VISE

Filed Aug. 29, 1930 Ha I INVENTOR Patented Dec. 6, 1932 UNITED STATES,

PATENT FFICE EDWIN W. FULTON, F OSWEGO, NEW YORK VISE The device, the subject of this invention, is a vise, and the special objects of the invention are to provide a vise that has not only a plurality of improvements, but a plurality of uses.

Up until a short time ago, vises merely consisted of jaws of work holding means, adapted to be closed together, and to hold an object between them. As the faces of the jaws were usually arranged parallel, it was quite obvious that round bodies, such as pipes, cylinders or disks could not be held between such jaws.

The next improvement was the addition of pipe jaws, as an auxiliary to the fiat, or machinist jaws, and while such plpe jaws serve to hold pipes or cylinders in one position, still there was something lacking to make a vise complete and eflicient.

In this invention, I have provided an additional pair of jaws or work holding means designed for the purpose of holding disks or cylinders, and therefore the vise which I have shown, and which I will describe, has three i distinct pairs of jaws, all operated from a single source, and so proportioned that the effect of closing of any pair of jaws will not be in any way hampered by the premature closing of any other pair of jaws.

Another object of this invention is to provide means for retaining the screw or worm which causes the operation of the movable jaw members, and I have included other improvements which will be fully described in the specification which follows.

The following is what I consider the best means of carrying out my invention, and the accompanying drawing should be referred to for a complete understanding of the specification which follows.

- My vise is constructed with a vise member 1 and a plate adapted to swivel thereon. The plate 2 is held in an adjusted position by the capped bolt 3, which passes through a screw threaded perforation in the plate 2, and enters a recess in the base member 1. The wrench i irremovable from the bolt .3, serves as a means for turning the bolt.

Formed integral with the plate 2, is the body portion of my vise, which consists of a cylinder 4, having formed therewith, the stationary jaw member.

The stationary jaw member has an outwardly hooked portion 5 secured to which is a serrated plate 6, forming one jaw of a machinist vise, and it will be noted that I 66 provide a recess 7 in the jaw member 6, and allow this jaw member to receive and hold round stock, bars or small pipe.

Formed integral with the aw member, is a projection 8, in which is received the jaw members 9 and 10, which are the stationary members of the pipe vise. These members are provided with teeth, as shown at 11, and are spaced apart for a purpose that shall ap pear later. The projection 8 has a further outward projection 12, which constitutes a plateor rest, and upon this plate or rest, I arrange a second plate 13 having a V-shaped slot 14 therein. This plate is secured by means of screws 15 and 16.

.80 A cylindrical member 17 passes through a suitable central portion in the jaw member and cylinder 4, and in this cylindrical member 17, the operating screw 18 is enclosed. This screw has an enlarged collar, or cylinder 19, formed integral therewith, and. through which passes the operating bar 20.

Formed integral with the cylindrical member 17 is the second duplex jaw member. This jaw member has an inwardly hooked portion 21. similar to the hooked portion 5, and upon this hooked portion 21, the jaw member 22 is secured. This jaw member 22 is serrated, and consists of a plate which is arranged parallel to the member 6, and which co-operates with the member 6 to complete the jaws of .the machinist vise. A projection 24: receives a member 25.

The member 25 is a plate retained in the member 24 by a bolt or set screw 26. This member constitutes a part of the pipe vise, and is therefore provided with a semi-circular recess in which are arranged the teeth 27. In operation, the plate 25 passes between the plates 9 and 10, so that the diameter of the operating circle may be reduced and/ or so that this pipe vise may hold pipes of smaller diameter.

The member 24 is also provided with a further projection 28, which approaches the projection 12 on the part 8. This projection 28 serves to form a plate, shelf, or support for a disk,and upon the member 28, I arrange a plate 29, having a V-shaped recess 30, arranged therein, and this plate 29 may be secured by means of a single screw 31.

At32, in Fig. 4, I show a plate which may be used as a substitute for the plate 29, and which will make it possible to retain cylinders or disks of small diameter. The added line 33, in Fig. 2, indicates the position of a cylinder or disk engaged between thejaws 13 and 29.

From the foregoing description, it will be noted that I have provided three distinct sets of jaws, each capable of accomplishing a different useful work, and yet all co-incidentally operated from a single operating means, and under most circumstances, used independ ently.

Upon the cylindrical member 4, I arrange a cap 34, secured by means of screws,'oneof which is shown at 35. I have not previously mentioned that the cylindrical member 17 has a slot therein, and a tongue not shown, formed integral with the member 34, enters the slot 36 in the member 17, and prevents this member 17 from rotating.

The operating screw 18 passes through the member 17, and projects a short distance beyond this member, and upon the end of the screw 18, I arrange a cap 37 having a part 38 thereof, almost, but not quite. completely severed from the capped body 37.

I will refer to this almost severed portion 38, as a plate. The body 37 and plate 38 are both screw-threaded upon the operating screw or worm 18. and when in such position, the screw 39, which passes through the plate 38 and into the capped body 37, is tightened down, whereupon the plate 38 and a cap 37 will clampingly engage the screw threads 18,

preventing the removal of the cap, and at that the machinist jaws 6 and 22 are at one side of the longitudinal center of the screw 18, and that the other jaws are arranged directlyopposite, or at the other side of the longitudinal center of the screw 18; that is, the jaws are one hundred and eighty degrees apart. This is for the purpose of simplicity of construction and increased strength, and it will be also noted that the jaws are so arranged that the presence of a set of jaws in no way limits the inoperability or efliciency of any other set of jaws.

At 40, I show an anvil plate, which is not new, but which is referred to only to explain the oblong surface shown in Fig. 2.

It will of course be understood that sizes of all parts may be changed at will; in fact, I do make this vise in all ordinary sizes.

Having carefully and fully described my invention, what I claim and desire to secure by Letters Patent is 2- In a vise, a plurality of projections adapted to approach each other, and a plate upon each said projection, each said plate being provided with a V-shaped slot therein, said plates being arranged fiat upon said projections and a portion of each projection extending beyond its associated plate, to prevent passage through said V-shaped slots.

the same time, preventing the screw 18 from I being withdrawn from the cylindrical member 17.

It will of course be understood that as in ordinary vises, the screw 18is screw threaded through the body cylinder 4, and it will be observed that when the vise is fully opened, the cap 37 will engage the projection from the member 34. which enters the slot 36, limiting the opening of the jaws, and preventing.

them being separated.
