MAX 0. KUHN AND HAROLD C. SHOOLBRED, 0F MONTREAL, QUEBEC, CANADA, ASSIGN- ORS OF ONE-THIRD TO AGNES M. SHOOLBRED, OF MONTREAL, QUEBEC, CANADA.

INDICATOR.

To all whom it may concern:

Be it known that we, MAX 0. KUHN, a German subject, and HAROLD C. SHOOLBRED,

a British subject, citizens of Germany and Canada, respectively, residing at Montreal,

in the Province of Quebec and Dominion of Canada, have invented certain new and use' ful Improvements in Indicators; and we do hereby declare the following to be a full,

clear, and exact description of the inven tion, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to indicators and the primary object of the invention is to provide an indicator which may be mounted upon street cars, railway cars or the like, and is adapted for acquaintingpedestrians or Wheel traflic of the approach of a second car from the opposite direction to which the car upon which the indicator is mounted is traveling.

Another object of this invention is to provide an indicator as specified, which includes a magnet carried by the front end of the car and a bar movably carried by the car and extending rearwardly from the front end of the car and being positioned in spaced relation to the magnet, which bar is adapted for being acted upon by a magnet of a car passing the car upon which it is mounted for operating a signal.

The indicator may be used upon street or railway cars, or by locomotives, for indicating the approach of a train, when the bar is movably mounted alongside of the track or for any other analogous purposes.

With the foregoing and other objects in view this invention consists in such novel features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings and claimed,

In describing the invention in detail reference will be had 'to the accompanying drawings wherein like characters designate like and corresponding parts throughout the several views, and in which Figure l is a side elevation of a street railway car showing the invention applied thereto.

Fig. 2 is an end view of a railway car.

Fig. 3 is a fragmentary plan view of a Specification of Letters Patent.

Application filed January 28, 1916. Serial No. 74,917.

I indicator.

Fig. 5 is a diagrammatic View of the circuit used in the operation of the signal.

Fig. 6 is an end view of a car showing a modified form of indicator attached thereto.

Fig. 7 is a sectional view on the line 7-7 of Fig. 6, showing the manner of operating the modified form of signal or indicator.

Fig. 8 is a. fragmentary elevation of the .rear end of a street railway car showing another modified form of the indicator applied thereto, and a Fig. 9 is a perspective view of the modified form of indicator or signal illustrated in Fig. 8 and showing the manner of operating the same.

Referring more particularly to the drawings, 1 designates an ordinary street railway car as an entirety, which has an electrical magnet 2 attached to and suspended from the under surface of the front end of the floor of'the car, as clearly shown-in Fig. 1 of the drawings. The car 1 has a bar 3 pivotally connected thereto as is shown at 4, which bar is constructed of iron, steel or other metal,'which is acted upon by magnetic energy of a magnet.

A plurality of spiral springs 5 are connected to the bar 3 and to depending brackets 6. The springs 5 automatically return the bar 3 to its normal position after it has been acted upon and moved outwardly as indicated in dotted lines in Fig. 2, by the action of amagnet carried by a. second car which'ispassing the car upon which the bar 3 is mounted.

The bar 3 has. an arm 7 connected thereto, which is constructed of any suitable nonconducting material and has a contact 8 car- 'ried by the upper end of the same which is adapted for engagement with the contact 9 carried by the car structure. The contact 9 is interposed in the electrical circuit, utilized for operating the signal or indicator generically indicated by the numeral 10. The circuit 11 which is utilized for operating the signal 10, is normally broken at the contact point 9, so that when the contact 8 is moved into engagement with the Contact or switch 9, the circuit is completed which permits the current to flow from the battery 12, through a light bulb indicated at 13, a solenoid 14 and a bell or buzzer 15, back through the contacts or switch 9 to the battery as shown in Fig. 5 of the drawings. The preferred form of the signaling mechanism 10, includes a housing or casing 20 which is attached to the rear end of the car 1 and has a transparent window or windows indicated at 21 and 22 formed in the outer visible side 23 of the same. The'transparent windows 21 and 22 may have any suitable characters printed thereon, such as Stop, Car coming or the like which will be painted or printed on the transparent window so as to be visible in the day time. The front side 23 of the casing 20 has a pair of shutters 24 and 25 pivotally connected thereto, as is shown at 26, which shutters normally cover and hide the transparent windows or panes 21 and 22. The shutters 24 and 25 have angle arms 27 connected thereto, which are connected through the medium of links 28 to the cores 29 of solenoids one of which is indicated by the numeral 14 in the circuit illustrated in Fig. 5. Incandescent light bulbs 31 are also carried by the casing 20 rearwardly of the transparent panes or windows 21 and 22, and they are also interposed in the same circuit with the solenoids. The casing 20 has a cowl 33 formed upon its upper end in which a bell 34 is mounted. The bell clapper 35 is operated by the usual electrically operated construction 36 which is positioned interiorly of the housing 20 and the bell operating structure 36 is also connected in the circuit 11. When a second car is approaching the car upon which the improved signal and bar 8 is mounted, the magnet 2 carried by the approaching car will attract the bar 8, moving it outwardly as indicated in dotted lines in Fig. 2 of the drawings, which will move the contact 8 into engagement with the contact 9 and close the circuit through the battery 12, light 31, solenoid 30 and bell operating structure 36. When the circuit is closed through the solenoid 30, it will act upon the central cores 29, moving them for raising the shutters 24 and 25 into a horizontal position and permit of the eX- hibiting of the transparent pane 22 upon which a warning signal is printed. Simultaneously with the raising of the shutters 24 and 25, the light 31 will be ignited and the bell structure operated for sounding a signal for attracting the attention of pedestrians. or wheel trafiic.

In Figs. 6 and 7 of the drawing, a modified form of the signal or indicator is shown, which comprises a hingedly supported plate 40 which carries the sign or warnings. The plate 40 has an angle lever 41 connected thereto, which has a slot and pin connection indicated at 42 with a link 43 which is connected to the core 44 of a solenoid 45. llhe solenoid 45 is operated upon the closing of a circuit through the contact 9 for swinging the plate 40 outwardly in the position as indicated in dotted lines in Fig. 7 of the drawings. Coil springs 46 are connected to the hinged plate 40 and automatically return it to its normal inoperative position when the circuit is broken through the contact 9.

In Figs. 8 and 9, still another modified form of the signal or indicator is shown, which comprises a plate 50 which has an ear 51 formed upon its lower corner by means of which ear the plate is pivotally connected to a car structure. An angle arm 53 is connected to the car 51 and has a slot and pin connection with a bar 54, which bar is in turn connected to the central core 55 of the solenoid 56, so that upon operation of the solenoid the plate 50 will be operated for movement into or out of operative eXhibitive position.

If it is so desired, the indicator at the back of the car may be operated either by electric transmission or directly, from the movable bar, without departing from the spirit of the invention, and also the magnet in the bar may be adjusted underneath, at one side of, or on top of the car as desired by the person installing the improved indicator.

From the foregoing description taken in connection with the accompanying drawings the advantages of construction and of the method of operation of the improved indicator will be readily apparent to those skilled in the art to which this invention appertains and, while in the foregoing description, the principle of the operation of this invention has been described together with various features of construction, it is to be understood that certain minor features of construction, combination and arrangement of parts may be altered to suit practical conditions provided such alterations are comprehended within the scope of what is claimed.
