lmown as vacuum cleaners.

The principal object of this invention is to provide a manually operated portable cleaner for the purpose described, which is composed of a minimum number of parts, and is therefore simple in construction.

Another object of the invention is to provide a cleaner of the class described in which a novel construction of bag-holding means is employed.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claim hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claim, may be resorted to without departing from the spirit or sacrificing any of the advantagesof the invention.

In the drawings: Figure 1 is side elevation of the device, Fig. 2 is a longitudinal sectional view therethrough, parts of the same being shown in elevation, Fig. 3 is a transverse sectional View taken on the line 33 of Fig. 2, and Fig. 4: is a detail end elevation with the operating levers removed, Fig. 5 is an enlarged sectional view of the clamping ring.

Like reference numerals designate corresponding parts in all the figures of the drawings.

Referring to the drawings, 5 designates an open ended cylindrical shell of any suitable material, and provided with a plurality of supporting feet 66 which are securedto a suitable base 6% Centrally formed in the top of theshell is an outwardly flared opening 7, and projecting from'said shell around the opening is a raised annular seat 8. A tapering annulus 9 is-disposedxwithin Patented Get, 2345, HMS.

said opening 7 and is of a shape corresponding thereto, the smaller end of said annulus being at the bottom. A laterally projecting flange 10 extends from the upper edge of said annulus and a washer 11 is disposed between the seat 8 and the said flange... A clamping ring 12 is proyided with an inclined outer edge 13, the exterior diameter of the ring being greater than the interior diameter of the smallest or lower end of the annulus 9. has its mouth disposed within the annulus, and secured thereto by the clamping ring 12 as will be readily understood. A concavcd closure plate 15 is disposed above the opening, and is provided with a laterally projecting marginal. flange 16 which is adapted to rest upon the flange 1.0 of the annulus.

intermediate the said flanges. Alined openings are respectively formed in the seat 8 and flanges 10 and 16. There may be as many of these openings as desired, and associated with these openings are bolts 21, by means of which the closure plate 15 and the annulus 9 is secured to the cylinder A nipple '22 extends outwardly from the clo sure plate 15 and communicates with the lIl-' terior thereof. Secured to this nipple one end of a flexible pipe 23, the other endof the pipe being provided with a nozzle 24: having an elongated and narrow inlet opening 25.

Disposed within the cylinder 5, and on either side of the opening T. are partitions 26-26, by means of which a central air chamber 27 is formed. The fastenings of these partitions are located withiii the air chamber. as shown at a. Bellows 2828 are respectively secured to the partitions, and extend outwardly toward the ends of the cylinder Each of these bellows is provided with a head 29 having an car 30 cenheads 29 of the bell A coupling rod 38,

normally disposed above the cylinder, has its ends pivotally connected to the levers 36 as at 39-39. By reason of the fact that the partitions 26 have their fastenings located in the air chamber 27, these fastenings are accessible through the opening 7, for removal of the partitions in the event that repairs to the bellows are necessary.

From the foregoing, it will be observed that as either of the hand-levers 36'is oscillated, the bellows 28 will be alternately operated, one of the bellows drawing in air and the other exhausting the air brought in It ill be observed that as one of the bellows is expanded, air will be drawn in through the opening 25 of the nozzle 94, through the pipe 23, the

closure plate 15,1;hrough the bag 14, through the openings 31, and into the bellows. Upon n'iovement in the opposite direction of the lever, this air will be forced out through the openings 32, past the outwardly opening flap-valves 34., and into the atmosphere. It Will also be observed that as the air passes through the bag 1%, all foreign particles will be left Within the bag. By this construction a continuous suction is created. When the bag 14 has received a certain'amount of dirt, the bolts 21 can be loosened and the bag rcmoved.

In a vacuum cleaner, the combination with a tubular cylindrical member having a cylindrical opening in the wall thereof, of spaced partitions \vithin the casing on opposite sides of said openings respectively, said partitions having formed therein, outwardly opening valves controlling the openings in
