RAILWAY SIGNALING APPARATUS.
SPECIFICATION forming part of Letters Patent No. 775,797, dated November 22, 1904.
Application filed October 6, 1902.
To all whom it may concern:
Be it known that I, JOHN T. CADE, a subject of His Majesty the King of Great Britain, and a resident of Midland township, in the countyv of Bergen and State of New Jersey, have invented certain new and useful Improvements in Railway Signaling Apparatus, of which the following is a specification.
My invention relates to railway signaling apparatus, and the means embodying my invention, hereinafter particularly described, are adapted for use in an electrical automatic signaling system. u
According to my invention I produce two different clear indications with the employment of a single clutch.
According to my invention an actuating part is provided which receives motion from a suitable motive mechanism under the control of such single clutch and which produces one clear indication in one part of its movement and the other clear indication in another part of its movement.
My invention also includes a lock for holding the home signal at clear, such lock being controlled by the actuating part, and my invention includes various improvements in the construction and combination of parts, and has for its principal objects simplicity of construction and reliability of action and durability.
I will now describe the railway signaling apparatus embodying my invention, which is illustrated in the accompanying drawings, and will thereafter point out my invention in claims.
Figure l is a side elevation of a signal embodying my invention with the signal-box in section. Fig. 2 is an end elevation of the signal-actuating mechanism. Fig. 3 is a de tail side elevation of the signal-operating levers and engaging part and back plate, showing the normal position of these parts with both signals at safety. Fig. 4 is a detail section on the line 4: 4, Fig. 2, of the sliding contact for the conductor of the clutch-electromagnet. Fig. 5 is a detail side elevation, and

Figs. 7 and 8 are similar views with the home signal at clear and the distant signal at danger. Figs. 9 and 10 are details of the movable lock and adjacent parts. Fig. 11 is a vertical section of the upper part of the post, showing the connections between the up-and-down rods and the semaphores or signals. Figs. 12, 13, and
14 are enlarged sections on the line 12 12, Fig. 2, of the circuit-controller for the motor 0 and clutch circuits in different positions. Fig.
15 is a diagram of the controlling-circuits of the motor and the clutch.
I shall describe the operation of the signal apparatus in a normally clear system, and Figs. lto 4:, inclusive, and Figs. 12 and 15 illustrate the position of parts with bothsignals in the clear position. The drawings illustrate a construction of signaling apparatus in which two signals are employed a home signal 16 and a distant signal 17such signals constituting signal indicating means constructed to give three diiferent indications of the conditions of railway traflic, two blocks clear with both signals in the safety position, as shown in Fig. 1, one block clear with the distant signal only in the danger position and danger or train in home block with both signals in the danger position.
The signals are shown as carried upon a signal-post 26. The signal-box 27 is secured upon this post and incloses and protects the signal-actuating mechanism. The up-anddown rods 1% for the home signal and 15 for the distant signal extend up through the post. 5
The actuating means for the signal mechanism are shown as consisting of an electric motor M, supported on the base 10, preferably pivotally on a vertical axis, so that the motor may be turned to permit ready access 9 for cleaning the commutator-brushes,&c. The shaft m of this motor is connected by a clutch 11 with the shaft of a pinion 1, carried in bearings in the standard 9, this clutch permitting the motor to be turned on a vertical axis, as above described.
The motor imparts movement to a toothed actuating-drum (L, which is loosely fitted on the main shaft (Z, so as to rotate freely thereon when not connected thereto by the clutch or electric slot mechanism hereinafter described. The connection between the motor l M and the actuating-drum (Z is effected vby a 1 train of reducing-gearing, shown as comprisl ing the pinion 1, above mentioned, meshing with the gear-wheel 2 on an intermediate shaft n, the pinion 3 on the shaft or meshing with the gear-wheel f on a second intermediate shaft 0 and the pinion 5 on the intermediate shaft 0 meshing with the gear-teeth 6 on the actuating-drum (Z. A suitable standard 7 provides front bearings for the shafts a and 0, and the rear bearing for the shaft n is provided in a standard 18, and the rear bearing for the shaft 0 is provided in the central standard 8. This standard 8 also contains the front bearing for the main shaft (Z, the other main bearing for the main shaft (Z being provided in the rear standard 19.
The function of the electric motor and connecting-gearing is to actuate the main shaft (Z when the clutch or slot is engaged to put the signals to clear. It is obvious that other constructions of motive mechanism may be employed for this purpose and that the motor may be pneumatic or gas-operated or of other suitable types.
' The clutch or slot mechanism shown is of the same general construction as that shown in the patent to T. B. Keeler, No. $2,769, dated July 16, 1885. The electromagnet C of this slot mechanism is of the well-known ironclad type, with a disk-shaped armature 20, and the armature-lever 21 has a loose and pivotal connection with the armature 20, so that the armature may freely seat itself on the poles of the electromagnet. The electromag net 0 is carried on the disk which is rigidly secured upon the main shaft (Z and is located within the actuating-drum (Z, the drum a being, as aforesaid, loose upon the main shaft (Z. The armature-lever 21 is pivoted in a bracket l 22, secured to the disk g, and its movement is limited by a back stop 23, and it has a projectingarm 24, arranged to engage with and lock the pawl 25 when the armature 20 ,is held against the poles of the clutch-electromagnet C. The pawl 25 is pivoted in a bracket 26, and its movement is limited by stops 2' and j, and when locked by the armature-lever it engages with one of the lugs .9, thereby rotatively connecting the drum 0 and main shaft (Z, so that the actuation of the drum by the motor will actuate the main shaft. As shown in Fig. 1, with the signals in the normal clear position the clutch-electromagnet C is energized and the pawl 25 is in engagement with a lugs and holds the signals at clear against 1 the resistance of their counterweights. \Vith l the parts in this position after the completion of the movement to clearthe motor is i these two signal-levers being i l, l i l deenergized, and in some instances the friction of the gearing may be relied upon to prevent backward movement of the motor and accompanying movement of the signals to danger', but I provide a weighted pawl e, which will engage with a tooth r on the drum (Z, to prevent the counter-weights from forcing the gearing and motor backward and putting the signals to danger when the clutch is energized and the motor deenergized.
The main shaft (Z carries an actuating part which causes one of the clear indications of the indicating means, as the putting of the home signal to clear by one portion of the pivotal or partly-rotative movement thereof, and the other clear indication of the indicating means, as the putting of the distant signal to clear by another portion of the pivotal or partly-rotative movement thereof, this actuating part being shown in the form of a plate f, rigidly secured upon the main shaft (Z and located thereon between the homesignal lever t and the distant-signal lever a, loosely mounted upon the main shaft so as to oscillate freely thereon and being actuated to raise the respective up-and-down rods to put the signals to clear by engagement with the actuatingplate f.
The home-signal lever t is connected with the home signal 16 by the up-and-down rod 14, which is pivotally joined at its lower end to the home-signal lever t and at its upper end to the arm 12 on the shaft of the home semaphore or signal. The distant-signal lever a is connected with the distant signal 17 by the up-and-down rod 15, which is pivotally joined at its lower end to the distant-signal lever a and has a slotted connection at its upper end with the arm 13 on the shaft of the distant semaphore or signal 17 The function of this slotted connection is to permit the distant-signal up-and-down rod 15 to perform its operations in the event of the distant signal being held at clear by freezing of the bearings or otherwise, so that the distant signal will not interfere with the movement of the home signal to danger, and this slotted connection permits the distant signal to go to danger independently by its counterweight whenever the distant-signal up-anddown rod is lowered. It is of course understood that each semaphore is counterweighted to go to danger by its spectacle, as usual, and that the weight of the up-anddown rods also'tends to move the signals to danger and the weight of the distant-signal up-anddown rod 15 will constitute the counterweighting means to open the clutch and move the distant-signal lever 25 to extreme lower position.
The normal position of the actuating-plate fis that shown in Figs. 2 and 3, with both signals at clear. The signals will have been forced to this position against the action of their counterweights by the actuating-plate f, which will have been actuated to effect such operation by the motor. I will now describe the operations whereby the signals are forced from their danger positions, to which their counterweights at all times tend to move them, to their normal clear positions. The positions of parts with both signals at danger is shown in Figs. 5 and 6, both up- anddown rods 14 and 15 being in their lowest positions. The first portion of the movement of the actuating part will clear the home sig nal, and this will be effected by the engagement of the actuating-plate f with a movable lock 1 in the home-signal-operating lever t. This movable lock 3/ is shown as having end antifriction-rollers and is fitted to slide, in a cross-slot which is formed in the end of the home-signal lever 25 opposite to that at which the up-and-down rod 14 is connected thereto, and the actuating-plate has an inclined face e, which bears against the front roller of the movable lock 9 and the rear roller of the movable lock 1 bears against the lock-plate w, which is secured to the'rear standard 19. The engagement of the movable lock 3/ and the actuatingplate f causes thehome-signal-operating lever 25 to move with the actuating-plate and force the home signal to clear. At the completion of this movement the lock 9 is in the position shown in Fig. 10, ready to be forced back into a notch 20' in the lock-plate w and clear of the actuatingplate f upon a further forward movement of the actuating-plate. Should the conditions of trafiic require only the home signal tobe put to clear, the parts will remain in this position, (shownin Figs. 7, 8, 9, and 10,) the lock y bearing against the inclined face e of the actuating-plate ready to force the clutch open should the clutch-electromagnet C be deenergized and to return the home signal to danger in such event. The movement from the position indicating one block clear to the position indicating two blocks clear or the putting of the distant signal to clear is effected by a further forward movement of the actuating-platef. The initial movement will move the lock y rearwardly into the notch w and clear of the actuating-platef, so that the further forward movement of the actuating plate will not affect the home signal. The pro jection c on the front face of the actuatingplate f will now engage with a projection 24 on the distant-signal-operating lever wand the actuatingplate will move the distant-signal-opcrating lever, thereby moving upward the distant up-and-doWn rod 15 and forcing the distant signal to clear. At the completion of this movement the parts will be in the normal position. (Shown in Figs. 1, 2, and 3 and also in Fig. 11, the latter view showing the position of the up-and-down rods let and 15.) The counterweighting means, consisting of the up-and-down rod 15, now exert a pressure against the actuating-plate f at the engaging projections u and '0 ready to force open the clutch as soon as the clutch-electromagnet C is deenergized.
Themotor and clutch circuits are controlled by the movement of the signal-operating mechanismthrough a circuit-controller at the rear end of the main shaft (Z. This circuitcontroller comprises four contact-springs M C M" C", (shown in diagram in Fig. 15,)
, these contact-springs being adapted to make contact with fixed points 30, 31, 32, and 33, respectively, under the control of rollers m 0 m 0, respectively, carried on arms projecting from the main shaft (Z, the contact of each controlling-roller with its spring closing the spring upon its contact-point. The drawings also show a construction of sliding contacts for the conductors of the clutch-electromagnet C, comprising the two sliding contacts 79, carried on arms on the main shaft (Z and moving at all times in contact with the 0011- ductor-springs q. (See Fig. 1.) The two conductor-springs q and the four contactsprings M C M ()and the respective contact-points are carried on an insulating-plate Z1, supported on a bracket 28, this bracket 28 extending rearwardl y from the rear standard 19, and the extreme rear end of the main shaft (Z is shown as guided in a bearing-piece 29, extending up from the rear end of the plate l2.
For the purpose of controlling the indieations of the signals suitable controllingmeans, automatic or manual, may be provided. For automatic control suitable circuits would be provided, affected by the conditions of traflic on the railway-line. The particular construction of controlling means or circuits forms no part of the present invention, and I have only illustrated in Fig. 15 a relay H, which will be the home relay or trz' ck-relay and will release its armature with a train in the home block, and a distant relay D, which will be included in either a track or a line circuit and will release its armature when the advance home signal is at danger or the block in advance of the home block is occupied by a train and which is shown as controlled by the home relay H through the armature-iinger 4:2,so that its circuit will be opened when the home relay releases its armature. l. have illustrated a portion onlyof the circuitof the distant relay, including the wire 43, armaturefinger 42, and wires 44 and a5, and have not shown any part of the circuitof the home relay. l have shown diagrammatieally armature- fingers 34, 35, and 42, carried by the home-relay armature and armature-lingers 36 and 37 carried by the distant-relay armature.
Figs. 12 and 15 illustrate the position of the parts with both signals in the normal clear position, the clutch-circuit being closed from the battery B through wire 38, clutch 0, wire 39, spring C", contact-point 33, wire 40, armature-linger 36, and wire 41 back to the battery. When a train passes the signals, the
home-relay will release its armature, and this will open the circuit of the distant relay D at the armature-finger 42, and the distant relay D will release its armature and open the clutch-circuit at the armature-finger 36. The armatures of both the home relay H and the distant relay D are now released. The counterweighting means will now open the clutch and return the signals to danger, and thereby the main shaft will be partly rotated backwardly; but as the clutch and motor circuits are all opened at the relays H and D no circuits will be closed during this backward movement of the main shaft, and both signals will go to danger. Then the train leaves the home block, the home relay H will attract its armature. The circuit-controller will then be in the position shown in Fig. 13, the home motor-spring M and the home clutch-spring C being closed against their contact- points 30 and 31, respectively, and the attraction of the armature of the home relay H will close the motor-circuit and clutch-circuit, and the signal-actuating mechanism will be operated, as heretofore described, to put the home signal to clear. The clutch-circuit will be from battery B through wire 38, clutch-electromagnet C, wires 39 47, home clutch-spring C, point 31, wire 48, armature-finger 34, and wire 41 back to battery. The motor-circuit will be from battery B by wires 38 46, motor M, wire 49, home motor-spring M, point 30, wire 50, armature-finger 35, and wire 41 back to battery. At the conclusion of the movement of putting the home signal to clear, the circuitcontroller willbe in the position shown in Fig. 14, with the home motor-spring M open, and thereby the motor will have been deenergized, and with the distant motor-spring M closed ready to energize the motor when the distant relay D is caused to attract its armature. The home clutch-spring C is still closed, maintaining the direct control of the home relay H on the clutch-circuit. When the train leaves the advance block, or the advance home signal is cleared, the distant relay D will attract its armature, thereby closing the motor-circuit through the distant motor-spring M and causing the signal-actuating mechanism to be operated as described to put the distant signal to clear. This motor-circuit will be as follows: from battery B by wires 38, 46, motor M, wire 49, distant motor-spring M", point 32, wire 51, armature-linger 37, and wire 41, back to battery. The distant clutch-spring C closes before the home clutch-spring G opens, so as to maintain the clutch-circuit closed without interruption. The circuit closed by the distant clutch-spring C is the normally closed circuit heretofore described. At the conclusion of this movement the parts are in normal position, the final movement opening the distant motor-spring M" and leaving the distant clutch-spring C closed to hold the signals in the normal clear position so long as the home block and the advance block are clear of trains.
If the signaling apparatus is operated upon the normal danger plan, the sequence of operations will be different from that above described, as is well understood.
It will be seen from Fig. 15 that the home relay H and the distant relay D are electric translating devices and that each controls the clutch and motor through the circuit-controller.
It is obvious that various modifications may be made in the construction shown in the drawings and above particularly described within the spirit and scope of my invention.
