FRANK W. FINKHOUSEN, OF FORT WAYNE, INDIANA.

To all wlwm t may comem:

Be it known. that 1, FRANK HoUsEN, a citizen of the United States, re siding at Fort Wayne,

VACUUM CLEANER.

Application led February 28, 1921.

FINE- in the county of Al- 5 len, State of Indiana, have invented certain new and useful ements in Vacuum Impro Cleaners; and do hereby declare the f ollowing to be a fu tion of the invention,

others skilled in tains to make and .use the ll, clear, and exact descripsuch as will enable the art to which it appersame.-

The object of the invention is to provide a motor actuated vacuum cleaner suitable particularly for use in removing dust from clothing,l tapestries, designed with a view u aldirection and positioning thereof with reference to the surfaces to fabrics and the like and to facilitate the maneffecting the detachment and removal of accumulations of of injury to the fabric the relative delicacy thereof more to provide a device dicated which in matters dust with the minimum risk or pile regardless of and furtherfor the purpose inof construction and the assemblage' of parts is simplified to the utmost extent with facility of operat due consideration for ion and removal of the collectionof dust made in the course of the operation of the mechanism; and with these objects in view, construction and which a preferre the accompanying the invention consists in a f in the brush chamber.

combination of arts o d embodiment is s own in drawings wherein;

Figure 1 is a side view of the cleaner. Figure 2 is a longitudinal sectional view of the same.

metal such as aluminum having a fan chammeans of an openber 16 communicating by directed conveyor ing 17 with a forwardly 18 which communicates at its front end with a brush chamber 19 having an open face Awhich is fitted with a removable plate 20 adapted to b e sprung or snapped into place for facility in removal and having'an outwardly convexcd oi' arcuate form as indi cated clearly in Figures 1 and 2, the'chord of the arc being transverse to the length of the implement. A

The plate is provided at its front edge with an u wardly directed flange 21 designed to lie in contact with the inner surface of the front wall of the brush chamber,

and is furtherpi'ovided at its rear edge with for contact with the rear 'the brush chamber and is further proears 22 and 23 edge of the opening in vided at its rear edge ranged to project inwardly and lie in terminal engagement with the inner surface of the lower or front wall of the nozzle as a means of locking the guard removably in place in spanning relation with the opening Said plate is further provided with terminal upstanding ears 25 designed to lie in contact with the inner surfaces of the end walls of the brush chamber with an ear 24 arand fitted with" pintles 26 for reception by the terminal bearings 27 of the brush core 28 which carries the bristles 29. Obviously when the plate is ositioned in the nozzle the ears 25 are held in position to prevent the dismounting of the brush whereas after the removal of the plate the ears are free to be sprung outward to disengage the pintles thereof' from the bearings of the brush to release 'and allow of the removal of the latter for cleaning purposes and the like. litwill thus be seen that ly detachable bearing members, which are normally held in engagement by` the end walls of the brush chamber.

'Attached to the upper side or back of the casting forming the nozzle and in registration with an opening 30 formed therein, is

, removal of the cap csh the cylindrical, wall 31 of a motor casing, secured in place, for example, by screws 32 and litted with a removable domed cap 33 having a; screw joint connection 34 with said wall, and fitted upon the motor shaft 35 which extends downward into the fan chamber 16 is a sleeve hub 36 carrying the fan 37 and provided at its lower end with a pulley 38 connected by a belt 39 with a similar pulley 40 on the core of the brush. The lower wall of the conveyer 18 is also preferabl provided 'with an opening 41 tted wit a removable cap v42 adapted to be sprung into place and hence removable to give access to the 'pulley 38 and provide rorthe proper engagement of the belt therewit '.Ilhe side walls of the handle member of the casing are provided with slots 43 forming vents for the relief of air pressure in the apparatus due to the action of the suction fan, while the dust receptacle or bag 13 which is open at both ends and is designed for the reception of the dust drawn into the nozzle through the slots of the plate serves to retain the dust while permitting the escape of the air. The dust bag or receptacle is provided with expansion springs 44 at its extremities for engagement with annular vgrooves or seats 45 in the inner surface of the,wall of the' handle to insure the passage of the dust thereinto, and from which the dustpmay be discharged by the 14. Obviously the bag or receptacle ,may be readily removed for thorou hY cleansing, simply by the contraction o the retainin springs or bands, and such removal is facilitated bythe fact that the handle member of the casing is preferably enlarged toward its rear end and the bag or receptacle is correspondingly tapered as will be obvious by reference to Figure` 6. The construction of the dust collecting means herein described and forming a part of the erein described vacuum cleaner, forms the subject matter of a separate divisional application, filed July 26, 1922, Serial No.

What is claimed is:

1. A vacuum cleaner having al nozzle opening, downwardly, a plate litted inl spanning relation with the nozzle opening, the said plate being formed with ears carrying .pintles, and a brush removably fitted upon of the walls of the nozzle adjacent to said opening.

3. A vacuum cleaner having a nozzle Ainernber provided with a dust receiving opening, a fan mounted in the nozzle, a transversely arcuate plate removably tted in spanning'relation with said opening, and a rotary brush mounted upon the 'plate and having operating connection with said fan, said plate having inwardly-extending laterally yieldable ears havingpintles for receiving terminal bearings of the brush.

4. A vacuum cleaner having a nozzle opening downwardly, a transversely arcuate plate having a dust receiving opening andremovably tted in spanning relation with the nozzle opening, said plate being formed with a pair of inwardly directed, laterally yieldable ears having pintles, and a rotary brush having its bearings mounted in the said pintles.
