2,769,384 Patented May 31, 1955 ice '2,7e9,3s4 PonTAnLE PIPE vrsn Thomas J. Harris, Forty-Fort, Pa. Application June 24, 1954, Serial No. 439,035 11 Claims. (Cl. 81-41) This invention relates to pipe vises, and more particularly to a portable pipe vise.

There are a variety of pipe vises on the market today all of which, while they serve their intend-ed purposes, possess inherent disadvantages which the present invention is designed to overcome. Some of these vises are fixed installations requiring that they be fixedly secured in a suitable location, such as a work bench, making them highly impractical for portable usage, as is required by plumbers and pipe fitters. Other of these vises are portable, but are found to be heavy and therefore burdensome for a plumber to carry about, especially when he must climb several flights of stairs. In addition, currently available portable pipe vises are rather intricate in design, contributing to the cost thereof and the length of time required for assembling said vises at the work site. It has also been found that the presently available portable pipe vises have a tendency to ride or slip about the floor while threads are being cut in pipe held thereby.

It is an object of this invention, therefore, to provide an improved portable pipe vise.

It is another object of this invention to provide an improved portable pipe vise which is light in weight, requiring a minimum of physical exertion to carry it about.

It is a further object of this invention to provide an improved portable pipe vise which is of such simple construction as to be capable of assembly, ready for use, in a few seconds.

It is still another object of this invention to provide an improved portable pipe vise which will resist any tendency to slide about the floor While cutting pipe threads therewith.

A further object of the invention is to provide a lowcost portable pipe vise.

These objects, together with other objects and advantages to be derived in utilizing the present invention, will become apparent from the following detailed description and from the accompanying drawings describing the preferred embodiment of this invention in which similar numerals refer to similar parts throughout the several views.

Figure 1 is a perspective view of the portable pipe vise of this invention in assembled position ready for use.

Figure 2 is a side elevational view of the portable pipe vise in a folded, disassembled condition, illustrating the manner in which it may be carried about.

Figure 3 is an enlarged front elevational view of the vise-portion of the present portable pipe vise, partly in section and with parts broken away, and showing the vise legs in an unlocked position.

Figure 4 is an enlarged side elevational view of the vise-portion shown in Figure 3, partly in section and with parts broken away, showing the vise legs in an unlocked position, and illustrating the telescoping pipesupport member.

Figure 5 is an enlarged front elevational view of the present portable pipe vise, with parts broken away, showing a pipe being held thereby, and illustrating the manner of maintaining the vise legs in a locked position.

Referring to the drawings, and particularly Figure 1 thereof, the portable pipe vise of the present invention is shown and referred to in its entirely therein by the letter V. This portable vise V consists of a vise-portion 10 supported by forwardly extending

adjustable legs

11 and 12, a rearwardly extending horizontal pipe-support member 13, and a rear leg 14.

Looking now at Figures 35, it will be seen that the vise-portion 10 consists of a pair of vertically disposed

tubular members

15 and 16 integrally joined near their lower ends to a cross-bar 17, and provided with a plurality of

notches

18 and 19 about the peripheries of their lower ends for a purpose to be described below. Fixedly attached to the cross-bar 17 by means of screws 20, or other suitable attachment means, is a vise bed 21 having stepped-teeth 22 in its upper surface for securely gripping a pipe. Cooperating with the vise bed 21, and slidably retained between the

tubular members

15 and 16 above said vise bed, is a movable head 23 having a jaw member 24 fixedly attached to the bottom thereof. The said movable head 23 is adapted for a vertical sliding movement between said

tubular members

15 and 16, as guides, under the control of a threaded rod 25 which is pivotably connected thereto. This rod 25 is threadably received in a tapped yoke 26, which rests freely upon the upper ends of the

tubular members

15 and 16, and is provided with a horizontally slidable handle 27 for manipulating said rod. The upper ends of the

legs

11 and 12 are slidably received in the

tubular members

15 and 16, and in the yoke 26 in apertures provided therefor in said yoke, and said leg ends are flared so as to provide retaining flanges 28 and 29. The

legs

11 and 12 are also provided with diametrically disposed looking

studs

30 and 31, located adjacent to the lower ends of the

tubular members

15 and 16, and adapted to be received in the

notches

18 and 19 therein for a purpose to be described below.

The rearwardly extending horizontal pipe-support member 13 consists of a horizontal tubular casing 32 integrally attached at one end to the cross-bar 17, and having a telescoping extension 33 slidably retained in the free end thereof, as shown in Figure 4. Fixedly attached to said telescoping extension 33 is a V-shaped pipe cradle 34 adapted for grasping the pipe in supporting fashion, as shown in Figure 1. Referring to Figure 4, it will be seen that the underside of the tubular casing 32 is provided with a tapped boss 35 near its free end, which threadably receives a set-screw 36 for maintaining the extension 33 in a fixed adjusted position. Integrally attached to the tubular casing 32, as by welding or other suitable attachment means, is the downwardly depending rear leg 14, above referred to. This leg, it will be noted, lies centrally of the forwardly extending

adjustable legs

11 and 12, so as to provide a tripod support for the vise-portion 10 and the pipe-support member 13.

In order to preclude the present vise from riding or sliding about the floor while threads are being cut in pipe held thereby, the forwardly extending

legs

11 and 12 are provided with

rubber shoes

37 and 38, while the rear leg 14 carries a rubber suction cup 39 which is adapted to securely attach said leg to the floor when a downward force is exerted thereon.

vise portion of the Operation In using the present invention as a portable pipe vise, the

legs

11 and 12 may be rotated rearwardly within the

tubular members

15 and 16 and the vise carried about,

as shown in Figure 2, or extended forwardly in pipesupporting fashion, as shown in Figure l.

In setting-up the vise from the portable condition of Figure 2 to the supporting position of Figure l, the handle 27 is rotated in a counter-clockwise direction so as to raise the movable head 23 a sutficient distance to unlock the legs 11 and 1'2. The legs are then pulled downwardly a slight distance so as to release the

locking studs

30 and 31 from the

notches

18 and 19, and the legs are rotated forwardly until said studs are in alignment with the notches l8 and 19 in the sides of the

tubular members

15 and 16, respectively. This relationship is shown on an enlarged scale in Figures 3 and 4. Referring thereto it will be seen that with the

legs

11 and 12 in a forward, unlocked position, the

studs

30 and 31 are free from the notches i8 and i9, and yoke 26 rests freely upon the upper ends of the tubular members 15 and in. It will also be noted that a substantial gap exists between the fixed bed 21 and the movable head 23, and that the flanges 23 and 29 lie above the yoke 21$ with a gap therebetween.

The major advantage of the present invention, to he described now, is that the locking of the

legs

11 and 12 in their forward position and the anchoring of a section of pipe within the vise-portion ll) of the vise is a simultaneous operation which is accomplished with a minimum of effort and in a minimum length of time.

A length of pipe is inserted into the vise so as to lie upon the fixed bed 21 and the cradle 34, as shown in Figure l. The telescoping extension 33 may be adjusted within the tubular casing 32 to accommodate various lengths of pipe, and maintained in a fixed adjusted position by means of the set screw 36. With the pipe thus supported, the handle 27 is turned in a clockwise direction so as to turn the threaded rod 25 within the tapped yoke 26 causing the movable head 23 to move downwardly between the

tubular members

15 and 16. When the jaw member 2-?- on said movable head contacts the pipe, said head comes to rest, but the rod 25 being pivotally attached thereto will continue to turn, causing the yoke 26 to travel upwardly thereon, due to the screw action of the threaded relationship therebetween. As the yoke 26 contacts the flanges 28 and 29 in its upward travel, an upward force is exerted thereon, which force causes the

legs

11 and 12 to move upwardly within the

tubular members

15 and 16, seating the

locking studs

36 and 31 within the

notches

18 and 19. This action is illustrated clearly in Figure 5. The

legs

11 and 12 are now locked in their forward, pipe-supporting position of Figure l. erted manually upon the rear leg 14 so as to cause the suction cup 35 to adhere to the floor, which force will ordinarily be supplemented by a maintaining force consisting of the Weight of the pipe and the device, and the vetrical component of the torsional force exerted in the cutting of threads on the pipe. The joint holding action of the suction cup 39 and the

rubber shoes

37 and 33 precludes slippage of the device during the cutting of pipe threads.

To disassemble the vise for portable carriage, the handle 27 is rotated counterclockwise until the yoke 26 is set free of the flanges 28 and 29 and the movable head 23 is raised above the pipe. The pipe may then be removed and the telescoping extension adjusted inwardly within the casing 32 and locked therein. A downward pull may then be exerted upon the

legs

11 and 12 until the

locking studs

36 and 31 are free of the notches l8 and 19, whereupon the said legs are rotated rearwardly until said studs align with rearward-facing complementary notches. The handle 27 is then again rotated clockwise until said studs are raised into the notches, locking the

legs

11 and 12 in the position shown in Figure 2. The vise may now be carried about in the manner shown therein.

It will be noted from the above description of the pres- A downward force may now be exout invention that a novel portable pipe vise is presented which overcomes the many disadvantages of existing vises or" this type. in particular, it has been seen that the present portable vise may be assembled with a minia mum of physical effort and in a minimum length of time. And due to the relative simplicity of the device, the total weight thereof is reduced considerably as compared with present-day portable vises, presenting an ideal portable pipe vise for use by plumbers and the like. The cost, of course, is reduced accordingly.

In addition, this vise is resistant to slippage during the cutting of pipe threads, and is readily adaptable to supporting various lengths of pipe by virtue of its telescoping pipe-supporting feature described above.

Although the present discussion of this invention has been limited to the above-described preferred embodiment, variations thereof are possible without departing from the scope of the invention. It is therefore not intended that the invention be limited to the particular embodiment disclosed, but only to the inventive concept as defined in the appended claims.
