Abstract
Abstract A rotational power transmission connection for use in street sweepers to couple together driving and driven parts one of which is subject to abnormal rotative resistances, the parts having opposed conical surfaces one of which contains a deformed elastomeric ring engaging and capable of slippage on the opposing conical surface. The coupling has particular applicability for use in pairs to mount a replaceable broom core.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
56 words
In a street sweeper, a power transmitting coupling between rotationally driving and driven parts comprising inner and outer sections having opposed conical surfaces, and an elastomeric ring contained in an anNular recess in one of said surfaces and engaging the other surface and functioning to transmit rotational drive from one to the other of said sections.
Claim 2
Dependent Claim
56 words
In a street sweeper, a power transmitting coupling between rotationally driving and driven parts comprising inner and outer sections having opposed conical surfaces, and an elastomeric ring contained in an anNular recess in one of said surfaces and engaging the other surface and functioning to transmit rotational drive from one to the other of said sections.
Claim 3
Dependent Claim
23 words
A drive according to claim 1, including means for deforming said ring under variable radial compression permitted by clearance between said conical surfaces.
Claim 4
Dependent Claim
30 words
A drive according to claim 2, in which said ring is capable of slippage on the conical surface which it engages in response to relative rotational resistance between the sections.
Claim 5
Dependent Claim
30 words
A drive according to claim 2, in which said sections are axially relatively movable and adjustable, and stop means is provided to limit such movement and deformation of the ring.
Claim 6
Dependent Claim
31 words
A drive according to claim 2, including also a shaft extending within said inner section, and means carried by the shaft for adjustably varying said clearance and compression of the ring.
Claim 7
Dependent Claim
22 words
A drive according to claim 5, in which said means includes a bolt held against axial movement and threaded into said shaft.
