Toy sMoxE-PRoDuCING APPARATUS Filed Dec. 16. 1947 Patented Nov. 10, 195:;

OFFICE TOY SMOKE-PRODUCING APPARATUS Frank Pettit, Union, N. J assigner to The Lionel Corporation, New York, N. Y., a corporation of New York Application December 16, 1947, Serial No. 792,108

(Cl. L16--9) 6 Claims.

The present invention relates to toy smokeproducing apparatus and is more particularly directed. toward the production oi smoke in toy locomotives.

To create the illusion of the ordinary puffing steam locomotive it is desirable to provide means in the locomotive for producing pus of smoke or smoke-like material so that the operation of the locomotive will be more realistic as it travels along the track.

The present invention contemplates an improved smoke-producing apparatus according to which the smoke-producing material is carried in a substantially closed electrically heated retort and means are provided for producing intermittent blasts oi air which are directed into the smoke vapors in the retort so that some of them are expelled through an upwardly extendu ing flue.

The present invention contemplates an air pump operable by the moving locomotive and acting to produce intermittent air jets which are transmitted to the smoke chamber whiie no return of iiow or air from the smoke chamber toward the pump is possible during the suction stroke of the pump.

`Other and further objects will appear as the description proceeds.

The accompanying drawings show, for purposes of illustrating the present invention, one embodiment in which the invention may take form, it being understood that the drawings are illustrative of the invention rather than limiting the same.

In the drawings:

Figure l is a vertical longitudinal sectional view through the front part oi a toy locomotive showing the smoke-producing apparatus.

Figure 2 is a top plan view with parts in section along the line 2--2 of Figure l; and

Figure 3 is an exploded vertical sectional View taken on the line of Figure 2.

The locomotive is provided with a chassis or body iii of any convenient type. A pair of driving wheels indicated at il, Il is carried on an axle I2 which carries a cam It adapted to engage a bent lever ifi anchored at its left end as indicated at i5. This lever is received in a slot i'a in the body lil and is adapted to be shifted irorn the full line to the dotted line positions as the cam revolves.

The smoke unit is secured near the iront of the locomotive, it being carried by a bracket 2i] as indicated. This bracket carries a downwardly opening cylinder 2i and the cylinder receives an inverted cup-like piston 22 which rests on the 2 free end 23 oi the lever id. The upper end of the piston and the bracket are apertured as indicated at 2t so that on the up stroke of the piston a strong jet of air is forced out through these apertures.

The bracket carries a die cast housing 25 which has a central boss 2t to space the bottom wall 2i' of the housing above the bracket. The housing has a cup-shaped receiver 2E and a hole fie aligned with the holes 2li and extending from the bottom face 2i of the housing to the top. This hole is preferably tapered as indicated in the drawing. A sheet of insulation extends across the bottom oi the receiver. A resistance heater 3| is mounted above this sheet of insulation and sheet metal lead-in strips 32, 32 eX- tend out through notches 33 in the outer wall of the housing. These strips are covered with insulation. A sheet metal cover fits tightly about the upper part of the housing. This cover has a flue opening 35 oi reduced diameter. It is received in the cover oi the locomotive.

A pellet o1 smoke-producing material such as a wax, which will melt when heated, may be dropped through the nue. This material should be of such a nature that it will not impair resistance heaters at the high temperature required for volatilization. The heating current received from the locomotive circuit will act to volatilize this material and produce a volume of smoke vapors in the retort. These do not readily escape because the small hole 29 does not provide enough air for strong convection currents. The vapors condense in the chamber and are returned.

When the locomotive is moving along the track the pump is in operation and this produces a strong blast of air or jet which passes through the opening 2li and into the passageway 29 thereby forcing a blast oi air into the retort and causing a puff of smoke to be blown out. When the piston of the pump descends, air is drawn in through the holes 2t but as these holes are not in communication with the hole 29 there is no reverse suction of air from the retort chamber to the pump. This avoids wasting the smoke-producing material and keeps it out of the pump or the interior of the locomotive.

Since it is obvious that the invention may be embodied in other forms and construction within the scope of the claims, I wish it to be understood that the particular forms shown are but a few of these forms, and various modifications and changes being possible, I do not otherwise limit myself in any way with respect thereto.

What is claimed is:

1. In a toy smoke-producing apparatus, in combination, a pump having a reciprocating piston and a cylinder having a tiny port in its end, through which air compressed in the cylinder escapes as a jet, and a smoke generating retort iixeolly disposed relative to the pump and provided with an exhaust flue andv having an injection passageway with its inlet end open to the atmosphere for aspiration of air in addition to the air in the jet and transmitting the same into the retort, the passageway being aligned with the port to accept the jet of air expelled there through and the entrappedair but spaced from the port so that air can enter the cylinder through the port without going through the pasu sageway.

2. A toy smoke-producing apparatus as claimed in claim 1, wherein the flue is vertical and above the bottom of the retort to admit smoke-producing material and the retort has an electric resistance heater.

3. A smoke-producing toy locomotive having driving wheels, a cam driven with the wheels, a xed cylinder, a reciprocable piston in the cylinder drivingly connected to the caro, the cylinder having a tiny port in its end` through which air compressed in the cylinder escapes as a jet, a retort i'ixedly disposed relative to the cylinder spaced from the end oi the cylinder and having a passageway aligned with the port and its adjacent end open to the outside air so that on the suction stroke oi the piston air enters through the port without going through the passageway and on the compression stroke the expelled air forms a jet adapted to enter the passageway, the retort having a smoke generating chamber into which the passageway opens and an exhaust port for expulsion of vapors.

4. In a smoke-producing toy, a housing having a cup-shaped receiver for smoke-producing material, the housing wall having a vertical passageway lateral of and close to the receiver and opening downwardly and upwardly, a cover over the x. housing, the cover being spaced above the upper end of the passageway and having an exhaust flue, an electric heater in the receiver, and means for producing intermittent one way blasts of air directed upwardly through the passageway.

5. In a smoke-producing toy, a housing having a cup-shaped receiver for smoke producing rnaterial, the housing wall having a Vertical passageway lateral of and close to the receiver and opening downwardly and upwardly, a cover over the housing, the cover being spaced above the upper end of the passageway and having an exhaust iiue, an electric heater in the receiver, and a reciprocating pump fixedly disposed relative to the receiver and having a .iet forming port aligned with but spacedv from the lower end of the passageway.

6. A device for producing a succession of puffs of smoke to simulate the smoke from a locoinotive stack which comprises a smoke generating retort having an electrically heated receiver for smoke producing material whereby the retort may be kept lled with smoky vapors, an exhaust ue above the receiver, means providing a relatively srnall air injection passageway with its outlet end opening into the retort and its inlet end open to the atmospherey so that fresh air may enter the retort through the same, and means for eiecting unidirectional intermittent blasts of fresh air through the inlet opening of the injection passageway to expel some of the vapors through the flue.
