GIAMBATTISTA DENEGRI, OF ZOAGLI, ITALY.

AUTOMATIC CRADLE.

SPECIFICATION forming part of Letters Patent No. 511,127, dated December 19, 1893. Application filed August I5, 1893. Serial No. 483,206. (No model.) Patented in Italy June 2S, 1893, No. 34,348-

To au whom it may concern:

Be it known that I, GIAMBATTISTA DENEGRI, of San Pietro di Rovereto, Zoagli, near Chivari, in the Kingdom of Italy, have invented a new and Improved Automatic Cradle, (for which I have obtained a patent in the Kingdom of Italy, No. 34,348, dated June 28, 1893,) of which the following is a full and exact specification.

My invention relates toa cradle, the rocking movements of which are produced by a clock-work actuated by a spring.

The objects of my invention are to produce such a cradle which can be manufactured very cheaply, which will be noiseless and efficient in action, and which will be simple and compact in construction'.

The particular features of novelty in my said improvement will be more fully hereinafter explained, and are illustrated in the accompanying drawings forming a part hereof, and to which attention is directed.

Figure 1 represents a side view of the improved cradle. Fig. 2 is a longitudinal section of the same. Figs. 3 and 4, are details, of the clock-Work.

In all of the above views corresponding parts are designated by the same letters of reference.

The ordinary cradle A, with its feet B B forming an are of a circle, is placed upon a wooden base C, which terminates at lthe rear end of the cradle in a wooden box D, containing the clock-work mechanism E, for actuating the cradle. Aplate F, directly beneath the bottom of the cradle A, forms a rigid connection between the two feet B B. Each of these feet is traversed by a guide pin G which is extended into an opening in the base C, where it is provided with a pin H, passing through the same. The guide pins G are placed so that, while preventing the cradle from being displaced relatively to the base C, they enable it to make the necessary rocking movement. To the foot B is rigidly xed a wooden shaft K which, extending to the rear,

is made for its main portion of wood, but the extremity which is fixed to the shaft K is made preferably of met-al and at the other extremity it is secured to the connecting rod M, by means of the leaf spring o, which does away with the necessity of a pivot. The upper end of the rod M engages with the crank portion of the drive shaft a, which in turning will impart a reciprocating movement to the rods M and L, causing the shaft II, to partially rotate,

back and forth, and giving to the cradle the desired rocking motions as will be understood.

The clock-work may be of the ordinary kind, but in order to render its movement as silent as possible I employ a governor of special form. To the extremity of the cranked shaft d is fixed a wooden disk b covered at its circumference with cloth c, Fig. d. This disk turns a wooden shaft d, to which are secured feathers e of fowls or other birds which extend radially so as to constitute the governor. At the part where the shaft CZ is in contact with the disk b it is provided with pins f, which engage with the cloth c, and serve to insure the transmission of power. One end of the shaft g, engages, at i, in the frame-Work of the clock-work mechanism. The other end is carried by a supporting rod h, which is supported by a leaf spring la W'hen the pins f, are to engage with the cloth covered surface `of the disk b, this leaf spring le, is to be held within a slotted support m, so as to be under tension, and effect the proper engagement. When, however, it is necessary to allow the clock-work mechanism to run down rapidly, the said leaf spring k, is to be shifted to a second slotted holder fa, so as to not be under tension, thereby throwing the pins f, out of engagement with the disk h. Upon the box D inclosing the mechanism is placed a handle P, and below the plate O a roller Q., which serve for enabling the automatic cradle to be easily moved about.

When the spring of the clock-work has once been wound up, or put under tension, it Will be suicient to push the cradle with the hand, in order to give it the automatic rocking movement to start it, and in like manner, if this movement is to be discontinued, it will be enough to stop the cradle for a incluent by hand.

Having now described and ascertained the nature of my said invention and in what man- IOC support h, and slotted supporting studs m and n, for said leaf spring 1c, said shaft g, carrying` pinsf, engaging with the cloth c, on the disk b, substantially as described.

In witness whereof I have signed this speci- 15 fcation in presence of two Witnesses.
