To all whom it may ccmccm:

Be it known that I, Roemer E. JACK a citizen of the United States, residing at Milwaukee, county of`Milwaukee, and State of "Wisconsin, yhave invented new and useful Improvements in Clamping-Tools, of which the followin 'is a specification. A

. My invention relates tob improvements 1n clamping tools and it, pertains more especially, amon other things, to the construction of the evice for quickly adjustin the movable clamping member of the o' amp" nearer to or farther from the stationary member preparatory to a plying the action of a screw to said movab e clamping naem- 4 the op )osit'e end of the screw threaded sleeve from hat shown in Fig. 2, and Fig: 5 is a transverse section of the slidable adjustable rod of the movable clamping member.

'Like parts are identified by the same reference numerals throughout the several views.

My clamp comprises, among other things, the ri 'd yoke 1 provided at/one end with :n.ixe clamping member 2 and at its op posite end with a stationary screw threaded sleeve 3 for the reception of the revoluble 'screw threaded sleeve 4.-

5 is a movable clampin member, which is connected with one en 'of the slidable member 6 through an ordinary ball and socket jointv 7. The slidable member 6 is provided with a `plurality of radial lugs 8 i extending from opposite sides thereof and said lugs are respectively adapted to bear against the end member 9 of the revoluble sleeve 4. .The end member 9 is provided 4with an elon atedslot 10 for the passage of the radia lugs 8, whereby when the slidable member 6'is turned so as to bring said radial lugs 8 in alinement with sai aperture 10, said slidable member G may be freely moved in either direction through the sleeve 4. 'iihus it iis obvious that when desirous to apply the clamping tool to an obj-ect, the stationa -bearingmember 2 is placed upon one :side thereof, when the slidable member 6 is moved until the 'opposmg clamping member .5 is brought in corntact with the opposite side of said object. When this is done, the slidable member 2 is Irevolved together with the screw threaded sleeve 4, -whereby great pressure may be applied to said object through the action of said screw jthreaded .sleeve 4 in the screw threaded sleeve 3, while said slidable member 6 is prevented from m'oving back in said revoluble sleeve 4 by contact of said radial lugs 8 with the op osing sides 11, 11, of said end member. T e revoluble sleeve 4 is provided on its two opposing sides with inwardly projecting beads 12, .12, against which theradial lugs 8 of the slidable member 6 are adapted to contact, and the slidable member 6 is revolved, whereby a revoluble movement is communicated from said slidable member 6 to said sleeeve as said slidable memberis turned.

1 3 is an operating handle, by which the slidable member 6, together with the sleeve 4, are revolved in their supporting bearings. Thus it will be understood that the clamping members 2 and 5 are adjusted nearer to and `fartherfrom each other against the object to tbe clamped, by the movement of said slidable member 6;that when said clamping members are thus adjusted and the handle 13 is revolved, said clampin member 5 will be moved forwardly andwill be caused to bear with great pressure against the object to be clamped. The shank 14 of the slidable' member 6 is of such width as to bear at its opposing edges against the opposing walls of the sleeve 4, whereby when the radial lugs 8 have been moved forward out of contact with the beads 12, the opposing edges of said shank 14 are adapted as the slidable member is revolved, to contact with 1. In a 'clam ing tool of the described stationary clamping member and at its opposite end with a screw threaded sleeve, an

open revoluble sleeve having screw threadedv bearings in said stationary sleeve and provided at one ond only with inwardly extending contact bearings, a slidable member supported within said sleeve and provided with a series of radial lu s adapted to bear against the outer en of said revoluble sleeve, and means connected with said slidable member for revolving the threaded sleeve in said stationary sleeve.

2. In a clam ing tool of the described class, the com mation of an integrally formed yoke provided at one end with a stationary clamping member and at its oppo- -site end with a screw threaded sleeve, an

open revoluble sleeve having screw threaded bearings in said stationary sleeve und provided at one end only with inwardly extending contact bearin s,A and near its opposite end With'longitudmally arranged inwardly extending beads, a slldable member supported Within Said sleeve and provided at one end with a clamping member revolubl connected therewith, at its oppositeend wit an operating handle, and upon its respective sides with a series of radial lu s, said lugs being adapted to bear against t e outer end of said revoluble sleeve, the radial lugs of said slldable members being adapted as the latter is o urned, to Contact with said' longitudinal beads and turn saidsleeve in lts threaded bearings.

In testimony whereof I aix my signature in the presence of two witnesses.
