300 | TOOL JAW(S) POSITIONED BY RELATIVELY MOVABLE PLURAL HANDLES (E.G., PLIERS): | ||||||||||||||||||||||||||||||||||||||||||
This subclass is indented under the class definition. Tools including at least two relatively movable work-engaging
elements (constituting jaws), at least two relatively movable hand-gripped
elements (constituting handles), and joint mechanism interconnecting
said jaws and said handles whereby manipulative movement of the
handles with respect to each other effects relative movement of
the jaws.

| GLOSSARY | |||||||||||||||||||||||||||||||||||||||||||
| ACTUATION | |||||||||||||||||||||||||||||||||||||||||||
|
The manipulation of handles relative to each other, so as to move jaws to engage work, within the limits of a predetermined range of jaw movement. (See the definition of "RANGE" hereunder). | |||||||||||||||||||||||||||||||||||||||||||
| ADJUSTMENT | |||||||||||||||||||||||||||||||||||||||||||
|
The changing of structural relationships between members constituting the tool so as to vary the limits of jaw movement from one predetermined range to another. (See the definition of "RANGE" hereunder). | |||||||||||||||||||||||||||||||||||||||||||
| HANDLE-MEMBER | |||||||||||||||||||||||||||||||||||||||||||
|
A member which is gripped by the hand of the operator to which member one of the jaws is fixedly attached at least during the actuation of the jaws. | |||||||||||||||||||||||||||||||||||||||||||
| HANDLE-LEVER (OR GRIP-LEVER) | |||||||||||||||||||||||||||||||||||||||||||
|
A hand-gripped element connected to a handle-member and to a movable jaw as by pivot, link or motion-converting means, which hand-gripped element actuates the movable jaw. | |||||||||||||||||||||||||||||||||||||||||||
| HANDLE | |||||||||||||||||||||||||||||||||||||||||||
|
The generic term for either a handle-member or a handle-lever where no distinction between the two members is necessary. | |||||||||||||||||||||||||||||||||||||||||||
| JAW | |||||||||||||||||||||||||||||||||||||||||||
|
An element carrying at least one work engaging surface, two or more of such elements engaging and holding the workpiece. | |||||||||||||||||||||||||||||||||||||||||||
| JOINT MECHANISM | |||||||||||||||||||||||||||||||||||||||||||
|
First means connecting the jaws movably to each other, second means for connecting at least one of the jaws movably to the handles, and third means connecting the handles movably to each other; said first, second and third means (either singly or in combination with each other) converting handle manipulation into relative jaw motion. The joint mechanism may consist, for example, of a common first, second and third means as for example in Patent No. 2,325,035; or a common second and third means as for example in a pair of cross-handled pliers. | |||||||||||||||||||||||||||||||||||||||||||
| RANGE | |||||||||||||||||||||||||||||||||||||||||||
|
The extent of movement of the jaws relative to each other, unobstructed by the work to be engaged or by contact of the jaw surfaces, which movement is effected by manipulation of the handles from one extreme position of the handles to the other extreme position of the handles relative to each other. The range is predetermined by the structural relationships between the elements constituting the tool. To illustrate: assuming that the movement of the handles between extremes of handle positions effects a jaw movement of one inch, the one inch dimension equals the range, which range is the same even though the device may be adjusted so that in one instance the jaws move from a zero gap position (closed) to a one inch gap or in another instance from a one-half inch gap to an inch-and-one-half gap. The shift described is defined as adjustment; the manipulation of the handles to effect the one inch of jaw movement is defined as actuation. | |||||||||||||||||||||||||||||||||||||||||||
| TOGGLE JOINT OR TOGGLE | |||||||||||||||||||||||||||||||||||||||||||
|
A linkage including at least two links, pitmans, bars or struts, and at least three pivots, the end of one link being connected to the end of the other link by a pivot common to both links, each of said links also having a pivot at the end remote from the common pivot, which common pivot or intermediate pivot is movable from a position not in a straight line with the other two pivots, to a position substantially in line by a force applied to the intermediate pivot in a direction substantially normal to one of the links thereby moving at least one of the two pivots away from the other. At least one of said links is articulated at both ends and is not integral with either a jaw or a handle. The intermediate pivot is on the handle-lever or is connected to the handle-lever by a linkage or lever system between said intermediate pivot and the handle-lever, so that force is applied to the intermediate pivot by manipulation of the handle-lever. | |||||||||||||||||||||||||||||||||||||||||||
