PUNCH.

SPECIFICATION forming part of Letters Patent No. 759,709, dated May 10, 1904. Application filed February 16, 1904. Serial No. 193,874. (No model.)

To all whom it may concern:

Be it known that I, HUB ERT C. HART, a citizen of the United States, residing at Unionville, in the county of Hartford and State of Connecticut, have invented new and useful Improvements in Punches, of which the following is a specification.

This invention relates to im iirovements in hand-punches of the type stamped from sheet metal and bent into the desired configuration to produce a cheap and commercial article.

The object of the invention is to provide a pair of punch members stamped of sheet metal and adapted to be pivoted together, one of said members carrying a punch and ejector, the other member carrying adie and a piercing-receptacle, the latter also being stamped from sheet metal.

With these general objects in viewl will proceed to describe in detail the construction and operation of the device, the salient points being more particularly brought out in the claims.

In the drawings, Figure 1 is a side elevation of my improved punch. Fig. 2 is a vertical section of the punch, showing the members open. Fig. 3 is a transverse section taken on the line a: a: of. Fig. 1. Fig. 4 is a horizontal section taken on the line y ;1 Fig. 2, and looking in the direction of the arrow a. Fig. 5 is a similar section taken on the line y y, Fig. 2, looking in the direction of the arrow I). Fig. 6 is a detail inverted perspective view of the piercing-receptacle.

The numeral 1 represents a member of a punch, and the numeral 2 a companion member, the two members being pivotally connected together with a pivot-fastening 3. The member 1 is stamped from sheet metal and comprises a handle 1 and a punch-carrying jaw 5. In order to brace and strengthen this member, the metal is bent at an angle from the flat portion of the handle 4: and the jaw 5, as shown at 6, and an opening 7 is formed in said flat portion, and adjacent thereto the sides 6 are slightly bent outward, as at 9, to form a side bearing for the companion memher 2. A punch 10 is riveted in the flat face of the jaw 5, and adjacent and behind the same is the usual spring-ejector 11, the free end of which is dropped slightly below the outer end of the punch and is provided with an elongated opening 12. The rivet 1 1*, which secures the ejector, impinges the face of the die-carrying jaw and limits the movement of the punch.

The member 2 is stampedfrom sheet metal and is of approximately the same shape as member 1. It comprises a handle 13, die-carrying jaw 14, and the bent sides 15. Cbviously to facilitate the manufacture of the members 1 and 2, as well as to lighten it, the member 2 will, like member 1, have an opening 17. This enables me to manufacture both blanks from which the members are formed from the same die.

Between the sides 15 of the member 2 and adjacent the die-jaw is pivoted a piercing-receptacle .19, stamped from sheet metal and comprising a bottom 20, one end of which is bent up to form a rear wall 21, while its longitudinal edges are bent to form side walls 22. The sides extend slightly beyond the walls 21 and are perforated to receive a pin 33, the pin also passing through openings in the sides 15. A spring 2 1 is coiled around the pin and serves to normally throw the receptacle up within the hollow portion of the member 2. in order to provide a convenient lingerpiece to empty the piercings from the receptacle, the front 20 of the bottom is extended slightly beyond the front of the side walls 22 and [its under the front portion of the flange 15, which forms the sides. Thus a projection is conveniently located to enable a persons linger-nail to be slipped between the front 20 and the member 2,when the tension of the spring can be readily overcome and the plercings w ll slide out.

The member 2 is passed through the opening 7 of mel'nber 1 and the two are pivoted together by the pin 3, and around said pin is coiled a spring 26, one terminal of which bears in the hollow portion of the handle 13, while the other terminal is formed into a loop and bears in the hollow portion of the handle 1. The tension of the spring is such that it normally throws the punch and die-jaws apart, as will be understood by reference to the drawings.

A punch constructed in accordance with my invention is formed from sheet metal and shaped in suchmanner as to-strengthen the parts toresist the strain in the direction in which it is applied. Furthermore, the construction enables me to produce a cheap, neat, and light punch and one not liable to become out of order.

What I claim as new is- 1. A punch made from sheet metal which consists of two members, one of which is bent to form a handle and a punch-carrier, and the other bent to form a handle and a die-carrier, the sides of the punch-carrying member being increased in width opposite an opening formed intermediate said punch-carrier and handle between which the member having the die-carrier passes, a punch, a die, a pivot-bolt fastening the two members together, a. spring to normally hold the punch anddie apart, a piercing-receptacle made from sheet metal and bent to form a flat bottom open at its front end to provide a lip and closed at its rear end, and sides extending beyond the rear end where said sides are perforated, a pivot for fastening the receptacle within the bent sides of the die-carrier, and a spring for normally closing the said receptacle, substantially as described.

2. A punch comprising two members formed from sheetmetal and bent to form surrounding sides, perforations formed in the sides of onemember, a punch, a die, a piercing-receptacle made of sheet metal and bent to form a bottom which has its rear end bent to form a rear wall while its front is flat to form a lip, sides bent up from the bottom which terminate back of the lip of the bottom and which extend beyond the rear wall to form ears which are perforated, a pin passing through said perforations and the perforations in the member, a spring around said pin to normally hold the receptacle into contact with the member to which it is pivoted, the sides and rear of the receptacle being fitted within the sides of its coacting member, the lip normally fitting against the bottom sides of said coacting member under the influence of its spring, substantially as described.

3. A punch comprising two members, one of which is provided with a punch while the other is provided with a die to receive the punch and an open portion formed under the die, a piercing-receptacle made of sheet metal and bent to form a bottom which has its rear end bent to form a rear wall and its front being flat to form a lip, sides bent up from the bottom which terminate back of the lip of the bottom and which extend beyond the rear wall to form ears which are perforated, a pin passing through said perforations and the perforations in the member, a spring to normally hold the receptacle in contact with the member to which it is pivoted, the sides and rear of the receptacle being fitted within the sides of its coacting member, the lip normally itting against the bottom side of said coacting member under the influence of the spring, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
