UNITED STATES PATENT OFFICE.
MICHAEL DEERING, OF SYRACUSE, NEl/V YORK, ASSIGNOR TO CHRISg TOPHER G. BRADLEY, OF SAME PLACE.
POWER-HAMMER.
SPECIFICATION forming part of Letters Patent No. 355,512, dated January 4, 18L'7.
Application filed October 16, 1886. Serial No. 216,417. (No model.)
Io'and it has for its object to produce a hammer which is adapted for rapid work, and which will deliver sharp blows in quick succession without heating.
My invention consists of the improvements I which will be hereinafter fully set forth, and
pointed out in the claims.
In the accompanying drawings, consisting of three sheets, Figure 1 is a side elevation of my improved hammer. Fig. 2 is a sectional 2o elevation of one of the rubber springs on an enlarged scale. Fig. 3 is a side elevation of the head portion of the hammer on an enlarged scale. Fig. 4 is a front elevation thereof. Fig. 5 isa top plan view thereof. Fig. 6 is a sectional elevation ofone ofthe spring-levers and connecting parts. Fig. 7 is a sectional elevation of the head portion of the hammer, show ing a modified arrangement of the spring-levers. Fig. 8 is a top plan view of said levers.
Fig. 9 is aside elevation of the hammer, showing another modified arrangement of the springlevers. Fig. 10 is a sectional elevation, on an enlarged scale, of the head portion of the hammer shown in Fig. 9. Fig. 11 is a 3 5 front elevation thereof. Fig. 12 is a top plan view thereof.
Like letters of reference refer to like parts in the several figures.
A represents the main frame of the hammer,
and a the anvil thereof.
B represents the hammer-head sliding between vertical ways I), formed on the main frame A.
0 represents the helve, which is pivoted to 5 the main frame at c, and which is operated from the driving-shaft d by a connecting-rod, D, in
any suitable manner.
E E represent two levers, pivoted to the front portion of the helve'by horizontal bolts e e, the levers being arranged between the two bars of which the front portion of the helve is composed.
F represents a strap or flexible connection, by which the lower ends of the levers E Eare connected with the upper end of the hammerhead B, whichlatterisprovided with an opening, f, through which the strap F passes.
Thelevers E E are arranged, respectively, in
front and in rear of the hammerhead B. The lower ends of the levers E E are bifurcated and provided with collars or sleeves 9. around which the strap F passes, and which are mounted on horizontal bolts 9, attached to said levers.
In the construction represented in Figs. 1, 3, 4, 5, and6 the upper arms, h h, of the levers E E are arranged horizontally and bear against the lower sides of two springs, I I. The arm h of the lever E extends rearwardly from the pivot e, and the arm h extends forwardly from the pivot e, The springs I I are arranged one behind the other above the helve, and are supported by bows or bridge-pieces H H, which are secured with their lower ends to the helve, and carry at their upper ends set-screws j j, by which the springs I I are adj usted. Each of the springs l I is provided at its upper end with -a metallic cup, J, against which the setscrew bears, and at its middle with a flanged metallic diaphragm, J, whereby the two portions of each spring are held against lateral displacement. Each springis preferably provided with a central aperture, in a well-known manner, to facilitate the operation of vulcanizing the rubber. By tightening the set-screws j j the levers E E are swung on their pivots, so as to tighten the strap F. Thesprings I I cushion the blow and enable the hammer to be operated at a high speed, delivering sharp blows in quick succession without heating, even when the'material between the hammer and anvil is very thin- -as, for instance, in
plating butcher and case knives. The cushextend past each other and bear against opposite sides of a single spring, K, which is interposed between the upwardly projecting ends of the upper arms, k 70. The latter are provided with set-screws Z l, which bear against opposite ends of the spring.
In the construction represented in Figs. 9, 10, 11, and 12 the upper arms, m m, of the levers E E project upwardly from their pivots, and two springs, M M, are arranged against the outer sides of the arms m m. These springs are connected by a horizontal screw-rod, n, which passes through the arms m m and the springs M M, and is provided on the outer sides of said springs with screw-nuts 0 0, whereby the levers and springs are adjusted.
I claim as my invention 1. The combination, with the helve and the hammerhead, of levers pivoted to the helve, and a flexible connection whereby said levers are connected with the hammer-head, substantially as set forth.
2. The combination, with the helve and the hammer-head, of levers pivoted to the helve, a flexible connection whereby said levers are connected with the hammer-head, and an elastic cushion applied to said levers, substantially as set forth.
3. The combination, with the helve and the hammer-head, of lovers pivoted to the helve, a flexible connection whereby said levers are connected with the hammer-head, and adjusting devices whereby the levers are adjusted, substantially as set forth.
4. The combination, with the helve and the hammer-head, of levers pivoted to the helve, a flexible connection whereby said levers are connected with the hammer-head, an elastic cushion applied to said levers, and adjusting devices whereby the levers and cushion ar adjusted, substantially as set forth.
5. The combination, with the helve and the hammer-head, of levers E E, pivoted to the helve, a flexible strap, F, connecting the lower ends with the hammer-head, springs I I, resting on the upper ends ofsaid levers, and bridgepieces H H, secured to the helve and support mg the upper ends of said springs, substantially as set forth.
. Witness my hand this 29th day of September, 1886.
MICHAEL DEERING.
