SUCTION SWEEPER Filed Sept. 11, 1951 ff -m Patented Jan. 8, 1935' SUCTION SWEEPER Otto Schlingplsser, Halle-on-the-Saale,

Germany Application September 11, 1931, Serlal No. 562,385 In Germany September 24, 1930 3 Claims.` (Cl- 15-17) u This invention relates to suction sweepers and has for its principal object to devise a construction which is properly dimensioned and arranged to permit its use as a toy for children which may 5 be conveniently and of a child without any fatigue and which in addition is likewise suitable for use as a practical utensil for domestic and other purposes. There is a decided demand, especially for industrial purposes, for a suction sweeper which permits of being used conveniently and effectively by hand without any cumbersome installation work and any special auxiliaries such as a driving motor.

According to my inventionl this is accomplished by using a fan and a rack-and-pinion drive associated therewith easily handled by the hand by mounting either of these devices within a casing of its own', by arranging the two casings so obtained parallel to each other,

by providing an actuating knob for the rack-4 and-pinion drive, said knob extending out of the respective casing in a manner permitting to be depressed by one finger of the hand by which the suction sweeper as a whole is being held during use. For this purpose the two casings are so-'dimensxoned be gripped by four that they may immediately fingers or a bail or handle may be provided adjacent the rear wall of the casing for the rack-and-pinion drive, said bail or handle extending parallel to the said rear wall-y and likewise permitting to be gripped by four fingers. 4 The last-mentioned arrangement has been found to be especially suitable for the practical actuation of a whole.

the rack-and-pinion drive and the manipulation of the suction sweeper as A further feature of my invention consists therein Vthat I provide a straight rigid' suctionpipe connected to the front wall of the casing for the fan co-axially therewith. By so arranging the suction-pipe there will be the possibility of using the device also in case the place to be treated by the 'suction sweeper culty or positioned hand.

On account of the is only accessible with dimat some distance from the aforementioned'bail or handle the suction sweeper may be firmly and conveniently gripped by the hand, at the same time permitting the orifice at the front end of the suction-pipe to be easily applied to any place to be cleaned by the suction sweeper.

In the accompanying drawing I have represented two examplesv of construction of my new suction sweeper in a longitudinal view with the two casings in section.

Within the casing a there is mounted the fan b.

while the drive for said fan is mounted Within a second casing c immediately adjacent to said former casing, said drive consisting of a rackand-pinion device, the rack d thereof extending towards above and out of the casing and termi- 5 nating into an actuating knob e. By depressing the knob e and therewith the rack d against the action of the spring f the gear-wheel g and by way of a further pinion p as shown the fan b may be rotated. 'I'he spring f serves for the purl0 pose of causing the rack d after being depressed to always return into inoperative position as 4shown in both figures of the drawing.

While the casing a is of a conformation to accommodate the rotating fan b, the casing c is of 15 the form of an oblong box having proper dimensions permitting to be held conveniently from the side with four fingers, while the fifth finger, preferably the foreiinger, may be used for depression of the knob e. ously with the casing b the casing a also may be gripped by four fingers. f- Y In the construction shown in Fig. 2 the rear wall of the casing c may be provided with a bail or handle i which is of proper conformation to permit of being conveniently kept with the four fingers of the hand, while at the same time the thumb may be used for operating the driveby depressingthe knob e. The construction shown in Fig. 2 will permit a still better grip to be ex- 30 erted by the hand than is possible with the construction shown in Fig. 1.

There is further provided a straight rigid suction-pipe i extending towards the-front co-axially adjacent the casing a and the fan b, said suction-pipe carrying in known manner an orifice lc at its iront end. A collecting bag m is further connected to the casing a by means of a short connecting pipe l, said collecting bag serving for the reception of the dust which is drawn in by the suction-sweeper.

The suction-pipe i may be of such length that it will be possible to apply the suction sweeper to places which are positioned at a relatively great distance therefrom. A further support which is necessary in this case for the suction sweeper will be given by the orifice k of the suction-pipe.

I claim:

1. A vacuum cleaner comprising a suction fan, a housing forsaid suction fan, a shaft for said suction fan, a gear chain for driving said shaft, a second housing for said gear chain positioned parallel to said first housing and having a com-` mon wall with said first housing, the shafts of Eventually, simultanezo said gear chain and said suction fan shaft being mounted in said common wall and the exterior wall of said second housing, a rack for actuating said gear chain having a portion extending to the exterior, of said second housing, a spring for returning said rack after said rack has been depressed to actuate said gear chain and a nozzle secured to said suction fan housing.

2 A vacuum cleaner comprising a suction fan, a housing for said suction fan, a shaft for said suction fan, a gear chain for driving said shaft, a second housing for said gear chain positioned parallel to said rst housing and having a coin-- mon Wall with said rst housing, the shafts of said gear chain andsaid suction fan shaft being mounted in said commonwall and the exterior wall of said second housing, a rack for actuating said gear chain having a portion extending to the exterior of said second housing, a spring for returning said rack after said rack has been dehousing, a rack for driving said gear chain and a spring for returning said rack to its initial position after operating said gear chain, said spring having one end secured to said rack and the other end secured to the interior of said second housing and a nozzle connected to said first named housing.
