UNITED sTATEs PATENT WALTER THOMAS WHITE, OF ST. JOHN, NEW BRUNSWICK, CANADA.
VACUUM-CLEANER.
Specification of Letters Patent.
Patented June 1d, 1913,
' To all whom t may concern:
Be it known that I, WALTER THouAs TWHITE, a subject of the King of Great Britain, residing in the city of St. John, Province of New Brunswick, Dominion of Canada, have invented certain new and useful Improvements in Vacuum-Cleaners, and do hereby declare that the following is 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 saine.
My invention relates to improvements in vacuum cleaners and t-he object of the invention is to devisea vacuum cleaner which will have better suction than those at present in use, and a. further object is to construct a vacuum cleaner in which the motor will be more effectively cooled than in those at present on the market.
The invention consists of a base, a casing above the base and removably secured thereto, an electric motor having a vertical shaft extending abo-ve and below the same, said motor being suitably mounted on top of the base, and the lower end of the motor shaft extending down through an enlarged central aperture in t-he base, the top of said base having a circular wall adjacent to the outside periphery thereof, fans on both the upper and lower ends of the shaft, casings extending ver said fans and having centralv inlet apertures therein, the top fan having a circumferential outlet aperture in the bottom thereof and the bottom fan having an inlet aperture extending circumferentially around the side thereof, the inlet aperture in the lower fan casingregistering with the aperture in the top of the base, a plate removably secured to the base inclosingthelower fan, said base having an exhaust aperture in the side thereof, a partition extending across the casing intermediately of the height of the same, said partition having a central aperture registering with the inlet aperture in the upper fan casing, a wire mesh screen extending' across the aperture in the partition, a dust bag above the screen removably held within the casing, a cover for the casing having a sight glass in thetop thereof and a partition formed below the sight glass having a central aperture therein, the side of the cover having a suitable aperture therein into` which the lend of the hose fits, said cover being removably secured to the casing all as hereinafter more particularly described andillustrated in the accompanying drawing in which:
Figure 1 represents a vertical section for vacuum cleaner constructed according to my invention. Fig. 2 is a cross section through the line .fr-x (Fig. 1) showing the upper fan and casing therefor. Fig. 3 is a cross section through the line g/-y (Fig. 1) showing the top of the base.
Like characters of reference indicate corresponding parts in the different views.
1 is the base having a top 2 with a central aperture 3 therein and a circular wall f1 thereon near the inside periphery of the base.
5 are deflecting blades, suitably curved and extending from the wall to the edge of the aperture 3.
6 is a asket surrounding the wall 4 and inset in t e base.
7 vis an exhaust aperture in the side of the base below the top 2.
8` is an electric motor having a vertical shaft 9 extending above and below the motor; the lower end of the shaft 9 extends down through the aperture 3 in the base. The motor is suitably mounted on the top 2 of the base by being secured to the. lugs 10 by the screw bolts 11. 12 and 13 are upper and lower, fans having suitably curved blades 14 and 15 mounted on' the upper and lower ends of the shaft 9 respectively. 16 is the casing of the upper fan, said casing being turned downwardly at its outer edge and being of"larger diameter than the bottom surface 12 of t-he fan thus leaving a circumferential aperture 17 between the two through which the air discharges.
1.8 is the casing of the lower fan, said casing being of the same diameter as the bottom surface 13 of said fan and having no downwardly turned outer 'edge thus leaving 'a circumferential aperture 19 between it and the bottom surface through which the air discharges. 20V is a bottom plate detachably secured' to the base 1 and-designed to inclose the lower -fan 13 within the base.
21 are suitable screw bolts extending `thr(' u,(, ;h lugs 22 secured to the casing 23 and having the aperture 27 therein. 'The aperture 27 registers with the aperture 24 in the upper fan casing 16 and the aperture 3 registers with the aperture 25,in the lower fan casing 18. 28 isa screen of wire mesh suitably secured to the partition 26 above the aperture 27.
29 is a beading secured to the interior of the casing 23 near the top of the same and supporting the dust bag 30 having a bead or gasket 31 extending around the top of the same. V
32 is the cover of the casing 23 having the cup-shaped partition 33 formed in the top thereof, the partition 33 having the central aperture 34 therein. 35 is a sight glass in the top of the cover and 36 is an aperture in the side of the cover designed to receive the upper end of the hose, the lower end thereof being connected to the cleaning tool.
37 are threaded bolts pivotally secured to lugs 38 which are secured to the side ofthe casing 23 and have thumb nuts 39 thread@ thereon.
40 is the handle of the cover, suitably secured thereto and having the slotted projections 41 extending over the edge of the cover. The bolts 37 are inserted into the slots 42 inthe projections 41 and thus hold the cover-securely to the casing. v
rlhe operation of the cleaner is as follows: The suction produced by the fans 12 and 13 draws the dust and dirt up through the cleaning tool and hose (not Shown) into the cover 32, through the aperture 36 and down through the aperture 34 in the partition 33, and thence tinto the dust bag 30 where the dust and dirt are separated from the air. rlhe screen 28 prevents the dust bag 30 being sucked down into the fan 12. The air is then drawnvdown around the screen and through the aperture 27 in the partition 26 l and into the fan 12 through the aperture 24.
lt is discharged from the fan 12 downwardly against the motor 8 through the aperture 17 and from thence is deected toward the center of the top of the base 1 by the blades 5 and then is drawn down through the aperture 3 through the aperture 25 inthe top of the fan casing 18 into the fan 13 from whence it is discharged out through the aperture 19 in the fan and out of the machine through the discharge aperture 7. Thus the motor is effectively cooled by the air being drawn down against it.
What l claim as my invention is:
1. ln a vacuum cleaner the combination with an electric motor having its armature axis vertical and the shaft extending above and below the motor, of suction fans secured to the upper and lower ends of the shaft casing extending over thc fans and revolving therewith, said casings having central inlet apertures therein, the upper fan casing havhaving a vertical circumferentially extending outlet aperture and the lower fan casing having a vertical circumferentially extending outlet aperture, and a base portion supporting the motor and having a top portion formed thereon with a central aperture registering with the central aperture in the lower fan' casing, means on the top of the base for de'liecting the air toward the central aperture therein, said top of the base being situated between the motor and the lower fan.
2. In a vacuum cleaner the combination with an electric motor having its armature axis vertical, and the shaft extending above and below the motor, of suction fans secured to the upper and lower ends of the shaft casing extending over the fans and revolving therewith said casing havin central inlet apertures therein, the upper an casing having a horizontally circumferentially extending outlet aperture and the lower fan casing having a vertical circumferentially extending-outlet aperture, and a base portion supporting the motor and having a top portion formed thereon `with a central aperture registering with the central aperture in the lowerfan casing a circumferential wall and suitably curved blades, -both formed on the top of the base for detlecting the air towardl the central aperture therein, said top of the base being situated between the motor and the lower fan. .A
In witness whereof I have hereunto set my hand in the presence of two witnesses.
