Abstract
Abstract Apparatus for breaking glass bottles and for crushing or deforming metallic cans and P.E.T. containers includes a glass bottle disintegrating means and separate can and P.E.T. container crushing means. A common entry chute to the apparatus allows for random introduction of containers to the apparatus but during the delivery travel of a container to the respective disintegrating or crushing means, an air flow sweeping across the container delivery course diverts lighter weight metallic cans and P.E.T. containers to the appropriate crushing means, whereas, heavier weight glass bottles are unaffected by the air flow and pass into the glass bottle disintegrating means.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
224 words
Amended apparatus for disintegrating used glass containers and for sufficiently crushing or deforming used metallic and plastic containers to preclude reuse of such types of containers, said apparatus comprising a housing, glass container disintegrating means disposed in said housing, metallic and plastic container crushing means disposed in said housing situate proximate said glass container disintegrating means, entry chute means carried on said housing for introducing containers into said housing, the course of said chute being disposed such as to provide a gravity induced and supported container travel along a predetermined course in line with said glass container disintegrating means, said chute means including an extension piece which girds a portion of the container periphery, and diverter means carried within said housing and operative to divert any metallic and plastic container introduced therein from its travel along said predetermined course and cause it to be delivered to said metallic and plastic container crushing means, said diverter means comprising an air flow generator discharging a flow of air in a container diverting stream across said container course and including an air manifold extending longitudinally of said travel course adjacent thereto, the quantity and velocity of said flow being sufficient to displace metallic and plastic containers from their girded embrace on said extension piece but insufficient to divert a glass container from its travel in said course.
Claim 2
Dependent Claim
224 words
Amended apparatus for disintegrating used glass containers and for sufficiently crushing or deforming used metallic and plastic containers to preclude reuse of such types of containers, said apparatus comprising a housing, glass container disintegrating means disposed in said housing, metallic and plastic container crushing means disposed in said housing situate proximate said glass container disintegrating means, entry chute means carried on said housing for introducing containers into said housing, the course of said chute being disposed such as to provide a gravity induced and supported container travel along a predetermined course in line with said glass container disintegrating means, said chute means including an extension piece which girds a portion of the container periphery, and diverter means carried within said housing and operative to divert any metallic and plastic container introduced therein from its travel along said predetermined course and cause it to be delivered to said metallic and plastic container crushing means, said diverter means comprising an air flow generator discharging a flow of air in a container diverting stream across said container course and including an air manifold extending longitudinally of said travel course adjacent thereto, the quantity and velocity of said flow being sufficient to displace metallic and plastic containers from their girded embrace on said extension piece but insufficient to divert a glass container from its travel in said course.
Claim 3
Dependent Claim
31 words
The apparatus of claim 1 in which said manifold is disposed relative to said travel course such as to direct air flow thereagainst from a location slightly below said travel course.
Claim 4
Dependent Claim
17 words
The apparatus of claim 1 in which said glass container disintegrating means comprises a rotary impeller unit.
Claim 5
Dependent Claim
22 words
The apparatus of claim 3 further comprising drive means for rotating said glass container disintegrating impeller unit at a relatively high speed.
Claim 6
Dependent Claim
25 words
The apparatus of claim 4 in which said drive means rotates said glass container disintegrating impeller at an impeller tip speed of about 2500 FPM.
Claim 7
Dependent Claim
26 words
The apparatus of claim 1 in which said metallic and plastic container crushing means comprises a pair of impeller, units arranged one spaced above the other.
Claim 8
Dependent Claim
25 words
The apparatus of claim 6 further comprising a drive unit for rotating said pair of metallic and plastic container crushing impellers at relatively low speed.
Claim 9
Dependent Claim
22 words
The apparatus of claim 7 in which the upper impeller unit has 4 vanes and the lower impeller unit has 8 vanes.
Claim 10
Dependent Claim
52 words
The apparatus of claim 7 in which said drive unit rotates said pair of impellers at such speed, and the said pair of impellers so sized that the impeller tip speed of the upper impeller is about 50-70 FPM and the impeller tip speed of the lower impeller is about 35-50 FPM.
Claim 11
Dependent Claim
32 words
The apparatus of claim 6 in which both of said impeller units are plural vane type impellers, the lower impeller unit having a greater number of vanes than the upper impeller unit.
Claim 12
Dependent Claim
51 words
The apparatus of claim 1 in which said extension piece is interiorly of said housing and has a lower end disposed over said glass container disintegrating means, said extension piece having a configuration such as to gird only a minor position of the circumferential periphery of a container sliding endwise therealong.
Claim 13
Dependent Claim
14 words
The apparatus of claim 11 in which said extension piece is a V-section member.
Claim 14
Dependent Claim
48 words
The apparatus of claim 11 comprising a diverted container reception chute disposed adjacent said extension peice and aligned with said metallic and plastic container crushing means for receiving metallic and plastic containers diverted from said travel course by said diverter means and directing them into said crushing means.
