Application October 23, 1946, Serial No. 705,068

11 Claims. 1

My invention relates to signaling devices and particularly to devices of this character for awakening people at any predetermined time.

In my co-pending application, Serial No. 613,070, now U. S. Letters Patent No. 2,444,748, I have disclosed an alarm clock, specifically an electric alarm clock, by means of which two signals of different character are given in sequence. The first signal is the flashing of an electric lamp which may continue for any desired interval and which, if the lamp is burned out or any other defect prevents the giving of this first signal, is supplemented by an audible signal such as a buzzer.

The present invention relates to a signaling device in which the first signal given is a visible signal, as by the flashing of a lamp, and the second signal is given from a loud speaker of a radio, and in which the means for controlling these signals is of somewhat different character than that disclosed in 'my co-pending application aforesaid.

One of the objects of my invention is to provide a radio receiving device combined with a clock by means of which the timing of the signaling means is controlled. Another object is to provide a cabinet in which is combined a radio receiving means and a clock, and to which any available electric lamp maybe connected by simply plugging the lamp wires into a receptacle in said cabinet. Another object is to provide a device of this character in which the radio may be used at any time independently of the signaling apparatus. Another object is to provide a device in which a table or other lamp may be connected thereto and which may be utilized to give the flashing signal, and also used at any time, except when the signaling apparatus is in actual operation, as a reading lamp independently of the signaling apparatus. Another object is to provide a signaling device comprising a radio receiving set for giving an audible signal and a. lamp for giving a visible signal and means for controlling the operation of these signals in timed relation to each other. With these objects in view, my invention includes the novel elements and the combinations and arrangements thereof described .below and illustrated in the accompanying drawings in which- Fig. 1 is a front elevation view of my device;

Fig. 2 is a rear view of the device drawn to a substantially smaller scale;

Fig. 3 is a fragmentary perspective view of a portion of an electric clock with certain portions omitted and certain portions broken away in order clearly to show the particular parts thereof and the parts associated therewith which are pertinent to my invention;

Fig. 4 is a wiring diagram including, in a more or less diagrammatic manner, those portions of the clock mechanism which control the operation of the signaling circuits;

Fig. 5 and Fig. 6 show the relative positions of the contact fingers in closing the circuits for the first and second signals respectively; and

Fig. '7 is a fragmentary wiring diagram similar to Fig. 4 but illustrating a modification of the lighting circuit.

Referring to the drawings, my device comprises a cabinet I containing a radio receiving set which may be turned on and off by means of the switch 2 and tuned by means of the knob 3 which moves the index 4 over the dial 5 which may be graduated in kilocycles, as well understood in the art, to indicate the frequency to which the set is tuned. 6 is the opening of a loud speaker, understood to be in the cabinet but not shown. I is an electric clock having a hand 8 which may be turned by the knob 9 to indicate the time at which the signal will be given. Ill is a knob for turning the alarm on or off and II is a table lamp, actuated by pulling the switch cord l2, and which may be plugged into the socket or outlet IS on the back of the radio cabinet. As illustrated in Fig. 4, the outlet l3 would have three terminals and a three wire conductor would be required to connect the lamp II with the circuits in the cabinet in order to by-pass switch 12 when the alarm goes into operation and insure a positive operation of the lamp signal ll irrespective of the position of switch [2. Projecting from the back of the cabinet I is a button It by turning which the hands of the clock may be set to the correct time. Also extending from the back of the cabinet I is the electrical conductor l5 having the usual plug IS on the end thereof which may be inserted in any convenient outlet for connecting both the clock and the radio to a source of power.

Referring now more particularly to Fig. 3, I1 is the back of the face of the clock. I 8 is a wide faced clock gear which is directly connected to the hour hand and which, therefore, makes one complete rotation every 12 hours. I9 is a narrow faced gear of the same diameter as the gear I! and in mesh therewith so that it also makes one complete rotation in 12 hours. 20 is a gear which is connected to the spindle or shaft carrying the alarm setting hand 8 (see Fig. 1). In mesh with the gear 20 is the gear 2| which is in mesh with the spur gear 22 on a shaft 23 which may be turned through suitable gearing (not shown) by turning the button 9 to set the alarm at the desired time. The gear wheel 2| is provided with an arcuate slot 25 therein which cooperates with a cam 26 on the rear side of the wheel I9. Since the wheel l8 revolves in the direction of the arrow shown thereon the wheel IS, in mesh therewith, revolves in the direction of the arrow shown on that wheel. The wheel i9 is coaxial with the wheel 2| and rides freely on its shaft l9 so that it may move toward and away from the wheel 2| and still remain in mesh with the wheel l8; the face of the wheel l8 being of substantial width to permit the aforesaid axial movements of the wheel i9 while maintaining it in mesh with the wheel l8. The cam 26 on that face of wheel l9 which is adjacent wheel 2| is providedwith two steps 21 and 28 positioned to drop in the slot 25 in the wheel 2|. The high point of the cam 26 normally rides in contact with the side of the gear 2| and the wheel |9 carrying cam 25 is nor mally urged towards wheel 2| by the lever 29, which is-mounted on shaft 30, and the light helical spring 3| which is biased to hold the lever 29 in contact with the hub 32 on wheel l9.

From the foregoing, it will be apparent that the gears 29 and 2| are normally stationary except when the alarm is being set byturning the setting button 9. 7

It will be also apparent that, since the gea l9 makes one turn in every 12 hours, the cam 26 will be forced into the slot 25 once in every 12 hours. First the step 2' I will drop into the slot 25 and, as the wheel l9 continues to rotate, step 23 will drop into the slot. As the wheel I9 continues to rotate, the cam 25 will be forced out of the slot and pushes the wheel l9 back to its normal position by the cooperation of the curved cam-like surface 33 with the end of the slot.

The wheels l9 and 2| with the slot 25 and cam 26 are also shown in Figs. 4, and 6 in a more or less diagrammatic manner but, before passing to a detailed description of these last mentioned figures, it might be well to point out that, in Fig. 3 an armature or buzzer 34 having a clapper 35 associated therewith and adapted to strike the gong 36 is shown and may be used if desired. The armature 34 is always energized when the clock mechanism is connected to a source of power and, unless restrained, would vibrate continuously. It is normally held inoperative by means of the push-pull button 31 which projects through the back of the casing or cabinet I and has a projection 38 thereon which cooperates with the armature 34, when the button 31 is pushed in, to prevent vibration thereof. The armature is also restrained by the projection 38 on the lever 29 when in the position shown in Fig. 3. However, when the button 31 is pulled out, the armature or buzzer is then held inoperative only by the projection 38 on lever 29 so that, whenthe cam 26 drops into the slot 25 in wheel 2|, as wheel i9 is moved towards wheel 2| by the lever 25 and spring 3|, projection 38' moves away from the end of armature 34 and the armature automatically begins to vibrate and emit a. buzzing sound or ring the gong if provided with the clapper 35.

Referring to Fig. 4 in connection with Fig. 3, it will be noted that a resilient finger 39 is provided with a button 49 of fibre or other insulating material which bears against the side of gear l9 which carries the cam 26. The finger 39 is m unt d w th fin e s 42. 43. and 44 on the back of the face H of the clock as shown in Fig.

4. Each of these fingers is electrically insulated.

from each of the other fingers by means of the insulating blocks 45 therebetween-and the insulating bushings 43 through which the means 41 for securing them together pass. The resilient flnger 39 is provided with contacts 43 and 49 on opposite sides thereof the finger 4| is provided with a contact 56 adapted to cooperate with the contact 48 on finger 39; the finger 42 is provided with a contact 5| adapted to cooperate with the contact 49 and, on the other side thereof, with a contact 52 adapted to cooperate with the contact 53 on the finger 43; 43 in turn being provided on the other side thereof with a contact 54 adapted to cooperate with the contact 55 on finger 44.

Normally, the gears I9 and 2| and the resilient fingers are in position shown in Fig. 4, while Fig. 5 shows the position of the fingers when the cam 28 has moved its first step into slot 25 in wheel 2|, and Fig. 6 shows the position of the resilient fingers when cam 26 has moved its second step intothe slot 25.

In Fig. 4, 56 and 51 are the main power lines to which the terminals 58 and 59 of the signaling device are connected when the plug i6 is inserted in a convenient outlet. 60 is the radio which is provided with the switch 2 for turning it oil and on and the tuning means 3 which is regulated by the knob 3, shown in Fig. 1. It will be apparent that, by closing the switch 2, the radio 69 may be. connected directly to the power lines 56 and 51. Thus, by closing or openin the switch 2, the radio may be operated at any time independently of the signaling mechanism. l I is a table lamp, one terminal of which, when the lamp is plugged into the outlet I3, is connected permanently to the power line 56, and the other terminal may be connected with the other power line 51 by closing the switch 12 which closes a circuit through the conductors GI and 62, and

switch l0 which is a double pole, double throw switch, or its equivalent, for closing and opening the circuits, as shown in Fig. 4. It will be apparent from the foregoing that the lamp ll may be used at any time in a normal manner when the switch I9 is in either the alarm oil or the alarm on position.

When the alarm is set at the desired hour, the switch I0 may be moved to the alarm on position, but this does not in any way, so long as the alarm is not in actual operation, interfere with I the normal use of the radio or the lamp ll. Thus, the lamp may be turned oil and on by means of the switch l2 although a somewhat different circuit is used when the switch I0 is in the on position than when it is in the off position. When the switch I9 is in the on position, the circuit through the lamp is through switch I2, conductor 6|, finger 4|, through the contacts 48 and 50, finger 39, conductor 64, switch l0 and conductor 63 to the main power line 51. Obviously, the movement of the switch ID to the alarm on position does not in any. way affect the operation of the switch 2 to turn the radio off and on.

Ordinarily, upon retiring, the table lamp switch would be turned to the off, position to extinguish the light but, whether or not it is extinguished, it will begin to flash, as will be described below, when the first step of cam 25 drops into slot 25. When this occurs at the appointed hour, and the switch it is in the alarm on position, the fingers are as shown in Fig. 5 and a circuit through the lamp i is established as follows:

The connection between contacts 68 and 59 is broken and a connection is established between contacts 49 and 5|, as shown in Fig. 5, thus the auam , circuit through the lamp control switch I! is opened and switch I2 is by-passed. Starting with power line 55 adjacent the lamp II, the current flows through the lamp. conductor 35, switch I3, conductors 55 and 51 through the coil 55 which surrounds the bimetallic element 59 in the thermostatic switch 10, and thence through conductor 1|, finger 42, contacts 49 and 5|, finger 39, conductor 54, switch It and conductor 53 to power line 51. When the thermostatic switch 13 is in this position the light H is not lighted because suflicient current is not flowing through the above circuit due to the high resistance of the coil 59 in the thermostatic switch. However, the

vcurrent flowing through the coil 59 heats the thermostat element 59 causing it to warp upwardly and close the contact points so that a circuit between lamp I is then established through conductor 55, the short leg 12 of switch ill, conductors 55 and 51, the contacts of switch 19, directly through the thermostat element 59, conductor 1|, finger 42, contacts 49 and 5|, conductor 54, the long leg 19 of the switch I5 andconductor 53 to power line 51; and the lamp is thus lighted.

However, the closing of the contact points of switch 15 shunts the heating coil 53 around the thermostat element 59 which causes the element 53 to cool and flex so that the switch is opened whereupon the cycle 1.; repeated. Thus, an intermittent flashing of the lamp continues so long as the last mentioned circuits are maintained. While the thermostatic element does not entirely break the circuit through the lamp, since some small amount of current is always flowing through the high resistance coil 55, it does, in efiect, break the lighting circuit insofar as the illumination of the lamp is concerned, and I have therefore referred to its function as that of making and breaking an electrical circuit.

When the second notch or step of the cam 25 drops into the slot 25 the fingers are then in the position shown in Fig. 6. In this position fingers 39, 42, 43 and 44 are all electrically connected together with the following result:

When finger 44 is electrically connected, as in Fig. 6, to finger 39, a new circuit is established through the lamp II which by-passes thermostatic switch 10 and connects lamp directly to the power lines so that an uninterrupted lighting of said lamp occurs. Thus, starting from the power line 55 adjacent lamp II, current flows through lamp conductor 55, the short leg 12 of switch It, conductors 55 and 14, finger 44 through contacts 55, 54, 53, 52, 5| and 49 to finger 33, thence through conductor 54 through the long leg 13 of switch iii and conductor 53 to power line 51.

Simultaneously with the uninterrupted illumination of lamp Ii, another circuit is established through the radio receiver 50 as follows:

Starting at the point where conductor 15 contacts power line 55, current flows through the conductor 15 through the radio receiver 53, through the conductor 15 which by-passes radio control switch 2 to finger 43, thence through contacts 53, 52, 5| and 49 to finger 39 which is connected to conductor 54, thence through conductor 54 and the long leg 13 of switch Ill through conductor 53 to power line 51. Thus, ii. the radio receiver is tuned to receive a program or signals from a certain station, the program or signals will be heard through the loud speaker of the receiver.

If the device is used as an alarm clock, the

6 oil by moving the switch III to the of! position whereupon the light Il may be controlled by means oi! the switch I2. Should it happen that the signaling means has been set for operation and no one is present to shut oil the signal by moving switch III as aforesaid, the cam 25, due to the rounded face 11 thereon will, in a short time, ride out oi the slot 25 and restore the parts to their normal position shown in Fig. 4, thus automatically shunting oil! the signals.

With the arrangement as illustrated and described in connection with Fig. 4, a three-wire cable is required it the lamp I is to be controlled by a switch |2 thereon because it is necessary to have two separate circuits, having one common wire leading to the lamp so that it is'possible both to control the lamp through the switch I2 and also to control the lamp H by means of a circuit which by-passes switch l2.

Where an ordinary two-wire cableis used to connect lamp II to an outlet I3 in the casing I,

a minor change in the lamp circuit is required as shown in Fig. 7, and it is also desirable to provide the switch Ill with a neutral or "off position. The only change required in the circuit is to elimlnate the switch l2 and to connect the conductor 5| to the conductor as shown at 18 in Fig. 'I. With this circuit the lamp may be lighted by turning the switch ID to the "light position so that a circuit is formed from power line 55 through the lamp, conductor 5|, conductor 52, the long leg 13 of switch lliand conductor 53 to power line 51. To extinguish lamp II, switch I0 is merely turned to the oil position.

When the fingers are in the position shown in Fig. 4 and the switch It in Fig. '1 is in the alarm on position, no current is flowing through the conductor because one of the current paths leading from conductor 55 is through conductor 14 to finger 44 where it terminates, and the other path is from conductor 55 through conductor 51, heating coil 59 on thermostatic switch 10 and through conductor 1| to finger 42 where it ends. However, when the first notch of cam 25 drops into the slot 25, thus connecting finger 42 with finger 39, a circuit through lamp I and through the thermostatic switch, which causes an intermittent flashing of lamp II, is established as described above: When the second step of cam 25 drops into slot 25, thus arranging the switch fingers as illustrated in Fig. 6, the radio receiver is connected to the power lines and the lamp II is connected directly to the power lines to produce an uninterrupted lighting thereof, as described above.

From the foregoing, it will be apparent that the lamp alone may be used as a signal by merely tuning the radio receiver so that no signal is received therefrom when said receiver is connected to the power lines. Furthermore, the radio receiver may be used alone as a signal by merely removing the lamp II from its socket; the buzzer or gong may be used alone in place of the lamp, or with the lamp or the radio, or with both.

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 in its broader aspects.
