VISE.

Application filed January 26, 1924. Serial no. 628,851.

My invention relates to improvements in vises and more particularly to Vises of that character adapted to be used on horizontal benches.

Explanatory to the invention I will state that in the usual type of Vises it is impossible to vertically insert a rod or pipe more than a few inches into the jaw before coming into contact with the vise screw. In practically in all bending operations where the angle formed is over four or five inches from the end of the object being bent, it is necessary to place the object horizontal between the jaws which gives a poor purchase and -an awk- 3; ward pull or pressure, and when hammering is necessary, it must, in such cases, be on the end of the jaws and therefore, requires a horizontal swing of the hammer. It will be further stated that the usual type of vise 9 requires vertical supports and changes of adjustment from large to small opening between the jaws is slow when made entirely by means of a screw.

In view of these objectionable features, it has been the object of this invention to provide a vise that has a vertically unobstructed space between the jaws practically the width of the vise, also to provide a vise that can be adjusted quickly to any size of object within its limits and whose jaws open and close without any change of angle.

In accomplishing these and other objects of the invention, I have provided the improved details of construction, the preferred forms of which are illustrated in the accompanying drawings, wherein- Figure 1 is a perspective view of the vise embodied by the present invention; a part of the casing being broken away for better illustration.

Figure 2 is a vertical cross-section longitudinally of the vise.

Referring more in ings- 1 designates a horizontal bench on which a vise embodying the present invention is mounted. The vise, in its preferred construction, consists of a base or casing 2 provided at its opposite sides and inner end with projecting flanges 3, through which screws or bolts, as at 4:, may be extended to anchor the device to the bench. The outer end face of the casing presents a fiat,'vertical surface 5, and this ordinarily would be placed flush with the edge of the bench. On this end of the casing there is integrally detail to the drawformed a jaw 6' of considerable width and this j aw preferably has a rear face farmed after the fashion of an anvil.

Slidably mounted within the casing in parallel relation and adapted to be adjustably extended from the end face 5 are two spaced apart rods 7 and 8, which, at their outer ends, are attached rigidly to a cross head 9 and along the upper surface of their inner end portions are provided with rat-"c11 et teeth 10. These ,rods may be shifted inwardly or outwardly within the casing and may be locked at different positions of ad justment by means of a block 11 that is fitted within a transverse openin 152' in the top i'vall of the casing 2, and Wl ich has teeth 13 on its. under surface adapted to opposedl'y engage the teeth 1o. A bolt, 14 is liked in the bottom wall" of the casing and extends vertically upward through opening centrally in the bloci-r l1 and, at its upper end, is pivotallyconnected witlrthe head portion o'fa locking lever 15'; the lever being provided with an eccentric head 16 that is adapted to engage with the top face of the block when the lever is moved downwardly to thereby press the block and hold it in" locked relation with the teeth of the rods 7 and S to thereby prevent movement of the rods outwardly. hen the lever is swung upwardly, a spring 17 that is coiled about the bolt 14 and which bears against the under side of the block 11, lifts the latter free of the teeth 10 of the two rods and they may then be adjusted inwardly or outwardly.

Slidably mounted on the outer ends of the rods 7 and 8 is a vise jaw 20 and this corresponds in width to the Width of the fixed jaw. A screw '21 is threaded centrally through the cross head 9 and this, at its inner end, has a revolubly fixed connection with the jaw 20, and at its outer end has a cross rod 23 extended therethrough whereby it may be rotated to cause the movable jaw to be adjusted from and toward the fixed aw.

Assuming that the device is so constructed, in using the same the lever 15 is first moved to vertical position so that the spring'l'? may lift the locking block 11 free of the teeth of the rods 7 and 8 so that these latter rods, which are carriers for the movable jaw, may be freely adjusted. The object to be operated on is then placed within the jaws and the movable jaw is properly adjusted with respect thereto, and

the lever 15 moved downwardly to look the carrier at this adjusted position. Any play or looseness may then be taken up by a slight turn of the screw 21 which will adjust the movable jaw along the carrier. A slight backward turn of the screw releases the pressure on the jaws. In this construction the screw 21 has a movement of two or three inches and this is SUlfiClQIll) to take care of small adjustments so as not to require use of the eccentric lever, except where greater adjustments are requlred.

If it should be so desired, the casing 2 could be mounted upon a bench with its fixed jaw spaced inwardly from the edge of the bench and an opening, as indicated at 30, in Figure 2, could be cut in the bench so as to provide an opening through which objects operated on could extend, but which will leave a support for the movable jaw.

It is readily apparent that a vise constructed in this way provides an open, vertical passage through which objects to be operated on will be extended, and in this way makes the work of bending pipes and rods easier. It also provides for quicker adjustment and an easier releasing or locking of the jaws.

It is apparent also that various details in the construction of the parts may be varied without departing from the spirit of the invention, and for this reason it is notintended that the invention be limited only to the details herein illustrated.

Having thus described my invention, what I claim as new therein and desire to secure by Letters-Patent, is:

A vise of the class described, comprising a casing adapted to be fixed to a bench, or the like, and having a transverse opening in its top wall, an integral jaw at one end, a jaw carrier camprising a pair of parallel rods slidably mounted in the casing and extending therefrom, a cross head secured to the outer ends of said rods and ratchet teeth formed on the inclosed ends oi? said rods, a block fitted within the casing opening having teeth adapted to oppose the teeth of said rods, a clamping lever operable to press the block 'in holding relation with the rods, a spring for lifting the block from holding relation when the lever is released, a jaw movably mounted on the outer ends of the rods and movable with the carrier toward and from the fixed jaw and an adjusting screw threaded through the cross head and connected with the movable jaw whereby it may be adjusted toward and from the fixed jaw.
