AUGUST NELSON, OF KENT, OHIO.

BUSH-HAMMER.

SPECIFICATION forming part of Letters Patent No. 328,509, dated October 20, 1885.

Application filed July 6, 1885.

To all whom it may concern:

Be it known that 1, AUGUST NELsoN, a citizen of the United States, residing at Kent, in the county of Portage and State of Ohio, have invented a new and useful Improvement in Bush-Hammers, of which the following is a specification.

My invention has relation to improvements in that class of bushhammers in which the points are removable and can be renewed when worn.

The objects of my invention are to impart to the points the same solidity as if integral with the head, to afford facilities by which the points can be readily and rapidly changed, and to provide devices for clamping the points to the head and for taking up wear.

My invention consists in the devices illustrated in the accompanying drawings, as hereinafter described, and specifically pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation; Fig. 2, afront elevation; Fig. 3, a section of Fig. 2 at the line 00 00,- Fig. 4., a plan of either end.

The head A, of metal, is in the ordinary form of a two-faced hammer, having an eye, a, for the handle, and with each end face plane.

Two caps, B B, fit over the faces of the head A, side wings projecting along the sides of the head, and are held by draw-bolts O G. Each bolt 0 has a round body of even diameter, with one end screw-threaded and the other enlarged conically. A conical nut, c, fits the threaded end. These bolts pass through holes in the wings of each cap B and in the head A, the holes in the wings and the ends of the holes in the head being countersunk to fit the conical ends of the bolt and nut, the hole in the head being slotted to permit a lateral movement of the bolt.

Serial No. 170,701. (No model.)

The face of each cap is perforated with a series of holes, I) 1), arranged substantially as the points of a bush-hammer, and maybe slightly countersunk on the inner face. these holes is placed a pin, it, preferably diamondpointed, and havinga flange or enlargement at the other end.

In operation pins are placed in each of said holes, the cap is then placed on the end of the head, and by the draw-bolt firmly attached. The pins thus rest against the face of the head, which afiords them a firm base, and are rigidly held in place by the cap and draw-bolt.

If by use the points become so worn as not to press against the head they can be at once tightened by turning the nut 0.

I claim 1. Abush-hammer consisting of ahead with a smooth face, and a perforated cap fitting over said face and attached to said head, having pins in said perforations which rest against said face and project beyond said cap, substantially as and for the purpose hereinbefore set forth.

2. In a bushhammer, the combination of a head with a plane face, a perforated cap fitting over said face, a series of pins which rest in said perforations with one end against said face and the other projecting beyond said cap, and a draw-nut passing through said cap and head, substantially as and for the purpose hereinbefore set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 24th day of June, A. D. 1885.

AUGUST NELSON.
