Application filed May .29, 1930. Serial No. 457,461.
The present invention, in its broadest aspect, relates to motor-control systems, and especially to toy motor-control systems. More particularly, thisinvention relates to such systems of controls as are employed'in connection with toy locomotives, toy fire engines, and the .like, for operation on a trackway. g r A primary object of the invention is to provide -a novel motor-control system adapted'to control a plurality of motors in a predetermined'order to automatically effeot'the operation of a plurality of devices in a prearranged manner and in a predetermined order. 7
Another object of this invention .is to provide. a motor-control system' of the above-described character which shall include a plurality of control switches includ- -ing electrically controlled thermostats and the aforementioned devices.
, More specifically, it is among the objects of the present invention to providea novel electrical toy fire apparatus which shall be adapted to be propelled along a guiding means including a pair of spaced insulated sections; to provide automatic means adapted, at predetermined intervals, to propel the apparatus from one insulated section to another; to rovide means for insuring the stopping o the apparatus at each of I said sections, to provide ahose and ladder on the apparatus and means for automatically causing said ladder to be raised and water to be pumped and discharged in a continuous streamfrom said hose only while the apparatus is ,situated at one of said insulated sections; to provide means in suring that the ladder shall be'loweredand the hose discharge ended before the apparatus is able to move away from the said insulated section; and to provide means whereby-the raising and lowering of the ladder controls the access of the hose end to the water source.
With the above andother objects inview which 'will more readily appear as the nature of the invention is better understood, the same consists in the novel construction,
make-and-break contacts carried by one of combination and arrangement of parts hereinafter more fully described, illustrated and claimed.
An illustrative and preferred embodiment trolled hose-end raisingand lowering device;
Fig. 3 is a combined plan view of the trackway and diagrammatic views of the effective wiring systems at each of the insulated back sections; and
Fig. 4 is an enlarged diagrammatic view of one of the insulated back sections shown in Fig. 3, and hereinafter referred to as the operating sector. In this view the cir; cuits and circuit controlling means on the toy app'artus are also diagrammatically illustrated. 1
Similar reference characters designate corresponding parts throughout the several figures of the drawings.
Referring'to the drawings, and more particularly to the showing of the toy fire a paratus per se as shown inFig. 1, it will e seen that this may comprise primarily a driving or tractor member 10 and a driven.
or trailer member 11, mounted respectively upon tractor wheels 12 and trailer wheels 13. Thewheels 12 and 13 are adapted to be mounted upon the rails 14 of a continuous trackway. w
The tractor member lOmay'carry a trac tor motor 15 of any desirable or suitable type for driving the tractor wheels 12. The tractor motor 15 is shown as adapted toreceive its power from the live third rail 16 through collector shoe or roller. 17 riding on the said third rail. Mounted at the forward end of the tractor member 10 may be, a solenoid operated brake 18. Also mounted within and supported by the trac-v tor 10 may be the thermostatic switch 19. Depending from one of the fenders of the tractor in a manner to enable them to coact with an extraor fourth rail (described in detail hereinafter) are two mutually insulated collectors, which may take the form of contact rollers 20 and 21. Extending around and beyond the forward end of the tractor is the guard rail 22.
Referring now more specifically to the trailer 11, this may be coupled to the traclarged portions and correspondingly shaped are a pair of arcuate brass contact members 28 and 29. Adjacent the upper end of brass contact 28, the latter merges into an insulated non-conducting portion 30. .A similarnon-conducting portion 31 is disposed adjacent the lower end of the other brass contact 29'.
Pivotally mounted at its lowermost end between the uprights 26 and 27 is the'ladder 32. Depending from the opposite sides of the ladder, and connected together by the metallic rod 33, which is disposed a slight distance above the point of support of the ladder, are a pair of brass brushes 34 and 35. As shown, the brush 34 is adapted to slide along the brass contact 28 on the upright 26, while the brush 35 is adapted to similarly cooperate with the brass contact 29 on the upright 27. The rod 33 is loosely mounted on the ladder, and extendin from the middle thereof may be a lug 36.v pring means 37, extending from said lug to the lowermost rung of the ladder 32, may be provided. In this way, a positive slidable connection between the brass brushes 34 and 35 and the contact devices disposed on uprights 26 and 27, is assured.
Depending from the lowermost end of one side of the ladder 32 is a flexible brasscontact 38 which is adapted to cooperate with another contact 39 disposed on the upright 26 as shown. Extending laterally from the upright 27 may be a ledge or block 40 adapted to loosely support the depressible brass contact 41. A spring 42 is interposed between the block 40 and an enlargement on the upper end of depressible contact 4l. Upon the corresponding side of the ladder 32 and. situated at a point on the ladder whereby it is adapted to contact with the contact 41, is another brass contact 43.
From the above-described arrangement of contacts, it will be seen that when the ladder is in its lowermost position contacts 41 and 43 will be closed, and contact 35 will rest on the non-conducting portion 31. When the ladder is in its uppermost position, contacts 38 and 39 will be closed, and contact 34 will rest on the non-conducting portion 30.
Means for raising and lowering the ladder is preferably provided adjacent the uprights 26 and 27 in the form of any desirable motor 44. This motor may be operatively connected to the lower end of the ladder by any conventional train of reduction gearing 45 for slowly rotating'a crank arm (not shown) to reciprocate a pitman. or lever 46, pivotally connected to the lower end of the ladder. On outward or inward movement of the pitman, the ladder is swung about its pivotal mounting in the apparatus, to effect the raising and lowering of the ladder 32.
Carried by the ladder, and terminating in a nozzle adjacent the upper end thereof, may be a section 47 of hose. The other end of the hose 47 is connected to one side of the pump 48. Another section 49 of hose extends from the other side of the pump, and is adapted to be supported along one side of the chassis. Means (described in detail hereinafter) is provided for raising and lowering the free end of hose section 49 relative to a water-containing trough 50, which may depend from'the chassis 25 in any suitable manner, or may be disposed adjacent the trackway, as shown in Fig. 1.
A/pumpbperating motor 51 is preferably mounted adjacent the rear'end of the chassis 25, and the pump 48 may be driven from said motor through the medium of any conventional system of gears and levers, such as shown, for example, at 52. I
Coming now to the means adapted to effect the raising and lowering of the free end of hose section 49, it will be seen, by reference to Figs. 1 and-2, that this may consist of a post 53 extending upwardl from the chassis 25 adjacent the rear end t ereof. Pivotally secured to the post 53 in a manner to form a pair of arms of unequal length, is the lever 54. Depending from the end of the longer arm is the hook-ended rod 55, in the hook end of which the free end of hose section 49 is lodged. Ext-ending upwardly from the end of the shorter arm of lever 54 is the operating rod 56. A relatively light transverse or T'-forming member 57 suitably attached to the upper end of rod 56. Guiding. means, which may assume the form of the right-angled bar 58 extending upwardly from the chassis 25, may-be provided for the rod 56. In the embodiment shown, the rod 56 reciprocates through an opening in the upper bent-over end of the bar 58. The combined height of the members 56 and 57 is so regulated that when the is adapted to rest upon and depress the transverse member 57 and maintain the lever 52in substantially horizontal position. The length of the rod 55 is regulated ,so that when the lever 54 is substantially horizontal the hose end is raised from the trough 30. It is'thus seen that when the ladder is b o the free end of the hose section 49 is supported above the surface of the water j in the trough 50. As soon, however, as the ladder is caused to be raised olf the cross member 57, theweightof hose end 49 causes therod 53 to drop, lowering the hose end into the trough.-
Strap means 58 or the like may be provided for securely holding the nozzle end of the hose section 47 in place on the ladder.
A double throw thermostatic switch 59 may be enclosed within the box-like contain er 60 situated upon the chassis at any convenient place thereon. Y
As shown in Figure 1, a second guard rail 61 may be disposed around the trailer member 11.
" Referring now moreparticularly to Fig.
3, this shows the preferred railway track systom upon which the hereinbefore described apparatus is adapted to ride. As has already been pointed out, the track system' comprises a pair of main rails 14, adapted to be attached in properly spaced relation to each other and in suitable lengths by means of conventional cross ties 62. -A live third or powerrail 16 extends between the in standard sections which may be joined together by any conventional-meansi'such as the well known pin and socket connection.
. Power is supplied to the live rail by means of conductor wires 63 from any suitable source 64.
. fire-house 65 (Fig. 3) is located, asection 66 of the live third rail 16 is insulated from the remainder thereof inanyconventionalway, as by replacing the usual metallic pins by fibre ins, diagrammatically illustrated at 67. T e section 66 may well be termed -the fire-house sector. The fire-house 65 is' adapted to house the entire fire apparatus,
[16 by conductor wire 75.
Referring to the wiring of the :fire apparatus as shown in the diagram illustrated in Figs. 3 anii 4, it will be seen that the contact shoe or roller 17 is connected to one side of the tractor motor 15, the other side of the motor being connected to one of the terminals of the solenoid 76 of the brake 18. The other solenoid terminal may be grounded through the tractor body 10 and wheel 12, as shown. From the first-mentioned side of the motor 15, a conductor wire 77 also extends to the depressible contact 41 carried on the upright 27.
, Collector or contact shoe 20 is electrically, connected to one terminal of thermostatic switch 19, and the. other terminal is conthermostatic switch 59, from which the conductor 79 extends to one side of the pumpmotor 51.

Contact 39 on unpright 26 may be grounded through conductor 81 to chassis 25' and wheel 13,-as shown. The other two terminals of thermostat 59 are respectively connected to contacts 28 and 29 by conductors 82 and 83.

The thermostatic switches 19 and 69 are similar in construction and. operation, and a description of one will serve for' both.
The switch 19 (see Fig. 4) com rises a flex- -ure member 86 havin a hig resistance winding87. and an out at terminal 88'normally out of contact with the free end ofthe flexur'e member 86 and electrically connected and is preferably provided with spring.
hinged swinging front and rear doors 68.;
Disposed adjacent the fire-house sector is'a thermostatic switch 69. QCOnd-uctor'wires 70 and 71 respectively connect the thermosulated by-fibre pins 73 fromthe remainder thereo'f, as above described in connection with the. fire-house sector. Thissect'ion may "65 be termed the operating sector. Adjacent.
87. The oppositeend of the winding.
and corresponding end of the fiexure memiio "to one end of the high resistance 8 .ber, 86 are -electrically connected by conductor 89"tocontact shoe 20.
The thermostatic switch 59 is of like canstructionand operation, it being noted, however, that two relatively spaced outlet -terminals 90 and 91 are employed, terminal 90 being normally-in contact with the free end of the flexure member.
The operation of the deviceis as follows:
- H li that the tracks are connected,
substantially as shown in Fig. 3, and a source of current connected thereto as shown, the apparatus is placed on the track in the firehouse 65 and on the insulated fire-house sector 66. The circuit is then completed between the insulated third rail section 66 and ground rails 14 through the thermostatically-controlled circuit which bridges rails 66 and 16 on opposite sides of insulated pin 6 9 Due to the resistance in the circuits imposed by the winding of the thermostatic switch 69 the apparatus remains stationary on this track sector until the flexure member of the thermostatic switch 69 is heated sufiiciently by the winding to cause it to warp and make contact with the outlet terminal, bridging out the winding and permitting full current to pass to the sector 66 and tractor motor 15. The brake operating solenoid 76, being connected in series with the tractor motor, is energized upon passage of current to the motor releasing the motor brake 18 and the apparatus'is propelled out of the sector 66.
The spring-hinged doors 68 of the firehouse 65 are pushed open by the guard rail 22 which extends around the front of the apparatus, and the doors close again after the apparatus has passed by. The doors are kept clear of the main body of the device by the guard rails 22 and 61, thus preventing dislodgment by the doors of any object which may be carried along the sides of the apparatus, such as removable ladders, etc.
The fire apparatus travels along the trackway until the insulated operating sector 72 is reached. As soon as the collector shoe 17 rides from the live rail 16 onto the section 72, the supply of current to the motor 15 and motor brake solenoid 76 is cut off. Operation of the motor ceases as the brake 18 is' applied to positively stop the apparatus within the limits of the sector 72'. As the shoe 17 rides onto this insulated sector, the mutually insulated collector or contact shoes 20 and 21"c0meinto contact with the live extra or fourth rail 74.
Upon contact of the shoe 21 with the extra live rail 74, the ladder 32 being down as shown in Figs. 1 and 3, current passes from conductor 79 through the flexure member of thermostatic switch 59, outlet terminal 90 and conductor 82 to the arcuate contact 28 on the ladder supporting upright 26, hence through brush 34, rod-33 and conductor 84 to the field side of the ladder-opcrating motor 44.
of gears and levers heretofore described, the
brush 35, which is also electrically connected to the rod 33, leaves the insulated The motor starts,.and through the system p0rtion'3 1 and slides onto the brass contact 29 on upright 27. When the ladder reaches its uppermost position the brush 34 slides onto the insulated portion 30, breaking the circuit through conductor 82 and causing the ladder-operating motor 44 to stop. It will be noted that brush 35 now rests on the arcuate contact 29, completing the circuit to the motor 44 through the high resistant winding on the flexure member of the thermostatic switch 59. Due to the resistance now imposed in'the circuit, the motor 44 remains idle while the ladder is in elevated position, for approximately 60 seconds, during which time the winding of the thermostatic switch 59 heats up, causing the flexure member to warp and make contact with outlet terminal 91, bridging out the winding and permitting full current to pass by conductor 83 to the arcuate contact 29, henceto the ladder-operating motor 44. The motor is again started and throu h the system of levers and gears returns t e ladder to normal or horizontal position. When the ladder reaches its lowermost position, the motor is again stopped as the brush 35 leaves the contact 29 and slides onto the insulated portion 31.
It will be noted that during the interval of time the ladder is raised, contacts 41 and 43 in the tractor motor-operatin circuit are broken, preventing passage of current to the motor 15 from the live rail 74 through contact '20, thermostatic switch 19 and conductors 77 and 78.
As the ladder reaches its uppermost position, flexible contact 38, mounted on the lower end of the ladder, makes contact with the terminal 39 on the ladder supporting upright 26, completing the circuit from conductor 79 through water pump motor 51 to the ground. The water pump motor 51 is The hose nozzle may be adjusted by the securing means 58 on the free end of the ladder to throw the stream of liquid into a suitable receptacle (notv shown) or wherever desired. When the ladder is again lowered to its horizontal position, it actuates the hose-end raising device, and the hose end is again lifted out of the water trough. During the time that motors 44 and 51' have been operating, the tractor motor 15 has been idle, because the collector 17 has been resting on the insulated sector72 and the circuit from contactshoe has been 7 broken,
,up, causing the flexure bar 86 to warp and short the bar and outlet terminal 88, permitting full current to flow through to the brake solenoid-and motor -15. -'The brake is thus-released and the motor started, propelling the toy apparatus away from the operating sector 72 and back to the fire house'or to another operating sector. Al-
though but one operating sector is described,
it is obvious that as many of these may be provided as' is desired,
The terminals of the thermostat 19 rev main shorted until the apparatus has traveled away from the operating sector 72 and the collector 17 again makes contact with the live third rail 16. At this instant -.the circuit through the t ermostatic switch 19 is broken as the collectorQO runs 0E and leaves the fourth rail 74;
From the foregoing detailed description and from the accompanyin drawings, the construction, operation, an advantages of the improved electrical toy fire apparatus will be readily apparent.

it will be understood'that various modifications may be made-therein, both as to de-,
