To @ZL whom/Lft may concern:

'Be it known that I, IsIDoE RAUTENBERG, a

`citizen of the United States, residing at Cnicago, in the county oi Cook and State of Illinois, have invented certain new and useful Improvements in Folding Sleds or Gro-Carts and Ido hereby declare the following to be a full, clear, and exact description of the in ventiomsuch as will enable others skilled in the art to which it appertains to make and `use the same.

`My invention relates to a novel construc- `tion in afolding sled and go-cart, the object being to 1provide a device of this character which wil accommodate either one or two children and which when not inuse may be folded to .occupy relatively very small space tudinal section of a folding go-cart constructed in accordance with my invention and adapted to carry two children, the same being shown in position for use. Fig. 2 is a similar section showingthe same in its folded position. Fig. 3 isa central vertical trans- `verse section on the line 3 3 of Fig. 1. Fig. 4L isa central vertical longitudinal section of a go-cart constructed in accordance with my invention and adaptedto seat only one child. Fig'. 5 is a similar section showing the same in itsfolded position. Fig. 6 is a detail vertical transverse section on the line 6 6 of Fig. 4.

1Referring now to said drawings, my said gocart comprises two levers 1 and 2, bent between their ends to substantially a Z shape and being pivotally secured together midway betweenithe ends of the intermediate bent portions 3. All parts specified are arranged `in pairs; but for purposes of ease of description I shall refer to said parts singly, for the reasonthat I believe that the same will be more readily understood. At its lower end said lever 2 is pivotally secured to one end of `a -runner 4, the ends of the latter being curved upwardly and same being provided between its ends with a longitudinal slot 5, extending from a point adjacent the pivotal connection of said lever 2 therewith to a point adjacent the forward end of the said runner. The said lever 1 is provided with a projection@ adapted to pass through said slot 5 and movable from end to end of the latter. On said projection ispreferably mounted an antifrictioneroller 7, (shown in Fig. 6,) which is adapted to run on the lateral flange 8, disposed on the lower edge of said runner. The upper free end portions of said levers 1 and 2 cons-titute handles by means of which the said sled'is propelled, the lever 1 being preferably of greater length than the lever 2 and the pairs of said levers being connected at their extreme free ends by means of cross-bars 9 and 10. Iivotally secured to said lever 1. between the pivotal connection thereof with said lever 2 is a link 11, which at its free end is pivotally connected with a similar link 12, pivotally connected at its other end with said lever 2. The pivot 13 between said links 11 and 12 is provided with a projection which extends through a longitudinal slot 14 in a vertically f disposed post 15, secured to the cross-bar 16, upon which said levers 1 and 2 are 'pivotally mounted. The said links 11 and 12 constitute the arms of the seats 17 of said go-cart, which latter are mounted upon links 18, pivotally secured together at their nee ends and at their other ends being pivotally secured to arms or projections 19 on said levers .1 and 2, between the pivot 16 thereof and the point of connection of said links 11 and 12 therewith. The said pivot 13 and the pivot 20 between said links 18 are `of the elbow type, which are free to turn in one direction only, being limited against turning in the opposite direction by contact of the ends of said links with each other, said pivot being iree to permit said links 11 and 12 to move downwardly at their free ends in folding saidV cart and said links 18 being free to move upwardly duringl the same operation. Thumb-nuts 21 are provided at the points of pivotal connection of said links 11 and 12 with said levers 1 and 2 and these are adapted to engage slotted quadrants 22, pivotally 'connected with arms 23, having pivotal connection at their lower ends with said links 18, and to which the backs 211 of said seats 17 are adjustably secured. To support said links 11 and 12 in their raised positions, slotted arms 25 are pivotally secured thereto between the ends of said links, and through the slots therein threaded projections on said levers `1 and 2,

IOO

on which thumb-nuts 26 are disposed, pass,

said thumb-nuts being adapted to clamp said arms 25 in position to support said links 11 and 12. Secured to said levers l and 2 IIO between their ends are plates 27, the lower ends of which are connected by the curtain '28, which, together with said plates, constitute a box or receptacle to receive and protect the feet and legs ofthe occupants of the go-cart.

In order to render my said go-cart adapte able for sleeping purposes, I provide 'depending hinged plates 29 at the free ends of the seats 17, each of said plates being in the shape of a right-angled triangle and relatively oppositely disposed, so that when raised to a horizontal position they will close the open- .in f sets 17, said plates being supported at their free ends inl any desired manner-such, for instance, as by means of hooks disposed on the frame and adapted to enter openings in the free ends of said plates, as shown in Fig. 3;

In order to rotect the occupants of the golever 1 a sha e-roller 30, on which a watercart from rain, I preferably dispose on said pioof curtain 31 is disposed, which is adapted to be drawn to extend horizontally over the seat portion of the carriage and is adapted to be secured at its free end to a cross-bar 32, disposed between the free ends of slotted telescopic extensions 33, disposed on the lever 2, each of the said extensions being guided by means of projections on said cross-bar 10, passing through said slots, and by means of the thuinb-bolt 21, also passing through the slot therein and adapted to clamp said extension to the lever 2 simultaneously with said quadrants 22.

In Figs. 4 and 5 I have illustrated a modified form of construction of my said go-cart which is adapted to seat only one child. The

'construction differs slightly from that shown in Figs. 1, 2, and 3 in that the levers 34 and 35 are of slightly different shape than the levers 1 and 2 and in that the seat-supporting bar 36 is provided with a longitudinal slot 37, in which a projection 33 on the upper free end of the lever 35 travels. The said bar 36 is provided between its ends with a projection'39, to which the back-supporting bar 40 is pivoted, the said pivot being disposed above the upper edge of said bar and the slot 37 being curved upwardly at its rear end and extending into said projection 39. The rear end of said bar 36 projects beyond the rear edge of the lever 34 and carries the thumbbolt 41, by means of which the quadrant 42, supporting said bar 40, is clamped in any desired position. The said lever 34 is provided between its ends with aprojection 43, through which the pivot of the bar 4() extends, and thiisforms also the pivotal connection of said bar 36 with the lever 34. tuting the arm of the seat, is pivotally secured at one end to the lever 34 and at its other end is pivotally secured to a lever 45, which is pivotally secured between its ends to the forward end of the bar 36 and at its between the opposing free ends of the ticularly advanta that the back of tlie seat portion can be adof oppositely-dispcsed lazy-tong A link 44, constilower free end carries the foot-rest 46, which is hinged thereto, said hinge being so disposed that when said foot-rest 46 is practically horizontally disposed it is supported by contact of the rear projecting edge portion thereof with vthe lower end of said lever 45.

As indicated in Figs. 1 and 4, the runners 4 and 47 of the device may be replaced by the wheels, (indicated in dotted lines,) this being accomplished in any suitable manner.

It will be noted that my said go-cart folds up in a relatively very small space and is adapted for all uses to which devices of this character are put. The construction is par- Ueous by reason of the fact justed as desired, this being, so far as I am informed, an entirely new departure in folding go-carts. The construction, while efficient, is also very durable, the number of parts being relatively small and all connections being made with a view to affording the greatest possible strength.
