REVERSING SWITCH FOR TOY ELECTRIG DISK-AIMS.

Application filed June so, was. Serial in. rates.

lFhis invention relates totoy railways, and more particularly to a reversing switch for controlling the direction of movement of the locomotive or train and simultaneously changing the headlights'of the locomotive in accordance with the direction of travel.

One of the objects is to provide a novel switch and an actuator therefor operated by a track abutment. Customarily' toy railways run on trackways of loop or circular formation and the train reverses at 'the end of each cycle of movement. The present con.- struction contemplates an arrangement which will reliably function to reverse the current to the motor as well as the headlights, in the manner set forth in the application of Frank S. (Quiver Ser. No. 9667, filed Feb. 16,1925.

Another object of the invention is to provide a novel track trip or abutment which may be readily set so as to cause the train to reverse or continue in its cycle, without refor toy use and which may be economically manufactured and assembled thereby enhancing the value of the invention from both a commercial and practical standpoint.

With the above and other objects in View which will more readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated and claimed.

A preferred and practical embodiment of the invention is shown in the accompanying drawings, in which Figure 1 is a top plan view of the improved construction.

Similar reference characters designate corresponding parts through the several figures of the drawlngs.

As previously indicated the present invention is directed to a novel switch actuating means for controlling the motor and" reversing the headlights on the locomotive, and in that respect represents a carrying forward of the idea disclosed in the Frank S Culver application previously referred to.

By reference to the drawings it will be observed that the motor unit designated generally as M is mounted on a frame F. carried in the usual manner by the wheelsfW" which travel upon the track that includes the rails of the switch The said frame F has oneside thereof extended as indicated at F thereby to provide a support or carrier for the novel switch unit designated generally as S and an actuator A adapted to operate in conjunction with an abutment B of the, track trip device designated generally as D, positioned in the trackway transversely of the rails. The novel features of the abutment B will be referred to more in detail hereafter.

Referring first to the switch unit S it will be observed that'the same includes in its organization a carrier plate designated genertill tit;

ally as 1 adapted to be pivotally mounted as indicated at 2 upon the frame extension F.

This carrier plate is provided with an offset.

or downwardly pro ecting arm 3 while the body thereof is provided with openings 1 whose function will presently appear. The said plate 1 is therefore pivotally mounted on the frame so as to oscillate, and has the upper part of its face opposite the frame covered by an insulation filler 4:. Attached to the intermediate portion of the filler 4 is a main bridge contact member 5 having the contact fingers 6 and 7 integral therewith. The said bridge contact 5 is secured to the insulating filler 4: by means of the fastenings 4*, the heads of which lie in the openings 1 thereby to avoid electrical contact between the bridge member 5 and the plate 1. The plate 1 is, of course, connected to the frame F and the frame is grounded to one of the rails of the track. Therefore, it is important to insulate the bridge member 5 from the plate 1 which is in the glOLlIld circuit.

The web portion of the bridge member 5 is covered by an insulating member 5 and the ground contact bridge member 5 having the contact fingers 8 and 9 is secured in position by the rivets 10 or equivalent fastenings passing through the bridge portion 5 and electrically uniting the contact fingers 8 and 9 with the plate 1, which, as previously indicated, is grounded through the frame of the machine. The contact lingers 8 and 9 are therefore ground contact fingers. In

' order that the plate 1 may lie flush with the face of the frame, the said frame is preferably cut out or depressed as indicated at F and F S to accommodate the heads of the fastenings 10.

WVith the arrangement described it will be understood that the switch member S includes the contact fingers 6 and 7 which are insulated from the ground contact fingers 8 and 9, and both are carried upon an oscillating plate pivotally suspended from one of the frame parts of the motor assembly.

The actuator A for engaging with the arm 3 is mounted directly beneath the switch S and preferably comprises a body 11 of disk-like formation having therein a notch 12 which provides the opposite shoulders 13 and 14;. Also the body of the member A is pivotally attached to the frame part F by a spring tensioned fastening 15 which frictionally clamps the actuator to the frame and provides looseness. Below the pivot 15 the body 11 is provided with a slot 16 adapted to cooperate with one of the posts P of the insulating terminal plate carrier designated generally as C, to limit the movement of the actuator as will presently appear. The lower edge of the disk-like body 11 carries the relatively radially projecting switch setting projections 17 and 18 and an'intermediate switch throwing projection 19.

These projections are preferably of angular formation at their outer ends as will be clearly observed from the drawings so that the horizontal portion thereof may readily engage with the abutment B.

As will be observed from the drawings the switch throwing projection 19 is shorter than the setting projections 17 and 18, or in other words does not extend as far outwardly from the periphery of the body 11 so as to insure clearance between the projection 19 and the abutment B, so that after the switch has been thrown it will not be again thrown as it travels back over the abutment until it has been reset by either one of the setting pro jections 18 or 19.:

The insulating terminal plate carrier C is preferably a plate of insulating fiber or equivalent material which is carried by the post 1 previously referred to and the additional posts P and P located at the upper part of the frame. Thus, the insulating terminal plate is carried by and spaced from the frame extension F and substantially covers the switch S and actuator A, and serves to mount the terminal contacts 20, 21 and 22 in such a way that they may be engaged at proper times by the contact fingers 6, 7, 8 and 9. The terminals 20 and 21 are connected by the wires 20 and 21 respectively with the armature and field of the motor M, said field being connected with the third rail R by the trolley T, (see Fig. 11). The terminals 20 and 22 are respectively connected to the front headlight H of the locomotive by the wire 20 while the wire 22 connects with the rear headlight H.

Referring to the track carried trip device which includes the abutment B it will be observed that the same includes in its organization a main clamp member 23 of substantially U-shaped formation at its intermediate portion, and having an upwardly extending rail engaging arm 24; at one end and an offset arm 25- at the other end carrying a rail engaging clip 26 which may be made secure by a fastening 27. The upwardly extending portions of the U-shaped body 23 are provided with horizontal slots to receive the extensions 28 and body portion 29 of the trip member 30. This trip member is provided at the portions between the upstanding sides of the part 23 of the body with the upright abutment B, while the opposite end is provided with a finger knob 31 to assist in slidably adjusting the member B so as to position it to be in or out of the path of the projections 17, 18 and 19 of the actuator A.

For the purpose of holding the slidable 1 member 30 in the desired set position any suitable and convenient means may be utilized, such for example as the spring 32 carried by the extension 25 and frictionally bearing upon the upper face of the slidable member 30 as clearly indicated in Fig. 3.

With the arrangement described it will be understood that the track trip device D includes means for gripping the outside rails R and B of the track, and positions the abutment B between the third rail R and the rail R. The slidable abutment B may be moved into or out of the path of the actuator A to either permit the free continued movement of the train, or its reversal, as desired by the operator.

' The operation of the device is ly as follows:

Assuming that the rails B, R and R are part of circular, oval or other continuous substantialtrackway, and the trip device D is mounted thereon and the abutment B set in position to engage the actuator A; and, also assumingthat the locomotive carrying the present switch device has been around the track once and is travelling in the direction of the arrow in Fig. 8, it will be apparent thatthe switch throwing projection "19 will shortly engage the abutment B to change the position of the switch S. With the switch 8 in the position shown in Fig. 8 the circuit will take the path shown in Fig. 12.

That is to say, when the train is travelling from right to left as shown in Fig. 8, the bridge contact fingers 6 and 7 engage with the terminals 20 and .21 while the ground contactincludin the finger 9 engages with the contact 22. bus, the current passes to the motor from the trolley T and also to the front headlightH through the wire 20 while the rear headlight H is extinguished due to the fact that the ground finger 9 engages with the ground terminal 22.

Again referring to Fig. 8 and assuming that the projection 19 has struck the-upstanding abutment B the result will be the position of parts shown in Fig. 9. As will be observed from the latter figure the finger 19 .is pushed above the top of the abutment B and the shoulder 13 of the actuator A has engaged the arm 3 to shift the switch so as to change the relative position of the contact fingers 6, 7, 8 and 9 thereby to reverse the current to the motor, extinguish the front headli ht H and illuminate the rear headli ht The direction of current flow when the motor is reversed may be observed from Fig. 13. From'this figure it will be seen that the main bridge contact fingers 6 and 7 engage with the terminals 21 and 22 while the finger A 8 of the ground contact en ages with the terminal 20. The effect of t is position of the switch is to cause thecurrent to flow of the wire 22 connected with the terminal &

Figs. 8 and 10 are switch throwing positions while Figs. 9 and 11 are setting positions. In other words the only time the switch S is thrown is when the projection 19 engages v with the abutment B. When'projections 17 or 18 engage with abutment B they'merely set the actuator A into position to effect switch throwing the next time thatthe projection 19 comes into engagement with the upstanding abutment B.

For example in Fig. .-8 with the train travelling in the direction of the arrow it will be apparent that the projection 19 will engage the abutment B which will have the effect of causing the switch S to be moved through. the engagement of shoulder 13 of the actuator with the arms 3, and-the projection 18 will be brought downwardly into the position shown in Fig. 9. Thus when the parts reach the position shown in Fig. 9 the current to the motor and to the headlights is reversed and the projection 18 will engage the abutment B and give the actuator A an idle movement corresponding to the distance between the shoulders 13 and 14 at each side of the notch 12 in the actuator A, thereby to bring the throwing projection '19 into the position shown in Fig. 10. Thus,

direction of the arrow in Fig. 11 the rojection 17 will engage the abutment B t ereby to shift the actuator A idly back to the position shown in Fig; 7 whereby it will be ready to throw the switch S when the pro jection 19 enga es with the abutment B.

Without furt er description it is thought that the features and advantages of theiinvention will be readily apparent to those skilled in the art, and it will of course be understoodthat changes in the form, proportionand minor details of, construction may be resorted to without departing from the spirit of the invention and: scope of the ap ended claims.
