All cradles now in use uire the mother or nurse to keep constan rocking the cradle, in order to soothe the by and. cause it to fall 06 to sleep; This is an annoyance 5 to which most mothers and nurse maids 16 Another purpose is to provide, in a cradle of this kind means consisting of a small motor carried by the base frame and operatively connected with the moving cradlesection at a point through the top ofthe base 2 frame in order to impart movement to the cradle roper.

Anot er purpose is to provide in a cradle, a base frame having end pieces with 'des thereon including rollers on the c e to 25 engage the guides above and below their edges, together with guard rails, to not only prevent any binding of the rollers but also prevent any excessive endwise movement of the cradle, the guard rails engaging the 80 spindles on which the rollers are mounted. It is to be understood that the particulars herein given are in no way limitative, and that while still keeping within the scope of the invention, any desired modification of details and proportions may be made in the construction of the appliance according to circumstances.

The invention comprises "further features and combination of parts to be hereinafter set forth, shown in the drawings and claimed.

In the drawings Figure 1 is a view in side elevation of the improved cradle with its dominant supporting frame broken away at its center with the bearing 7 in section, and the padded housing portion 3a of the frame likewise in section.

Figure 2 is an end view of the same with the padding 8a in section.

Figure 3 is a plan view, clearly showing the means for imparting transverse reciprocating movements to the cradle.

Figure 4 is a rspective view of the ide tracks and e guard rails, showing ow the cradle is mounted thereon.

Referring to the drawings, 1 identifies a base frame, which may be any size or any shape, which consists of an upper bed rtion 2 with the dependi legs 3, inclu a supportingshelf 4 on w ich a conventiona type of motor 40 is supported, the motor having the usual wires or leads connected thereto, the other end of the lead having a conventional'type of plug 6 for e gement in a socket (not shown) to transmit electric current to the motor.

vMounted in a sleeve bearing 7 of the to of the base frame is a shaft 8 provided wit a worm wheel 9, which meshes with a worm 10 on the motor shaft. In this manner powor is transmitted from the motor to the shaft 8, the lower end of which is mounted in a bearing 12 on the shelf. The upper end of the shaft 8 has a crank arm 13, connected at 14 to a link 15 which in turn is pivotally connected to a transverse bar 16 carried by the cradle 17.

Obviously when the shaft 8 is rotated through the medium of the worm and worm gear the crank arm on the shaft rotates. and imparts movement to the link which in turn will transmit reciprocating movements to the cradle.

Due to the transmission of power from the motor to the shaft 8 through the medium of the worm gear and worm the movements of the cradle are relatively slow, having a soothing effect on the baby rather than causingany excitement thereof, the tendency bein to put the baby to sleep.

e motor possibly mayproduce a humming' noise when in o eration though it may be well lubricate and in order to deaden this noise to some extent the base frame may be closed in, that is from the shaft up, as shown, the interior of the enclosure of the base frame may be conventionally padded, at 3a acting to deaden the noise of the motor. However there will be 0.

just enough of the noise escaping, such as rollers well as avoiding undue endwise will tend to soothe the baby andcause'it to movement of the cradle.

In testimony whereof he afiixes his. sigfall off to sleep.

' or tracks 22.

The base frame is provided at its opnature.

posite portions with lateral extension arms 19, whlch support end ieces 20. The extension arms 19 and the egs 3 are connected by bars 30.

Mounted on the arms 19 are brackets 21, and connectin the brackets are guide rails ounted on the opposite ends of the cradle upon spindles 23a are rooved rollers 23, metal bars 24 supporting the s indles. The grooved rollers 23 encga e t e upper edges of the guide rails, an epending from the bars (which carr the spindles) are arms 25, carrying groove roll-' ers 26 which ride on the underedges of the guide rails or tracks. By this arrangement of grooved rollers and ide rails or tracks the cradle is ided 1n its reci rocating movements an by means of tiie latter grooved rollers, the former grooved rollers 23 are prevented from disengaging. the upper edges of the guide tracks or rai Secured to the adjacent faces of the end pieces of the base frame are guard bars 27, the lon itudinal side faces of which assume re atively close positions to the spindles of the rollers 23, acting to prevent any bindin of the rollers on the guide tracks as we as preventing undue endwise movement of the cradle.

The invention having been set forth, what is claimed is:

In a cradle as set forth, the combination with a dominant supporting frame having an upper bed portion with supporting legs and provided with a lower sound proof housing portion, said upper bed portion having extension arms. extending laterally in opposite directions from the bed portion, of tracks with means operatively supporting the tracks on the extension arms transversely thereof, a cradle with upper and lower grooved rollers at its opposite ends for. engagement with the upper and lower edges of the tracks, whereby the cradle may reciprocate laterally, a driven member mounted centrally of the upper bed portion of the frame, means operatively connecting the cradle and the upper end of the driven member, whereby as the member operates movement may be imparted to the cradle, means on the interior of the housing portion of the frame and connecting with the lower end of and imparting movement to the driven member, upstanding pieces rising from the ends of the extension arms, guard bars mounted upon the upstanding pieces with certain of their longitudinal side faces assuming relatively close positions to the pintles of the upper grooved rollers of the cradle, acting to prevent any binding of the
