To all whom 't'may concern:

4 Be it known that I, VINTHROP K.` Howe, a citizen of the United States, and resident of Rochester, in the county of Monroe andy Stateof New York, have invented'A certain provide an elcient signal, inwhich whenv two lights are displayed therein and oneliht' isextinguished for some cause, the' e ect of the lost.

In the drawings z--Figurel isafrontA eleuse oftwo lights is not wholly vation of avv signal mechanism embodying this invention, part of the casing,- being broken away to exhibit'- interior. const/ruction Fig. 2 is a verticalsect-ion onl theline. y

interior construction; Fig." L is a" rear elevation offthe lower part ofthe device, the rear. door being rem'o'ved `in order toshow interior: construction; Fig. 5 is across sectionthrough'. .the clutch.

The casing is adapted'to be made of cast iron, andis composed of a. mainiportion l` open at the front and back, and.` having` the vertical' web 0r` partitionA 2` substantialli'.` in the middle thereof, and also'the upwardly extending portion 3. Aconcavelfrontl plate" 4 covers the upwardly extendingportion, 3,`

and also the llower chamber'orx part, offf the casing, and is provided with two

lazedopenings

5 and 6. Alower opening-'7'. inthe;r

plate 4' may beprovided,ifi desired, andamayv contain a glass plate to permitlthe inspection'- of the interior without removing; thee. fronti plate 4. VThe back` plate 8i coyers-.thefrenr open end ofthe casing 1, andmay befprnvided with an o ningr and aglass. plate-9,-

in order to pernnt inspection of the interior at will. The'upward extensionfS'oflthecas-y ing 1 has glass openings` registering"withy the openings r5 .and 6. Oneoffthese openingsy 10 is shown in Fig. 3. ThereA is,thereiore a space inclosedin the: upwardfy extension of the casing-1 betweenrthe front -platelland said extension, throughwhichlight maypass..` Behind each of the'pairs.. of openingsisfw suitable light, shown in thepresentcase asfan.
