RAILWAY-S GNAL.

To allugboat iij'may concerm l I Be it known thatwe, JAMES J. COZZENS,

Referring now to the drawings forming part of, this specification, and in which like reference numeralsdesignate corresponding parts'of the. a paratus which is shown in one of its preerred terms-Figure 1 is a sectional plan view. Fig. 2 is a sectional elevation on the line 2-2 of Fig. 1, partly broken away. Fig. 3 is an exterior perspective view; Fi 4is. a detail viewin section taken on the l1ne'3--3 of Fig. 1.

Referring-now more particularly to the specific features as shown in the drawings, 1 is a casing having ;a glass face 2 through which the semaphore b1ade'3 is visible in its various positions against the background 4 at the front of the casing. The Semaphore blade 3 is fixed on arotary spindle 5 and gives its indications by changes in its )osition, and is therefore a position signal. (5 is an armature also fixed on said spindle and operatively associated with magnet 7 which, when energized, operates to turn the spindie and semaphore so that the latter occupies a vertical or clear position. Fixed on the spindle 5 is a spectacle 8 provided with colored glasses 9, 10 and 11, the same being respectively colored green, yellow and red for the indication of clear, caution and danger. The spectacle 8 extends out from the spindle 5 at right angles to the semaphore Patented Nov. 1, 1910.

3 so that when the spectacle isin its lower position, as shown in Figs. 1 and 2, the semaphore will be in danger-or horizontal position shown in Figs. 1 and 3. The background 4 is rovided with "an aperture 12.

.with which t e glasses of the spectacle respectively register.

13 is a lamp located behind the spectacle .and in register with the aperture 12. This lamp serves to illuminate the particular glass of the Spectacle which, at the time Being, is in register with the aperture 12.

The signal is provided with an electrically operated latch serving to engage and hold the signal in one of itspositions. 14 is this latch which consists of a spring retracted rod carried by the armature. 15 of the magnet 16. When the magnet 16 is energized,

its armature is drawn toward .the magnetand the latch 1 t is thereby thrown forward into the path of the lug 17 fixed to the spectacle 8, thereby arresting the movement of the semaphore and spectacle and holding them in one position of indication.

\Vhen the motor magnet 7 is energized and armature 6 is rotated with it, the spectaele and semaphore are moved from the danger to the clear position, 1n which the ,green glass 9 registers with the lamp and the aperture 12, and the semaphore is in vertical position. \Vhen the motor magnet 7 is deiinergized, the semaphore and spectacle move by gravity toward the danger position. I is"energizcd the latch 14 engages the lug 17 ll. however, the latch magnet 16 I and stops the signal at the intermediate or a caution position, in which the yellow glass 10 registers with the lamp and aperture 12,

and the semaphore occupies a position midway between the vertical and horizontal.

1S and 19 are stops to on age the lug 17 to arrest the movement of t e signal when it has reached the danger and clear positions.

20 is a door at the back of the casing.

The latch 14 is ehamfered on its back face, as shown, so that the latch may be pushed back by the lug 17in case the magnet 16,

is energized 'as the spectacle travels from danger to safety position. This prevents the latch from stopping the signal during this return niovcnu-nt.

The motor magnet; 7 and the latch magturn said armature and semaphore; an artificial background for said semaphore, having anaperture therein; a spectacle carried onsaid spindle behind said background and in register with said aperture; and a lamp behind, said spectacle.

2. In a railway signal, the combination of a semaphore'mounted on and arranged-to turn with a rotary splndle, and giving its 1 indications by changes in position; an armature fixed on said spmdle; a magnet associated with said ariiTlture and operating to turn said armature and semaphore; an artificial background for said semaphore, having an aperture therein; a spectacle carried on said spindle behind said background and in'register with said aperture; a lamp behind said spectacle; and an electrically operated latch arranged to engage and hold said'semaplrore in one'of its positions.

3. Ina-railway signal,-the combination of a semaphore mounted on and arranged to turn with a rotary spindle and adapted to occupy three, positions of indication, and giving itsindications by changes in posi; tion; an armature fixed on said spindle; a

magnet associated with said armature and operatmgto turn said armature and semaphore an artificial background for said semaphore; and an electrically operated latch arranged to enga and hold said semaphorjet 'in its interme iate position.

4. In ajiailwaysignal, the combination of a semaphore mounted on and arranged to turn With a rotary spindle and'adapted to occupy" three positions of indication, and giving its indicationsby changes in position; an armature fixed on said spindle; a magnet associated with said armature and operating to turn said armature and semaphore; an artificial background for said semaphore, having an aperture there1n; a

spectacle carried on said spindle behind,

said background and in register with said aperture; a lamp behind said spectacle; and an electrically operated latch arranged to engage and hold said semaphore in its intermediate position.

5. In a railway signal, the combination of a sema hore biased to danger and mounted on an arranged to turn with a rotary spindle, said semaphore giving its indications by changes in'-position-; an armature fixed on said splndle; a magnet associated with said armature and operating to .turn said armature and semaphore; an inclosing casing for said armature and magnet "and having an aperture in its front; a spectacle carried on said spindle within the casing and so as to register. with said aperture; a

lamp behind said spectacle; and an electrically 'operated latch to hold said sema-,.

phore in one of its positions. 6. In a railway signal, the combination of a semaphore biased to danger and mounted on and arranged to turn with a rotary; L

spindle, said semaphore being adapted to occupy three positions of indication and givngits lndicatlons by changes 1n posltlon; an armature fixed on said spindle; a. mag;

net associated with said armature and oper- V ating to-turn said armature and semaphore; an inc-losing casing for said armature and magnet and having an aperture in its front; a spectacle carried on said spindle within the casing and so'as to register with said aperture; a lamb behind said spectacle; and

anelectrically operated latch to hold said semaphore in its intermediate position In testimony whereoflwe have signed our names to this specification, in the presence of two subscribingwitnesse's.
