To all-whom it may concern: 7

Be it known that we, ERNEST TIMMER- HOFF and FRANK F. TIMMERHOFF, citizens of the United States, residing at \Varsaw, in the county of Kosciusko and State of ludiana, have invented certain new and useful. Improvements in Folding Go Carts,- of which the following is a specification.

'The present invention relates to baby carria es of the kind generally designated as folt iing go-carts and which are adapted to be reduced to a compact form for convenience of handling and storing and not be in the way whenset aside, as when not required for immediate service.

i For a full understanding of the invention and the merits thereof and also to acquire a knowledge of the details of construction and A the means for" effecting theresult, reference is to be had. to the accompanying drawings. 1

.While the invention may. be adapted to difierent forms and conditions by changes in the structure and minor details without departing from the spirit or essential features thereof, still the preferred embodiment is shown in the accompanying drawings, in which:

U-form and consistsof side bars 1 and a cross bar 2. The side bars 1 curve upwardly at their front endsand the portions joining the bars 1 and 2 are made rounding. rear ends of the side bars 1 are widened to provide extensions 3, wardly and rearwardly. The bars 1 and 2 are preferably tubular and are formed of a single length of tubing bent in the form sub stantially as shown. The extensions 8 may form a part of the bars 1 or be welded or attached thereto in any substantial. way.

'The wheel frames are pivoted to the side bars 1 of the main frame so as to fold up ward, and inward close to said main frame.

Each wheel frame consists ofa longitudinal bar 4, legs 5 and (3 and braces 7 and 8. The front legs Bare straight, whereas the rear legs (3 curve rearwardly to add to the stability of the device when the sameis adjusted for the infant or child to occupy a recum I bent position. 7 The upper ends of the legs 5 and (iproject above the ltmgitudinal bar 4 and extend laterally thereover and have their terminal portions bent upward so as to engage under the bars 1 and bear against the outer sides of saidbars, as shown at 9.

The

which project up- The longitudinal bars 4 project beyond the legs 5 and (l and are mounted in eye bolts 10 which constitute bearings therefor. The braces 7 and 8 have off-sets near their ends to throw the main portions of said braces inward from a plane passed through the longitudimil bar 4- andthe legs 5 and 6. A spindle 11 is fitted to the lower end of each of the legs 5 an'dG and is adapted to receive a wheel in the manner well understood. A keeper 12is provided upon each of the braces 7 and S and consists of a short bar fastened at one end to the brace and'having its opposite end portion spaced from the braces frame.

frame consists of side cross member 14. The front lock frame is mounted upon a rod 15 which is supported at its ends in the side through openings in the side members 13.. The cross member" 14. is curved upward between its ends to afford greater clearance at a. middle point and to give additional strength. A. rod 16 is supported at its ends in the side members 13 and forms, a rest for the frpnt end of the seat;17. The side members lilrprofzect above The front lock ltli ' downwardly and is secured to the ends of sai whereby t ends of the body bars 18.

I ment of the side fttl ' rear lock the rod 15 a distance to sup ort the front When the device is unfolded and in readiness for service, the lower ends of the side members 13 engage the keeper 12 applied to the front braces 7' thereby preventlng Outward movement 0 the wheel frames wheel frames bemg prevented-by engagelock framewith the inner sides of the braces Outward movement of the wheel frames is also prevented by the bent ends 9 of the front and rear legs 5 and 6 in the manner herein stated.

The rear.lock frame is similar in construction to the front lock frame and is pivotally connected with the main frame of the runnin gear and consistsof side memhere 19 ang'a lower cross member 20. The side members 19 do not project above the plane of the sidebars land are mounted pon a rod 21 which is supported at its ends in the'rear portions of the side bars 1. v.The

frame braces and stays the rear ends of the wheelframes by engaging the keepers fitted to the rear bracesS the inner sides of said braces. The

handle bars 22 are connected at'their upper ends'by the handle or cross bar 23 and are mounted near their lower. ends upon a rod 24, which is supported at its ends in the extensions 3. cross bar 25 connects the lower ends of the handle bars 22. A brace 26is attached at a middle point to the lower cross bar '25 an inclines outwardly and bent u wardly a t27 and d cross bar 25 and are thence bent-forwardly, as shown at 28', said forward extensions bein I ceive the u per ends of the side members 19, lie rear lock frame is caused to move slmultaneousl with the handle bars when folding or un olding the same. Latch rods 29 are mounted in the lower ends of the handle bars 22 and, are adapted to enter openings 30 provided inthe extensions 3, thereby securing the handle bars in a given position when the go-cart'is adjusted for service. A' U-bracket 31 is secured to the "lower cross bar 25 and to the middle portion of the brace 26, and sup orts the inner ends of the latch rods 29. prings 32 mounted upon the inner end portions of the latch rods 29 normally exert a pressure to throw the latch rods outward and hold their outer ends projected into the openings 30, said springs being confined between the upright ends-of the bracket 31 and stops fitted to the inner portions of the latch rods 29 a short istance from said bracket. The innerends of the latch rods 29 are bent, as shown at a transverse slot 34 33, and pass throughconnectin formed in a plate 35 mg its vertical edge portions bent to promward movement of said the main running members 13' of thefi'ont.

I preferabl slotted; to rethe lower. cross bar 25 and the rod 24, sai plate havvide guides 36to receive a slide 37 by inenns of which the latch rods are operated. The slide 37 is provided at its upper end with a head 38 to receive the pressure of the hand or foot when it is required to effect release of the latch rods 29 from the extensions 3 of ear frame. An opening e lower portion of the 39 is formed in t slide 37 and is of such shape that the opposite edges upwardl ward movemento bent ends 33' of the converge, hence downlatch rods inward and withdraws their outer ends from the openlugs 30.

The body bars 18 are pivotally connected t their front ends to the upper ends of the side members 13 and are pivotally connected j at their rear ends to the handle bars 22 bolts or like fastenings 40. Rods 41 have connection at their ends with the body bars and support the side pieces of the body.

he rear end of each rod 41 is offset and of the body bar 18. The front ortion of each rod 41 is off-set and provid ed with a loop 44 which forms attaching means for the strap 45, and said rod being secured to the front end of the bar 18 in any manner,

by being fittedjnt'o an openin ormedt erein. A spring 46 is mounte upon each guide rod 43 and supports the rear .end of the rod 41, said spring being of sulficient tension to support the body and the weight of the infant or child. A brace 47 connects the lower end of the guide rod 43 with the bolt or fastening 40. In the event the slide 37 moves the of the bodybars '18 being of wood, their end portions may be tlherepn, said cuffs havin openings to receive t e parts thereto.

The body consists of a seat 17, a back 48, flexible sides 49 and a boot 50, said boot consisting of an apron and flexible sides, and provi ed at its front end with a loop 51 to receive the cross bar 2 of the mainframe. Headed studs 52 project upward from the cross bar-2 and engagewith opposite edge portions of the loop 51- to prevent lateral movement of the boot and to hold the same in a given position upon the cross bar 2. The headed studs 52 also serve as means of attachment of the rings 53 connected to the foot rest 54 provided at the front end of the boot so as to hold the latter elevated when the body is adjusted to admit of the infant or child reclining. This feature is shown most clearly in Fig. 5. The seat 17, as also the back 48, is constructed of ri 'd material which is upholstered to provit yielding surface. to the seat 17 so'as to pivot .or hilfg'e, thereby admitting of the back beingra-ised (alowered I or adjusted-to any angularipmition Th8 astenings connecting the supporting reinforced by cufi's slipped e a soft or The back 48 is connected bolts or fastenlngs 40.

to the rear side of the back 48 receives hor1 erases a flexible sides 49 are provided at their upper edges with a hem or openlng to receivethe rods 41 from which the body is suspended.

A. bail is adapted to support the back 48 in an adjusted position and its side members terminate in eyes through which pass the A keeper 56 applied zontal portion of the bail-55 and limits the adjustment thereof; The bail 55 is held in an adjusted position by tightening the bolts or fastenings 40. The front end of the seat 17 is supported upon the transverse rod 16 and the back 48 rests upon the horizontal portion of the bail 55, whereas the boot 50 is suspended from the'cross bar 2 either by means of the loop 51 or the rings 53, according to the adjustment of the body.

Wheinthe device is set up for use it presents the; appearance substantially as shown in Fig. 1, the front and rearlock frames engaging the inner sides of the braces of the wheel frames and the keepers applied to said braces, thereby holding said wheel frames rigidly. The latch rods 29 enter the openings 80 of the extensions 3 and secure the handle bars, thereby preventing movement thereof so that the go-cartmay be handled by manipulating the handle bars in the 30' manner well understood. When it required to fold the go-cart or reduce the same to a knocked down or compact form, the

latch rods 29 are released by pressing downwardu'pon the slide 37, thetupper ends of the handle bars being thrown forward and downward with the result that the rear lock frame is withdrawn from engagement with the rear braces 8 of the wheel frames by the forward extensions 28 of the brace 26 engaging with the side members 19 of said rear lock frame. As the handle bars are moved forward .and downward, the body bars 18 .pivotally connectedthereto are also moved forward. and downward, and by reason of their connection with the side members 13 of the front lock frame, the latter is moved so as to throw the lower portion upward into the plane of the main frame of the running gear. As the front lock frame'n'loves, it comes in contact with a trip 57 projected inward from one of the wheel frames and folds the same, and a moment later, said lock frame comes in contact with a similar trip 58 pro ected inward from the other .wheel frame and effects a folding thereof.

By having the trips 57 and 58 set, the one 111 advance of the other, interference of one wheel frame with the other, when folded,

avoided. The wheel frames are held folded by the front lock frame coming between and bearing against the inner sides of the trips 57 and 58. When the handle bars are thrown upward and rearward 1n the act of unfolding the go-cart, the front lock frame engages with the front braces 7 of the wheel:;

frames and throws the latter downward and outward intov vertical position. A st 'ap 59 connects the lower edge of the foot rest with the crossniember 14 of the front lock frame, thereby limiting the forward movement of said foot rest when pressure is exerted thereon from within the boot.
