MATTRESS AND MATTRESS COVER Filed Jan. 2, 1932 2 Sheets-Sheet 2 latented Get. 24, 1933 PATENT OFFICE MATTRESS AND MATTRESS COVER Charles Lofman, Riverside, Ill., assignor to S. Kai-pen & Bros., Chicago, 111., a corporation of West Virginia Application January 2,

2 Claims.

This invention relates particularly to mattresses and to the manufacture thereof; and the primary object is to provide for improved tufting of mattresses with the tufting cord or tape concealed 5 from view.

The invention is illustrated in the accompanying drawings, in which- Figure 1 is a. broken sectional view of a mattress tufted in accordance with my invention; Fig. 2, a

sectional view in elevation similar to Fig. 1, showing diagrammatically the method of tying; Fig. 3, a broken plan view of the mattress; Fig. 4, a broken perspective view of the tie member secured to one side of the mattress casing; Fig. 5, a sectional view, the section being taken as indicated at line 5 of Fig. 4; Fig. 6, a perspective view of a tie member secured to an opposite side of the mattress casing; Fig. 'l, a view of the tie member shown in Fig. 4 being tied to the tie member shown in Fig. 6; and Fig. 8 shows the completion of the tying operation.

The invention is shown applied to a mattress having a filling which comprises a body of springs and layers of cotton or the like covering the springs. However, the invention may be used in connection with mattresses having any Suitable In the illustration given, A designates a filling comprising a spring structure A and layers of cotton or the like, A overthe spring structure,

and B designates a casing for the mattress.

The spring structure A shown is of the type in which coil springs are encased in fabric cells.

The casing B comprises a top cover 10 and bottom cover 11. The top and bottom co'vers, which cover the broad sides of the mattress, are connected with the bong or border 13 by means of corner seams 14. If desired, the boxing 13 may be reinforced with quilting etc. 15.

.Ey improved method of tufting mattresses comprises broadly the stitching oi tie members to opposite inner sides of the mattress casing, drawing one of the tie members, by means of a needle, through the body of the mattress and tying it to the other tie member.

in the illustration given, a tie member 16 is eyelet stitched to the top cover 10 in such a manner that a loop 17 is formed. As shown more clearly in Fig. e, the free ends of the tie member are brought together into overlapp relation and then secured by eyelet stitching to the cover 10. To the inner side of the bottom ooverll at a point opposite to tie member 16, I prefer to secure a tie member 18 of the shape shown more clearly in Fig. 6. The single strip of tape or cord is sewed,

1932. Serial No. 584,487

by eyelet stitching, at about its middle point to the inner side of bottom 11.

In the stitching operation, I prefer to use an eyelet-stitching machine devised. to accomplish the purpose and preferably a machine of the type described in my c'o-pending application,

. Serial No.- 525,750. While it is unnecessary to and tie member, as will be understood more 7 clearly from Fig. 5.

The tufting is accomplished, as illustrated more clearly in Figs. 2, 7 and 8, by thrusting a long needle 19 provided at its point with an .eye through which a portion of the loop 17 is passed, through 7 the filling or body of the mattress, while the mattress is under compression, passing the needle point through the two legs of tie member 18, withdrawing the needle to free loop'21 and then passing the ends 20 of tape 18 through the loop portion 21 of the member 16 which extends through the tape strips 18. A pull exerted upon the tie member 16 forms a secure knot, as illus= trated in Fig. 8.

In the tufting operation it is preferred to start near the center of the mattress and to work each way, the mattress body being placed under compression along the line where the tufts are being made.

By my improved method, I dispense with metal 99 eyelets and employ stitched eyelets which may be formed economically upon the imperiorated fabric, the selected points being simply marked in advance of the eyelet-stitching operation to insure a desired arrangement or pattern for the tufting. At the same time, the cords or tape used in the tufting operationare wholly concealed. The tufted mattress is sturdy and uniform in contour.

The foregoing detailed description is given for 1w clearness of understanding only, and no unnecessary limitations should be understood therefrom, but the appended claims should be construed as broadly as permissible, in view of the prior art.

I claim:

1. In the process of mattress manufacture, the steps which include securing a tie member in the form of a loop to the inner side oi the mattress casing, securing a strip of tape to the inner side of the casing opposite said first-mentioned tie 110 a strip of tape to the inner side of the casing opposite said first-mentioned tie member, forming a mattress body in said casing, tufting the mattress by steps which include thrusting a tufting needle carrying said first-mentioned tie memher through said mattress bodv and also through a free end portion of said tape, and looping the loop-end of said first-mentioned tie member which has passed through said end portion of said tape about the end of said tape member.
