Abstract
Abstract A discharge head and a fire protection system incorporating the head in which the head is in the form of a body member having an inlet adapted for connection to a source of fluid and an outlet for directly discharging the fluid in a solid conical spray pattern. A curved deflector plate cooperates with the outlet of the head for intercepting a portion of the spray and forming an additional discharge pattern.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
104 words
A fire protection system for buildings and the like comprising a plurality of extinguishant discharge heads located in the space to be protected, means for connecting said heads to a source of extinguishant, each of said heads having an outlet for discharging a spray of said extinguishant in a pattern of a generally solid circuit cross-section, means supported by said heads for intercepting the outer peripheral portion of the respective sprays from said heads and directing said portions outwardly from their respective sprays, the remaining portions of each of said sprays being allowed to discharge directly towards a predetermined assigned area in said space.
Claim 2
Dependent Claim
104 words
A fire protection system for buildings and the like comprising a plurality of extinguishant discharge heads located in the space to be protected, means for connecting said heads to a source of extinguishant, each of said heads having an outlet for discharging a spray of said extinguishant in a pattern of a generally solid circuit cross-section, means supported by said heads for intercepting the outer peripheral portion of the respective sprays from said heads and directing said portions outwardly from their respective sprays, the remaining portions of each of said sprays being allowed to discharge directly towards a predetermined assigned area in said space.
Claim 3
Dependent Claim
18 words
The system of claim 1 wherein said sprays from said outlets are discharged in solid conical spray patterns.
Claim 4
Dependent Claim
31 words
The system of claim 1 wherein said outlets are normally closed and further comprising control means automatically responsive to a fire in said space for controlling the opening of said outlets.
Claim 5
Dependent Claim
27 words
The system of claim 1 wherein said intercepting means are adjustably mounted relative to their respective heads to enable said portions of said sprays to be varied.
Claim 6
Dependent Claim
26 words
The system of claim 1 further comprising means responsive to variations in a predetermined condition of said system for varying the amounts of said intercepted sprays.
Claim 7
Dependent Claim
21 words
The system of claim 5 wherein said predetermined condition of said system is the extinguishant pressure at each of said heads.
Claim 8
Dependent Claim
26 words
The system of claim 1 wherein said intercepting means directs said intercepted sprays in a substantially radial direction relative to said remaining portions of said sprays.
Claim 9
Dependent Claim
26 words
The system of claim 1 wherein said intercepting means directs said intercepted sprays in a direction substantially opposite that of said remaining portion of said sprays.
Claim 10
Dependent Claim
102 words
A discharge head comprising a body member having an inlet adapted for connection to a source of fluid and an outlet for discharging a spray of said fluid in a pattern of a generally solid circular cross-section, and means supported by said body member for intercepting the outer peripheral portion of said spray and directing said portion outwardly from the remaining portion of said spray and towards an assigned area a predetermined distance from said body member, said remaining portion of said spray being allowed to discharge directly and unimpeded towards said area to provide a continuous spray pattern across said area.
Claim 11
Dependent Claim
102 words
A discharge head comprising a body member having an inlet adapted for connection to a source of fluid and an outlet for discharging a spray of said fluid in a pattern of a generally solid circular cross-section, and means supported by said body member for intercepting the outer peripheral portion of said spray and directing said portion outwardly from the remaining portion of said spray and towards an assigned area a predetermined distance from said body member, said remaining portion of said spray being allowed to discharge directly and unimpeded towards said area to provide a continuous spray pattern across said area.
Claim 12
Dependent Claim
19 words
The head of claim 9 wherein said spray is discharged from said outlet in a solid conical spray pattern.
Claim 13
Dependent Claim
36 words
The head of claim 9 wherein said outlet is normally closed and further comprising control means automatically responsive to a predetermined temperature in the vicinity of said body member for controlling the opening of said outlet.
Claim 14
Dependent Claim
28 words
The head of claim 9 wherein said intercepting means is adjustably mounted relative to said body member to enable the amount of the intercepted spray to be varied.
Claim 15
Dependent Claim
26 words
The head of claim 9 further comprising means responsive to variations in the fluid pressure in said head for varying the amount of said intercepted spray.
Claim 16
Dependent Claim
26 words
The head of claim 9 wherein said intercepting means directs said intercepted spray in a substantially radial direction relative to said remaining portion of said spray.
