`9 Claims.

, The invention here disclosed relates to vises and particularly though not exclusively to those `of a type suitable for holding the workin milling r, machines.

Objects or the invention are to provide a quick acting vise, which can -be readily set for -holding work of different size, which in the holding position will have a high pressure factor, which will be automatically stopped to lock in the high pressure holding position, which will automaticallyhold in the adjusted position all the more firmly with increase of pressure on the stud which holds the vise set,v for dierent sizes of, work and which with these and various other desirable attributes lwill be of relatively simple, substantial construction and consisting of but few parts.

The foregoing and other objects are attained by certain novel features of construction, combinations and relations of parts hereinafter described and broadly claimed.

, The drawings accompanying and 4forming part of the following speciiication illustrate one of the present practical commercial embodimentsof the invention. The structure however may be modied and changed as regards this disclosure all within the true intent of the invention, as will` be apparent from the scope of the claims.

Figs. l and 2 are top plan .views illustrating the invention embodied in the form of a milling machine vise and showing it in open and closed or substantially closed positions.

Fig. 3 is a longitudinal sectional view ason substantially `the plane of line 3--3 of Fig. 1.

Fig. 4 is a cross-sectional view on substantially the plane of line vIl---i of Fig. 3.

Fig. 5 is a broken and part sectional detail illustrating the eccentric jaw closing mechanism.

In the embodiment illustrated, the basel, of the vise is designed for mounting on a milling machine table and for that purpose is shown as of relatively'flat elongated design, carrying a iixed jaw 8, at one end and recessed at 9, to take the bolts for fastening it down on the milling machine.

'Ihe movable jaw is shown at ID, slidable to- 'ward and away from the fixed jaw over the flat trackway I I, guided thereon by dependent flanges I2, reaching down over the side edges ofthe track as in Fig. 4 and confined in such relation by retainers I3, bolted to such dependentflanges and extending inwardly beneath conning shoulders I4, of the base. f

`Quick opening and closing jaw movements are effected in the illustration by means of a hand (Cl. s-60) f lever I5, pivoted on a bushingor spacer sleeve I6, Fig. 3 and having an eccentric portion I1, Fig. 5, encircled by one end of a push link I8, which has its opposite end pivotally engaged with a pin I9, set in the movable jaw. This eccentric link is shown as supported on a shouldered portion 20, on the lever at the base of the eccentric and as loosely confined in this relation by a washer 2l, resting on tcp of the sleeve I6, Figs. 3 and 4. Ar the opposite end, the link 10 enters through a recess 22, in the end of the movable jaw. The pivot pin I9, is shown in Fig. 3, as `extending across the cavity 22, in the end of the jaw and as having a head 23, at the lower end of the same seating in a corresponding 5' opening in the lower face of the jaw, such head. sliding over the surface of the track Il, which latter thereby prevents escape of the pivot pin.

The eccentric jaw operating means disclosed provides a positive high pressure closing of the jaw and the hand lever enables quick easy operation of such means for either jaw closing or opening movements.

A shoulder 24, on the hand lever by engagement with the rear face of the movable jaw at 25, 25 Fig. 5, limits the jaw closing movement of this lever and these cooperating parts are preferably so arranged as to engage just before the eccentric reaches the extreme limit of travel. This prevents the high point of the eccentric from passing the dead center position, thus to stop the parts in a locked relation just beforereaching the extreme limit of travel, where pressure is practically at that maximum which is possible at the eXtreme end of eccentric travel. 5

For adjustment of the vise to different size pieces, the eccentric pivot is made adjustable, inv the illustration by providing a bolt 26, carrying the pivot bushing I6. This bolt is shown as having a rectangular head portion 21, slidably o and non-rotatably held in an intermediate slot 28, in the guide II, and below that a widened or laterally extended head 29, engaged in the wid.- ened undercut groove 30. A nut 3|, on the upper g1 screw-threaded end of the bolton the washer 2l, to force the pivot bushing I l,A down on the track II., and to draw the head 29, on the lower end of the bolt firmly up against the roof 32, of thev l undercut slot 30. By loosening nut 3|, the whole 50 movable jaw assembly can be quickly shifted one way or the other to suit the size of piece to be held and by simply tightening this nut, the parts can be secured in position where the handle can he `usedtappe-mand close `the movable jaw tol 55 release or to secure work of that particular size. To lock the pivot stud in the position to which it is set, the undercut slot or at least the upper shoulders 32, of the same are inclined downwardly away from the vise jaws on a slope such as represented by the line 33, Fig. 3 and the coacting upper face of the abutment head 29, is similarly inclined, thus to cooperate with a wedging eiect upon application of jaw closing pressure. Stated differently, the thrust of the jaw closing operation tending to shift the pivot stud away from the xed jaw serves to bind the coacting wedge faces of the bolt head and undercut groove all the more iirmly together. The reaction is a force enough to withstand any such action. Any tendency to slip will be. immediately stopped by a wedging self-tightening cooperation of the parts.

The parts are proportioned so that the bushing will act as a spacing sleeve seating rmly down on top of the track II, while leaving the lever free vto oscillate thereon between said track at the bottom and the washer 2l, at the top.

Similarly, the link I8 is left free on the leccentric I'Lbetween the shoulder 20, on the hub of the lever and said conning washer 2|.

Upon sufliciently loosening a nut 3 l the handle assembly with the attachedvmovable jaw can be entirely withdrawn from the track portion of the base and whenrso removed, the pin I9, can be dropped or knocked out to release the movable jaw, thus to enable the ready substitution of a 45 on, the movable jaw is utilized to effect a morel secure holding of the vise in the adjusted position to vwhich it has been set andany tendency to slip is made effective to automatically secure these parts the more rmly. 50 i What is claimed is: I

1. In a vise of the character disclosed, cooperating relatively movable jaws, an eccentric for applying ijaw closing pressure and an vad'- justable mounting for said eccentric including a .55 support having a face inclined at a` slightangle in respect to the j'aw movement and a mounting stud for said eccentric having an abutment head in clamping engagement'with said face` and the inclination of said face being divergent in respect 60 to' the jaw movement in the jaw opening direc.
