invention relates to perainbulators 14}- i 'known as go-carts and more specifically 'to'that class thereof The object of -my invention is to provide a erambulator of the. character mentioned w ich' will be of a foldable nature adapting the seine to be readily' collapsed so as' to 'occu'p a comparatively sniall compass thereby e ecting convenience tion or storagejthereofg 'A further object is the provision of a gocart which may be folded by a single move-' in the transporta ment, or, by the actuation of a 'sin le lever hence makingit possible to fold tie same 1nt o ppllapse POSltlQIl the shortest time poss1 e.-,

' A still further objccti is the provision of a go-cart which w1ll be highly efficient, strong, durable" and comparatively simple of constructionhence'fof low cost to manufac ture.

Other objects will appear hereinafter. lVith these objects intview my invention consists in a'perambulator characterized as above mentioned and certain details of construction and arrangement of'parts all as will be hereinafter fully described and more part cularly pointed out in the appended claims. 7

yond a vertical position. J ournaled in the lowerextremities of said forks are wheels .9 of any suitableconstruction. Connecting- .the wheel forks 6 upon like sides of the perambulator or those mounted-upon the same bar 4, are longitudinallyextending bars 10 the same being positioned upon said forks at different relative elevations for a purpose which will be hereinafter described. Having their outer ektreniities 11 pivoted lmtween' pairs of inwardly projecting lugs 11' secured to the bars 10 at the rearward end portions thereof, in transversely alining positions thereon, are rods 12 and 13- overlapping at their inner 'end portions. The member 12 is provided upon its contacting surface with a projecting pin 14 engaging an elongate narrow slot 15 proand lower edges of its inner extremit with being spaced apart, as clearly shown in Fig. 6, tosuch an extent as to permit of slight rocking n'xovement. of saidmembers 12 and 13, for a purpose which will be obvious as the description proceeds. Provided in the inner extremity of said slot in the'upp'er surface thereof is a notch 17 of a shapeadapt- Saidl notch is so positioned in. the member .13, a d- .the pinl l is so positioned upon the member 12, that'whe'n saidpin is in engage- I'rientwith said notch,v the forks 6 Wlll b dsp'osed in avertical position, said engageing in engagement with the underside. of

ment between said pin and notch being such as to serve as a lockingmeans tomainta ln said forks in vertically disposed positions. With the relative arrangement of said pin; and notch as stated and 'shown, the nterlockin thereof will evidently. be occasioned, upon t e same-being brought to registermg osition, through the gravity of the *mem-" rs 12 and 13; the registerlng thereof be ng effected through the forks an Wheels Wll-lChL by their own gravity are normally disposed in a vertical. plane I Pivoted as at f18 to the ,inner :side -of therunning-gear framesidebars 4, the same being positioned thereon sothat theqbarsilt). thereof shall be in transversely aliningqi'psition relative to the bars 4, g isa substantla yi U-shaped memberf20. 21 =ingpivotal' connection at their forward extremities with the-upper entre nitiesf'o'f said bars 19;"and at: their rearward: ex reinitieswith the handle bars 2, establish operative connection between the latter andisaid handlebars; In

swinging connection jvith, the preferably ill-- wardly ofi'set lower "extremities ofzthebars 19. are rearwardly' extending,;:substantially horizontally disposed rods, 22 j oined at their rearward extremities by a hand grip form ing cross bar 23,, Saidrods 22aresupported at their rarward ends f on a trans versely extending bar-2d the o set end-po tions 25 of which. are rigidly securedin. cars 26 depending from the rearmost' of the 001 a lars 8, the elevational; position of said bar being such as to s'osupportgtherods 22 that the upper edges thereof are, disposed in.- close proximity with the lower-edges of the rods 12 and 13, as clearly shown m Fig. =4.

. Provided in each of said rods 22 is a notch 27 which, when they handle; bars are-in; up-

4 right or operative position, engage the ujiper edge of said bar 24, as clea ly shown in *ig. 4, to maintainthe handle such position,

' this being the only means provided ,toeffeot such purpose. v

l Vith the construction thus fardescribed,

assuming the perambulat'or to be in unfolded or open operative position,--it will be seen, that upon desiring jto'fold thesame together,

all that is necessary is'to grasp' thezbar- 23 of the rods 22 andjby a slight rearward and upward movement or drawing thereof such collapsion will be-effected; it being clear that by the rearward drawing ofsaid rodsfthe handle, the member 20, and rods 21 willbefolded together above the running-gear, frame, and that, upon theupward movement of said rods, the inner ends of; the rods12 and 13 Wlll be elevated causing,-first thedisengagement ofthe pin 14 from thenotchli,

and second upon further 'forcin said rods 12 and 13 upwardly, the collaps on or slid-' lng together thereof and hence ,the inward rocking of the forks 6 and wheels carried 65 thereby, to a position below the runningfolding,

"self to th gear frame. -By positioning the cross bars 1,0;at dilferentelevations upon the forks 6, a'sbeforestated,'the contacting points of the f9$1s;;22fwiththe members 12 and 13 connected thereto, ,will be disposed in different horizontal, planes, hence upon the elevation or upward rocking of the .rods 22, oneof saidmembers 12"or'13 will be engaged thereby 'beforej'the other, hence the two sets of ferksmd wheels, namely. those situated upon opposite 'of the running-gear frame, in 1operatim connection therewith,
