G. W. GOODING. ROCKING DEVICE. APPLICATION FILED MAY 13, 1908.

PATFNT (EFFIC GEORGE WASHINGTON GOODING, OF SEATTLE, WASHINGTON.

ROCKING DEVIGE.

T all whom it may concern:

Be it known that I, GEORGE NAsinNGToN GOODING, a citizen of the United States, residing at Seattle, in the county of King and State of Washington, have invented a new and useful Rocking Device, of which the following is a clear and concise specification.

My invention relates to a rocking device for cradles in which the elements may be concealed from vision thus providing a device which may be substantially inclosed and preventing the working parts thereof from becoming damaged or broken.

My device also relates to a governing means for giving the cradle a uniform motion while rocking to increase the efliciency of the construction of the device hereinafter more fully set forth.

The objects of my invention are to provide new and compact device to impart a rocking motion to cradles; to provide a means for governing the rocking device to cause uniformity in the motion of the cradle; to provide a stopping and starting device for the motor. I accomplish these as well as minor objects by the construction now preferred by me and illustrated in the accompanying drawings in which Figure 1 is a section of the cradle showing the disposition of my device; Fig. 2 is a bottom view of the governing toggle and parts operated thereby; Fig. 3 is a plan view of the preferred form of motor Fig. 4 is an elevation of the motor; Fig. 5 is a section of a modification of the cradle in which the receiving part thereof is pivotally connected to the rockers; Fig. 6 is a diagrammatical view of the motor showing the extreme position of travel.

Similar reference numerals refer to similar parts throughout the several views of my device as illustrated in the accompanying drawmgs.

I have provided a frame work 1 adapted to support the moving parts of the motor 2 which is preferably provided with a spring operated train of gears comprising the main gear 3 journaled on the shaft 4 which is rigidly secured to the sprocket 5. The spring 6 is rigidly secured to said framework 1 and also to said shaft 1 thus driving said sprocket 5 which engages the pawl 7 which is pivotally connected to said gear 3 which intermeshes with the pinion 8 secured to the shaft 9 and which drives the gear 10 and pinion 11 secured to the shaft 12 which is Specification of Letters Patent.

Application filed May 13, 1968.

Serial No. 132,70 1.

adapted to drive the gear 13 and pinion 14 secured to the shaft 15 and which is rigidly secured to the arm 16 having the weight 17 slidably mounted thereon and connected to the link 18 which is secured to the toggle 19 operating the friction members 20 and 21 which grip the stationary projection 22 whicn is rigidly secured to the framework 1. Said weight 17 is restricted from radial travel due to centrifugal force by means of the spring 23 secured thereto and to the guide member 2a which is slidably adjusted relative to the arm 16 by a screw 25 regulating the tension. of said spring 23; thus it is obvious that by overcoming said spring, as

the velocity of said weight increases, the

toggle operates and applies frictional resist ance to the stationary projection 22. To stop said arm from rotating I have provided a checking device 26 comprising a spring 2. engaging the under surface of said arm 16 prior to striking the stop 23 which is pivotally and slidably mounted on said framework 1 by the slot 29 and screw 30 which also serves to hold said spring 26 in position. Said stop is relieved by a spring 31 which compresses by reason of the kinetic energy of said weight 17. Then it is desired to permit the motor to run, said checking device is swung to the position indicated by dotted lines in Fig. 3 by pulling on the rod 32 which is accessible from the exterior of the cradle.

The cradle may be advantageously constructed by providing a bottom piece 33 to which the motor 2 is secured and a horizontal partition 34 which acts as the floor of the cradle and also protects the motor. The

end walls

35 and 36 are secured to said bottom piece 33 and horizontal partition 34. It is obvious that by having the side walls rigidly secured to the inner walls which are continued downwardly to form the

rockers

39 and 10 if a weight is placed to one side of the cradle unless the motor is made sufficiently large the cradle will not rock uniformly. In Fig. 5 I have shown the bed 411 pivotally mounted to said

end walls

35 and 36, thus the weight will always be uniformly distributed relative to the

rockers

39 and 40 and will be centered on the pivot 42. EX- periment has proved that the governing of the revolutions of the weight is necessary to obtain the best results as the rockers when out at a certain radius will eiiiciently rock the cradle at a certain number of reciprocations per minute, the larger the radius the fewer movements of the cradle. When the governor is adjusted to substantially the same number of revolutions relative to the movement of the cradle the efficiency of the motor is considerably increased. It has also been noted that the cradle will have a tendency to govern the velocity of the weight but however, an additional governing means is necessary to give satisfactory results and in numerous models which have been made the proportioning of the radius of the rockers to the motor when properly adjusted will rock weights in the cradle which are large relative to the weight of the motor and by winding the spring the cradle will rock more than half an hour with substantially the train of gearing illustrated in the accompanying drawings. I do not wish to be limited however, to the specific construction illustrated in the accompanying drawings and herein set forth, but wish to depart from such details as are within the scope of my invention.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States, is:

1. In a cradle rocking device, a motor, and a weight rotatably driven thereby to cause the cradle to rock.

2. In a cradle rocking device, a motor, a weight rotatably driven thereby tocause the cradle to rock, and means for governing the speed of said weight to increase the efliciency of the motor.

3. In a cradle rocking device, a motor, a

weight rotatably driven thereby to cause the cradle to rock, means for governing the speed of said weight to increase the efficiency of the motor, and means for stopping and starting the motor.

4-. In a cradle rocking device, a motor, a Weight rotatably driven thereby to cause the cradle to rock, means for governing the speed of said weight to increase the efiiciency of the motor, a stopping device and means for preventing a sudden jar due to the kinetic energy of the weight.

5. In a rocking device for cradles, a rotatably mounted weight means for revolving said weight, and a cradle supporting said weight, said revolving means and rockers having a radius adapted to rock the cradle at a fixed relation with the revolutions of said weight.

6. In a rocking device for cradles, a rotatably mounted weight means for revolving said weight, a cradle supporting said weight, said revolving means and rockers having a radius adapted to rock the cradle at a fixed relation with the revolutions of said weight, and a stopping and starting mechanism adapted to operate on said weight.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
