FRIEDRICH ALROTH, OF PLAUEN-DRESDEN, GERMANY.

SELF-MOVING CRADLE.

Specification of Letters Patent.

Lratented March 6, 1906.

Application filed August 5, 1905. Serial No. 272,898.

To aZZ whom it may concern:

Be it known that I, FRIEDRICH ALRorn, a citizen of the Empire of Germany, residing in Plauen-Dresden, in the Empire of Germany, have invented certain new and useful Improvements in Self-Moving Cradles, of which the following is a specification.

The cradles at present in use, in which a rocking movement is imparted to the cradlebody, are in the opinion of medical authorities injurious to the health of the child, having a particularly detrimental effect upon the brain. The well-known baby-baskets also have the defect that when the infant needs to be quieted it has to be removed, it being impossible to produce a movement of the basket which will soothe the child The object of the present invention is to obviate the above-named defects and to provide a self-moving cradle in which a horizontally-reciprocating movement in either a longitudinal or transverse direction is imparted to the cradle-body.

A further object of the invention is to provide simple and efficient mechanism for automatically actuating the cradle-body.

The novel features of the invention will hereinafter appear and finally be pointed out in the claims.

In the accompanying drawings, in which corresponding parts are designated by the same reference characters throughout, Figure 1 is an end elevation of the improved cradle, the casing for the actuating mechanism being shown in vertical transverse section and the cradle-body being positioned in such a manner as to be reciprocated transversely. Fig. 2 is a top plan view of the motion-transmitting mechanism, the cradlebody and the cover of the casing being removed and Fig. 3 is a detail view of a portion of said transmitting mechanism.

Referring to the drawings, D indicates the casing in which the actuating mechanism of the improved cradle is housed and upon the top or cover of which the cradle-body m reciprocates. The casing D is composed of two parts, as shown in Fig. 1a lower part (V, in which a suitable motor A (illustrated as a spring-motor) is contained, and an upper part d, which houses the motion-transmitting mechanism and to which legs or other suitable supports for the casing D are attached, as show The motor A embodies an upright shaft a, which rotates in step-and-neck bearing in the bottom of the part or box d wardly into the part d, where it has keyed thereto in any suitable manner a crank b, at the end of which an upwardly-disposed wristpin 0 is arranged. Said wrist-pin engages a horizontally-disposed slotted bar (I, which is fixed to a shaft e, extending transversely of the box (1 and axially slidable in bearings f therein, said box being provided at either side with apertures through which said rod may extend when at either end of its reciprocating movement, whichis'eflected by the rotation of the wrist-pin c, as will be readily understood. In the embodiment illustrated the shaft e is journaled adjacent one end of the casing 61.

Pivoted at one end, as shown at B, to a pin at the end of the casing (1 adjacent the shaft d is a lever i, which extends inwardly through a slot t in said casing, as shown in Fig. 2, and is provided intermediately with a slot y, engaging an upright pin h, extending between the upper and lower side faces of a boxing g, carried by the shaft 6, adjacent the slotted bar d. The lever 71 is also provided with a slot .2 at its inner end, which engages an upright pin it, extending between two spaced superposed parallel plates is, which constitute a coupling, from which upright rods Z extend upwardly, as shown in Fig. 1. At the upper ends of the rods Z, which operate in transverse slots 96 in the cover of the part (2, are placed cross-pieces 14, provided with terminal rollers n, movable over said top or cover. The uprights Z and crosspieces n constitute a carriage upon which is supported in any suitable manner the body m of the cradle.

A handle 0 serves to wind up the motor A and a hand-wheel p to stop the same when desired.

The operation of the improved cradle is as follows: The motor having been wound by means of the handle 0 and the wheel 19 released the motor is started, transmitting rotary motion to the crank b in the direction inand extends updicated in Fig. 3. Reciprocating motion is then transmitted to the slidable shaft 6, which passes at either end of its movement through the apertures in the part d. The reciprocating motion of said shaft thus serves to rock the lever 01 upon its pivot B through the medium of the pin h cooperatingv with the slot y, and the inner end of the lever '5 therefore describes a comparatively long arcuate movement, carrying with it the coupling member 7c and the carriage constituted by the cross-pieces u and rollers n. As the body m is secured to said carriage a horizontal reciprocating movement is thus imparted to the same. As shown, the body m is adapted to be reciprocated transversely; but it is obvious that by shifting the same on itslrlzarriage it may be reciprocated longitudina y.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent 1. In a self-moving cradle, a casing, a le ver pivoted adjacent one end of said casing and extending into the same, mechanism in said casing for rocking said lever, a carriage attached to the inner end of said lever, and a cradle-body mounted on said carriage and movable over the top or cover of said casing.

2. In a self-moving cradle, in combination,

a casing, an aXially-slidable shaft therein, a

4. In a self-moving cradle, in combination, an aXially-slidable shaft, means for reciprocating the same, a pivoted lever operable by said shaft, a carriage attached to the free end of said lever, means for guiding said carriage, and a cradle-body mounted on said carriage.

' 5. In a self-moving cradle, in combination, an aXially-slidable shaft provided with a pin, a lever pivoted adjacent said shaft and having a slot engaging said pin, a cradle-body attached to the free end of said lever, and means for supporting and guiding said body.

6. In a self-moving cradle, in combination, a casing, a transversely-disposed axially-slid able shaft mounted in said casing adjacent one end thereof, means for reciprocating said shaft, a lever pivoted adjacent the end of said casing and rockable by said shaft, a carriage carried at the free end of said lever and em bodying rollers movable on the top or cover of said casing, and a cradle-body mounted on said carriage. I

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing Witnesses.
