AUTOMATIC CLOCK-WINDING MECHANISM.

SPECIFICATION forming part of Letters Patent No. 427,381, dated May 6 1890.

Serial No. 328,356- (No model.)

To aZZ whom it may concern:

Be it known that I, OTTO URBAN, of Nagy Kikinda, in Austria-Hungary, have invented a new and useful Self-Acting lVindin g Device for Clocks (pendules,) of which the following is a specification, reference being had therein to the accompanying drawings.

My object is to provide a winding mechananism which will become automatically inop- IO erative when the spring or weight is completely wound, and also to utilize the movement of a door in opening and closing as the motive power.

In the drawings, Figure l is a side elevation of the winding mechanism with the parts in position for the winding operation, the weight being only partially wound up. Fig. 2 is a similar View with the weight entirely wound up and the partsin inoperative condition, this view showing also the connection to the door. Fig. 3 is a plan View 011 line a 03 of Fig. 2. Fig. 4 is a detail view of the actuating device at the door. Fig. 5 shows the operating-pawl detached.

The winding-arbor o is of ordinary construction and is connected with a motive spring (not shown) in the usual manner, or with the weight g by means of the cord r and sheave *r. ()n this arbor is fixed rigidly a ratchet 7b, which is engaged by an operating-pawl f,

pressed into contact with the teeth thereof by spring f. This pawl with its spring is carried by a rocking disk 0, loosely journaled on the arbor. The operating-cord s is connected 3 5 with the rocking plate at c, and when pulled upon will partially rotate said plate, which action will be transmitted to the arbor through the pawl and ratchet f h, thus effecting the winding of the spring or cord 0" with its attached weight. After each action and before the winding is completed the rocking disk is returned to normal position by means of the weight p,which is conn eeted thereto by means of lever Z, pivoted at Z, and cord p, passing over a sheave 2'. This weight applies a tension to the cord 13, which thus effects the retraction of the rocking disk for a new action. If, however, the effect of the weight 1) is removed from the cord p',the rocking plate will not be retracted, and subsequent movement of the operative cord will be without effect upon the winding mechanism. This result is desired when the winding is completed and is secured by means of the lever Z, which has a portion 772 in the path of the pulley r, so that just before the weight has been wound up su [liciently and during the final winding action the said pulley will strike the portion 071, raise the lever and weight 13, and thus relieve the retracting-cord p of tension, preventing the immediate return of the rocking plate for a new operation. This action is illustrated in Fig. 2, the cord p being slack, unaifect'ed by the weight, and the rocking plate remaining in its moved position. The movement of the operating-cord s is limited, as will hereinafter be seen, and as long as the rocking plate remains in this position the parts will not be affected by subsequent pulls upon the same. The pawl f is pivoted with an arm e 011 the front side of the rocking plate, which arm is acted upon by a lever (Z, pivoted on the plate. As the mechanism runs down, the rocking disk moves around with the ratchet, because the pawl remains in engagement therewith, Fig. 2, and the disk thus gradually returns to normal position, and the purpose of the lever (Z and arm 6 is to arrest the disk when it reaches normal position by disengaging the pawl from the ratchet, which is effected by the lever (Z striking a pin 0L, after which the works may continue to run down without moving the rocking disk,which is now in position for another action. i

The rope s is actuated by the opening and 8 3 closing of a door in the following manner: It is connected with a rope Z) by a turn-buckle s, for adjustment, which rope passes around sheave u and is connected to a lever b 011 a rock-shaft a, held in bearings just above the door. This shaft has also a bent arm formed with two inclined surfaces a a As the door is opened and closed, it bears upon these surfaces and thus raises the arm, rocks the-shaft, and pulls upon the operating-rope to turn the rocking disk. It will be obvious that when the disk is at the extreme limit of its movement, as in Fig. 2, the operating-rope will then be slack and subsequent movements of the door will not affect the parts until they return toward normal position.

I claim as my invention- 1. In combination, the Winding-arbor, the ratchet thereon, the pawl, the disk carrying the same, the operating-rope s,extending from the disk in one direction, the retracting-rope 1), extending from the disk in the opposite direction and having connection with the Weight 19, the motor-Weight q, and the lever Z in the path of the weight to be operated thereby, the said lever Z being arranged to lift the retracting-weight P when the mechanism is wound, substantially as described.

2. In combination, the winding-arbor, the ratchet thereon, the pawl, the disk carrying \Vitnesscs:
