Abstract:
An adjustable stem drop apparatus and method for a fire extinguishing sprinkler mounted on a pipe located above the ceiling of a building and arranged in such a manner that the position of the sprinkler can be adjusted from below the ceiling after the ceiling has been permanently installed.
Abstract:
An adjustable mounting arrangement for hand-held shower heads includes a frusto-conical hose coupling, secured to the shower head, and a wall-mounted bracket in which the coupling is supported. The bracket includes opposed sidewalls containing a plurality of opposed pairs of channels of tapered arcuate crosssection such that each channel pair is capable of supporting the frusto-conical hose coupling. Each channel pair is oriented at a different angle relative to the vertical whereby the shower head is supported at a different angle by each channel pair. The hose coupling is rotatable, about its own longitudinal axis, within each support channel pair to provide additional positioned adjustment of the shower head. The front end of the bracket is opened to permit the hose to fit therethrough when the shower head is being placed in or removed from the bracket.
Abstract:
A side spray nozzle for connection to a water hose for delivering a fan-shaped spray including a nozzle head defining a radially extending discharge passage bordered by a pair of fanshaped lips defining a thin slot therebetween communicating with the discharge passage to cause the water issuing therethrough to assume a fan-shape. A spike is provided which is selectively positionable with respect to the nozzle head for selectively maintaining the angle of the slot therein when the spike is embedded in the ground.
Abstract:
The low-friction swivel joint in the hydraulic monitor has incorporated therein a worm wheel, the latter being rotated by a worm driven by a fluid motor. A second and corresponding swivel joint is also provided, being driven by fluid which is passed through the first-mentioned joint in order that there will be no twisting of pipes or conduits. The second joint effects rotation of a portion of the monitor about a horizontal axis, whereas the first-mentioned joint effects rotation of the monitor about a vertical axis.
Abstract:
This specification discloses a turret for fire fighting equipment capable of delivering a plurality of fire extinguishing agents onto a fire, characterized by having a plurality of nozzle means connected respectively with a plurality of separate conduit means; a single support means adapted for effecting any segment of rotation, including 360* and more of rotation for the turret; and a plurality of concentric mounting and sealing means within the single support means. The concentric mounting and sealing means are each connected with respective ones of said conduit means to carry the respective fire extinguishing agents without admixing thereof and without entanglement of the respective conduit means. Also disclosed are specific elements; such as, the stationary external jacket serving as the single support means; the rotatable head; the respective conduit means; the swivel joints serving as the mounting and sealing means; the twin nozzles; and the disengageable locking means for effecting unitary operation of the twin nozzles, or allowing them to be operated separately.
Abstract:
A spray assembly including a spray pipe with a bottom provided with a plurality of first through holes, each having a nozzle, wherein the nozzle includes a slider with an area larger than the first through hole, to cover the first through hole. The nozzle is connected to the slider and protrudes from the first through hole; the nozzle also includes a locking member to connect the slider to the spray pipe. The slider can move to adjust the position of the nozzle in the first through hole. There also provides a wet etching device including a spray unit, wherein the spray unit includes a plurality of spray assemblies as mentioned above, and a plurality of spray pipes in the plurality of spray assemblies are arranged in parallel with each other or approximately in parallel with each other.
Abstract:
A product applicator system for distributing a liquid product accurately using low volume applications which minimize the quantity of product used and ensures more accurate results. The product applicator system generally includes a housing which includes a removable inlet port mount and outlet port mount. The positioning of the inlet and outlet port mounts on the housing is interchangeable. Supply hoses provide a product to the inlet port mount where the product is traversed through internal conduits to exit the housing via oscillating and overlapping spray heads. An internal motor provides oscillating motion to the spray heads. A rotator assembly which includes a rotator motor may be utilized to orient the housing in horizontal, vertical, or various diagonal orientations. The housing is adapted to either connect to a vehicle, be positioned on a stationary or movable platform, or be connected to a boom using boom connectors.
