Device for Waking Persons from Sleep
Patent No. 256,265
Issued: April 11, 1882
. . . The object of my invention is to construct a simple and effective device for waking persons from sleep at any time which may have previously been determined upon, the device being also adapted for use in connection with an electric or other burglar-alarm apparatus, in place of the usual gong-alarms. . . .
Ordinary bell or rattle alarms are not at all times effective for their intended purpose, as a person in time becomes so accustomed to the noise that sleep is not disturbed when the alarm is sounded. The main aim of my invention is to provide a device which will not be liable to this objection.
In carrying out my invention I suspend a light frame in such a position that it will hang directly over the head of the sleeper, the suspending-cord being combined with automatic releasing devices, whereby the frame is at the proper time permitted to fall into the sleeper's face . . . the only necessity to be observed in constructing the frame being that when it falls it will strike a light blow, sufficient to awaken the sleeper, but not heavy enough to cause pain. . . .
