RAILWAY SWITCH;

Application iled llmrei'nber14,` 1925,;Seria1 No. 53,123.5, y n.

Theobject of the inventionlis to providel A iurthenfobject is to provide track,`v structure includingy,devices :tor engagement by either,pilotvwheel,said devices control ling agplurality: of pivoted elements freely mounted with reference to each other and interengaging .as described below, for throwing the .switch point to the position 4required for following k,the straighttrackor for rounding acurveor` the like,v

A still `further object .is to provide `retaining means forthefswitch point,v

With the foregoing and otheruobjectsvjn view, theinvention consistsin the novel `con#` struction and arrangement of elements described, illustratedfandclaimed, it being understood that Vmodiic'zations maybe made within the scope of the claims without departing from the spirit of the invention.

In the drawing forming part of this application,

Figure plan.

Figure 2 is a longitudinal section, the section being on the line 2 2 of Figure 1.

Figure 3 shows the car carried means in side elevation, with a portion ory a car truck and wheel, in dotted lines.

Figure 4 shows the car carried devices in front elevation.

Figure 5 is a diagrammatic view of the circuit for .controlling the magnetsv by which the' respective pilot wheels are operated.

The straight rails of a track are designated and 11, these railsbeing mounted on ties 12, and the rail 11 merging into deiiected rail 13, for a curve, siding, or the like, and rail 13 being complementary to the rail 13.

On one of the ties 12, I pivot at 14 a pair of bars 15 and 16 having their forward ends pivoted at 17 to a transverse bar 18 extend- 1 shows the track structure in top ing perpendicularly with reference to theV rails 10 and 11.

A lever 20 is fulcrumed at 21 on one of the ties, and is pivotally connected at 22 with the bar 18 and is operated thereby when one of the pilot wheels, referred to be- 10W, engages the bar 15 or 16 and throws one of the l,bars outwardly with reference toy the adj acent track rail.k

i The; lever `-20 hasgavtaperedv. endl portion@ 4 terminating m a point, 21, andthelatter engages a ii-shaped cutaway portion 25 in aj pivoted .'arm25. -I 4ll'iisla-rm last namedhas a tareledendf the 11011111 0f the .arm engaging i; the cutaway portion 426 in switch point ,lever 27, pivoted atf28, on one oli theties.

VThe lever 28 is. connectedvfby meanspt pivoted link L29 with Switchpoint `3() and, operatesthe. latter in an obviousmannen` the movement of this element-being limited by short rail or stop -31.

In order.` to retain Switchpoint 3Q in the position in `which itis thrown, f1. plOVCle .a retaining` vor locking device ,desighated l and provided with aslot through which bolt 37 pflssesinteonepof the teSQlZ T011@ end of member 35 is'tapered as shown at .35 and this end engages a V-shaped cut'-,

away portion 38 in theend of element 27, 7- i' i the other'end of element 35 havingV a bore'39 therein for the reception of. one end of a coiled spring 40, the opposite end of the springbeing received by socket 41 in pivoted socket member 42. The expansion spring imparts end thrust to element 35 and tends to hold switch point lever 27 in ythe position in which it is placed.

The car carried devices include levers or arms and 51 pivotally mounted at their upper ends, these elements being downwardly deflected at 50 and 51 and mounting brackets 52, and supporting in connection with these brackets7 axial members 53. Pilot wheels 54C are mounted on elements 53 and each includes a flanged portion 541, the latter engaging the edge of the track rail, at the head thereof, and being adapted to engage pivoted bar 15 or 16, as the case may be.

The levers 50 and 51 are normally held in an upper and inoperative position by means of springs such as 55, but arms 50 and 51 are thrown to operative position by vertically movable bars 56 having upper ofi?-r set ends'57 constituting armatures for cooperation with the magnets 58.

switch point 30, will be operated, and the .switch point will be retained in that position by means of the retaining element 35.

In Figure 5, the electric switch 60, constituting a controlling device for determining the direction of travel of the car, cooperates with switch points 6l and 62, and has connection by means of wire 63 with battery 64. IThe other terminal o'i'- the battery is connected with wire 65, the latter leading to one of the magnets 58, and a wire 65 leading to the other magnet 58 which is in electrical connection by means of a wire 66 with contact point 62.

Vihat is claimed is z l. The combination'with a switch point, of a. switchk point operating lever, a pivoted arm freely engaging said lever and controlling the movement thereof, a pivoted lever i'reely engaging the pivoted arm, said arm having detached endwise engagement with the levers and means adapted for operation by a car carried device, ror controlling the lever. e

2. The combination with a switch point,

, of a switch pointoperating lever, having recesses lin opposite ends thereof, a locking device engaging one of said recesses, and .a pivoted arm freely engaging the other recess and controllingthe movement of the switch point lever.

3. The combination witha switch point,

of a switch pointoperating lever, having recesses in opposite ends thereof, a locking device engaging one of said recesses, and a pivoted arm freely engaging the other recess and controlling the movement of the switch point lever, and a spring `for imparting end, thrust to the locking device.

a. rhe combination with a switch point, or' operating means therefor including a plurality or' levers pivotally mounted in spaced relation, and in alinement, a pivoted arm mounted between approaching ends OI the levers, and 'freely engaging said ends, one ot the levers having operative connection with the arm, and said arm having operative connection with the other lever.

5. `The combination with a switch point, of operating means therefor including a plurality of levers pivotally mounted in spaced relation, and in alinement, a pivoted arm mounted between approaching ends of the levers, and freely engaging said ends, one of the levers having operative connec tion withV the arm, said arm having operative connection with the other lever, a loching device in alinementyat times, with one ot the levers and freely engaging that lever, and a spring for imparting end thrust to the locking device.
