My invention relates toimprovements; in means for clamping .parts'inzposition lZO'ftlCllltate the securementor workingthereof, such as in the art of woodworking, and the same has for its .objectto provide a simple etficient and reliable device-which-is readily manipue lated andsecuredinposition to exert a'clamping action alonga plurality. of {lines of direction, or at a pluralityxof points.
Another object of the invention is to prowhich certain ofthe clamping components thereof are capable o=fvbeing relatively moved to exert conjoint'ly 1a third z-clampingfaetion along a -line of directioncextending trane versely relative to the lines of direction of said claimping componehts- Another object of the invention is "to provide'a device of/t'he character specified in nectedrto apair ofordinary clamps 'forcausing positive movement thereof towards :each

:Fig. 2 :is an.elevationithereofihv. Fig. 3 is a view showing amodifiedrform of supplemental clamping component; {and i Fig. 'is 'a detail viewpartly in section! 7 Referring to the drawing the clamping.
means includes a pair iofprdinary clamps l0 and 12, each comprising a standard 14 having a 'lower'iarm- 16 secured thereoirand upperarm 18 slidable thereon. The outer end of lower arm 16'is provided with a'universally swiveled abutment member 20 adapted to engage a 'p'ieceor member 110' be which. an attachment may beg-readily con.- 7
clamped and the outer'end of theupper arm 18 is provided with a screw 22 threaded therethrough and having a universally swiveled abutment 24 cooperating with the abutment 20. stant-ially alike in construction The clamps l0 and 12'are connected together by means 28 for moving the clamps towards each other to conjointly exert a clamping action along a transverse line. The connecting means 26 includes a pair of arms 28 and 30pr'eferably providedwithhook-like or slotted end portions-'32'and 34; adapted toembrace the standards 14 to extend laterally towards each other and secured to the stand-. ards by the set 'screws 36. The means 26 may be adjusted along and secured to -the standards at various points relative to the work sothat the workdoes not interfere with the operation of the device. The member 30 is pivoted at 38 intermediate the ends thereof to the member 28 near the outer end of the latter, and extends transversely of the member 28 and rearwardly beyond the same.
The outer end oithe arm or'member 30 carries aunutfeO swiveled on the pivot 42. A clamping screw 44: passing through and cooperating with the nut vtO is connected at the outer end 46 thereof to the arm 28 contiguous to the-inner end thereof, said end 46 being rotatably retainedin the swiveled meniber LS pivoted at50 on arm 28. p
Supplementary -or au'xiliary clamping is. also obtained clamping component 52 constituting an attachment which may be secured-to either standard llby means of the nutfie' havinga slot 56 adapted to engage ;-the standard 14, andsecured thereto 'by a screw v58. 1 clamping screw 60 passes through thewnut54 and is, provided with V jaruniversally: movable abutment 62 at the outer "end ithereo'f. The clamping )means 52 The two'clamps 10 and 12- are. subprovides the fourth clampingcomponent and v exertsraiclamping action along a line extendlng transversely oft-he'li'nes of clamping actionpo'f the other three clamping comb0nent i.",
,As shownat 3 'the' fourth clamping i component- 52 may include a nut portiont l having a standard engaging slot 56 extendi ing parallel with the threaded opening 66 and a standard engaging slot 68 extending at an angle to the opening 66. By securing the means 52 to either standard 14 through slot 68, the clamping action is exerted at an incli nation relative to the work. Bysecuring the means 52'? to the standard through slot 58 the clampingaction is exerted normally relative to the work. c
In operation, theactuating means 26 are readily secured to the clamping components 10 and 12 by engaging the slotted portions 32 and 34 with the standards it and securing the same by set screws 3- 1.; Theclamping compohentslO and 12 are then engaged with the work, such as, for example, the pieces or members A and B, by adjustment of the screws 22. By rota-ting thescrew M the clamping components 10 and v 12 movetowards each other to exert a third clamping action along a transverse line and cause the pieces or members A and B to 'be firmly pressed into engagement'with each'other at the contiguous edges C thereof. I
In my invention the clamping components 10 and 12 therefore-form conjointly a. third clamping component, thereby rendering the device more universal and flexible and enlarging the usefulness thereof. l/Vhen remay be secured in position on either standard 14 and the screw 44 thereof adjusted toclamp the member or piece D to retain the same in engagement with the pieces A and B. Then it is necessary to operate the fourth. clamping component at an angle, for example, as shown at Fig. 3, as when an angular piece E is employed, the component 52 is employed and secured to the standard 14: through inclined slot68. 1 a
My device may be readily manipulated and secured in position, and provides three or four different clampings as required. The working or securementof, the pieces-is there by-greatly facilitated and the device may be employed; in connection with types of work forwhich the individual clamps 10sor 12 are inadequate, thereby providing a device having an enlarged range of usefulness, and particularly in connection with the fabrication of veneered articles; or in connection with working u on curved surfaces.
