MATTRESS OR THE LIKE Filed Jail. 10, 1944 Patented Dec. 23, 1947 MATTRESS OR THE LIKE Edwin L. Pabst, Cincinnati, Ohio, assignor to Spring-Air Company, Holland, Mich., a corporation of Michigan Application January 10, 1944, Serial No. 517,697

7 Claims.

The present invention relates to cushion pad structures such as mattresses and the like and comprises an improvement in the construction described and claimed in my copending United States patent application Serial No. 472,511, filed January 15, 1943, issued April 3, 1945, as Patent No. 2,373,047.

The structure to which the invention relates is the'type in which an outer casing, such as a mattress ticking, is compartmented by spaced parallel partition sheets extending between and secured to the top and bottom panel sheets, generally crosswise of the assembly, with resilient material such as cotton, hair, rubber or the like filling the compartments. Patent No. 2,373,047 describes and claims certain improvements in the relative arrangement of the outer casing and the inner partition sheets, and in the method of assembly. The present invention introduces further improvements which may be combined with those of the earlier application or may be used independently thereof.

Important objects of the present invention are to reduce the-cost of manufacture of cushion pads of the type indicated, to strengthen the construction, to render it more durable in use, and to eliminate puckering and unevenness in the newly made product as well as the tendency to become puckered and uneven due to stretching of the fabric after a period of use.

The foregoing and other objects and advantages will be apparent to those skilled in the art from the following specification, taken in conjunction with the appended drawing, in which I disclose a preferred form of embodiment of the invention. It is to be understood that this embodiment is selected merely to illustrate the invention in a form which I now prefer and have found eminently satisfactory in actual practice. This disclosure is not to be taken as limiting the inventive features to the precise form in which they are disclosed. On the contrary, these features are susceptible of modification within the broad spirit of the invention as defined by the appended claims; moreover the novel features need not be used in the combinations in which they are embodied in the illustrated form, since some of them are capable of independent use.

In the accompanying drawing,

Fig. 5 is a fragmentary perspective view of an assembly of top and bottom panel sheets showing the spaced relation in the finished product;

Fig. 6 is a cross sectional View of one side portion of a mattress showing the complete assembly of top and bottom panel sheets, a partition sheet and a side wall sheet; I

Fig. 7 is a similar view showing the side wall panel sheet and partition sheet connected in a different manner from that shown in Fig. 6;

Fig. 8 is a perspective view of a finished mattress; and

Fig. 9 is a detail cross sectional view taken on the line 9-9 of Fig. 8.

Referring now to the drawing, where the invention is shown disclosed in a bed mattress, Fig. 1 shows a panel sheet I0 which is rectangular in shape and made of any durable fabric as is usual in the making of mattress ticking. Two of these panel sheets are used, one for the top of the mattress and one for the bottom. The sheet In in Fig. 1 may be considered to be the top sheet and it differs from the corresponding sheet shown in my Patent No. 2,373,047 only by being about two inches longer for incorporation in a finished mattress of the same size as the one shown in that patent. This extra length is necessitated by the provision of spaced parallel tucks, preferably arranged transversely of the sheet, to provide attaching surfaces for compartment partition sheets as will now be described.

In Fig. 1 the numerals II, II indicate lines, which may be and preferably are imaginary lines, along which the sheet is folded to provide the tucks 12 (Figs. 4 and 5). The line I3 in Fig. 1 indicates the juncture of the two plies which constitute the tuck, this line appearing also in Fig. 5. It will be understood that Fig. 1 depicts the unfolded blank, while Fig. 2 shows the finished blank with the tucks incorporated in it by a line of stitching 14 at the base of each tuck, securing the two plies together.

Fig. 3 shows the finished sheet with the margins of the partition sheets I5 sewed by a lap seam to the flanges or ribs provided by the tucks [2. This connection is made by a line of stitching l6 spaced to be slightly inwardly of the line of stitching 14 which formed the tucking relationship of the two plies.

The tucked sheet will be found reduced from its originally eXCess length to the length of the desired mattress, the excess material being used in the tucks. The partition sheets are sewed to the tucks and the edges of the sheet are then sewed to end and side wall sheets l1, I8 respectively to form a finished box structure having compartments defined by adjacent partition sheetsaadapte ed to bestufied with any conventional filling. The end portions of the partition sheets l may be notched out, as shown at I9 and as disclosed in Patent No. 2,373,047, for the purposesthere. fully explained. When the mattress is filled'and sewed closed the product willfbeafoundttobeune. usually durable and substantial becausethe topand bottom panel sheets present no lines of surface stitching where the partition.-sheets -are,con-- nected to them. The connecting lines of stitching it are concealed within the structure; as best appears in Fig. 9, and being thus concealed they are protected from injury, The lines-oi stitching- [4 which fix the tucks are likewise concealedAvithin the structure so that they too, areprotected from damage. The assemblingoperation is-great. 1y facilitated because itis much' easieh tosowthe margins of the partition sheets; i5 tov the-ribs formed by the tucks l2;than to perform-thetype of sewing shown in this: part of; the. structure-as; disclosed in Patent No. 2, 3-733047, and, as previe ously practiced. Moreover; it. is; easierto; place properly the tucks in ablank flatrsheetzthanato. sew the partition sheetsalongstraightandequally' spaced parallel lines in a sheetoi:mattresatiching;.

In addition to the foregoing; advantages? the double plies of the tucks provide-strengthening: ribs which tend to maintainthe. mattress against; distortion resulting from stretching-oi the. mattress.

The structure is thus morereadily-made and is stronger and more durable in use than: any conventionally made prior; art device; with: which I am acquainted. Constructed ass. thus: far. (16:- scribed the invention obviouslyrhasconsiderable merit and novelty, but Iprefer to -intr,odnce-,c.er.-- tain further improvements which are; productive. of additional advantages; These; will; nowbeedee scribed.

I prefer to deepen the tucks; l2'galong'the-end. portions of each, i. e., along; the,v side: marginal: zones of the mattress, as .shown atpzfii'in -Eigs. 5 and 6. When the partition .ShBfilESJ fiiarenotched at their corners as is; preferred, thesed'eepened: or widened portions of the, tucksaextend-into the cut out areas Iii. They are-notuoined to the partition sheets, but they have the-efieots of'taking up excess material from/the. length-.ofrthe-panel' sheets so that the original overallzlength of theside marginal zones of the panelisheetsis less than that of the intermediate zone-thereof. I have attempted inFigs. 2 and 3 to'illustratetheefiect the stippling 2 I. The-arrangement permits a predetermined degree 'ofcrowning of the intermediate zone of each-panelsheet resulting from the fact that the partition; sheets. I;5 hold. the intermediate zone-down or inwardly of; the mattress. There is less crowning, or none at all; along the side marginal zonesof the mattress., where the material is notheld downorinwardly by the partition sheets. If. itwere-not for the deepened or widened tuck portions 20. in these. side marginal zones the panel. material. would. pucker. The material ishowever. kellhstrai h and fiat by the novel arrangementrofdeepening: the tucks because the excess material,,-,is;therebyr removed from the plane of the panel sheet and tucked inwardly of the structure.

The efiect is sought to be illustrated in Fig. 8, where it will be observed that the intermediate area of the mattress is well crowned as is desirable in these constructions, while the side marginal zones taper down to an edge which is quite flat and. straight. This formation of the edge adapts it to receive very neatly the side and end wall sheets which are conventionally secured in place by usual border trimming Or cording 22.

The .end.edges of each partition sheet l5 may be connected to the side wall sheets [8 in the conventional manner, as shownin Patent No. 2 ,373,04T and in. Fig; 6 of the present application. However; I prefer'tozmake this connection in the samegenerahway asthe connection between the side margins of the partition sheets l5 and the panelisheets ID, i. e., by the use of tucks. This arrangement is shown in Fig. 7, where it will be noted tucks 23 aresewed into eachside wall sheet laa with-widened or deepened endv portions and the, intermediate portions are stitched'to the end margins of the partition-sheets; By deepening: the end portions; puckering of r the. margins 'of the sidewall sheets is eliminated, andtheusev of tucks tional features or constructionsv for any utilitarian:

afiords a strong, durable and easily made connection for the partition sheets and. the: sidewall sheets.

The mattress maybe trimmed insany-desirablep Way. and. adoption of the'process of t-hepresent: invention, in thewhole combination or any part: of. it, will be found to be productive, of-the ad-- vantages hereinabove asserted and-tomilitate in no wayagainst the incorporation of any convenor. ornamental purposes.
