QPEGIFICATION forming part of Letters "Patent No. 340,867, dated April 27,1886.

Application filed February 1'3, 1356. Serial Xe. 101,618. (Yo model) To all whom it may concern.-

Be it known that 1, JAMES l Enntion, a citizen of the United States, residing at Baltimore, in the State of Illaryland, have in vented certain new and useful Improvements in "Winding-Indicators, of which the following is a specification.

Myinvention relates to a wind-up indicator for clocks.

The object of the invention is to provide an indicator having improved actuating mechanism that will expose the sign instantaneously, indistinction to exposi ng it by a gradual n1ovcment; and a l'nrther object is to provide an audible signal that will be sounded immediately upon the sign being exposed.

The invention is illustrated in the accompanying drawings, in which Figure 1 is a view of the indicator, signal-gong, and actuating mechanism, including the mainspring of the clock-movement, Fig. 2 is a view of the clockdial and sign or indicator. 3 is a vertical section oi the clock-case, showing the indicator-actuating mechanism and a sullicient portion of the clock-mwemcnt to render the operation intelligible.

The letter A designates the driving-spring of an ordinary cloclomovement, and A the arbor on which the driving-spring is wound.

B designates a portion of the clock-frame; C, the dial; i), the indev-arbor, which carries the hands ii and 1 As any further illustration of the parts of an ordinary clock-movement might be eonfus ing, the same are omitted.

The dial 0 has a hole, (1, below the figure 12, and the wind-up sign or indicator G is carried on the front arm of a pivoted yokc,1*l, and said sign is exposed in front of the hole a. (See Fig. 2. This sign may have printed on it any suitable notice, such as \Yind me up, or Time to wind. The front arm of the yoke H is pivoted loosely on the index-arbor D, and said arm extends up in front of the clock-frame l3, and the back arm has a pivot, 11, at the back of the clock-frame, and the two arms are connected above the clock-frame by a cross-bar, H. The two arms and the crossbar comprise the yoke. It will thus be seen the pivoted yoke H, which projects upward, is free to tilt from one side to the other, and is limited at each side by a lived stoppin, c.

The back arm of the pivoted yoke carries a weight, (2, which serves to throw the yoke the moment it is tilted or moved beyond its center or beyond a central vertical line. The weight also serves as a striker or hammer for the gong I to produce the audible signal.

The yoke is tilted from one side to the other by a shifter device, L. This device consists of an open frame or slotted head, L, which is mounted in a stem or shank, e, and has movement in a horizontal plane. The stem or shank. 6 moves in a guide, f, which. keeps it in proper position. The back arm of the pivoted yoke extends up through the open frame or slotted head L. The greatest dimension of the slot in the frame or head L extends crosswise, or from side to side, in the direction which the yoke tilts, and the back arm of the yoke has free play in said slot to the extent of one-hall of the tilting movement of the yoke. By this arrangement, when the shifter L, be ing at the extreme point of its movement at one side or the other, begins to move toward the other side, it presses the back arm of the pivoted yoke and causes the yoke to move, and the said movement continues gradually until the arms of the yoke assume a central vertical position. Now, the moment the yoke is tilted or moved beyond this central vertical position the gravity of the weight (1 comes into play and instantly throws the pivoted yoke against the stoppin c. The length of the slot in the frame or head L is sufiicient to allow the back yoke-arm, which occupies the slot, free play to the extent of the said throw.

The shank c of the shifter device is attached to a horizontal rod, 9, which moves endwise in staples or guides 71, and the end of the horizontal rod 5/ is bent to form a rigid projection, 2', which has position alongside of the driving spring A of the clock-movement. This rigid proiectioni serves as a trigger to throw the indicator into view, and also to cause the signal-gong I to sound.

It will be seen that when the driving-spring uncoiis or expands it will press against the triggcri and force it to one side, thereby moving the shifter L, yoke H, and sign-indicator G until the yoke assumes the central vertical position before mentioned, whereupon the signindicator G is exposed instantaneously.

The shifter L and indicator G, having been thrown by the action of the driving-spring A and trigger i, will be retracted or moved back again by the action of a spring, k, which is connected to the shank e of the shifter. The retracting-spring 7c will act the moment the driving-spring A is wound up.

Having described my invention, I claim and desire to secure by Letters Patent of the United States- 1. A wind-up indicator for clocks, having, in combination, a pivoted yoke, an indicatorsign attached to the yoke, the driving-spring of a clock-movement, a shifter device having a frame or head provided with a slot which is occupied by an arm of the pivoted yoke, and

7 a trigger, 'i, acted on by the driving-spring and connected with the shifter device, whereby the indicator-sign will be exposed instantaneonsly, as set forth.

2. A wind-up indicator for clocks, having, in combination, a pivoted yoke, an indicatorsign attached to the yoke, the driving-spring connected with the shifter device, and a re- 1 tracting-spring, k, connected with the shifter device, as set forth.

3. A wind-up indicator for clocks, having, in combination, a pivoted yoke, an indicatorsign, and a hammer attached to the yoke, a signal-gong, I, the driving-spring of a clockmovement, a shifter device having a frame or head provided with a slot which is occupied by an arm of the pivoted yoke, and a trigger, 'i, acted on by the driving-spring and connected with the shifter device, as set-forth.

In testimony whereof Iaflix my signature in presence of two witnesses.

' JAMES E. EHRLICH.
