Fig. 14 shows the unit of Fig. 12 installed in the tender of Fig. 2 and in the process of being recharged with a supply of fume producing liquid and vshows part of the structure sectioned on plane I4--I4 in Fig. 12.
Fig. 15 shows about twice actual size the compressible relling capsule of Fig. 14 in the sealed form in which it is merchandised before being usedl as in Fig. 14;
Fig. 16 shows a still further modification of the filler inlet and fume outlet incorporated in atoy locomotive wherein the liquid ller inlet projects froml the locomotive like a smoke stack and is made tol emit the smoke-like fumes that are derived from the liquid.
'The toy locomotive and tender of Fig. 1 is shown in 3%; actual size of the so-called H-O gauge toy railroad whose tracks measure inch between rail centers in the two-rail type of track here il-` lustrated. It is therefore apparent that in the interior of such very small toy cars or single units of toy rolling stock, such as the tender I3, very little space isvavailable to contain apparatus capable of successfully producing sound and smoke effects. This stringent space restriction has heretofore necessitated a distribution of the sound and smoke producing apparatus between more than one piece of the toy rolling stock, such as between the locomotive and its tender.
I have devised an organization of the essential components of a sound 'and smoke producing apparatus which enables them, together with an electric power motor by which they are operated, to be contained within as small a space as iesquare inch by 3%" long. This enables them all to be housed within the style and size of tender that is conventional in H-O gauge trains.
'For the 'purpose of constructing the jointly operative sound and smoke apparatus as a subassembly unit that can be built complete as such, and tested in fully operative form before being installed in the car of a toy train, all parts of such unit are mounted preferably on a common base plate I5 which comprises a rigid die casting that may be secured removably to the chassis IB of tender I3 by holding screws I1 in a position accurately determined by downward projecting dowels I8 cast on the baseV plate I5 and tting holes or sockets in the tender chassis. Y Y
. Base plate I5 has cast integrally therewith-an upstanding wall 22 having laterally projecting cast bosses 23 against which is mounted the D- type laminated stator 2.4 of motor I4 carrying the field winding 25. This stator is secured against frame bosses 23 by long holding screws 26 having threaded engagement with the boss 23 and passing through the stator as well as through a bearing plate 23 of insulative material and through tubular spacers 21 holding thelatter n rigid relation to the stator.
Embedded in insulative plate 28 there is a metallic bushing that affords bearing for one end of the motor armature shaft 32 whose opposite end has a bearing 29 in the frame wall 22 and terminates outside'of this frame wall in a worm 33. The motor shaft 32 carries a three-pole armature having respectively three electric windings 35. It also xedly carries the commutator 35 whose radial face is contacted by brushes 31 resiliently .pressed toward said commutator face and fed with electric current by the conductive leaf springs 38 that are mounted in insulated relation on bearing plate 28, there being two brushes 31 on diametrically opposite sides of armature shaft 32.
Thus motor I4 through its shaft worm 33 is constantly in mesh with and able to rotate a worm gear 39 which is pivotally mounted to turn about a vertical axis on the top of a stationary bearing post @Il which post may be cast integrally with base plate I5 or mounted fixedly thereon. Worm gear 39 is retained by a shoulder screw 4I which serves as its pivotal bearing. Worm gear 33 carries a crank pin 12 herein shown as a removable screw stud having threaded engagement therewith. Altogether the foregoing parts constitute a speed reduction gear serving as power transmitting mechanism.
There will next be described the compact organization of a unified sound and fume producer which I have devised in a form susceptible of being contained in the small remaining space measuring square by long. The problem of so doing can not be met merely by making formerly proposed forms of apparatus smaller because to do so would reduce to an unsatisfactory degree the volume of air capable of being pumped for producing the desired smoke and sound effects.
I have combined a resonance box or sound chamber 45, a smoke storing compartment 46 and a liquid containing rellable magazine 41 in an integral hollow casting forming a box-like enclosure separate from base casting I5 and indicated as a whole by the numeral 49. This casting has side walls 55, an end wall 5I comprising external walls, a vertical partition wall 52 and a horizontal partition wall 53. The shape of this casting leaves compartments 45, 46 and 41'only partially housed by walls 5I, 52 and 53. compartments, so far as, casting 49 alone ris concerned, remain open at the bottom or at the top. In assembly, however, the open bottoms of sound chamber "l5 and magazine 41 are leak-proof because closed liquid tight by the mounting of casting d on base plate I5 with an intervening, jointsealing gasket 511. Casting 9 is vheld byfour fastening screws 55 having threaded engagement with internal bosses on walls 5I and '52 andl passing through clearance holes in base' plate I5.
The open tops of sound chamber 45 and compartment are completely sealed liquid tight by a cover plate 56 of insulating material secured against the top of casting 4S by four holding screws 51 having threaded engagement with internal bosses on walls 5I and 52. Y
As best shown in Fig. 4 the side walls 50 of casting 49 are provided with vertically. extending These chamber "45;

The diagram of Fig. 10, in conjunction with the cut-away view of the current collecting structure of one of the toy cartrucks in Fig. 9, makes clear that each truck is equipped with insulative wheels |I that roll on one of the two metallic track rails |02, |04 and with metallicwheels |03 which roll conductively on the other of said track rails. Since the conductive wheels of the two trucks run o nl respectively different track rails,l as is represented in Fig. l10, electric current supplied through either of track rails |02 or |04 is returned to the other of these track rails through a split electricvcircuit containing in one branch the motor I4 and in the other branch the heating coil 84. Current is collected from rail |02 by wheels |03 and passes through the wheel axles |05, brush plate |06,
brush spring |01, and truck pivot stud |08 to the switch |00 and thence divides between motor I4 and heating coil 84 and returns to track rail |04 through the pivot stud |08, brush spring |01, brush plate |06, axles and conductive wheels |03 of the other truck. Thus both the motor'and the heating coil-derive their energizing current from track rails |02, |04.
The detailed construction of switch|00 appears more clearly in Figs. l2 and y13 wherein the casting of 1mi-t base |5'is shown to be hollowed upward at |00 aording cavities that make room for the connection of conductive wiresrespectively to a stationary switch contact ||0 and to the pivot ||2 of a swingable conductive switch contact arm ||3 whose handle end-H4 projects tothe outside of tender|3 sutciently to be manuallyaccessible. The side edges of a notch II5 afford stops in either direction for the swinging movement of switch arm I3. Switch |00-is shown in circuit-making position by full linesiri Fig. l2
wherein the broken lines indicate circuit-break ingposition of this switch. Theztender chassis I0 is topped by the usual removable-casing H6.
secured by screws ||1 and contouredexternally to 'imitate in miniature a load oi coal piled up in the bin vof the tender.
. Fig. 11 shows a modification of the ller fitting 9|.wherein the sealing of liquid in them'agazine or storage compartment 41 is eiected hydraulically by trapping it rather than by means of plugscrew 92 and gasket 03. A nipple ||8 which may be similar to nipple 95,-is sleeved by the. end of a iiexible tube ||9 whoseother end is correspondingly sleeved over the interior end of atubular the storage chamber even when the latter is completely full. It has been mentioned hereinbefore that a cover wall I2 penetrated by inlet |20 might constitute the top wall of a locomotive I2 y as in Fig.Y 16 or some other piece of toy train rolling stock, or-might constitute the roof of a miniature toy building such as a trackside logging mill.
In Figs. 12, 14 and 16 an equivalent for iller inlet I 20 is shownmto consist of an internal boss |29 on -wall 5|of box-castingh49" containinga verticalV intake or fllerrpassage |30.. -In the ena larged'top portion of passage |30 there is inserted a permanent filler funnel I3I which like inlet |20 may be plugged at its internally threaded top end by a removable-thumb screw like |26. Fig. 14 shows the position that funnel I3 I may assume in relation to the top wall |2| of tender casing I6.
Figs. 14 and 15 illustrate an economical, clean and'convenientthrow-away dispensing package in which charges ofY liquid may be merchandised for replenishing magazine 41. |36 is a gelatin capsulelledwith the liquid |38and whose walls are contoured to'form an elongated dispensing nipple |31-which maybe externally threaded to screw into, or may merely be looselyinserted in, ller funnels |3| of Fig.` 174 or |3I of Fig. 16 hereinafter described. In the Vform vmerchandised, the tip endA of the nipple |31A is sealed-by continuity of the gelatin wall of the capsule as shown in Fig. 15. Because of the softness of theA capsule wall the tip end of nipple |31 can be nipped ofi by the thumb nail of a persons hand and the passageway through the spout is so small inv cross section in proportion to its length that the liquid contents of the capsule will not run out even if the open tip of the nipple is turned downward inasmuch as `air cannot enter upward against the weight of the liquid that fillsthe nipple. However the capsule, having ilexible walls, can be squeezed as shown in Fig. 14 as one would squeeze the sides of an oil can and this causes the liquid contents of the capsuleto be discharged into the ller vfunnel .with dispatch and in a clean way which avoids spilling or daubingof any of the oily liquid over external surfaces of the toy. When. the tip of nipple |31 isv externally threaded to screw` into .the internal threads of funnel |3| -or- |3I' with a-liquid tight t before the capsule is squeezed,tliis form of refueling apparatus is absolutely spill proof..
Fig. 16 shows one of many possible structural arrangements whereby'the smoke-like fumes that are discharged from reservoir 46 maybe led preferably laterally into the upper open end portion of a modified nller funnel I3 The flexible conduit 96 from nipple 95 is sleeved over a branch nipple |40 that communicates with the vertical passageway through the modied funnel |3I. Thus this funnel serves the combined function oi. fillerinlet and smoke outlet enabling the liquid magazine 41to be iilled through the smoke stack- 01 of locomotive I2 if the entire puffing unitl is transferred from tender I3 to the hollow interior of locomotive I2 in such position that funnel ISI takes the place of smoke stack 91., -The broken lines |3I in Fig. 16 indicate an upward lengthening of stack ISI which will make it more realistic in imitating the appearance of a power plant smoke stack when projecting above the roof of a toy mill, factory or steam power plant in which myimproved pufiing unit may be installed. Also in the funnel or stack I3I' of Fig. 16, the smaller bottom portion |4| of the passage may be threaded to receive the slender shankedscrew |62 which has a long enough threaded bottom plug` end to cause its top slotted end to protrudeaccessibly from stack|3| when it is sufliciently unscrewed. The presence ofV stopper screw |42 prevents leakage of liquid fuel |38 outfof magazine 41 in case the locomotive vshould overturn but in 'no way interferes with -the discharge of the smoke-like, engine puling fumes out of locomotive stack |3I or |3I.
