Description

UNITE SAIIES PATENT FFICE.
DANL. NEWTON, OF SOUTHINGTON, CONNECTICUT.
SHEARS FOR CUTTING SHEET .METAL Speccaton of Letters Patent No. 22,028, dated November 9, 1858.
To all whom it may concern:
Be it known that I, DANIEL NEWTON, of Southington, in the county of Hartford and Stato of Connecticut, have invented several new and useful Improvements for Circular Shears for Cutting Sheet Metal; and I do hereby declare that the following is a full and exact description thereof, reference being had4 to the accompanying drawings and to the letters of reference marked thereon.
The nature of my invention consists in the application of one or more of the following improvements to shears for the circular cutting of sheet metal; viz., lst, cutters with holes through them revolving on a rod or axle; 2d, a spring to hold said cut-ters together; 3d, a screw to hold the metal; 4th, a spring-gage on which the metal rests when placed in the machine.
To enable others skilled in the art to make and use my invention I will proceed to describe its construction and operation.
rIhe frame or body of the shears can be made of any form or size to suit the owner without affecting the application of my improvements. The following form is the one I now use. I make a frame of cast iron containing t posts in front and one in the rear as shown at A in the accompanying drawings the middle front posts about two inches between them; in the upper ends of the front posts are hung 2 arbors, B B, the ends coming together between the two center posts, with collars, or flanges on them to hold the metal while cutting. arbor is a crank C to operate the machine. Against the end of the left hand arbor is a screw I), by which the pressure is .regulated on the metal. Attached to the left hand middle post is a spring gage E on which the metal rests when placed in the machine. It is secured by a set screw; the pin turning about 90 degrees in the first quarter of the circle, and is instantly returned to its place by the aid of a spiral spring attached to the same; it is also raised and lowered at pleasure, to meet the required size. Attached to the two center posts and the rear post, are 2 rods F F on which are placed 2 cutters, C C. One has a frame extending about half around it in which is a set screw to hold it in place, the other is held to the iirst by a spring secured by collar and set screw; the cutters I make from 2 to 3 inches in diameter, and about 2 inch bearing on the rod, being movable at pleasure to meet the required circle.
That I claim as my invention, and desire to secure by Letters Patent is- The application to circular shears, of two rods, with a revolving cutter on each rod, sliding either way, to adjust the size of the circle.
DANIEL NEWTON.
