Abstract: A mixture of cooling liquids and solid pieces of waste from machine tools drop onto an inclined bottom wall of the upper, generally vertically disposed section of an inverted, generally Y-shaped feed chute. One of the two lower, diverging chute sections extends downwardly and rearwardly beneath the upper chute section to a chip wringer, and has its upper end positioned beneath the lower edge of the inclined bottom wall of the upper section to receive the liquids and lighter pieces of waste which tend to drop by gravity into this one lower section. The other lower section of the chute is in general alignment with the inclined bottom wall of the upper section to receive the larger pieces of waste which, because of their momentum or size pass beyond the one lower section and into the other lower section. A stream of air which is directed transversely across the lower end of the upper section blows the remaining liquids and light waste into the one lower section.

Abstract: Apparatus for crushing swarf and like materials in which the material to be crushed is received in a supply hopper which includes sensing switch means responsive to material in the hopper reaching a selective level for enabling a control circuit which controls operation of the crusher.
