To all whom it may concern:

7 Be it known that I, Winn/tea J. Winona, a citizen of-the United State residing at New York,county of New York, and rotate of New York, have invented certain new and Automatic St-o for litaihvay-Train'af ful y ing Mechanism,

resented in the fol owing eacribed and rep lficatlqn and the accompany ng drawformmg a part of the same.

mentsin automatic stopping mechanism i501- railwa trains.

lnt e-.o oration of rdilwave, and articularl in t operation of electrical y operat railways, on which high apeed and fre- 4 went service, are maintaingd, it is desirable t at the'trams be provided with stopping. devices which aha] operate to prevent a train'trom using a signal which in in atop positiomt will be which shall be of such a character as to prevent. the driver of a train from runnin? by a mi nal which is set against him wttiuut hia eing apprised of that fact.

A further objet-t'of-the invention is to produce an improved automatic stopping mechamsm for .rallroadtrams which shall be 01' such a character that the driver of the train is prevented from runningby a signal which is set against him without being apprised of that fact but which also enables him to pass such a signal if the conditions render:

. unnecessary.

The invention further extends to certain improvements in details of construction by which the objects referred to are carried into efl'cct.

Referring to the drawings, and more par- I ticnlarly toiFig. 1, the track-rails are ind.- cate at land the working conductor at 2.

4o changing or'shiftin who can so the t dcscription, such, for instance, as a thirdrail or an over-head conductor, the third- "rtnl type, however, be ng shown. It will-be understood that the rilnary function of this 5 conductor is to supp y the current which furniahcs the tubtive mwer for the motors of thetrains,*wh ere t to invention is employed,

in connection with electrically o 'ierat ul trains. An electric-locomotive or car is indicated at 8, said locomotive or car being;

represented as attached to other cats, indicated at 4.

- ln'what are regarded as the best construe-t 'tions for carrying the invention into eflect, the working-conductor will embody what may be termed a controlling section of short length, "this section being indicated at 5.

. The purpose of this section is to control,

through proper agencies, the stopping devices on the car, locomotive or t-rain,.ut the time a signal inset against the driver-of the tram, and while the lcngtlrot' the controlling scction may be varied, it should not be longer than the length of a train, and, in thebest forms of constructions, it will be less in length than an ordinary car; it being understood that the term car as used III the specification, is meant to include any form of car or locomotive. In the best conso structions embodying the invention means will be employed for rendering this controlling-section operative or inoperative :with. respect 'to the stopping devices to be hereinafter described, and these means are,

38 in the construction ilhhtrated, of such a character-as-to be controlled from the signal employed. According to one form of constructicn illustrated (see Fig. 2) this controlling scction is made inoperative by 0 5 its position. When the invention is come into eilect by a construction in which the controlling section is made inoperative by change of position, the conttnuit of the working conductor may standing thistchange in position bvsuitahle connections. In the construction illustrated in Fig. 2, this is etl'ected b connecting the ends of the section with t e conductor by flexible bonds 0.

Referring to the construction illustrated;

in Ft land 7, thecontrollingi-scction 6 of -.rail is carried by inaa carried b rackets 8. These brackets ma be provi ed with feet 9 arranged to ali e between ways 10 formed on; a suitable base which supports the brackets, so that the brackets. It will de jtrat 'in- Figs. 1, 2 and 7 to 10 inclusive the motor is. operated on a closed circuit which- -to remain undisturbed, notwith atom! of a, usual form) these insulators being in turn brackets may be moved to carry the movable secttonmto and out of line with the workeonductor.

in v fivhere the invention. is carried into'eflcct by theempl oyment of a movable section, a suitable pottllltmlltg mechanism will be used ';.i'or deternnnin the position of the section. Whilc'tlusn ec ianism may be:varied widely in its construction,- as shown it includes a motor, lndicated at. 11*, the shaft of' this .motor being provided with a gear '12 in mesh with a gear 13 on a shaft 14 extending along the movable-section, as illustrated in Fig. 2: Tht'sishaftmay be provided with n plurality 19f eccentrics 15, one for each of 'the carrymg brackets for the controlling, section 5, the strap 10 of each eccentric be-' mg connect-edby a rod 17 to a socket 18,-

Where a movable controlling section, the

movement of which is determined by a 'posi-' honing-device is employed, the osttioningdevice may be under the cont-ro of the sig- .nal. The nieann by which the signal contools the positioning device when tltclsignal is employed'for this purpose, may be varied In the particular construction illusmay, as shown (see Fig. l) derive its rurrcnt from the workingconductor. In this figure, the wire leading into the motor is marked 19 and the 'round wire leading from the motor is mar ed 20,, it being shown as connected to one of the track rails.

vThis circuitcontroller (see Figs, 16 and ii) may be conveniently mounted ma box 22 carried onv a pt'st'Lil which support-s the slight], the signal chosen for the pu pose of ii u tration being the ordinary semaphore. the arm of which is indicated at 2-1.

Vtth the construction apparent that when the motor shaft is turned, the brackets will he hemotc'r may be provided with suitableso far descrihcdfit will be understood that when the eemaphore arm or other form of "ttignttl is act at'danger. the circuit through the motor will be open. thin cutting (ill'lllt' J'ttt'tcltt mlliblictl to'the motor. The rin Bl will, therefore. be frce'to operate llllt wi turn the motor shaft. The rotation of the motor shaft by the sn'ing will turn the o-hnft 14 which thrcugi the eccentric.-: and connections (lPtl'l'X'tl' will slide back the. bracket-. carrying the movable controlling nectien from the pmition t'lltlWll in Fig. 7 to the position shown in Fig. 9-. Instead of employing a sliding construe- -tion-for the brackets, the brackets may beconstructed as bell-cranks (see Fig. 10) one It'll) of thebell-eranks being marked 32 and the other marked 38. 'l'he e bell-cranks nuiybe pi t'oted at 84- to etandarth Bound theconueeting rods 17 of-the eccentric straps may be connected to the arms 33. With this form of construction, the brackets, when the eccentric shaft is operated will be. rocked to shift the position of the movable controlling section.

In conatructious embodying the invention,

the operation of the stopping devices to be fore, lie employed to place saidatopping heroine r described will depend upon -\'ary-in to electrical relation offthe stoppingwevicea withncspect to the rorkingcont actor, and tstlllttlll' means will, th'erethere a ncies. In the particular 'con ti'uction il t'tstrated. the stopping devices are nude etiectite through both l'ltts't' agencies.

While the particular cottell'tlt'lititt of stopping devices employed may be varied, in the heat constructions. they will include an actuator which may be electricallyoperated.

' In the particular construction illustrated,

Referring to this figure, four collectors 3tare shown, inasmuch aofour col'lcctors would line wire is indicated at l8 and from thie wire lll't llt'llt'fi lt lead to two of the collectors 36 and branches 50 to the Olin-l two collectors 36.

The return from the magnet to the battery is b the wire 68. It is apparent that when t is local circuit is closed and the magnet 57 energized, the locking bolt will engage the notch in the actuatorand prevent the movement of thermal even though the circuit through the solenoid 42in: interrupted. f
