53 Claims.

A copending application Serial No. 366,892, now U. S. Patent No. 2,317,974, discloses sound producing apparatus incorporated in electrically powered toy trains or model trains for effectively imitating the puing noise of a steam' locomotive.

The present invention relates to ways and means for producing either in conjunction with such puiiing sounds, or in the absence thereof, the emission of visible fume laden smoke-like vapor from a toy locomotive or other toy structure in realistic pufl's, and in the case of a toy locomotive so that the performance of the vapor shall simulate the familiar puffs of smoke and steam which are discharged by a real locomotive at each stroke of the pistons in their power cylinders and without of necessity being limited to synchronism with the traction wheel speed of my toy locomotive.

An object o! the invention is to produce pulls and wafting billows of visible vapor in miniature form which shall resemble in color and density, and in waiting and dwelling behavior the actual puil's o1' steam and smoke given oir by a real steam engine such as drives a locomotive.

A further object is to augment the effectiveness of the above mentioned imitative pulling sound by the added spectacle of visible smoke pulls given of! preferably in predetermined time relation, and if desired in substantial synchronism, with the occurrence of the pulling sounds.

A further object is to generate and store for thus being ejected from a toy locomotive or other toy structure visible vapor smoke or fumes which shall be entirely harmless to a child playing with the toy, even if he were to breathe such vapors or if they were to come in sustained contact with sensitive tissues of the body. It is also an object to produce realistic visible vapor which shall be harmless to any of the home furnishings with come in contact, and which shall be with respect to all metal and other the track or rolling stock of a toy train is composed.

A further object is to provide apparatus for generating and storing a continuous vsupply of such harmless vapor in suillcient quantity to pronon-corrosive tirely within the unenlarged interior of a conventional toy locomotive or other piece of toy rolling stock hauled thereby, so that neither the presence nor the location of the vvapor generating and storing apparatus shall in any Wayxbe indicated tothe casual observer.

of generating the vapor the material will last for a maximum period before needing replenishment.

A further object is reliably to confine the material from which the vapor is generated against spilling or accidental escape regardless of whether the toy rolling stock by which it is carried is overturned or violently shaken. Another object is to provide for very convenient replenishment of the material whenever required.

A still further object is to generate visible vapor in sufficient volume by the use of heat of such low degree that no temperature other toy structure which can come into contact with the person of a child playing with it.

A further object is to make use of `a. common producing the puffing visible vapor, and to pressure to act through instrumentalities involving uid communication between the sound producing device and the means for generating or storing the vapor.

A still further object mon motivator or the sound producing devices and the vapor electing devices.

Still another object is to make the vapor generating and ejecting apparatus easily applicable moving the apparatus.

The above and other objectives will become more thoroughly apparent from the following description of an illustrative embodiment o f the invention in which description reference is had to the accompanying drawings, wherein:

As in the aforesaid Patent No. 2,317,974, Fig. 1 of this application shows the ordinarily empty hollow space within the enclosing walls or body shell of locomotive tender II to contain a sound producing apparatus which operates to imitate faithfully puing sounds made by the intermittent exhaust of steam and smoke in a real steam 1ocomotive. The structure of the fluid impulsing or fluid activating sound producing apparatus includes a horizontal hollow cylinder 26 one end of which may be completely closed by a cap 21 and the other end of which is open and receives in sliding engagement therewith an impulser or reciprocator here shown in the form of a conventional composite air pump plunger 28 made up of a rigid disc 29 of somewhat smaller diameter than the inside of the cylinder 26 to which disc is secured a cupped washer 30 of very exibie material, such as oil-soaked leather, whose iiexible peripheral flange lls and slidably engages with the interior surface of the cylinder 26 in a manner fully to partition the latter even when disc 29 occupies Positions of oblique inclination to the axis of the cylinder as indicated in Fig. 1. The

inner face of plunger 28 thereby serves as an air impelling instrumentality for generating air ow. Flexible washer 30 is backed up by a stiff plate 3l. Plunger 28 is pulled and pushed back and forth lengthwise of the cylinder by a pitman bar 33 whose bent over end 34 has threaded engagement with screw 35 and is clamped flxedly against backing plate 3l by means of this screw which penetrates and holds together the disc 29. cup

4 washer 36, and backing plate 3i. A lock nut 38 prevents these parts from working loose.

To permit a prime mover in the form of an electric motor, indicated as a whole by 39, to be located at the end of cylinder 26 within the tender il, pitman bar 33 is provided with an offset bend 40. At its end remote from plunger 28 pitman 33 is pivotally connected at 4I to the outer face of a gear 42 which is rotatably supported on frame plate 41 at 48 and thus serves as a crank for reciprocating pitman 33. Gear 42 is constantly in mesh with a small pinion 43. Pinion 43 is fast on one end of the armature shaft 44 of motor 39 which shaft has bearings in bearing plates such as 41 of the motor winch structural details are more fully shown in U. S. Patent No. 2,317,974. The motor is xedly carried on the floor 4B oftender II by means of the aforesaid upright frame plate 41 which may be secured to floor 46 by spot welding, or if preferred in some detachable manner as by removable screws or the like.

An electrical switch I2 carried by tender II is connected to throw motor 39 into or out of circuit with the power rail I6 and traction rails I3, I4 through lead wires 50 and 52. the swingable blade Il of which switch is grounded to the frame of the tender and is thus electrically in circuit with traction rails I3, I4 through the truck 53 and wheels 54 of the tender. A spring stud 55 is fixedly carried in the insulated bar 5B which spans the width of each wheel truck 53 and has its ends fixedly lodged in apertures in the side walls of the wheel truck. As best shown in Fig. 8, the U-shaped current collector shoe 60 has upwardly extending ends whose side edges are notched at 6I to be guided and limited as to vertical movement by forked arms 62 formed on the insulated bar 56 and occupying the notches 6I in the shoe. A coiled spring 63 is conductively anchored to the bottom end of stud and extends to and presses downward against a central struck-up projection in shoe by means of which the bottom end of spring 63 is retained against lateral displacement. The flexible lead wire 52 from motor 39 is soldered to shoe 60.

The use of the current collector shoe 60 on each of the two trucks of the tender insures uninterrupted performance of the vapor puffing effect even though one of these collector shoes might fail to be in contact-with the current supply rail at some position in which the train comes to rest near a turn-out track switch or the like.

Cylinder 26 may be regarded as made up of three end-to-end tubular sections such as pump section 25 forming a pump compartment in which a pump piston such as plunger 28 reciprocates, section 10 forming an air discharge compartment, and section 1I forming the sound compartment. The pump and air discharge compartments are separated by a stationary partition 61 which may be cast integrally with the cylindrical walls or may take the form of a wall of sheet metal or other material thinner than shown in the drawing and peripherally fitting the interior of cylinder 26 so as to make a pneumatically tight `ioint. Partition 61 contains a small central orifice 68 at which a stream of air may be generated and projected toward the left in Figs. 1 and 6 when plunger 28 moves in that direction. The air discharge compartment and sound compartment are separated by a stationary partition 69 winch is preferably rigid throughout and may take the form oi' a dished cup of sheet metal or the like whose peripheral flange ts and forms an air tight joint with the interior surface of cylinder 2E.

l 68 may be .076"

Partition 99 is provided with means for iluctuating air flow in the form of an elongated aperture 12 which is both wider and longer than orifice 58, and whose ends are bordered by oppositely inclined lips 66 and 96 of eyelid shape formed by warping, in respectively opposite directions from' the plane of the partition. -the otherwise flat sheet material of which partition 69 is composed, as is more clearly set forth in the aforesaid Patent No. 2,317,974.

In the last said patent it is set forth that orifice in diameter, circular hole 16 may be in diameter and aperture 12 may be :1'1" wide by long, where the diameter of the sound chamber isl" and the spacing from partition 61 to partition 69 is H; and that the foregoing are merely suggestive dimensions which may be varied proportionally or in degree. They in no way limit the scope oi' the appended claims. Gear 42 may have sixty-four teeth and pinion 42 may have ten teeth whereupon if the gear turns 80 to 120 R. P. M. the pinion would rotate six times as fast, these also being but illustrative specifications.

Whereas partition 69. having a lipped aperture as described, is adequate to sounds it is desired to produce can be enhanced by the addition of other means for fluctuating airflow in the form of an auxiliary stationary baille plate 15 containing a simple centrally disposed circular hole 16 spaced from aperture 12 toward partition 69, mounting tabs .such as 14 are pro-` vided having suitable differing axial length which may be secured to partition 69 by soldering, welding or in a removable manner if preferred. A cutout 13 in the wall of plays a further important p'art in the pneumatic performance of the fume puffing apparatus next to bevdescrlbed.

The present improvements involve in particular the addition oi smoke-like visible vapor generating storing and ejecting apparatus to the means presence nor the location of the vapor generating and pulling apparatus shall be obvious to a casual observer of the toy tion on its track.

In keeping with these objectives, the smoke-like vapor generating and storing unit or fume reserthese improvements, which is indicated as train while in natural posithe locomotive traction motor 22.

For replenishing the oil in chamber 96 filler plug screw 99 may be removed. washer |00 clamped under the head of screw 99 prevents leakage of oil. Completely filling chamber 96 with oil through the opening plugged by screw 99 requires turning the locomotive up on end. However, an alternatively usable filler plug screw 99 whose head clamps the gasket washer tender il.

Smoke chamber 96 comprises a reservoir of agences hooded nature shaped to store therewithin and to hinder the escape in unwanted directions therefrom of residual smoke or fumes derived from the heating of oil in wick 89 and has a rearwardly directed nipple I| and a forwardly directed nipple |02. The cylindrical wall of sound compartment 1| may carry a similar nipple at |03. A length of flexible tubing |04 of rubber or other suitable conduit material connects with and extends from nipple |03 to nipple |0| thus giving fluid .communication between sound compartment '|I and smoke chamber 85 and forming part of a passageway giving pneumatic communication between reservoir 85 and certain fume incitng or impulsing apparatus including the impulser or reciprocator 2B hereinbefore described. Flexible tubing |04 permits freedom of locomotive I0 and tender l| to swerve relative to each other when the'locomotive is hauling the tender by means of pivotal coupling 51 around curves in the track. Another length of ilexible tubing connects with and extends from nipple |02 to a vapor outlet at which the tube gives freely to the exterior of the locomotive through the limitative smoke stack |06. The combined tubing helps form a course of conduit which includes the fume chamber or reservoir 85. As an example of workable dimensions which have been found satisfactory in practicing the invention, where the smoke chamber measures approximately 1" x "A" x l/2", the orifice in nipple |03 may be in diameter and the orifices in nipples |0I and |02 may respectively be Jg" and in diameter. The inside diameter of tubes |06 and |00 may be 5/8".

. In Figs. 6 and 7 an extra and separate pump or second iluid impulser indicated as a whole by ||0 is provided additional to the cylinder 29 of the sound apparatus which cylinder in this modiiied form of tender may remain in all respects as shown in the aforesaid Patent 2,317,974. Pump I I0 comprises a cup-like structure or pump casing interposed between motor 39 and the cylinder 28 its open end facing the open end of the latter. A pump plunger |I2 similar to the pump plunger 20' is composed of a dished core IIS, a backing plate III, and sandwiched therebetween a cupped flexible piston ||5 of leather or other suitable substance saturated or coated with grease or the like to enable its turned-over peripheral edge to engage slidingly with the inner cylindrical surface of pump casing ||1 in a vmanner to force air toward the right in Figs. 6 and 7. As usual in air pump operation, this peripheral edge collapses radially inward to permit plunger ||2 to slide toward the left in said iigures without creating appreciable suction between the plunger and the right end of the pump casing. The inner face of plunger I|2 thereby serves as a fluid impelling instrumentality for generating air flow. Core H3, plate ||4 and ilexible piston ||5 are clamped ilxedly together on one riveted-over end of a rigid piston rod IIB of reduced diameter and the opposite end of piston rod ||6 is also reduced in diameter and penetrates and is riveted over against the dished core 29 thus clamping `ilxedly together said core 29, piston 30 and backing plate 3| of the pump plunger 20'. Also and by the same means there is xedly clamped against backing plate 3|, the turned-over end 34 of a lengthwise reciprocative bar 33' having oiset 40 and whose opposite end pivotally engages an outwardly projecting stud ||8 iixedly carried bycross head ||1, the latter constituting a rectangular block freely slidable, coniined and guided in the channel bracket |00 which is of C-shaped cross section and welded or otherwise secured iixedly against the outside of pump casing as shown in Fig. 13. The pitman link |08 is pivotally coupled to the cross head stud ||8 and also to gear 42 at 4| thus enabling rotation of this gear to reciprocate cross head stud I I8 horizontally of the channel bracket and thereby reciprocate both plungers 28' and ||2 in unison as a single reciprocator having oppositely directed vapor pumping faces in their respective pump casings 28 and III. In the construction of Figs. 6 and 7 it will be appreciated that neither of the pump plungers 28 nor ||2 are required to incline away from perpendicular relation to the axis oi' their cylindrical casings as they reciprocate therewithin.

Pump casing III is equipped with a nipple H9 similar to nipple |02 of Fig. 4 and a length of flexible tubing |04' fits over this nipple and ex tends to nipple |0| of container 82 as does tubing |04 in Fig, l. Either tubing Ill or |06' may easily be detached from nipple |0| when it is desired to separate the tender from the locomotive. 1f desired the stack also may be equipped with an internal nipple, as |20 in Fig. 1l, for the convenient gas tight attachment of tubing |05. In some cases this nipple may be of the L-branch type, one of whose branches will receive the supplementary tubing |'2I which leads to the location of the imitative locomotive cylinder I9. As shown in Fig. l2, this cylinder may incorporate directly beside the locomotive piston rod 2li a rearwardly directed small orice |22 for vapor arriving through tubing |2I, the latter connecting to a nipple |23. In order to eilect more even distribution between stack |06 and cylinder I9 of the steam-like vapor which is blown out of the generator 80, tubing |2i may, if desired, branch oi from tubing |05 by means of some Y-branch connector as at 52d, instead of at the L-branch nipple |26. In that case the latter could be plugged. Or if the L-branch nipple were used the Y-branch connector could be plugged. Or when vapor is to be delivered only to the stack of the locomotive, both nipple E20 Vand connector |25 may be plugged or omitted from the construction.

The operation will be described with reference to the diagram of circuit connections in Fig 10. In both Figs. 9 and 10, a toy transformer |29 of the voltage modulating type is equipped with a voltage varying control handle |3| which can be swung away from an extreme position that will cut out .all current supply to power rail I6, and through a. range of other positions wherein various voltages, up to say 15 volts, will be impressed on the track circuit. Transformer |29 by means of an attachment cord |32 is adapted to be tapped into any ordinary householdl electric outlet delivering the usual volts through mains |33. At quite low voltages Within the indicated range of variable voltage under 15 volts the motor 39 on the tender or as energized through circuit |66052M50 |2-I3 will run at low speed for producing pumng effects if switch I2 is closed. Simultaneously the locomotive traction motor 22 will be energized through the A or C positions of reversing switch 23 which alternate with positions B and D as the commutator drum of this switch is advanced step by step by successive strokes of the plunger of solenoid |30 at each cut-oil and restoration of current supply to power rail I6 through regulating transformer |29. In these improvements mote control and quite independently of the motion or speed of running of locomotive I or its traction motor 22. These puffing effects may consist of pulling sounds emitted from an invisible source within tender H which sounds therefore seem to the observer to come from the locomotive. itself, and such effects in the present imance.

The vapor is generated according to this invention by heating resistance wire 90 to a tem perature less than red hot through current `in electric circuit |6-l 1-96-95-94-90-93- l 3. This in no way impairs nor burns nor tends to At each reciprocative excursion of plunger in Fis. 1, or of plungers 28' 7, a fricative sound such exhausted steam and smoke in a real locomotive is produced by the play of a jet of air from orifice 68 upon the lips of partition apertures 18 or 12, and in correspondence with `such sound a puff or billow of visible smoker-like vapor is blown out of the vapor generator 8l 28 and H2 in Figs. 6 and and thus produces the appearance of a pun' of smokelike vapor leaving locomotive stack rearwardly spurted out in the close neighborhood of the engine piston rod 24 as a momentary .iet of vapor of steam-like appearance which realistically imitates steam that commonly escapes from the packing about the piston rod in a real locomotive.

22 may remain stalled even i as is made by abruptly intermittently by means the ability oi the return Fig. 1 to create a suction in tube I that is capable of drawing smoke or fumes from container 82 backward through this tube.

Thus, .whereas cylinder 26 is' but illustrative of any sort of vapor constrainingpassageway that might be provided to afford pneumatic communication between the impulser or reciprocator 28 and fume reservoir 85 for directing toward pules derived from working cator 28, the cut out 13 in compartment 10 constitutes a bleeder opening in such passageway in branch relation thereto in the neigh- In the above described manner it will be appreelated that the occurrence of the puffs of visible vapor are synchronized with the occurrence of the puffing sounds as is characteristic of these and steam as elected under forced draft when a heavy train is beginning to pick up speed, is

oil of menthol, camphor oil, many kinds and derivativesof crude or petroleum oil, etc. It is desirable to select oils which do not vaporize so fast as to require impractically frequent replenishment while the oils should be light enough to readily seep through the wicking 90 by capillary attraction.

The vapor, fumes, or smoke generated in the way and by means of the thermal Vaporizing apparatus herein specified will in no way be harmful to person or property however long and intimate the contact with such fumes may be. The visible vapors thus puffed out of the toy locomotive stack intermittently will in miniature volume wait and disperse in close similarity to the behaviour of mixed smoke and steam as ejected from the locomotive of a real steam train, trailing out and hanging low over the train and track after the locomotive has passed. The heat generated in the electrothermal vaporizer never makes any of the surrounding parts of the toy hot enough to burn the hand. The insulative cover plate 83 serves also as a heat insulator to prevent escape of heat from coil 90vto container 82.

While the invention may be embodied in any vapor puffing toy where realistic sight and sound effects are desired and whereas various definite specifications have been given herein as a guide to practical embodiment of the invention it will be understood that many and in some cases wide departures may be made from such specifications within the intended scope of the following claims whose terms are inclusive of all substitutes and equivalents for the particular forms, sizes and arrangements of the parts herein disclosed that are commonly known or likely to be suggested by the disclosure hereof.
