ALARM CLOCK.
Application filed August .11, 1921. Serial No. 491,340.
To all whom it may concern:
Be it known that I, EDWIN II. MILLER, a citizen of the United States, residing at the cityof Chicago, in the county of Cook and State of. Illinois, have invented certain newxand useful Improvements in Alarm Clocks, of which the following is a specification.
My invention relates to alarm clocks which provide visual means by which it can be known under all conditions, whether the mechanism is properly set to give the alarm. In addition to. the time-keeping ciated therewith, standard alarm clocks are usually provided with a control device by which the alarm when wound and set for the desired time, by a movement of the shutoff le er external to the casing, may be locked at the silent or unlocked by moving it to the alarm point.
But it may happen that through inadvertence the control device is not moved to unlock the striking mechanism in the alarm position; and that the user cannot recall after the light is extinguished, whether he has properly moved the shut-oil lever to the alarm point.
It is the object of my invention to provide a luminous signal which always will be visible in the dark when the alarm mechanism is in striking position, but which will be invisible when the alarm mechanism is not in proper position to give an alarm.
The principles of my invention are illustrated in the drawings in which Fig. 1 shows a front elevation of an alarm clock embodying my improvement. Fig. 2 is a perspective view of the same looked at from the left and from above. Fig. 3 is a similar view with the front portion of the casing removed. Fig. 4 is a similar view showing an alternative construction. Fig. 5 is a section on the line 55 of Fig. 3.
, Further describing my invention with reference to thedrawings in which like characters of reference denote like parts throughout, 1 is the usual drawn metal cup or foundation piece within which the mechanism of an ordinary alarm clock is mounted. 2 is the rear section of the outer casing which is secured to the foundation cup and which acts s a bell when struck by the hammer 3 which passes through the opening 4 to contact with said bell. The dial plate 5 is supported by the flange 6 of the framework and is normally secured in place by the front section 8 of the outer casing which also has a flange 9 to engage the edge of the protecting glass 10. A shut-off or looking slide 12 is placed inside the foundation cup in which it is secured by means of a lug having a head 14 and the body piece 15 which passes through the keyhole slot 16 and is upset to attach it to the slide. In order'that the slide may further be guiccd a second slot 16 is formed in the foundation cup 1, and a lever 17 is attached to the said slide by means similar to that last described. Said lever is extended upwardly, however, and includes a screw 18 which passes through the slot 19 in the outer casing. Said slide is adapted to engage the hammer '3 and prevent it from sounding when the lever 18 is moved to the right, and to free it when moved to the left, as indicated in Fig. 2.
The outer casing 8 ofthe clock has an annu- Patented Jan. 3, 1922.
lar flange 20 in which is placed a sight opening 21, and back of said opening on the dial is provided a luminous spot or glower 22. Said spot is formed by the application, at the proper position with reference to said sight opening, of any self-luminous ma terial such as zinc sulfide combined with suitable salts of radium, thus forming a. glow spot or glower which, unobstructed. will show in the dark through the said window or opening.
Referring to Fig. 3; the shield piece 23 is mounted upon the shut-off lever 17 and held in place by the screw head 18 or by any suitable means. The shield piece has an overhung portion 2st in such position with reference to the alarm lever and the glow spot that when the alarm is locked by the slide 12 in the silent position, the overhung portion 24 will close the sight opening 21 and conceal the glower, but when the shut-off lever is moved to the alarm position the said overhung portion will be moved with it so that the sight opening will be unobstructed and the glower 22 disclosed.
A slight modification of my device is shown in Fig. 4: in which the movable shield piece 23, attached to the shutoff lever 17 is provided with an overhung portion 28 upon which the self-luminous compound 28 1s placed Th1s overhung portlon 1s 1n such posit on with reference to the shut-off lever and the sight opening that, when the alarm is locked in. the silent pos1t1on, the glow spot Wlll be with n the casing and invisible; but when the shutofi lever is moved to the"alarm position the glow spot will register with the si ht opening and be visible therethrough.
'In either case, however, the result is the same, that a complete illuminated visual indication is given whenever the alarm str1ker is adapted for operation; but. that, when no positive signal is given, the same is in inoperative position.
. I have illustrated my invent1on by reference to a practical and operative application thereof in connection with an alarm clock of'standard construction. But I am not limited to any particular form of alarm clock construction as my invention'may be" used Whenever means is prov1ded for lock-' I mg or free ng. the alarm mechamsm by acorrespondingly alternatively movable device, to indicate a predetermined position thereof.
' I claim L 1. In an alarm clock; a casing having a sight opening, a glower operatively disposed relatively to said opening, a'movable device for'controlling' the alarm striking mechanism, and means associated with said movable device for causing said glower to be exhibited at said sight opening to indi- 1 ,aoasae cate' a predetermined condition of the said striking mechanism..
2. In an alarm clock; a casing having a sight opening, a glower adapted to be exhibited at said opening, a movable device including a shut-off lever for controlling the alarm striking mechanism, and a shield piece having a depending member and movable by said shut-off lever relatively to said 4. In an alarm olock;a casing having a sight opening, a glower fixed in the rear of and adapted to be exhibited at said opening, a shut-oil lever for controlling the alarm strikin mechanism, a shield piece on the shut-ofi lever, and a depending memher-0n said shield piece movable relatively to said opening whereby saidopening may alternatively be opened or closed by corresponding movements of the shut-off lever.
In Witness whereof I have. hereunto set my hand at Chicago, Illinois, this 9th day of August, 1921.
