ALARM-CLOCK.

Specification of Letters Patent.

Patented Aug. 10, 1999.

Application led. February 24, 1909. 'Serial No. 479,747.

To all whom it may concern:

Be it known that l, Josnrn B. OoNNoLLY, a citizen of the United. States, residing at ldlashington, in the District of Columbia, have invented certain new and useful lmprovements in Alarm-Clocks, of which the following is a specitication.

rThis invention has relation to alarm clocks and has for its object the provision of novel means for giving an audible signal at anyk predetermined time, as is customary With alarm clocks ot the usual character, and also for visually indicating the particular purpose for which the alarm has been caused to sound at a particular time.

A further object of the invention is to provide novel means whereby the alarm actuating and alarm setting devices are simultaneously operated by the manual movement of a single actuating p art, such as a lever or Wheel operatively connected to the alarm actuating and the alarm setting devices.

in carrying my invention into effect, l preferably employ an alarm `clock ot Well knot/'n construction having the usual parts and apply thereto the mechanism hereinafter described in detail and adapted to accomplish the objects of this invention.

As the construction and operation of alarm clocks ot the ordinary character are Well understood will not specifically describe all the parts of the same, but ceniine the description of the clock to such parts as coact with my present improvements, and specifically describe the latter.

in the accompanying drawing: Figure 1 is a side elevation of an alarm clock With my improvements applied thereto. Fig. 2 isa front elevation of the clock shown in Fig. 1. Fig. 3 is a front elevation of a clock of modiiied construction also embodying my impiovements. Fig. 4 is a rear elevation ot the clock shown in Fig. 3. Fig. 5 is a fragmentary sectional view on an enlarged scale of a portion et the mechanism common to both of the clocks shown in the other figures. Fig. 6 is a perspective view of a modiiied form of memorandum tablet to be used with the clock shown in Figs. 1 and 2. 7 is a plan view ot the clock with the dial and case removed. Fig. 8 is a front elevation of the same with the case, the dial and the hands removed.

The clock Works are contained in a casing 1 supported by legs 2 and having the dial 3 the hour ,hand 4, minute hand 5, seconds hand 6.

An alarm bell 7 is mounted. on casing 1 and the hour hand arbor S is provided on its rear end with the usual button or thumb-nut 9 ior setting the hands, While the shaft 10 of the main spring is provided with a key 11, and the time keeping mechanism is operably connected with the alarm let-ott' mechanism in the usual manner and as shown in Figs. 7 and 8, all these parts being ofthe usual or any desired construction.

Upon the back of the clock a hollow boss 12 is mounted and secured, this boss having a central opening through which thc hour hand sha'l't or arbor 3 passes loosely, and upon this boss is loosely mounted a gear Wheel 13 which carries an arm 14 that is attached to the Wheel 13 and is bent around the side of the clock and terminates at the iront Oi the clock Where it carries a hand or pointer 15 adapted to point to the figures at the edge of the dial. A nut 16 serves to sustain the Wheel 13 at its proper position on the boss While permitting it to be turned freely thereon through the medium oi arm 14. The gear Wheel 13 meshes with an idler 17 mounted on the back ot' the clock and said idler 17 meshes With a gear Wheel 18, carried on and rigidly attached to the alarm setting shaft 1Q, the Cear Wheels 13 and 18 being of exactly the same diameter so that the Wheel 13 will complete a revolution at each complete revolution oi' the wheel13, and Will, o1' course, make a partial revolution oi' equal extent With each partial revolution of Wheel 13. A third gear Wheel 2O is rigidly attached to the alarm Winding sha'lt 21, and meshes With the idler 17 the Wheel 2O being oi any desired size relatively to the Wheel 13. The alarm operating mechanism of which the sha'lt 21 is a part, is so constructed that the shal't 21 is permitted to turn in one direction only and does not rotate reversely to the Winding movement when the alarm goes oli', but as this is a common and Well known construction, the alarm mechanism need not be more particularly described.

In Figs. 1 and 2 o'l` the drawing a small plate or tablet 22 is carried by the arm 14, this tablet being made of some material that will readily receive slate pencil, lead pencil, or other marks that can be easily erased, such material, for instance, as slate, ground glass, or roughened celluloid or the like. The tablet is supported in a frame 23 which is attached to the arm 14 by clips 24 so that the frame and tablet can be readily removed and replaced when it is desired to write on the tablet or erase the writing from the same.

In the modii'ied form shown in Fig. 3 of the drawing the plate or tablet 22 is dispensed with and instead of the same I provide a stationary annular writing surface 25 which surrounds and partially covers the numerals on the dial and which can be easily formed by roughening or grinding the outer portion of the glass face which usually covers the dial, although I prefer to make this writing surface of somewhat larger diameter than the dial so as to give ample writing space to receive the desired memoranda.

In the modified form ol" memorandum tablet shown in Fig. 6 a block or pad of sheets ol' paper 26 is secured to a backing 27 and the latter is provided with spring clips 28 by means of which the tablet can be readily attached to the arm 14. Each sheet can bear numbers indicating the day of the month and each sheet after being used can be torn off and preserved thus serving as a record of the days engagements.

rPhe alarm winding and setting mechanism of the clock shown in Figs. 1 and 2 is exactly the same as that of the clock shown in Figs. 3 and 4, such mechanism being illustrated in Figs. a and 5 and having been hereinbefore described.

The operation is as follows: 'The memoranda of various matters requiring attention at particular times is written either on the tablet 22 or on the surface 25 or on one of the sheets of the block or pad 26, and the arm 14 is moved from right to left, that is in a reverse direction to the movement of the hands of the clock until the hand or pointer 15 points to the hour and minute of the iirst memorandum. Vlfhen the hour hand reaches a point opposite the hand or pointer 15, the alarm wil be sounded and a glance at the tablet 22 or he Writing surface 25 or the outer sheet or pad 26 will show what particular matter requires attention. After the alarm has gone off the arm 14 is moved in the direction of the arrow until the hand or pointer 15 points to another hour, this movement simultaneously winding an d setting the alarm and thus making ready for the sounding of the alarm Without further attention or manipulation. The arm 14, it is to be noted, is always moved in a direction opposite to the movement of the hands, and thus if, for instance, the rst alarm soun ds at two oclock and it is desired to have the next alarm sound at three oclock, the arm 1d is turned through eleven twelfths of a circle, thus bringing the hand or pointer 15 opposite the numeral III on the dial.

I claim:

1. rlhe combination with an alarm clock,

of a movable arm connected to and adapted to simultaneously operate the alarm winding and alarm setting mechanism and a memcrandum tablet carried by said arm.

2. rIhe combination with an alarm clock, of a movable arm having a pointer adapted to successively point to the figures on the dial of the clock, and a memorandum tablet carried by said arm.

3. rIhe combination in an alarm clock of time keeping mechanism and time indicating means for keeping an d indicating the time of day and alarm mechanism adapted to be let off by the progressive and uninterrupted movement of the time keeping mechanism, with a movable arm and means controlled by the movement of said arm for simultaneously winding and setting the alarm mechanism.

li. In an alarm clock embodying time keeping mechanism and time indicating means adapted to keep and indicate the time of day and alarm mechanism adapted to be let oli' by the progressive and uninterrupted movement of the time keeping mechanism, said alarm mechanism including the alarm operating and alarm setting mechanism, and means for simultaneously Winding and setting the alarm.

5. In an alarm clock embodying time keepingv mechanism and time indicating means for keeping and indicating the time of day and. alarm mechanism adapted to be let olf by the time keeping mechanism while the latter continues in operation, said alarm mechanism including the alarm operating and alarm setting mechanisms, means for simultaneously winding and setting the alarm and a pointer adapted to indicate the time at which the alarm will sound.

6. In an alarm clock embodying time keeping mechanism and alarm mechanism adapted to be let olf by the time keeping mechanism, the combination with the dial and a movable pointer to indicate the time at which the alarm will sound, of a memorandum tablet carried by the clock arranger in proximity to the dial of the clock.

7. T ie combination with time keeping mechanism and time indicating means adapted to keep and indicate the time of day and alarm mechanism adapted to be let olf y the progressive uninterrupted movement of the time keeping mech sin, oi' means whereby the actuating spring of the alarm mechanism will be wound by the movement of the alarm setting mechanism.

In testimony whereof I have a'fl'lxed my signature, in presence of two witnesses.
