WILLIAM ANDREW KYLE, OF BUFFALO, NEW YORK, ASSIGNOR TO PETER E. MACDONALD, 0F TORONTO, CANADA.

VISE.

Specification of Letters Patent.

Patented Nov. 28, 1911.

To all whom it may concern:

Be it known that I, VViLLIA M ANDREW HYLE, a citizen of the United States, and resident of Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Vises, of which the following is a specification.

This invention relates to a vise which is used more particularly for holding pipes but which may also be used for other purposes.

One of the objects of this invention is the provision of simple and efficient means whereby the principal part of the adjustment of the vise may be effected quickly and only the final tightening effected slowly.

This invention has the further object to render the movement of the parts while opening and closing the vise easy and to so construct the parts that the vise is very strong, that worn parts can be realily replaced and the vise can be produced at low cost.

In the accompanying drawings consisting of 2 sheets: Figure 1 is a horizontal section in line 11, Fig. 2. Fig. 2 is an end elevation of the vise. Fig. 3 is a vertical longitudinal section in line 33, Fig. 1. Figs. 4, 5 and 6 are vertical transverse sections in the correspondingly numbered lines in Fig. 8.

Similar letters of reference indicate corresponding parts throughout the several views.

A represents the base of the vise which may be secured to a work bench or other support in any suitable manner. At its front and rear ends this base is provided with two upright front and rear standards or posts B, C which are fixed on the base and preferably cast integrally therewith. Between the two standards the base is provided with a longitudinal slot D which is undercut so as to form downwardly facing shoulders 03, d on opposite sides of the slot, as shown in Figs. 3, 4 and 6. To the rear standard are secured the two widely separated sections E, E of a rear fixed gripping jaw which are adapted to engage with the rear side of the pipe and widely separated points and which are detachably secured to opposite sides of the rear standard by bolts 6, as shown, or by any other suitable means. Arranged in front of the space between the rear fixed. jaw sections are two narrowly spaced sections F, F of a front movable gripping jaw which are adapted to bear against the front side of the pipe at two points arranged comparatively close together and out of line with the bearing points of the rear jaw sections. It will thus be noted that the pipe by this means is gripped at four different places whereby the same is positively held against turning while a thread is being cut on the same or other work is being performed thereon which requires the pipe to be held firmly.

The front jaw sections are secured by bolts 9 or otherwise to opposite sides of an upright longitudinally movable slide G which projects at its lower end downwardly through the guide slot D and moves lengthwise therein for opening and closing the vise. The lower ends of the front jaw sections are arranged above the base on opposite sides of the slot D and thereby prevent downward movement of the front jaw and slide. Upward movement of these parts is prevented by a cross head it arranged at the lower end of the slide G and engaging at its opposite ends with the shoulders 03, a? of the slot D.

In order to cause the front aw and slide to move freely without liability of becoming cramped or bound, rolling members or bearings are interposed between the lower ends of the front aw sections and the base. These rolling members preferably consist of a plurality of balls 2' arranged in recesses 71 in the lower ends of the front jaw-sections and engaging with longitudinal rim ways on the upper side of the base on opposite sides of the slot D, as shown in Figs. 2 and 6.

The forward and backward movement of the front jaw and slide relatively to the rear jaw may be effected by various means but preferably a horizontal screw J which is operatively connected at its front end with the front jaw and slide and works in a screw nut in the front standard. The preferred means for connecting the screw with the slide and front jaw comprises a spherical knuckle L connected with the rear end of the screw by a contracted neck Z and seated in a spherical socket in the slide and front jaw sections. As shown, this socket is formed by means of a notch arranged in the front edge of the slide and consisting of a narrow or contracted outer part m and an enlarged inner part m and two concave recesses 12, formed on the inner sides of the front jaw sections in line with the enlarged inner part m of said notch.

In the assembled condition of the parts the neck Z of the screw is arranged in the contracted part m of the notch and the spherical knuckle engages centrally between its laterally opposite sides with the enlarged part m of the notch while its opposite sides engage with the recesses n of the-front jaw sections, thereby forming a swiveling connection between the screw and movable jaws which permits of freely adjusting the latter without liability of binding and still keeping the cost of manufacture and the capacity of being repaired within practical bounds.

At its front end the screw is provided with a handle 0 for turning the same which handle may be of any suitable construction, the same being shown in the drawings,for example, in the form of a cross bar.

In its preferred form the adjusting screw nut which cooperates with the screw, as shown in Figs. 1 2, 3 and 5, is constructed of two cylindrical sections p, p which are arranged in a cylindrical socket P in the front standard and which have their opposing ends constructed to form an opening which is internally threaded and in line with openings 9, q in the front standard on opposite sides of the screw nut. The adjusting screw passes through the adjusting nut and the adjacent openings 9 of the front standard. Upon turning the screw in one direction or the other while the nut sections are both engaged therewith the front jaw will be slowly moved toward or from the rear jaw accordingly. W'hen it is desired to move the front jaw quickly toward or from the rear jaw the sections of the adjusting nut are separated and the adjusting screw is disengaged therefrom, thereby permitting the adjusting screw to be moved lengthwise through the adjusting nut without turning the same and thus enabling the main part of the adjustment of the vise to be effected rapidly. After the parts have been shifted approximately into the position for gripping a pipe the sections of the adjusting nut and the adjusting screw are again engaged and the final tightening of the jaws against the pipe is eflected by turning the adjusting screw in the screw nut. By this means the operation of adjusting the vise pipes is materially facilitated and cost of doing the work reduced accordingly.

The lower adjusting screw nut section 79 is preferably secured in the front standard by a transverse pin 1- and the upper section p is movable vertically toward and from the lower section but is held against turning.

by means of a pin 8 projecting laterally from the upper nut section through a vertical slot 8 in one side of the front standard. At its upper end the upper nut section is provided with a handle or knob s for manipulating the same.

Various means may be employed for holding the upper section p in its operative or inoperative position, the means for this purpose shown in the drawings consisting of a leaf-shaped locking spring T secured at one end to the outer side of the front standard and provided at its other end with two openings 2 t which are adapted to receive the pin s of the upper nut section. When the upper nut section is depressed into its operative position the pin 8 engages with the lower opening I? of the locking spring T, thereby holding the adjusting screw nut sections and screw in engagement with each other. Upon raising the upper screw nut section and engaging its pin .9 with the upper opening t of the locking spring this nut section will be held in its inoperative position.

By splitting the screw nut the same may be separated and the adjusting screw detached. therefrom and the movable jaw quickly shifted while the fine adjustment and tightening of the jaws is effected when the adjusting screw is engaged by the screw nut sections. The adjusting screw can be readily lifted out of engagement from the lower fixed section of the screw nut owing to the pivotal connection between this screw and the slide which carries the movable jaw.

The screw nut sections p, p are con structed from a cylindrical block which is first bored transversely, then internally threaded in this bore and then divided transversely through this bore. The opening or socket P in the standard B is of the same diameter as the screw nut sections p, p so thatthe latter fit snugly in this socket. This manner of constructing the screw nut sections and mounting the same in the standard B is very simple, reliable and eflicient and can be produced at low cost.
