BATTERY LIGHTED LOCOMOTIVE TOY Pennsylvania Application September 21, 1933, Serial No. 690,317

6 Claims.

This invention relates to battery operated electrically lighted toys and more particularly to a battery lighted locomotive toy.

The primary object of my invention is to generally improve battery operated electrically lighted toys. A more particular object, of my invention resides in the provision of a battery operated electric lighting system for a toy locomotive of the mechanically operated or spring drive type.

Further objects of my invention are to provide room for the battery cell while permitting the motor mechanism to project upwardly into the boiler shell; to help balance the weight of the locomotive about the driving wheels, and to increase the weight and improve traction of the locomotive; to dispense with the necessity of connecting and disconnecting conductors between the locomotive and the tender or other attached cars; to make the lighting system operative when the locomotive is off the track so that it may be displayed on the counter of a store, or used when running the toy on the floor instead of on a track; to improve the appearance of the locomotive by filling in the under-carriage structure; to provide a battery support afiording ready removal and replacement of the battery cell, and effective and dependable electrical contact with the battery cell; to devise a simple wiring system necessitating only a single short conductor and dispensing with soldering; and to combine with the lighting system a switch providing either bright, dim or no energization of the headlight as may be desired.

To the accomplishment of the foregoing and such other objects as will hereinafter appear, my invention resides in the toy locomotive and battery lighting elements and their relation one to the other, as hereinafter are more particularly described in the specification and sought to be defined in the claims. The specification is accompanied by a drawing, in which:

Fig. 1 is a side elevation of a locomotive toy embodying features of my invention;

Fig. 2 is a rear elevation thereof;

Fig. 3 is a partially sectioned plan view sectioned in the plane of the line 33 of Fig. 2;

Fig. 4 is a side elevation of the locomotive cab looking from the side opposite that shown in Fig. 1;

Fig. 5 is a partially sectioned plan view showing a modified form of switch mechanism;

Fig. 6 is a vertical section taken in the plane of line 66 of Fig. 5; and

Fig. '7 is a modified switch element for use in the structure of Figs. 1 through 4.

Referring to the drawing and more particularly to Figs. 1 through 4 thereof, the toy locomotive may be conventional in comprising a boiler shell l2 beneath which there is mounted spring driven locomotive works 14, the upper portion projecting into the hollow boiler shell l2. Because of the resulting compact and crowded construction, it is not convenient to mount a battery cell in the boiler shell, and in accordance with the present invention, a battery cell it is mounted in an upright position in the cab N3 of the locomotive. The locomotive is provided with a headlight 20. preferably of the flashlight battery type, received in a socket 22 mounted on the front header 24 of the boiler shell. The energization of headlight 20 is controlled by appropriate switch mechanism 26 located in the cab of the locomotive and preferably contacting directly with the battery cell l6.

Considering the structure in greater detail, the locomotive body is made up of a pressed sheet metal chassis member 30, the side edges of which are bent downwardly to form side flanges 32, the rear edge of which is bent downwardly to form a rear flange 34 and a coupler 36, and the front portion of which is bent downwardly to form the bumper supports 38. The bumper 4| and pistons 43 may be formed separately and are mounted on the chassis by conventional tongue and slot connections. The boiler shell 12 may be formed out of a single piece of sheet metal bent to an inverted trough-shape and having its lower side edges secured to the top surface of chassis 30 by tongue and slot connec tions. The boiler shell may, if desired, be surmounted with pressed sheet metal elements simulating a smoke stack 40, steam domes 42 and 44 and a bell 46. Hand rails 48 may also be provided.

The cab l8 includes a floor or bottom wall 5|] formed by the chassis member 30 and a roof 52 and side Walls 54 formed by a rearward continuation or extension of the boiler shell 12. The locomotive works i4 may be of conventional type and need not be described in detail. It may be mentioned, however, that the bottom of the chassis member 30 is cut away to receive the upper portion of the locomotive works, the latter passing upwardly into the hollow boiler shell [2.

The lamp socket 2! may be of any desired type and in the present case comprises a threaded sleeve having an outwardly flanged forward edge 56 held in place by lugs 58 bent inwardly from the front wall of the boiler header or closure 2d. The socket is thus grounded directly on the body of the toy. The rear end of the socket is provided with an insulation disc having a center contact, not shown, through which center contact there is connected a conductor til.

Battery cell It is of the conventional flashlight type and is pushed upwardly into the cab through a mating aperture cut in the floor 55] of the cab. A part of the cut away material is preferably bent upwardly to form the support lugs 52, best shown in Figs. 2 and 3. These support lugs may, if desired, be so positioned as to bear inwardly against the cardboard wrapper surrounding the zinc casing of the cell and thus help to position the cell fixedly in place.

The cell is additionally supported by a U- shaped battery support or strap fi l which is preferably detachably secured to the depending side flanges 32 of the locomotive chassis. In the present case, one of the side walls is provided with a pair of outwardly bent lugs 85 which pass through mating slots in one of the side flanges 32, as is best shown in Figs. 1 and 2. The other side wall is preferably provided with an outwardly struck tab 68 cooperating with a mating slot or window Til as is best shown in Figs. 2 and 4. The bottom wall of the battery support is preferably struck upwardly to form a resilient contact finger 12, having an upward dot or teat l4 for contacting in a dependable manner with the exposed bottom of the battery cell. It will be understood that to change the batmry cell, it would be a simple matter to press the side walls of the support together enough to release the latch or tab 68. While open, the support may be swung downwardly about the lugs 66 and freed entirely from the locomotive. The cell is 4 then removed and replaced by a new one, after which the lugs 66 of the support may be engaged in the mating slots and the opposite side of the support then pressed upwardly until latch 68 snaps into position in the slot it.

The switch mechanism 26 is embodied in the present case by a single strip of insulation 89 which, as is best shown in Fig. 3, is narrowed at the ends thereof. The insulation strip passes slidably through mating slots in the side Walls 54 of the cab. In efiect, a slide is provided which may be moved from one side to the other by pressing upon the outwardly projecting ends, and the motion of which is limited by the shoulders formed within the reduced ends of the slide. This insulation slide is so located as to bear against the positive pole $2 of battery cell it. The slide 88 is provided with spaced contacts't i and 85 which pass through slots in the slide and are clinched in place. These contacts are interconnected by a small bare wire resistor 88, the ends of the resistor being pinched by the contacts and thus held without soldering. One of the lugs, in this case the lug 86, is also connected to the end of conductor 66 which extends to the headlight.

It will be readily appreciated that by leaving the slide in mid-position, as shown in Figs. 2. and 3, the battery circuit is opened and the light extinguished. By moving the slide so as to bring contact 84 against pole 82, the headlight is energized with the full potential of the battery cell, resulting in bright illumination. If the switch is moved in the opposite direction, bringing the contact 86 against the pole 82, the light is energized through resistor 88, resulting in dim illumination.

A generally similar switch construction may, if desired,. be used in simplified form when no choice of bright and dim illumination is to be provided. For this purpose, only a single contact is needed and the resistor may be omitted. Such a construction is shown in Fig. 7, in which the switch includes the insulation strip 98 and a single contact 92 formed by coiling the end of wire 66 around through slots in slide 99.

A modified form of switch arrangement is shown in Figs. 5 and 6. In this construction, a slab, or strip of insulation IE3 is stationarily mounted at the top of the cab, as by riveting the forward end of the insulation to the top of the boiler shell by means of rivets 12 located within the steam dome M. The insulation member 198 is provided with a contact eyelet Hit, the lower side of which bears against the pole 82 of the battery cell and the upper side of which acts as a switch contact cooperating with a metallic switch lever Hit. The forward end of switch lever lilfi'is pivoted on the insulation base 590 by means of an eyelet M8 to which eyelet the conductor 65) is connected. It will be evident that upon moving the switch lever Hi8 from the 01? position shown in Fig. 5 to the position above eyelet I641, the battery circuit will be closed and the headlight energized. To insure a firm contact between the switch lever and contact H34, a finger I It! may be struck downwardly from the movable end of the switch lever and positioned for sliding engagement with the bottom of the insulation base Hill, as is best shown in Fig. 6. The end H2 of the insulation base is, of course, shaped on an are having pivot I 58 as a center.

The battery cell it is shown located at one side of the cab in order to provide ample clearance for control lever $28 which looks or releases the motor of the locomotive. If no such lever is provided, or if the lever is located at the side wall of the cab, the battery cell may, of course, be located central-1y in the cab and the switch mechanism modified to properly coact with the battery cell in its new location.

It is believed that the mode of constructing and using, as well as the many advantages of my improved lighting system will be apparent from the foregoing detailed description thereof. Ample clearance is retained in the boiler shell for the locomotive works, the battery being located in the cab. The battery increases the weight and traction of the locomotive and its location in the cab is particularly advantageous because it helps balance the weight of the locomotive about the wheels. The lighting system being complete and self-contained in the locomotive, no complication is introduced when coupling or uncoupling the locomotive from the tender or remaining cars of the train. The light may be energized even when the locomotive is oil the track, this'being of value when displaying the toy in a store, and also because it permits a child to play with the toy upon the floor without setting up a track system. The switch mechanism is conveniently operable, is located in the cab, and is extremely simple and inexpensive. Withbut slight change in construction, a choice of either bright or dim i1- lumination is made available. The battery support hero employed improves the appearance of the locomotive because it fills in the sides of the locomotive at the under-carriage. The battery is conveniently replaceable. Dependable contact is provided at the bottom and top or the battery without close manufacturing tolerance. Only a single wire is needed and this may be secured in place if desired without necessitating soldering. The battery is held securely in place and is substantially completely concealed by the cab and underslung battery support.

It will therefore be apparent that while I have shown and described my invention in preferred forms, many changes and modifications may be made in the structures disclosed without departing from the spirit of the invention, defined in the following claims.
