SPECIFICATION forming part of Letters Patent No. 628,300, dated July 4, 1899. q

Application filed January 6, 1 898.

To all whom it may concern:

Be it knownthat I, WYNFoRD BRIERLEY, a subject of the Queen of Great Britain and Ireland, residing at 'Nelson,'in the county of Lancaster, England, have inventednew and useful Improvements in and Connected with Apparatus for Signaling on Railways,of which the following is a specification.

The principal object of the present-invention is to construct an efficient railway signaling apparatus to give both an audible and a Visible signal on the engine or train as to the position of the semaphore-signal, whether it is at danger or at -safety, and also to provide specially-suitable signals on the engine or train and a special contact-bar (and-adj uncts therefor) on the permanent way.

- In carrying out one feature of my invention I prefer to avail myself of the type of. railway signaling appliances illustrated in my application for patent, Serial No. 664,099, and that form of it in which'a swinging lever is mounted on the engine or other suitable part of the train in such a'position as to come into contact with a suitable projection upon the permanent way, this projection being movable and operated by the signalman or otherwise as the line is clear or blocked. This swinging lever is connected to apparatus constructed to operate a hell or other alarm on the train, and the lever is preferablyheld in normal'central position by .two reversed springs, so that the lever will act equally whether the train is moving in one direction -or the other, andthis withoutundue shock or injury. The controlling projection on the permanent way can be operated by the work-' ing of the semaphore.

' In the accompanying'drawings, Figure 1 is a vertical section of the'lever-box on the engine or other suitable part of the train. Fig. 1 is a sectional view on the line 1 1, Fig. 1. Fig. 1 is a sectionalview on the line 2 2, Fig. 1. Figs. 2, 2, 8, 3, ands are views of the improved electrical signaling appliance on the engine. Figs. 5, 6, and 7 are views of my improved contact-bai' upon thepermanent way, and Figs. 5 and 6 are views of a modification.

Referring to'Figs. l, 1, and 1 it will be.

Serial 665,811. (No model.)

observed that I construct the operating-lever a and its adjuncts (upon the engine or other suitable part-of the train) in duplicate to effect the operation of corresponding signals upon the engine. In the bOXAJ fiX two shafts a, and a the firstcarrying the pendent lever a and the second carrying the pendent lever a., The levers a a are held in their normal central positions (as in my application Serial ver in either direction causes springs a to come into contact with the springs 6%, Fig. 1,

the wires a anda or (1 01. as the case may 'or a Fig. 1, to close the circuits through be. These wires a a and a a are connected up to the two sets of electromagnets in the signaling-box D on the engine. This box D, as shown in Figs. 2, 2 and 4, is provided with an'audible signaling gong or bell d, common to both danger and safety signals. The visible danger-signal is'a disk d on a swinging lever d Fig. 2, and is moved to a position where it will show through an opening D in the face of the box D, Figs. 2 and 3, when the lineis blocked or the semaphoresignal is at danger. The visible safety-v signal is a disk (1 Fig. 2, on a lever-d and adaptedto be moved behind an opaque spaced shutter D Fig. 2, in the front of the casing or box D, so as to show the letters Safe or their equivalent through the spaces between the opaque strips-of D when the line is clear or the semaphore-signal is at safety. In the drawings, Figs. 2 and 2 for the sake of illustration, showboth the danger-signal and the safety-signal in the visible positions.

The lever cl is so weighted that when it stands in theposition shown by dotted lines in Fig. 2 and by full lines inFig. 3 it is held 2 and into contact with a spring (Z The clapper (1 carried by the armature d, at the same time rings the bell (Z.

The circuits are as follows: The wire a is connected through the binding-post 5 and wire '7 to the armature-lever (Z which is normally in contact with the insulated back-stop (1. This latter is connected to the coils of the operating-electromagnet c", Figs. 2 and 11 to one terminal of the battery E. The

spring (Z is connected through the insulated post d and wire (Z to the other terminal of the battery E.

Both the described circuits are normally open; but when the movement of the lever a closes the circuit through a a at 01 a and through the coils of the electromagnet d the bell rings and the visible signal (1 falls from the position shown in Fig. 3 to the position shown by full lines in Fig. 2. This fall of the signal (Z' causes the lever d to make contact with the spring (Z and so closes the circuit from d, d", and (K through C1 (Z armature d back-stop d coils (Z and wires 9, 10, and 11 to the battery, producing a continuous ringing of the bell until the engineer pushes upward the button (i to lift the lever (i and its disk d up into the position shown by dotted lines in Fig. :2, to be caught by the projection on the armature-lever. The spring (1 then returns and breaks the connection. Thisspring (Z performs several functions. It serves as contact-maker for continuous alarm, a support for the indicator or signal when shown, and a replacer of the said signal. Furthermore, supposing that at any time it is desired to test the battery and the signal generally before starting on a journey, the engine-driver or an inspector can by pushing the spring (1 up to make contact with the lever (I complete the electric circuit, and if the bell rings properly the apparatus is in order. This danger-signal may be used with the single form of levera, (shown on Figs. 2, 3, and 4 of the drawings accompanying the United States application, Serial No. 664,099, above mentioned;) but I prefer to use it with the double arrangement already referred to, so that the bell d-mayserve also to give a signal (though not a continuous one) when the semaphore signal is at safety or line clear.

Referring now to the safety-signal part of the device, the circuit is from one terminal of the battery E, Fig. 2, through the wire 11, binding-post 60, and wire 12 to the coils of the operating-electromagnet d thence to the frame and armature (Z wire 13, binding-post 50, and conductor a to the contacts a Fig. 1, and wire a to the battery. One of the pole-pieces (Z of this magnet (1 is extended and cranked, as shown, so as to attract a second armature (Z as well as the armature 11', to which the clapper d is fixed. This armature (l is fixed or fitted to a dependinglever (1 held in place by two reversed springs (Z actingand disposed in a similar manner to the springs c 0, above described. The lever 61 carries the disk or, plate (1 on which the letters Safe or any equivalent devices are marked in such a manner as (when the armature (Z is not attracted) to be concealed by the opaque parts of the spaced shutter D As soon,however,as the armature is attracted the bell d is sounded and the letters or devices appear in sight until the second lever a has ceased to vibrate sufliciently to complete the necessary circuit.

The next part of my invention relates to the contact-bar for deflecting either of the levers a a as desired, according to the positions of the semaphore-signal. For this purpose I use a rocking lever, Figs. 5, 6, and 7, with two ends I) b similarly formed, but one, 1) heavier than the other, I), each end forming a contact-bar, as required. The lever b b is mounted on a shaft I)", carried by suitable brackets l), fixed in such a position that the path of one lever a is above I) and that of the other a is above b The lever I) b is movedby a lever 13 on the shaft the lever b being connected by a wire, rod, chain, or cord N, Fig. 5, to the usual weighted lever of the semaphore-signal in such a manner that when the semaphore is raised to danger the part b of the lever is raised, as shown, and when lowered to safety the part b is raised by the pulling of b in the direction of the arrow, Fig. 5.

Figs. 5 and 6 show how the lever b b may be worked from severalsemaphore-signals by using a corresponding nu mber of levers-say b b .b and forming in each lever a quadrant-shaped recess I), in which a key 00, fixed in the shaft 1), can work, and thus any one of the levers b b b -say b -ca n move the lever Z) b without interfering with or moving the other levers-say Z1 (2 The part b of the lever being heavier than I) will keep the engine-signal always at danger unless withdrawn to safety. I further provide spring stops or buffers Z2 11 for each portion of the rocking bar 11 b so that thus the working part of the latter cannot get out of place by being pulled or dropped too far. Another feature of this weighted rocking bar I) b is that it can be connected to a gate at a level crossing and warn the engineer whether the gateis open or closed.

I claim as my invention- 1. In a railway signaling apparatus, the combination of two electric signals on an engine with two spring-levers also on the engine or train, and connections between the levers and signals, with a rocking contact-bar 011 the permanent way, having two contact-arms, one adapted to deflect one of said levers when the line is clear and the other arin to deflect the other lever when the line is blocked, all substantially as described.

2. The combination of two signaling-electromagnets and their respective armatures carrying clappers with a gong or bell common to the two clappers, and visible signals controlled by said electromagnets, all within an inclosing case, substantially as described.
