REVERSING AND CUT-OUT SWITCH USED IN ELECTRIC STREET-CARS, &C.

SPECIFICATION forming part of Letters Patent No. 561,839, dated June 9, 1896. Application filed February 26, 1896. Serial No. 580,887. (No model.)

To aZZ whom it may concern:

Be it known that I, GUSTAF VALLEY, of Cleveland, Ohio, have invented a new and useful Improvement in Reversing and Ont-Out Switches for Use in Electric Street-Cars, &c.,

of which the following is a full, clear, and exact specification.

This invention relates to improvements in the reversing and cut-out switches used in electric street-cars, the object being to pro vide a switch by which the reversing of the motors as well as the cutting out of either motor, whether forward or reverse acting, may be effected by a single switch, and the I 5 usual separate reversing-switch and separate cut-outs may be dispensed with. This object is effected by the novel construction, combination, and arrangement of parts here inafter fully described, and pointed out in the claims.

The essential feature of the invention is a series of fixed contactssuch, for instance, as the spring-actuated fingers used in connection with electric switches like the ordinary street-car controller, which fingers are provided with suitable electrical connections to the operating-circuit, and a number of conductingcontacts arranged upon a surface capable of being so moved as to bring the contacts thereon into contact with the fingers or fixed contacts, and thus bridge across be tween certain of the fixed contacts and pass the current through the same in predetermined courses, the moving contacts being arranged in various sets and series and electrically connected together relative to the fixed contacts and their connections in such manner as to effect the desired results. The moving surface may be plane or cylindrical; but the latter form is regarded as somewhat the more compact and to that extent preferable. For this reason the cylindrical form is shown and described, but without intending to limit the invention thereto.

In the drawings hereto annexed, Figure 1 represents in side elevation the barrel or drum of a reversing and cut-out switch constructed according to my invention. Fig. 2 is a plan view of the top thereof, and Fig. 3 is a diagram showing the development of the drum.

ing-bars J, &e., as the drum is rotated.

S represents the drum, composed of disks or sections (1, preferably annular, which are preferably arranged alternately with insulating-disks a, the whole being rigidly fastened together and firmly secured between the end plates Z), which, being rigidly affixed to the shaft 0, bind the whole into a rigid cylinder actuated by the handle cl, fitting upon the angular upper end of the shaft 0, which protrudes above the case 6, by which the controller and switch are inclosed. For the sake of clearness the case is omitted in Fig. 1.

J J 2 J &c., are contact-bars of conducting material affixed to and projecting from the periphery of the disks a, and which bars are located and arranged as shown in Fig. 3. The dotted lines connecting certain of the bars J, &c., of Fig. 3 indicate electrical connection between the bars so joined within the drum F F F, 03., are a series of spring-actuated contacts or fingers of the usual or any preferred construction, and are arranged and adapted to make contact with the conduct H H H etc, are similar contactfingers so located as to make contact with the conducting-bars K 1 K &c., of the controller-drum L as the same is rotated.

The rheostat and field connections are omitted, as they are of the ordinary type and are made, through fingers of the H series and the controller-contacts, in the manner familiar to all electricians.

T represents the trolley, G the ground connection, and A and B the motors. Shown in Fig. 3- to represent the armatures of the respective motors.

The fingers of the F series are connected, respectively, as follows: F to the finger H, F to the trolley, F to the finger H F to the forward-acting side of one of the motors, (designated as motor A,) F to finger 1P, F to the reverse side of motor A, F to the reverse side of motorB, F to finger H, F to the forwardacting side of motor B, and F to the ground connection.

The contact-fingers of the H series, so far as concern this invention, are connected as follows: H and H are connected, through the controller-contacts and other fingers of the H series, (not shown,) with the rheostat, &c.,

interposed, and H and H are similarly connected.

As the connections of the resistance, &c., through the controller-drum are as usual, the contact-fingers H H may be considered, so far as the reversing and cut-out switch is concerned, as directly connected, and the contacts H and H the same, and they will be so described. H is also directly connected with F, H with F H with F and H with F Referring to Fig. 2, it will be seen that the handle (Z, as there shown, stands at the off position, in which none of the fingers of the F series rest upon any of the contact-bars J, &c., and the current is cut off,and also that the handle stands midway between the forward moving andbackward-movingpositions. (Indicated in Fig. 3 by the line so Turning the handled to point in the direction of the dotted arrow 1 on Fig. 2 will bring the contact J and all the contacts in the same vertical line into contact with their respective fingers of the F series, 660., and the current will pass as follows, (see Fig. 3:) from the trolley through F, J, F, H, 1P, F J and F to the armature of motorA on its forward-acting side, and from its opposite or reverse side through F J J F H H F J F to the forward side of the motor B, and from its reverse side through F, J J and F to the ground, thus moving the car ahead with both motors. To cut out motor B and go ahead with motor A only, the handle d will be turned to the position indicated by the dotted arrow 2 of Fig. 2, which would bring the contacts J J J J under the fingers F,&c., and cause the current to pass from the trolley through F, J F, H, H F J F motor A, F, J J, and F to the ground, avoiding motor 13, which would thus be cut out. In a similar manner it will be seen turning the handle (Z to the position indicated by arrow 3 in Fig. 2 would cut out motor A and go forward with motor B only, and turning it to arrow 4: would reverse both motors, the current passing through F, J F, 11, H F ,J and F to motor A in the reverse or backward-acting direction,then through F J F H H ,F J and F to motor B in reverse direction, and through F J, and F to the ground, backing the car with both motors. Turning the handle to arrow 5 would cut out motor B and back with motor A only, while at arrow '6 it would cut out motor A and back with B only.

The positions indicated by arrows on Fig. 2 are to be marked by'suitable lugs, ribs, or letters on top of the controller-caseas, for instance, by the words and letters shown in Fig. 2-and it will be seen by Fig. 3 that whenever the handle d is at a point intermediate between any of the positions indicated by the dotted arrows the fingers F, &c., are between the bars J, &c., and the current is cut off. Bythis means the cutting out can be done in a fraction of the time required to throw a separate cut-out'switch, as the motion of the handle, already in hand, is very slight, and there is no possibility of any change in the action of the reversing-switch in cutting out, as all positions on one side of the off line are forward-acting and all on the other side are reversed. Further, the attention of the motorneer need not be diverted, even for an instant, from the track or road in front to cut out or reverse the motors, and no other or additional parts have to be handled by him than the usual two handles operating, respectively, the controller and the reversing-switch.
