Patented Oct. 11, 1932 UNITED STATES PATENT OFFICE WALTER KIWI, OF ANDALUSIA, PENNSYLVANIA, ASSIGNOR TO' PEERLESS SPRINGS,

INCORPORATED, OF WEST CHESTER, PENNSYLVANIA, A CORPORATION OF PENN- SYLVANIA SPRING CONSTRUCTION Application filed January 9, 1930. Serial No. 419,528.

This invention relates to bed bottoms, bed springs, automobile cushions, and the like, and has more particular relation to the pro vision of a device of the character stated in reducing the cost of extra clips and added expense of attachment.

A further object of the present invention is to provide a device of the character stated in which inherent flexibility is maintained to provide for maximum bending or folding of respective coils one with respect to another.

tion is to reduce manufacturing costs and provide for general flexibility in a bed bottom.

Other and further objects of the present invention reside in the provision of general details of construction and arrangement and combination and connection of parts for attaining the results sought by the foregoing objects.

struction hereinafter described and finally claimed.

The nature, characteristic features and scope of the invention will be more fully understood from the following description taken in connection with the accompanying drawings forming part hereof, and in which: Fig. 1 is a top or plan View of a section of a spring mattress embodying the invention. Fig. 2 is a view in side elevation of Fig. 1. Fig. 3 is a fragmentary View in plan illustrating details of construction as shown in Fig. 1.

Fig. 4 is a top or plan view of a section of a spring mattress embodying a slightly different form.

Fig. 5 is a view in perspective of the means of connecting the parts shown in Fig. 4.

Fig. 6 is a view in section of the parts 53 shown in Fig. 5, taken on the line 6-6.

A still further object of the present inven- The invention consists of the novel con-' Fig. 7 is a top or plan view of a section of a spring mattress embodying still another form of connection.

Fig. 8 is a View in perspective illustrating the connection of parts shown inFig. 7

For the purpose of illustrating my invention I have shown in the accompanying drawings several forms thereof which are at present preferred by me, since the same have been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of Which my invention consists can be variously arrange'd'and organized and that my invention is not limited to the precise arrangement and organization of the instrumentalities as herein show and described. v

Taking up now the drawings in detail,

. and "referring first more particularly to Figs.

1 to 3, there is disclosed'a longitudinal strip of coiled springs 10. By the particular arrangement shown I am enabled to construct a spring-mattress, or mattress and bolster combined, composed entirely of metal springs, so that they may be securely. and

' firmly attached to each other to form a soft,

elastic, light, and noiseless mattress, or mattress and bolster combined, that may be used either side up, rolled together or bent in any desired shape to form a bed,and that it may be readily repaired or new springs inserted. The springs 10, as shown in Figs. 1, 2, and 3, I attach together by the winding together of the spring ends at 11. In other words, the material from which the springs are made is employed in making the attachment best seen in Fig. 3. Referring now more particularly to Fig. 3, a coil of spring wire 10 is twisted or wrapped with respect to an adjacent coil 10 to provide a connection substantially as shown at 12. This method assists in providing the following advantages:

By the above described arrangement and combination of parts I am enabled to construct a spring-mattress, or mattress and bolster combined, composed entirely of metal springs, so that they may be securely and firmly attached to each other to form a soft,

elastic, light, and noiseless mattress, or mattress and bolster combined, that may be used either side up, rolled together or bent in any desired shape to form a bed, and that it may be readily repaired or new springs inserted.

Referring now to the construction shown in Figs. 4, 5, and 6, a coil of spring wire instead of. beingtwisted or wrapped with respect toian adjacent coil has "hooked relation therewith. Referring now especially to Fig. 5, the spring wire 13 has formed integral therewithaloop 14, arranged to have cooperative'relation with which is a hook 15, formed integral with the spring wire 16 and doubled over upon itself as best seen in Fig. 5 in perspective to provide a double thickness. This forms a verycheap and efficient connection in-which no auxiliary fastening medium is necessary. Obviously, theabove described arrangement of coil spring attachmentmay be embodied inparallel rows in desired number. Thesevparallel rows may be secured together with the same spring wire material so that no auxiliary clips are required.

1 In Figs. 7 and 8 a coil of spring wire 17 has one end 18'thereof turned inwardly and then outwardly to form the hook-like part 19. This part19 is secured around an ad- ,jacent coil so that no fastening mediums not formed integral with the spring structure is employed. 7

What I claim is:

A self supporting spring cushion or mat of the character stated comprising aligned, spiral springs the upper and lower adjacent coils of'which overlap longitudinally and laterally considered, the end of the-upper last coil oit' one springbeing twisted both right and. left hand serpentine-fashion completely around the end of the upper last. coil of a companion spring both longitudinally and laterally considered, and the end of the lower last co il being similarly secured with respect to the end ofxits companion spring by the juncture of said twisted portions, each twisted portion forming a substantially diamond-shaped connection.

WALTER KIWI.
