Abstract: A central hub includes a plate and a sleeve attached to the plate and adapted to receive a sprinkler head. The sleeve may be a telescoping sleeve. By providing a central hub with the plate and sleeve, the central hub provides increased stability and versatility to the sprinkler head. The plate provides additional stability and support to the sleeve, and thus the sprinkler head, rendering the combination better able to operate effectively when high fluid pressures are utilized. The central hub is generally attached to a support structure by some mechanism, such as a leg. The addition of the plate adds versatility by increasing the number and variety of legs that can be used to attach the central hub to the support structure.

Abstract: A support system for use in fire-protection sprinkler systems and for positioning and supporting a fire-protection sprinkler head in a suspended ceiling including a T-bar grid for supporting panels. The support system includes a hub defining an annular opening configured to receive the fire-protection sprinkler head, which is connected to a flexible conduit. A leg is attached to the hub and has first and second ends attached to the T-bar grid of the suspended ceiling.

Abstract: A fire suppression sprinkler system (10), and method for installing a sprinkler system (10)in new and existing buildings. The system includes a manifold (12) that supplies fire-suppression fluid to a set of wall-mounted sprinkler heads (14) via flexible sprinkler head conduits (16) through an unobstructed path (18). The installation and retrofit methods include determining the location of the sprinkler head (14), installing the manifold (12), making sure that there is an unobstructed path (18) between the manifold (12) and the sprinkler head location, running the conduit (16) through the path (18) by snaking it where necessary through the wall (50) to which the sprinkler head (14) is mounted, connecting the conduit (16) to the manifold (12) and sprinkler head (14), and then mounting the sprinkler head (14).

Abstract: A system is provided for maintaining a sprinkler head in a position to allow continued operation during a fire in the event that the support structure for the sprinkler head fails or is otherwise removed. The support system includes a central hub adapted to receive a sprinkler head, a first leg attached to the central hub and having first and second ends. The support system also includes first and second ends having fastening devices adapted to attach the ends to the support structure. The fastening devices are configured to break away from the support structure in the event of support structure failure.

Abstract: A support system for positioning a sprinkler head relative to a support structure in a ceiling, floor, or wall includes a central hub adapted to receive the sprinkler head, a first leg attached to the central hub and having a first end configured to be attached to the support structure, a second leg attached to the central hub and having a second end configured to be attached to the support structure, the second leg being spaced-apart from and substantially parallel to the first leg. The support system combines increased flexibility in installation with increased support for the sprinkler head during operation.

Abstract: A portable cleaning and flushing device for beverage conduits such as draft beer distribution coils includes a manifold, couplings and a number of valves which are controllable so as to sequence the supply of detergent from a reservoir, mixing with water from an external water source and flushing and rinsing of the distribution conduits. The device is wheeled about like a handcart and is coupleable to one or more beverage distribution lines by lead lines in place of normally attached kegs. The device is coupled to a water supply and to an electric power outlet. Detergent and pressurized water are mixed and flushed through the beverage conduit to an open spigot at the dispensing end. A preferably programmable computerized controller sequences the operation of valves for detergent addition to a manifold, venting of the manifold, water supply for obtaining a mixing solution, application of the mixing solution to the conduit, rinsing and finally draining.

Abstract: A relocatable sprinkler assemblage includes a flexible conduit connecting to a source of fire-suppression fluid, a heat-sensitive sprinkler head, a rigid fitting connecting the conduit to the sprinkler head, and a removable cap that, together with the fitting, creates a watertight compartment around the sprinkler head so that the assemblage can be moved while the sprinkler system remains pressurized and operational. The cap includes alerts the user to the condition of the sprinkler head, whether or not the head has been activated during the relocation process. In one embodiment, the cap is transparent, so that the condition can be determined by looking for fluid inside the cap. In another embodiment, the cap has a valve that can be operated manually to determine if there is fluid in the cap. In a third embodiment, the cap has a flexible bag that appears rigid if there is pressurized fluid in it.
