GAGE FOR MAKING PRINTING EQUIPMENT.

Application filed September 27, 1919.

T0 aZZ whom it may concern.

Be it known that I, Earn. E. NovoTxY, a citizen of the United States, residing at Logan, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Gages for Making Printing Equipment, of which the following is a specification.

This invention relates to gages, and has particular application to devices of tlns character adapted especially for use in the printing art for marking printing plates and matrices.

The marking of a matrix or a printing plate may be done for various reasons, such for instance as to obtain a predetermined paper margin for the printed matter to insure accurate registration of the plate on a printing press, and to attain a proper and selected superimposition of colors and the like on multicolor printing. The invention herein pertains to the structure of the gage itself, and while the latter is particularly well adapted for use in the printing art as hereinafter briefly referred to, I wish it to be understood that it is not limited in its application to this purpose of ing and marking printing plates or their matrices but may be employed in any con nection wherein it may be found advantageous or desirable.

The invention consists in construction, combination and arrangement of parts set forth in and falling within the scope of the appended claims.

In the accompanying drawings:

approximately centrally thereof and looking toward the marking flanges.

I will now proceed to describe my invention as used in conjunction with a body of type locked in a chase, as will be understood by reference to Fig. 2. From this type body we may assume that a matrix is to be molded so that it may be marked by the gage, during molding, with certain indications such as lines or scorings which are predetermined distances from the type forming portion of the molding face of such matrix as shown in Fig. 3. For the sake of illustration we may assume that it is desired to mold or cast from such a matrix a printing plate wherein a marginal edge of one inch will exist between the type and the edge of the plate. The type body shown at A is locked up in the usual chase indicated at B. At the time of locking the type body in the chase I also apply my gage thereto. In the form shown in Figs. 1 and 2 this gage embodies a U-shaped base or frame 1, which is adapted to span a bar of the chase, preferably adjacent one corner of the latter as shown in Fig. 1. This frame 1, may be of any suitable material, such as metal, and being wider than the chase bar may be rigidly fastened thereto in any convenient manner, such as by the insertion of furniture 2, between the inner legs 3, of the frame and the inner face of the chase bar, and by a set screw. 4, which is threaded in the outer leg 5, of the frame and which bears against the outer edge of the chase bar. The top face of this frame is grooved longitudinally as at 6, for the reception of a tongue 7, formed on the underface of the slide gage plate 8, so that while this plate may have a sliding or shifting movement upon or relative to the top of the frame, it is incapable of a lateral or sidewise play or movement. This sliding plate is formed with slots 9, through which project set screws 10, for the purpose of locking the sliding plate against movement on the frame in any selected position of adjustment, as will be readily understood. lVhile I have herein shown a pair of slots 9. and a pair of set screws 10, if desired, but one may be employed, or any equivalent arrangement may be resorted to for the purpose. The inner transverse edge of this sliding plate 8 is provided with an upturned beveled flange 11, the knife edge 12 of which is intended to mark or score the material of the matrix or plate C of Fig. 3 to form the mark or indication a for the paper margin as hereinafter described. Also formed on the top face of the plate 8', and extending parallel with but spaced apart from the flange 11, is a similar flange 13, the knife edge 14, of which will also mark or score the material of the plate or matrix C with a line Z) parallel to that made by the edge 12 of the flange 11, and the line or score so left by knife edge 14 may be used as a guide in trimming off the plate or matrix if desired.

In employing the gage the latter is clamped or fastened on the chase as shown in Figs. 1 and 2 and if it is desired to have a certain margin between the type matter of the matrix and the paper margin line a of such matrix, say one inch, a micrometer such as is shown at M is employed, the

anvil of the micrometer shown at 15 being placed against the selected type, border or rule of the body of type as shown in Fig. 2, and the slide 16 of the micrometer is then adjusted to the desired dimension, in the present instance, one inch, the slide being moved that distance from the anvil at the end of the micrometer scale or shaft. The sliding plate 8 is then shifted or adjusted until the paper margin flange 13 abuts the depending tongue of the micrometer slide so that the distance between this flange 13 of the plate 8 of the gage and the selected type, border or rule will be one inch. The screws 10 may now be tightened to clamp the sliding plate rigid with the base or frame thereof The chase with the type body locked therein and the adjusted gage clamped in position with its flange 11 one inch from the type may now be employed for the making .of the matrix partially shown in Fig. 3.

For instance, should the chase with the gage thereon as just described be placed in a press and a sheet of material, such as a plastic material placed on top of the type and chase, and subjected to pressure, in addition to the type being reproduced in the face of the sheet,'the score mark a will be reproduced by the knife edge 12 of the flange 11,-which mark. will be one inch from the type impression T, and the second score mark I) made by the knife'edge 14: of the flange 13 will be reproduced in the sheet of material, parallel with but spaced from the score or mark a; Vhen the sheet has been trimmed along the outer score or score mark 5, the material cl lying between such trimmed edge and the mark a may constitute a clamping margin which may lie be neath a clamping member when the matrix is placed in the casting box or other apparatusfor casting plates from the matrix.

Of course, if desired I may provide the division of the scale.

sliding gage plate 8 with but one knife edged flange for scoring or marking purposes, as under many circumstances but a single score line or indication would be suflicient.

In Figs. 4: to 6 inclusive, I have shown a slightly modified form of the invention, in this instance it not being neecssary to employ the separate micrometer M as is shown and described in Fig. 2. Referring to said Figs. 4 to 6 inclusive, the U-shaped base or frame 17 of the gage has one side edge thereof divided into a scale 18 running from 0 to 12, the divisions of the scale representing picas,.there of course being 6 picas to the inch which is a standard printers measure. Slidably mounted on the top of the frame 17 is a plate 19 having an elongated slot 20, and set screw 21, by means of which the plate may be held in any selected position of adjustment relative to the top. This plate 19 is also provided with a tongue 22, seating in'the groove 23, in the top of the frame 17. A second elongated slot 24:, is formed in the plate and through this slot projects a shank 25 of a T shaped block 26, the head of the latter seating in a groove 27, formed in the top wall of the frame 17. The head of the block 26 is threaded onto the screw shank of the micrometer screw 29, the head 30 of the latter being marked circumferentially with a scale 31, the divisions of which indicate points of which there are twelve to'the pica, so that one complete revolution of the micrometer screw is equivalent to one pica. A small spring pointer 32 is fastened at one end to the frame 17, and its opposite end or point seats in grooves 31 constituting the indicating lines of the scale 31 and thus this pointer will positively aline with the selected The micrometer screw 29 is held against longitudinal movement by annular flanges 33, so that with the rotation of the micrometer screw the block 26 thread- 110 ed thereon will be caused to travel in its slot. The side edge of the sliding plate 19, adjacent the scale 18 of the frame is provided with a row of bores or holes 34, the centers of which aline with the division lines 115 or marks of this pica scale 18. An alining pin is intended to selectively seat in the holes 34, the shank end of this alining pin also seating in the socket 36 formed in the side of the block-shank 25. j

The manner of employing this ,form of gage will be readily understood. Referring to Figs. 1 and 5, if it is desired to shift the plate 19 on the frame 17 a distance equal to a number of picasthe aliningpin 35' is 125 withdrawn and the plate is shifted with'the hand until the hole or aperture 3 1 indicating that particular pic.a,considered from'the zero mark, is brought into alinement with the zero mark on the scale 18 of the frame 17. 130

The pin may then be thrust back or socketed in the shank 25 of the block, being of course inserted in the hole which at that time has been brought into alinement with the socket of the block. If, however, it is desired to shift the sliding plate 19, relative to its frame 17, a smaller distance than one complete pica, as where it may be desired to obtain a dimension of picas and points, or parts of a pica, then it is only necessary to turn the disk 30, constituting the head of the micrometer screw 29 until the scale 31 in conjunction with the pointer 32 indicates that the sliding plate has received the desired degree of movement. Of course this rotation of the micrometer screw will cause the block to feed along the screw the selected distance, carrying with it the plate 19 which is connected with the block at this time by the alining pin 35. It will thus be seen that relatively large or rough dimensions or degrees of movement of the plate relative to the frame may be obtained by simply pulling out the alining pin 35 and shifting the plate bodily with the hand, again inserting the pin after the gate has been moved to the desired extent.

ut where fine dimensions or minute degrees of movement are required, for instance less than a full pica, then the micrometer screw may be resorted to and this screw will not only shift the plate but will indicate clearly, by means of the pointer and the scale on the disk of the micrometer screw, when the plate has been shiftedto theproper degree. Of course this sliding plate 19 is provided with the marking flanges, in the present instance shown at 12 and 14' these flanges performing the same functions for those described for the structure shown in Figs. 1 and 2.

I have herein merely briefly outlined a particular purpose for which my invention may be used, but obviously it may be employed as a marking gage under any condition where its employment will be found advantageous.
