The present invention provides an externally mounted assembly for supporting a rotatable shaft member driven by an electric motor. The externally mounted assembly comprises an annularly projected bearing support member disposed on a substantially vertical plane and a bearing member mounted on the bearing support member. Such bearing member is connectable with the rotatable shaft member for supporting such rotatable shaft member thereby reducing extraneous vertical and horizontal movement of such rotatable shaft member while permitting such rotatable shaft member to rotate freely.

The present invention provides an improved lubrication system for use in a railway locomotive brake valve. Such railway locomotive brake valve includes a suppression cam having a plurality of detented control positions. It further includes a handle connected to the suppression cam for moving the suppression cam to such plurality of detented control positions. There is a spring loaded latch mechanism for engaging the suppression cam and providing a positive stop for such plurality of detented positions. The latch mechanism is a cylindrically shaped member with an elongated convex shaped protrusion at one end for engaging the suppression cam. Such brake valve further includes a bushing surrounding and guiding such latch mechanism. Such improved lubrication system comprises a coating of a preselected low friction material applied to and dried on at least one of the latch mechanism, the bushing and the suppression cam.

165/047000, 417/243000

An air compressor and aftercooler combination in which the aftercooler is located in front of the air compressor. The aftercooler is connected to the air compressor for receiving hot, high pressure air and for effectively cooling the same such that the temperature of the high pressure air delivered by the aftercooler approaches that of atmospheric ambient. A fan is located to draw and direct atmospheric ambient air to the compressor and to and through aftercooler for effective cooling of the high pressure air in the aftercooler, as received from the compressor.

417243

A thermostatically controlled intercooler system for use with a multiple stage compressor to prevent the condensation of water from the compressed gas, such as air, within the system, whereby the temperature of a compressed gas entering a second compressor stage following the first compressor stage is controlled to a target temperature, ideally up to about 250. degree. F. , as will not allow the partial pressure of the water vapor therein to exceed the saturation vapor pressure associated with and defined by the temperature achieved by cooling the air prior to the air entering the subsequent compression stage.

Apparatus for rapidly exhausting air pressure from an intercooler pneumatically connected to receive compressed air from an air compressor. The apparatus includes a blowdown valve pneumatically connected to receive air pressure contained in the intercooler. The valve has a large exhaust port and a valve member seatable against the port to open and close the same. An inlet port is provided for admitting a compressor unload signal to the valve, with the unload signal being effective to move the valve member away from the large exhaust port to allow rapid exhaustion of intercooler air pressure to atmosphere through the exhaust port.

417243

An air supply system having a multi-cylinder, two-stage air compressor including a pair of low pressure cylinders and a high pressure cylinder. A first intercooler interconnected between the outlet of one of the pair of low pressure cylinders and the inlet of the high pressure cylinder and a second intercooler interconnected between the outlet of the other of the pair of low pressure cylinders. An aftercooler connected to the outlet of the high pressure cylinder for effectively reducing the temperature of the compressed air supplied to a storage reservoir to near or at ambient temperature. A protective housing including a frontal screened opening for permitting a rotary fan to draw cooling air into the housing and including an internal shroud for directing the cooling air over the intercoolers and aftercooler.

184 391

Apparatus for lubricating components in an air compressor having a crankcase for holding oil. The apparatus includes an oil pump located in the crankcase and oil, and a hollow plunger mechanically and hydraulically connected between the oil pump and an eccentric provided on a crankshaft of the air compressor. A filter for filtering the oil held in the crankcase is mounted on a block secured to an external surface of the crankcase. The block mounts the filter on the crankcase and in fluid communication with the pump such that filtered oil is directed to the hollow plunger from the pump after oil is directed into the pump from the filter and after oil is pumped from the crankcase and sent to the filter by the pump.
