ALARM-CLOCK.

Specification of Letters Patent.

Patented June 9, 1908.

Application filed. larch 16, 1808. Serial No. 421,858.

To all whom it may concern:

Be it known that I, VALERE S. GAILLARD, a citizen of the United States, residing at Torrington, in the county of Litchfield and State of Connecticut, have invented certain new and useful Im rovements in Alarm-Clocks, of which the fo lowing is a specification.

The object of my invention is to provide an alarm clock which, instead of giving an alarm lasting some minutes or several seconds by repeatedly ringing a bell -will give the alarm by a single short sound as b the strik ing of a bell once only. This is esirable in many instances and for various reasons. For example, in a sick room it is often desirable to be reminded at definitely prescribed intervals when a dose of medicine should be administered, but it is also desirable that the patient should not be disturbed by the repeated sounding of an alarm. I The batteryshould not be drawn on too heavily, as would be required if the alarm were sounded for any great length of time.

According to my invention I provide certain attachments to, a clock of ordinary construction by which .the objects of my invention may be accomplished. Such clock need not be an alarm clock of the usual kind operated by a spring, but I can apply my im-' provements to an ordinary alarm clock so that when desired such-clock may be used in the usual way, or my improved'alarm mechanism. may be used independently thereof.

In connection with my improved alarm mechanism I may use an electric lamp which may flash when the alarm is sounded, or it may be used for a longer period if desired.

In carrying out my invention I attach to the hour hand arbor of the clock a pin-carrying wheel which is adapted to operate a system of levers, one of which is connected with one pole of a battery and which is adapted to make electrical connection with a contact connected with the other pole of the battery. The pin-carrying wheel revolves once in twelve hours and the ins are so set as to operate the alarm mec anism at the desired intervals. An electric lamp is arranged in the circuit of the alarm mechanism so as to flash when the alarm is sounded and it is also separately connected with the battery so that it may be used for a longer intervalif desired.

In the accompanying drawings,Figure 1 is a perspective view of a clock with my improved alarm mechanism connected therewlth. Fig. 2 1s a view partly in side elevation and partly invertical section of the clock and alarm mechanism indicated in Fig. 1. Fig. 3 shows a vertical central section through the pin-car 'ng wheel. Fig. 4 .is a view partly in rear e evation and partly in vertica section with some of the parts broken away of the mechanism shown in Figs. 1 and 2. Fig. 5 is a detail view in section of certain contact devices. Fig. -6 is a rear elevation on a smaller scale indicating how the pins may be set for'operating the alarm.

' The clock A may be of any usual kind.

As shown it is an ordinary alarm clock and may whenever desired be used as such.

a indicates the handle for winding the alarm mechanism, a the handle for winding the clock movement, a the alarm setting devices, and a the regulating devices. Any other ordinary time-keeper without alarm mechanism may be used just as well.

To the rear end of the arbor of the hour pin-carryin wheel. It is preferably constructed wit a central huh I) attached to'said arbor and has two radial spokes b on op 0- site sides of the hub supporting a rim pre erably made, as shown most clearly in Fig. 3, of three circular layers of wood or other suitable material, the central layer 0 being of smaller diameter than the other layers 0, thus leaving an annular space or groove 0 between the layers c, 0 p

The rim is provided with two annular con- /centric series of pin holes at, m, the outer series a; being for the purpose of holding the pins in o erative position, while the inner series a." hol' reserve pins. The outer series of holes a: are arranged outside the periphery of the layer 0, so that when a pin is inserted in a hole of the outer series, it will bridge the groove 0 The holes a; are 1placed to correspond with the dial of the 0100 and may be arranged at bor of any ordinary clock, taking the place of hand is attached a wheel B, which I call the G may be located at any suitable art oft e box or 0: 1g as may a so the bell H indicates a small electric lamp placed on the top of the casing in front of the clock face and connected by a wire h with one pole of the battery G and by a ,wire h with the contact 5 of a switch I, which latter is connected by a wire '5 with the other pole of the battery. If the switch is made to engage the contact 4., the lamp will be lighted, but it is not my intention that the lamp should be lighted for any considerable time as this would soon exhaust the battery. The switch and the circuit connections described will, however, enable one to light the lamp for a short time to allow the clock dial to be inspected without sounding an alarm.

In the rear part of the casing E is a false back J to which are pivoted two vertically arranged levers, K and L. The lever K 18 pivoted at k a comparatively short distance elow its u per end and the upper gprtion of the lever a ove the pivot extends t ough an opening f in the casing and projects into the groove 0 of the pin-carryin wheel. A portion of the lever X below t e in k extends down across the rear face of t e false back and at its lower end is slotted at k where it engages a pin 1 carried by the contact lever L ivotedat its lower end by a pin 1 to the alse back and extending u from the in Z for a considerable distance, eing provi ed at its extreme upper end with a contact roller l Normally the levers are in the position shown in Fig. 4 with the contact lever resting against a stop m, but when the upper end of the lever K is moved to the right, the upper end of the lever L will be thrown over to the left against the stop m. In order to return the levers quickly to their normal position I rovide a spring M arranged on the pivot pin of the lever L and secured to the false back and to the-lever in any suitable way.

The pivot pin 1 is connected by means of the wire n with the electro-magnets of the sulated wire, as shown in Fig. 5, the bared end being passed through the false back J, bent down at right angles and secured in place by a staple, as indicated.

In order that the sound of the bell may not be deadened by the casing I preferably provide the latter with perforations or openings as indicated at Z.

If no pins are arranged in any of the holes 2:, the pin-carrying wheel will revolve without sounding an alarm, but if one pin is arranged in a hole a: the alarm will be sounded once in twelve hours, or as soon as the pin wherever set comes-in contact with the lever K. By placing pins at any desired intervals of time, the alarm may be sounded at each of such intervals, for instance, as indicated in Fig. 4, if there is only one pin set at six, the alarm will be sounded at six oclock only. In Fig. 6 ins are set at 1, 3, 5, and 7, and the alarm be sounded during such eriods every two hours apart. It is obvlous that the pins may be set to sound the alarm at any desired time, or at any desired intervals. Thus where a doctor prescribes medicine to be given to a patient at intervals of two hours, the attending nurse, by means of my improvements, may be reminded at such intervals to administer the medicine either during the night or durin the day, while the alarm will sound for sue a short eriod and may be arranged to sound so faintly as to merely attract the attention of the nurse without disturbing the patient. The mechanism may, of course, be used for other purposes and in other connections to call attention to the la se of various intervals of time.

A very sli ht movement given to theupper end of t e lever K will cause the lower end thereof to make a comparativelylong movement and a much lon er and quicker movement will be given to t e u per end of the lever L. The movement 0 the upper end of the lever L is, however, sufficiently slow to allow the contact between the roller 1 and the contact 0 to be made lon enough to complete the circuit and sound t e alarm once without allowing the bell to repeatedly ring. After the lever K is disengaged from the pin the sprin M moves the levers guickly back to their normal position and in oing this the roller 1 passes so rapidly over the contact 0 that the electric circuit is not made long enough to ring the bell. The electric lamp, as hereinbefore described, may

be made to flash each time that the alarm 1s operate a visible signal which will'attract attention without making any sound and if preferred, the lamp H may be given some distinctive color, such as red. The bell F may, of course, be sowired as to make and break the circuit rapidly as long as the contact-arm L is on the contact 0, or it ma be wired so as to ring once only, no matter ow long the circuit is closed. These two kinds of bell are well known. If the contact 0 is made longer or any other means is adopted for prolonging 'the closed circuit the bell may be caused to give a single sound while the lamp is lighted for a considerable time so that after the audible signal is given the clock face will be illuminated long enou h to enable one to ascertain the time. After the time is ascertained the circuit may be broken by means of the switch P and by means of this switch the apparatus may be converted from a combined audible and visible signal to one which is visible only.

I have shown and described the way now best known to me of carrying out my invention but it is obvious that the details of construction may be chan ed or considerably re-or anized without eparting from the nove features of my lmprovements.
