I 3*Glaimsi' 1 My'invention relates to Vises, and "more" par ticularly to a quick actin'gpipe' vise.

In cutting and threading pipe, particularly onv larger jobs, or on jobs in which a large amount of the same size of pipe is used, it is mghlyjid esirable to leave the jaws of the vise set in a fixed It is a particular'purpose of, my invention to.

provide a vise in which it is unnecessary to adjust themovable jaw member thereof relative to the yoke-like member after the same has onceb'een adjusted to properly clamp a piece of pipe be'-. tween the jaws of the vise, as long as the same size pipe, or similar member, circular in cross sec. tion, is placed between said jaws. While a member circular in cross section is referred tohereim lt'is'to be understood that any member that can be'clamped between the jaws of a pipevv'ise. can:-

constitute the work inserted between thejaws of myimproved vise.

It is a'particular purpose of my invention to provide a vise in which saidabove. referred toyoke-like member is provided with the usual mounting'for a rigid jaw slidable relative-to the yoke-like member, and screw-threaded means for adjusting the position of said rigid jaw relative to said yoke-like member, 'to thus adjust'said"'jaw to proper pipe clamping position, whenthe "yokeilike member and base member carrying the jawsare in propercooperative relation, which yoke likemember is provided with means for successively bringing the yoke-like member into'what'. isordinarily referred to as a closed'position, or"

aposition adjacent thebase member; and'lock ing said yoke-like member to said base member with the jaws in clamping engagement'with' the work.

It is a further purpose of my invention'to'prm vide a vise of the above mentioned character with alever for'performingthe operation ofclos ing the vise and clamping the jaws tothework; which also serves as means for sucoessively're leasing the jaws from the work and opening the vise-so that the work can be removedthierefrom.

Mans is thus-providedwhereby; witki a*single== 6 is a fragmentary torr plaw view-' of the of a lateral projection on said base member, this,

also being common to Vises that are provided with hook-like members for detachably securing one of the legs of the yoke-like member to the base member. Said base member is further provided with mounting means H for detachably securing a rigid serrated jaw l2 of a substantially V-shaped character, to the base member.

The yoke-like member is of a substantially U-shaped character, having a transversely extending portion I3 and a leg I that is substantially parallel to the leg 8; The inner faces of the legs 8 and H are provided with guides l5 for a slidably mounted member I6 that detachably carries a serrated jaw H, such as ordinarily provided on pipe Vises, it being common to have the jaw I1 extend between a pair of serrated jaws l2 on the member although the particular arrangement of these jaws to clamp various sizes of pipe therebetween can be varied, the particular jaw structure not being part of my invention. The slidably mounted member I6 is swiveled in the usual manner to a screw-threaded stem member l8, so that said screw-threaded stem can be rotated relative to the slidable member IE, but is held against endwise movement relative to said member I6. Said stem screW-threadedly engages an internally screw-threaded socket member l9, provided in the transverse portion I3 of said yoke-like member in the usual manner, and has a head thereon for receiving the clamping bar, or lever 2|, having the usual end enlargements 22 thereon, be rotated to advance the jaw l1 toward the jaw, or jaws, 2, or move said jaw l1 away from said jaw, or jaws, l2, either to firmly clamp a piece of work, such as the pipe 23 therebetween, .when said yoke-like member is fixed relative to the base member, or to release the Work.

Said yoke-like member is provided with an enlargement the junction of the transverse portion I3 and the leg I4, which is providedwith a circular bore 25 for rotatably receiving a substantially cylindrical rotatable adjusting member 26. Said rotatable member is straddled by a pair of ears 21, provided on the curved end portion 28 of a lever 29,'said curved end portion being shown as being made of a separate piece of material, welded to the tubular member 29 in the drawings, although the members 29 and 28 can be made integral if desired. The ears 2'! are fixed to the rotatable member 26 by means of a pair of pins 30 located near the periphery of the rotatable member 26,

whereby said stem can 24 thereon at the outer corner of 4 thereof remote from the hook-like member 32, which ears embrace the ears 2'], but are free to slide thereon. The rotatable cylindrical member 26 is provided with an opening 35 therein that is eccentric to the center of said member 25, and which rotatably receives the shank portion 36 of a headed screw-threaded member, the head 31 of which is in engagement with the outer face of one ear 34, and the screw-threaded end of which screw-threadedly engages in an opening 33 in the other ear 34, and is provided with a lock nut 39 thereon so as to lock the parts in adjusted position. The headed screw-threaded member is screw-threaded into such adjusted position that there will be no looseness of the parts, and yet the ears 34 are free to swing relative to the ears 2'! to permit easy operation of the device. It will be noted that the arrangement of the parts is such that when the headed screw-threaded pivot member is in position the ears 34 will hold the pins 33 in position to fixedly lock the lever 29 to the rotatablemember 26.

The location of the opening 35 is such that when the lever 23 is in the position shown in Fig, 2 the shank 33 of the pivot member for the hook-like member 36 will be swung around to a position on the opposite side of a line, that could be drawn through the axis of rotation of the member 26 and the point of engagement of the hook like member 32 with the abutment ID, to that which the member 36 assumes when in the position shown in Fig. 4, and considerably closer to the leg I4 than in the position shownin Fig. 4, which will release the faces I3 and 33 from clamping engagement with each other, and the jaws l2 and H from clamping engagement with the work and permit the swinging of the hook-like member 32 to the position shown in Fig. 2. On the other hand, when the parts are in the position shown in Fig. 4, the member 26 will act as an eccentric clamping means to clamp and lock the faces l0 and 33 together and the jaws l2 and I! to the work 23.

Means is provided for swinging the hook-like end 32 of the member 3| out of the position in alignment with the abutment it), said means comso that the lever 29 and the rotatable cylindrical member 26 will rotate about the axis 25 as a unit.

My improved vise is of the socket provided with an elongated hook-like member 3| thereon, which has the usual hook portion 32 that is adapted to engage with the flat faced abutment l0 having a substantially flat face 33 thereon engaging said abutment. Said hook-like member is provided with a pair of ears 34 projecting endwise therefromatthe end strap-like member 43, may be provided prising a finger-like extension 43 on the member 28,'which engages an abutment 4| provided on the enlargement 42 on one of the ears 34 provided on said hook-like member 3| for swinging the hook-line member 3| around the member 36 as a pivot to bring it out of aligning position with the abutment I0.

Any suitable means, such as the U-shaped on the leg I4 of the yoke-like member to serve as means engaged by the hook-like member 3| to swing the entire yoke-like member about the pivot 9 into open position, so as to permit ready removal of the work 23 from the vise. Preferably, the lever 29 is provided with a handle portion 44, which is knurled, so as to prevent slipping of the hand on the handle, and is provided with a lateral enlargement 45, which will serve as guard means to prevent the operators fingers from being pinched between the member 43 and the lever 29, or other parts that are adapted to move in close adjacency to each other.

The hook-like member 3| may be made integral with the member that carries the ears 34, or the member that carries-the ears 34 may be made of a separate piece and welded thereto, as shown in the drawings.

'In operation, the work, such as the pipe 23, is

,,flr st placed in position on the base member, after which the yoke-like "member of the-vise and the hook-like member are moved into the position shown in Fig. 1, by means of the lever .29. Before doing this thejaw fl is moved to a position where it will not interfere with the clamping action between'the parts l and33, and will not be adjusted into position in engagement with the work until after the yoke-like member has been moved into the position shown in Fig. 1. After such position of the yoke-like member has been reached by adjustment of the lever 29, then the lever or'handle 2! is rotated to rotate the screwthreaded member K8 in the usual manner to firmly clamp the work between the jaws l2 and I1. After the necessary operations have been performed on the piece of work 23, the vise is released from the work without disturbing the adjustment of the screw-threaded member 18, by moving the lever 29 to first release the hook from the abutment Iii and then swing the oke-like member into a position to open the vise, to permit removal of the work, through the position shown in Fig. 2. The next piece of work 23 of the same outside diameter of the piece of work previously clamped is then inserted into the vise, being laid upon the jaws provided on the base member 6, and by means of the lever 29 by a single counterclockwise movement thereof, as viewed in Fig. 1, the yoke-like member is swung into closed position, or toward the base member about the pivot 9, the hook-like member 3| is moved into alignment with the abutment I0 by the action of gravity as the yoke-like member moves into position, and is then moved toward the abutment I!) to firmly clamp the work 23 between the jaws l2 and H when the lever 29 reaches substantially the position shown in Fig. 1.

It will thus be seen that both release of the work and opening of the vise is done by a single movement of the lever 29 and the closing-of the vise and clamping of the work is done similarly by a single movement of the lever 29 inthe opposite direction, making it possible to very rapidly engage and disengage work from the Vise, as is highly desirable where a large number of pieces of the same diameter are to be worked on, as in cutting lengths of pipe and threading the same.
