RALPH P. STEVENS, OF STl-lNFORD, CALIFURNIA.

CLIP-PUNCH.

inseam.

Application filed June 16, 1913.

To ail whom it may concern it known that 1, RALPH P. STEVENS, mg in Stanford, in the county of Santa lla. a and State of California, have inventd certain. new and useful Improvements in lip-Punches, whereof the following is a .ecification.

This invention relates to clip-punches for per irating paper, card-board, etc.

in carrying out the invention, 1 bend a strip of sheet or plate metal into the general form of a letter U, with the ends recurved so to form semi-cylindrical or other spaces. Upon one of these ends 1 mount a punch and in the other 1 make a registering perforation, so that when a piece of material is inserted and the ends squeezed together the material will be perforated. The ends of the semi-cylindrical space on the punch "eceiving side of the device are closed by suitable closures, at least one of which is remvable, and the punchings may be collected therein as a check on the number of times the device has been used,-a suitable stripper may be applied to the device described above, as will be hereinafter set forth in connection with the description of the drawings.

1n the accompanying one sheet of drawin l have illustrated my invention as embodied in what 1 consider its best form:

In the drawings: Figure 1 is a perspective view of a complete device. Fig. 2 shows the stripper tongue in perspective view ready to be applied. Fig. 3 is an elevation of the device partially sectionalized to show the punching means, and showing also a card inserted ready to be punched. Fig. 1- shows the U end of the device in perspective to illustrate the lugs between which the strip per holding projections engage, and F ig. 5 shows one of the closures for the semi-cylindrical punching box.

in these figures: 1 represents the upper limb and 2 the lower limb of a U shaped strip of spring metal. The free ends 3 and 1 oi. these limbs are recurved upon the outward side in more or less semi-cylindrical as shown in Figs. 1, 3 and 4. The recurvement t, upon limb 2, forms simply a convenient linger hold. The upper recurvement 3, on limb 1, not only serves as a linger or thumb hold, but also provides a box to receive the punchings, for which purpose its ends are closed, as clearly shown in Fig. 1. In Fig. 5 l have shown a con- Specification of Letters Patent.

venient closure 5 for this purpose, sheet metal is stamped out to the form of the space to be closed, but with projecting wings 6, which are then bent at right angles to the body of the piece so as to rictionally engage the walls of said space and retain the closure in position therein. One of these closures may be soldered in place if desired. A knob 7 serves for manipulating the lid.

8 is a punch mounted on limb 2, as shown in Figs. 1, 3 and a, and registering with orifice 9 on limb 1 so as to perforate a piece of inserted material and deliver the punchings into the box 3.

10 is a stripper tongue preforated at 11 for the passage of punch 8. This tongue, as shown particularly in Fig. 2, is formed of a strip of metal, having one end bent over upon itself, as at 12, for a double purpose to be presently described, and having two wings 13, extending from it at right angles. The tongue is applied to the device between the limbs 1 and 2 with the bent-over part, 12, against the limb 1, and is secured by bending the wings 13 up between lugs 14 provided on limb 1 for that purpose, and clamping their ends down upon limb 1, as shown in Fig. 1. The part 12 thus serves to separate limbs 1 and 10 so that a card may be inserted between them, and its end 15 forms a stop for the edge of the card to gage the distance of the hole punched from that edge. Thus the stripper moves with limb 1 and lifts the card oil the punch by the force of the spring of the U, there being no resilience necessary in the stripper tongue itself, which may be of any stiff material.

In Fig. 3 I have shown a card at 16 in position to be punched.

At 17, upon the recurvement 3, 1 provide a peep-hole whereby the operator can see into the box.

Having thus described my invention, and believing 1 have produced useful and novel improvements in the art to which it appertains, let it be understood that I do not wish to be limited to the exact construction and arrangement of the several parts composing the same, as many changes can be made without departing from the spirit thereof, but

What I claim and desire to secure by United States Letters Patent is:

1. A punch formed of a U shaped spring piece having punching means near its free ends, and having the perforated end re a piece of curved and provided with side pieces frictionally engaging the walls of said recurved end forming thereby a boX to receive the punchings.

2. A punch formed of a U shaped piece having perforating means near the free ends thereof, and having those ends recurved outwardly, one of said recurved ends being provided with side closures thereby forming a boX adapted to receive the punehings and the other recurved end forming a finger compressing means for operating said device.

8. A punch formed of a U shaped spring having the punching means near the free ends thereof and provided with a stripper between said ends, said stripper comprising a perforated tongue, a re-bent end and fastening wings, whereby it is spaced from the contiguous limb of the U and secured thereto.

4:. A. punch formed of a U shaped spring having the punching means near the free ends thereof, and provided with a stripper between the limbs of the U having a re-bent end to form a space therebetween.

In testimony that I claim the foregoing I have hereto set my hand in the presence of witnesses, this fourth day of June, 1913.

RALPH P. STEVENS.
