C. A. LIND RIGGER'S VISE Oct. 15, 1929.

Filed May 28, 192B 2 Sheets-Sheet INVENTOR ATTORNEY Patented Get. 15, 1929 stares rarest or-ricE RIGGERS VISE Application filed May 28, 1928.

This invention relates to improvements in Vises and has especial reference to foot clamp riggers Vises.

An object of the present invention is to provide a vise which is especially adapted for use for holding eyes and other fittings while the same are being secured to a rope or cable by a splicing operation, the invention being portable, and thus especially useful in field work and aboard ship.

Another objectof the invention is the provision of a vise which is novel in construction, efiicient in use, and which may be used with or without the foot clamp.

With the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings Figure 1 is an elevation ofa vise constructed in accordance with the invention.

Figure 2 is a top plan view of t 1e same.

Figure 3 is an enlarged section taken longitudinally of the vise, illustrating its use, the section being taken on the line of F igure 2.

Figure 4 is an enlarged section taken on the ine l4l of Figure 1.

Figure 5 is a fragmentary section on the line 55 of Figure 3.

Fi ure 6 is a detail perspective view of one of the clamping aws.

5 Figure '2' is an elevation illustrating the manner of using the vise.

Figure 8 is an elevation at right angles to Figure 7 Referring to the drawings in detail wherein like characters of reference denote corresponding parts, the invention as shown coinprises an elongated frame which is formed of longitudinally disposed parallel side bars 10 and 11 whose ends are connected by transverse members 12.

The side bars 10 and 11 are provided upon their opposed faces with longitudinally disposed grooves 13. These grooves are adapted to receive trunnions 14; which extend from jaws 15, so that these jaws are mounted for Serial No. 381,142.

pivotal and longitudinal sliding movement within the frame.

In order to permit of the insertion and removal of the aws 15, the side bar 11 is interrupted as shown at 16, and this interrupted portion is normally closed by means of a closure member 17. The member 1? is provided with oppositely extending aligned apertured ears 18 which are receivable between apertured ears 19 carried by the bar 11, while bolts or other fastening devices 20 extend through the ears l8 and 19 so as to removably hold the member 17 in place. If desired, one of the bolts 20 may be removed; and the member 17 swung outward as indicated by the dotted lines in Figure 2 of the drawings, so that the jaws 15 may be removed and replaced without entirely removing the member 17.

The opposed aces of the jaws 15 may be and preferably are provided with concavedlm portions 21 to receive an article being gripped,

while the remote faces of the jaws 15 are provided with recesses 22. The recesses 22 receive the inner rounded extremities 23 of clamping screws 2% which extend through and threadedly engage the transverse members 12 at the opposite ends of the frame. The screws 24 are in axial alignment and may be provided with handles or operating members 25, whereby these screws may be conveniently rotated:-

to relatively adjust the jaws 15. Pins 26 extend through the jaws and pass through annular grooves 27 provided at the inner ends of the screws 24.

Extending downwardly from the bars 10 and 11 are spaced parallel legs 28. These legs are connected at their lower ends as at 29 and this connected portion is provided with an internally threaded bore to receive an adjusting screw'SO. The upper end of the screw 30 engages a foot clamp 81 and by means of this screw 30, the clamp 31 may be adjusted with respect to the jaws 15, so as to securely hold an eye or other fitting in place.

The portion 29 which connects the loweres ends of the legs 28 is rotatable within the bore of a split clamp 32 which is carried by a bracket 33 and this bracket is adapted to be clamped to a suitable support by means of an adjustable clamping member 34.

at. rena The vise may be used for holding a thimble in position within the bight of a cable 36, while the latter is being spliced. This use of the invention is illustrated in Figure 3 where in a ring 37 is being attached to the end of the cable. Obviously, the vise may be used for any other purposes for which a riggers vise is adapted.

In order to conveniently hold the cable so that its end may be properly workea, there is provided a bracket 38 which is mounted upon a bench or other support 39, the latter also serving to support the vise. This bracket 38 carries spaced hooks l0 within which the cable is looped.

If desired, the handles or operating members 25 may be omitted and the screws 24: may have their outer ends provided with tool engaging heads 41-.

The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is herein reserved to make such changes as properly fall within the scope of the appended claims.

Having described the invention what is claimed .is

1. A vise comprising an elongated frame including spaced parallel side bars having longitudinally disposed grooves in their opposed faces, a pair of jaws, trunnions extending from opposite sides of the jaws and entering the grooves to support the jaws for pivotal and longitudinal movement within the frame, a removable section for one of the side bars to provide for the insertion and removal of the jaws, axially aligned adjusting screws threadedly engaging opposite ends of and extending into the frame with their inner ends engaging the jaws, means to support the frame, and an adjustable .foot clamp mounted in the frame supporting means.

2. A vise comprising an elongated frame including spaced parallel side bars having longitudinally disposed grooves in their opposed faces, a pair of jaws located within the frame and having recesses in their remote faces, means to mount the jaws for pivotal and longitudinal sliding movement within the frame, axially aligned adjusting screws threadedly engaging opposite ends of and extending into the frame, rounded extremities upon the inner ends of the screws, said round ed extremities extending into and engaging .lhc walls of the jaw sockets whereby the jaws will adjust themselves to the character of-the work, means to support the frame, and an adjustable foot clamp mounted in the frame supporting means.

In testimony whereof I allix my signature.

CHARLES A. LIND.
