To all'whom it mag/concern j a WinnER GqANDnn- SON and FRED F. COSLE'FI," citizens of the United States, residing at-Dennison, 1n the county of Clark and State of Illinois, have invented certain new anduseful Improvements in Railroad-Signals; of which the following is a specification.

. Our invention relates to improvements in railroad signals, the ob ectof theinvention being to provide an improved arrangement of signals in connection with improved means. for. operating andhousing them, whereby the signals are readily operative and can be used with equalefficiency either night or day for signaling in one or both directions. 1 a

A further object is to; provide .an improved construction of housing with im-: proved signals movable into; and out of the housing, and provide a lamp having pivoted blinds, the blinds beingliftedibylthe signals,

sothat atnight the signals are illuminated whenever moved to signaling position. p

With these and other objects in view,the invention :conslsts in .;CQIt1f1I1' novelqfeatures of construction and combinations and ar-' rangements of parts as will be more fully;

hereinafter described and pointed out in the claims. 3

In the accompanying drawings: Figure 1 is a view in elevation partly broken away illustrating our improvements. Fig.2 is a view in vertical sectionon theline 22 of Fig. .4, showing the signal n housed position. Fig. 3 is a 811111131 view showing the signal in signaling position. Fig. 4; is a view in front elevation of the signaling? mechanism. Fig.y5 is a view in transverse section on the line5- 5 of Fig. 4:. Figs. 6 and 7 are views in elevation illustrating two of the signals. Fig. 8 is a view partly in section and partly in elevation illustrating one of the signal operating levers- Fig. 9

is a view in elevation ,at right angles to Fig. 8, illustrating theseries of signaling levers, and Fig. 10 is a view partly in elevation: and partly broken, away illustrating amodification. a

1 represents a signal post, and 2 a tower. On. the post 1, we support our improved signal housing 3 by means of brackets 4 securedto the lower endsof the housing,

and to the post.

The housing 3 is ofygeneral .U- shape in Specification of Letters Patent. Patnted Oct, 6,1914. Application filed June 2, 914. Seria1No. j8 42,3 97.

cross section, that is to say, its rear wall is bent inwardly in general rectangular form as indicated at 5 to form arecess for :the IICCOIIll'llOCliItlOIl oi the post 1, and this inwardly bent portion 5 divides the housing a into two signaling

compartments

6, 6, i at opposite sides of the post and the full width of the housing,so as to provide ample space at the sides of the post for the accommodat on of the

signals

7 and 8, two signals being provided at each side.

The front 9 of the housing 3, is provided with slots 10, through which the

signals

7 and 8 are movable, and the outer edges of said signals have flanges 11 whichcover the slots when the signals are in closed POSllilOIli and exclude the weather. y

The signals are all pivotallysupported upon a pin 12through the upper forward corner of the housing, and each signal is 5 provided on its outer flanged edge with an eye 13 connected by a link 14: with one end of a bell-crank-lever 15.

. The bell-crank-levers 15 are supported on brackets 16 secured to the top of the housing 3, and each bell-crank-lever is connected by a rod 17 with an operating lever 18. The

rods 17- are provided between their ends with turn buckles 19 to permit. adj ustment as dee sired. y a a 1 The levers 18 are provided with detents 20 to engage in notched segments 21 so as to hold; the lever at its different positions. As

it is ordinarily necessary to have but two.

positions of the lever, we have shown each segment as hELVlIlgYtWO notches.

Abracket 22 is secured to the forward faceof the housing 3 about midway between its ends and between the pairs of signals 7 andS. Thisbracket 22 supports a lamp 23? which is provided, with lenses 24 at both sides. These lenses 24 are normally covered:

by blinds 25, both blinds being pivotally connected at their upper inner corners by a pin 26, secured to a fixed part of the housing.

.Eachl blind, at its lower outer corner, is providedwith a laterally projecting finger 27 in position to be engaged by the outer edges of the

signals

7 and 8, so that when i the signals are moved to signaling position, they. will lift the blinds and permit the light from the lamp to. illuminate the transparent portions 28 of the signals. The lamp, of

course, is utilized only at night and the sig: rials are of different colors with transparent which, as the signals begin-to move down-- wardly, exert a pull on the fingers 27 and start said blinds in a downward direction,

the blinds completing their downward movement by gravity.

As the

fingers

27 and 29 are yielding or elastic, there is no danger of an interlock of the parts at any time, but the fingers 29 are so located that they will be positioned above the fingers 27 when the parts are in signaling position as shown clearly in Fig. 3. However, under ordinary conditions, the parts will swing freely by gravity and the fingers are provided to prevent any possibility of the blinds remaining in an upward position.

In the modification illustrated in Fig. 10, the housing 3 is secured by brackets 30 directly to the tower 31, dispensing with any posts for supporting the housing, and in this modification the operating levers 32, corresponding to levers 18, are supported upon segments 34 on the wall of the tower, rather than upon a platform, as indicated in the preferred form.

The operation is as follows: When a train is approaching the signal station, the operator swings the proper lever 18 to move either

signal

7 or 8 into a horizontal position, drawing the'said signal out of the housing, and as the latter moves upwardly, it raises the blind 25. If the lamp is lighted, it will illuminate the signal, and a lighted lamp is always in place at. night. When the signal is moved downwardly, it is moved into the housing and the flanged outer edges of the signal will keep out the weather. The levers '18 operate not only to lift the signals, but to force them into the housings and to lock them in the housings, so that the housing becomes weather tight.

Various slight changes might be made in the general form and arrangement'of parts described without departing from our invention, and hence we do not limit ourselves to the precise details set forth, but consider ourselves at liberty o make such changes and alterations as fairly fall within the spirit and scope of the appended claims.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent is: 1. A railroad signal comprising a housing having slots therein, of signals pivotallyv supported in the housing and movable through the slots, said signals having flanged outer edges adapted to close the slots, means for drawing the signals out of the housing, and said means adapted to force the signals into the housing and hold the flanged edges against the outerface of the housing, substantially asdescribed.

2. A railroad signal comprising a housing having slots therein, of signals pivotally .supported .in the housing and movable through the slots, said signals having flanged outer edges adapted to close the slots, bell-crank-levers supported on the housing, links connecting the bell-crank-. levers with. the signals, operating levers, and rods connecting the bell-crank-levers with the operating levers, said operating levers having means for locking thesame in position to hold the signals in the casing and out of the casing in signaling position, substantially as described.

3. A railroad signal, comprising a housing having slots in its wall, signals pivotally supported in the housing and movable through the slots, a lamp support secured to the housing between the slots, pivoted blinds at opposite sides of the lamp support, and means compelling the movement of the blinds when the signals are moved to signaling position, substantially as described.

4:. A railroad signal, comprising a housing having slots in its wall, signals pivotally supported in the housing and movable through the slots, a lamp support secured to the housing between the slots, pivoted blinds at opposite sides of the lamp support, and fingers projecting laterally from the blinds in position to be engaged by the signals when thelatter are drawn to signaling position,

whereby the blinds "are elevated when the signals are thus moved, substantially as described.

5. A rallroad slgnal, comprlslng a housing having slots in its wall, signals pivotallysupported in the housing and movable through the slots, a lamp support secured to the housing between the slots, pivoted blinds at opposite sides of the lamp support, laterally projecting fingers on the blinds adapted to be engaged by the edges of the. signals to 1 lift the blinds when the signals are moved to i signaling position, and fingers on the signals adapted to engage the first-mentioned fingers and force the blinds downwardly when the signals are lowered, substantially as described.

' 6. A railroad signal, comprising a housing, a lamp supported on the housing, signals in the housing pivotally supported and movable through the housing at opposite sides of the lamp, said lamp having lenses in opposite sides, pivotally supported blinds at opposite sides of the lamps, said signals having transparent portions therein corresponding in color to the color of the signals, and means compelling the blinds to move when the signals are moved to illuminate the signals when the latter are moved to signaling position, substantially as described.
