MESSAGE AND TIME RECORDER.

SPECIFICATION forming part of Letters Patent No. 402,120, dated April 28, 1889.

Application filed August 20, 1888. Serial No. 283,244. (No model.)

To all whom it may concern.-

Be it known that I, JOHN C. \VILSON, of Boston, county of Suflfolk, State of Massachusetts, have invented an Improvement in Message and Time Recorders, of which the following description, in connection with the accompanying drawing, is a specification, like letters on the drawing representing like parts.

In another application, Serial No. 225,-l3i, filed by me January 25,1887, a message and time recorder is shown wherein messages are recorded and the time of the reception of a message is printed upon the same paper upon which the message is received. An electro magnet is employed to operate the timestamp, and a circuit-changing device is employed to control the circuit of the said electro-magnet The circuit-changing device is arranged to be operated at each time a message is received. In this my present inven tion a .rccordinginstrument is employed of any well'known construction, and a timestamp operated by an electro-magnet is also employed, the circuit of the said electro-magnet being operated by a circuitchanging device. A motor mechanism is employed. which causes the said circuit-changing device to operate the circuit of the electro-magnet of the time-stamp at definite intervals in contradistinction to being operated only at the time of the reception of the message. The timestamp employed is similar to that shown and described in United States Patent No. 205,808, dated October 22, 1882, granted to J. C. lIinchman, it comprising adial and pointer or hand, movable one with relation to the other, and a presser. Tlhemotor mechanism employed for operating the said circuit-changing device may be an ordinary clock-motor, designed to move the circuit-changing device continuously, so that at definite intervals of time it may operate to change the condition of the circuit of the electro-magnet of the timestamp.

The drawing shows a portion of a signalreceiving instrument and time-stain p, an d. circuit-changing device for the circuit of the electro-magnet of the time-stamp and a portion of an ordinary clock-motor i'or continuously moving the said circuit-changing device.

The signal-receiving instrument A is substantially such as shown in application, Serial No. 278,170,1iled by me June 25, 1888, and the dotted line leading from it represents a strip of paper upon which the signal is printed.

I I desire it to be understood that so far as my present invention essentially consists any other form of signal-receiving instrument may be employed.

The time-stamp comprises the dial c, the pointer or hand c,the toothed wheel 0 which is engaged and rotated continuously by any suitable motor mechanism, the arbor of the said pinion turning in a base-plate, a presser, b, and armature b attached. to it, and an electro-magnet, b. This time-stamp is substan tially as shown in the application referred to, and its principal of operation as regards a time-printing mechanism is substantially the same as in the patent referred to. The

'electro-magnet 7) is included in a circuit, 1)",

including the battery if, the break-wheel Z), and the contact-pin D The break-wheel Z) is herein shown as fixed to a shaft carryinga toothed wheel, U, which is engaged and rotated by a pinion, U. It is designed that the pinion b shall be mounted upon the secondhand arbor of a clock, and therefore rotates once each minute, and the wheel Z) is of suflicient size to make one complete revolution each live minutes. 7 It will therefore be seen that as the pinion U is driven by any suitable continuously moving clock mechanism the breakavheel I) will co-operate with the pin 1)" and thereby elteet a change in the condition of the circuit I) and actuate the time-stamp. The break-wheel l) and pin b as herein shown, constitute the circuit-changing device; but it is obvious that any other suitable wellknown form of changing device may be substituted for it without materially departing from the scope oi this invention.

\Vhile I have herein shown a time-stamp comprising a dial and pointer movable one with relation to the other, I desire it to be understood that I may employ any other wellknown form of time-stamp.

I claim 1. The signal-receiving instrument and a time-stamp comprising a dial and pointer, one of which is continuously movable with relation to the other, a presser, and an electro-magnet for moving the presser, combined.

cuit of the said electro-magnet, and a motor mechanism for said circuit-changing device,

all substantially as and for the purpose set [5 forth.

In testimony whereof I have signed my name to this specification in the presence of two sub scribing Witnesses.

JOHN 0. WILSON.

BERNICE J. NoYEs, FREDERICK L. EMERY.
