` 10 all whom t 77mg/ concern.'

Be it known that I, XVILLIAMAM- CAvA- NAUGH, a citizen ot the United, States. and a resident of the borough ot' Richmond, .Richmond County, State of N ew York, have in` vented certain new and useful improvel ments in Chair Seats, ing .is a specification. Kp v My invention 'relates to an iniprovement in seats for chairs, and particularly to leather seats, one of the `objects oli the invention being the provision o'li' a chair seat in which ilexing' and bending of the leather in the manufacture and application ot the seat have been eliminated.

A further object of the invention is the provision of aunitary leather chair seat structure which is adapted to be applied to a chair with ease and facility.

A still further object of `my invention is the provision of a chair seat of leather in which a nailing or securing strip is provided ot' which the follow'- which is adapted to be secured directly tok the chair, this strip being,` independently attached as by sewing for example to the main port-ion or body ot the chair seat, means also being provided whereby the tacks or other devices employed tor holding the seat in place are concealed. A

A further object of the invention is the provision ot reinforcing material adapted to he attached to the leather of the seat and to take some of vthe strain when the seat is iu use.

I am aware that chair seats have heretotore been constructed oi leather but the usual practice .is t-o apply a comparatively thin piece of leather to a wooden frame, the leather being ot' the trame and secured to the frame in any convenient manner.v Such. an arrangement, however, is not satistactoryfor several reasons. in Vthe lirst place turning` the leather down around the edges of the frame causes the leather to very soon wear through or to craolr,.wl'lile in the second place the leather, in order that it may be folded or turned down around the edges ol.E the frame, must be so thin that it soon wea-rs out.

In my arrangement, a very heavy leather may be employed, sole leather being pre` 4:terred and no turning of the leather down around the edge of a frame 1s,necessary at all. ln factin my improved `structure the seat 1s a unitary affair and no extra frames or other appurtenances are necessary at all.

turned down around the edgesV Inthe accompanyingdrawings-f Figure l 4illustrates my `improved vchair seat applied 'to a chair, part of the seat being broken away to illustrate itsy construcf tion; ,l

2 'is a bottom ofFig. l; and A i Figs. 3 and 4 are similar views otinodilied constructions.

- yReferring to Fig y `l and 2, l designates a chair to which my -improved chair seat may be applied." The chair is provided with the usual seat opening` 2 cut away as indicated to provide a ledge 3 on which the chair seat is to rest and by which it is to be supported.

' The chair seat comprises a piece of leather,preferably a. good grade of sole leather,v designated 4L cut to conform in shape to the opening' 2 but small enough so that when in position an annular space designated 5 will beleft all around the seat or body of the seat and the chair.

Sewn or otherwise attached to the under side of the body portion 4f is a comparatively narrow strip 6, wide enough to not only rest upon the ledge 8, but projects some dista-nce beyond vthe edge of the ledge so as to extend some distance beyond the edge ot the body portion of the seat. This strip may be made in sections it' desired and provides -a flange all around the edge of the body 4. Interposed between the b ody portion et and thesecuring strip or strips 6 is a reinforcing strip or layer 7 ot canvas, wire mesh or other suitable material thisreintorcing materialfbeing preferably vcemented to the body portion 4; throughout its entire surface.

The seat is secured `in position by nailing, for example, through the securing strip or strips 6 after which a sectional :filler strip `is cemented or otherwise secured in the spaces 5 between the edges ol the Y body portion 4 and the frame ot' the chair,

this strip lying Hush with the uppersurtace of thel body il.

It will be seen that this construction pro` vides a very neat and compact structure with the .means for securing the seat in place entirely hidden, the usualbending ot the leather about a frame,v in tact the usual frame, being dispensed with entirely.

My improved structure also provides a comfortable all leather seat which-will last almostl indefinitely owing to the fact that the same can be 4constructed of heavy sole leather it desired, Athe reinforcing material.

plan view et the scat between the top ylos or strip 7 preventing permanent sag or depression of the body portion 4 so that the neatk appearance of the 'seat is indefinitely preserved.

In the modified form of construction illus` trated in Fig. 3 I have provided a chair seat similar to that already described, the canvas or fabric reinforcing strip 7 of Fig. 1 having been, replaced by interlaced thin metal strips 9, and narrow strips 9 of fabric or webbing While in Fig. 4 I have used a Woven cane reinforcing structure designatedlO.

Having particularly described my inven,`

Vtion in what I claim and desire tosecureby Letters Patent is:

'1. A chair seat comprising a flat leather body portion, al flat leather securing strip secured to the under side of the body por- Z tion and extending beyond the edges thereof U '2. A chair seat comprising a leather body portion, a securing strip secured to the unvder Side of the body portion and extending beyondthe edge thereof to provide an annula'r flange extending around the edge of the body portion, reinforcing material interposed between the securing strip and` the body portion of the seatand secured to both of them, and a concealing strip overlying said flange and lying Hush with the top surface of the body portion.

This specification signed this 15th day of October, 1923. .A
