JOHN FEGER, OF LENZBURG, ILLINOIS.

ROTARY COLTER.

PECIFICATION forming part of Letters Patent No. 340,301, dated April 20,1886. Application filed January 13, 1886. Serial No. 139,744. (No model.)

To aZZ whom it may concern.-

Be it known that 1, JOHN FEGER, of Lenzburg, in the county of St. Clair and State of Illinois, have invented a new and useful Improvement in Rotary Golters for Plows, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of my improvement shown as applied to a plow. Fig. 2 is a sectional front elevation of the improvement. Fig. 3 is an elevation of one part of the hubbox, showing its inner side, the wooden hub being shown in section. Fig. 4 is a side eleration of one of the annular washers.

The object of this invention is to provide rotary colters for plows,constructed in such a manner that the cutting-plates will be held securely in position, and that the parts subject to wear can be readily taken out and replaced by new ones.

The invention consists in the construction and combination of the various parts of the colter, as will be hereinafter fully described.

A represents the beam, 13 the mold-board, and G the landside, of an ordinary plow.

To the plow-beam A is secured, by a clamp, D, or other suitable means, the upper end of a standard, E, the lower end of which is forked to receive the hub-box F of the colter, and is perforated to receive the bolt G. The bolt G passes through the ends of the parts of the hub-box F, and has a head upon one end and a not upon the other end, so that it can be readily detached and replaced. I he parts of the hub-box F are made with annular flanges around their inner ends, and have their said inner ends recessed to receive the ends of the wooden hub H, which is perforated longitudinally to receive the bolt G. The wooden hub H is made square in cross-section, and passes through a square hole in the center of the cutting-plate I, so that the wooden hub will revolve upon the bolt G as the said cutterplate carries the said hub with it in its revolution.

Upon the inner sides of the annular flanges of the hub-box F are formed annular grooves J, to receive annular leather washers K and studs L, of a less length than the thickness of a the leather washers, to enter holes in the said leather washers and prevent them from turn- 5 5 ing upon their seats. M are annular metallic washersinterposed between the cutting-plate .l and the leather washers K, and-which have outwardlyprojecting flanges around their outer edges, to overlap the inner parts of the outer edges of the flanges of the hub-box F, to prevent sand and dust from working in. \Vith this construction the wooden hub H, when worn, can be readily replaced with a new hub at trifling expense.

Oil can be introduced into the interior of the hub-box through holes N, which can be closed by plugs or other suitable means to keep out dust.

Upon the ends of the hub-boar F are formed projections O, which strike against the standard E and hold the said hub-box from turn ng.

Having thus fully described my invention,

I claim as new and desire to secure by Letters Patent- 7 5 The combination, with the forked standard E, the bolt G, and the cutting-plate I, of the hub-box F, made in two parts, recessed at their inner ends, and having annular flanges around their said inner ends and projections 0 upon their outer ends, and having annular grooves J and studs L in the inner sides of their flanges, the square wooden hub H, placed upon the said bolt within the said hub-box, the annular leather washers K,placed in the grooves 8 of the said hub-box, and the annular flanged metallic washers M, interposed between the said leather washers and the, cutting-plate. substantially as herein shown and described.

JOHN FEGER.
