7 Claims. (Cl. 5-347) The present invention relates to mattresses and has for its main object the provision of Ventilating means whereby the mattress, including the felt thereof, may be periodically aerated and deodorized by means of a suction or blowing engendered by a Vacuum machine.
Another object of the present invention is the provi- "t sion of an opening at the side edge of mattress casing, normally covered by a fabric or a perforated flap, and through which opening the nozzle of an air tube connected with a vacuum machine may be inserted after pushing the ap inwardly of the mattress by the nozzle.
Another object of the present invention is the provision of a suitable frame for engaging the edge of the mattress casing adjacent the opening made therein, through which frame a nozzle of a vacuum machine may be inserted into the mattress casing for drawing air by suction from the mattress casing or blowing air into it in order to aerate, dry and deodorize the mattress.
A still further object of the present invention is the provision of a screen fiap hingedly mounted and supported upon the frame aforesaid, with the mechanism for maintaining said ap in a closed relation with the opening bordered by said frame for the purpose of normally maintaining the said opening closed for thereby preventing any dust or insects reaching or settling inside of the mattress.
Another object of the present invention is the provision of a perforated tube suitably supported by one of its ends by the frame aforesaid and having its body suitably supported by the mattress springs, so that when suction or blowing is engendered within said frame the air would be withdrawn from or supplied to the farthest points removed from said frame.
With the above general objects in view and others that will appear as the invention is better understood,
the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawing and pointed out in the appended claims.

The mattress with which the present invention is adapted to cooperate is usually made in the form of a rectangular casing which is made of cloth. Usually three cloth layers, namely, inner fabric 16, the middle padding 17, and outer prefabricated binding 18, in a superimposed mutual relation, are used in the manufacture of a mattress, as is shown in Fig. 2. For the sake of clarity the mattress casing in other igures is shown as if though made of one sheet of cloth, and will hereinafter be referred to as mattress casing 18.
Referring to the most simple form of the invention illustrated in Figs. 1 and 2, the side of mattress casing 18 is provided with an oblong opening 19, having arcuate ends. In order to stiffen the marginal body portion of mattress casing 18 adjacent said opening 19, washer 20, conforming in contour to the contour of said opening i9, is superimposed upon the marginal body portion of casing 18, adjacent said opening. Thereupon an overand-over stitch 21 is made by thread and needle around said washer 2t) and the marginal body portion of casing 18 covered by said washer 20, as is clearly seen in Fig. 2. Thus said stitching 2l with the body portion of casing 18, adjacent said opening 19, and said washer 20, enclosed therewithin, constitute a frame which encloses said opening i9, and which provides stiifening of the mattress material adjacent said opening, and of course prevents fraying of the material.
A pair of flaps 22 are provided for interchangeably acting in connection with said opening 19 for providing a curtain therefor so as to prevent any dust entering the mattress casing through said opening 19. One of said iiaps 22 is sewn by stitches 23 to casing material i8 adjacent one longer edge of said frame 2l, while the other of said flaps 22 is attached by stitches 24 to said casing material 18, adjacent the opposite longer edge of said frame. When the mattress is laid upon a bed by one of itsrfaces, one of said flaps 22 will cover opening 19, while the remaining ap 22 will hang downwardly and out of the path of said opening 19. When the mattress is turned so as to lie upon a bed by its opposite face, then said latter flap 22 will drop down in the path of said opening 19, while the first mentioned tiap will hang down and out of the path of said opening i9. By this arrangement one or the other ilap 22 will at all times act as a curtain for said opening 19, regardless as to which face is in contact with the bed springs, as is clearly seen in Fig. 2.
Opening 19 is preferably of a contour corresponding to the contour of a nozzle of an air pipe which connects with a vacuum machine, in order that when said nozrle is` inserted within said opening i9 it substantially fills the Y same. In that manner when either suction or pressure is engendered in a vacuum wmachine no air escapes through the opening and past thesaid nozzle, in order that a full force may act upon the mattress fabric l5 or all of the multiple ylayers thereof in order to aerate, dehydrate and deodorize the same in a most etiicient manner.
Referring now to the more advanced form of the present invention, illustrated in Figs. 3 to 8, inclusive, the frame for opening 19 made in the mattress casing, is preferably made out of sheet metal or plastic. Said frame includes arcuate lip or bead 25, which, in the operative association of the frame with the mattress casing, will contact and bear against the outer face of said casing. ln the pre-formed condition or" the frame, the same includes extension 26, which is integrally formed with said bead 25 on its inner edge. Said extension 26 is provided with a plurality kof slots 27, which deline a plurality of prongs 23. When said bead is superimposed upon the outer face of the edge body portion of mattress casing 1S, adjacent said opening i9, the free ends of said prongs 2S will be disposed inwardly of the mattress casing. On placing washer 29 inwardly of the mattress casing, in a contactual relation with the inner face of the body portion of mattress casing 18, adjacent said opening 19, said prongs 28 are then bent in a direction away from the inner edge or the frame, until the free ends of said prongs 2S will come in contact with the adjacent edge of washer 29, as best seen in Figs. 6 and 7. By virtue of this action and arrangement said prongs 28 will clamp said washer 29 and the adjacent contacting portion of the fabric material 1S, to the free outer edge of said beadV 2S. In this manner the frame is effectively attached to the mattress casing 18, for providing a rigid lining for said Vopening 19.
A pair of said prongs 23, adjacent onelonger edge of Vthe frame, are bent intohinge loops 3i), for the purpose hereinafter specilied.
Co-acting with the said frame is flap 31, made. preferably of metal or plastic and provided with a plurality of perforations32, through which normally air may pass in or out of the mattress casing, but which are not largeV ceiving one end of coil spring 36, one set at each end of the mattress through the said frame llap 31 will be shifted inwardly upon its hinge against the tension of springs 36. The free edge of said ap 311 is inwardly bent for deiining lip 38 so that the same may ride upon the nozzle without scratching the same when the nozzle is inserted into or withdrawn from the mattress casing through the said opening.
The adjacent corners of said flap 31 are cut away, as at 39, for accommodating said springs 36.
A further modification of the present invention, illustrated in 1Figs. 9 to 15, inclusive, has a frame which includes bead 40, corresponding in its construction and action to bead l5 in the former modification of the invention. Said bead 4i) overlies the adjacent body portion of the mattress casing 13, and by its outer free edge contacts therewith. Said bead 4Q at its inner portion is provided with an integrally formed and inwardly extending tubular member 41. Struck out from the body portion of Asaid tubular member 4l, at its portion adjacent said bead 4), is a plurality of lugs 42, which are bent outwardly from the perimeter ot said tubular member 41, interposed between said bead 4% and said lugs 42 is theY adjacent marginal body portion of the mattress casing 18 and washer 43, wherein the same are maintained in a clamped relation. By means or" this arrangement the frame ismaintained in a rigid position with mattress casing 13.
Supported upon the inner end of said tubular member 4l is a metallic or plastic casing made of a pair of complementary sections 44, brought into a mutual contactual relation along line 45. To maintain the twosections 44 in their connected relation a metallic band 46 is provided in an encompassing relation with said sections 44. One end oi said band has slot 47. The other end is provided with tongue 48, which is passed through said slot 4,7, and thereupon bent upon the body portion of the end of said band from which said tongue 4S extends. By virtue of this arrangement band 46 remains ina firmly tied encompassing relation with said sections 44.
Each of said sections 44 adjacent its wall disposed nearest to bead 4i) is provided with recess 49, the two recesses 49 in the two sections 44 deline a mouth into which tubular member 41 is passed and in which the same rests. So as to make a close fit between said tubular member 41 and said casing 44-44, said tubular member 41 is provided with a circumferential groove 50 on its outer perimeter, into which groove adjacent marginal portion of sections 44 along recesses 49, are adapted to enter. Y
On its longer edge said tubular member 41 is provided with a Vcentral hinge loop 51. Perforated ilap 52 has a pair of loops 53 made upon one of its longer edges. Loops 51 and 53 receive rod 54. Thus said loops 51 and 53, in conjunction with said rod 5 4 constitute a hinge upon which ap` 52 is suspended and upon vwhich the same is adapted for swinging motion to or away from the adjacent free end of tubular member-41.
Each end of rod 54 has slot 55 for receivingV therewithin one end of coil spring Se. The other end of each coil spring 56 bears against the inner face of ap 52, as
, at 57. Coil springs 56 being under tensiomnorrnally plurality of struck out and outwardly projecting earsY 58,
each to be engaged by one end of coil spring 59. The opposite ends of several springs 59 are engaged with the adjacent edge wires 60 which are disposed and supported inwardly of the mattress.
Each of said sections 44, on itsV kface disposed opposite oi is provided with a complementary extension Y6l, the two extensions,- in the operative association of the two sections 44, define a sleeve, over which pipe 62; preferably made of rubber, is tted. Ringe 63 encompassing the end ofv-said'pipe 62"'which is over said sleeve,
maintains the adjacent end in a rigid engagement with said sleeve.
The opposite end of said pipe is provided with cap 64. Intermediately pipe 62 is provided with a plurality of openings 65 through which air may be sucked from or supplied to the mattress.
Said pipe 62 is supported within the mattress by a plurality of fasteners 66, provided with central loops 67 within which pipe 62 rests. Each end of each fastener 66 is provided with hook 68 for engaging coils 69 of the inner mattress springs.
From the hereinabove description it will be readily apparent that the frame and the tubular member 41 are supported within the opening of the fabric material 18 of the mattress. Springs 59 further support said tubular member 42 against lateral movement. Casing 44 is supported by means of tubular member 4i as weil as by pipe 62, the latter being supported by a plurality of fasteners 66.
It will be readily seen that pipe 62 may be as long as desired and may reach as far within the mattress as is desired.
It is also noted that flap 52 remains within the casing deiined by sections 44, and a nozzle of an air pipe connecting with a vacuum machine, when inserted through tubular member 4i, on pushing ilap S2 inwardly of the said casing, enters said casing dened by sections 44.
V-fhile there is described herein preferred embodiment of the present 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.
