IINITEU @TATEfi PATENT @IIFIQE GEORGE AMBORN, OF OHAPINVILLE, CONNECTICUT, ASSIGNOR TO J. H. WILLIAMS 8: (30., OF BROOKLYN, NEN YORK, A CGRPQRA'IION OF NEW YORK.
CHAIN PIIF'E-VISE OR THE LIKE.
To all whom it may concern Be it known that I, GEORGE AMBoRN, a citizen of the United States, residing in Chapinville, in the county of Litchfield and State of Connecticut, have invented certain new and useful Improvements in Chain Pipe-Vises or the Like, of which the following is a specification.
This invention relates to chain pipe vises or the like, and aims to provide certain improvements therein.
Chain pipe vises as commonly constructed usually comprise a pair of jaws having working faces upon which the pipe rests, a chain adapted to pass around the pipe and having one end connected with a screw or other take-up mechanism, the other end of the chain being adapted to be locked in varying positions to the bed-plate of the device. In such constructions the chain is tightened by a movement of the end which is connected to the take-up device, the chain slipping around the pipe until the desired tension is reached.
According to the present invention I provide a construction in which the take-up device operates against both ends of the chain so that the pipe is pressed upon the jaws uniformly without any substantial twisting movement. In this construction also the chain may be tightened more quickly than heretofore because of the fact that it is in effect shortened at both ends.
My invention also provides means whereby the tension on the chain may be equalized.
The invention is specifically directed to an adjusting member which is located beneath the bed-plate of the vise.
Referring to the drawings, which illustrate one form of the invention, Figure 1 is an end elevation, and Fig. 2 a front elevation.
Referring to the drawings, let A indicate a suitable bed-plate upon which are mounted a jaw or jaws B B. These jaws may be of any suitable construction and are provided with the usual working faces C designed to support the pipe. The chain D is adapted to pass around the pipe and clamp it upon the jaws as heretofore.
According to the present invention means are provided for in effect tightening both ends of the chain, whereby the pipe is clamped firmly against the jaws without In the Specification of Letters Patent.

Serial No. 668,062.
construction illustrated this result is accomplished by a cross-piece L which is located below the bedplate A, and is fixedly secured to the front end of the chain in any suitable manner, as by the pin shown. The opposite end of the cross-piece or yoke L is formed with or carries a lock or locks F F designed to engage the free end of the chain. Any suitable means may be provided for adjusting the cross-piece L to tighten the chain, but I prefer that shown which comprises a screw-threaded bolt M passing through a suitable screw-threaded bore in the cross-piece, and engaging the bed-plate A. The upper end of the bolt M is preferably rounded to form a head N which enters a rounded socket 0 formed in the bed-plate, the bolt being retained in position by pins Q Q, engaging a neck P formed beneath the head N. By this means the screw M is adapted to move so that the cross-piece L may tilt slightly to equalize the strains on both ends of the chain.
While I have shown and described in detail one form of the invention it is to be understood that various changes may be made therein without departing from the spirit of the invention. The cross-piece or yoke L may be variously constructed and for the screw M may be substituted any suitable form of device for moving the crosspiece.
I do not in this application broadly claim a construction in which means are provided for tightening both ends of the chain, or the use of a cross-piece per cc, these being the subject of my application No. 668,061
filed of even date herewith.
What I claim is 1. In a chain pipe vise or the like, the combination of a jaw, a fixed bed plate upon which said aw is carried, a chain fastened at one of its ends and having a free end adapted to be passed over a pipe and fastened adjustably at determined intervals in its length so as to embrace pipes of different diameters, and means for thereafter effecting a relative tightening movement between the jaw and both ends of the chain, said means being located below the bed late. p 2. In a chain pipe vise or the like, the combination of a jaw, a fixed bed plate upon which said jaw is carried, a chain fastened at one of its ends and having a free end adapted to be passed over a pipe and fastened adjustably at determined intervals in its length so as to embrace pipes of different diameters, a member located below the bed plate adapted to be engaged by both ends of the chain, and means for moving said member to move both ends of the chain in a tightening direction.
3. In a chain pipe Vise or the like, the
combination of a jaw, a fixed bed plate upon which said jaw is carried, a chain fastened at one of its ends and having a free end adapted to be passed over a pipe and fastened adjustably at determined intervals in its length so as to embrace pipes of different diameters, a cross-piece located below the bedplate and adapted to be connected to both ends of the chain, and means for moving said cross-piece and thereby moving both ends of the chain simultaneously in the same direction.
4. A chain pipe vise including in combination a jaw, a fixed bed plate upon which said jaw is carried, a chain and a cross-piece located below the bed plate and connected to one end of the chain, said cross-piece having a lock adapted to engage the other end of a chain, and means for moving said cross-piece.
5. A chain pipe vise including in combination a jaw, a fixed bed plate, a chain, means for eiiecting a relative movement between the jaw and both ends of the chain, and means for equalizing the strain on the two ends of the chain.
6. A chain pipe vise including in combination a jaw, a fixed bed plate, a chain, a member adapted to be connected to both ends of the chain, and means for permitting a tilting movement of said member.
7 A chain pipe vise including in combination a jaw, a fixed bed plate upon which said jaw is carried, a chain, means for effecting a relative movement between the jaw and both ends of the chain, said means being located below the bed plate, and a lock on said means.
8. A chain pipe vise including in combination a jaw, a fixed bed plate, a chain, means for effecting a relative movement between the jaw and both ends of the chain, said means being located below the jaws, and means for equalizing the strain on the two ends of the chain.
9. A chain pipe vise including in combination a jaw, a fixed bed plate, a chain, a member located below the jaw and adapted to be connected to both ends of the chain, and a screw passing through said member, said screw being adapted to be tilted to equalize the strain on the two ends of the chain.
10. A chain pipe vise including in com bination a jaw, a fixed bed plate, a chain, a cross-piece adapted to be connected to both ends of the chain, and a screw passing through said cross-piece and having a rounded end whereby the screw may be moved to tilt the cross-piece.
11. In a chain pipe vise or the like, the combination of a pair of jaws, a chain passing between said jaws, a cross-piece located below the jaws and connected to said chain at one end, a lock formed on the opposite end of said cross-piece, and a screw passing through said cross-piece, said screw being movably mounted whereby said cross-piece may tilt to equalize the strain on the chain.
In witness whereof, I have hereunto signed my name in the presence of two subscribing witnesses.
