June 6, 1944. Q sc 2,350,740
ELECTRICALLY DRIVEN TOY VEHICLE I Filed 061'" 9, 1940 game/WM Way.
Patented June 6, 1944 ELECTRICALLY DRIVEN TOY VEHICLE Oswald Fischer, Nuremberg, Germany; vested in the Alien Property Custodian Application October 9, 1940, Serial No. 360,486 In Germany September 4, 1939 1 Claim.
This invention concerns an electrically driven toy vehicle or more specifically a vehicle for electrical toy trains, which has a remote control apparatus operated through the energizing of a switch-magnet by means of current contacts.
According to the invention disclosed in patent application Serial #269,797, the apparatus utilies a switch magnet, which places the magnet while it is being operated under the influence of a current, which is stronger and operates to actuate the magnet only when the motor is stopped or running at a low speed. The armature of the switch-magnet, which is only attracted while the change is taking place, is under the influence of a force created for example by a spring, a weight or similar device, Which attempts to keep it in its inactive position and which force is greater than the magnetic force exerted by the current moving the vehicle.
This switching apparatus has a further advantage, in as much as it provides for a means, which stops the operation of the switch magnet while the motor is still running. Such a checking device can serve a mechanical apparatus, which can for example prevent the swaying movement of the armature of the switch magnet while the motor is running or an electrical device, which will interrupt the circuit to the switch magnet while the motor is running by means of a contact device.
It is especially advantageous to regulate this checking device through the motor.
By means of this invention it can be accom plished, that the switching can only be done when the vehicle is substantially at a standstill or just starting. A detrimental effect due to heavy wear and tear on the parts because of accidental switching while in motion is impossible with the present invention. Besides, inasmuch as the switching magnet is turned ofi while the motor is running, an undesired self-switching of the vehicle because of current interruptions while the vehicle is in motion does not take place.
Fig. 1 is a diagrammatic view showing one form of my invention and Fig. 2 is a detail view of the motor operated circuit breaker.
When the vehicle is moving and thus the motor is running the current flows from its source Q (transformer) through wire Z controlling switch C including the movable contact 7c and stationary contact k and k wire Z field of motor M, reversing switch armature of motor M reversing switch 0 conductor Z", current source Q.
If the motor M is not running and should be switched, the contact is will be moved in contact k bridging resistance R, and consequently the highest voltage will be attained. The current thus flows from its source Q over the wire Z the contact points k. W, the wires Z 1* motor-operated switch P and l to the switch magnet S and over the wires 1 and 1' back to the source Q. The switch magnet S therefore becomes active so that its armature A is attracted, also the connected reversing switch apparatus 0, which is shown as a drum.
To switch the currents over the wires 1*, 1 1, and to the switch magnet S while the motor is running, there is provided a lever H, which thus operates the switch P. As soon as the motor starts to rotate, the lever H will be freed and the switch P opened. The switch magnet S is turned off.
The switch magnet S may be employed for a. variety of purposes such, for example, as to operate a reversing switch for the motor, train lights, or signal lights, couplers, or for operating switch points on the tracks.
Fig. 2, shows the specific construction of the circuit breaker P. In this construction the movable contact H is frictionally mounted on the motor shaft. This contact when the motor is not running, is normally held in engagement with a stationary contact F by means of a spring I. When the motor M is running the arm H has broken the circuit to the relay S and is in engagement with one of the stationary stops m m The invention is not only applicable to switch arrangements but is also adaptable for other long distance steering switch arrangements, which operate through interchanging of the switch magnets under current voltage.
What I claim is:
In a system for electrically driven toy vehicles an electric circuit including a driving motor and a switch magnet having an armature, means urging said armature to inoperative position, means for applying relatively high and low voltage to said circuit, said magnet being operable to move said armature to operative position only on application of said high voltage, and means operable when said motor has started for interrupting current through said switch magnet, said last named means including a fixed contact, a shaft movable with the motor, a contact arm frictionally mounted on said shaft and adapted to engage said fixed contact and to be moved by movement of said motor away from said fixed contact, and means urging said arm into engagement with said fixed contact.
