' VISE.

Specification of Letters Patent. Patented N 13,'1917 Application filed Janiiary 14, 1913. I Serial No. 742,007.

To all whom it may. concern:

Be it known that we, THEODORE H. Dnssnz and Gos'ravn It. 'THoMrsoN', both of New York city, New York, haveinvented certain new and useful Improvements in Vises, of which thefollowing is a specification.

The invention relates to vises orthe like, and especially to pipe-Vises or clamps, and aims to provide improvements therein.

Means are provided by the invention whereby objects and more especially pipes or other rounded objects, may be quickly and readily gripped'and held, the means being adapted to operate with rapidity to adjust itself to and to grip and securely hold the object to be held. The meansare further more of extreme simplicity and may be very cheaply manufactured. Other features of improvement will be set forth hereinafter.

Two embodiments of the invention are illustrated in the accompanying drawing, wherein Figure l is a side elevation, with parts in' section, of a vise embodying the invention.

Fig. 2 is a front view of the construction shown in Fig. 1.

Fig. 3 is a detail View of one of the parts.

Fig. 4 is a side view of a part of a vise showing another embodiment of the 1nvention.

Fig. 5 is a front elevation of the part shown in Fig. 4.

In said drawings, the letter A designates a bar or standard having a jaw B thereon, and the letter C designates a socket-piece having a socket D therein for the standard, and having a jaw E, the two jaws being adapted to grip between them articles which are to be held by the vise.

The socket-piece and standard or bar are adapted to move freely upon one another in order to bring the jaws together upon an object to be clamped, and are adapted to be held in clamping position by a suitable cam F. The cam is preferably adapted to bear directly upon the bar or standard A and preferably turns in a direction to force the jaws on the standard and socket-piece together upon an object to be held between the jaws. Either the cam or the standard may be roughened in order that the cam may exert a greater force in drawing the jaws of the vise together. In the drawing the cam is shown as roughened at G.

The inner rear face H of the socket-piece jaw will move little, if any, line,

as the movement around the edge K is on a long radius and at substantiallyright angles to the direction of movement of the parts. a r

The standard is preferably arranged so as to stand vertically andthe socket-piece is preferably adapted to move on the standard, oneof the parts, as in the present instance the standard, being, provided with suitable means, such as bolt-holes L, by

which the vise maybe secured toa support. The socket-piece being movable in a vertical plane, may move under the force of gravity, when not held by the cam, to bringthe aws together on the article tobe gripped. The socket-piece may therefore be raised and dropped, and be thereby brought readily and quickly into position to grip articles between the jaws of the vise. After the jaws are in position, a simple pull upon the handle of the cam will force the jaws together upon the object between them and securely fasten the socket-piece to the standard and hold the jaws in clamping position.

By weighting the end of the handle attached to the cam, as indicated at U the cam may be caused to operate automatically to force the jaws together and to bind the socket-piece upon the standard.

As shown in Figs. 1, 2 and 3, the cam is provided with trunnions M, M. The trunnions M, M, are slightly larger than the cam, shoulders I N, being formed between the cam and trunnions. The hole O in the socket-piece within which the cam and trun nions fit is bored so as to bring the shoulders N, N, between the cam and trunnions, behind the sides of the standard when the socket-piece is in place thereon, and thereby lock the cam against lateral displacement in its bearings.

In Figs. l and 5, the cam is shown as pivoted upon a pivotpin S between two side plates T, T, formed on the socket-piece. In this construction the cam and its pivot pin may be made in separate parts, for economy in manufacture.

The invention has been shown as embodied in a pipe vise. For this purpose the out of a straight jaws are provided with angular gripping faces P, P, provided with teeth Q, Q, and the jaws may be arranged to overlap, as indicated in Fig. 2, so as to adapt the vise to operate upon a greater range of diameters of pipe.

By the present invention the vise may be made of a very few simple parts, and can be operated very expeditiously. The tightening of the jaws on the object to be gripped and the fastening of the jaws in binding engagement may be quickly done at one very simple manual operation. This operation may, in fact, even take place automatically.

The inventive ideas herein set forth may be embodied in other constructions than those herein illustrated and described. They are capable of receiving a variety of mechanical expressions.

WVhat is claimed is:

1. A vise or the like comprising a base provided with agripping jaw and an upright bar having a plain surface; a complemental jaw movably mounted on said bar, and a cam journaled on the movable jaw and rotatable into and out of engagement with said plain surface on an axis parallel thereto, to force said jaw into gripping relation both with the said bar and the work held between the jaws.

2, A vise or the like comprising a standard or bar and a socket-piece having jaws thereon, said socket-piece and bar being relatively movable to bring said jaws together on an article to be gripped, and a cam adapted to fasten said socket-piece and which said jaw is adapted to rock toward said first-named jaw, said jaw having an inclined face H permitting said rocking movement, and a cam on said jaw diagonally opposite said bearing edge K, adapted to rock said jaw and lock it in gripping position.

In testimony whereof we have hereunto signed our names in the presence of two subscribing witnesses.
