Patented May 31, 1932 UNITED STATES PATENT OFFICE LOUIS E. PITTONI, OF JAMAICA, NEW YORK, ASSIGNOR TO THE ROME COMPANY, INC., A CORPORATION OF NEW YORK CONNECTION BETWEEN SPRINGS AND FRAMES Application filed February 10, 1930. Serial No. 427,108.

The present invention relates to bed springs or other cushions composed of connected vertical coiled springs surrounded by an enclosing frame of heavy wire lying approximately in the plane of the tops of the springs.

The object of the invention is to produce a simple and novel connection between the frame and the adjacent coiled springs.

The various features of novelty whereby 110 my invention is characterized will hereinafter be pointed out with particularity in the claims; but, for a full understanding of my invention and of its objects and advantages, reference may be had to the following deiifi tailed description taken in connection with the accompanying drawings, wherein:

Figure 1 is a plan view of a bed spring embodying the present invention, only a portion of the coiled springs being shown; Fig.

2 is a plan view, on a much larger scale than Fig. 1, showing fragments of the frame and one of the coiled springs and the connection between the same; Fig. 3 is a section on line 3-3 of Fig. 2, on a still larger scale; and Fig. 4 is a view similar to Fig. 3, showing a modification. 7

Referring to Figs. 1 to 3 of the drawings, 1 represents a frame, composed of a heavy wire or light rod surrounding a cushion composed of many vertical coiled springs 2, 2;

the frame and the spring cushion being of any usual or suitable construction.

In accordance with my invention, I secure the frame to the upper turns or coils of the adjacent springs, that is, the springs forming the border of the cushion, by means of simple clips extending around the wires of the springs and welded to the frame. These clips are preferably made of strips of sheet metal. In the arrangement shown, each clip is made of a long rectangular piece of sheet metal bent upon a transverse line about midway between its ends to produce two wings 3 and 4 lying flat upon each other and connected by a tubular section 5 fitting around the wire in the upper turn of one of the springs. The parts 3 and 4 are preferably of such length that when the clip is brought up against the under side of the frame, the free end of the clip lies inwardly from the vertical plane containing the long axis of the frame wire; the spring and the frame wire being so positioned that the elements 3 and 4 extend downwardly and laterally to come into contact with the frame. The free end of the clip and the frame are then welded together with the welding contacts on a line extending inwardly and downwardly. The spring is thus firmly connected to the frame, and the free end of the clip lies a considerable distance inwardly from the vertical plane tangent with the outside of the frame. Consequently, if there should be any roughness at the end of the clip, the danger of tearing the bed clothing by contact therewith is eliminated, because the frame will hold the bed clothing far out from the adjacent end of the clip.

If desired, the strip from which the clip is formed may be longer than that required to produce the clip shown in Fig. 3, so that the engaged wing sections thereof, as indicated at 6 and 7 in Fig. 4, may be curved toward the end of the clip so as to fit against the under side of the frame and extend outwardly beyond the vertical plane containing the long aXis of the frame.

It will thus be seen that I have produced a simple and novel means for connecting the surrounding frame to the adjacent wires of a spring cushion, without requiring special attention to be paid in finishing the edges at the free ends of the strips or bands of which the strips are made, because the points at which there may be a little roughness are so positioned angularly of the wire or rod of which the frame is constructed that the bed clothing will not catch on the same. Consequently the frame and the springs may be assembled quickly and at low cost, with the assurance that the fastenings between the springs and the frame will not be displaced along the latter in use. Furthermore, the material of which the clips are made may be thin so that the parts of the frame that are normally visible when the bed spring is on a bed present either an entirely smooth surface or, in the case of the clip shown in Fig. 5, a surface that is for all practical purposes smooth and continuous.

lVhile I have illustrated and described with particularity only a single preferred form of my invention, with a few modifications, I do not desire to be limited to the 5 exact structural details thus illustrated and described; but intend to cover all forms and arrangements which come within the definitions of my invention constituting the appended claims.

I claim 1. In a bed spring, a group of vertical coiled springs, a frame of wire surrounding said group and positioned in about the plane of the upper turns of the spring, individual clips in the form of pieces of sheet metal each bent around and completely enclosing the wire of the upper turn of a spring and having the end portions resting flat against each other, and said end portions extending from the said wires of the upper turns of the springs underneath the frame wire and being welded thereto.

2. In a bed spring, a group of vertical coiled springs, a frame of wire surrounding i225 said group and positioned in about the plane of the upper turns of the spring, individual clips in the form of pieces of sheet metal each bent around the wire of the upper turn of a spring and having the end portions resting flat against each other, and said end portions extending underneath the frame wire and being welded thereto, the extreme end of each clip lying inwardly from a vertical plane containing the long axis of the corresponding part of the frame wire.

In testimony whereof, I sign this specification.

LOUIS E. PIT'IONI.
