The Schedulerefened to in these Letters Patent and part of the sama.

To all whom it may concern:

VBe it known that I, OsMoRE BLNGHAM, formerly of Gardner, but now of.As burnharn, in the county of Worcester and State of-Massachusetts, have invented la new and useful Improvement; in the Application of a Seat or Cushion to the Back or Sea-t- Fame of a Ohair'; and I do hereby declare that the following, 'taken in connectionwith the drawing which accompanies and forms part of this specification, is a description -of -my invention vsuiicient to enable those skilled in the art to practice it.

In my invention I employ a web or seating stretched across the frame, and held in place by a continuous bent strip, preferably of wood, extending entirelyaround' the opening of the frame, and fastened to the frame in such manner as to firmly hold the edges of the web or seating in place, the security of the web being dependent upon the hold of this continuous bent strip'upon such edges.

lt is in a seat having a web or seating conned in place by a continuons bent strip, .that my invention primarily consists.

The invention also consists in a peculiarv method of applying this strip and the web, in such manner that the web shall cover and conceal the strip.

Figure 1 denotes a top view of the seat-frame and the web-retaining strip.

Figure 2 is a transverse section of a chair-seat ernbodying the improvement.

p A denotes the seat-frame, and

B, the web applied thereto.

The ,said seat-frame is shown as formed with a groove, c, extending around it and arranged in it, nearI its inner edge, such groove being either square or reetangular in transverse section.

' The web (which may be formed of two cloths, a. b, composing the case of a cushion, and containing between them the stufling c, of hair or other proper mater-lah) is shown as lapped at its edge around a continuous bent strip, 0of wood or other suitable material, having a section to correspond inforrnjwith that of This strip, with the edgesof the web around it, is shown as inserted and forced into the groove, the Whole being so that, when the strip is in the groove, such stripv shall be covered on all four sides by the web, the latter being preferably made to project from the strip in manner as shown in Figure 3, which exhibits, on an' enlarged scale, the groove, the strip, and a pieceof the webbing, and shows the method in which the latter sv arranged with and around the strinso as to cover it on its top surface.

seat B is not arranged so as to cover the top' surface Iof the strip C, such strip being usually held in place by nails, scriews, or cement, for, unless so fastened, a slight pull, exerted-horizontally on the web, will often serve to draw the strip and webout of the groove.

With thel specific arrangement ofthe seating, shown, in figs. 2 land 3, so as to cover lthe strip,rnot only will it be impossible to detach the strip from the groove by a horizontal strain on the webbing, exerted in the direction of the arrowf, but the strip will be covered, so as to be ont of sight, by the webbing, and thus a better nish-of the chair-seat will be made. Eurtlrermore, no nails orscrews will be absolutely required to keep the strip in place in the groove.

When the web is strained horizontally, while held by the strip in manner 'as show n in iig. 21, the tendency is to raise the 'strip'rourt ef4 the groove; but under tl-re arrangement of the web and the strip in manner as shown in fig. 3, vany tendency of a horizontal draft on the web to pull the strip out of the groove, will be counteracted or overcome by the web whichlaps over the strip, as such-will prevent the strip from heing drawn out of the groove By the employment of the -continuous bent strip as described, namely, so that it shall-,be in eon'tact'with and lretain the entire edge of the web, the web can he j readily applied .to chair-frames made more or less curvilinear in shape,and the stripwill not only secure the whole edge properly in position, but will'tend to reinforce or strengthen the frame.

I claiml. A chair-seat, havingits webvor seating secured to the frame by a continuous bent web-retaining stri-p or splint.

y 12. The strip G'andweb B, so arranged and applied to the groove e that the web covers and conceals the strip, substantially as shown and described.
