Specification of Letters Patent.

Patented Oct. 10, 1905.

Application filed November 18,1904. Serial No. 233,326.

To all whom, it 71mm concern.-

Be it known that I, EDWARD B. CLARK, a citizen of the United States of America, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented or discovered new and useful Improvements in Vise- Jaws, of which the following is a specification.

My invention relates to vise-jaws for linotype-machines, and has special reference to an attachment to said jaws which permits the casting not only of the usual linotype-slugs, but also extensions thereof containing a selected dash, sign, mark, and the like. For example, my invention contemplates the casting of a slug having at one end the usual matter for a line of type and at the other end a dash, the latter for use when severed from its companion in separating paragraphs or the like.

My present invention is particularly important as an improvement in a linotype-machine equipped with an attachment constructed in accordance with the claims of Patent No. 75et,970, granted to me March 22, 1904. I contemplate the use of my cutting attachment with the present invention for severing the dash, blank, or the like from the type-containing portion of the slugs. By thus casting the blanks, dashes, &c.. with the usual matter on the slugs I am enabled to cast the former without in any way consuming any extra time. When blanks, dashes, 850., are cast on the ordinary machine, it is necessary to stop the casting of the regular linotype-slugs and devote the whole machine and the time of the operator to their casting. With the present improvement I cast both the dash and the usual reading-matter for a line at a single operation and then sever the two parts of the slugs.

Other advantages and objects of my invention will appear in the following description.

Referring to the drawings, which form a part hereof, Figure 1 is a rear elevation of my improved vise-jaw in connection with its mate and a line of matrices between the jaws. Fig. 2 is a top plan view of the same. Fig. 3 is a cross-section of the improved vise-jaw, taken on the line 3 3 of Fig. 1. Fig. 4 is a view of the compound slug or linotype which may be cast by the use of my invention.

In the drawings, 1 designates the front plate of the usual swinging vise, to which the usual vise-jaw 2 and my improved vise-jaw 3 are secured, the latter being usually adjustable. I show a line of matrices 4 held between the opposing faces of the two vise-jaws. The jaw 3 has the head 5 and the shank 6, which are preferably at right angles to each other. The outer face 7 of this jaw serves to engage one end of the matrices, while its rear face 8 is parallel to the clamping or lower portion of the face 7 and extends down to the shank 6, which is comparatively thin vertically. In line with the die portions of the matrices I place in the head 5 a horizontal hole 9, in which I insert one end 10 of the rod 11, which may extend entirely through the axis of the roller 12. The roller 12 is horizontal or parallel to the shank 6 of the vise-jaw and has its end opposite the head 5 supported on the journal portion 13 of the rod 11. The journal portion 13 of the rod 11, passes through the block or plate 15, detachably secured to the shank 3 by means of the screw 16. 1 1 is a spring seated in a recess in the roller 12, the spring pressing against the block 15 to force the roller 12 tightly against the face 8 to prevent any type-metal from entering between the roller and the said face.

The roller 12 is preferably a polygon in cross-section, or a body having a plurality of plane surfaces parallel to its axis. On selected portions of the faces of the roller I place die-cavities 17, which may have any design appropriate for division or separating marks for printed matter. I have shown several different designs for casting on the slug extensions. When the extensions are to be blank or without any designs or characters on them, one of the roller-faces should be plain.

It will be noted that I have arranged designs for both ends of the roller in order to increase the different designs which I may cast on the slug extensions. Only one-half of the roller would ordinarily be used, and with a hexagonal roller six designs of extensions could be cast by turning-the proper design into alinement with the matrices. If it be desired to use. the designs on the end of the roller nearest the block 15, the roller may be reversed end for end by means of the removability of the block, which can be quickly taken off and put on. The'said roller is designed for use with a casting-wheel having a slot adjustable to various lengths, so as to cast against the matrices only or so much of the jaw and roller in addition as may be desired. Of course my invention can be used for definite lengths with slots of fixed lengths.

In order to maintain the working faces of the roller in the proper plane, I have provided the follower or holder 18, having its lower face conformable to the upper side of the roller when one face of the latter is in a working plane. The follower is yieldingly pressed against the roller by the spring 19, surrounding the pin 20, extending from the follower up through the bracket 21, secured to the face 8 of the head 5. The spring sits between the follower and the bracket and automatically locks the roller in any adjusted position in an obvious manner.

22 represents the slug made by my invention, one end having the usual or any preferred matter thereon (indicated by 23) and the other end having the dash 24 or other preferred design. The dotted line 25 indicates the line on which the slug would ordinarily be out, which can advantageously be done automatically by my patented invention hereinabove mentioned.

The numeral 26 designates the usual plunger which raises the lower ends of the space-bands to wedge the matrices between the jaws 2 and 5.

I do not desire to be limited to the precise form of my invention shown and described, but claim within the same all modifications which employ the general principles thereof. I desire my claims to be interpreted broader than the construction shown except when I use therein a specific term.

Having described my invention, I claim 1. In a linotype-machine, a vise-jaw and a die carried thereon having a plurality of diefaces.

2. In a linotype-machine, a vise-jaw and an adjustable die-carrier thereon.

3. In a linotype-machine, a vise-jaw and a rotatable die-carrier thereon.

4. In a linotype-machine, a vise-jaw, an adjustable die-carrier thereon, and means for holding the carrier in its adjusted position.

5. In a linotype-machine, a vise-jaw, a rotatable device thereon having a plurality of die portions at each end, and means permitting the ends of the said device to be reversed.

6. In a linotype-machine, a Vise-jaw, a clieroller carried thereby and having a polygonal cross-section, and a spring-actuated follower bearing on the roller.

7. In a linotype-machinc, a vise-jaw, and a reversible die-carrier thereon.
