Abstract
Abstract A device for transferring articles from one conveyor onto a second conveyor or a discharge station which comprises a field of single wheels that support the articles during the transfer thereof, each of the wheels being tilted and drivable, and steerable in a horizontal plane. The wheels can be adapted for steering through any desired angular range, i.e., 90°, less than 90°, or up to and including 360°, or greater. Accordingly, articles received on the present tranfer station from an incoming conveyor can be discharged therefrom at a right, acute or obtuse angle, in either a curved or straight path, and a control feature can be included with the transfer station whereby horizontal alignment of an article on its vertical axis can be maintained or altered according to preference.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
150 words
A transfer station for transferring articles from a conveyor, (a) said transfer station comprising a field of single wheels that support said articles during the transfer thereof, each of said wheels being tilted and drivable, and steerable in a horizontal plane, (b) each of said wheels being attached to a tilted axle that is supported by an axle mount, said mount having a vertically disposed lower section with a steering wheel attached thereto, said steering wheel having a vertical axis, (c) a support member on which said lower section of the axle mount is rotatably mounted, and (d) a driving wheel rotatably mounted on said vertically disposed lower section of the axle mount above said steering wheel and below said wheel attached to the axle, the rim of said wheel attached to the axle being in frictional contact with the hub of the driving wheel and turned by rotation thereof.
Claim 2
Dependent Claim
150 words
A transfer station for transferring articles from a conveyor, (a) said transfer station comprising a field of single wheels that support said articles during the transfer thereof, each of said wheels being tilted and drivable, and steerable in a horizontal plane, (b) each of said wheels being attached to a tilted axle that is supported by an axle mount, said mount having a vertically disposed lower section with a steering wheel attached thereto, said steering wheel having a vertical axis, (c) a support member on which said lower section of the axle mount is rotatably mounted, and (d) a driving wheel rotatably mounted on said vertically disposed lower section of the axle mount above said steering wheel and below said wheel attached to the axle, the rim of said wheel attached to the axle being in frictional contact with the hub of the driving wheel and turned by rotation thereof.
Claim 3
Dependent Claim
88 words
A transfer station for transferring articles from a conveyor, said transfer station comprising a field of single wheels that support said articles during the transfer thereof, each of said wheels being tilted at a non-vertical fixed angle from a horizontal plane and drivable, and steerable in a horizontal plane about an upwardly projecting axis, said field of single tilted wheels being positioned in a plurality of rows with individual wheels in a single row being tilted in opposite directions but driven for article movement in the same direction.
Claim 4
Dependent Claim
88 words
A transfer station for transferring articles from a conveyor, said transfer station comprising a field of single wheels that support said articles during the transfer thereof, each of said wheels being tilted at a non-vertical fixed angle from a horizontal plane and drivable, and steerable in a horizontal plane about an upwardly projecting axis, said field of single tilted wheels being positioned in a plurality of rows with individual wheels in a single row being tilted in opposite directions but driven for article movement in the same direction.
Claim 5
Dependent Claim
88 words
A transfer station for transferring articles from a conveyor, said transfer station comprising a field of single wheels that support said articles during the transfer thereof, each of said wheels being tilted at a non-vertical fixed angle from a horizontal plane and drivable, and steerable in a horizontal plane about an upwardly projecting axis, said field of single tilted wheels being positioned in a plurality of rows with individual adjacent wheels in separate rows being tilted in opposite directions but driven for article movement in the same direction.
Claim 6
Dependent Claim
88 words
A transfer station for transferring articles from a conveyor, said transfer station comprising a field of single wheels that support said articles during the transfer thereof, each of said wheels being tilted at a non-vertical fixed angle from a horizontal plane and drivable, and steerable in a horizontal plane about an upwardly projecting axis, said field of single tilted wheels being positioned in a plurality of rows with individual adjacent wheels in separate rows being tilted in opposite directions but driven for article movement in the same direction.
Claim 7
Dependent Claim
83 words
A transfer station for transferring articles from a conveyor, said transfer station comprising a field of single wheels that support said articles during the transfer thereof, each of said wheels being tilted at a non-vertical fixed angle from a horizontal plane and drivable, and steerable in a horizontal plane about an upwardly projecting axis, said wheels being driven through drive shafts and including an endless flexible drive member operably associated with said drive shafts and simultaneously driving selected drive shafts in opposite directions.
Claim 8
Dependent Claim
83 words
A transfer station for transferring articles from a conveyor, said transfer station comprising a field of single wheels that support said articles during the transfer thereof, each of said wheels being tilted at a non-vertical fixed angle from a horizontal plane and drivable, and steerable in a horizontal plane about an upwardly projecting axis, said wheels being driven through drive shafts and including an endless flexible drive member operably associated with said drive shafts and simultaneously driving selected drive shafts in opposite directions.
Claim 9
Dependent Claim
78 words
A transfer station for transferring articles from a conveyor, said transfer station comprising a field of single wheels that support said articles during the transfer thereof, each of said wheels being tilted at a non-vertical fixed angle from a horizontal plane and drivable, and steerable in a horizontal plane about an upwardly projecting axis, selected wheels being tilted in opposite directions and such wheels tilted in opposite directions are steered simultaneously by angular displacement in the same direction.
Claim 10
Dependent Claim
