PRINTING-PLATE-MOUNTINGr DEVICE.

Application letl December My invention relates to devices 'for serving as an accurate guide and, in addition,` as a temporary clamp in connection with the mounting of printing plates in chases, mounting boards or blocks.

While my invention has a wider application, l have designed it particularly tor use in making up a chase i'rom type plates 'for printing manifolding forms.

1n such printing it is the general practice to print on a wide web of paper, two or more copies of a form, side by side, so that when the paper is split along the dividing line between the form, there will result two like printed slips which may be used in manifolding.

It is necessary in this form ci printing to have the two or more type plates in a perfeet alignment and in case the alignment should become distorted 'for any reason to have a quick guide for setting the said plates correctly in the chase again. llt is also necessary that the spacing of' the variou's lengthwise Vlines inV each plate should correspond.

1t is the object ot my invention to provide a device which can be used in' connection with mounting boards or chases, and which not only serves as a guide to the press-man in arranging his plates in the chase, but also holds the plates in the corrected alignment until the clamping blocks, nail 'fasteners, or the like in the chase may be completely and permanently adjusted.

These objects and other advantages .to be noted 1 accomplish by that certain construction and arrangement of parts to be hereinafter more speciiically pointed out and claimed.

1n the drawings,

Figure 1 is a plan view showing the application ot the guide bar or straight. edge to a set of three maniiolding form plates in a chase.

Figure 2 is a front view showing the straight edge. device over a chase, and also (slightly separated) the clamping device.

Figure 3 is an elevation of a rack for mounting a series of standard straight edges, as used in manifolding form printing.

21, 1921. Serial NO. 523,807.

l provide any sort of support 1, for my device, which may be a liat wood or metal structure having side bars 2, 2. rllhese side bars are formed with 'lslots 3 for the clamping device, and lwith notched ribs 4 tor the straight edge. The support will also have a shoulder or rib 5 against which the chase may be set.

The straight edge comprises essentially a bar 6 having arranged along it a series of pointers 7 which are carefully positioned so as to correspond with some standard printing arrangement, such as in this instance, for a given vertical line of the sections of manitolding paper. This bar is adapted to seat in the notches of the ribs l and thus to be very accurately aligned across the bed.

@n one end of the straight edge bar is a small clamp 8, which straddles the rib, i. e. Slides upon it in any desired form of slider, and is held on the bar by a screw so that it can be clamped down to the ribs on the support in desired position. This clamp may, of course, be duplicated for use on both ends of the straight edge. l have not shown it in detail as any form of device can be used or the device omitted altogether.

The clamp for holding a. chase down on the holder is constructed as follows: Sta-ndards 9, 9, are provided having a brace rod 10 between them, and T-headed' bolts 11 enin the 'l--slots of the support and presenting` threaded ends for reception of clamping nuts 12.

Pivotally held in the standards is a rock shaft 13 having its ends 14k eccentric to the body thereof, so that it acts as a cam.

rllhe tie bar or brace rod 10 carries arms 15, 15, which extend to a point beneath the eccentrically mounted shaft. The arms 15 serve as the support for a mounting bar 16 and the arms are held rigidly on the rod 10, so as to hold the bar 16 against movement.

rEhe clamp bar 17 has a series of pins'or posts 18V thereon, which extend upwardly through the mounting bar, and have heads 19 lying in the path oi' the eccentric shaft. Between the Vheads and the mounting bar are springs 20, which bear against bar 16 and thrust up the pins normally to hold the clamp bar away from clamping' position. When, however, the shaft 13 is rocked by its handle 21 it will. contact with the heads ot the pins and thrust them down, whereupon the clamp bar will move to clamping position. v

As so constructed, the operation of the device is as follows; reference being had to a structure used with manitolding paper The press-manV arranges his printing` plates 22 in a chase 23, and thrusts the chase into the support until it abuts against the back shoulder thereoi". IIe then sets the straight edge piece which is designed Jfor his particular job and adjusts the plates in the chase until they are in exact alignment transversely, and until the various vertical lines ot the separate plates are in exact correspondence with the arrows Vor pointers on the straight edge.

He then thrusts down the handle of the eccentric shaft and clamps the plates and the chase as well into lined position, while he tightens up on the various blocks and hooks that move in the chase tor holding the printing plates..

There will be no shitting of the plates during` the tightening' operation, due to the clamp, and any chance shift will be at once noted on the straightedge.

I have shown in Figure 3 an end view of a support l, which has legs l, and at one end a rack 24.-. This rack is provided to support a variety of' straight edges, all of which are adapted lor use with the support, lout each of which has a diilerent pointer arrangement and has been pai-tiem larly designed for one of the standard kinds ot work to be done.

This multiplication ot straight edge pieces I tind of considerable economy ot time as against having adjustable pointers which would have to be carefully set and subject to chance dislodgment.

I do not wish to be limited to the details of construction above set forth, and do not wish my failure to mention various equivalent structures to be construed as a desire that my claims be limited in scope or application to the special form ot device selected tor purpose ot illustration.

I-Iaving thus described my invention, what I claim as new and desire to secure by lietters Patent, is:- n
