aclamp having portions at one end ,of eachot two arms for rmlyiiholdingseparate.

parts tobe joined and having. means to-0perate the larms tolli-bringing together' the y parts of the work .to be' joined and secu-rely.,

holding them in abutment.

Another object is to provide a having a portion on eachv of two arms thereof each for holding apiece of work suchas wood to be glued as in ljoinery, .together with means to adjust the portions of the work to their positions 'with respect to one another as Vtheir positions for permanent connection, and'also to provide .manually operated means to .separate the" portions for gluing and for returning fthem to their abutting positions.

Other yob'ects and advantages ywill ap.-

pear' in the `following' sp'ec-ication-adeil` by4 the accompanying drawing wherein;

Figure 1 is an elevation of the clamp of my invention. i

Figure 2 is a side elevation of 'a portion ot one of the' arms oi' the olampfshowing work holding devices illustrated in FigureY 1 attached thereto. 1

Figure 3 is a detail of aswivele'd collar in one ofV the arms ot the clamp.

Figure t is an elevation showing the edges" ot portions of the two" arms of Athe Yclam-p, and

Figure 5 is a plan of a work holding device shown in Figures 1 and 2.

The characters 1 and 2 represent two arms each bent in its own plane to about the form shown in Figure 1 and resembling an ice tongs in this instance, said arms being pivoted on one another at 3. The upper end of each arm is bifurcated as shown in Figure 8 and a bored and threaded collar l is swiveled therein on gudgeons 5, a rod 2 having both a right hand and a left hand thread engages in the threaded'bores of said collars. Y

The opposite end of each of the arms ter minates at an enlargement 6, Figure 2, each having a socket 7 to receive the stem Soi a member 9, the latter abutting against said enlargement as shown in both Figures land 2, and a hand screw 6 in the enlargement engages the stem 8 for securing the member `9 -inany position of adjustment. The extremity of each said member 9 Vhas two spaced portions 10 paral'leling the plane ot the clamp 'through each of which extendsa hand screw 11 bearing a plate 12'on fits inner end, the two plates adaptedifor clamp- 'ing. yvork betweenl them'.

rThe member 9hasA a socket 13, igure 5, also lparallel-i'ng 'fthe plane .of jthe clam-p jand this receives astem 14 heldfbyla screw 14, a member 15 being carried bythe stem whichl is similar to the Amember-9 in that Vit comprises extensionsl each receiving a.

hand screw 17 having a plate 18 for clam-pmgv work, it being observed that theme-inbers 15 extend in tlirejdirect'ion of one an' other as shown in Figure 1. I l

Since it is thefpurpose-to clamp the work between -tlfiefblates 12fof the member 9, or between the plates 18 of the member w15, or both, .and since the work mayvery often be of 'som-e considerable size 'I .preferably ofisetthe lower ends of the; arms l, 2 above the enlargementsr 6 ,so thatwthe, work can eX.- tend beyond the pivotof the arms in a dif-l ferent-,planeromthe lonjg ends of said) arms as indicated-` in Figurell.

In; operation, wherejtwo portions of Vworlr are lto be glued togetherl onL the `lineA,v for`-` l'y .abut at `said line A bringing them into the same plane flush wi-,th onefan'other thegadjustment ofthe' screws 11,' 17.

vI-Ia-ving :accomplished this exact set'tii'igVV of the w'orkof the thread bar or rod 2 is turned in a direction to separate'the parts of the work sulficiently to apply glue to the edges or surfaces to be joined, whereupon a reverse direction of movement of said threadbar brings the parts into exact abutting positions as before and may there be held as long as desired or until the glue has set. i

. For certain jobs the members 9 may be swung on their stems 8 within the enlargements 6, or again, the members 15 may bek similarlyfswung. Again, the latter members may be removed to get them out of the way of pieces of work held by the members 9, or the latter may be removed when Athe members 15 are acting in a holding capacity.

With these adaptations the clamp is usable or different forms of work to be glued or otherwise to be attached to one another. Not alone is the tool adapted for gluing purposes since it may be employed where metal parts are to be accurately and lirmly held during soldering or like operations.

In joinery and other work it is very diiiii cult to properly adjust andhold parts being operated upon but with a tool of the nature described an exact adjustment is made possible, since after the separation of the parts of thel adjusted work for gluing they can be brought together in exact positions.

The members 9 vand 15 besides Abeing capable of turning within their vsockets 7 and 13 respectively may be adjusted telescopically within said sockets as may sometimes be desirable.

I claim: y 1. In a ytool of the nature described, the combination with `a pair of arms pivotally connected between their ends, and means to fl (l holdthem in adjusted posit-ions relatively, of a work clamping member carried by each of two corresponding ends of the pair of arms,

the same being adjustable independentlyV named member adjustable relative thereto Vboth in the direction of one another and in a direction Ipa'ralleling the plane of the arms, and adapted also for rotary adjustment, and

l means to fix each second named member in adjusted positions.

2. In a work-holding clamp the combination'with a pair of arms pivotally connected between their ends, and means to lix them in adjusted positions relatively, of a'bifurcated 'member at each of two corresponding extremities of the arms, each provided with a stem, there being a bore in the end of each' `arm extremity, the axes of said bores paralleling the planes of thearms, said bores receiving the stems telescopically, separate clamping means on the arms for engaging the stemsfor fixing the members in adjusted positions, and a clamping screw carried by each bifurcation adapted to clamp a piece of work between the bifurcations and for shiftingthe work in a direction at right angles to the plane of said arms.

3. In a work-holding clamp, the combination with a pair of arms pivotally connected,

and means tohold them in adjusted positions relatively, of a member having a stem to .engage in each of corresponding ends of the arms, there being a socket in each of the latter to receive one of the stems, the latter adaptedfor a telescopic and a rotary adjustment in said sockets, means to fix the stems in adjusted positions, and screws carried by each member adapted to clamp between them a piece ofwork. j

4. In a work-holding clamp, the combination witha pair of arms pivo-tally connected, and means to hold them in adjusted positions relatively, of a member having a stem to engage'in each of corresponding ends of the arms, there being a socket in each of the latter to receive one of the stems, thelatter adapted for a telescopic and a rotary adjustment in said sockets, means to fix the stems in adjusted positions, screws carried lby eachmember adapted to clamp between them a piece of work, there being a bore in eachV member extending in a direction at right angles to its stem, a clamping device having a stem to lie in the bore adapted for telescopic and rotary adjustment therein, and a screw in the member to fix the stem in adjusted positions.

In testimony whereof I aiiix my signature.
