UNITED STATES PATENT OFFICE.
JOHN W. O. MCCURDY, OF OHARTIERS, PENNSYLVANIA.
CRADLE.
SPECIFICATION forming part of Letters Patent No. 496,531, dated. May 2, 1893.
Application flled January 31, 1891. Serial No. 379,316. (No model.)
To all whom it may concern.-
Be it known that 1, JOHN W. O. MOOURDY, a citizen of the United States, residing at Chartiers, in the county of Allegheny and State of :Pennsylvania, have invented a new and useful Improvement in Cradles, of which the following is a specification.
The invention relates to improvements in cradles.
The object of the improved construction is to simplify devices of this class, and render the same less expensive and more convenient, and also to reduce the noise or jarof the parts thereof in movable contact with each other.
The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claim hereto appended.
In the drawingsz-Figure 1 is a perspective view of a cradle constructed in accordance with this invention and shown applied to a cradle. Fig. 2 is a vertical longitudinal sectional view. Fig. 3 is a transverse sectional view.
Referring to the accompanying drawings, 1 designates a rectangular base mounted upon rollers 2 and adapted to be readily moved about on said rollers and provided at one end with a spring motor 3, which is connected by a pitman 4 with a cradle 5, and adapted to rock the latter. The pitman 4 has one end connected with a crank 6 of the motor and the other end pivoted to a block 7 secured to the outer face of the adjacent one of the rockers 8, and as the crank rotates with the shaft upon which it is mounted, the pitman is reciprocated and the cradle is rocked.
In order to insure a perfectly noiseless motion and to prevent the cradle becoming displaced from the base the rockers 8 are provided on their curved faces with central longitudinal flanges 9, which extend the entire length of the curved faces of the rockers and are arranged in transverse grooves 10 in the face of the base 1; and straps II are secured to the rockers and the base and arranged on opposite sides of the ribs or flanges 9, and each has one end secured to one end of a rocker, and its other end secured to the opposite side of the base. The straps of each rocker are reversely arranged, and are interposed between the rockers and the base and deaden the sound and insure a perfectly easy and noiseless motion and prevent the cradle becoming displaced. The said flanges 11 are arranged centrally of the rockers and curved to conform to the latter, and are of less Width than the depth of the grooves 10, to reduce the friction and render a noiseless operation, and also adapted, by striking the opposite side walls of said grooves, to prevent the rockers. from becoming displaced from a predetermined normal position, and thereby also prevent the straps from becoming twisted.
It will be seen that the motor is simple and inexpensive in construction and is adapted to rock a cradle and insure a perfectly easy and noiseless motion and is equally applicable to rocking body churns and the like.
The spring motor 3 is arranged in a suitable frame or casing and is adapted to be wound by a key in the ordinary manner.
From the foregoing description the construction, operation, and advantages of the invention will readily be understood.
What I claim is- The combination of an elongated continuous flat base mounted on rollers and having grooves extending transversely across the same, rockers supporting a body and mounted on said base and having curved flanges secured centrally to the under sides thereof and depending therefrom vertically and ex tending throughout the entire length of the rockers, said flanges operating in said grooves and of less width than the depth of the grooves to reduce friction and render a noiseless operation and adapted by striking the opposite side walls of said grooves to prevent the rockers from becoming displaced from a predetermined normal position, and straps engaging the rockers on opposite sides of the flanges thereof, the ends of each of the straps being alternately secured to one end of each of the rockers and the opposite side of the base to prevent the body carried by said rockers from being tipped over at either side, said straps bearing on the base adjacent to the opposite top edges of the grooves thereof, substantially as described.
In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
JOHN WV. 0. MCOURDY.
