SPBCIPICATION formixig part 01' Letters Patent N0. 335,203, dated February 2, 1886.

Appliontion filed October E20, 1885. Serial N0.180413. (N0 model.)

T0 all whom it 7nay concern:

Be it known that I, CHARLES P. KENNA, u oitizen 0f the United States, residing in Chicago, in the eounty of Cool; end Stute 0f 111inois, have invented a new und useful Improvement in Folding Oradles, of whieh the following is a speeification.

The objeet of myinvention is to provide a folding oradle of a simple, cheap, and dumble eonstruotion which 1nay be readily folded into a oo1npact shape I"or storage 01? shipment or unfolded and sei: up for use, and without the necessity of rexnoving sorews or fastenings er taking the structure to pieees; end to this end my invention consists in a oradlebody eomposed of bent or curved longitudinal ribs pivoted toget-her at eaoh end and adapted to shut or fold inside eaoh other.

Anothr feature of my invention consists, in oonjunction with the pivoted longitudinal ribs, of a flexible strap 01 oonneotion between them to sustain the separate ribs in position end permit them to be folded 01 shut together.

Another feature consists in arranging the pivoted longitudinal ribs in two or more sets or series, each set or series being separately pivoted to a oommon end or frzune piece ab eaeh end of the oradle.

lt also consists in providing the end 01 frame pieees to whieh the ribs are pivoted with so parately-pivoted longitudinal top rails 01 fra1nebars, adapted 130 fold together upward end to turn down only to a horizontal position er op posite eaeh other when the oradle is extended for use, and thus form a rigid support for the pivoted ribs flexibly oonneeted therewith.

lt also oonsists in a frame or Support forthe oradleloody, composed of two or more (preferably three) pieces pivoted or jointed together, the pivots or joints being loouted inside the line of support at euch end of the cradlebody so that the weight of the oradle-body will serve to hold the jointed frame rigid.

'Ihe invention also consists in providing one of the joints of the frarne with soekets 01 reeesses to reeeive the axles of the wheels when the frzune is opened 01 extended. The mere aet of opening the frame thus fastens the wheels in plaee, end the moment the frame is elosed the wheels are released therefrom.

The invention 'further oonsists in making the supporting-frame of two sides 01 parts pivoted together ab each end als the top, so that they will fold 1'11t0 more eompaot shape; end the invention also consists in the novel devices and novel combinations of devioes or parts herein shown and described, und more partioularly pointed out in the claims.

In the accompztnying drawingswhich form a part of this speeification, und in whieh similar letters of referenoe indicate like parts, Figure 1 is a side elevation of a cradle embodying my invention. Fig. 2 is an end view of the same. Fig. 3 is a view showing the oradle folded. Fig. 4 is a detail view of the frame-joint whieh serves to seeure the axle, end Fig. 5 is a side view of the frzune as folded.

In said drawings the folding fmme or support upon which the oradlebody is mounted is shown as being eonnposed of two bottom mils or bars, A, each having an upright folding part, B B, jointed or hinged thereto ab each end. The upright parts B B are pivoted together ab their upper ends, so that the two sides or parts of the frzune A B B und A B B may close or fold together. A braee or streteher, b, preferaloly having a joint, b, at its rniddleand pivoted ab eaoh end to the uprights B B, so that it Will fold, serves to hold the two sides o1 parts of the frame rigid when the Same are extended or spread apart.

The joints 01 hinges a a at the ends of the bare A should be located inside the line of Support at oaoh end of the oradle-body, so that the weight of the cradle will serve to hold the uprights B B and B B extended, as indieated in Fig. ltahat is to sny, the bottom rails, A should be shorter than the cradle-body, and by this means also the frame, when folded, is adapted to be plaeed inside the bent er ourved longitudinal ribs O, whieh fonn the body ot' the cradle, .ns indioated in Fig.

The adjoining 01 abuttingends ofthe folding frame-pieces A B und A B are provided, one or both, with recesses o1 groovesa", to reoeive the axle E of the wheels E, and thus afford a means of readily attaohing anal securing the wheels in place when the eradle is extended for use. This Socket a, for attaching the wheels,may be formed in the hinge-plates or 011 separate braokets nttaehed to the folding arms A B B, if desired.

Ihe eradle-body is composed of longitudinal folding ribs er slats O, pivoted 01 hinged together at er near their ends.

D D are the end pieees 0r eastings, t0 whieh the rilos C are pivoted at two projeetions or arms, d, thereon by the pins d, one on eaeh side of the center or median line of the eradlebody. These armes d are 01 should be provided Witli slots, in whieh the ends of the ribs C fit.

T0 the end pieees, D, are also pivoted the folding top or fra1ne rilos, O, which have square ends or other stops, c, to hold them rigid when turned at right angles to the suspension-pieees D, and thus afford rneans of supporting the ribs O. The 'ribs G are eonneet-ed to eaeh other-that is to say. all those whieh are pivoted ab the san1e point to the end pieces, D, and 130 the upper or frame rib, O, loy means of flexible straps C. The frame-ribs O are pivoted to slotted ar1ns 01 projections (Z 011 the end pieces, D, which are 01 should be Suffieiently shorter than the arme or projeetions d to permit the ribs C to reverse 01' i'0ld together upward from the position shown in Figs. 1 and 2 to that shown in Fig. 3 without obstruetion from said arms d. The frarne-rilos C may, hoivever, loe pivoted to the end pieees, D, in other relative positions than that shown without departing from rny invention.

The end pieees, D, are provided with rings or eyes d, loy Which the eradle-body is suspended on the hooks .d* on the supportingframe, so that it can freely swin g and be readily attaehed orremoved.

F is a handle attaehed to the folding frame at one endthe end to which the wheels are not applied.

Bach sueeessive folding rib C is slightly larger than its preceding or inner one, so that the ribs will shut or fold inside each other.

The bottom slats, C, of each set or side may be eonneeted together by hooks 0 or other suitable fastenings.

The rilos O, a s well as the frame-ribs O, are bent 01 eurved in shapeso that when extended they will form a eradleshaped body, as shown in Figs. 1 and 2.

I hereloy disclaim as forming no part of my invention the folding eradle shown and deseribed in Letters Patent N0. 237 820, to O. O. Olark, dated February 15, 1881.

In my invention the eradle-loody consists oi' one or more (preferably two) sets or series of bent longitudinal ribs pivoted together at their ends, and adapted to shut er fold together, one inside of another, and to for1n when extended a rigid cradleshaped frame or body, and each Set orseries of longitudinal bent ribs eonsists of three o1 more (preferably five) ribs pivoted together.
