GO-CART OR PERATL'BULATOR.

Specification of Letters Patent.

Patented Oct. 8,1912.

Application filed March 2, 1910. Serial No. 546,928.

I '0 (all whom it may concern:

Be it known that I, ARTHUR J. ADAMS, a citizen of the United States, residing at 551 Fulton street, Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Go-Carts or lerambulators, of which the following is a specification.

My invention relates particularly to foldiug go-carts, or baby carriages, which are adapted to be folded into com-pact space.

The present invention constitutes an improvement on the go-cart shown in my Patents l os. 789,310, granted May 9, 1905, and

918,250. granted April 13, 1909, the improve ments relating particularly to the adjustment of the back for the seat and to improved means for attaching the wheel-forks, or supports.

My primary object is to provide an improved device facilitating the adjustment of the seat-back, whereby the back may be more readily adjusted to a position corresponding with a sitting posture or to a position corresponding with a reclining posture.

A further object is to provide, in connection with such device, means whereby the back and rear portion of the seat will be yieldingly supported.

A further object is to provide an improved connection for the wheel-forks, or wheel supports.

The invention is illustrated in its preferred embodiment in the accompanying drawings, in which- Figure 1 represents a side elevational view of a go-cart, baby carriage or per-ambulatorembodying my improvements; Fig. 2, a broken inner perspective View of the rear portion of the running-gear f arms and attendant parts; Fig. 3, a broken section taken as indicated at line 3 of Fig. 2; Fig. 4, a broken section taken approximately as indicated at line 4 of Fig. 1 and showing the back-adjusting means; Fig. 5, a broken perspective view showing a detail of the backadjusting means; Fig. 6, a detail sectional view taken as indicated at line 6 of Fig. 1; and Fig. 7, a sectional view taken as indicated at line 7 of Fig. 6.

In the construction illustrated, A represents the running-gear frame; B, pairs of wheels journaled on brackets B connected with the running-gear frame by pivots 1 adapted to fold beneath the running-gear frame in a well known manner; C, a handle connected by hinges 9 with the rear portion of the running-gcar frame and adapted to .fold forwardly upon the runninggear frame; 1), foldable brace-lmrs, or side-arms, connecting the upper portion of the handle with the front portion of the running-gear frame and forn'iing with the running-gear frame and the handle a triangular structure, said brace-bars serving also as a means from which the seat may be suspended; E, a seat having its front portion suspended by links 3 from the bars I); F, a back having its lower portion flexibly joined to the rear portion of the seat; F, improved means for adjusting and supporting the back in either a standing or reclining position; and G, a foot-rest adjustably connected with the bars I) in a well known manner.

The ru1ming-gear frame A may be of any suitable construction. In the form shown, it comprises horizontally disposed longitudinall y extending side members, or bars, 4 connected by cross-members 5 (one shown). The pivot 1 on each wlnael-ln'acket B is supported from the side-bar i: by a pair of mutually bracing brackets (3 and 7, as appears clearly from Figs. 2 and 3. The side-bar 4 is preferably of wood, and the bracket members 6 and 7 prc'lkirably comprise sheet metal stampings. The bracket member 6 comprises a plate 8 whose upper end is secured to the bar 1- by a bolt 9, said plate having interned vertical flanges 10. The bracket 7 comprises a metal plate 11 whose upper end is secured by the bolt 9, said plate having inturned vertical flanges 12 which fit within the upper portions of the flanges 10 and abut against the plate 8, said plate 11 also having an inturned lower flange 13 which abuts against the plate 8. The lateral flanges 10 and 12 of the brackets are secured together by a longitudinal rivet 1 1, and the plates 8 and 11 of the brackets are secured together by a transverse rivet 15. The plate 8 and lateral flanges 10 project beneath the lower end flange 13 of the bracket 7, and the lower ends of the flanges 10 allord cars which sup port the pivot 1. It will be noted that the two bracket members 6 and 7 mutually brace each other, so as to atl'ord a secure adjustment for the wheel-fork. This provision tends to prevent racking of the wheel-forks with relation to the frame.

Each hinge 2 comprises a hinge member 16 turned flanges engaging the edge portions of the handle-bar, and said member 17 has a pivotal portion 22 connected with the pivot 21. The hinge members have suitable shoulders (not shown) which abut against each other when the go-cart structure is in the uncollapsed condition. The cross-bar 5 preferably comprises a side-bar which extends between the hinge members 16 and has forwardly turned ends 23 which lie in contact with the plates 11 and 18. The forward end of the arm 23 is secured by the bolt 9, and the bolt 24 secures the rear portion of the arm. and the member 16 to the rear portion of the bar 4.

Each handle-bracing and seat-supporting device D comprises an upper link, or bar, 25 connected by a pivot 26 with the upper por tion of the corresponding handle-bar; a lower bar, or link, 27 connected at its front end by the pivot 28 with the front portion of the corresponding bar 4 and connected near its rear end by a pivot 29 with the front end of the bar 25. The bar 27 has a rearward extension which has spring connection with a pivotally connected member 30 which is releasably secured to the bar 25 by a locking device 31, this means being claimed in my Patent No. 925,741, granted June 22, 1909. The seat E has sideflaps 32 whose upper edge portions are connected with the bars 27.

The back F maybe of leather or pantasote 33 having connected therewith a marginal rod 34 which extends across the upper portion of the back and along the sidesof the back. The side arms of the U-shape member 34 have outwardly struck intermediate portions affording eyes, or loops, 35. The device F which co-acts with the loops 35'preferably comprise a pair of guide-rods 36 whose lower ends are pivot-ally connected with spring-supported levers 37 connected with the handle-bars, and whose upper ends are connected by pivots 38 with arms, or clips, 39 secured to the bars 25 of the handle-bracing and seat-supporting devices D. The rods 36, in the extended condition of the structure, extend upwardly and forwardly from their points of connection with the handle-bars, as clearly shown in Fig. 1; and adjacent to the pivots 38 the rods 36 are provided with offsets, or loops 40. The rods entend through the loops 35 of the seat-back, and in the standing position of the seat-back the loops 35 engage the loops 40. Each lever 37 may comprise a short piece of comparatively heavy rod having a shank 41 which extends transversely through a spring-housing 42 secured to a bar of the handle C and containing a coil-spring 43 upon which the shank rests. The housing 42 may be formed of sheet metal which has forwardly turned lateral flanges 44 embracing the sides of the handlebar, and forwardly turned shorter end flanges 45 which abut against the rear surface of the handle-bar. The clip, or housing, 42 is secured to the handle-bar by a bolt46. The flanges 44 are provided in the rear of the handle-bar with slots 47 through vhich the shank 41 extends. The inner end of the shank 41 is turned forwardly to afford a pivotal portion 48 which is connected with a pivot-clip 49 secured by the bolt 46. The outer end of the lever 37 is provided with an eye 50 which is engaged by a hook 51 with which the lower end of the rod 36 is provided. It will now be understood that When desired the back may be disengaged from the loops 40 and lowered to the dotted position shown in Fig. 1, the loops 35 of the back sliding upon the guide-rods in this move ment. In the reclining position of the back, the loops 35 are supported upon the eyes 50 of the levers 37. The springs 43 will yield under pressure, so that the back will be yieldingly supported. The foot-rest G is of the adjustable type shown in my Patent No. 927,089, granted July 6, 1909, and need not be explained in detail.

The pairs of wheelforks at opposite sides of the cart are preferably connected-together by collapsible link mechanism (not shown) of the character disclosed in my Patent No. 913,345, granted February 23, 1909. It is sufficient to state here that said link mechanism is of a character to permit the wheels to be folded in pairs beneath the running gear frame. It may be remarked that the rear transverse connecting bar 5 of the running-gear frame in my present construction is disposed at theeXtreme rear end of the frame in position to protect the link mechanism connecting the wheel-forks, so that a person may place a foot on the cross-bar 5 in assisting the carriage up a step, for in stance; and because of the disposition of the bar it will be inconvenient and unnecessary for one to place the foot upon the link mechanism which might cause injury to the mechanism.

It may be remarked that the back F is ordinarily equipped with side-flaps (not shown) which are folded with relation to the back when the latter occupies a standing position, and which are extended in planes at right angles to the back and connected to the foldable brace-bars D when the seat 00- cupies a reclining position, in the manner shown in my above mentioned Patent No. 918,250.

The manner of adjusting the back in accordance with my improved construction will be readily understood. In the standing position of the back, the lateral loops 35 of the back engage the loops or depressed offsets 40 at the upper front portions of the guide-rods 36. WVhen it is desired to bring the back to a reclining position, it is only necessary to lift the back somewhat to dis engage the loops 35 from the offsets 40, whereupon the loops will slide freely upon the rods 36 until they are brought to bear on the eyes 50 of the short levers 37 at the lower rear ends of the rods 36. The adjustment in either direction may be quickly and easily effected while the baby is in the carriage. It will be noted that the construction is such that the back-adjusting mechanism will not interfere with the folding of the carriage. That is to say, when the locking devices 31 are released to permit the brace-bars D to be flexed and the handle (l to be folded forwardly upon the runninggear frame, the mechanism F will. not interfere with the folding operation; and this is true regardless of the position of the back F. In the folding operation, the lower rear ends of the rods 36 are free to slip through the eyes 50 of the levers 37. It will be understood that this is a necessary arrangement owing to the fact that in the operation of folding the cart the bars 25 which carry the arms 39 and the handle-bars have a rel ative movement toward each other about the pivots 26.

The foregoing detailed description has been given for clearness of understanding only, and no undue limitation should be understood therefrom, but the appended claims should be construed as broadly as permissible in view of the prior art.
