IMPROVEMENT lN TOY CLOCKS.

Specification forming part of Letters Patent No. 191,645, dated August 28, 1877 application filed January 30, 1877.

To all whom it may concern Be it known that I, EDWARD W. BRIDGE, of the city and county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Toy Clocks, which improvement is fully set forth in the following specification and accompanying drawings, in which- Figure l is a front view of the clock embodyin g my invention. Fig. 2 is a similar View of the interior thereof. Fig. 3 is a rear view. Fig. 4 is a central vertical section of the mechanism.

Similar letters of reference indicate corresponding parts in the several figures.

My invention consists of a toy of the order of a clock, in which the ticking sound thereof is closely imitated.

For this purpose I employ an escapement movement which is retarded by a pendulum, the operation of which is hereinafter more fully described.

Referring to the drawings, A represents the center post, which carries hands B, and is mounted on a suitable frame, 0. D represents a spring, one end of which is secured to the frame 0, and the other end is secured to and winds on the center-post A, the rear end of which is properly squared for application of the winding-key. To the post A is secured a ratchet-Wheel, E, and on the same is loosely fitted an escapement-wheel, F, to which rotation is imparted from the spring by means of a spring-pawl, a, pivoted to the escapement- Wheel, and engaging with the ratchet E in one direction, said pawl riding freely over the ratchet during the winding operation in the reverse direction. G represents the palletarm, whose axis is on the frame 0, and it engages with the escapemen t-wheel and operates therewith, as is well known.

From the rear of the axial shaft of the pa let-arm there is secured the pallet-lever which may consist of an open frame, disk, r bar, and it extends vertically at the rear f the frame 0, the opening in the lever permitting the insertion of the key on the center post. 5

The lower end of the lever is connected b a slot and pin to the pendulum J, which s pivoted near its upper end to the frame 0. 9

The operation is as follows: When the clock is wound the escapement is operated, an swinging motions are imparted to the lev r H. As these motions would otherwise e quick, and the clock soon run down, the pen ulum is employed as a detaining or retardii device, for when the lever swings to the le t the pendulum-bob swings to the right, an vice versa; consequently the lever H is du restrained, and the rotation of the center-p0 t properly regulated, whereby the hands B move sufficiently slow over the dial of tli clock. E

It will be noticed that the ticking of a timiakeeping clock is closely imitated, and t 'e hands are moved, whereby the object of tile toy is attained.

Having thus described my invention, \vh t I claim as new, and desire to secure by L; ters Patent, is- 1 A toy clock in which the power of a spril g is communicated from the center-post to t e escapement and restrained by a pendulu which is connected to apallet-lever suspend d from the axis of the pallet-arm, substantially as stated.
