Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
175 words
A machine for removing biscuits from baking pans, comprising a pLatform, infeed conveyor means for serially delivering biscuit-containing pans to said platform, pan swinging means mounted adjacent a lateral edge of said platform, loader means operable in response to delivery of a pan by said conveyor means to said platform to move said pan laterally onto said pan swinging means to enable the latter to turn said pan over to dump the biscuits therefrom and return the thus emptied said pan to said platform, a second conveyor means, pan ejector means operable to move said emptied pan from said platform onto said second conveyor means, a third biscuit conveyor means below and longitudinally aligned with said infeed conveyor means, and transfer means normally disposed in substantial horizontal alignment with said platform for receiving said biscuits from said pan, as the latter is turned over by said pan swinging means, and means for lowering said transfer means below said infeed conveyor means and tilting the same inwardly to deposit said biscuits onto said biscuit conveyor means.
Claim 2
Dependent Claim
175 words
A machine for removing biscuits from baking pans, comprising a pLatform, infeed conveyor means for serially delivering biscuit-containing pans to said platform, pan swinging means mounted adjacent a lateral edge of said platform, loader means operable in response to delivery of a pan by said conveyor means to said platform to move said pan laterally onto said pan swinging means to enable the latter to turn said pan over to dump the biscuits therefrom and return the thus emptied said pan to said platform, a second conveyor means, pan ejector means operable to move said emptied pan from said platform onto said second conveyor means, a third biscuit conveyor means below and longitudinally aligned with said infeed conveyor means, and transfer means normally disposed in substantial horizontal alignment with said platform for receiving said biscuits from said pan, as the latter is turned over by said pan swinging means, and means for lowering said transfer means below said infeed conveyor means and tilting the same inwardly to deposit said biscuits onto said biscuit conveyor means.
Claim 3
Dependent Claim
40 words
A machine according to claim 1, wherein said transfer means comprises tray means for receiving said biscuits top side down, and dumping means for moving said tray means to deposit said biscuits top side up on said biscuit conveyor means.
Claim 4
Dependent Claim
31 words
In a machine according to claim 1, a first variable speed driving means for said infeed and biscuit conveyors, and a second variable speed driving means for said biscuit conveyor means.
Claim 5
Dependent Claim
28 words
In a machine according to claim 3, a main motor means for operating said loader means, said pan swinging means, said pan ejector means, and said transfer means.
Claim 6
Dependent Claim
26 words
A machine according to claim 4, wherein said pan ejector means comprises a double-acting cylinder and piston, and air pressure supply means for actuating the same.
Claim 7
Dependent Claim
39 words
In a machine according to claim 4, a normally deenergized loader clutch interposed between said main motor means and said loader means, and a platform switch operable by a pan delivered to said platform to energize said loader clutch.
Claim 8
Dependent Claim

In a machine according to claim 4, a normally deenergized transfer clutch interposed between said main motor means and said transfer means and energized in response to operation of said pan swinging means.
Claim 10
Dependent Claim
40 words
A machine according to claim 5, wherein said pan ejector means comprises an eject solenoid operable in response to return movement of said pan swinging means to admit air from said supply means to the rear end of said cylinder.
Claim 11
Dependent Claim
42 words
A machine according to claim 9, wherein said pan ejector means comprises a return solenoid operable in response to movement of a pan onto said second conveyor means to admit air from said supply means to the front end of said cylinder.
Claim 12
Dependent Claim
64 words
In a machine according to claim 10, wherein said pan ejector means includes a switch operable by said pan swinging means, a relay having normally closed contacts between said switch and said eject solenoid and normally open contacts between said switch and said return solenoid and operable in response to holding said switch closed to deenergize said eject solenoid and energize said return solenoid.
Claim 13
Dependent Claim
44 words
In a machine according to claim 6, a normally closed safety switch in series with said loader clutch and opened whenever a pan is on said pan swinging means to prevent energizing of said loader clutch in response to closing of said platform switch.
