Specification of Letters Patent.

Patented Nov. 26, 1912.

Application filed January 5, 1912. Serial No. 669,649.

To all whom it may conce/m:

Be it known that I, JosnrI-r Rans, a citizen of the United States, residing at Schenectady, in the county of Schenectady and State of New York, have invented new and useful Improvements in Vises, of which the following is a specification.

This invention relates to vises, and one of the principal objects of the invention is to provide a. simple, durable, and cheaply constructed vise, in which, by slight movement of the operating handle, the clamping screw may be released and the outer or movable jaw will be carried automatically into' engagement with the work or with the stationary jaw.

A further object of the invention is the provision of novel means for mounting the vise upon a bench or support, in such a manner that it is adaptable for revolution on the support, and may be locked firmly in any adjusted position.

Another object of the invention resides in the provision of a novel forni of locking mechanism which prevents rotation of the vise upon its support under ordinary circumstances, and auxiliary locking mechanism which is adapted to be brought into play when it is necessary to use the vise for heavy work.

A still further object is the provision of novel means for clamping the vise upon a table or support which obviates the use of thumb screws and like devices, and at the same time makes the device readily removable.

Further objects of the invention will appear, as the following specific description is read in connection with the accompanying drawings, which form a part of this application, and in Which:

Figure 1 is a longitudinal vertical sectional view taken through the vise. Fig. 9. is a horizontal section taken on the line 2-2 of Fig. 1. Fig. 3 is a plan view of the mounting plate. Fig. L is al vertical sectional view taken on the line 4 4 of Fig. 1. Fig. 5 is a similar section on an enlarged scale, showing only the threaded cylinder. Fig. G is a side elevation of the device applied to a table and with parts broken away. Fig. 7 is a detail elevation of the screw cylinder removed and with parts broken away.

Referring to the drawings by numerals, and more particularly to Fig. 1, 1 represents a mounting plate which is suitably secured to a table, bench, or other support, and is provided with an annular groove or channel 2 in its upper face, and a ball-race 8, both of which will be hereinafter described. r1`he plate 1 is provided with a central aperture L1, and passing through the central aperture is a clamping screw 5 which is carried by or formed integral with the base 6 of the vise. Rising from the base is the usual stationary jaw 7 having an anvil 8 formed thereon and being provided with a pair of apertures 9 arranged in parallelism to receive the guiding arms 10 and 11 of the movable jaw or member 12. Between the apertures 9, the stationary jaw is provided with a threaded aperture 18, in which is adjustably mounted an externally threaded cylinder 14 having a central bore 15 with threaded

sections

17 and 18 upon opposite sides thereof. Passing through the cylinder is an operating rod 19 which is dat on its two opposite sides, so as to freely slide between the threaded

sections

17 and 18, and upon the other sides is provided with threads 20, the grooves of which are interrupted by webs 21 extending thereacross. The rod is provided with a smooth portion 22 which extends through the movable jaw and is provided with an apertured head 23, in which is slidablyT mounted the ordinary operating handle 24. When this' operating handle is turned, so as to bring the fiat sides of the rod 19 adjacent to the threaded

sections

17 and 18, the rod may be moved freely in or out of the cylinder, as will be readily understood. YV hen the rod is turned in the proper direction, the threads 20 will engage the threaded

sections

17 and 18, until limited by the webs 21, at which time the cylinder will be caused to turn in the proper direction to draw the movable jaw toward the stationary jaw. lVhen the rod 19 is turned in the position just described, the movable jaw is carried automatically toward the stationary jaw by means of a spring 25 which is connected to both the movable and stationary jaws, and when the movable jaw is closed upon the stationary jaw the said spring lies within recesses 26 formed in said jaws. The operating rod is prevented from relative longitudinal movement through the movable jaw by means of a collar 27 which is secured to the rod and is engaged by a plate 28 removably secured to the stationary jaw. Mounted in the base of the stationary jaw and vertically slidable in the same, is a headed rod 29, upon the upper end of which is pivoted a cam lever 30 adapted to bear against the base and draw the vhead of the rod into engagement with the shoulder 3l formed in the groove or channel 2. This effectually locks the device to the mounting plate against all ordinary strains, but when it is desired to lock the vise against excessive strains, an arm 32 which is pivoted to the base 6 is thro-wn into engagement with notches 33 formed around the edge of the mounting plate. To further secure the vise against rotation, the clamping screw 5 has threaded thereon a clamping lever 34 which is adapted to draw the base of the vise into engagement with the mounting plate. The ball race 3 is duplicated, as shown at 34, in the base 6, and balls 35 are interposed. to cause the vise to rotate readily upon the mounting plate, when the lockingl members are released.

The table vise, shown in Fig. 6, has a stationary jaw provided with a dove-tail stud 36 on its lower end adapted to enter a similar aperture 37 in a clamping plate 38, and to wedge therein, as will be hereinafter described. The clamping plate is provided with a continuation at right angles, shown at 39, which continuation is provided with a lateral offset intermediate of its length, as shown at 40. Immediately above and below the offset, there are secured

suitable sleeves

41 and 42, in which is slidably mounted a rack bar 43 adapted to be engaged by a toothed pawl 44 normally held in engagement with the rack bar by a spring 45. This pawl is pivotally connected to an operating lever 46 by means of a link 47, and also similarly connected to a release lever 48 through links 49. By operating the release lever, the pawl may be withdrawn from the rack bar, and the same may be forced into engagement with the under side of the table; then by forcing downwardly upon the operating lever 46, the rack bar may be advanced in the sleeves, so as to pull the clamping plate 38 down against the upper side of the table, thereby forcing the dove-tail head 36 wedgingly into engagement with the aperture 37. This locks the vise against rotation and also holds the same upon the table. Then the operating lever 46 is thrown down to operative position, the pivot point of the link 47 on said operating lever is off center, thus locking the lever 46 against retrograde movement.

When it is desired to use the device for operation upon a plurality of pieces of the same character, it is found advantageous to limit the outward movement of the movable jaw, and to this end the arm l1 is provided with a plurality of apertures which are adapted to be engaged by a pin 5() carried upon the end of a chain 5l which is connected to the base 6. The pin 50 extends across the arm when inserted in one of the apertures, and engages the stationary jaw, as will be readily understood.

What is claimed is:

l. In a vise, a stationary jaw member, a movable jaw member slidably connected therewith, a cylinder threaded in the stationary jaw member, a screw journaled in the movable jaw member and having mutilated threads to engage the cylinder, and means carried by the screw for rotating the cylinder.

2. ln a vise, a stationary jaw member, a movable jaw member slidably connected therewith, a cylinder threaded in the stationary jaw member and having internal disconnected thread sections, a screw freely journaled in the movable jaw member, and

means carried by the screw for limiting the engagement of its threads with the thread sections of the cylinder.

3. In a vise, a stationary jaw member., a movable jaw member slidably connected therewith, a cylinder threaded in the stationary jaw member and having internal disconnected thread sections, a screw freely journaled in the movable jaw member, means carried by the screw for limiting the engagement of its threads with the thread sections of the cylinder, and a spring interconnecting the movable and stationary jaw members.

4. In a vise, a stationary jaw member, a movable jaw member slidably connected therewith, a cylinder threaded in the stationary jaw member and having internal disconnected thread sections, a screw freely journaled in the movable jaw member, and ears bridged across the threads of the screw for limiting the engagement thereof with the thread sections of the cylinder.

5. In a vise, a stationary jaw member, a movable aw member slidably connected therewith, a cylinder' threaded into the stationary jaw and having internal disconnected thread sections, a screw freely journaled in the movable jaw member, said screw having mutilated threads and flat sides, and webs connecting the threads at one end for engaging the disconnected thread sections to f limit the movement of the screw within the cylinder.

In testimony whereof T afliX my signature in presence of two witnesses.
