UNITED STATEs PATENT OEEIoE MATTHEW VON G'ULIN, OF BALTIMORE, MARYLAND.
IMPROVEMENT IN MACHINES FOR STRlKING UP SHEET-METAL.
Specification forming part of Letters Patent N0.147,806, dated February 24, 1874; application filed December 23, 1873.
To all whom it may concern:
Be it known that I, MATTHEW VON CULIN, of Baltimore city, State of Maryland, have invented an Improved PressingMachine, of which the following is a specification:
My invention consists, first, in the combination of the follower, that carries the blank-' holder, with the reciprocating cross-head, by means of bolts connected to the follower by ball-and-soeket joints; and, secondly, in the combination, with the cross-head and plunger, ot' the cam and crank pin, as hereinafter more clearly set forth.
Figure 1 represents a front view of my im- Fig. 2 is a back view; Fig. :3, a side view. Figs. 4, 5, and 6,. represent detached views of the cam and ball-and-sockct joints.
A, in Figs. 1, 2, and 3, represents the framework and bed of my machine. Z, Fig. 2, is the driving-pulley; V, the driving-shaft; \V, the endless screw which gives motion to the gear-wheel T, which drives the cam D. -(See .l igs. 1 and 3.) The cam D operates on an anti-friction roller', J, which is carried by lugs on the cross-head K. Said cross-head has long tight bearings B B, and carries two bolts running vertically through it, and adjustable thereto by means of nuts on the top and bottom of the cross-head, the other ends of the bolts being attached to the follower H by the ball-and-socket joints S S, of which Fig. 4 is a vertical section. a a, b b, and h, Fig. 1, represent a vertical section of the die, blankholder, and plunger. 0 e is the holding-surface of the die, and 0 0 the holding-surface of the blank-holder h, the plunger. The holdingsurface of the die and diameter of the blank it being the same, the blank must of its own and flaring sides of the die. The follower H runs sufficiently loose in the guides B B to allow the blank-holder to adjust itself to the blank by means of the ball-and-socket joints S S and tapering sides of the blank-holder a a with the flaring sides of the die II b. The antifriction roller is held in position against the cam by means of springs, levers, or other suitable means. The crank-pin f, Fig. 1, is set opposite the center, N, Figs. 1, 5, and 6, of the circular part of the cam, from L to L. The yoke c, and arm J which carries the plunger, are given a reciprocating motion by the crank-pin f, which travels from c to c, in the slots y 3 as the cam revolves. The holes cl, g, and In, Fig. 6, or the slot M, Fig. 5, (or by keying the cam 0r crank off a common center in other machines not here described,) are for moving the crank-pin 0d the center N. The
plunger It continues its downward motion, after the blank-holder (t strikes the blank, a proportionally longer stroke being given if I move the crank-pin foff the center N thus enabling me to press a deeper piece in proportion to the throw of the press than has yet been accomplished. The arm J' is guided by a groove in cross'head K and a cap, F.
VhatI claim, and desire to secure by Letters and plunger J, of the cam D, and adjustable crank-pinf, as specified.
MATTHEW VON CULIN.
