f @f i ATTORNEYS `latentecl vJuly l, 1930 .f'Thisjinvention relates to certain new and -useiul 4i mprovements in railway signal lmecheanismfandhas forgits Prmeryfobiet t give both audible and visual signalsgtotheengi- .116er :Offa ,Y tra-nr the'fevellt EOltre;railway YSvvitchgbeillaaelentally @P611 and the train shifting to a siding rather than travelling on a straight line, while an audible signal is given in the switchmans house or tower i so that proper provision can be made for stopping the train or swltchmg the-same onto v the mainline. l

A `further object of the invention is to provide a railway signal mechanism of the above. type wherein the car ,or train is equipped with a'novel construction of trolley pole'arms adapted to beengaged with spaced wires disposed above the track siding foruclosing a vcircuit to give ay signal in the car or train and Vin the switchmans house when the train has been accidentally switched fromjaxmain line to sidingl Y Y With the above and other objects in view that will become apparent as the nature of the invention is betterunderstood, the same consists in the novel form, combination and arrangement of partshereinafter more fully described, shown in the accompanying drawings and claimed.
