To (LZZ whom it may concern:

Be it known that I, EDWARD G. Brno, a citizen ofthe United States,residing at Philadelphia, 1n the county of Philadelphia and State of Pennsylvania, have invented a cer tam new and useful Improvement in Seating, of which the following is a description.

'This invention relates to seating for various uses and particularly for use in the manufacture of seats of the type commonly employed in railway cars.

The object of the invention is to provide a seating, the parts of which are all, or substantially all, made of metal and which is therefore fireproof. This objectis obtained .by the employment of a metallic frame and a covering stretched over and secured to the frame, this covering being formed of substantially flat, metallic strands, closely interwoven. Such a covering, I have found, possesses the requisite flexibility, wears well, can be manufactured at small cost, and presents an attractive appearance, in addition to being fireproof. In the construction of such a metallic covering, it is desirable to use strands of metal which is rather soft and pli able in order to facilitate the operation of weaving, of carrying the covering around and under the members of the frame and of folding the covering at the corners of the frame. ability of these metal strands, the usual springs for yieldingly supporting the covering of the seating might not furnish a suflicient yielding support for the covering at all oints on its surface and therefore the coverlng, after being depressed at certain points, might not be returned to its original position, presenting a smooth resilient surface. To guard against this, I provide a means, additional to theusual spiral springs, for yieldingly supporting the covering, this means consisting of a plurality of strips of springmetal underlying the woven metallic covering. These strips may be woven into the covering on the under side thereof at intervals across it in one or both directions, or they maybe woven se arately to form an open mesh structure whicff/lies directly under ut is separate from the covering. lhese strips of spring-metal need only be of such size as to underlie the central ortion or top surface of the seating, but, if esired, some or all of the strips may extend over and down along the outer sides of the frame members. Those By reason of the softness and pli' strips adjacent to the edges of the covering, however, should not extend out to the ed es for the reason that it is usual to make foIds in the covering at the corners of the frame and the spring-metal strips would make such folding more difficult.

The )referred embodiment of the inven tion is illustrated in the accompanying drawings, in which Figure 1 is a sectional elevation of acushion such as may be used as the seat-cushion of a car-seat; Fig. 2 is a detail view, in plan, of a portion of the covering on an enlarged scale; and Fig. v3 is a section on line 3-3 of Fig. 2.

Referring to these drawings, the cushion consists of a rectangular frame formed of four sheet-metal fra1nerne1nbers 1, secured together at their ends. Each of these framemembers has an inwardly curled flange 2 at its upper edge, an inwardly extending flange 3 at its lower edge, and a curled portion 4 at the edge of the flange 3. Extending across between op osite side members of the frame and securerl at their ends thereto, are a plurality of channeled metallic slats 5, each supporting a plurality of spiral springs 6. Each row of springs 6 su ports on the upper ends thereof a flat meta hc spring 7, the ends of which are turned down alongside the framemembers 1. The metallic covering 8 is drawn over the flat springs 7 and down along the members 1 of the frame, the edges thereof being carried over the flanges 3 and around the curled portions 4. Metallic clamping members 9 are gripped around the covering and the curled portions 4 to secure the edges of the covering to the frame.

The covering consists of a plurality of strands 10 and 11 of soft, pliable metal, closely interwoven. Any suitable weave of the strands may be employed, as for instance the square weave shown in Fig. 2 or a twill weave. In the drawin s, I have" shown the strips 12 of spring-meta interwoven with the strands of the covering and this is the construction I prefer to use, but, if desired, the strips may be separate from the covering. In either case, the strips 12 are on the under side of the covering and hence do not show from the exterior of the cushion. In the construction illustrated, each of the strips 12 directly underlies, and is woven with, a strand of the covering. The intervals between the stri s 12 may be varied as desired but prefera ly the strips are about an inch apart.

sisting of flattened, pliab To secure the results for which the strips 12 are provided, it is only necessary that they extend across the central portion of the covering, that forming the top of the cushion. They may, however, be of such length that their ends extend down along the frame members 1 a short distance as indicated by the dotted lines 13 in Fig. 1, or theyi may extend to the edge of the covering; referably the strips 12 lying adjacent to the members 1 of the frame are much shorter, so that they do not extend down along the members of the frame at all, for the reason that it is necessary to fold the covering at each of the corners of the cushion so as to make a neat structure and the strips being far less liable than the strands 10 and 11 would ma e the oppration of folding the covering more difficu t.

The strands 10 and 11 are preferably flat strips, as indicatedby the sectional view in Fig. 3, but if desired the outer surface of these strips may be somewhat, convex and the covering may have a coating ofan incombustible or other enamel applied to the outer face thereof. The strips 12 are also substantially fiat and preferably of the same width as the strands 10 and 11. It will be seen that by this construction, the cushion is of metal throughout, the covering is flexible and after the covering has been depressed it will be forced back to its original position by the strips 12, since the latter are made of spring-metal. The springs 6 and 7 form a ielding support for the covering of the cushion, but might not be sufficient to prevent the covering from being dented and taking a set in a shape other than that desired, on account of the spaces between them, but such denting and setting of the strands 10 and 11 is effectually prevented by the strips 12.

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