.1 This. invention, relates to a form locking-up device, and. its. principaljobjeot is to provide improved lock-up mechanism for locking up printing forms and at the sametin e to dispense with printers quoins, printers furniture or otherlockup material, in thelocking up of forms within or without a printers chase, press, galley or the like. 7 Another object is'to provide improved lockingup mechanism that can be adjusted to fit any printer's chase, press, galley orthe likewithout in any way altering the manufactured form of any of these devices. i

Another objectis'to provide improved lockingup mechanism that enables forms "to be locked up without any strain or stress upon the chase or press; the strain going against the form.

Another objectis to lock the lock-up means in the adjusted'position thereof, wherebyvibration or jars cannot loosen the locking bars from their hold against the form or typefa nd-caii be locked up at any predetermined position in the chase or press. i

With these and. other objects and advantages in view, this'invention consists inthe several novel features hereinafter fully set forth, andlmore particularly defined in the-appended claims. T

In the stub shafts. 32,

35 are formed

sockets

40, 4|. into which a wrench li xor the i l fle s Ri h in ert for the purpose of rotating the pinions. The socket 45 is of greater diameter than the socket 4|, whereby one tool may engage in the socket 443 and rotate the pinion 24 without rotating the pinion, and a tool of lesser diameter may enter the socket 4| to rotate the pinion 25 without rotating the pinion 24. Rotation of the pinion 24 in one direction moves the slide 22 along the lock-bar I2, and rotation of the pinion 25 moves the slide along the lock-bar I3.

Each lock-bar is preferably provided with a longitudinal extending groove 43, in which travels a lug 45 which projects from the slide. The groove end lug connections provide means for guiding the slide to move along both look bars.

The slide is further provided with two sets of locking means designated generally by the reference character 46, to lock the slide to each of the intersecting lock-bars associated therewith, whereby to prevent vibration from loosening the lock-bars from the form. As shown, each locking means comprises a worm 46 rotatably mounted between

cars

42, 41, which extend up from the base of the slide. A headed pin or screw 49 extends through the worm and through slots 50 in the ears 4'2, 41. The worm is moved toward and away from the teeth of the racks by a yokeshaped finger piece i, having arms 52 pivotally mounted on the pin 49, and having curved slots 53 non-concentric with respect to the pin 54. The pin 54 is secured in the

ears

42, 41 of the slide and extends through the slots 53 in the arms 52, and causes movement of the arms and therewith the pin 49 and worm 46 toward and away from the lock-bar rack. When the finger piece is swung downwards to the position seen in Fig. 5, it moves the worm 46 toward and into mesh with the teeth of the associated rack. The teeth of the worm are helically disposed thereon to enable them to be meshed with the teeth of the rack in any adjusted position of the slide, and

the teeth are notched at several places around their circumference to facilitate turning the worm into mesh with the teeth of the rack. If desired, the threaded pin 49 may be threaded in one of the arms of the finger piece so that by turning up the threaded pin tightly, the finger piece will be clamped against movement.

In operation the lock-bars are moved up against the form, and the pinions rotated to bring the lock-bars tightly against the form, and the finger pieces are then depressed, thereby meshing the worms'with the rack teeth.

In the modified form of the invention, illustrated in Figs. 8 and 9, the form ll is surrounded by type high foundry bars 60. In this form of the invention the lock-bars I2 and I3 are of the same thickness, so that one may lie above and across the other, their ends being formed with heads 6|, in which are secured threaded stems l8, upon which are threaded discs I9, as in the preferred form.

The lock-up means 2| is constructed substantially in the same manner as the corresponding lock-up means of the preferred form of the invention, and the form locking-up device is secured in a chase In, as in the preferred form. This modified form of the invention is shown as applied to a foundry form.

In the forms of the invention hereinbefore described, double lock-up devices are providedthat is to say, the double lock-up means operates on two lock-up bars.

In the form of the invention illustrated in Figs.

10 and 11, a single lock-up device 2l is illustrated in connection with a short lock-up bar I2 which bears against the lock-up bar I3 In this form of lock-up device only one pinion 24 is employed, which meshes with the rack teeth of the lock-bar I2 This form of the invention is illustrated in connection with a foundry form, in which the .form I It is locked in place in the chase. 60 designates type high foundry bars that surround the form.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention; hence I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described, or uses mentioned.
