Description

A. BODE VACUUM CLEANER Jan. 21, 1930.

Filed June 29. 192 8 ai j m ON W M 2 m Z 1/ 5 Z Ill Patented Jan. v21, 1930 PATENT; OFFICE ADELE ZBODE, OF HAMBURG, GERMANY VACUUM CLEANER Application filed June 29, 1928, Serial No. 289,254, and in Sweden and Czechoslovakia April 18, 1927.

I have filed applications in Sweden and disposed immediately below a vertically mounted rotary suction fan, and embedded within a housing whose sides are bent to form rearwardly extending passages from the front of the suction plate to the rear thereof. A still further object of the invention is to provide an improved motor driven vacuum cleaner formed with a plurality of spaced air inlet passages, whereby air and dirt may be sucked through said passages and discharged into the dirt collecting bag adjacent the motor driven impeller.

Other objects will appear as the description proceeds.

In the accompanying drawings which form a part of my application:

Figure 1 is a sectional view taken on the line 11 of Figure 2.

Figure 2 is a side elevation of the vacuum cleaner, showing-the same partly in section.

Figure 3 is a perspective view of the vacuum cleaner, showing a portion thereof in section.

Like characters of reference are used throughout the following specification and the accompanying drawings to designate corresponding parts.

My improved vacuum cleaner comprises a housing 1 which supports a centrally located motor housing 2, in which a suitable motor is received. The lower portion of the motor housing 2 is extended outwardly to form a fan housing 3. A transverse partition plate 4 separates the motor housin from the fan 59 housing and serves as an additional bearing having a corrugated suction plate for the shaft 5 of the vertically mounted suction fan 6.

A corrugated suction plate 7 is mounted in the housing 1, with the corrugations extending transversely thereof. Air passages 8 are formed through the forwardly extend- .ing surfaces of the corrugations, so that air and dirt may readily be sucked through the same. The housing 1 is rounded at its opposite sides and forms the rearwardly extending air assages 9, the purpose of which will later be escribed.

A rubber brush 10 will be removably secured at the front end of the housing 1, and may be notched as at 11, and serves to draw the hairs or threads as they lie free on the surface, and roll them up so that they may be readily drawn into the cleaner.

A guide roller 12 is supported between the brackets 13 at the rear of the cleaner, in such a manner that the cleaner may pivot on the I same.

The handle 14 is removably secured at 15 to the motor housing 2. A dust collecting bag 16 is supported between the handle I l and the discharge outlet 17 connected with the fan housing 3.

The mode of operation of my improved vacuum cleaner will now be described. When the motor is in operation, the fan 6 will draw the air and dirt up from below the corrugated suction plate, and up through the air passages 8 formed in the forwardly extending portions of the plate and be discharged through the discharge outlet 17 into the dust collecting bag 16. The air and dirt which passes through the passages near the back of the plate will be delivered immediately to the dust bag, but the air and dust entering the forward passages will be discharged transversely along the corrugations on the upper side of the plate and back through the side passages 9 and then sucked by the fan to the outlet 17 and forced into the dust bag.

It will be obvious that many minor changes in detail of construction may be resorted to without departure from the spirit of the invention.

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

1. A device of the character described comprising a housing, a perforated corrugated suction plate carried thereby, rearwardly extending passages formed in said housing at the ends of said plate, a motor 'driven fan disposed above said plate and sup orted on said housing, and a dust collecting ag in communication with said fan.

2. A device of the character described comprising a housing, a perforated corrugated late carried thereby, said perforations being ibrmed in the forwardly and upwardly extending flanges of the plate, rearwardly extending passages formed in said housing at the opposite sides of said plate, a motor driven fan disposed above' said plate and supported on said housing, a brush removably carried at the forward edge of said plate, a bearing roller carried at the rear of said plate, a dust bag in communication with said fan, and a handle for moving said device.

In testimony whereof I afiix my signature.
