Application filed May 6, 1920. Serial No. 379,284.

[To all whom it may concern:

Be it known that I, IRA J. OWEN, a citizen of the United States, residing at the city of Grand Rapids, county of Kent, State of Michigan, have invented certain new and useful Improvements in Suction Cleaners, of

which the following is a specification.

Thls invention relates to lmprovements 1n suction cleaners. The invention relates par.-

' details and economies of construction an ticularly to the nozzle portion and the conduit and connections therefrom to the suction fan. 7

The object of the invention is to facilitate the flow or inrush' of air into .the nozzle and to facilitate the passage of the same to the fan or dust collector. I

Objects of the invention pertaining to operation will definitely appear from the detailed descriptionto follow. I the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and the suctlon pointed out in the claims.

A. structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:

F1 I is a perspective view of my improved nozzle structure in connection with 7 parts being broken away.

Fig. III is a detail side elevation view of .and rear walls being the structure.

Fig. IV is an enlarged detail vertical elevation view, partially in section on line 4-4 of Figs. II and V. a

Fig. V is a reduced vertical detail sectional elevation view taken on line 5+5 of Fig. IV. I Fig. VI is an enlarged detail sectional elevation view of the end 0 'eninIg .in the nozzle taken on line 6-6 of ig. I I.

In the drawing all the sectional views are taken looking in the direction of the little arrows at the ends f the section lines, and similar reference characters refer to similarparts throughout the several views.

Considering the numbered partsof the drawing, 1 is the nozzle structure generally secured to theside of the suction fan case 2 which delivers into the dust collector bag 01 other device 3, seen in Fig. I. The nozzle is accomplish P CllIlIlg 1t to the fan case 2 or front of the fan of a suction cleaner, other.

wide. This constructlon at in use.

. built out into a broad intake portion 4 at the This is made within the nozzle part and the walls are curved and rounded as shown to mlnlmize the friction. l

This nozzle portlon is made up of a main d block 8 which is tapered downwardly as seen in Fig. IV, and provided with a front late 10. A flange 11 is provided for sevacuum cleaner.

' I have described my improvement as particularly applied to suction cleaners having a horizontal motor andfan. It Is very ef-' fe'ctive for these because all of the dust .and debris collected must be carried up a considerable distance from the floor and this device does the same very effectively.

Also, by the Venturi form of the outer end of the nozzle,a strong current of air enters the nozzle mouth at each end and sweeps across a comparatively narrow section of the carpet em raced wit-hm the nozzle, the nozzle opening between the front about one-half inch eachfend of the nozzle is of thehighest advantage because s strong a current of air is created that it readily collects dust and loose particles from corners of the floor next the baseboard. Also, the structure cleans a swath, so to speak, considerably wider than the nozzle when it 1s The entry'of a strong current of air at the end is of very highest consequence because it forcibly carries awayany dust that is disturbed by the comparatwely at once collects and small circulation of air under the front and rear edges of the nozzle, greatly facihtating the action of the nozzle and lint from any carpet, or even from a bare floor. The nozzle is adjusted in use three thirty-sccondsof an inch or more above the surface to be cleaned. The Venturi action I and collects all dust CARPET SWEEPER therefore insures effect to the suction or inrush of air for the entire width of the nozzle.

I have described my improved nozzle structure for suction cleaners in its most approved form. I desire to claim the same specifically as'here illustrated and also. to claim the same broadly. I have shown a specific form of a nozzle especially adapted for use upon hand operated vacuum cleaners in the application filed concurrentlay herewith, The form here shown is especially adapted for power cleaners.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1.' .A nozzlestructure for suction cleaners having a broad intake mouth with notched openings at the end, curved exteriorly and aving a contracted portion at a little distance from the end to secure Venturi tube action, the main passage being also conand having an expanded discharge portion to secure Venturi tube action, the contracted walls of said passai being on curved lines,

2. nozzle structure for suction cleaners having a broad intake mouth with notched as specified. p,

openings at the end, themainpassage being contracted intermediately and havin 'an expandeddischarge portion to secure enturi tube action, the contracted walls of said passage being on curved lines and the front and. rear walls being tapered to the intake, as specified. p 1

3. A nozzle structure for suction cleaners aving a broad intake mouth with notched openings at the end, the main passage being contracted intermediately and having an expanded discharge portion to secure Venturi tube action, the contracted walls of said passage being on curved lines, as specified.

4. A nozzle structure for suction cleaners having a broad intake mouth with notched openings at the end, curved exteriorly and having a contracted portion at a little distance from the end to secure Venturi tube action, as specified.

' In witness whereof, I have hereunto set my hand and seal in the presence of two witnesses. v
