NURSERY-CHAIR.

CLREGEl-IQATIQN forming part of Letters Patent No. 313,881,dated March 17, 1885.

(No model.)

To all wh am it may concern:

Be it known that LBENJAMIN O. ODELL, of Kingston, Ulster county, State of New York, have invented a new and useful Improvement in Convertible Chairs; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying sheet of drawings, making part of this specification.

This invention is in the nature of an improvement in convertible chairs; and the invention consists in a convertible chair with one pair of legs hinged to the under side of the rear of the seat-frame, with a second pair of legs pivoted to said hinged legs, and with a push-handle pivoted thereon, which pushhandle is united to the back of the chair by pivoted levers, as is more particularly described hereinafter.

In the accompanying sheet of drawings, Figure 1 is a front elevation of my chair in its high position; Fig. 2, a side elevation of same; Fig. 3, a side elevation of chair lowered; Fig. 4, a side elevation showing the operation of ratchet-bar.

Similar letters of reference indicate like parts in the several figures.

This invention relates moreparticularly to the Well-known high chair and carriage; and it is designed to facilitate the conversion of the chair from ahigh chair to a carriage, and vice versa, with the utmost facility. To that end I construct my chair with crossed legs, A and B, the legs A being hinged to the rear under side of the seat-frame O and pivoted to the legs B, as at a. To the legs B is pivoted a push-handle, D, and to this push-handle are pivoted two levers, E, these levers being also pivoted or hinged to the lower part of the back of the chair F. To the back Fis also fixed an adjustable catch, 2), and to the push-handle D is fixed apin, c, to engage with the said catch.

To the legs B are secured wheels G, and to the legs A a wheel, H.

The chair is provided with the ordinary play-table, I, and with a foot-rest, K.

Now, to convert a chair constructed sub stantially as above described into a trundle, as shown in Fig. 3, it is simply necessary to disengage the catch 1) from the pin 0 and pull outward the push-handle D, when the legs A and B will turn on the pivot a, and the levers E will turn on their pivots on the push-handle D and on the back of the chair F, permitting the legs A and B to spread apart and the seatframe to rest upon the upper surface of the legs B, bringing the wheels G and H in contact with the floor, in which position the chair may be wheeled as a carriage from place to place.

To elevate the chair to a high position, it is simply necessary to bear down slightly on the push-handle D, and lift upward the back F of the chair, when the legs will be brought more or less together until they rest on their lower ends, and the push-handle D will lie snugly against and parallel with the back posts of the back F of the chair, the levers E fitting parallel to and within the sides of the pushhandle D, as shown in Figs. 1 and 2, the pin 0 engaging with the catch b, keeping the push handle D in this upright position, and as long as the push-handle is in this way secured the chair is rigidly held in its highest position, as shown in Figs. 1 and 2.

The operation of the levers E is such that not only is the push-handle kept rigidly in its proper position by them when the chair is lowered, but they at the same time direct the pushing force on the handle immediately to the heaviest part of the chair when it is occupied-viz., the seat; and when the chair is being lowered from its highest position they assist in preventing its too rapid descent.

To the unhinged legs B of the chair is hinged a ratchet-bar, L, which bar passes through a staple, d, fixed to the side of the push-handle D. The operation of this ratchet-bar, in connection with the levers E, is such that the height of the chair can be varied so as to adapt it as a table-chair to the wants of children of different ages, for by simply disengaging one of the ratchets from the staple the chair may be raised or lowered, and held in a given position by the engagement of any given ratchet.

To the back of the chair, by means of a bolt, is secured a standard, M, for a sunshade. The lower part of this standard is constructed with a slot, 6, so that the parasol can be raised and lowered to the extent of the length of the slot, and can be turned to the right or left, a setscrew holding it fixed in any given position; or the parasol may, when desired, be entirely removed from the chair. Links at connect the upper part of the rear leg to the seat 0. These are not absolutely'necessary for the support of the chair when elevated, but they serve to prevent the front end of the chair from rising in the adjustment of it from an elevated to a low position, or the reverse.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination, in a convertible chair, of the seat-frame, pivoted cross-legs, a pushhandle pivoted to one pair of said legs, the links which unite the push-handle to the back of the chair, and a loekingdevice for the pushhandle, substantially as described.

2. The combination, in a convertible chair, of a suitable seat-fran1e and crossed supportvsubstantiall y as described.

ing-legs pivoted to the chair, of a push-handle pivoted to one pair of legs, and provided with a clasp, d, pivoted levers secured thereto and connecting said handle to the chair, and a ratchet-bar, substantially as described.

3. The combination, in a convertible chair, of a suitable seat-frame, crossed and pivoted legs, a push-handle pivoted to the rear legs, and a pivoted lever connecting the handle to the chair, whereby the seat-frame is adapted to rest upon the edge of one pair of said pivoted legs when the chair is in its lowest position,
