APPARATUS FOR PREPARI ENG TYPE-3AM OR SLUGS FOR USE IN PRINTING-FORMS.

Original application filed July 2, 1915,

To all whom it may concern.

. Be it known that I, DAVID S. KENNEDY, a

for preparing type bars or slugs, such as are cast in the commercial linotype machine,

for use in printing forms.

Certain classes of work, such as advertising, illustrative matter and the like, require the use of cuts or printing plates in the form,

and to meet this requirement, the plain portions of the slugs lying beyond their type characters are usuallyycut off to provide an open space-in the form for the-reception of a supporting block uponwhich the cut is mounted. This-practice is objectionable, as

'it not only involves a number of different operations which entail much labor and'loss of time, but in addition difliculty is experienced in looking up the form in the proper and exact manner required. Furthermore,

since they must be specially prepared to correspond to the particular style of plates to be inserted, and they can rarely be used after one service.

My invention is intended to overcome the above objections and aims to prepare the slugs so that they themselves may receive the printing plate and give it direct support. To this end, I propose to cut down or reduce the plain portions of the slugs so that the plate or cut may be placed thereon and supported at type height.

In the use ofmy improved apparatus, I preferably follow the method of procedure outllned in my earlier application before re ferred to. cast slugs side by side upon a suitable sup- That is to say I assemble the port, then shift them endwise relatively to each other to bring the ends of their lines of type characters into transverse alinement, and thereafter cut down or reduce progressively or suces'sively the plain edge portions of the slugs beyond the type characters. The slugs are subsequently locked up in the printing form,-and in the condi tion their reduced portions will present a flat surface upon which the cut may be laid and supported at type height. The feature of preliminarily bringing the ends of the type lines into transverse alinement is particularly advantageous in facilitating the trimming of the slugs for the reception of cuts of irregular form or contour, it being understood that the slugs which are produced for use in connection with such cuts have their type lines of varying predetermined lengths to correspond. A whole series of such slugs may thus be trimmed at one operation, since the relative shifting of the slugs necessary to bring their type lines into transverse alinement will also locate their plain portions, which likewise vary in extent, 'in proper position for the trimming action.

This feature might also be advantageously slug is provided with a line of type characters Z. extending partly along its edge,

and with a recess Z extending along the re-.

dotted lines. When a number of such slugs are assembled side by side in the form, as in the manner indicated in Figs. 5 and 6, they provide a plain and fiat supporting surface corresponding in form to that of the print ing plate to be mounted thereon, it being remembered that when the plate is of irregular form the recessesztwill vary in length on the respective slugs so as to adapt the outline of the supporting surface to cor respond.

While my improved apparatus is particularly ada ted to carry out the method above noted an will hereafter be described with reference to such method, I wish it to be distinctly understood that my invention contemplates any method that may be followed in the use and manipulation of ratus now to be described.

As shown in Fig. 1, the slugs Z, just as they are cast in the linotype machine, are

assembled side by side with their bottom edges resting upon a supporting" table B, which is arranged to slide horizontally in a flat bed plate A supported in the framework A. The table B is provided with side and end flanges B which may be availed of to even up the slugs and to maintain them in proper position.

When thus assembled, the slugs are shifted? longitudinally to bring the ends of their type lines Z up against a straight transverse bar or gage D, which is pivotally mounted upon a pin D supported in the bracket plate D fixed to the sliding table B. The bar Dthus positively and simultaneously efi'ects'the proper transverse a-linement of the type lines at their ends, it being noted that said type lines are carried by raised surfaces Z which engage the bar. This alining action locates the plain edge portions Z of the slugs beyond the bar and s in the roper condition for the trimming action, it being (ibserved that, in the present instance, the slugs are of the same length but have type lines of different lengths and that consequently the plain portions are projected different distances beyond the alining bar, due to the relative shifting of the slugs, as shown in Fig. 3. In this way, all the slugsare disposed so as to be trimmed at one operation and notwithstanding the fact that their plain portions vary in length as just stated. When the slugs are thus disposed, they are pressed tightly together and held up against the end flange B of the table by a clamping jaw B carried thereby and operated by the usual devices B In per gforming the trimming operation,

the appathe table B is moved along the bed plate A so as to carry the slugs sidewise as a whole past an overlying rotary cutter C, provided with peripheral and face cutting teeth 0 and C, respectively, and which thereby trims down or reduces the plain portions Z of said slugs progressively or successively, thus forming therein the recessesZ for the insertion of the printing plate or cut Y, as before described. Fig. 6 shows the slugs as they are about to pass beneath the cutter C and Fig. 7 shows them after they have passed thereby. The cutter is attached to the lower end of a vertical shaft C (see Fig. I

2) rotatably mounted in a sleeve G which is supported between bearing plates A fixed to the free endof a bracket A rising from the framework A and spanning the bed-plate A as shown in Fig. 1. The shaft C may be driven in any suitable manner; in the present instance, it is provided at its upper end with a pulley 0 connected by,

a belt (3 to a second pulley C fixed to the upper end of a driving shaft C receiving motion from some sultable source.

After the slugs have ben trimmed in the manner just described, they are released from the action of the clamping jaw B and shifted, if need be, so as to bring the ends of their body portions into transversealinement, in the manner indicated in Fig. 4. When in this position the recesses Z will be arranged so as to provide a flat supporting surface on the slugs corresponding in outline to the form or contour of the printing plate or cut and upon which it may be sustained at type height. It' is not essential that the alinement of the slugs by their body recelve and support the plate or cut to be inserted. I

As shown inthe drawings, the position of the alining bar D is such as to bring the ends of the type lines close up to the cutter C, so that the recesses Z of the slugs will allow the plate inserted thereon to stand immediately adjacent to the ends of the type lines. However, in some instances it may be desired to locate the plate away from the ends of the type lines, in which event the recesses Z should be cut a corresponding distance therefrom. For this and other reasons, the alining bar D is laterally adjustable upon the supporting pin D so that it can be set at different distances from the cutter C, a screw D being employed to hold the bar in its adjustable position. In this way, when the slugs are shifted longitudinally to bring the ends of the type lines up mounted, is adjustable vertically so as tolocate the cutter at a higher or lower level as required. This adjustment of the sleeve C is effected by means of a surrounding thumb-nut C connected thereto by means of screw threads. The nut is confined against endwise movement by means of a clip C secured to the bracket arm A and fitting in an annular groove in the nut, so that by rotating the latter, the sleeve C will vbe-raised or lowered to the proper extent.

In order to indicate the extent of the adjustment, the nut is provided with a dial plate C coiiperating with a pointer C fixed to the bracket A.

As an alternative construction, the table B wherein the slugs are held may be adjusted toward and from the cutter C. Thus in Fig. 1 the bed plate A is shown as mounted to-slide vertically in the framework A, its adjustment being effected by an operating handle A connectedto one end of a shaft A mounted in bearings of the bed plate and geared to a vertical shaiftA also mounted in fixed bearings of the bed plate and screw-threaded into the framework. The extent of adjustment is indicated bya dial plate A secured to the shaft A and cooperating with a relatively fixed pointer A.

In Fig. 9 the slug Z is shown as having the shoulder at the end of the recess Z undercut, as at Z, so as to receive the beveled edge of a printing plate Y When a series of such slugs are assembled in the form, their undercut walls Z will overhang one edge of the printing plate and thus serve to hold it down in place upon the slugs.

While myinvention is intended primarily to adapt the slugs for receiving and supporting a cut or printing plate, it should be understood that other uses may be made of it which will still be comprised within its spirit. It will frequently be desirable to reploying the precise form of mechanism shown except as limited by the appended claims. Many changes and variations therein will readily suggest themselves to those skilled in the art without departing from the scope of my invention.

Having thus described my invention, its construction and mode of operation, what I claim and desire to secure by Letters Patent of the United States is as follows:
