PAPER PERFORATOR.
Application filed December as, 1924. Serial No. 758,025.
To all whom it may concern:
Be it known that I, STEPHEN J. JAooB, a citizen of the United States, residing at Appleton, county of Outagamie, .and State of WVisco'nsin, have invented new and useful Improvements in Paper Perforators, 'of which the following is a Specification. 1
This invention relates to improvements in combined grippers and perforators for printing presses.
It is an object of thisinvention to provide for printing presses a paper gripper having a paper perforating blade resiliently mounted thereon and operable adjacent one side of the gripper so that the paper may be perforated in close proximity to the printing thereon.
Another object of this invention is to provide a paper gripper having mounted thereon a paper perforator which, by a reversal of the relative mounting between the gripper and perforating blade, may be alternatively used for right or lefthanol perforating. I i
A further object of this invention is to provide a simplified assembly of the gripper and perforating blade reversible in character and yet sturdy in structure.
Inthe drawings: a p
Fig. 1 is a fragmentary diagrammatic side elevation of a printing press showing the gripper and perforator mounted thereon.
Fig. 2 is a side elevation of one form of combined gripper and perforator.
Fig. 3 is a plan view of the same.
Fig. 4 is a fragmentary isometric View of the same with a section taken on the line 4-4 of Fig. 3.
Fig. 5 is a plan view of a preferred form of the device.
Fig. 6 is a fragmentary sectional view taken on the line 66 of'Fig. 5.
Like parts are identified by the same reference characters throughout the several views.
The printing press includes a stationary type carrying bed 1 and a platen 2 hinged at 3 for movement to and from the bed 1. The platen has also a horizontal movement toward the bed 1. This movement coupled with the pivotal movement brings the paper shown at 4 into contact with the type (not shown) secured in the chase 5 carried by the bed. The mechanism for operating the platen has not been shown for the reason that it is old and does not constitute a part of this invention. 7
Carried by the platen for relative pivotal movement thereto is a. gripper plate 6 which, 111 the forms shown .in Figs. 2 and 3 com prises a flat piece of metal having a pair of apertures 7, each situated adjacent an end of the plate and adapted to receive a bolt 8 on the printing press. 'There are two bolts 8 provided upon the press, one at the right and the other at theleft thereof, only one bolt being shown, however. The gripper plate is secured to the printing press by means of a'nut 9 upon bolt 8. 'The gripper plate has a recessed or cutawayportion 10 and at each end of the recess a slot 11 providing a pair of opposite tongues 12 adjacent each slot 11. Positioned upon the plate is a perforatingblade 13 reciprocable vertically thereof and having each end extending into a corresponding slot 11. This blade 13 is suspended at each end by springs 14, each secured to the plate 6 (Figs. 2 and 3) by screws 20. The springs 14 are each slotted at 15 to receive a portion of the blade, and the blade is slotted at each end at 16 to receive a portion of an associated spring. The springs and blade are thus interlocked to maintain the blade 13 in its position relative to the plate. Each of the slots 16 are flared outwardlyat 17 to provide working space for the spring 14 as the blade 13 reciprocates. slots 11 in maintaining the blade at substantially right angles to the gripper plate 6, a block 18 is provided, secured to the plate by a pair of screws 19. A shim 21 is positioned between each of the springs and the plate 6, the screws 20 forcing the overlapping portions of the springs about their respective shims for giving additional bindiirg effect between the screws and gripper ate. p The modified form of gripper and perforator shown in Figs. 5 and 6, is similar to that shown in Figs. 221ml 3, but differs in that one end only is provided with an aperture 7 adapted to receive a bolt 8 on the printing press. At each end of the tongue portion 22 is provided a slot similar to the slots 11 in the form of gripper shown in Figs. 2 and 3, the perforator 13 being recip- For. assisting the springs and their respective screws.
rocable in such slots in a manner similar to that disclosed in Figs. 2 and 3. Mounted upon the tongue intermediate its end is a block 18 for assisting. the slots 11, andsprings l i in guiding the perforating blade vertically relative to the plate and secured to the tongue by a pair of screws 19. r
The modified form of gripper plated is provided with recesses 23 at each end each side thereof. These recesses are adapted to receive one end of thev springs 1% which are secured to the gripper plate by screws 24, and. the sides ofitherecesses serve to prevent the springs from turning about y In the form of gripper plates shown, each of the screws 19 and 24 are inserted. into apertures which pass completely through thefgripper plates so that the screws may be engaged therewith at either side of such plate. Thus the arrangement shown 1n Figs. 5 andti may be 7 used for making right hand perforations and by a reversal of the parts be used for n'iaking left hand perforations. If it is desired to make lefthand perforations, all that is necessary is to remove the screws 19- and 251501 releasing the springs 1.4 and block 18, reversing the gripper plate sov that the recessed side of; the tongue 22 is upon the lower side of the gripper plate from. that shown in Fig. 5. The springs 14:." are then placed in their corresponding recesses 23 upon the opposite side ofthe gripper plate, the block 18 is placed upon the correspond.- ing side of the gripper plate, and the screws are then inserted in their respective aperture-s for securing the springs and block'- to the plate. In the formj of perforator and grippershown in- Figs. 2 and 3, the plate 6 is secured to the press bysecuring the left hand end thereof to the right of the press for right hand perforatiiw. When it is desired to make left hand perforations the right hand end of the plate as shown in Figs. 2 and 3-, is secured to the press in a manner similar to that previously described.
In operation, thev perforating device and gripper are brought into contact with the paper when, by reason of the horizontal and pivotal movement of the platen, the perforatingblade is brought into contact with a portion of, the bed 1 thus forcing the perforating blade against the supporting. springs and relatively toward the gripper plate. The pressure exerted by the perforating blade upon its supporting springs causesthe gripper plate. to come int-o'contact with the paper upon theplaten and to hold-it in stationary position during the printing and perforating process. hen the platen. recedes from the bed of the printing. press, the gripper plate follows the platen in its movement and maintains contact with the paper until the supportingv springs of the perforating blade force theblade away from the paper. The platen then is subsequently withdrawn from the gripper plate to permit replacement of the printed and perforated sheet.
