25 Claims.

This invention relates to improvements in mattresses and the like, and methods of producing them. By mattresses I wish to include all mattressing of like nature.

It is the primary object of the invention to provide by a novel method and construction a mattress or the like in which the tufting is wholly concealed within the ticking and is nevertheless connected not only to the padding but, with unusual strength and permanence, to the ticking itself.

In the preferred form of this invention the tufting is actually complete, independently of the ticking, but the strings or cords used in tufting have a supplemental anchorage to the ticking as a means of fastening it at intervals to the body of the mattress.

Other objects of the invention will appear from the following disclosure.

Figure 10 is a fragmentary detail view in perspective showing on an enlarged scale the manner in which the ends of the straps or ribbons used in the quilting operation according to this modified method, are anchored to the mattress carcass.

Like partsare identified by the same reference characters throughout the several views.

For the purposes of illustration I have shown a mattress body generically designated by reference character It, made up of an inner spring unit I, layers It of sisal on each face of the inner spring unit, and layers I! of felt or the like covering the sisal and padding the inner spring unit. The inner spring unit is provided with upper and lower wire frames l8 about which the layers l6 and I? of sisal and felt are rolled as shown in Fig. 4. In the completed mattress a strip of ticking I9 is applied about the sides and ends of the mattress body and connected by a taped seam along the edges thereof to the top and bottom ticking facing sheets 2i and 22 respectively. It is with the quilting which anchors the various plies of the mattress in between the margins thereof, that this application is particularly concerned.

Both of the methods herein disclosed involve the preliminary application to the top and bottom ticking sheets 2| and 22 of 'a series of transversely extending straps 25 which are folded upon themselves about an ordinary heavy string or cord 26 as best shown in Figs. 4 and 6. The ends of the cord 26 are turned over and sewed at 2'! to the strap 25 either in connection with the attachment of the folded strap to the ticking sheet, or any other tie with reference to such attachment. A single seam 23 close to the cord may be used to sew each of the folded straps 25 throughout its length to the inner face of the ticking sheet 2i (or 22 as the case may be).

According to the method disclosed in Figs. 1 to 7, additional steps involve the top ply of ticking 2| prior to its application to the mattress body. The quilting ties which comprise a single piece of string or cord 29 as shown in Fig. 7, are looped upon themselves at 30 to form two strands which are then knotted at 3| to leave free ends 32 and 33. The looped end 30 of each of the ties 29 is passed through a quilting needle 34 and drawn through one of the straps 25 around the cord 2% therein contained at the point where quilting is desired. In Fig. 5, at one point of the second strap 25 the needle 34 is shown penev a time.

the next station the tie has been pulled tight about the bight of the strap 25 and the cord 26 therein contained, thus leaving this final tie in the same condition :as all of the ties which have theretofore been applied to the first strap of the ticking ply 25.

The same operation is repeated for the successive straps until each strap is provided at predetermined stations with a series of preformed ties each of which has a predetermined length from the strap to its knot at 31, as best shown in Figs. 5 and 6. l

The ticking is now ready for application to the mattress body. The body is temporarily placed on a ply M of burlap as shown in Fig. l and Fig. 2. The free ends of the tie 32 and 33, of the knot 3| are now inserted through the eye of the needle and the needle is used to draw the free end portions and the knotted end of each tie in succession through the entire body of the mattress as shown in Fig. 2. The needle is passed down through the body of the mattress and through the burlap ply 49, the function of the burlap ply being frictionally to retain the ends of the ties until the second ticking ply can be positioned.

When all of the several ties originally mounted .on the top ticking ply have been passed through the body of the mattress in this manner, the

top ticking ply is held to the body of the mattress solely by friction of the ties in the mattress body and, more particularly, in a temporary burlap facing. The mattress body is now inverted to bring the temporary burlap facing uppermost and the other ticking ply 22 is thereupon attached as follows:

The burlap is stripped from one row of ties at This will leave the free ends 32 and 33 of each tie exposed. One of these ends will be inserted in the eye of the needle and the needle will thereupon be used to draw this single free end through the adjacent strap of the bottom ticking ply 22 and about the cord 26 therein contained. Considerable tension will have to be exerted since the quilting operation is actually performed at this time to subject the body of the mattress to compression.

As soon as theend 33 has been drawn through to bring the knot 3| up against the strap 25, the

ventional operation of making the seams 241 along its upper and lower margins.

According to the operation shown in Figs. 8 to 10, which from many standpoints is to be preferred, the quilting of the body of the mattress is complete independently of the top and bottom layers of ticking.

The mattress body It may be made in any desired manner as, for example, that already described. The top and bottom plies 2| and 22 are likewise identical to those already described, even including the provision of the straps 25 folded about the reinforcing cords 26 and stitched by a seam 28 preliminarily to the facing sheets 2| and 22 of ticking. It will, of course, be understood that the straps 25 are preferably narrow strips of fabric. Tape may be used or the strips 25 may be made of trimmings saved from the fabric cutting operations involved in mattress manufacture.

Before either of the ticking faces 2| or 22 is applied to the mattress body, the ties 290 are first drawn completely through the body. It is not necessary in this method of procedure to employ the temporary burlap ply, As before, the ties are of predetermined length but in this instance each tie is preferably made from two separate cords 29| and 292 knotted together at 3H] and 3H, there being a fixed distance between these knots. The short ends of the tie projecting at 5520 and 333 are virtually identical to those already described. In addition, the tie preferably has longer end portions at 32! and 33!.

The long ends 32l and 33l of the respective ties are placed in the eye of the quilting needle 34 and drawn through the body l0 until the knot 3H] is drawn down on to the top surface of the mattress body. After all of the ties are in place on the mattress body, the ties of a given row are pulled slightly upwardly of the body sufficiently to raise the knots 3| I! from the upper surface of the body and to permit a loose tape or strap 2% to be passed between the cords Hi and 292 and beneath the knot 3W. The final step of this operation is shown at the lower right in Fig. 8. When the tape or strap 250 is in place its ends ma either be left free as shown in Fig. 8, or they may be carried about the roll of felt at the side of the mattress and stitched through the felt to the frame 68 of the spring unit as shown in Fig. 10.

In either case the mattress will now be inverted and tapes or straps inserted in like manner on its opposite face.

The spacing between the knots 3H] and 3 is So determined with reference to the thickness of the mattress body as to require a substantial compression of the mattress body to expose the knot 35 I for the drawing of a tape therebeneath. The operator simply compresses the mattress body with one hand, pulling up on the free end portions 32! and 33l of the tie with the other hand until the knot is lifted above the face of the body, whereupon he can draw the tape or strap 25% beneath the knot and release his compression of the body to enable the bodys recoil to bind the strap or tape firmly beneath the knot. This operation is repeated at each station until the bottom of the body, like the top, is traversed by a series of tapes or straps each of which is held beneath a knot of the tie so that the body portion of the mattress is bound together and fully quilted before either of the ticking plies is connected thereto.

The operation of connecting the ticking plies is now identical with the operation of applying the last ply to the mattress in accordance with the previously described method. It will be recalled that each of the plies has previously been supplied with straps 25 folded about reinforcing cords and stitched to the ticking. The needle is used to draw one of the exposed free ends of a iven tie through the strap and about the reinforcing cord at each station, whereupon the other free end of the tie is used to make a knot with the first free end and this knot is drawn up tightly upon the folded strap and its unfolded reinforcing cord to unite the ticking sheet permanently to the mattress body at each station.

The arrangement by which the reinforcing cord 26 is folded into the bight of the folded strap '25 and stitched continuously throughout its length to a transverse dimension of the ticking distributes the strain involved in the quilting and ensures a long life for the mattress. At the sametiine the fact that each tie is passed through the strap positions the end o'fthe tie accurately at the predetermined station and makes any lateral shifting of the quilting impossible. This last feature is, of course, not present in the prequilted body shown in Fig. 8 until both of the ticking plies have been attached as shown in Fig. 9.

An important advantage of the invention as herein disclosed consists in the factthat it not only makes a neat product in which all the knots used in quilting are concealed beneath the ticking but, moreover, the operation may readily be performed without special mattress making machinery or equipment, thus making it as easy and inexpensive for the small manufacturer to produce this type of mattress as it is for the large manufacturer to do so.
