2 Claims.

the mattress or cushion at intervals in order to prevent spreading of the material and also serves as a ventilator.

The ventilation of a mattress or cushion is desirable for keeping the article more sanitary but also because it aerates the filling thus keeping it resilient and also adding to the resiliency by aiding the passage of air into and out of the inside of the mattress or cushion.

The present invention has for its object the provision of a tuft which is easily and quickly applied, that enables a ready tufting of the article and also serves as a ventilator for the article.

The invention is illustrated in the accompanying drawing in which Figure l is a central section of a tuft placed in a mattress, with a section of part of the mattress to illustrate the application of the tuft. Figure 2 is a top view of the tuft and mattress shown in Figure 1. Figure 3 is a side view of the tuft shown in Figures 1 and 2. Figure 4 is a top view and Figure 5 is a central section of a tuft of modified form. Figure 6 is a section and Figure '7 is a top view of a tuft of still another modified form attached to the mattress.

The tuft may be made of any desired shape and thickness within the requirements of tufting mattresses, cushions, seats and other padded articles which are included within the term mattress as r used in this specification.

The form shown in Figure 1 comprises a disk 10 with perforations 11 to allow the passage of air. The disk is provided with fastening means, as prongs 12, struck up from the material and bent down at the edges of the disk. The prongs 12 are later bent over as shown in Figure 1 and Figure 2 to fasten the tuft in place. It is desirable to perforate the mattress cover 13 as shown at 14. The tuft is then applied as shown in Figure 3 and then fastened as in Figure 2 by bending over the prongs 12 on the under side of the cover. The tuft is provided with means to draw it against the mattress for the purpose of tufting. In Figures 1 and 2, we show the openings 15 which are in this case larger than the holes 11. The openings 15 are large enough to receive the cord 16 used for tufting. In the drawing we show two holes 15 with the tufting cord passing through both although the cord may be knotted. The disk is strong enough to resist the tufting strain without substantial distortion. The assembled parts provide a well-ventilated mattress.

In Figures 4 and 5, we show a flat disk 17 with openings 18 for the tufting cord and slits or openings 19. This form is shown without prongs or fastening means as the tufting is done over the mattress cover without making any opening in cover before tufting.

After the tufting is completed a knife blade can be inserted through the slits 19 and cuts made in the mattress cover.

In Figures 6 and 7, we show a tuft of the eyelet type with the eyelet portion 20 having its lower edge 21 crimped over the edge of the opening in the mattress cover. The eyelet portion has the annular groove 22 in which is held the screen 23 and suitable means for resisting the tufting strain. The means shown consists of a relatively stiif strip 24 provided with means such as the holes 25 for receiving the cord 16.

Aerated mattresses are more resilient than closed mattresses due to the lack of confinement of the enclosed air. Such mattresses last longer than those not ventilated as the hair or other filling does not mat so quickly due to the air to which it is subjected. The present invention provides a single means for tufting and. for ventilation and there is no additional work beyond tufting necessary.

Various changes can be made in the manner of fastening the tuft in place and in the form and proportion of parts without departing from the scope of our invention.

We claim:

1. A tuft comprising a disk having openings therein for ventilation and additional larger openings for a tufting cord and having prongs extending from the disk for securing the tuft to the cover of the mattress, the disk having sufficient rigidity to withstand the tufting strain.

2. A tuft comprising a disk of rigid material, the disk having openings distributed over its area and having prongs extending from its periphery for securing it to the cover of a mattress, at least one of said openings being large enough to receive a tufting cord, the other openings being relatively small to provide ventilation.
