First Claim
Patent Images
1. An alarm device capable of providing both a time alarm and a fire alarm comprising:
- (a) a timepiece providing an output representing time of day;
(b) means for setting an alarm time and providing an output representative thereof;
(c) means to compare said time of day output with said alarm time output and to provide an output when the two coincide;
(d) an electrically operated alarm;
(e) a switch coupling the output of said means to compare to said alarm;
(f) an electronic smoke detector;
(g) means to amplify the output of said smoke detector; and
(h) means coupling the output of said means to amplify to said alarm.

Abstract
An alarm device functioning both as a time alarm and a smoke and fire alarm, which includes an electric clock with an alarm-setting device, an electrically-activated alarm, cooperating contacts on the clock and alarm, a switch coupling the contacts to the alarm to permit switching the time alarm on and off, an electronic smoke detector and an amplifier to amplify the output of the smoke detector as a second input to the alarm.

3. A battery operated alarm device capable of giving a time of day and a fire alarm comprising:
-
(a) a battery; (b) an electric clock including a clock motor and gearing with clock hands attached thereto receiving input power from said battery; (c) means, including an alarm hand for setting an alarm time; (d) contacts coupled to said clock hands and said alarm hand respectively and adapted to close when said hands are in alignment; (e) an alarm; (f) a switch coupling said contacts to said alarm, said battery coupled across said alarm through said contacts and said switch; (g) means for detecting the presence of smoke and providing an output indicative thereof; (h) means to amplify the output of said means for detecting and provide an amplified output; (i) latching means for latching in response to an output from said means for amplifying; and (j) means for coupling the output of said latching means to said alarm. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10)
