Can crusher

Claim 2

A can crusher, comprising: a base having a flat anvil surface thereon extending between opposed base ends; a rigid elongated lever having a handle at an outward handle end and a remaining inward end; a crusher surface on the lever adjacent the remaining lever end extending along the lever from an end adjacent the remaining lever end to an outward end spaced toward the lever handle; bracket means mounted on the base at one of the base ends thereof for mounting the lever at the end end for pivotal movement about an axis parallel to the flat anvil surface, between a closed position with the flat crusher surface in flush engagement with the anvil surface, and an open position wherein the flat crusher surface is pivoted away from the anvil surface to a can receiving position such that a can may be received between the crusher and anvil surface; and a stationary abutment affixed to the base at the end thereof opposite the one end mounting the bracket means, having a can end abutment surface thereon inclined at an acute angle to the anvil surface and adjacent the outer crusher surface end, said abutment being slotted to receive the lever with the abutment surface extending to opposite sides of the lever at the closed position thereof.

Claim 3

The can crusher of claim 1 wherein the lever is formed of an elongated bar of rectangular cross section having a narrow edge thereof coplanar with the flat crusher surface.

Claim 4

The can crusher of claim 1 wherein the inclined abutment surface is oriented in relation to the anvil surface at an angle between 35 and 75 degrees.

Claim 5

The can crusher of claim 1 wherein the inclined abutment surface is oriented in relation to the anvil surface at an angle of approximately 55 degrees.

Claim 6

A can crusher for cans having substantially flat ends joined by substantially cylindrical side walls, the crusher comprising: a base having a flat elongated anvil surface for and abutment with a can side wall; a bracket on the base at one end thereof and adjacent the anvil surface; a lever arm having an inside end mounted to the bracket for pivotal motion about axis parallel to the anvil surface between an open position pivoted away from the anvil surface and a closed position adjacent the anvil surface, and extending to an outward handle end remote from the pivot axis; a crusher surface affixed on the lever arm adjacent the inside end and in a plane substantially parallel to the pivot axis, for engaging a can end resting with its side wall against the anvil surface of the base at the open lever arm position and pivoting with the lever arm to closed position adjacent the anvil surface; an abutment affixed to the base at an end thereof opposite the one end mounting the bracket and having a stationary inclined abutment surface thereon oriented at an acute angle to the anvil surface of the base, for engaging an end of a can; and wherein the crusher surface, anvil surface and inclined abutment surface cooperate to progressively crush a can placed with one end thereof against the inclined abutment surface and the side wall thereof against the anvil surface in response to manual force applied to move the lever arm toward the closed position, such that the can ends will be progressively folded toward one another and flattened along with the can side wall, as the lever arm is manually pivoted about the axis toward the base, said abutment being slotted to receive the lever arm, with the abutment surface extending to opposite sides of the lever arm at its closed position.

Claim 7

A can crusher for cans having substantially flat ends joined by substantially cylindrical side walls, the crusher comprising: a base having a flat elongated anvil surface for and abutment with a can side wall; a bracket on the base at one end thereof and adjacent the anvil surface; a lever arm having an inside end mounted to the bracket for pivotal motion about axis parallel to the anvil surface between an open position pivoted away from the anvil surface and a closed position adjacent the anvil surface, and extending to an outward handle end remote from the pivot axis; a crusher surface affixed on the lever arm adjacent the inside end and in a plane substantially parallel to the pivot axis, for engaging a can end resting with its side wall against the anvil surface of the base at the open lever arm position and pivoting with the lever arm to closed position adjacent the anvil surface; an abutment affixed to the base at an end thereof opposite the one end mounting the bracket and having a stationary inclined abutment surface thereon oriented at an acute angle to the anvil surface of the base, for engaging an end of a can; and wherein the crusher surface, anvil surface and inclined abutment surface cooperate to progressively crush a can placed with one end thereof against the inclined abutment surface and the side wall thereof against the anvil surface in response to manual force applied to move the lever arm toward the closed position, such that the can ends will be progressively folded toward one another and flattened along with the can side wall, as the lever arm is manually pivoted about the axis toward the base, said abutment being slotted to receive the lever arm, with the abutment surface extending to opposite sides of the lever arm at its closed position.

Claim 8

The can crusher of claim 5 wherein the lever arm is formed of an elongated bar of rectangular cross section having a narrow edge thereof coplanar with the flat crusher surface.

Claim 9

The can crusher of claim 5 wherein the inclined abutment surface is oriented in relation to the anvil surface at an angle between 25 and 75 degrees.

Claim 10

The can crusher of claim 5 wherein the inclined abutment surface is oriented in relation to the anvil surface at an angle of approximately 55 degrees.
