VACUUM-CLEANER.

Specication o! Letters Patent.

Application and June 9, 1913. serial No. 772,463.

To all whom it may conf-ern Beit known that I, CHESTER H. BEACH, a citizen of the United States, and resident of Racine, in the county of Racine and State of Wisconsin, have invented certain new and useful Improvements in Vacuum-Cleaners; and l do hereby declare that the following is a full, clear, and exact description thereof.

My invention has for its object to provide a simple, economical and light-weight vacuum cleaner of miniature type for hand use, the same being particularly designed Vto take the place of whisk-brooms or analogous devices for cleaning clothing, or'various articles not including floors" or carpets, as, for example, the felt surfaces of game tables, and to meet the various requirements as to the scope of the cleaner I also provide certain detachable members that can readily be interchanged by the user.

With the above objects in view the invention consists in what is lherein shown, described and claimed.

In the drawings Figure 1 represents a side elevation of a vacuunrcleaner embodying the features of my invention, parts of the machine being broken away and in section to more clearly illustrate structural features, which sectioned parts are indicated by line 1 -71 of Fig. 2, and Fig. 2, an inverted sectional plan view of the same, the section being indicated by line 2 2 of Fig. 1.

Referring by characters to the drawings, 1 represents a housing containing an electric motor 2, the said housing being provided with a grip-handle' 3 having a tubular stem 3' that. carries the usual feed-wires 4 for, supplying energy to the motor. lThe shaft 2 ot the motor projects through the lower face of the housing and also through an eccentrica'lly disposed boss 5 of a circular casing 5, 'the same being in the form of an inverted cup having its lbottom wall secured to the lower face of said housing by bolts 6. The bolts pass through apertures ini the housing and engage feet 6', the same being secured to the bottom wall 5" of the cup-like housing by screws as shown. The mouth of the casing is provided' with an inturned lip 5"', which lip extends around the casing edge being concentric with the motor axis, and` forms an air intake opemng. The casing 1s also provided with an air discharge nozzle 5"", which nozzle extends at a tangent to the side wall of the casing. Y

'operatorV or others.

Fitted over the casing boss 5 isa cupped hub 7, a flange of which hub carries a fan `latentes apr. 21,1914.

disk S'that. has secured toits lower face a l series of 'depending vanes 9, the disk and Yanes constituting a fan, The hub 7 of the fan is secured to an extension of the motershaft 2' by set-screws and is provided with a reduced shaft-extension 7';

Loosely mounted upon the shaft etxension T' is a spider 10, the arms of which spider constitute heads for depending brushes 10' the working or brushing `faces of whichbrushes vnormallyV project slightly below the plane of the casing mouth. The br'ush spider is capa-ble etA longitudinal yield in opposition to tension of acoiled'spring 11 that surrounds the shaft extension 7 the said Spring being interposed between ashoulder ofthe fan hub and upper face of the spider, whereby said spider is seatedagainst the flanged head, of a set-screw 12, which set-screw is in threaded union with-the motorshaft extension. Thus byadjusting the set-screw 12 the working or brushing face of the brush lnay be regulated with rel-ation to the mouth of the fan-casing.

The discharge nozzle 5" has detachably secured thereto a thimble 13, the thimble forming a rigid receiving mouth for a p01- `ous dust-collecting sack 14, which is attached thereto. The opposite end ofthe sack or separator is left open for the purpose of emptying the deposits of dust that may accumulate therein and vin its operating position the open end is closed by a: spring-clip 15, which clip is suspended from a'hook that extends from the handle stein 3.

In the operation of the cleaner as exemplitied above, the operator gra-spe the machine in one hand and directs the same over the surface or clothing either of the Current being supplied to thev motor, it is apparent that the fan will be rotated and its vanes which projectbetween the spider arms will cause simultaneous rotation of the brush, The flanged mouth of the fan casing in the meantime .is slowly moved over the surface to be cleaned. ThusF the dust, is positively loosened from the fabric -and coincident thereto the partial vacuum producedcauses the dust-laden air to be drawn into the casing and discharged therefrom into the separater sack, from which point the air is exhausted to atmosphere through the pores of the latter. 4It is also obvious that in operation the brush bristles are pressed into contact with the surface to be cleaned'by lthe coiled spring 11, the said lbrush being capable of slight rise and fall as it follows the contour of the surface over which the shellmouth travels. The cleaner may also be utilized for various other` purposes wherein it is desirable` to rst subject the material to av positive brushing operation,

as, for example, it may b e utilized for cleaning animals or various surfaces where hand manipulation is desirable. It is also apparent vthat by the peculiar attachment of the spider brush in connection with the fan, as shown in Figs. l and 2 of the drawings, said brush vcan bereadily removed when it is desired to utilize the machine as a. suction cleaner only and that the pressure of the brush can be regulated by adjusting said brush up or down.

I claim:

1. A vacuum cleaner comprising a housing having a handle extended therefrom, a motor mounted within the housing havingashaft extension, an inverted cup-like casing secured to one face of the housing through which the shaft extensionl protrudes, a brush-carrying spider` mounted upon the shaft extension and revoluble therewith, and means for permitting longitudinal yield of the spider upon said shaft extension.

2. A vacuum cleaner comprisin a housing having a handle extending t erefrom, a motor mounted within the housing having a shaft extension, an inverted cup-like casing secured. to one face vof the housing through which the, shaft extension protrudes, a fan secured to the shaft extension-having vanes extending downwardly, a spider loosely mounted upon the shaft extension, the spider being disposed in the path of travel of the fan vanes, bristles extending from the spider having their brushi ing ends normally exposed slightly below the plane of the mouth of the easing, and a coiled spring surrounding theshaft extension adapted to exert pressure against the spider.

3. A vacuum cleaner comprising a housing having a handle extension therefrom,

.a motor mounted within the housing hav- `ing a shaft extension, an inverted cup-like casing secured to one face of the housing through which the shaft extension protrudes, afan secured to said shaft extension having vanes extending downwardly, a spider mounted upon the shaft extension, means for causing the spider to revolve with the shaft, bristles carried by said spider, a coiled spring surrounding the shaft exten- .sion adaptedrto exert downward pressure upon the spider, and adjustable means carried by the aforesaid shaft extension for limiting movement of said spider.

4. A vacuum cleaner comprising,l a housing having a handle extending therefrom,V a motor mounted within the housing having a shaft extension, an inverted cup-like casing-depending from the housing through which the shaft extension protrudes, a fan secured to the shaft extension having vanes extending downwardly, a spider loosely mounted upon the shaft extension, the spider being disposedin the path of travel of the fan vanes, bristles extending from the spider having their brushing ends normally exposed shghtly below the plane of the mouth of the casing, and a spring carried by the aforesaid shaft extension adapted to exert pressure upon the spider.

In testimony that I claim the foregoing I have hereunto set my hand at Racine in the county of Racine and State, of Wisconsin in the presence of two witnesses.
