COLTER ATTACHMENT FOR PLOWS.

Specification of Letters Patent.

Patented Dec. 12, 1905.

Application filed August 16, 1905. Serial No. 274,431.

To all whmn it may concern:

Be it known that I, HOLLES A. MOQUILLIN, a citizen of the United States, residing at Wau seon, in the county of Fulton and State of Ohio, have invented a new and useful Colter Attachment for Plows, of which the following'is a specification.

This invention relates to plows, and has for its object to improve the construction and increase the efiiciency of the supporting and adjusting mechanism of the disk-jointer or colter devices of implements of this character.

Another object of the invention is to provide asimply-constructed and easily-applied device whereby the disk cutter may be adjusted in all directions relative to the beam or moldboard and firmly supported in any of its adjusted positions.

With these and other objects in view, which will appear as the nature of the invention is better understood, the same consists in certain novel features of construction, as hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which corresponding parts are denoted by like designating characters,is illustrated the preferred form or embodiment of the invention capable of carrying the same into practical operation.

In the drawings, Figure 1 is a side elevation, and Fig. 2 is a'plan view, of a plow with the improvement applied. Fig. 3 is an enlarged sectional detail of the improved device detached, and Fig. 4 is a sectional detail of the beam-clamp portion of the device.

The improved device may be attached to any of the various forms of plow-beams in use and operative with any of the various sizes and forms of moldboards, but for the purpose of illustration is shown applied to an ordinary steel beam-plow in which the beam 10, moldboard 11, and share 12 are of the usual form.

The improved device herein shown and described consists of a standard 13, threaded at the upper end and with an intermediate offset 15, as shown. Bearing above and below the beam 10 are two rods 16 17 having eyes 18 19 at one end for receiving the standard 13 and with the opposite ends threaded and carrying nuts 20 21, supportinga clamp-plate 22 against the opposite side of the beam, the standard 13 being thus firmly clamped adjustably to the beam. The threaded end of the standard is provided with a clamp-nut 23, bearing upon the upper eye 18 of the rod 16 and firmly supporting the standard from downward movement, while at the same time permitting vertical adjustment thereto. EXtending laterally of the lower part of the standard 13 is an arm 24, threaded at one end, as at 25, and forked at the opposite end, as at 26 27 the forked portions with threaded terminals, as at 28 29. A lateral shoulder or collar 30 is arranged upon the member 24 between the forked portion and the body of the member. The forked portions 26 27 embrace the main standard 13, and the latter is clamped in position between the forks by a clamp-plate 31 and clamp-nuts 32 33, as shown in Fig. 3. The standard is thus firmly compressed into the wedge-shaped cavity between the forked portions and rigidly coupled in place, while at the same time the arm is readily adjusted in position upon the standard when required.

The cutting-disk 34, in dishing form, as

shown, is rotatively mounted upon the arm 24 and bears against the shoulder 30 and is clamped in position by binding-nuts 35 36 upon the threaded end 25 of the arm. Rotative upon the arm 24, between the nuts 35 36, is a scraper-standard 37 the nuts thus serving the twofold purpose of means for holding the cutter-disk and the scraper-standard in place.

'Rotatively adjustable upon the standard 37 is a scraper-blade 38, preferably formed by bending a sheet of metal around the standard and securing in place by a clamp-screw 39. The free end of the plate 38 is sharpened and bears against the inner face of the cutter member 34 and removes all adhering earth or other material therefrom as the cutter rotates against the scraper. The standard member 37 and scraper 38 are thus adjustable relative to the cutter-disk, so that the scraper may be adjusted to perform the required action in a satisfactory manner.

The parts are simple in construction, can be readily applied to the plow, and adjusted to any required extent.

Having thus described the invention, what is claimed is 1. In a plow, astandard depending from the beam, an arm extending transversely of said standard and carrying a cutting-disk at one end and with the other end forked to embrace the standard and with forked portions of the arm threaded, a clamp-plate carried by said threaded portions and bearing against said standard and clamp nuts carried by said threaded portion and bearing against said plate.

2. In aplow, a standard depending from the beam, an arm extending transversely of said standard, and with a lateral shoulder intermediate the ends and with one end threaded and the other end forked for embracing said standard, the terminals of the forked portions being likewise threaded, a clamp-plate carried by said forked portions and bearing against said standard, clamp nuts carried by said forked portions and bearing against said plate, a cutting-disk carried by said arm and bearing against said shoulder, and clamp-nuts upon the arm in advance of the disk and bearing upon the same.

3. In a plow, a standard depending from the beam, an arm extending transversely of said standard means for adjustably coupling said arm to said standard, a cutting-disk mounted for rotation upon said arm, a standard carried by said arm and bearing upon the disk-supporting members, a scraper adjustably connected to said arm-standard andengaging said disk-supporting members, and aclamp-nut operating upon said arm and bearing upon said arm-standard.

4:. In a plow the combination of a draftbeam, a vertical standard having the upper end threaded and extending above and below the draft-beam, rods having eyes at one end for engaging said standard above and below the draft-beam and with the opposite ends threaded, a clamp-plate engaging said rods and bearing upon the opposite side of the draft-beam, clamp-nuts operating on said rods and bearing upon said plate, and a clamp-nut upon said standard and bearing upon the adjacent rod.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two Witnesses.
