Abstract:
1. A portable electric can crusher to laterally crush cans, comprising: a support structure having a rigid vertical wall with an elongated rectangular slot formed therethrough attached horizontally to a motor gearbox assembly; an elongated rectangular crushing plate having a crushing plate drive portion carried on the support structure for back and forth movement relative thereto through the elongated rectangular slot in the support structure vertical wall; a ram plate carried by support arms against the vertical wall, said support arms being connected to a drive plate, the ram plate being movable with said drive plate toward and away from the vertical wall; a back pack support enclosure secured underneath the support structure vertical wall, the enclosure defining a crushed can drop space for storage therein and removal therefrom; a switch and a rechargeable battery attached atop said support enclosure for powering a motor; a can crushing chamber defined by the space within the vertical wall and ram plate above the support enclosure; a housing mounted to the support structure vertical wall, said housing having a handle for ease of transport; said drive plate and said crushing plate drive portion comprising dual drive plates having dual drive cam and dual slot means for moving the dual plates in a predetermined relation translation motion wherein the crushing plate is moved to crush the middle of a can in the crushing chamber and the ram plate is moved to crush the ends of a can in the crushing chamber; and said motor gearbox assembly connected horizontally to said motor which is drivingly connected to said dual drive cam and dual slot means by a force transfer block for operating said dual drive plates cooperatively for imparting said predetermined relation translation motion of the plates in response to motion of said force transfer block wherein cans can be repetitively crushed in said crushing chamber.
