CHILDS FOLDING CARRIAGE.

make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to childrens folding carriages. 7

It has for its object an improved carriage adapted to be folded into smallicompass, or unfolded to present a long wheelbase, an adequate seat, a capacious boot and a convenient handle bar.

The locking of the carriage into the folded or unfolded position is readily accomplished by mechanism which may be operated by a pedal, while the folding or unfolding is conveniently accomplished by swinging the handle bar by which the carriage is ordinarily pushed.

A very important part of my invention is the withdrawing of both the rear and front wheels up under the arms and having the front and the rear axle drawn up against the bottom of the seat. This affords a very convenient deposit place for the wheels and when the carriage is in folded position, minimizes the compass of the package. This is accomplished without in any way weakening the axle by providing collapsible wheels in respect thereto, so that there is no danger of staggering or wabbling wheels.

In the drawings :Figure 1, is a side elevation of the frame without the covering. Fig. 2, is a front elevation with the covering. Fig. 3, is a side elevation of the folded carriage with the covering. Fig. l, is a section through the center of the carriage showing the operating parts in elevation with the covering removed and with the spokes not shown to avoid confusion. Fig. 5, is an enlarged detail of the mechanism under the seat. Fig. 6, is an enlarged detail of the boot and seat back, in their folded position.

For convenience of description, the seat bottom will be considered as the rigid or stationary part of the Vehicle, to which is Specification of Letters Patent.

secured certain frame pieces that will be mentioned. and around this seat part and frame pieces swing, on pivotal connections, the various foldable or movable parts of the carriage.

i 1, indicates the seat member, to'whiclrare secured at the back, posts 3. The arms at the front of the -arriage, risefronithe seat 1 parallel to the posts 3 and cross above the seat 1 in a proper curve for the comfort of the child in resting his'arnnan'd are fas-' tened to the posts 3. These mcmbersalso extend below the seat forming hanger 2 and for convenience of reference that part directly parallel with the seat is characterized as 9. in' the drawings. The posts 3 also extend below the seat forming the hangers 3 The boot of the carriage is formed by an independent frame 4 andel, which is pivotally connected with the cross bars 1 that support the seat member 1, and this boot is arranged tofold upward and backward over the scat member, as in the positions shown in F 4 and 6H At the front of the boot the cross rod 4 is secured by suitablebracket members 4". This cross rod is arranged to engage under the hook t which is secured to the back 5, the latter being pivotally connected at the rear of the seat 1, or to the bracket 5 that is itself secured to the seat member 1. The hook 4 has a character of a sliding latch controlled by a spring 4L. bars 6 and (3 engage between the spaced back 5 and the posts 3 connecting the upper port-ion 7 of the back 'collapsibly with the lower portion. The back is held in its adjustable position, that inclines with respect to the seat 1, by a link 8 pivoted to the arm 2, and securedby a sliding pivotal connection 8 to the guide rod 8* on the inclined back 5. The boot is held in outstretched position by the rods 48 at either side which are pivoted to the hangers 2 and which may engage the boot in several places, the holes 42 affording adjustment in the height of the boot. The boot may be folded up and over the seat member and over the inclined back, which is folded down against the top of the seat member, (as shown in Figs. 1, 2 and 6) and is locked in place by the catch l. The strap -10 on the bottom of the boot member, may be used to carry the collapsed carriage.

To acomplish the important feature of folding the wheels and axles into a close Pivoted side 7 in Fig. 2).

relation with the bod of the carriage, without collapsing the wheels and axles, I employ several levers and links. The rear axle 14 carrying the rear wheels 15 is attached to the C-spring 10, which in turn 1s plvoted to the hanger 3 by the pivot 3 so as to act as a radius arm. The front axle 16*, carrying the front wheels 16, is attached to the C-spring 17, that in turn is pivoted to the front hangers 2 so as to act as a radius arm. These two axles are connected with the movable handle of the carriage by linkage, which is composed of the link 12 pivoted to the upright member 13 of the handle, Wl'llCll in turn is pivoted to the post 3. At the other end of the link 12, is a lever 11-, which is riveted to the C-sp-ring 10 and which hasa bell crank arm 11 (Fig.4). This bell crank arm is connected with the C-sp'rin'g 17 of the front wheel by the link 18, which is provided with a pin that engages i'n a sharp bend of the spring. The bent link 18 is bent to snch a shape that when in the collapsible position, as shown in Fig. 4, it runs parallel with the seat and will engage very close thereunder.

1 is a cross bar connecting and bracing.

the hangers 3.

The levers, the linkage and springs are identical on each side so that the description of them at one side is sufficientfor the other side.

The wheels and frame are kept their respective folded position by locks which are operated by the lever or pedal 19 rigidly secured to a lock bar 20 from which there extends forward a rock arm 21 that engages with the link 22. The link 22 engages a lever 23, the free end of which projects to the rear of the post 3 and is provided with a. catch rest which engages and supports a pin 31 that projects from the side of the link 12. lVhen the free end of the lever 19 is swung forward toward the front wheels of the vehicle, the engaging end of the lever 23 swings downward and releases the link 12.

In folding the carriage from open position, the lever or pedal 19 is given a kick, thereby disengaging the link 12 from the lever 23 and the handle 13 is then moved downward, thereby depressing the lever 11 which forces the rear wheels and axle upward and also drawing the front wheels upward by means of the links 18. The handle describes an arc of about 180 degrees to the position shown in Fig. 3. The rear axle is then against the bottom of the seat and the front wheel felly is against the rear axle, as shown in Fig. 4. About one-half of the rear wheel then projects up beyond the seat and below the arm. In order to afford a convenient and neat pocketfor these wheels, I have provided the covering 47 for one arm and the covering 42 for the other arm (shown This covering extends down below the side of the vehicle, as shown in Fig.

3. The wheels, as shown in the drawings, are both of the same size, but if desired, the front wheel may be made much smaller, say one-half the size of the rear wheel, for all the strain is taken by the rear wheel and axle and the front wheel is in reality nothing more than a caster wheel. If these propo r tions are observed, when the wheels are in a position, as shown in Fig. 4, both ofthe wheels willbe entirely within the pockets formedby the arms and a considerable portion of both of the front wheels will be con; cealed in the pockets, and hence a package of very small compa'ssis afforded. From Fig. 5, it will be noticed that when the rear axle 14 is swti'ng up under the seat, that it engages the latch 1? that is controlled by the sprlng 16, effectually locking the rear wheel in position. and indirectly the handle and the front wheels by reason of the connecting linkage I p When it is desired to open out the carriage, the lever edal 1'9 is iven a kick anchas seen in F igx 5, this lever also controls the latch l, thereby releasing the axle 14. By raising the handle 13, the linkage, as heretofore described, is set in motion and the wheels take their proper positions and the handle, being drawn up to its extreme upright position, automatically interlocks the pin 31 carried on the llIlk 12 with the catch rest on the lever 23, the same slldlng over the inclined bill of this lever.
