SPECIFICATION forming-.part of Letters Patent No. 283,405, dated August 21, 1883.

Application filed December 11,1882.

To @ZZ whom 15 may concern.-

Be it known that I, Josera W. KENNA, a citizen oi' the United States, residing at Chicago, in the county of Cook and Stat-e of Illinois, have invented certain new and useful Improvements in Nurseryhairs, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, in lwhich.- Y

Figure l represents a view in vertical section. Fig. 2 is a transverse sectional view of the table and arms detached. Fig. 3 is a view in front elevation, and Fig. 4 is a side view showing the extensions or standards folded upv to form a low wheeled chair in accordance with my invention. tion, with standards extended to form a high chair. Fig. 6 is a detail view of the springcatoh used to hold the standards in upright position.

The object of my presentinvention is to provide a childs high chair that can be readily converted into a low wheeled chair or car riage, and which shall be so simple anddurable in its construction, that it may be easily operated, and will sustain the severe usage to which this class of furniture is constantly subjected.

A further object of my invention is to fur- Dish improved means of attaching the footrest and table to the chair. y

To this end my invention consists in the several combinations and arrangements of parts,

hereinafter described, illustrated in the acoonr panying drawings, and particularly dened in lthe claims at the end of this specification.

the end of the opposite arm, c', and catch into its notch a* when the table is swung to a position in front of the chair.

To the lower portion of the front legs, B, are pivotally attached, as shown,'the front standards or extensions, B", by means of the rod b,

which passes through the legs and standards.

Fig. 5 is a view in rear eleva- (No model.)

These two front standards, B', are also held togeth er by the rounds b", and are furnished near.

.their ends with the eyes b2, from which extend thelinlzsEto similar eyes, ci, on the rear standards or extensions, C. These standards C', braced by the rounds c and c5, are connected to the rear legs, C, in a manner free to swing, by the rod c, which passes through the standards and through oblong slots near the bottoms of Atherear legs, C, in which, above and bearing against the rod c, are seated the spiral springs c. The rear standards, C', are, as shown, considerably longer than the standards B', and bear upon their ends the wheels F, on which the chair rests when converted into a low chair or carriage. The baci; round, el, preferably iiattened and curved outward, carries the bent spring-latch G2, having a perforation, c, into y which catches the pin ci, projecting from the To the inner adapted to lock in the grooves or slots cu in the standards C when the parts are arranged to i'orm a high chair.

From the foregoing construction, it will be seen that when it is desired to forni a high chair the standards B and C are brought into substantial alignmentV with the legs Band C,

and are securely'ih eld in this position by means of thespring-latch C?. A It will be noticed that by reason or' the pins cg entering the grooves c? the springs at the bottoms of the rear legs are thrown out of action, as otherwise they might permit the chair to tip backward too far. In converting the high chair into a low chair or carriage, the spring-latch C is depressed, and the front and'rear standards are swung forward until they assume a position at right angles to the legs, when the round b will enter the socket ai oi' the spring-latch A2, attached to the under side of the table D, and will seourelylocl: the parts. In this position the chair is sustained by the four wheels F, I

and can be easily rolled from place to place. A slight spring action is given to the chair by means of the spiral springs om, and, if desired, springs may be applied in a similar manner to the bottoms of the front legs. It will thus be seen that the position of the parts can be easily and quickly changed to form a IOO high chair or ylow-wheeled chair or carriage,l

as desired, and these parts are so simple and so securely connected together as to resist the severest usage to which they are likely to be subjected. A

The foot-rest G is attached to the chair in the following manner: To the under side of this foot-rest are attached two brackets, g, having slotted sockets g', in which are seated the spiral springs y2, and through the lower portions of which passes the rod b. A rod, g3, is connected to the back of the .foot-rest, and slides in the eye g4 on the round g5 of the front legs of the chair.

Although I have thus stated what I regard as the best embodiment of my improvements, it is obvious that extensive modifications or ,variations of the same may be made without departing from the spirit of the invention. Thus, for example, the wheels may, in some instances, begomitted, and by curving the rear standards in a direction reverse of that shown `a low rocking-chair Vmay be formed.

' back standards,- and not in combination with the front and rear standards in both positions, as hereinbefore set forth. Again. convertible chairs having front or back supporting-legs to which one set of pivoted extensions were attached, the otherl set of cxtensionsbeing hinged to the chair-seat, are old in the art; but when Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is i l. The combination, with the front and rear supporting-legs of the chair, of the extensions or standards pivoted thereto, and the links which pivotally join the opposite front and rear kstandards together, substantially as described.

2. The-combination, with the front and rear supporting-legs of the chair, of the extensions or standards pivoted thereto, and the links which pivotally join opposite front and rear standards together, said rear standards being longer than the front, substantially as described.

3. The combination, with the front and rear supporting-legs oi" the chair, of the extensions or standards pivoted thereto, andy the links which pivotally join opposite front and rear standards together, aid rear standards being provided with wheels, substantially as set forth.

e. The combination, with the front and rear supporting-legs of the chair, of the extensions or standards pivoted thereto, the links which pivotallyjoin opposite front and rear standards together, and the catches to hold said standards in either closed or extended position, substantially as described. Y

5. The combination, with the front supporting-legs and with the recessed and slotted rear supporting-legs of the chair, of the extensions or standards pivoted thereto by cross-rods, the links which pivotally join opposite front and rear standards together, and the recoil-springs seated within the recesses of the rear legs, substantially as described.

In testimony whereof I have hereunto set my hand this 9th day of December, A. I). 1882.
