BRUSH RIGGING.

Application filed June 9, 1923.

of New Jersey, have invented certain new and useful Improvements in Brush Rigging, of which the following is a specification.

The present invention relates to brush rigging and more particularly to a device for holding the brushes in toy electrical devices.

In manufacturing toy motors it is desirable to provide suitable brushrigging which is capable oi easy disassembly for purposes of repairs, and for replacement of the brushes. In certain types of these motors, such as those designed for use in toy electric trains it is desirable to arrange the brush rigging so that it can readily be removed car or locomotive of which. it forms a part. The embodiments of the invention to be described in the present application have been developed more particularly for use with a toy electric locomotive or car.

Objects of the present invention areto provide a substantial brush rigging tor the above purposes which will be capable of easy removal for inspection and repairs, and 0 one which may be made in large quantities in an inexpensive manner so that all parts may be easily interchangeable.

Another object of the invention is to provide a brush rigging in which the brushes and supporting devices may be assembled as a unit and then this unit readily fastened in place alongside the comn'iutator with which the brushes are to cooperate.

In the accompanying drawings there. is shown for purposes of illustration one of the many possible embodiments in which the present invention may take form, together with modifications of certain parts, it being understood that the drawings are to be conthan limiting the same. In these drawings:

Fig. 6 is a view similar to Fig. 1, taken in the direction of the arrow 6 of Fig. 7, and showing a modified form of brush lead connection,

Fig. 7 is an elevational View of the structure shown in Fig. 6 takenjfrom underneath the vehicle, and

Fig. 8 illustrates a further modification.

Referring now to the Figs. 1 to 5 of the drawings, the side frame member of the toy vehicle is shown at 10 in the form of a fiat piece of sheet metal. This frame member carries the running gear here shown in the form of flanged wheels 11, 11 mounted on shafts, 12, 12. It is of course understood that the other side of the vehicle is provided with a somewhat similar frame member. The frame member 10 is also provided with a hole 13 adapted to act as a bearing for the armature shaft 14 and with notches 15 and 16 for purpose to be described. A flat sheet metal plate 17 is provided with projections 18 and 19 which are adapted to tit into the notches 15 and 16 in the frame member. The plate 1'7 is also provided with a threaded aperture 20 to receive a screw 21 which is passed through the frame member 10 from the outside as indicated in Fig. 4 and, in dotted lines, in Fig. 1. The screw and the lugs and notches cooperate to removably fasten the plate in place on the side frame.

The plate 17 extends up above the armature shaft 14 as indicated in Fig. 1, at 22 and 23. The metal between the upper p'ortions 22 and 23 of this plate has been removed in order to provide an open slot which extends all the way to the upper edge of the plate, the slot being made wider than the commutator shown at 24.

A sheet of insulation 25 is fastened to the sheet metal plate 1'? by means of screws 26 and 27 and his sheet oi insulation, as is apparent in the drawings, has two portions which extend upwardly past the armature shaft. These upwardly extending portions are also separated in a manner similar to the parts and 23 of the plate 17. Sheet metal brush holders 28 and 20 are fastened to the insulating sheet by means of screws 30and 31, and prongs 32 passed through the insulation and bent over as shown in Fig. 3. These brush holders may be of any convenient form but are here shownas made of a piece of sheet metal by suitably cutting and folding the same. In addition to the prongs 32 above mentioned these brush holders are provided with brush boxes 33 adapted to contain brushes 3%, and with screw receiving apertures 35 adapted to receive the screws 30 and 31. A prong 36 is located in a position to hold the brush spring when the brush is out of the box. The brush boxes'33 are cut away as indicated at 33 so as to effectively clear the shoulder 2% on the armature and permit the brush to cover practically the entire length of the comma: tator segment. The screws 30 and 31 in addition to fastening the brush holders to the insulation, each serve as a retainer for the upright portion 40 of the brush holder.

As shown in Figs. 1 and 2, armature leads I a1 and 42 may be connected to the screws Hand 51 of sheet metal.

31 and 30. v

The plate 17 and insulating sheet 25'with brush holders attached make up an assembled unit which may be readily put into the machine. It is only necessary to slide this made up unit upwardly from the botv tom of the car, bring the notches and pro.- jectionsin alignment and fasten the parts to the car by means of the screw'21. The leads are then connected in place and the brushes inserted.

lVhen inspection is desired, or the boy usingthe car wants to satisfy his natural curiosity, it is merely necessary to disconnect the armature leads, take out thescrew 2 1 and slide the parts down away from the commutator; The springs 37 may be placed on the prongs 36 to prevent losing the brushes by the springs throwing them away. It is, of course, obvious that the open slot inv the upper part of the sheet metal plate and the insulating sheet permit the withdrawal of the parts downwardly, In order to assist one in handling the parts there may be provided if desired a finger grip 43 which projects outwardly from the bottom of the frame member 10.

The structure shown in Figs. 6 and 7 is, in general, the same as that of Figsal to 5, and corresponding reference characters are used forthe corresponding parts. Instead of leads in the form of wires fastened to the brush holders, there are here shown leads or connectors in the form of bent pieces These connectors are preferably soldered to the brush holders at 59. and and are provided with out= wardlybent ends'54 and 55. The leads 56 for the armature circuit are passed through holes 57 in a block of insulation 58 and are fastened to the bent ends 54 and by screws 59 threaded into the insulation. The insu lating block is mounted on the locomotive in any convenient manner, and is cut away as shown at 60 to provide space for inserting or removing the plate 17 and part-s carried thereby. As here shown, the block 58 also carries the current collecting devices 61 adapted to make contact with a third rail 62. To remove this form of brush rigging the screws 59 and 21 are removed, and the plate slid out of place.

The structure of Fig. 8 differs from that of Figs. 6 and 7 in that the block of insulation 58 is provided with permanent binding posts 63 for the'leads, andin that these binding posts have exposed contact surfaces 6a to contact with the bent ends 65 and 66 of the leads or connectors 67 and 68. This form of brush rigging may be removed bodily upon removal of the screw 2 1.
