CUSHION Fon GAR-SEATS.

SPECIFICATION forming part of Letters Patent No, 778,218, dated December 27, 1904:.

Application led April 11,1904. Serial No. 202,524.

To all whom it may oon/cern,.-

Be it known that I. EDWARD Cr. BUDD, of the city and countyof Philadelphia, State of Pennsylvania, have invented an Improvement in Cushions for Car-Seats, ofwhich the following is a specification.

My invention has reference to cushions for car-seats;` and it consists of certain improvements which are fully set forth in the following specification and shown in the accompanying drawings, which form a part thereof.

The object of my invention is to provide a construction for cushion-frame adapted to both seat and back which shall be composed largely of metal and be substantially flreproof.

My invention is especially adapted for use .in the railway-car seats, where the danger to loss of life from lire is very great in case of collision. l

In carrying out my invention I employ an outer or boX frame of metal, preferably i-shaped in cross-section and bent into the requisite rectangular form,and combine therewith sheet-metal bands arched over the top from side to side, coil-springs under said steel bands, transverse metallic slats or crossbars supporting said springs and united at their ends to the side portions of the outer frame by rivets, and a covering of woven ratan or other upholstery, the free edges of which are folded under the outer frame and held in place by hook-shaped metal clips which are secured to the upholstery and engage the inner edge of the lower iiange of the boxshaped frame.

My improvements also comprehend details of construction which ,together with the abovementioned structures,- will be better understood by reference to the drawings, in whiclr- Figure 1 is an inverted plan view of vmy improved seat with a portion of the slats and springs broken away to show the interior. Fig. 2 is a cross-section of same on line AA; and Fig. 3 is a perspective view of one of the clips in act of clamping upholstery to the frame, the latter being shown in section.

The box-frame is rectangular and made of sheet metal of substantially i: shape in crosssection, thel outer wall a having the top flange o and bottom flange a2. The free 'edges of these flanges may be curved, folded, or beaded, as shown at c, which adds greatly to the strength. The two longest sides of the boxframe have their upper outer surfaces depressed,l as o3, to receive the ,ends of the springs and rivets 7). box-frame of one continuous strip of sheet metal, with the parts o and a2 cutso as to form miter-joints at the corners.

` represents flat springs arched over the upper or outer surface of the box-frame, and are seated at their ends upon the opposite side rails and riveted at b', as before stated. These spring-plates are preferably provided upon their under sides with a central strip b2 of greater strength, and to both of which plates the coil-springs d are bolted. The lower ends I prefer to make the f of these springs are supported upon transn verse bars or slats e, formed of stamped sheetsteel and ribbed, as at e', for rigidity.l These ribs terminate a short distance vfrom each end of the slats, and said ends are' bent down to form feet e2 to rest against the under surface of the flange@2 of the box-frame and secured in place by prongs f on the feet, which eX- tend through holes in the iiange ft2-and bent over or riveted, as shown in Fig. 2. In practice I prefer to have the spring-plates tl come close together,so as to form only a small space between them to insure the structure being more fireproof.

Above the spring-plates is placed the upholstery, and ordinarily this consists of a sheet Y of canvas o and a covering of woven ratan o or other outer material. This upholstery may be of any other construction preferred and may be made iireproof in any of thewellknown ways. The upholstery is pulled down over the box-frame and folded under the bottomkliange a2 and held in place by ,the metal clips lo, which are of the shape shown, having wide portions z', provided with teeth or prongs m, which are driven through the upholstery and clenched down, and hooked portions n of less width, which hook over or engage the beaded edge of the lower flange a2 of the box metal frame. These clips preferably abut, as shown, so as to form a continuous metal covering over the upholstery on the bottom of the scat. In practice I prefer to apply the clips to the upholstery before it is placed on the seat-frame, and to insure easy application I soak the upholstery to cause it to expand, and after being applied in place and the clips hooked to the edge of the flange a2 the drying of the upholstery causes it to shrink and make the covering tight. This is especially the case with an upholstery of canvas and ratan. The clips may be secured to the upholstery in any other suitable manner, if so desired, as, broadly considered, it is immaterial to my invention how the attachment may be made.

From the foregoing description it will be seen that the cushion is essentially lireproof and at the same time both light and strong. It is also easily and quickly assembled, and consequently cheapto manufacture.

Matter shown but not claimed in this application forms subject matter of another pending application, Serial No. 186,609, filed December 26, 1903.

Vlfhile I prefer the construction herein shown and described, I do not confine myself to the details, as these maybe modified without departing from the spirit of the invention.

IIavingnow described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a seat-cushion, the combination of a box frame of sheet metal having bottom lianges, cross-slats or' metal having their ends secured to the bottom flange of the box-frame, coil-springs resting upon the slats, sheet-metal springs resting upon the coiled springs and having their ends secured to the sides of the box-frame, upholstery stretched over the sheet-metal springs and extended down and under the lower lange of the box-frame, and metal clips secured to the upholstery and hooked over the inner edges of the lower llange of the box-frame for securing the upholstery to the under side of the box-trame.

2. In a seat-cushion, the combination of a box frame, springs supported by the boxframe, upholstery stretched over the springs and extended down and under upon the lower part of the box-frame, and metal clips secured to the upholstery and hooked to the under side of the box-frame.

3. In a seat-cushion, the combination of a box frame of sheet metal having bottom anges, cross-slats carried by the box-frame,

coil-springs resting upon the slats, sheet-metal springs resting upon the coiled springs and having their ends secured to the sides ol the box frame, upholstery stretched over the sheet-metal springs and extended down and under upon the lower flange of the box-traine, and a series of metal clips secured to the upholstery and hooked over the lower llange olt the box-frame and substantially abutted to form a substantially continuous metal covering for the upholstery on the bottom oi the box-frame.

et. A seat-cushion for cars consisting ol a box-frame of sheet metal having alower lange, upholstery extending over the box-frami and under the lower flange, springs for supporting the upholstery, and means'lfor securing the upholstery to the box-trame consisting ol a series of metal clips secured to the upholstery and hooked over the edge of the flange oi the box-frame.

5. A seat-cushion for cars consisting ol .a box-frame of sheet metal having a lower llange, upholstery extending over thebox-lrame and under the lower flange, springs Vlor supporting the upholstery, and means for securing the upholstery to the box-frame consisting of a series of metal clips having prongs by which they are secured to the upholstery and having hooked portions which are hooked over the edge of the llange of the box-frame.

6. Means 'for securing the upholstery to a. box-frame of a cushion consisting ol a sheetmetal clip having one edge made wide and provided with a series of prongs arranged in alinement for attachment to the upholstery and the other edge made narrow and bent into a hook to form an open jaw lor attachment to the frame or' the cushion.

7. In a seat-cushion, the combination ol a box-frame, springs supported thereby, upholstery stretched over the springs and boxframe and having its edges 'folded under the said box-frame, and a series of metal plates secured to the upholstery near its edge and also attached to the box-frame imlepeiidently of the upholstery, whereby the upholstery is stretched over and held lo the box-frame without being directly fastened thereto.

In testimony of which invention ,l hereunto set my hand.

EDWARD (fir. BUDI).
