Application filed July 7, 1911. Serial No. 637,280.

is a specification.

This invention relates to an improvement 1n vacuum cleaners.

The primary ob ect of the lnvention is to provide a nozzle which will accommodate.

itselfto the surface to be cleaned, said nozzle having a flexible connection with the suction chamber, there being suitable means arranged within said suction chamber to rebeive the dust which is collected, said dust receiving means being conveniently removed from said chamber.

In the drawlngs :-,F1gure 1 1s a top plan view partly in section of the cleaner. Fig

2 is a side elevation partly in section. Fig. 3 is a front-elevation. Fig. 4 'is a detail view, showing the manner of supporting the nozzle.

In the drawings, designatesthe suction chamber, which is arranged to'house a piston 11. This piston is mounted on the forked extension 12 of a piston rod 14 which extends through the restricted neck 15 of the casing and which is reciprocated by means ,of the levers 16 which are pivotally supported by the bifurcated lugs 17 arranged on the casing, the levers 16 being connected to .the piston rod 14 by means of links 18-, the levers being moved toward and away from each other to reciprocate said rod. The plston 11 is provided with a central aperture 19 which receives the screw threaded end of a tube 20, a valve 21 which is secured to the piston between the forks of the extension 12 normally closing the end of said tube. Secured to the casing 10 is a substantially cylindrical casing 21' said casing being secured adjacent the .edge of the wall 22 of the casing 10. This wall 22 is provided with a central aperture 23 which receives thetube 20, a boss 24 being formed onthe plate or wall 22, said boss embracing thetube, guiding the same in its reciprocatory movement.

The casing 21' is bolted to the plate 22 of. the casing ilO'an'd is adapted to contam a.

dust receptacle 25 which is preferably in the nature of a porous bag. This porous bag 25 has its open end 26 supported between the inwardly bent ends 27 of the casing 20 and a cap 28 which embraces the. small end of the tapered casing 20, a wire or other suitable member being secured within the neck of the bag in order that the same may beheld against displacement. The'cap 28 is provided with the restricted extension 30 tube 31, the other end of said tube embracing an extension 32 of a nozzle 33. The nozzle 33 is supported by a plurality of'arms 34 which are secured to the cap 28. These arms 34 terminate in the angular extensions 35 which form bearings for rollers 36-, which rollers support the lower end of the device, facilitating its movement across the surface tobe cleaned. The inward extensions 35 extend beyond the rollers-36 and enter vertical slots 37 in the upturned ends or uprights vided with the longitudinal intake 38.

In operation the handles 16 are manipulated to create suction, within the chamber 10, the valves 41 and-42 being closed on the down stroke, airbeing expelled through the valve and through the 'valve 21in the upper compartment of the chamber, the air entering through the nozzle 33 either being conducted to the chamber by means of the tube-'20 or the valve 42, the tubebeing utilized for this purpose on the down stroke, and the valve on the up stroke. It will be noted by this construction that a constant suction is obtained with'the use of a single piston. 'Attention is also called to the manner in which the dust receiving bag is supported within the casing 21 and the factthat the same may be conveniently removed inserted in lieu thereof. Attention is also called to the nozzle 33 and the manner in which the same is supported, this nozzle being'supported in a manner which permits the same to moverelative to its support. WVhat is claimed is A vacuum cleaner comprising a pump, a

ing with said pump, a cap forming a removable closure for the lowenend of said 37 of the nozzle 33. This nozzle is pro filter casing, a pair of spaced arms exten'd-.

which extends within one end of a flexible when it becomes filled and an empty bag filter casing connected to and communicat ing from said cap, their' lov ver ends being In testimony that 1 ciuim the foregoing as inwardly extended, a roller journaled on my own, I have hereto aflixed my signature each of said ends, a nozzle, and a flexible in the presence of twb witnesses'.'
