WILLIAM A. MURRAY AND WILLIAM A. MIJ'RRAY, JR., F CINCINNATI, OHIO, ASSIGN- ORS TO THE WILLIAM A. MURRAY SPRING COMPANY, OF CINCINNATI, OHIO, A

CORPORATION OF OHIO.

SPRING-SEAT.

RAY and WILLIAM. A. MURRAY, Jr., citizens of the United States of America, and residents of Cincinnati, county of Hamilton, and State of Ohio, have invented certain new and useful Improvements in Spring-Seats,

of which the following is a specification;

This invention relates to spring seats, in which the supporting frame has a covering of fabric or leather.

In the art preceding our invention there were used several means for securing the covering to the supporting frame. With wooden frames it was customary to tack the covering to the wood. Where the frame was metallic, it was customary to place a piece of leather or .fabric across the bottom of the frame, and to sew the leather or fabric of the sides thereto. In other instances, with metallic frames it was customary to sew a binding cord to the lower edge of the fabric or leather, and to clamp the binding cord to the frame.

It is the object of our invention to provide a covered spring seat, in which the covering is secured to the bottom of the seat, without tacking, sewing, or a binding cord. 'This object is attained by the means described in the specification, and illustrated in the accompanying drawings, in which,

Figure l is an inverted lan view of a spring seat embodying our invention. Fig. 2 is a sectional view upon a somewhat enlarged scale, taken upon irregular line 22 .of Fig. 1. Fig. 2 is "a detail sectional view of the cushion, the top frame, and the side covering, taken likewise upon line 2-2 of Fig. 1. Fig. 3 is a sectional view, taken upon line 33 of Fig. 1. Fig. 4 is a perspective view of a spring seat embodying our invention. Fig. 5 is a detail perspective view upon a somewhat enlarged scale, of the end of a cross strip embodying our invention.

Referring to the parts: The spring seat embodying our invention comprises top and bottom substantially rectangular metallic frames A, B, transverse spring supporting metallic cross strips D, vertically disposed coiled springs E, whose lower ends rest upon the cross strips, tie wires coupling the top coils of the springs to each other and to the top frame, a cushion.

(1 are struck upward, to form perforations,

through which the lower coils e of the springs E are threaded, to secure the springs to the cross strips. The ends of the cross strips have an upturned flange (13 which is curled around the bottom frame, to secure the strip thereto.- Adjacent to each of its ends, each cross strip D has a transverse offset d". The cross strips are secured to the bottom frame in a position such that the offset d" projects inward, so that they form recesses, into which the adjacent parts 9 of the edges of the covering G fit, when the covering is drawn around thebottom frame.

The clamps H are elongated strips of metal, the edges of which are inturned, so as to make the strips U-shaped in cross section.

We have shown four of these strips, substantially of the length of the side which they engage of the frame. In securing the coverm drawn down around the frame; a clamp is then placed over the covering and the frame and is compressed about the frame, the covering, and the flanges d of the cross strips.

The seat embodying our invention has a smooth and level bottom edge, which is adapted to rest upon a vehicle seat. The bottom of the seat being open makes our spring seat one which is fully ventilated.

What we claim is:

1. In ,a spring seat the combination of a bottom frame, cross strips secured to the to the bottom frame, its edges are frame and having inwardly projecting oifsets adjacent-to the frame, a covering whose edges embrace the frame and fit into the offsets, and clamps embracing the lower edge of the covering and the frame.

2. In a spring seat the combination of a bottom frame, cross strips having flanges at their ends encircling the frame and transverse oflsets adjacent to the frame, a covering whose lower edge embraces the frame 2 and fits into the offsets, and clamps mmcsubscribed ournaines this 29th'da'y of July,
