Specification of Letterslfatent. Patented Sept. 19, 1918.
Application filed. October 7, 1916. Serial No. 124,277.
To all whomit may concern .3
Be it known that I, GUsTAv State of New York, have invented-certain new and useful Improvements in W'ork- Clamps, of, which the following is a specifi- -The present invention relates to work clamps and more particularly to the type designed for holding small articles which are round Or otherwise irregular in cross section, anobject of this invention being to provide a reversible movable for bold-- ing articles of diiferent'diameters, thejaw being so arranged that it is symmetrical with reference to the rest of the clamp and:
does not project beyond the lines of the remaining portions, whereby the clamp mayv be readily held in a vise to exert equal pressure upon the fixed andthe movable jaw of the clamp. H
. To this and other ends, the invention con-.. sists of' certain parts and combinations of parts i all of 'which 1 will be hereinafter described, the novel features being pointed out in the appended claims.
In the drawings L- s Figure l is a perspective view of a work clamp constructed in accordance with the present invention;
Fig. 2 is a view partly in longitudinal section through the clamp, the clamp being adjusted for removing a taper pin; and
Fig. 3 is a transverse section on the line 33, Fig. 1.
Referring more particularly to the drawing, 1 indicates the shank which has lateral extensions 2 and 3 at opposite ends, both projecting in the same direction. The projection 2 serves as the fixed jaw of the clamp while the projection 3 serves as a support for an operating screw 4: which extends through the projection 3 and has a hand piece 5 at one end and a cylindrical portion 6 at the other end. The two extensions are equal in height and are of the same width as the shank 1.
Between the extensions 2 and 3, the shank 1 is formed with a guideway preferably provided by grooving the shank 1 at 7 on opposite sides. On this guideway a movable jaw 8 operates, said jaw also having a guideway formed preferably by two parallel ribs or lugs 9. Opposite faces of this jaw 8 are pr vided with p k ts l0 a ap ed-to receive A. BABE-R, CItIZBII'Of thG'UIlltGCl States, and resident'off Rochester, in the county of Monroe andl thecylindrical end of the operating screw.
4 so as to. hold the. movable jaw; 8 tothe shank while, at the same time, permitting the screw to force the movable aw 8 toward the fixed jaw 2. This movable-jaw has; two.
clamping faces 11 and 12, each of which may be provided with crossed or intersecting grooves 13, thegrooves on oneside being deeper. than the grooves on the other side so as-to hold objects of difierent sizes. The purpose of having the crossing. groovein each clamping face is to hold the object either. perpendicularly to or parallelwith the shank ofthe clamp. The pockets 10 are arranged at the points of intersectionba' tween the grooves so that thepressure isapplied in the plane of the object whether it be arrangedin one groove or the other. height of the movable jaw and the width thereof, transversely of the shank, are both substantially coextensive, respectively, withthe height and width of each ofthe two extensions so'that, when the clamp as a whole is placed in the vise, equal pressure will be exerted upon the two extensions and; the movable jaw, thereby preventing any rocking motion of the work clamp and the vise.
Either clampingv face of the jaw may be made effective merely by disengaging the movable from the operating screw and turning the jaw 180 degrees, the guideway on the jaw cooperating on the guideway on. the shank in both positions. 7
If desirable, the fixed or stationary jaw 2 may have a pocket 14 formed therein for the reception of a pin 15 which will engage one end of a taper pin 16 in order to drive said pin from an object 17, the pocket 10, in this instance, providing a recess in which the pin may enter as it is driven from the object 17 A work clamp constructed in accordance with this invention provides a simple and inexpensive construction which may be quickly adjusted to present either of two clamping faces on a movable jaw to operative position. Each of these clamping faces is so formed that it may hold objects perpendicularly to or at right angles to the The shank of the clamp. The guideways be-v What I claim as my invention and desire to secure by Letters Patent is I c I 1. A work clamp comprising a shank having lateral extensions at opposite ends, one
of said extensions serving as a fixed jaw, an
operating screw mounted on the other extension, and a reversible movable jaw guided on the shank and having opposite faces formed with pockets for receiving an end of, the screw.
2. A work clamp comprising a shank having laterally-turned extensions at opposite ends and guide grooves along opposite sides of the shank between the extensions, the surface of the shank between the grooves beingcontinuous to provide a support for the work and one of said extensions serving as a fixed jaw, an operating member mounted on the other extenslon, and a reverslble movable jaw having depending ribs operatmg insa1d gu1de grooves and having also a width and a length co-extenswe, respectively, with the width anclthe length of each of the two-extensions, the ribs being so formed'that thejaw may be removed laterally from the'guidc grooves, and the operating member and an opposite face of the movable jaw'ha'ving cooperating portions permitting the movable jaw to have either face thereof interlocked with the operating member to hold the "jaw to the guides;
3. A work clamp comprising a shank having laterally turned extensions at opposite ends and grooves along opposite sides, one of said extensions serving as a 'fixed jaw, an operating screw mounted in the other extension, and a reversible jaw having a pair of depending ribs operating Copies of this patent may be obtained for in said grooves for either position of the aw and also having pockets in opposite 'faces'for receiving" an end of the serewto hold the movable jaw to the shank, the ribs being so formed that the jaw may be re-' with the guidewayon the shank for eitherposition of the jaw, said reversible jaw having pockets inits'two clamping faces for receiving an'end of the screw to hold the movable jaw to the shank, the jaw being removable laterally of the guideway when the operating' screw is disengaged "fron'r such jaw. V
'5. A work clamp comprising a shank having laterally turned extensions at opposite ends and a'guidew'ay between the extensions, one of said extensions serving as a fixed jaw and having an opening therein,
an operating screw mounted onthe other extenslon, a jaw movable on the guid'eway and having two intersecting groovesin a clamping face thereof, and also having an opening at the point of such intersection, the jaw being, engaged by the operating screw, and a pin engaged within the openg ing of the'fixed jaw andprojecting therefrom in line with the opening in the movable jaw. r v
