tion' of the wining-gear frame; D, foldab-le brace-bars connecting the upper portion of the .handlewith the front portion of the T 0 all whom it may concern: Be it known that I, ARTHUR J. ADAMS, a citimn of the United States, residing at 1263 l West Congress street, Chicago, in the county of Cook and State of Illino's, have invented a newand useful Improvement in Folding angular structure, said brace-bars serving Carriages, of which the following is a specialso as a means from which the seat may be fication. suspended; E, a seat having its fr }por- My invention relates particularly to fold i-ng baby carriages, doll carriages, goc'arts, and the like; and my primary object is to provide improved means for looking the wheel-supports in an upright position.

The present application constitutes a division of application N 0. 431,312, filed May 7, 1908, and the improved means here shown for lockin the wheels in an upright position constitutes an improvement upon the mechanism shown in my patent No. 857,971, "granted June 25, 1907.

The invention is illustrated in the preferred embodiment in the accompanying drawings, in which- Figure 1 represents'a' side elevational view of a folding baby carriage equipped, in accordahce with my invention, with improved means for locking the wheel-supports in an upright position; Fig. 2, a broken perspective view showing a fragment of my improved folding linkmechanism and the manner of connecting the same with the wheel-supports or wheel forks; Fig. 3, a plan section taken as indicated at line of tion suspended by links E fronrthe ears 1) and having connected with its lateral edges side flaps E which are permanently secured to the bars D; F; a back having its lower portion flexibly connected to the rear por tion of the seat, the upper portion of said back being shown joined, by connections f, with the bars D; and G, a foot-rest connected with the lower-portions of the bars D, said foot-rest forming no portion of the present invention.

The running-gear frame A may be of any suitable construction. Preferably, it comprises horizontally disposed longitudinally extending side members a connected by cross members a, in a well known manner. The pair of wheels B at each side of the cart is adapted to fold together beneath the running-gear frame in a well understood manner. The two wheel-supports at each side of the frame are'joined in a pair by a longitudinally extending bar 1, connecting the lower ends of said wheel-supports, so that each side pair of wheels will swing as a unit. The lower ends of the wheel-supports have connected therewith the out-turned spindles 2 upon which the wheels are journaled.

The link mechanism B comprises, in the preferred form, a folding front cross-bar 3; a folding rear cross-bar et; and a longitudinally connecting link 5. Each folding crossbar comprises a pair of links 6 and 7, which are joined together near the median longitudinal plane of the running-gear frame by a vertical pivot 8; short, angle-form links 9 joined to the out-er extremities of the links 6 and 7, by vertical pivots, l0; and angleform clips 11 having forwardly directed flanges 12 rigidly joined by bolts 13 to the wheel-supports B and having inwardly turned flanges 14: connected by horizontal, longitudinally disposed pivots 15 with the depending arms of the angle-form links 9. The clips 11 are connected with the wheelbrackets, or wheel-supports, B a short distance above the lower endsof the brackets.

0 Fig. 1; Fig. 4:, a broken front elevational View taken as indicated at line 4 of Fig. 3, and 'Fig.j5, a front view of the running-gear frame, showing the Wheels in folded condition.

The general construction of the folding baby carriage in connection with which my "present improvements are illustrated Wlll be stated briefly, followed by a more practical description of the matters to whichthe pres ent application iiertains.

In the construction illustrated, A represents a running-gear frame; B, pairs of with the running-gear frame by pivots B and adapted to fold beneath the runningear frame in a well known manner; B

in the brackets 13 crosswise in a manner to presently described in detail; C, a hani connected y n s 6 w he ear P THE FULTON MANUFACTURING running-gear frame, and forming with the runninggcar frame and the handle a trl- The links 6 and 7 preferably comprise fiat bars which are disposed in horizontal plane.

when the wheel-supports are in the upright position; and the short links 9 preferably comprise short bars bent into angular. form. The link 5 preferably comprises a flat bar whose ends are pivotally connected with the pivots 8, so that the link 5 occupies a median longitudinal plane, as will be clearly understood from Fig. 3. For the purpose of sc curing the links in the position shown in Fig. 3 and locking the wheel-supports in an upright position, the links 6 and 7 composing the front foldable cross-member 3 are equipped with a locking device 16 of the construction shown in said Patent No. 857,971. It is unnecessary to describe the fastening means 16 in detail. It is sufficient to say that it comprises a spring-held slide 17 mounted on the bar 6 and adapted to engage the extension 18, .of the link 7 which projects past'the pivot 8, as will be clearly" understood from Fig. 4. i

The horizontal arms of the angle-form links 9 are connected with the bars 6 and 7 by means of the pivots 10 Figs. 2 and 4) a short distance from the outer ends of saidbars. 'Ihue, the bars 6 and 7 are provided with extensions 19 adapted to-engage the mner surfaces of the Wheel-forks, or wheelbrackets, Bi, when the mechanism is in the extended position shown'in Figs. 2, 3 and 1.

Thus is provided. a thoroughly efiective.

means for bracing the wheel-supports when the latter-are in the'vertical position and the mechanism B is in the extended, bracing position shown in Flgs. 3 and 4. WVhen it is desired to fold the wheels laterally inwardly beneath-the running-gear frame, the slide 17 maybe wlthdrawn against the pressure'of its spring, and the link-mechanism B may then be folded as the pairs of Wheels are swung inwardly to the folded position.

I The foregoing detailed description has been, given for clearness of understanding only, and no undue limitation is to be understood therefrom.

WVhat I regard as new, and desire to secure by Letters Patent, is

1. In. a folding carriage, the combination waste links pivotally connected with the end per-- tions of said cross-members and with sald' wheel-supports, and extensions carried. by said cross-members adapted to engage the innersurfaces of the Wheel-supports when. the mechanism is extended, thereby to brace the wheel-supports.

3. In a folding carriage, the combination of a running-gear frame, a pair of Wheelsupports pivotally connected with each side thereof, a pair of fol'dable cross-members, links joined by vertical pivots to said cross-' members, clips carried by said wheel-supports and joined by horizontal pivots to said links, extensions carried by said foldable cross-members adapted to brace said wheel supports, and the cross-members.

at. In a folding carriage, the combination of a running-gear frame, a pair ofwheelmeans for giving rigidity to supports pivotally connected with each side I thereof, a pair of foldable cross-members, angle-form links having horizontal arms joined by vertical pivots to said cross-members, angle-form cli s carried by said Wheelsupports, horizonta pivots connecting the. inturned arms of said clips with the vertical arms of said links, and extensions carried by.

said foldable cross-members and adapted to brace said Wheel-supports.
