In the present form of construction as shown in detail in the drawings the outfit from which one can assemble either a toy locomotive or a toy power plant is shown as consisting of a number of distinct parts. These parts may be generally described as including the following. A side plate A, a combined controller and brush rigging assembly B, a motor armature unit C, a second side plate D, a motor field assembly E, a pair of reduction gears F, F, a gear cover plate G, a pair of locomotive trucks H, H having driving wheels and axles, a bottom plate I, provided with contact rollers, a first speed reduction power shaft and assembly J, a second speed reduction power shaft and assembly K, a power plant base L, and nine screws.

In making up the toy locomotive, the parts J, K and L are not employed, while in making up the toy power plant the parts H and I are not employed.

The side plate A may be a fiat smooth steel plate provided with holes, slots and projections such as indicated in the drawing. These special parts will be enumerated as the description proceeds.

The combined controller and brush rigging assembly B which is shown in detail in Fig ures 1, 2, 4t and 7 includes a rectangular insulating plate 20 which carries all these parts. This insulating plate carries two connecting straps 21 and 22 the former being the lead in connection for the controller as indicated more clearly in Figure The lower end of this strap has an outwardly extending foot 23 for a purpose to be pointed out later. The upper end of the insulating plate 20 carries a reversing switch and controller for the motor. This reversing switch includes a pivotally mounted operating lever 25 which is mounted about a center 26. It carries contacts 27 and 28 indicated in dotted lines in Figure 3. These contacts are cooperative with four posts 29, 30, 31 and 32. The post 29 is connected at the upper end of the lead in strap 21 while the post 30 is connected at the upper end of the brush lead strap 22 and the post 32 is connected to the other brush lead strap 33. The post 31 connects with a contact button 3 1 fixedly carried by the insulating plate.

The contact strips 22 and 33 each carry a brush rigging as indicated at 35. On mak ing up this brush rigging the lower ends of the straps 22 and 33 are rolled as indicated at 36 to provide a round passageway or holder for a brush 37. Each of these brushes is carried on the end of a spring 38 which urges it inwardly toward the commutator of the motor. Each of the brush riggings is provided with a brush lifter in: the form of a lever 39 pivoted about the screwlO and havinga freeend 4:1 engageable with the spring 38 to lift the brush.

The insulating plate. 20 and the metal plate A are provided with pairs of aligned holes and 43 to receive screws 42 and 43 for fastening these two parts together. To facilitate aligning these two parts, the insulating plate 20 carries pins 44 which pass into holes 44 in the metal plate and the imeta'lplate carries a bushing l5 for the armature shaft, which bushing passes through a hole 45 in the insulating plate. The plate A is also provided with cut-outs as irdicated at 46 and 47 which accommodate the prongs 48 used in fastening the conducting strips on the insulating plate 20. The slot or cut out 46 also permits passing the controller handle through the slot as indicated inFigure 2.

The assembly of these two parts is accomplished as indicated in Figure 2 in a very simple manner, it being merely necessary to pass the handle of the controller through the slot, and swinging the parts into position so that the oins 14 pass through the holes 14K and the bushing 45 passes through the hole 45. The screws 42 and 13 may then be inserted in place and this part of the assembly is completed, as shown in Figures 3 and The commutator assembly C may, as here shown, include an armature shaft 50, armature field structure 51, armature windings 52, spur driving gear 53 andconnnutator 541-. These parts are provided as an assembled unit and may be inserted into the motor assembly as indicatedin Figure 4. To accompany this operation it is merely necessary to press the tips 39 of the brush lifting fingers toward one another and pass the shaft through the bushing 4.5. Thisbrings the parts to the assembled condition as illustrated in Figure 7.

The plate D resembles in general the plate A but it is intended for carrying the field structln'e B. As appears in Figures 1 and 5 the plate D provided with four small holes 60, and with two short spacers 61 riveted to it and provided with tapped holes 62. The motor field assembly D ismade up to have the usual laminated field structure 63 and field windings 64. This field structure is held together by rivets indicated at 65 and having reduced end portions 66 cooperative with the holes 60 in the frame plate D. The field structure is also provided with screw receiving holes 67 through which screws 68 may be passed to thread them into the tapped holes 62 in the bosses 61 carried by the frame plate. In this manner the field structure and plate may be brought together to place the parts in position as shown in Figure 6.

One end of the field winding is grounded by soldering it to a rivet, as indicated at 64.

The other end 64 is connected to a strap 70 fixedly mounted in the :i'nsulating spool ends 640; \and 64b. Thestra-p 70 carries a spring pressed plunger 69 which projects outwardly as indicated in Figure 6. It is then in :a position to come opposite the contact 34 carried on the controller assembly.

Theplate D as here shown also carries three spacers orzposts 71, 72 and 73preferablyrivetedto .it and provided with reduced end portions cooperative with holes 7 1, 75, and 76 in the plate A. The parts shown in Figures 6 and 7 may be brought together by merely moving them toward one another in the positions there indicated so as to bring the reduced ends of these spacers through the corresponding-holes after which screws 77 may be passed into the threaded holes 71-, 72 and 7 3' in the spacers to clamp the plates and supportingparts together. lVhen the parts have been assembled to this extent the alnnature shaft 50 and pinion 53 project out through a hole 78 in the frame plate D.

The outside of the frame plate D is provided with two posts 7 9 shown in Figure 8, adapted to receive the reducing gears F which may be assembled so that the parts will appear-as shown in Figure 9. These two gears are each in mesh with the pinion 53. The plate D is also provided with two posts or lugs SOnhaVi-ng reduced end portions and threaded holes. The cover plate Gr above referred to is adapted to fit over the parts as indicated in Figure 10. This cover plate has small holes 81 to receive the studs 79, has abearing hole 82 for the armature shaft 50 and is provided with two holes to permit passing screws 88 into the supporting studs 80. All the foregoing parts may be assembled in the manner indicated, and the device in this stage of assembly is in condition for further assembly to make it into a toy locomotive power plant or a "toy unit for general purposes.

Assuming that it is to be assembled into a toy locomotive power plant, the operations will be described. During these operations one employs the two truck units H and the current collector or bottom plate I. As shown in Figure 1 these truck units each have a shaft 89 fixedly carrying a driving gear 90 and a pair of track wheels 91. The shafts, 89 also loosely carry bushings 92 having undercut portions 93 as indicated. The buslr ings are held in place by prick marks 89.

The frame plates A and D are provided with slots 94, 95, 96 and 97. These slots arearranged to be opposite one another in pairs when the frame plates and motor parts are assembled as shown in Figure 10. These slots provideguide ways to receivethe bearing members 92, and the next'step in assembling the locomotive powerplant is to place these two axles and associated parts in position-byx-merely sliding the bushings down the ice slots thereby bringing the gears into mesh with the reducing gears F.

The current collector plate or bottom plate I as shown in Figures 1, 11, 12 and 13, is adapted to be fastened in place after the running gear has been installed.

This bottom plate and contact carrier consist essentially of a sheet metal stamping which fits the motor frame, and a pair of rail contacting rollers 101 and 102 insulatively supported from the stamping 100 and adapted to ride on the third rail of the toy railroad track on which the locomotive is to be used. To insulatively support the rollers a strip of insulating material 103 is secured to the stamping 100. As here shown the method of securing these parts together includes a plurality of prongs 104 bent over onto the strip of insulation and a pair of a-pertured prongs 105 adaptedto receive the reduced end portions 106 of the insulating strip. This insulating strip carries a flexible metal strip 107 on the ends of which are mounted saddle pieces 108 which extend down 7 through holes 109 in the stamping 100 so as to carry the rollers 101 and 102 spaced below the body of the stamping 100. The resilient roller supporting strip 107 is held in place on the insulating strip 103 by a stamping 110 and prongs 111, which are folded over the metal strip 107 and underneath the insulating strip 103, the stamping 100 being cut away as indicated at 112 in section in Figure 13 to keep the prongs 111 out of contact with the stamping. The contact carrier 107 is prevented from twisting out of place by the roller supporting saddles 108 which pass down alongside the fixedly carried insulating strip 103. The stamping 110 carries a spring pressed plunger 113 for a purpose to be described.

T he stamping 100 is shaped so as to securely fit the motor parts heretofore assembled and is arranged that it cannot be improperly placed in position on the same. The stamping has upwardly bent end members 114 and 115 slotted as indicated at 116 and adapted to pass outside the posts 71 and 72. The sides of the stamping 100 are provided with four upwardly extending projections 117 adapted to fit outside the frame plates A and B and to engage with the bushings 92 on the shafts of the running gear. The plate A is provided with projections 118 adapted to pass through slots 119 in the stamping 100 thereby preventing assembling these parts improperly.

To complete the assembly of the locomotive motor the bottom plate 100 and parts carried thereby is inserted in place, which may be accomplished by merely lowering it from the position shown in Figure 11 onto the structure as indicated in Figure 10. This permits the slots 116 to pass by the shanks of thumb screws 120 carried by the spacers 71 'toy locomotive will have been assembled utilizing the parts designated as A, B, C,

,D, E, F, G, H, I and the nine screws provided in the outfit. It will be noted that it is unnecessary to connect or disconnect any wires whatever in assembling the motor. All electrical parts are securely carried by various subassemblies and when they are put together, all necessary connections are made.

The path of current through the motor may be described as follows: From the contact rollers 101 and 102 through the yielding spring supporting strap 107 to the stamping 110 thence through the spring pressed plunger 113 to the foot 23 of the strap 21, then through the reversing switch or controller and brush rigging and through the motor armature where the current is carried to the contact button 34 on the controller unit. This current will continue through the field winding to the field structure and thence to the motor frame. The extent of movement of the reversing switch 25 is limited by two stops 118 on the plate A.

In order to facilitate assembly of the motor, the two screws 42 and 43 use-d for fastening the controller brush assembly onto the plate A, the three screws 7 7 used for fastening the plate A onto the spacers 71, 72 and 73, and the two screws 83 used for fastening the plate G in position are all the same size and length. The two screws 68 used for fastening the field assembly onto the plate D are longer but may be made to have the same thread.

lVhen it is desired to assemble the outfit into the form of a toy electric power plant for operating various forms of toys, the parts are as above described assembled to bring them to the state or condition shown in Figure 10. Instead of using the units II and I to make up a toy locomotive one uses the units J, K and L to make up a toy power plant.

The unit J has a shaft similar to the shaft 89, and is provided with a gear 131 like the gear 90 and with bushings 132 like the bushings 92. The shaft J also carries at one end a comparatively large pulley 133 and at the other end a small pulley 134 and a pinion 135.

The unit K has a shaft 136 which carries a large gear 137, a drum 138 and a sprocket tees-leis wheel 1,39. In assembling these parts the unit K is first inserted in place. by passing. the shaft portion 136 throughthe .holes- 1 10 andv 141 in the plates A and D. To make improperassembly impossible, thesehole's are larger than other holes inthe side plates, and may be the only holes opposite one an: other. The unit J is lowered along the slots in; the same manner that the units H were inserted bringing the gear 131 in mesh with the-reduction gear unit F and bring the pine ion; 135 into mesh with the gear 137 on the unit K. As this gear 137 comes in behind the pulley 134; the unit- K is securely held. in position so that it cannot slide out of its. bearings.

The base plate unit L is then inserted; in. place. This unit as shown in Figures land 15 is in the form of an inverted channel. shaped stamping 150 adapted to support the power plant on a flat surface. This stamp.- ing150 has upwardly bent side lugs 151 corresponding with the lugs 117 carried by the unit I and adapted to pass outside the frame plates A and D as indicated in Figure 15. One pair of these lugs will secure the unit K in position,v the other pair merely passing up, outside the motor frame to facilitate: align.- ing the motor parts. The stamping 150 is also provided with two lugs 152 similar to.the upwardly bent ends 114 and 115 so that the unit may be fastened onto the spacers. 71 and 72 by the thumb screws 120 as indicated inv Figure 15. The stamping 150, also carries an upwardly and inwardly extendingshelf 153 adapted to pass inwardly between.

the lugs 118' on theplate'A. The end 1541 of the stamping carries apair of binding posts 155. and 156 one'of which is insulatively sup ported from the face plate. This insulated,

binding post 156 is connected by means of a conducting strip 157. with a plunger memher 158 similar to the. plunger member 113. The plunger member 158 is carried by the shelf 153 and the contact strip 157 is covered over and supported by-an insulating strip, 159.

When the units J, K and L are assembled as havebeen described, the electrical connections for the motor have been simultaneous-.

ly completed. The-current can pass from, the

binding post 156'through the strap 157 and plunger 158 to the-foot 23 carried bythe con-,

troller unit B and thence through the motor which has been described.

When the unit has been assembled for power plant purposes it will be apparent thatone. hasavailable a highspeed pulley 132, alow track. ThiS UtfitiS mad -pup. andlass'embled.

in ai-nianner generally similar to that em ployed. for the larger wide. gage outfit. The

outfit going to makeup. the toy locomotive and power plant as shown. in Figures 16- to; 20,,inclusive, consists of a number of separableunits having the same general characteristies. as the units shown in Figure 1 and capable of readily bein assembled to produce a toy locomotiveor power plant. These separate units, however; are, eXce at for. thetrucks and power shafts. of different detailed de sign althoughin general are for the same purpose.

The narrow gage: outfit includes. a side plate A, a combinedwrerersing switch and brush rigging-unit B, an armature unit C,

second side plateD, a field unit E, reduction; gearsF, a. gear cover plate G", locomotive trucks .H, a contact carrying bottomplate I, power shaft-s J; and K, a power plant base unit L, and ten screws.

The toy locomotiveof Figures 16 17, 20, 21 and 22 is assembled in a slightly difierent order than that above outlined with respect to, theform shown in. F igurel. The motor field unit E. islfirst mounted on the plate D. This mounting is accomplished by means of screws 200 which. pass through holes in the field structure and which are threaded into. spacers 201 carried by the. plate D. The plate- A is then placed in. position. This plate A carries fourspacers202, 203, 20-1, 205 similar to the spacers'Zl, 72 and 73 having reduced ends which fit into'the corresponaing holes in the plate D; Screws 206 are threaded to the spacers to fasten. the two plates together. The reduction gears F will then be passed onto. the supporting posts 207 as indicated in Figure. 16,'after which the plate G. may be fastened in place. by. the screws .208-threaded into. the posts 209 carried. by the plate. The plateGr. has wings as. indicated at 210 which. overlie thereduction gearsF" and hold them inplace on the studs 207. The. armature shaft unit C may. then be passed through a largehole 211 in the plate A so asto bring the end 212. of the armature shaft into the bushing 213 carried b'y the side plate Gr; This will .at the same time bring the driving pinion 214.011 the armature shaft into mesh with thelreducti'on, gears F." The. brush rigging controller unit 13 is their mounted in place onjthestuds 215'and 126. carried by the plate Aprovided for this purpose. Thestud 215 has a reduced outer end adapted to pass through the bushing 21? carried by the unit 1) while the stud 216 passes through the hole 218 in the insulating plate 219- of the unit B. This unit-also, carries a metallic bushing- 220 to; receive the: armature shaft 212. The unitB is'held in place by screws 221 threaded into the studs2l5 and 126. The locomotive truck units H. are next mounted in place by passing the bushings-222 similar to the bushing 132 upwardly through. the slots- 223 in the side plates A and D. This running gear is held in place by a transverse bottom plate I which is secured in place by thumb screws 224 threaded into the spacers 203.

The field unit E is made up to have the usual laminated field structure 230 and field winding 231. It also carries two sheets of insulation 232 and 233 between which the coil 231 is wound. These insulating members are designed so as to fit into the large slots or openings 234 and the small slots or openings 235 in the plates A and D. A current conduct-or 236 indicated in dotted lines in Figure 20 carries, at its lower end a plunger 237 cooperative with the lead in conductor 227. This conductor 236 is connected to one side of the field winding. The other side of the field winding is connected to a metal strip 238 carried in the upper front side of the field structure as indicated in Figure 20. This conductor strip 238 carries a forwardly extending plunger 239 adapted to pass through a hole 240 in the front plate A. The laminated field is held together by rivets in the usual manner. The heads of these rivets passing out through small alignment holes 241 in the plate D.

The armature unit C is of more or less conventional construction having the usual shaft 212, pinion 214, armature field 215, windings 216, and commutator 217.

A brush rigging controller unit B as shown in Figures 17, 21 and 22, comprises as has been described, an insulating sheet or plate 219 on which all of these parts are mounted. This unit also includes a current supply terminal 245 adapted to engage the plunger 239 when the parts are assembled into position. The plate B also carries an oscillatory reversing switch element 246 similar to the reversing switch 25 heretofore described in detail. The fixed contacts 247 and 247 of the reversing switch are each connected to brush rigging 248. The other fixed contact of the reversing switch is indicated at 249. It is connected by a strap 250 with the bushing 217 through which the stud passes, thereby grounding the circuit.

The form of brush rigging here shown, is made up out of a simple sheet metal stamping. The insulating plate 219 is provided with two openings 251 and 252 having circular ends 253 and narrow slots 254. The brush rigging stampings have cylindrical portions 255 adapted to pass through the enlarged ends of the slots, and also prongs 256 and 257 which pass through the narrow portion 254 of the slots. over into the insulating plate as indicated in Figure 17. The stamping also has two parallel portions 258 and 259 which extend from the holes 253 back to the conductor plates 260 which are connected to the posts 247 and 247. The ends of these brush rigging stampings have outwardly bent feet 261 which overlie These prongs are bent the conductor plates 260 and which are held in close contact to the same when the prongs 256 and 257 are bent over against the outside of the insulating plate. The brush 263 is carried in the cylindrical part of the brush holder. This brush is carried on the end of a spring 264 which is coiled about an anchor screw 265. The end of a spring 266 is passed under an inwardly bent prong 267 011 the brush rigging stamping. The spring is also held in behind a bent over ear 268 which prevents the spring moving the brush out of the holder. The prong 256 may, if desired, be provided with posts 269 adapted to receive clips to connect in head lights so that the headlights are lighted in accordance with the direction of travel of the locomotive.

The plate L shown in Figures 18 and 19 is in general similar to the base plate L shown in Figure 1. It is provided with upwardly extending prongs 270 adapted to overlie the slots 223 in the socket plates A and D and hold in place the shaft J. It is also provided with binding posts 271, one of which is connected to a contact post 272 cooperative with the terminal 237. The base plate L is provided with an apertured inwardly extending flange 275 to receive the aligning lug 229.

The motor construction shown in Figures 115 inclusive forms the subject matter of divisional application Serial No. 513,071 filed February 3, 1931.
