Application filed October 4, 1923. 8 er1al No. 886,495.

To all whom it may concern:

Be it known that we, Louisa H. PATTER-Q soN and HANNAH L. H. PATTERSON, citizens of the United States, residing at Coronado,

Diego, State of California, have invented certain new and useful Improvements in Sanitary Dust'Bags, of which the following is a description, reference being had to the accompanying drawing, and to the figures of reference marked thereon.

This invention relates to vacuum cleaners.

The object of the dust bags for present invention resides in providing a combined non-porous'paper and cloth bag which is sanitary, cheap, easily constructed, and is of suificient durability to give service and good suction.

Another object of this invention is to provide a non-porous paper bag which is made economically so that it can be destroyed after use or can be easily cleaned after each use and used repeatedly if desired.

Stillanother object of this invention resides in providing a dust bag composed of substantially non-porous paper material which will retain the dust and dirt without permitting it to pass therethrough.

Still another object of the invention resides in providing a dust bag composed mainly of paper material which will prevent the dust and dirt passing through the body of the bag, such for instance, as the manner in which the dust sifts through the meshes of the present-day cloth bags, and yet, at the same time, will permit air to pass out of the bag to provide the requisite suction for the cleaner.

Another feature of the invention resides n'f roviding a bag composed substantially of -on-porous paper provided with a suction maintaining portion of porous material and a paper nozzle formed for attachment to the cleaner nozzle so that the emptying of the bag is facilitated.

"Further objects of the invention reside in the details of construction of the combined paper and cloth bag, the manner of uniting these component parts, and the means for attaching the bag to the cleaner nozzle and supporting the bag in position on the cleaner.

These and other objects will be apparent from a perusal of the following specification when taken in connection with the accompanymg drawings, wherein- Figure 1 is a side elevation of one form of our ag as applied to a vacuum cleaner;

ig. 2 is a; modification thereof;

' Fig. 3 is another form;

Fig. 4 is still another embodiment;

Fig. 5 is a sectional View of Fig. 1;

Fig. 6 is a sectional view of Fig. 3, and

Fig. 7 is an enlarged view of the device shown in Fig. 4.

Referring now to the drawings in detail, instead of making the bag of cloth, as heretofore, the bag is composed mainly of a durable, non-porous, paper. This paper is formed as a tube or receptacle portion 1 having in the form illustrated in Fig. 1, a paper mouth portion 2 of a size to snugly fit the usual metallic nozzle 3 of the vacuum cleaner 4. The paper mouth 2 is held on the nozzle by the usual clamping ring 5. The other end of the tubular portionyl is provided with a porous section 6 in the form of a tube attached thereto as at 7 as by gluing, stitching or otherwise. This section 6 1s preferably cloth of sufficient extent and size of mesh to ive suiiicient volume to maintain the desire suction for the cleaner. The mesh of the cloth is arranged to dust and dirt passing through with the air. The extreme outer end of the cloth section 6 may be open and is adapted to be closed by the usual clamp 8 which as well known, has a connection to the sweeper or cleaner pole 9. The bag is thus held in position. By forming the bag mainly of non-porous paper, the

construction, when the bag has been used once or twice, it can be burned up with the trash, due to relatively low cost of produc tion. Furthermore, it is possible to obtain better suction with this style of bag than with heavy cloth or double cloth bag of present-day construction. Air does not get prevent the.

In Fi 2, the invention is illustrated with a centra paper portion 10 and a cloth mouth 11, in lieu of the pa er mouth 20f the Fig.

1. In Figures 3 an 6, the paper portion 12 is provided with a'cloth mouth 13 and an upper cloth portion 14 which is permanently closed as by sewing or gluing at 15 and is formed with a tab 16 for connection to t e pole 9. In Figures 4 and 7, the ha is n ordinary type of commercial'paper ag, of non-porous paper 17, having a lower cloth portion 18 for connection to the nozzle 3. of the cleaner. To the upper portion of the bag is glued or sewed the string or cord 19 for fastening the bag 17 to the pole 9. This can be accomplished by means of stickers 20.

It is obvious that minor changes in the details of construction and the arrangement of the parts may be made without departing from the spirit of the invention as set forth in the appended claims.

Having thus described the invention, what we claim as new and desireto secure by Letters Patent, is-

1. A dust bag fora vacuum cleaner composed mainly of non-porous paper and provided with a cloth portion for the egress of the air.

2. A dust bag for a vacuum cleaner formed in art of'substantially non-porous paper fabric, said bag having at least one end section of porous material to provide an outlet for the air.

3. A dust bag for a vacuum cleaner comprising a non-porous paper tube having end tubular sections of cloth for attachment to the nozzle and metal holder respectively of the vacuum cleaner.

In testimony whereof, ,we afiix our signatures.
