Abstract
Abstract A bobbin tube cage for receiving bobbin tubes dropped therein, for moving tubes so received laterally in an upright position, and for depositing such tubes so moved onto conveyor pegs in an upright position is disclosed and, preferably, comprises an elongate rectangular structure having a substantially open fourth side, a bottom partially open between one or more inwardly directed flanges extending along the bottom from one or more of the facing closed sides, and in particular a guide means having a normally biased swingable gate means fixed for pivotable movement to and outwardly from one of the closed facing sides and having an inwardly directed arcuate convexity partially overlying the lower portion of the open side. The guide means also includes a guide plate fixed between the closed facing sides adjacent their top and across the open side, which guide plate extends downwardly a distance sufficient to somewhat overlap the top portion of a bobbin tube residing within the cage means.

Claim 3
Dependent Claim
137 words
Cage means of claim 1, wherein said guide means comprises gate means pivotably biased and connected to said cage member so as to overlap said side aperture at least in part in a normally closed position for retaining said bobbin tube on-end within said cage member and swingably openable away from said side aperture under an opposing bias of said bobbin tube during its removal from said cage for camming said tube in an on-end orientation during said removal; and guide plate means affixed across the top of said side aperture and extending downward at least to partially overlap the top of a bobbin tube contained within said cage member for retaining said bobbin within said cage member in an on-end orientation and for guiding entry of said bobbin into said cage member in said on-end orientation.

Dependent Claim
28 words
Cage means as in claim 2 wherein said gate means includes at its overlap of said side aperture an arcuate camming convexity directed inwardly of said cage member.
Claim 5
Dependent Claim
27 words
Cage means as in claim 3, wherein said convexity at the top of said gate means downwardly slopes for guiding said bobbin tube into said cage member.
Claim 6
Dependent Claim
27 words
Cage means as in claim 2, wherein said guide plate means includes at its top an arcuate surface for guiding said bobbin tube into said cage member.
Claim 7
Dependent Claim
161 words
In a bobbin tube loading apparatus a laterally movable bobbin tube cage having an open top, a partially open bottom and an open side extending generally vertically therebetween, said cage being adapted to receive an upright textile bobbin tube dropped through said open top thereof thereinto and to support said bobbin tube within said cage for movement with said cage upon said partially open bottom thereof, tube-withdrawing means projectable through said partially open cage bottom and into the open base of said bobbin tube herein for withdrawing said bobbin in tube through said open cage side; said cage including gate means carried by and movable with said cage and movable thereto between open and closed positions, said gate means including a portion overlying in said closed position thereof part of said open cage side to prevent inadvertent discharge therefrom of said bobbin tube deposited therein and moved therewith; and biasing means for resiliently biasing said gate means toward said closed position.
Claim 8
Dependent Claim
161 words
In a bobbin tube loading apparatus a laterally movable bobbin tube cage having an open top, a partially open bottom and an open side extending generally vertically therebetween, said cage being adapted to receive an upright textile bobbin tube dropped through said open top thereof thereinto and to support said bobbin tube within said cage for movement with said cage upon said partially open bottom thereof, tube-withdrawing means projectable through said partially open cage bottom and into the open base of said bobbin tube herein for withdrawing said bobbin in tube through said open cage side; said cage including gate means carried by and movable with said cage and movable thereto between open and closed positions, said gate means including a portion overlying in said closed position thereof part of said open cage side to prevent inadvertent discharge therefrom of said bobbin tube deposited therein and moved therewith; and biasing means for resiliently biasing said gate means toward said closed position.
Claim 9
Dependent Claim
105 words
A cage as in claim 6, wherein said portion of said gate means comprises a flange extending in said closed gate position laterally across at least part of said open side of the cage, said flange having a smooth curved convex surface thereon engageable by said bobbin tube during its withdrawal from said cage. *. A cage as in claim 7, wherein said flange has at an upper end said convexity sloping downwardly and inwardly toward the interior of said cage when in the closed position of said gate means, for deflecting said dropped bobbin upon engaging the same into the interior of said cage.
Claim 10
