UNITED .STATESv PATENT i OFFICE.
PETER BAUER, OF NEWARK, NEW JERSEY.4
IMPROVED SPRING-PUNCH.`
To all whom t't may concern:
Be it known that I, PETER BAUER, of Newark, in the county of Essex and State of New Jersey, have invented a new and Improved Sprin g-Punch; and l do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure lis a side elevation of this invention. Fig. 2 is a detached face view of a revolving head carrying the punches and headin g-tools. y
Similar letters of reference indicate like parts.
This invention relates to a tool for punching holes ot'dift'erentsizes into leather, paper, or any other substance or material of a similar nature, and for inserting and heading eyelets. The punches are secured in ahead which revolves between the two arms or prongs ot' one ofthe jaws of a pair of nippers on a `pivot which has a firm bearing on both sides ot' the punch-head, and which at the saine time forms a guide for the springcatch, which serves to retain said head in the desired position. The other jaw carries a block or anvil, which is secured to it by a thumbserew, so that it can be revolved and set in any desired position. lt is provided With several faces, one of which is covered with sheet-brass or other soft metal, to be used for punching, while the other faces are provided with holes and recesses to correspond to the pins and faces of the heading-tools.
My tool consists of a pair ot' handles or shanks, A B, which are connected by apivot, a, where they cross each other like nippers or shears. That portion ot' the shank B which extends beyond the pivot forms the arm B', that supports the head O. The arm B is forked, and its two prongs or jaws straddle the head and form the bearings for the center pin, bv This pin, being supported on both sides ofthe head, is capable to resist all the pressure to which it may be exposed, and it is not liable `to Work loose, whereas it' the pin projects from the side of the arm and is supported only ou one side of the head it is liable to work loose or to bend and break.
The head G carries three (more or less) punches, c, of` different sizes, and an unequal number of heading-tools, e', of corresponding size, and these punches and heading-tools are firmly secnredin the circumference ofthe head, as clearly shown inthe drawings. By turning the head on the center pin either ofthe punches or heading-to0ls can be brought in operation, and the head is heldin the desired position by a spring-catch, D, which drops into a series ot' cavities, d, on the side of the head. This springcatch is secured to the arm by means of a screw, e, and it is provided with a socket, e', which drops over the end ot' the center pin. By this arrangement said springcatch is prevented from shitting, and it is enabled to retain the head O in the proper position for either of the tools connected therewith.
E is the anvil against which the punches act when in operation.` This anvil is secured to the jaw A by means of a thumb-screw, f, so that it can be turned and that either ot' its faces can be brought in a working position. That face on which the punches act is covered with a plate of sheet-brass or other soft metal, so as to save the cutting-edges ot' the punches from injury when they come in contact therewith, and some otthe other faces ot' the anvil are provided with sockets g to correspond in number and size to the heading-tools on the revolving head G.
In punching, the anvil is turned so that the face with the soft-metal plates stands opposite the punch, and after the requisite number of holes have been punched the anvil and the head C are turned and the appropriate heading-tool is brought in operation. The punching ot' holes and the insertion and heading of eyelets can thus be edected in a simple manner with little loss of time.
This tool is durable in its construction. The revolving head C is secured ou its center pin, so that the latter is not liable to work loose, bend, or break, and by making both the head and the anvil adiustable dilierent tools can be brought in operation with little loss of time.
PETER BAUER.
