1. In a shears or like tool, first and second jaws pivotally connected together and between which an object is engaged, a handle member pivotally connected to the first jaw adjacent its outer edge, a second handle member fixed to the first jaw, a lever pivotally connected at one end to the pivoted handle member below the pivotal connection of the handle member to the first jaw, the second jaw having a slot for engagement by the opposite end of the lever, said slot having a serrated edge, and spring means operative on the lever for biasing same into engagement with the serrated edge.
2. In a shears or like tool, first and second jaws pivotally connected together and between which an object is engaged, a handle member pivotally connected to the first jaw, a second handle member fixed to the first jaw, a lever pivotally connected at one end to the pivoted handle memher, the second jaw having a slot for engagement by the opposite end of the lever, said slot having a serrated edge, and spring means operative on the lever for biasing same into engagement with the serrated edge, the slotted and serrated jaw having its serrations along a longitudinal edge of its slot, the lever having an end portion straddling the slotted jaw and provided with a crosss pin located in the slot for engagement with the serrations.
3. In a shears or like tool having first and second cooperating jaws, said jaws being pivotally connected together, the second of the jaws having a cutting edge and the first jaw having an anvil portion for cooperation with the cutting edge, a handle rigidly attached to the first jaw, a second handle pivotally attached to the first jaw, a lever pivoted at one end to the pivotally-attached handle, the second jaw having an elongated slot having one of its edges defined by ratchet teeth, the second end of the lever having a pin extending through the slot for engagement with the ratchet teeth therein, and a spring engaging the lever and operative to bias it to bring the pin toward the ratchet teeth.
4. In a shears or like tool according to claim 3, and including a pivoted latch member carried by the lever and having a hooked end, and a pin carried by the pivoted handle for engagement by the hooked end of said latch member.
5. In a shears or like tool according to claim 4, wherein the second jaw has a notch in its edge facing the pivoted handle, and the latch member has an end portion engaged by the notch.
6. A shears or similar tool comprising, a first jaw and a second jaw pivotally connected together, the first jaw having an anvil portion and a projecting, internally-serrated nose portion overlying the forward end of the anvil portion, the second jaw having a shank provided with an elongated slot having one of its edges defined by ratchet teeth, a handle pivoted on the first jaw, a link pivoted at one end to the handle at a point adjacent to its pivotal connection to the first jaw, a pin at the opposite end of the link, said pin entering the slot and engaging the ratchet teeth therein, spring means for biasing the link to bring the pin thereon into engagement with the ratchet teeth, a spring-biased latch member carried by the link, and a pin carried by the pivoted handle for engagement by said latch member.
7. In a shears or similar tool the combination with elongated handles of first and second jaws, said first jaw being bifurcated, a first handle fixedly connected thereto, an anvil portion of said bifurcated jaw, a hollow shank, and a second handle having fixed connection therewith, the upper end of said shank being pivotally connected to the first named jaw, adjacent its outer edge and removed from said anvil portion, a jaw including a cutting blade pivotally connected to the bifurcated jaw member and projecting downwardly between the bifurcations to a point between the handles and a fulcrum link pivotally connected to the lower end of the cutting blade and to the upper end of the hollow shank whereby movement of the handles toward and from each other will actuate the cutting blade to and from a cutting position with respect to the anvil.
