Abstract
Abstract A driven roller for use in roller conveyors comprises a cylindrical load-engaging shell provided with a cap in one of its axial ends. The cap has an axial bore which accommodates the sleeve of a driving portion rotatable by a pulley or gear. The sleeve carries one or more spring-biased balls which normally extend into sockets provided in the cap to thus rotate the shell by way of the cap. The balls are expelled from the sockets in response to application of a predetermined force which tends to rotate the sleeve with reference to the cap or vice versa.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
177 words
In a roller conveyor, a driven roller of uniform outer diameter rotatable about a predetermined axis and comprising a load-engaging cylindrical driven portion formed with an axially extending bore; a driving portion rotatable about said axis with and relative to said driven portion, one of said portions comprising at least one female coupling member and the other portion comprising male coupling means including at least one male coupling member received in and engaging with said female coupling member when said driving portion rotates said driven portion, at least one of said coupling members being yieldable to permit disengagement of said coupling members in response to application of a predetermined force which tends to rotate said driving portion with reference to said driven portion or vice versa, said coupling members being located in said bore, and said driving portion comprising a part projecting outwardly from said bore; and drive means for rotating said driving portion and comprising a driving element fixed to said part and having a diameter which is less than said outer diameter of said roller.
Claim 2
Dependent Claim
177 words
In a roller conveyor, a driven roller of uniform outer diameter rotatable about a predetermined axis and comprising a load-engaging cylindrical driven portion formed with an axially extending bore; a driving portion rotatable about said axis with and relative to said driven portion, one of said portions comprising at least one female coupling member and the other portion comprising male coupling means including at least one male coupling member received in and engaging with said female coupling member when said driving portion rotates said driven portion, at least one of said coupling members being yieldable to permit disengagement of said coupling members in response to application of a predetermined force which tends to rotate said driving portion with reference to said driven portion or vice versa, said coupling members being located in said bore, and said driving portion comprising a part projecting outwardly from said bore; and drive means for rotating said driving portion and comprising a driving element fixed to said part and having a diameter which is less than said outer diameter of said roller.
Claim 3
Dependent Claim
32 words
A structure as defined in claim 1, wherein said female coupling member comprises a socket and said male coupling member extends into said socket when said driving portion rotates said driven portion.
Claim 4
Dependent Claim
70 words
A structure as defined in claim 1, wherein said female coupling member comprises a plurality of sockets which are equidistant from each other, as considered in the direction of rotation of said driving portion, and are located at the same distance from said axis, said male coupling means comprising a plurality of male coupling members each received in one of said sockets when said driving portion rotates said driven portion.
Claim 5
Dependent Claim
61 words
A structure as defined in claim 1, wherein said one portion is said driven portion and wherein said female coupling member is located at the inner end of said bore, said driving portion comprising a sleeve extending into said bore and having an end face adjacent to said female coupling member, said male coupling member normally extending beyond said end face.
Claim 6
Dependent Claim
55 words
A structure as defined in claim 1, wherein said female coupling member has an internal surface provided with at least one socket and said other portion comprises a sleeve extending into said female coupling member and having a peripheral surface adjacent to said internal surface, said male coupling member normally extending beyond said peripheral surface.
Claim 7
Dependent Claim
28 words
A structure as defined in claim 1, wherein said male coupling member is a sphere and further comprising resilient means urging said sphere into said female coupling member.
Claim 8
Dependent Claim
25 words
A structure as defined in claim 1, wherein said female coupling member is provided with at least one concave socket for said male coupling member.
Claim 9
Dependent Claim
25 words
A structure as defined in claim 1, wherein said female coupling member is provided wIth at least one trough-shaped socket for said male coupling member.
Claim 10
Dependent Claim
32 words
A structure as defined in claim 8, wherein said socket extends in parallelism with said axis. 10 A structure as defined in claim 8, wherein said socket extends radially of said axis.
Claim 11
Dependent Claim
21 words
A structure as defined in claim 1, wherein at least one of said coupling members is seperable from the respective portion.
Claim 12
Dependent Claim
35 words
A structure as defined in claim 11, wherein said one coupling member is said female coupling member and wherein said female coupling member is provided with at least one socket for said male coupling member.
Claim 13
Dependent Claim
32 words
A structure as defined in claim 1, wherein said female coupling member is a disc which is accommodated in said bore and shares angular movements of said driven portion about said axis.
Claim 14
Dependent Claim
28 words
A structure as defined in claim 1, wherein said female coupling member is an annulus arranged to share all angular movements of said driven portion about said axis.
Claim 15
Dependent Claim
43 words
A structure as defined in claim 1, wherein said driving element is a sheave and further comprising a first endless flexible element trained over and arranged to rotate said sheave and a second endless flexible element trained over and driven by said sheave.
Claim 16
Dependent Claim
36 words
A structure as defined in claim 1, wherein said driven portion comprises a hollow cylindrical load-engaging shell and a cap provided in one axial end of said shell said cap being formed with said axial bore.
