" Application filed June 26,

- Be it known that I, ALFRED llRNlCST Ro- Britain, and resident of the city of Nottingland, have invented new and useful Improvements 1n Peran1bulators, of whlch the This invention relates to'improvements in perambulators winch canbe folded into a small space for convenience in storing and invention being simplification in the constructlon'of a folding per'ambulator, and im-' the parts whereby the erambulators can be without the use of separate fastenings,

'To these frames the sides 1 and 2 are "attached and such sides may be of wood, cane or other material commonly used for this purpose and they may be plain or ornamented in any suitable manner. The frames gand 4 are mounted on springs-'5 one end of each of which is screwed to=the frame while the other end is connected thereto by links 5, leather or other similarly flexilole coupling 5*, and. a short spring 5. In the improved perambulator these. springs 5 constitute the sole connections between the pairs of wheelslocated' at the respective mo'uhted upon an independent axle 8 and these axles are attached to or integral with brackets 8 which are secured to the springs 5 and are shaped each to carry an axle or pivot for the end o f-the stay 9, which is ointed in the middle to allow of the persontil" "t rbeing folded, and the joint is shaped Specification of Letters ."Eatent! to; I p a rigidstay between the opposite Patented A mcv, 1909.

wheels of each pair when the pertunbulator provided with an opening 13 to the ends of which pieces 14 and 15 are hinged, such pieces being designed to fill theiopening 13,

, or be less than such opening, so that the bottom 12 and .the pieces 14 and 15 can be turned to rest in contact with the side 1 when .the,pera 1,1bi1lator is closed, while the piece/s14 and 15 form ends to the well or .recess1-6 when the perambulator is opened. The bottom of this well or recess is formed. by a piece 17 which is hinged to the "frame 4 and is of such a width and length that it fits betweenthe vertical uprights of the frame 3, and between the sides 1 and 2 when the perambulator is opened.

The ends 11 of the perambulator are in halves and the inner eiids of these halves are, hinged together while .the outer edges of the halves are hinged to opposite ends of the frames 3 and 4, the parts bcii'ig so arranged and hinged that the ends fold in ward as shown in Fig. 3. The handle ends Of the frames 3 and 4 may be shaped so that they can be grasped by the hands, but preferaloly they are'fitted with a cross bar 20 as shown in the drawings. This cross bar is provided with flattened ends and the frame 3 is fitted with a metal cap 18 to which one end of the cross bar 20 is pivotally connected by a pin 23. The end of the frame t is also fitted with a metal cap 19 and a pin 21 mounted therein is held forwardv by a spring to connect the cross bar 20 to the frame 4:, the end of the cross bar or handle being shaped so as to entera slot in the cap 19 and isoe rforated to allow the pin 21 to pass throud r-it'when thehross bar is disposed so as to he'between the frames 3 and 4. The frame 3 is also provided with a catch 22 suitably. placed toengage with and hold the cross bar 20 when the cross bar is disconnected lrpm the frame piece t as represented in FigS' L' The perambulator is providedwith cushions 2%, 2-5 and 26, the cushion 26 being attached to a board so that it can be used to cover the Well when the bottom of the perambulator is to be'used as a bed.

When the improved carriage is to be i I opened out for use the sides are pulled away from each other until they are approximately as shown in Fig. 3. The stays 9 are ,then forced into a straight line andthis allows the ends to open also, after which the bottom of the well is lowered into position and forms a strut at the'bottom of the sides.

The bottom of the perambulator is then lowered and securely locks the ends in their open position, and While these are held locked the. perambulator cannot be closed. The handle bar is then fixed in position and forms an eiiic'ient tie between the ends of the side fran'ies, with vertical members in such frames, ends in halves hinged to the sides, a bottom piece hinged to one side, the bottom of the well hinged to the other side, and springs wheels and axles carried from the frames substantially as herein set forth.

In a perambulator, the combination of the side frames, a folding body carried by the side frames, a cross bar arranged to constitntc a detachable handle extending be tween the side frames, a cap to which one end of the handle is pivoted carried by one frame, and a cap provided with a spring catch for the free end of the handle carried by the other frame piece.

at. In a perambulator the combination of frames comprising a folding bottom in,

which is formed a bottom closed well.

6. In a perainbulator the combination of a folding body with a cross handle bar hinged to one side frame, a spring'catch for connecting the other end of the handle bar to the other side frame, and a catch for receiving and holding the handle bar when the perambulator is closed substantially as herein set forth.
