Abstract
Abstract The invention is an impact tool for compacting trash such as empty cans, bottles, cardboard and paper. It also has other uses such as compacting soil, driving spikes, chopping, edge trimming for lawns, etc. The tool consists of a tubular handle of lightweight material in which is slidably held a driver comprising a relatively heavy shaft. In one embodiment, there is attached to the end of the handle a head made of a strong metal, and when the shaft is slid outwardly and then inwardly, the end thereof strikes the head, thus transferring the kinetic energy of the handle to the head. In use, the head is rested against the bottle or can to be crushed, and the force of the blow either breaks the bottle or flattens the can. In other embodiments, the head is dispensed with so that the driver strikes the trash directly.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
148 words
An impact tool comprising an elongated handle having shaft and head portions and a lengthwise bore extending therein, the head portion being greater in diameter than the shaft portion; a closure member attached to the head portion and extending across and closing the latter; and elongated driver member freely movable lengthwise in said bore toward and away from aid closure member with one end of the driver member being adapted to reach and strike said closure member at the end of each forward stroke whereby the kinetic energy of said driver member is transferred to the closure member and head portion; said closure member being provided with outwardly extending discreet pointed portions adapted to hold the end of the head portion on an article to be crushed, whereby upon a forward stroke of the driver element the kinetic energy of the latter is utilized to crush the article.
Claim 2
Dependent Claim
148 words
An impact tool comprising an elongated handle having shaft and head portions and a lengthwise bore extending therein, the head portion being greater in diameter than the shaft portion; a closure member attached to the head portion and extending across and closing the latter; and elongated driver member freely movable lengthwise in said bore toward and away from aid closure member with one end of the driver member being adapted to reach and strike said closure member at the end of each forward stroke whereby the kinetic energy of said driver member is transferred to the closure member and head portion; said closure member being provided with outwardly extending discreet pointed portions adapted to hold the end of the head portion on an article to be crushed, whereby upon a forward stroke of the driver element the kinetic energy of the latter is utilized to crush the article.
Claim 3
Dependent Claim
64 words
The tool of claim 1 in which the diameter of the head portion progressively decreases along the length of the handle from that portion of the head having said greater diameter to the end of the head portion, thereby providing an outer wall slanting inwardly toward the end of the head portion to enable the latter to be freely separated from material compacted thereby.
Claim 4
Dependent Claim
60 words
The tool of claim 1 in which the outer face of the closure member is provided with said outwardly extending pointed portions at least some of which are adapted to bear against the article to create points of high stress in the article when the driver element strikes the innerface of the closure element, thereby facilitating crushing of the article.
Claim 5
Dependent Claim
22 words
The tool of claim 3 in which said handle is made of high-strength, impact-resisting molded plastic, and said closure member is steel.
Claim 6
Dependent Claim
35 words
The tool of claim 3 in which said closure element constitutes the bottom of a cup-shaped member, the latter being attached to the end of said head portion at the rim of the cup-shaped member.
Claim 7
Dependent Claim
67 words
The tool of claim 5 in which said cup-shaped member is made of steel with said pointed portions being portions of the bottom of said member formed outwardly from the material thereof as hollow cone-shaped projections. 7 The tool of claim 4 including a radially extending shield of synthetic plastic material on said shaft, adapted to deflect any flying particles of the article when it is crushed.
Claim 8
Dependent Claim
38 words
The tool of claim 6 in which an end member of resilient material is attached to said one end of the driver member to act as a cushion when the driver member is moved against said closure member.
Claim 9
Dependent Claim
81 words
The tool of claim 6 in which said pointed portions occur in at least two sets of three Each, the three pointed portions of each set being positioned at the apices of an equilateral triangle, and the altitude of one of said triangles being shorter than that of the other, and the pointed portions at the apices of the other of said triangles projecting a greater distance from the face of said plate, the altitudes of said triangles not being colinear.
Claim 10
Dependent Claim
27 words
The tool of claim 1 in which said head portion constitutes an outwardly flared, bell-shaped portion with said closure member closing the mouth of the bell-shaped portion.
Claim 11
Dependent Claim
45 words
The tool of claim 10 in which said closure member comprises a cup-shaped member, the latter being attached to the mouth of the head portion at the rim of the cup-shaped member, and the wall of the latter tapering inwardly toward the latter''s bottom portion.
