NITED STATES PAT NT OFFICE.
IMPROVEMENT IN POWER-HAMMERS.
Specification forming part of Letters Patent No. 52,894, dated February 27, N366.
brating a hammer and securing the die in the manner as hereinafter described.
In order to enable others to use and practice my invention, I will proceed to describe its construction and operation.
On reference to the accompanying drawings, which form a part of this specification, Figure 1 is a front .view. Fig. 2 is a vertical section on the line 1 and 2.
Similar letters refer to similar parts throughout the several views.
a is the anvil-block, secured to wood base I) by wood'screws.
c c are guide-rods extending up to cap 6, to which it is united by means of small screws, and at which point is formed the journal for shaft 1, for the purpose as hereinafter described. Said' guide-rods c c are secured to anvil a by means of screws d d.
an are two pillars supporting shaft m, to which is secured main driving-pulley 7c and crank 0, for the purpose of communicating power to the hammer through belt Z when said crank 0 is operated by the hand.
Shaft t has secured to it and carries flywheel g, counter-balance p, crank'disks h l1, and belt-wheel t, for the purpose as hereinafter described.
00 is a metal spring secured to rod '0, which enters hollow rod u, and to which it is secured by set-screw q. The upper end of hollow rod to has a split-box journal, 17, held together by screw 11, and grasps crank-pin s.
w is the hammer, secured on its upper end to belt 6 by wedge 8. Said belt is secured to spring a; by means of screws j j, all for the purpose as hereinafter described.
3 is a shield to prevent heat from burning the belt; z, the die secured to anvil a by means of wedge 4t and screw 5, as hereinafter described.
The hammer to can be made to strike high or low by means of lengthening or shortening rod o by screw 9. The weight of hammer can also be regulated by means of plug 2 being inserted into or taken from the hammer, which alters the weight in proportion. In order to prevent the plug from unscrewing itself pin 10 is inserted.
Spring w and belt 6, in combination with crank-pin and rod u, give the hammer a very free and elastic motion. It is also durable, as the belt is not aifected by the sudden ,vibrating of the hammer.
W'edge 4 secures die 2 by being forced under it by means of screw 5.
The object of counter-balance p is to lift the hammer off the anvil-block when stopping.
This can also be effected by means of a spring THOMAS SHAW. pus
