By @gm 5/ Hmm Patented May 4, 1943 UNETE STATES PATENT OFFICE 1 Claim.

My invention relates to improvements in gripping and holding devices, and particularly to an improved vise having an adjustable stationary jaw adapted to present diiierent shaped faces to the work, and the primary object of my invention is to provide a simplified and eii'icient arrangement of this character which can be readily manufactured in a rugged and serviceable form.

Other important objects and advantages of my invention will be apparent from a reading of the following description taken in connection with the appended drawing, wherein for purposes of illustration I have shown a preferred embodiment of my invention.

In the drawing:

Figure 1 is a general side elevational view of the embodiment.

Figure 2 is a top plan view of Figure 1.

Figure 3 is an enlarged fragmentary longitudinal vertical sectional view taken through the adjustable jaw.

Figure 4 is a bottom plan view of the adjustable jaw.

Referring in detail to the drawing, the numeral 5 generally designates a suitable form of mounting base, preferably circular in shape and provided with circumferentially spaced lugs G through which bolts are adapted to pass to secure the base on a supporting surface. Rising from the base 5 is a rectangular block 'I provided with ya. longitudinal horizontal bore 8 slidably accepting the squared bar 9 of the movable jaw, the portion above the bar 9 being reduced to provide the cylindrical standard IU and the annular shoulder I I surrounding the base of the standard,

as shown in Figure 4 of the drawing.

Swingably mounted on a horizontal pivot I2 in a fan-shaped opening I3 formed in one side portion of the block 'I above the bar 9 is a tear drop shaped detent I4 which is adapted to be engaged in any one of the vertical slots I5 formed in the bottom corner of the rotatable jaw which is generally designated I6 and which has a cylindrical bore I1 rotatably receiving the standard I0.

The adjustable jaw I6 is generally rectangular in plan and has its under part tapered and curved to provide the square bottom surface I9 which rests immediately upon the shoulder Il of the block 'I and is coextensive therewith when the jaw is in one of its adjusted positions. As indicated in Figure 5 of the drawing the slots I5 which accept the detent I4 to lock the jaw in an adjusted position are substantially spaced at the middle of the various sides of the under portion of the jaw I6.

The cylindrical standard I0 is provided with a threaded axial bore to receive a stud bolt y I6 is freely rotatably secured in assembled relation with respect to the block l. The engagement of the detent I with one of the slots i5 prevents any relative rotation of the jaw The four sides of the upper part of the jaw are differently formed so as to be better adapted to holding dierent types of work with respect to the longitudinally movable jaw 25 which is mounted on the bar 9. A vise operating screw 28 provided with a cross bar handle 21 is provided for operating the vise in the usual manner.

The face 29 of the adjustable jaw i6 is angularly indented as shown in Figure 1, the face 30 is longitudinally indented as indicated in Figure 2, the face 3| is straight and plane, while the face 32 has a dual longitudinal indentation, thereby providing four different Working faces for engaging different types of work.

Although I have shown and described herein a preferred embodiment of my invention, it is to be definitely understood that I do not wish to limit the application of the invention thereto,

except as may be required by the scope of the claim.

Having described the invention, what is claimed as new is:

A vise comprising a relatively stationary base, a laterally movable jaw mounted for movement toward and away from said base, said base being formed with a substantially cylindrical standard rising therefrom, a rotatable jaw comprising a substantially rectangular block formed centrally with a bore rotatably receiving said cylindrical standard, the sides of said block presenting different working faces, with the bottom of said block resting rotatably on a portion of the top of said base, said block being formed with vertical slots in the lower part of its sides, said slots opening through the bottom of the block, said base being formed in its sides with a verp tical slot opening through the top of the base,

the slots in said block being registrable with the slot in the base, in accordance with the rotary adjustment of said rotatable jaw, and a vertically swingable latch pivoted in the slot in the base to be swung upwardly into position in the corresponding slot in said block to hold the rotatable jaw with a selected one of its working j faces opposed to said laterally movable jaw.
