REMINDER-CLOCK.

Specification of Letters Patent.

Patented July 17, 1917.

Application filed June 26, 1916. Serial No. 106,031.

To all whom it may concern Be it known that I, AUGUSTA Y. DAROHE, a citizen of the United States, residing at Chicago, in the county ofCook and State of Illinois, have invented certain new and useful Improvements in Reminder-Clocks; and

I do hereby declare the following to be a clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. i

This invention relates to time controlling especially to annunciators having anadjustable pin; and one object of the same is to produce a reminder clocl; whose hour hand arbor carries a contact arm adapted close a circuit through an alarm by coming in contact with a pin selectively set by the operator when the alarm is desired.

Another object is ments in the structure of the contact and in ment at quarter-hour intervals.

other object is to produce improvements in means for insulating the dial from the remainder of the clock.

With these ob'ects in view the invention consists in the etails' described below and shown in the drawings wherein Figurel is a front elevation of this clock with most of the dial and its retaining ring and both'of the hands removed.-

Fig. 2 is a central vertical-section.

Fig. 3 is an enlarged; front elevation of contact arm, and Fig. 4* is a perspective the rear. In the accompanying drawings I have invention as applied'to a clock which may be of any suitable t adaptedto actuate an alarm WhlCh is herewithin the frame of the clock but which may also be of an suitable type and location. 7 A limited in these part'culars, and I have'used reference letters for those elements which 'is to form no part of the present inventiom That say the frame F carries the clock mechanism C ting access to setting, etc. 1 The frame F also other door D givin containing a source 0 has anelectricity E such as a mechanism such as 'a bell B The frame F ma also'have a seriesof sockets S for pins whose useis dewithin the upper portion to produce improve-. v

r and of. course also the means for giving it a step by step move- 3 of the ype, and is.

.I do not WlSh to be and has a rear door D permit v said mechanism for winding,"-

access to a chamberwhee 22 h scribed below. This specification is not concerned with the structure of the clock ex cepting its hour hand H and the arbor A thereo j 6 The clock C is here shown as attached by screws 1 to a plate 2 which is fitted nicely of the frame F, has an annular shoulder3, and a forwardly projecting flange 4 surroundin it. The glass 5 5 is carried within a circular i rame 6 which has a rcanwardly projecting flange 7 inclosing said flange land removably attached thereto by suitable means such as screws 8, and this frame has through it forty-eight holes 9 disposed one opposite each number on the dial or opposite the even hours, and three between each two members so as to be oppositethe quarter hours. One side of the attery E isconnected by a wire 10 with the clock G, and therefore it is in electric connection with the plate 2 and frame 6, with the arbor A and 'ever, is so arated from the frame 6 by the glass 5.

sheet 14 0f insulation is placed behind the dial so that it cannot come into contact with any other mechanism: It is held in place by screws 15 as best seen in Fig. l, and these pass through a ring, 18 of insulation between the dial and the'shoulder plate 2, and extend into the frame F which will probably be of wood, so that as' a result the dial is entirely insulated. Around its periphery it is provided with holes 19 registering with those numbered 9 inthe frame 6, but somewhat smaller. The'pins P have insulated bodiesl6 and bare tips 17,

'the'latter being of a size to pass into the rholes' .19 and throu h them, whereas the insulated bpdies project" for some distance are 0 a size to rest in the holes 9 but the pins will be out of metalllccontact with the frame 6 and any portion of the clock mechanism. When the pins are not being used they are laeedin the sockets S as seen in Fig. 2. 1% wire 20 leads from the battery E to'ther alarm B in the frame F, and is connected'with the dial 11 whichwith any pinor pins in ustherefore becomes one terminal. Ri 'dly carried by the plate2 is a ratchet aving forty-eight teeth facing in the direction best seen in Fig. 3 which is to V the left or the. reverse of the direction which the hands move. The arbor A of the hour hand carries the contact hand or arm which, as seen in Fig. 2, stands between the front plate 2 of the clock and the dial 11, or

between said plate and the sheetof insula-.

tion 14, and therefore it is not only out of sight but is housed behind the dial and ina chamber Where it can touch nothing but a the tips, of such pins as are in use. Said contact hand or arm is of metal and comprises a body 21 enlarged at its inner end into a r ng 23 behlnd which is a hub 24, and behind the hub in turn is another ring 25 carrying a short arm or stub 26 standingabout in alinement with the body and on the opposite side of the hub 24 therefrom.

. In the outer end of said stub is formed a notch 27 whose bottom is inclined, or eccenwhich carries a pin 37 projecting to the rear into the notch 27 A contractile spring 38 connects the finger with the outer end of the body 21 and draws the former normally outward on said body so as to hold the pin in contact with the cam 28; and a pin or stop 39 at the outer end of the finger normally rests against one side of the outer end of the body under the tension of thisspring, so that with the parts at rest they stand as seen in Fig. 3, or in full linesin Fig. 4.

' When this contact arm is applied to the arborA it is preferably set in parallelism with the hour hand H andas the latter makes its rotation t e Contact arm turns with it. As the contact arm turns, its body 21 moves with the arbor whereas the pin 37 engaging a tooth of the ratchet 22 prevents the finger 31 from turning with the arbor so long as this engagement continues. The

' movement of the body, however, moves its stub 26, and asthe cam 28 moves under said pin the latter is pressed farther and farther from the axis of the ratchet wheel until eventually it.disengages the tooth therein the spring 38 meanwhile. being put under slight tension. The result is that every fifteen minutes when the finger is released,

it moves forward until its stop 39 contacts with the body 21 In other words the construction is such that by the movement of the cam the pin 37 is lifted over one tooth of the ratchet 22 and permitted to engage the next.

When nowit is desired to set the device so as to'use it as. areminder clock (which in the present illustration is carried out by sounding the bell'at B) the operator takes one of the pins P and inserts it opposite the hour or the quarter hour indicating the-time at which he is to bereminded of something or to be awakened for instance. The tip 17 v -'of the pin fits into and projects through a hole 19 in the dial 11, whereas the insulated body -16 of the pin rests in the-hole 9 in the frame 6 so that the pin stands on a line parallel with the axis of the arbor and is held. at two points while it makes metallic contact only with the dial and its tip stands in the chamber between said dial and the front plate of the clock mechanism. Therevafter as the body member of the contact hand makes its rotation along with the hour hand,'the outerend of its finger (which is preferably provided with a flexible tongue 40) eventually comes into contact with the tip 17 of the pin. This closes-a circuit from the battery arbor A and the contact arm; to the "pin P, dial 11, wire 20, bell B, and-back to the battery. The alarm will therefore be sounded whether it be located within the clock or E through wire 10, clock C,

elsewhere, and it will continue to sound until L the contact arm slips off the pin which it must do in fifteen minutes at any rate, or

will do so sooner if the tongue 10 is sulficiently flexible. It is quite possible that the user may set another pin, say one hole farther forward, so as to remind him again fifteen minutes later, in case he cannot be aroused easily; and it is obviously possible that the device has a wide variety of uses which need not be explained herein. The inclination of the cam 28 at the bottom of the notch 27 serves two purposes. F irst it causes the automatic disengagement of the pin- 37 from the ratchet 22 at regular intervals whenthe alarm mechanism is not set, 1

and permits the finger 31 to jump with anintermittent movement-forward as first described above. Second, when the' alarm is set and the tongue 40 comes in contact with the pin P, as the finger 31'is swung away.

from the body 21 by such contact the cam 28 retracts or draws said finger inward (as the oval hole 34 in its ring 33 permits) and shortens the period through which the alarm will be sounded at B, rather than sounding the alarm for fully fifteen minutes.
