Abstract
Abstract A method and apparatus for separating objects having different resiliencies according to the modulus of elasticity thereof. The objects are passed through a zone and are transversely vibrated at a selected frequency and amplitude to eject those objects having the higher natural frequencies of vibration.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
117 words
A separator for objects of varied firmness comprising: means to channel a stream of objects to be separated through a separating zone, said separating zone comprising a pair of extended surface walls defining a V-shaped trough, vibrator means secured to one of said pair of walls to vibrate the objects in said zone at a controlled amplitude and frequency by imparting vibrations to the separating zone transversely of the length of the trough and normal to the plane of said one wall and selectively bounce therefrom those objects having the higher natural frequencies, first receiving means adjacent said zone for collecting objects bounced therefrom, and second receiving means communicative with said zone for collecting the residual objects.
Claim 2
Dependent Claim
117 words
A separator for objects of varied firmness comprising: means to channel a stream of objects to be separated through a separating zone, said separating zone comprising a pair of extended surface walls defining a V-shaped trough, vibrator means secured to one of said pair of walls to vibrate the objects in said zone at a controlled amplitude and frequency by imparting vibrations to the separating zone transversely of the length of the trough and normal to the plane of said one wall and selectively bounce therefrom those objects having the higher natural frequencies, first receiving means adjacent said zone for collecting objects bounced therefrom, and second receiving means communicative with said zone for collecting the residual objects.
Claim 3
Dependent Claim
131 words
A separator in accordance with claim 1 wherein said first receiving means includes: a second separating zone, said second separating zone comprising a pair of extended surface walls defining a second V-shaped trough, second vibrator means secured to one of said pair of walls of the second separating zone to vibrate objects in said second zone at a controlled amplitude and frequency higher than that of said first zone by imparting vibrations to the separating zone transversely of the length of the second trough and normal to the plane of said one wall thereof to selectively bounce therefrom those objects having the higher natural frequencies, third receiving means adjacent said second zone for receiving objects bounced therefrom, and fourth receiving means communicative with said second zone for receiving objects remaining therein.
Claim 4
Dependent Claim
27 words
A separator in accordance with claim 1 wherein said means to channel a stream of objects includes conveyer means discharging to and transmitting from said separating zone.
Claim 5
Dependent Claim
25 words
A separator in accordance with claim 5 wherein said means to channel a stream of objects further comprises conveyer means transmitting from said receiving means.
