Stabilizer beams are provided within the retarder to maintain proper position and gage of the running rail The control system of the Model 50B retarder is illustrated in Figure 2 This system is hydraulically actuated pneumatically powered and electrically controlled A 4 way single solenoid pilot operated air valve located in the valve box permits air to pass to the accumulator and the pilot check valve Pressure in the accumulator forces hydraulic fluid through the pneumatically operated pilot check valve into the ram raising the ram to the normal closed retarder position see A Figure 1 When it is desired to release or open the retarder the 4 way air valve solenoid is energized see Figure 2 This action exhausts air to atmosphere thus removing air pressure from the accumulator and at the same applies air pressure to the pilot check valve opening a path to permit a return flow of hydraulic fluid back into the accumulator As the hydraulic fluid returns to the accumulator the ram is lowered to open the retarder see Figure 1 5796 B 2 UNION SWITCH amp SIGNAL NORMAL POSITION Retarder Closed No Car Present Ram is extended to close retarder Retarder rests on tie plate B RETARDING POSITION Retarder Closed Car Present Ram is extended Brake shoes are spread by the car wheel causing the retarder to rise from the tie plate The heavier the car the greater the retarding force exerted

NION SWITCH amp SIGNAL Page 37 37 37 37 40 5796 B p 1 4 gt UNION SWITCH amp SIGNAL SECTION I INTRODUCTION The Model 50B Air Assist car retarder has been developed by Union Switch amp Signal to fulfill the need for an inexpensive fast acting operable weight responsive retarder capable of handling 160 ton cars SECTION II DESCRIPTION AND OPERATION The Model 50B retarder applies a braking force to car wheels that is directly proportional to the weight of the car being retarded and therefore if all other conditions are the same removes approximately the same velocity head from all cars irrespective of weight The basic retarder consists essentially of a retarder unit and a unitized eontrol system The control system provides the means for operating the retarder unit to the open or closed position to apply full retardation or no retardation as desired see Figure 1 The retarder unit comprises two steel lever arms that are tie mounted on opposite sides of the running rail The inner ends of the lever arms are connected together by a through bolt that passes through the arms and a pair of brackets that engage and support the running rail The outer ends of the lever arms are pivotally supported by the tie mounted stool on one side and on the other side by the piston of the hydraulic ram Brake beams and shoes are bolted to the lever arms on either side of the running rails

S LUBRICATORS AND VALVES Supply Clean Lubricated Air An efficient filter and lubricator should be installed in the line supplying air to the equipment The filter should be a unit that will remove water and other contaminants in an air system Accumu lated liquid should be drained often from the filter If a portion of your system is in an area that does not get frequent routine maintenance or if there is considerable water in your air system you should consider a filter which drains itself automatically when its water level reaches a given point The lubricator used should deposit oil in the system at low air flow rates as well as at high air flow rates Proper lubrication is achieved when all moving parts in the air system are receiving enough oil to maintain a thin coat of high grade lubrication This is necessary to insure long life for the equipment Following is a list of air line lubricants we have found suitable E A Pacemaker 10 2 bd pA Rycon Industrial Oil 21 3 Mobil Oil Corp EE Almo 1 4 Mobil Oil Corp 222 22 Vectra Light 5 Mobil Oil Corp TM PEE NT DTE Light 6 Shell a Tellus 15 7 Standard Oil American Industrial Oil 15 8 Standard Oil Co 2 2 American Industrial Oil 21 9 Texaco eere Regal Oil A R amp O Generally speaking any light bodied mineral or petro leum base oil with a 180 F to 220 F aniline point and LITHO IM U S A i T MAINTE
