M. ZABICH 2,969,817 AXIALLY AND ANGULARLY ADJUSTABLE STRAIGHT BEAM CLAMP Jan. 31, 1961 Original Filed May 31, 1952 IN V EN TOR. M5 177? KKK/6'1? BY W W) United States Patent AXIALLY AND ANGULARLY ADJUSTABLE STRAIGHT BEAM CLAMP Martin Zabich, 1136 Center Ave., Verona, Pa.

Substituted for abandoned application Ser. No. 290,995, May 31, 1952. This application Sept. 28, 1959, Ser. No. 846,528

2 Claims. (Cl. 144297) This invention relates to an adjustable alligator clamp for holding a work piece in connection with gluing or other similar operation. This is a substitute of my application Serial No. 290,995, allowed May 3, 1954, but abandoned by failure to pay the final fee.

The primary object of this invention is to provide a beam clamp which can readily be adjusted to a variety of clamping positions necessary in efficiently handling gluing operations or the like.

The instant device is an improvement over Patent No. 2,581,317 issued to the same inventor. The improvement resides in providing means whereby the movable clamping jaw is restrained from rotary movement about its longitudinal axis when moving axially to a clamping position.

A further improvement and object of the instant device is to provide means whereby the movable clamping jaw and the fixed clamping can be moved bodily laterally relative to their supporting bases so as to be in alignment with variously positioned work pieces.

A still further object and improvement of the instant device is to provide means whereby the elevation of the moving jaw can be varied to suit specifically desired working conditions.

Other objects and structural details will be apparent from the accompanying description, claims and attached drawings wherein Figure l is a perspective view of the device in operative position;

Figure 2 is a sectional view through plane II--II of Figure 1;

Figure 3 is a section taken through plane IIIIII of Figure 2;

Figure 4 is an exploded fragmentary view of the actuating mechanism for the moving clamp.

Referring to the drawings, the moving clamp assembly is adjustably secured to a base plate 11 by the nut and screw units 12 and 13 passing through perforations 15 in a carrier plate 14 and through slots 16 in said base plate. Thus, the plate 14 can be shifted laterally relative to plate 11. Base plate 11 is attached to a bench or the like by means of nuts and bolts in a manner providing access to the operating units 12 and 13. Carrier plate 14 is adjustably secured to a sleeve plate 17 by the adjusting screws 18 and 19, which are threaded in plate 14, and which pass through perforations 20 and 21 in plate 17. Nuts 22, 22a, 23 and 23a, are all threaded to the screws 19 and 18, as shown, for adjusting the position of plate 17 relative to plate 14. Secured to the sleeve plate 17 by the fastening means 24 are the sleeves 25 and 26. Sleeve 25 is internally threaded and receives the actuating stem 27 which is externally threaded and provided with the handle 28. The forward end of the stem has a head 29 connected to the stem by the reduced neck 30 which passes through the bifurcated yoke 31 formed at the rear end of the clamping bar 32. Clamping bar 32 is cylindrical in form and is received in the internal bore of the sleeve 26, and comprises the medial cylindrical portion 33 formed with the guide grooves 34, the forward jaw portion 35, and the aforementioned rear yoke member 31. Sleeve 26 comprises the internal bore, the enlarged rear bore 36 to facilitate making the connection between the yoke 31 and the head 29, and the supporting legs 37 and 38 through which pass the fastening means 24. Passing through the boss 39 formed on the sleeve 26 is the guide screw 27a which coacts with the grooves 34 to prevent rotation of the clamping jaw 35 when moving forward.

The fixed jaw 40 is carried by the support 41 which is fitted with the holes 42 variously located, whereby both vertical and horizontal positions of the fixed jaw can be selected.

An offset tongue portion 43 extends from the support 41 and is provided with the flat connecting plate 44 having the slot 45 which is aligned with the slot 46 formed in the base plate 47. Plate 44 can be adjustably secured to the base plate 47 by the nut and screw assemblies 48 and 49, base plate 47 is secured to a work bench in any conventional manner, leaving space for 43 and the actuation of bolts 48 and 49.

In operation the fixed jaw 40 is placed in one of the holes 42 and the moving jaw 35 is rotated to align with the selected position of 40. The selected adjustment is retained by means of the screw 27a in conjunction with one of the slots 34. By means of the screws 18 and 19 the elevation of jaw 35 can be adjusted as desired. Both fixed and movable jaws can then be shifted laterally to align with the position of the work piece by means of th adjustable connections to the base plates 11 and 47. By rotating stem 27, jaw 35 is moved axially to a clamping position relative to jaw 40.

It is apparent that the above disclosed device is a suflicient departure and improvement over the preceding patent (2,581,317) and the prior art to warrant a patent grant. A greater degree of adjustability and flexibility to meet varied working conditions has been achieved in the current device while adhering to the demands of simplicity of construction and low fabrication costs.

It should be understood that changes in size, shape and material, all be within the inventive scope.

Having thus set forth and disclosed the nature of this invention, what is claimed is:

1. A clamping device comprising a fixed jaw having a support provided with a plurality of holes in two transverse planes, said jaw being connected to the support by a projection fitting into the holes in a snug fashion, said support having a slotted connecting plate and a separable slotted base plate, fastening means extending through said slots whereby the connecting plate and the base plate can be adjustably connected, in combination with a moving jaw having a cylindrical body with longitudinal grooves slidingly received in a sleeve and having an adjustable guide screw projecting selectively into one of said grooves, said sleeve being connected to a support plate which is connected to a carrier plate by means of a plurality of adjusting screws threaded in the carrier plate and passing through perforations in the sleeve supporting plate, said screws carrying positioning nuts between the carrier plate and the support plate, whereby the spacing of the carrier plate can be adjusted relative to the support plate, the carrier plate being mounted on a slotted base plate by means of bolts passing through said slots and through perforations in the carrier plate whereby the two last said plates are transversely adjustable, the moving jaw being rotatable within the sleeve and having forwardly extending teeth whereby the teeth may be selectively positioned to oppose the fixed jaw in any of its planes, a second sleeve internally threaded, secured to 3 the sii'pp'or't plate, "ath'readedstem extending through the 'Sbcdh'd sleeve, *8.
