Abstract
Abstract This invention relates to an apparatus for moving a plurality of two-piece canning jar-type lids in series to a feed mechanism in the form of a magazine which will single-line the caps and maintain them in assembled position. The single-lining mechanism is designed to feed lids into the path of movement of a plurality of containers, also moving in series on their sides with their axes horizontal. The caps or lids are carried at an angle to the path of movement of the finish of the jars such as that the finish of the jars or containers will each individually remove a cap from the supply of caps. The caps are then retained on the finish of the jar and are moved with the jar, in a linear path, with the caps being rotated by frictional engagement and thereby threaded onto the finish of the containers.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
153 words
Apparatus for assembling threaded, two-piece closures to glass containers comprising: a conveyor for moving containers in an upright position in series; means for engaging the moving containers and turning the containers with their axes substantially horizontal with the threaded finish of the containers extending in the same direction; means for moving assembled two-piece closures in series, on edge to an assembly point adjacent the finish of the containers, said closures having their open ends facing in the direction of the container finishes; means for guiding the leading edge of the closure skirt into engagement with the container finish as the two are moving in a generally parallel, linear path; means for maintaining the container and closure in firm engagement; and stationary means engaging the side of the skirt of the closure while maintaining the container in a relative nonrotative state whereby the closure is rotated relative to the container finish and threaded thereon.
Claim 2
Dependent Claim
153 words
Apparatus for assembling threaded, two-piece closures to glass containers comprising: a conveyor for moving containers in an upright position in series; means for engaging the moving containers and turning the containers with their axes substantially horizontal with the threaded finish of the containers extending in the same direction; means for moving assembled two-piece closures in series, on edge to an assembly point adjacent the finish of the containers, said closures having their open ends facing in the direction of the container finishes; means for guiding the leading edge of the closure skirt into engagement with the container finish as the two are moving in a generally parallel, linear path; means for maintaining the container and closure in firm engagement; and stationary means engaging the side of the skirt of the closure while maintaining the container in a relative nonrotative state whereby the closure is rotated relative to the container finish and threaded thereon.
Claim 3
Dependent Claim
22 words
The apparatus of claim 1 further including means for supporting the containers elevated from said conveyor when the containers are generally horizontal.
Claim 4
Dependent Claim
33 words
The apparatus of claim 1 wherein said means for maintaining said container and closure in firm engagement comprises a vertical plate and means for biasing said plate in the direction of the containers.
Claim 5
Dependent Claim
15 words
The apparatus of claim 3 wherein said biasing means comprises a plurality of compression springs.
Claim 6
Dependent Claim
21 words
The apparatus of claim 1 further including means for uprighting the containers after the closure has been applied to the containers.
Claim 7
Dependent Claim
24 words
The apparatus of claim 3 further including guide means for returning the containers to an upright position after the closure has been applied thereto.
Claim 8
Dependent Claim
32 words
The apparatus of claim 1 wherein said means comprises a rubber covered member positioned along the path of movement of the containers at the approximate level of the side of the closures.
