Abstract: 16,348. McCanna, J. F. Aug. 14. Brakes.-Relates to means for lubricating the parts of a locomotive, described as applied to the cylinders and the air-compressing apparatus for the brakes. An oil reservoir 4, Figs. 1 and 2, is mounted on the front of the boiler and is connected by pipes 12, 13, 14 to pumps for supplying oil to the cylinders 1 and the air pump 2, 3. The oil for the air-pump steam cylinder 2 passes through the pipe 14 to one cylinder of a double pump 46 mounted in the cab and is discharged through a spring-controlled valve 24<1> into the steam pipe 49 which supplies steam to the cylinder. The oil for the air pump 3 passes from a separate reservoir 50 through a pipe 51 to the other cylinder of the pump 46. and is forced through a spring-controlled valve 24<11> into the air pipe 47 leading from the pump 3. The reservoir 4, Fig. 8, has a number of cross connections 55 attached to the base, the channel in each connection opening opposite to the lug in which the supply pipe 12, 13, or 14 is fixed. In the cross channel of each connection is telescopically mounted a fitting 59 to which a gauge glass 6, 7, or 8 is fitted. An aperture 64 is arranged opposite to an aperture 65 in this fitting, and normally these apertures register with the passage 56 and the supply tube. When it is required to ascertain the rate of feed of the lubricant, the fitting is pulled out, thereby closing the apertures 64, 65 and bringing an aperture 66 into line with the supply pipe. The oil is now supplied from the gauge glass, the case 63 of which is graduated, and the rate of supply can be ascertained. A screw takes into a slot in the fitting 59 to limit the motion. Figs. 9 and 10 show the pump for forcing the oil used in lubricating the air-compressing apparatus. On the casing 107 of the pump is mounted a cylinder 108 connected to the compressed-air pipe 47. A plunger 110 works within the cylinder and serves to operate a pivoted arm 113 controlled by a spring 115. The periodic compression of the air within the tube 47 operates the plunger and consequently the arm 113, the spring 115 bringing the arm and plunger back to the original position. The nut 118 controls the travel of the plunger. The rocking motion of the arm 113 is converted by a ratchet mechanism into a rotary motion of a shaft 114, the spring-pressed plunger 122 pressing against the ratchet-wheel to hold the same against accidental movement. On the shaft 144 is mounted a sleeve having an eccentric disc portion 127, which engages and operates a yoke 128 to which is secured a rod 129 carrying a crosshead 133 to engage the plungers 137 of the pumps. The stroke of the plungers is adjusted by means of the nuts 139. One pump is connected to the pipe 14 and the other is connected to the pipe 51. The inlet and outlet passages of the pumps are controlled by ball valves 150, 153. As the pumps are operated by the air in the pipe 47, the rate of feed of the oil is proportional to the speed of the air pump. The pump also serves to indicate whether the air pump is acting.
