Abstract

An apparatus for crushing workpieces includes a drive mechanism having a gear reduction train and a moveable rack member which is centered above a compression plate for even, linear force transmission. Force is transmitted to the rack member on two opposite sides thereof by a pair of pinions which engage opposite rows of rack teeth. The compression plate is integral with a pair of opposite guide sleeves, which are mounted for sliding movement with respect to vertically extending guideposts. A crimper mechanism is mounted to the compression plate for crimping the workpiece prior to compression. The combination of the improved drive train, which prevents jamming of the apparatus due to uneven force transmission, and the crimper mechanism allows a relatively small motor to be used in the unit, which increases its portability, economy and affordability. An additional aspect of the invention involves an overload sensor arrangement, which causes the apparatus to reverse in mid-stroke if too much compressive force is being generated between the compression plate and the workpiece. A door interlock switch arrangement makes the apparatus safer for use by children or other persons.
