IMPROVEMENT IN SEATS FOR CHAIRS, &c.
Specification forming part of Letters Patent No. 135,973, dated February 18, 1873.
To all whom` it may concern:
Be it known that I, WILLIAM T. DonEMUs, of the city, county, and State of New York, have invented a new and useful Improvement in Seats for Chairs, &c., of which the following is a specification:
Figure 1 is a top View of my improved seat, part of one section being broken away to show the spring. Fig. 2 is a detail cross-section of the same taken through the line .r m, Fig. 1.
My invention has for its object to furnish improved seats for chairs and other articles ot' house and office furniture, which shall be strong, durable, very elastic, simple in construction, and inexpensive in manufacture, enabling the manufacturer to work up the waste pieces formed in the manufacture of other articles. The invention consists in an improved seat formed by the combination of the ring-:seat frame, the hinged sectors,'and the rubber springs with each other, as hereinafter fully described. s
- A represents the seat-frame, which is made of circular `or ring-form, and which is attached to the frame of the chair or other article. The seat is formed of six, more or less, sectors, B, the angles of which nearly meet in the center ofthe seat, and the edges of which are rounded oii. In the ring-frame A, beneath the outer part of each sector B, are formed two holes, in which are inserted the lower ends of two pins, (l, which are secured iu place byscrews, pins, glue, or other convenient means. The
upper ends of the'pins C enter elongated holes or slots in the under side of the outer parts of Y the sectors B, which sectors are pivoted to said pins by cross-pins, as shown in Fig. 2, thus hinging the said sectors to the said seatframe. If desired, the sectors B may be connected with the seat-frame A by any other kind of a hinge. D is a rubber springpsecured to the seat-frame A, alittle nearer the center of the seat than the axis of the hinge of the sector B, the sectors thus acting as levers having elastic fulcrums. The rubber springs D are kept from being pressed outward by cleats E attached to the seat-frame A, or by being let into the said frame A.
By this construction, when pressure is applied to the seat, the angles of all the sectors are pressed downward, compressing the springs D and producing a very elastic seat.
Although I have herein described the seatframe A as made in circular or ring form, I wish it to be understood that I do not limit or confine myself to such circular or ring form for the seat-frame. The said seat-frame may be varied in form, according to the requirement of the maker, without departing from my invention.
Having'thus described my invention, I claim as new and desire .to secure by Letters Pat ent- The combination, with frame A, of sectors B, provided with pivot-pins or hinges C and rubber springs D, vnear their outer ends, as and for the purpose vset forth.
