LYMAN KIN SLEY, CAMBRIDGEPORT, MASSACHUSETTS.
IMPROVEMENT IN TRlP-HAMMERS.
T0 at whom. it may concern:
Be it known that I, LYMAN KINSLEY, of Cambridgeport, in the county of Middlesex and- State of Massachusetts, have invented certain new and useful Improvements in Trip- Hammers; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which-- Figure 1 is a side sectional view of my in-' vention, taken in the line a: m, Fig. 2. Fig. 2 is a plan or top viewof the same; Fig. 3, a transverse vertical section of the same, taken in the line 3; 3 Fig. 2.
Similar letters of reference indicate corresponding parts in the several figures.
A The invention consists in a novel arrangement of the anvil-block, whereby the anvil may be readily adjusted to compensate for wear, and also to suit the taper designed to be given to the work.
To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.
A represents a bed-plate, on which the triphammer is placed, and B B are two parallel bars secured to the bed-plate and having bearings G G on them, in which a driving-shaft, D, is fitted. This shaft D is provided at one end with a fly-wheeL-E, and with projections or tappets a at its center. The bearings G O are so arranged that they may be adjusted longitudinally on the bars B B. Between the inner parts of the bars B B there are secured transversely two parallel plates, F F, the upper surfaces of which are hollowed out in semicircular. form, as shown clearly in Fig. 3 and G is a semicircular plate which is fitted on the plates F F, and is provided with pendent flanges a,to serve as guides, said flanges extending down at the inner sides of the plates F, as shown clearly in Fig. 1. At each end of the semicircular plate G there is a box, H, in which bearings I are placed and adjusted by set-screws a. Through each bearing I there passes two screw-rods, J J. These rods pass down through the bottoms of the boxes H H, and also pass through metal plates K, .which bear against the under sides of lips or projections b at the inner sides of the bars BB, as shown in Fig. 3, the lower ends of the screw-rods J being provided with heads a*. On the upper ends of the screw-rods J there are placed nuts 0, as shown in all the figures.
In the bearings I I there are fitted the trunnions or journals d d of a clamp. L, in which a bar,'M, is secured. This bar M has the hammer N attached to its under surface, near its outer end, and the inner end of the bar has a projecting lip or plate, 0, against which the projections or tappets a strike as the shaft D rotates and elevate the hammer N.
P represents an anvil, which is fitted on the top of a block, Q,in the usual or in any proper way. This block Q has a concave recess, e, made in its under surface, and this recess is fitted on a corresponding convex surface, f, on a plate, R, which is raised atrifle above the bed-plate A, as shown in Fig. 1. The anvilblock Q is secured in position by screwbolts g, which pass through the plateR and a flange, k, at the lower part of the anvil-block, one near each corner or angle, as shown in Fig. 2.
From the above description it will be seen that the anvil-block Q may, by adjusting the screw-bolts g, be placed either in a vertical position or in an inclined position either forward or backward, so as to give the anvil P a horizontal position or a more or less inclined one; and it will also be seen that the semicircular plate G may, by turning the nuts 0, be adjusted on the plates F F, so that the hammer bar M will be turned to give the face of the ham Iner N a more or less oblique position. By this adjustmentlof the hammer and anvil the bar to be operated upon may be drawn out in taper form and with a greater orless degree of taper, as desired, without the troubio of wedging either the anvil or hammer, and one hammer is made to answer for all the different tapers.
This invention also admits of the anvil being adjusted to compensate for wear, for if one tion of a sphere, the recess 6 corresponding to The anvil-block Q, arranged, substantially the same. as sh0wn, on a plate, R, to admit 'of the ad- I do not claim the manner of adjusting the justment of the anvil P, as described. 45
hammer-bar M, as herein described, for that has been previously done; but, 'LYMAN KINSLEY' Having thus described myinvention, whatI Witnesses:
claim as new, and desire to secure by Letters BENJ'. F. SWEET,
Patent, is- SAMUEL H. RANDALL.
