UNITED STATES PATENT OFFICE.-
EDWARD O. HIGGINS, OF FAIRHAVEN, MASSACHUSETTS.
IMPROVEMENT IN MACHINES FOR PUNCHING SHEET-METAL TUBIN G.
Specification forming part of Letters Patent No. 200,454, dated February 19, 1876; application filed October 22, 1877.
To all whom it may concern:
Be it known that I, EDWARD O. Hrcenvs of Fairhaven, in the county of Bristol, State of Massachusetts, have invented a new and useful device for punching with one movement stove-piping and cylinders of sheet metal, so as to receive dampers, stop-cocks, &c., which device is fully described in the following specification and illustrated in the accompanying drawing.
Figure I is a general view. Fig. II is a sectional view of the working part.
The device consists of arms A, B, and C (see Fig. I) and standard D, secured laterally to the work-bench by shoulder E. The cutter or upper punch F is secured to the upper arm A by plate Gr and screw-bolt H. The cutter or lower punch I is secured to the lower arm 0 by the plate J, and is secured to standard K by a screw marked R. (See Fig.2.) Standard K moves freely in cylindrical socket L, and is temporarily secured by pin M, fitting in holes marked .9 s sin Fig. II. The adjustment of standard K in socket L increases or diminishes the distance between arms B and O, and
adapts the device to cylinders and piping of various dimensions.
The arms A, B, and O are of steel, and when not in use the arm A rests upon arm B.
The cylinder or piping is placed over arms B and O, the upper portion being between arms A and B, and the lower portion between arms (3 and D, the punchF being on the outside, and the punch I on the inside, of the cylinder or piping.
The punches are operated bya stroke of the hammer upon bolt H.
I claim- For the purpose of punching with one movement both sides of a cylinder or piping of sheet metal at points diametrically opposite each other, the combination of arms A, B, and C and arm or standard D, secured to the workbench by shoulder E, as set forth, together with punches F and I.
EDWARD O. HIGGINS.
