To all whom it may concern:

Be it known that 1, CHARLES ANDERSON, a citizen of she United States, residing at Omaha, in the county of Douglas and State of Nehraska,'ha.vc inyentecl certain new and useful Improvements in Railway-Switches or the like, of which the, followingis e de-- scription. Y My invention belongs to that class of (levices known es railway switches or the like, and refers particularly to that class of switches edepte'cl to be operated or controlled from a par'riculer or ceniral controlling" or opcreiing point, which may be proximate to or at some distance from the switch "so be operated The preferred construction shown is e self-adjusting electrically operated switch for use wherever applicable.

invention has among its objects the production of a simple, eiiicienis, safe 21ml satisfactory switch of the kind described for use wherever it be found applicable, and a. swiich that roe-y be constructed and installed at acomperetively low cost.

The preferred construction shown may be very readily. and, satisfactorily installed to replace many of the devices now in use, there being a subsceniicl recluction the number of parts and size over devices commonly in use thereby being less apt to get out 01" order as well es'beingzj more convenient for installation. in some cases it may he installed to replace other forms, using the same or former controlling system, or the preferred or equivalent controlling system may also replace the old.

' To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described and more particularly pointed out in the claims.

Referring to the drawings the usual form of railroaclswitch is shown comprising; the stock rails 1,3, 1 and. 3 she move I. switch points or parts 2 and. i, with my in venlion applied thereto. is may he assumes for convenience in describing the device the; I

when. the switch parts or points 9. and 4i are n the pos1t1ons'shown, the swlfbch ports are in normal position so that a tram will travel upon the stock rails 1 and 3 on to the shock;

mil 1} and switch part 2, etc. If the switch is opened (or the parts in reverse posilicns} then the trainwill pass from the mils l. ans 3 on to the switch port 4 and stock rail 3 etc. Suitable ties 7-7, etc, of the usual or any preferred construction or material may be provided and the railsenclswitch poinis supported thereon in any suitable way,

plates or the equivalent being prefer ably arranged as shown. The swiich points 2 and i are adapted to he moved from ihe position shown to the right so time the point l rests againscthe rail 1 and flshe point 2- away from thexrail 3. The points or parts 2 and. 4 may be provided with any suitable meensl'for causing them to move together, as shown they are preferably secured icgether by means of suitable connecting or spreader bars 9 and 10, the seine being arranged so as to permit the movement of the parts as above described. The ports are securely .retainedin the desired relation to each other since the spreader bars are continuous and secured directly $0 the parts by means of suitable brackets 21 and. bolts 22 and 23 pron-equivalent arrangement. It shoulcl'b c-notedthnt while two switch points or parts, 2on6. 4 respectively, are shown there may be but; one movable part, as for example, the switch commonly used for sircet railways or for (lerails, etc. 7 It should also be mentionecl'that She rails end switch parts or points, ties, etc, may he of such design or construction as preferrecl.

Secured to the bar 9, as shown on the extension 11, is a suitable throw rod or bar 12 operatively connected with suitable mechanism for moving the same. In the.

preferred construction the throw rod 12 is operatively connected with an electric motor and the operation of the device brought about by driving the motor in one direction or the other to move the parts to normal or reverse position as desired, The spreader bar 9 is also connected by means of a suitable rod 16 or the equivalent to an arm 49 as more fully described hereafterJ A rod 17 is preferably secured to the stock rail 1 as shown. and to a movable contact member 1 arranged within the casing 13, the purpose and operation of. the same being more fully eX lained hereafter.

In the PIQGITGd construction, resilient members 15-15 or the equivalent are provided as shown between the spreader bar 9 and the rod 12 so that the two are substantially yieldingly or resiliently secured to gether.. The springs areof such strength that they willnot be compressed to any appreciable extent in throwingthe switch.

points from one position to the other. They not only act as acushion when .thepomts are thrown from one position'to the other,

but should a train run through the switch while closed, that is for example,- when the switch points are in the position shown should a train from the stock rail '3? and the point 4 run through the switch onto the stock rails l and 3, the switch points will give way owing to. the resilient connection mentioned and the train pass safely through without in' any way injuring the switch or the operating mechanism. Y

The rod 12 is connected or "setured to a rod 24, extending within the casing, by means of pin 25 or the equivalent, so that the same are pivotally secured together and:

form the throw'rod. The'rod.24 a;; ifs suitably supported within the casing l3and provided with a thread and a gear 26 positioned on the rod. The gear 26 is free to rotate on the rod 241m is retained from moving longitudinally by the extension27 of the casing and a shoulder-28, so that rotating or driving the gear in one direction or the other longitudinally moves the rod in one direc? tion or theother, thereby shifting or moving parts 2 and 4 of the switch. As shown ball bearings 29 or the equivalent may be arranged to decrease friction and prevent the gear 26 from binding. Any suitable means may be employed. to operate'gear 26, the pre '-ferred construction comprising'a gear or pinion 35 arranged to be driven by shaft34: which is in turn driven by thelmotor. As before. mentioned the preferred construction is a motor arranged to drive the shaft 34 in either directiomsuitable means being employed trrcontrol the motor as desired. The

gear or pinion 35 is preferably .yieldingly secured on the shaft 34, as shownby means of the cone 36 cooperating therewith, and, a resilient member 37 retained by the nut 38, the resilient member tending to normally force the cone into driving contact with the This construction takes all shock I off 'of v the motor when the points'have pinion.

with the bevel gear face 32 arranged to conoted that this construction comprising the rod and gear rotatable on the same as described, prevents rebounding of the switch points inasmuch asthe arrangement of the gear and threaded rod substantially forms the lock in itself. This arrangement and the resilient members 15 together form a very satisfactory resilient or yielding lock for the switch points. Auxiliary locking means may be employed however, if desired, as is more fully explained hereafter. The movement of the rod 24 may be limited by means of a pin 39 or the equivalent as more fully explained in the operation of thedevice. The casing 13, and removable top 13 for the same, protects it fromthe weather, keeping out both moisture and dirt. If desired, a suitable amount of oil, preferably non-freezing oil, or the equivalent may be placed in the casing submerging the parts. As shown suitable packing 40 may be provided if desired' to prevent the leakage of the oil from within the casing.

As before mentioned the gear 26 is preferably driven by means of an electric motor or the equivalent for the purpose, the direction'of ratati i of the gear being controlled by controlling the motor, preferably by changing its polarity. larly to Figs. 4, 6 and 7 in which the same is most clearly shown the arm 4:9 (to which is secured rod 16) shaft 50 which extends to the interior of the casing and provided with an arm Arm 52 is provided with a pin or extension 57 arranged to cooperate with suitable extensions or lugs 58 and 5.9 of a circuit breaker or switch comprising the bars 55 and 56, which are suitably insulated from each other, and contact points and guides 53- 54, (SQ; and 61. The contact 60 may be subsl\a11- ti'ally rigidly secured to the casing 13, be ng insulated therefrom, so that the same is practically muintainedin position relative to the stock rail 3.

main or operating circuit controlling the motor when the contact is broken at the As is obvious when the contact is broken the motor stops. Contact 61 beingcontrolled by the rod 17 which is in turn secured to the stock rail 1,

indicates 'the condition of the stock rails,

the switch'being self-adjusting inasmuch as the movable ,switch points must reach the stock rail beforecontact is made with the contact point 61. If the switch points are not-in the safe position there will be no contact. at the point mentioned. llhe few turns which the motor makes after the power is turned off or the operating circuit broken, generates a small current which 'is used to give an indicati'on at the tower, the indicatingcircuit shown being as follows: assuming it to start fromthearmature A, We have 106, 105, 104, 67, 65 93, 91, 95, F

In case the stock rail has spread beyond" .the danger point, the pin 39 in the rod 21 will prevent the movable switch parts from traveling up to. the stock rail or beyond a point that is unsafe. In this case the pin 39 will contact with the casing and limit the movement of the rod, pinion 35 slipping on the shaft34. Theswitchpoints not moving up to the s'todk' ntail the bar- 56 will not con- Y tact with the 611 555. point 61 and consequently therewill be ,no indication at the tower that the switchpoints are against the stock rails or moved to the lint-it offltheir. travel thereby showing or indicating that theswitch is in an unsafe condition- -To throw the switch points'back to the '0; coil 4 1,109, switch 72, 108,

normal position as shown in the drawings it being understood that the parts are in the positions' as last mentioned the switch S is thrown as indicated in the dotted lines in Fig. 12 so that the several circuits are as follows: the normal controlling circuit and 88,89, 90, 115, 86,116,66, 65 ,102,101, 100, F 99, F 98, 97, F 96, F 95, 94,, 93, 65

67, 125', 104;, 105, 106, armature A, 107, 108, switch 72, 109, coil 44, 110, 111, 85, and-88, thusoperating the-motor but driving the pinion in a. reverse direction so that the switch points are thrown back as shown in the figures. VVhen theiswitch points reach their limit of'travel the circuit is again automatically broken, the bar 55 contacting with the contact point 60 so a circuit is formed as follows: 88, 89, 90, 115, 86, 117, 53, 55, 60, 118, 63, 119, 111, 85, and 88 and the coi163 is energized drawing the movable switch part 65 away from the contact point 66 and 67 thereby breaking the circuitand stopping the motor. The indicating circuit may be traced as follows: armature A, 106, 105, 10 1,

103, 68, 65 102, 101, 100, F 99, F 98, 97, F 96, F 95, 94,93, 65 69, 92, 87,124,120, 121, 122, 123, 85, 111, 110, coil 41, 109, switch 72, 108, 107, and armature A, thereby giving a signal at the tower and indicating the 0011- dition of .the switch.

It is of course. understood that a train entering upon the detector bar would breakthe circuit at 72 so that the switch could not be thrown in either direction thus preventing the switch from being thrown while a train is passin It should be noted that while an electric motor is shown arranged to drive or operate y the throw rod, the same might be replacedby equivalent means arranged to operate the gear 26 or the equivalent. In the case of the substitution of equivalent driving meanslfor the motor it is obvious that the controlling circuits or the equivalent controlled byf-the movable and fixed switch parts may be arranged to control; the driving mechanism.

The same is likewise true of the main operating circuits of the device.

To mention a few of "the advantages of the applicants device'it should be noted that the device is substantially controlled by the movable parts. and stock rails; that the spreading of the stock rails beyond the danger point isindicated; that it is impossible to get a proper indication at the tower unless the switch points are in proper position; that the switch points cannot rebound; that the'throw rod initself forms substantially a locking rod; that the adjustment of the switch is not affected by the running of the steel in warm weather or the creeping of the switch points due to traffic; that the detector bar is. not raisedby the switch mechanism but is normally held in operative position, breaking the circuit when depressed by a movable switch part, a throw rod therefor, a shaft operatively connected to and arranged to cotiperate with said rod, and means for driving said shaft, said driving means comprising a motor, an operating circuit therefor, an auxiliary controlling circuit for said operating circuit and a controlling switch for said auxiliary circuit provided with normally immovable ele ments connectedwith said stock rails and movable elements connected with said movable switch part.
