Abstract: 562,351. Time alarm signals. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 17, 1943, No. 2632. Convention date, April 24, 1942. [Class 118 (ii)] [Also in Group XIV] The top 10 of a speaker's lectern is adjusted up or down by push buttons 25, 26 operating an electric motor 33 and racks and gears 31 whereby a hollow box support 12 telescopes in a base 11. The top also contains a timing clock 20 to operate a warning light 21, tubular lamps 17, microphones 23, an ordinary electric clock 19, and is constructed with side recesses 16 for papers, a cork plate 15 and an inclined front panel 14, a lamp switch 18, and a gavel block 27. The various panels and plates of the top may be mounted on cork, &c., and when possible the panels themselves are of cork, &c. In operation the push button 25 closes armature circuit 33a and field circuit 33f of motor 33 to raise the top while push button 25 reverses the connections to reverse the motor and lower the top. An interlock toggle 43, Fig. 7 (not shown), prevents both push buttons from being operated simultaneously. An automatic stop on the support 12 limits the rise and fall of the table to prevent overrunning by breaking contacts 45 or 46, Fig. 6 (not shown), coupled to the motor circuits but leaving the motor available for starting in the opposite direction by the appropriate push button. Manual setting of the hand 28 of the timer clock 20 sets the position of cams 53 and 54 fixed on shaft 48. Cam 53 thereby closes contacts 55 to rotate the motor 51 clockwise. Cam 54 momentarily closes the contacts 56 and opens them again when the hand 28 passes over the first minute division of the clock dial. On manual turning of the hand 28 the shaft 48 slips on the shaft 49 at the friction collar 50 since the shaft 49 is held by the usual gearing of the clock motor 51. A stop 57 on the clock dial prevents the hand 28 from being turned in the wrong direction. The clock motor rotates until the last minute division on the dial is reached when cam 54 closes contact 56 to operate the warning light showing the speaker that his speaking time is about to expire.
