NURSERY-CHAIR.

SPECIFICATION forming part of Letters Patent No. 231,689, dated August 31, 1880.

Application sled Maren 31, leso. (No model.)

To all whom it may concern:

Be it known that I, Asnnn B. STEVENS, of Stapleton, county of Richmond, State of New York, have invented an Improvement in Chairs', of which t-he following description, in connection with the accompanying drawings, is a specification.

This invention relates to an improved childs chair and carriage; and it consists, essentially,

To in combining with the pivoted or turning parts of the front legs certain springs, whereby, whenthe said front legs are turned back to lower the seat and make the chair into a carriage, the parts of the chair located above the parts of the front legs then in horizontal position are spring-supported.

I have herein shown the pivot ofthe movable part of the front legs as a rod extended through elongated slots in the short or stitf zo parts ot' the front legs attached to the seat. This rod is connected with the front springs attached to the seat, which springs are sufficiently stron g to keep the rod at the lower ends of the said slots when'the pivoted parts of the front legs are turned back, which insures supporting the seat at front on the said springs. The side pieces, which, when the seat is elevated, keep together the front and rear legs, are slotted at their front ends to surround a 3o rod extended across the pivoted front legs near their lower ends, and between this rod and ears, upon the side pieces, are interposed springs, as hereinafter described, which, when the pivoted front legs are in horizontal posi- 3 5 tion, also act to support the rear part ot the seat.

Figure l represents, in side elevation, a combined high chair and carriage containing my invention, one of the wheels being broken 4o away to show the construction of the upper end of the pivoted front leg. Fig. 2 shows a Vertical section of my chair converted into a carriage having its seat supported entirely upon springs. Fig. 3 is a rear elevation of the chair used as a carriage, one ofthe rounds being broken awa-y to show the seat-fastening device 5 and Fig. 4 is a modication.

The seat a oi' the chair and the back and side arms may be of any usual construction.

5o At the front of the seat are rigid short legs b, provided near their lowerends with elon-` gated slotsc, through which is extended the rod or round d, the ends of which outside of the said short legs enter holes or recesses in each ofthe pivoted front legs, c, the said rod serving as the pivotal point for the said pivoted front legs. The rod dis embraced by the lower ends of the forward sprin gs, f, connected at their upper ends with the seat c. These springs are made of considerable strength, and 6o their normal tendency is to keep the rod el in the lower part of the slots c, as shown in Fig. 2, so that weight being applied to the seat will permit the rod d to risc and fall in the said slot as the springs f, one at each side the seat, are more or less compressed.

When the seat is in elevated position it is not desired to have the seat spring or yield; so I have provided each short leg b witha stop, g, to be acted upon by the curved or notched 7o upper ends, h, ot' the pivoted legs e. (See Fig. l.)

When the chair is usedfor a high chair the round i, at the upper ends of the rear legs, Z, is held between a pin, 7c, on the seat and a locking device, j, (shown as a longitudinally-` movable bolt,) having a nger-piece, 2, eX- tended through a slotted plate, 3, the said plate guiding the bolt and limiting its range of motion.

The front and back legs are held separated at the proper distance by means of a braceframe composed of two side pieces, m, joined by a round, n. The front ends of these side pieces,m, are slotted, (see Fig. 2,) and through 8 5 the said slots extends the rod p, the ends of which are fixed in the pivoted front legs, e. Upon each of these side pieces, m, are ears r, that receive rods s, having holes at their opposite ends, to be entered by the rod p. (See 9o Fig. 3.)

`In Fig. 2 that part of the rod s which embraces the rod p is broken away to show one of the slots o in one oi' the side pieces, m. Spiral springs t are interposed between the ears r and the heads or enlarged parts of the rods s. When the seat is lowered the pivoted front legs are turned into horizontal position, and the side pieces are turned up at the sides of the seat c near itsrear, as in Fig. 2. In roo this position (see Fig. 2) the seat is locked upon the round n, as before described, for the round u and the rear part of the seat will be supported on the springs t, the rod p playing up and down in the slot 0, according` to the Weight on the seat and the jar to which the carriage is subjected.

At the upper and lower ends of the pivoted front legs are loose wheels w wz. On each side piece is a stud, a2, and at the lower end of each back leg, l, at its inner side, is an open notch, b2. (Shown in dotted lines, Fig. l. Each back leg, Z, is connected with each side of the seat by means of a link, c2.

When the high chair is to be converted into a carriage the pivoted front legs are turned back under the seat horizontally, and in such condition the springs j' and t are brought into condition to be effectual in supporting the seat. The back legs, during this operation of converting the chair into a carriage, have their ends elevated behind and upon the back of the seat, such movement acting to turn the side pieces almost into a vertical position, so that its round u can be locked by thc locking devicej, and then the tops of the back legs are turned far enough back, away from the back of the seat, to cause the notches at the lower ends o il the said legs to embrace the stops a2 of the side pieces, after which the said legs become serviceable as a handle by which to push the carriage, the round t being grasped by hand.

In this application I do not broadly claim the pivoted front legs provided at each end with wheels and the side pieces and back legs, as they are shown in another application for United States Letters Pat-'ent filed by me complete October 1, 1879. In that application l show a link to connect the short rigid parts of the front legs with one of the side pieces or braces, as I therein termed them 5 butin this application the links are connected with lthe seat and with the outer sides oi' the back legs; and I am thus enabled to make the said links co-operate with the back legs near their lower ends, to give additional support to the seat, and also to hold the upper round, z', of the back legs up snugly against the lower side of the seat, which enables me to employ a simple bolt to fall behind the said round to lock the chair in elevated position, whereas in the other application I was obliged to employ a hooked springfasten-ing.

Instead of mounting the wheels w upon studs or bearings connected with the front legs, c, I may mount them directly upon the rod d, next the inner sides of the short portions b, and between such portions and the adjacent springs, and in such modication the rod d will be extended entirely through the front legs, e, and will be headed, or otherwise held in place, to retain the legs c from separating. This modification is shown in Fig. 4. Instead of making the slot c directly in the wood ot' the portion b, I may attach to the said portion a metal loop, leaving between it and the portion b a slot.

I claim- 1. In a combined high chair and carriage, the pivoted front legs provided with wheels, the connected side pieces, the back legs pivoted to the side pieces, the seat a, the links connected with the seat and with the back legs, and the fastening or locking device, combined and to operate all substantially as described.

2. In a combined high chair and carriage, the portions I), attached to the front of the seat land slotted as described, the pivoted frontlegs and wheels w, the rod d, and the springs between the said rod and seat, substantially as described.

3. In a combined high chair and carriage, the seat, portions b, connected therewith, the front legs, c, and wheels w @02, the rods d 17, connected with the said pivoted legs, the side pieces, andthe springs at front and rear of the seat, between the said rods and seat, to support the seat in a yielding manner only when the legs c are turned backward to form a carriage, substantially as and for the purpose described. l

4.. In a combined chair and carriage, the pivoted front legs and the rod p, combined with the side pieces slotted at one end to surround the said rod, the ears on the side pieces, and the springs interposed between the said ears and rod to permit the rod to move in the slots 0 when the legs c are turned back under the seat and the side pieces elevated, substantially as and for the purpose described.

5. The seat and its portions b, slotted at c, as described, and provided with stops g, the rod d, placed in the said slots and serving as the pivot for the front legs, the springs to connect the said rod and seat,'and the frontlegs notched at their upper ends, as described, the said notches engaging the stops on the said portions b, when the seat is elevated, to support it in an unyielding manner, substantially as-described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
