Abstract

An improved fuse removing apparatus including an elongated housing, a pair of complementary jaws extending generally longitudinally outwardly from the housing for engagement with a fuse. The complementary jaws are secured within the housing in longitudinal sliding relationship such that a plate at the end of the housing forces the jaws towards each other when the complementary jaws are urged into the housing. A cap disposed over the plate causes the jaws to rotate during use so as to lockingly engage the plate and thereby firmly grip a fuse without having to manually rotate the housing. All that is necessary to lock the device onto the fuse is to simply push the apparatus onto the exposed part of a fuse. A minimum of manual rotation is all that is required to disengage the jaws from the locking plate, and thereby release the retained fuse.

Claims

1. An improved fuse pulling apparatus comprising an elongated housing;

a pair of complementary jaws slidably mounted within said housing and extending partially outwardly thereof, means for urging the jaws towards one another as the jaws are moved into the housing including a stationary plate having a substantially rectangular opening through which said pair of jaws are disposed, means for urging the jaws to rotate as the jaws are moved into the housing, and means for locking the jaws in a closed position such that forward movement without manual rotation of the device would cause the jaws to lock onto a fuse, said means for locking the jaws in a closed position includes at least one notch in each said jaw of a thickness slightly greater than that of said plate whereby each of said jaws may be disposed onto the edge of said plate when said notches are brought into adjacent position therewith.

2. An apparatus as claimed in claim 1, further including a spring mounted within said housing urging said jaws outwardly of the housing.

3. An apparatus as claimed in claim 2, further including a rivet disposed through said housing to bias said spring against said movement relative to said housing.

4. An apparatus as claimed in claim 3, further including an electrical probe electrically connected to an electrical lamp which is in electrical contact with said rivet such that the device may function as a circuit tester in combination with the fuse pulling apparatus.

5. An apparatus as claimed in claim 4, further including an electrical plug adapted to fittingly engage said rivet, said rivet being of an electrically conductive material, and an electrical wire extending from said electrical plug having a spade terminal at the end thereof.

6. An apparatus as claimed in claim 5, wherein said electrical lamp is a festoon type bulb.

7. An apparatus as claimed in claim 6, wherein said housing has an opening adjacent said bulb to allow external viewing thereof.
