i UNITED STATES PATENT OFFICE.
SAMUEL DAVIS, OF MIFELIN, PENNSYLVANIA.
MACHINE FOR PUNCHING SHEETIRON FOR MANUFACTURING STOVEPIPES AND OTHER PURPOSES.
Specification of Letters Patent No. 1,495, dated February 21, 1840.
To all t0/tom it may concern Be it known that I, SAMUEL Davis, of the town of Mifliin, in the county of Juniata and State of Pennsylvania, have invent-ed an improvement in the manner of constructing machines for punching sheetiron to admit the rivets in the manufacturing of stovepipes and for other purposes; and I do hereby declare that the following is a full and exact description thereof.
Figure l, isv a side, and Fig. 2, an end, view of my machine, the bed and frame of which I make of cast-iron.
A, A, is the bed, or basis, of the machine; B, B, the ends, and C, C, two connecting cheek pieces connecting the two ends, and sustaining the fulcra of the main lever and the cams. In Fig. 1,one ofthese cheek pieces is removed for the purpose of showing the manner in which the lever and cams are a-rranged.
a, a, a, are dies iXed in place by the thumb screws Z), l), I). To these dis are adapted steel punches c, c, c: The two end punches c, c", I pass through holes in two guide pieces CZ, (Z, which serve to steady the slide as it moves up and down.
D, D, is the slide which holds the punches c, c, c, affixed in its lower side by the screws e, e, e. The ends of the slide are furnished with tongues which enter the grooves f, f, in the end pieces. Then not borne down by the lever, the slide is raised by spiral springs contained in the boxes E, E, or by springs acting in any convenient way.
Two cams F, F, work on fulcra G, Gr, sustained by the cheek piecesy C, C. These cams are halved together at their upper sides g, g, so that the bearing piece H, which is intermediate between them andthe lever,
machine, and turned up and down by means of the winch K. It is represented in the drawing as turned up, but when the winch is brought around a quadrant of a circle it will rest against the punched plate and keep it from rising as the punches are withdrawn.
Having thus fully described the manner in which I construct and use my machine for punching a row of holes, simultaneously in a metallic plate, what I claim as my invention therein, and desire to secure by Letters Patent, is-
The mode in which I have combined the whole together so as to produce the intended effect, that is to say, I do not claim the punches, or dies, or either of the parts described taken individually; but I do claim the particular manner in which I have combined, and arranged, the main lever I, they bearing piece H, the ca-ms F, F, and the check plate J, J, so as to perform their respective offices, substantially as herein set .-forth.
SAMUEL DAVIS.
