## Abstract

A high speed, horizontal discharge hazard suppression device for preventing fire and explosions in confined zones such as dust collectors is provided which includes a tank having a generally arcuate tubular elbow extending from the underside thereof, and a selectively operable rupture disc mounted at the end of the elbow remote from the tank. The tank and elbow contain a desired fluid suppressant, and the device is mounted in an upright relation such that the suppressant bears directly against the rupture disc. The device serves to deliver suppressant in reduced time as compared with prior horizontal discharge units, and completely eliminates the costly and inefficient delivery pipe usually provided downstream of the rupture disc.

## Claims

### Claim 1

A horizontal discharge hazard suppression assembly, comprising:
a tank for holding a pressurized hazard suppression material and having a lower outlet;
an elongated, gently arcuate tubular elbow operatively secured to said tank outlet and in open communication with the interior of said tank;
a selectively operable, rupturable disc;
means mounting said disc in closing relationship to said elbow and adjacent the outlet end of said elbow remote from said tank;
structure for mounting said tank and elbow adjacent a zone to be protected from hazard, with said tank being generally upright and said outlet end of said elbow being oriented generally horizontally, such that said material is disposed within said tank and elbow and bears directly against said disc; and
means for rupturing said disc in response to the presence of a preselected hazardous condition within said zone such that said material flows directly from said outlet end of said elbow into said zone.

### Claim 2 (depends on 1)

The assembly as set forth in claim 1, said elbow extending through an arc of about 90 degrees.

### Claim 3 (depends on 1)

The assembly as set forth in claim 1, said disc rupturing means comprising an explosive element operatively coupled and extending into the interior of said elbow.

### Claim 4 (depends on 1)

The assembly as set forth in claim 1, said disc mounting means including structure for supporting said disc in spaced relationship to said outlet end of said elbow.

### Claim 5 (depends on 1)

The assembly as set forth in claim 1, including an apertured material-dispersing head operatively coupled proximal to said outlet end of said elbow and extending into said zone.

### Claim 6 (depends on 1)

The assembly as set forth in claim 1, said mounting structure for said tank and elbow comprising flange means secured to said elbow, and connector means for securing said flange means to a defining wall of said zone, said wall being apertured for flow of said material from said elbow and into said zone.
