Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
136 words
An automatic core loader for a plurality of cores comprising a core box, said core box including spatial support means for aligning said cores concentrically to each other and along the longitudinal axis of said core box, a mandrel upon which said cores are to be spatially placed, support and motive means for advancing said core box along the longitudinal axis of said mandrel and concentrically therewith so as to spatially place said cores along the outer surface of said mandrel, and means for supplying cores to said core box, said means for supplying cores while said core box is advancing to said core box comprises a hopper for storing said cores and dispensing said cores, and a chute in communication with said hopper at one end and with said core box at the other end.
Claim 2
Dependent Claim
136 words
An automatic core loader for a plurality of cores comprising a core box, said core box including spatial support means for aligning said cores concentrically to each other and along the longitudinal axis of said core box, a mandrel upon which said cores are to be spatially placed, support and motive means for advancing said core box along the longitudinal axis of said mandrel and concentrically therewith so as to spatially place said cores along the outer surface of said mandrel, and means for supplying cores to said core box, said means for supplying cores while said core box is advancing to said core box comprises a hopper for storing said cores and dispensing said cores, and a chute in communication with said hopper at one end and with said core box at the other end.
Claim 3
Dependent Claim
23 words
The structure recited in claim 1 and further including motive means for advancing said core box along the longitudinal axis of said mandrel.
Claim 4
Dependent Claim
26 words
The structure recited in claim 2 wherein said mandrel includes radially outward movable segments for frictionally retaining said cores upon the outer surface of said mandrel.
Claim 5
Dependent Claim
30 words
The structure recited in claim 3 wherein said mandrel further includes an expansible boot radially inwardly of said segments for moving said segments radially outwardly when said boot is expanded.
Claim 6
Dependent Claim
42 words
The structure recited in claim 4 wherein said boot includes a valve for admitting and retaining high pressure air within said boot, and further including high pressure air supply means engageable with said valve after said mandrel is loaded with said cores.
Claim 7
Dependent Claim
39 words
The structure recited in claim 5 and further including a bracket at the right handmost end portion of said mandrel to support the latter while the left handmost end portion of said mandrel slidably rests on said core box.
Claim 8
Dependent Claim
36 words
The structure recited in claim 4 and further including mandrel motive means for placing said mandrel upon said core box and said bracket and removing said mandrel therefrom after cores have been placed in said slots.
Claim 9
Dependent Claim
47 words
The structure recited in claim 4 and further including sensing means to determine the position of said core box relative to said chute, and plunger means carried by said chute actuated by said sensing means when said core box is not in a position to receive cores.
Claim 10
Dependent Claim
41 words
The structure recited in claim 1 wherein said core box is movable along one plane, and said chute extends transverse to said plane at an included angle of less than 90* measured from the direction in which said box is headed.
Claim 11
Dependent Claim
45 words
The structure recited in claim 1 and further including a magazine for said mandrel, a link for receiving said mandrel, support means for receiving said mandrel, and motive means for moving said link to a first position to transport said mandrel upon said support means.
Claim 12
Dependent Claim
24 words
The structure recited in claim 2 wherein said motive means is movable to a second position for removing said mandrel from said support means.
Claim 13
Dependent Claim
63 words
The structure recited in claim 1 wherein said mandrel includes an inflatable boot having a valve, a nozzle movable on predetermined conditions into and out of engagement with said valve, a tube connected to said nozzle and to a source of high pressure air, and piston means connected to said tube for moving said nozzle into and out of engagement with said valve.
Claim 14
Dependent Claim
53 words
The structure reciTed in claim 1 wherein successive mandrels are loaded with cores in alternate positions, and further including switch means actuated by the position of said mandrel along the length of said machine, and motive means positioning said switch means in one of two positions alternately in successive cycles of said machine.
Claim 15
Dependent Claim
62 words
The structure recited in claim 1 and further including drive means for moving said core box means to a position under said mandrel and out from thereunder, motor means for actuating said drive means, and switch means for energizing said motor means to move said core means under said mandrel and to move said core box means out from under said mandrel.
Claim 16
Dependent Claim
40 words
