Haddad, 14 Oxford St., Worcester, Mass. Original application Apr. 3, 1961, Ser. No. 160,403, now Patent No. 3,124,347, dated Mar. 10, 1964. Divided and this application Sept. 11, 1963, Ser. No. 318,772

3 Claims. (Cl. 81-367) This application is a division of my prior application Serial No. 100,403 filed April 3, 1961, now Patent No. 3,124,347 and relates to improvements in quick-acting vice grips, and the principal object of the invention re sides in the provision of attachments to and modifications of parts of adjustable toggle plier type wrenches to render the same much more versatile in use and application, with particular emphasis applied to the problem of quickly clamping a succession of pieces to a worktable such as for instance with drill presses, for engravers, and for anyone who must work on pieces which must be clamped to a worktable or bench.

Other objects of the invention include the provision of a new and improved vice grip having a single jaw and including means by which it may be utilized as a holddown device at the edge of a working surface as for instance by the application of a C-clamp or similar clamp; the provision of means whereby the tool may be used as a hold-down or grip within the confines of the working surface of the worktable by the application of a fastener such a bolt inserted through a hole in the table and held by a nut or in conjunction with the usual T-slot as on a milling machine table; the provision of a special new and improved removable jaw in addition to and for cooperation with the said single jaw, such removable jaw taking the place of the conventional lower jaw of the tool when the device is not to be used as a hold-down on a table but is to be used in the normal manner.

The invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly set forth in the appended claims.

Reference is to be had to the accompanying drawings, in which:

FIG. 1 is a view in side elevation, part being in section, illustrating the invention as applied to a worktable',

FIG. 2 is a view looking in the direction of arrow 2 in FIG. 1 with part in section;

FIG. 3 illustrates an extension means for the upper J FIG. 4 illustrates the removable lower jaw in position;

FIG. 5 is a view in elevation of the new and improved removable lower jaw;

FIG. 6 is a view in side elevation illustrating an alternative form of extension for the upper jaw;

FIG. 7 is a view looking in the direction of arrow 7 in FIG. 6;

FIG. 8 is a view of a modification for use as a holddown with magnetic chucks;

FIG. 9 is a view in elevation looking in the direction ofarrow 9 in FIG. 8;

FIG. 10 is a side elevation of a supplementary jaw, and

FIG. 11 is a top plan view thereof.

This invention contemplates basically the use of an adjustable clamping toggle type of plier or wrench as for instance shown in RS. Patent No. 2,514,103 and other patents. This tool is well known in the art.

Referring now to FIG. 1, the lower jaw member of the wrench has been removed but the upper jaw at 10 is the same as in the well known type of adjustable Wrench referred to, and is actuated as for instance by a handle orlever 12 having arelease lever 14, the adjustment handle orlever 16 having the well knownscrew 18 by which thejaw 10 is adjusted with relation to the now removed lower jaw.

Thelever 16 extends forwardly into a bifurcated relation comprising a pair ofside plates 20, these being spaced apart and connected by alower web 21 portion also as well known.

These walls are cut away in this invention at theweb 21, leaving an elongatedrectangular aperture 22 at the web part of themember 16 adjacent the forward end thereof, and this leaves a web portion at 24 extending betweenplates 20, 20, this web portion terminating as for instance in a relativelysharpened edge 26 from which extends an opening or slot betweenplates 20, 20 to ac commodate the wrench jaws.law 10 is pivoted to theplates 20, 20 as for instance on thepin 28.

There is provided an eye-bolt or the like generally indicated at 30. It has an eye at 32 and is pivoted between the twoplates 20, 20 at 34. It extends through the opening 22 and may extend therefrom through a hole or the like 36 in aworktable 38. Anut 40 is provided and this nut is shown in FIG. 2 preferably as in the form of a T, by which means it may be utilized with respect to the usual T slots found in a milling machine table. In the form of the invention illustrated in FIG. 1, the eyebolt is shown as bent slightly in order to accommodate itself to a pivot point at 34 and still leave theweb part 24 for a purpose to be hereinafter described.

Also in order to maintain thepart 16 in a more or less parallel relationship with respect to the top surface of the table 38, there is provided aplate 42 which is apertured to receivebole 30 and at its rear end has anupstanding flange 44 which may be cut away centrally thereof so as to accommodate thepart 16 as in a cradle.

The entire device may be pivoted about thepivot 34 if desired but in any event it will be seen that after adjustment by screw 18 parts on the table may be quickly and very conveniently clamped and unclamped thereto by means of thejaw 10.

As shown in FIG. 3, a block of any size, shape or extent which is indicated by thereference numeral 50 may be pivoted as for instance at 52 to theside plates 20. Themember 50 may be bifurcated as illustrated at 54 and is actuated by thejaw 10, to clamp a piece to the table at a point remote fromjaw 10.

Thepivot 52 may be located where desired to increase or decrease leverage. Ifblock 50 should be made of wood, it can be provided with holes to admit tools such as drills. Also (see FIGS. 10 and 11), this block may be made of sheet metal and bent to bifurcated shape, havingprojections 51 to accommodate a tool therebetween, and alignedholes 53 to accommodatepin 52, on rearwardly extendinglegs 55.

Another form of such an extension is illustrated in FIG. 6 wherein there is shown a C-clamp 56 which may project through the opening at 22 and forwardly between theplates 20, 20 so that the entire device may be clamped to the edge of a table which is indicated at 58 rather than within the table top area through theaperture 36 as shown in FIG. 1. The C-clarnp may bear onpart 24 and on thepivot part 59 ofjaw 10 if desired, to better hold the clamp in place.

Thejaw 10 in FIG. 6 may be provided with a quicklyremovable extension member 60 which may or may not have a downwardly turnedflange 62 at the remote end thereof and in any event it has .an apertured upwardly extendingflange 64 which slips in the direction of thearrow 66 onto thejaw 10. The aperture in theflange 64 is shown at 68 in FIG. 7 and is shaped to accommodate thejaw 10. There are also a pair ofspurs 70, 70, one at each side of the jaw member so as to hold the extension in position as will be clear to those skilled in the art.

FIGS. 4 and 5 illustrate the removable lower jaw member which is a single solid fiat piece having a clamping ing the parts in the position shown.

edge at 72 and at the opposite edge thereof a rearwardly extending relativelysharp spur 74.Adjacent spur 74 at 78 which is relatively elongated. The removable jaw terminates rearwardly in anotherspur 80. These spurs are not always necessary and could be dispensed with if desired.

Referring to FIG. 4 it will be seen how this member is held removably in position with respect to the spacedplates 20, 20. The removable jaw isthrust spur 80 foremost through the front slot between theplates 20, 20, this being seen in FIG. 2. Thespur 74 is accommodated at thesharp portion 26 of theweb 24 and theelongated projection 78 extends down through the opening at 22, hold- In this form of the invention the device is'used in the ordinary manner which is clear to those skilled in the art but if the removable jaw is desired to be separated, it is merely necessary to tap it in the region of the member at 74, 78, thus loosening it from its position as held in thewrench member 20, 20. It will be observed that the inner rounded end of jaw indicated at 82 bears on the upper surface of the removable jaw near thespur 80 and aids in holding the same in the operative position shown.

Furthermore if the device is desired to be utilized to hold articles down to a magnetic chuck or the like, a steel base indicated at 84 may be utilized with apivot pin 86 pivoting the entire Wrench in position by means of thelower member 88 to which the upper jaw at 90 is attached in the conventional manner, the rest of the wrench being the same but with of course the lower jaw removed as before.
