`
`Application August 30, 1941, Serial No. 409,056
`53 Claims.
`(Cl. 46-113)
`
`1
`A copending application Serial No. 366,892, new
`U. 8. Patent No. 2,317,974, discloses sound pro-
`ducing apparatus incorporated in electrically pow-
`ered toy trains or model trains for effectively
`imitating the puiflng noise of a steam‘ locomotive.
`The present
`invention relates to ways and
`means for producing either in conjunction with
`such pumng 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 pufls, and in the case of a. toy locomotive
`so that the performance of the vapor shall simu-
`late the familiar puffs of smoke and steam which
`each stroke “
`are discharged by a real locomotive at
`of the pistons in their power cylinders and with-
`
`5 of generating the vapor the material will last for
`
`l0
`
`\
`15
`
`A still further object is to generate visible Vapor
`
`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 puffs given
`01! preferably in predetermined time relation, and
`if desired in substantial synchronism, with the
`occurrence of the pufllng 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
`‘ which it may come in contact, and which shall be
`
`or harming children can be built up in any of the
`the toy rolling stock, locomotive or
`other toy structure which can come into contact
`with it.

`
`ties involving fluid communication between the
`sound producing device and the means for gen-
`erating or storing the vapor.
`A still further object is to make use of a com-
`40 mon motivator or a common prime mover sepa-
`rate from the tractional motor of the toy’ locomo-
`tive for operating the sound producing devices
`and the vapor ejecting devices.

`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 H to contain a sound
`producing apparatus which operates to imitate
`faithfully pufllng sounds made by the intermittent
`exhaust or steam and smoke in a real steam lo-
`comotive. The structure of the fluid impulsing
`or fluid activating sound producing apparatus in-
`cludes 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 re-
`clprocator here shown in the form of a conven-
`tional 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 flexible ma-
`terial, such as oil-soaked leather, whose flexible
`peripheral flange fills and slidably engages with
`the interior surface of the cylinder 28 in a man-
`ner fully to partition the latter even when disc
`29 occupies p°5itions 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 flow.
`Flexible washer 30 is backed up by a stiff plate
`3|. 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 engage-
`ment with screw 35 and is clamped fixedly against
`backing plate 3| by means of this screw which
`penetrates and holds together the disc 29, cup
`
`4
`washer 38, and backing plate Bi. A look 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 38, to be
`located at the end of cylinder 26 within the tender
`ii, pitman bar 33 is provided with an offset bend
`40. At its end remote from plunger 28 pitman
`33 is pivotally connected at II 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 re-
`ciprocating 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 which structural details are
`more fully shown in U. S. Patent No. 2,317,974.
`The motor is fixedlycarried on thefloor48 of tender
`H by means of the aforesaid upright frame plate
`47 which may be secured to floor 46 by spot weld-
`ing, 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 cir-
`cuit with the power rail is and traction rails I3,
`I4 through lead wires 50 and 52, the swingable
`blade ll of which switch is grounded to the frame
`of the tender and 3 thus electrically in circuit
`with traction rails I3, I4 through the truck 53 and
`wheels 54 of the tender. A spring stud 55 is fixed-
`ly carried in the insulated bar 55 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
`6| to be guided and limited as to vertical move-
`ment by forked arms 62 formed on the insulated
`bar 56 and occupying the notches 61 in the shoe.
`A coiled spring 53 is conductively anchored to the
`bottom end of stud 55 and extends to and presses
`downward against a central struck-up projection
`in shoe 60 by means of which the bottom end of
`spring 63 is retained against lateral displacement.
`The flexible lead wire 62 from motor 39 is soldered
`to shoe 60.
`The use of the current collector shoe to on each
`of the two trucks of the tender insures uninter-
`rupted performance of the vapor pufilng 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 ‘ll 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 joint. Partition
`61 contains a small central orifice 88 at which a
`stream of air may be generated and projected to-
`ward the left in Figs. 1 and 6 when plunger 28
`moves in that direction. The air discharge com-
`partment and sound compartment are separated
`by a stationary partition 69 which is preferably
`rigid throughout and may take the form of a
`dished cup of sheet metal or the like whose pe-
`ripheral fiange fits and forms an air tight joint
`with the interior surface of cylinder 26.

`hooded nature shaped to store therewithin and to
`hinder the escape in unwanted directions there-
`from of residual smoke or fumes derived from
`the heating of oil in wick B9 and has a. rearwardly
`directed nipple IOI and a forwardly directed nip-
`ple I02. The cylindrical wall of sound compart-
`ment ‘II may carry a similar nipple at I03. A
`length of flexible tubing III4 of rubber or other
`suitable conduit material connects with and ex-
`tends from nipple I03 to nipple IOI thus giving
`fluid communication between sound compart-
`ment 'II and smoke chamber 85 and forming part
`of a passageway giving pneumatic communica-
`tion between reservoir 85 and certain fume incit-
`.ing or impulsing apparatus including the impulser
`or reciprocator 28 hereinbefore described. Flex-
`ible tubing I04 permits freedom of locomotive I0
`and tender II to swerve relative to each other
`when thelocomotive is hauling the tender by
`means of pivotal coupling 51 around curves in the
`track. Another length of flexible tubing I05 con-
`nects with and extends from nipple I02 to a vapor
`outlet at which the tube gives freely to the ex-
`terior of the locomotive through the limitative
`smoke stack I06.
`"I‘he combined tubing helps
`form a course of conduit which includes the fume
`chamber or reservoir 85. As an example of work-
`able dimensions which have been found satisfac-
`tory in practicing the invention, where the smoke
`chamber measures approximately 1" x 3/4_" x %",
`the orifice in nipple I03 may be 3%” in diameter
`and the orifices in nipples lol and I02 may re-
`spectively be 9;" and 1*." in diameter. The inside
`diameter of tubes I06 and III! may be 54;".
`In Figs. 6 and '7 an extra and separate pump
`or second fluid impulser indicated as a whole by
`H0 is provided additional to the cylinder 28 of
`the sound apparatus which cylinder in this modi-
`fled form of tender II’ may remain in all re-
`spects as shown in the aforesaid Patent 2,317,974.
`Pump I III comprises a cup-like structure or pump
`casing III interposed between motor 39 and the
`cylinder 28 its open end facing the open end of
`the latter. A pump plunger II2 similar to the
`pump plunger 29’ is composed of a dished core
`III, a backing plate Ill, and sandwiched there-
`between a cupped flexible piston H5 or leather
`or other suitable substance saturated or coated
`with grease or the like to enable its tumed-over
`peripheral edge to engage slidingly with the in-
`ner cylindrical surface of pump casing H1 in a
`‘manner to force air toward the right in Figs.
`6 and 7. As usual in air pump operation, this
`peripheral edge collapses radially inward to per-
`mit plunger II2 to slide toward the left in said
`figures without creating appreciable suction be-
`tween the plunger and the right end of the
`-«pump casing. The inner face of plunger
`II2
`thereby serves as a fluid impelling instrumental-
`ity for generating air flow. Core II3, plate III
`and flexible piston II5 are clamped fixedly to-
`gether on one riveted-over end of a rigid piston
`rod IIII of reduced diameter and the opposite
`end of piston rod H6 is also reduced in diameter
`and penetrates and is riveted over against the
`dished core 29 thus clamping fixedly together
`said core 29, piston 30 and backing plate 3| of
`the pump plunger 28'. Also and by the same
`means there is fixedly clamped against backing
`plate 3|, the turned-over end 34 of a lengthwise
`reciprocative bar 33’ having offset to and whose
`opposite end pivotally engages an outwardly
`’ projecting stud II8 fixedly carried by.cross head
`III, the latter constituting a rectangular block
`freely slidable, confined and guided in the chan-
`
`8
`I09 which is of C-shaped cross sec-
`nel bracket
`tion and welded or otherwise secured fixedly
`against the outside of pump casing III as shown
`in Fig. 13. The pitman link I08 is pivotally
`coupled to the cross head stud H8 and also to
`gear 42 at El 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 H2 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 II2 are required to incline away
`from perpendicular relation to the axis of their
`cylindrical casings as they reciprocate there-
`within.
`Pump casing III is equipped with a nipple II9
`similar to nipple I02 of Fig. 4 and a length or
`flexible tubing I94’ fits over this nipple and ex-
`tends to nipple Ilil of container 82 as does tub-
`ing I04 in Fig, 1. Either tubing I03 or I05’ may
`easily be detached from nipple IIII when it is
`desired to separate the tender from the loco-
`motive.
`If desired the stack also may be
`equipped with an internal nipple, as I29 in Fig.
`11, for the convenient gas tight attachment of
`tubing I05.
`In some cases this nipple may be
`of the L-branch type, one of whose branches
`will receive the supplementary tubing I'2l which
`leads to the location oi‘ the imitative locomotive
`cylinder I9. As shown in Fig. 12, this cylinder
`may incorporate directly beside the locomotive
`piston rod 26 a rearwardly directed small orifice
`I22 for vapor arriving through tubing Hi, the
`latter connecting to a nipple I23.
`In order to
`effect more even distribution between stack I06
`and cylinder I9 of the steam-like vapor which
`is blown out of the generator til, tubing I25 may,
`if desired, branch oil from tubing I05 by means
`of some Y-branch connector as at
`I25, instead
`of at the L-branch nipple I26.
`In that case the
`latter could be plugged. Or if the L-branch mp-
`ple 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 I20
`, and connector I25 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 I29
`of the voltage modulating type is equipped with
`a voltage varying control handle I3I 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 im-
`pressed on the track circuit.
`Transformer I29
`by means of an attachment cord I32 is adapted
`to be tapped into any ordinary household electric
`outlet delivering the usual 125 volts through
`mains I33. At quite low voltages within the in-
`dicated range of variable voltage under 15 volts
`the motor 39 on the tender II or II’ as en-
`ergized through circuit
`I6——60—52—-M—5lJ—
`I2—I 3 will run at low speed for producing pulling
`eflects 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 I30 at each cut-oif and restoration
`of current supply to power rail I6 through regu-
`lating transformer I29.

`At each reciprocative excursion of plunger 28
`in Fig. 1, or of plungers 28' and II! in Figs. 6 and
`7, a fricative sound such
`as is made by abruptly ‘
`exhausted steam and smoke in a real locomotive

`is produced by the play of a Jet of air from ori-
`fice 60 upon the lips of partition apertures 10 or
`12,
`
`piston 28 or II 2 in working or return conditions
`and transmitted from compartment 1| through
`tubing I04. This fluid inciting or activating
`effect of piston 20 or
`II2 causes vapor
`to
`leave

`produces the appearance of a puff of smoke-

`of vapor of steam-like appearance which realis-

`from the packing about the piston rod in a real
`locomotive.

`It is
`desirable to select oils which do not vaporize so
`fast as to require impractically frequent replen-
`ishment while the oils should be light enough
`to readily seep through the wicking 90 by capil-
`lary 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 waft 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 to}!
`hot enough to burn the hand. The insulative
`cover plate 83 serves also as a heat insulator to
`prevent escape of heat from coil 9ll.to 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 substi-
`tutes and equivalents for the particular forms,
`sizes and arrangements of the parts herein dis-
`closed that are commonly known or likely to
`be suggested by the disclosure hereof.
`I claim:
`1. In a hollow toy having a vapor outlet for
`the emission of fumes from said toy, a replenish-
`able substance convertible by heat into fume-
`laden vapor, means to generate said heat, means
`for storing said fume-laden vapor simultaneously
`with the generation thereof, and means to liber-
`ate at least portions of the stored vapor from said
`toy at particular times through said outlet.
`2. In a combined sight and sound effect toy,
`the combination of, a toy structure having a dis-
`charge outlet for pseudo engine exhaust, a pro-
`ducer of pneumatic pulling sounds including a
`fluid impulser, a reservoir supplied with smoke-
`like fumes, and apparatus in said toy structure
`for causing fumes derived from said reservoir to
`depart from said discharge outlet including a
`course of conduit constructed and connected to
`lead fluid from said impulser to said reservoir
`and also to lead fumes from said reservoir to said
`outlet.
`3. A hollow toy including in combination, a
`vapor outlet for the emission of fumes from the
`toy, a repository in said toy receptive to a replen-
`ishable substance convertible by heat into po-
`tentially visible fumes, means to heat said sub-
`stance sufllciently to convert the same progres-
`sively into said fumes, a hooded reservoir for
`storing residual fumes -derived from said sub-
`stance during heating of the latter having vapor
`communication with said outlet and shaped to
`hinder escape of said residual fumes from said
`reservoir whereby said residual fumes are re-
`tained by and caused to dwell within said reser-
`voir, fume inciting apparatus including an im-
`pulser, a passageway affording pneumatic com-
`munication between said apparatus and said res-
`
`12
`ervoir in a manner to transmit to residual fumes
`in said reservoir successive pressure forces de-
`rived from said impulser thereby to crowd out of
`said reservoir and through said outlet at least
`portions of said residual fumes in intermittent
`puffs.
`4. In a combined sight and sound eflect appa-
`ratus for toys, a producer of pulling sounds in-
`cluding a. fluid activating device, a vapor retain-
`ing reservoir containing vapor having an appear-
`ance simulating smoke and/or steam when lib-
`erated into free air, and apparatus for causing
`the vapor in said reservoirto be incited in a
`manner to leave the toy in visible smoke-like or
`steam-like puffs, said apparatus including a pas-
`sageway arranged to afford fluid communication
`between said device and said reservoir thereby
`to cause vapor in said reservoir to be incited and
`liberated from the latter, together with means
`operatively associated with said passageway con-
`structed and arranged to prevent withdrawal of
`fluid from said reservoir through said passageway
`by said device.
`5. In a hollow toy having a vapor outlet for
`the emission of fumes from said toy, a repository
`in said toy receptive to a replenlshable substance
`convertible by heat into potentially visible fumes,
`means to generate said heat. a reservoir hooded
`to suilicient extent to store therewithin residual
`fumes derived from said substance simultaneous-
`ly with the generation of said heat, and fume
`inciting apparatus including an impulser pneu-
`matically communicating with said reservoir in
`a manner to exert intermittent pressure but not
`appreciable suction upon residual fumes therein.
`thereby to crowd out of said reservoir and through
`' said outlet in a course foreign to said apparatus
`at least portions of said residual fumes in inter.
`mittent visible puffs.
`6. A hollow toy including in combination a va-
`por outlet for the emission of fumes from the
`toy. a repository in said toy receptive to a re-
`plenishable substance convertible by heat into
`potentially visible rumes, means to heat said sub-
`stance sufflciently to convert the same progres-
`sively into said fumes, a. reservoir of hooded na-
`ture for storing residual fumes derived from said
`substance during heating of the latter having
`vapor communication with said outlet and shaped
`to hinder escape of said residual fumes from said
`reservoir in unwanted directions whereby said re-
`sidual fumes are retained by and caused to tarry
`within said reservoir. fume inciting apparatus in-
`cluding a reciprocator adapted to perform alter-
`nate working and return motions, a passageway
`affording pneumatic communication between said
`apparatus and said reservoir in a manner to di-
`rect toward residual fumes in said reservoir suc-
`cessive pressure impulses derived from working
`motion of said reciprocate: thereby to crowd out
`of said reservoir and through said outlet at least
`portions of said residual fumes in intermittent
`puffs, together with a bleeder opening disposed
`in branch relation to said passageway permitting
`vagrant vapors to flow therethrough toward and
`away from said reciprocator in a manner to di-
`lute pneumatically the forcefulness with which
`, said motions of the reciprocator act upon the re-
`siduai fumes insaid reservoir.
`7. A hollow toy as defined in claim 6, in which
`the said bleeder opening ‘is sumciently large and
`sufficiently near the said reciprocator to prevent
`exertion of appreciable suction on the said resid-
`ual fumes in the said reservoir by the said re-
`turn motion of said reciprocator.
