Patented Oct. 24:, 1911.

Application fi1ed December 11, 1906, Serial No. 347,258. Renewed February 27, 1911. Serial No. 611,237.

To all whom it may concern:

Be it known that I, ALBERT E. MoGILL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Folding Perambulators or Gro-Carts, of which the following is a full, clear, and exact specification.

This invention relates to folding or collapsible perambulators or go-carts, and it has for its primary object to provide an improved form of device of this character which will be durable, simple in construction, and compact and light when folded up or collapsed.

Another object of the invention is to provide an improved form of folding go -cart of this character which will be capable of folding or collapsing in a lateral direction.

With a view to the attainment of these ends, and the accomplishment of certain other objects which will hereinafter appear, the invention consists in the construction, combination and arrangement of parts which will now be described with reference to the accompanying drawings, and more particularly pointed out in the claims.

In the said drawings Figure 1 is a side elevation of a perambulator or go-cart, minus the seat, constructed according to this invention. Fig. 2 is a plan view thereof showing the running-gear frame in its folded condition in dotted lines. Fig. 3 is an end elevation of the running-gear frame, the handle being omitted. Fig. 4 is a similar view showing the running-gear frame folded or collapsed. Fig. 5 is a detail perspective view of one of the axles and the axle connecting bars. Fig. 6 is an enlarged detail longitudinal sectional view of one of the crossconnections and lock of the running-gear frame. Fig. 7 is a detail perspective view of one of the handle-brace slides and the running gear-frame bar. Fig. 8 is a detail perspective view of the upper end of one of the handle bars and a part,

of the cross-connection. Fig. 9 is a side elevation of a folding perambulator showing certain modifications of this invention hereinafter described. Fig. 10 is a crosssection thereof on the line 1010, Fig. 9, showing the parts folded up in dotted lines. Fig. 11 is a detail perspective view of a brace hereinafter described. Fig. 12 is a detail perspective view of another brace and a part of one of the side members of the seat frame. Fig. 13 is a detail perspective view of the support on the running-gear frame for the seat frame. And Fig. 1 1 is a detail perspective View of the connection between the running gear-frame and seat frame.

According to this invention the entire vehicle isfolded or collapsed in a lateral direction, or inwardly. The axles, two of which are employed for the four wheels 1, 2, 3, 4., are each composed of a plurality of sections hingedtogether. In this exemplification of the invention, each has three sections 5, 6, 7, connected together by hinges or pivots S, 9, and these hinges are so formed that the sections 5 and 7 at the extremities may be folded upwardly out of line with the section 6, but cannot fold downwardly beyond such line. The wheels are mounted upon end sections 5, 7, which are cylindrical in form so that they may turn thereon as usual, and they are capable of sliding longitudinally on these sections to points inwardly beyond the joints or hinges 8, 9, and so much of the section 6 over which the wheels 1, 2, are required to slide during their collapsing movement, is also cylindrical. For convenience of construction the entire axle from end to end is made cylindrical and of uniform diameter. When the wheels are thus pushed inwardly as shown in Fig. 4;, the end sections 5, 7 of the axle may be turned upwardly as shown in said figure, thus placing the wheels and axles in a compact collapsed form. The ends of the axles are connected together by bars 10, 11, which serve the twofold purpose of spacing the axles and of limiting the outward movement of the wheels. These bars may be connected to the axles in any suitable way, such,

for example, as by slotting their ends and letting the bars thereinto and then passing through the two members a cotter or pin 12. The bars 10, 11, also serve the further useful purpose of causing the front wheel to slide inwardly on .its. axle. along, with the hind wheel, when theabar. on .thatside. is grasped at an intermediate point in its length.

The wheels, 1 to 4 inclusive, may be mounted between the branches of forks 13, 14, 15, 16, of the usual or .anysuitable form, having hubs 17, secured to the side bars 1 8, 19, of .the. running;gear.frame, whose end bars are constituted by a plurality of hinged memberscapable of folding together to accommodate the collapsing movement of the wheels; 3 and {side barss of. the frame. The front cross-bar of. the runningrgear. frame .is composedoftwo sections. 20, 21,: whose outer; extremities are pivoted; at. 22 to they side bars 18, .19,-.of the running gear, frame, while their. inner extremities are pivoted together as shown :at, :23, and. at, a point. substantially midway betweenthe sidebars l8, 19,-in such a manner zthatithe. pivot-point 23 may move directly inward :along the longitudinal :di:- ameter .of the running-gear frame when the side bars .18, 19,'thereof are brought together. Inorder. that. these. sections 20., 21,1 may be: come rigid when in operation, they are.pro.-; videdrwith a .lock, such-as that shown in .Fig. 6, consisting of a springlor yielding plate 24, rigidly secured. tothe section 21,; and having an elastic end :25v provided :with. a lockingv pin 01;.-Sttld 26 adapted .to .enter asuitable socketinthe section 20. when the two sections 20, 21,: are brought into line .as shown inFig. 6. Inorderthatrthe sections 20, 21, may make this folding movement. without. interferencefrom the side bars l8,-19,.each1of the latter is. provided inits innerside with av longitudinal slot for. receiving the=edge of the section-20 or. 21 contiguoustheretd. One of thesev slots is ,illustratedat 27--.in.Fig. 8 in the bar. 19, theone-in the bar.'18 being similar thereto The CI'OSS-rbitl'. l of. the running-gear .frame at therean-endl is similar lIlrCOIlStlllQtlQll .to the crossbar at the forward end,. consistingt of 'twosections 28,-29, and a locking plate 30, corresponding inconstruction and. operation tot-he parts 20, 21, 24 and 25, and their.

. cooperating adjuncts already described, and

adaptedito permit the sections .28,-129,.-to fold inwardly like the sections 20, 21.

A collapsible running-gear frame .as. thus. constructed may, if:desired, be, also-provided'with-a.collapsible' orfolding handle.

The one illustrated in Figs.- 1 and 2 is. constructed eupon theaprinc'ipleof the folding running-gear frame, and preferably consists of two side handle: bars 31, 32,-"whichi are hinged at .their lower ends" by means of hinges 33 to the rear extremities ofthe side bars 18, 19, and at their upper ends are connected together by a cross-connection consisting of folding sections 34, 35, which are pivoted at their outer extremities to the bars 31, 32, and are pivoted together at their inner extremities similarly to the sections 20, 21, in such a manner that the two sections 34, 35, may fold inwardly with the intermediate pivotalpoint thereof following along the medial diametric line of the running-gear frame. When in operative position these sections 34, 35, areheld in alinement with each other rigidly connected by a lock 36, which is similarin construction and operation to the lock shown in Fig. 6 of the drawing, and which latter may be regarded as a section of this lock as well as of the locks for the crossconnectlons of the running-gear frame. The

hinges 33permit .the handle bars 31 and32 to beturneddownwardly in a forward direction, asshown in dotted lines inFig. 1, so as tooverlie, and be substantially coterminous with,zthe running-gear frame, in a compact form.- In .order to render the handle bars rigid; and eflective in their functionof pushingwthe vehicle, they are provided with braces 37, 38, which are pivoted at their upper endsto the handle bars 31, 32, and at their lower-:endsto. slides 39, 40, suitably mounted and sliding upon. the side :bars .18, 19,.of .therunning-gear frame, and having hooks, latches, or other suitable! locking means, .41, see. Fig. v7,. for. holding them 4 against forward movement when the handle is. inrits operative position, pin.on;eachofthe bars 18, 19, for cooperating withthe latch 41 in accomplishing this result:

In the form of the invention shown-Vin- Figs. 9 to, 14 inclusive, the. device is provided with a collapsibleseat and foot-rest. The foot-rest, which is here shown as of a box-likeformation.43 composed of fabric or other suitable flexible material, is supported at its forward side from the cross-connections 20, 21, and at its rear side/from the forward edge of the seat 44, and; the seat, which is here shown asv of abox-like construction, may be formed of any suitable cushion and flexible sides 45 and Ebaclr46, the. sides being suspended from side bars 47, 48, constituting a seat-supporting frame. Thesebars 47, 48, are pivoted at their forward ends to the side bars .18, 19,'of the running-gear frame, as shownat 49, in such away that they may be folded downwardly, orin planes parallel with each other, and substantially at right-angles to the axles, in the :manner shown'in dotted lines in Fig.9, when their rear ends are lifted out of their supports 50 -on-the running-gear frame. These supports consist of hook like members secured'to the side bars 18, 19; withwhich engage-.hook-like extremities 51' of thebars- 47, 48, and'when thebars 47, 48, are in 42 being a lugor.

their lowered positions they are supported and held in place by stops 52 on the inner sides of the bars 18, 19. As the side bars 47, 48, descend, one side of the seat 4A- is elevated to a perpendicular, or substantially perpendicular, plane, so as to cause it to lie in a compact form between the side bars 18, 19, as shown in dotted lines in Fig. 10, the foot-rest being similarly arranged. In this form of the invention, the braces for connecting the handle bars 81, 82, with the runninggear frame, instead of connecting at their lower ends to slides like 39, are pivoted to the side bars 47, 48. These braces are shown at 53, and one of them is illustrated in detail in Fig. 11. Their rear ends are pivotally connected with the bars 31, 32, and their forward ends have notches or hooks 54, which are adapted to engage with a cross-brace 55, serving to connect the rear ends of the side bars 47, 4:8, together, the bars 47, 48, having suitable eyes 56 for reeeiving the down-turned extremities of the brace 55, and the braces 53, if desired, may also be connected together by cross-braces 57 having down-turned extremities 58, engaging in loops or eyes 59 struck out from the inner sides of the braces 53.
