In the preferred consti'iicl tion the two cam loops at each sideare yoked together. That is to say, a bar 1G extends between and is at its end rigidly connected to each of the txifo yokes, as shown clearly in Fig. 8 the end'portions of this bar being,- inset and properly shaped to form the

outer cam portions

16 and 16 of the respective cam loops, and the inner members of said loops being formed by shorter cam bars 17 and 1T suitably attached rigidly to the main bar LG. Each cam loop, as viewed in plan, comprises an outer straightlongit-udinal portion 1S, an inner straight longitudinal' portion 19 and an intermediate curved portion 20. Moreover, as viewed inside -elevation, the cam bars 17 and 17 stand in "a plane above the cam bar 16 at a distance from the latter approximately equal to the width of the bails`12' and 13. Normally the legs of the hails occupy the straight outer portions 18 ot the. respective cani loops, and said. portions loeirig at right angles to the' planes of pivotal movement of the wheel yokes they other they first encounter the curved poijl' tions ot the inner side cani loops. thus swinging the `vokes inwardly, 'and as theY l hails pass out of the curved portions the the end of its oscillation.

inward movement ot theyokes and incident rolling movement of the cam loops causes the straight horizontal bottom portion ot the bail to encounter the inner members of the cam loops and vcontinue the folding movement ot the lvokes, lifting the latter into their fully closed position as the bail reaches Th'e unfoldingi movement wil.l."of course. he exactly thereto impart a somewhat earlier o1 quicker folding' movement ot the wheels at. that side and permit the opposite wheels to fold over the latter.l ln this connection will be seen thatsince the two wheels at each side are `yoked together by the rigid bar 1G. a single cam loop and operating bail might he made to fold both wheels, although obviously such a construction wouldl require somewhat heavier stock for the cani mechanism and `would objectionably add to the weightv of t-lie vehicle, or. it not. made heavier, leave it less rigid. Q 1

As an' extremely simple and etl'ect ive A means of operating the canpbails a leverage mechanism is-provided, comprising a pair l ot' levers, preferably' united together at their lower ends to form a lever bail. 21, to the i upper ends of which are connected the side arms 22 of the body. The lever bail is pivotally connected, as indicated at 23, to each of the side bars and operatively connected with the respective cani hails 12 and. 1?), at each side by links Q4 and 25 connected to the lever bail at points respectively below and above its pivotal axis. y By this simple expedient oscillation of the lever bail in one direction draws the two cam hails toward each other, and in the other direction thrusts them apart.

Thelever bail is operated from the handle frame, through the arms 22. The handle frame comprises a pair of upright bars 2G connectedr at their upper ends b v a cross bai- 27 and each lconnected to the corresponding side bar 1 by what may be aptly termed a rule joiiit'QS. That is to say, the side bars and handle bars are respectively provided with joint 'cli'ps, as 29 and 30, having overlapping pivot ears united as indicated at 3l, the clips being;` so formed as to provide abutting shoulders which limit the unfolding movement of the handle frame. Each handle bar is pioyided intermediate its length'with a clip,as 32, to which the corresponding en|d ot' the arm 22 is pivotally fconnected,'as shown clearly iii the drawings. ln order to lock the handle Jf'ranie in its noi'inal or operative position, a cross-rod Sil is'arranged to extend through the heel portions of the two clips 30 of the handle bars, `and with this cross-rod is arranged to copei'ate a locking bail 34y Fig. 2) which has the ends oitY its two arins p ivoted to the f respective side bars, las indicated at 'and is provided in the rear edges ot said arms with hook-shaped notches 36, which, when the handle tra-me is fully open, engage thev cross-rod 3? andthus lock theV two members of each rule joint rigid with each other. rlhishail may be operated bygrasping it troni the rear, and is a convenient means ot operatingV a pair of locking-levers 37 connected with the bail by means oli corresponding links BS; each lever 3T being` pivloted at its lower end to one of the side bars.

1 and being normally held locked lin a hookclip 29 secured to the corresponding' folding;

side plates fl() of the body, as hereinafter slightly spaced away liro'in the arm, as l shown clearly in Fig. To impart an in wardly folding nieveii'n-nt. to the side bodies.

Loan-elan 3 'each 'is provided iyith allink 43, which al onev end ia .pivoially connected with ille lower part of the side body alloull 1nidlength of the latter., desirably to ille lloolr 5 clip 39, and at its opposite end pivolally connected with The corresponding' arm of the lever bail.' as indicated at 44', ily' .means of an eye formed on the rod and passing' through a suitable aperture in lle lever bail. l 'llle operating link 43, when theside body is in normal position,` siands Slightly for# wardlj.Y divergenl'. from llie side body. so iliat as ille lever llail is oseillaled forwardly, illus carrying "with it ille side body bodily,

'lllie infolding movement is resisted by a spring `finlger 45 rigidly' mounted upon the lever bail. and` at iis' free depending` and engaging the inner aide of the `link i3. v

straps 68 In order to hold the canopy extended, front conining are provided which extend from the front upper edge ofthe canopy downwardly to and are attached to the front ends of' the side bars, while similar' securing straps 69 connect the rear bow with the respective arms provided at the upper end of the front bow Gl at each side, and similar buttons at the upper ends of each of the two intermediate bows (52 and G3. By detaching the straps (3S and applying them to the buttons on the bow G2 or 63, the front portion of the canopy may be folded back so as to partially collapse the same. -It will be noted that the length of the bows is such that they reach what stronger Aover the upper end of the back member 46, and thus do not interfere with the latter in folding. It will also be understood'that the width of the canopy is such that the several bows fold between the lateral edges ofthe back member 46 and the side handle bars 2G and arms 2Q.

In Fig. 9 is shown a view similar to Fig. 7, wherein a modified form of the locking` bail mechanism' is notching the upright legs of the locking bail a sheet metal clip 7l is secured t'o the inner face of each of the joint members 30, which clip is provided with a lug or ear 72 formed integrally with one edge of the clip and foldedfbaclr so as to overlie the inner face of the latter andstand at a distance therefrom equalapproximately to the thickness of the bail arm. This clip is so located that when the bail arm rests between the ear and the face of the clip the bailbar 3.4:- engages the upper end of the ear and so locks the member 30 rigid with the member 29 ofthe joint. The remainder of the i'nechanisin is precisely the same as that -previously de'- seribed. This construction dispenses with the locking bar 33 and avoids the necessity of notching the locking bail arms to engage tliisbar and at the same time aords asemeconstruction and one less liable to become bent so as to render it inoperative. i

From the foregoing description it will be understood that we accomplish the several stated objects of the invention and produce a cart which is at once simple, economical of i manufactureand extremely convenient especially in the matter of folding and unfolding. Iturthermore the cart is so constructed as to insure greatestsafety and` comfort to the occupant. That is to say.the substantially inflexible sides prevent" danger of the child falling out, and the various adjustments provided for enable the vehicle to be made most comfortable for the child whether .sitting upright or resting inl reclining position. It will be further understood that while we have shown a preferred embodi- Desirably a button TO is',

detailed. Instead of .bar at points ment of the invention, nevertheless the details of construction and arrangement may be modified without departing from the spirit of the invention.
