MILLING-MACHINE VISE.
SPECIFICATION forming part of Letters Patent No. 419,072, dated January 7, 1890.
I Application filed December 6, 1888. Serial No. 292,846. (No model.)
To aZZ whom it may concern: lesseningthenumber of jaws required in any Be it known that I, FRANCIS H. RICHARDS, particular case has on the inner end thereof a a citizen of the United States, residing at swivel-jaw 10, pivoted in the center thereof at Hartford, in the county of Hartford and State 11 in a slot 12, formed in said sliding jaw N.

The forward part of the bed B is chan- 6o [0 ers for use on milling-machines, metal-planers, neled, as at 15, to receive a series of thrustand multiple drills, and on other machines in blocks D and a corresponding series of which the pieces to be operated upon should wedges E, through which said blocks are operbe simultaneously clamped at several points ated.

The block D bears 011 0 place the piece A to be operated upon.

Each clamp-jaw N as a means for amount of longitudinal movement, the block ,of them, the jaws N are extended forward over the said wedges and blocks, this extension being designated by 30 and containing a spring 31 for retracting the jaw. A plug 32 slides in the spring-receiving hole in said part and bears against the abutment 33 of the cap P, which covers the entire series of jaws and their operating devices. A screw 34 closes the outer end of the said bore in extension 30. By means of this construction the distance 35 may be quite short without permittingthe jaws N to be cramped in their ways by the movement under pressure of the blocks D against said jaws, and also the otherwise necessary width of the vise is materiall y reduced.
In preparing to use the vise the position of jaw G is first adjusted by suitable blocking at 2, so that only a slight movement of the jaws N is required. The piece A being then laid on said stationary jaw, the wedge E. is forced along until all the jaws N are driven out with a force sufficient to properly retain said piece A in place. A fixed stop 40 is usually provided for locating the piece A longitudinally of the vise.
Having thus described my invention, I claim 1 1. In a work-holder, the combination, with the bed-plate, of the fixed jaw, the clamp-jaws, the thrust-blocks bearing on said clamp-j aws, wedges intermediate to said blocks, and means, substantially as described, for sliding the wedges and blocks, the abutting surfaces substantially as described, all
of the wedges and blocks being inclined to their lines of motion, all substantially as described.
2. In a work-holder, the combination, with the bed-plate having a fixed jaw, of the clampjaws, the blocks D, wedges E, and means, substantially as described, operating the wedges and blocks, said blocks and the intermediate wedges having their opposite ends inclined in opposite directions, substantially as described.
3. In a work-holder, the combination of a bed-plate having cap P, the jaw N, means, substantially as described, adapted to force out said jaw, and the spring in said jaw arranged to retract the same, substantially as described.
4. In a work-holder, the combination of the bed-plate, the jaws N, having extensions 30, the series of blocks D, bearing on the faces 25 of said jaws, and wedges, substantially as described, operating said blocks from the movement of the first wedge, substantially asdescribed.
5; In a work-holder, the combination of the fixed jaw, the movable jaws arranged to move crosswise to the fixed jaw, the screw arranged to actuate the slide lengthwise to said fixed jaw, and intermediate blocks and wedges,
coacting substantially as described.
6. The combination, with a bed-plate and the sliding jaw, of the fixed inclined ab utment E the thrust-block D and the wedge E all substantially as described.
