SPECIFICATION forming partof Letters Patent No. 726,441, dated February. 1i), 1903.

7 Application filed August 18, 1902. Serial No. 120,121. (No model.)

T0 at whom itmctyconccrnq Be it known that I, GEORGEA. KENNER, a citizen of the United States','re'siding at East St. Louis, in the county ofSt; Clair, State'of Illinois; have invented certain new and use-. ful Improvements in- Die Sockets, of which the followingisaspecificatiomreference being had therein to the accompanying drawings.

This invention relates'to'a die-socket, and

particularly to a device for mounting a screwthreading die in a stock so asto permit the adjustment thereof. v

The invention has for an object to provide an improved construction of adjusting means adapted tosupportand carry a cutting-die and a guiding-dieso as to permit the reciprocation thereof, but to prevent a rotarymovement of the diesupon their pivot.

Other and further objects and advantages of .the invention will be hereinafter set forth, and the novel features-thereof defined by the appended claims.

lnth'e drawings, Figure 1 is a plan of the invention Fig. 2, avertical section on the line 2 2 of Fig. 1; Fig.3, a plan of the stock; Fig. 4,"a plan of the guiding-die; Fig. 5, a similar view of the cutting-die, and Fig. 6a detail perspective of the sliding block for supporting both dies. 1

Like letters of reference refer to like parts inpthe several figures o'f-the drawings.

The letter A- designates a stock of any desired configuration and providedat opposite ends with the; usual handles A, which, are shown as broken away inthe drawings. The

central body of the stockis provided with anelongated aperture A and upon one face thereof at the opposite ends a curvedwall A is provided, while upon the opposite face a similar wall A is formed fromthe body of the stock. At each end of the elongated opening A a recess A is provided, which is adapted to receive the lug'B, projectingfrom the sliding block B. This block is of substantially equal diameterto the aperture A and provided with tapered walls adapted to slide longitudinally therein as the dies carried by the block are adjusted. The block is provided with a central aperture B (see Fig. 6) and with a series of tapering pins B adapted to pass through similar apertures 0, formed in the body of the cutting-die O, and which rests pins project. The end of the block opposite to the lug B is provided with a curved face [Bf to present a clearance for any material opcuringscrew D maygbepassed, and one end iof the aperture is countersunk to receive the head Dof this screw and present a flush surfaeeQwhile the opposite end'of the screw is threaded, as;at D and engages a threadedso'cket E'g'fo'rmed centrally within the guidingupon the face of the block from which the die E, whichis thereby clamped against the v opposite side of the block B from the die 0. The cutting-die O is provided upon its periphery with a series of cutting-threads C the same 'b'eing'of different pitches, so that the die when rotated in connection with its associate membermay be adjusted to present cutters for different characters and pitches of threads. The guiding-die-E is provided with a similar series of cut-away recesses E upon its periphery, which correspondin size with those, upon the cutting-die and hold or guide'the materiah'such as the bolt or pipe passing through the socket, so as to secure a perfectly straight out and most desirable form.

3 of thread.

As shown in Figs. land 2, two sets of dies and sliding blocks are mounted in the stock, and for the purposeof securing the proper adjustment upon'th'e work these are adapted to be adjusted bymeans of set-screws F, threaded in the end walls A and provided with lock-nuts F for holding the screws at their adjustment. These screws bear against the body of the die 0 and adjust the same longitudinally of the stock, as is customary in this art, and it will be observed that the movement of 'thedie carries with it the sliding block B and guiding-dieE, so that all of the parts are adjusted, while the dies are prevented from rotation by means of the lockingpins upon the block B,which is also positively guided in its movement by the lug B" thereof traveling within the recess A at each end of the elongated aperture. In removing or adj usting the dies to secure the different threads it is only necessary to loosen the bolt D, when both of the dies can be turned or adjusted and reengaged with the pin of the sliding-block.

It will be obvious that changes may be made in the details of construction and configuration without departing from the spirit of the invention as defined by the appended claims.

Having described my invention and set forth its merits, what I claim, and desire to secure by Letters Patent, is

1. In a die-socket, a stock having an elongated aperture therein,a sliding block mounted to travel in said aperture, a cutting-die upon one face of said block, and a guidingdie secured to the opposite face thereof; substantially as specified.

2. In a die-socket, a stock having an elongated aperture therein,a sliding block mounted to travel in said aperture, a cutting-die upon one face of said block, a guiding-die secured to the opposite face thereof, means for adjusting said block longitudinally of the aperture, and means for adj usting said dies rotatably upon said block; substantially as specified.

3. In a die-socket, a stock having an elongated aperture therein, sliding blocks disposed at the opposite ends of said aperture, cutting-dies carried by said blocks, and guid ing-dies secured to the said blocks upon the opposite face from said cutting-dies; substantially as specified.

4. In a die-socket, a stock having an elongated aperture therein, sliding blocks disposed at the opposite ends of said aperture, cutting-dies carried by said blocks, guidingdies secured to said blocks upon the opposite face from said cutting-dies, projecting lugs from said blocks adapted to enter recesses at the ends of said aperture, and means for adjusting said blocks longitudinally of the aperture; substantially as specified.

5. In a die-socket, a stock having an elongated aperture therein, sliding blocks disposed at the opposite ends of said aperture, cutting-dies carried by said blocks, guiding dies secured to said blocks upon the opposite face from said cutting-dies, projecting lugs from said blocks adapted to enter recesses at the ends of said aperture, means for adjusting said blocks longitudinally of the aperture,

and holding-pins upon one face of said blocks adapted to enter openings in the body of the cutting-dies; substantially as specified.

6. In a die-socket, a stock having an elongated aperture therein, sliding blocks disposed at the opposite ends of said aperture, cutting-dies carried by said blocks, guidingdies secured to said blocks upon the opposite face from said cutting-dies, projecting lugs from said blocks adapted to enter recesses at the ends of said aperture, means for adjusting said blocks longitudinally of the aperture, holding-pins upon one face of said blocks adapted to enter openings in the body of the cutting-dies, and a securing-bolt for said dies passing through the cutting-dies and blocks and threaded into the guiding-dies substantially as specified.

7. In a die-socket, a stock having an elongated aperture therein, sliding blocks disposed at the opposite ends of said aperture, cutting-dies carried by said blocks, guidingdies secured to said blocks upon the opposite face from said cutting-dies, projecting lugs from said blocks adapted to enter recesses at the ends of said aperture, means for adjusting said blocks longitudinally of the aperture, holding-pins upon one face of said blocks adapted to enter openings in the body of the cutting dies, a securing-bolt for said dies passing through the cutting-dies and blocks and threaded into the guiding-dies; end walls concentric to one face of said cutting-dies, and set-screws adjustably mounted in said walls to bear upon said cutting-dies; substantially as specified.

8. In a die-socket, a stock provided with a central elongated aperture and die-seats upon its opposite faces, a sliding block mounted within said aperture, dies upon the opposite faces of said blocks and disposed within said seats, and means for securing said dies to said block; substantially as specified.

Intestimony whereof I affix my signature in presence of two witnesses.

GEORGE A. KENNER.
