A further object is to produce a hag. which to will not contract when not in use.

A further ohiect is to produce a device which may he attached to any of the stand ard forms of vacuum cleaners now upon the market,

in vacuumsweepers, the dirt taken 11 by the sweeper is usually blown into a bag, rom B which point the air escapes through the prosity of the goods iormin the bag.

After thebag becomes filled withdirt or dust, it is customary to open the bag and vdeposit the substance in a paper or other, receptacle. This procedure is often extremely dirty, resulting in'dust permeating the air, and in reality, the bag cannot be sufficiently cleaned. f In the present attachment .l have endeavored'to overcome this annoyonce andlnconvemence and have produced means whereby the bag can be entirely, evacuated ofrtheactual dirt or dust therein.

In the accompanying drawing wherein for thepurpose oi illustratidn is shown a preferred embodiment of my invention, the numeral 5 designates the customary vacuum cleaner motor housing having actmventional handlefi, to which handle the bag is suspendedbya chain 7 The bag in my inven- 0 tion is substantially of the same'shape as has sections.

drawing forming been previously used. The difi'erence, how ever, over the ordinary ones, is that l slit the bag from a point near the top as at Qto a point near the bottom 11, and along the edge M of the slit I prefer to stitch or otherwise se cure a fastener of the type commonly known as a zipper, A flap 12 is stitched within the bag so as to over-lie the zipper joint as best illustrated in Figure 2, and prevent the dust in the bag from clogging the zipper Around the circumference of the bag 1 form pockets 18 by attaching strips 14. around the bag at suitable spaced points,

, and in the pockets thus formed,'betweenthe strips and the bag, I place spring steel pieces A6. The result of this construction is, that whenthe Zipper is closed, the bag as a whole is not unlike the ordinary vacuum sweeper bag,,except;that the steel-pieces 16 maintain the bag in expanded condition in counter dis-' tinction with the usual bag which collapses as soon as the air, pressure drops, due to the shutting offof asweeper. I

When it is desired to empty the bag, a newspaper or receptable is laid upon the floor and 575' the sweeper is brought to such a position that the bag overlies the dust receiving receptacle. By now runningfthe zipper from one end to the other so as to open the slit, the result will he that the dirt within the bag will an upon the paper, for the reason that the spring 1 members will move to the dotted line position of Figure 2 and completely open the bag to expose its interior therein; Thus the bag may be quickly emptied withl out stirring the dirt up as is necessary in the shaking of an ordinary vacuum sweeper bag. It is to be understood that the form of my invention herewith shown and described is to e be taken as a referred example of the same and that varlous" changes relative to the material, size, shape-and arrangement of partsmay be resorted to without departing fro'mthe, spirit of-the invention or the scope of the subjoined claim. v I

Having thus described my invention, l P claim 1 A bag for a vacuum cleaner having a slit extending from the lower end thereof to a point ad acent the other end, means for opening said slit and blosing saiid slit, :1. flap st1tched within the bag and overlying the slit, and a pluralit of spaced sprin members carried by sald bag for retaining the cross sectional area of said bag at its greatest dimension at all times.

In testimony whereof I aifix my signature.
