Abstract
Abstract A rotor assembly for a rotary drum type humidifier wherein two separate end members integrally formed of synthetic plastic material are mounted on a common shaft and each has a projecting circular row of fingers frictionally receiving the opposite ends of a resilient water pick-up annulus extending between the end members. The annulus may be removed from the assembly simply by removing a single spring metal fastener holding one of the end members on the shaft.

Claim 3
Dependent Claim
55 words
The rotor assembly defined in claim 1, wherein the non-rotatably connected one of said end members is longitudinally fixed on said shaft, the other end member is longitudinally displaceable along said shaft, and means is provided for releasably fixing said other end member on said shaft in any adjusted position of said other end member.
Claim 4
Dependent Claim
47 words
The rotor assembly defined in claim 2, wherein said other member is provided with a hub by which it is slidably mounted on said shaft, and said fixing means is a removable fastener mounted to be displaced along said shaft in axial holding relation with said hub.
Claim 5
Dependent Claim
59 words
The rotor assembly defined in claim 3, wherein said one end member is provided with a hub by which it is slidably mounted on said shaft, and there are cooperating means provided on said shaft and said hub for longitudinally fixing said one end member on said shaft and for connecting said one end member non-rotatably to said shaft.
Claim 6
Dependent Claim
62 words
The rotor assembly defined in claim 4, wherein said means longitudinally fixing said one end member on said shaft comprises a rigid projection on said shaft in axial abutment with a surface adjacent one end of the hub of said one end member and a removable fastener axially displaceably mounted on said shaft in abutment with the other end of said hub.
Claim 7
Dependent Claim
46 words
The rotor assembly defined in claim 4, wherein said shaft is a uniform diameter shaft having at the end where said one end member is mounted longitudinally spaced non-circular formations for connecting said shaft to said one end member and a motor driven coupling member respectively.
Claim 8
Dependent Claim
55 words
The rotor assembly defined in claim 2, wherein each of said end members is an integral hard synthetic plastic element having a row of circumferentially spaced rigid smooth surfaced fingers projecting within the adjacent open end of said annulus, said annulus having its opposite internal peripheral regions resiliently frictionally surrounding the respective rows of fingers.
Claim 9
Dependent Claim
30 words
The rotor assembly defined in claim 7, wherein said one end member is substantially imperforate and said other end member is open to passage of air longitudinally of said annulus.
Claim 10
Dependent Claim
44 words
The rotor assembly defined in claim 7, wherein said one end member is a substantially imperforate plate having said row of fingers projecting at right angles therefrom adjacent its outer periphery, and being formed centrally with a hub for sliding displacement along said shaft.
Claim 11
Dependent Claim
27 words
The rotor assembly defined in claim 9, wherein said hub is formed with a key slot for slidably interlock with a key formation on said shaft means.
Claim 12
Dependent Claim
51 words
The rotor assembly defined in claim 7, wherein said other end member comprises an annular plate from which said row of fingers project substantially at right angles, and is provided centrally with a hub slidably along said shaft and connected to said plate by a plurality of rigid but thin webs.
Claim 13
Dependent Claim
24 words
The rotor assembly defined in claim 1, wherein said fingers are substantially conical with a slight decreasing diameter toward the interior of the rotor.
Claim 14
Dependent Claim
36 words
The rotor assembly defined in claim 1, wherein said end members are relatively rigid integral synthetic plastic members having annular rows of circumferentially spaced smooth surfaced fingers projecting snugly within the adjacent end of said annulus.
Claim 15
Dependent Claim
47 words
The rotor assembly defined in claim 13, wherein the axially inner side of each end member is formed at the flange with an annular shoulder adjacent the row of fingers, the outer surfaces of said row of fingers lying substantially in the projected plane of said shoulder.
Claim 16
Dependent Claim
35 words
The rotor assembly defined in claim 13, wherein said fingers on each end member are solid projections of substantially the same length having transversely curved smooth surfaces at least on their outer annulus contacting regions.
