Abstract
Abstract Apparatus for sequentially compacting a plurality of containers includes first and second plates each juxtaposed with respect to the other and having respective compacting surfaces, one of the plates being operated by a cam for effecting the reciprocal operation toward and away from the other plate so as to crush containers between the two compacting surfaces. A magazine is provided above the compacting plates for feeding the containers into the space therebetween, the magazine being pivoted above the plates such that downward rotation of the magazine occurs responsive to the weight of a predetermined number of the containers to operate a switch which energizes the cam mechanism.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
156 words
Apparatus for sequentially compacting a plurality of containers comprising: a first plate having a first compacting surface; a second plate juxtaposed with said first plate and having a second compacting surface; means for reciprocally moving said second plate toward and away from said first plate so as to effect compacting of containers between said first and second compacting surfaces; a magazine for sequentially feeding most of said containers into the space between said first and second plates when in an open, noncompacting position; means for energizing said reciprocal moving means responsive to the weight of a predetermined number of said containers in said magazine and continuously operating said moving means during any energization cycle thereof until most of said predetermined number of containers are compacted; a first shaft; and means coupling said moving means and said sequential feeding means to said first shaft so that each is commonly operative responsive to rotation of said first shaft.
Claim 2
Dependent Claim
156 words
Apparatus for sequentially compacting a plurality of containers comprising: a first plate having a first compacting surface; a second plate juxtaposed with said first plate and having a second compacting surface; means for reciprocally moving said second plate toward and away from said first plate so as to effect compacting of containers between said first and second compacting surfaces; a magazine for sequentially feeding most of said containers into the space between said first and second plates when in an open, noncompacting position; means for energizing said reciprocal moving means responsive to the weight of a predetermined number of said containers in said magazine and continuously operating said moving means during any energization cycle thereof until most of said predetermined number of containers are compacted; a first shaft; and means coupling said moving means and said sequential feeding means to said first shaft so that each is commonly operative responsive to rotation of said first shaft.
Claim 3
Dependent Claim
85 words
The apparatus recited in claim 1 further comprising: said magazine having an input end and a discharge end; means for supporting said magazine such that said discharge end is positioned over said first and second plates wherein containers exiting said discharge end are gravity fed into said space between said first and second plates when said plates are in said open, noncompacting position; and said supporting means further including means for supporting said input end in an elevated position with respect to said discharge end.
Claim 4
Dependent Claim
78 words
The apparatus recited in claim 2 wherein said energizing means comprises: means for pivoting said magazine to said support means about a pivot axis between said discharge end and said input end, said pivot axis being substantially normal to the direction of container feed along said magazine; and biasing means for maintaining said input end of said magazine in a down position until overcome by the weight of said predetermined number of containers on said discharge end thereof.
Claim 5
Dependent Claim
36 words
The apparatus recited in claim 3 further comprising means at said input end of said magazine for holding said input end in an up position until most of said containers have passed across said discharge end.
Claim 6
Dependent Claim
50 words
The apparatus recited in claim 4 further comprising: a container stop along said magazine toward said discharge end; and wherein said magazine and said stop are dimensioned such that said containers pass underneath said stop after the downward rotation of said discharge end of said magazine about said pivot axis.
Claim 7
Dependent Claim
48 words
The apparatus recited in claim 3 wherein said reciprocal moving means further comprises: a shaft carried by said supporting means; and a cam rotatable with said shaft and having a cam surface bearing against said second plate to effect movement of said second plate toward said first plate.
Claim 8
Dependent Claim
28 words
The apparatus recited in claim 6 wherein said reciprocal moving means comprises: a prime mover; and means coupling said shaft to said prime mover to effect rotation thereof.
Claim 9
Dependent Claim
50 words
The apparatus recited in claim 7 wherein said energizing means further comprises: a first switch; means for operating said switch responsive to a downward movement of said discharge end of said magazine about said pivot axis; and means for energizing said prime mover responsive to operation of said first switch.
Claim 10
Dependent Claim
52 words
The apparatus recited in claim 6 further comprising: means for sequentially feeding each of said predetermined number of cans into said space between said first and second surfaces; and means coupled between said feeding means and said shaft so as to effect operaation of said feeding means by rotation of said shaft.
Claim 11
Dependent Claim
46 words
The apparatus recited in claim 9 wherein said feeding means comprises a generally U-shaped bracket rotatably mounted adjacent said discharge end of said magazine for sequentially receiving said containers, said shaft effecting rotation of said bracket to cause sequential feeding of each container into said space.
Claim 12
Dependent Claim
31 words
The apparatus recited in claim 3 wherein said continuous operating means comprises a first switch for energizing said moving means responsive to a downward movement of said discharge end of magazine.
Claim 13
Dependent Claim
35 words
The apparatus recited in claim 11 wherein said continuous operating means further comprises a second switch coupled to said second plate for continuing energization of said moving means responsive to movement of said second plate.
Claim 14
Dependent Claim
123 words
Apparatus for sequentially compacting a plurality of containers, comprising: first and second compacting members having respective first and second compacting surfaces; means for moving one of said compacting members toward and away from the other compacting member so as to effect compacting of containers between said first and second compacting surfaces; a magazine for holding said containers; means for sequentially feeding said containers from said magazine and into the space between said first and second compacting surfaces when apart in an open, non-compacting position; means for simultaneously energizing said moving means and said sequential feeding means responsive to the presence of a predetermined weight of said containers in said magazine; and means coupling said sequential feeding means in synchronization with said moving means.
Claim 15
Dependent Claim
123 words
Apparatus for sequentially compacting a plurality of containers, comprising: first and second compacting members having respective first and second compacting surfaces; means for moving one of said compacting members toward and away from the other compacting member so as to effect compacting of containers between said first and second compacting surfaces; a magazine for holding said containers; means for sequentially feeding said containers from said magazine and into the space between said first and second compacting surfaces when apart in an open, non-compacting position; means for simultaneously energizing said moving means and said sequential feeding means responsive to the presence of a predetermined weight of said containers in said magazine; and means coupling said sequential feeding means in synchronization with said moving means.
