ROCKING CRADLE OR SIMILAR ROCKER.

SPECIFICATION forming part of Letters Patent NO. 603,002, dated April 26, 1898.

Application filed July 29, 1397. Serial No 646,278. (No model.)

To all whom it may concern:

Be it known that I, JOHN ALLRED, acitizen of the United States, residing at Rockingham in the county of Richmond and State of North Carolina, have invented certain new and useful Improvements in Rookie g Cradles or Similar Rockers, of which the following is a full and complete specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to baby-rockers; and the object thereof is to provide an improved automatic apparatus for rocking cradles and similar rockers; and with this and other objects in view the invention consists in the construction, combination, and arrangement of parts hereinafter described and claimed.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which- Figure 1 is a side view of one end of a rocker provided with my improvement, and Fig. 2 an end view thereof.

In the drawings forming part of this specification the separate parts of my improvement are designated by the same numerals of reference throughout both the views, and in the practice of my invention I provide a cradle or other rocker 5, having a head or end board 6, which is provided with the usual legs 7, to which is secured the rocker 8.

In constructing my improved rocking apparatus I provide a plate 9, which is secured to the end plate or board 6 and near the top thereof, and I also secure to the top of said end plate or board a strong metal strip or yoke 10, which is carried outwardly and downwardly to form an arm 11, as shown in Fig. 1, and acts in connection with the plate or board 9 to support the operative mechanism, which -is of the following construction: Mounted between the plate or board 9 and the depending arm 11 of the yoke 10 isashaft 12, on the inner end of which is a spring-drum 13, one end of the spring of which is secured at 14c to the plate 9 and the other end to the shaft 12. Mounted adjacent to the drum 13 is a gearwheel 15, which is revoluble on the shaft 12, and secured to said shaft is a ratchet-wheel 16, and the gear-wheel 15 is provided with a spring-operated pawl 17, which operates in connection with the ratchet-wheel 16, and the spring 18, by which the pawl is held in connection with said ratchet-wheel, is secured to the gear-wheel 15.

The shaft 12 is provided with a head 19, by which the drum is wound, said head being provided with a ring or handle 20, and below the shaft 12 is'a shaft 21, on which is mounted a pinion 22, which operates in connection with the gear-wheel 15, and the shaft 20 is also provided with an escapement-wheel 28, and I also provide an escapenlent 24, which is secured to a transverse lever 25, to each end of which is pivoted aleg 26, each of which is provided with an adjustable extension 27, and said legs and said extensions are provided with longitudinal slots 28, through which passes a set-screw 29, by means of which the extensions of said legs may be adjusted thereon, and each of said extensions passes through a keeper 30, secured to the rocker 8.

The extensions 27 of the legs 26 are provided with heads 81, and the lever 25, with which the escapement 24 is connected, is mounted on a shaft 32, and connected with one end of the lever 25 is a crank-rod 33, which is connected with a crank-shaft 34, which is mounted in the upper end of the yoke 10, and the lower side of the lever 25 is provided with a semicircular notch or recess 85, through which passes a rod or shaft 36, which forms a part of the supporting-frame and also regulates or limits the movement of the lever 25.

The operation will be readily understood from the foregoing description when taken in connection with the accompanying drawings and the following statement thereof.

The spring-drum is first wound up in the usual manner, and when this has been accomplished and the said drum begins to unwind the gear-wheel 15 will revolve with the shaft on which the drum is mounted by reason of the spring-operated pawl 17, which is mounted on said gear-wheel and which operates in connection with the ratchet-wheel 16. The shaft 21 will also be revolved by said gearwheel and with it the escapement-wheel 23, and the escapement 2t will be operated so as to give the lever 25 an oscillating motion. This movement of the lever 25 will cause the legs 26 to move up and down alternately, and the lower ends thereof, or of the extensions 27, will be alternately forced upon the floor and the movement will rock the cradle, as will be readily understood. The crank-shaft 34 is also revolved by the crank-rod 33, and the inner end of said shaft may be extended and a fan attachment maybe connected therewith, if desired. This movement of the parts will be continued until the spring-drum is unwound, and, as will be understood, the said drum may be wound up as often as necessary or whenever desired.

My improved automatic rocking device for,

cradles is simple in construction and operation and perfectly adapted to accomplish the result for which it is intended, and it is evident that changes in and modifications of the construction herein described may be made without departing from the spirit of my invention or sacrificing its advantages.

Having fully described my invention, 1 claim as new and desire to secure by Letters Patent 1. In a mechanism for rocking cradles or other'rockers, the combination with a plate and a yoke adapted to be secured to the cradle or other rocker, of a revolublc shaft mounted in said plate and said yoke, a spring the ends of which are secured respectively to said shaft, and to said plate, a ratchet wheel rigidly mounted on said shaft, a gear-wheel loosely mounted on said shaft, a pawl on said gearwheel whereby it may be rotated in one direction only with said ratchet, asecond shaft,

of which are secured respectively to said shaft and to said plate, a ratchet-wheel rigidly mounted on said shaft, a gear-wheel loosely mounted on said shaft, a pawl on said gearwheel, whereby it may be rotated in one direction only with said ratchet, a second shaft. a pinion mounted thereon, an escapementwheel, a lever, an escapement, whereby in conjunction with said escapement-wheel, said lever is oscillated, legs pivoted to said lever whereby the energy of said spring may be exerted on the fioor to oscillate the entire structure, extensions to said legs, said legs and said extensions being provided with slots adapted to register, and a set-screw whereby the said legs may be lengthened or shortened, and the extent of oscillation of said structure regulated, substantially as described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of the subscribing witnesses, this 27th day of July, 1897.

hi JOHN ALLRED.
