Specification'forming part of Letters Patent No. 182,091, dated SeptemberIQ, 1876 application filed February15, 1 876. 1 f f To all whom it may concern: I

Be it known that I, CHARLES J .WILEY, of the city and State of New York, have invented an Improvement in Printing-Telegraphs, of which the following is a specification:

This improvement relates to that class of printing-telegraphs in which the type-wheel is revolved by a train of gearing and spring or weight, and the type-wheel is allowed to move by an escapement under the control of an electro magnet or magnets.

My present invention consists in a mechan- 'ism that is automatic, and disconnects the revolving mechanism simultaneously with the stopping of the type-wheel at unison. The reverse movement connects the revolving mechanism with the type-wheel, and liberates the same from the unison-mechanism stop.

I make use of a ratchet-wheel upon the shaft that drives the type-wheel but the type-wheel itself is upon a loose sleeve upon said shaft, and there is upon this sleeve a compound detent, that connects with the ratchet-wheel in one direction and with the unison-stop in the other direction, so that when one is locked the other is unlocked. The unison-stop is a ring with a notch that prevents the compound detent moving except at one point, and there is a screw that receives an end motion as the type-wheel revolves, and after one or more complete turns of the type-wheel the unison can come into action when the detent arrives at its notch; but if the printing-lever is operated at any time it restores the screw and other parts to their original position, disconnecting the detent from unison, and connecting the type-wheel and motor.

In the drawing, Figure 1 is a plan of the type-Wheel aiid its actuating and unison mechanism. Fig. 2 is an elevation of the compound detent, and Fig. 3 is an elevation of the uni- 1 son-ring.

The frame a, driving-wheel b, pinion b, escapement-wheel c, and its shaft 0 areof usual character, and the escapement-pallets that op crate to control the revolution of the wheel a are of any desired character, the same being moved by electro-magnets, as now usual. The

' ratchet-wheel d is fastened upon the shaft 0;.

but the sleeve 6 is loose thereon, and to this Sleeve 6 the type-wheel f is fastened and the arm It is also fastened. Upon this arm It is the pivotui-ofthe compound detent 0 1', the end r being in the form of a tooth to enter between the teeth of the wheel d, and the end 0 of the detent being a finger,adapted to enter the notch 2 in the unison-ring 70. These detents o and r are at opposite sides of the sleeve 6, and operate in opposite directions. Hence if one, 1, is in contact with d the other, 0, is out of the notch 2, and vice versa. A spring, l, tends to move the compound detent in one direction, and a lever, m, acting with the impression -lever or printing magnet it, serves to move the detent in the other direction. The drawings represent the parts as arranged so that the spring tends to press the detent 0 into the notch 2, and the lever m to lift the same out. The screw 8 is adapted to slide endwise upon the sleeve e, and while the heel 3 of the detent o rests upon that screw such detent 0 cannot fall into the notch 2 but as soon as the screw is moved endwise Sllffik.

type-wheel would be stopped by a pin upon the lever falling into a notch in the bottom of the screw-thread, and the compound detent would be connected with the ratchet-wheel or disconnected therefrom by the action of the ring.

The screw sis represented as upon afeather on the sleeve 0, and pressed toward the arm h by a spring, t, and there is a segment of a nut upon the lever m at the block 4. Hence, as the screw revolves with the type-wheel, the nut-segment will draw the screw endwise away from the heel of the detent 0, and allow that detent o to rest upon the unison-ring, and drop into the notch 2 when it arrives there. As

r locks the type-wheel to the motor, and the screw is forced along to ward the arm h by the spring; but if the screw did not revolve, but were capable of end motion, as aforesaid, a tooth upon the heel of the detent might be used to give the end motion to the screw. There may be one or more type-wheels upon the sleeve 0, according to the character of the instrument. a

I claim as my invention- I 1. The combination, with a type-wheel and its motor, of a compound detent that simultaneously disconnects the motor and locks the type-wheel, or the reverse.

2. A notched unison-ring and detent, 0., in combination with a type-wheel and a screw, substantially as set forth.

A screw receiving an end. movement as the type-wheel revolves, in combination with such'type-wheel, and unison mechanism brought into action by the end movement of the screw, substantially as set forth.

4:. The combination of the ratchet-wheel d, compound detent 0 r, sleeve 0, type wheel f, unison-ring k, screw 8, and lever m, substantially as and for the-purposes set forth.

5. The combination, with the notched unison-ring and the liberating mechanism operated by the press-magnet, of the compound detent o r, and a spring to press the detent 0 into thenotch of the unison-ring, substantially as set forth. v

Signed by me this 14th day of February,

CHARLES J. WILEY. Witnesses:
