AUGUSTUS ELIAERS, OF-BOSTON, MASSACHUSETTS.

SEAT FOR PUBLIC BUILDINGS.

Specification of Letters Patent No. 11,991, dated November 28, 1854.

To all whom ii /may concern:

Be it known that I, AUGUSTUS ELIAERS, of

Boston, in the county of Suffolk and State of Massachusetts, have invented certain-new and useful Improvements in Chairs or Seats for Public Buildings, &c., and that the following description, taken in connection with the accompanying drawings, hereinafter referred to, forms a full and exact specification of the same, wherein I have set forth the nature and principles of my said improvements, by which my invention may be distinguished from others of a similar class, together with such parts as I claim and desire to have secured to me by Letters Patent.

The figures of the accompanying plate of drawings represent my improvements. Figure' 1 is a front elevation of the chair, representing the seat in a vertical position. Fig. 2 is a vertical transverse section of the same. Fig. 3 is a front elevation, with the seat'in a horizontal position. Fig. 4 is a central transverse vertical section of the same. Fig. 5 is a longitudinal vertical section of the arm-rest &c., taken in the plane of the line C, D, Fig. 3. Fig. 6 is a transverse vertical section of the same, taken in the plane of the line A, B., Fig. 4. Fig. 7 is a view of a portion'of the lower framework of the back of the chain.

My improvements are made upon a chair, for which I have previously applied for Letters Patent, of the United States, and consist in bringing the back into a vertical or upright position, by the falling of the tilting seat,the rear edge of the seat, while dropping, traveling against curved arms, attached to the framework of the back, or forming an extension of the same. By this means the back is retracted, when relieved from the weight of the occupant, by the tilting of the weighted seat, and without the aid of springs.

I have also made an improvement in the manner of upholstering the chair, the cushions to the back, seat, and arm rests, being formed on panels of wood, and then inserted in the metallic framework of the chair, this metallic framework being constructed with a shoulder, against which the panels bear, and to which they are fastened. By this arrangement, the necessity for using gimp, or a binding for the cloth is avoided, the outer surface of the shoulder of the framework, serving as a finish to the edge of the cloth.

a, a, a, in the drawings represents the side framework of the chair.

.7), b, are, the arm-rests.

c, c, is the seat, hung upon a pivot 12, in

the side framework, and back of the center of the said seat, the rearedge of which is loaded, so as to cause it to drop when not occupied, and bring the seat into an upright position.

e, e, is the framework of the back, turning upon a pivot at f.; To this framework are attached two curved arms, or extensions, g, 9*, extending below the seat, which are so curved as to form the arc of a circle, concentric with the circle described, by the rear edge of the tilting seat 0, c. The back is connected to the arm rest-s, by the rods It, h, which travel, when the back is moved forward or back, in the hollow spaces 2', z', the back being sustained by a shoulder is, on each rod 2', as will readily be understood, by inspection of Figs. 4:, and 5. A shoulder is formed in the rear edge of the seat, 0, a, which abuts against the curved arms 9, g.

From this description it will be seen, that when the occupant rises from, or leaves the chair, the seat and back, will be simultaneously brought intoan upright position, the rear edge of the seat or shoulder of the same, traveling against the curved arms 9, g, and thus, as the back turns on a pivot at f, bringing the back into an upright position.

The framework of the seat, arm rests, back, &c. is made of iron or other suitable metal, with the exception of the top and bottom of the back, which may be made of wood, as iron would prove uncomfortable to rest against.

The cushions of the back, and seat, are formed on panels of wood, Z, Z,m, m, the cloth or covering of the cushions being simply lapped and glued over the edges of the wood. The panels rest against shoulders n, 0, formed in the metallic frames, 6 ep p, of the back, and seat, respectively as shown more particularly in Figs. 1 and 4 and are fastened to the said frames by screws 9, g, &c. By this arrangement, the cushions are held in place in a. very simple manner, and the coverings fastened without the aid of gimp or binding, the outer edge of the shoulder of the metallic frames, servwood, and thus dispense with covering those portions with cloth. The cushions of the arm rests, are formed on pieces of wood, and fastened to the metallic framework a, a, in a similar manner.

Having thus described my improvements, I shall state my claims as follows-I shall not and do not claim to have invented the device of tilting the seat by means of weights or other mechanical equivalents, because of recent investigations I have found this to be quite an old device. It is found in the mechanical arrangement for operating the tilting leaf of the French writing desk, which when not in use is in a vertical position making a part oft-he entire plain front of the desk or secretary, and when inuse it is in a horizontal position for the support of the writing materials and the arms of the writer, its lnner edge abutting against arail,

in the vertical part of the secretary in the same manner as the seat rests against the under side of'the back of my chair. And this desk leaf is balanced or hung with weights and tilted by them in a manner which is very generally understood. For this reason I' especially disclaim the tilting of the seat by means of weights&c. but,

What I claim as my invention, and desire to have secured to me by Letters Patent is I claim actuating the back by the drop ping of the tilting seat, so as to bring it into an upright position, by means of the curved arms, attached to," or forming'a part of, the frame-work of the back, and acted upon by the rear edge of the seat, or a shoulder in the same, as above set forth.
