Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
149 words
A nozzle for a fire fighter''s hose comprising a body having a cylindrical passageway with an end wall having an eccentrically disposed aperture therethrough, a rotatable cylindrical valve member fitted into the passageway and having slidable engagement with the end wall, the valve member having three or more bores therethrough opening into an end surface of the valve member and each of different diameter to the other bores the end surface of the valve member also having a blank part, the bore and the blank part being positioned to be brought, selectively, into register with the aperture upon rotation of the valve member in the passageway, a control ring embracing the valve body and a slot in the valve body beneath the control ring and a connector element between the control ring and the valve member so that rotation of the control ring causes rotation of the valve member.
Claim 2
Dependent Claim
149 words
A nozzle for a fire fighter''s hose comprising a body having a cylindrical passageway with an end wall having an eccentrically disposed aperture therethrough, a rotatable cylindrical valve member fitted into the passageway and having slidable engagement with the end wall, the valve member having three or more bores therethrough opening into an end surface of the valve member and each of different diameter to the other bores the end surface of the valve member also having a blank part, the bore and the blank part being positioned to be brought, selectively, into register with the aperture upon rotation of the valve member in the passageway, a control ring embracing the valve body and a slot in the valve body beneath the control ring and a connector element between the control ring and the valve member so that rotation of the control ring causes rotation of the valve member.
Claim 3
Dependent Claim
32 words
A nozzle as claimed in claim 1 in which the bores are close to each other so that each of two adjacent bores can be brought partly into register with the aperture.
Claim 4
Dependent Claim
40 words
A nozzle as claimed in claim 1 in which a small pressure space is formed between the end wall and the valve member, with which the bores through the valve member communicate to relieve the pressure on the valve member.
Claim 5
Dependent Claim
57 words
A nozzle as claimed in claim 1 in which the valve member has sliding contact with a slightly raised portion of the end wall around the aperture and is spaced from the remainder of the end wall to define with that end wall a pressure space to relieve the pressure between the valve member and end wall.
Claim 6
Dependent Claim
45 words
A nozzle as claimed in claim 1 in which the valve member has sliding contact with a central region of the end wall and is slightly spaced from the end wall over the remaining area of that end wall to define a small pressure space.
Claim 7
Dependent Claim
94 words
A fire fighter''s hose nozzle comprising a body having a cylindrical passageway and an end wall having an eccentrically disposed aperture communicating with that passageway, and rotatable cylindrical valve member fitted into the passageway having sliding engagement with the end wall, the valve member having at least two bores therethrough of different diameters positioned to be brought, selectively, into register with the aperture upon rotation of the valve member in the passageway, said body having an arcuate slot communicating with the passageway and a control member connected to the valve member through the slot.
Claim 8
Dependent Claim
94 words
A fire fighter''s hose nozzle comprising a body having a cylindrical passageway and an end wall having an eccentrically disposed aperture communicating with that passageway, and rotatable cylindrical valve member fitted into the passageway having sliding engagement with the end wall, the valve member having at least two bores therethrough of different diameters positioned to be brought, selectively, into register with the aperture upon rotation of the valve member in the passageway, said body having an arcuate slot communicating with the passageway and a control member connected to the valve member through the slot.
Claim 9
Dependent Claim
30 words
A nozzle as claimed in claim 6 in which said control member comprises a ring embracing the body member with a connector element between the ring and the valve member.
Claim 10
Dependent Claim
26 words
A nozzle as claimed in claim 7 having sealing means between the valve member and the body to prevent the ingress of water to the slot.
Claim 11
Dependent Claim
26 words
A nozzle as claimed in claim 6 having sealing means between the valve member and the body to prevent the ingress of water to the slot.
