SPECIFICATION forming' part of Letters Patent No. 542,244, dated July 9, 1895.

Application iiled September 1l, 1894. Serial No. 522,708. (No model.)

To all whom it may concern,.-

Be it known that I, CLARE ERNST, acitizen of the United States,'residing at Bay City, in the county of Bay and State of Michigan, have invented certain new and useful Improvements in Vises, of which the following is a specication, reference being'had therein to the accompanying drawings. l

The invention consists in the construction of a vise of that type in which the nut in the stationary jaw is separable to be disengaged from the screw to permit of the quick adj ustment of the jaws to or from each other; and the invention consists particularly in the peculiar construction of the actuating devices for such nut-sections; further, in the peculiar construction of the swivel-support for the vise, and, further, inthe peculiar construction of the swivel-support for the movable jaw, and in the construction, arrangement, and combination of the various parts, all as more fully hereinafter described, and shown in the accompanying drawings.

Figure l is a vertical central longitudinal section througha vise embodying my invention. Fig. 2 is a top plan view thereof, showing the movable jaw secured at an angle to the stationary jaw. Fig. 3 is a perspective View of the movable j aw and the swivel clamping plate or nut. Fig.' 4 is a horizontal section on line x os, Fig. l. Fig. 5 is a vertical section on line y y, Fig. l. Fig. 6 is an elevation of the lower nut-section, showing the operating-lever and in dotted lines the position of the upper nut-section when the sections are separated. Fig. 7 is a perspective View of the bed-plate and the swivel-post of the stationary jaw, showing the manner of detachably and adj ustably engaging that jaw in the plate.

A is the stationary jaw, and B the movable jaw, of a vise. The stationary jaw has a transverse guideway, in which is slidingly secured the tubular arm C of the movable jaw.

D is a tubular post on the lower side of the stationary jaw, having the ange D', which rests upon the bed-plate D3, which may be secured to the usual bench, the post being swiveled upon this flange in a central tubular aperture in the bed-plate.

'The bed-plate is provided with engaging notches a and the post is provided with lugs b, adapted to enter these notches and to lock the post (and vise) to the bed-plate by a partial rotation in the manner plainly illust-rated in Figs. 1 and 7.

VAround the edge of the bed-plate in its upper face is formed the T-shaped slot c, in which the heads of clamping-bolts d engage. These bolts passthroughthe flange D and are provided with suitable clamping-nuts e above the flange, by means of which construction the vise may be held at any desired angle to the bench or bed-plate.

YThe forward end of the arm C is provided at its lower edge with the forwardly-extending plate E, upon which rests the jaw B. The jaw is provided with a semicyliudrical boss E', engaging a grooved or curved bearing E2 on the forward face of the arm C. The forward face of the plate F is of segmental circular configuration, and H is a depending lip for the jaw, having its inner face of corresponding shape to fit the face of the plate and about which it is adapted to turn.

I is a clamping screw or bolt engaging a screw-threaded bearing in the plate, passing through a segmental slot in the lip and through an aperture in the curved clamping plate or nut J, which bears against the outer face of the jaw B, which is correspondingly curved.

K is a fan-shaped aperture through theV jaw B, through which the screw J passes, passing, also, through an aperture through the plate J and swiveled in the rear end of the arm C, as plainly illustrated in Fig. l.

It willvbe evident from the description of the parts last described that by loosening the bolt I the jaw B may be turned at any desired angle to the stationary jaw-as, for instance, as shown in Fig. 2-and then clamped in its adjusted position by tightening the bolt I.

M is a lip on the jaw B, engaging over the top o`f the arm C to prevent dust, dirt, or shavings from entering the swivel-joint on which the jaw B turns.

N is the upper section of the nut, having the leg N', and O is the lower nut-section,'

having the leg O, these legs depending into the post, separated from each other a sufti- IOO cient distance to permit of the actuating-lever P being arranged and operating between. This lever has a cam-head Q and a weighted offset Q at its lowei1 end. It is pivoted on the pin 7L in the leg N of the upper nut-seetion and its cam-head is located between two opposite cam-lugs 'i t" on the inner face of the leg of the lower nut-section.

II is a stop-pin located a short distance below the lowerend of the leg of the lower nutsection in the closed position of the parts. (Shown in Fig. l.)

R is a cord connected to the outer end of the cam-head, by means ot' which the lever and cam may be rocked about its pivot to open and close the nut-sections in the following manner: The parts being as shown in Fig. l, the weight Q willact to hold the cam head directly beneath the cam-lug t' and lock the two nut-sections tightly upon the screw. Vtlhen the operator. draws upon the cord R, he rocks the lever about its pivotal point z, withtflrawing the cam from beneath the lng fi, and at the same time the under face of the cam-head strikes the lng t" and forces the lower nut-section down until it strikes the stop-pin 7s, when further movement of the lever will cause the lever to fulerum on the lug e" and lift its pivotal point, thereby raising the upper nut-section tree from the screw, thus permitting the screw to be shi l'ted horizontally without engagement of the screw in the nut.

It is evident that when the nut engages the screw by turning the screw the movable jaw will be caused to approach or recede from thc stationary jaw in the usual manner ot operating vises.

Thus it will be seen that this vise comprises a separable screw-nnt with means of opening it to admit of quick adjustment of the movable jaw, a swiveled movable jaw, and a swiveled post for supporting the entire vise.

What I claim as my invention is l. In a vise, the combination of a bed-plate, a post swiveled thereon, a stationary jaw on the post, a horizontal arm slidingly engaging in a transverse aperture in the stationary jaw, the movable jaw swiveled on the end of said arm, and the set screw passing through the arm and swivcled jaw snbstantiall r as described.

2. In a vise, the combination ot a bed-plate, a post swiveled thereon, a flange on the post resting on the plate, lugs on the post adapted to enter notches in the plate and to be locked beneath the same by a partial rotation, and bolts on the post, entering undercut grooves in the plate, to lock the post in its adjusted position, substantially as described.

In a' vise, the combination of the stationary jaw, having a transverse aperture, an arm sliding therein, a screw in the arm, the plate E at; the forward end of the arm, the movable jaw supported on the plate and having a swivel joint connection with the forward end of the arm, a clamping bolt on the arm passing through a segmental slot in the jaw, and a clamping plate or nut on the outer face ot the jaw, with which said bolt engages, and in which the screw is journaled substantially as described.

4. In a vise, the combination of the stationary jaw having a transverse aperture, an arm sliding therein, the plate E at the forward end of the arm, the movable jaw supported on this plate, a fan shaped slot through the jaw the screw in the arm, passing through the fan shaped slot in the movable jaw, a clamping plate or uut supporting the outer end of the screw, and securing devices for clamping the jaw between the arm C and the clamping plate in its adjusted position, substantially as described.

5. Ina vise, the combination ofthe tubular post carrying the stationary and movable jaws, the screw therethrough, the upper and lower nut sections engaging the screw, the separated legs on the nut sections depending into the post, the lugs t '11 on the leg of the lower section. the lever pivoted to the inside of the leg ot the upper section between the lugs, and the cam head on thelever, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

CLARE EtNST.
