My invention relates more particularly to that class of perambulators or go-carts 1n- \Vith these ends in View my invention con-' sists in certain features of novelty in the construction, combination, and arrangement of parts by which the said objects and certain other objects hereinafter appearing are attained, all as fully described with reference to the accompanying drawings, and more particularly pointed out in the claims.

In the said drawings, Figure 1 is a plan View of my improved perambulator or gocart. Fig. 2 is a side elevation thereof. Fig. 3 is an enlarged detail sectional view taken on the line 3 3, Fig. 1. Fig. 4 is a front elevation of the complete device. Fig. 5 is a detail longitudinal sectional view taken on the line 5 5, Fig. 1. Fig. 6 is a side elevation of the device folded up or nearly folded up. Fig. 7 is an enlarged plan view of a portion of one of the side members and the joint of the handle; and Fig. 8 is an enlarged crosssection on the line 8 8, Fig. 2.

The wheels 1, preferably four in number, are journaled in any suitable supports, brackets, or bracessuch, for example, as forks 2. The manner of attaching these forks to the frame of the vehicle is the same for each, and therefore the description of one will suffice for all. The fork is formed on or secured to a collar 3, and these collars are sleeved on side bars or members 4, which constitute the sides of the frame or part which might be called the running-gear frame, so that the collars will be capable of a limited degree of rotary motion, and consequently when desired the forks may be folded under the vehicle toward each other in the manner illustrated in Fig. 6, thus lapping the wheels on one side over the wheels on the other side. In order, however, that the forks may not rotate too far when being turned downwardly to their operative position, as shown in Fig. 4, the collars are provided with shoulders 5, which when the forks are at an upright position ready for use, as shown in Fig. 4, engage with shoulders 6, formed on four fittings 7, secured to the ends of the side members 4,

and also constituting means whereby cross members 8 9 of the running-gear are attached to the side members 4 and by which a rectangular running-gear frame is constituted with one of the wheel-forks rotatively mounted at each corner thereof.

In order that the front and rear forks, brackets, or braces for the wheels may be connected together in pairs, so that the rotary movement of one on each side will be imparted to the other on the same side, they are rigidly secured to side bars 4, journaled on the side members or bars 4, the bars 4 4 being preferably composed of two telescoped tubes, as clearly shown in Figs. 5 and 8.

The collars 3 are rigidly secured to the outer tube 4 in any suitable way, as by brazing or otherwise, and this tube turns freely upon the inner tube 4 between the two end fittings 7 as far as the shoulders 5 6 will permit. Then the wheels arrive at an upright position ready for'use, as shown in Fig. 4, the outer tube 4 may be held against rotation on the inner tube by any suitable pin or lock, preferably passing through the tubes. As a means of accomplishing this, I prefer to employ a brace 10, which is in the form of a rod with its lower end passing transversely through the tubes 4 4 and havinga bend or shoulder 11, which limits its downward movement, while the upper end of this brace is bent at an angle, as shown at 12, and engages in the side of a pivoted seat-support composed, preferably, of a U- shaped member 13, one of the braces 10 being of course employed on each side, and thus serving the twofold purpose of locking the wheelforks against rotary motion and supporting the seat-support 18 at the desired elevation above the running-gear members 4 8 9.

The U-shaped seat-support 13 is preferably composed of a piece of bent tubing for the sake of strength and lightness, and the lower ends of its branches are pivoted in any suitable way to the running-gear, preferably by means of collars 14, journaled on the cross member 9 between the fittings 7 at one end of the running-gear, so as to be capable of being folded up between the side members 1 of the running-gear and substantially in a plane 1 therewith. The scat-support 13 maybe thus lowered until its upper end rests upon the cross member 8, when the braces 10 are removed, their upper angular ends 12being fastened in suitable sockets in sides of the seat-support, and the removal of these braces also permits the wheel-forks to be folded under the running-gear frame, as before described. In order that the lower edge of one wheel may fold up a little higher than the other wheel, the cross members 8 9 are bent upwardly at their mid-lengths, as shown at 8 and 9, respectively, without, however, interfering with the full downward movement of the seat-supporting member 13, whose sides embrace the upwardly-bent portion 8 of the crossmember 8.

15 is the seat, which while in use may be supported in substantially a horizontal position bymeans of a pivoted cross-bar 16, whose ends are journaled in the sides of the seat-support 13 and which cross-bar pivotally supports the forward edge of the seat, while the rear edge is supported by any suitable flexible connection such, for example, as one or more cords 17, having their lower ends attached to the seat, while their upper ends are passed through perforations 18 in the cross member of the seat-support and then knotted to prevent them from pulling through, as shown at 19.

20 is a foot-rest whose forward edge is secured by pin 21 to the cross member 9, while its rear edge is supported by a flexible connection or cord 22, preferably a single cord, which passes through the cross-bar 16, which is hollow for that purpose.

23 is a handle by means of which the device may be pushed or pulled and which handle preferably consists of a U-shapcd bar having its branches pivotally secured to the runninggear, so as to be capable of folding down over the latter, as shown in Fig. 6. This figure of the drawings, however, does not show the handle 23 folded down as far as possible, excepting in dotted lines, it being left a little elevated for the purpose of illustrating the parts beyond, and when so folded down its side members embrace the upwardly-bent section 9 of the cross member Q that is to say, said upwardly-bent section when the handle is folded down stands in a plane substantially the same as the plane of the handle. In order that the handle may be thus pivoted to the runninggear and folded over it, the pivotal points between the handle and the running-gear are slightly elevated relatively to the runninggear, as better illustrated in Fig. 5, in which it appears that the rear ends of the inner tubes 4 are provided with plugs 24:, whose outer ends are turned upwardly and formed with hinge members 25, which match hinge members 26, formed on the lower ends of the handle and which are pivoted thereto by setscrews 27. The contiguous faces of the hinge members 26 are provided with teeth or serrations 28, so that the handle may be locked in the desired position.

In Fig. 2 of the drawings the seat-support 13 and seat 15 are shown at an inclination suitable fora sitting or slightly-reclining posture; but it will nevertheless be understood that the inclination of the seat-support 13 may be varied at will by changing the position of the braces 10, for the accomplishment of which the sides of the seat-support 13 are provided with additional holes or sockets 29 for the reception of the upper angular ends 12 of the braces and the tubes ist with additional perforations or sockets 30 for the reception of the lower ends of said braces.
