CHART FOR SIGNAL SYSTEMS.

Application led September 12, 1924:. Serial No. 737,227.

This invention relates to charts, and particularly to a chart to be used in connection with a signal system using a plurality of dierent colored lights which are flashed in various combinations, and has for an object to provide a means for quickly indicating the individual being called.

With the foregoing and other objects in View, I have devis-ed the chart illustrated in the accompanying drawing forming a part of this specification, similar reference characters being employed throughout the various figures to indicate corresponding elements. In this drawing,

Fig. l is a view of my improved chart showing how it is laid out for a system employing siX different lights of different colors, and

Fig. 2 is a similar view showing a layout for a system employing three different colors of lights only.

In this type of signal systems there are as a rule a plurality of stations ,located at different points desired, and each station has a set of lights including one light of each color to be used, the set of lights being the same for each station, Aand the signals are made by flashing these different colored lights in different orders or combinations from a central control station. For example, th-e control station may be at the telephone exchange in a department store or factory to be operated by the exchange operator, and when any yemployee notices his signal being flashed he may call this operator and learn who wishes to get in communication with him. 0r if another employee notices his signal and knows where the employee is whose signal is being flashed he may notify him that he is wanted. In the particular system for which this chart is designed the lights are flashed in sets of either one or two colors. If a single color is used for the signal it is flashed in three dierent ways, that is, a single flash with a considerable interval between any two flashes, two flashes with an interval between the second and third flash twice the interval between the first and second flashes, or three comparatively rapid flashes of the same lamp equally spaced. If a Combination of two differ-ent colors are used the signal comprises one flash of one color fol lolwed by two flashes of the second color, all Vof the fasl'les having. however, the time interval between them. fllicniffo,`

first or single fiash may be used as a key for indicating whom is being call-ed by any particular signal.

My improved chart, an example of which is illustrated in the accompanying drawing, employs this principle. Referring to Fig. l. the chart comprises a plurality of bars l0 preferably arranged horizontally and one above the other, although, of course different arrangements may be employed if desired, and each bar is of a different color, one bar corresponding to each of the differently colored lights employed at the various stations of the signal system. In the present case each station has six lights colored white, green, yellow, blue, red and purple, and there is a bar l0 for each one of these light-s and colored the same color as its corresponding light. Thus on the chart bar No. l is white, bar No. 2 is green, bar No. 3 is yellow, bar No. l is blue, bar No. 5 is red and bar No. 6 is purple, and the surface shading on these bars is `made Yto indicate these colors. Each bar has associated with it a plurality of indications of different colors, there being an indication for each color of light used in the system and arranged with respect to the bar in the same order that they are arranged at the station. Thus referring to bar No. l the indications ll correspond to the signal lamps at the various stations. are of the same color as these lamps and are arranged in the same order, and to more nearly simulate the couditions at the stations they are preferably made of an outline corresponding to the shape of an electric light bulb, and these indications are exactly'the same for all of the bars above mentioned. Thus for each bar lO the light indication No. l is white, No.' 2 green, No. 3 yellow, No. l blue, No. 5 red and No. 6 purple, and this is the arrangement of lights at the signa-l stations.

Each bar 10 has associated with it identificafion means for indicating whom is being. called by any particular signal. Thus associated with each bar lO is aseries nf columns l2, there being a column in alignnient with each light indication ll, each column in the present case extending in a vertical line immediately beneath its particular light indication, and located in these columns are indications to represent the second or second and third flashes of the signal. These indications take different ably small er ci? :terms tut are prefs llO llO

`= be flashed in the signal.

the same color as the lights being flashed with which they correspond. Thus for eX- ainple, in any column 12 under light No. 2 or the green light, these indications will also be green, and in the column under the yellow light they will be yellow and so on, and the number of these colored indications for any given signal will correspond to the number of times that particular light will Thus the horizontal bars 10 correspond to or represent the first or single flash of the signal and the indications 13 correspond to or represent the second or second and third flashes in the signal, and located at one side of the columns 12 are identification marks corresponding to the various signals. These identification marks may be numbers as indicated at 14e or they may be the names of the various employees as indicated at 15.

The chart is used as follows: In identifying any signal which is being flashed we first note the single flash in the signal and then go to the bar 1() having the correspondingcolor. Thus if the signal is one white and two green flashes we first go to bar 1 which is the white bar. Vile then go down the column 12 under the green light No. 2 and we note that the t-wo green indications 13 are opposite No. 4 in the left hand column 14. Thus employee No. l is the one that is being called or Mr. Jones. Similarly if the first or single flash is blue and the other two white, the single blue flash will take us firstto bar No. l and under the column corresponding to the white light No. 1 we find two indications opposite No. 30, and so on for each color combination throughout the entire system. As indicated above, however, some of the signals may be made on a single lamp, as for instance where the signal comprises a single white flash with a considerable interval between successive flashes, or two white flashes with a short and a long interval, or three white flashes with equal intervals. In these signals we go to the bar 10 corresponding with the color of the light flashed the same as in the other signals and find the corresponding indications under the light 11 corresponding to the same color. Thus a signal of one white flash is signal No. 1, two white flashes No. 2, three white flashes No. 3, or one red flash is signal No. 33 under bar 5, two red flashes signal No. 34 under bar 5 and three red flashes signal No. 35 under bar 5, and so on throughout the system.

It will thus be apparent from Fig. 1 that in a system using siX lights i8 different si g'- nals may be given using not more than two different colors in any signal, and that any signal may be easily and quickly identified by first locating the bar 10 corresponding to the single flash and then locating the indications 13 for the remainder of the signal under the corresponding light on that bar. This same principle obviously may be einployed for systems having other than su: lights. For instance, in Fig. 2 a card is illustrated employing this principle for a system having three different lights only, in the example shown, white, blue and red. The principle, however, is exactly the saine as in the hrst form, there being a bar 10 colored to correspond with each of the lights, light indication 11 for each bar and also corresponding with the lights, and the indications i3 with the identification marks 14 and 15 the same as in the first figure.

Having thus set forth the nature of my invention, what I claim is:

A chart of the character described comprising a plurality of bars of different colors, a plurality of light indications of different colors associated with each bar, and indicating means associated with each har comprising a series of columns having indications therein, there being a column arranged in alignment with each respective light indication and having correspondingly colored indications, and another column at one side of the first columns having indicating marks in alignment with those in said columns.
