Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
110 words
A machine for alternately loading cores and spacers upon a mandrel comprising a first hopper and a first chute assembly for cores, a second hopper and a second chute assembly for spacers, said chutes terminating with one chute overlying the other chute, escapement means for receiving cores and spacers and through which said cores and spacers pass, and a mandrel aligned with said escapement means to alternately receive said cores and spacers, said escapement means permitting only one pair of cores and spacers to pass through the escapement means at any one time, each pair of cores and spacers being placed upon said escapement means prior to being released therefrom.
Claim 2
Dependent Claim
110 words
A machine for alternately loading cores and spacers upon a mandrel comprising a first hopper and a first chute assembly for cores, a second hopper and a second chute assembly for spacers, said chutes terminating with one chute overlying the other chute, escapement means for receiving cores and spacers and through which said cores and spacers pass, and a mandrel aligned with said escapement means to alternately receive said cores and spacers, said escapement means permitting only one pair of cores and spacers to pass through the escapement means at any one time, each pair of cores and spacers being placed upon said escapement means prior to being released therefrom.
Claim 3
Dependent Claim
35 words
The combination recited in claim 1 wherein said mandrel is disposed beneath said escapement means and in axial alignment with said pair of cores and spacers which drop by gravity upon and around said mandrel.
Claim 4
Dependent Claim
34 words
The combination recited in claim 2 and further including means for restraining the second pair of spacers and cores from moving forward until the first pair of spacers and cores clears said escapement means.
Claim 5
Dependent Claim
26 words
The combination recited in claim 3 and further including additional means for urging forward the spacers and cores behind the second pair of spacers and cores.
Claim 6
Dependent Claim
64 words
The structure of claim 4 wherein said escapement means comprises jaws upon which said pair of cores and spacers are placed, a transition cone attached to said mandrel, motor means for actuating said jaws and said means for restraining the second pair of spacers and cores, timing means for energized said motor means, and indexing means for sequentially aligning mandrels under said escapement means.
Claim 7
Dependent Claim
29 words
The structure of claim 1 wherein said escapement means comprises jaws upon which said pair of cores and spacers are placed and said mandrel is disposed below said jaws.
Claim 8
Dependent Claim
18 words
The structure of claim 6 wherein said escapement means includes a plunger for opening and closing said jaws.
Claim 9
Dependent Claim
33 words
The structure of claim 7 and further including means for restraining the second pair of spacers and cores from moving forward until the first pair of spacers and cores clears said escapement means.
Claim 10
Dependent Claim
15 words
The structure of claim 7 in combination with a transition member attached to said mandrel.
