Abstract
A lopper of the type having an anvil cooperable with a blade actuated by a pair of elongated members made of moldable material, the first member being unitary and comprising a first handle merging into a first gear segment having a central post integral therewith, the first member terminating at a distal end by the anvil, the second elongated member comprising a second handle merging into a second gear segment at one end of the member, the second gear segment having a second post integral therewith, the first and second members being pivotally connected to a metal plate at the central and second posts. The moldable material is most preferably a plastic, but other moldable substances could be employed.
Claims20
A lopper, comprising:
- a metal plate having oppositely facing inner and outer surfaces and a central aperture, a forwardly extending blade and a rearwardly extending tang having a second aperture offset from the central aperture;
- a first elongated member formed as a unitary piece and comprising a first handle merging into a first gear segment and terminating at a distal end by an anvil configured for engagement with the blade;
- and
- a second elongated member comprising a second handle merging into a second gear segment at one end thereof;
- the first and second members being pivotally connected to the plate at the central and second apertures, respectively, so that the gear segments intermesh for pivotal movement of the blade and anvil in response to pivotal movement of the first and second handles about the central and second apertures, respectively.
A lopper having a pair of elongated members made of a moldable material, the lopper comprising:
- a metal plate having oppositely facing inner and outer surfaces and a central aperture, a forwardly extending blade, and a rearwardly extending tang provided with a second aperture formed therein at a position offset from the central aperture;
- a first elongated unitary member pivotally connected to the plate and molded onto the inner surface thereof, the first member comprising a first handle merging into a first gear segment and terminating at a distal end by an anvil configured for engagement with the blade;
- and
- a second elongated member pivotally connected to the plate and molded onto the inner surface thereof, the second member comprising a second handle merging into a second gear segment at one end of the member;
- the relative position of the central and second apertures being such that the gear segments intermesh for pivotal movement of the blade and anvil in response to pivotal movement of the handles.
A method for making a lopper of the type having an anvil cooperable with a blade actuated by a pair of elongated members made of moldable material, the first member being unitary and comprising a first handle merging into a first gear segment having a central post integral therewith, the first member terminating at a distal end by the anvil, the second elongated member comprising a second handle merging into a second gear segment at one end of the second member, the second gear segment having a second post integral therewith, the first and second members being pivotally connected to a metal plate about the posts, the method comprising the steps of:
- positioning into a mold the metal plate having the blade extending forwardly and a rearwardly extending tang, the metal plate having a central aperture and a second aperture offset from the central aperture, each of the apertures having a headed fastener inserted therethrough;
- and
- molding the first and second elongated members onto the metal plate using a moldable plastic such that the central post is formed by filling in the central aperture, and the second post is formed by filling in the second aperture.
