` 4 claims. (ci. iss-.4)

The present invention relates to improvements .in bed deodorizers, yaudits principal object is to provide-arneans for deodorizing beds, Vespecially in fconnectionwith hospital beds, and it is .particularly effective Lin withdrawing -foul vair .from between ythe 4sheets of a bed, in deodorizing the :same and discharging the -puriiied air back zinto the bedroom.

A lfurther object of the invention .is to :provideha deodorizer of kthe 'character described which is simple :in construction, ,portable and may be readily carried .from bed to bed.

A further object of my invention is to 4.provide a deodorizing medium in the form of a cylindrical magazine interposed in the vline ofdraft Yand mounted in a housing :in :such va manner that .it .may `be readilylrem'oved for replacement purposes.

It is still :further proposed, .in the Ipresent invention, to provdea .novel suction head adapted for placing between .the sheets Nof `a bed, and -inwln'ch suc'ti-on'apertures are provided Vin such a manner that they may not easily be closedvbythe material ofthe sheets.

finally, it .is proposed-to prov-ide `a deodorizer `in which 'the ,purified Iair -is discharged against the -oor supporting lthe Vdeodorizi-ng uni-t 4for uniform distribution in all directions -over--theiioor area. u k

Further objects and advantages of my invention will appear as the sp'ecication proceeds, and the new and useful features of my deodorizer will be fully defined in the claims attached hereto.

The preferred form of my invention is illustrated in the accompanying drawing, forming part of this application, in which:

Figure 1 shows a side elevation of my deodorizer with a portion of the deodorizing unit shown in central vertical section and with a portion of a. connecting unit broken away;

Figure 2, a top plan view of the deodorizing unit, with a portion shown in horizontal section, taken substantially along line 2-2 of Figure l;

Figure 3, a section through a suction head taken along line 3 3 of Figure l;

Figure 4, a perspective view of one of `a series of bumpers used for supporting the deodorizing unit; and

Figure 5, a fragmentary detail view showing a side elevation taken at a right angle to Figure 1.

While I have shown only the preferred form of my invention, it should be understood that various changes or modifications may be made within the scope of the claims attached hereto, without departing from the spirit of the invention.

Referring to the drawing in detail, my deodorizer comprises in its principal features, a suction head 6, a deodorizing unit 7 and a conduit 8 connecting the two parts. The suction head is intended for placing between the sheets of a bed, and the unit is normally placed on the floor beside the bed, the conduit being sutliciently long, vsay 'approximately six feet, to allow for this arrangement.

The suction head 6 is in the form of an elongated, hollow, cylindrical body vformed `with lengthwise arranged rows of perforations 9. The head is'forrned with a `series of longitudinal channels 10 in the outer surface thereof, and the perforations are located in these channels to 'preventfthe sheet material from being drawn into the perforations when suction is appliedl to the head, whereby 'clogging of the yperforations is avoided.Y

The suction ,head terminates in a nipple'll which may carry a flap valve 12 4operable by ya handle 13 for regulating the draft (on the suction head.l One end of the conduit 8 Iis suitablygfastened upon lthe nipple, `as by a coupling '14.

The fdeodorizing unit 7 comprises a housing 15 hav,- ing a-cylindrical side 16, a ring-'shaped bottom 17 with .a large central opening 18 :and a removable cover 19 secured upon the side wall by any suitable means, as by l.the 'baycnetoint 20, shown in Figure 5. The bottom is supported by means of a series lof bumpers 21, one of which vis shown in detail in Figure 4, to maintain the bottom in spaced relation to the floor surface on which the housing rests.

There is provided, inside of vthe housing, a d'eodorizing or filtering unit 22, which `is cylindrical in form, of a diameter somewhat Aless'than the diameter of the housing wall, and located concentrically therewith, so as to leave an :annular -space or passage 23 "between the lilter and 'the yhousing wall.

The ilterin'g unit comprises ay pair of concentric screens 24 vsuitably spaced yby top and bottom rings 25, yand the space Ebetween fthe screens is filled with a suitable ltering medium, such as charcoal.

'The bottom endwof the iilter fis mounted in an annular channel formed -by va Apair of annular ii'anges 26 rising from lthe bottom" of the housing in concentric vrelation to the wall thereof. The filter unit v'is covered on top, bya disc 2'7. y

' The height ofthe filter ris somewhat less than that of the housing, as shown, and the removable coverk for the housing is concaved, as shown, to provide ample space above the filter unit, as shown at 28.

The cover 19 is provided with an intake nipple 29 to which the second end of the conduit 8 is attached, as at 30. The cover is also provided with a handle 3l extending across the major portion of the cover and of convenient size and shape for allowing the fingers of a hand to pass underneath the same.

Over the opening 18 :in the bottom of the housing there is mounted a motor 32 having a fan 33 facing downwardly. The opening may be covered by Wire netting 34 to prevent accidental contact with the revolving fan.

The motor may be supported over the opening in any suitable manner, as by brackets or by a cap structure 35 secured upon the inner rim of the bottom ring, as at 36, and upon the motor by a ring 37, the cap structure having ample openings 38 in the side and the top thereof to allow of free access of air to the bottom opening 1S.

In operation, the suction head 6 is placed inside the bed, preferably between the sheets, while the deodorir-y The peculiar shape of the suction head prevents the perforations from being closed by the bed sheets so that air from within the bed may readily enter.

The large area of the cylindrical filter provides ample filtering medium, and due to ythe construction shown, the entire filter area is used with substantial uniformity.

When the filter has become ineffective, a new one may be readily substituted upon removal of the cover 19.
