SPECIFICATION forming part of Letters Patent No. 728,929, dated May 26, 1903.
Application filed December 8, 1902. Serial No. 134,292. (No model.)
To aZZ whom it WHY/y concern: I
Be it known that 1, JOHN G. JERNBERG, a citizen of the United States of America, and
a resident of the city of Boston, in the county struction and arrangement of parts, which.
will be understood readily by reference to the description of the drawings and to the claims to be hereinafter given. 7
Of the drawings, Figure 1 represents a plan view of a stock embodying the novel features of this invention. Fig. 2 represents a side elevation of the same. Fig. 3 represents an enlarged sectional elevation of the same, the cutting plane being on line 3 3 on Fig. 1. Figs. 4, 5, and 6 represent transverse sections of the same on lines 4 4, 5 5, and 6 6 on Fig. 3; and Fig. 7 represents a sectional plan on line 7 7 on Fig. 3..
In the drawings, 1 is the body portion of a tool-stock embodying the novel features of the invention, the said body portion being provided with handles 2 2 and ears 3 3, to which is pivoted a movable jaw 4. The body 1 is cut away at 5 sufficiently to permit the adjacent surfaces of the jaw 4 and body 1 to be on the center line of the stock, and the free end of said jaw in cross-section conforms in shape to that portion of the body adjacent thereto. The jaw 4 is pressed outwardly by the spring 7, secured to the body 1 by any suitable means. The jaw 4 and the body 1. are each provided with a part of a working tool, here shown as a screw-cutting die 8 9, although it is obvious that other forms of working tools may be used equally as well. The dies 8 9 are secured in the body 1 and jaw 4 by suitable grooves 10 and ribs 11 and are held in position by suitable conical-ended screws 12 13, the conical ends thereof engaging with the walls of depressions 14 15 in the dies 8 9 to force said dies firmly to their seats. The die 8 is intended to be seated permanently in its'seat and is prevented from move ment by the screw 12. The die 9, however, is intended to have a slight adjustment in its seat, this adjustment being obtained by the action of the conical-ended screw 13 on the wall of the depression 15, the amount of movement being regulated by the stop 16, screwed into said jaw in the rear of said die 9. On one hub 17 of said body 1 and adjacent to the free end of the jaw 4 is mounted a sleeve 18, arranged to nicely fit said hub and adapted to be freely moved thereon. The sleeve 18 is provided with a bell-mouth 19, adapted to cooperate with the tapered free end 20 of the jaw 4 and so constructed that when said sleeve is with drawn slightly toward the handle 2 the jaw 4 will be permitted to assume the position shown in dotted lines in Fig. 2, when the toolstock can be removed readily from the tool or other device being operated upon. A slot 21 is out in the hub 17 within the sleeve 18, and a pin 22, extending transversely of this slot, is engaged by the forked lever 23, pivoted to the sleeve at 24 and provided with a thumb-piece25. Acoiled spring26surrounds the pivot-pin 24 and bears upon said lever and sleeve in such manner as to force the sleeve into engagement with the jaw 4. A threaded pin 27 is screwed into said sleeve 18 and is provided with an end 28, which projects into the slot 21 and limits the movement of the sleeve 18 in either direction by coming into contact with a wall of said slot 21. The slot is made of such length as to always prevent the sleeve 18 from disengaging the jaw 4 entirely under normal conditions. It is, however, desirable at times when the dies 8 9 are to be changed to provide for the full opening of the jaw 4. This is accomplished by making the end 28 of the screw 27 eccentric or flat-sided, so that by a half-turn of said screw the flattened side will extend transversely of said slot and permit of a greater movement of the sleeve 18 when the lever 23 is operated, all in an obvious manner.
Beneath the free end of the jaw 4 the body 1 is provided with an adjustable stop-screw 30, which limits the movement of the jaw toward the body portion and causes it to remain in firm contact with said sleeve 18 during the operation of the tool. This screw 30 forms an important feature of the invention,
as without it the parts might soon become worn, and then the jaw would be loose, and as a consequence poor work would be done. The screw 30, however, permits the wear to be taken up and the jaw 4 always to be held firmly when the sleeve 18 is in engagement.
- ting dies are used, for in working back the thread is frequently injured and even destroyed. This causes much waste of time and material, and even when the work can be used it is often imperfect. These objections are entirely obviated by the use of this improved tool-stock.
The operation of the invention is so obvious that it is believed that it needs no further description.
Having thus described my invention, what I claim isv 1. In a tool-stock, the combination of a body portion provided with one part of a working tool, a jaw pivoted to said body portion and provided with another part of said working tool, a sleeve for clamping said jaw to said body, a spring to force said sleeve into engaging position, and means for preventing a ro tation of said sleeve.
