REGISTRATION PUNCH Filed June 27, 1961 BY-@Z @@5553 Attorneys United States Patent O 3,152,505 REGISTRATION PUNCH Harold H. Alidis, 3066 Stelling Drive, Palo Alto, Calif. Filed June 27, 1961, Ser. No. 120,028 4 Claims. (Cl. 83-468) This invention relates to a registration punch and more particularly to a punch for the punching and spacing of registration holes.

In the graphic arts, there is a need for a punch which can be utilized for precisely punching and spacing of registration holes.

In general, it is an object of the present invention to provide a punch which can be utilized for precisely punching and spacing registration holes.

Another object of the invention is to provide a punch in which precise control can be speedily achieved.

Another object of the invention is to provide a registration punch of the above character in which the exact spacing desired between the punched holes can be readily and precisely controlled.

Another object of the invention is to provide a registration punch of the above character which makes it possible to precisely position a plurality of holes.

Another object of the invention is to provide a registration punch of the above character which can be economically manufactured.

Additional objects and features of the invention will appear from the following description in which the preferred embodiment has been set forth in detail in conjunction with the accompanying drawings.

Referring to the drawings:

FIGURE l is a perspective view of a registration punch incorporating my invention.

FIGURE 2 is a side elevational view of the registration punch shown in FIGURE 1.

FIGURE 3 is a plan view of the registration punch shown in FIGURE 1.

FIGURE 4 is a cross-sectional view taken along the line 4-4 of FIGURE 3.

In general, my registration punch is utilized for punching holes in strips and sheets of stable base material. It consists of a base with a punch head mounted on the base. A bar is slidably mounted in the base in alignment with the punch head. Means is provided for precisely adjusting the position of the bar longitudinally of the groove or recess in which the bar rests. The bar is provided with a plurality of holes spaced precisely 1 inch longitudinally thereof. A pin is mounted in one of the holes and is adapted to precisely position a sheet of material to permit punching of a hole in a precise position by the punch head.

As shown in the drawings, my registration punch consists of a base board 11 formed of suitable material such as plywood covered with Formica. A recess 12 is formed on the top surface of one edge of the board. A pair of

bars

13 and 14 are affixed in the recess 12 by suitable means such as screws (not shown). As can be seen particularly from FIGURE 3, the

bars

13 and 14 are substantially rectangular in cross-section and extend the entire width of the board. The

bars

13 and 14 lie in parallel planes and are spaced apart to provide a groove 16 in which is slidably mounted another bar 17. It will be noted that the bar 14 has a thickness or depth which is greater than the thickness of the bar 13 so that it is provided with a raised portion 14a as can be seen particularly in FIGURES l and 2 which serves as a rear guide as hereinafter described. 'Ihe bar 17 is maintained in sliding engagement in the groove 1o at one end by means of micrometer adjusting means hereinafter described and at the other end by a screw 18 threaded into ice the bar 13 and sliding within a slot 19 provided in the bar 17.

The

bars

13 and 14 and the groove 16 can be formed from a single casting if desired. The groove 16 can then be machined into the casting.

A punch head 21 is mounted on the bar 14 adjacent one side edge of the board 11 and consists of a punch housing 22 which is secured to the bar 14 by suitable means such as a screw 23. A male die 24 is slidably mounted within the housing 23 for vertical movement within the housing. A shaft 26 is rotatably mounted in the housing and is adapted to be rotated by a handle 27. Cooperative means is carried by the shaft 26 and by the male die 24 so that as the shaft 26 is rotated, the male die is raised and lowered. This cooperative means takes the form of a groove or keyway 28 which is cut on the shaft 26. The keyway engages a rack tooth 29 provided on the male die 24. A spring 31 is mounted within the housing and is adapted to yieldably urge the male die upwardly to maintain the handle 27 in a substantially vertical position as shown. The male die 24 is provided with a shoulder 32 which is adapted to engage the housing to limit the upward travel of the male die. Upward travel is also limited by the rack tooth 29 binding in the groove 2S as shown in FIGURE 4.

It will be noted that the bar 17 has a length which is substantially less than the length of the

bars

13 and 14. This is for the purpose of providing a space for the punch head 21 and also providing space for adjustment of the bar 17 longitudinally of the groove 16 as hereinafter described. A spacer 36 is mounted on the righthand portion of the groove 16 adjacent the right-hand side of the punch head 21 as viewed in FIGURE 3. The punch head 21 also consists of a precisely positioned female die 33 portion which is provided with a hole 34 in alignment with the male die 24. The length of the bar 17 is chosen so that the bar 17 can be precisely adjusted at any point between the center position and a .predetermined distance such as one-half inch from each side of the center position for the bar 17.

Micrometer means is provided for precisely adjusting the bar 17 longitudinally within the groove 16 and of the

bars

13 and 14 and consists of a screw 41 which is threaded into the left-hand end of the bar 17 as viewed in FIGURE 3. The screw 41 is rotatably mounted in a plate 42 in such a manner that it cannot be shifted longitudinally in the plate 42 by a lock collar 45. The plate 42 is secured to the

bars

13 and 14 by suitable means such as screws 43. A knurled knob 44 is affixed to the end of the screw 41 and is provided to facilitate rotating of the same.

The bar 17 is provided with a plurality of holes 46 which are placed in the bar by suitable means such as drilling. The holes are precisely positioned in the bar and are spaced longitudinally of the bar with suitable spacing such as one inch between the holes. The bar 13 is provided with a pair of Vernier scales 47 and 48. These Vernier scales are in any suitable scale. For example, the scale for Vernier scale 47 can be in one-tenths of an inch, and the Vernier scale 48 in one-sixty-fourths of an inch. The knob 44 can serve as a micrometer type adjustment which is provided with a desired scale 49. For example, the large divisions on the scale 49 can represent .01 of an inch, and the small divisions can represent .001 of an inch. Where less accurate work is required, another scale 50 is provided on the bar 14.

A specially ground movable steel peg 51 is adapted to be positioned in any one of the holes 46 in the bar 17. When not in use, pin 51 can be stored in a hole 52 provided in the bar 14. Y

The

bars

13, 14 and 17 can be formed of any suitable 3 material such as aluminum. The scales can be placed thereon by suitable means such as engraving.

Operation and use of my registration punch may now be briefly described as follows. Let it be assumed that it is desired to precisely position holes in certain sheets or strips of material. This sheet of material 56 to be punched is held against the rear guide formed by the upstanding portion 14a of the bar 14 and positioned so that the first hole is punched in the right-hand end of the sheet of material. This first hole is then placed over the steel peg or pin 51 which is at the proper distance from the punch head 21. The exact spacing desired between the punched holes is controlled by the drilled bar 17, which bar is adjustable in increments of .001 inch up to one inch. By shifting the pin or peg 51 to the various holes, it is possible to punch and space holes from one inch to a distance substantially equal to the width of the base board 11 such as 23 inches and control their spacing to within .001 of an inch assuming the board to be approximately inches in width. The micrometer knob 44 controls the movement of the bar and is read as a micrometer. The inches and .1 of an inch are read on the scales provided on the

bars

13 and 14 and the .01 of an inch and the .001 of an inch are read on the micrometer wheel 44.

Assuming that the peg or pin 51 has been precisely positioned in the manner hereinbefore described, after the sheet of material 56 has been placed over the peg, the second hole is punched while the material is held against fthe back guide. This same procedure is repeated if more holes are desired. The back guide assures that all the holes will be in a straight line.

From the foregoing, it can be seen that I have provided a registration punch which makes it possible to punch holes with a precise spacing control. As is well known to those skilled in the graphic arts, such spacing control is indispensable when preparing combination burns, step and repeat flats, or the perfect punch out and Window combinations using a negative or positive with unexposed films. The registration punch is made in such a manner that it is suitable for heavy duty punch work and thus can be utilized for punching and spacing of holes in films before or after processing in various types of plastic sheeting, and in masking paper or light metal plates. My registration punch makes it possible to `obtain the maximum degree of accuracy in placing multiple images on any photosensitive surface.

The registration punch and board is manufactured of such materials that it will not be harmed by chemicals encountered in graphic arts work such as those encountered in dark rooms. It is also made in such a manner that it can be economically manufactured and readily maintained.
