Abstract
Clamping pliers includes a first handle with a first jaw, a second handle, a separate second jaw all of which are pivotally connected to a pivot to affect pivoting about the same pivot point. A connecting link connects the second jaw with camways defined in the first and second handles. A pin extending from the link engages the camways and upon closure of the handles provides a clamping action.
Claims7
A pliers for clamping a hose comprising in combination:
- a first lever arm including a first jaw at one end, a handle at the opposite end and an intermediate pivot;
- a second lever arm including a pivot at one end connected with the intermediate pivot of the first lever arm, and including a handle at the opposite end opposed to and aligned with the first lever arm handle;
- a jaw member including a pivot connected to the pivots of the first and second lever arms for pivoting about a common pivot axis and further including a second jaw in opposed relation to the first jaw;
- and
- a connecting link pivotally attached at one end to the jaw member and including a cam member engaged at the opposite end of the link simultaneously to a first cam pathway in the first lever arm and a second cam pathway in the second lever arm, said first and second cam pathways each being radially spaced from the common pivot axis whereby closure of the handles by movement of the handles toward each other about the common pivot axis effects movement of the jaws toward each other.

A pliers for clamping a hose comprising, in combination:
- a first arm with an intermediate first pivot, a first jaw at one end, a handle at the opposite end and a first cam slot spaced from the pivot,
- a second arm with a second pivot at one end, a handle at the opposite end, and a second cam slot intermediate the handle and pivot, said second cam slot overlying the first cam slot, said first and second pivots being congruent;
- a jaw member including a second jaw and a jaw member pivot congruent with the first and second arm pivots;
- and
- a link pivotally connected to the jaw member by a jaw member pivot connection and to the first and second cam slots by a cam member engaging simultaneously the first and second slots, whereby the jaws are moved toward each other in response to movement of the handles toward each other.
