, 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 pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to improvements in devices for regulating the depth of penetration of the plow; and the invention consists in a new and improved method of adjusting the distance between the forward end of the plow-beam and the gage-wheel, said device consisting of the jaw-plates of the clevis peculiarly constructed and a thumb-screw or similar device operating to clamp the forward arms of the metal bands which support the gage-wheel, all as hereinafter more fully set forth.

In the accompanying drawings, Figure 1 is a side elevation of the forward end of the plow-beam, showing the. adjustable gagewheel and device for clamping the same. Fig. 2 is a plan View, showing the peculiar construction of the jaw-plates of the clevis.

A represents the plow-beam. B B are the jaw-plates of the clevis, secured to the beam, one on each side, by means of a screw-bolt and nut, b, at their rear ends, and by a screwbolt and thumb-screw, O, at their forward ends, both bolts passing through the beams.

The forward ends of the jaw-plates are enlarged and widened and provided with a series of bolt-holes for adjustment of the clevis, as clearly shown in Fig. 1 of the drawings. The draft-hook is also made adjustable laterally, as shown by Fig. 2. But as these features of adjustment of the clevis do not form part of the invention claimed in this patent, no further or more particular description of them is deemed necessary.

On. the inner faces of the jaw-plates B recesses or grooves D are formed, as clearly shown by Fig. '2 of the drawing, forming, when the jaws are secured to the beam, open slots, somewhat arc-shaped and widened out at the lower ends, as shown by dotted lines in Fig. 1. E is the gage-wheel, journaled between two metal bands, F. The rear ends or arms of these bands F are pivoted to the plow-beam by a bolt, f, which passes through the beam.

The forward arms of the bands F are passed through the sockets D, between the jaw-plates of the clevis-and the plow-beam, and, being shaped like the arc of a circle, with the pivotbolt f as a center, they can be moved freely up and down within the sockets, thereby bringing the gage-wheel up nearer to or down further from the forward end of the plowbeam, as desired.

When the gage-wheel has been adjusted to the required height or distance from the plowbeam, it is secured in position by simply screwing up the thumb-screw 0, thereby clamping the clevis jaw-plates upon the arms of the bands F and the beam A.

A nut or any equivalent of the thumb-screw C may obviously be used, as found convenient or desirable.

By utilizing the clevis jaw-plates in the manner described, and by passing the free or forward ends or arms of the gage wheel through the arc-shaped sockets formed between the beam and the jaw-plates, it will be seen that the relative distance between the plow-beam and the gage-wheel can be readily adjusted without the use of any extrabolt or clamping device, and without the removal of any bolt, or any alteration of the adjusting device further than the unscrewing and screwing of the nut or thumbscrew on the forward bolt, thereby effecting a savingin the cost of construction, and producing a much more effeotive means of adjustment of the gagewheel than any heretofore in use.

When it is not desirable to use the gagebeam A, and thumb screw or nut O, for the purpose specified.

In testimony that I claim the foregoing I havehereunto set my hand this 9th day of June, 1873.

CHARLES O. NASON.
