Specification of Letters Patent.

Patented Mar. 13, 1917.

Application filed April 28, 1915. Serial No. 24,383.

To all whom it may concern:

Be it known that I, CLARENCE A. HILLS, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Upholstery, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to upholstery and an object of my improvements is to provide an improved construction for the cushioned portion of a seat especially for the backs of seats for automobiles which shall maintain its shape and obviate the necessity of tuftmg.

I secure this object in the device illustrated in the accompanying drawings in which Figure 1 is a. sectional elevation of an apparatus embodying my invention and so much of a seat as is necessary to show its connection therewith.

Fig. 2 is an elevation looking at the plane of the cushion surface, the covering material being cut away to show the internal constructlon.

Fig. 3 is a detail view partly broken away and having parts removed to show the construction and illustrate the mode of assembly.

Fig. 4 is a sectional elevation of a single sustaining spring and its adjacent parts.

Figs. 5 and 6 are detail sectional views illustrating a mode of construction.

a is the horizontal portion of the seat and b b is the frame of the back of the seat. 0 is a strip of metal extending with its edges in a vertical plane and secured to the frame I) by nails 0 the upper end of said strip being bent to conform to the upper cross piece of the frame 6. There are a series of strips a closely adjacent and parallel to each other and forming practically a continuous surface at the inner portion of the frame 6 b, as indicated in Fig. 2.

d d are coil springs extending at right angles from a strip 0, as shown in Figs. 1 and 4.. The inner coil of each of the springs d is secured to a strip 0 by lugs c struck out which are of equal length and normally in 1 a single plane. A single strip f f rests upon the outer ends of the springs d which extend from a single strip 0.

The portion of the wire of which the strip f is composed which comes at the center of the outer coil of a spring d is, bent downward, as shown at f A loop 0 is struck u from the metal strip 0 at the part thereo that comes at-the center of the inner coil of each of the springs d. t

A string e is tied at one end to each of the loops 0 and at the other end to a loop i The strings e position the outer ends of the springs at so that the outer ends of said springs come in the desired surface, as shown in Fig. 1.

The outer coil of each of the springs d is secured by four bands 7 f to the wire strip 7, as shown most distinctly in Figs. 3 and 4, each of the bands f passing around the wire of one of the loops of the band f and around the outer coil of the spring.

There is a wire strip 7 above, and practically of the same width as, each of the strips 0. The strips f therefore come close together at their edges and together they form a practically continuous surface. Each of the bands 7 terminates at its lower end F, at a distance from the seat and is unattached and at its upper end 7 it is also unattached and at some distance from the seat back or frame 6.

Over the surface formed by the wire strips 7 a sheet of textile material 9 is passed and over this sheet a thick integral sheet 9 is placed and over this latter a finished sheet of leather or other proper material is secured.

The sheet 9 may be of cotton-batting quilted between burlap to the thickness of say one-half inch.

Inasmuch as the strips f form a universally yielding surface composed of wires that are close together the cover described is suflicient and will permanently retain its form and it is unnecessary to use horsehair or other stufling and tufting is avoided. The 'Wires in the surface formed by the strips f are about i} of an inch apart. With these dimensions the covering material Will not sink between the Wires to an objectionable extent.

What I claim is:

1. In a spring cushion, a plurality of upright spiral springs, a strip formed of looped Wire the loops being of a length approximately equal to the diameter of the outer spire of said springs, said strip passing over said spring so as to cover the outer spires thereof to form a continuous surface of closely adjacent Wires and sheet material passing over said strip.

2. In a spring cushion, a plurality of upright spiral springs, a strip formed of looped wire the loops being of a length approximately equal to the diameter of the outer spire of said springs, said strip passing over said spring so as to cover the outer spires thereof to form a continuous surface of closely adjacent wires and sheet material passing over said strip, the Wires forming said loops being secured to the Wire forming the outer spire of said springs at points formed of looped Wire said loops being of a length approximately equal to the diameter of the outer spires of said springs, passing over each row of said springs, said strips being parallel and adjacent to each other so that they shall form a continuous surface of closely adjacent Wires and sheet material passing over said strip.

4. 'In a spring cushion, a plurality of upright spiral springs, a strip formed of looped Wire the loops being of a length approximately equal to the diameter of the outer spire of said springs, said strip passing over said spring so as to cover the outer spires thereof to form a continuous surface of closely adjacent wires and sheet material passing over said strip, the ends of said strip being unattached and so located that they shall have freedom oi movement.

In testimony whereof I sign this specification.

CLARENCE A. HILLS.
