IMPROVEMENT IN ELASTIC HANGINGS FOR REVCLVING-HAMMERS.

Specification forming part of Letters Patent No. l 77,883, dated May 23, 1876; application tiled May 11, 1876.

To all 'whom t may concern:

Be it known that I', GoLDsBURY H. POND, of the city and State ot' New York, hav/ein# vent-ed a Ooncentric and Elastic Hanging for Revolving Hammers, Picks, Plows, Qutters, Beaters, Thrashers, the following is a specification:

The object of my invention is to provide all machines which give or receive a blow, or are liable to any jarring from the working parts, with elastic journal-boxes, and with springs to regulate the position of the working parts and keep them from breaking, by preventing thejar or the strain ot' the ing the main metallic parts of the machine, this being eectually accomplished by placing rubber springs aroundthe journals, and then bracing them up and holding them to their proper places by spiral and rubber springs. Revolving hammers thus tixed are practical and economical for breaking and pulverizing ores and stone, and there is hardly a limit to the Work of one of these machines when the hammers are, provided with the elastichanging. Without the elastic hanging the revolv.

ing hammers are worthless as rock-pulverizers, and have been known to break three out of the four hammer handles or Shanks made out of four-inch square Norway iron, in running twenty minutes. v

In the drawings, making a part of this speciiication, Figure l is a sectional view and Fig. 2 is a side and ing hammer E E. D is the pill upon which they swing. O is themetallic tube or ring on which the rubber spring B is placed, and then tted into the box A or outer ring. The box A is then placed in position in the mortise in the disks H H, and held there by the spiral spring G. The rubber springs F F are at- `tached to eachv heel or lower end of the hamand are drawn tight enough to mer-handle,

keep the heads of the hammers in a working position.

and Journals, ot' which blow from reach-- sectional view, of the revolv` The hammers move round to the die J, (whichis heldin place by the wedge M,) strike against it, swing in toward the center and pass over it, and so on, and any ores placedbet'ore the die are crushed and pulverized, and thrown out over the end ot' the machine.

The revol ving picks, steam cutters and plows, thrashing-machines, hemp and flax breakers, trip hammers, are all arranged in the same wayas the revolving hammers, with the addition, Where required, ot more disks` on the s ame shat't, and-provided with the same elastic hanging, which prevents them from breaking, thereby making the revolving steam-plow a complete success, and the quickest mode of preparing the iand for seeding, as well as the best and cheapest ever known; but which proved a failure for three successive years at Contra Costa, California, and the year following in the other western States, because the ground cutters or plows were iron and iron hangings and journals without elasticity.

. I do not claimv the revolving hammers as my invention.

What I claim as my invention is- 1. The concentric and elastic hanging for revolvingA hammers, picks, ground-cutters,

thrashing-machines, Src., as set. forth and de-l scribed.

2. The rubber spring around the journal of the pin on which the hammers, picks, and cutters swing, forming a part of the journal-box, to prevent the machine from breaking' by blows, jars, or concussion.

3. The spring from heel to heel ofthe hammer-handle or shank, across or to the center of the disks, or both combined, to keep the hammers, picks, cutters, thrashers, and beaters in a working position.
