Abstract
Abstract Internal gripper apparatus for use in uncasers and the like, for controllably gripping bottles or other containers from within for transport and release as desired. The internal grippers are spring-loaded to an outer position though automatically retract as required for insertion into the mouth of a container, gripping the container near the top, or at the ridge adjacent the top of the container characteristic of nearly all containers. The grippers have an upward extending centrally disposed actuating member which may be slidably encouraged to a lower position to retract the grippers and release a container held thereby. The grippers provide relatively close axial positioning of the containers to provide the desired separation of containers on container handling apparatus, and further include supporting structure to allow retraction of the gripper on engagement with broken or inverted containers or other obstructions in the normal operation of the gripper apparatus.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
138 words
Container gripper apparatus for gripping a container from within upon engagement along a longitudinal axis comprising; a housing means; a plurality of gripper members, said gripper members being equally spaced about the periphery of said housing means adjacent the lower end thereof and extending generally radially outward therefrom, each of said gripper members being coupled to said housing means for rotation between extended and retracted positions about axes generally perpendicular to and spaced from said longitudinal axis; means for yieldably encouraging said gripper members to the extended position; and an actuator, said actuator being slidably coupled to said housing for relative sliding motion with respect thereto in the direction of said longitudinal axis between extended and depressed positions, said actuator being disposed to engage the inward extending ends of said gripper members when moved to said depressed position.
Claim 2
Dependent Claim
138 words
Container gripper apparatus for gripping a container from within upon engagement along a longitudinal axis comprising; a housing means; a plurality of gripper members, said gripper members being equally spaced about the periphery of said housing means adjacent the lower end thereof and extending generally radially outward therefrom, each of said gripper members being coupled to said housing means for rotation between extended and retracted positions about axes generally perpendicular to and spaced from said longitudinal axis; means for yieldably encouraging said gripper members to the extended position; and an actuator, said actuator being slidably coupled to said housing for relative sliding motion with respect thereto in the direction of said longitudinal axis between extended and depressed positions, said actuator being disposed to engage the inward extending ends of said gripper members when moved to said depressed position.
Claim 3
Dependent Claim
17 words
The apparatus of claim 1 wherein said plurality of gripper members comprises at least three gripper members.
Claim 4
Dependent Claim
32 words
The apparatus of claim 1 wherein said actuator is generally slidably housed in said housing means and extends beyond the upper end thereof so as to be accessible for depression from above.
Claim 5
Dependent Claim
18 words
The apparatus of claim 3 further comprised of spring means for encouraging said actuator to the extended position.
Claim 6
Dependent Claim
49 words
The apparatus of claim 1 wherein said gripper members are elongate members rotationally coupled to said housing means near the inner end thereof, said means for yielding encouraging said gripper members to the extended position being a spring means for encouraging the inner end of said gripper members upward.
Claim 7
Dependent Claim
20 words
The apparatus of claim 5 wherein said gripper members extend outward and slightly upward when in the freely extended position.
Claim 8
Dependent Claim
62 words
The apparatus of claim 1 further comprised of a support for coupling to a transport system, and a mounting spring means, said housing means being coupled to said support so as to be movable along said longitudinal axis between upper and lower positions with respect thereto, said mounting spring means being a means for encouraging said housing means to said lower position.
Claim 9
Dependent Claim
14 words
The apparatus of claim 1 wherein said gripper members are self lubricating plastic members.
Claim 10
Dependent Claim
29 words
The apparatus of claim 1 wherein said gripper members in said extended position extend to at least approximately twice the diameter of the periphery of the adjacent housing means.
Claim 11
Dependent Claim
173 words
A container gripper apparatus for engaging and transporting containers of glass, plastic and like materials comprising: a housing means; a plurality of gripper members, said gripper members being equally spaced about the periphery of said housing means adjacent the lower end thereof and extending generally radially outward therefrom, each of said gripper members being coupled to said housing means for rotation between extended and retracted positions about axes generally perpendicular to and spaced from said longitudinal axis, the outer end of said gripper members extending further radially outward when in the extended position than in said retracted position, and being rotatable upward toward said retracted position upon contact with a container opening; means for yieldably encouraging said gripper members to the extended position; and an actuator, said actuator being slidably coupled to said housing for relative sliding motion with respect thereto in the direction of said longitudinal axis between extended and depressed positions, said actuator being disposed to engage the inward extending ends of said gripper members when moved to said depressed position.
Claim 12
Dependent Claim
173 words
A container gripper apparatus for engaging and transporting containers of glass, plastic and like materials comprising: a housing means; a plurality of gripper members, said gripper members being equally spaced about the periphery of said housing means adjacent the lower end thereof and extending generally radially outward therefrom, each of said gripper members being coupled to said housing means for rotation between extended and retracted positions about axes generally perpendicular to and spaced from said longitudinal axis, the outer end of said gripper members extending further radially outward when in the extended position than in said retracted position, and being rotatable upward toward said retracted position upon contact with a container opening; means for yieldably encouraging said gripper members to the extended position; and an actuator, said actuator being slidably coupled to said housing for relative sliding motion with respect thereto in the direction of said longitudinal axis between extended and depressed positions, said actuator being disposed to engage the inward extending ends of said gripper members when moved to said depressed position.
Claim 13
Dependent Claim
17 words
The apparatus of claim 10 wherein said plurality of gripper members comprises at least three gripper members.
Claim 14
Dependent Claim
32 words
The apparatus of claim 10 wherein said actuator is generally slidably housed in said housing means and extends beyond the upper end thereof so as to be accessible for depression from above.
Claim 15
Dependent Claim
18 words
The apparatus of claim 12 further comprised of spring means for encouraging said actuator to the extended position.
Claim 16
Dependent Claim
49 words
The apparatus of claim 10 wherein said gripper members are elongate members rotationally coupled to said housing means near the inner end thereof, said means for yieldably encouraging said gripper members to the extended position being a spring means for encouraging the inner end of said gripper members upward.
Claim 17
Dependent Claim
20 words
The apparatus of claim 14 wherein said gripper members extend outward and slightly upward when in the freely extended position.
Claim 18
Dependent Claim
62 words
The apparatus of claim 10 further comprised of a support for coupling to a transport system and a mounting spring means, said housing means being coupled to said support so as to be movable along said longitudinal axis between upper and lower positions with respect thereto, said mounting spring means being a means for encouraging said housing means to said lower position.
