Bonanno, Madison, N. .L, assignor to The Lionel Corporation, New York, N. Y., a corporation of New York Application July 26, 1949, Serial No. 106,859
The present invention relates to toy train controllers, and is more particularly directed toward controllers for use with toy railroad systems on which a single train is operated at one time, this train being of the type which is normally equipped with remote-controlled automatic reversing mechanism and also carries a remote control accessory, such as a whistle, to be operated at will irrespective of whether the train is running forward, backward, or is stopped.
In my prior Patents 2,155,343, of August 18, 1939, and 2,316,551, of April 13, 1943, I have shown and described toy train controllers for the same general purpose as the present controller, and the present invention is more particularly directed toward improvements relating to the structural inter-relations of the various parts entering the electric circuits of such controllers, whereby they may be economically manufactured, assembled, inspected, and tested.
The invention also contemplates structures in which the electrical parts for the aforesaid purposes are so asem'bled as to provide a rugged structure unlikely to be damaged or get out of order when in use.
A further object of the invention is to provide a structure for the above purposes having an ornamental, protective cover of shock resistant plastic which can be detached at will to permit inspection of the electrical parts.
Other and further objects will appear as the description proceeds,
The accompanying drawings show, for purposes of illustrating the present invention, one of the many embodiments in which the invention may take form, it being understood that the drawings are illustrative of the invention rather than limiting the same.
In the drawings:

Fig. 3 is a top plan view of the controller with the control handles and cover removed;
Fig. 4 is a longitudinal section on the broken line 4-4 of Figs. 2 and 3;
Fig. 5 is a transverse section on the line 5--5 of Figs. 3 and 4;
Fig. 6 is an inverted plan view of the contact bearing plate assembly;
Fig. 'l'is a wiring diagram; and
Figs. 7a, 7b, 7c and" 7d are fragmentary views illustrating different positions of the movable contactor.
In the drawings, the laminated field of the transformer is shown at II]. It is of the usual form and carries a primary winding I I and a secondary winding in three parts numbered I2, I3 and I4 (see Fig. '7). The part I2 of the secondary winding is wound so as to be carried about a coil form I5, and has a bared, exposed upper face I6, one end of the coil being connected to a lead or tap I2, the other end to a terminal I2 carried by the form I5. The other coils I3 and I4 have taps or leads I3, I3", and I4, I4", respectively, as indicated in the wiring diagram (Fig. '7). The primary winding I I is connected to soldering lugs l1, l1 carried by the form I5, and these lugs are connected to a two-conductor current supply cord as indicated at I8,
The coil core assembly I9 is secured by means of rivets 20 to a bottom plate 2I having a depressed central portion 22 (as shown in Fig. 5) to accommodate the coils, and to an upper top bracket or plate 23 having side members 24, 24 extending upwardly above the level of the exposed coil winding I6. The members 24, 24 are bent laterally as indicated at 25, 25, and downwardly as indicated at 26, 26, and are provided with openings at 21, 21. The corners of the top bracket have threaded openings at 28, and upwardly bent anchorage lugs 29. The bottom plate 2I is welded at 30 to a sub-base 3|.
The coil-core assembly with lead wires, upper bracket, lower plate, and sub-base form a preassembled unit.
The second pre-assembled unit employed in the complete toy train controller carries all the parts on a flat insulating plate 40. The right-hand side of the plate has an opening M and a concentric arc-shaped slot 42. A shaft .43, splined as indicated at 43, has a reduced portion 44 extending through the opening M and a stop lug 45 extending into the slot 42. The lower end of the shaft 43 passes through a conductor strip 45 and a spring contact arm 41. These parts are secured in place by a washer 48, the lower end of the shaft being upset as indicated at 49. The strip 46 extends to the right, as indicated at 50, to form a soldering lug, and its left end carries a contact 5| which extends up through a hole punched in the plate 40. The left end of the plate 40 is provided with an opening 52 and two are arc-shaped slots 54, 55. The opening 52 receives a shaft 56 (splined as indicated at 56) having a flange 51 provided with two laterally extending arms 58, 59. The flange carries a yieldable multiple arm conholes 9| for the binding posts.
tactor having two outwardly extending contact arms 6! and 62. The lower end of the shaft 56 receives a spring 63 having upwardly bent ends 84, which extend through the slots 54 and 55 and up past the sides of the arm 59. The upper end of the spring 63 bears on a contact strip 66, and it is held in place on the shaft by a ring 67. The spring 63 urges the shaft downwardly to bring projections 51' against the top of the plate, and holds the contacts 6| and 62 against the upper face of the plate or against the contacts which protrude through the plate, and the ends 64, 65 of the spring bias the shaft 56 to the orientation shown in Figs. 3, 4, 5, 6, '7. The slots 54 and 55 are the proper length to limit the swing or throw imparted to the shaft 58.
The insulating plate 40 carries a contact 68 connected to a soldering lug 69, the contact 68 being in the path of the right arm 6! of the'contactor so as to be engaged by it after it moves away from the contact 5|, as shown more clearly in Figs. 7c and 7d. The plate 45} also carries a'contact 70 with a wide face. This contact is in position to be engaged by the left arm 62 of the contactor 60 before the right arm leaves the contact 5! as shown more clearly in Fig. 7b. The extreme left end of the plate 40 carries a downwardly extending rectifier bracket H held in place by a rivet 12 and a projection 13 enter- The 5'," bracket H carries a pin '15 on which is mounted ing a hole 14 in the insulating plate 40.
a spacer T6, a conducting strap 71, a washer l8, and a rectifier disc 19. The Strap I1 is secured to contact 10. The lower end of the bracket H has a soldering lug 8D, and a resistance wire 8: is soldered to this lug, wound about an asbestos insulator 82, and connected to a wire 83 which in turn is connected to the soldering lug 69.
The rear edge of the insulating plate 40 Q carries four binding posts which, read from left to right, are marked U, A, B, and C, respec-- tively. The binding post U is directly connected with the strap 66; the binding post A carries a soldering lug 84; the binding post B carries a soldering lug 85; while the binding post C carries a soldering lug 3 6. Lug 85 also extends forwardly as indicated at '85, and supports a circuit breaker 8'1. This circuit breaker is of the bimetallic, thermally operated, overload type and has a soldering lugBT.
The insulating plate 40 is provided with four holes 88 to receive the upwardly extendingdugs 29 carried by the top bracket 23. These lugs may be twisted slightly, as indicated in Fig. 3, to lock the insulating plate in position.
The soldering lug 50 is connected to the lead M from the coil [4, the soldering lug 84 with the lead [3" from the coil l3, the lug 81 on the circuit breaker to the lead l2 from thecoil 12, the lug 86 on post C to the terminal-l2 of the coil i2 (by wire 86'), and the soldering lug 12 on the rectifier bracket with the lead 14" from the coil l4. These operations complete the assembly of the electrical parts of the transformer and controller.
An inverted cup-shaped molded plastic cover 93 is apertured as indicated at 9|, 9! to pass down over the shafts 43 and 56. It also has This cover extends down past the coil core assembly and the bottom plate 2!, so as to completely enclose all the electrical parts. The corner portions of the bottom plate 2! are cut away as indicated at "2 to accommodate the corner portions 92 4 of the cover, so that the cover and bottom plate fit closely and the bottom edges of the cover are held against lateral movement. The top of the cover is provided with four holes indicated at 93 for screws 94 which enter holes 28 to secure the cover in place. It is thus apparent that the entire assembly of the electrical parts and the testing of the same may be accomplished when the cover is off, and the cover may be readily taken off at any time when it is desired to inspect the interior.
The shafts 43 and 56 carry operating handles 95 and 96 fitting the splines on the shafts. The handle 96 has a projection 97 entering an arcuate recess 98 in the cover, and th handle 95 has a similar projection (not shown) entering recess 99 in the cover. These insure the proper orientation of the handles.
The controller is adapted to be used with toy train equipment carrying cars and reversible locomotive with ste'p-by-step reverse mecha nism and whistle in the same manner as shown in my prior Patent 2,155,343. 'In the drawings, Fig. '7, the wheel bearing rails of such track are illustrated at I60, I00, and the power rail at IOI. Thebinding post U of the controlleris connectedby a wire [02 with the wheel bearing rails, and the power rail is connected by a wire I03 with either the binding post B or the binding post A, the latter giving a'higher output voltage than B. A truck on the locomotive is indicated at it'd. The propulsion motor of the locomotive is indicated at I05. It has a field winding I06 permanently connected to the current collector bearing on the power rail, and an armature connected to the locomotive frame through a reversing switch I97. This reversing switch is operated by a ratchet and'pawl [98 under the control of an indexing 'coil 109 adapted to step the reversing switch once for each impulseof current received, so as'to open the circuit,then reclose the circuit with reverse connections through the armature. A permanent lamp or other load in the locomotive or train is indicated at H0. The coil of a relay'is indicated at HI and its armature at I I2, this relay being of the type discussed in my Patent 2,155,343.
bf power and to the track asindic'ated, train operation may be carried on by manipulating the handles "95 and 96. When the handle "95 is in the extreme counter clockwise position, the contact arm 41 is off the exposed fac'eofthe coil and the circuit to the track is 'op'ened. The locomotive is started and the speed controlled by the manipulation of handle 95. The path of the current'may be traced fromth'e contact arm 47, strap '46, contact 5l, 'contactor'fie, :strap 6'5, to binding post'U, and from the power-rail through wire I03, binding post B, strap '85, circuit breaker 81, wire '81 to the'coil l2.
If theop'erator desires'to sto'p the'locomotive, the handleSG canbe s'hiftedto'mOve the'con tacts from the position shown-in Fig. 7 to the position shown in'Fig.'7a. This'opens the circuit to the track, thus de-energizing the rlay 1&9. Release of the'handle 96 allows thecon- -mechanism one step, which keeps the propulnipulation of the handle 91 will operate the indexing mechanism again and start the locomotive in the other direction. I
If, on the other hand, the operator desires to blow the whistle, the handle 96 is turned in a clockwise direction, shifting the parts in the position shown in Fig. 7 through the intermediate steps shown in Figs. 7b, 7c and 7d. This operation does not open the circuit to the track, but it introduces the rectifier into the circuit so as to supply a small component of direct current to the propulsion circuit. This small direct current component is effective to actuate the relay H2 and connect the motor H3 in the circuit so that the whistle blows as long as the handle 96 is in this position. Releasing the handle 96 permits the spring 63 to restore the parts to normal position. A fixed potential is available between the binding posts B and C for low voltage accessories, such as switches, lamps, etc.
Since it is obvious that the invention may be embodied in other forms and constructions within the scope of the claims, I wish it to be understood that the particular form shown is but one of these forms, and various modifications and changes being possible, I do not otherwise limit myself in any way with respect thereto.
