UNITED STATES CLARAl M. JAQUITH, OF DENVER, COLORADO.
DUST BAG FORVACUUM CLEANERS.
Application med May 28,192.4. serial No. 716,291.
To all whom it may concer/n:
Be it known that I, CLARA M. JAQUITH,
a citizen of the United States, residing at Denver, the city and county of Denver and -State of Colorado, have. invented certain new and useful Improvements in Dust Bags for Vacuum Cleaners; and I do declare the following to bev a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a. part of this specification. V
This invention relates to improvements in dust bags for vacuum cleaners.
It is well known to all who employ ordi.- nary vacuum cleaners that these are far from being as cleanly! and as sanitary as they should be. The main reason for this is that the dust is discharged from the blower into a bag, the w`alls of which mustbe sufficiently porous to permit the air to escape. The walls of the dust bag act as a strainer whose function it is t'o-retain the dust while the air escapes through the walls and into theroom. It, is, of course, impossible, with the ordinary cloth` bag, to remove all of the dust from `the`air, as much of the dust and dirt is in the form of an impalpable powder so fine that it passes freely through the meshesbet-ween the threads. This fine dust o-ften carries the disease germs which by this means become widely scattered. The proof that dust passes through the walls of the bag can readily be produced, as it is only necessary to carefully dust articles of furniture before the cleaner is used and then to note ho-w much dust settles upon this furniture after the cleaning is over.
It is evident that the ideal bag would be one that would remove all ofthe dust from the air so that. the latter, as it', reentered the room, would be entirely clean. It has, however, been impossible to produce mate' rial that will screen the dust out of the air completely.
It is the. object of this invention to pro duce a dust bag that shall be so constructed that the air which leaves the same shall be filtered to such an extent that it is for all practical considerations, clean.
My invention, briefiy described, consists in making the bag of very closely woven fabric which is practically air-tight or the the air to pass through it.
fabric may be rubberized or filled with some material that renders it air-tight. For the purpose of permitting the air to leave the bag as fast as it enters, I provide a vent which is provided with an air filtering means. This vent/is preferably formed inA the manner which will be hereinafter more fully described and comprises a box which is adapted to contain filtering material, such as a wet sponge, wet felt or cotton waste or any other suitable filtering `mate-rial. The box is pro-vided with means which will cause the air to travel through the filtering material.
In order more clearly to describe my invention, I shall have reference to the accompanying drawing in which one embodiment thereof is shown, and in which:
Fig. 1 is a. side 'elevation of a vacuum cleaner showing the bag constructed in accordance with my invention;
Fig. 2 is a section of the air filtering device; and
Fig. 3 is a view similar to that of Fig. 2, but showing the filtering material in place. Numeral 1 represents a dust bag which may be similar in shape and size to those now in common use. This'gbag diers from 'those 4ordinarily employed in this, that it is air-tight or substantially so. The vent- 2, through which the air leaves the bag, comprises a metal box having a wall 3 pirovided with outwardly extending annular flanges 4 and 5 between which the material 6 of the bag is clamped as by means of rivets 7. The bottom 8 of the box is bent inwardly and has a central opening 9 which is closed 'by a woven wire screen 10 or which may be closed by any other suitable foraminated material.
A cover comprising a ring 11, to which is secured a woven wire top l2, serves to close the box. The box just described is designed to contain the filtering material 13 which may be a wet sponge, wet felt or wet cotton waste. In fact, the filtering material may be any suitable material that will'permit of the box is curved upwardly towards the cover, the air will enter the filtering material close to the center of the same and will be obliged to pass through it instead of Since the bottom It is evident that many specifically different designs or filters may be invented, any one of which will serve the same purpose as the one described, and I wish it tobe understood that the one described above is'illustrative merely and is to be regarded as an element of the combination.
From the above, it is apparent that I have produced an improved dust bag for vacuum cleaners that will'ilter the air as it leaves the bag so as to remove from it all dust and dirt, thereby converting the vacuum cleaner into really cleanly and sanitary devices.
Having now described my invention, what I claim as new is:
l. A dust bag for vacuum cleaners comprising, in combination, a flexible, substantially air tight fabric bag adapted to be secured to the exhaust opening of a vacuum cleaner and to receive the dust and dirt from the latter, said bag having an opening, a metal container projecting from opposite sides of the wall of said fabric bag.
and located lwithin the opening and secured to the edges thereof by means forming an air tight seal, said container being adapted to vreceive a filter medium, the top and bottom of said container being foraminated whereby air may pass outwardly through the container.
2. A filter device adapted to be attached to the dust bag of a vacuum cleaner, comprising a box having an integral bottom portion provided with an opening, said bottom projecting inwardly into the box, the opening in sald bottom being closed by a screen, said box having a removable comprising a ringlike member adapted to telescope with the sides of the box and a piece of screen connected to the ringlike member, said box being adapted to receive a wet sponge through which air must pass when leaving the bag and to which the dust contained in the air will adhere.
3. A filtering device adapted to `be attached to a dust bag comprising, in combination, a cylindrical box having a bottom member that projects into the box, said bottom member having an, opening closed by reticulated material, a cover member adapted to be attached to the open end of the box, said cover member consisting of a ring to yone edge of which a screen member is attached, said box being adapted to receive a filter medium consisting of a sponge bers of L-shaped cross section secured to the outside of the box and adapted to clamp between them the material to which the device is attached. 4. A dust bag for vacuum cleaners formed of substantially air-tight fabric having an opening for the escape of air, a metal container located in the opening and secured to the material of the bag by means forming an air tight seal, said container having an inwardly convex bottom member provided with openings, and an outwardly convex cover member also provided With openings.
In testimony whereof I aflix my signature.
