srenatiiis .envien Application filed .Tune 22,

his invention relates to improvements in signal devices tor street-cars, and the main object is to provide means for signaling other cars and vehicle tratlic in the rear when the car is to stop to discharge passengers, and thus prevent rear-end collisions, protect passengers and save loss of time through unnecessary slowing up or stopping ot trathc going in the same direction with the car. Further objects will be disclosed in the course of the following speciiication, the invention being embodied and illustrated in the accompanying drawing, wherein:

Fig. 1 is a side elevation ot a street-car embodying` my invention.

2 is a diagrammatic view ot the electric circuit, the bei; l-l being shown in section.

Referring to the drawing more particularly and by reifer-ence characters. A designates a street-car having gates C, which are opened and closed by a crank D on a shaft E, operated by the inotorman, and all et which are of common and well known construction.

Enclosing a portion ot the sha-lt E is a box B, in which is arranged an electro-magnet F, and adjacent one end et' the magnet l? is a lever G, pivot-ally securee as at il, to the box, and adapted to oscillate between the magnet F and a stop or lug J. Ar spring l is connected at one end to the boi; and at its other end to the lever, and is so arranged that when the lever G moves 'from the magnet to the lug, or vice versa, the spring will pass over the center H and will thus yieldingly retain the lever either against the lug or the magnet.

A wire 3 connects the lever G to a rear stop or signal light 1, which in turn is connected to a battery 5 by wire 6*?. wire 8-9 runs trom the other terminal ot' the battery 5 to a contact point 10. which, when touched by the lever G. completes a circuit through the elements (l, l-l, 3, ll, 6 7, 5, S-Q and 10.

@ne terminal ot the magnet F connects with the wire S by a wire 11. The other terminal is connected by a wire 12 to a bell 1?) in the motormans compartment ot the car. rlhe bell 13 is 'further connected in circuit with a series of passenger-operated push button switches 14, 15 and 16 by wires 17e-i8, 17-19, and 17-20, respectively, and the push buttons 14, 15 and 16 are further connected in circuit to the wire 7 by the

respective wires

21, 22 and 23; thus completing a 1923. Serie-l No. 647,119.

circuit through the

elements

7, 5, 8, 11, F, 12, 153, 17 and the connecting wires to the switch 14, 15 or 16, which happens to be closed.

The operation and use oir' the device may be briefly explained as follows lhcn a passenger desires to leave the car at a certain street intersection he presses (for example) the button 15 upon app-roaching the intersection. 'lhis closes a circuit through ythe bell 13, thus signaling the motorinan to stop the car, and also completes the same circuit through and energizing the magnet F. rl`his pulls the lever G away from the stop J and to the magnet, thus completing the circuit through and energizing the lamp or signal When the passenger' releases the Vbutton 15 the signal. il will still be energized, as the spring K will keep the lever G in contact with the point 10.

The shaft E has a lug lill, with a hingedly connected spring held tip or portion E2, which slips over the lever G when the crank D is turned in the direction ot the arrow D1 to open thegates. lVhen the gates are to be closed, however, by turning the handle l) in the direction of the arrow D2, the member E2 engages the lever G and, in passing, throws it over against the lug J, thus breaking the con-tact G10, and cle-energizing the light 4i.

lt will thus be readily understood that when a passenger wishes to leave the car he pushes one of the push buttons, conveniently arranged for that purpose. This rings the bell 13, signaling the motorrnan, and also energizes the signal l, notifying the vehicles going` in the saine direction that the car is to stop at the next intersection so that the drivers et said vehicles may govern their actions accordingly.

The signal will, ot course, stay energized until the motor-man closes the gat-es, after the passenger has been discharged, at which time the signal circuit will be autor atically broken. and the traino will be tree to proceed.

It will be further understood that suitable modilications may be made in the device. and the circuit arrangement, as herein set forth, provided, however, that such modifications are within the spirit and scope ot the appended claim.

Having now therefore tullv shown and described my invention, what I claim to be new and desire to protect by Letters Patent position, an energizing circuit for the switch including a motornians signal, a manually operable oircultcloser, and the electromagnet of said electromagnetic switch, means 10 operable by tlie gate operating device to trip over the armature of sai-d switch, when it is moving in one direction7 but, when moving in 'the opposite direction to engage the armature switch and inove it from closed to 15 open positions.

In testimony whereof I affix my signature.
