Abstract
Abstract A multipurpose implement for carrying out destructive operations such as cutting, tearing, breaking, and the like. The implement includes an elongated handle assembly for transmitting forces such as impact forces, wedging forces, pushing forces, pulling forces, twisting forces, and the like. A plurality of tools are available for selective connection with the handle assembly to receive the above forces therefrom, these tools being capable of carrying out operations such as wood-cutting and wood-breaking operations, metal-cutting and metal-tearing operations and lockpulling as well as lock-breaking operations. A connecting structure is carried on the one hand by the handle assembly and on the other hand by each of the tools for selectively connecting the tools to the handle assembly, at least some of the tools being capable of connection with the handle assembly in a number of different positions, and at least some of the tools being capable of being connected simultaneously to the handle assembly. Also, at least some of the tools are capable of connection simultaneously to the handle assembly in a selected one of a number of different positions with respect to each other. The tools which can be selectively connected either separately or simultaneously to the handle assembly include an axe-head, capable also of functioning as an adze, a pike, a sheet-metal cutter capable also of functioning as a plaster and lath breaker, and a lock puller, with the axe-head in certain positions also having a chisel function.

Claim 5
Dependent Claim
352 words
A multipurpose implement for carrying out destructive operations comprising elongated handle means for transmitting forces, a plurality of tool means for receiving said forces from said haandle means and for applying said forces to a location where th destructive operation is to be carried out, said plurality of tool means including an axe-head and connecting means operatively connected on the one hand with said handle means and on the other hand with said axe-head for connecting said axe-head to said handle means to be operated thereby, said axe-head having at one end an elongated cutting edge located in a predetermined first plane and at an opposite end a flat hammer surface located in a predetermined second plane perpendicular to said first plane, said axe-head being formed with a pair of mutually perpendicular bores provided with internal threads forming part of said connecting means, one of said bores having an axis located in the plane of said cutting edge and the other of said bores having an axis perpendicular to the plane of said cutting edge and parallel to the plane of said hammer surface, said elongated handle means having at an end region a threaded portion forming part of said connecting means and when located in said bore whose axis is in the plane of said cutting edge providing a normal axe function for said axe-head and when located in said bore whose axis is perpendicular to the plane of said cutting edge providing for said axe-head an adze function, said axe-head being formed with a third bore whose axis is in the plane of said cutting edge, said third bore extending perpendicularly from said flat hammer surface, and said plurality of tool means including a pike stored in said third bore in a position of non-use, said bore whose axis is also in said plane of said cutting edge communicating with said third bore and said handle means when in said first-named bore whose axis is in the plane of said cutting edge coacting with said pike for locking the latter in its stored position of non-use in said third bore.
