Abstract
A railway signal having a housing, in which the housing has an annular ledge thereon. The annular ledge has first and second opposed surfaces. One or more portions of the second ledge surface, preferably cast raised bosses, are machined so as to have a selected height. A reflector is mounted upon the first ledge surface. Also attached to the signal housing is a lamp receptacle bracket. The lamp receptacle bracket has a first end that is mounted upon the one or more machined portions of the second ledge surface. The lamp receptacle bracket also has a second end that has a lamp receptacle attached thereto. An insulating plate is disposed between the lamp receptacle flat portion and the lamp receptacle bracket flat surface.
Claims21
A railway signal, comprising:
- a housing having first and second surfaces thereupon, wherein at least one portion of said second surface is machined so as to have a selected height;
- a reflector mounted upon said first surface, wherein said signal has a focal point in which a light source provided at said focal point is directed outward of said signal as a beam;
- and
- a lamp receptacle bracket having a first end and a second end, wherein said first end of said lamp receptacle bracket is mounted upon said at least one machined portion of said second surface, and wherein said second end of said lamp receptacle bracket has a lamp receptacle attached thereto and wherein said housing has a generally annular ledge thereon, and wherein said first surface of said housing is one generally annular surface of said ledge and said second surface of said housing is an opposite surface of said annular ledge.
