SPECIFICATION forming part of Letters Patent N o. 633,473, dated September 19, 1899.
Application filed May 12, 1899. Serial No. 716,601. (No model.)
To @ZZ whom it may concern:
Be it known that l, HANS OSKAR NIEN.
sTAEDT, a subject of the King of Denmark, residing at 37 Dronning Olgas Vej, Copenhagen, Denmark, have invented a new or Improved Stock and Die, of which the following is a specification.
This invention relates to screw-cutting stocks and dies, the jaws being separable from each other in a simple manner by the rotation of two lock-nuts, so that the return movement of the tool to its initial position can be effected rapidly. By the employment of a rotating guide-disk the operator is saved the trouble of actuating several loose parts when adjusting a fresh guide-hole.
The invention is illustrated by the accompanying drawings, in which- Figures 1, 2, and 4 are respectively aplan, a side elevation, and an end elevation, of the and dies.
At the upper part of the frame 1, Fig. 2, two longitudinal rods 2 and 3 are arranged, between which slide the cutting-jaws 4 and 5 of the die. The rods 2 and 3 are provided with longitudinal slots, in which move the slides 6 and 7. Two guide-keys are inserted into each rod and are kept separate by means of springs 8 S. The slides project laterally through the rods 2 and 3 and fit into grooves made in the jaws 4 and 5. The slides are forced by the springs S 8 against the stop-pins 9 9, iixed in the jaws and 5, the result being that the jaws are permanently pressed apart and made to bear against set-screws 10 10, iixed in the two adjusting-pieces 11 12, which are made to move on pivots 18 13 at the corners of the tool-frame. The adj Listing-pieces 11 V12 are secured in their normal working position by means of two lock-lugs 14 15, which are placed on the ends of a rod carried by the tool-frame. These lugs are provided with helical surfaces bearing on the adjustingpieces 11 12, so thata quarter-turn of one lug locks them in position. Vhen the tool has to be moved back to its initial position, all that is necessary is to turn the lock-lugs, and the adjusting-pieces 11 12, with the jaws 4 5,
Fig. 3 shows a slightly-modiiied stock will be forced apart under the action of the springs 8. The jaws may then be moved clear of the screw-thread produced on the blank.
A spiral spring 1G, placed on the shaft 17, tends to twist it and the lock-lugs 14 15 back to their normal position and to secure them in that position.
Vhen the jaws have to'be exchanged, the lock-lugs are turned around until they disengage from the adjusting-pieces 11 l2, which may then be folded back, so that the jaws are madeperfectly free.
On Fig. 3 is shown a modified arrangement for pressing the jaws apart. spiral springs 8 two V-shaped springs 18 are used. 'Fliese springs keep the jaws apart and work in the same way as the spiral springs.
Having thus described my invention, what l claim as new, and desire to secure by Letters Patent, is-
1. A die-stock, comprisingafraine, slidable jaws therein, springs for pressing the jaws outward and end plates or adjusting-pieces pivoted to the stock at one end and detachablyseeured thereto at the other end, the central portions of said end plates forming stops to limit the outward movement of the jaws.
2. A die-stock, comprising a frame, slidable jaws therein, springs for pressing the jaws outward and end plates or adjusting-pieces pivoted to the stock at one end and detachably secured thereto at the other end, the central portions of said end plates forming stops to limit the outward movement of the jaws, a shaft arranged adjacent to said end plates, and lugs arranged on said shaft and having inclined surfaces to engage the end plates.
3. A die-stock, comprisingaframe, slidable jaws therein, springs for pressing the jaws outward and end plates or adjusting-pieces pivoted to the stock at one end and detachably secured thereto at the other end, the central portions of said end plates forming stops to limit the outward movement of the jaws, a shaft arranged adjacent to said end plates, and lugs arranged on said shaft and having inclined surfaces to engage the end plates, and a torsional spring to turn said shaft and lugs into the locking position.
Instead of the 4. A die-stock comprising a frame having apart, and jaws provided with slots engaged 1o Slots or guideways, slides movable therein, by said slides. springs engaging the slides to press them In Witness whereof I have hereunto set my apart, jaws provided With slots and with liin- I hand in presenceof two Witnesses.
5 itinff-pins both the slots and the pins beinOa T 1 w adapted to be engaged by said slides. b HABS OSKAR NIENSl AEDT' 5. A die-stock comprising a frame having Vitnesses: slots or guideways, slides movable therein, CHARLES HUDE, springs engaging the slides to press them JULES BLOM.
