4|, the

arcuate ring segments

42, 43 and the web portion 44 for resting upon the insulated plate I6. A straight rail portion 45 extends upwardly from the web portions, together with an inner frog point 46 and the

short rail portions

41, 48 which respectively form parts of the track for right-hand and left-hand turnouts. The rail portions 45 and 4l provide switch points for through and right-hand turnout, respectively. These short rail portions are also connected to the

segments

42, 43 to stiffen the assembly. This part 40 is also illustrated as being in one piece, formed by molding a plastic.

Where the switch is constructed for toy trains having large drive gears adjacent the wheels, as shown by dotted lines in Fig. 2 the short rail portions may be cut away at the guard-rail sides, to allow free passage, as shown in the figures.

When made for toy trains, the distance between the tops of the rails and the top oi the plate l should be equal to the height of

normal track rails

20, 2|; and hence the intertting of the web

portions oi parts

30, 40 permits a minimum total height with a maximum thickness of the web portions. To this end, the

slots

35, 36 represent cutting away the webs in part 30, and openings 49 occur through the part 40.

When the

parts

30, 40 are fitted together (Fig. 2) the web portions lie in the same plane so that the upper surfaces thereof define the bottoms of grooves provided to receive the wheel ilanges, and the tops of the rail portions likewise lie in a plane and serve to receive the wheel treads.

In the illustrated form, with a central third rail, the third rail 50 at the approach to the switch is extended by a bar which is connected electrically and mechanically by a. post 52 and screw 53- to the insulated plate I6 (Figs. 1 and 2) this bar 5| thus overlying the web 34 of part but terminating short of the path of train wheels which are making either turnout; with lateral insulation 5|s to prevent contact by the metal train wheels or auxiliary electrical equipment as the train is making a turn out. The

stubs

54, 55 at the turnouts are extended by bars 56 which curve toward the

rails

20, 2| so that their ends are closer in the horizontal plane to the end of bar y5| for decreasing the gap; the bars 56 have their tops curved or beveled downward at the free end to give a smooth sliding surface for the collector brushes; and the bars 58 are connected by similar posts 52 and screws 53 to the plate I6. The stub 5l of the through track likewise is extended by a bar 58 similarly connected by a post 52 Vand screw 53. When the structure is provided for trains having a single collecting brush, or with two brushes spaced a lesser distance than the gap between bars l5| and 58, a metal contact rail portion 60 is carried by the part 40: the part 30 carries at a point outside of wheel tread or ange contact, an insulated connector spring having one arm 6I to engage the bar 60 and a second arm 52 to engage the rail portion 58 when the parts 30, are in position for straight-throug passage of a train, whereby the rail portion 60 is energized, and it will be noted that if either

part

30 or 40 is in position for a turnout, the connector spring opens the connection so that portion 60 is not energized, and hence this portion 60 does not cause short-circuiting upon passage of the train for a turnout.

Beneath the plate |0 is a spiral coil spring 65 having its central portion guided by the bridge I3 and having its ends extended upwardly through holes 61 in the plates I0, I6 and insulation I5, with the upper terminals turned toward one another and engaged in the

parts

30, 40. This illustrated engagement is at the frog side of the axis, so that the eiect of the spring is to cause the switch point ends of

rail portions

31, 45 to move into engagement with the rails 2 I, 20.

A slot I0 in base plate I0 underlies a wider slot 'Il in the insulated plate |6 and the sheet |5. A switch link 'I2 has an upturned end 'i3 positioned between the

parts

30, 40. The other end 'I4 of the link is secured to the switch actuating slide 75. The washer 'I6 nts the end I3 and holds it above the plate |0.

The switch actuator and lock acts upon the switch link 14. In the illustrated form, the parts are within a housing B0 having the three electric switch levers 8|, 82, 83 on its top, and a slot 84 through which extends the actuator 85 for manually actuating the switch. The housing is positioned on the plate I0, and the latter is dimensioned and arranged so that the housing is cleared by a passing train. The illustrated form of plate I0 permits additional like switch units to be connected at the ends of the tracks formed by the rail stubs, with clearance between the switch parts themselves, and clearance by the trains.

With the illustrated parts, the switch can be moved selectively to any of its three positionsA either by mechanical movement of the actuator by hand, or by electric means.

Within this housing 80 is mounted for sliding movement the slider 'I5 which has a slot 86 in its top (Figs. 10 and l1) into which the lower end of actuator 85 extends. The slider has a lateral extension 8l having a hole 88 in which loosely nts the unlocking lever 89, and also having the down-turned skirt with the locking lug 9| which cooperates with the locking piece 92 fastened to the top of the plate I0, and having end notches 93.

The coupling rocker 94 is pivoted adjacent its lower end to a ange 95 turned up from the plate I0 and to the piece 92. Its sides have ve openings 96 each, the center opening of each set being covered by a green light-lter, and the two end openings of each being covered by a red light-lter: these openings being selectively revealed in three openings 91 in each side of the housing 80 as the rocker is in one of its end positions or in its center position. The actuator 85 ts closely in a hole in the rocker: while the unlocking lever 89 is received in a slot 99.

For electrical actuation, a tube |00 supports three axially spaced coils |0|, |02, |03 and guides the iron solenoid core |05 which is rigidly connected by threaded brass rod |06 to the actuator 85: the core can be adjusted along the rod so that when the core is drawn within the central energized coil |02, the actuator is in a predetermined corresponding position. Electrically, one terminal of each coil is connected to ground, that is, to the plate |0. The other terminal of each coil is connected to a selected one of the switches 8|, 82, B3, and thence by conductor |94 to the insulated plate I6. When remote control is desired, the conductors |08, |09, ||0 can be carried to a panel having switches la, 82a, 83a, and thence by a conductor |04a to the general conductor which leads to the central third rail,

i' in the illustrated form.

IfI itisinow desired toreset the track switch forfcentral passage'the `actuator 85 is pushed backs toward-the center, either'manua'lly orby closing switch 82v or switch 82a. The rocker 94'is immediately moved; but the actuator 85'has-an initial free movement-'in the slot 86 of'slider 15': the rockerfmoves lever 89 so that the* left end lof the-liften I I5 pivotsonthe cam piece I I6 and raises the extension 81 and releasesthelug9| from its vlocking'notch93- The action of spring 651and-of theactuatornow moves thev part 40 ba'ck'again; until Switchpoint 45 engages rail 20 and Switchpoint-41 is clear; and the vrail portion 45`also`passes to alinementwith the stub 24 and contact rail 6|)v encounters spring arm 6| and becomes energized. The coil |02 has been movingfthe core |05toward`the left, thus activating the actuator andthe yrocker 94 initially; and the combined action ofthe spring 85 and the core |05 cause the resetting of the switch points together with a movement of the slider v15' so that the lever- 99 isvcarriedtoftheposition of Fig'. 12.v

The rockerA openings 96' show red-green-red again.

the

third rail portions

60, 58, so that 60 is deenergized. The holes 96 of the rocker show green-red-red through the housing 80, indicating a turnout to the left.4

Return from left-hand turnout is similar to that from right-hand turnout. The locking lug 9| is lifted by the action of lever 89 and lifter I I5, and the slider is thus released.

While one preferred form has been illustrated by way of detailed practice, it is obviousv that the invention is not limited thereto, but many forms may be employed within the scope of the appended claims.
