Application filed September 12, 1921.

T 0 all whom it may concern Be it known-that I, HERTHA JOAN NIsLE, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Cradles, of which the following is a full, clear, and exact description.

My invention relates toachilds bed of the type of construction commonly known as a cradle, and it consists in the combinations, constructions, and arrangements herein described and claimed.

An object of my invention is to provide a device of the character described, in which a body or receptacle in which a child may be placed is supported for oscillation, and means are provided for oscillating the body or receptacle. l

A further object of my invention is to provide a device of the character described, in which the direction of oscillation of the body may be varied at will.

A further object of my invention is to provide a device of the character described, in which the extent of oscillatory movement of the body may be varied.

A further object of my invention is to provide a device having means controlled by a time recording mechanism for determining the oscillations of the body or receptacle at a predetermined time.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims.

-My invention is illustrated in the accom panying drawings, forming part of this application, in which- Figure 1 is a side elevation of the device,

Figure 2 is an end view, partly in section, of a fragmentary portion of the device,

Figure 3 is an enlarged plan view of a fragmentary portion of the mechanism shown in Figure 2,

Figure 4 is a detail of another fragmentary portion of the device, and

Figure 5 is a detail of still another fragmentary portion of the device. I

In carrying out my invention, I provide a pair of supporting end members, having upright portions 1 equipped with legs 2 and fashioned adjacent to their upper ends to form downwardly inclined portions 3, provided with hemispherical sockets 4. The upright portions 1 are connected by a hori- Specification of Letters Patent. Patented June 20, 1922.

zontal frame member 5, whereby the supporting end members will be maintained in the position illustrated, when placed on a horizontal surface, such as the floor 6.

A body or receptacle in which the child is to be placed is indicated generally at 7 and comprises inclined sides 8--8, inclined ends 9-9, and a horizontal bottom 10. The body or. receptacle 7 may vary considerably in construction from that illustrated in the accompanying drawings, without departing from the spirit and scope of the invention, since it is only essential to my invention that a suitable receptacle adapted to receive a child be provided, whereby the child will be supported without danger of falling from the receptacle. In the form of the device illustrated, the body or receptacle is made up of a frame, to which is attached a foraminous material 11, such as netting or wicker work, to form the sides, ends, and bottom of the body, whereby proper ventilation of the body is assured. However, I do not insist upon this construction.

The ends'99 of the body or receptacle are equipped with eyelet members 12-12, which are attached thereto intermediately at their upper edges; These eyelet members are connected with the inclined portions 3 of the end supports by connectors 13--13 and 14 14, whereby the body or receptacle is suspended for a universal movement with respect to the supporting'end members. In

the form of the device illustrated, each .connector 14 is fashioned in a ball portion 15 at one end working in the socket 4c and maintained therein by a retaining ring 18 which has a threaded connection at 17 with the socket 4. Each connector 14: is formed with a socket 18 at its lower end adapted to receive a ball portion 19 which is integral with the connector 13. A retaining ring 20 having a threaded connection at 21 with the socket 18 contains the ball member 19 in the socket 18. The connector 13. is formed with an. eye 22 at its lower end engaged with the eyelet 12 at the adjacent end of the body or receptacle 7 The bottom 10 of the body or receptacle has secured thereto at its approximate center a plate 23 which is fashioned with a depending bracket arm 24 fashioned at its extremity into ball form, as at 25. The ball portion of the bracket arm is received within a socket 26 of a cross head 27, and is maintained therein between springs 28 and Q 29, the tension of the springs on the ball portion being adjusted by means of an ad- Justing screw 30. The latter is disposed in v is rigidly connected to or formed integrallya hub 32 mounted on a crank a threaded-bore 31' which extends through ,the wall of the cross head and opens into the socket 26, as shown. The cross head 27 and adjustably supported at one end on the horizontal frame member 5, being fashioned with a slot 39. A pivot pin, which is preferably a bolt capable of manipulation to lock the base plate 38 at a desired angle to the horizontal frame member 5, is pro ected through the slot-39 and through the horizontal frame member 5.

The base plate 38 also supports a motor 41 which has a drive shaft 42 on which is mounted a relatively small gear 43 in mesh with a relatively large gear 44. The latter is mounted on a shaft 45 journalled in a bearing 46 superposed on the plate 38. A relatively small gear 47 is mounted on. a

I shaft'and is in mesh with teeth 48 formed on a periphery of thecrank disk 35. The latter is substantially equal in diameter with the intermediate gear 44, whereby the crank disk 35 will be driven at a speed considerabl less than that of the drive gear 42.

g housing 49 encases the motor 41 and the gear train just described, being provided with a flange 50 attached to the base plate 38 by bolts 51 or like fastening means. The

pitman or connecting rod 31 extends through the opening 52 in the casing, as

shown.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood. When the motor 41 is actuated in the manner described,'the body or receptacle 7 will be oscillated in a manner simulating the rocking motion im lparted to a cradle supported on rockers. heextent of the oscillation 01' the body or receptacle 7 may be varied at will by positioning the crank pin 33 in different openings 34 through the crank. disk.

The direction of oscillation of the body or I receptacle may likewise be varied at will by swinging the base plate, which'is relatively long, about the axis of the pivot pin 40 to tacle. As a result, the body may be oscillated longitudinally, laterally,

or obliquely.

The extent of oscillation of the body or receptacle may be further adjusted by movthe base plate 38 with respect to the p1vot pm 40 to position the latter at various positlons alon the slot 39.

It is desirab eto providemeans for actuating the motor 41 automatically, without action on the part of the attendant for the child. With this object in view, an electric time recording mechanism 53 is supported on the end member 1, and is operatively connected as by means of an electrical conducting wire 54 with an electric switch 55. The time recording mechanism 53 and the switch 55 are provided with conductors 56 and 57 respectively, by means of which they may be connected with the motor operating circuit. The time recordin mechanism 53 and the switch 55 are or inary in construction. It will therefore be understood that the time recording mechanism 53 may be set to open or close the motor operating circuit at given times. Consequently, the oscillation of the bod or receptacle 7 may be begun or steppe at given times,

without an actionon' the part of the attendant being required.

I claim:

of oscillation of the receptacle.

' 3. A device of the character edescribed comprising a receptacle supported for oscillation, a mechanism having a reciprocating pitman, said pitman being arranged to engage said receptacle to oscillate the latter, and a base for supporting said mechanism,

said base adapted to be moved relative to said receptacle to vary the direction of oscillation of said receptacle.
