This invention relates to improvements vin auxiliary pads for mattresses and to the method of assembly of said pads duri-ng the manufacture thereof.

With the development of foam rubber it was found that a sleeping surface made from the rubber has very desirable qualities, these properties not being available in any other' prior known material. l Y

However, in designing mattresses of foam rubber, several difliculties or limitations have become apparent. In mattress design,` a thickness of six to eight inches has been generally found most des-irable and bed constructions and bed heights are set accordingly. A body of roam rubber of that thickness has beenfoundto be unstable and to deform Yto a greater degree than desirable. If the body of the mattress is braced or trussed to overcome this disadvantage, proper action of the rubber isimpeded or prevented, since the foam rubber depends uponi whatis known as breathing for proper action. This vconsists in the absorption and expulsion of air by the pores of the rubber as pressure is exerted on or released from the body of the rubber. A further problem of the use of foam rubber informing a sleeping surface is that the rubber has extremely low tensile strength and is easily ruptured lif stretched or distorted beyond a critical point, and this critical point is easily reached in normal use. Thus, 1t is necessary, i-n forming a pad from a body of` foam rubber, to devise a method of tufting said body wherein the rubber is constrained against extreme distortion while at the same time avoiding any undesirable compression of' the rubber body except that caused by compression from use. It is to beemphasized that the rubber is of such softness that some compression may be caused by only moderate pressure of a tying or tufting tape. A

It is an object of the present invention to provide an auxiliary pad for mattresses by means of which any vstandard mattress may be given the sleeping qualities of foam rubber while at the same time use is made of the thickness or height of such standard innerspring or felt mattress.v

It is a further object of the present invention to provide an auxiliary pad for mattresses which may be readily attached to any type oi mattress and as quickly detached therefrom.

Still another object of the invention is I'to provide a means of covering a foam rubber auxiliary mattress pad and securely attaching it to a mattress so as to prevent slipping and displace- .ment of the pad during handling and use of the mattress.

i scams. (o1. 5454);-

A further-object,v of the invention is to provide anattachable pad -for mattresses with tufting so designedmthat the smooth sleeping surface of the pad may be maintianed without undesirable 1rtortionor pre-compressionof the foam rubber Another object of the invention is to/provide an attachable mattress pad so formed that the strain placed on the body of the pad by the securing tapes isv distributed over said pad .at spaced points,- reducing Wear on the elements and localized failure, and particularly preventing tearing of theV foam rubber filler due to distortion from use.

A further object ofthe invention is to provide a pad so designed that the tufting tapes may be exactly and individually adjusted so as to constrain the foam rubber filler without: pre-,com-

pression thereof. Y Still another object of the invention is'to pro,- vide a novel and improved method of assembly of the various elements of lthe pad, resulting :in a simplied assembly process and reduced manufacturing costs. l

With the above and other objects in view, as

will be presently apparent, the invention consists in general of certain novel details of construction and combinations of parts hereinafter fully described,` illustrated in the accompanying drawings and particularly claimed.v

In the accompanying drawings, like characters of reference indicate like parts in the several views, and

and in the type of the foam rubber filler shown herein, the lower face of the block is provided with a plurality of shallow, rectangular pockets.

The foam rubber filler has a surrounding cover envelope of any desired material. The lower wall of said envelope is formed of a lowerv panel I2 which is slightly larger than the rubber ller II. Running transversely of the lower panel I2 are any number of elongated securing tapes I3, these tapes being 'fastened to the panel by a single longitudinal row of stitching I4 and of such length that they will extend on either side of the panel and complete encirclement of a mattress to which the pad is attached and permit the outer ends being tied as shown in Figure 5, In the preferred form of the invention the stitching I4 is interrupted at spaced intervals to form the loops I5 which permit passage of the tufting 'tapes which are later to be described. In theA form of the invention as shown in Figure 6, the stitching Ila is unbrokenfor the length of thepanel.Y

yThe cover is completed by a top panel I6 which is slightly larger than the lower panel I2, so thatvit may be turned downwardly on allvfour sides to form the side walls Il. The two panels are joined at their peripheral edges in any desired manner. preferably by the stitching I8. Y,

On the inside face of the top panel I 6 and runningV transversely thereof are the tapes I9, these tapes directly overlying the corresponding securing tapes I3 on the lower panel I2. -These tapes I9 terminate slightly inwardly ofthe peripheral edge of the top panel I6 and are secured preferably by a single, elongated row of stitching 20.

.Running transversely of the tapes I 9v and lying between the tapes I9) and top panel IE are a plurality 'of spaced tufting tapes 2I. In the -preferred form of the invention the spacing of these tufting tapes 2I along the tapes I9 correspondsto the position of spaced loops I5 in the securing tapes ..I3. These tufting tapes Y are placed ben'eaththe tape I9 prior to the stitching thereof to theJtop panel I6 and are held at approximately their midpoint by the elongated rowof stitching 20, forming

outer legs

22 and 23. It is thus seen that the tufting tapes 2I and upper transverse tapes I9 aresecured by a single operation.V

In the preferred form of the invention the method of assembly of the mattress pad is as' follows: The rubberller II is.' centered'upon the lower panel I2, and the upper panell I6 in turned placed upon the filler, so that the tufting tapes 2l overlie the loops I5. By means of a suit# able instrument, the ends 22 and 23fof the tuftingtapes 2I are pushedthrough the porous Vrubber filler. The end 2I of each tape is then drawn through the loop I 5 and the exact tension placed thereon, the ends 2I and 22 then being tied in any suitable knot. It will thusbe seen that each tufting point is individually-and fixedly set at the exact tension,' andV withoutl any possibility of the strain being shifted or distributedunequally to other points. It will also be seen that the tufting is applied entirely from the interior faces of the upper and lower panels without any evidence thereof appearing on the outside. The tufting is completed row by row, and the four outer edges of the two panels are then secured bythe stitching I8. The pad I Il is then ready for application to a mattress M as shown in In the modified form of the invention shown in Figure 6, the securing tapes Haare fastened to the lower panel I2a by an uninterrupted row of stitching I 4a. After the legs 22and'23. are

drawn through the rubber filler II, the leg 23 is then drawn by a suitable tool, such as an upholstery needle, directly through the loose edges of the tape I3a, and the

ends

22 and 23 are tensioned and tied as before described. This form of the invention simplifies the manufacturing process by elimination of the need of measuring and providing for the spaced loops, and results in lower manufacturing costs.

While there is herein shown and described the preferred embodiment of the invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.
