' IMPROVEMENT IN CRIBS AND CRADLES.

Specification formirg part of Letters Patent No. 153,647. dated July 28, 1874; application led Jai nary 26, 1874.

To all whom it may concern:

Be it known that I, HENREY H. WIGGERs of Cincinnati, Hamilton county, Ollio, have invented anew and useful Improvement in Cribs and Cradles, of which the following is` a specification:

This invention relates to that class of cradles whose bodies or beds are provided with rockers that play upon horizontal bearings at the opposite ends of a supporting stand or base; and my improvements consist in a novel method of coupling the cradle proper to the aforesaid stand or base, which coupling is arrangedas follows: The under or convex surface of each rocker is provided at its midlength with a downwardlyprojecting pin or shank that is adapted to vibrate Within a suitable slot or excavation formed in the horizontal supporting members at each end of the stand or base. These twopins serve as the pivots or centers of oscillation for the cradle, but it is evident that if said pins were employed alone the cradle would be liable at times to rock too far on either side of the sup porting-base, and thereby to overturn. It is also apparent that in attempting lto lift such an article of furniture the cradle would instant-- ly separate from its supportingstand, as the pins would be drawn out from the slots as soon as the crib was elevated a slight distance. Therefore, to overcome both of these objections to such cradles I employ, in conjunction with said pins and excavations, two doublegrooved plates or blocks and four studs or stops that are adapted to move freely within the grooves, it being understood that the as to be in danger of upsetting the appropriate stud then strikes against the end of one of the grooves, and thus limits the movement of the crib. These studs also come in contact with the ends of the grooves, when the cradle is elevated, and consequently they prevent said cradle being separated from its supportingstand. A pair of removable-pins are provided for the purpose of preventing the cradle rocking at all, when desired, the location of saidv pins, together with the manner of using them, being hereinafter fully described.

Fig. l is a perspective view of a cradle embodying my improvements. Fig. 2 is atransverse section, showing the cradle inclined in an opposite direction to that represented in the preceding illustration. Fig. 3 is an end elevation, showing the cradle locked, so as to prevent being rocked, and Fig. 4 is a longitudinal section through one of the rockers on an enlarged scale.

A represents the body or bed of the cradle, having secured to it two customary rockers, B Bf, that rest upon the horizontal end pieces or sills C C of the supporting-stand or base D. These end pieces or bearings are united together by a stout frame, d, although any suitable kind of stretchers or rods may be substituted for said frame or connecting-board. The rockers are respectively provided at their mid-lengths with downwardly-projecting pins b b that serve as pivots or centers of oscillation for the cradle A, and said pins are adapted to play within suitably-shaped excavations or mortises c c in the supporting-sills C C', or in plates 0. These pins, in conjunction with their appropriate recesses, allow the cradle to rock freely from side to side, while at the same time they prevent said cradle being shifted 1ongitudinally of its supporting-stand.- Securely attached to the exposed or outer sides of the sills C Cl are blocks or plates E E', each of which is provided with two grooves or slots, ce', for the reception of studs or lugs F F and Gr G', that project, respectively, from the rockers B B. These grooves are capacious enough to allow the studs to play freely within them without causing any friction whatever, but at the saine time the length of said grooves is suoli as to arrest the cradle in time to prevent its overturning. This result is accomplished by the proper stud impinging against the end of its groove, as shown in Fig. l. This arrangement also enables the cradle to be lifted'bodily without detachin g it from the stand, as it is evident that all of the studs will thus impinge against the ends of their respec-
