Description

Sept. 19, 1933. D. c. WISELY I ALARM WRIST WATCH Filed June 2, 1932 Patented Sept. 19, 1933 NITE STATES PATENT OFFICE This invention relates to alarm wrist watches. The principal object of the invention is to so construct a watch of the character specified that it will be inaudible and the vibratory alarm mem- 5. her, with which all such watches have heretofore been equipped, will be eliminated, the alarm member of the present watch acting to induce steady pressure upon the flesh of the wrist of the wearer. A further object of the invention is to so con struct such a watch that the induced pressure will be maintained, at constant strength, until manually released.

Another object of the invention is to so com 1 struct such a watch that the visual alarm time set race with which all such watches have heretofore been equipped will be eliminated, the time indicatingmeans being utilized to set the alarm.

A still further object, of the invention is to so construct such a watch that'the custo actuating means for the alarm member, which must be reenergized or wound up tor each op eration of the alarm, such as that with which go watches of this type have heretofore heeh eouimned, will be eliminated, the actuat= of the present watch being oi. constant and pet potential and req no wind? iug or other energizing process.

Another object is to install certain oi the ca Q eor of the watch casing, thereby reducing the size of the casing heretofore reo all prior 112-: 1: watches and for the purpose oi least disturbing the adopted arrangements and association of parts of the usual watch movement.

A further object is to provide an arrangement in which no opening through the walls oi the watch case is required for the movement oi the striker, thereby minimizing the hazard of dust or other foreign matter entering the moch anism or movement of the watch.

Yet another object of the invention is to so construct such a watch that the alarm mechanism will consist of but few parts, and those oi small size and light weight, whereby the watch will be but little larger and oi barely greater weight than a similar watch without the alarm features,

With these and other objects in view, such as will hereinafter more fully appear, the invention consists, generally. in the combination or ele= merits and arrangement of parts, such as shown in the accompanying drawing, described in the following specification, and particularly pointed out in the appended claims. v

outer extremity,

In the drawing:

Figure 3 is a rear face view of the watch:

Figure 4 is a side elevation looking in the direction of the arrow N of Figure l, and show= ing the alarm member in inoperative or nousol position;

Figure d is o s View, but showing the alarm member he operative or alarm position;

Figure 6 is a sectional view on the line VI- VI of the l.

In the drawing, there is shown a wrist watch comprising a casing" to within which is mounted the usual watch movement 21. The casing 2c is provided, at its ends, with the customary strap or hand receiving transverse pins 22.

Prolectiug forwardly from the watch movement 21 is the usual hour hand spindle 23 with hour hand 2d thereon and projecting laterally from the movement 21 through the casing 2o is the usual wind and set stem 2-5 with crown 2o utits Secured to the hour hand spindle 23 inwardly of the hand Ed is a toothed disk 27 adapted to have rotative movement imparted to it from the stem 25 when the latter is in its setting position. The mechanism for imparting this rotative movemerit to the dish. 27 is of the customary standard construction, and, as it forms no part of this inveution, no attempt at illustration has been made,

Mounted on the spindle 23, but free to rotate 5 thereohout and outwardly beyond but resting against the race of the 27, is another disk 28. This second disk 23 is maintained in frictional contact with the face of the disk 27 by means of a coiled spring" 29 siurouhdiug the spindle 23 and mo interposed hetweeu the face oi the disk 28 and the hub of the hour hand lid, as shown in Figure 6. The tension off this spring 25) is such that the disk 28 is normally caused to rotate with the dish 27 and spindle 23, but may he held against such rota- I tioh ha a manner and for a purpose to be hereinai'ter described.

Pivotally mounted, tit 30, upon the face of the movement 21 is a lever, one arm 31 of which extends across the face of the movement in the in) plane of tho'disk 284 and has its end adapted to a substantial right angle to the i the casing 20, as, also, shot ride upon the periphery of said disk or to be forced, by the action of a spring 32 into a ratchet notch 33 in the periphery of the disk. The other arm 34 of the lever has its end adapted to pass through an aperture 35 in the web oi the side wall of the watch casing 2o,

Adapted to the rear face or the casing 2e and secured thereto by means or" screws 36, as shown in Figure 3, or by spot welding, or in any other desired manner, is an alarm member, preferably made of spring steel, and comprising a transverse bar 37 normally lying flush against the rear face of the casing and a longitudinaliy extending arm 38 normally lying flush against that side wall of the casing opposite that from which projects the wind and set stem The flat 0 bar 2'? is b of the anti 38 and they are integral with each othc Elie end of the arm opposite the end which joins the bar 37 is provided an. offset pointed lug Pivotally mounted, iii,

he face of n Figure 3, is a lever, one arm Q1 of which extends across the rear face of the casing from the pivot point do adjacent one side of the casing to the opposite side, terminating a short distance outwardly beyond the side oi the casing. The other arm 42 of this lever is at a substantial right angle to the arm a1 and extends normally a short distance outwardly beyond the opposite side of the casing and has its end in a position to be normally contacted by the pointed lug 39 on the 38 of the alarm member.

When'the alarm inember is in inoperative or non-alarm position, it occupies the position shown in Figures 3 and i, and the of the lug 3 bears against the inner face of the lever arm and the alarm arm 38 is in the-path of the end oi the lever arm as.

The tension oi spring steel alarm member is such that its bar 37 is under a constant urge to twist about its longitudinal axis with a resultant tendency to raise the upper edge of said bar from its normally maintained position flush against the rear face of the watch casing 28. This constant tendency is to raise the bar 37 from its position shown in Figure 4 to that shown in Figure 5, with resultant corresponding sidewise motion of the arm 38 as therein shown. This constant twisting tendency is, however, normally opposed and twist prevented by the contact of the point of the lug 39 against the inner face of the lever arm 42.

In operation, let it be assumed, for example, that it is ten'oclock, P. M., as shown by the arrangement of parts in Figure l, and it is desired to set the alarm for seven oclock, A. M. The hands of the watch are turned backward through the medium of the setting crown 26. As the disk 27 is rotated in this counter-clockwise direction, the disk 28 is frictionally rotated therewith until its peripheral ratchet notch 33 is brought into alignment with the end of the lever arm 31, whereupon the end of this arm, under the urge of the spring 32, engages the notch and prevents further counter-clockwise rotatlon of the disk 28. The hands of the watch are further turned backward until the hour hand 24 points to the numeral 7 on. the dial of the watch, at which time the parts will be in the positions shown in Figure 2. In order to insure engagement of the inner end of the lever arm 31 with the notch 33, it is preferred that the hour hand be given one full counter-clockwise rotation from 10 to 10 on the dial and further rotation to 7. This will insure proper engagement irrespective of the original relation between the hour hand 24 and the notch The hands of the watch are then reset, in cloclrwise manner, to their original position with the time of ten ocloclc indicated, whereupon the parts the will be in the positions shown in Figure 1', disk 28 having travelled, clockwise, with th 27 so that the notch 33 has moved away free end of the arm 31 which now rides upon the edge of the dislr.

Time passes until seven ocloo A. M., when the normal action of the watch will have R brought the parts to the positions slio i Figure 2. As the end of the lev s forced into the notch 33, the end 0; 1a.. arm 3% of the lever is PIOjSC'u dilly through the aperture 35 in the cats push ing the arm 38 of the alarm member outward- 1y from its position flush against the side of the casing 20 until the point of the of 5. is cleared from its contact with of the lever arm 1.2. The spring in the bar 3? is then free to act and tl 37 is twisted to the position shown in 5, causing the pointed lug 39 to forcefully see into the flesh of the wrist of the watch weer The wearer of the watch, if asleep, will oe quickly awakened by the pressur of this pointed lug 39 upon his wrist and, to free himself from this pressure, he will manually press the 38 back to its retracted position alongsic the edge of the casing 20 and manually swii the lever arm 41 to the position shown by ted lines in Figure 3, the arm 42 thus being swung outwardly a greater distance, as also sliown by dotted lines, so that it will overlie the point of the lug 39 in its laterally outthrust position.

As further time passes, the notch the dish 28 is carried past the end of the lever arm 31, the latter again riding upon the edge of the disk, and the end of the lever arm 3% is swung back to its normal position and the alarm arm 38, owing to its inherent spring, returns to its normal position flush against the side of the watch casing, as shown in Figures 1., 3 and a,

The lever arm 42 is, however, preferably to be left in the position shown by dotted lines until it is again desired to set the alarm. Otherwise, at seven oclock, P. M., then following, the alarm member will again be tripped and automatically operate. When the alarm is reset, however, the lever arm 41 must be moved back to the position shown by full lines, so that the arm. 42 will be correspondingly retracted and permit the alarm to operate at the time for which it has been set.

If it should be desired to cover the movable parts 37 and 41 so that they will not be in contact with the flesh of the wearer of the watch, this can be readily accomplished by means of a suitable cover plate secured to the rear face of the watch casing 20, in any desired manner. Such ail-expedient, being obvious to any one skilled in the art, calls for no special illustration, so none has been made.

Thus, it will be seen that there has been provided an alarm wrist watch wherein there is no vibratory. alarm member, no visual alarm timeset mechanism, no alarm mechanism to be wound up after each operation, and where the alarm parts are few in number, small in size, and light in weight. Yt, wlthall, an alarm watch which cient for the purpose intended.

It is, of course, obvious to those skilled in the art that many changes and modifications in the size, shape, and arrangement of parts may be made over those illustrated in the awing and specifically described without depart from the principles of this invention.
