To all 'whom it 711mg/ concern.'

Be it known that we, DANIEL ll. GAIL and JOHN F. GAIL, both of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in loven-lire Mattresses and Seats, duc.; and we do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying' drawings, and to the letters of reference marked thereon, making a part of this specification.

Our invention relates, primarily, to the manufacture of woven-wire mattresses or bed-bottoms, and has for its object to simplify the construction thereof, and to produce at the least possible cost a thoroughly durable and elastic portable metallic mattress, said in' vention being likewise applicable to the manufacture of elastic seats and backs for sofas, chairs, tir-c.; and it consists in the details of construction and combination of parts here inafter described and claimed.

In the accompanying drawings, Figure l is a view in perspective of oui-improved double metallic mattress; Fig. 2, a plan view of the under side of one end thereof; Fig. 3, a detail, on an enlarged scale, of a portion, of the top thereof; Fig. et, an elevation in perspective of one of the spiral springs detached; and Fig. 5, a detail, on the same enlarged scale, illustrating in elevation 011e of the springs when interposed and secured in position between the two faces of the mattress in accordance with our invention. Fig. (5 is a plan view broken away, showing the manner of hinging the upper frames and apply:Y

ing the transverse tie-wires.

The improved double mattress is construct ed of an upper facing or section, A, which is made to extend in an unbroken sheet from side to side of the bed, and of two longitudinal lower sections hinged together lengthwise by means of the upper section, to which they are attached. Each of these sections A and O C is formed of spiral-wire strands interwoven in the manner well known to the art to constitute a iiexible and elastic metallic sheet, the spiral coils being made to run lengthwise thereof in the usual manner.

The unbroken upper facing or section, A, of woven wire, is stretched upon two metallic frames, B B, each of which is formed of a single iron bar bent to inclose three sides of a rectangle, the fourth side being left open. It is re-enforced and elastically stayed by means of transverse spiral coils G G, of wire, extending at intervals from side t-o side thereof at right angles with the longitudinal interwoven strands of the sheet. Said transverse spirals are preferably carried Athrough transversely within the interwoven. coils of the longitudinal strands, as shown in Fig. 5, so as not to project beyond the same on either face, leaving the inner as well as the outer face smooth and even. By this transverse arrangement of the spiral coils or wires G G the longitudinal wires of the web are supported at regular intervals. The web will thus yield to the shoulder, hips, or other projections of the body and yet lie close to and support the rest of the body and accommodate itself to all the undulations thereof, which, it is apparent, is not the case with longitudinal wires. The transverse arrai'igement of the spiral coils or wire, it will be apparent, will also brace and strengthen each half of the mattress, and thereby also strengthen the hinge-connection between the parts by connecting in the continuous web with the central longitudinal cord or wire.

The two frames B B are placed so as to bring their open sides, opposite each other at the middle of the woven-wire sheet A, at which point the ends of the wire frames B B are bent inward and enter adjacent coils of the woven web a, as shown in Fig. l, which thus becomes a hinge for said frames B B, so that they may be folded over on said middle line e e, one upon the other. (See dotted lines, Fig. l.)

The lower face of the double mattress or bed-bottom is made up in two sections, C O', of equal dimensions, correspoi'iding each to one-half or division of the upper section, A. Each of these lower sections, C l', is constructed of a metallic frame formed of an iron rod or bar, D, bent into a rectangular form, and upon which is stretched the interwoven wires forining the section, and which are made fast to the frame in any suitable manner. Each lower frame is `17e-enforced and stiffened by a series of straight rigid IOO transverse rods or tie-wires, K K, extending at regular in tervals centrally within the coils from one side bar to the other and secured to cach, as shown in Fig. 2. The division between these two lower sections coincides with the central line, e c, Fig. l, upon which the upper unbroken section, A, folds on hinges, so that the one lower section, C, maybe folded over upon the other, C', on said line, and when thus superimposed their edges will coincide throughout.

The upper and lower sections, A and C C', are united to form the mattress by means of interposed double helical springs F F F.

Loops H H (see Fig. 4) are formed at diametrically-opposite points on the outer coils of each of said helical springs F to project between theturns of the coiled strands of the mattress when the spring rests against or upon the same, as shown in Fig. 5, and the springs are secured to the lower sections of the mattress or bed-bottom by means of the straighttransverse rods or tie-wires K K, which are made to engage the loops H H, and to the upper section by means of the spiral strands or reentorcing coils G, of'wire, run through and within the interwoven coils ot' the longitudinal spiral strands of said section transversely across the section, and which engage the loops H H of the opposite end of the springs, as shown in Fig. 5. The springs F F are thus securely tied to the upper and lower sections, A C C', of the mattress, so that they may not be displaced or overturned and operate to bind the section together.

. It will be apparent that the arrangement of the transverse tie-rods K or spiral coils l may be reversed or that one may be used in lieu of the other.

le contemplate the use of our invention in the seats and backs of sofas, lounges, &c., as well as for beds.

le claim as our inventionl. The combination, in an elastic wovenwire mattress or bed-bottom, of the unbroken or continuous upper-section, A, of interwoven Wires, the two frames B B, supporting the same and having the inturned meeting ends entering and engaging coils of said upper section and forming a hinge, whereby the bedbottom maybe folded, the two separate lower Y sections, C C', of similar wires, the interposed spiral springs connecting said upper and lower sections, substantially as and for the purpose described.

2. rlhe combination, in an elastic wovenwire mattress or seat, of the continuous or unbroken upper web of interwoven spiral wires, the two-part wire frame upon which the same is stretched, and the transverse re-enforcing spiral coils or tie-wires formed in two sections, each united at one end to the wire frame and extending th rough the coils of the woven-wire web and attached to the central cord or wire thereof, substantially as specied.

The combination, in an elastic wovenwire mattress or seat, of the woven-wire facing, the helical springs having loops H H projecting from their outer coil, and the tie-wires carried transversely through said loops and within the spiral coils oli' the woven-wire facing, whereby the sprin gs are connected to said facing, substantially in the manner and for the purpose set forth.

4. The combination, in an elastic wovenwire mattress or seat, of the two outer facin gs severally formed of metallic frames an d woven wires stretched upon said metallic frames, the interposed helical springs having loops H ll projecting from their-outer coils to pass in between the coils of the woven wires, the transverse straight tie-wires passing through the coils of one of said facings and engaging the loops at one end of the springs, and the spiral tie-wires passing centrally and transversely through the coils of the woven wires and the loops at the opposite ends of said springs, all substantially in the manner and for the purpose herein set forth.

5. The combination, in a wover-wire bedbottom, of a frame, a continuous woven-wire fabric attached thereto, andre-enforcingwires,.

spiral coils, or rods separate therefrom, running transversely of said bed-bottom, secured at their ends to said frame, and connectedto the fabric by engaging the coils thereof, substantially as described.

In testimony whereof we have signed our names to this specification in the presence of two subscribing Witnesses.
