M. MARSHALL VACUUM cLE'ANEz Oct. 4, 1932.
Filed Jan. 1.7, 1931 Patented Oct. 4, 1932 MAGARET MARSHALL, Ol' VANCC'U'VER, BRITISH COLUMBIA, CANADA VACUUM: CLEANER Application illed January V17, 1931. Serial No. 509,485.
This invention relates to improvements in vacuum cleaners and more particularly to the lusual fabric dust bag to be found on the majority of omestic vacuum cleaners.
An object of the improvements is to provide better and incre hygienic means for the removal of the dust contents from the cleaner.
Another object of my invention is to preserve the usual fabric dust bag in a more sanitary and cleanly condition than when used as a dust catcher and holder.
Another particular object of my invention is to provide means for disinfecting the room in which the vacuum cleaner is being used.
'l5 And a still further object of my invention is to provide a more expeditious and cleanly way for the ultimate disposal of the dust con- I tentsof the cleaner.
The invention consists in providlng an auxiliary container designed to fit snugly within the usual fabric dust bag found upon housei hold vocuum cleaners and to receive the dust therein, thereby protecting the outer fabric bag from contamination and dirt.
It is a well known fact that after frequent use the usual fabric dust bag becomes diiiicult to clean and to empty the contents therefrom as, owing to the escape of the air through the fabric, some portions of the fine dust contents are caused to adhere to the inner walls of the bag and these in' time add to the adhesive qualities and cause an accumulative effect of dust gathering therein, the consequences of which increase the unsanitary condition of the fabric dust container.
Another objectionable duty in connection with vacuum cleaners is the removal of the dustcontents from the bag, which, besides being diiiicult as before mentioned, is a messy job usually entailing the spreading out of newspapers for depositing thereon the dust collected in the bag and the wrapping up thereof and careful removal.
The above recited difficulties and objections are at once-removed by the use of my invention.
My invention will be more readily' understood by reference to the drawing accompanying and forming part of this application, in
fo which Figure 1 is a perspective view of the auxlliary contalner, showing a reinforced neck flange and a fabric valve inside of the container, the disinfectant pocket is shown dotted.
Figure 2 shows the protruding end'of the' auxiliary container beyond the reinforced ends of the fabric dust bag.
Figure 3 shows the protruding end of the auxiliary container folded over the end of the fabric dust bag.
Figure 4 shows the metal clip member applied over the ends of the auxiliary container and fabric dust bag to secure closure.
Figure 5 is a section taken on the line 5-5 of Figure 1 showing the disinfectant pocket.
Figure 6 is a-perspective view of the metal clip member used on some types of vacuum cleaners to close the end of the dust bag.
In the drawing like numerals indicate To like parts and 7 indicates a bag constructed of light, tough paper of a shape adapted to fit into the porous fabric dust bag 12 of 'the vacuum cleaner to which it is to be applied.
A reinforced neck flange 8 is formed on '.5 one end of the paper bag for securing under the clamp of the vacuum cleaner used for attaching the fabric dust bag.
It is desirable to have the paper bag a little longer than the fabric bag, when used with some types of vacuum cleaners, such as the new type Hoover, which makes use of an open ended dust bag closed with a metal clip as it then permits the protruding paper ends shown in Figure 2 being folded over the outside seams of the fabric bag, as shown in Figure 3, and being secured by the metal clip 11, as shown in Figure 4:.
In one side of the paper bag I provide an air release to permit the escape of the air therefrom while retaining the ne dust contents within the bag.
This air release shown at 9 in Figure 1 consists of a patch of finely meshed fabric pasted or otherwise secured into the side of the paper bag. It is at this point I provide my disinfecting means by having formed u on the inner surface of the fabric valve an on the inside of the paper bag a pocket to hold a. cake i of solid disinfectant. This pocket is shown ',100
at 10 in Figure 1 and a sectional view of this pocket is shown in Figure 5, and permits of the ready insertion of disinfectant when and as required.
It will be noted that the disinfectant p'ositioned in the pocket is in the path of the escaping air from the paper bag and is, there,-v fore, actively acted upon by the outgoing stream of air.
By this sim le means it is possible to disinfect and purify the air in the rooms in which the vacuum cleaner is being used and leave them smelling sweetly wholesome instead of having that musty smell so frequently found in recently vacuumed rooms. v
After use, it is a simple matter to remov the paper bag by removing the clamp at the lower end and tightly twisting the neck of thepaper bag to prevent the escape of the .dust contents, (care being taken not to destroy the paper flange collar) and then pulling out the paper bag frombthe open end of the fabric bag after the removal of the metal clip.
A particular advantage is the manner in which the paper bag discharges all the dust fan box and having its other end secured to the corresponding end of the fabric dust bag, said auxiliary bag having awindow opening in its side covered by a fine mesh screen and a pocket of fine mesh fabric secured inside MARGARET MARSHALL.

Having now fully described my invention, what I claim and desire to be protected in by Letters Patent, is:
l. In a vacuum cleaner having the usual fabric dust bag attached, the combination comprising an auxiliary containerfitting inside said fabric dust bag, said container having means by which it may be secured in said fabric dust bag, and having a screened window opening for permitting the air to escape therefrom, and means within the auxiliary container adjacent the window opening thereof for disinfecting the room in which the vacuum cleaner is used.
2. In a vacuum cleaner having the usual fabric dust bag attached, the combination comprising an auxiliary container iitting inside said fabric dust bag, said container hav? ing mea-ns for securing said fabric dust bag, means for permitting the air to escape therefrom, said means comprising an insert of finely meshed fabric on one sideof said auxiliary container and secured in and across a window opening in the wall thereof, means for disinfecting the room in which the said vacuum cleaner is used, said means comprising a pocket member formed on the inner side of said insert and of similar material to that of said insert, and shaped to receive a cake of disinfectant, said pocket being positioned in the streamline of said escaping air whereby the disinfectant is acted upon by said escaping air.
