SPEGIFIGATION forming part of Letters Patent N 0. 732,760, dated July 7, 1903.

Application filed October 17, 1902. Serial No. 127,625. (No model.)

To all whom it may concern.-

Be it known that 1, JOHN R. LONG, a citizen of the United States, residing at Akron, in the county of Summit and State of Ohio, have invented certain new and useful Improvements in Pipe-Vises; and I do declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to pipe-Vises and the invention consists in certain improvements upon thevises describedand claimed in my two concurrent applications serially numbered,respectively, 127,623 and 127,624. In the first of said applications I describe and claim more particularly a pipe-vise having a single rotatable element or member constructed to prevent rectilinear movement in its support and provided with means to engage a pipe and lock said member against rotation. In the second application the same general features appear as in the first, with the addedfeature of a second rotatable member, so that thereby practically the equivalent of a universaljoint rotation is obtained for the jaw of the vise.

In the present application the invention is an improvement more particularly upon the second of the above applications, wherein there is shown a practically divided base, the division running down to the'base-support, but leaving the base integral below that point. The present construction has a base divided into two equal parts or sections and is constructed and adapted to operate substantially as shown and described, and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a plan side elevation of my improved vise, showing a section of pipe'clamped therein. Fig. 2 is a plan view thereof. Fig. 3 is a hori-' zontal central sectional plan view of therear part of the vise. Fig. at is a vertical sectional elevation of the-vise lengthwise thereof. Fig. 5 is a perspective view of the jaw or jaw member alone. Figs. 6 and 7 are details, respectively, of the locking-nut and its handle and of one of the base sections or members. Fig. 8, Sheet 1, is a sectional elevation of a modification of the vise.

As thus shown, A represents the vise-support,-having an annular seat or flange a, which is adapted to receive the hub of base B. The

movement for frictionally locking them in the said flange a. This will appear more fully in the description farther along. The flat meeting surfaces of the hub-sections in the base terminate at a, from which point the two sides or sections of the base are shown as diverging somewhat, but not necessarily as much as shown, and the upper portion of each section of the base is constructed with a tubular bearing 2, adapted to receive the barrel or bodyc of the jaw or jaw member O. Said body 0 rests in both said bearings and is provided with a shoulder a to prevent lengthwise movement therein to the rear. The said jaw is therefore axially rotatable in its bearing and has a solid head, upon the sides of which are atfixed the steel jaws tially V-shaped serrated edges d, adapted to engage pipe P when the same is bound there upon by chain E. Said chain is attached at one end to the screw Gand is free at its other end to be engagedupon the two lugs 3 on head 0 which have inclined slots 4 on their inner sides and inclined rear edges parallel to these slots adapted to be engaged by the laterally-projecting pins 5, which connect the double links of the chain. In this way two sets of said pins are brought into engagement at the same time with said lugs and make a very strong hold for the chain. V p

The chain enters the hollow interior of the body of the jaw through an opening back of head 0 and the screw G' is supported 'upon the rear end of the body or barrel 0 of the jaw by means of a cap H, having suitable screws h. It will be noticed that there is a slight space left beneath the heads of these screws in cap H to give the said cap suflicient to-and-fro movement to adapt it to the clamping of the parts when the nut J is tightened. The screw Gis free to slide in cap H, and

hence is not threaded therein, and the cap is deep enough to give the screw the requisite bearing to hold it up relatively as shown, and when the jaw is rotated the chain and the screw will necessarily rotate therewith. Assuming now that the chain is drawn closely about the pipe and nut J is tightened, the jaw is locked against rotation and the basesections are drawn toward each other at the top and spread at the bottom into frictional locking engagement in flange A by the tightening of the nut against cap H. In this way the clamping mechanism is made to lock both the base and the jaw on their respective rotatable surfaces, and the entire structure becomes, as it were, one rigid piece when the clamping is thus effectually done. Any suit able handle L for turning nut J may be used.

In Fig. 8 I show a modification in which a fulcrum-ring is engaged about barrel 0 of the jaw and is adapted to rest down between the opposite sides 8 of recess in the base in the upper portion of its hub relatively as shown, and one-half of said recess comes in each section of the hub. Said ringis supported upon said barrel or body O to rotate therewith, and it follows when the clamping of the vise occurs that the engaging portion of the ring within the surfaces 8 constitutes a fulcrum against which the sections of the base bear and spread laterally below to lock in the flange a, while they yield slightly toward each other on the top. Of course it is understood that all these parts fit quite snugly together, so that there really is no visible movement when clamping occurs, but still enough for all looking purposes.

What I claim is- 1. In pipe-Vises, a suitable support, a base in two separate sections rotatably seated on said support, a jaw rotatable in the upper portions of said sections, and clamping mechanism for said jaw and said sections, whereby both are locked at the same time, substantially as described.

2. A vise-support having an annular seat and a base with a hub resting insaid seat, said hub split centrally in two parts and said parts having substantially flat meeting surfaces, in combination with a jaw having a tubular body rotatably supported in the upper portion of the said base, and means to lock said jaw and the base against rotation, substantially as described.

3. A pipe-vise comprising a support having a flanged seat, a two-part base rotatably resting in said seat and provided with tubular hearings in their top portion, a jaw having a body engaged in said bearings and mechanism to lock said parts rigidly together comprising a screw in the jaw, a chain connected with the inner end thereof and with the jaw, and means bearing against the outer sides of the base, substantially as described.

4. The support for the vise having an annular seat, a sectional base having a hub divided at its middle between said sections and resting in said seat, said sections each having an annular hearing at its top at right angles to its hub portion, in combination with a jaw provided with a hollow body rotatable in said bearings and having a shoulder to prevent endwise movement therein, a screw and a chain engaged with one end thereof in the jaw and removably fixed to the jaw at its other end, a cap supporting the screw in the jaw and a nut on the screw bearing against said cap, substantially as described.

5. In a pipe-vise, a base consisting of two sections having each half of a complete cylindrical hub at its lower end and a tubular bearing in its top, the meeting surfaces of the said hub portions being flat and the said sections spaced apart above said meeting surfaces, and a support having a circular seat in which said hub rests, in combination with a jaw rotatably supported in said rest, and having a shoulder bearing against one section thereof, and a cap on the other end of said jaw bearing against the other section, and means to clamp said cap and shoulder against said sections, whereby the said sections are locked in the base-support and the jaw is held against rotation, substantially as described.

Witness my hand to the foregoing specification this 6th day of October, 1902.
