Specification of Letters Patent. latented liar.- 16,- 1920.
Application filed June 19, 1919. Serial No. 305,307.
To all w/wmit may concern:
Be it known that I, Gnonon Bnown, a citizen of the United States, residing at *wick, in the county of Kent and State if ilhode lsl ilti, have invented cer ain new and useful improvements in Grippers, of whic the following is a specification.
iy ventio slates to grippers for printing presses, has for its essential objects the inclusion in gripper of means for not only holding the paper in its place on the platen but also means for contemporane ously performing auxiliary operations. upon the paper being printed, such as cutting, punching. perforating, embossing and creasing. Further objects are compactness, inexpensiveness, strength, and facility of imunpulation.
To the above ends essentially my invention consists in such parts and in such combinations of parts as tall within the scope of the appended claims.
In the accompanying drawings which torm a part of this specification,
Figure 1 is an elevation of my gripper mounted on the gripper rocking bar, a portion of the latter being broken away,
Fig. 2, a side elevation of the same, showmg the rocking bar in section,
Fig. 3. a section on line 33 of Fig. 1,
Fig. i, a front elevation of the gripper engaged with a creasing member,
Fig. 5, a section or" the same on line i -5 of Fig. a.
Figs. 6 and 7, side elevations of portions of a creasing and perforating lade respec-- tively.
Fig. 8, an elevation of the gripper in which is mounted a punch.
Figs. 9 and 10, a side elevation and a central vertical section respectively ofa punch.
Fig. 11, a plan of an embossing die,
Fig. 12, a section on line- 1212 of Fig. 11,
Figs. 13 and 14, a plan and a transverse section respectively of a type holder and contents,
Fig. 15, a perspective view tab cutter, and
Fig. 16, a front elevation of a modified form of my invention.
Like reference characters indicate like parts throughout the views.
in the drawings 17 is the usual rocking bar of a printing press of the usual construction provided with a longitudinal slot 18 through which passes the bolt 19. The bolt also traverses a hole 20 in the base or enlarged end 21of the gripper. By means of a nut in conjunction with the head 23 of the bolt the parts are adjustably'clamped at any position longitudinally ofthe rocking bar. This attaching means is not exclusive.
The gripper proper comprises integral wi h its enlarged attaching portion 21 a bar or rod 25 ot' preferably rectangular cross section provided with threaded openings 2G, in this instance four in number, dis osed at equal intervals throughout the rod. In these openings are screws 28 slidable'through openings 29 similarly disposed in a clamping bar or rod 30. The heads 31 or the screws engage the bar 30.
In the form of gripper member shown in Fig. l included, clamped between the rods 25 and 80, a creasing member or plate 33 provided atintervals with holes 34: to admit the screw 28 therethrough. The blade 33 has an operating portion 36 which projects laterally beyond the plane of the rods .25 and 30.
When perforating of the paper is to be performed there is embodied in the gripper, in place of the blade 33, a like blade 88 provided with openings 39 for screws and having a series of cutting edges 41.
In Fig. 8 the gripper is provided with a device for cutting circular holes in the paper being printed. This device is a die comprising a rectangular body 48 provided with an annular cutting edge or elevation 44, extending from which through the body is an opening d5 to admit passage of the disks cut -from the paper. The block is preferably frictionally clamped between the rods and 30 with the operating portion projecting laterally beyond the plane of the rods 25 and 30.
In like. manner may be mounted in the gripper an embossing die comprising a rectangular body 16 provided in its upper or operating face 47 with a figured depression 4-8. This member is also clamped in such a manner that the operating portion l7 projectslaterally beyond the rods 25 and 30.
In like manner may be mounted in the gripper an oblong rectangular holder 50 carrying type 52 whose operating portions laterally project.
When it is desired to cut portions of the paper being printed, as for instance, to form tabs thereon, a plate 54 is provided having a lateral arm 55 with an upturned lip 56 upon its extremity. On the face of the plate is an arcuate blade 57 with a sharp cutting edge or operating face 58. The blade is fast in posts 59 on the face of the plate. The lip 56 may be clamped between the rods 2-5 and 30 of the gripper and the operating portion 58 projects beyond the plane of the gripper rods.
The gripper may comprise, as shown in Fig. 16, more than one clamping rod, as 62, in all respects like rod 30, except that it preferred it may be shorter. Thus several operations may be performed at once. The illustration shows a perforating blade 38 and a punching die 48.
It will be understood that a series of grippers may be attached to a single rocking bar 17.
It is apparent that the gripper may support in an analogous manner not only a type holder but electrotypes printing through an ink ribbon and such other deyiees as may be used for effecting paper visible or mechanically, Such action is better performed it the devices employed are free from contact with the ink rollers of the press. p 7 e The gripper operates in the usual manner. That is to say, it is located between the bed ot the printing press andthe platen, and as the latter advances to the bed the dieor i bar laterally thereof provided with spaced threaded openings, a clamping rod provided with spaced openings and clamping screws disposed parallel with the rocking bar extending through the openings in both rods.
2. In a printing press, the combination of a rocking bar, a gripper rod mounted on the bar, a elan'iping rod, clamping screws con-- necting the rods and members embraced by the rods provided with operating portions projecting laterally beyond the faces of the rods.
In testimony whereot I have afiixed my signature, e
GEORGE -H BROWN.
