` vsuch a manner as to preventlateral stretch-v mg. f Y n It is well known that the ordinary mattress formed of theI 'so-called cotton felting or layers of cotton batts,\ evenwhen secured in\-the ticking will stretch sidewise and `lengthwise and therefore making the mat" tress unshapely-as-well as causing a variation in the thickness at different places, making an uncomfortable mattress.

In my 'invention' I `build the mattress up with a plurality of layers of cotton batts and as an upper Ylayer is applied to the lower layer I put an interlayer of cheesel cloth, coating the cloth with -b'ands of soft glue,

. 2 thus causing the cotton of the batts on opposite sides of the cheese cloth to adhere to the cloth and hence to bind one with the other. The succeeding layers. are built up in the same way, alternating layers of batts and cheese cloth and preferably lham'ring'no cover-- ing on the top or bottom of .the uppermost and lowermost batt. As an eXtra precau-4 tion strings are threaded through the mattress so formed from top to bottom and each string is knotted on the outer surface of the .exposed batts. The usual ticking is then drawn overl the mattress so formed and pref-- erably has a beadingor roll at the edges but is not bound through the mattress with tuft-v ing strings or the like but is preferably left with a-smooth upper and lower surface.

, My inventionv as to the mattress and\ the method of making will be more'readily un` derstoodfrom the following description and 40 drawings, in which; 1 A

I n the drawings, the individual batts are deslgnated by the numerall and for purposes of description the ends may be designated as the head and foot 2, the sides 3 the top 4 and the bottom 5. In Figure 1 the f hrst step is indicated by forming cross bands vorstrl/ps 6 'of soft glue and longitudinal strlps' of soft glue. This is preferably poured on the batt by utilizin a container having a spout with a smal orifice and quickly passing the oriiice above the batt j in close relation thereto, pouring a small quantity of glue on the batt.

The next step is to place a layer of cheese cloth 8 on' the top of the batt before the glu e has an opportunity to harden and then strips of glue 9 andflOvdesignating the cross strips and longitudinal-strips are poured on the cheese cloth following the lines of the bands or strips 6 and 7 on the batt underneath. This efectually binds the cheese cloth to the batt on which it' is spreads The third ste-p is to place the secondbatt designated by the letter B on top of the rst batt A before the glue on the cheese cloth has hada chance to set.

A layer of ycheese cloth is then placed on top of the batt B after it has been striped with glue as above described. The layer of cheese clotlrj'and the succeeding batt are ap# ve layers of batts -shown with four layers ,of cheese cloth in between, the batts being designated by the letters A, B, C, D and E, and the layers of'cheese cloth being designated by theletters a, b, c, and d. The bottom surface'of the lowermost batt and the upper surface 4, of the topmost batt are not but left in their natural condition, j A* A further step is illustrated in Fi 4, in which the mattress asabove" formedliy utivlli'zing alternate layers of cheese cloth and batts with the striping .of glue' to bind them rtogether, are stitched with string or 'thread Av10', formingmerely a straight stitch through the mattress from the top to the bottom and tying the string at each end' close intothe liti tltl

bett. Preferably l do not use any tufting leathers or other devices to sprend the pressure on the adjacent parts of the butts es` With my construction simplehund tied lrnots 1l are suilicient.

After the mattress is medeup as ebove described the cover or ticking ll which is of the usual character is placed over the mattress in the usual manner und stitched to form a covering. The top and bottom l2 of the mattress is preferably left plein and smooth Without any tufting by u stitching through the mattress us with my construction it is not necessary as the munner of building up the batts prevents luterul stretching. lhe edges 13 are formed in the usuel munner With the usuel roll ld ut the upper und lower corners thereof around the mattress.

'lhe procedure outlined may be simplified if desired by omittingr the first step of strip ing' the lon'ermost butt with glue es the cheese cloth 'een be spread over the butt und the @glue will pass through the cheese cloth sufficient to bind the butt and the cheese cloth together, the Second bett beingF placed on the cheese cloth before the leb'lue has hud un opportunity to harden. rl`he whole mattress may be built up in `this fushion if desired.

ltlor some types of mattresses the last step of forming the tufting" by utilizing the strings l0 With the knots lil muy be omitted as for most purposes the alternute loyers of butts and cheese cloth with the glue stripinpgs is sufficient.

llt is obvious thut my invention may be applied to diil'erent purposes other thun melting cotton mattresses, for instance the same principle may be applied to building; up luyers of felted materiel, one on top of the other. tlso for some purposes the layer of cheese cloth may be omitted, the different batts being' Well striped with glue before they ere placed one on top of the other.

Again for other types of mattresses the i retener glue und cheese cloth muy both be omitted und the mattress constructed b tuftine' the mattress as shown in Fig. l With the nots bearing directly on the material of the batt. Other modifications of my invention Without departing from the spirit thereof will be apparent.

Having described my invention, what I claim is:

l. The method of making mattresses comprising plnoing a sheet of open mesh fabric on the surface of :t batt, coating the fabric with glue, allowing some of the glue to run through the meshes, placing; u second layer of butt on the fubrc before the glue is set and building up a mattress with alternate layers of batts and febric with the glue cont ings on the fnbric.

2. Vlhe method ofunalring mattresses comprising' placing; u sheet of open mesh fabric on u batt, striping; the fabric with strips or bends of glue, allowing the glue to permeate through the meshes und applying e second layer of batt to the fabric before the glue is set and building' up a. mattress with the desired number of alternate luycrs of butts end fubric.

3. 'lhe method of melting mattresses comprisinggF stripingI the surfuce of a, batt with stripes or bends of glue, placing u sheet of open mesh fabric thereon, striping the fabric 1with stripes or bands of glue and applying a second batt on topI of the fabric before the glue is set end buildingI up the mattress to the desired thickness With alternate layers of bat-ts und fabric, striping the batt and then the fabric laid thereon, with glue.

it. mettress built up of alternate layers of butts and sheets of open mesh fubric with stripings of glue, bindingr the fabric to the butts on both sides thereof und e ticking cover on the mattress having smooth top und bottom surfaces without tufting.

ltn testimony whereof l have signed my neme to this specification.
