Application filed May 10, 1926 Serial No." 107,891.,

This invention relates to mattress ventilators, and more particular to ventilators for mattresses, cushions and the like, the covers or ticks of which are provided with a numher ,of-openlngs there n, through which an may circulate to the interior of the m tress or cushion;

The objects of the invent-ionv are to provide means for preventing the mattress lilling from coming out through the holes-in the tick which means will. permit free cir-' culation of air therethrough, and which will be simple and economic to make, of rigid construction, and which will. be provided with means for attachment to the mattress tickwhereby it will not readily or accidentally be'pulled therefrom.

Other objects and advantages of the .invention willbecome apparentwhen the following specification is considered in connection with the accompanying drawing wherein I have illustrated a selected eir-- bodimentof the invention, and in which:

Fig. 1 is a plan showing a ventilator according to the present invention, in piace on a mattress tick. I

Figs. 2 and '3 are sections whichillustrate successive steps in the construction. of the'ventilator, and Fig. 4 is a sectionon the line 1- of Fig. 1, and illustrates the method of fasten ing the ventilator to the tick.

Referring now to the drawings, and'more particularly to Figs. 1 and 4, aventilator according to the present invention is indicated at 5, secured to a mattresstick or cushion covering 6. The ventilator 5 comprises a metal tube Thaving a reticulated closure portion 6 extending thereacross, and

provided with an outwardly extending flange 7 against which the edges of the'mats tress tick, around an. aperture therein through which the ventilator passes, is adapted to be clamped or pinched by means of another flange '8.

The construction and application of the ventilator is as follows: The first operation is to form a cup such as shown in Fig. 2. .This cup is provided with a tubular portion 9 and an end closure 10 which is preferably recessed as shown. The second operation is to punch suitable holes 11 in the recessed end closure 10 as indicated in Fig. 3. The next operation is to swage the tubular portion 9.inwardly into the form shown in portion 13.

Fig. 3 to provide a shoulder 12, and anupwardly extending tubular portion .13. The

ventilator is then projected through the said aperture i l-until the mattress tick rests on the shoulder 12 as shown in dotted lines in Fig. '3. t tion ofthe tick 15 immediately adjacent the aperture will be forced to turn upwardly or outwardly with the projectingtubularportion 13 and will be caused to lie thereagainst and this yi reason of the greater diameter of the tubular portion 13, as compared with the diameter of the aperture 1 1.

The ventilatoris secured in position on the; mattress tick by turning the projecting tubu-' lar portion .13 outwardly over the shoulder 12 whereby the portion 150i the tick will be folded upon the adjoining portion ofthe tick seas to provide :a double edge around against the marginal portion of the closure member 6 so as to form the flange 7 of double thickness without any intervening space whereby the' finished flange 7 is of double thickness but is nevertheless comparatively thin, and therefore will not project beyond the tick to an objectionable degree.

By causing the edge'of the tick adjacent the aperture to be folded upon itself, so as to provide a double thickness edge around the aperture, the ventilator is afforded a re-. iniorced edge on which it may be clamped, By this means the possibility of accidental or easy pulling out of the ventilator is largelyeliminated as it will be obvious that the said double edge will not readily tear or pull out from between the flanges 8 and 12. I have thus provided a ventilator constructed of one piece which may be easily and eco- Jioijrs cor/teen or mattress tick 6, to which theventilator is i The tubular 'portion 13 01. the

will be observed that apor so a nomically manufactured and secured in construction and proportion or parts may bemade Without departing from the essence of the invention, and I therefore reserve the right to make such changes as fall Within the scope vof the following claim;

I claim as my invention: In a ventilated mattress, the combinatlon of a tick portion having an aperture therein,

'a tubular member having a reticulated'closure member extending thereacross, said tubular member being of greateroutside size than V the size of saidv aperture and being-adapted to be inserted into said aperture so as to project therethrougl'n whereby a portion of said tick adjacent said apertureivvi'll be caused swaged portion.

to lie along said tubular member, a shoulder V at one end of said tubular memberfor positioning thelatter With respect to said tick, said projecting portion ofsaid tubular member being adapted to'be swaged outwardly and towards said shoulder so as to effectively clamp the tick surrounding said aperture between said shoulder and the swaged p0raperture and between said shoulder FRANK KUSTERLE.
