Abstract: A sprinkler of the impact drive type is constructed substantially of plastic and includes a separate cap which is snap-fit over a pair of upwardly extending legs from a sprinkler body to form a bridge for an impact mechanism window. Provision of the separate bridge-forming cap facilitates automated assembly of the sprinkler, and also allows protective bearing-surface shields to be formed integrally with other sprinkler components and positioned about critical wear regions of a fulcrum pin for pivotally supporting an impact drive arm. When a plastic fulcrum pin is used, these bearing-surface shields protect the pin from abrasives, such as dirt, which can otherwise become lodged between the pin and the drive arm to cause accelerated pin wear.

Abstract: An ultrahigh pressure water apparatus converts feed water of normal pressure into ultrahigh pressure water by means of an ultrahigh pressure pump and projects the ultrahigh pressure water through a nozzle gun in the form of jets of ultrahigh pressure water. The nozzle gun has an eccentric shaft tube rotatably disposed inside a nozzle cover, a high pressure hose rotatably inserted into the eccentric shaft tube, and nozzles fastened to the leading end of the high pressure hose. Owing to the rotation of the eccentric shaft tube, the jets of ultrahigh pressure water projected through the nozzle are sympathetically rotated.

Abstract: The invention relates to shower fittings especially those used in the paper and board making industries. The shower fitting incorporates at least one jet for directing on to a surface a jet of liquid which is suitable for cleaning and/or reconditioning the surface. The jet or jets are normally mounted in a tube to which the liquid is supplied and which is reciprocated across the surface to ensure that the entire width of the surface is treated and to avoid damage to the surface that might result if a jet of liquid is directed constantly at the same area of the surface. The invention is concerned with the problem of ensuring adequate support and protection for the tube. In one particular embodiment, the tube 1 is mounted for reciprocation inside a support tube 3. Support bushes 2 spaced along the axial length of the tube 1 ensure adequate support while protection is provided by the outer tube 3.

Abstract: Apparatus is provided for manipulating and controlling the movement of a tool, and specifically a spray gun, through a plurality of predetermined motions. The apparatus includes, in a preferred form, a rectangular frame having crossing supporting rods extending between opposite frame members. A mounting member is slidably mounted on crossing portions of the rods with the spray gun carried thereby. The spray gun is connected to the mounting member in a manner such that it can be moved toward and away from the mounting member in a direction perpendicular to the plane of the frame. The spray gun can also be pivotally moved on a first axis which is parallel to the plane of the frame and pivotally moved on a second axis which can also be parallel to the frame and perpendicular to the first axis. The connecting means also enables at least a spray head of the spray gun, if not the whole spray gun, to be pivotally moved about an axis which is perpendicular to one of the aforesaid two axes.
