It is in this instance provided with a Kelkctor 15 in rear oJ the Lamp C, in order that as much of the linlit as is possible may b.- Uirown throu-h the Clrculat; •face plate I).

These numbers are secured to the baf by means of sleeves- one to each fiKure— the sleeve filtiivK the bar with sufficient accuracy to insure their retention m Shade.

Very many mbdifications of the devices which I have shown and dtscnlied mav be didc with- out departinK from the sjirit of mv invention : hence I do not wish to be conhntd to this pjeci3fe con. strucUon; nor.do 1 wishtobe confined to their use in connection with a head lightl as tjiey ma>s either in whole or in part, be used to advantage upon the various Signal Lamps em- ployed by railway employes.' ^ . , ^ , When it is desirable to exhibit different colours at different times from the same lamp, a^ ^ series of rollers with curtains of various colours may be employed, these rollers being arranged upon the same side of the lamp, or upon opposite sides, as convenience may dictate. ^, , , It will be seen from the above description that the Bar E, although made removable for the purpose of changing the numbers,' or fd|>ther purpose, yet so far as «ts me as a S.gna is concerned, Snd with reference to the curtain. itTs fixed, said curtain being removable at the w^i of the Engineer, , and only used when^casion requires ; whereas the nJinjbers are always in position, and always in sight, either with or without the curtain. » - • '^'' r ■ • : * / \ / ® r '' «) m ^,.
