To Min it mq? concern: 0 Jia is well known, the fault of many colli- Be it known tha I, Fna M. Olona, n citimonal at Vinvitching pointe on milwaya liee as at' aenot the United States, residing nt Ba City, m-the'county of Bay and lState of Mie an, 5 have invented certain new and useful mpmvemente in Automatic Switch Mechannains; and I do hereby declare the following tobe a full, clear, and exact description of the invention, auch ns will enable others t ekilled in the art to which it appertnins to make-and use the same.

My invention relatee to automatic switchee for railways.

One 'object of my invention ie to provide means for preventing collisions between n train on a siding and a train following in the eamo direction when the brakeman of the train on the aidmg fo te to throw the switch to leave 'the main trac eiear. $0 Another object ie to provide a switch with mechaniam 125 and operated by a ear device actua y the engineer.

'A further object is to plrovide means i'or looki the tiret train on t siding after tht` u me'i'i...

to clear the main track. v

A still further object is to provide means 'for automatically reeettingthe car device after the switch han been t rown. 80 A further object ls the provision of means for permitting the engineer to throw the car.

device into operative position. Another' object' is the provision of menne for disengaging the ear device from its opermeans until the cardevicc haa been reset. Still another object is to provide n switch capable of automatically yielding to permit. the of a traintraveling on the :nain track in a direction op ite to the switch. 404 Another object is t e provision of means for automatically throwin a pivotaily hupported car device to either imitl of its movement when it has dead center.

To theee and other ends m invention consiste incertain novel detai and combinatiene such as will be more lully described hereinafter and particularly pointed out in the'claims.

ln the accompanying drawings, Figure l is a pent tive view showing one ferm of. the

track* evice applied to a switch, Fig. 2 is al top plan view of the eamo, Fig. 3 ie a repective view of one form of car device, 1g. 4 is a detail view showing the switch bar cones struction and Fig. 5 ie a detail of the contact member in operative position.

been thrown by the'tollowing trainl with the brukcnian operating the switch. A freight or other train is ordered eide-tracked e0 or is switched oil the main line and the brakemnn forgets to cloee the switch to leave the main track clear. Another train following the tiret takes the witch instead of remaining on thc main track and crashes into the e5 l rear end of the tiret train or collidee head on with a train coming in the oppositedirection on the side track, because the engineer of the second train doen nor have time to apply hie brakes 'before taking the switch. 'l0

It inthe main obiect of my invention to provide means whereby auch disasters may e avoided, to whichond I have devised tho following construction ne one for accomplish i this purpose. 75

elerrm to the d'rawinga A, A, indicate the main ruck andB, B, the spur or eide track. I p

(Y, t', indicate the movable switch tongues conncctcd bv a switch bar (l), in thc usual 8,0 manner. 'l ie switch ha r i connu-lcd tothe switch stand.

In nccompliahing thc end desired, my intention ia toeqnip tho pilot of an engine with a contnct'mcmber o any suitable form 85 ndapted'to en age e. suitable track member connected to ti een-itch bar inench manner that the travel ol' the engine will cause the contact member to bcar against the track nicmbcr and' through auch track member, 90 closc thc switch to givc a clear passage over the main linc. As onc auch track meniber l may provide what lwillcall a glance rail, (2), whlc i is located neferably between the rails of the main trac The glance rail may be Us of the usual Tfrail construction, that' end ot the glance rail fart-hcet from the free ende of the switch tongues being secured to one of the vtice `(3l either-rigidly or Ipivotall ee shown nt '(4)1' 'lhe' opposite end ofythe ance vrail is seculrd to the switch har (l).

t is obvious thatthcrc must either be a thrust lmovement of the contact member relative tothe engine to move the track mcmbcrawl f thus close the switch or else the contact mem- 105 ber muy be stationary as regards lateral movement which willanakc it neeesearyto arrange the track member atan angle to the path of travel of the contant member.

In thc prem-ni construction l have' shown 110 thf` track member extending obliquely reletivc to thc path of travel lot' thc contact member. lleneewlien the contact member tion to the other. Hence it will be lseen that is thrown into operative position it will engage the track nieinher and l'oreethe latter together with the switch tongues laterallyr to close the switch. My invent-ion however contemplates further developments. It is common to connect a'rigid switch'liar to a switch stand comprising a casing (5), in which is jooriniled a semaphore shaft (o) carrying c signal (7). The shaft is roteted by means of u lever (8) locked in any suitsble manner. In the present instance' 1 have shown euch lever (8) as being iivotally connected tothe shaft and receive le in re ceases (9) in the casing to lock the switch iii o ienor closed position. lt is obvious that i e switch is provided with such har and locking means, it would be impossible to throw the switch by' the engagement. of the contact and track meinbers as shown. I therefore provide a yielding connection extendin between the .switch tongues and semiip ore shaft, such connection permitting the switch to be locked in either ol its posi-v tions end yet ellowin the switch to be thrown'lroin open to c osed position by n train on the mein track vwhenapproaching the o n switch. It also permits s train eproec 'n'g en open switch, onthe mein line, rom the opposite direction to swing the switch tongues over as it passes, t e switch ton eegetuming to open position s'fter the t t hes passed.' Ae one'such yielding connection I may provide'the switch har (i).

with e socket (10) adapted to telesco ically receive e rod, .(11), the outer end of w iich is connected to e crank (12) on the semaphore shalt. Thet endet the rod received in the socket (10) is slotted es at (13). A. pin (14) removably held in the socket v extends through thc-slot in the rod to permit the switch tongues tobe toni oral-ily thrown :Ker by e trein on the main ine approaching e o the pino rating to permit e relativo movement of t e switch bar and rod while retainin g them sg'einst disconnection. As one ineens for automatically locking the rod and bei' in teleecoped position I may use t ie following construction: 'ilie socket ma vided with en a ierture (15) adaptet to reggisf ter with e hole 16) in the rodeo that a aprinp pressed stud (17) carried by the socket may drop into there istering hole and aperture `isis to lock the switc i rigidly in closed position, and prevent the exit ol' a train on the side, track. A heev coiled spring (18) encircles the rod, one en( of the s ring hearingnninstthe end of the'socket on the other and ol.' the springbeerin against the rod. This spi-ing normally teni s to hold the )in (14) at` the in ner end of theelot and suc spring is strong enough to overcome thc weight of the -iwitcli tongueefend connected parts and the friction caused in moving the switch from one posiswitch from the oppoiiite'direction,`

e pro-Y ordinarily the tension ol' the spring' in clfcct converts the sectional telescopic switch har into a rigidyone piece ba r which is swung hack 'and forth by the lever in the usual operation of openiii 'f and closing .the switch.

l\ c will now assume that n train has passed onto t'he spur or side track 13,11, and 'that the hrakeinaii has left the switch o ien. The en inecr'ol a train following tho l"rst train wi l from the signaltl'iut the lswitch is open, hut he may be too close to the switch and triivelin iit too rapid arat-e to apply the brakes am prevent his train lroin taking the side truck. The contact meniwill engage the track nienibcr connected to the switch tongues and force tho track meniber over to close the lwitch and pci-mit the second train w-continue on the inain line. The operation ol' this part of in v iin'ention is as follows. 'lhe switch is iii thc position shown in Fig. 2. 'l`lie contact incinber under tlicpilot is thrown by the cugini-er nml engages the obliqnrly extending: glaive rail to throw it togetherwith thi` `witch longues, toward the switch stand to close the switch.

'lhe nin (I4) travels toward *..ie outer cnil of the slot (l3), thc lot being: pielcriibl) slightly longer than the path of movement. ot' the switch ton vuen. The spring pressed stud (.17) carriei by the socket rides upon the surface ol tha rod until its aperture (15) registers with .the hole (.16) in tne rod whereupon the pinA snaps into the hole (16) and absolutely locks the switch in closed position so that. not even a movement ol' the lever S can throw the )Vlien the second train moves the switch tongues to closed position (the lever remainmer locked in open position) the telescopic the tension of spring: (1H) and ishelil in siii-li position by the stud (i7). ln ordi-i' to rottirn the switch now closed, to open posii lion, it would he necessary to movc the le ver farther in the direction in which it was liist swung by the brakeinnn.

When released, the tenn of the spring at once asserts itself and l either nutoiiiaticsll return the switch open position or w l rotate the scmnre shaft, to closed position providin the .ft operi'itingleveris unlocked. The ookof the er. Etch in closed oeition operntes prevent a trein on the sii e trsck from reering the iimin line and I may so mclose switch haii' nnd rod that no soeces may had thereto without s special key for irince. This nrrnii ment would necessie notifying sii oliicisl und result in the ection -of the careless binkeman. In s this construction is considered to be irscticsble because .of dissrrsnging the in schedule, I may nrrsnge the construci as shown sc ,thst the brskeniiin hfv the of s' crow bnr or other suitable too miiy the spring pressed locking stud (17) out the hole (lo of the bnr where on the ing (I8) wil either sutomsticel y force socket (l und switch tongues to open ition or vii-i rot-ste the semnphoie shaft tion.

The. gliinee.rnil ht bc'locntcd outside the main trnck. Iii present s plicsticn I lieve illustmted s tset mem r comprising n bent or sn upivotslly supported piste (I9) the ree of which normally proects upward et eand csrrics sii enti riction roll thcresr engi of the e, its function ing' to sutcmstieslly w theplste to one or the-other of its exie posi ions after. the plste has assed its l center inone direction or te other. in the oo'ntsct membenis in -its-rsised tion it'will not engsge the tuck-member, trsckrsils or other ohetructions.` In orto permit the engineer to throw the oonmem'ber into operstiv'e position' I ms ride lever (22) to which one end of s lin is connected, the op ite end of the being loosel connecter to the piste (19). :his means he engineer on sppronching tch, can move his lever to throw' cont'sct member down where it will enthe trsck member and close the switch. i obvious, however, that if a trsin is cling st y speed, the engineer will not' .ble to re urn the contact member to :lcxssition between the time when the y i member lesvee the trsck member the time it xesches'the switch rails. efore I provide s resetting member, one aliment ofv which consists of s rsil (27) inclined iipwiirdl in the direction of travel of the engine.` 'l` iis rsil extends in allnement with the psth of trsvel of the contsct memtlie track member. As the contact member lesves tlie trsck member, it enfxg'es the inclined resetting rsil (27) sm is' thereby thrown peut its desd center whereupon the spring 1)'will reise the contact member to its upwsnlly inclined position. I msy also opposite side of the switch to reset s contsct member which may have been thrown down hv sn engineer spprosching the switch from the op ite direction (shown b srmwz). It is o course unneceess for t e engineer o throw the contsct mem r into o rstive ition even though the switch is open, irst, because there is no track member to be l operated end secondly, if the contsct member remained in its lowered position it would l engege snd dsms i ns well se itselt'..v irdly, when the swi is g open, the telesci-ipic switch bsr is slwsys in j extended position even though the lever (8) me.) be locked. As the trsin trsveling in the direc' ion indicated by thesrrowzI s prosches i the switch tongues, the snges of t e wheels l will crowd the switch tongues over to closed i position forcing the socket (l0) on to the rod (11) the pin (H) moving in its slot (13) against the-tension of spring (18) until the pin 17 registers with the hole l5, whereupon the pin will enter the hole und lock the switch in closed position.

The intervsLof time between the throwing of the conte/ct member into oper-stive position snd its return to raised position is extremely short especially when the trein is running st's high rste of speed. Nstursll if there is s sitive connection between t lever (22) and the'contsct member, tluen neer will hsrdly hsve time to release e ver before it is thrown back by the' 'resetting 'of the contact member. It'might hs 'pen thst the engineer might get in the way olf) the lever or m' ht not release it in time und the blok lssho the lever would inflict greet initiiy, to svoid -which I provide s loose connecion between the lever snd the contsct membetnvhichfwill permit the ooirtsct member to be thrown downinto operative position by the engineer, but will not rmit t e resetting of the contact member rom thev csb; As one 'su mesns .I may provide the forwsrd end of the'link with an sgverture (24esdspted` to locsted sest upons pin (2 tween the arms o a yoke (2o) csrriod b the plete (19) intennediste its ends. The ink is received and guided between the srms o'f the yoke (26) snd ol' s second unsesting yoke (28) proect' (19 eforwsrd end ofthe link insy 'inherently resilient so'thst the spertuie is normally held in place 'on theepin. When provide s similar resetting menibcr on the.

the engineer throws the lever (22) to move the contact member into operative position draw theflin backward and when the aperture (24) in thelink registers with the pin y (25),A theinhcrent resilience of the link will cause it to seat over the pin, thus restoring the engineers control of the contact ineinier.

It is evident that changea mi ht he inode in the form and arrangement o the several parts described without departing fromthe spirit and scopo of my invention. vHence, 1 do not wish to limit myself to the exact construction heroin set-forth.
