Specification of Letters Patent.

Patented Sept. 12, 1916.

Application filed August 22, 1913. Serial-No. 786,067.

To all whom t may concern:

Be it known that I, THOMAS E. HEETER, a citizen of the United States of America, residing in the city of St. Louis and State of Missouri, have invented certain new and useful Improvements in Punches, of which the following is a specification. j

This invention relates more especially to punch presses used for punching holes in loose leaves which are used in loose leaf prong binders, and has for its primary object to provide improved means whereby both single and double holes for all sizes of standard prong binders can be punched with this improved device by a slight adjusting of parts. l

Other and further objects will appear in the specilication, and be specifically pointed out in the appended claims, reference being had to the accompanying drawings exemplifying the invention, and in which,

Figure 1 is a front elevation of this improved punch. Fig. 2 is a rear elevation of Fig. 1. Fig. 3 is a plan view of this improved device. F ig. 4 is a transverse section taken on the line IV-IV, Fig. 1. Fig. 5 is a transverse section taken on the line V-V, Fig. 1.

Referring by numerals to the acompanying drawings: 1 designates the main frame, which is preferably bent into form from one piece of material, and comprises a base 2, an elevated horizontal portion 3, a bent return horizontal portion 4, a vertical portion 5, and a top horizontal portion 6. Secured to the rear of said main frame 1, and adjacent each end, are end supports 7. Located adjacent the center of said frame at the rear are a pair of'central supports 8. Secured to said main frame adjacent the center, and at the rear thereof, and between said central supports 8, is a brace plate 9. Said brace plate has a bearing 10 formed the-rein adj acent the top for the reception oit' an oscillating member' 11. Said member 11 has a shoulder 12 formed thereon which bears against the front side of the plate 9, and a shank portion 13 on which a handle 14 is fmounted. Said handle is held against movement on said shank portion by riveting a head 15 on said shank. Formed integral with said member 11 is a crank 16, said crank having an annular groove 17 formed thereon. Formed on the front edge of each end support 7, above the top 6 of the frame 1, are vertical cutaway portions 18. At the top of each cut-away portion on said end supports isformed a lug 19.

Formed'in the portions 3, 4, and 6 of the main frame 1 are a series of circular openings 20, all of said openings in said portions being in vertical alinement with each other. liteciprocably mounted in the vertical cutaway portions v18 are protruding ends 21 of a head 22, said head having an elongated opening 23 formed therein adjacent the center thereof.` Said opening is adapted to be engaged over the crank 16 of the oscillating member 11. Pivotally mounted at 24 to the front side of the head 22 is va retaining latch 25, said latch having an elongated opening 26 formed therein through which the pivot 24 is mounted. Formed adjacent one end of said latch is a recess 27. This latch 25 is for the purpose of holding the head 22 on the crank 1 6, the recess 22 engaging over the groove portion 17 of said crank after said crank has been inserted in the elongated opening 23 of vsaid head. Formed in said head 22 adjacent the lower edge are a series of elongated openings 28, each of said openings adapted to aline vertically with the circular openings 20 formed in the portions 3, 4 and 6 of the frame 1. Adapted to reciprocate in the series of `vertically alined openings 20 are a pair of punches 29, each of said punches having a transversely recessed portion 30 formed therein adjacent the top, thus forming a lip portion 31 on said punches. Said lip portion is for the purpose of securing said punchesto'the head 22 by inserting said lip portions in the elongated slots 28 of said head.

Formed in 'each of the supports 7 and 8 is an opening 32, said openings being in horizontal alinement with each other, and are `for the purpose of supporting the rear leg 33 of a gage member 34, said gage also having a front leg35 and an abutting portion 36. Pivotally mounted at 37 on'the inside of one of the end supports 71's an eccentric lever 38, which lever, when'pressed"down-` wardly, is adapted to bite'the rear leg 33 of etI pairs of holes. This improved device is operable in conjunction With either type of binder.

In theV operation of this improved device, if kit -is desired to punch single pairs of Vholes in sheets that are required for binders of the largest` single pair type, the punches 29 are insertedr into vthe series of circular openings A. In order to do this, the head 22 must be removed from its operating position, which removal is brought about by elevating the latch 25 and then pulling said headoff the crank 16. Then the lips 31 Yof said punches are inserted in the openings A', and the head 22 is again mounted onY the crank 16, and the latch 25 Y Ydropped into its normalposition. v The gage 34is'V set sothe abutting portion 36 thereof Will abut one edge of the sheets to be punched. v Y Y If it is desired to punch holes inv sheets for the medium size single pair binder, the punches'29 are removed and are inserted in the series of openings B, and the lips 31 of said punches are inserted in the openings B of said head 22. If it is desired to punch holes for the smallest type of single pair binder, the punches 29 are inserted in the series of openings C, and the lips 31 thereof are engaged in the openings C of said head 22. Y This completes the rearranging of parts to accomplish thev punching of holes Y in different sizedY sheets for the three different types of single pair binders novv in use.

When it is desired to punch holes in sheets for Vbinders that require double pairs of holes, one of the punches 29 is engaged in the series of alining openings D, and the lip 31v thereof is inserted in the opening D of the head 22. The other punch 29 Vis inserted in the series'of vertical alining openings E, and the lip 31-thereof is inserted in the opening E of the head 22. Y

The double pair binders are also of three sizes, and to accomplish the punching of holes for one of said sizes of binders a master sheet is first made. This is done by folding a sheet ofpaper on its longitudinal-center, and the centerV fold thereof is alined with the Ygage line F. Then the handle of the punch is manipulated. Then the sheet is Withdrawn and opened out. This punching struck out the master sheet. Novv the master sheet is placed upon a number of sheets which are to be punched, and the gage 34 is manipulated to have the abutting portion 36 thereof to one edge of the sheets in ac- Y cordance With the punches matching the holes on one side of the sheet Which has already been punched. The handleY of the punch is again manipulated and a pair of i .holes are Vpunched through the sheet in accordance With the holes of the master sheet. ThenV the sheets of paper are Withdrawn, and the gagel 34 is reset so as to match the punched holes of the master sheet With the punches so that pairs of holes can be punched through the remaining sides of the sheets.

In making a master sheet for the medium size binder, the folder line of said sheet is alined with the gage line G, and the same operation is followed as just described relative to the punching of the sheet for the smallest binder. And for the largest binder, the folded line of the master sheet is alined With the gage line II, and the operation is followed up as before.

It is to be noted vvhen sheets are to be punched they are inserted in the aperture 39 Which is formed between the horizontal portions 3 and 4, and the ends of the sheet Will abut against the rounded portion 40. Then the handle 14 is manipulated, and the punches are forced dovvnvvardlyl through the sheets. When the manipulation of said handle is reversed, the punches are drawn upwardly from the sheets.

What I claim is:

1. A paper punch comprising a frame, provided vvith a series of holes, a pair of removably mounted punches reciprocably mounted in said holes, a removable head reciproeably mounted above said holes, a series of slots formed in said head, said slots of said head being for the reception of the upper ends of said punches, and providing means for securing said punches to said head, said head during its reciprocation forming means for actuating Said punches in a pair of said holes.
