by a great variety of printing faces may be quickly made from such border slugs or from blocks, also whereby various shapes sketched on a sheet of paper or the like may be duplicated as a printing face in slugs w and further duplicates made therefrom.

Other advantages of the invention will appear in the drawings and in the following description. 1 a In the drawings accompanying this speciiication the figures are as follows: Fig. 1-Side elevation of the apparatus showing slugs in holder.

shown in reversed position using but two jaws on carrier clamping slugs.

Fig. 12-Perspective view showing two border slugs as joined when mitered with 4G aid of apparatus.

Before describing the mechanism in detail it should be borne in mind that cast type metal borders or linotype border slugs are what the apparatus is particularly designed to handle for the fashioning therefrom of an almost unlimited number of clifferent printing face designs, and the ap paratus proper is intended for use in connection with a circular saw or other revolving cutter and is positioned upon the saw table but since the saw adjustments do not come Fig. 11Front View of holder with jaws and gains the advantages of the adjustability of the saw table in relation to the saw.

In the drawings 1 denotes a stack of border slugs clamped in a holder-2 mounted on one end ofa drum 3 revolvably supported in a carriage. This carriage takes the form of a square frame 41- embracing the drum at its forward end and a bearing block 5 supporting the threaded shaft 6 projecting from the opposite end of the drum and which 69 frame 4 and block 5 are secured to or formed integrally with a base 7. The frame 4 is provided with a removable top rail 1 to permiteasyremoval of the drum when required.

Base 7 of the carriage is vertically pivoted at 8 to a supporting plate 9 in turn supported on a. base plate 10 in turn supported on a bed plate 11 which may conveniently be thesaw table or bed of a circular saw 12 shown detached in its relative position, but which it is understood is adapt ed for rising and falling in relation to the table like any metal cutting circular saw plate 10 engaged by brackets 16 cast or otherwise secured to plate 10 and one of which brackets is provided with means such as the thumb screw 17 for clamping plates 9 and 10 in positions of adjustment relative to each other.

Means is provided for controllably sliding plate 9 along plate 10 comprising a series of angularly arranged rack teeth 18 projecting downwardly from the upper plate of guide 15 and which teeth are engaged by several similar teeth 19 formed on the end of a flat bar 20 slidable in a channel 21 formed in a raised portion 9 of the supporting plate 9 when the bar is slid back and forth in its channel 21.

The teeth 19 on bar in being drawn across teeth 18 of the guide 15 engage them and force plate 9 to the right or left a distance as determined by the angularity of the teeth and their length until the movement of the bar carries its teeth 19 clear to either side of teeth 18 and upon which plate 9 and apparatus carried by it may be manually moved alon uide 15 to bring any other set of teeth into engagement with the bar teeth, it being understood that the bar device is used for the smaller movements.

Bar 20 is forcibly slid back and forth in its channel 21 by means of a hand lever 22 pivotally connected at 23 to two links 24, 24, link 24 being pivoted at 25 to plate 9 and both links pivotally connected by a cross link 26, the pivot 27 at one end of which cross link also pivots to the sliding bar 20.

The arrangement of bar moving hand lever described equalizes the amounts of travel of plate 9 on plate 10 for given angular movements of the lever as denoted along a scale 28, the lever. striking stops at opposite ends of the stroke when bar teeth 19 are clear of rack teeth 18.

The carriage drum shaft 6 is provided with a milled hand wheel 29 for turning the drum to any required degree and the shaft is provided with a thread 30 for portion (31) of its length, and a plurality of grooves 32 the plane of which is at right angles to the longitudinal axis of the shaft, for another portion (33) of its length, th thread and grooves 32 being engaged respectively by the pointed ends of thumb screws 34, 35 threaded through the bearing block 5, the arrangement being such that upon engaging screw 35 with one of the grooves 32 as shown in Fig. 4, the drum if not otherwise clamped would be free for revolving by the handwheel, whereas if screw 35 is released and screw 34 engaged with the thread 30 the drum will be advanced by turning the wheel. A compression spring 36 reacting between the block 5 and wheel 29 returns the drum to the right upon releasing both screws unless the drum is otherwise clamped.

Means for rigidly clamping the drum at any point of rotation is provided in a thumb screw 37 on frame 4 impinging the forward portion of the drum.

The drum is also provided with a plurality of rows of spaced notches 38, 39, 40 around its periphery for definitely positioning the drum at any point of revolution and holding it by means of one of several pointed set screws 41, 42, 43 extending through an extending arm 44 of frame 4.

The several rows of notches are for calibrating the drum into various divisions. one row being preferably divisible by 3, one

by 5, and one by 7, though other series of divisions may be used if desired.

The divisions or notches of the several rows are consecutively numbered as indicated so that no two divisions of any row will bear the same numbers, but each division will bear a distinct number.

Also provided is a circular scale 45 around which the carriage swivels on pivot 8 and is clamped by a screw 46.

In addition to the above'scales is a vertical scale 47 formed on a fiat bar 48 detachably mounted at 49 to plate 9 and which is to gage certain lines on a diagram in connection with the saw height as will be hereinafter described. This scale has letter characters to avoid confusing with figures of scales on drum periphery.

The slug holder 2 is a square frame composed of four mitered sections as shown best in Fig. 3 each secured to the end of the drum by screws as at 50, extra holes 51 be ing provided so that the jaws may be opened to a larger size frame. Extending through at least two sides of the frame are clamping screws 52 for clamping the slugs in place.

The mitered frame construction permits of removing the jaws and using two only in inverted position as shown in Fig. 11 wherein certain long border slugs 53 are shown clamped between the two jaws.

The forward end of the drum is bored and tapped as at 54 to receive the threaded shank 55 of a sketch or diagram supporting table 56 provided with a face plate 57 made of wood or other material easily penetrated by thumb tacks as at 58 for attaching a. sheet of paper bearing a diagram 59 of the shape of printing face to be made, it being understood that when this device is used on the drum no slugs are in the holder, as this is to get the formula before inserting the slugs.

Cooperating with the diagram plate 57 is a manually operated stylus 60 carried on a sectional arm 61 double jointed at 62 with adjustable friction joints and which arm is carried on a bracket 63 held by screws 64 to plate 11, the screws passing through slots 65 in the bracket so that it may be easily applied or removed. I

Figs. 7, 8 and 9 show a few of an endless variety of forms of printed impressions made from forms made on the apparatus and the dotted rectangle around each impression indicates the body of the slugs below the printing face.

In Fig. 5 a stack of slugs 1 is shown in the holder 2 with a five-sided figure 66 stand ing out from the body of the slugs after forming 011 the apparatus. The rectangular body of the slugs may be reduced to any size after removal from the holder.

In operation of the apparatus the border slugs of any desired face impression, or series arrangement are clamped in the holder, brought into proper relation to the revolving saw by manipulating lever 22 and then advanced with plate 10, so as to cut away the tops of the slugs below the printing face by revolving the handwheel 29 or by moving the carriage with plate 10, or by any combination in succession of both movements.

With a known formula, or succession of figures andletters of the various scales and setting the drum to the figures one after the other and saw to the heightof the letters between cutting, any desired form may be to get its position which is noted, and the diagram swung around for the next portion of the diagram and so on, always noting as well the rotative position of the drum on one of the periphery scales. Thus by placing a stack of border slugs in the holder and working to successive numbers ofthe formula printing face designs may be quickif made of border slugs may be separated,

ly produced and reproduced.

A scale 67 is also provided along the guide 15 useful in special work in connection with the projection of the printing surface of the forms or cuts made, fractions of the divisions may be had on scale 28.

The swivel feature of the carriage permits the hollowing out of rings and portions of rings in the faces of the figures, also for producing a slight pyramidal side wall to the figure to better support frail portions of the printing portions of the slugs in some cases.

By reversing and using but two of the holder jaws as shown in Fig. 11 the ends only of long slugs may be operated upon.

To a man familiar with this kind of work it will be readily apparent that anunlimited variety of printing forms may be very quickly produced, also that any of the forms along the slug junctures to any number of sub-forms, each ordinarily with rectangular bases, thus a circular disk made by rotating the drum a whole revolution against the saw may be divided into two half circles, or several segments straight across the circle, an equilateral triangle into two right angle triangles, and these further into subforms ad infinitum. Also that in setting up display advertising or elaborate border composites where rectangular bases of the forms just a trifle to secure the vertical taper to.

the joint, and the work passed over the saw. One of the chief advantages of the particular rack tooth arrangement within guide 15 is the impossibility of filling it with type metal dust and chips which so easily clogs up screw devices.
