IMPROVEMNT IN RAILWAY-CAR SIGNALS.

. The Schedule referred to in these Letters Platent and making part o1 the same. f

To all whom it 'may con-cern,.-

Figure 1 is a view of the rear ot' a car with nur iinprovements attached.

Figure 2 is a top view of a ear with our improve-A ments attached.

Figure 3 is a side `view of the rear standard and its double crank-lever attacliment.

Figure 4 is a sectional view of the axle, showing the screw-threads eut thereon and the cog-wheel.

Figure 5 is a top view of the crank-wheel, its pawls, and the double crank-lever.

n `Our invention'hasfor its object the arrangement of blinds or blinkers, both in front and in rear of the signal-lights ou the top of railroad cars, in such manner thatthe engineer in charge of the train, as well as the engineer in charge of a following train, can always be informed whether a car has become unconpled and is moving backward, or whether any accident has happened by which aportion of the train has been stopped. These signal-lights are so secured on checar that a steady and uniform light is always emitted.

The nature of our invention consists in passing, ver- `,tically, through the body of the cara spindle, to the idowerV end of which, and beneath the car, is firmly sc feux-ed a cog-wheel. This wheel meshes in and gears with a screw-thread, cut on the rear axle of the car. On the upper end ot' this spindle, and ontop of the car, is firmly secured a crank-wheel, kto which are attached, near its periphery, two crank-arms. The other end of these crank-arms is secured to the handle ,of the blinds that cover the stationary lights on -each side of the car. These arms are so arranged on the crankwheel that when one b lind'is opened the other is closed. O'r, if preferred, `these handles may be dispensed with and the crank-arms attached directly to thc4 blinds or blinkers.

Our invention also consists in' pivoting to the circumference of thecrank-whcel, and ou opposite side-s of the same, two pawls. These pawls are so arranged that, when the car moves backward, they will catch in andlift one arm of a double crank-lever. The other arm of this double crank-lever works in a slot cut in a lever which is piveted to the front of the rear standard. This slotted Ieverls so connected, with a short Vother `in thc rear of the light'c.

lever on the rear side of the standard, that, when the car moves backward, the short lever, through its connections,vcauses the blind or blinker to bc thrown in front of the rear light; when the car is moving ibrward, the blind or blinker is always in'the rear oi this light, and will be shown to the engineer pulling the train only,

To enable others skilled in thc art to make and use our invention, we will now proceed to describe its cnnstructicn and operation.

A is the rear axle, which has cut upon it, at or near its center, a screw-thread, A.

B is'a spindle, passing vertically through the body'ifi of the car. To the lower end of this spindleis attaehed a cog-wheel, B', which meshes in and gears with the'screw-thread A. 'lo the upper cud of this spindle B is attached a crank-wheel, C. On this crankwheel, and near its periphery, is a pin, c, on which are pivoted two crank-arms, O O. The other ends oi these crank-arms are secured to the handles C2 2 oi' the blinds or blinkers O3 O3, These handles C2 G2 are supported by and workin slotted ghide-plates-el et, sccured to the top of' the car; or, if preferred, these hair. dles G2 C2 may be dispensed with, and the crank-arms C* C I nay be secured dircctl'y'to the blinds or blinkcrs G3 O3. y

The blinds or blinkers G3 CR are so formed that they pass both in front and in rear ot' the stationary lights c'L c on the sides of the car. These lightsc" c arc sccured in proper cases, so that the light emitted-from them shall be steady and uniform. To the circumference ofthe crank-wheel G are pivoted, on opposite sides, two pawls, IZ rl.

F is a standard secured on the rear end 'of the ear.l

On the top of this standard is secured a third light, et

ff are two blinds or blinkers, one in front and the These blinds or bliukers are pivoted to two plates, h h, said plates being pivoted on a pin, h', which passes through the top of the standard F, as clearly shown in iig. 3.

`glhrough the top of the lower section ot the standard F passesa pin, H. fastened a short lever, It, which is connected by a wire, k', with one of thc plates h. To the other cud of this pin Hl is fastened a slotted lever, F.

L is a double crank-lever, which h as its l'ulcrum in a suitable plate fastened on the-tcp of the car; and between the standard F and the circular plate D, through which passes the spindle B. This circular plate 1) has aslot, d', cut in it, said slot being oppesite the fulcrum'of the double crank-lever L. Oncarn-I,

l', of the double crank-lever works'in the slot of the lever F', while the other arm, I, extends suiliciently far over the circular plate D to be operated upon by the pawls IZ d.

To the rear end of this. pin is or blinkerscoverim1 the side-li'hts still` move alter-` nately vback and forth, but as soon as the pawl d roaches the arm Z it `passes; under and lifts the same.` This movement, through the arm l', causes the slot ted lever F to change its' position, and, by means of' the lever-7a, causes the blind or blinker to be thrown in front of the rear light, thus giiiingwarning to the engineer' of the following train, that the train ahead, or a portion of' the same, has stopped.-

'Having thus fully described our invention,

\ What `Weelaini therein ns new, and desire to secure byLettcrs Patent of `the United States, is

1. The cog-wheel B', spindle B, crank-wheel (l, crank-arms Cl Cl, and blinds or blinkers' C G3, with or without their handles C C2, when the whole is so arranged as to operate substantially as described.

2. 'lhe cog-wheel B', spindle B, crank-wheel C, pawls d d, double clank-lever L, slotted lever F', lever is, and blinds or blinkelsff, when the whole is so ar-` ranged as to opera-te substantially as described.

In testimony whereof We have signed our names to this specification in the presence of two subscribing witnesses.
