Application filed September 11, 1909. Serial No. 517,214.

To all whom 'it may concern:

Be it known that I, ROBERT J. SGHLossnn, a citizen of the United States, residing at larren, in the count-y of lVarren and State of Pennsylvania, have invented a new and useful Vise, of which the following is a specification.

This invent-ion relates to vises and one of its objects is to provide a device of this character having cooperating jaws, one of which is mounted to slide with respect to the other jaw while said last mentioned jaw is capable of swinging about an axis extending perpendicularly to the line of movement of the slidable jaw, the vise being thus especially adapted for gripping objects having opposed converging faces.

Another object is to provide improved means whereby the laterally adjustable or swinging jaw can be securely held in any position to which it may be shifted, the means utilized for this purpose being under the control of the shifting screw of the slidable jaw.

A still further object is to provide improved means for positively locking the two jaws with their working faces parallel.

A still further object is to provide a vise the jaws of which can be simultaneously shifted about the axis of the base of theV vise without disarranging any of the parts of the mechanism.

l.Vith these and other objects in view the invention consists in certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claims.

In the accompanying drawings the preferred forms of the invention have been shown.

In said drawings :-'-Figure 1 is a vertical longitudinal section through a vise embodying the present improvements. Fig. 2 is a plan view thereof, the main jaw being swung laterally out of its normal position. Fig. 3 is a section on line A-B of Fig. 1. Fig. i is a longitudinal section through a portion of a modified form of vise. Fig. 5 is a longitudinal section through a portion of another modified form of vise. Fig. 6 is a horizontal section through the vise in a plane with the longitudinal axis of the screw, said screw being shown in plan and partly broken away.

Referring to the figures by characters of reference 1 designates a preferably circular base designed to be bolted or otherwise secured to a supporting structure and this base has an upstanding tubular portion 2 at the center thereof which is surrounded by an annular shoulder 3 and has its upper end interiorly iared as at 2. A ring A bears upon the shoulder 3 and is designed to rotate around the extension 2, this ring carrying an upstanding arched portion 5 which is integral therewith and has a main jaw 6 formed thereon. A longitudinally channeled slide 7 is mounted within the arch 5 and carries a jaw 8, one end of the slide being closed as indicated at 9 and having an adjusting screw 10 swiveled therein as shown at 11, the projecting end 12 of the screw being provided with a handle 13, preferably in the form of a rod slidably mounted within the end 12 as ordinarily.

As shown particularly in Figs. 2 and 6 the yoke 5 has its side walls diverging from their centers toward their outer ends, the width of the contracted portion of the opening within the yoke being substantially equal to the width of the slide 7. It will be apparent therefore that the yoke is capable of swinging laterally with relation to the slide, so as to bring the working face of the jaw 6 to any desired angle with relation to the corresponding face of the jaw 8. The diverging faces of the yoke 5 have been indicated at 14.

A central opening 15 is formed within the base 1 and communicates with the interior of the tubular extension 2, this opening 15 being designed to receive the head 16 of a stud 17 designed to fit within the channel in the slide 7. This stud has a tapered opening 18 extending therethrough and in which a wedge 19 is slidably mounted. Said wedge has its bottom portion 20 extending into the flared portion 2 of extension 2 and provided with an inclined face 20, designed to bear on said flared portion 2, there being a screwthreaded bore 21 formed longitudinally within the wedge and in which is mounted a portion of the adjusting screw 10, heretofore referred to. A holding screw or pin 22 extends transversely into or through the stud 17 and wedge 19, so as to prevent accidental displacement of the wedge, but in order to permit a slight relative movement of the wedge within the stud, the opening 23 in said wedge and within which the pin 22 is mounted, is slightly greater than the diameter of the pin 22.

Parallel ears 211 extend vradially from the ring 4, said ears being connected at their inner and outer ends by means of cross-pieces 25 and 26, and a dog 27 is pivotally mounted between the ears and hasa laterally extending head 28 at its free end, the length of this head being substantially equal to the.

width of the channel within the slide 7, so that when the head is seated within the lower portion of the channel said slide 7 and the ring 4 are held against independent lateral movement. A spring 29 is preferably interposed between one end of the-dog 27 and the cross-piece 25, so as to hold the head 28 normally seated within the channel inthe slide 7. A fmger-piece 30 preferably extends'from the dog 27 to a point where it can be conveniently reached forthe purpose of moving the dog downwardly out of engagement with the slide.

It is to be understood that when the device is to 'be used in the ordinary manner the head 28 of the dog 27 is seated within the channel in slide 7 and the working faces of the two jaws 6 and 8 are thus maintained `parallel during all adjustments of the jaws. By turning the screw 10`in one direction the jaw S and its slide 7 can be moved .away from the jaw G, this action also resulting in the shifting of the wedge 19 so as to loosen itsgrip upon the extension 2. The frictional engagement of the head 16 with the'base 1 1s also correspondingly reduced, and it there-` fore becomes possible for the two vjaws and ltheir supports to be moved about the axis of the tubular extension 2. 'When the movement of the screw 10 is reversed the jaw 8 is shifted toward the jaw 6 and will finally clamp upon an object inserted between the jaws. As soon as this clamping action begins the screw 10 operates to draw the wedge 19 toward the closed end 9 of the channel within the slide, and said wedge therefore operates to bind upon the extension 2 .and pull upwardly to a slight extent upon the stud 17, thus causing the head 16-of the stud to clamp upon the wall of the opening 15 and hold the vise against rotation upon the base.

Should it vbe desired to clamp .the jaws upon a tapered object, the dog 27 is depressed so as to disengage the head 28 from the slide 7, and the yoke 5 can thenvbe swung laterally so as to bring the jaw 6 to any desired angle with relation to the jaw 8. The object to be clamped can then be Iplaced between the jaws, and when said jaws are tightened thereon the screw 10 will shift the wedge 19 so as to cause itto bind against the extension 2 with sufficient pressure 'to` hold the wedge and the ring et against rotation, it being obvious of course that this action of the parts will result in the head 1G of the stud 17 binding against the wall of opening l15, so as to `preventvthe stud from rotating.

As shown yin Fig. l the head of the stud is preferably frusto-conical, so as to bear against a correspondingly tapered portion of the opening 15. 1f preferred, however, said headcan be in the form of an annular flange, as indicated at 31, Fig. et. Another arrangement has been disclosed in Fig. 5, wherein a cup-like washer or disk 35 constitutes the head and has a yoke 3G pivotally connected to it and straddling the wedge 37, there beinga rounded projection within the top portion of the yoke, as indicated at 3S, which projects loosely into a recess39 formed within the top of thc wedge, there being sutilcient play between the wall of the recess 39 and the projection 38 to permit the slight movement of the wedge necessary in order' to bind upon or to release the ring during the adjustment of the parts as heretofore explained.

1n connection with the structure shown in Figs. 41, 2 and 3, it might be further `explained that while that portion of the stud 17 which is located within the slide 7 is substantially rectangular, that .portion of the stud located within the tubular extension 2 is cylindrical. This is, of course, necessary in order to permit the stud to rotate during the swinging movement ofthe vise jaws about the axis of the extension 2.

It is, of course, to be understood that vari` ous changes may be made in the construction and arrangement of the parts ywithout departing from the spirit or sacrificing the advantagesfof the invention.
