AARON H. GILL, OF WEST HAVEN, CONNECTICUT, ASSIGNOR PORATION, A CORPORATION OF NEW YORK TO THE LIONEL COR- TOY RAILROAD TRACK SWITCH.

Application led July 11,

- To all whom t m my concern e vide in an electrical toy railroad outfit a track switch which m'ay be mechanically or electro-magnetically Operated for switching the toy train from one track to another, and which shall be simple in construction, cheap to manufacture and adapted to be easily manipulated.

Other objects of this invention [will in part be obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combination of elements and arrangement of parts which will be ,exemplified in the construction hereinafter described and of which the scope of applicationI will be indicated in the following claims.

In the accompanying drawings, in which is shown one of various possible illustrative embodiments of this invention,

f Fig. l is a plan View showing a toy switch -embodying this invention as applied to a toy electrical railroadhaving a main line and vbranch lines, the electrical connections for electro-magnetically operating the switch being shown diagrammatically;

Fig. 2x is a cross-sectional View taken throughFthe switch mechanism along line Fig` 3 is a cross-sectional view cut along line 3-3 of Fig. 1;

Fi 4 is a cross-sectional View in plan of the e ectrical switch box, taken along line 4-4 of Fig. 5; and

Fig. 5 is an end cross-sectional View of said switch box.

Referring in detail to the drawing, 10 indicates the main railroad track of a toy electrical railroad, and 15 the branch line thereof. The track 10 comprises the

rails

11, 11 extending over cross-ties 12 and an intermediate third rail -13 insulated as at 14 from said tics. Preferably, the rails and cross-ties are made in one piece from sheet metal, the cross ties being in the form of bases or stand- 1922. Serial No. 574,214.

ards depending downwardly from the rails and serving as supports whereby the railroad rests on the Hoor of the room or any other suitable support. The branch line 15 comprlses

similar rails

16, 16 extendin across similarly constructed cross-ties 17 and an intermediate third rail18 insulated from the cross-ties as at 19.

Where the branch line 15 connects with the main track 10, the respective

third rails

18, 13 thereof are connected by a fork member20` from which extends a widened portion 20a, so that the contact shoe (not shown) of the toy car may stay in contact with the third rail as the toy train switches from one track to the other.

Thevusual switch tongues

21, 22 are provided which maybe moved into proper switching the'train rom the main track to the branch track and vice versa. The

switch tongues

21, 22 are connected at their ends by

cross-braces

23, 28. The cross-brace 23 1s pivoted as at 24 to the rail tie 25 so that the tongues 21,-22 may be operated asa unit and switched into deslred position as hereinafter described.

The track switch comprises a switch arm 26 secured at one end as at 27 by any suitable means, such as rivets, to the under side of the cross-brace 28. The free end 26a of the switch arm is loosely pivotally connected to a link 29, the latter having a slot 29 formed therein to permit a little play at the pivoted end which is eccentrically connected as at 29a to a rotatable disc 30. Extending from the latter is an operating handle 31 formed preferably integral therewith. s The disc 30 1s disposed at the base of the signal standard 32 and is connected to or formed integral with a vertical shaft 33 housed in said standard. In this way, a signal tower (not shown) mounted on said shaft may be operated simultaneously with the operation of the switch.

The automatic electro-magnetic means for operating the track switch at a distance from the tracks will now be described. Disposrd oppositel the

members

26, 29, of the switch mechanism are two electro-

magnets

37, 38, arranged to either side of the pivoted end of the lever 29 with their

cores

39, 40 in opposed relation to each other. A common armature 41 is provided for the electro-magnets, said armature 41 being secured to the horizontal member 26 adjacent the ond 26a position as desired for thereto.

thereof. A switch boX 42 is adapted to control the supply of current to the

electromagnets

37, 38 so that the circult may be closed throu h one or the other of the

magnets

37, 38. Vhen electro-magnet 37 is energized, the armature 41 is attracted to the core 39 carrying with it the member 26. and thus moving the

tongues

21, 22 into position for the branch track as shown in dotted lines in Fig. 1 for the train. Similarly when the-electro-magnet 38 is energized the armature 41 is drawn towards the core 40 and the switch is set for the main line as shown 1n full lines in said figure. It will be understood of course that where several branch lines or sidings are used, a similar track switch mechanism will be provided at each' junction and pairs of electro-magnets 37', 38 similarly installed and connected to the switch box.

The current for the electro-magnetsis controlled by the electric switches 43 disposed in the switch box 42. The latter comprises a casing 44 preferably rectangular 1n sha pe and a flat cover 45 detachably secured Steur-ed to the interior face 45a of the cover by any suitable means 'such as nails, is a plurality of narrow channel shaped members 46 substantially of the cross-section shown in Fig. 5 having the upper portion 46a of the vertical channel 'face 46b cut away as at 46. Each of these cutaway faces 46c are provided with

contacts

47, 47 for the purpose hereinafter pointed out. The material 46c of the horzontal portions of the channel members 46 is recessed on one of the sides thereof as at 48 in which recess are pivotally held the switch levers or handle members 49, extending through slots 50 in the cover 45. Each of the handle members 49 is provided with a metallic contact piece 51 adapted to makecontact with the

contacts

47 or 47 depending on the position in which the lever is thrown. Each of the faces 46b is provided with a resilient cushion 52 of rubber or other suitable resilient material so that when a given lever 49 is thrown in position to make contact 47 or '47, the cushion 52 acts to restore the lever and quickly break the contact. In this way the circuit through the electro-

magnet

37 or 38 is completed only for a. short interval long enough to operate the armature 41 and then the. circuit again broken. On the outer faces 451 of the cover are two series of bind`

ing posts

53, 54, nrespectively in the circuits of the electro-magnets 38, 38', etc. for setting the track switches in the main track positions and the

electromagnets

37, 37 etc. for the branch track positions. The current is lcd into the switch box from the third rail, or an independent source through the binding post by means of lead wire 56. The contacts 51 on the switch handles are connectcd in parallel across the supply line, the cura child may rent being led by means of a lead wire 57 to each of the binding posts 5la and thence by branch wires 58 to the respective contacts 51. The binding posts 53 are each connected by means of branch wires 59 to their respective contacts 47, and the binding posts 54 are likewise each connected to the respective contarts/47 by means of branch wire-s 60. A

lead'wire

61, 61 further connects each binding post 54 to its

corresponding electromagnet

38, 38 and thence to ground as shown at G. Similarly a

lead wire

62, 62 connects each binding post 53 to its corresponding electro-

magnet

37, 37 and thence to ground.

The circ-uit through a particular set of magnets say 37 38 can now be easily traced.

On throwing the lever against thecontact 47a the current passes out through lead wire 62 to electro-magnet 38 and then to ground thus completing the circuit. When the switch lever 49a is thrown in the oppo-I site direction. against contact 47, the current passes by lead wire 61 to electromagnet 37 and thence to ground. It will be clear that eac-h of the switch levers 49 controls in this way a separate set of electro-magnets such as 37, 38, 37 38 etc. and that the switch box thus becomes the control device for the entire track layout. Each switch lever may be marked to indicate vthe portion of the main track and branch track controlled thereby and thus at a'distance from the tracks run the train as desired.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved and which is well adapted to meet the conditions of practical use.

As various possible -embodiments might be made of the above invention and as variouschange's might be made in theembodiment above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.
