ROY PARMELEE, OF CHICAGO, ILLINOIS.

VISE.

Application filed August 6, 1915, Serial No. 44,078. Renewed. August 28, 1919.

To all whom it may concern:

Be it known that I, For PARMELEE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and use ful Improvements in Vises, of which the followingis a specification.

My invention relates to a vise, more particularly that type intended for pipe work, and the object thereof is to provide a simple, efiicient and reliable vise of this character. According to my invention, 1 utilize parts similar to certain parts of a Stillson wrench, and by preference provide the vise with a girth for pipe work. The various features of advantage and utility of my constructions will be apparent from the descriptions hereinafter given. 1

I11 the drawings, Figure l is a vertical sectional elevation of a vise representingone embodiment of my invention; Fig. 2 a plan view of one of the jaws; Fig. 3 a detail sectional view showing the manner of the clamping of the vise to a bench or other support; Fig. 4 a similar view to Fig. 1 but illustrating a modified form of construction; Fig. 5 a horizontal section on the line 55 of Fig. 4; Fig. 6 a sectional plan view on the line 6-6 of Fig. 4:; Figs. 7 and 8 detail views of one of the jaws; and Fig. 9 a sectional view of the device with the girth removed.

Referring to the particular embodiment of my invention as'herein shown, the vise com-- prises a frame consisting of a base portion 1, upright standard or post 2 and a connecting cross piece 3, all preferably cast in one piece. The base is preferably but not necessarily provided with a longitudinal channel formed by the upwardly directed side walls or flanges 1, which channel is of a size to conveniently accommodate the shank portion 4a of one of the jaws 4 of the vise. This jaw is the same as the corresponding jaw of an ordinary Stillson wrench, being the movable jaw thereof, and as in the Stillson construction the shank is provided with the screw threads 4" on which screws the adj usting nut 5. This nut bears against the rear portion 2 of the standard 2 with the result thatas the nut is screwed-in one direction or theot-her, the jaw 4. is moved in or out, that is, toward or away from the other jaw.

This jaw 6 is in the form of a block having a toothed or serrated front face utilized when the device is acting as an ordinary vise. This block has a rearwardly extending por- Specification of Letters Patent.

tion 6 which is pivoted upon a cross pin 7 extending transversely of the frame. The block is carried by the lower end of a force feed screw 8, which screws through the cross piece 3 of the frame, being provided at its upper end with a handle 9. As shown, the block 6 is removably connected with the lower end of the feed screw by means of a plate 10 which is secured to the top face of the block by means of the screw 11. This plate has a slot 10 registering with a groove or socket 6 in the top of the block through which extends a slot and into which socket extends the flange head 8 of the lower end ofthe feed screw. The extreme rearward end of the slot l0 is enlarged to a size to permit this flanged head to pass therethrough when the block is in a position to be removed from the feed screw.

The device thus far described is adapted to be used as an ordinary vise, such shown in Fig. 9, where, however, a different form of block is employed, it being understood that when the complete device which also includes the girth is to be used as an ordinary vise, such girth, as shown in Fig. 1, is removed.

Describing the operation of the device when used as an ordinary vise, that is, without the girth, the pipe or other object to be clamped is placed between the two

jaws

4 and 6, the aw 4 being adjusted according to the size of the object. Thereupon the aw 6 is caused to swing downwardly and for wardly by the action of the force feed screw 8 with the result that the object is firmly clamped between the two jaws. \Vhile both jaws are movable, the jaw 4 may be considered the fixed jaw after the adjustment is obtained and the jaw 6 the movable jaw, which is adapted to be moved so as to bring its clamping surface toward the other jaw and thereby clamp or grip the object. In the present instance, the movement of the jaw 6 is a swinging movement on the pin 12 as an axis thereby giving the desired downward and forward movement of the jaw and consequently of its gripping surface.

Referring to the complete device, as shown in Fig. 1, I provide a suitable sectional girth 12 whose innermost link or section has parallel extensions 12 whereby such girth is pivotally connected to the lower portion of the block 6 by means of the pivot pin 13. The block has at its lower front edge at the base of the serrations a shoulder 6 adapted to bear against the hook or lip 12* on the outermost section of the girth for locking and holding the girth onto the pipe shown at A.

Describing the manner of use of this complete vise, the pipe A is laid in the open girth and the outermost section thereof is thereupon engaged with the jaw 6 by having the hook or lip 12 positioned under the shoulder 6 of said jaw, as clearly shown in Fig. 1. It will be observed that at this time the girth is resting upon the top surface of the vertical lugs 1 with the result that when the screw 8 is screwed downwardly, thereby moving the jaw 6 downwardly, the girth fulcrums upon said flanges and also upon the pins 7 and 13 while the jaw bears downwardly upon the lip or shoulder 12". As a result the pipe is firmly clamped by the girth, any desired pressure being obtained by screwing the force feed screw 8 downwardly. Then the device is thus used for pipe work, the jaw 4 may be left in place but in position, so as not to interfere with the girth, as shown in Fig. 1, or such jaw may be removed altogether if desired.

The device may be attached to a bench or other support in any suitable manner and in Fig. 3 I have shown a simple and convenient form of clamping device consisting of an L-shaped rod 14: passing through the base of the frame with a screw-threaded portion extending alongside of the bench B or other support extending through a right angled plate 15 enveloping a lower corner of the bench and having a toothed portion 15 adapted to enter the underside of the bench.

By means of a thumb-nut 16 screwing onto the lower end of the rod 14 the device is planked to the bench. If desired the device may be more or less permanently fastened to the bench or other support by means of bolts or screws (not shown) passing through the openings l shown in Fig. 1.

In Figs. 4 to 9 I have shown a modified form of device in which the parts, that are substantially the same as those already described, are provided with the same reference characters. In this construction the block 17 corresponding to the block 6 has a vertical movement in the standards 2 of the main frame, the same being also guided by means of the pivot pin 18 which pivotally secures the innermost section of the girth to the lower end of the block, and whose outer ends are adapted to travel vertically in the slots 2 of said standards. As shown in Figs. 4 and 5 the lower end of the screw 8 extends into a socket in the top of the jaw 17 and has a circumferential groove S which is engaged by the parallel limbs of a U- shaped or hair-pin shaped retainer 19 which.

is forced into openings 1? through the rear s1de of the jaw 17 and into said socket there- 1n, thereby detachably holding the screw and.

"is-removable so as to permit the entire girth to be removed from the jaw 17 By preference I interpose between the back of the block 17 and the web connection 2 of the standards a loose plate 20, whose upper portion is of course cut away to accommodate the retainer 19 in its movements. This plate is used to avoid the necessity of machining the coacting parts.

In Figs. 7 and 8 I have shown a modified form of construction having the retainer in the form of a set screw 21 and having another form of jaw 22 in which the opposite sides thereof having projecting flanges 22 adapted to slide against the front edges of the vertical standards 2 while a back extension 22 extends between such standards.

Describing the construction shown in modification of Figs. 4, 6 and 9, and first describing the operation of the device when used for pipe work, the girth is opened and the pipe A is laid therein whereupon the girth is closed with its lip 12 engaged by the lower shoulder 17 of the jaw 17. The screw 8 is thereupon screwed downwardly forcing the jaw 17 downwardly and clamping the pipe, it being understood that the girth at this time is resting and fulcrumed upon the top surface of the flanges 1 of the base of the frame.

hen the device is used for ordinary work the girth is removed as shown in Fig. 9 whereupon the jaw 4 of the wrench is called into service. The pipe A or other object is placed. between the two jaws and the screw 8 thereupon screwed downwardly thereby bringing the gripping surface of the jaw 17 downwardlyand forwardly. with respect to the gripping surface of the other jaw 4 and into engagement with the pipe.
