EDWARD G. BUDD, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO HALE AND KILBURN MANUFACTURING COMPANY, A CORPORATION OF PENNSYLVANIA.

CUSHION FOR CAR-SEATS.

SPECIFICATION forming part of Letters Patent No. 782,823, dated February 21, 1905.

Application filed December 26, 1903. Serial No. 186,609.

T all whom, it may concern.

Be it known that I, EDWARD Gr. BUDD, of the city and county of Philadelphia, State of Pennsylvania, have invented an Improvement in Cushions for Car-Seats, of which 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 metallic and fireproof.

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

In carrying out my invention I employ an outer or box frame of metal, preferably I: in cross-section and bent into the requisite shape, and combine therewith sheetsteel bands arched over the top from side to side, coilsprings under said steel bands, and transverse metallic slats or cross-bars supporting said springs and united at their ends to the side portions of the outer frame.

My invention also includes in such a structure a covering of woven ratan or other upholstery, the free edges of which are folded under the outer frame and united thereto by eyelets or other suitable fastening devices and preferably shielded at its edges by metallic strips which impart both protection and finish.

My invention further embodies a fireproof covering for the under side of the cushion to prevent flames passing upward to the interior and destroying the more combustible portions of the upholstery.

In addition to the above-mentioned features my improvements comprehend many details of construction which, together with said above-mentioned structures, will be better understood by reference to the drawings, in which Figure l is an inverted plan view of my improved seat with a portion of the fireproof bottom-covering brokenaway to show the interior. Fig. 2 is a cross-section of same on line A A. Fig. Sis a cross-section of same on line B B. Fig. 4 is a cross-section of same on line C C. Fig. 5 is an inverted plan view of the box-frame structure. Fig. 6 is a crosssection of same on line D D. Fig. 7 is a perspective view of the end of one of the cross bars or slats.' Fig. 8 is an inverted plan view of a seat embodying a modified form of my invention. Fig. 9 is a cross-section of same on line E E, and Fig. 10 is a perspective view of one corner of the box-frame.

The box-frame is rectangular and made of rolled sheet metal of substantial in cross-section, the outer wall (0, having the top flange a and bottom flange (K. The free edges of these flanges may be curved, folded, or beaded, as shown at a, which adds greatly to the strength. The two longest sides of the box-frame have their upper outer surfaces depressed, as a to receive the ends of the springs b and rivets b. I prefer to make the box-frame of one continuous strip of sheet metal, with the parts a and a cut so as to form miter-joints at the corners, as shown in Fig. 5. These miterjoints may be reinforced by angle-plates Z, riv= eted in place. The parts a of the strip are overlapped and riveted, as at a, Fig. 5, to complete the continuity of the frame. The under surfaces of the corners, as at m, are depressed, as are also the ends of the parts (4 upon two opposite bars of the frame, as at these depressions being to permit the upholstery to be folded upon itself without projecting beyond the remaining surface.

b'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 72 of greater strength, and to both of which plates the coil-springs (Z are bolted. The lower ends of these springs are supported upon transverse bars or slats e, formed of stamped sheetsteel and ribbed, as at e, for rigidity. These ribs do not extend to the ends of the slats, but l to the details, as these may be modified \vith instead terminate a short distance from each end, and said ends are bent downward, as at a to form feet which rest against the inuersurface of the flange (1. of the box-frame, Figs. 2 and 4. This flange is perforated, as at r, and through these perforations the extensions f g are passed and the extensions f bent over to lock the slats in place. This leaves the pointed prongs g projecting for purposes described later on. The lower ends of the springs (Z fit into holes in the slats (Z, as at and the coils may be further secured by the staples (Z' clenched over thenn'as shown in Fig. 2.

In practice I prefer to have the spring-plates bcome close together, so as to form only a small space between them to insure the structure being more fireproof. Above the springplates is placed the upholstery, and ordinarily this consists of a sheet of canvas 0 and a covering of woven ratan 0 or other outer material. This upholstery may be of any other construction preferred and maybe made fireproof in any of the well-known ways. The upholstery is pulled down over the box-frame and folded on the corners into the recesses or depressed portions p and also folded under the bottom flange (b and pushed upon the prongs g of the slats. It is thus held in po sition, and over it projecting strips [L are placed and held down by bending over or clenching said prongs g, as shown in Fig. L. The strips h, the upholstery, and the flange c are further fastened together by eyelets '27, as shown in Fig. 2, the eyelets passing through holes in the several parts. The holes in the flange a are shown in Fig. 5 at 2,. The upholstery is folded over at the corners on the bottom or back of the box-frame, and where they overlap they are received in the depressed portions m to prevent uneven under surfaces.

To make the cushion more fireproof against flames from below, I may use a back-covering of asbestos of any suitable form, as indicated at w. This backing also acts to keep out dust.

In place of the manner of securing the slats to the box-frame described above they may be secured as shown in Figs. 8 and 9. In this case the ends of the slats are extended over the outside of the flanges a and bolted in place by bolts l; upon the upholstery. The free edges of the upholstery may be shielded by the metal strip and held in position by the eyelets, as before, passing through the plate and flange of the box-frame.

While I have found eyelets excellently adapted as a means for securing the upholstery in place, it is evident that it may be secured in any well-known manner, such as stitching or welting, &c.

From the foregoing description it will be seen that the cushion is essentially fireproof and at the same time both light and strong.

While I prefer the construction herein 5 shown and described, I do not confine myself out departingfrom the spirit of the invention.

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