14 Claims.

erally improve electrically lighted toys, particularly vehicle toys having simulated head lights, by the provision of optionally usable bright or dim lighting of said head lights. A more particular object of the present invention is to accomplish the desired control or switching of the lights without necessitating a change in the number of battery cells employed, thereby making the arrangement particularly useful for toys having only a single battery cell, and, in a broader aspect, making the system of my invention applicable to toys receiving their electrical energy from a constant potential source, as in the case of track toys.

Further objects of my invention are to provide for the desired control of illumination in an inexpensive manner so that the necessary switching arrangement may be made and applied to the toy without noticeably increasing the cost of manufacture and the sales price of the toy; to concentrate all of the necessary insulation for the switching or control system into a single relatively small piece of insulation which may be stamped to desired configuration in a single stamping operation; to devise a complete switching system devoid of soldered connections and dispensing entirely with soldering; and to minimize the necessary wiring for the lighting system of the toy, and, in fact, in some cases to dispense entirely with Wiring.

To the accomplishment of the foregoing and such other objects as will hereinafter appear,

my invention consists in the electrically lighted oy arrangement for bright and dim illumination, and the elements thereof 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 drawing, in which:

Fig. 6 is 'a vertical section through the toy in upright position, this section being taken in the plane of the line 66 in Fig. 5;

Fig. '7 is a side elevation of the dimmer switch used in the truck hauler toy; and

Fig. 8 is a vertical section through a fire patrol toy embodying still another form of my invention.

Referring to the drawing and more particularly to Figs. 1 to 4 thereof, the invention is there shown applied to a toy locomotive comprising a toy body 12 including a boiler shell 14 the front end of which is closed by a header 16. The toy is provided with a flashlight bulb 20 which is screwed into a mating hole .18 in the header, 16 the base 22 of the bulb passing through the header and extending into the boiler shell cavity.

The illumination of the bulb is accomplished by'the use of battery cells 24 and 26, preferably of the cylindrical flashlight type, which are received in end to end relation within the boiler shell 14.. Specifically, the otherwise open bottom of the boiler shell is closed by an elongated trough-like support 28 the side edges of which are received above and supported by inwardly projecting beads 30 defining the lower edge of the boiler shell, and the support 28 is restrained from longitudinal movement by one or more tongues 32 passing through a mating slot in the header 16. .If desired, straps 34 may be struck downwardly from the side walls of support 28 and bent outwardly to fit beneath the side beads 30, thereby locking the support in place against upward movement.

The battery cells 24 and 26 are slid into the boiler shell through the open rear end thereof and are confined between the top of the boiler shell and the bottom support 28. In the particular arrangement here shown, the cells are each inserted zinc-base foremost, thereby bringing the zinc base 36 of cell 24 adjacent the head light bulb 20 and connecting the cells in series by reason of the contact between the positive pole 38 of cell 24 with the zinc base 40 of cell 26. The cells are held against axial movement by a preferably resilient end stop 42 consisting essentially of an L-shaped strip of spring metal the shorter arm of which bears against the positive pole 44 of battery cell 26, and the longer arm of which is detachably secured to the battery support 28. Specifically, the battery support is transversely slit, and astrap of metal 46 illumination results.

recess 48 springs around teat 50, thereby lock-' ing the end stop and the cells in position. Forremoval, the tab 49 is first bent downwardly.

The control of the head light bulb for bright or dim illumination is accomplished byv the use of a series resistance and appropriate switch mechanism for cutting the resistance into or out of circuit. At the same time, the switch mechanism preferably is also arranged to open the circuit when desired. In the present: case I the switch comprises a single slab or strip of insulation 60, best shown in Fig. 4, which extends horizontally across the front portion of the boiler shell with its ends 62 protruding outwardly therefrom, as will be clearly evident from an' inspection of Figs. 1 and 3.: By. reciprocating the switch member 60 from one side to the other, the head light may be burned brightly, dimmed, or extinguished.

To accomplish this desired result, the interinediate portion of the insulation memberfiGO-is provided with spaced metallic contacts 64 and 66 interconnected by'a tiny helical resistance element '70 which extends between the contacts 64 and 66 and which iscarried by and movable with'the switch member 60. One of the contacts, say, the contact 64, consists simply of a U-shaped clip of metal passed through slots on the switch member and clinched on the rear face thereoffas will be evident from an inspection of Figs. 3 and 4 of the drawing. The other contact, in this case the contact 66, is likewise passedthrough slots on the switch element and is clinched in'place, but'contact 66 differs importantly from contact 64 in having av rearwar'dly-projec'ting wiper 68'formed on the rear face of the switch. The switch is positioned directly behind the center contact "12 of the lamp bulb, so that movement of the switch toward one side or the other brings either thecontact 64 or the contact 66 against the .terminal '12 of the bulb, while in. the middle or center position the terminal '72 bears simply against in-- sulation' This middle position be better determined by the provision of a centering, hole 74in the switch member.

In operation, the spring stop member 42 urges the battery cells into contact with" one another and into contact with the wiper 68. The positive pole of battery cell 26 is grounded by the spring stop 42, and oneterminal of the lamp 20 'is grounded to the header in which it'is screwed. When the switch member is so moved as to bring contact 66 against terminal 72 of the lamp, a circuit is completed through the cells and lamp, and the full voltage of the battery is applied'directly to the lamp. When, however, the switch is moved .in the opposite direction,- bringing the contact 64 against terminal '72, the circuit completed throughthe dimming resistor 70, forthe zinc b'ase 36 of cell 24 bears against wiper 68 which in turn is connected through resistor 70 to thecontact 64. Of course, when the switch member is centrally disposedthe battery circuit is opened and no It is important to notice that the construction herein shown requires no soldering at any point, and, in fact, requires no wiring, one terminal of the battery being grounded through the spring stop 42, and the other terminal being directly applied to the switch and thence to the lamp bulb. The resistor itself is tiny, inexpensive, and inconspicuously mounted on the slidable switch member. No difficulty of soldering the relatively hard resistor wire arises because the end terminals thereof are simply passed beneath the contacts 64 and 66 when the latter are being clinched onto the switch element, this construction being evident from an inspection of Figs. 2 and 4.

Another feature of the battery holder disclosed in this locomotive toy is its adaptation for receiving either one or two battery cells. For this purpose the support 28 is slotted at and is provided with a downwardly struck strap 82, similar, to the strap 46 previously mentioned, and a teat 84 similar to the teat 5O heretofore described. This. construction constitutes a means for receiving the spring stop 42 and permitting the same to bear against the positive pole 38 of a single battery cell 24 when it is not desired to use two battery cells in series. When-using a single battery cell, the procedure is to slide the battery cell in place and to then insert the vertical arm of spring stop 42 through the slot 86 while passing the horizontal arm of springstop 42 through strap 82 and into engagementwith teat 84. The holder is thereby equally well adapted for the accommodation of either one or two battery cells, and when using a single battery cell the same bulb may be retained, for dimmer illumination, or a lower voltpurposes it may be generally considered as a vehicle toy having head light bu1bs 90 and 92 mounted on front mudguards 94, and a battery cell 96 mounted substantially below the bottom of the toy, or, in any case, in a relatively low position on the toy. Fig. 5 is an inverted plan view showing the wheels and axles of the toy and the-battery 96 whichis placed in a recess inlthe bottom of the toy and held against the recess by a wire yoke-98 at the ends 100 of which are slidinto straps 102 struck downwardly from the bottom of the toy. The zinc base 104 of the cell bears against. a contact lug 166 and is grounded thereby. The positive pole 108 of the cell is employed as a fixed contact cooperating with switch means to produce bright and dim illumination of the toy. V

Referring to Figs. 6 and '7, the switch includes a generally upright metallic arm 110 pivoted at 112 on an upwardly struck pedestal 114. The lower end of the switch arm consists of a generally'T-shaped piece of insulation 116 which is'secured tothe metallic switch arm 110 at 118. The insulation member 116 is provided with spaced metallic contacts 120 and 122 which are passed through slots near the side edges of the switch member and clinched therearound.

A resistor 124 is connected between the contacts n battery cell..IIt will thus-bev evident that upon oscillation of switch lever 116 about the fixed fulcrum 112,-the contacts are moved to one side or the other, thereby bringing either contact into sliding engagement with the positive pole 108 of i the battery.

One of the contacts, in this case the contact 120, has secured thereto during the clinching operation the bare ends of a pair of insulated conductors 130 and 132, these conductors extending along the bottom of the vehicle toy and passing upwardly through holes 134 in the mudguards and thence into the housings 136 for the head lights and 92. In the present case the conductor 130 feeds the lamp 90, While the conductor 132 feeds the lamp 92. It will be understood that the other terminals of the lamp bulbs are grounded to the body of the vehicle toy; thereby completing a circuit to the contact lug 106 which bears against and grounds the zinc base 104 of the battery cell.

The operation of the toy is practically selfevident, the lights being extinguished when the control arm 110 is in vertical position, the lights being brightly illuminated when the control arm oscillated to the left, as viewed in Fig. 7, for then contact 120 bears against the battery pole and applies the full battery voltage to the wires 130and 132, and, finally, the lights being dimly lighted when the lever 110 is oscillated to the :ight, as viewed in Fig. 6, thereby bringing contact 122 against the battery pole and connecting the light dimming resistor 124 in the supply circuit'.

Still another form of toy is schematically in dicated by the section of Fig. 8, showing the electrical features thereof. The particular toy hereinvolved is a fire patrol toy which is provided with a pair of head light bulbs 150 and 152, WhlCh bulbs are preferably colored red in order to add realism to. the appearance of the toy. The body portion of the toy carries a battery cell 154 mounted above the bottom 156 of the toy body, for this battery cell may be housed in a casing 158 which simulates a part of the fire fighting apparatus of the fire patrol toy. In this casethe switching of the lights is controlled by a generally upright lever 160 which is pivoted at its bottom end 162. The lever may be made entirely from a suitable piece of fibre or like insulation and is widened at anintermediate portion to carry a pair of spaced contacts 164 and 166 which are clinched in place, much as has already been described. The contacts are ona level with the positive pole 168 of the battery cell and are adapted to bear against the same when the lever is oscillated to one side or the other. While contacts 164 and 166 are clinched in place, an appropriate resistor 1'20 is connected therebetween, the resistor preferably being located on the side of the lever opposite the battery. A pair of conductors 1'72 and 174 are also connected to one of the contacts, in this case the contact 166. The opposite ends of these conductors extend to the head lights 156 and 152, just as in the case of the truck hauler toy shown in Figs. 5, 6 and 7. The present ar rangement of switch lever is especially desirable when the battery is mounted up within the vehicle, instead of at the bottom as in the truck hauler toy.

In operation, it Will be understood that the lights are extinguished when the switch lever 160 is in vertical position; that the lights are brightly illuminated when the lever is oscillated to one side, bringing the contact 166 against the positive pole 168 of the battery; and that the lights are dimly illuminated when the switch lever is oppositely moved, thereby bringing the contact 16 against the positive pole 168 of the battery, for in the latter case the resistor 170 is connected in series with the l.mp circuit.

It isbelieved that the mode of constructing and using the electrically lighted vehicle toys of my invention, arranged for bright and dim lighting, andthe many advantages thereof, will be apparent'from the foregoing detailed description thereof. The toys are made far more effec tive and appealing when provided with the bright and dim featur and add greatly to the popularity of this class of toy. The dimming feature as well as a three-position switch control providing bright, dim, or no illumination, are available without changing the number of batteries used and are therefore applicable to relatively simple and inexpensive toys having only a single battery cell. The switcharrangement is itself compact and inexpensive andmay be applied to the toy without appreciable increase in cost. Only a single piece of insulation is needed for the complete switching arrangement; no soldering is required; and wiring for the light system is minimized, or, in the case of the locomotive toy, entirely eliminated, and in the latter toy either one or two battery cells may be employed, as desired.

The dimmer switch may also be used with track toys, having a third rail for energization, instead of batteries, or with toys having 'tionaliy movable to any of three positions for providing bright, dim, or no illumination from the bulb, said switch mechanism including a stationary contact and a movable control ele* ment and a pair of spaced contacts mounted thereon and interconnected by a resistor also mounted on said control element and movable therewith, and means electrically connecting the toy body, theswitch mechanism, and the bulb in series.
