Alarm Clock For The Deaf

Be it known that I, HIRAM PHELPs ARMS, a citizen of the United States, residing at lest Hartford, in the county of Hartford and State of Connecticut, have invented a new and useful Alarm-Clock, of which the following is a specification.

The invention relates to an alarm clock which is designed to awaken persons who are wholly or partially deaf.

The obj ect of the invention is to provide a simple and cheap alarm clock which may be placed beneath the pillow of a bed occupied by a person that is hard of hearing and which will effectively awaken such person without disturbing others in the apartment. This object is attained by constructing a clock which can be set to let off the alarm at the desired hour, with a percussion board and a hammer which, when the alarm is freed, will produce a concussive eli`ect sufficient to awaken the deaf sleeper, and with a shield which so covers the clock and the hammer as to deaden the sound waves and protect the mechanism from interference and disarrangement by the pillow and clothing of the bed or its occupant.
