seams-SEAT STRUCTURE.

To all. whom at may concern:

Be it known that 1, JAMES H. Coon, a citizen of the United States, residing at Detroit, in the county of Wayne, State of Michigan, have invented certain new and useful Improvements .in Spring-Seat Structures; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to a spring seat or spring cushion construction, and consists inthe peculiar arrangement and association of parts hereinafter fully set forth and pointed out particularly in the claims.

The object of the invention is to provide a structure wherein provision is made for quickly and securely mounting the springs of an upholstered seat or cushion so as to firmly retain them upon the supporting frame, and

wherein the arrangement is such as to enable the springs to be quickly mounted and readily removed, and at the same time produce a smooth and compact structure.

The above object is attained by the arrangement illustrated in the accompanying drawings, in which z Figure 1 is a plan view of a seat or cushion frame made in accordance with my invention.. Fig. 2 is a transverse section, as on line 2'2 of Fig. 1. Fig. 3 is a fragmentary view in perspective of two of the'crossed straps of the frame. Fig. 4 is a fragmentaryview in plan, showing a modification of the structure.- Fig. 5 is a transverse section through one of the metal straps having the openings therethrough. Fig. 6 is a fragmentary view. in longitudinal section through the other of the crossed straps, showing one of the loops adapted to enter and lie in the openings of the first mentioned strap.

Referring to the characters of reference, 1 designates a rectangular frame formed pref erably of strong wire of suitable gage, across which extend in one direction the metal straps 2 whose terminals are formed into eyes 3 which embrace the wire 1 of the frame. Struck up from the body portion of each of the straps 2 are a number of loops 4. Crossing the straps 2 transversely are the metal straps 5 whose terminals are provided with Specification of Letters Patent.

being provided with apertures, 7 regis j ter with and receive the loops 4f'of the straps? 2, said loops passing through said apeltliiesk.

and extending above the; timeouts-snaps- 5. By this arrangementthecrossed-straps of the fabric are securely united at their.

points of juncture and are firmlyheld against lateral displacement. Mounted-upon said stra s at the points where theycros's'atright ang es are the spiral springs-"8 which rest upon said crossed straps and are confinedin place by means of the locking rods 9 which lie upon and cross the lower coils 10 of said same time securely fastening the springs to said straps so as tomaintain them firmly in .a vertical position.

To prevent lateral displacement of the springs, there may be struck u from the cross straps 2 and 5, the lugs 11 W ch engage the lower coils 1.0 of the springs, as shown, and prevent said springs shifting.

By the arrangement herein shown and dee scribed, a firm support. is provided for the base of the spring which maintains it in a vertical position, and at the same time provision is made for uniting the crossed :wmx. which support said spring by means of locking rod 9 which crosses the lower coils of said springs and passes through the upwardly projecting loops of the straps 2. It will be observed that where the bar or strand 9 is made continuous, asshown Figs. 1, 2, and 3, it serves as a truss to brace the straps 5 and add to the carrying strength thereof, en. abling the use of comparatively light material in said straps. It will further be observed that the frame formed of the rectangular marginal strands 1 and the crossed. stra s 2 and 5 is comparatively smooth upon the ottom side, thereby greatly facilitating the work of upholstering.

In some instances it may be desirable toform the structure in narrow straps or sections, as shown in Fig. 4, in which case the straps 5 will be short, as shown in said Fig. 4 as well as the locking rods 9 which will correspend in length'to said short straps.

Having thus fully set forth my invention,

springs and pass through the loops 4 of the what I claim as new and desire to secure'by Letters Patent is I 1. In a spring seat structure, the combination of the crossed metal straps, one of said straps having a locking member which passes through the other strap, a spring seated on said-straps at their point of crossing and a locking bar en aging the lower coil of said spring and saiddocking member.

V 2. n a spring seat structure, the combination of a plurality of metal straps crossing at right an les, a number of said straps being provide with apertures and the remaining ortion of said straps being provided with oops which pass through said apertures to tie the straps together, springs seated upon said straps at the juncture thereof, and a locking bar passing over th'elower coils of said springs and through said loops to tie the parts together.

3'. The combination in a spring seat structure, of the longitudinally extending strap adapted to support a spring having a loop formed therein, a transverse strap having an 26 aperture to receive said loop, a spring mounted upon said crossed straps, and a locking rod passing over the lower coil of said spring, and through said loop.

4. In a spring seat structure, the combination of the crossed straps, one of which is provided with an a erture and the otherv with a loop passing t rough said aperture, a coiled spring seated upon said crossed straps, and means engaging in said loop and bearing upon the spring to lock said spring in position. a

5. In a spring seat structure, the combination of the crossed straps forming a support for the spring, one strap having an aperture therethrough, and the other having a projecting member which engages in said aperture, means for looking the straps together and the spring thereto,,-and means for preventing lateralmovement of the spring.

In testimony whereof, I sign this specification in the presence of two witnesses. JAMES H. COOK.
