20 Claims. l(Cl. 164-90) This invention relates to cutting, compression and punch press .devices and more particularly to a tape punching apparatus arranged .for multiple series punchings for various purposes. This application is a division of `a copending application of .lohn Winn and Edward S. Peterson, now abandoned, Serial No. 110,241, tiled August 13, 1949, and entitled, Compression and Punch Press Devices.

The most common type of compression and punching devices consists-of a head to which pressure is applied and a bed on which the material rests which is to be compressed or punched. Pressure is applied to the head 'by various lconventional means, while the bed is held or built up to withstand the pressure required to achieve the required objective.

A primary object of my invention is `to produce a compact 'compression or punching device that is capable of compounding applied pressure in Va simple uniform manner due to the head and Vbed of said device being linked together by various mechanical movements and moving in the same direction at different rates of speed during the compressing or punching process. Specically, this principle is applied to a device called a shopper and receptacle for punching and recording a series lof ,holes .setting up a code on a continuous tape .to .be used `as 'the master control in a system of improved means for ordering and assembling articles.

In accordance with my invention there is produced an improved and simplified method of mechanically increasing pressure for the compression, cutting and punching of various materials. It is inexpensive to produce and easy to operate. It is positive in its action. It is light weight and compact. It is manually operated with a minimum of applied force. 'It can readily punch .a multiplicity of holes in varying predetermined positions by simple adjustments.

Further objects of our invention will hereinafter appear from the following description illustrative of the invention and shown in the accompanying drawings in which:

Fig. l is a cross section of a receptacle showing a shopper in place and partly broken away to illustrate the force multiplying means;

Fig. 2 diagrammatically shows arack and pinion arrangement illustrating the force multiplying means;

Fig. 3 shows a multiple die for punching located in the end of the shopper;

Fig. 4 is a cross section on line 3-3 of Fig. 3;

Fig. 5 shows a punch plate;

Fig. 6 is a cross section on line 55 of Fig. 5; and

Fig. 7 is a perspective view of the shopper after operation and removed from receptacle.

The basic principle employs a moving head element carrying a punch and a die, and a moving punch operating bed or plate, which are linked together by various mechanical movements and which are both moving in the same direction at the same time and at different velocities. The dierence in speed brings the moving elements closer ICC 2 together and nally effects the punchingor-cutting of a sheet or bar which is positioned between the Ypunch and thedie. .A force Yapplied .to the head ismultiplied by said mechanical movements for the cutting or punching process.

As a .part of the system of improved means for ordering and assembling articles, there are a number of small similar ixed receptacles or frameworks each labeled as representing an article to be later dispensed. into one or more of v'these receptacles, there may be inserted a portable plunger device or shopper. Associated with the shopper is a die plate and punches, and with the receptacles a multiplicity of -punch plates each set up to cause various combinations of holes to be punched. The shopper holds a roll of `paper tape kfed over rollers and between Vthe 'punch and the die. A portion of the tape also rides under a typewriter ribbon fed from spool to spool and equipped with an automatic reversing kfeed for simultaneously printing on the tape from a slug of linotype Vmounted with the punch plate in the receptacle. Operation of the shopper by the insertions and withdrawals of the shopper in and out of the receptacles results in multiple punchings and printings.

This may be accomplished by mechanical means such 4as a lever vlink arrangement as shown, or by a primary rack, gear, pinion and secondary rack arrangement as shown or by hydraulic means or by blocks and cable.

Referring to the drawings, the device therein shown, as -illustrative of the basic principle lunderlying our invention 'and two embodiments thereof, 1 represents a plunger or a so-called shopper to be inserted into a receptacle or fixed framework 2. Associated with shopper 1 and receptacle 2 is ya selective :punching mechanism comprising a die plate 3, with holes A to M inclusive, a punch guide plate 4 separated from the die 31by a space 5' for paper, punches 6 (A to M) equipped with restoral springs '7 (A to M) `and punch stops 8 (A to M), punch extensions 9 (A to M), `a punch extension guide plate V10 (with holes A to IVI), and a punch plate 11 perforated in varying predetermined positions. The die 3 is equipped to receive the punches 6 fand each of said perforations corresponds Vin vloca-tion with a preselected punch 6 so that the unyperforated section of said punch plate forces the engaged punches 6 into said vdie '3. v Means are also provided for ymoving 4the die plate '3 andthe punch plate 11 in the same direction at the same time and at varying velocities.' The punch plate 11, as shown in Fig. 5, would punch holes .corresponding to locations B-C--FI-K.`

My amplified vcompression mechanism comprises a force transmitting lever arm 12 pivoted to the receptacle or framework 2 at a point 24 and contacting the lug 13 at point 14 on lever 12. The lug 13 lis rrnly mounted on the shopper 1. Pivoted to the lever 12 at point 15 is a connecting link 16, the lower end of which is pivoted at point 17 to the punch plate 11. A duplicate lever and link arrangement, not shown, are attached in an identical corresponding manner on the opposite side of shopper 1 to keep the punch plate 11 in balance.

Another specific application of my amplied compression mechanism wherein the punches 6 and the punch plate 11 move in the same direction, at the same time, but at different velocities comprises a primary rack 1S attached to a receptable 2a. Engaging the rack 1S is a gear 19 keyed to a shaft 20 which has suitable bearings in the sides of a plunger 1a. Keyed to the shaft 20 is a pinion 21 which engages a movable secondary rack 22, to the lower end of which is fastened a punch plate 11a. A duplicate set of racks and gears and pinion assembly, not shown, may be attached in an identical corresponding manner on the opposite side of plunger 1a and receptacle 2a to assist in keeping the punch plate 11a in balance. The interior of the plungers 1 and 1a contain a roll of paper tape which is fed through the space 5 between the die 3 and the punch guide plate 4 on to a take-up reel in the plunger by suitable tape advancing means also positioned within the plungers 1 and 1a. These plungers also carry a ribbon for printing on the tape from a slug of linotype mounted on the punch plates 11 or 11a which enters these plungers through an opening 23.

In Fig. 1, the distance from the point 24 to the point 15 is four fths of the distance from the point 24 to th'e point 14. Any predetermined ratio may be obtained by the location of point 1S with relation to points 24 and 1d. In operation, the pressure of an applied external force downward on the plunger v1 after insertion into the receptacle or framework 2 causes it to move downward until it contacts the plate 11 tending to push it downward. The plate 11 can move only four fths as far as the plunger 1 because the link 16 binds the plate 11 to the lever arm 12 cooperating with said frame by revolving about the point 24 as a fulcrum, and the downward movement of the arm 12 is restricted in movement by the lug 13 attached to the head 1. As the head 1 and plate or bed 11 move in the same direction downward at unequal velocities with respect to said framework, the difference in speed brings them closer together and thus eiects the punching with a force of approximately four times the external force applied to the plunger or driver 1 since said driver travels ve units of distance downward while the follower 11 travels four units downward, the resulting force being in accordance with the mechanical advantage of the mechanical motion employed.

Likewise in Fig. 2, as the plunger 1a is pushed downward, the gear 19 in the shopper engages the primary rack 18 in receptacle 2a. If the diameter of the pinion 21 is one fth the diameter of the gear 19, the same result is obtained with the primary rack 18 and secondary rack 22 as described above. If the secondary rack 22 is shifted to the left of pinion 21, the punching would occur on the up stroke instead of on the down stroke.

A hydraulic arrangement with pistons of varying areas associated with the plunger and receptacle would produce the same results.

In the system of ordering and assembling articles a` multiplicity of punch hole arrangements are required, one combination of holes for each article. A random combination of ve holes out of a possible thirteen is shown for illustration. A die 3 with thirteen holes is therefore shown and marked A to M, inclusive, the operating punches being B-C--F--I-K.

Regardless of the manner of operation of the shopper With respect t0 the receptacle, the punches 6 and the die 3 are always in the shopper or plunger 1, 1a which is pressed against the punch plates 11, 11a in the receptacle 2, 2a.

To set up various combinations of punched holes, the punch plates 11, 11a must be varied. A hole in punch plate 11, 11a allows the associated punch extension 9 to pass through the hole and renders the particular punch inoperative. A lack of a hole in the punch plates 11, 11a forces the punch extension 9 to move as the punch 11 and the die 3 approach each other thereby causing B, for example, to pass through the guide plate l into the die 3 to punch a hole in the tape located in the space 5.

It is to be understood that the above described embodiment of this invention is merely illustrative of the principles thereof and that numerous other modications may be devised by those skilled in the art which will fall within the spirit and scope of the principles of this invention.
