Application filed November 23. 191 Serial No. 203,526.

T 0 aZZ whom it may concern known that l. CYRILLUS B. SEATON, i he United States, residing at in vomit of Clark and State of re invented certain new and Improvements in. Railway-Crossing Signals, of which the following is a specification.

My invention relates to new and useful improvements in signals and more particularly to railway crossing signals The object of the invention is to provide a train operated device so arranged as to be actuated by the moving train and operate a visible signal and alarm located at the crossing.

A further object is to produce a purely mechanical construction which is adapted to be positively actuated thereby eliminating any possibility of a' disarrangement of the several cooperating parts.

Figure 1, is a plan view or" my device.

.Fig; 2, is a longitudinal section through the track on line 2--2 of Fig. 1.

F 3, is a transverse section through the track on line 3-3 of Fig. 1.

Fig. l, is an enlarged sectional view through the signaling apparatus.

Numeal 1, indicates a signal tower of suitable height and located at the railway crossing. Atthe upper end of this tower is located a stubshaft 2, rigidly secured to the tower. llloui'ited upon this stub shaft is a semaphore arm 3, provided with an actuated arm 4, extending on the opposite side of the stub shaft Q. Mounted upon the semaphore is an alarm in the form of a bell 4' having associated therewith a clapper 5. com-prising a flat flexible spring 6, secured at one end to the arm, the outer free end of which is adapted to engage the bell when the semaphore arm is raised to a. danger position by suitable mechanism hereinafter described. A chain 3 is attached to the outer end of the semaphore arm 3 having its opposite end connected to a spring 2 which, in turn, is connected to the tower 1,

thereby aiiording a resilient means to limit the upward movement of the semaphore-arm 3 when the latter is actuated. v

Arranged on the opposite side of the tower 1 is a similar stationary stub shaft 8. Ro-

.tatably mounted upon this shaft are a plurality of flag arms 9, rig dly secured to a hub 10. This hub is provided with a spurgear .11, which is adapted to engage an or p the rail tuating member 19', pivoted as at 13 to the tower 1. This member on its upper side is in the form of a gear segment ll, meshing with the spur-gear 11. The outer end of this member is weighted as at 15, to cause the apparatus to return to its inoperative position after being actuated. Arranged on the several. flag arms is a signal device in the form of a bell 16, provided. with. the usual clapper 17, secured as at 1.8, to the flag arms. will be see by the actuation of these flag arms. not only a visible but an audible signal is simultaneously given to the party approaching the crossing.

The. semaphore and flag arms are preferably actuated by the moving); train and to accomplish this the following mechanism is preferably provided.

Arranged at a suitable distance from the crossing is an. actuated mechanism compris in two inclined plates 20, pivotally mounted at their outer end to a base plate 22, which is adapted to be secured- -djacent to the inner side of one of the rails A. The inner ends of these flange plates are pivoted together and suspended therefrom is an adjustable plunger 23, the lower end of which is connected to a bell crank 24. transversely pivoted to the track as at Arranged between the flange plates and i a web which is adapted to prevent any foreign substance wedgi'ng in between the pivoted plate and the rail. proper.

Numeral indicates a bell crank lever vertically pivoted as at :28, adjacent to the track, one end of which connected by a resilient member in. the form of a spiral spring 29, to the outer free end of the trans vcrsely arranged bell crank 24:. t

Arranged near the tower is a similar bell crank lever 30, vertically pivoted as at '31, one end of which is connected by suitable connecting" rod 32, to the free end of the bell crank 27. Connected to the free end of the bell crank lever 30, are a pair of cables or connecting wires 33 and 3%, the wire 33, leading to the actuating arm of the semaphore 3, While the wire 34 leads to the actuating member 12. It will thus be seen that as the flange of the ear wheel. passes over the inclined flanged plates 20, the latter will be forced downwardly thereby actuating the plunger 23, which in turn will serve to actuate the bell crank levers 27 and 30 in such a manner as to pull on the cables 83 the locomotive would reflect upon the sig-" and 34 and cause the semaphore 3, to be raised into a danger position and the flag arms 9, to be rotated, this action automatically causing the audible signal to be actuated. Immediately upon the passing of the train over the flange plates 20, the' latter owing to the weighted ends of the. bell crank 2.4., and the actuating member 12, will be re turned to their normal inoperative position. It is obvious that the several bell cranks and other rotating mechanism may be mounted on ball bearings, thereby greatly reducing the friction in manipulation of this device.

For the sake of duplicating this danger signal I desire to arrange along the track one or more pairs of the actuated flange members20 and their cooperating parts, repeating as many times as desirablethe 1nechanism to reproduce the danger signal as manytimes as occasion may necessitate.

It will thus be seen that I have eonstructf ed a mechanism which is very simple in construction, positive in operation and one.

which may be installed without any alterations whatever to the railway system.

If desired the tower may be set at a slight angle to the tracks whereby the headlight of nals.

I claim: 1. In a railway crossing signal, the combination of a signal tower, a semaphore arm mounted thereon, a plurality of flag-arms rotatably mounted on said tower, vibratory audible means carried by said semaphore-arm and flag-arms, and wheel-dc: pressed means arranged at a distance along.

the track having flexible connections with the semaphore-arm and flag-arms whereby they are simultaneously actuated.

2. In a railway crossing signal, the combi nation of a signal-tower, a semaphore-arm mounted thereon for oscillatory movement,

a plurality of flag-arms rotatably mounted on said tower, vi'bratory audible means car ried by said semaphore-arm and flag-arms, wheel-depressed means arranged a vdlstance along the track having flexible connections with the semaphore-arm and flag-arms,

whereby they are simultaneously actuated,

thereby actuating the vibratory audible means, and resilient means for limiting the upward movement of the semaphore-arm.

In a railway crossing signal, the combination ofa signal-tower, stationary shafts extending laterally from either side thereof,

a semaphore-arm mounted on one of said shafts. vibratory means carried by said semaphore-arm, a plurality of fiagarms rotatably mounted on the other stationary shaft, vibratory means carried thereby, a gear mounted on the hub of said flag-arms, a weighted gear segment. interm'eshing with said gear, and wheel-depressed means carried at a distance along the track flexibly connected with the semaphore and flag-arm actuating means, whereby they are simul-v In testimony whereof I aiiix my signature,

in the presence of two witnesses. CYRILLUS B. SEATON.
