'vacuum cleaners whereby' it is possible to use a cap or bag of increased area without having it -hang looselyfromits holdingmember likea sack., but instead thereof, to provide a mouth-piece or the like for thesuction pipe, of increased diameter with adust cap or-'guard stretched across the mouth. thereof,

.The invention Willbe readily understood from the following desoription, -reference being had to the accompanying drawings, in Whic ,-fh

Figure `1I is a perspective view of a por- .tion of one `off-the 'styles of vacum cleaners having a dust bag or sack attached to .the suction pipe thereof; Fig.J 2 is a detailed view, showing one embodimentcof my invention and the'reconstruction necessary to its embodiment in avacuum cleaner; and Fig. 3 is a similar view .of another embodiment of. theinvention.4 p

Referring nonv to thel drawings, l designates a' dust and dirt receptacle or chamber, which may be of any4 desired'shape, provided `with a gathering nozzle 2, connected ,thereto in the usual manner'by means ,ofa tube or pipe 3, which is preferably extended into fthe dust receptacle 1, as indicated.

L -designates;the suction pipe of' one of .the cleaners now on the market, being provided with -a dust b agor sack, as 5, hangingfrom said suction pipe in the manner shown. My first attempt to overcome the objection hereinabove mentioned, namely, to keep the dust from adhering to said bag Or sack and from filling the meshesthereof so as to prevent'the freecirculation or passage of air therethrough, was to place a Weight Or ball 6 loosely within said bag Or sack, whereby the operation of the machine would keep said Weight or ball moving Within the cap and thereby knock the dust therefrom.

This is partially successful. The present' bag or sack, however, in order to get more area for the air to pass through, -is made large and hangs from the suction pi )e like a sack, as shown. The .ball draws t e bag do\\'n\.vardly under its Weight and as, the apparatus is moved, the ball swings therein hannnock fashion, and unless the movement is unusual, as by jerks or vigorous shaking,

the ball moving with the bag does -not succeed in keeping`y the dust from working into the meshes thereof, although it enables the machine to work longer before becoming clogged, than when no ball or weight is used therein. Under this showing of the present styleof cleaners, said bag or cap hangs down int-o thc dust receptacle l and must be carefully put into the receptaclewhen lthe parts 1re being put together, in order to prevent its becoming .folded or crimped around the ring or mouth piece of the suction pipe and punctured or Worn. This increases the difliculty in taking the parts away from 'each other for Ithe purpose of emptying the dust.

receptacle and cleaning the bag.

Referring now to Figs. 2 and 3, I provide a mouth-piece' of relatively -increased .diameter, whereby to enable me to vget -increased area ofdust cap or guard without permitting it to hang loosely from the mouthpiece. I prefer'to have this cap or guard stretched just loosely enough so that it can vibrate slightly in its middle portion. In Fig. 2 I have shown a weight mounted upon a pivoted arm 8, so pivoted that the slightest movement of the apparat-us will cause said weight or ball to swing against the cap or guard 5, thereby operating at each movementof the machneto strike the Vcap and knock the dust therefrom. In F ig.

' the cap is taken up, the stopping of this movement suddenly, operates to throw or jerk the dust and dirt from the cap. Thus it will be seen, by thus agitatingthe cap or` guard by these moving members or weights the dust is continuously kept knocked from the cap with each movement of the cleaner upon the surface being cleaned. I also providean 'attaching band for securing said cap or guard to the ring -ings made for purposes of portion of the mouth-piece, which'said band 1s slightly inturned at its outer edge, as indicated at 9, whereby to overlap said cap or I have shown anddescribed m invention as applied to hand cleaners, but o not limit it to any particular kind of vacuum cleaner, Y

but intel-1d tocover it in its'application to any vacuum cleaner where a fabric or other dust cap or guard must be kept free from the dust and. dirt in order to secure the bt results. I am also aware that modifications and changes can be made in the construc-A tion and application of the invention to the purposes -int-ended, and I do not, therefore, limit the invention to the particular showillustration.

Iclaim: f

l. In a vacuum cleaner. adapted .to be moved bodily over the surface to' be cleaned, the combination with the dust receptacle and dust cap thereof of a movable weight in combination with said dust cap and adapted toagitate it with each bodily movement of said cleaner, for the purpose indicated.

2. A suction cleaner comprising a hollow body portion having a part to enable said body portion to be manually manipulated to move the cleaner over the surface to be cleaned and provided with an inlet. at; one

end and an outletat the other end, a'dust, separating device mounted within y,said body portionbetween said inlet and said outlet, and means actuated by the manipulation of said body portion in the normal operation of the cleaner to prevent the accumulation of dust onsaid device.
