Specification of Letters Patent.

Patented Jan. 30, 1906.

Application flied may 2v. 1904. serai No. 210,035.

To (1n/l whom it may concern: r

Be it known that I, HENRY S. HALE, of the city and county of Philadelphia, State of Pennsylvania, have invented an Irn rovenwnt in Seat-Cushions, of which the ollowing is a specification.

My invention has reference to seat-cushions; and it consists of certain improvements which are fully set forth in the following specification and shown in the accom anying drawings, which `form a part thereo The obj ect of my invention is to provide a convenient and inexpensive means for securing theupholstery upon sheet-metal boxl'rames of seat-cushions.

ln carrying out my invention I provide thc seat with'a box-frame having lower llanges grooved on their under sides and combincd with clamping -strips fitting said grooves and adapted to clamp the edges of the upholstery tightly in the grooves, said clamping-strips eing drawn tightly into place by a series of clamping-bolts.

My invention also consists in other details of construction which, to ether with the features above specified, wil be better understood by reference to the drawings, inwhich-f Figure 1 is a perspective view of a seatcushion of the characterembodying my invention. Fig. 2 is a cross-section of a ortion of same on line 2 2 of Fig. 3, and Flg. 3 is an inverted plan view of one corner of the seat-cushion.

A is a box-frame made of sheet metal, having the upper flanges B and lower flanges C, the latter having the grooves J and the beaded edges C. This box-frame is preferably made of sheet metal formed into the i shape shown,l

D represents sprin -plates secured at their ends to the sides o the box-frame A at d and sustained upon coil-s rings E, which latter rest upon cross s ats F, preferably formed of sheet metal. rIhe u holstery G extends over the springlates E and boxframe and the edges are irought under the lower flange C, ,as shown.

H represents clamping-strips and fit the grooves J ,being of less cross-section than the cross-section of said grooves. These clamping-strips'are preferably made of channeliron, having the depressed or recessed portion h. The side edgesare also perferably p inclined, as shown, so as not to give too sharp a bend to the upholstery at g, where itis lclamped in the grooves J b v the clampingstrips H. 'Ihe edges of the upholstery are thus protected and not liable to fray, and the strips H act as strong portions to sustain all heavy wear and tear.

I re resents clamping-bolts and extend throug the clam ing-strips, upholstery, and

o ut departing from the spirit of the invention.

Having now described my invention, whatV I claim as new, and desire to secure by Letters Patent, is-' l. In a seat-cushion, the combination of a sheet-metal box-frame having a lower flange beaded at its inner edge and having its under part provided with an upwardly-extending groove parallel to the beaded edge forming a recess on the under part and an upward extending rib upon the upper part of sa1d flan @transverse supports for the springs exten ino over the beaded edge and resting upon the upwardly-extending rib of the boxframe, springs sustained by `said supports,

upholstery extending' over the springs and box -frame and having its ed e extending over the groove on the-under si e of the boxframe, a clamping-strip for clamping the upholstery into the groove, and clamping-bolts for drawing the strip into the grooves upon the upholstery. l

2. In a seat-cushionVthe combination of a box-frame having a lower flange formed with.

an upwardly-extending groove spring de vices supported by the box-frame,oupholstery extending over the spring devices and box-frame vand having4 its edges extending over the under surface of the lower flange of the box-frame, clamping-strips for clamping the ul holstery into the grooves, clampingbolts 'or drawing said strips into the grooves upon the upholstery, and sustaining crossslats for the spring structure having their AIO() ends extended over the lower flanges of the grooves, upholstery extending over the spring devices and box-frame and having its edges extendin over the under surface o the lower flange o the boX- frame, clampingstrips formed of channelbars with the grooved portion extending downward awa from the upholstery for clamping the upho story in the grooves, .and clamping-bolts for clamping the channel-bars upon the upholstery extending through the lower flange of the box-frame and having their heads shielded by the grooves of the channel-bars.

4. In a seat-cushion, the combination of a box-frame having a lower flange formed with an upwardly-extending roove on the bottom an upwardly-exten 'ng rib above the groove on the top and a beaded edge, spring devices supported by the box-frame upon the beaded edge and rib and secured to the lower flange, upholstery eXtendin over the spring devices and box-frame and aving its edges extending over the under surface of the lower flange of the box-frame, clamping.-

strips formed of channel -bars With the grooved portion extending downward away from the uphblstery for clamping the upholstery into the grooves, and clamping-bolts for drawing said strips into the grooves of the liange of the box-frame and upon the upholstery said bolts having their heads shielded in the grooves of the channel-shaped clamping-strips.

5. In a seat-cushion, the sheet-metal boxframe having upper flanges B and lower anges C the latter being provided with grooves J and beaded edges C', in combinanation with clamping-strips H of considerably less cross-section than the cross-section of the grooves, clamping-bolts extending through the clamping-strips and the lower flanges at positions corresponding to the grooves, cross-slats F resting upon the beaded edges of the lower flanges and clamped in position, springssupported upon the crossslats, spring-plates sustained by the springs and secured at their ends to the box-frame, and `upholstery extending over the springs and box-frame and having its edges clamped between the grooved portions of the lower flanges of the box-frame and the clampingp ates.

In testimony of which invention I hereunto set my hand.
