WIRE MATTRESS.

SPECIFICATION forming part of Letters Patent No. 547,743, dated October 8, 1895.

' Application filed August 30,1894. Serial NO- (N0 mod-9L) To all whom it may concern:

Be it known that we, MELVILLE F. SHAW and JOHN F. GAIL, of Ingalls, county of Madison, State of Indiana, have invented certain new and useful Improvements in Wire Mattresses; and We do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompa nying drawings, in which like figures refer to like parts.

Our invention relates to a wire-spring mattress consisting of frame wires, spiral springs, tie-wires, and loops or links securely combining the parts, as hereinafter described, and as shown in the drawings forming a part hereof.

In the drawings, Figure l is a plan view of our mattress. Fig. 2 is a perspective of one corner of the mattress, showing four springs. Fig. 3 is a sectional view on the line A A, Fig. 1. Fig. 4 isthe same view on the line B B, Fig. 1, and Fig. 5 is a perspective showing a spring and its connections.

There are two frame-wires l-one above and one belowextending about the mattress. While these are preferably made of wire, they may be made of other material. Extending from one side to the other of these frame-wires and in both directions are tie-wires 2, and between the upper and lower series of tie-wires are placed the spiral springs 3, made, preferably, double-cone shaped, as shown, and secured at the points of intersection of the tiewires. The tie-wires are straight, and the ends of the springs are regular in their curvature and flush with each other, with the tie- Wires crossing them, whereby a smooth even surface is presented, which is a desideratum in the sale and especially in the use of wire mattresses. Such a surface wears the bedding less than when rough, as is so often seen. The springs are held in place by loops or links 4, formed as shown, extending under the top coils of the springs, with the ends bent up over the crossing tie-wire. In this manner the adjacent sides of the springs are connectedand the ends and tie-Wires secured to each other. The side of each spring adjacent the frame-wire issecured to it, also, by a link.

The space between the rows of springs is closed by a series of auxiliary tie-Wires 5, which may extend in one or both directions, as desired. These auxiliary tie-wires, however, are bound by the links, inasmuch as they extend between the series of tie-wires and links, as shown.

The two sides of the mattress are similarly constructed. When a fabric-covered mattress is desired, the tie-wires are extended under the top coil of the springs, as shown, and the links are inverted, their ends extending down through the fabric past the spring-wire and bent around the tie-wire, thus binding the fabric, springs, and tie wires together securely.

The manufacture of this mattress is simple, as both classes of tie-wires are straight and inserted after the springs are in place and while holding the links in place one after the other, the links havingbeen separately formed with eyes through which the tie-wires may be passed. The links engaging the frames are then placed,w hereby the springs are stretched apart. Thismattress is very strong and durable and presents two smooth level nicelooking surfaces. The ends of the springs being closed by tie-wires and all combined by links, it is impossible for the springs to telescope or lean, and the mattress will have increased tension and cannot warp while standing in stock.

What we claim as our invention, and desire to secure by Letters Patent, is-

1. A wire mattress comprising frame wires, spiral springs, straight tie wires extending centrally across the mattress in both directions, links connecting the adjacent springs to each other and to the frame wires and also securing the tie wires and springs together at their intersection, and auxiliary tie wires extending between the rows of springs and between the links and tie wires, substantially as shown and described.

2. A wire mattress comprising an upper and lower frame wire, spiral springs arranged in rows in both directions, a series of straight. tie wires extending centrally across the upper and also the lower ends of the springs, links connecting each end of the springs to the ad- In Witness whereof we have hereunto set jacent springs and to the frame wires and our hands this 22d day of August, 189i. also securing the tie wires and springs together at their intersection, and auxiliary tie MELVILLE F.
