Abstract
Abstract 1. A device of the character described comprising the combination of a guide tube having a normally open end, a support frame having a port therethrough, linkage means pivotally connected with the tube and with the frame and rotatably supporting the tube for movement between a position in longitudinal alignment with said port and with its open end in registry with the port and an additional position in which the tube lies adjacent the port with a side portion of the tube extending generally transversely across said port, an elongated track carried by said frame disposed generally parallel to and adjacent the tube in its said additional position, means connected with and projecting laterally from said tube adjacent its open end engaging and movable along said elongated track for cooperating with the track to direct the tube during movement between said positions, and means carried by the tube for moving an article therethrough toward and away from said port.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
158 words
A device of the character described comprising the combination of a guide tube having a normally open end, a support frame having a port therethrough, linkage means pivotally connected with the tube and with the frame and rotatably supporting the tube for movement between a position in longitudinal alignment with said port and with its open end in registry with the port and an additional position in which the tube lies adjacent the port with a side portion of the tube extending generally transversely across said port, an elongated track carried by said frame disposed generally parallel to and adjacent the tube in its said additional position, means connected with and projecting laterally from said tube adjacent its open end engaging and movable along said elongated track for cooperating with the track to direct the tube during movement between said positions, and means carried by the tube for moving an article therethrough toward and away from said port.
Claim 2
Independent Claim
158 words
A device of the character described comprising the combination of a guide tube having a normally open end, a support frame having a port therethrough, linkage means pivotally connected with the tube and with the frame and rotatably supporting the tube for movement between a position in longitudinal alignment with said port and with its open end in registry with the port and an additional position in which the tube lies adjacent the port with a side portion of the tube extending generally transversely across said port, an elongated track carried by said frame disposed generally parallel to and adjacent the tube in its said additional position, means connected with and projecting laterally from said tube adjacent its open end engaging and movable along said elongated track for cooperating with the track to direct the tube during movement between said positions, and means carried by the tube for moving an article therethrough toward and away from said port.
Claim 3
Dependent Claim
46 words
A device as claimed in claim 1, in which said means carried by the tube comprises a rotatable threaded shaft disposed longitudinally of the tube and housed within a channel in a wall of the tube, and means carried by the tube rotatably supporting said shaft.
Claim 4
Dependent Claim
61 words
A device as claimed in claim 1, in which said means carried by the tube comprises a rotatable threaded shaft disposed longitudinally of the tube and housed within a channel in a wall of the tube, means carried by the tube rotatably supporting said shaft and a drive motor and gearing are carried by the tube for rotating said threaded shaft.
Claim 5
Dependent Claim
75 words
A device as claimed in claim 1, in which said means carried by the tube comprises a pair of rotatable spaced apart threaded shafts disposed longitudinally of the tube and housed in channels in a wall of the tube, means carried by the tube rotatably supporting said shaft and a crossbar extending between and in threaded engagement with each of said spaced shafts for movement lengthwise of the tube upon rotation of the spaced shafts.
Claim 6
Dependent Claim
60 words
A device as claimed in claim 1, in which the track comprises a rotatable threaded shaft, a nut member is carried by the laterally projecting means and engages said threaded shaft, and drive means is carried by the support frame and operatively connected with an upper end of said threaded shaft for rotating the same to thereby move said tube.
Claim 7
Dependent Claim
65 words
A device as claimed in claim 1, in which means including a yieldably supported member is carried by the guide tube intermediate its ends and at a side portion thereof registrable with said port to exert pressure against an article and yieldably retain the article in said port when the tube is disposed in said additional position with said side portion extending across the port.
Claim 8
Dependent Claim
59 words
A device as claimed in claim 1, in which means is carried by the guide tube intermediate its ends and at a side portion thereof registrable with said port to exert pressure against an article and retain the article in said port when the tube is disposed in said additional position with said side portion extending across the port.
Claim 9
Dependent Claim
54 words
A device as claimed in claim 7, in which the guide tube is provided with a movable wall portion at a side thereof opposite said article retaining means and adjacent the normally open end of the guide tube to facilitate insertion and removal of articles when the tube is disposed in said additional position.
Claim 10
Dependent Claim
104 words
A device as claimed in claim 1, in which said means carried by the tube comprises a rotatable threaded shaft disposed longitudinally of the tube, bearings are carried by said tube for rotatably supporting the shaft, means is carried by the tube for rotating said shaft, threaded means engages said shaft and is movable longitudinally of the shaft and tube in response to rotation of the shaft, and article-attaching means is provided in the tube and engaging said threaded means having a projectible member for cooperating with a recess in a wall of an adjacent opening to retain the article-attaching means in the opening.
