JULIUS J. COWELL, OF WVEEDSPORT, NEW YORK.

VISE.

SPECIFICATION forming part of Letters Patent No. 488,600, dated December 27, 1892.

Application filed July 15, 1892. Serial No. 440.132. (No model.)

To all whom it may concern.-

Be it known that I, J ULIUS J. CowELL, of Weedsport, in the county of Cayuga, in the State of New York, have invented new and useful Improvements in Vises, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to Vises, and particularly to that-class which are quick acting,

and in which the jaws are parallel, or can be shifted to receive a tapered piece; in which a half nut and half screw are used for quick adjustment of the jaws, and which are provided with auxiliary detachable jaws for gripping round or half round bars or pipes.

My object is to produce an universal vise, with parallel jaws adapted to be shifted out of parallelism, and with auxiliary jaws for holding pipe or rounded bars, and of quick adjustment as to the jaws on account of having a half nut and a half screw, said screw, or said screw and nut, being provided with a beveled entrance for the thread of one into that of the other; and also having a spring catch for holding the screw out of engagement with the nut.

My invention consists in the several novel features of construction and operation hereinafter described and which are specifically set forth in the claims hereunto annexed. It is constructed as follows reference being had to the accompanying drawings in which Figure 1, is a side elevation of the vise complete, with the pipe jaws in position. Fig. 2, is a vertical longitudinal section, omitting the pipe jaws. Fig. 3, is asectional elevation on line :20 0c omitting the pipe jaws (Fig. 1.) Fig. 4, is a like view on line y y,Fig. 1. Fig. 5, is a top plan of the half nut. Fig. 6, is an end elevation thereof. Fig. 7, is an elevation of part of the screw enlarged. Fig. 8, is a sectional elevation of part of the screw, the adjusting collar and screw, and the slide carrying the outer jaw. Fig. 9, is a top plan of the body of thevise with the rear jaw removed, showing the semi-circular locking mortise to receive the like shaped tenon upon the base of said jaw.

A, is the body of the vise, provided with a flange 1, around its lower end, which fits onto -abase block 2, provided withcountersinks 3,

receiving the point of thestop pin 4,provided with aspring 6, whereby the body is swiveled upon the base, and can. be set at any point and held there by said pin. This body is provided with the usual horizontal mortise to receive theslide 7, which carries the front jaw 8. It is. also provided with a vertical mortise opening upward into the slide mor- 6o tise, and which receives the shank a of thehalf nut 9. 1 In the top it is also provided with amortise 10, of the shape of two semi-circles of unequal radii, adapted to receive the'post 11, and flange 12, upon the bottom of therear jaw 13, so that the flange can be turned under the over hang of the mortise. The rear face of this jaw body is provided with a central countersink to receive the point of thescrew 14, by which it is held in parallelism with the outer jaw, when that is set upon the center; and has also a series of lateral concavities or countersinks like unto and on each side of the one shown in Fig. 2 adapted to also receive said screw, and said jaw is held 7 5 in any position thereby, as for taper work. And when the rear jaw is so shifted, the front one is shifted to the like or necessary degree of taper by means of the swivel mounting upon thebase block 2.

B, is the half screw, with a square out thread, of ordinary construction except that the ends of the risers of the thread are beveled or scarfed off; and the threads of the half nut are also beveled off in like manner, 8 so that in no case can two ends of threads abut against each other, and quick and sure entrance is provided for the screw threads into those of the nut, and closer jaw adjustment is permitted before the threads are brought into engagement. When the threads are out of engagement the front jaw and slide are free to move forward and back.

In the rear of the slide through which the screw passes, is ashoulder 15, and 16, is a 5 collar upon the screw, slotted longitudinally for adjustment and abutting against said shoulder, and secured in position by the screw 17, through said slot, whereby all wear upon the screw can be taken up. The front end of the screw is provided "with a handle 18, through a head which abuts'against the front end of the slide. Aspring rod 19, is secured in the slide and extends outward to engage with anotch 20, in the screw head (Fig. 4) and is adapted to play vertically in theslot 21, and to hold the screw in place when it is out of engagement with said nut.

Each jaw below its working face is provided with asocket 22, adapted to receive thestems 23, of the sections of thepipe jaws 24 and 25, which are tubular and of unequal size so that one'can slide into the other, so that a pipe or rod of any size can be gripped in the notches 26.

What I claim as my invention and desire to secure by Letters Patent is:

1. In a vise the combination with the jaws, of a slide carrying one jaw, and passing through a mortise in the rear jaw, a square threaded half screw within the slide, having the ends of its threads beveled off,anda half nut provided with a shank fitting in a mortise in the body of the rear jaw, and having the ends of its threads beveled off.

2. In a vise the combination with thejaws, of a slide carrying one jaw and passing through a mortise in the rear jaw, a square threaded half screw within the slide, and having the ends of its threads beveled off, a

half nut provided with a shank fitting in a mortise in the body of the rear jaw, and having the ends of its threads beveled off, and having a spring secured in the slide and adapted to engage with a groove in said screw and hold it out of engagement with said nut.

3. The combination with the rear jaw swiveled upon a body, and a pin adapted to engage with it, said body beingadjustably swivel'ed upon a base, and a front jaw mounted upon a slide passing through a mortise in said body, a half screw through said slide,

and a half nut mounted in a mortise within JULIUS J. OOWELL. In presence of HERBERT A. (JARHART, HOWARD P. DENISON.
