SIGNALING DEVICE.

Patented J une 26, 1906.

To all whom it may concern:

Be it known that I, CHARLES C. PHILLIPs, a citizen of the United States of America, residing at Owensboro, in the county of Daviess and State of Kentucky, have invented new and useful Improvements in Signaling Detively simple device of t vices, of which the following is a specification.

Thisinvention relates to railway-signals designed for use on electric or steam roads and of the type embodying an automatic electrically-operated signaling mechanism, and has for its objects to roduce a comparaiiis character which may be inexpensively installed for use, one wherein a signal will be dis layed at a signaling-station or other desire oint in advance of a car or train for giving ue notice of the approach of the same toward the signal-station and one in which the signal is automaticall controlled through the medium of trac devices actuated by the car-Wheels.

With these and other objects in view the invention comprises the novel features ofconstruction and combination of parts more fully hereinafter described.

In the accompanying drawings, Figure 1 is a top plan view of a section of a track, showing the signal.` operating and resetting devices of the system. Fig. 2 is a diagram of the electric circuit. Fig. 3 is a longitudinal section through the track, showing the operating and resetting devices and the signal mechanism. Fig. 4 is a cross-section through the signal mechanism, showing the signal in normal non-danger position. Fig. 5 is a similar view showing the signal set to danger position.

Referring to the drawings, 1 designates the rails, and 2 the ties, of a track. Alongside the track at a oint in proximity to the block or other signa ing station is arranged a casing 3, sup orted by a hollow standard 4. The sides of t 's casing face in opposite directions along the track may be composed of or provided with glass or other transparent anels. shaft 5 is journaled in the sides o the casing or in the arms of a yoke-shaped shield 6 and carries at each end a signal-arm or semaphore 7, said signal-arms being rigidly mounted upon the shaft for movement therewith and a apted to drop by gravity from their normal or non-danger osition to the danger position, (indicated y dotted lines.) The v 4the latch.

shield 6 has its side o'rtions extending down on opposite sides o the casing and may be constructed and secured thereto in any prei ferred manner.

On the shaft 5 is a detent 8, having a catchhook 9 and an engaging arm `10, said hook being adapted to be engaged by the hooked end of a plvoted latch 1 1, normally held projected by a spring 12. to be retracted by a pivoted armature 18, controlled by an electromagnet 14, said armature having The electromagnet is arranged in a normally open circuit 16, containing a battery 17 and including a pair of contact-pieces 18 19, of which the latter is in the form of a track-lever, disposed adjacent one of the rails for operation by the wheels of a passing The latch is adapted car and normally held out of contact with 4 the piece 18 for 'maintaining the circuit open by means of a spring 20, while a second normally open circuit 21, containing a battery 22, includes the shaft 5an`d 'arms 7, darried thereby, and also a lamp 23, disposed in the y casing and having one of its Wires leading to a contact-piece 24, adapted to connect with a contact point or button 25 on each of the semaphore-arms to complete the lamp-circuit when the arms swing to danger posItion, this circuit being maintained 1n normally open condition through engagement of latch 1l with hook 9,

In practice as a .train approaches the sig nal-station where the box 3 is situated the lever 19, which it will be understoodis located at a point suitably remote from such station, willbe operated by one of the carwheels or in other suitable manner from the locomotive or one of the cars for movement into engagement with the contact-piece 18,'

thereby closing the circuit'l to energize the 4magnet 14, thereby attracting the armature station the semaphore-arms will be returned to normal position and the lamp-circuit circuit 16 be move again opened 'through the medium of resetting mechanism now to be described.

The signal-resetting mechanism comprises a rock-shaft 26, journaled in bearings on the track and providedwith a trip-arm 27 and an operating-arm/28, the latter being arranged to engage the lower end of a rod 29, slidably mounted in the standard 4, the upper end of the rod being disposed to engage the engaging portion or arm 10' of the shaft 5, whereby upon the upward movement of the rod the semaphores Will be returned to normal non-danger osition andlooked in such condition throng engagement of the latch 11 with keeper 9, it being obvious that the latch will as soon as the lever 19 is moved by spring 20 to normal osition for breaking the spring 12 to engagin position. The lever 27, which is operated eit er by the Wheels of one ol the cars or by a Xed arm on the caror locomotive, is after such operation returned to and maintained innormal position through the medium of springs 30.

The operation of the mechanism Will be readily understood from the foregoing description, and it will be ,seen that a simple and eective signaling apparatus for the purpose set forth is provided. When the sys-I tem is employed on double-track roads, it Will of course be understood that the si naling devices are duplicated alongside eac track. In shingle-track systems the parts will be properly arranged for the control ofv the semaphores and lamps by trains passing in both directions.

Having thus described my invention, what I claim s 1. A signaling system of the type described comprising a normally open circuit including under the influence lof saires when the circuit'is closed, 'an armature en gaged With the latch member and operable y the magnet for moving the latter to releasing position and permitting the movable contact to close the rst-named circuit, an automatically-operable track device for closing the second circuit, and ineens forreturning the movable contact member to normal position.

2. A. signaling system of the type described comprising a normally open circuit including a lamp and a contact-piece, a movable signaling-arm included in said circuit and having a contact portion adapted to connect with the contact-piece for completing the circuit to li ht the lamp, a latch member for holding sai armin normal position with the circuit open, a second circuit including a magnet adapted to be energized when the circuit is closed automatically, operable track devices for closing the second circuit, means operated by the magnet when enerized for moving the latch member to reease the signaling-arm and close the firstnamed circuit, and automatically-oi err-able track devices for resetting the mec i :ai A

and returning the signaling-arm tonormal position.

In testimony whereof I affix my signature in presence of two Witnesses. i
