POCKET PAPER PUNCH Filed Aug. 6 5

Patented June 8, 1937 UNITED STATES PATENT OFFICE 1 Claim.

The invention relates to a punch and more es- 7 pecially to a hole punch.

The primary object of the invention is the provision of a punch of this character, wherein holes can be made in paper sheets or other sheet materials and such punch when not in use can be carried in the pocket of a garment similarly to a fountain pen and is readily serviceable for use by salesmen, clergymen, students, teachers and in lo fact anyone desiring to punch holes, such as pages adaptable for loose leaf binders.

Another object of the invention is the provision of a punch of this character, wherein the construction of the cutting tip or the punch tip is novel in form to assure quick and easy cutting of holes in sheet material, the body of the punch being formed with a chamber for receiving the loose material cut so that the possibility of the tip or cutting end becoming clogged or obstructed is eliminated.

A further object of the invention is the provision of a punch of this character, which is extremely simple in its construction, thoroughly reliable and efiicient in its purpose, strong, durable,

readily and easily carried in the pocket of a garment and inexpensive to manufacture.

With these and other objects in View, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawing, which discloses the preferred embodiment of the invention and pointed cut in the claim hereunto appended.

In the accompanying drawing:

Figure 1 is a side elevation of the punch constructed in accordance with the invention showing the cap for the cutting tip removed.

Figure 2 is a vertical longitudinal sectional View through the punch with the cover or cap piece fitted for concealing and protecting the cutting tip of said punch.

Figure 3 is a vertical longitudinal sectional view through the punch showing the same in cutting position with respect to work.

Figure 4 is a plan view of a sheet of material showing the holes punched therein through the use of the punch.

Similar reference characters indicate corresponding parts throughout the several views in the drawing.

Referring to the drawing in detail, the punch comprises a cylindrical body A forming a barrel providing interiorly thereof a collecting chamber 10 and at one end of this body is formed an outwardly tapered tubular bit H, the bore l2 therethrough being outwardly tapered and opens at its inner end into the chamber ID for direct communication therewith. The bit at its outer end is formed with a beveled circular cutting 60 edge l3 preferably corrugated in saw-tooth form as at M so that on penetration of the edge B into the work to be punched by rotation of the implement a positive cutting action will be had tor the severance of such work and the formation of a hole therein. It is, of course, understood that the shape of the cutting tip orend of the bit may be altered or changed as the occasion may require.

The end of the body A remote from the bit H is open and carries therein a removable plug l5 and this end is the striking end or that end to which pressure is to be applied when operating the punch for punching holes, the plug It: being in the nature of a stopper is telescoped and triotionally held in this open end of the body A. i

A cover or cap i6 is provided, the same being constructed with an axially disposed stepped socket ll such that the outer or larger portion of the socket will frictionally fit the barrel or body A of the punch when applied to either end thereof and the smaller portion of the socket will accommodate the bit I l of the punch when the cap is applied to the bit end of the punch. It will further be noted that the plug l5 has its outer shouldered end of such diameter that the same is flush with the body A and hence the cap, when applied to the plug end of the punch as shown in Fig. 3, fits over the plug as well as the body A. The cap 16 is applied over the bit end as shown in Fig. 2, when the device is to be carried'in ones pocket so as toprevent the bit from tearing the clothing.

Riveted or otherwise secured exteriorly to the body A near the striking end of the punch is a ball terminall-ed spring clip 20 which functions to fasten the punch within the pocket of a garment when carried on the person. It is, of course, understood when the punch is carried on the person the cover or cap l6 fits the bit end of the punch to conceal and protect the same as well as the garment when the punch is worn in the pocket thereof.

What is claimed is:

A punch having a main cylindrical body and a bit of lesser diameter atone end of the body, the bit and body having axially extending communicating bores therethrough; a combination striking closure-plug for the body detachably mountable on the end of the body remote from the bit; and a cap having an interior, axially stepped recess open at one end of the cap, the outermost portion of said recess of larger area being such as to fit over the cylindrical body of the punch when applied to either end thereof and the inner portion of the recess of lesser diameter being such as to accommodate the bit therein when said cap is applied to the body over the bit end of the punch.
