UNITED y,STATES PATEMOFFICE GABRIEL r. BORN AND RUSSELL n. BORN,Y or NEW PHIL-1113131.33111, onro; 1 j' AUTOMATIC RAILWAY` SIGNAL.'

Application led February To all whom 'it may concern:

Be it known `that we, GABRIEL F. BORN and RUSSELL D. BORN, citizens of lthe United States, residing at New Philadelphia, in the county of Tuscarawas, State of Ohio, have invented certain new and useful Improvements in Automatic Railway Signals; and `we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

' 'This invention relates to new and useful improvements in railway devices, and particularly to signaling devices therefor.

' One object of the invention is to provide a novel construction of signal, and train operated means for actuating the signal.

' Another object is to provide a device which is especially adapted for use at railway crossings, and which produces an audible as well as a visual signal, at the approach of a train to the crossing.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanymg drawing.

In the drawing:

Figure 1 is a top plan view of the invention in use.

Figure 2 is a side elevation of the device, showing the relation and connection of the parts.

Figure 3 is a vertical sectional view on the line 3-3 of Figure 2.

Figure 4 is a side elevation of the track tri llieferring particularly to the accompanying drawing, 10 represents a portion of a railway, and 11 the railway crossing. Mounted on one of the ties 12, of the railway, and at a suitable distance away from the crossing 11, is a bearing bracket 13. Movably supported on this bracket is a rock shaft 14, having a curved arm 15 on one end thereof, said arm being normally held at the approximate level of the tread of the adjacent rail, to be engaged and depressed by the langes of the wheels of a passing train. Mounted on the outer ends of the ties, adjacent the bracket 13, and extending to a point adjacent the crossing 11, is a pipe, or other hollow conduit 16, through which extends a cord, wire, or chain 17. On the other end of the rock shaft V14A there is mounted a radial arm 18, `.and connected to the outer end of this arm is the 4pressing same.

end of the said element 17. f

Mounted adjacent the railway crossingis avertical frame 19,'which includes the cross bars 20, 21, and 22, and the uprights 23.

adjacent Mounted onone of these uprights are the.V

grooved wheels or pulleys 24. Pivotally supported in an upright'position', on the intermediate cross bar 21, isa pendulum 25, the lower end of which has the spaced disks 26, each of which is -providedwith an opening' 27 in which is lsecured a piece'of colored glass 28.` On the lower cross bar 22 there Vis mounted a lantern'29, which is hidden when the disks are in normal position, but which is arranged to be seen through the glass 28, when the pendulum is rocked lto dispose the openings 27` opposite said lantern. Secured to. and depending 'from the upper bar 20 is a bell 30, and within this bell is disposed the knobbed upper end 31, of the pendulum 25, and which knobbed end is adapted to strike the bell, upon the pendulum being rocked. Mounted on the upper bar 2O is an electric lamp A32, a wire extending therefrom to a stationary contact member 33, mounted on the bar 21, adjacent the pendulum, as shown at 34, while a wire 35 extends from the lamp to a source of electric current, not shown. Secured on the pendulum 25, in position to engage with the contact member 33, upon rockingof said pendulum, is al contact member 36, from source o-f current.l A coil spring 38 is con- A nected, at one end, to the pendulum, below the pivot thereof, andl at its other end to one of the uprights 23, for the purpose of maintaining the "pendulum in normal upright position, and the openings 27 out of line with the lantern.-

On one of the ties, adjacent the crossing, and the adjacent end of the conduit 16, is a grooved wheel or pulley 39. The end portion of the iiexible element 17, remote from the trip arm 15, is passed around the pulley 39, and the pulleys 24, and is secured to the pendulum, above the pivot thereof.

It will thus be seen that, upon the approach of a train, to the crossing 11, the wheels of the locomotive, and the succeeding cars, will pass'over the trip arm, de-

This movement of the arm 15 causes the rocking of the shaft 14, which exerts pull on the flexible element 17, with which extends a wire 37, leading to the .90

the result that `thependulum.is swung. on its pivottov strikethe bell, expose thexlantern through the openings 27, and close the circuit through the contacts 38 and 36, to light' 'the lamp 32." Thuspersons approach'- ing the railway, train is approaching the crossing, Will be quickly apprised Vof the factv by the ringing of the bell, and the showing of the lantern, aswell as the electric'lig-ht. In the event that no electric our-rent: is available, the-lantern, only, isvused, thus providing for audible, as Well asvisualsignals to give Warningrof the approach of a train.l

It Willzalso be noted: that the'coily spring 38 vrestores the tr-ipfarm l5 vto normalposition, as Well. as: the pendulum.

A railway signaling device including a bell having. a striker, a normally lighted lam-p, means on the strikerl normally `concealing thelamp, means carried bythe conceallingI means -or exposing thelamp, and means'operable by a train for actuating the striker into contact with the bell whereby said concealing means will be moved to eX- po'sethe lamp.
