TOY RAILROAD.

Application led October 27, 1925. Serial No. 65,104.

The present invention relates toV toy railroads, and is more particularly directed toward the provision of a toy electric railroad in which two trains may be operated so that one train is stalled until another train enters upon or crosses a predetermined section ot track.

The present invention contemplates a toy electric railroad made up from a number of l0 separable sections having one or both of the track rails of certain sections insulated from one another and from the adjacent track sections in such a manner that a dead section of track is provided on which a train will stall when run onto it, this dead section be ing associated with another section so that a train in said other section ot' track will ground one of the rails in the stalling section and permit the stalled train to start.

An object ot' the invention is to provide a number ot' track sections, normally interchangeable with other track sections, but whereon one, or both, of the track rails are insulated, and to interconnect these sections and insulate them from the adjacent track so that the operation above set forth may be accomplished.

Another object ot the invention is to include in the track layout a piece of special track such as a turnout, switch, or crossing which permits trains to operate in different paths over the same point, whereby a predetermined sequence of operation of trains over switches, turnouts, loops, and crossings may be maintained.

The invention may of course, be applied to various complex arrangements of track, only4 a few of which will be disclosed herein in detail. Several ot' these forms or embodiments of the invention are shown, for purposes of illustratiomfin the accompanying drawings, in which:

Figure 1 illustrates a tangent provided with a track arrangement on which a stalled train is started when another train comes up from the rear;

Figure 2 illustrates a main line track and siding provided with a track arrangement on which a train stalled on the siding and headed in one direction, is held until a through train, going in the other direction, passes over the main line track;

Figure 3 illustrates a. main line track and siding provided with a track arrangement on which a train stalled on the siding and Figure 7 illustrates a form of insulating I pin suitable for insulating the rails of adjacent track sections. l

In Figures 1, 2, and 3, only. a portion of a track system is shown, it being understood that the track shown forms a part of a system ot' tracks commonly used for operating toy trains. This track system may be made up of any convenient arrangement of straight and curved track sections, switches, crossings, etc., as is well known. The commercial units of tracks for toy electric railroads are made up out ofsheet steel rails and cross ties, the central or third rail being insulated from the ties and other rails. The power' source is connected to the third rail and to the track railsand cross ties. According to the present invention these standard parts are utilized as much as dpossible, a few special parts being inter-pose and suitably insulated.

According to the showing in Figure 1, a number of sections of standard insulated third rail track 10 are placed at the right hand end of the tangent. After the train passes over these ordinary sections, it passes onto a number of sections of track such as those shown at 11,.11b, 11, etc. These track sections are structurally interchangeable with standard track sections, and may be substituted for them in a track layout. In these sections one of the track rails 12, 12", 12C, etc., is insulated from the cross ties 13 by insulations 14. similar to those used for the third rail. They are connecte-d together by the usual steel connecting pins. The insulated track rail 12El is also insulated from the corresponding track 'rail 1.5 of standard section 10 by an insulating pm 16, such as shown in Figure 7. This pin is removably secured in the hollow ends of the sheet metal rails. The oncoming train proceeds over these sections 11", 11", and 11c in the usual manner, the running gear of the locomotive being grounded through the uninsulated track rails 17, 17, 17", and 17".

The momentum of the train will carry it along the track and onto sections 18, 18", etc. These sections have track rails 19", 19",

etc., which are insulated from the cross ties' 2U by insulations 21 in the same manneras the track rails 12, 12", 12", etc., and are conductively connected to them by the usual metallic pins. The other track rails 22, 22", etc., in the sections 18, 18", etc., are also similarly insulated from the cross ties 20 by insulations 23. It will thus be seen that the sections 18", 18", etc., have all three rails insulated from one another. The last section of this three-rail insulated track is insulated from the track rails of the adjacent standard section 10" by insulating pins 24 and 25, while the track rail 22a in the first section of this track is insulated from the uninsulated track rails 17", 17", 17, etc., by an insulating pin 26.

Vv'hcn the train proceeds from the sections 11, 11", 11C, etc., to the sections 18, 18", etc., the wheels pass from the grounded rail 17c onto the insulated rails 11", 22", etc. As both sides of the running gear of the train are on these insulated track rails, the motor stops, and the train is stalled.

N ow when a second train comes from the rear and enters onto the section of track composed of the special twosrail insulated track sections, and marked 11", 11", 11, etc., the running gear, which is grounded by uninsulated rails 17", 17", 17 c, etc.,will ground the other track rails 12", 12", 12", ete-19, 19", etc. This grounds the running gear of the stalled locomotive7 and the stalled train proceeds out of the section, formerly dead, and goes over the standard track 10". The rear train runs onto the dead section and stalls as above described.

No attempt is made in the drawings to show the actual number of special sections to be used in a particular layout. The num ber will vary according to the length of the commercial sections used, the Speed, acceleration, and coasting ability ofthe trains, their length, and the grades and curves in the track. For this reason the reference characters for these special. sections are given subscripts a, b, c, etc.

Figure 2 shows an arrangement wherein a train going to the'left is held on a siding until a train Goes to the right through the main line trac The train comes from the left over standard track sections 30 and passes through the switch 31 onto the siding 32. This siding may have a section of standard track as shown at 33, if desired, and it is provided with a plurality of special three-track insulated sections 31h-,34, similar to the sections 18", 18", etc. Pins 35 and 36 insulate the track rails of the sections 34 from the corresponding rails of section As here shown, a section of special twoerail insulated track 37 is arranged tothe left of sections 34. The grounded rail 38 of section 37 is insulated from the adjacent rail of section 34 by a pin 35). Another switch 40 is arranged beyond the section 38 so that a train may pass through the siding' and back onto the main line track at 41. The insulated rail of section 37 is connected with the corresponding rail of section 34 and with the inside, V-shaped rail 42 of the switch 40, this rail being insulated from the cross ties of the switch, as shown at 43.

'Themain line track between the switches 31 and 40 may be made up of a number of `track sections. As here shown, a standard track section 44, having two grounded track rails, is placed adjacent the switch 31. The remaining sections ot' track, numbered 45, are provided with two insulated rails similar to those in section 11". These sections 45 have an insulated trackrail 46 so placed that it is connected with the V-shaped rail 43 of the switch 40. An insulating pin 47 is placed between the insulated rail 46 and the corresponding rail of standard section 44.

From an inspection ot the drawings it will be obvious that the rails 37, 40, and 4G are completely insulated. lVhen a train going to the let't passes on to the siding 32, it will run onto the dead section 34 and stop. A train coming from the left will pass through switch 40 and remain on the main line track. As soon as the running gear of the locomotive touches the rail 43, this rail becomes grounded and thereby connects rail 37 to the grounded side of the system. This` energizes the motor of the stalled train and permits it to start. This motor will have power supplied Vto it as long as the train remains on the two-rail insulated track sections 45. It will thus be seenJ that the through train passes over the main line section without stopping and that the stalled train is allowed to start as soon as the through train strikes the switch. ing up a particular layout it will of course be understood that the design will provide for stalling the train far enough back of the switch 4() so that the through train will clear thel switch before the stalled train can 'reach it.

Figure 3 shows a track layout arranged for operating trains from left to right. A train may be passed by the switch 5t) onto the siding 51, or it may be passed directly through the switch along the main line track 52. Standard track sections 53 may be used ahead of the switch which may he standard. The first sections of the siding may, if desired, be made up of standard third-rail track as indicated at 54. Other sections ot' track in the siding are, as here shown, made llt',

In makup of special three-rail insulated track, as indicated at 55. The inner insulatedrail 56 of these sections is insulated from the corresponding rails of adjacent sections 54 and 57 by insulating pins 58 and 59. The other rail 60 is insulated from the corresponding,Y rail of section 54 by pin 61. The sections of track between the special three-rail insulated sections and the switch 62, as well as this switch, are made with one rail insulated, as shown at 63 and 64. One or more of the track sections to the right ot the switch 62 is composed of special two-rail insulated track, as indicated at 65. The insulated rail 66 of these track sections is conductively connected with the rail 6() ot' sections 55 and is insulated from the sections 67 by pin 68. The sections ot' track in the main line 52 of this layout are made up of standard third rail track.

rllhe arrangement shown in Figure 3 operates as follows: lVhen a train is switched onto the side by the switch 50 it runs onto the sections 55, whose track rails are insulated, and then stalls. When another train is sent through the main line track, it runs past the switch 62 and grounds the rails (i4-66 by its running gear. This connects the motor in the stalled train on the sidingr and permits it to operate.

Figure 4 shows an arrangement of track permitting the train to pass around two loops in the form of a F igure 8. As here shown, the right hand loop is composed of a pluralityy of standardy one-rail insulated track sections 70. A left hand loop is composed of a number of similar sections 71 and a number of special sec-tions shown lnore in detail in Figure 5. These loops are connected by a crossing 72.

ln Figure 5 a number of special two-rail insulated track sections 73, 73", etc., arev shown at one side of the crossing and a number ot special three-rail insulated sections 74", 7 4, etc., are shown at the other side of the crossing. In both cases these special sections are included in the left hand loop.'

rThe inside track rail 75 of the sections 73, 73, etc., is insulated from the cross ties 76 by insulations 77. The rail 75 is also insulated from the adjacent rail of section 71 by an insulating pin 78. The other end ot the rail 75 iscrmductively connected with the corresponding rail 79 of the crossing 72. rl`his track rail is V-shaped and connects with the other side of the crossing. lt is insulated from the central supporting member 8() of the crossing and the adjacentcross tics 8l and 82 by insulations 83. The inner insulated rail 84 of sections 74a, "4*" etc., is conductively connected with the rail 79 at one end'and is insulated trom the corresponding track rail of .section 7l by a pin 85. The other track rail 86 of the sections 74E, 74h, etc., is insulated from the crossing rail of standard track by the ' insulations 87 and 88.

When a train going in the direction of the arrow A passes over the crossing 72 it proceeds through the sections 74, 74, etc., and around the standard track sections 7l on the left side of the loop in the ordinary manner. When it runs onto the special three-track insulated sections 74", 74h, etc., it stalls because the running gear is standing on insulated track rails. When the next train proceeds over the crossing in the same direction and runs onto the insulated rail 79-75 the running gear grounds this track and therefore grounds track rail 84 in the three-rail insulated track sections. This permits the power to be applied to the stalled motor and the train proceeds. In the layout here shown the train runs around. the right hand side of the loop and comes onto the special two-rail insulated track so as to start the other train which had been stalled on the three-rail'track.

The layout shown in Figure 6 is similar to that shown in Figures 4 and 5. The insulated rails 75 and 84 corresponding to the rails 75 and 84 of Figure 5 are con nected by a wire 90. Insulating pins are placed at the points marked a and 5 inFigure 5 and the insulation of the V-shaped track element of the crossin is omitted. The Wire 90 may be connecte to the rails by the usual devices 91 and 92 such as are ordinarily provided for connecting wires to toy railroad track.
