Abstract

Abstract A bottle crusher formed of an enclosed chute into which bottles are dropped, with a motor driven rotating plate arranged at the lower end of the chute to receive and break the bottles. The motor is located below the plate and mounted upon brackets arranged at spaced points around the periphery of the plate. Vanes are formed upon the upper surface of the plate, with the vanes sloped upwardly from the center of the plate toward the edges and with at least one vane terminating considerably inwardly of the plate edge to form a high point for breaking bottles landing upon it. The bottles are broken by the impacting of the vanes and fragments are thrown upwardly by the slope of the vanes for repeated dropping and impacting, as well as for breaking the bottles between the brackets and vanes, so that the crushed fragments of glass fall off the plate for collection below the plate and motor.

Claims Analysis

Total Claims: 17
Claim 1
Independent Claim 168 words
A breaker for glass articles, such as bottles and the like, comprising: a downwardly directed chute having an upper end into which glass bottles and the like may be inserted, and an open lower end; a horizontally arranged, vertically axised, rotatable plate arranged at and approximately coaxial with said chute lower end, so that the plate at all times closes said lower end; narrow vanes formed on the upper surface of said plate, with said vanes extending radially of the plate and having small area high points formed upon their upper edges for breaking the glass articles dropped upon them, wherein glass articles dropped into the upper end of the chute land upon the plate and vanes so that said high points initially break the articles and thereafter said vanes repeatedly impact the glass articles and fragments of glass therefrom, to break them into desired small size particles which fall off the peripheral edge of the plate; and means located below the plate for collecting the broken particles.
Claim 2
Dependent Claim 168 words
A breaker for glass articles, such as bottles and the like, comprising: a downwardly directed chute having an upper end into which glass bottles and the like may be inserted, and an open lower end; a horizontally arranged, vertically axised, rotatable plate arranged at and approximately coaxial with said chute lower end, so that the plate at all times closes said lower end; narrow vanes formed on the upper surface of said plate, with said vanes extending radially of the plate and having small area high points formed upon their upper edges for breaking the glass articles dropped upon them, wherein glass articles dropped into the upper end of the chute land upon the plate and vanes so that said high points initially break the articles and thereafter said vanes repeatedly impact the glass articles and fragments of glass therefrom, to break them into desired small size particles which fall off the peripheral edge of the plate; and means located below the plate for collecting the broken particles.
Claim 3
Dependent Claim 34 words
A construction as defined in claim 1, and with the upper edges of said vanes being sloped upwardly from the center of the plate radially outwardly, for thereby throwing fragments upwardly of the plate.
Claim 4
Dependent Claim 61 words
A construction as defined in claim 1, and at least one of said vanes extending to close to the peripheral edge of the plate and at least another of said vanes extending to a point considerably inwardly of the peripheral edge of the plate, which point is higher, i.e., above the plate surface, than the high point on said one vane.
Claim 5

Claim 9
Dependent Claim 56 words
A construction as defined in claim 6, and said chute being in the form of a tube whose open low end is arranged in a horizontal plane above and around the plate, and with the tube being bent along its length so that its upper end is formed with an opening arranged in a vertical plane.
Claim 10
Dependent Claim 70 words
