DEVICE FOR LINING U1? PRESS FORMS.

Application filed April 1a, 1922. Serial No. 555,021.

To all whom it may concern.

Be it known that we, CLARENCE WV. NAEY, a citizen of the United States, and resident of Chicago, county of Cook, State of Illinois, and JAMES Wear, a citizen of the United States, and resident of Jamaica Plain, Boston, county of Suffolk, Commonwealth of Massachusetts, have invented an Improvement in Devices for Lining Up Press Forms, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts in each of the several views.

This invention relates to devices for the use of printers and more particularly for use in book printing or the like in which a number of pages are printed simultaneously upon a sheet which is afterwards folded and trimmed to produce the individual pages. In this class of work it is requisite that the type or plates for all the pages, which are thus assembled to be produced at once, be properly alined and spaced with respect to each other in order that each page will be correctly printed, and all the pages show the same margin when trimmed. The prineipal obj ectof the invent-ion is to provide a simple, convenient and easily operated device or appliance adapted to he applied to a type frame or chase and equipped with means for lining up and squaring both the head and back or side margins of a multiplicity of page units in the chase simultaneously. A. further object is to provide a device of the kind stated adapted to line up or square pages either of even or uneven sizes. A still further object is to provide a device of the kind stated adapted to line up and square quickly and accurately the page units in a chase whether the chase or iron frame in which the forms are locked be itself square and true or not, or whether the cross bars interiorly of the chase be true or not. The foregoing and other objects and advantages of the invention will more fully appear from the following detailed description taken in connection with the accompanying drawings, and the distinctive features of novelty will be pointed out in the appended claims.

Referring to the drawings:

Fig. 6 is a plan view illustrating the manner of use of the invention.

10 indicates a stout metallic bar of alength to extend across the chase or frame C which bear the page units P. This bar is shown as oblong in cross section, being preferably about one-half inch wide and one inch deep.

This bar 10 which constitutes a track on which the aliningelements of the invention are adj ustably fitted, has adjustably fitted to its end portions clamping shoes or blocks 11. These shoes 11 which are alike at each end of the bar, are each equipped on their tops and intermediate the length thereof with a boss 19. having a squared passage receiving and lifting the bar 10, these bosses being split at one side and equipped with clamping screws 13 passed through this split side and having handles 13, whereby the shoes may be clamped immovably in adjusted position upon the bar 10. Each shoe 11 extends a substantial distance each way from the cen tral boss 12 and has at its extremities bearing portions 14 adapted to engage the side of the chase. Intermediate the length of the shoe and directly under the bar 10 the shoe is also provided with a clamping screw-15 having an operating head 15 The bar 10 is graduated toward each end thereof symmetrically from a central point. For securing the bar or track 10 in correct and accurate position upon the chase, the clamp screw 13 of one of the shoes being released, that shoe is slid along the bar until the contact points 14 of the Shoe engage the side of the chase with the zero point of the bar central of the chase. The shoe is then clamped to the bar and the shoe at the other end of the bar adjusted up against the chase so that its contact points 14 engage therewith. Then the screws 15 are turned up to impinge against the chase. making a third contact point of the shoe with the o ase and permitting the bar to be securely claimed to the chase. The bar or track 10 has slidably fittted thereon, a housing sleeve 16 which has fixed to the bottom thereof a straight edge bar or strip 17 which is thus held to extend precisely at right angles to the bar or track 10. This straight edge 17 has its opposite sides beveled as indicated at 17 a and graduated usually in pica graduations. The passage through the sleeve 16 fits the bar 10 closely at its sides, but is provided with clearance as indicated at 16 for a small vertical movement of the sleeve with the straight edge 17 which it bears, with respect to the bar. The sleeve 16 is normally held at its upper limit of movement with respect to the bar 10 so as to hold the straight edge 17 in a raised position where it will not touch the press forms as it is adjusted thereover. For this purpose I show presser plates 18 adjacent the enes of the sleeve, equipped with studs 18 intermediate the length thereof and acted on by compression springs 19 surrounding the studs 18 and housed in hollow bosses20 at the top of the sleeve. For pressing the straight edge down ward with respect to the bar 10 so as to bring it directly upon the tops of the press forms I provide means shown as a cam head 21 in the form of a yoke pivot-ed at 22 to a block 23 and having a projecting hand piece 21. The block 23 has fixed thereto bars or rods 24 extending downward at the sides of the sleeve and having fixed at their lower ends a cross piece 25 extending transversely under the bar '10 and having a range of movement in a recess 26 out in the bottom and sides of the slee c. It will be understood that when the cam head 21 is in the po sition shown in Figures 2 and l, the straight edge 1'7 is elevated a small distance above the type forms, so that it may be slid along the bar 10, and when brought to position for alining the heads of a. row of page units it may be pressed into close proximity to the page units by movement of the cam head. To facilitate locating the straight edge 17 exactly central of the length of track 10, or for its adjustment along the track predetermined measured distances, the top of the sleeve 16 is provided with window openings 27 directly over the edges of the straight edge, and the sides of these window openings may be provided with ma-rlzs 27" precisely alined vertically with the sides of the straight edge. The straight edge 17 thus adjustablymounted upon the track 10 provides means whereby the page units may be lined up conveniently and with precision as to the headings thereof. F or alining the back or side margins of the page units by the same movements and adjustment we provide one or .rod.

more fingers or markers 28 adjustably mounted upon the top of the straight edge 17. As shown herein there may be four of tiesefingers on each end portion of the straight edge, i. e. at each side of the central sleeve 16. These fingers or marker plates 28 are adustably mounted upon rods 29 which are fixed the top of the straight edge 17 intermediate the width thereof. The inner ends of these rods are shown as fixed in sockets 30 which may be formed as depending lugs at the sides of the sleeve 16, while the outer ends of the rods are fixed in heads 31 fixed at the ends of the straight edge. Each of the finger or marker members 28 is equipped with a bearing boss 32, which affords relatively extending bearing on the rod 29 and is equipped with a set screw 33 for securing it in adjusted position upon the These bearing bosses are also made to fit the top of the straight edge as indicated at 82 so that the fingers 28 are held for sliding movement on the straight edge and in accurate alinement at right angles to the edges of the straight edge. Thus as the straight edge 17 is slid along the track 10 the fingers 28, having been first alined with the sides of one set of press forms, will be brought successively opposite the other lines of press torms in the chase so that the back margins or sides of the I press forms may all be brought in precise alinement. It will be noted that the device thus constituted is adapted to be applied to any size of form or chase within the length of the track 10, and that by reason of the spaced apart three point engagen'ient of the shoes 11 with the sides of the chase, it may be correctly applied even though the chase or frame may be out of square. Likewise the device may be applied either to the center or other parts of the form as may be desired. The sleeve r housing 16 having the straight edge 17 securely fixed thereto and being itself of substantial length with a bearing fit upon the track 10 insures that the straight edge will always be perfectly rectangular with respect to the track, while the described mounting of the fingers 28 likewise insures that these fingers or markers will always extend precisely at right angles to the straight edge. lVe are aware that the invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and we therefore desire the present embodiment to be considered in all respects as illustrative and not restrictive, reference being had to the ap pended claims rather than to the foregoing description to indicate the scope of the invention.
