9Ciairns. (Si. 4ti-9) ing wire spiral) extends to the top extremity of the capillary tube.

The heating wire spiral is rolled up onto a heat-resistant small tube of current-insulatingnraterial, wherein the capillary tube is slidably supported. Instead of this arrangement the heat producer (heating wire spiral) may also be directly spiralled onto the capillary,

Preferably part of the housing of the device ofthis invention forms at the same time pant of the funnel of the toy. In anialternate embodiment the housing may be put into the funnel of the toy-locomotive. In the latter instant,-it is convenient if according to the invention the housing by means of a flange arranged at its extremity supports itself and centers on the funnel part of the toy so that a heat insulating collar space of air is formed between the housing of the device. of this invention and the funnel part of the toy-locomotive. Finally, in still another embodiment of the invention the heating wire spiral is bedded into a casing of current insulating material and the two filament current wire connectionsof theheating wire spiral carry the sleeve and the heating wire spiral. The lower filament current connection which read in. connection with the accompanying drawings in .which:

FIG. 1 shows in side-view a device of this invention built into the front part of a toy-locomotive;

FIG. 2 is a longitudinal sectional view of the device of FIG. 1;'

FIGS. 3 to 5 are three longitudinal sectional views of three embodiments of this invention;

FIG. 6 is a plan view in the direction of arrow A in FIG. 5; and

FIG. 7 is a cross sectionalview along line 7-7 FIG. 5.

Referring now to the drawings in which similar components are designated by the same numerals, the device of FIGS. 1 and 2 is located in the boiler 1 situated on the chassis 2 of the toy locomotive. The support 5 of The invention itself, however, both toy-locomotive.

the boiler is carrying the storage tank 3 containing the liquid to be evaporated. The storage tank 3 has the refill tube 4 through which the tank 3 may be refilled with a visible steam vapor or smoke producing liquid. The refill tube 4 is provided with a cap 7 which has a vent hole 6. The bottom 8 of the tank 3 has a groove 9 which leads into the mouth 10 of the capillary tube 11, which has a degree of capillarity that transports liquids, such as for instance disclosed in my co-pending application Serial No. 852,608, filed November 13, 1959, into the sphere of the heating effect of the heating wire spiral 13. The upper extremity of this capillary tube 11 leads into the stack 12 of the toy-locomotive. The heating wire spiral 13 surrounds the capillary tube -11 and is supported in the concentric casing Y 15 made of ceramic material. The insulating shield 14 prevents the heat of the heating wire spiral 13 to excessively heat the liquid in the tank 3.

When the circuit of the heating wire spiral 13 is closed, the heat produced by the same causes the liquid F which is creeping upwards, due to the capillary action and degree of capillarity in tube 11, to evaporate when it reaches a point in the tube 11 opposite the spiral 13.

The smoke or visible vapor R then leaves the capillary tube 11 which is made of steel, through the opening M.

-The embodiment of FIG. 3 mainly consists of the capillary tube 11 which has a lower extremity that extends into the liquid F. In this embodiment, the heating wire spiral 13 surrounds the upper portion of the capillary tube 11 which runs co axially with the metal housing 16 of the device. The housing 16 is supported and centered by means of an integral flange 16aon the funnel 12 of a The capillary tube 11 is guidingly supported by a small thermally insulated tube 17 of dielectric material which embraces the heating" wire spinal 13 of the heat'producer. The sleeve 17 in turn is supported by two filament current wire connections 18, 19. The small tube 17 is made of ceramic material (of insulating cement or the like) having the aforementioned properties. Inside the wire spiral 13 extends coaxially the sleeve 20, of dielectric but thermally conductive material, from the heating wire connection 19 down to the contact plate 17b. The sleeves 1'7 and 20 are dielectric and packed with respect to the bowl-shaped housing 16. Whereas sleeve 20 consists of thermally conductive material to insure good heat transfer to the capillary tube 11, sleeve 17 consists of heat insulating material, such as ceramic cement. The lower wire connection 13 extends downwardly through a ceramic tube 17:! and ends at the con tact plate 21. The contact plate 21 is urged by the contact plate-spring 22 against the pole of the bulb socket 24. The bulb in the bulb socket 24 is secured therein in a liquid-tight manner so that the liquid F does not leak out through the socket 24. The plate spring 22 is supported by the bridge 23 which is preferably made of synthetic resin. The tube 17a and the disc 17b are also preferably made of heat-proof ceramic insulating material.

The liquid-mark for the liquid F in the housing 16 of the device is designated with the line N. It is, however, possible for the device to properly function even if the housing 16 is erroneously filled up to the flange 16a. Thus the energizing current that produces the heat and thereby evaporates the liquid F in the upper part of the capillary tube 11 flows from the electric current source Q via the contact plate-spring 22, the contact plate 21,

Patented Dec. 15, 1964 e'D the filament current wire connection 18, the heating wire spiral 13, the cap 1%, the heating wire connection 19, the flange 16a, the mass in the form of the boiler 1 which is usually made of zinc die-cast, back to the current source Q; the space 25 between the funnel 12 and the sleeve 16 serves to insulate and thereby protect the funnel 12 of the toy-locomotive. This is necessary since the housing can become very hot in the area of the spiral 13 which would then transmit the heat to the funnel 12 which frequently consists of unhardened synthetic resin and is therefore sensitive to heat. The capillary tube 11 is preferably made of steel and can be easily exchanged by means of tweezers, if it should become clogged or is otherwise rendered unusable.

The embodiment illustrated in FIG. 4 comprises a casing 15 which has a collar 15a by means of which the casing 15 is supported on the insertion piece 26 which is fitted on the upper border of the housing 16; The housing 16 of this embodiment has the overflow opening 27. A switch 28 in the energizing circuit of the devices serves to turn the device on or off. The device may be inserted into an opening of the boiler 1, of a toy-locomotive and is supported therein by a collar 16!).

The embodiment illustrated in FIGS. to 7 has a heating wire spiral 13, spiralled and cemented onto the capillary tube 11. Thecapillary tube 11 is preferably manufactured out of ceramic material and has a tightly fitted cap'29 at its lower end which extends into the metal bush 39. A spoke ring 31 is fitted over the upper end of spiral 13 and serves to support the tube 11 in an upright coaxial position-inside the housing 16. The metal bush 3% is inturn held in position by the insulating ring 33. The aforerecited structural members 31, 13, 11 and 29 can-be easily interchanged with newparts in the event any one or all of them become unusable. The heating wire spiral 13 is located in the following electric circuit:

Power source Q, boiler 1, housing 16, spoke ring 31, heating wire spiral 13, metal bushes 29, 30, cable shoe 34, cable 32, switch 28 and back to power source Q.

Examples of liquids used for producing the smoke or the like are disclosed and described in my co-pending patent application, Serial No. 852,608, filed November 13, 1959, and now abandoned.

The device of the instant invention, when filled with the appropriate liquid and heated, emits intermittently smoke, visible vapor or the like as illustrated with clouds R in FIG. 1 of the drawing, with arr-accompanying pulling noise.

Although the present'invention has been described in conjunction with preferred embodiments, it is to be understood that modifications and variations may be resorted to without departing from the spirit and scope of this invention, as those skilled in the art will readily understand. Such modifications and variations are considered to be within the purview and scope of the invention and appended claims.
