My invention comprises certain improved constructions and devices in baby-carriages or go-carts relating, among other things, to the general construction of such devices and to arrangements whereby the parts are collapsible, so as toform when folded a relatively com act parcel which may be easily transported The .construction of the de vice also provides for adjusting the supporting partssuch as the seat, back, and footrest-at. various angles, so that the child may sit upri ht or recline in any position desired.

Anot er object of the vide a very simple construction.

As will appear by the following description, the supportmg-framework may be made' to consist entirely of relatively thin strips of metal so arranged and coordinated as to brace each other when the device is in use in its various positions and to be folded up into a convenient shape when not in use. 7

I will first describe the parts as they are related when the device is in readiness for usethat is, as they are shown in the full outline in the figuresand will later refer to the va rious positions which these parts may take, certain of which are shown by the dotted lines in Fig. 1. The main framework of the go-cart consists generally of two obliquelyarranged frames pivoted to each other at approximately their central points, one of them carrylng the forward-wheel axle and giving invention is to pro- I (designated general The first-mentioned shown at A a The seat-back (designated generallyby the letter B) I form, preferably, of a continuous strip of metal B, bent into the form of a three-sided rectangle and having on its rear edges the pairs of notches B B The framework thus formed is filled in any desired manner so as to form a back for the seatas, for example, by the padded board B which maybe secured into the framework by the screws B B. offset parts A A of the strips A A in any desired m'anneras, for example, by the rivets B B In making pivotal connections between the various parts of my machine I prefer to use rivets, as shown, although, of course, the parts might be secured together in any other suitable manner. The upper end of the seat-back B is held in its upright position by means of a clipB, slotted at B B for the set-screws B B and comprising a hook B extendin over the cross-rod A It will be understood that the back is a trifle narrower than the frame formed by the strips A A, so that when it is turned back to its reclining positions it will easily clear such strips. In order that the back should be supported in various positions other than its upright position, I rovide a back-support y by the letter C) comprising strips of metal C C, pivoted to the strips A A at C C and connected at then lower ends by the cross-rod C 'thus forming a rectangular framework lying inside the strips A A whenthe back is in its upright position. v g y The back may be disengaged from the cross-rod A by loosening the set-screws and pushing up the clip B and it may then be swung back through the supportingframe formed by the strips A A, the framework formed by the side stri s O C being pulled out sufficiently to hold t e back at the proper angle. The notches B B will assist in kee ing the back 'in the desired position. T e back and its support in a. reclining position are shown by the dotted lines in Fig. 2, the position of these parts being designated, respectively, by the letters B C e device is preferably provided with arms, one at each side, composed of strips of -The back is pivoted to the f metal D D, pivoted ito the parts A A at D D and arm-rests D D secured to the strirED D by the screws D D".' On the strips D are the lugs D D, and pivoted: to these lugs are the links D D which connect the arms with the other part of the main supportingframe of the device. This framework consists of twostrips of metal E E, pivoted to the strip A A at E E 'and to the links D D? at E E rear-wheel axle. I

, The seat may be made in any desired form. I have here shown two anIgle-iron strips F F, supporting the seat part which ma be a padded board and which is secured t ereto ythescrews F F". The seat at thebackhas a pivotal connection with the framework by the same rivets E E which serve to secure together the I two sections of the frame. Links G G connect the arm-stripsD with the seat an le-irons F F, the latter joint being made I y means ofa rod G passing through forward extensions of 1IOI1S.

rest which I will designate generally by the letter H, the position of' which is preferably changed when the back is in its in med position. This foot-rest comprises two strips H H", pivoted on the rod G, curved at their u er ends to the extent of the .Width Of t e inks G G and having the ofisets H H, forming shoulders to abut against the links G G to limit the inward movement of the lower end of the foot-rest. At the lower end of these supporting-strips is the footboard H having brackets H H, pivoted at H H to the strips H H. The strips H H are preferably of somewhat lighter material than the rest of the framework and are elastic enou h, so that when the'foot-rest is movedto its orizontal position the offsets may-be pushed ast and under the seat. This positlon of t'e footrest is shown by the dotted lines designated enerally by the letter. H ootboard need not, of course,

In the case of the back wheels]? may 'provide an elastic mounting comprising links L L, pivoted to the stri s EE at oneend and supplyin a bearing or the axle L at the ot er. etween the links L L and the curved ends L L of the strips E'E, I inter: pose the coiled springs L L This arrange befolded over ment, however, is not essential to my invenandat their other ends carrying the such angle-I V .o 1 lines in Fig. 1.

The use and operation of my improved gocart will perhaps have been made sufliciently clear by the foregoing. description of its parts. vWhen the device is opened out, it will be seen that the parts are sorelated to each other as to form a sort of trusswork which divides up the strain.- To collapse the-device when it is not in use, it 1s only necessary to grasp the handle A and one of the arm-rests D and all the parts will give on their pivots, so as to be brought together into a very compact form. take when colla sed are shown by dotted n order, to avoid confusion, the folding of the device has been illustrated as being brou ht about by maintaining the strips A A in t eir normal position and rotating the strips E E, and consequently the imaginary ground-line has been inelinedto the positionindicated by the lineX Y. The weight on the seat when the device is opened out will keep ,the parts in proper position ,no change being effected by pushing on-the han-. I dle A, since this isconnected Wit apart of the frame which supports the. forward wheels; It will be observed that the frames made by the strips A A and EE are connected by two pairs'of members, t links D D and the armsiD D, which are-substantially parallel when the supporting-frames are spreadthat is, when the device is in use.' This serves to lock the framework in its open 'position so that 'it requires a direct u ward pullv to co lapse the device; Thisv ma hes it im ossible that the o-cart should be folded up I 'rom any jar inci exit to its use.
