VISE.

I Specification of Letters Patent. Patented June 29, 1915.

Application filed January 20, 1915. Serial No. 3,331.

To all whom it may concern:

Be it known that we, THoMAs J FneLnY and Gnonon O. LEOPOLD, citizens of the United States, and residents of Philadelphia, county of Philadelphia, State of Pennsylvania, have invented certain Improvements in Vises, of which thefollowing is a specification.

Our invention relates to certain improvements in vises such as illustrated in our application for patent filed June 10th, 1914, under Serial No. 844,253. A vise of this type can be used either as a swiveled bench vise or as a machine vise. When used as a bench vise one jaw is the fixed jaw, and when used as a machine vise the other jaw is the fixed jaw.

One object of our invention is to improve the detail construction of such a vise of the above type so that it will be more substantial than the Vises of this type now on the market.

A further object of the invention is to so design the parts that they will be simple and can be easily assembled.

In the accompanying drawings :Figure 1, is a longitudinal sectional view of our improved vise; Fig. 2, is a transverse sectional view on the line aa, Fig. 1; Fig. 3, is a sectional plan view on the linebb, Fig. 2; Fig. 1, is a detached perspective view of the means for securing the adjusting screw to the fixed jaw 01": the vise; Fig. 5, is a detached perspective view of one of the notched bars; Fig. 6, is a detached perspective view of the tapered washer located in the base plate; Fig. 7, is a transverse sectional view on the line 0c, Fig. 8, illustrating a modification of the means for fastening the bars to the fixed jaw; Fig; 8, is a sectional view on the line cl-cl, Fig. 7 Fig. 9, is a perspective view of the swivel plate usedin connection with the jaws; and Fig. 10, is a perspective view of a grooved plate which may be used in connection w1th the vise, for holding round sections.

1 is the base of the vise having a flange in which are the openings for the screws, by which it is secured to the work bench, or other support. In the base is a conical opening, and mounted in the opening is a disk 2 and located between the disk and the base, in

disk 2 so that, when the bolt is turned in onedirection, the swivel section is firmly secured in any position desired to the base, but by backing oil the screw the swivel section can be turned on the base.

In the swivel section is an opening 6 of sufficient size fora handle 7 which is shaped to fit over the head 8 of the bolt 5. This handle projects at one side of the vise so that on moving the handle in one direction or the other the swivel section can be held or released. A screw 9 in the swivel section 1 extends over a flange of the handle 7, as illustrated in Fig. 2, so as to prevent the withdrawal of the handle without first backing cit the screw. The swivel section has a seat at each side thereof on which are two projections 10 and 11. The inner surface of the projection 10 is beveled as shown in Fig. 1, and mounted in the recess between the two projections is the body portion 12 ofv the fixed jaw which is held in position by a set screw 13 adapted to a threaded opening in the projection 11. The upper end 14 of the fixed jaw is shaped to form the jaw proper of the vise,which may be of any type desired.

15 is the movable jaw of the vise, in the present instance, and has an extension '16 open at the center to pass on each side of the fixed jaw. This extension is located above the projecting portion 17 of the swivel section of the vise, as clearly shown in Fig. 2, and it is not only guided by the projections 10 and 11, but also by the portion 12 of the fixed jaw.

In order to hold the movable jaw firmly to the swivel section and to the fixed jaw, we provide two long bars 18, Fig. 5, which are adapted to grooves 19 in the body portion ofthe vise. These bars are notched as shown at 21 and are held from moving longitudinally in the grooves 19 by screws 20, Figs. 2 and 3, which are adapted to thread ed openings in the body portion of the fixed jaw and extend into the notches 21 in the bars. In some instances, instead of the screws, the bars may be held by a winged washer 24, the wings of the washer extend ing into the notches in the bars, as illus-v trated in Figs. 7 and 8; the washer being heldin place by a screw 23. The bars hold the movable jaw firmly against the under surface of the fixed jaw so as to provide a neat and accurate fit'of the parts.

, 26 is a feed screw-adapted to thethreaded opening in the bearing 27 carried by the movable jaw, and this feed screwhas a head 28 and, in the present instance, a sliding handle 29 is used. The innerend of'the feed screw passes into a cavity-30in the fixed jaw, the end of the screw resting against the base of the cavity, and in this screw is an annular slot' 31 in which fits a U-shaped key 82 and screwed into the threaded portion of the opening 30 in the fixed jaw is a threaded sleeve 33 which clamps the key 32 against a shoulder 34 and thus holds the end of the screw in position in the fixed jaw but allows it to turn freely therein. The sleeve 33 is slotted as shown, so that it can be readily turned by a screw driver or other instrument.

In some instances the surfaces of the jaws may be plain, but we prefer to provide a recess 35 in the fixed jaw for the reception of the pivot pin 36 of a swivel plate 37, Fig. 9, which may bejinserted vbetween the jaws when it is desired to hold uneven pieces,and

we also provide a plate 38, Fig. 10, having transverse grooves 39 and vertical grooves 40, which can be located between the jaws for the purpose of holding round work. 7

As shown in the drawings, the vise is of the swivel type, but on backing off the screw 13 the fixed jaw may be detached from the swivel section 4 and then the vise becomes a machine vise and, in this case, the fixed jaw becomes the movable member. s

The body portion of thefixed jaw is less in depth than the body of the movable jaw, so that, when the vise is detached from the swivel section and is placed on a fiat surface,

the jaw 14: can be readily moved. The jaw 15 is fiat at each side and at one end so that G'opies. ofthis patent may be obtained for it can be placed in several different positions on the bed o'fa vdrill or other machine.

We claim V 1. The combination in a vise, of a fixed head; a movable head slidably mounted on the fixed head; an adjusting screw adapted to a threaded opening in a bearing in the :sliding head and having its inner end grooved and fitting a cavity in the fixed head; a key fitting the groove; and a threaded sleeve adapted to the opening in the fixed head and bearing against the key so as to retain the screw in the fixed head.

2. The combination in a vise, of a head having a recess therein; an adjusting screw having a groove near one end and resting against the base of the recess; a shoulder in the recess; a washer adapted to the groove in the endof the adjusting screw; and a sleeve clamping the washer against the shoulder.

3. The comb1nat1on in a vise, of a aw; an

"adjusting screw, the jaw having a shouldered recess therein, the walls of the recess being threaded, the end of thescrew resting against the base of the cavity and having an annular groove therein; a U-shaped washer adapted to the groove; and a threaded sleeve mounted in the recess and clamping the washer against the shoulder.

' 4. The combination in a'vise, of a fixed head and a movable head arranged to slide on the fixed head, the body portion of the fixed head having a groove on each side thereof; a notched bar mounted in each groove; with two screws located in the fixed head, one screw extending into the notch of five cents each, by addressing the Gommissionerof raten t s,
