Description
Patented May 27, 1941 conraormra roa TOY TRAINS Anthony Ehret, Hillside, N. J., assignor to The Lionel Corporation, New York, N. Y., a corporation of New York Application March 16, 1940, Serial No. 324,329
Claims.
The present invention relates to controllers for toy trains, and is more particularly directed toward controllers suitable for use in starting, stopping and reversing a toy locomotive, and for the operation of a whistle or other relay controlled accessory on the train,
The form of relay used for the Whistle motor circuit or other accessory is of the type which does not respond to alternating current of the voltage available in the toy railroad circuit, but
does respond to a small superposed direct cur rent so that it is sensitive to the modified current, and the present controller is one particularly well adapted to efiect the induction of the direct current component.
The reversing mechanism commonly used in a toy electric locomotive is of the type which operates in response to an opening of the current supply circuit to the locomotive. It is adapted to be controlled by an impulse sender which operates a relay to first open the circuit of the propulsion motor without opening the circuit for the other accessories on the train, and then on the next impulse reestablish the circuit for the motor reversing the field or armature so that the motor operates in the other direction.
With such reversible locomotives it is important that the controller used to introduce a direct current component into the power supply circuit should not open the power circuit, and the present controller is one which is particularly designed to maintain the closed circuit relation at all times, except when the reverse button is manipulated.
The accompanying drawing shows, for purposes of illustrating the present invention, one of the many embodiments in which the invention may take form, it being understood that the drawing is illustrative of the invention rather than limiting the same.
In the drawing:
Figure l is a perspective View of a controller unit showing how it is connected to the track;
Figure 2 is an inverted plan View of the controller unit of Figure 1, the bottom cover plate being removed;
Figure 3 is a cross sectional view taken on the line 3-3 of Figure 2; and
Figure 4 illustrates the complete wiring diagram for a reversible locomotive and whistle.
In the arrangement shown in the drawing the alternating current source such as a transformer is indicated at l9. It may have a variable voltage output, if desired, but for toy train operation is designed to give a maximum voltage of 25 volts. The transformer is connected by the wire II with one of the wheel bearing rails l2 of a toy railroad track. The other side of the transformer is connected with the third rail it through the controller C and wires indicated at M and l5.
The structures diagrammaticaly illustrated at the right of the railroad track are those carried on the locomotive or train. The current is picked up by the usual current collector l9 bearing on the third rail and returned through the axles I9". A' load, indicated at L, may include lamps on the cars or locomotive indicated at 20, and a propulsion motor 2| whose field and armature are interconnected with the supply line by a reversing switch 22. This reversing switch is electromagnetically operated and is preferably of the type which operates to stop the propulsion motor or reverse its direction of rotation when the manual train controlling switch ii! is manipulated. This type of reversing switch does not affect the train lights. It is in common use in this art.
The train also carries a relay 23 of the type shown in Bonanno Patent 2,155,343 granted April 18, 1939. It is constructed so that the maximum alternating current voltage available will not operate the relay so as to close the contact indicated at 24. The contact 24 is in series with an accessory 25 such as a motor with field and armature adapted to operate the blower of an air whistle.
The controller C employs an inverted box-like body 38 of insulating material. The body is provided with binding posts 31 and 32 as indicated. The binding post 3| has a screw 33 which passes through one of the elements 34 of a rectifier R. The other element 35 of the rectifier is secured to the element 34 by a suitable insulated rivet indicated at 36. This rivet passes through a sheet metal connecting strap 37. A resistance coil 38 is wound about the support 3 of rectifier element 34 and insulated from it by a strip of paper or other insulating material, indicated at 39. One end of this resistance coil is connected under the head of the binding post screw 33. The other end of the resistance coil is connected by a wire 8 with a contact strip M.
The body member 30 has downwardly extending elements 42, 43 and 44 which form a rectangular receptacle for the core 45 of a choke coil 483, thewinding being indicated at i7. One end of this winding is connected by a wire 48 with the binding post 33 and the other end is connected by a wire 39 with a contact 59.
The insulating body 30 has a downwardly extending square post 5| which receives the straps or contacts 31, M and 50 above referred to, and also an upper contact strip 52 and comparatively stiff spring member 53 all of which have square holes to fit the square post. They are separated by insulators m and held in place by a screw 52a. This type of assembly of contacts for circuit controllers is covered by copending application of Joseph L. Bonanno, Serial No. 324,2 l6 filed March 16, 1940, executed concurrently herewith.
The spring member 53 extends laterally, as indicated at 54 and 55. The ends are bifurcated to receive insulating push buttons 56 and 51.
The upper contact 52 is connected to the screw 58 of the binding post 32 by a Wire indicated at 59. The right-hand extension 54 of the spring member 53 has a contact 60 adapted to normally be held against the contact 6| on the end of the conductor strip 52 so that when the button 51 is not depressed the power rail I3 is always connected with the conducting strip 53. Depressing button 5'! opens the circuit. The left end of this conducting strip has an upwardly extending contact 62 opposite the contact 63 at the end of conducting strip 50, so that when the button 56 is in normal position connection is always made through the coil 4'! of the choke. When the button 56 is pushed down the spring nature of the conducting strip 56 causes the contact 63 to follow the contact 62 during the early part of the movement of the contact 62. This conducting relation continues until the lower contact 64 carried by the spring 53 is brought against the contact 65 carried on the spring 31. At this time the rectifier R will be in shunt with the choke coil. Further downward movement of the button 56 will carry the contact 62 away from the contact 63 and will immediately thereafter bring the contact 65 on conductor spring 31 against contact 66 on conducting spring 4|, thereby introducing the resistance 38 in circuit in shunt with the rectifier. The purpose of introducing the rectifier momentarily Without protective shunt or resistance is to generate enough direct current to close the relay even when the load may consist of only the relay coil. This may occur when the train is standing still and there are no lamps or other current consuming devices in the circuit. During the downward movement of button 62 it will be seen that the circuit to the load has not opened and one has been able to pass from the condition where a choke was in circuit to a position where a rectifier shunted by a resistance is substituted. The impedance of the choke coil and the joint resistance of the resistance coil and rectifier are selected so that there will be substantially the' same voltage available on the track circuit, irrespective of the change in the loading brought about by a change from alternating current to alternating current with a direct current component so that the lights, propulsion motor and other accessories have practically the same efiective voltage for operation. During the very short interval of time while the rectifier alone is in circuit enough current will flow to keep the reversing unit on the locomotive from operating. The time is too short to cause a noticeable slowing down of the train or dimgming of the lights.-
The bottom plate is secured to the insulating body by screws ll threaded into holes indicated at 12. This plate has upwardly extending springs 13 adapted to press against the field of the choke coil and hold it in place.
It is obvious that the invention may be embodied in many forms and constructions within the scope of the claims and I Wish it to be understood that the particular form shown is but one of the many forms. Various modifications and changes being possible, I do not otherwise limit myself in any way with respect thereto.
