CHARLES R. GETHER, OF MILWAUKEE, WISCONSIN.

PATENT orrion PUNOI-IING-MACHINE.

Specification of Letters Patent.

Patented July 14, 1908.

Application filed September 30, 1907. Serial No. 395,073.

To all whom it may concern:

Be it known that 1, CHARLES R. GETHER, a citizen of the United States, residin at Milwaukee, county of Milwaukee and tate of Wisconsin, have invented new and useful Improvements in Punching-Machines, of which the following is a s eciiication.

My invention re ates to improvements in that class of punching machines which are used for perforating the marginal edges of sheets of paper preparatory to being connected together by the modern so-called loose leaf binder, and it pertains more especially among other things, first, to the mechanism by which a plurality of unches are adjustably connected. with an simultaneously operated by a single revoluble punch operating shaft, and second to the means employed for communicating a vertical'reciprocating motion from the. operating agency to the punch operating shaft.

The construction of my invention is explained by reference to the accompanying drawings, in which,

Figure 1 is a front view of a machine. Fig. 2 is a vertical sectional view drawn on vertically dotted line of Fig. 1. Fig. 3 is a detail showing a modified form of device for operating the machine by foot power.

.Like parts are identified by the same reference characters throughout the several views.

2 represents the punch actuating shaft which is revolubly supported at its respective ends in journal bearings 3 formed integrally with the supporting frame 4. The shaft 2 is rovided upon one side with a lon gitudinal fiange 5 which is'adapted to engage in transverse grooves 6 formed near the upper ends of the several punch shanks 7.

8 represents the punch guides which are provided with a vertical a erture for the reception of the punch shan s 7. Theseveral punch guides 8 are connected with a die late 9 which y screws or rivets in the ordinar manner and each punch guide is also provi ed with a gage 10 which is slidably supported in an aperture provided therein and secured at any desirable point of adjustment by the hand screw 11. j

The unch guides 8, die plates 9, and gages 10 are a lof the ordinary construction. When such parts are connected together as shown in Fig. 2, they are rigidly secured at any desirab e point of adjustment to the supporting I I bar 12, by the hand actuated is permanently secured thereto bolts'13. The bar 12 is provided with a lon itudinal slot 14 for the reception of the hand actuated bolts 13; The die plates 9 of each set are adapted to rest upon the upper surface of the bed plate 15, and said bed plate is supported from the frame 15. 16 is a longitudinal slot formed in the bed plate. Thus it is obvious that by releasing the hand bolt 13, the punch guide together with the punches, die plates and other connecting arts are adapted to be adjusted longitudinalfy of the slot 16, whereby a greater or less number of punches and dies may be used at a time and such parts may be adjusted nearer to or farther from each other as the various kinds of work to be erformed may require, while owing to the fact that the shanks 7 are connected with the operating shaft 2 by a longitudinal flange 5, operating in the groove 6, the punch dies and parts rigidly connected therewith may be readily and quickly adjusted longitudinally of the operating shaft, it being necessary when desirous to change the adjustment of such parts to simply turn back the hand bolt 13 until the desired adjustment is made when they are again secured in place by turning down said hand screw 13 against the retain ing bar 12.

When desirous to operate the punches by foot power, the shaft 2 is connected with an operating pedal 16 by pivotal bolt 17, link 18, pivotal bolt 19 and lever 20, which lever 20 is rigidly affixed to one side of said shaft 2.

21 represents a spring by which the pedal 16. is connected with a stationary part of the machine not shown.

In operating the device, the punch is forced downwardly by the downward pressure of the pedal 16, while the spring 21 is we anded, when by releasing the pressure on the pedal, the pedal is moved in the opposite direction by the recoil of said s ring, whereby the punch is raised and wit drawn from the paper.

By the preferred form of operating mechanism shown in Fig. 2, motion is communipunch actuatin shaft 2 through the pulley supportin sha t 23 eccentric 24 (which .is rigi ly a link 26, pivotal bolt 27, lever 28, segmental gear 29 and segmental car 30. The segmental gear 29 is forme integrally with or connected to the lever 28. The segmental gear 30 is formed integrally with or concated from the power driven pulley 22 to the 7 Xed to said shaft 23,) collar 25,

nected to the shaft 2. It will be obvious that with each revolution of the pulley 22, a vertically reciprocating movement will be communicated therefrom to the several punches through the several parts named.

or convenience of description the punch, die plate, punch shank and guide, which are all rigidly connected and adapted to be moved together are hereinafter referred to as punch and die sets.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is,

1. In a machine of the class described, the combination of a revoluble punch actuating shaft, a longitudinal flange affixed to and projecting radially from the periphery of said shaft, a plurality of punch and die sets, the punch shanks of which are respectively provided with transverse grooves for the reception of said longitudinal flange u on which they are adapted to be longitucinally adjusted, means for adjustably connecting the several punch and die sets together above a suitable die su porting bed plate, a die supporting bed p ate, an operating lever and means for communicating motion from said lever to said revoluble punch actuating shaft.

2. In a machine of the class described, the combination of a revoluble punch actuating shaft, a longitudinal flange connected with the eriphery of said shaft, a plurality of punc h and die sets, the punch shanks of which are respectively provided with transverse grooves ada ted to be adjustably connected with said fbngitudinal flange, means for adjustably connecting the several unch and die sets together above a suitab e die supporting bed plate, a die supporting bed plate, a frame for supporting said bed plate,

a-revoluble power driven shaft supported from said frame, a driving pulley supported on said shaft, an operating lever connected with said punch actuating shaft, means for communicating motion from said power driven shaft to said lever and means for communicating motion from said lever to said. revoluble punch actuating shaft.

3. In a punch machine of the described class, the combination of a revoluble punch actuating shaft a longitudinal llangeprojecting from the periphery of said shaft, of a plurality of punch and die sets, the punch shanks of which are respectively provided with transverse grooves for the reception of the longitudinal flange of the punch actuating shaft, means for adjustably connecting the several punch and die sets together above a suitable die supporting bed plate in adjustable connection with said actuating shaft, a die supporting bed plate, a frame for supporting said bed plate, a revoluble power driven shaft supported from said frame, a driving pulley supported on. said shaft, an. eecentric rigidly connected to said shaft, a collar slidably connected to said eccentric, an operating lever connected with said. punch actuating shaft, means for communicating motion from said eccentric and inclosing collar to said lever, and means for coinmunicatiug motion from said lever to said punch actuating shaft.

In testimony whereof I affix my signature in the presence of two witnesses.

CHARLES R. GEIIIER.
