i2 Claims. (CI. 58-19) Matter enclosed In heavy brackets II 1 appears in the original patent but forms no part of this rehsue My invention relates to alarm clocks and particulariy but not exclusively to improvements in electric alarm clocks.

Ordinary alarm clocks are equipped with bells or bumers which emit audible signals. Such clocks are of no value whatever to a person who is deaf and in many instances fail to'awaken persons of normal hearing unless the alarm is very loud. In any event, the suddenawakening o! a sleeper by a loud noise, such as the clamorous ringing of a bell, produces a distinct shock on the nervous system and, where other persons are sleeping in proximity to the alarm, they are also awakened. Y

The principal object of my invention is to, provide an alarm clock which will first give a visible alarm signal comprising an electric light and, in the event that said light fails to function, will, after the lapse of a predetermined interval following the time when said light should have begun to'function, give an audible signal. Another object is to provide such an alarm clock having means for effecting an intermittent flashing of the light alarm which many experiments have determined will invariably awaken a normal sleeper within an interval of from one to three minutes. A further object is to provide a, simple device of this character which may. beincorporated in any alarm clock but which is preferably associated with an electric alarm clock.

With these objects in view my invention ineludes the novel elements and the combinations and arrangements thereof described below and illustrated in the accompanying drawing in which- Fig. l is a front elevation view of an electric clock embodying my invention;

Fig. 2 is a fragmentary perspective view showing a portion of the side and rear of an electric clock mechanism and illustrating the controls for the visible and audible signals;

Fig. 3 is a fragmentary perspective view ofthe controls for the signals including a switch; certain parts which would obscure essential details of the control being omitted;

Fig. 4 is a diagram of the electric wiring; and

Fig. 5 is a more orflless schematic view of a thermostat element for alternately making and breaking the circuit through the visible signal to produce a flashing thereof.

Referring to the drawing---v i is the case of an electric clock having a sweep second hand 2, a minute hand '3 and an hour hand 4. The hour hand 4 carries a pointer 5 which indicates on the graduated disc 6 the time for which the alarm is set; it being understood that this disc may be turned independently of the clock hands by means of the alarm setting button I (see Fig. 2) which is understood to proiect through the back of the clock in the usual specification: matter printed In Italics indicates the additions made by reissue 2 way. The clock motor is a synchronous motor and preferably of the self starting type so that, in the event of a power interruption, the clock will start as soon as the power comes on. A small circular opening 8 is provided in the lace of the clock, and pivotally mounted behind this is a red disc 9 which becomes visible only upon an interruption oi the power to indicate that the clock has been stopped and that the time indicated thereby is not the correct time. Mounted on top of the clock is the visible signalling device l0, here shown as an ordinary incandescent lamp bulb which is mounted in the socket ll having the usual switch l2 for turning the light on or oil so that it may be used as a reading lamp if desired. However, it is to be understood that the lamp may be placed anywhere and that the switch l2 need not be associated with the lamp socket. In fact, if the lamp is to be used solely as a signal or alarm, the switch I! may be omitted.

Referring to Figs. 2 and 3, i3 represents generally the clock motor which comprises the coil I4, the pole pieces i5 and I6 and an armature enclosed in the casing i'l. One of the pole pieces it has an extension i8 which alternately attracts and releases the armature I! of a vibrating element 20 to produce a buzzing sound. when. the clock is in operation with the power on, a constant vibration of the element 20 would take place unless it were mechanically restrained and hence means, which will hereinafter be described, is provided, whereby vibration of the element 20 is prevented at all times when the alarm control is in the oil position.

2| is'the alarm gear which is driven by the clock motor and is to be understood as making one turn in [2 hours. Mounted upon the alarm gear shaft 22 is a cam 23 having a, notch 24 therein (see Fig. 3). [The cam 23 cooperates with. [normally engages] the extension 25 of .the armature portion IQ of the vibrating element 20, as a follower and prevents it from vibrating unof the clock is the ofi and on control forjth'e alarm. Thus, in the position of the bnttb "11,25 shown in Figs. 2 and 3 the alarm will as unded when the proper time is indicated byitheclock.

- In other words, the button 25 is shown in alarmon position. The button 26 is connected to the lever 21 which is slidably mounted in the clock frame members 28 and 25 and carries a cam 30 which is adapted to pass under and engage the end of the armature l9 when the button 26 is pushed inwardly, or to the left as shown in Fig.

3 and thus to maintain the armature 19in non- .vi brating position. The flat spring memberisl which is secured to the frame member 29,; as

in switch 42 which forces the 3 shown at 32. is provided with a spherical depression 38 therein which is designed to coop r with the opening 34 in the lever 21 to form a stop motion for the lever when it is pressed inwardly.

So far, the clock mechanism "which I have described is a standard mechanism forming part of almost all electric alarm clocks as now man-' ufactured. To this mechanism I propose to add my visible alarm signal and so to incorporate it with the audible alarm signal given by the element it that my. visible signal will first be given and then, after any predetermined interval to be fixed by the manufacturer of the clock. will be followed by the audible signal. To do this I fix a second cam 3| having a notch 35' therein tothe shaft 22 of the alarm gear II as shown in Figs. 2 and 3. Cooperating with the cam I! is a pawl or follower II which, as illustrated, is part of the bell crank 31 which is mounted to rotate freely on the shaft 38. The other arm 3! of the bell crank is provided with a threaded passage ll adapted to receive the adjusting screw ll. 42 is an electric switch of the single pole, doublethrow type having the terminals 0, 4t and I. The switch is adapted to be actuated by the push button it which is spring biased by meansof' the compression spring ll, shown schematically in Fig. 4, to maintain the terminal it normally in electrical contact with the terminal ll. However, when the button it is pressed against the compression of spring ll by means of thecoopwhich may be. and preferably is, a so called flasher "button which will begin, in effect, alternately to make and break the electrical circuit in whichit is installed within a few seconds alarm goes oil, the lamp is not lighted it will beeration of the adjusting screw Ii therewith, the

terminal 43 is held in electrical contact with th terminal.

Referring now to Fig. 4,4! and are main power lines to which the clock it may be connected by a plug and socket in the usual manner. Bearinginmindthattheterminalflis normally held in contact with the terminal 44 by means of the coaction of the follower [pawl] bell crank with the button ll, the light ll may be turned on oroif by means of the switch II. Thusitmaybeusedasareadinglamp.

Inoperation,thecam ll,insteadof thecam It. issocorrelatedwiththealarmsettingdiscl that if, for example, the 10th hour graduation onthediscissettocoincidewiththepointer I on the hour hand, the follower [pawl] II will fall into the notch 36' when the hands on the face of the clock indicate 10 o'clock. It is to be understood that the spring which normally forces the button 46 downwardly, as viewed in Pig. 3,

into the notch w itwillbeforced into this notchby the release of comprusion on the spring button 48 downwardly.

Now. referring more particularly to Fig. 4, when thefollower[pawl] flentersthenotchinthe cam ll, the bell crank will allow the button 0 to move to the right, as viewed in Fig. 4, thus breaking the contact between terminals 43 and 44 and establishing contact between the terminalllandtheterminaltl. Ifthelamp "were lighted at this time it would be momentarily extinguished by the breaking of its normal lighting circuit. However, the terminal 4| is simultaneomlyelectricallyconnectedtotbeterminalllof the lamp through the thermostatic element ll sin to flash within a few seconds after terininals It and are brought into contact.

In Fig. 5 I have shown in a diagrammatic manner how the thermostatic element ll operates. 55 and It are the terminals of the device. The terminal II is electrically connected to a fixed contact point 51 and is also connected to terminal 58 through the high resistance coil 58 which is wound about the bimetallic element 59 [39] carrying the contact point ll adapted to cooperate with contact 51. When the points are separated current flowing through the resistance heating coil it heats the bimetallic element 59 causing it to flex or warp and bring contacts BI and ill together. When this occurs, terminals 55 and it are directly connected through a resistance of negligible magnitude, the high resistance coil BI is shunted, and the bimetallic element to cools and assumes its original form, thus separating contacts I1 and 80. Current then flows only through the heating coil 58 and the cycle is repeated. It will be apparent that the circuit through the lamp and the thermostatic switch is never completely opened by the action of said switch because, when this circuit is otherwise closed by switch 42, current will always flow through the resistance heating coilll. However, the practical effect of theoperation' of the thermostatic switch, as evidenced by the flashing of lamp II, is the same as though the lamp circuit were alternately closed and opened, and I have referred throughout the specification and claims to the thermostatic switch as a circuit making and breaking means. The thermostatic switch does actually make and break the circuit which lights the lamp although another circuit of .very high resistance is immediately established through the lamp filament when the lighting circuit is broken.

Many tests have indicated that the flashing of the light II will awaken the average sleeper within an interval of three minutes or less. However, in the event that the lamp has burned out or has been removed from the socket, the cam which turns continuously in the direction of the arrow It will shortly release the audible alarm which will continue to function until the extension passes out of the notch 24 in cam 23. Obviously, the notches in the cams 2.3 and 35 may be disposed at any desired time interval apart so that the light signal may continue for any desired interval before the audible signal is released.

Unless some means were provided for preventing the follower [cam] 36 from dropping into the notch 35' in cam I! when the alarm control is in the off-position, the flashing signal would be given every 12 hours; the time depending upon the settin of the alarm. To prevent this I provide the bell crank 31 with an arm 53 which cooperates with a cam N on the alarm control lever 21 when said arm is pushed inwardly. Thus, when the button It is pushed in, the cam holds the vibrating armature II in inoperative position and the cam 54 cooperating with the arm It holds the follower [pawl] 38 in inoperative position.

From the foregoing it will be apparent that I have provided, by a rather simple modification of .the ordinary electric alarm clock, an alarm clock giving both a visible and an audible signal and while, as illustrated, the invention is shown as incorporated in an electrical clock, it may be incorporated in any alarm clock.

In addition to its utility asan ordinary alarm clock the device may be used as a desk or reading lamp, and when so used it may be set to give a flashing signal at any desired time. It makes no difference whether the lamp I is lighted or out at the time the signal is given because, the light control switch II is automatically shunted and a new circuit established through the lamp.

The device, whether it be used as an alarm for awakenin a sleeper, an appointment signal, or

otherwise should prove aboon to persons who are v nervous and detest noiseot any kind.

By the term electric clock" as used in the claims, I mean to include only clocks in which the timing mechanism is actuated by a synchronous motor.

While I have described my invention in its preferred embodiment it is to be understood that the words which I have used are words of description rather than of limitation and that changes within the purview of the appended'claims may be made without departing from the true scope and spirit of my invention.
