Application filed July 8, 1907. ySerial No. 382,625.

To all whom it may concern:

Be it known that I, EDWARD C. MOORE, a citizen of the United States, residing at Philadelphia, Pennsylvania, have invented certain improvements in Gro-Carts, of which the following is a s eciiication.

My invention re ates to folding go-carts and is in the nature of certain improvements upon the construction shown in my application for patent, filed Febrilary 27, 1907, Serial No. 359,560; the object of my present invention being to simplify the construction; to increase the facility with Which the structure may be operated; to provide an adjustable foot-rest therefor', and to render`such structure more compact when in the folded Other features of my invention will be fully pointed out hereinafter, reference being had to the accompanying drawings, in which:

Figure 1, is a'side elevation of my improved go-cart; Fig. 2, is a front view of the same; Fig. 3, is a side elevation showing the structure partially folded; Fig. 4, is an inverted plan View showing the Wheels folded against the body of the cart, and Figs. 5, 6, 7, 8, 9, 10, 11 and 12, are enlarged views illustrating detached parts of my improved structure.

l, 1, represent the side frames, to which side bars 2 at the back, and side bars 3 at the front, are pit/totally connected at 4 and 5, respectively, and 6, 6, represent. side arms pivotally connected at 7 and 8, respectively, to said front and rear side bars 2 and 3. The side frames are provided With down- Wardly depending extensions 9 and 10, to whichbrackets 11 and 12 are pivoted, and hinged at 13 and 14 to these brackets are the arms 15 and 1G. The arms 15 carry the rear wheels 17 and the. arms 16 carry the front wheels 18; suitable journals being provided at the ends of said arms. The arms 15 and 16, and the brackets 11 and 12 to which they are hinged, are fully shown in Fi s. 5 and 6. When in the position shown in lig. 1, the structure is locked against collapsing, by means of a cross-piece 19, made of Wire and shown in Fig. 7; the projecting ends 2O of which pass through slots 21 in the side frames l.. r1`he cross-piece 19 is arranged to be held in place by spring tension, and the ends 2O coact with notches 22 formed in plates 23 secured to he lower ends of the tured end blocks 27 secured to ears 28 car- A ried by arms. The arms having a pivotal connection with the side frames, such springs serve as cushions or resilient supports when passing over obstructions and give the Wheels an Yopportunity for partial separation against the tension of said spring without danger of destroying their proper relative position under ordinary circumstances. To prevent the Wheels folding under thestructure, the front arms 16 have lugs 29 Which lie under projections 3'0 carried by the extensions 10 of the side frames when in the position shown in Fig. 1.

At the front ot' the structure, I provide an adjustable foot-rest 31, which is pivoted at 32 to a pair of swinging arms 33 pivoted to the side frames 1 at 34, and supported at its orward end by a 'Wire oke 35 pivotally connected to the front side bars 3 of the frame. The arms 33 which support this foot-restare slotted at 3G, and a'wire crosspiece 37 shown in Fig. 9 is provided with ends 3S which enter said slots. This crosspiecc is carried byl a wear-board 33 disposed between and supported by the arms 33; being held to said wear-board by staples 37a. Carried by the front side bars 3 of the structure are brackets' 39, one of which is shown in Fig. 10, having a series of projections. 'When in the lower-most position, as shpwn/infullwlineaFig. 1, the ends of the cross'piece 37 passing through the arms supporting the foot-rest engage the projec` tions 40. When in the extreme position shown by dotted lines in Fig. 1, theends of said cross-piece restl on projections 41, and when in the mid-position, shown also in dotted lines, the ends of said cross-piece rest on the projections42; the construction being such that the ends of said cross-piece may bedisplaccd along the slots 36 so-as to clear said projections 40 and 41, and ,when moved into the various positions, they will be held in place by thc inherent resiliency ofthe cross-piece 37. The foot-rest is provided with a serics 'of notches 43 on, its under side so that thc wire yoke 35 supporting the same may be shifted relatively so as to rear side bars 2, The side frames are sechange the angle of said foot-rest. I The footrest may be mounted in' several positions by engagement with the apertures 44 in the arms 33, and the eXtra notches on the under side of saidfoot-rest are for the differing positions of the supporting yoke when such foot-rest has been lowered. The foot-rest 31 may lie extended in a straight line from its support-ring, arms 33 by releasin front engagement with the notc es 43 on the under side of said foot-rest. To maintain said yoke in its engagement with said notches, I provide spring members 45 which lie below the engaging portion of said yoke. When the foot-rest is extended in line with its supporting arms, it will be held in a horizontal position by stops 45 on the arms 33.

The arms 15 and 16 supporting the wheels are hinged at 13 and 14 to brackets 11 and 12, which are pivotally connected to the side frames, and the bracket 11 is provided with teeth 46 meshing with teeth 47 of brackets 48 carried bythe rear side ainis of the structure; the enlarged view Fig. 11, showing said brackets. The brackets 4S have a fixed relation to the notched plates 23 carried by said side arms, and when it is desired to collapse the structure, it is only necessary to move the ends 2() of the crosspiece 19 from their engagement with the notches 22 of said plates. This is readily accomplished by engaging the loop49 of said cross-piece 19 and pulling the same rearwardly, when the ends Q0 will spring forwardly, as said cross-piece is secured at the points 50 to the under side of the scat board. l

The side arms of the structure are adjustable rearwardly to the position shown in Fig. 1 by C ytted lines; the notched plates )l being provided with two notches Q2 for engagement with the ends 20 of the crosspiece 19, and in the adj usted position shown in Fig. 1, tlieciids 20 are in eiigageinent'witli the lower notch. A back 51 is disposed between the rear side arms, pivoted at 52 to said arms so as to be movable independently of the rear side arms, This back is adjustable and is supported in its various positionsI by means o't' ayoke 53 pivoted to the rear side arms at 54 as clearly shown in Fig. 12, and arranged to engage lugs 55 carried by the side members of said back 51. lflicn in the position shown by fiillliiies, Fig. 1, the back is held by hooks 5G of the arms of said yoke engaging pins 57 carried by the back` the lower portion of the yoke lying against Vsaid back. When changed to the other positions shown, said hook will be released from the pin. The back may also be maintained in a forward position. 'llie sideai'ins of the back, and the side arms of the front aie provided \vi.li side guards 58 pivoted at 59 to said arms.

To collapse the structure, it is necessary; as before slated., to remove the ends 2O of the the yoke cross-piece 19 from their engagement with the notches 29, of the plates Q3 carried by the side bars of the back, by gras ing the loop 49 and piillin the same and `t en the structure may be olded forward to the position shown in Fig. 3. lVhen in this position, the hinges of the arms supporting the wheels are horizontally alined so that said -arins with the wheels may be folded down against the body in the manner shown in F ig. 4.. When in such position, the structure is compact enough to be placed in an ordinaryA dress-suit case. i
