1 Claim.

This invention relates to a cradle, and more particularly to a rocking cradle for infants.

A primary object of this invention is the provision of an improved rocking cradle having metor means associated therewith for imparting a rocking motion.

An additional object of the invention is the provision of guide means associated with the frame of such a cradle, whereby rotary motion of a. pulley driven by the motor is translated to linear rocking movement of the cradle.

Another object of the invention is the provision of such a device which is sturdy and durable in construction, reliable and efiicient in operation, and relatively simple and inexpensive to manufacture and assemble.

Other objects will in part be obvious and in part be pointed out as the description of the invention proceeds, and shown in the accompanying drawings, wherein there is disclosed a preferred embodiment of this inventive concept.

In the drawings:

Figure 1 is a side elevational view of one form of cradle embodying features of the instant invention.

Figure 2 is a sectional view taken substantially along the line 22 of Figure 1, as viewed in the direction indicated by the arrows.

Figure 3 is a sectional view taken substantially along the line 3-3 of Figure 1, as viewed in the direction indicated by the arrows.

Figure 4 is a sectional View taken along the line 4-4 of Figure 1, as viewed in the direction indicated by the arrows.

Figure 5 is a sectional view taken substantially along the line 55 of Figure 1, as viewed in the direction indicated by the arrows.

Similar reference characters refer to similar parts throughout the several views of the drawmgs.

Referring now to the drawings in detail, the device of the instant invention comprises a main frame including four spaced uprights l0, the two at either end of the frame being connected by transverse members ll, between which. members extends a longitudinal supporting beam I2. The cradle is comprised of four uprights l3, a base I4 upon which the infants bed is adapted to be positioned, and guard rails I5 to preclude the infants falling from the cradle. The uprights I3 extend a substantial distance below the bottom 14-, and are pivotally connected, as by pivots HS, to supporting members I! extending from the lower ends of the uprights l3 to the upper ends of the uprights In to which they are pivotally connected, as by pivots l8.

Secured to the side of the beam I2 at an intermediate point is an electric motor 20 which drives a pulley 2|, which in turn, through a belt 22, drives a pulley 23 mounted on an axle 24 extending through the beam l2. Pulley 24 has pivotally secured to a peripheral point thereof, as by a pivot 25, a pitman 2B, the opposite end of which is secured, as by a pivot 21, to the under side of the base I4 of the cradle.

Transversely extending bars 28 are secured to the top of the beam l2 and provided at their extremities with pivots 28, movable in slots 30 in the extremities of levers 3|, the opposite ends of which are in turn pivotally secured, as by pivots 32, to the under side of base 14.

From the foregoing, it will now be seen that when the motor is energized to rotate the pulley 23, the pitman 26 will impart transverse rocking movement to the cradle, the movement being limited against longitudinal play by means of the guide bars 28, and their associated pivotal connections in the base of the cradle.

Thus, there is herein provided an improved rocking cradle which accomplishes all the objects of this invention, and others, including many advantages of great practical utility and commercial importance.

As many embodiments may be made of this inventive concept, and as many modifications may be made in the embodiment hereinbefore described, it is to be understood that all matter herein is to be interpreted. merely as illustrative and not in a limiting sense.

I claim:

In a cradle and cradle frame assembly including an elongated, rectangular cradle, an elongated cradle frame having a length greater than the length of the cradle, upstanding ends including corner posts higher than said cradle, and a longitudinal beam extending between and connected at its opposite ends to th respective frame ends, respective links extending from said corner posts near the upper ends of the latter to said cradle near respective bottom corners thereof suspending said cradle in said frame for swinging movements from side to side, and motor driven means mounted on said longitudinal beam and connected to said cradle for imparting reciprocating, lateral swinging movement to the latter, means restraining said cradle against longitudinal and turning movements comprising, two bars secured to and extending perpendicularly across said longitudinal beam near respective ends of said cradle, respective links extending between the ends of said bars and the adjacent corners of said cradle and means pivotally connecting said 4 REFERENCES CITED The following references are of record in the file of this patent:
