' To aZZui/zom 2'22 may concern/ T "Be it "known that, I, HnzgnrA, Rii'onn; a citizen of the 'Ui ited ,;-St;ates, residing at Brechen1"idge,-in the county of Summit and, State ofIGolorado, 'hayejinvented' certain new and "useful Improvements in Combined Tools and Clamps; and Ldofdeclare the following-to be a full, clear, and exact'descruo; tion. of {the invention, such as; will, enable; others. skilled in the, art to -which; it apperi g tains tohlnake and'tuse, the same, reference being had to the accompanying drawingsg and to the Characters of reference marked:

The ends o-fthe jawsfmayfbe "con structed in Various ways so as to adaptthein for Various uses. I have shown the jaws provided with transversenotches by means 105 of which a round meinbe'r'inay bec'lampedor a square nut grasped and turned. The end of the jaws have been shownas provided with V-shaped grooves 14 in which a round or square member'mayebe clamped. The remaining portions oft'he adjacent sur v faces may be flat and smooth or roughened ioo 1 endeavored to describe the construction and rotatable disk has spiral threads on one side- 1 in any way that may be best suited for the work thatit is to do. In 5 Ihave shown a modification in which both of the j awsare identical and constructed like that indicated by numeral 2 in Figs. l to 3. s As the removable-part 4 has been omitted in this construction, it becomes impossible to 1 assemble the parts if afnutmadeof asingle piece s used." The nuthas therefore been Qas flfNand 13.

made in ,two parts which I have indicated These parts are held in as- 2 isembled relation byth'e screws 15. Myde- V vice when constructed in the manner shown:

, in Fig. 5 is more easily assembled than when constructed in the m'anner'shown' and described in'liigs. 1 to 3.

In 'Fig '6, I have 'shown'a lock: nut 'constructe'd in accordance withthis invention:

1 Insteadiofhaving jaws like'thos'e shownin but of somewhat different shape; the jaw Figs. 1 to 5,. the jawsemployed are similar marked 2A1'corres'ponds to jaw 2'ij'nI ligf3 I and j aw'34 corresponds to jaw 3, while the removable part 4 'corresponds tomembert' i in Fig. 3. One endjoi thejaws Ql and 3* hasfiat sides which cooperateto form a J square portion 16' that can be engaged by a may be put". I desire to oallattentionto the.

wrench. {The adjacent surfaces are curved and threaded sov as to engage the 'bolt 17;

Afterf-the -nut has been tightened it is clamped against the sides of the bolt by 'means of the clamping action of the nut 1. This nut or clamp may be employed as a connector forwires or other members.

'In'the above illustrations Ihave merely show mm": the uses to which the device -factthat'this device mayjbe employed for aJlarge variety ofusesandthat the shape of the jaw member can be varied as maybe I requlred to make them adapted toperform the particular function that they are to per% form. My invention in its broadest aspect relates'to the use of a nuthaving its opposite surfaces provided with spiral threads V ythatengage similar threads on the end walls 7 ofthenot'ches in the jaws. Thisis an al- 'r together 1 different combination than that which is found inlathe chucks where the I claim as new is:

adapted to engage walls of said notches-whereby when the nut is rotatedfwith respect to the jaws, the latter 7 V only. By having" the oppositesurfaces of allelmotion is obtained and the nut serves to strengthen the jaws.

Having now described my. invention, what "1. Ina device of the c1as's combination, a pair of aligned awmembers adapted to be moved towardsor away from each other, said jawshaving each'a'notch with parallel opposed surfaces provided wlth spiral threads'and a nut having its opposite sides providedwith spiral threads the spiral threads in the will'movetowardsor away from eachother with a' parallel movement, one of said jaw members having a removable portion, one end of which formsoneofthe opposing surfaces of the notch. 1

2. A clamping device comprising, incom-I blllittlon, two opposed aw members of sub stantia-lly' the same shap'e and size,' eaoh or sa d aw, membershavlng a notch whos opposed surfaces are formed with threads,

one of said jaws having a portion thereof removable, said removable portion-forming one side wall of, said notch, anda circular nut adapted to lie in said notches, said nut having its" opposite" sides provided with spiral threads adaptedto cooperate with the spiral threads on the opposed walls of said notches.

A clamping device comprising, in com. f

'bination, two opposed jaw members of sub stantially the same shape and size-each of said jaw members having a notch whose opposed surfaces are formed with threads,

one of said jaws having a portion thereof removable, said removable portion form ng one side wall of said notch, .a circular nut ing its opposite sides provided with spiral threads adapted to cooperate with thespiral threads on'the opposed walls of saidlnotches "adapted to lie in said notches, said nut havr and guiding lugs on each j aw for embracing the other jaw and for guiding thesame.

In testimony whereof I aflix my signature.
