    • A simple and rugged sprinkler nozzle for use on an end portion of a length of tubing is disclosed. The sprinkler nozzle comprises a housing having: a tube end portion having a tube opening therein adapted to receive and be seated on the end portion of the length of tubing, said tub end portion additionally having a threaded cylindrical hole therein extending from outside the nozzle into the tube opening; an spray end portion having a lateral cut partially therethrough; a central portion having an internal path to conduct water fed from the tube in the tube end portion of the housing up to the lateral cut in the spray end portion of the housing; and, a set screw turned into the threaded cylindrical hole until tight against, and pinching the end portion of the tube thereby restricting flow therethrough and securing the sprinkler nozzle on the end portion of the tube. In the preferred embodiment a wear plug is inserted between the screw and the tube to protect the tube. The use of the set screw minimizes the probability of children making adjustments to the water flow. The sprinkler nozzle is ideal for use in planters, gardens along sidewalks, or any other location where a restricted and specific flow of water or chemical solution is desired.

    • 584,567. Thrust bearings. NAPIER & SON, Ltd., D., WILSON, J. K., and TOMKINSON, G. A. Jan. 2, 1945, No. 146. [Class 12 (i)] A ring for a thrust bearing comprises a solid steel annulus, which has a thickness substantially less than its radial width, and is coated with a thin layer of bearing metal over the whole of each of its two opposite faces. The bore may also be coated with the bearing metal, which may be a lead-bronze alloy, a leadcopper mixture or silver, and the ring may have a final coating of electrolytically deposited lead. A number of rings, A, may be coated simultaneously by placing them in a cylinder,F, spaced by rings G, introducing the bearing metal in a suitable form, such as swarf, and rotating the cylinder F in a furnace, so that the bearing metal is melted and deposited in the required thin layer on the opposite faces and inner edge of each ring A. When cool the rings are removed from the cylinder and the outer portions which are not coated, due to the thickness of the spacing rings G, are burred off. Alternatively, each ring may be packed in powdered metal and subjected to hydraulic pressure by which the metal is applied to the opposite faces of the ring. The ring may be used complete or in two or more segments, and oil grooves and depressions may be provided in its opposite faces.
