Description

1927' M. H. SPIELMAN VACUUM CLEANER Fild Sept. 29. 1922 2 Sheets-Sheet 1 O 4 1 D Jan 927 M. H. SPIELMAN VACUUM CLEANER I Filed Sept. 29. 1922 2 Sheets-Sheet 2 flange 43 integral with the motor housing to prevent the ingress of dust or other extraneous matter to the motor parts. The upper end of the motor is completely enclosed y an end member l5 comprising a shaft bearing and brush carrier.

The movement of the air is as follows The air is drawn through the nozzle opening 18 upwardly to an opening formed 1n the bottom wall 30 of the fan chamber and is forced from the fan chamber upwardly throu h an opening 46, which is provided by romittmg a portion of' the frame flange and motor housing flange 16 as illustrated in Figs. 2 and 4 respect-ively, into the filtering bag 15. The position of the shaft of the motor/and the fan relative to the opening 30 iis such, thatthe center of the, shaft is substantially coincident with the center of the opening 30. As shown in Fig. '3, the

- proportioning of'the nozzle portionof'the frame '10 andithe fan chamber walls is such that the motor is supported with the motor shaft slightly inclinedto the plane of the nozzle opening; the purpose of this arrangement being to properly balance the weight of the entire device relative to the handle 20 -and the nozzle, whereby the operator or user may dexterously manipulate the cleaner when applying the nozzle to various objects, such as upholstered furniture, clothingand the like. It is to be understood however, that this result may be obtained in a variety of convenient arrangements which would come within the scope of my invention..

The filtering bag 15 may be secured to the cleaner frame in any suitable manner. l

have found however, that a very eificient and convenient way of removably'attachlng the bag to the gleaner. is to provide a gatheringcord which may be strung through a lower hemmed end 15 of the bag to permit the drawing or gathering of the open end,

of the bag upon the grooved flange 14 of the L frame, the groove 1 9* being of suficient size to receive the gathered edge'of the bag and thus prevent its being frame when inflated.

It will be noted that l[ have afixeol the hand-late the frame in such relation to the nozzle opening that the center line of the handle will lie in a medium plane passing through the nozzle. This arrangement greatly facilitates the easy manipulation of the device by the operator. A hand applied vacuum cleaner constructforced away from the I ed in accordance with the foregoin descrip thereof.

tion will be found to have many a vantages both in the manufacture and in the use The novel arrangement of the motor housing upon the frame of the device whereby the motor is disposed within the filtering bag afiords a very compact con struction which permits such arranging of the nozzle relative to the'handle sothat'the aeiaeeo I weight of the device may be properly balanced relative to the handle.

A further advantage of this arrangement is that the elongated nozzle opening may be efiiciently used as it extends in a common direction with the handle whence the nozzle may be readily manipulated in all'directions; the nozzle at no timebeing obscured from the vision of the user. The provision of the motor with a. dust-proof frame or housing whereby it. may be-disposed within the'filtering bag has the further advantage in that the air forced into the filtering bag circulates about the housing and servesv as a motor cooling medium. If desired, the motor housing frame may comprise aluminum castings to further decreasethe weight of the device.

The removal of dust-and other extraneous a nozzle portion having an elongated rectangular opening, the nozzle portion depending below the fan housingortion, a handle rigidly secured to the nozz e portion of the frame and extending in a plane longitudilUU- nally bisecting the nozzle opening, a brush r1g1dly mounted within the o ening and extlendin to the mouth thereo ,a suction fan suspened-within the fan housing, a motor therefor, a motor housing completely enclosing the motor, said motor housing being mounted on the frame in such a manner that the axis of the motorshaft lies in said plane and a filtering bag completely surrounding the motor housing and detachably secured to the frame. v

2. In a suction cleaner, av frame member comprising a nozzle portion, and a fan housing portion, an annular flange extending up war ly from the fan housing portion a lilterin bag attached to said flange, a fan dispose within the fan' housing, an inwardly extending flange forming an incomplete annulus and rigid with the frame, theopening 12 0 in saidlast named flange forming an air assage between the fan housing and the ag, a motor for the fan, and a motor housing secured to tlre inwardly extending flange and substantially covered by the filtering bag.

3. In a vacuum cleaner of the character described, the combination of a frame having a nozzle portion depending from an annular fan housing portion and having a rectangular opening, said frame having a pnneiaeeo titioning wall between the nozzle portion and the fan housing portion provided with a centrally disposed opening, a tan, a radial flange formed to extend inwardly in the annular portion and spaced a art from said partitioning wall a distance 3 ightly greater than the width of the fan, a motor, a housing therefor completely enclosing the motor,

the housing being provided at the fan end.

thereof with a flanged portion adapted to engage the annular flange of the casing, a second'annular flange extending upwardly from the first named flange, and a filtering bag removably secured to said last named flange.

4. In a vacuum cleaner the combination of a frame having a nozzle portion with a rectangular opening and a cylindrical fan casing portion, a partitioning wall between said portions provided with a centrally disposed opening, a fan positioned therein with the axis thereof extending in a plane longitudinally bisecting said openings, a motor for driving the fan, a motor housing completely enclosing the motor, the fan being webbed to comprise closure means for one end of the housing, a radial flange extending inwardly in the fan casing portion comprising a supporting means for the motor ameter than the motor housing whereby an air passageway isprovided tron] the tan casing exteriorly of the motor housing,

5. ln a vacuum cleaner of the character described, the combination of a frame comprising a nozzle portion and an annular tan ousing portion, a partitioning wall between said portions, said artitioning wall having a centrally dispose opening relative to the annular portion, the nozzle portion being ofiset relative to the annular portion, said centrally disposed opening being at one end of the nozzle portion, the annular portion being provided with an inwardly extending flange, the relation of the nozzle and flange being such that the plane of the nozzle opening and the plane of said flange converge whereby a motor housing may be mounted upon the flange with the center line of the motor lying in a plane which bisects the annular portion and the nozzle portion the center line being disposed at an angle relative to the mouth of the nozzle.

In testimony whereof, I hereunto afiix my signature.
