man Patent No. 93,815, daad August 17, 1869.
o IMPnovnMnNcr IN SPRING cnsHIoNs.
The Schedule referred to in these Letters Patent and making part of the lune.
To dll whom it may concern Be it'known vthat I, CHESTER D. FLYNT, of the ,city of Philadelphia, and State of Pennsylvania, have invented a new and useful Spring-Cushion Seat, or support; and yI do yhereby declare that the follow- -ing is a full and exact description thereof', reference being had to the accompanying drawings, and to ,the let-ters of reference` marked thereon.,
The nat-ure of ,my invention consists of an interwoven fabric of cushion form, made' of steel strips, combined with a supporting-flame, to'which the ends -of the strips are secured.
'.lheinvention is adapted to carriages, railwaywars,
chairs, 8vo., forming seats of great elasticity and strength,
vof this specification- Figure l .is a plan of the improved cushion, as adapted to railway-car' seats.
Figure 2 is a transverse section' through the middle of the same. v
Figure 3 is a like section of a chair-seat, showing a variation in the mode of attaching the ends of the The'frame a, to which the woven fabric is secured,
41 prefer making in the flanged form,to secure strength with; lightness. l
The upper edges of the frame are rounded, as shown, to prevent their cutting or breaking the steel fabric, hereinafter described.
There are cross-pieces, b c, for the support of other parts. l o i lhe cushion part is formed of steel strips d, whichare secured at each end to the vertical outside edges of th'e frame a, by means of nails through holes of fthe strips, and at about one inch und a halt' from theupper edges of the frame, or as lnear the bottomthereof as may be prncticable,in preserving the proper degree of strength to that part ofthe frame.
lhe object in attaching the strips so ,low down on the edges'of the frame, is to secure as much elasticity4 as possible, and, lalso, to makethe fastening more comis'borne down upon the rounded edges of the same.
The strips ll are of such length, that when they are interwoven, as represented, to form a net-work, and
their 'end secured to the frame a,the proper couvexity ticity and strength.
To give greater security to the fastening of the strips d, I fasten steel or other metallic strips, e, upon them, at or near their point of attachment to the frame in the same and into the frame a. l
The interwoven steel fabric, as described, has great elasticity and4 strength, but I impart additional elasticity and strength to it by interposing' between it and the crosspieces b c, a series of conical or Vspiral springs, f. There being a space between thewoven vsteel vfabricand the rounded edges ofthe frame a, asshown in the drawings,"greater elasticity is'secured than if the tened to the frame, and there is less strain upon the strips when the cushion is presseddown.`
The steel fabric maybe -covered with canvas, and that with athin layer of cotton, hair, wool, or other 'fibrous material, in the 'usual manner, and then the outside covering be secured, as in other seating.
In the construction' of seats fol" chairs, it may be desirable` sometimes to give the snpporting-frame a the form represented in tig. 3, the upperinuer edge vof the rounded, as shown. A
The strips d, when interwoven,are drawn tight, and their ends securedby nails in the grooves fm, In this give the proper convexity to the seat. What I claim-as new, and desire to secure by Letters Patent, i'sas described. e
