(Cl. 8l-46) 12 Claims.

a hand gripping the pliers, so that the Y other hand oi' a person using the tool may be entirely free to manipulate work.

Another object is to adapt either end of one handle of a pair of pliers to rock to or from the other handle and to provide for opening or closing the plier jaws accordingly as pressure is applied to one or the other end of the rocking handle.

A'urther object is to provide for actuation of the jaws of pliers through a pair of toggle links adapted to lock the jaws in engagement with work.

These and various other objects the invention attains by the construction hereinafter described and illustrated in the accompanying drawings, wherein:

Fig. l is a side elevational View of the pliers, 'with their jaws open.

Fig. 2 is a similar view with the jaws closed.

Fig, 3 is a top plan view of the tool.

Fig, e is a cross sectional view taken upon the line ll-i of Fig. 2.

Fig. 5 is a fragmentary section taken on the line d l of Fig, 2, showing'particularly the lower jaw.

Fig. 6 is a side elevational view of the pliers in a modined iorm.

T"i if is a cross section taken on the line 'l--ll in these views, the reference characters l and i designate the paired elongated handles of my improved pliers, each preferably formed of sheet metal bent to a U or channel cross section, the id portion of the handle 2 being integrally formed with a pair of spaced, opposed lugs 3 projecting into the channel of the handle l and terminally pivoted on the latter by a rivet il or the like. Rigidly and integrally projecting from the handle l and preferably aligned therewith is a conforming to the U cross section of said handle, and a companion jaw 6 is pivoted by a rivet or the like i on a support 8 transversely and integrally projecting from the handle i at its juncture with the jaw 5. The support B is hollow, comprising spaced parallel portions similarly extending from the sides of the handle l and jointly forming a wall 9 at the iront ofsaid support. The iree end portion of said support is forwardly bent to receive the pivot rivet l. The

jaw li is formed of standard bar material, its major transverse axis being inthe plane jointly established by the paired jaws, except as regards the front portion of said jaw, the bar having a ninety degree twist to render the major axis of its front portion transverse to said plane.

Housed within the hollow support 8 is a pair of toggle links lll and il forming anactuating connection for the jaw 6, said links when aligned being substantially transverse to the jaws. The link it is dual, engaging at`each side of the rear end of the jaw S and being pivoted to the latter by a pin i2. The link Il which is preferably single is at one end connected to the link it by a pin 12a and has its other end pivoted on a rivet or the like i3 disposed at the juncture of the handle l, jaw 5, and support A link bar it forms a swinging actuating connection from the handle 2 to the toggle links, lthe rear end of said bar extending into the channel of said handle, and engaging a rivet l5 at the base of the lugs 3, and the front end of said bar being pivoted to the pin i261.

At their forward ends, the jaws 5 and E carry work clamps which may be constructed to suit the particular purpose of the pliers. The clamps illustrated are formed by bolts I6 engaged in oversized openings in the jaws and each rigidly secured to its jaw by a pair of lock nuts il, Said clamps project toward each other a distance reg' ulable by the lock nuts, and their adjacent ends any desired shape. Preferably the free end of the jaw 5 is so conformed to the inner lock nut associated with such jaw as to restrain such nut from rotation.

The modication illustrated by Fig. 6, conforms to the preceding description as regards the handles l' and 2', the lugs 3', the jaw il', the support S', toggle links Hl' and il', link bar ifi', and clamping elements l5. In place o the nonplvotal jaw 5, however, the jaw ii is duplicated, the handle l having a slight forward extension it beyond the support 8' to pivotally mount the second jaw 6, and the toggle link il being pivoted to the rear end of said second jaw. in this construction, both toggle links I t and il are dual and the pin 2i interconnecting said links has projecting ends guided in channels 22 formed by the opposed walls of the support 8' and extending parallel to the handle l.

In either form f the described tool, the jaws may be closed or opened, accordingly as the forward or rearward end portion of the handle 2 vor 2 is pressed toward the handle l or i. Thus-by merely shifting the hand gripping the tool a few.

inches forwardly or back, the'response of the jaws to an applied gripping force may be ref fact that the toggle links are adapted, in closing the jaws on work, to swing slightly beyond a dead center position, as clearly appears in Fig. 2, so as to eiect a locking of the jawsin engagement with the work. Movement of said links beyond dead center is of course slight, being limited by engagement of the front end of the bar I4 with the wall 9. Opening travel of the jaws 6 or 6' is limited by inclined upper portion of the wall 9.

An important distinction is to be noted between my improved gripping tool and those lacking a locking effect. In absence of a locking action, the work is freed on relief of the muscular effort applied to maintain gripping action of the jaws. In the tool now disclosed, upon snapping4 of the toggle links beyond their dead center position as illustrated by Fig. 2, there is set up a powerful resistance to separation of the jaws. Release of the jaws involves the application of a force adequate to shift the toggle links past dead center. 'Iherefore, the handle leverage requisite for release of the jaws must be substantially equal to that provided for closing the jaws. i

Limitation of opening travel of the jaws is vital in the disclosed construction since in absence of such limitation, the pin I2 might be shifted downwardly across the dead center line established jointly by the pin I2a and rivet 1, thus reversing the intended control exercised by lthe handle on the jaw 6. f

Said pliers have numerous uses and are particularly suited for production jobs, in which a certain operation requires constant repetition, one adjustment of the work clamps serving for all such operations. The pliers are further well suited to use as a C clamp and for holding parts in intimate contact during welding or other operations.

The invention is presented as including all Y stantially transverse,

such mocliiications and changes as come within the scope of the following claims.

What I claim is:

i. A pair of pliers comprising a pair of elongated coacting handles, a pair of spaced coacting jaws mounted on one of said handles, the mounting of at least one of said jaws being pivotal,

means pivoting the mid portion of the other handle on the jaw-mounting handle, a, pair of toggle links interconnecting the jaws and eiectivevto close or open the jaws accordingly as said links are shifted to or from alignment, and a link bar forming a swinging actuating connection from the mid portion of the pivotal handle to the juncture of the toggle links, whereby the jaws are opened or closed accordingly as one or the other end of the pivotal handle is rocked toward the companion handle.
