VINCENT F. PIOKERT, OF ATLANTA, GEORGIA.

GO-GART.

Specification of Letters Patent.

Patented April 13, 1909.

Application filed October 30, 1908. Serial No. 460,334.

To all whom it may concern:

Be it known that I, ViNcnN'r F. PicKER'r, a citizen of the United States, residing' at Atlanta, in the county of Fnlton and State of Georgia, have invented new and useful Improvernents in Go-Carts, of which the following is a specification.

This invention relates to g'o-carts convertible into a cradle and particularly intcnded for indoor' use as well as on porches and in `yards of dwellings, and the primary object of Vtages in view, the invention consists in the construction and arrangement of parts which Will be more fully hereinafter specificd in preferred form and illustrative of one embodiment of the invention.

In the drawings: Figurc 1 is a pers'pective view of the frame and handle of a g'o-cart embodying` the features of the invcntion and showing the body or basket removed and portions of the frame clevatcd to adapt the cart for use as a cradle. Fig'. 2 is a sectional elevation of the cart showing' the body in place, the body being' elcvated and free to swing as a cradle. Fig'. 3 is a side elevation of the cart and body shown collapsed or reduced to compact form and disposed under a bed, the latter being shown in dottcd lines. Fig. 4 is a detail perspectivc view of the body shown arrang'ed for use. Fig'. 5 is an end elovation of the body or basket shown collapsed.

The

numerals

1 and 2 designate axles provided With suitable Wheels 3 and pairs of frame bars or arms 4 and 5, the frame bars or arms 4 being terminally fixed to the aXle 1 and the frame bars or arms 5 to the axle 2. The frame bars or arms 5 intersect the pair of frame bars or arms 4 and extend inside of the latter, the intersecting' pairs of frame bars being 'fulcrumed and connected by cross rod 6, the said rod also serving` as a tie means for the pairs of frame bars. The pairs of arms 4 and 5 are crossed at such intermediate points with relation to each other that the upper extremities thereof will project equally in reverse directions .from the rod 6 and to the free ends of each pair of arms swinging hangers 7 are applied and comprise depending arms 8 movably attached to the ends of the .frame bars or arms 4 and 5 and connecting` rods 9. The frame bars or arms 4 and 5 also have pairs of toggle links 10 and 11 movably attached thereto respectively, and pivoted to each other by fulcrum pins as at 12, the ends of the links 10 being applied against the outer sides of the links 11. Operating bars 13 are also fulcrumed on the outwardly projecting ends of the rod 6 and bear against the outer sides of the frame bars or arms 4, said Operating,` bars being connected at one end by a cross bar 14 and having the extremities thereof fulcrumed on the rod 6 provided with angular extensions 15 which practically serve as bell cranks and have their free ends beveled as at 16, see Figs. 2 and 3. The bars 1.3 and cross bar 14 unitedly constitute a handle for pushing the cart or device as well as an Operating means for raising and lowering the frame of the gocart, and the said handle or Operating means is thrown over in o pposite directions to adjust the frame bars. Draw links 17 are connected to the angular extensions 15 and the fulcrum pins 1.2 of the links 10 and 11 so that the movement of the handle or operatingl means in opposite directions over the framework or the body supporting frarzne of the go-cart will operate the parts of the frame in such manner that the Wheels 3 will be drawn toward each other when the device is arranged for use as a cradle and as shown by Fig. 1, or said Wheels will be forced apart togetherwith their axles when the Operating handle or the connected bars 13 are thrown over in a direction reversc to that shown by Fig. 1 or as illustrated by Fig. 3. The toggle links 10 and 1.1 and the draw links 17 constitute the contractinc` and oxpanding' means for the

axles

1 and 2 and the wheels 3 through the medium of the pairs of frame bars 4 and 5, when actuatod by the operating handle in the manner just explained or when the Operating handle is thrown over the axle 2, the draw links 17 are depressed and force the connected ends of the toggle links 10 and 1.1. downwardly and draw the pairs of frame bars toward each other, whereas when the operatinq handle is thrown over the axle 1 the draw links 17 pull upwardly on the toggle links 10 and 11 and expand or release the pairs of frame bars 4 and 5 and permit the latter to depress into a substantially horizontal plane, as shown by Fig. 3. The two adjustnients can be readily carried on without requiring the manipulation of releasing` or fastening devices. *When the frame bars are in the position shown by Fig. 1, the beveled ends 16 of the extensions 15 forming,` parts of the bars 13 frictionally bear on the upper edO'es of the links 10 and serve as a looking means or an effective auxiliary to prevent accidental collapsing of the frameV bars, and such engagement of the ends of the extensions With the links 10 also prevents too loose movenient of the Operating handle ccmprising the bars 13 and 1-1.

The go-cart or improved device also embodies a basket or body 18 shown in detail in two conditions by lfigs. 4 and 5. This body or basket will be preferably formed of woven willow or analogous open material and is supported in the hangers '7, as shown by Fig'. 2, When the g'o-cart is arranged for use as a cradle but is let down on the axles when the go-cart is adapted for ordinary trundling` purposes or when collapsed, as shown by Fig. 3, the hangers easily and positively cooperating with the body 01' basket to raise it or lower it in accordance with the movement or adjustment of the OperatingI handle either over the aXle 2 or the axle 1. The bed or basket 18 is collapsible and comprises a bot-- tom 19 having' side fiang'es 20 to which opposite side members 21 are hing'ed and adapted to be inwardly folded. The one side meirber 21 has the ends 22 hinged thereto and the eoperating side is formed with inner recesses or grooves 23 to removably receive the free extremities of the said ends 22, the grooves or recesses 23 being formed in the ends of the one side, as shown and prevent accidental collapsing` of the sides and ends when the bed or basket is arranged for use. The bed or basket may be collapsed as shown by Figs. 3 and 5, the ends 22 being first released and folded inwardly against the inner side of one of the side members 21 and the latter with the ends then turned downwardly between the flanges 20 of the bottom 19 and the remaining' side 21 then folded over the previously folded side member carrying' the ends. This collapsible structure of the body or basket renders the same convenient for shipment or storage and also permits the gocart as a whole to be temporarily disposed under a bed or other device or article of furniture when it is desired to place the go-cart where it may be readily accessible without occupying unnecessary floor space. To prevent the body or basiiet from slippin' on the hangers, the bottom 18 has pairs of spring` clips 24 secured to opposite cxtremities on the lower side to separa bly receive the rods 9 of the hangers. The rcds 9 readily slip into and out of the said clips when the body is raised and lowered.

The body or basket is of such length as to readily serve as a cradle body or it may be removed entirely from the vehicle part of the device and placed on a floor to hold a child in a nursery or on a porch or lawn and thus serve as a support or a play receptacle. The frame of the go-cart will be constructed of light metallic bars strong'ly connected and the device a whole may be cheaply manufactured.
