Y L c i One object of the inventionis Ato .provide a circuit affecting device of this character adapted to coactwith a traction wheel of the passing a@ toy train. Q v

Another object is to provide a device capable of coacting with a'train wheel throughouty a substantial distance of travel of the latter along the track. L

Another object .is to provide a device of this character which is free from any vliabilityof derailing or` otherwise interfering iwith vthe smooth riding of the train along thetrack;V

A further object is toincorporate theworking parts of such a device in a single unitary appliance capable of being quickly and removably installed as an attachment to the track structure without th'e necessity of lifting the trackage from its iioor or table support surface ,lv and at arbitrary desired locations along the track. f, v

A still further object is to incorporate in such a unit a binding post or binding posts Vsuitable for the ready connection and disconnection of electric lead wires or electric circuit conductors which may be utilized in part for supplying current to, or tapping current from, they rail 0r rails of the toy track. y

The invention further has as its object an 3 embodiment of the aforementioned features in an assembled structure of extreme simplicity and low cost of manufacture. e

These and related objects will appear in greater particular from the following description of a preferred construction illustrative of the nature of the improvements and in which description reference is had to the accompanying drawings,

In Fig. 6 one of the usual sleepersk `III of an 'electric toy krailway Vis shown extending crosspwise under, and supporting, a traction rail I .I jand a power or 'third rail I2. The latterzrail in two-rail forms of toy track construction Amay comprise the other traction rail. Bothrrails are held downwardly against the top of the sleeper as usual by tonguesy I3 struck up out ofthe roof wall-of they hollow sheet metal sleeperln Aa mannerrto overlapthe foot flange I Spofthe lrail andA be squeezed-:downwardly -thereagainst- One or both of the rails may be separated from meeheneel ,21nd, electrical contactewith sleepers I0 by-separatoriacings I4 ofdin'sulativematerial such as thin sheet libre.' Additional tongues like I3 may of course .be employed ,to secure the base flanges I8y to the sleeper at the opposite sideiof each rail butvare omitted frommthe drawing forirclarity. e A All parts of Vmy improved ,contact shoe .appliance comprising a train actuated,H track associated electrical control device, are'mounted on an elongated base'plate I5 whichv may be made of `a strip of thick fibre or otherfsuitably stift'insulat-ive material. Basev plate I5 has a .aperture I6 near each kof its ends shaped. to Vproduce the aperture Ycontained tongueV I.I as .shownin Fig. 7. ff Y 4The. elongated metallic contactshoe 'I9,ha s tiirnedfdown endsZO each-.containing a vertically elongated Vslot 2| occupiedV and vguided by the tongue Il. Normally shoe I9 is'kept'elevated in the position shown in. Figs. 2 and 6 bythe up bearing ends ofthe bowed leaf spring, 22 with the bottom endsof its slots 2l, stoppedby tongues I'I, respectively. The lift` spring (22; is .preferebly mede 0f `goed electric `.conductive illeterielf; .Steh es.. Serine Press. er.: phosphorus bronze, and at its central portion is secured to the upper surface of base plate I by a suitable fastening means such as a hollow rivet or eyelet 23. Eyelet 23 also retains against the bottom surface of base plate I5 a binding post clip 24 of resilient conductive material adapted to trap the end of an electrical conductor or lead wire 25 as shown in Fig. 3. Clip 2'4 is prevented from swiveling about the' eyelet 23 by means of its tongue 25 whi-ch projects upwardly into the material of the base plate. If needed, a similar downwardly by the weight of the locomotive or train unit to its position shown in Figs. 3 and 5 as the wheel rolls along the stretch of track where the shoe is located. Spring 22, of course, is weak enough to yield downwardly to the weight of the locomotive or of any car of the train without lifting it from the rail. Thus the metal of wheel 34 electrically bridges contact shoe I9 and the traction rail II and completes the circuit tongue may extend downwardly from the leaf spring 22 into some loose fitting guiding aper-l Aeyelets3II and held from swiveling about its eye'- let by' a tongue 3I pocketed in the insulatie material of the base plate". The eyelet;33 which secures one of the spring arms 29 may also` be .used to clamp between the latter and base plate I5 the mounting end of a second binding post Vclip 32 which may in all respects be like clip 24 except that it will preferably be shaped lso* that its movement in resiliently flexing to' accommodate the attachment of a separate lead wire 35 willA not interfere with theresilient flexing of the spring arm 29 when the latter is being forced past the rail flange for installing or removing the contact shoe.

Fig. 8 shows that binding post clip 32 may if preferred be independently secured to base plate `I5 by a separate eyelet 33 and thereby removed from such mechanical proximity' to spring arm 29 as might endanger interference inthe respective performances of these two parts'. The clip 32 as here shown remains in electrical contact with spring arm 29 by means of the extended length of its mounting end so that the latter still `remains clamped between spring arm 29 and base plate` I5.

Thus all metallic parts of the contact shoe unit, except only the spring detent arms 28 and 29, are held spaced from electrical contact with rails II, I2, when the base plate I5 is placed between said rails and pressed downwardly against the foot fianges thereof. The entire appliance preferably has a length less than the distance between sleepers I0 in order not to interfere with the latter.

In installing the appliance at any selected location along the track, the mounting arms 28, 29 are forced to cam inwardly to their broken line ypositions in Fig. 6 when passing the relatively narrow space between the foot flanges ofthe rails and thereafter spring apart to their rfull line positions shown in Figs. 5 and 6 so that the base plate I5 brings up against the rail fianges with afsortof snap action and is-yieldingly held there with considerable firmness by the four spring arms v28,- 28 and 29, 29. It will be observed in Fig. 6 that one longedge of contact shoe I9 is thus positioned so closely to the traction rail II that the top surface of this shoe, being normally high enough, is engaged Yby the flange on the metallic conductive wheels 34 of the locomotive or other unit of a toy train and thereby pressed from binding post clip 24 to binding post clip 32, this circuit including eyelet 23, lift spring 22,

icontactshoe I9, wheel 34, track II, and spring f arm 29. The broken line position of contact vshoe I9 in Fig. 3 shows that the shoe is capable of tilting ,freely as well as being free to move up In use, my improved contact shoe appliance in the formi illustrated and described, as well as in forms differing therefrom ln detail, may be set down as a unit between the rails at any selected locatiorrinl a system of toy electric railway track to produce any desired electric circuit controlling effect when the toy train arrives at or passes said location. It will be understood that the electric .circuit affected by the appliance may contain'a.

source' ofv current supply together with electrically operable signal lights, train whistles, bells, or apparatus for starting or stopping the train itself Yby controlling the supply of current to its track or any cycle of track switching or other electrically producible effect in toy railway system apparatus and appurtenances capableV of enhancing the yrealism of the performance of the elements employed in the system.
