Patented Nov. 10, 1931 UNITED STATES FRED W. DANAT, OF BUFFALO, NEW YORK LITHOGFAPI-IERS SQUARING-UP DEVICE Application filed October 28, 1929. Serial No. 402,876.
This invention relates to improvements in squaring-up devices designed particularly for useby lithographers in poster and sim1- lar lay-outs and as a transfer key.
It has for one of its objects to provide a device of this character which is so designed as to provide for accuracy of work and to afford a material saving in time to the lithographer.
Another object of the invention is the pro vision of a squaring-up device for lithographers which is simple and inexpensive in construction, which is easy to manipulate, and which insures a gripper space on the sheet for securing the same to the presses.
In the accompanying drawings Figure 1 is a top plan View of the squaringup device made in accordance with my in vention. Figures 2 and 3 are cross sections taken on the correspondingly numbered lines in Figure 1.
Similar characters of reference indicate corresponding parts throughout the several views.
Referring now to the drawings, 10 inclicates the drawing or layout board which may be of usualconstruct-ion for squaring-up and ruling drawings used in lithograph plants. Mounting on the top side of the board adjacent its marginal edges are a series of fiatwise disposed rules 11, 12, 13 and 14 which enclose the rectangular space for receiving the lay-out sheet 15. The rules 11, 12 which are disposed at right angles to each other and which extend along the top and right hand side of the board are preferably fixed thereto by screws 16 or other appropriate fastenings, while the rules 13 and 14 which are likewise disposed at right angles to each other and extend along the bottom and left hand edge of the board are flexibly mounted thereon to permit the ready insertion and removal of the adjoining marginal edges of the lay-out sheet to and from a position beneath said last-named rules.
For the purpose of permitting the rules 13 and 14 to be flexed toward and from the surface of the board, they are preferably madeof thin spring steel or like material and each is provided along its outer edge with a series of outwardly-facing spring members or lingers 17 which serve as attaching portions for the rule and which may be integrally formed therewith. These fingers are anchored to the board by screws 18 or like fastenings. Upon grasping the inner edges of these rules and lifting them, the lay-out sheet can be readily inserted beneath them preparatory to squaring the sheet on the board. While the flexible rules overlie the adjoining two marginal edges of the sheet, they do not in any way interfere with or resist the free shifting movement attending the proper positioning of the sheet relative to the several rules. In practise, after the sheet has beenproperly positioned, suitable clamps (not shown) are employed for holding the sheet in place. These clamps are usually attached to the board adjacent its corners and each carries a part which engages the top side of the sheet i adjacent a corresponding corner.
Mounted on the lower side of the board 10 along the outer edges of the rule 13 are a series of appropriately spaced guides or gageblocks 19 against which the lower edge of the lay-out sheet 15 is adapted to abut for properly'squaring it in place on the board, the upper edges of such blocks being parallel to the rule-edges and being in contiguous relation to the lower or outer. edge thereof, as seen in Figures 1 and 3. Similar gage-blocks 20 may also be disposed along the left side of the board in contiguous relation to the outer edge of the rule 14 for properly gaging the left hand edge of the sheet. For ruling the lay-out sheet horizontally a rule or straight edge 21 is provided which is disposed lengthwise of the board for alining registration with the scales on the rules 12 .r
and 14 and has adjustable guides 22 at its ends for engaging the opposite side edges of the board in the manner shown in Figure 1. The vertical rulings on the sheet may be made by a suitable angle, not shown. The
the press as Well as for gripping the sheet at its lower edge to hold it in place on the press. These provisions are taken care of in my device by the rules 13 and 14, the former constituting the gripper rule which results in the gripping space at the lower marginal edge of the sheet, such space being usually of an'inch wide and the rule 13 being of that same width. The gage side of the sheet is provided for by the side gage rule 14 and as the customary width of such margin is 1 the rule is of that dimension in width.
I claim as my invention 1. A squaring-up device for lithographic lay-outs, comprising a board on which the lay-out sheet is adapted to be placed, and a pair of rules mounted on said board at right angles to each other for overlying the adjoining marginal edges of the sheet, each of said rules having outwardly-extending resilient attaching elements for permitting flexure of the rules away from the board to relieve their pressure on the board.
2. A squaring-up device for lithographic lay-outs, comprising a board on which the lay-out sheet is adapted to be placed, a pair of rules flexibly mounted 011 said board in fiatwise relation thereto and at right angles to each other and biased to flex into engagement with the underlying marginal edges of the sheet, but being adapted to be flexed out of such engagement by external force applied thereto, and gage elements mounted on the board in substantially contiguous relation to the outer edge of one of said rules and against which an edge of the sheet is adapted to abut.
3. A squaring-up device of the character described, consisting of a pair of rules adapted to be flexibly mounted on a board at right angles to each other, said rules being constructed of a thin flexible material and provided along one edge with integrally formed resilient attaching fingers, whereby the rules are permitted to flex away from the board to relieve their pressure on the board.
