' (o1. s 1s) 6 Claims.
My invention relates to a new and useful improvement in an alarm device adapted for being worn on the arm, wrist or other part of a persons body and intended as a mean for awakening the person at a predetermined time.
It is an object of the present invention to provide a device of this class which will be simple in structure, economical of manufacture, durable, compact, light, easily and quickly attached to a persons body and of high efficiency.
Another object of the invention is the provision of the device of this class so arranged and constructed that a. tapping member may be caused to oscillate and strik the person's body at a predetermined time in order to awaken the person.
Other objects will appear hereinafter. The invention consists in the construction and arrangement of parts hereinafter described and claimed.
Theinvention will be best understood by a reference to the accompanying drawings which form a part of this specification and in which:
Fig. l is a top plan view of the invention showing it applied to a persons arm.
Fig. 2 is a top plan view of the invention slightly enlarged with parts broken away.
Fig. 3 is a sectional view taken on line 3-3 of Fig. 1, slightly enlarged.
Fig. 4 is a sectional view taken on line 44 of Fig. 3.
Fig. 5 is a fragmentary View taken on line 5-5 of Fig. 3.
Fig. 6 is 'a sectional view taken on line 6-6 of Fig. 5.
Fig. 7 is a detail View of a portion of the device appearing in Fig. 4.
Fig. 8 is a fragmentary sectional view taken on line 88 of Fig. 7.
Fig. 9 is a fragmentary side elevational view of a release mechanism used in the invention.
Fig. 10 is a view similiar to Fig. 9 showing the release mechanism in another position.
Fig. 11 is a fragmentary sectional view taken on line of Fig. 2 and. slightly reduced.
As shown in the drawings, the invention comprises a housing ll having a cover IS, in which is mounted a transparent lens I9, positioned over a dial 26, forming a part of the clock mechanism 2 I, which in general is of a common construction used for driving the hands 22 and 23.
The shaft 24 serves to drive the minute hand and the sleeve 25 serves to drive the hour hand. Press fitted over this sleeve 25 and rotating in unison therewith is a sleeve 40, carrying at its base the gear 39 provided with the teeth 42. Em-
and gears M, 58 and 59 to drive the elementsv 6|, .62. Winding force is transmitted from the knob 65, through gearing 59, 53, 51 and shaft 50 to the spring 56. During the winding operation the ratchet 52 rides idly under the pawl 53. When the escapement 5?, 55 is released, the gear 49 is rotated by the spring 56, through the shaft 50, sleeve 5|, ratchet 52, and pawl 53 which is attached to the gear 39. The arm 6| is simultaneously rotated by the spring 55, and the spring tapper 52 is actuated by the rotation of the arm 6|.
The spring drive hereinabove described is old in the art and forms no part of the invention in itself, apart from the combination in which it operates. it will raise it into the elevated dotted-line position shown in Figure 11. When the arm 6| disengages therewith, this tapper 52 will spring downwardly into the lower dotted-line position shown in Figure 11 so as to strike the arm of the wearer, there being a suitable slot formed in the bottom of the case. The construction is such,
of the wearer and the clock mechanism Wound As the arm 8| rides under thi tapper by means of the stem, the hub 26 may be rotated through gear 29 and stem 30' to any desired position, the pointer 64 indicating its position. This hub carries a notch 38 and projecting upwardly from the gear 39 is a spring arm 4|. When the notch 38 registers with the spring 4| the gear or hub 26 will move downwardly into the position shown in Fig. 6 and the arm 35 will move down from the dotted line position shown in Fig. 6 to the full line position, thus disengaging the detent 31. If th stop 66A has been pulled outwardly to disengage the escapement wheel 43, this escapement wheel 43 may be permitted to rotate, thus permitting a rotation of the shaft or stem 60 through the gearing described to bring about the tapping of the arm by the tapper 62.
In use, after the device is strapped upon the wrist the hub 26 may be rotated to any desired position relatively to the shaft 24 and the sleeve 25 which drive the minute and hour hands. This hub 26 will, of course, be riding on the spring 4| as shown in Fig. and the arm 35 will be flexed upwardly against its resiliency into the dotted line position shown in Fig. 6 so as to engage the arm 38, and lock the detent against rocking movement. As the clock mechanism continues to operate the gear 42 will rotate so as to bring th espring t! into registration with the notch 38 in which event the parts will move to the full line position shown in Fig. 6 so that the arm 35 will clear the detent arm 36 and permit operation. The spring 56, which of course, will have been previously wound, will effect a rotation of the gear 51 and thus through the gear 58 and the gear 59 bring about a rotation of the shaft 60. As the shaft 60 rotates the spring arm 62 will be alternately raised and released for springing downwardly through the slot formed in the base of the housing so that the tapper 62 will be permitted to strike the Wrist of the wearer.
In this way, there is provided an alarm mechanism which may be set to any desired time and which, when set off, will serve to awaken a person wearing the device without producing any noise and without producing the shock which sometimes is eiiected by waking a person with a loud noise.
. It is. recogn zed that various changes and modifications may be made in the detail of tructure without departing from the general nature of the invention and it is the intention to embrace such modifications within the claimsset out herein.
