WIRE SPRING-MATTRESS.

SPECIFICATION forming part of Letters Patent No. 614,010, a d November 8, 1898.

Application filed May 1 9, 1 89 8.

To all whom it may concern.-

Be it known that we, JACOB S. KNEOHTEL and ROBERT GEORGE VINCENT, of Hanover, in the county of Grey, Province of Ontario, and Dominion of Canada, have invented certain new and useful Improvements in Wire Spring-Mattresses, of which the following is a full, clear, and exact description.

The object of the invention is to provide certain new and usefulimprovements in wire spring-mattresses whereby the several parts can be readily taken apart to permit of packing the mattresses in pairs within a small compass for shipment,'the construction also allowing of conveniently setting-up the several parts to form the mattress and of stretching the wire fabric to the desired degree to produce an elastic, springy, and smooth surface adapted to yield properly when the mattress is in use.

The invention consists of novel features and parts and combinations of the same, as will be described hereinafter and then point-- ed out in the claims. V i i Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure'l is a perspective view of the improvement. Fig. 2 is a like view of two mattresses folded up and packed into a single bundle. Fig. 3 is an enlarged side elevation of the adjusting device for the terminal beam, part being shown in section. Fig. 4is an enlarged plan view of part of the improvement, and Fig. 5 is an enlarged side elevation of one of the soft-wire connecting-links.

The improved wire mattress is provided with two side rails A A and terminal cross beams B B, of which the beam B is rigidly secured in position on one end of the rails by bolts 0, while the other beam B isadjustably held by bolts D in the slotted ends A of the rails A A. The inner edge of the beam B is engaged by bolts E, extending longitudinally and mounted to screw in nuts E, secured to the top of the rails A A, so that the beam B can be readily adjusted longitudinally on the side rails when the nuts of the bolts D are loosened to give the desired tension to the wire fabric F, secured at its ends Serial No. 681,141. (No model.)

to the beams B Band at its sides to the rails A A, as hereinafter more fully described. The wire fabric F is formed of longitudinal strands F, made of springwire and formed with horizontally disposed coils F F arranged alternately on opposite sides, as is plainly indicated in Fig. 4. Theends of the strands F are formed into loops F each adapted to hook onto a peg, nail, or like projection G, secured to the terminal beams B B, the end of the loop of one strand hooking onto the end coil F or F of the adjacent strand, as will be readily understood by ref erence to Fig. 4. Adjacent coils F F of adjacent strands are connectedwit each other by a connecting-link Fflpreferab y made of soft wire and formed at or near its middle with a coil F and at its ends into hooks F for engaging and conveniently closing the corresponding loops F 1? of adjacent strands. The coils F F on the side edges of the fab ric F are engaged by longitudinally-extending rods H, preferably made of strong wire and held on transverse links I, engaging staples J, secured to the top of the rails A A. The ends of the rods H are preferably fitted into apertures in the terminal beams B B, so that the said rods do not present projecting ends.

Now it is evident that by the construction described a very strong wire fabriois produced, having a smooth surface and capable of standing almost any strain, no matter in which direction the strain is applied. When the mattress is loaded and the strands tend to straighten, then the moment the load is re- -moved the reaction from the straightened condition again gives the strands the zigzag formation shown in the drawings.

When it is desired to fold themattress, the bolts 0 and D are disconnected from the rails and the screw-rods E are run inward. Then the loops F are unhooked from the pegs G to permit of rolling the wire fabric into a roll. For shipment We prefer to pack the foldedup mattress together, as illustrated .in Fig. 2, the two rolls of wire fabric and the terminal beams being placed between the two pairs of side rails and connected with each other at their ends by short boards K and the bolts (J and D, boards L closing portions of the Ice connected side rails to prevent the terminal beams and the rolls of wire fabric from falling out between the said rails.

It is clear from the foregoing that two mattresses folded up into one single bundle, as shown in Fig. 2, take up very little room, and consequently can be conveniently shifted from one place to another. It will further be noticed that it requires a comparatively small amount of wire to form a very strong and durable piece of wire fabric. The coils F F are placed at equal distance apart to give the fabric a fine symmetrical appearance. By making the connecting-links of soft wire the end hooks thereof engaging the coils F F can be easily and properly closed to form a smooth joint and at the same time maintain the necessary yielding properties of the spring-wire strands and their coils. The coil F in the connecting-link F may be omitted, if desired.

Having thus fully described our invention, we claim as new and desire to secure by Letters Patent 1. A wire spring-mattress comprising side rails, terminal cross-beams, one of which is secured to the rails, the other being adjustably secured thereon, side rods extending longitudinally, links for supporting the rods from the side rails, and a wire fabric formed of strands having coils extending alternately on opposite sides and having diagonal connecting-links for connecting adjacent coils of adjacent strands, the coils on the sides of the fabric being engaged by the said side rods, and the ends of the strands being formed into loops for removable connection with pegs on the terminal beams, substantially as shown and described.

2. A wire spring-mattress comprising side rails, terminal cross-beams, one of which is secured to the rails, the other being adjustably secured thereon, side rods extending longitudinally, links for supporting the rods from the side rails, and a wire fabricformed of strands having coils extending alternately on opposite sides and having diagonal connecting-links for connecting adjacent coils of adjacent strands, the coils on the sides of the fabric being engaged by the said side rods and the ends of the strands being formed into loops for removable connection with pegs on the terminal beams, the loop of one strand being also connected to the end coil of the next adjacent strand, substantially as shown and described.

3. A wire spring-mattress comprising side rails, terminal cross-beams, one of which is secured to the rails, the other being adjustably secured thereon, side rods extending longitudinally, links for supporting the rods from the side rails, and a wire fabric formed of strands having coils extending alternately on opposite sides and having diagonal connecting-links for connecting adjacent coils of adjacent strands, the coils on the sides of the fabric being engaged by the said side rods, the ends of the strands being formed into loops for removable connection with pegs on the terminal beams, the strands being made of spring-wire and the links of soft wire, substantially as shown and described.
