3 Claims. 1

The present invention relates to suction cleaners in general and more particularly to a new and novel combination vaporizer and blower the ambulant type.

The present invention also relates to mothproofing fabric materials, such as clothes. By moth-proofing is meant treatment, for example with the gas of para-dichlorobenzol or paradibromobenzol, to protect against moths. The invention also relates to disinfecting or air conditioning or other treatments of articles wherein a gas such as air laden with the vapor or an insecticide or perfume is used. Furthermore, the invention relates to coupling means for connecting a hose to a vaporizing attachment for a suction cleaner.

It is therefore an object of the present invention to provide an attachment for a suction cleaner whereby the exhaust therefrom may be utilized for vaporizing pulverized crystals and conveying the fumes to rugs, upholstered furniture, drapes, clothing, closets, baseboard and floor cracks.

It is another object of the invention to provide an attachment for a suction cleaner to utilize the fumes therefrom as vaporized in the attachment for purifying the air and for disinfecting sick rooms.

Furthermore, it is an object of the present invention to provide a simple vaporizer attachment which may be readily attached to or detached from the suction cleaner exhaust outlet, for carrying out any and allof the above objects or which while still in its attached position may be rendered inoperative as an insecticide or disinfectant vaporizer in order to permit the normal operation of the suction cleaner as a blower for cleaning by blowing.

These and other objects may be attained by ized when supported on the attachment and with the glass container removed the attachment is adaptedfor cleaning by blowing.

These and other more specific objects will appear upon reading the following specification and claims and upon considering in connection thereattachment for suction cleaners, preferably of with the attached drawings to which they relate.

Figure 1 is an assembly viewshowing the invention as applied to the exhaust outlet of an ambulant type floor cleaner and adapted for vaporizing a material for moth-proofing;

Figure 2 is an enlarged view of the vaporizer attachment mounted on the exhaust outlet of a suction cleaner, adapted for cleaning by blowing;

Figure 3 is an exploded isometric view illustrating the combination vaporizer and blower attachment with the container for the vaporizable material detached;

Figure 4 is a rear view in elevation of the attachment illustrating the various means for securing the vaporizer attachment and blowerto the exhaust outlet of various types of commercial cleaners; and,

Figure 5 is a vertical sectional view taken along the line 55of Figure l, illustrating the flowof air through the vaporizer attachment as it is adapted for vaporizing a material for dlemothing, disinfecting or perfuming.

Referring to Figure 1, a conventional suction cleaner I0 is shown which includes the usual motor driven fan, suction nozzle and agitator therefor, wheel supported and adapted to-be propelled-bythe conventional handle to which a dirt bag is usually attached but for the purpose of utilizing the combination vaporizer and blower attachment 1 l of this invention the bag has been detached for aifixing the attachment to the exhaust outlet of the suction cleaner. In order to describe the operation of this invention, the attachment I I hasbeen illustrated in'conjuhction with a conventional garment bag I2. The earment bag is connected with the vaporizer attachment H by a conventional wand construction [3, hose I4 and a cleaning tool hose connection 15;

The combination vaporizer and blower attachment I is provided with a mounting bracket lfihaving latching means 11 and 18 adapted to be attached to the suction cleaner by latching means 19 and 20 shown in Figure 1. In the suctioncleaner illustrated in Figure 2, the combination vaporizer and blower attachment H is afiixed to the exhaust outlet of the suction cleaner ID by laterally positioned ears 2| adapted to be secured to the suction cleanerby clamping means 22' shown in Figure 2. It is thus obvious that with this construction, the combination vaporizer and blower attachment is adapted for mounting on existing conventional cleaners.

The mounting bracket l6 showninFigure 5 is "secured by suitable means 22 to a molded plastic housing 23 forming the combinationvw porizer and blower construction. A screen 24 is positioned between the opening of the bracket 16 and the opening 25 of the attachment in order to prevent crystals of vaporizable material positioned within a glass jar 26 from discharging into the exhaust of the suction cleaner in the mounted position thereon as illustrated in Figure 1. The jar 26 is detachably mounted in an enlarged opening or jar socket 21 by threads 28 which receive threads 29 formed on the jar. It is within the scope of the invention that standard glass jars may be adapted for use with the combination vaporizer and blower attachment as are commercially available although it is obvious that other forms of jars and securing means thereon may be utilized.

Axially located in the housing 23 with respect to the axis of the jar 26 is a tube 36 which serves to discharge the exhaust air from the suction cleaner into the jar, as illustrated by the arrows in Figure with the jar in position, and the tube 30 also serves as a wand connection when the apparatus is used solely for cleaning by blowing, as illustrated in Figure 2. Referring to Figure 2 when the cleaner is utilized for blowing, the wand I3 is connected to the tube 36 by an umbrella type latch mechanism 3| provided with a locking detent 32 adaptedto engage a groove 33 machined or molded within the tube 36. This particular form of connection permits the ready attaching and detaching of the wand to the combination vaporizer and blower attachment upon the actuation of a thumb control button 34 also permits swiveling of the wand within the tube 36. The latch mechanism which is of standard construction is mounted within a dog-house 35 to prevent excess leakage within the wand to reduce the efficiency of operation.

When utilizing the apparatus for vaporizing a substance for moth-proofing and the like as shown in Figure 5, the flow of air follows that of the arrows through a tube 36 to which the ,wand 13 is adapted to be connected in the manner as described with reference to Figure 2. The tube 36 is molded integrally with the housing 23 and is connected by a passageway 38 extending laterally and downwardly as illustrated in Figure 4 to an annular chamber 31 formed by the tube 3|] and the housing 23. The rear end of the passageway 38 is provided with a detachable cover plate 39 preferably formed of sheet metal anad complementally formed with respect to the passageway 38 to form a closure for the rear end of the tube connection 36, as illustrated in Figure 5, and to permit the mounting of a screen 40 across the passageway 38. The cover plate 39 is afiixed to the housing 23 by securing means 4|. The screen 40 prevents the crystals within the jar 26 from discharging through the tube 36 into the dusting tool hose [4 thus permitting eflicient use of the vaporizable material.

It is thus obvious that there has been disclosed asimple combination vaporizer and blower apparatus which is adapted for cleaning by blowing'as illustrated in Figure 2 by mounting the dusting tool hosewithin the tube 36 and may be readily converted to a vaporizing apparatus by affixing the jar 26 containing the vaporizable material to the apparatus as illustrated in Figure 1 and attaching the wand as illustrated in Figures 1 and 5 to the tube 36 to discharge the air conditioned by vaporizable material either for moth-proofing, deodorizing, disinfecting, and

thelike. 7,.

With the various parts assembled as shown in in the jar 26, the suction cleaner may be operated .for moth-proofing the garments within the bag l2 upon discharge of the air conditioned vapor through the hose l4. Referring to Figure 5, the flow of air from the suction cleaner is upwardly through the tube 36 and through the vaporizable material within the jar 26 and downwardly through the annular passageway 31 to be discharged through the passageway 38 and finally through the tube 36 to which the wand l3 and the hose [4 are connected to discharge the fumes of the vaporizable material for disinfecting, fumigating, air purifying and the like.

If it is desired to actuate the combination vaporizer and blower attachment as a blower, the operator simply detaches the wand I3 from the apparatus, as illustrated in Figures 1 and 5, by depressing the button 34. The operator then reinserts the wand within the tube 36 as illustrated in Figure 2 after detaching the jar 26 from the position as shown in Figure 1. Referring .to Figure 2, the exhaust air from the suction cleaner then discharges directly through the tube 30 through the wand l3 and hose I4 and through the various tools which may be connected to the cleaner tool hose connection l5 for cleaning by blowing. It is also obvious that with this attachment the suction cleaner may be pulled along through the connection of the hose with the handle of the suction cleaner in its vertical storage position as shown in Figure 1.

After the operator has utilized the combina I tion vaporizer and blower attachment either for cleaning by blowing or for moth-proofing, disinfecting and the like operation, the suction cleaner may be restored to its original condition by releasing the clamping means 2|] of Figure 1 or 22 shown in Figure 2 permitting detachment of the apparatus, whereupon the dirt filtering bag may be replaced in the reverse order. The cleaner is then ready for its normal operation as a typical ambulant type floor cleaner.

It is to be understood that whereas there has been described and illustrated a practical and operable combination vaporizing and blower attachment for a suction cleaner as applied to the exhaust outlet of an ambulant type suction' cleaner, nevertheless many changes may be made in the size, shape, number and disposition of parts without departing from the spirit of this invention.
