Description
JAY H. BROWN, OF GRAND LEDGE, MICHIGAN.
MACHINE FOR PUNCHING METAL.
Specification of Letters Patent No. 24,191, dated May 31, 1859.
To all whom it may concerm Be it known that I, JAY H. BRowN,'of Grand Ledge, in the county of Eaton and State of Michigan, have invented a new and useful Improvement in Machines for Punching Metals; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l is a perspective view. FiO'. 2 is a detached vertical section. Fig. 3 is a plan of the head of the punching bar.
Similar letters indicate corresponding parts.
The frame of this machine is of iron, cast all in one piece. It consists of a standard A of suiiicient solidity and strength, with a platform at the bottom, which projects beyond the sides and front, and provided with a die box of any ordinary construction. The upper end of this standard is arched to project opposite the platform and has two stout brackets B, B, cast on it, one on each side; an arm C is also cast on its edge at a proper height, which has a bearing at the end marked D to receive the punching bar E. This bar is made ordinarily of cast iron, with strong flanges around the top forming a solid circular head marked F, and is usually banded with wrought iron where t-he punching tools are inserted at the lower end. The bar E is left free to move up or down in its bearing in the arm C, but is prevented from turning by a tongue in the bearing, working in a groove in the bar. Or the bearing may be four square and the bar E also to eect the same purpose.
The upper end of the bar E is bored out to receive a rod G to which it is connected by a check pin below the head F. The rod Gr is usually of wrought iron, and may be much lighter than the bar E, to which it is attached; it passes through a bearing in the upper projecting end of the standard, far enough to receive a stiff spiral spring S.
L is a lever which is intended to be operated by hand; it has a head M which nearly corresponds in size and form with F, and is bored out in the center so that it may fit the rod Gr and turn freely round it.
A series of rollers O, O, O, &c., which are frustums of cones, of cast metal, are interposed between the upper side of F and the under side of M. These rollers are conned in place by resting in a groove, so as to ll and occupy it, but not tightly in contact with it, and each other as more clearly shown in Fig. 3.
rlhe large or outer ends of the rollers are rounded to a circle of the same radius as the circle they form when arranged in place; and the convexity of the two contact faces of F, M, as well as the taper of the said rollers, are determined by lines which intersect at the center.
I, I are extension bars with steeled ends of spherical form, which ends are inserted in sockets of a suitable corresponding form, two in the movable lever head M, and two in the under side of the stationary brackets B, B in such manner that when the lever is in line with the frame, the bars will stand vertical and at an equal distance from the rod Gr.
When the lever is moved around in either direction from this position, it carries with it the lower ends of the bars I, I, and the spring S acting on the rod G draws up the punching bar to an extent equal to the shortening of said bars by the angle of inclination to which they are thrown, which is regulated by two stops, opposite the lever arm, one'of which is seen at J.
The mode of operating this machine is by simply moving around the lever L, 'from either stop, to the position rst described, when the. bars I, I, will assume a vertical position and drive down the punch. The frustoV conical rollers, by rotating when they take the power., prevent injurious friction, and
obviate the dililcultyof keeping flat rubbing surfaces in such a position, thoroughly lubricated when subjected toheavy pressure.
This machine is more especially adapt-ed for the use of those who are precluded from using the more elaborateand costly kinds, as it consists of very few parts, and is of simple construction, and-give sufficient power and travel for the ordinary work of country shops, such as punching holes, gumming saws and other analogous uses in the working of metals, for which it is adapted.
I know very well that the moving a rigid bar, by the aid of both simple and compound levers, from an oblique to a straight and parallel position; in order to produce a powerful pressure, is not new, and that ink inot claim broadly the extension bars I, I,
los
for producing pressure generally when used l for the purposes specified; the Whole being in the manner described; but constructed and arranged, substantially in 10 What I do lolaiIiJn as ing invention and dethe manner as herein described and set forth. sire to secure y etters atent, is* l 1 5 The application and use of the bars I, I, JAY H' BROWB" l in combination with the lever- L, punching Y Witnesses: bar E, frusto conical rollers O, O, O, O, &o., NATHAN CHIDESTER, rod Gr and spiral (or equivalent) spring S, GEORGE JOHNSON.
