B-AILWAY-CROSSNG SIGNAL.

Specification of Letters Patent.

Application filed June 14, 1913. Serial No. 773,801.

To all whom it may concern:

Be it known that we, WILLIAM P. ADLETA and OSEA M. ADLE'iA, citizens of the United States ot' America, residing at Dallas, in the county of Dallas and State of Texas,

have invented new and useful Improvements in Railway-Crossing Signals, of which the following is a specihcation. i

This invention relates to improvements in railway crossing signals and has particular application to an electrically energized signal of this class.

In carrying out the present invention, it is our purpose to provide a railway crossing signal whereby both a visual and audible signal will be given at the crossing in the event of a train approaching sucl'i'crossingthereby advising pedestrians and others at the crossing or approaching the saine of the proximity of the train.

It is also our purpose to provide a rail-l way crossing signal which will embrace the desired features ot' simplicity, etliciency and and maintained at a minimum expense and one which will be reliable and effective in operation.

With the above and other objects in view, the invention consists in the construction, combination and arrangement of parts hereinafter set forth in and falling within the scope of the claini.

In the accompanying drawing; Figure l is a plan view ot a railway crossing showing the position ci our improved signal with respect to such crossing. Fig. i2 is a vertical sectional view through the signal casing showing the inner mechanism iii end elevation. Fig. 3 is a similar view taken at right angles to Fig. 2.

.Referring now to the accompanying drawing in detail, the numeral l designates parallel lines oi' rails forming a railroad trackway over which trains or cars arc adapted to travel, while the numeral 2 designates a roadway or a second trackway intersecting the lines of rails of the first' trackway at right angles thereto.

Our improved crossing signal is indicated as an entirctyby the letter S and is located adjacent to the point ot vintersection of the lines of' rails l, l and the roadway 2 sotliat a pedestrian or the operator of a vehicle upon the roadway 2 will be advisedasto the proximity of a train on the lines of rails 1, 1. In the present, instance, this crossing signal comprises a. hollow standard 3 having one end embedded in the earth and the opposite end terminatinga suitable or convenient distance above the ground.

Suitably secured to the upper extremity tubular postor l rateamaauges,1914.

of the tubular post 3 is a casing 4 composed of some suitable material and of any desired outline. Arranged within this casing 4 and appropriately fastened to the bottom wall thereof is an electric motor 5 havingv keyed upon one extremity of the shaft -of the armature thereot a pinion 6 nieshing'witha gear wheel 7 lkeyed upon a shaft 8 journaled4 in the end walls of the casing 4 andextend ing longitudinally o'l' the lattter above the motor This shaft 8 has suitably fastened upon each end thereof a hub from which radiates a number of blades 9 adapted to rotate under the actionV of the shaft 8 and motor 5 so as to signal a person approaching the1 crossing from either side of the lines of rai s 1, 1` il Suitably fastened to the top Wall ofthe casing 4 is a bell or gong 10 disposed Within the influence of a tapper 11 pivoted upon a bracket 12 arranged within the casing 4 and depending from the top wall thereof, the tapper projecting through the top wall ot the casing and has the lower extremity of the shank or stein thereof equipped with a` dog 13 disposed within the viniuence 'of a ratchet wheel 14 keyed upon thepshaft 8 adjacent to the gear wheel 7. Thus, it Will be seen that as the armature shaft of the motor 5 rotates motion will be transmitted to the shaft 8 through the medium of the pinion 6 and gear 7 thereby rotating the signal blades 9, while at the same time, the ratchet wheel 11- will rotate and so oscillate the hammer or tapper llto sound the bell or gong 10 whereby an audible as Wellas a visual signal will be given. 7

In order that the crossing signal will be effective at night, we mount upon the,` top of the casing 4 an electric lamp 15 connectedI in multiple in an electric circuit composed ot' conductors 1G and including the motor 5,

a suitable. source of energy such, for instance, as a. battery 17, and a portion of the lines ot rails 1, 1 at both sides of the crossing. In the present instance, the battery 17 is arranged within a housing'18 carried by the post 3 so that access may be had to the battery for replenishing or ,repairing the same.

los

lt will be seen that the circuit of the niter nfl lamp is normally open und Closed by the axles and wheels of :t train entering the insulated portions of the lines of rails l, l. f'

lt will, of eenrse, be understood that the portion oit the truck included in the motor eircnit 2 is @if such length its to insure the giving nl" :l signal ut the eros ing for u e011- sidernlile length of time previous to the trein passing over the crossing.

We elimini:

A railway grossingf signal comprising z casing', n niotor-withii'l said casing, :t shaft jourimled in the end walls olI said easing :unl extending longitudinally. thereof; driving connections between said motor :mel shaft, an elec. ie lamp mounted upon. the top 0i said casing, blades radiating from the opposite ends of said shaft and movable across the path of the light rays from said lump, :l bell mounted upon Suid easing, 2r tzrpper for said bell, n ratchet wheel fixed to suizl shaft :unl adapted tovaetxmte said tapper to sound the bell, :m electric eirenit including said motor und lmnp, und imams ttor closing s-(ticl circuit whereby the motor :unl-lmnp will be energized and the shaft rotated to revolve the blades across the path 0l the light rays issuing 'from the lump and sound the hell.

ln testimony whereof We ztlix our signatures in presence of two Witnesses.
