Application filed February 8, 1897. Serial No. 622,458. (No model.)

To all whom, i2; 777/601/ concern: (1 d connected at 61 The spring 1 extend- Be it known that I, BENJAMIN ELLIOTT 7A ing by the joint in the lever, revents the arm TERs, of Brockton, in the county of Plymouth d from swinging on its pivot 61 until the and State of Massachusetts, have invented a counting operation has been completed, and new and useful Counting and Signaling Apthe arm d brings up against the stop d when paratus, of which the following is aspecificathe arm 61 is swung on pivot 61 against the tion, reference being had to the accompanyforce of spring CV, for a purpose explained ing drawings, in which below.

Figure 1 is an elevation of my apparatus The signaling apparatus consists of the in- :o with the case removed. Fig. 2 is a sectional sulated electrode A, which forms one termi- 6o elevation on line 2 2 of Fig. 1, looking in the nal of the battery-circuit, and the spring-elecdirection indicated by the arrow. Fig. 3 is a trode B, which forms the other terminal of partial elevation, and Fig. l is an elevation the battery-circuit and is normallyin contact showing my apparatus with the casing in with electrode A.

The disk a is turned once for each revolution My invention is especially adapted for use of disk a by pin 0 on ratchet c engaging with with a telephone in places where the charge gear 9 and disk a is turned once for each for the telephone is regulated by the number 40 revolution of disk a by pin (1 and on gear of times it is used. In such a case the user 0 G engaging with gear 0 thus causing disk of the telephone calls up the central office a to register the units, disk a the tens, and and asks to be connected. If the line is not disk c the hundreds. The disk a has an busy, the operator at the central office before arm m projecting from its under side. This connecting the user tells him to count, where 5 arm is so arranged with relation to a stop on upon the user presses the lever from right to 5 in the casing that when the counter registers left, counting one and also giving a signal to 999 the arm m is against stop an and prethe operator that he has done so. vents the further operation of the counting I have shown the end of the spring-elecmechanism. The counting mechanism is optrode B provided with a shoulder which en- 50 erated by the jointed lever, made up of arms gages with the toothed end of finger f. It

Will be clear that by this construction the circuit is broken and closed by the passage of finger f by the end of electrode 13 and that this opening and closing Will give the signal to the operator at the central office.
