l .To l1f/ZZ whom it may concern:

Be it known that I, BERTRAM SARRETT, -a

l citizen of the United States, residing at Camden, in the county of Benton and State 4of l Tennessee, have invented certain new and useful Improvements in Cradle-Rocking Attachments, of which the following is a specification.

The object of my invention is to provide an improved construction of automatic rocking attachment for cradles so arranged that it will fit cradlesof different lengths and provided with means' whereby more or less power 'may be imparted from the motor mechanism to the cradle whenever desired.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for eHecting the result reference is to be had to the following description and accompanying drawings, in which- Figure 1 is an end view of my invention. Fig. 2 is a top plan view4 of the attachment. Fig. 3 is a side elevation. Figs. 4 and 5 are detail views illustrating the means for 'attaching the cradle-rockers to the supportingframework.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Referring to the drawings, the referencenumeral 1 designates the supporting-framework, which comprises two end bars 2, designed to directly support the rockers of a cradle, and two side bars or lon 'tudinal bars 3, which are made in. extensib e sections 3 and 3b, adjustabl connected together, so that the framework may be extended to suit cradles of diiierent sizes. In the present instance the sections 3EL of the side bars have rigidly secured thereto metallic or wooden plates 4, which extend inwardly to form upper and lower guides 4a, and the ends of said sections are secured together by spaced-apart and lower transverse braces 5, as shown in the drawings. The sections 3b are connected together at their ends by a transverse brace 6 and are fitted to slide between the transverse braces 5 and between the flanges or guide members 4it of thel plates 4. Adjusting1 or clamping screws 7 extend through eit er one or both of the sections 3a and are designed to impinge against the sections 3b, so as to maintain the two sections in their different adjusted positions. A

date rockers o diiferent. curvatures.

i The motor vmechanism (designated 8) is mounted in a casing 8a of any design secured to oneside of the framework, and preferably the motor mechanism is located at the middle of the framework longitudinally considered. The motor mechanism 8 is referably of the spring type, the spring 9 o which is intended to be wound up by means of a hand-lever 10. y Through a suitable train of gearing, which includes master-wheels 11 and `governor-shaft 12, providedvwith goveiner-balls 128L and a counter-shaft 13, provided with pmions 14 and 143,'meshin respectlvely, with the master gear-whee and t e governor-shaft, motion is imparted from the spring .to the counter-shaft 13, and the latter carries at one end an eccentric 15.

I-he eccentric 15 is provided with two socketapertures 16, which are different distances from its center, as shown in the drawings. A

detachable crank-pin 17 is designed to enter l either one of the said socket-apertures and is intended to secure to said eccentric one end ofa pitman 18. The other end of said pitman 1s detachably secured to one end of the rockers 19 of the cradle 20. Preferably the pitman is extensible-that is, it is" constructed in two sections 18a and 18", arranged to telescope and be held at different extensions by means of a set-screw 18C. By this means the pitman ma be.extended to accommllli- T e counter-shaft which carries the eccentric is preferably provided with ay ratchet-wheel 21, with which a hand-operated pawl 22 is adapted to engage 'in order to stop the motor mechanism atl any desired time-for instance, when the child in the cradle falls asleep. The brake mechanism constituted by the ratchet and pawl mechanisms is not indispensable, however, as the eccentric and pitman themselves may be utilized to bring the cradle to a standstill by merely stopping the cradle with the pitman on the center. Then should the child awake and move or roll from one side of the cradle to the other it `will so shake the cradle as to throwI the pitman off the center and again start the mechanism. By this means the 4startingis rendered automatic in a sense in that it does not require personal supervision or any manipulation to start it.

From the foregoing description, inconnection with the accompanying drawings, it will be seen that I have provided a cradle attachment which will mechanically rock a ICO cradle whenever desired and which will ac' commodate itself to cradles of different -sizes and diierent curvatures of rockers. The different a ertures in the eccentric are provided so that more power may be given, if desired, by attaching the pitman to the eccentric nearthe center of the same. This may be important when the child grows and lbecomes so heavy that the mechanism will cured to the end bars of the supporting-` frame by means of headed studs 25, secured lto the rockers and designed to enter keyhole-slots 26 in lates 27 secured to and pro-v jecting upward y from the end bars of the supporting-frame. It will be seen that the slots widen at their upper ends, so that the rockers may be detached readily from the sup orting-rame by moving them upwardly to s 'de the studs upwardl in the sots and then sprin g the plates o the studs.

While i? drawin s show the motor located at the left-han end of the machine, as

shown in Fig'. 1,4 it is of course to be understood that my invention is not limited to this exact location of. the motor, as it may beland preferably is located at the right-hand side of the framework.

Havin thus described the invention, what is claime as new is A device ofthe character described comprising a framework constituted 'of end bars desi and ongitudina bars constructed in sections respectively connected to ,the endbars, two of said sections being provided at their ends ed to Sup ort the -rockers of a cradle'.

with upper and lower transverse braces embracing the other lsections and being also provided near said ends with inwardlyex j tending upper andlower plates constituting guides and clamping-screws designed to'extend inwardly to impinge against the yother sections, pglatessecured to the end bars of the framewo and extending upwardl therefrom each of said plates being provi ed with a keyhole-slot, a cradle embodying rockers provided with headed studs designed to :be

lnserted through the enlarged portions of said slots whereby they may be retained and guided therein, a motor mechanism supported on said framework,` and a detachable and adjustable pitman connection between one of the rockers of the cradle and said motor mechanism. o

In testimony whereof I ai'liX my signature in presence of two witnesses.

' BERTRAM SARRETT.
