These mechanin connection with an electromagnet; Fig. 1S, isms are constructed and arranged to operate a rear elevation of the battery-switch shown in combination and perform the resultdesired at the bottom of Fig. 1G, and Fig. 19 a diain the manner hereinafter described. 10o 5o grammatic view showing the arrangement of In illustrating and describing my improvecircuits. ments I will only illustrate and describe the mechanism which I consider to be new and essential for the purpose of disclosing myinvention to enable those skilled in the art to practice the same, leaving out of consideration old and well-known mechanisms, which would only tend to confuse and render ambiguous the novel features. I will say, further, that I will show and describe my mechanism in what I consider the preferred form, but do not desire to be limited to this form, as it will be evident to those skilled in the art that the details of arrangement and form may be varied without departing from the spirit of the invention.

I will first describe the regulator to be used in my system, (see Fig. 9,) but will not show or describeits ordinary time-keeping train, which is well known in the art. As is well known, schools are open but tive days in the week, being closed for Saturday and Sunday, and, generally speaking, there are no sessions of school during the evenings. In order, therefore, to permit the mechanism to be used only at the desired times either cday or night, I provide a regulator with means by which the main circuit is opened and closed at these times and the motor for operating the switch permitted to be operated or prevented from operating at other times. In order to provide mechanism of this kind, I use a dial A, which is secured by any desired means to the frame A of the regulator. This dial, which contains the names of the seven days of the week, is mounted upon a rotatable shaft a and provided with fourteen pin-holes, each pin-hole representing twelve hours. If it be desired to close the electric circuit on any of these days and, as shown in the drawings, for the daytime of Monday, Tuesday, lVednesday, Thursday, and Friday, the pins d are inserted in the pin-holes a2 of said dial. Arranged on the ring A2 and insulated therefrom are two spring contact-points @Sand a". These springcontacts are connected by means of the wires d5 and a with the main circuit, which includes an annunciator, the make-and-break mechanism, and source of electric energy, and as the week-dial rotates a pin a' will strike the contact-spring al and raise the same so as to bring it into electric contact with the other spring-contact, (see Fig. 9,) and thus close the main circuit. As shown in Fig. 9, when the dial is rotated, so that the pin is removed from operating the spring-contact,such contact a will drop and the main circuit be broken, thereby preventing the operation of the parts or the conveying of current to the annunciators.

In order to prevent the operation of the motor", which motor will be hereinafter described, I pivot a stop-lever having two arms Ai" and A4 to the ring A2 at al (see Fig. 9) and provide one of these arms with a block as, arranged to be contacted by one of the pins CU. As shown in Fig. 17, the motor is provided with a fan against which the arm A3 on the stop-lever may impinge to prevent it from rotating. When the parts are in the position shown in Figs. 9 and 17, the stop-lever is removed from the path of rotation of the fan, so that if all other means are free such motor can operate at the desired times. As the pins on the week-dial pass out of contactI with one arm of the stop-lever the upper end will drop and the lowerportion be moved over by means of the spring d, so as to contact the fan of the motor and prevent itspoperation until the next pin on the week-dial raises and removes such stop-lever from contact with the vfan of the motor.

In order to rotate the week-dial in a stepby-step manner and at the desired times, l provide the shaft upon which it is mounted with a notched wheel B, having any desired Vnumber of notches. As shown in the drawings, (see Figs. 12 and 14,) it has fourteen notches corresponding to the number of pins in the week-dial-one for every twelve hours of the week-thus providing for the movement of the week-dial once every twelve hours. This same shaft is provided with an independently-mounted compound lever l), arranged in the path of an arm B,which is connected with the hour-wheel of the regulator to rotate with the same, and during every twelve hours, or one complete rotation of the hour-hand, it will contact the compound lcver and move it to its limit in one direction and then release it, so that a coiled spring b may restore it to its normal position, as

shown in Fig. 14. The lever is preferably made compound or in two parts Zi and Zi?, as shown particularly in Figs. 13 and 1i, so that they have a very slight independent lateral movement for the purpose of oi'ierating the mechanism more efficiently. The lower lever is provided with a dog b3, arranged to engage with the notches or indices Z7* on the notched wheel, and the ring-'frame of the week-day dial mechanism is provided with a pawl Bg, arranged to engage the indices at determined times to position the dial. As the lever-arm is moved forward or in the direction indicated by the arrow in Fig. 14: the dog on the compound lever rides out of the notch with which it is in engagement by having its beveled front end contact the walls of the notch and force it out. The continued movement of the compound lever brings the hooked free end of the dog into engagement; with the next notch, and as the arm on the regulator-clock releases the compound lever the coiled spring b restores such lever to its normal position and brings the pin b5 on the upper lever into engagement with the lower lever, as shown in Figs. 13 and lat, so as to permit the trip B to strike the pawl and remove it from. engagement with the notched wheel and permit the dog (i3 to rotate the notched wheel one step in its rotation and bring the next pin or hole opposite the stoplevers and spring-contacts on the main circuit, so that if there be a pin in such hole such circuit will be closed and the stop mechanism operated so as to liberate the switchmotor.

It is Well known that less battery-power is required to operate electromechanism when it is operated successively than would be required to operate an aggregation of such mechanisms simultaneously. For instance, I may desire to arrange twenty-iive annunciators in a school-building and place them on five circuits, with ve annunciators on each circuit. If I operate these twenty-five annunciators simultaneously or during the same period of time, it would require a comparatively-large amount of electric energy, and as these annunciators should only be opererated or moved every tive minutes the energy used would be disproportionate to the Work performed. I therefore desire to provide mechanism to energize these circuits successively, but during such a short period of time that to all intents or for practical purposes it is simultaneous. In order to ac complish this result, I provide What I term a switch-motor, (shown particularly in Figs. I6, 17, and 18,) in which there is a frame C, having a train of Wheels adapted to drive and rotate what I term a rotating contact-shaft c. This train consists of two shafts c c2, having power-springs c3 thereon, and is provided With driving-Wheels C' and C2, which mesh with a pinion (not shown) on a shaft c4, such shaft bearing a Wheel c5, that engages with a pinion (not shown) on its rotating contact-shaft. This contact-shaft is provided with a two-ar med contact-piece C3, arranged during its rotations to successively contact the spring contacts or terminals c6, c7, cs, ci), and 010 and energize the main circuits that lead therefrom by means of the Wires ou, cl2, cl3, c, and 015. Ilorconveniencein giving signals or sounding the annunciator it is desirable to energize these currents every tive minutes. In order to accomplish this result by mechanical means and stop the mechanism at all other times, I provide a let-oft`, which is constructed and operated as follows: The contactshaft is provided With a wheel C4, which also engages and operates a dy or fan C7 by means of the pinion and shaft C8. The contact-shaft c is provided Witha notched disk C9 and is pre vented from rotating by means of the vibrating of a movable stop C10, which is pivotally mounted in a shaft C11. A second hooked stop C12 is pivoted in the same shaft and has its outer free end arranged to hold the iiy or fan from rotating, and consequently pre vent the motor from operating. In order to release the parts at predetermined times, I provide the main arbor D of the regulator with a pin-wheel d, bearing twelve pins done for every iive minutes-arranged to operate against the free end of a vibra-ting releasing-lever D'. This releasing-lever is pro vided with a connecting-rod d2, that connects with the stops Cw and O12 to operate and raise the same, so as to release the notched disk C9 and the fan or fly C7, and thus enable the one of its contact-arms successively closes,

and consequently energizes, the five circuits above named. As the pins d pass out of contact With the releasing-lever Dl the lever resumes its normal position, owing to the weight of the other parts, and stops the motor after the rotating contact-shaft c has madehalf of a revolution. In order to prevent the rotation of the contact-shaft through a greater period of time and longer than is necessary, I provide a third stop cl3 and the Wheel C5 with a pin d4. It will be seen that the connecting-rod of the releasing-lever raises this third stop into the path of the pin d4 and prevents the complete operation of the motor until the releasing-levell has resumed its normal position. At the same time it will be seen that it may make a partial operation, so that the stop C10 is removed from alinement with the notch i-n the notched disk C9. It Will thus be seen that there are three means of stopping the motor and makingand breaking the mechanisms from operatingfirst, the week-disk, With its pin-holes and pins, which are arranged to actuate the stoplever A5 and prevent the Yfan Olfrom operating; second, the vibrating stoplever d?, which is arranged to contact the pin dLl on the Wheel C5, and, third, the hook-stop C12, Which is also arranged to engage the fan C7 and be disengaged at desired times.

The batteries or sets of batteries are electrically connected with the frame of the motor, as shown in Fig. IS, by means of the Wires E, E, and E2, which lead to three sets of batteries. Each wire has a spring-terminal which bears on a contact-collar E3 of a rotating shaft e. This contact-collar is provided with an insulating portion c', and, as shown in Fig. IS, but one terminal or brush can be electrically connected with such collar at a time, so that but one battery or set of batteries is in position to be used. In order to rotate this shaft and consequently switch the electric connection from one set of batteries to the other at predetermined periods of tim-e, I provide such shaft With an index-plate El, having any desired number of notches. The shaft is further provided with a compound vibrati ng lever E5, arranged to be contacted by a pin on the wheel The lever is also provided with a dog e2 and the frame with a pawl e3. Such compound lever is further provided With a trip et, all constructed in exactly the same manner as the mechanism described in Eig. la. A coilspring @5 is used to restore the lever to its normal position. The arrangement of the parts is such that during the rotation of the motor-wheel c" the lever is moved over and its dog rides out of engagement With the in- IOS IIO

dex-plate, so that the moment such lever is released the coil-spring operates to throw it back, and the trip c4, moving the pawl out of engagement with the index-plate, permits the movement of such lever to rotate the shaft, with its contact-collar, one step in its rotation. The timing of the parts is such that each one of the battery-terminals is electrically connected with the contact-collar for a period of two hours and is out of contact with such part and at rest for a period of four hours. In other words, it takes six hours for the con* tact-collar to make a complete rotation, and as each battery or set of batteries are in contact for two hours out of the six they have four hours rest and time for restoration. This is a decided advantage in that it allows the use of primary batteries in an economical and efficient manner.

It may be found desirable to dispense with the mechanical stop mechanism and provide electromechanical mechanism. In order to accomplish this result, I provide the motor with an electromagnet F, as shown in Fig. I7, and one of the rotating shafts d10 with an armature f, arranged over the pole or poles of the magnet. Instead of having a releaselever (see Fig. 10) the pins may be arranged to bear against the brushj",which is insulated from the frame of the .clock and provided with a wire f2, that leads to a battery, and the frame with a wire f3, that leads to a corresponding wire fi and the magnet, while the wire f2 corresponds with the wire f2 in Fig. l0 and also leads to the battery. It will thus be seen that the magnet will be energized every five minutes and the stop and release mechanism operated every five minutes eX- actly in the same manner as the mechanical release mechanism.

Having described the regulator and the means by which I make and break the annunciator and main circuits, I will proceed to describe the annunciator.

In Fig. l of the drawings I have shown a front elevation of the annunciator, which is provided with a dial having the usual hourmarkings and an outer ring bearing markings for every five-minute movement of the hour-hand, making one hundred and fortyfour in all, or twelve between each hour. I provide a corresponding number of sliding contact-pieces G at a point inside of the hourmarkings, which are confined and held in place by means of a holdingering G', which may be secured to the dial by means of screws g, as shown in the drawings, or in any other desired manner, and is slotted, as at g', so that the sliding contacts may be held in the desired position. These sliding contacts are connected with one terminal or pole of a local or su pplemental circuit and the hour hand or shaft with a second pole of the local circuit, which includes a battery and a bell. The hour-hand G2 is provided with a brush g2, which is arranged underneath the same,

so that it may contact the sliding or adjustable contacts whenever they are drawn out, and thus close the local circuit at the desired time or times, as shown in Figs. l, 2, and It will thus be seen that, if desired, the annunciator will close a local circuit, give a signal, or sound an alarm during any ve minutes of each of the twelve hours.

To operate the pointers or hands on the annunciator at the desired times, I provide a train of wheels and pinions g2, g4, g5, g, gl, g2, and g and a fly or fan shaft and pinion g1", the initial or driving shaft being provided with a power-spring G3. The shaft upon which the wheel and pinion (/and Q7 is mounted is provided with a notched disk gil, having but two notches and which is arranged to be engaged by a vibrating stop Q12, which is pivotally mounted on a rock-shaft gm. The same shaft bears a limiting-stop g1, which prevents the parts from rotating but a portion of their distance until the magnet which operates the same has been deenergized, as hereinafter described. To release the stop mechanism from engaging with the notched disk, I provide an electromagnet I-I, which is electrically connected with a source of electric energy and with one of the battery-ter minals by means of the wires h or 7L', so that when the rotating contact of the motor electrically closes a circuit such magnet is energized, the armature 7a2 pulled down, and by means of the rod h3, that extends therefrom, the stop Q12 raised out of engagement with the detent-disk and its limiting-stop gm raised into position to stop the pin g1, but permitting the detent-disk to make a very short part of its rotation. As soon as the magnet is denergized the springs g17 restore the parts to their normal position and permit the train to be operated until the detent-disk, with one of its notches, comes into line again with the stop. As the regulator energizes these circuits once every ve minutes, these operations will occur every five minutes and the hands or pointers on the annunciator be moved a five-minute step each time, or onetwelfth of its rotation, so that the local cil cuit, as hereinafter described, may be closed every five minutes and a signal or alarm given.

It may also be desirable to set the hands of the annunciator without interfering with the other mechanism. In order to accomplish this, I provide a central shaft I, which carries the minute hand or pointer II. Mounted upon the bearing for this shaft is a sleeve il, that carries a ratchet-wheel t" and which has an independent movement from the wheel 2, which is driven in any suitable manner so as to provide the relative rotation between the hour and the minute hands. This wheel,

which we will call the hourewheelf in that it controls the movement of the hour-hand, is provided with an arm c, which carries a click or dog 4, engaging with the ratchet-wheel- IIO As the hour-hand is mounted tightly upon the sleeve i' of the ratchet-wheel. it will be seen that it may be moved forward independent of the hour-wheel, but is prevented from being moved backward. At the same time the rotation of the hour-wheel is positively transmitted tothe hour-hand by means of the arm, dog, and ratchet-wheel above described. The minute-shaft is independently mounted and provided With the usual trici-ional spi-i ugs for transmitting power between it and the other portion of the train, which, however, is well understood by those skilled in the art.

In Fig. 1'.) I have shown a diagrammatic View of my combined mechanism, in which c is the rotating contact-shaft that makes and breaks the annunciator-circuits; C3, the rorating contact-collar for the battery-switch; A, the week-dial with its pins; H, the annunciator-magnet; 4, the contact-wheel on the annunciator; 5, the brush of the contactwheel 4; 6, the signalbell; G2, the hour-hand; G, the sliding contact ofthe annunciato r-dial, and 1, 2, and 3 the batteries. When the main circuit is closed and the motor has been started, the rotating contact-shaft in the posit-ion shown in Fig. 19 Will first strike the brush 010, so that the electric current will flow from battery 2 through the Wire E and its terminal to the rotating contact-collar E3, Wire lc, leading to the rotating contact-shaft c, brush 010, Wire 015, and Wire h to magnet H, energizing the magnet. The electric current will then pass through the magnet and return by the wire hand Wire d, spring-terminals a4 and d3, and wire d5 to battery 2. The magnet H of the annunciator being energized as above described draws down the pivoted armature-lever h2 and raises the arm or rod h3, throwing the tops Q12 out of engagement with the notched disk gu, permitting the notched disk to rotate in the direction indicated by the arrow on Fig. 19, so that the rotating disk 4 comes in contact with the brush 5 and closes the local circuit for the current Afrom the battery 7 t0 iiow through the bell 6 and sound the alarm, and from the bell the current flows through wire 8, hour-hand G2, brush g2, sliding contact g, wire 9, rotating disk 4, brush 5, and wire 10 back to the battery. The continued rotation of the parts 4 and g11 brings them into the relative position shown in the diagrammatic View of Fig. 19, and when so returned the local circuit is broken and the parts held from furtherrotation and in the relation shown in Fig. 19.
