ALARM-CLOCK.
Specification of Letters Patent.
Patented Feb. 1, 1921.
Application filed August 22, 1919. Serial No. 319,222.
' dent of Chicago, in the county of Cook and State of Illinois, have invented certain new anduseful Improvements in Alarm-Clocks, of which the following is a specification.
My invention is an improvement in alarm.
clocks, and has for its object to provide mechanism for use in connection with alarm clocks for converting said clocks into noiseless alarms, whose sound will carry only to the one person whom it is desired to waken.
In the drawings:
Figure 1 is a perspective view showing the clock in use.
Fig. 2 is a front view ofthe clock with parts broken away.
The present embodiment of the invention is shown in connection with a clock 1 of ordinary construction, the said clock having a hammer 2 controlled by the clock movement for oscillating the same at predetermined times. The usual bell is replaced by a diaphragm 3 ofany suitable material, which is arranged within an extension 4.- from the clock case. This extension has a nipple'5 at the opposite side of the diaphragm from the hammer, and a tube 6 of rubber or the like has one end connected with the nipple. The other end of the tube is connected with the body of a tubular fork 7, each arm of the fork having an. ear piece or tube 8. In use, the clock is arranged at the bed side, upon a suitable stand 9, and the tube 6 leading from the extension is passed over the head board of the bed 10 to the person whom it is desired to waken. I
The ear pieces are engaged within .such persons ears as shown, and it will be obvious that when the alarm goes off, which will at the time appointed, the sound vibrations will be carried by the flexible tube directly to the users ears, and the clock will be practically noiseless to any other but the user.
I claim:
1. In combination with a clock having an alarm hammer and a diaphragm with which the hammer cooperates and an extension chamber in connection with the clock case, said diaphragm being arranged transversely of the chamber, and the hammer being within the chamber, said extension having a nipple on the opposite side of the diaphragm from the hammer, a nd conducting mechanism for the sound vibration connected with the nipple, said conducting mechanism comprising a flexible tube branched at the end remote from the clock and having ear pieces for the purpose specified.
2. In combination with a clock havin an alarm hammer and a diaphragm with w ich the hammer cooperates and an extension chamber in connection with the clock case, said diaphragm being arranged transversely of the chamber, and the hammer being within the chamber, said extension having a nipple on the opposite side of the diaphragm from the hammer, and conducting mechanism for the 'sound vibration connected with the ninnle.
3. In combination, a clock having an alarm and an extension chamber in which the alarm isarranged, an ear piece, and a flexible connection leading from the chamber to the ear piece.
4. In combination, a clock having an extension chamber provided with a diaphragm and an alarm whose hammer is in the chamber andcoiiperates with the diaphragm, an ear-piece, and a flexible; hollow connection leading from .the chamber to the eariece.
