' 9 Claims. (01. 104 451) The present invention relates to controlling mechanisms for electric trains and embodies, more specifically, an improved control for a toy electric; train by-means of; which the locomotive we may'be'started and stopped intermittently, the direction of travel of the locomotive being changed 'atwill each time-.the locomotive is started. e Inexisting forms. of trains,a form of control 510 is provided in which a reversing switch is utilized for reversingthe directionof travel ofthe locomotive when the power is againapplied thereto after having been shut off. This control switch is operated by asolenoid which is in par- ;1; allel with the locomotive motor-and is automaticall'yudisconnectedby a switch which is opened when the locomotive motor is energized. the solenoid and is mannerythe direction of must be reversed each started again. The difiiculty of incorporating a more sensitive control'in theses'mallmechanisms isconsiderable and theexpense thereof, together with" other considerations, has prevented-such form of control from being used. 1 An object of'the present: invention, therefore, is to providea controlling mechanism for locomotives of the above character, such mechanism enabling' the locomotive to be operated in either forward or reverse direction:atwilrregardless of the manner inwhich power' is supplied thereto.
A further object of the invention is to provide a control of the above character which is simple in construction and operation, and is readily applied to standard forms and makes of locomotives.
A further object of the invention is to provide a control of the above character which is inexpensive in construction and installation and effective in operation.
A further object of the invention is to provide a mechanism operated by an auxiliary electrical circuit, which will control the operation of solenoid reversing switches on toy electric trains designed to run on alternating current.
A further object of the invention is to provide an auxiliary circuit of such nature that the current it allows to pass will not move the locomotive, but which will be sufiicient to operate the mechanism controlling the solenoid reverser described above.
. Further objects, not specifically enumerated above, "will be apparent as. the; invention dee scribed ingreater detail-in connection with the accompanying drawing in which the singletfigure represents, diagrammatically, the connections and elementsbymeans of which-the locomotive isv controlled as desired.
Inthe drawing, a designates an, electricmotor having a reversing switch b connected thereto; for reversing thepolarity of the armaturewith respect tothe fields and thus reversing the dis rection oi travel of the locomotive. A solenoid 0' having a plunger c operates the reversing switch and is connected in parallel with the driva butterfly switch dis in the closed position. The butterfly switch. (1 is piv-.- oted in the motor truck frame ate! .and isthus electrically connected to driving wheels 2 which, when resting on the rails,be'come. the ground leg e ofthe driving circuit. The butterfly switch is weighted'in such a manner that thercontacts c? are normally. closed, Terminal b of the cons troller b is grounded to the truck frame :andthe Wheels e. The wheels re engaging .the ground rails-e, are connected to the power/transformer j by an external wire 2 The other terminal-of the controller b is connected-tothe third rail i by wire h. The thirdrail i is connectedtoi'the The transformer f uses as a power supply, 110 volts alternating current by .meansflof. the plug f. The output ofthe transformer is .varie ableand is normally set-at=-19- 21 volts..-i .I i
- Theoperation of this portion ofthe circuit is such that when current is applied from the transformer through wires g and h and the ground connection e3, the solenoid c is energized (switch at being closed) and the reversing switch is operated. Simultaneously, the field of the motor a is energized and the butterfly switch (I is attracted by the field pole piece, thus breaking the circuit through the solenoid c. The butterfly d is held in the open position, after the current has been shut off, by the residual magnetism in the core k of magnet k.
In the circuit included by wire h, a magnet is is connected. This magnet has a core k which projects in close proximity to the right hand end of the butterfly switch d, preferably leaving only .001 inch of gap between the core and switch when the latter is attracted by the field of motor a. Between the power transformer and third rail, the wire 9' is connected to two circuits in parallel. The main circuit designated 9 includes a variable ALI resistance m and switch m while the other, auxiliary circuit g includes a fixed resistance 1 and switch Z. When switch Z is closed, the fixed resistance Z is in series with magnet k, motor a and solenoid c. The resistance of this circuit is such that the current flowing at this time is insufficient to operate the motor a and solenoid 0 but is surficient to destroy the residual magnetism of the soft iron core k of the magnet k (it being remembered that the system operates upon alternating current). Upon destroying the residual magnetism of core k the butterfly switch d drops to its closed position. If the switch m is now closed, current and motor a, actuating the reversing mechanism and reversing the direction of travel of the locomotive.
From the foregoing description, it will be seenthat opening and closing the switch m will cause the locomotive to be stopped and started in the forward direction. If it is desired to reverse the direction of travel of the locomotive, switch I is first closed, destroying the residual magnestism of core k and permitting the switch d to close, and then the switch m is closed in the usual manner. The speed of the engine is varied by varying the resistance m, this being the usual practice in existing designs. It is necessary that the current flowing through the switch Z and resistance Z be insufficient to operate the motor and solenoid but sufficient to destroy the residual magnestism in the magnet core This permits practically full voltage to be impressed upon the motors and electromagnets but limits the amount of current so that the locomotive is not started when'the switch'l is closed.
It will be apparent that the invention may be modified to adapt it to various forms of locomotives and connections and the arrangement of parts may be varied as desired without departing from the scope of the invention as defined in the appended claims.
I claim as my invention:
1. A control for an electrictrain comprising a motor, a reversing switch for the motor, means in parallel with the motor for operating the switch, means in series with the motor for preventing operation of the switch operating means, a switch and variable resistance for the motor, and an auxiliary switch and resistance in parallel with the switch and variable resistance for controlling the means for preventing operation of the switch operating means.
