SPECIFICATION amal am-1'; of Letters Patent No..252,431, dated January 17, 1882.

i Application filed June 8, 1881. ("No model.)

To all whom it may concern:

' Be it known that I, CLAUDIUS O. (JoLLtGNoN,

of Harrington township, in thecounty of Beror used as a carriage, with thearms on one side' broken away. Fig. 3 shows an intermediate position with the arms on one side broken away, and Fig. 4 shows it folded for packing.

My invention relates to that class of chairs known as childrens high chairs}? which are adapted to be converted into childrens carriages.

The object of my improvement is to adapt one of said class of chairs to be either convert ed into a childs carriage or invalids chair,

or to be folded up in compact form for stowage or for transportation; also, to provide certain improvements in the details'of construction,

as hereinafter fully described.

- In a convertible chair constructed in accord ance with my invention, AA indicate the front legs, .which are extended upward to constitute the sides B B of thebhair-back. The back of this chaircan be made of any usual or desired construction, it being, however, preferably provided with the handle 0, connected with the back by means of rods, so as to serve as a means for propelling and guiding the carnage when the chair is converted into such device.

. DD indicate the chair-arms, which are secured to the sides of the back and extended down to form braces D D, that are rigidly connected with the frontllegs. The front legs are supported by wheels E, the axle of which has its bearings in the said legs, at points sufficiently near the lower ends thereof to raise the sameabove thofloor. -Tl1e braces Dare connected by a round, F, which not'only strengthens the structure,but' which also subserves another importantfunction, which will appearin the description farther on of the conversion of the chair into a childs carriage.

G G indicate the hind legs otlthe chair. These legs are providedwitdi an upper round and with a lower round, b, the former carrying.

a spring-hook, H, which, when the structure is arranged to form achilds high chair, as shown inFig. is to be engaged with a round, b of the front legs, ,so as to'p'revent the two pairs of legsfroln spreading apart. The hind legs are supported bygwheels G Gr,'in a'inanner similar to that in which the front legs are supported, and they are'provided in 'their outer sidestwith the longitudinal grooves I I, which receive pins 1', secured on the inner sides of the front legs.

K indicates the seat, which is pivoted at its rear end between the extensions B of the front legs. The front board, L, is hinged to theunder side of the front part of the seat, and the footboard L is hinged to the frontboard by means of'the hinges I, in such manner that when the front board is dropped, as shown in Fig. 1, the rear edge of the foot-board will rest squarely against the same and the said footboardassume a.horizontal, or approximately horizontal,position. The nature ofthese hinges I, however, which consist of bent rods. at the sides of the boards,enables the foot-board to be folded up closely against the front board.

M M indicate metal braces, which connect the seat with the hihd legs, and which coustitute an important feature in this invention.

.These braces are pivoted at their'upper ends t0,,the underside ofthe seat-frame at points adjacent to its front bar, while their lower ends are pivoted to the inner sides of the hind legs vance of the center, which will bethcir pivotal points on the hind legs. The hind legs maybe formed with notches in their front edges near their upper ends and below the points at which the braces are pivoted. These notches may be adapted to receive the round F, which connects the brace-bars or downward extensions of the chair-arms, and subserve their purpose w hen the chair is converted into a carriage,

as will appear farther on.

As seen in Fig. l, the structure is converted into a chair, the spring-hook H engaging round I) to prevent the legs from spreading, and the forward portion of the seat resting upon the top ends of the hind legs, whereby the seat is supported in a horizontal position.

To convert the chair into a carriage it will only be necessary to disengage the said springhook, and placing the foot on the lower round of the rear legs, in order to steady the device, pull back on the chair-back, whereby the legs will spread apart, the rear legs shifting backward and the front legs forward until the hind legs rest upon the round F, and the braces M are swung back of the center, as shown in Fig. 2, thereby holding together the chair, which, it will be seen, consists essentially of two parts, one the front legs, the back, the seat, and its appendages, and the other the hind legs. In, this position the chair-back will be inclined rearwardly to constitute the back of the carriage, the pins on the front legs remaining at thenpper ends of the grooves in the hind legs, and the front hoard, L, .resting upon the top ends of the hind legs,which said ends, being moved forward in proportion to the aforesaid backward movement of their lower portions, come into place to form supports for the hinged front board, and to maintain the same firmly. The foot-board will be elevatel, as shown, and the forward portion of the seat will rest upon studs P, tl at are secured to the inner sides of the arm extensions or braces D.

In folding up the chair 'into compact form,

n for transportation, raiseit to its fullest height' from the position shown in Fig. 1. Then, by

. preference, tilt it over forward, so that the wheels of the front legs will alone rest on the v my own invention I aflix my signature in presfloor.-' Then lower the same, and in so doing the foot-board will fold upon the front board paral el with the braces D, and bynow pushing on the back of the chair the wheels resting on the floor will move the required distance, so that the pins on thefront legs will move to secure a third or intermediate position between thehighest and lowest positions, as seen in Fig. 3, by providing the round F with a hook,f, which engages with an eye or staple, 9 in the bottom of the front board and holds the chair in this position, the seat resting upon the braces.

M, which are thenperpendicular.

Having thus described my invention, what I claim, and desir to secure by Letters Patent, 18-- 1. The folding chair adapted to be converted into a childs carriage or rolling chair, and consisting essentiallyoftwo parts, one embracing the front legs, back,arms, hinged seat, and front and foot boards, and the other consisting of the hind legs, formed with grooves receiving pins on the front legs, and connected with the seat by pivoted braces, substantially as described. v

2. The combination, in a folding chair convertibleinto a-childs carriage or rolling chair, of the front legs extended to form the sides ofthe back, with the arms D, extended down to'constitute braces D, secured to the front legs, the round F, connecting the said braces,

the hind legs formed with groovesreceiving pins on the front legs, and the metal braces M,

pivoted to the hinged seat and to thehind legs, substantially as described.

In testimony that I claim the foregoing as once of two witnesses.
