Abstract
Abstract A combination tool for opening wrecked vehicles and the like comprising a first elongated tool member having first and second ends with a bore extending thereinto from one end thereof. A second elongated tool member is selectively slidably received in the bore of the first tool member and has a tool head portion at its outer end. The tool head portion includes a pry bar means, cutting means and spike means mounted thereon. The first tool member is selectively slidably movable with respect to the second tool member to effectively extend the length of the tool to provide additional leverage for the tool head portion when the same is being used to open a wrecked vehicle. The first tool member includes a hammer head at one end thereof which may be used to strike the tool head portion when the tool members are separated to create additional impact force to the tool head portion. The first tool member may also be struck against the second tool member by slidably moving the same with respect to each other to aid the cutting means in penetrating metal materials.

A combination tool for opening wrecked vehicles and the like, comprising, a first elongated tool member having first and second ends and a bore extending thereinto from said one end, a second elongated tool member having a first end portion selectively slidably received in said bore of said first tool member and having a tool head portion at its other end, said first tool member being selectively slidably moved outwardly with respect to said second tool member first end portion to extend the length of the tool to provide additional leverage for the tool head portion when the same portion is being used to open a wrecked vehicle, said tool head portion and said one end of said first tool member having registering strike areas thereon whereby said first tool member may be slidably moved with respect to said second tool member to cause said strike areas thereon to be struck against the strike area on said tool head portion to cause impact forces to be transferred to said tool head portion, a hammer head means being mounted on said other end of said first tool member, said hammer head means having an elongated shape and being transversely disposed with respect to the longitudinal axis of said first tool member, said elongated shape permitting said hammer head means to also serve as a handle means, and said tool head portion having a first flat surface provided thereon to provide a first hammer striking surface for said hammer head means when said first and second tool members are separated, a pry bar means being mounted on said tool head portion extending laterally therefrom, said pry bar means having a tip portion at its outer end, said first hammer striking surface being disposed on said tool head portion whereby blows delivered to said first hammer striking surface will be transmitted to said tip portion, said first end of said second tool member having a chisel means formed at the end thereof said tool head portion having a second hammer striking surface provided thereon which is disposed with respect thereto so that blows delivered to said second hammer striking surface will be transmitted to said chisel means, and a spike means secured to said tool head portion extending outwardly therefrom.
Claim 3
Dependent Claim
105 words
The tool of claim 1 wherein a cutting means is mounted on said tool head portion and extends outwardly therefrom, said cutting means comprising first and second angularly disposed cutting edges which face away from said first end portion of said second tool member, said cutting means having a sharpened tip portion at its outer end adapted to pierce metal material to provide an initial opening for said cutting edges in said metal material, saId cutting means being disposed so that the slidable striking of said first tool member on said second tool member causes said cutting edges to cut through the said metal material.
Claim 4
Dependent Claim
12 words
The tool of claim 1 wherein said hammer head means is cylindrical.
