No. 809,882. Specification of Letters Patent.
Application filed mi m 31, 1905. Serial No. 276.609..
Be it known that I, JOHN WRIGLEY, a citizen of the United States, residing at Philadelphia, county of Philadelphia and State of Pennsylvania, have invented a newand use- Improvementin Clam s, of which the following is a full,'clear, an exact description, reference bein had to the accompanying drawings, whic fornna part of this specification. Y
My inventionorelates to clamps, and has for its object to provide a construction by which work of the same thickness may be clamped with a definite pressure a number of times or at a number of positions with-the- Figure 1 is a side eleva- In the drawings,
Fig. 2 18 a section on the tion of the clamp. line2 2 of Fig. 1.
a is a yoke carrying at the end of its lower arm a handle I), pivoted to the yoke at c. To the connecting member of the yoke a. is pivoted a lever d, having the clamping-jaw e.
f is a link connecting the end of lever (1, carangle-irons.
the clampingfiaw j to the desired osition, whereupon t e latch is released an springs intIo the groove 2'. in alinement therewith.
the clamp is applied, although it will be un derstood that it is capablof application to many other uses.
1 It is necessary in structural work to mark on the angle-irons the position of the boltholes. There are often'quite a numberof such angle-irons, have a like arrangement. For this purpose a wooden templet is provided having holes arranged in a manner correspondin to the desired arrangement of holes in eac of the The wooden templet and an angle-iron are clamped between the two jaws of a clamp, and the proper positions of the holes may then be marked on the an leiron. The templet and angle-ironare t en released and another angl'e-nonsubstituted. This operation may be repeated a number of times,
rymg the jaw c, with the end of handle I) adjoining its pivot c.
A screw 9 extends through a threaded nut 71. on the upper end of the yoke.v The lower end of the screw is cb nnected by a ball-andsocket joint with the other jaw j of the, clam The upper end of the screw has a whee 'i, by which the 'screw may be turned. The screw g is provided with a pluralityof grooves '5, extending longitudinally of the screw.
7c isa spring-latch secured to the top face of the up er arm of the yoke and extendin downwar ly within a slot m in the nut and thince, outwardly below the upper arm of the yo e.
n is a projection secured to the downly-extending arm of the latch. The slot m is located adjacent to screw g, and when the screw is turned to bring one of its grooves '21 into alinement with the slot m the projection n on thelatch 1c springs into the groove and holds the screw in its adjusted position. To permit the screw to' be adjusted, the free end of the latch is pressed against the lower face of the upper arm of the yoke, projection 12. from the screw-groove, and the etch is held in its clamping and unclamping the work may be ap reciated.
to the position shown in full lines in Fig.1 an the templet and the first angle-iron placed in position. The screw 9 is then adjusted until the jaw y' is brought firnily against. the templet and the templet and angle-iron clamped with the requisite pressurebetween the jaws of the clamp. The latch 7c is then'released, permitting the projection n to snap into one of the grooves i of the screw. When the first angle-iron is properly marked, the handle I) is moved to the position illustrated in ,dotted lines in Fig. 1, and the templet and angle-iron are then removed. The templet and another angle-iron are then inserted and the handle returned to the full-line position shown in Fig. 1. It will be understood that the construction is such that each time that the handle is returned to its 0 erative position the jaw e is brought to a defiiiite and unvarying distance from the jaw i so long as the screw is held in 'its adjusted position. Therefore at such clamping operations the templet and angleiron will be clamped together with precisely the requisite pressure, no readjustment being retracted position until the screw 9 adjusts together a toggle-joint, its movement to- Patented Jan. 9, 1906.

in all of which the holes noperating my clamp {the handle is swung will now describe one of the uses to which from which the importance of quickly lever handle ward the clam ing position being by the joint d of t e toggle engaging a lug a near the end of the lower arm 0 t yoke.
. Ha now fully described my invention, what I c aim, and desire to protect by Letters Patent, isy 1. In a clamp, the combination, with an adjustable clampin -jaw, of a-second clamping-jaw, a ivoted ever'carrying the second jaw, a ban le-lever and a link comiectin one end of the handlelever with the secon clam ing-jaw.
2. In a clamp, the com ination withthe yoke, of an adjusting-screw at one end there-. of, a clamping-jaw movable by said screw, a i oted to the yoke, a clamping-j aw .carri 'by the lever, a toggle between the second jaw and the other end of the yoke, and means to operate the toggle. I
3. In a clamp, the combination with the yoke, of an adjusting-screw at one end thereof, a clamping-jaw movable by said screw, a lever ivoted to the yoke, a clamping-j aw carrie by said lever, a handle pivoted near its end to the other end of the yoke, and a link connecting the end of the handle the clam ingaw lever.
4. a clamp, the combination yoke, of a clampin the yoke, a lever pivoted on the yoke, a sec ond clamping-jaw carried bysaid lever, a
ivoted on. the other end of the with the yoke, and a k connecting the handle an the pivoted near one clam ing jawle'ver.
5. a clamp, the combination, with the yoke, of a clamping-j aw carried at one end of the yoke, .a secon clam ing-'aw, a handle end at t eot er end oi the yoke, a link connecting the end of said handle and the second clamping-j aw, a pivoted lever connecting the second aw and yoke, and a lug onthe handle limiting the movement of the to gle.

of,-. a clamping-jlaw carried at the end of the screw, a spnngatch on the yoke adapted to engage a groove in the screw to hold the latter to its adjusted position, a second clamplugaw, an clampmgjaw with the yoke, adapted to move the second clamping-aw toward the first clampmg-jaw into a efinite position W1th respect to the oke,
7. In a clamp, t e combination with the of, a clamping-jaw carried at the end of the screw, a springetch-on the yoke adapted to engage a groove in the screw to hold the latter to its adjusted position, a lever pivoted on the yoke, a second clamping-jaw carried by said lever, a handle ivoted at the other end of the yoke, and a ink connecting said handle and clamping-jaw lever.
8. In a clam the combination with the yoke of a threa. ed nut at one end thereof, an adjiis ting-screw, having longitudinal grooves working in said nut, a clamping-jaw jointe to the end of said' screw, a spring-latch extending into a slot in the nut, a projection on said latch adapted to engage either of said out said slot whereby the latch ma be operated to retract said projection, a ever pivoted to said yoke, a second clamping-jaw on the free end of said lever, a. handle. pivoted near one end to the other end of the yoke, a link connecting said clam ing-' 'handle end, and a lug on t e yo e ada ted to engage the joint between said link and andle when the latter is operated to move the sec-'' ond jaw to clamping position.
