FOLDING'CARRIAGE.

SPECIFICATION forming part of Letters Patent No. 598,964, dated February 15, 1898.

Application filed May 1,1897. Serial N5. 634,756. (No model.) i

To all whom it may concern: Be it known that we, ADOLF STERN NATHAN LEFKOWi'rZ, citizens of the United States, residing at New York, in the county and State of New York, have invented certain new and useful Improvements in Folding Oarriages; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable'others skilled in the art to which it appert'ains to make and use the same. Y

Our invention relates to improvements in vehicles, and particularly to improvements in a folding baby-carriage.

The main object of theinvention is to produce a childs carriage which may be folded into a small compass, whereby it may be stored when not in use without requiring much space, thereby making it of particular advantage for residents in apartment houses and the like where commodious quarters are lacking.

The invention consists in a device arranged to accomplish the above object and which will first be described in connection with the accompanying drawings and then pointed out in the claims. I

In the drawings, Figure 1,is a longitudinal sectional view of a-carriage embodying our invention in its extended position; Fig. 2, a plan. of the same with the bottom partly broken away; Figs. 3,4, and 5, detail views illustrating the axle; Fig. 6, a plan view showing the wheels folded over; Fig. 7, a longitudinal section of the same; Fig. 8, a similar view showing the parts partly folded; Fig. 9, a transverse section on the line 9 9, Fig. 6; Fig. 10, a longitudinalsection, on an enlarged scale, of the carriage completely folded; Fig; 11, a perspective view showing the appearance of the whole device when folded, and

Figs. 12 and 13 detail views referred to hereinafter.

Referring to the drawings, A and A are are hinged flaps A which are capable of being folded either inward, as shown in Fig. 8, or outward, asshown in Fig. 1, being locked and shown in Fig. 2.

to the sidepanels A when in the former position by means of any suitable fastening device or devices -as, for instance, the hooks the flaps A these trays thus coming together to form a case or box, the two trays being held together by any desirable fastening de'- vice, such as the look a, Fig. 11.

Each panel B B is provided at its outer end and on each-side with slots 1), which slots are also extended into the end strips B B", as Through these slots pass bolts 0, projecting fromfolding springs 0-, these springs being formed of four pieces 0' c 0 0' hinged together at 0 as best shown in' Fig. 13, and each capable of being extended to form the three sides of a rectangle, being retained in the extended position by a suitable extension device, such as a rod'C, passed through the upper and lower arms 0 c and provided with spring-catches c", which 0, each rod also having a head 0 to limit its downward movement.

prevent the accidental withdrawal of the rod To the inward-extending ends of the lower ortions o of each air of s rin s an axle P a:

and wheels are attached, the axles being each I constructed of anouter shell and an inner flexible or jointed axle proper.' The said .flexible or jointed axle proper is made in two parts, each having one inflexible end'extend-' ing beyond the shell and provided with a thimble-skein on which the wheel is mounted,

ed as to slide longitudinally in the shell, whereby it may be drawn outward to a certain extent in order that the wheels may be folded over with their spokes approximately parallel to the shell. Furthermore, when the inner end of each part being so constructdrawn inward the parts of 1 the flexible axle may be clamped or secured in such a manner that they cannot be accidentally drawn out.

The specific construction of the axle illustrated in the drawings is as follows:

D is a tube forming an outer shell which is slotted at cl, within which tube is located a flexible axle proper composed of two parts D, (best shown in Figs. 3 to 5,) each consisting, preferably, of four parts d d d (:1 three of which are hinged together in any ordinary way, as shown at d while the outer joint 01 next to the wheel is provided not only with a hinge, but also with a clamp or look device, whereby the inflexible outer end d of each axle part may be secured rigidly to the next adjacent portion d of the axle part or may be unlocked therefrom, so as to be turned at an angle thereto. This joint, as shown in Fig. 5, is formed by providing the portion (1 at its inner end with a tongue d which enters a slot in the end of the portion (2 being pivoted to the said portion (1 by a pin (i passing through it and through the tongue. In the inner end of the tongue 01 is formed a notch or opening arranged to receive one end of abolt'd", located in a recess in the end of the portion d yieldingly pressed outward by a spring c1 and capable of being retracted by a finger-piece d, which projects outward through a slot in the side of the portion d The flexible axle parts are each surrounded by a spring 61 located within the outer shell D and bearing against a collar c1 fixed on the inner end of the flexible part and provided with a bolt extending outward through the slot cl, upon which bolt is placed a nut c1 whereby the flexible axle part may be forced outward and then clamped or clamped when drawn inward by the spring 01 Each end of the shell D is provided with a cap d, having a square opening through which its respective axle part projects, said axle part being preferably square in cross-section and fitting snugly in the openingin order that the axle part will be held against any tendency to rotate which might be caused by friction between the wheef and its thimble-skein.

The wheels E are of any desired construction and held on the thimble-skeins in the usual manner.

In packing the carriage the rods 0 are withdrawn by pressing the springs 0 against the respective rods and pulling the rods upward. The parts 0 c of the springs are then pressed toward the center of the vehicle, thereby permitting the axles to come up close against the under side of the panels B B, the bolts 0 being loosened and pushed toward the center of the carriage, whereby the axles are brought beneath the middle of said panels. The nuts (Z are then loosened and forced outward, the two flexible or jointed axle parts being thereby extended as far as the slots cl will permit, whereupon the nuts d are tight ened to prevent the springs from forcing the flexible axle parts inward again. The bolts in the joint (1 are withdrawn and the thimbleskeins turned at an angle to the shell D, after which the flexible axle parts may be bent over so as to bring the wheels flat on top of the panels B B, so that when the bottom is folded up into the case formed by the two dashboards and their attached parts said wheels will be next to the said dashboards, while the axle-shells D will be in the space between the two panels B B.

The axles are held at a predetermined distance apart by means of a folding or telescopic reach, which is preferably constructed of two parts D each provided atone end with a collarencircling the center of its respective axleshell D, while at the inner ends each part D is provided with a loop encircling the main portion of the opposite part D By this construct-ion the two parts of the reach may be slid together when the carriage is being collapsed, and in order to permit the reach, when thus closed or telescoped, to be folded with the folding of the buggy-bottom the parts D are each jointed at d, the joints being each made similar to the joint at d in the flexible axle part above described, with the exception that no bolt is employed-that is to say, one of the parts of the reach has a tongue fitting into a slot in the other part, a pivot-pin serving to hold the tongue in place. In order to hold the reach in its extended position, a series of cotters or pins (1 are employed. This construction will be clear from Fig. 12.

The carriage sides F are made flexible or collapsible, being either of cloth, leather, or the like, or of a construction which will permit them to be folded for storage within the case. In Fig. 1 is shown the latter construction, each side F preferably consisting of two parts which meet at the center and are fastened together in any suitable way, as by the latches f. These sides are made of a number of bars pivoted together in the form of a lazytongs and are provided with hooks f, which engage rings f secured to the inside of the side panels A By this construction the sides may be unhooked from the dashboards and unlocked from each other and then collapsed and packed into the spaces between the panels B B and the dashboards A A.

The seat for the carriage comprises two parts G G, hinged together, so as to fold toward each other when not in use, each part being suitablyv upholstered in any desired manner and preferably provided with springs to give elasticity to the cushions. The bottom G of the seat is provided with short legs g, which serve to raisethe said seat a short distance above the carriage-bottom. In Fig. 1 we have shown two of such seats, though, as is obvious, only one may be employed.

A folding parasol H may also be provided, in which case the dashboards are supplied with theusual parasol-holding devices or sockets h,

To the outer face of each dashboard is secured a handle I, jointed at 2', so that it may be turned down at an angle to the back of the dashboard, whereby the carriage may be pushed from either end, and at the same time the handles may be turned up vertically to permit them to be grasped in carrying the case, as shown in Fig. 11.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is Y 1. In a folding vehicle, the combination, with a bottom, of springs connected to the bottom and capable of movement toward and from the center of said body, and means for holding said springs at the desired distances apart.

2. In a folding vehicle, the combination with a bottom,of collapsible springs connected to said bottom, and axles carried by said folding springs.

3. In a folding vehicle, the combination with abottom,of collapsible springsconnected to said bottom and capable of movement toward and from each other.

4:. In a folding vehicle, the combination with a folding bottom, of axles connected to the bottom and capableof movement toward each other, and a telescopic reach connected to both axles, each section of the reach being jointed.

5. In an axle for foldingvehicles, the combination with a shell,-of a flexible axle composed of two parts mounted in said shell and capable of movement longitudinally therein, and means for retaining said axle parts within said shell.

6. In an axle for folding vehicles, the com-' bination with a shell, of a flexible axle composed of two parts mounted in said shell and capable of movement longitudinally therein,

' a slot in the bottom, axles secured to the other ends of the springs, and a collapsible reach secured to the axles. W

9. In a folding vehicle, the combination,

with dashboards, of a collapsible bottom, collapsible springs secured'thereto, each spring comprising two parallel parts, and a hinged.

part, a removable brace through the parallelled parts, axles at the ends 0fv the springs and a collapsible reach secured to the axles.

10. In a collapsible vehicle, the combination, with a bottom, of axles connected therewith, a collapsible reach connecting the axles,

,each section of the reach being jointed, and

pins for holding the reach in its extended position.

In testimony whereof we affix our signatures in presence of two witnesses.
