DISK PLOW.

SPECIFICATION formingpart of Letters Patent No. 692,190, dated January 28, 1902.

Application filed September 3, 1901. Serial No. 74,224. (No model.)

My invention relates to improvements in' disk plows. 'It has in view to overcome certain objections or difficulties heretofore contended with, more especially in excluding r dirt, &c., from the bearings and in providing for the lubrication of the same.

It consists of the combination and arrangement of parts, substantially as hereinafter more fully disclosed, and specifically pointed out by the claims.

In the accompanying drawings, Figure 1 illustrates so much of a disk plow as is necessary to aid in the disclosure of my invention. Fig. 2 is a transverse section taken axially through the same. Fig. 3 is a similar longitudinal section. Fig. t is a detail perspective View of one of the disk clamp-plates, viewed from the inner side. Fig. 5 is a similar view of the opposed like part, also viewed from the inner side. Fig. 6 is a detailed perspective view of the rotary plow or cutter.

Fig. 7 is an end View of the plow-carrying axle or shaft. Fig. 8 is a detached section of one of theclamp-sections.

Latitude is allowed herein as to details, as they may be changed or varied at will without departing from the spirit of my invention and the same yet remain intact and be protected.

4o In carrying out my invention I suitably provide the usual hanger or beam 1, as employed in this class of plows, with a bearing or hub 2, having a tapered bore and preferably fixed or integral with a plate secured to said beam or hanger, said hub being arranged in the diagonal therein, as shown. In the ends of said hub or hearing are annular recesses 2 2, and upon the upper side of said hub is a lubricant-cup 3,whose chamber, however, extends into the area of said hub, having an opening 3 in its bottom, delivering lubricant I interiorly of said hub to an axle or shaft 4, turning therein, as presently described. A lateral opening 3, communicating with the interior of the chamber of thecup 3, delivers the lubricant to an enlargement of the axle, as also further referred to later on. Said cup is also furnished with a bored-out or hollow cover or cap 3 fitting lubricant and dust tight thereon. The axle or shaft 4, corre- 6o spondingly tapered with the bore of the hub or hearing 2, has at one end a reduced cylindric extension at, with a transverse opening 4 therethrough, and .upon said cylindric extension is screwed or fitted a nut 5, having a number of longitudinal slits 5, and through the slits, registering with the opening 4, is inserted a pin 6. Said axle has also near its larger end a stepped annular enlargement l with the greater diametered portion thereof housed or let into the annular recess 2 in one end of the hub or hearing 2, to which, as above intimated, is delivered or fed lubricant through the opening or passage 3. The axle or shaft 4 has outside of the less diametered portion of said enlargement a relatively reduced tubular or bored extension 4, having at opposite points upon its outer circumference lugs or projections 4:, terminating a short distance inward from the end of said extension, the purpose of which will be presently apparent. if The bore or chamber of said extension 4 extends into or penetrates the axle or shaft 4 some distance and has a screw-thread and receives a screw- 8 5 plug 6, again referred to later on.

A clamp disk or section 7 is slipped upon the bored extension 4? of the axle 4:, having an annular recess or countersink 7 in one side to correspond with and receive the less diam- 9o etered portion or shoulder of the enlargement 4: of said axle, and at opposite points in the edge of the passage through said clamp disk or section are notches or recesses 7" to receive the lugs or projections 45 of the tube extension 4t to prevent the turning of said disk or section. Said disk or section has also around the passage therethrou gh a raised or convexed surface 7., and indentingsaid surface at about or notches 7 the object of which will be presently seen.

equal intervals apart is a number of recesses Ico A disk plow or cutter S of the usual dished or concavo-eonvex construction is also slipped upon the tube or bored extension 4 of the axle. Said plow or cutter has also around the passage therethrough a central concavoconvex surface, with the concavity thereof presented next to the convexity of the clamp disk or section 7, and bent up orproduced in said concavity are ribs or projections 8, adapted to engage the notches or recesses 7 in said clamp-section to aid in effectively securing the same in position.

The screw-plug 6 has upon the inner surface of its head a shoulder 6, and slipped upon said plug is a second clamp-section 6 having a countersink or recess 9 around its passage or opening to receive said shoulder, makingatightjointbetweenthe parts. Upon the opposite side said clamp-section is slightly dished or concaved to conform to the convexity of the central concavo-convex portion of the plow, while also upon said dished surface of said clamp-section is a number of ribs or projections 9, engaging the notches or recesses 9 the converse of the ribs formed or bent up upon the opposite side of the plow, thus uniting with the previously-described clamp-section 7 to secure the plow in position upon the axle or shaft.

This invention provides for effectively excluding dust, &c., from the bearing and for the advantageous distribution of the lubricant thereto.

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

1. The combination of a plow carrying shaft oraxle, a clamp-section having opposite notches or recesses in its passage, engaging lugs on said axle, a plug engaging said shaft or axle, and a second clamp-section carried by said plug and having ribs engaging notches produced in the plow, substantially as set forth.

2. The combination of a plowcarrying shaft or axle, a clamp-section having opposite notches or recesses in its passage, engaging lugs on said axle, a plug engaging said shaft or axle, and a second clamp-section carried by said plug and having ribs engaging notches produced in the plow, one of said clam p-sections also having additional notches engaging ribs upon the plow, substantially as set forth.

3. The combination of a plow carrying shaft or axle, a clamp-section having opposite notches or recesses in its passage, engaging lugs on said axle, a plug engaging said shaft or axle, and a second clamp-section carried by said plug and having ribs engaging notches produced in. the plow, one of said clamp-sections having a convexed surface around its central passage, and additional notches produced in said convexed surface, substantially as set forth.

4. The combination of a plow carrying shaft or axle, a clamp-section having opposite notches or recesses in its passage, engaging lugs on said axle, a plug en aging said shaft or axle, and a second clamp-section carried by said plug and having ribs engaging notches produced in the plow and said clampsections having annular recesses around their passages, one adapted to receive a corresponding portion of said axle and the other adapted to receive a shoulder on the inner surface of said plug, substantially as set forth.

5. The combination of a plowcarrying shaft or axle, a clamp-section having opposite notches or recesses in its passage, engaging lugs on said axle, a plug engaging said shaft or axle, and a second clamp-section carried by said plug and having ribs engaging notches produced in the plow, and said shaft or axle having the tubular or bored extension and a diiferentlydiametered enlargement near its larger end partially housed in one of said clamp-sections, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

A. S. BAILEY.
