2 Claims.

This invention relates to improvements in a suction cleaner, of the so-called vacuum cleaner type, and appertains particularly to the dust receiving bag.

An object of the invention is to provide an improved bag, to receive the out-put from a conventional motor-driven unit, that will thoroughly remove the solids and purify and disinfect the air passing therethrough.

A further object of the invention is to provide a bag of material impervious to air, having an inlet, for attachment to the motorized unit, and an outlet and between which inlet and outlet the air passes first through a dust extracting bag and then one or more filters for purifying and disinfecting the air.

A further object of the invention is to provide a bag-like attachment for use with a suction cleaner adapted to purify and disinfect the air out-put and having an outlet designed to removably receive a tubular conduit or other accessory.

A still further object of the invention is the provision of a bag for a suction cleaner, of the nature and for the purposes described, characterized by structural simplicity, durability, efficiency and low cost of production, being thereby rendered commercially desirable.

To the accomplishment of these and related objects as shall become apparent as the description proceeds, the invention resides in the construction, combination and arrangement of parts as shall be hereinafter more fully described, illustrated in the accompanying drawing and pointed out in the claims hereunto appended.

The invention will be best understood and can be more clearly described when reference is had to the drawing forming a part of this disclosure, wherein like characters indicate like parts throughout the several views.

In the drawing- Figure 1 is a sectional elevation of the improved bag attached to a conventional suction cleaner;

Figure 2 is an enlarged section of a means of attaching a conduitto the outlet of the bag;

Figure 3 is a detail elevation of the coupling there used;

Figure 4 is a side elevation, partly in section, of the connection of the bag with the motorized unit;

Figure 5 is a perspective elevation of a modified form of air cleaning attachment, being, of rubberized fabric with a separable fastener at its free end; and

fine particles of the dust continually blocking the pores of the bag reduce its efficiency, yet nevertheless gradually emanate therefrom'thus scattering dirt and germs about the house.

The present device, adapted to be used as an air-cleaning replacement for bags of the type in current use, provides first an effective dustremoving bag and then a. subsequent filtering and disinfecting of the air passed by the bag. This air-cleaner comprises a jacket or casing I having an outlet opening 2, adapted for removable attachment as desired to the out-put 3 of a conventional motorized suction cleaner unit 4, and an outlet opening 5, such for instance as that shown at the upper end and rounded to deliver downwardly. Within this jacket, which preferably is formed in two parts so that the upper end la; may be taken ofi, there is an airpassing dust-collecting bag 6, confined in the lower part in a reticulated wire cage 1 spaced from the inner wall of the casing, having its open mouth 8 concentric with and removably secured in the inlet 2, as by the wire clamping ring 9.

In the upper part of the casing l, i. e., between the dust collecting bag 6 and the outlet 5, the air purifying filters ID are interposed. Any desired number may be used and these may be impregnated with deodorant, disinfectant or other selected substance to treat or purify the passing flow of air. These filters I0 are shown as held between a fixed screen H and removable spacing screens I2, the last of which is confined by the interior flange I3 on the lower part of the casing I at the juncture therewith of the removable upper portion la.

As the stream of chemically treated air delivered at the outlet 5 is susceptible of various uses, as for instance disinfecting sick rooms, moth proofing cupboards, drawers, etc., the outlet 5 may be formed as a nozzle to receive a hose or conduit l4 that is removably attached thereto in any preferred or desired manner as by the spring urged stud IE on the conduit ferrule 16 and the cooperating indentation I! on the nozzle end 5.

A further adaptation of this invention is shown in Figures 5 and 6 where the air impervious casing I is of rubberized fabric with a reinforced inlet opening 2', adapted for attachment to a suction cleaner in the usual way, and an opening it, preferably at the opposite end. normally sealed with a separable fastener I8 and a non-closable air outlet 5 at or near this zipper-closed free end. In this modification, the removable, ioraminous. dust-extracting bag 6' has its mouth in the intake 2' while beyond the inner end of the bag a filter I0 is held, as by dome fasteners, not shown, between a pair of adjacent interior folds or tucks 20.

In this simplified embodiment, the outer Jacket or casing l' is much smaller than that shown in the rigid bag I in Figure 1. Access to the filter I0 is aflorded by way of the zipper-closed opening it, through which the dust bag 6' may also be removed if the inlet opening I be too small or otherwise inconvenient.

From the foregoing description taken in connection with the accompanying drawing, it will be manifest that a suction cleaner bag is provided that will fulfil all the necessary requirements of such a device but as many changes could be made in the above description and many apparently widely different embodiments of the invention may be constructed within the scope of the appended claims without departing from the spirit or scope thereof, it is intended that all matters contained in the said accompanying specification and drawing shall be interpreted as illustrative and not in a limitative or restrictive sense.

Having thus described my invention. what I claim as new and desire to secure by Letters Patent is:

1. A bag for a suction cleaner, comprising a jacket of material impervious to air having an inlet opening adapted for attachment to the out-put of said suction cleaner unit and an outlet nozzle at or near the remote end, a dustcollecting sack with its mouth arranged in said inlet opening. and at least one filter pad removablycarrled by said jacket, said Pad separating said outlet nozzle end from the rest of the jacket so that air passed by said dust-collecting sack must filter through said pad before finding egress from said outlet home.

2. A bag for a suction cleaner adapted for attachment to the out-put port of a suction cleaner and comprising a jacket of material impervious to air, an inlet therefor attachable to the output of said cleaner, a dust-collecting sack with an open mouth located in said inlet, an outlet nozzle near the free end of said bag and a replaceable filter dividing said jacket between said dustcollecting sack and said outlet nozzle.
