Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
101 words
A fire fighting turret, comprising: a. a main body having a conical recess, b. a plurality of nozzles extending from the main body and clustered about the axis of the conical recess, c. a plurality of primary openings into the conical recess, each connected to a nozzle, d. a cup-shaped selector member having a conical surface concentric with and in coNtact with the conical recess of the main body and rotatable relative thereto about the said axis, the selector having at least one secondary opening therethrough arranged for selective alignment on occasion with one or the other of the primary openings.
Claim 2
Dependent Claim
101 words
A fire fighting turret, comprising: a. a main body having a conical recess, b. a plurality of nozzles extending from the main body and clustered about the axis of the conical recess, c. a plurality of primary openings into the conical recess, each connected to a nozzle, d. a cup-shaped selector member having a conical surface concentric with and in coNtact with the conical recess of the main body and rotatable relative thereto about the said axis, the selector having at least one secondary opening therethrough arranged for selective alignment on occasion with one or the other of the primary openings.
Claim 3
Dependent Claim
41 words
A fire fighting turret as recited in claim 1, wherein the primary openings lie on a circle which is concentric with the said axis, and wherein the primary openings are located at four of five positions equally spaced on the circle.
Claim 4
Dependent Claim
58 words
A fire fighting turret as recited in claim 2, wherein the secondary openings lie on a circle which is concentric with the said axis and which is the same size as the circle on which the primary openings lie, and wherein the secondary openings are located at two adjacent positions of five positions equally spaced on the circle.
Claim 5
Dependent Claim
55 words
A fire fighting turret as recited in claim 1, wherein the said conical surface of the selector member is convex, and wherein the selector member is also provided with a concave conical surface concentric with the convex conical surface, these two conical surfaces defining between them a thin wall through which the secondary openings pass.
Claim 6
Dependent Claim
60 words
A fire fighting turret as recited in claim 4, wherein the selector member is fixedly mounted on a rotatable shaft having one end rotatably carried at the apex of the conical recess of the main body, the other end of the shaft being provided with a position indicator to show the relationship of the secondary openings to the primary openings.
Claim 7
Dependent Claim
34 words
A fire fighting turret as recited in claim 1, wherein at least one of the nozzles is designed to carry one medium, and another one of the nozzles is designed to carry another medium.
Claim 8
Dependent Claim
44 words
A fire fighting turret as recited in claim 6, wherein a plurality of nozzles are designed to carry water and an equal number of nozzles are designed to carry a foam mixture, and wherein each primary opening is connected to one of the nozzles.
Claim 9
Dependent Claim
100 words
A fire fighting turret as recited in claim 7, wherein a number of positions are equally spaced on a circle on the conical recess concentric with the axis, wherein the number of positions is one greater than the number of nozzles, wherein the same number of positions are equally spaced on a circle of the same size on the conical surface also concentric with the axis, wherein each nozzle is connected to a primary opening, and wherein the number of secondary openings is equal to the number of nozzles divided by two and they are located in immediately adjacent positions.
Claim 10
Dependent Claim
48 words
A fire fighting turret as recited in claim 8, wherein the main body is fastened to a hollow connector member which is hingedly attached to a base member, and wherein a counterbalance means is provided to hold the main body, connector member, and nozzles in a predetermined aspect.
Claim 11
Dependent Claim
135 words
A fire fighting turret, comprising: a. a main body having a surface of revolution, b. a plurality of nozzles extending from the main body and clustered about the axis of the surface, c. a plurality of primary openings into the surface, each connected to a nozzle, d. a selector member having a surface of revolution concentric with and in contact with the said surface of the main body and rotatable relative thereto about the said axis, the selector having a pair of secondary openings therethrough arranged for selective alignment on occasion with at least one of the primary openings, the primary openings lying on a circle which is concentric with the said axis, the primary openings being arranged in pairs, each pair having the same spacing as the pair of secondary openings in the selector.
Claim 12
Dependent Claim
135 words
A fire fighting turret, comprising: a. a main body having a surface of revolution, b. a plurality of nozzles extending from the main body and clustered about the axis of the surface, c. a plurality of primary openings into the surface, each connected to a nozzle, d. a selector member having a surface of revolution concentric with and in contact with the said surface of the main body and rotatable relative thereto about the said axis, the selector having a pair of secondary openings therethrough arranged for selective alignment on occasion with at least one of the primary openings, the primary openings lying on a circle which is concentric with the said axis, the primary openings being arranged in pairs, each pair having the same spacing as the pair of secondary openings in the selector.
Claim 13
Dependent Claim
33 words
A fire fighting turret as recited in claim 10, wherein the space between adjacent pairs of primary openings is greater than the space between the openings of the said pair of secondary openings.
