ELECTRICAL INDICATOR.

SPECIFICATION forming part of Letters Patent No. 709,806, dated September 23, 1902.

Application filed November 29, 1901. Serial No. 84,138. (No model.)

To all whom it may concern:

Be it known that I, HORATIO S. TITTLE, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Electrical Indicator, of which the following is a specification.

This invention relates to electrical apparatus, and particularly to apparatus of this characteradapted to indicate, register, ordesignate the means by which the circuit is closed; and one of the objects of the invention is to provide an apparatus of this general character which is simple and cheap in construction and at the same time positive and effective in operation.

Another object of the invention is to provide means for operating the movable parts of the apparatus and stopping the same at a predetermined time or place.

\Vith these and other objects in view the invention consists, essentially, in the construction, combination, and arrangement of parts substantially as more fully described in the following specification and illustrated in the accompanying drawings, forming part of this application, in which Figure 1 is an enlarged front elevational view of the apparatus, showing the casing and dial partly broken away. Fig. 2 is a detail view of a portion of the apparatus, showing the segments and movable parts in elevation and the dial and easing removed. Fig. 3 is a central sectional view with the casing removed. Fig. 4 is a side elevational View of the construction illustrated in Fig. 2 with the casing partially removed; and Fig. 5 is a fragmentalview, partlyin section, on the line 5 5 of Fig. 3.

Similar characters of reference designate corresponding parts throughout the several views.

This invention may be used in connection with cash-registers or other apparatus or machines wherein it is desirable to indicate that particular element of the apparatus or ma chine which is operated at a certain time; but it is to be understood that the invention is in no manner limited to use with cash-registers, and the same is illustrated as operated by an ordinary circuit-closing device, as the connections with the keys of a cash-register would be understood and does not form a part of this invention.

Referring to the drawings, and particularly to Fig. 1 thereof, the reference character 1 designates a frame or casing, upon which may be secured in any suitable manner a top or cover 2, preferably provided with an observation-opening 3, which may be covered with transparent material 4 in order that the characters upon the dial may be observed therethrough when brought thereunder, as will be readily understood.

Mounted upon the back 6 of the casing by means of spacing-posts 7 or other devices is a plate 8, upon or in which is preferably mounted a plurality of contact plates or segments 9, suitably insulated from each other and from the plate, if the latter is formed of conducting material, substantially as shown at 10, and the segments may be secured in position by means of attaching- screws 11 and 12, and they are each preferably provided with electrical connections 13, having stationary contacts 14E of any suitable character, by means of which the circuit through the segments may be closed, substantially as hereinafter more fully described.

Mounted or secured upon the plate 8 is a disk 15, preferably constructed with an elongated hub 16, Fig. 3, within which is mounted a shaft or spindle 17, carrying a large sheavewheel 18, preferably having secured thereto a disk or facing 19, provided with a hub 20, having a set-screw 21 to secure the sheavewheel 18 in position upon the shaft 17, the latter being preferably provided with a fixed disk or circular plate 22, substantially as shown in Fig. 3 of the drawings.

Secured above or upon the disk 15, preferably by means of the attaching-screws 23; which pass through the plate 8 and through said disk, is a cylindrical casing or cap 24, desirably constructed with an opening or slot 25 to admit the entrance of a spring contact-finger 26, secured upon an insulating-block 27 upon the cap 24: and provided with an electrical connection 28 with trical supply.

Mounted in the hub 29 of the cap 24 is an indicator-shaft 30, having an end of soft iron, carrying a recessed disk 32 to receive a helix or coil of wire 31 and forming one pole of an electromagnet, or when taken together, as hereinafter more particularly described,forming an electromagnetic clutch, one end ofthe wire coil 31 passing throughthe insulation 32 to a contact-ring or other device 33, preferably secured around the shaft 30, but insulated therefrom and adapted to receive a spring contact-finger 26, substantially as before described.

An angle-arm 34 is preferably mounted upon the shaft by means of a hub or bearing 35, carrying a set-screw 36, whereby the arm may be adjusted on the shaft,and mounted in the free end of the arm is a split stud 37 or like device carrying a binding-screw 38 and adapted to receive and retain a spring the source of eleccontact-piece or trailer 39, constructed to.

travel over and make con tact with each of the segments 9 to close the circuit t-herethrough, hereinafter denominated the magnetic or clutch circuit.

Secured upon a block 40 or in any other manner in the lower part of the main frame or casing is an ordinary motor or equivalent device 41, provided with suitable electrical connections and 46, respectively, with a battery 48, and a relay 49, which in turn are connected with each other by a connection 47, substantially as shown in Fig. 1 of the drawings.

The armature-shaft 42 preferably carries a small sheave-wheel 43, constructed to receive a belt or cable 44, which passes thereover and over the large sheave-wheel 18 upon the driven shaft 17, whereby the latter is rotated when the motor-circuit just described is closed, it being normally open.

Another battery or source of electrical supply is preferably employed having a connection 51 with the relay 49, which is in electrical communication with the contact-finger 26 by means of the connection 28 before de scribed, and the battery 50 is provided with a connection 52, having stationary contacts 53, between which and the stationary contacts 14 are mounted circuit-closing devices or keys 54, having a suitable connection 59 and preferably spring-elevated, so as to normally be in contact with the contact-points 14.

The operation of this inventiongvill be readily understood from the foregoing description when taken in connection with the accompanying drawings and the following eX- planation thereof: the motor circuit embraces the battery 48, the connection 45 to the binding-post on the motor-frame, through the motor to the binding-post 56, the connection 46 to the relay 49, and thence back to the battery or source of electrical supply through the connection 47; but it will be understood that the motor-circuit is normally open by means of the relay 49 and that the armature-shaft 42 is normally at rest and only revolves when one of the circuit-closers 54 is depressed into the position shown at 57, Fig. 1 of the drawings, when the magnetic circuit is broken through the segment 58, upon which the trailer 39 is shown as resting, the same having traveled around over the enlivened segments until it arrived at the dead segment 58 and stopped there. When the armature-shaft 42 is rotated by the closing of the motor-cicuit through the relay 49 by the depression of the circuit-closer 54, then the small sheave-wheel 43, carried by said shaft, is rotated, together with the belt or cable 44, passing thereover and over the large sheavewvheel 18 upon the driven shaft 17, carrying the disk 22, in contact with which the electromagnetic clutch is normally held through the action of the magnetic circuit passing therethrough from the battery 50, connection 51, relay 49, connection 28, contact-finger 26, contact-disk 33, helix or coil 31, indicator-shaft 30, arm 34, trailer 39, segments 9, segment connection 13, stationary contacts 14, circuit-closers 54, and connection 52 back to the battery50. When the electromagnetic clutch is in contact with the disk 22 of the shaft 17, then the indicator-shaft 30 is rotated by the rotation of the driven shaft 17 and carries the arm 34, supporting a trailer39, which travels over the segments 9, and the indicator-shaft 30 also carries a dial or equivalent device 59, preferably provided with numbers or other characters upon the periphery thereof,whereby each nu mber upon the dial becomes visible as the same passes under the observation-opening 3 in the top or cover 2 of the apparatus, as indicated in Fig. 1 of the drawings, the number 30 being here shown. Thus if the circuit-closer or key 54, connected with the segment 30, is depressed the circuit therethrough is opened and the segment 30 becomes dead or unenlivened, so that when the trailer reaches that segment it will stop thereon, being assisted by the ordinary breaking devices, thus bringing the number 30 upon the dial below the observation-opening 3, as shown, so that the number of the key or circuit-closer depressed will become known, and the trailer will remain upon the dead segment 30 and the number 30 will be displayed as long as the key for that segment shall remain depressed.-
