Application filed January 24,1883. (N o modeL) To all whom it may concern! 1% it known that I, EDWARD .H. Bo GiANo, a citizen of the United'States, and a resident of the city and countyof Camden, and State of New Jersey, have invented a new and useful Improvement in Convertible Chairs, of which the following is aspecification.

The objects of my invention are to furnish an inexpensive, strong, and'substantial chair, which may be converted at will from a high to a low chair, a commode-chair, a chariot-chair,

a stationary chair, or a perfect cradle orrocking-crib.

In the accompanying drawings, forming part of this specification, and in which similar letlers of reference indicate like parts throughout the several views, Figure 1 represents a side view of my invention as a stationary-chair; Fig. 2, a fi ont viewof the same; Fig. 3, my invention as a rolling-chair; Fig. 4, a. front view of the upperrocker and its arms; Fig 5, a front view of the lower rocker; Fig 6, a front view of the movable wheels and their arms; Fig. 7 a top view of the table, and Fig 8 a perspective view of the seat of the chair.

The side of my chair-frame consists of a truss formed of the diagonal struts B C and verticaland horizontal braces A X, mortised one into the other, and combines the greatest strength with the least weight of material, and the frame, so far asforward and backward rack is concerned, is not liable to get loose or shake in any of its parts, and is, in fact, absolutely indestructible except by a crushing force sufficient to break the material of which the frame is composed. The diagonal struts B, which form the rear'legs of the chair, are furnished with wheels D, which are permanently fixed to the struts, and which, when the chair is in a vertical position, always rest upon the ground. The front'of the chair is supported upon the diagonal struts 0 when the chair is intended for a stationary chair; but if it be desired to change it into a chariotchair or. coach, thearms E (one end of each of whichis pivoted to the diagonals G and the other furnished with wheels D) are lowered, as shown in Fig. 3, and suitably secured. The distance from the center of the pin upon which the arms E are pivoted to the outside of the wheel D being greater than the distance from this pivot. to the bottomof the strut O, the front of the chair is elevated and rests upon the wheel D, and the chair may be rolled to any desired place. To strengthen the arms E they are connected together by a brace, F. If a chair has rollers on all four feet and permanently fixed to. these feet, it'is liable at all times to be pushed about by children and to be the cause of considerable trouble and annoyance. If it hasarms carrying adjustable rollers on all its four feet, it requires some of the rollers td be put down every time it is desired to move it; and if the rollers are attached to legs at right angles to each and hinged to the seat of the chair, the device is very unsteady and unsatisfactory; but if a chair is construct ed as mine is, with the rollers fixed on the rear legs it has every facility of locomotion and pos ion Withtlie front rollers up, the chair stands in a position'so that it cannot be moved by children, but is readily moved by a grown person by canting it back on its rear feet and running it as a barrow, the trussed frame ren-.

dering this perfectly safe. When the front rollers are put down, it becomes a chariot-chair, easily moved by anybody.

The seat and back of the chair are hinged together, and are so uredtothe frame by means of hooks and staples, and may either be situated near the top of the frame, forming a high chair, or they may be placed lower down, forming a low chair. The seat is provided with a rest for the feet I, and has a li ,-K,,andorifice L, which may be furnished with a chamber, when desired, for commode use.

The chair-may also be furnished with a table, M, which rests upon cleats N, and is secured with a bolt, 0.

The back of the chair is furnished with rockers P 1?, the lower one being a stationary fixture, and the upper one being carried upon arms R, which are pivoted to the diagonals G. The upper rocker may be used as a handle, by means of which the chair may be pushed when being used for a coach.

When it is desired to use the chair for a oradle, the upper rocker is drawn out, as shown in Fig. 3, and the seat is moved to its lowest position, also shown in Fig. 3 The chair is now laid on its back and furnished With a mattress, and forms a perfect cradle or rockingcrib.

' Having thus described my invention, I claim 5 and desire to secure by Letters Patent- 1. The hereindescribed chair-frame, consisting of the upright posts A, horizontal braces X, and diagonals B C, said posts and braces being mortised'into said diagonals, and

I0 said diagonals extending beyond the vertical plane of said posts and forming the legs and feet of the chair, substantially asand for the purposes described.

2. The hereindescribed convertible high I 5 and low child s chair, having its seat and frame furnished with hooks and staples for attach- EDWARD H. BOLGIANO.
