The side edges of the grille are conconnected together and form a unitary strucnected. together at H. Reinforcing and spacing flector units 20, and bottom II with ring 29 and bolts 3| mounted therein form another unit, and that these units and the coupling 3235 may be easily assembled by fastening the nuts 3'! on bolts 3| to adjustably connect the housing and coupling, and by fastening the nut 4| on the rod 38 to rigidly connect the top with its protecting grille in position on the housing.

An advantage of the construction described is the ease of assembling the parts and the fact that the interior of the signal is readily accessible by the removal of the single nut 4| which permits the top 12 and connected grille to be lifted from the top of the housing.

It will be understood that the lens 2| of one reflector unit 28 will usually be of a color indi-' cating that the track is clear, and the lens or lenses at right angles thereto (assuming the housing is a four sided one) will be of a different color to indicate danger. The imperforate parts I6 of the grille walls l5 function as ray confiners so that rays which may be reflected from one reflector unit are not visible to oneobserving another reflector unit. The grille Walls protect the reflector units against breakage Without interfering with the efliciency of the reflector units for their intended purposes.

Changes may be made in details of construction without departing from the scope of my invention and I do not intend to be limited to the exact form shown and described, except as set forth in the appended claims.

I claim:-

1. A reflector type signal comprising a plurality of side walls forming an open-top housing, each side wall having a reflector mounted therein, a top wall removably seated on the upper edge of said housing and extending beyond the side walls thereof, a grille connected to the edges of the top wall and suspended therefrom in spaced relation to said side walls and reflectors, whereby said top wall and grille'may be removed as a unit for gaining access to said reflectors.

2. A reflector type signal comprising a plurality of side walls forming an open-top housing, each side wall having a reflector mounted therein, a top wall removably'seated on .the 7 upper edge of said housing and extending beyond the side walls thereof, a grille connected to the edges of the top wall and suspended therefrom in spaced relation to said side walls and reflectors, said grille comprising an integral piece of metal having grille-like portions located opposite said reflectors and imperforate sections located at each corner between said grille-like portions.

3. A reflector type signal comprising a plurality of side walls forming an open-top housing, each side wall having a reflector mounted therein, a top wall removably seated on the upper edge of said housing and extending beyond the side walls thereof, said top wall having wall portions connected together at right angles depending from the edges of the top wall to enclose said housing in laterally spaced relation thereto, a section of each of said wall portions opposite a reflector being perforated to form a protecting grille therefor.

4. A reflector type signal comprising a plurality of side walls forming an open-top housing, each side wall having a reflector mounted therein, a top wall removably seated on the upper edge of said housing and extending beyond the side walls thereof, said top wall having wall portions connected together at right angles depending from the edges of the top Wall to enclose said housing in laterally spaced relation thereto, a section of each of said wall portions opposite a reflector being perforated to form a protecting grille therefor, said protecting grille having imperforate corner sections between said perforated sections.

5. A reflector type signal comprising a plurality of side walls forming an-open-top housing, each side Wall having a reflector mounted therein, a top wall removably seated on the upper edge of said housing and extending beyond the side walls thereof, a grille connected to the edges of the top wall and suspended therefrom in spaced relation to said side walls and reflectors, said housing having a bottom wall, a ring resting on said bottom wall 'within the housing, a coupling having a flange supporting the housing, said flange having spaced slots therein, bolts passing through said ring, bottom wall and slots for mounting the housing on said coupling.
