4inoveanent trein the device to a onto the siding,jor other track,

eThis invention relates to improvements in t; operated railway switches and .dc-'signed for automatically a moving train from one 'track to y'ithout marinai assistance.

the invention consists in locating 'een the ral outside et the saine, a d rice which is adapted to he streelt hya or projection carded on the train. rihe .n nent ci this part 'transmits a memher which is located so to he held down hy the tread portion oi? the wheel during the passage ei the train into the switch. The moveme oi the device and member throw the switch eo as to permit the train naive mld the switch .in this open position nntii the last car has passed thereover.

lt is the usual enst-ein, in the operation of switches, to transfer a nio-ving train from one track to another, for one of the trairrV to unlock the switchand throw it hy ing to a stop, and to permit the automatic ciosureafter the train has entered the siding.

in the drawings iorming part of this ap` plication,-Figure 1 is a plan View showin the switch in a closed position, that is withthe main line open. Fig.' 2 is a View similar to Fig. l with the switch opened and the main line closed. Fig. 3 is a side elevation showing the relative arrangement ot' the projection on al'portion of theengine and the depressible bar operable therefrom. and by which the switch is operated. 'Fig. 4 is a' detail Vlew in elevation, partly in section, onv

-line 4 4, Figi'i, which shows the. har 'that is operated` by the projection on the engine, and before the car-Wheel strikes the second har for holding the switch open. Fig. 5 is a detail View` in elevation, partly in section on the line 5-5, Fig. 2, which shows the position of the parts with the f car-wheel in place on the second bar that holds the switch open. Fig. (i is a transverse sectional View on the line 6--6, Fig. l, illustrating the position of the operative parts in their norin-ai position with the switch closed. Fig. 7

tive devices placed between the rails and sln'i'wing the' switch closed. Fig. 9 is a View similar to Fig. 8 showing-the switch opened. Fig. i0 is an enlarged View oit' the operative part' within the casing. Fig.- ll is a transverse, sectional View on the line ll-ll, Fig. l0.' Fig. l2 is an enlarged detail View showing the operating lever, the form of slot therein, and the position the pin occupies in the slot both in the open and closed position of the switch points.

Referring to the drawings, @designates the rails oi the main track or line; L and c the movable point or tongue members of the switch rails/; c an operating lever having an angular-shaped slot f in the inner end thereof for receiving the pin f/.which extends upward' from the rod z that con in a closed position. `With the pin in this position it is acting toward or against the pin j. The' right-hand-end of the slot is formedl on an arc of a circle, the center of which is the pivot-pin j. Then the `projection lwon the engine engages the bar o and moves -the yhar lc downward flush 'wilh the upper surface of the rails (see Fig.',7) the lever c is operated about its pivotI y', and during the first portion of the movement or travel, the pin gf 'will remain stationary and also the bar l1, because the right-hand end vthe position of the parts when the oi' the slot. is 'formed on an are oit a circle whose center 1s the pin y. During the latv ter part of the lmovement of the levere, the

pin g and bark are'moved so as to move the points Z) and c into the position shown in Fig. 2, that is With the main line closed and the switch open. As the inner end of the lever e travels from the position shown in 1 to that shown in Fig. 2it is clear that the pin g and bar h will be moved and the switch' points opened. The left-hand end of th' slot f extends practically parallel with the sides of the lever f and intersects or leads into the right-hand end of the slot which is formed on the are of a circle ing z' at the point y' and is attached to theA deprcssible bar ll: by means of the link m', the outer end ot'the lever e being attached to the bar by neans of the flexible connection A bell-crank lever s is interposed between the connection 7 and the bar 0 and pivoted to the casing s1 at s2.

5* designatesa link `wl' 'ch supports the opposite end of the bar in a 'parallel ruler manner. v

.1f designates the spring' which is attached to the operating lever@ and a fixed part of the casing z'. rthis spring serves to hold the bar 0 elevatedl as shown in Figs. 3, 4, and 6. The bar 0 is placed in the casing member s1 with its upper ,surface normally projecting above the upper edge 'v a slight distance.

The link m causes the bars o and /f to inove together: because when the bar 0 is struclcby the projection il; on the engine this bar is depressed which causes its inotion to transmitted to the lever e by means of the connection 1'. rThe link m is also attached to the lever e, and the bar Theret'orewhen the bar o is depressed the bar L will be simultaneously moved downward. Therefore, when the projection fw on the engine, (which is shown at the left of Fig. 3,) strikes the bar o. the bur /u 'falls 'downward and forward into the position shown in Fig. 7, (that is it falls from the elevated position shown in Fig. 6 to the flush position shown in Fie'. Tl), the wheel o the engine, shown in dotted lines in Fig. 7, holding the bar /r downward, thus openinc' the switch Joints` as shown im Fic. 2.'

The pin g, meanwhile, has traveled trom its positionshown 1n Flg. 1 to the opposite end @oserei projection w has left the bar'p, the weight. of t-hetrain Serves to hold the switch open, and the passing of the last car-Wheel from the rear end of the train permits its. en

werd return to the closed position shown in Fig. 1.' The bar lo that is attached to lever c is provided with notches ai and y, and these notches adord shoulder por tions e which rest on projections 3 and Lt..

These notches and shoulder portions permit the bar 7c to move backward and forward and up and down;- i

Referring to thev modiiioations shown in Figs. 8, 9, and 11: 5 designates e. ons which is located between the rails of 'the track and which serves to cont .n the operative parte for moving the sw; in this "Cill.. respect it diil'ers from the construction just described in which the operative parts are located outside of the rails. Referring to the details oi this modifi cationfwt` indicates a lever. which is pivoted to the 'upper pord tion' of the box 5 and this lever is adapted to be struck by the projection 7 on the moving train, Attached to the lever 6 is a har 8 that is provided with a pin Si which 'works in a slot 10 of the lever 11, the outer end of 'the lever being provided with en. outwardly.

opening slot or recess 12 which receives a pin on the bar 13, Whichbar is connected to the movablemernbers b and-c. '1" t.; lever 11 isv .pivoted to the box 5 at ist and is attached to the' parallel arranged bar 151W means of4 the link lo, the bar l5 being located adjacent the rails a andv engaged by the tread portion of the ear-wheeis in order to holdthe switch open While the train is passing, in the seine manner as described above in connection with Figs. to il. l'wfhen the projection 7 strikes the lever 6, the har 8 is moved in the direction of the arrow l? causing the pin`9 on the lever 8 to slide down .the slot 10, which, being an inclined one, .causes the inner end of the lever 11. to be moved away troni the pin 1S on the bar 13, and out ot the slot 1'2. This action permits the har 8 to move the bar 13 into the open position shown in -Fig. 9. it the saine time the bar 15 falls into a position that is iush with the upper surface of the rails. The

` wheels of the train o't cars now engage the bar as before described. and hold the switch .1 'r v1 points b and c open. Ihe 'spring 19 will return the switch to the closed position att-er the train has passed into the spur-track. During this return niovenient the pin 18 re enters the slot 12 and the pin 9 moves to` the opposite end ot the slot 10, whereby the switch is held locked again in its closed position, as shown in Fig. 8.

It will be noticed that in 8, 9, and 10 the piece G isprovided with an inclined edge G1 at its lett side, the purpose of which is to throw the switch pointsb and c into 130 of the slot f, as shown in Fig. 2.
