UNITED STATES PATENT OFFICE.
LOUIS E. PITTONI, 0F JAMAICA, NEW YORK, ASSIGNOR TO THE ROME COMPANY, INC, A CORPORATION OF NEW YORK.
INTERLOCKED HELICAL SPRING.
Application filed April 11, 1927. Serial No. 182,988.
The present invention relates to spring cushions and particularly to that type oi cushion in which there are vertical spiral springs whose upper turns or rings are tied together by crossed small helical springs.
"The'object of the present invention is to bring about in a simple manner a looking together of the tie springs to prevent relative displacement thereof out of the plane containing them.
In an application of Darwin Hanauer, Serial No. 171,059 the need for fastening the tie springs together is explained and means tor accon'iplishing that purpose are dis closed. In one of its aspects the present invention may be. regarded as comprising a specific form of the invention set forth in the aforesaid application.
The various features of novelty whereby the present invention is characterized will hereinafter be pointed out with particularitv in the claim; bun for a full understandin of the present invention and of its objects and advantages, reference may be had to the following detailed description taken in connection with the accompanying drawing. wherein:
Figure 1 1S a plan view of a fragment of.
a spring cushion embodying the present invention; Fig. 2 is an elevation on a larger scale of the middle section of one of the tie springs; Fig. 3 is a plan view of the tie springs, interlocked; and Figs. l and 5 are sections taken respectively on lines l---l and 5-5 in Fig. 3.
Referring to the drawing, 1, 2, 3 and t represent fragments of the top coils or rings of tour adjacent main spiral springs in a spring cushion. These four rings are tied together by two small intersecting helical springs and (3 whose ends are fastened to the rings oi the main in any suitable way. 'ihe tie springs are interengaged by screwing one through the other. In order to pre vent relative displacement of the tie springs out of the plane containing them, and consequently the noises and damage resulting therefrom, the middle coil of one of the springs is provided with a notch or sent 7 to receive a coil 01 the other spring. This notch or seat is produced by making a sharp inward bend in the wire. I
henthe'twosprings are to be interengagcd. one end oil the spring 6 is screwed into the spring 5 at such a point that the wire of the spring (3 will enter the notch 7 instead of passing on the inner side ot' the spr'ng at that point as would be the case there were no notch. Then, after the interengagemcnt ot the springs has been completed, it will he found that one of the coils of the spring it rests in the notch in the other spring while the next coil bears against the inner side of the wire or the spring 5 near the notch, as best shown in Fig. 1-. Now, it the spring 6 tries to move up, the coil marked A in Fig. i will carry the spring 5 up with it. It the spring (3 ties to move down, the coil marked B in Fig. l, namely the one seated in the. notch oi the spring 5, pulls the other spring down. Theretora although the spring 5 may roll about the notch as a fulcrum, there can be no slipping up or down of either tie spring relatively to the other when assembled in the spring cushion.
Although only a single preferred form of the present invention has been illustrated and described, the invention is not limited to the exact structural details thus illustrated and described; but covers all forms and arrangements coming within the definitions of the invention constituting the appended claim.
What is claimed as new is:
Two interengaged crossed helical springs one of which has a peripheral notch in the wire thereof, the other spring having a coil outside of the wire of the first spring and seated in said notch and a second coil extending through the interior of the first spring and engagec'i with the wire of the latter near said notch.
In testimony whereof. I sign this specification.
LOUIS E. PITTONI.
