RAILWAY sminerariel APPARATUS.

Application led February v20, 1905, Serial No.

To all whom it may concern: l

Be it known that I, WILLIAM MAooMBnn, a citizen of the United States, residing at Buffaldin the county of Erie and State 'of New York, have-invented a new and useful lailway SignalingApparatus, of which the following is a specification.

invention relates to railway signaling apparatus, and more particularly to signalm in'g apparatus oi the type actuated 'and governed by electricenergy. The object of my invention is to positively move, lock, 'give indication, unlock, return to noriiial,and give indication, by the applicag tionv of electric energy from-a single battery. This invention is, furthermore, an improvement upon and eral, basic invention disclosed in my applica- .tioii Serial No. 198,220, filed March 15, 1904, and it is also directly related to the invention disclosed in my application filed February 20, 19.05, Serial No. 246,534.

A further object of my invention is to employ the general means of my said former invention, and to render positive every movement or action of the signal, as above stated., and -to overcome the defects heretofore eX- isting wherein a signal has reverse position frictionally, in which there. 33 has been no indication when the signal has gono to reverse, and in which the return ci the signal 'to normal has been wholly dependent upon gravity.

Referring tothe drawing herewith, which asis .partly in elevation and partly diagrainmatic, 1 is a four-pole solenoid for moving thesignal to reverse.

-2 is a similar solenoid for moving the signal to normal.'

3 is a signal blade, and 4 is a rod pivoted to the'signalblade shank. A short shaft 5 is slidably mounted in bearings whichare secured to the signal post, and brackets 6, 6, rigidly secured to the shaft 5 are adjustably vv"secured over the shaft 4. The lower end of at; 'the shaft 5 is yrigidly secured to the common armature of the solenoids 1 and ,2. Mounted upon the shaft ,5 is a plate 7 which is rectangular at its lower end and beveled at an acute angle at its upper end. This plate 7 is secured to the shaft 5 and reciprolivoted at 9 upon the signal 3, which is provided at its latch capable of engaging Cates with it.A post is a lever arm lower end with a under the square end of the plate 7. lntegral with the lever 8 is a lever 10, which Specification of Lattere Patent.

also swings upon the pivot 0 which pivot-ed at its upper end to a rod l5, which rod l5, at its free end, constitutes an armature for the magnet 12v and is capable of being drawn into said magnet 12 when it is energized and the rod 15'is free to move. The arm 11 pivoted at 9, and also integral with the arms 8 and 10, acts as a snap-switch, as hereafter morefully described, being permanently in electrical connection with the contact plate 43, and alternately in electrical connection with ,the contact plates 44 and 45.

The armature rod ofthe magnet 13 eX- tends through said magnet 13 and at its end adjacent to the arm 3 is provided with a slot 14, which takes over a pin in the arm 8. The slotted end 14 of the armature rod 36 of the magnet 13 has an extension 94 in the forniof an L, (the l. end extending directly backwardly so that it'does not show in the draw-l ing). A plate 95 is rigidly secured to the shaft 5 and at right angles to the plate 7. The plate 95 and thfy t.,-end 94 are so positioned that, when the armature of the inagnet 13 is in its normal, medial position, the L-end 04 will lie out of plane (to the left in the drawing) of the plate 05, and so that, when the magnet 13 is energized to draw the rod 36 to its extreme (right hand) position, the L-end will lie in the plane of the plate 95. The upper end of said plate 95 stops a short distance below the L-end 94 when the signal is normal, and extends beyond the l...- end when the signal is at reverse. The 'purpose of this arrangement is to delay indica-y tion until the signal is actually at normal, asA vwill more clearly appear hereafterin tracing a movement. The outer end of armature rod 36 of the magnet 13 connects with springs 99 which tend to hold the armature of the magnet 13 in the normal position shown in the drawing, but which permit it to take the other positions at the proper time. Secured to the rod 36, but insulated from it is a contact plate 37, which makes electrical connection when in its normal position with the contact piece 38, and which breaks such connection as soon as the magnet 13 moves the rod 36. 52 is a tongue normally held out 12 and in electrical connection with contacts 39 and 40, and when the magnet is energized breaking connection with the contacts 39 and 40 and making connection with the contacts 53 and 54.

Mounted upon the armature ofthe magnet 13, but insulated romlit is a plate 49 which makes electrical connection with the contactsf50-and 51 when the said armature is 5- normal, and which breaks such contact as soon 'as said armature is moved out'(to the ri ht) ofnormal. 46isaplatesimilarlymounteg on said armature rod, capable of'making electrical connection with the contact 47 as soon as the said armature ismoved out of normal; and -48 is a plate similarly mounted and normally in electrical connection with the plate 92', but capable of breaking 4such connection and 'of making electrical connection with the contact 90 when said armature is moved to its extreme position by the release of the L-end 94 from the plate 95 as hereafter fully described.

.17 and 18 are the brushes of the controller', 20 the brush I17 making electrical `connection with the contacts 19, 20, 21, and 22; and the brush 18 being capable of making electrical connection with the contacts 23, 24, 25, and

26. 25 27 are the indicating magnets; 16 are safety magnets; 28 is a cut-out magnet, and 29 is a tongue governed by said cut-out magnet 28 and carrying the'insulated plate. 30, which is normally in electrical connection 3o with the contacts4 31 and 32; When the magnet 28 is energized, the tongue 29 makes electricalfconnection with the contact 33. v34 isa source 'of electric energy. The signalis shown in its normal or danger A35 position, and the position of the mechanism corresponds to that position of the signal. I will now describe 'themovement of the signal to reverse'andthe reverse indication." To

`produce this movement the'V brushes 1.7 and- 40 18 are moved with the controller so that the brush 17 bridges the contacts 2 0 'and 22, and the brush '18 bridges the contacts 24' and 26.

This closesa circuit of the battery 34 includ-' ing the solenoid 1i, and the magnet 1 2, so that .currentflows from battery 34 through wires 55, l56, 5 7, contact.31,'plate,30,'contact 32,'-

The current 'passing through the magnetg1-2- energizessald magnet' and-' tends to draw the 'armature rod 115 inwardly and at the Sametime moves the armature'52 against the retractile spring -u i against the end of the magnet 12, 'breaking contact with- 39- and 40 rim-making Contact with 53"' 6 5 and' 54,' The current from' batteryf final movement ofthe controller giving mdioutsideof. all magnets on the controller so 4pending application Serial No. 198,220.' The so that` the magnet 12 should be denergized,

through safety magnets 16, has energized them and produced the release yof the con.- troller, as fully described in my'said pending application Serial No. 198,220. As soon as the rod 5 has carried vthe plate 4'7 upwardly suiiiciently for the hook end of the arm 8 to engage over the end of the plate 7, the magnetic action ofthe magnet 12 upon the bar 1() Will overcome the tension of the spring 69 and cause the hook end of the arm 8 to snap to lace underneath the plate 7. This will loc the signal in the reverse position. The tongue 52 having moved to contact, as above described, the throw of-^the arm 8 into lock Will carry the arm 11 downwardly and cause itly to make electrical connection between the late 43 and the plate 45'. Current will then Bow from the battery through the path just above described to the point of union of the Wire 66 with the plate 43 and from thence it will ilow from plate 43 through arm 11, plate 45, wire 70, contact 53, tongue 52, contact 54, wires 71, 72, 73,' contact 26, brush 18, contact 24', wire 74, indicating magnets 27, wire 75, cut-out magnets28, Wires 76, 77, back to battery. This current passing through the indicating 'ma nets 27 and cut-out magnets 28 will shunt t e battery current through ,wire'78, contact 33, tongue 30' and wire 79,

around the safety magnets 16, permittinoc the cationthat the signal `is at reverse and locked, as fully described `in my aforemen-y tioned patent. The final movement of the controller will cause the brush 17 to bridge 100 contacts 2'1' and 22 instead of 20. and. 22 and will cause the'brush-"l-St bridge the contacts 25 and 26, so 'that `currentiWill flow JfromA battery 34,'through wires 55, 80, 'contact 21, brush 17 ,contact 22 and thence through the 105 path last above described, to the signaland n ack` through the indicating wire to contact 26, brush 1 8, contact 25,and wires 81 and 77 back to battery. -Tln's carries the current 110 that the slgnal-may be held at reverse inde- -pendently of the 4movement of any other 'I unit of the system, .and independently of any.
