Abstract: 6246. Yates, J. R. March 14. Lubricators.-Relates to lubricators for engines, motors, and machinery in which the lubricant is expelled by a piston, such a type of lubricator being described in Specification No. 11.449, A.D. 1900. The body a, Fig. 1, of the lubricator may be mounted on springs s, carried by a frame b adapted to rotate about a vertical pivot c ; or the body a may be provided with a pivot turning in a spring-supported frame. The springs may be dispensed with, and the trunnions on the body may engage slots.in the frame, the body being mounted on a vertically-adjustable pivot supported by the frame. This construction compensates for inaccuracies in fitting, and relieves the lubricator and pipes from strain. In addition to, or in place of, these pivoted connections, the pipe connections may be arranged so as to allow relative movement of the parts. In the crank-pin lubricator shown in Fig. 5, the outlet tube d passes through a stuffing-box d' in the lubricator cylinder, and is received in a tubular pocket e, which may be fitted with an air valve e<1>. Perforations are formed in the tube for the passage of the lubricant. The tube d is connected to the horizontal member of a T-shaped junction g, the vertical members of which receive the feed pipe h, which is closed at the top and perforated for the passage of the lubricant from the pipe d. Stuffing-boxes h<1> are provided on the junction, so as to allow a vertical motion of the pipe h to compensate for inaccuracy in fitting. The pipes h, d rotate with the crank-pin, and the motion of the pipe d is transferred by a cam i and ratchet gearing to a worm shaft, which operates a nut in engagement with the screwed rod of the piston for forcing out the lubricant. In the case of a pedestal bearing for line shafts &c., the lubricator is fixed directly upon the pedestal, and at the lower end of the lubricator is fixed an arm for carrying a bracket supporting one end of a cam shaft for operating the lubricator piston. The other end of this shaft is carried in a bearing fixed to the lubricator cylinder, and the shaft is operated, by belt gearing, from the line shaft &c. Where the lubricator has a number of feeds, the bracket for supporting the cam shaft may be fixed upon one of the feed connections. In place of connecting the tube d directly with the lubricator, it may be connected to a standard provided with a pocket and stuffing-box, and coupled to the lubricator cylinder by a pipe. Where the lubricator is fitted to double-throw cranks, crosshead slippers, &c., a knuckle joint is provided in the supply pipe. In the arrangement shown in Fig. 9, the pipe d is connected to a casing n, in which is arranged a cage liner r held in place by a packed cover o. The L-shaped outlet q passes through a stuffing-box t, arranged between the liner and the casing n. A pivot or stud t<1> on the outlet is journalled in a bracket u. In a modification, the joint between the outlet and the casing is made by cup-leathers held in place by projections on the cover o.
