CHILDVS NURSERY-CHAIR.

SPECIFICATION forming part of Letters Patent No. 236,273, dated January 4, 1881. Application filed April 11, 1880. (No model.)

To all whom it may concern:

Be it known that I, ASHER B. STEVENS, of Stapleton, county of Richmond, State of New York, have invented an Improvement in Childrens Ghairs,of which the following description,

in connection with the accompanying drawin gs, is a specification.

This invention relates to an improvement in childrens convertible chairs, and is an im- IO provement upon-United States Patent No.

207,621, September 3, 1878, granted G. M. Patten.

The object of my invention is to make a chair of that class more durable and simple. 1 In that patent the front legs, at each side of the chair-seaahave fastening devices to hold them in upright position and the chair-seat elevated; but the rear legs, pivoted at the level of the seat, were not provided with mechanism to lock them in position.

In this my invention I have dispensed with the hinges and fastening devices for the front legs, and have pivoted the upper ends of the back legs to the back above the level of the 2 5 seat, thereby enabling the backlegs to extend farther above the level of the seat than in the patented chair, so as to form a longer trundling-handle when the seat is lowered for a carriage. I have provided the seat at its 0 under side with a strong locking device, to engage a. pin or projection on an upper crossround of the rear legs, to lock the said rear legs both when the chair is used as a high chair and when the said legs are reversed and employed as a trundling-handle for the carriage. This locking device takes the place of the two lockin g devices heretofore employed on the front legs, and makes the chair stronger and more easy to manipulate. I have also 40 connected the table and foot-board by means ofa connecting-link or lockin g device, to hold them rigidly together at certain times, as hereinafter described.

Figure 1 represents,in side elevation, one of 5 my improved chairs with the seat elevated, the

table thrown forward, and the foot-board connected with it by a connecting device. In this figure one of the rear legs and its connectinglinks are partially broken away to show the fastening device for the rear legs. Fig. 2 is a side elevation, partly in section, showing the rear legs reversed, thus lowering the seat for a carriage. Fig. 3 is a rear elevation of Fig. 2. Fig. .4 is an enlarged detail of the fastening or locking device. I

The seat A, the front legs, B, the rear legs, B, the braces G, the small rollers D, and the large wheels G are substantiallyas in the patent referred to. Instead of pivoting the upper ends of the rear legs at the level of the seat, as in the said patent, I have pivoted them to the back F at the point a, so that the f.

"said rear legs, when inverted as in Figs. 2 and 3, will assume a more elevated position at the rearof the seat, thus placing the round 0 higher from the ground or floor, to avoid stooping when the chair is being rolled as a carriage. Upon the cross-round 01. near the pivoted ends of the rear legs, I have placed a pin or other suitable projection, e, which is engaged by the locking devicef when the seat is elevated, as in Fig. 1, while the other end, 6, of the said pin is engaged by the said lockin g devicef when the rear legs are elevated, as in Fig. 2, the said locking device positively 7 holding the said rear legs in each of its two positions, no other locking device being required. This locking devicefis shown as a piece of spring metal having one of its ends connected with the seat at 9, its other end bent and slotted to embrace a headed pin or screw, h, which guides the locking device as it is made to rise and fall, as it does when being disengaged from or being engaged with the pin referred to. A spiral spring, 1', throws the 8 5 said lockin g device down. The lockin g device has two openings, 2 3, to engage the pin 6 6 The axis or stud lc of each large wheel 0 is supported at points each side of the said wheel by means'ot links at a. The link on is pivoted to the seat at 4, and the link a is pivoted to the rear legs at 5, the link at resting at the rear of the wheel, while the link a passes across the front of the wheel, and is connected with the stud or pin 70 at the outside of the wheel. This construction prevents the wheel from being broken, and also securely retains it upon the pin or stud against any liability of accidental removal, and also forms a strong support for the said pin or stud.

The table 0, pivoted to the arms of the seat, is as in other chairs, except that it has attached to it the connecting device 1), (shown as a hook adapted to engage an eye, q, connected with the foot-board r.) The pivoted arms 8 of the foot-board are prevented from rising beyond a certain distance by means of stops t. When the connecting device 12 and foot-board are brought together the table is locked, so that it cannot be raised by the child, and the seat A and the foot-board is also held up. When the foot-board is elevated in this way and the table locked to it, it becomes more diflicult for the child to fall from the seat.

It is obvious that a pin on the locking device might enter a hole in the round d, this being an equivalent for the construction hereinbefore described.

The short seat-legs 1), upon which the front legs, B, are pivoted, are as in the patented chair referred to.

I claim-- 1. In a childs chair, the seat, short seatlegs I), pivoted front legs, and links to connect them with the rear legs, combined with rear legs made reversible and pivoted to the chair-back above the seat, substantially as and for the purpose described.

2. In a childs chair, the seat, the short legs, the pivoted front and rear legs, and their connecting-links, combined with the round carried by the reversible rear legs, and a locking device, substantially such as described, adapted to engage the said round in both positions of the rear legs, to hold them locked in place, substantially as described.

3. In a childs chair, a table, 0, connected with the seat-arms and the foot-board, combined with a connecting or locking device, to hold the table and foot-board rigidly in position with relation to each other, substantially as described.

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

ASHER B. STEVENS.
