IMPROVEMENT IN CHILDRENS CHAlRS.

Specification forming part of Letters Patent No. 220.258, dated October 7, 1879 5 application tiled April 16, 1879.

To all whom it may concern:

Be it known that I, AsHER B. STEVENS, of Philadelphia, county of Philadelphia, State of Pennsylvania, have invented an Improvement in Ghildrens Chairs, of which the following description, in .connection with the accompanying drawings, is a specification.

This invention relates to improvements in childrens chairs.

In this my improved chair the seat is made vertically movable with relation to a permanently-upright base, which may or may not be provided with rollers or wheels on iXed axles, and the seat is so connected with the base that it may occupy'a position at the top of the base, or within and below its top, an independent frame supporting the back portion of the seat when said seatis arranged at the top of the base. This independent frame also serves at times for a handle for the carriage and as rockers.

Figure l represents my invention arranged as a high chair on wheels. Fig. 2 shows the seat carried downvfor a low chair or carriage, this figure also showing, in dotted lines, the handle portion turned into a position it may occupy in order to convert the low chair into a rocker; Fig. 3, a rear elevation of Fig. 2; Fig. 4., a top view; Fig. 5, a detail, representing the inner side of one of the back legs of the base; and Fig. 6, a modification.

The rigidly-connected base A has each ot' its sides composed of side legs, a b, shown as joined together by the tie c and round d but, if desired, the legs of this base may be variously modied-as, for instance, the leg b may be bent and connected directly with the top of leg a. These side portions or legs of the base may be joined by suitable rounds or stretchers.

The chair-seat B, having any usual or proper side arms and back, has at its front, near each corner, a rigid seat-leg, e, which is j oined with a link, j', pivoted at its other or lower end upon the leg a at 12, the said seat-leg e and link forming a toggle-jointed connection between the seat and base A. These seat-legs e also serve to support the foot-rest g.

At the rear of the base, and as herein shown, I have, by means of links h, pivoted the lower end of an independent frame, C, composed, preferably, of two curved wooden bars, z', which serve a threefold purpose, viz: First, as a movable rear support for the seat; second, as a handle for the low chair or carriage, and third, as rockers for the chair.

At the rear of the legs b are fastening devicesj, shown as provided with lugs 2, to prevent the lower ends of the frame O next the links h from moving outwardly while the frame C is in its most upright position, to serve as a support for the rear of the chair-seat at a distance above the top of the legs of the base, the pins 4t on bars i then resting in slots 5, or guides (see Fig. 5) at the inner sides of the legs b, the rear end of the seat then resting upon the round G between the bars i, a seatholding projection, 7, fitting over or engaging the said round, as in Fig. 1.

At the rear of legs b are hooks 3, which, when the seat is carried down, as in Fig. 2, permit the frame G to be turned back, the pin et then being held by the hooks 3, leaving the frame in suitable position to serve as a handle for the low chair orcarriage. This frame C has its bars i curved, so as to serve the purpose of rockers when desired, the said frame being adapted to be turned to a position at the under side of the base, as shown in dotted lines, Fig. 2, the ear pieces or hooks 8 on the bars 11 then hooking over or engaging a connecting-round between the legs, or engaging other portions of the base, while the pins 4 rest against the inner but lower edges of the legs b.

`At the upper ends of each pair of legs are stops 9 10. The one 9 serves as a back-stop for the link f when the seat is as in position for a high chair, as in Fig. 1, and at the same time the stop l0 serves to arrest the frame O, to prevent it moving farther toward the center of the chair.

The table l is made in two parts, connected together at or near its center by a fastening device, m, and each half is hinged to tableholding links u, pivoted at o, each link having a slot or equivalent suitable to engage a headed screw or projection, p, attached to the arm b2. This table, when separated at its center, may be turned on the hinges r each side thev side arms, and, if desired, the links n may he disengaged from projections p, and be turned downward tothe rear of the chair, and be then again connected together Or not, as in dotted lines, Fig. 1.

The lower ends of the legs a b of the buse are shown asprovided with wheels s t, by which to supportthe base and pei-init it to be rolled as a carriage.

Instead Of the linksfto connect seat-legs e with the legs a of the base, I may groove the inner sides of the legs as shown in the detail, Fig. 6, a pin on each seat-leg e entering this groove, and resting in the short portions 13 thereof when the seat is most elevated ordepressed.

I claim- 1. In a convertible high and low chair or carriage, the combination of a rigid upright base, a Yertieallydnoving chair-seat, and a frame, (l, pivoted to the base, and serving convertibly as a seat-support or trundlin g-handie, substantially as described.

2. The base A, a vertically-moving chairi seat, B, scat-legs e, linksf, and stops l) 10, in combination with the frame C, serving as a seatsupport Or a trundling-handle, substantially as shown and described.

3. The combination, with a convertible chair, of a frame, C, constructed substantially as shown, and adapted to serve as a SeatsuppOrt, a trnndling-handle, and rockers, substantially as specified.

4. The base and frame C, having curved side arms, i, combined with devices, substantially as described, to hold the said frame in position with relation to the base to support the seat for a high chair, or to extend back Ot' it and serve the purposes of a handle, as and for the purpose set forth.

5. The combination Of the chair-seat, the separable table hinged to supporting-links, and the supporting-links pivoted tothe chair-arms, whereby said table may be swung to the sides and rear ofthe seat, substantially as described.

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

ASHER B. STEVENS.
