CANISTER-TYPE VACUUM CLEANER Filed Oct. 18; 1957 3 Sheets-Sheet 5 Lye arm: Geqzje M Kelly This invention relates generally to cleaning apparatus and more particularly to, a canister-type vacuum cleaner, terminology which is used to describe an upright-type of a so-called tank-type vacuum cleaner. i
It is an' object of the present invention to provide a canister-type vacuum cleaner having improved means for mounting and cushioning a motor fan unit.
Yet another object of the present invention is to proconnecting means for a canister-type vide improved filter vacuum cleaner.
A further object of the present invention is to provide improved coupling ,rrieansbetween the housing and a conduit used in associationv/ith the cleaner. Many other advaiitages, features and additional objects of the present invention will become rnanifest tothose versed in tlie art uponinaking reference was detailed ,escription whiclrfo llow'sland the accompanying sheets or drawings in "which a preferred structural embodiment of a canistertype vacuum cleaner incorporating the principles ofthe present invention is shown by way of illustrativeexampleyff o rthe drj ings:* ""Figurel isa broken elevational view with parts shown in cross-section illustrating a canister-type vacuum cleaner incor iorating'ithe principles of the presentinventidh; Q Figurez is a fragmentary explodedview illustrating additional details of construction of the present invention and particularly withrespect to the motor mounting improvements thereof; 1 l

An annular ring of soundfdeadenin'g insulating material such as is shown at '19 s fa tened t tbs i l r n of t e d walls housing constitutes asheet form member which has a generally inverted cup shape configuration including a top wall 20 and depending side wall portions 21 terminating in a radially outwardly extending flange fan unit within the casing 39.
2,8b832i Patented Jan. 13, 1959 22 adapted to be positioned in overlying adjacency tothe flange 17 of the lower housing 12. A handle for carrying the machine is shown at 23 and is fastened to the top wall 20 by suitable fastening means 24. e
A generally horizontally disposed partition or wall 26 extends across the interior of the housing or casing 13 between the upper housing Hand the lower housing 12, thereby todivide the interior of the casing 13 into a dirtseparating compartment'2'7 and an air discharge or outlet compartment 28.
More specifically, the partition or wall 26 constitutes afsheet for member of a generally annular configuration having an outer peripheral edge 29 of greater diameter thanthe diametral dimension of the side walls 16, thereby to overlie andabut'tingly engage the flange 17 of the lower housing 12. t m
The partition or wall '26 is embossed, thereby toj-provide a generally arching portion 30 radially inwardly of the peripheral edge 29 and terminating in a vertical shoulder 31 which is oflset to provide the side wall of an annular recess 32. Extending radially inwardly from the side wall portion 31 is a horizontal wall portion 33 which terminates in an offset inner rim 34 surrounding the edge of a centrally disposed opening 36. The embossed shape of the partition or wall as endows the sheet form member with additional rigidity and strength. The partition or wall 26 is preferably firmly assembled to the lower housing 12, for example, by spot-welding the peripheral edge 29 to the flange 17 at various circumferentially spaced points.
A motor fan unit indicated generally at 37 has: an electric motor 38 drivingly connected with a fan unit enclosed within a casing 39, the casing 39 being of larger size than the motor end of the unit 37, thereby to provide a radially extending wall 40 terminating in a rounded "corner 4-1 which is of a dimensional extent slightly larger than the diametral dimension of the opening 36 formed in the partition or wall 26. The casing further includes a circumferentially extending side wall 42 and an endwall 43. i
As is shown in Figure 1, suitable conductor wires 44 are connected electrically to the motor 38. The wires 44 are connected toa conventional sheathed cord 46 which passes through the side wall portions 16 of the lower housing 12 via an appropriate gasket 47, therebyto facilitate electrical connection to a domestic supply source of electricity for energizing the motor 33 and actuating the Accordingto the principles of the present invention, the motor fan unit 37 is assembled with the lower housing 12 and in the partition or wall 2 6 by the mere simple act of inserting the motor portion 38 through the opening 36 so that the casing 39 will overlie the inner rim In this connection, a resilient gasket 50 is provided which has a generally cylindrical pilot portion 51 having an outer diameter provided by aside Wall 52 of the same dimension as the opening 36.
A supporting portion 53 extends radially outwardly from the pilot portion and overlies and seats against the rim 34. The support'portion 53 is provided with an upstanding flange 54. which extends in axial direction generally parallel to the pilot portion 51, but spaced concentrically outwardly thereof. The inner surface of the gasket fill is curved as at 56 to conform to the configuration of the rounded corner 41 of the casing 39.
Thus, in assembly, the gasket 50 is merely inserted in place in the opening 36 of the partition or wall 26, whereupon the motor fan unit, having been electrically connected'bymcans of the quick fastening couplers57 (Figure l), is conveniently set down in place ontop of the gasket 50. Theupstanding flange 54 of the gasket 5t] closely embraces the side wall 42 and the motor pass through one of prises an end wall 59 and side wall portions 60 which depend therefrom, there being further provided an outwardly projecting flange 61 suitably apertured at circumferentially spaced points as at 62.
aeeasai The horizontal wall portion 33 of the partition or wall 26 is likewise provided with apertures 63 correspond- -ing in number and location to the apertures it will be noted that the end Wall 58 and the side walls 60 of the shroud member 58 have formed therein air flow openings 64, thereby rendering the shroud member foraminous.
The shroud member 538 is particularly characterized by the provision thereon of a plurality of resilient bumpers or buttons indicated at 66. The bumpers or buttons 66 conveniently comprise a generally semi-spherical knob portion which preferably projects inwardly for resilient abutting engagement against the end wall 43 which adjoins the end wall 59 of the shroud member 58. A neck portion of reduced diameter sufliciently small to the openings 64-, or a separate opening, if desired, is provided on the bumpers or buttons 66, and there is further provided a fiat retainer portion 67 which overlies the edges of the corresponding opening, thereby locking the bumpers or buttons 66 in place on the end wall 59 of the shroud member 58.
By virtue of such arrangement, simple fastening means such as a metal screw 69 is provided for each set of openings 62 and 63 and the shroud member 58 is drawn into firm assembly with the partition or wall 26, while the motor fan unit is resiliently and firmly clamped between the gasket 50 and the resilient bumpers or buttons 66.
In the embodiment shown, there are three bumpers or buttons 66 and three metal screws 69. Thus, the entire motor mounting assembly requires only three simple metal screws and yet a fully cushioned assembly is provided. p
In order to form a secondary filter for the cleaner, there is provided a generally cup-shaped filter cap 78 which includes an end wall 71 and a cylindrical side wall 72, the filter cap '70 comprising any suitable filtering material such as a porous felt, or the like. The flexible filter cap 70 generally conforms in size and configuration to the shroud member 58 and as shown in Figures 1 and 2, fits over the shroud member 58 in snug relationship therewith.
The upper housing 11 carries a peripheral gasket 73 on the flange 22, which gasket is shaped to provide a circumferentially extending bumper for the machine, as well as a sealing gasket portion 74 which extends between'the flange 22 and the flange 17.
There is further provided on the upper housingll, a pair of toggle clamps 76, 76 which engage the underside of the flange 17 on the lower housing 12 to lock the upper housing 11 in firm sealed-together assembly with the lower housing.
As shown in Figures 4 and taken in conjunction with Figure l, the upper housing 11 has formed in the side wall portions 21 thereof, an inlet opening 80 particularly characterized by an inwardly extending em bossed flange 81. I
Received within the inlet opening 80 is a ferrule 82 which more particularly includes a cylindrical barrel potion 83 struck out as at 84 at one or more circumferentially spaced points to provide an oilset radially outwardly projecting lug or tongue 86.
The ferrule .to the lugs or tongues 86 on 82 further includes a flange 87 which overlies the edges of the opening on the outside of the upper housing 11, but which is retained in spaced relationship with respect thereto by an annular axially extending wall terminating in an edge portion 89 engaging against an adjoining wall surface of the upper housing 11. There is thus formed an annular clearance space 90 between the upper housing 11 and the flange 87.
It will be understood that after the ferrule 82 is inserted into the opening 80, the lugs or tongues 86 are offset behind the embossmcnt 81 on the inside-of the housing 211, while the flange 87 overlies the edges of the opening 88 on the outside of the housing, thereby to place the ferrule 82 in firm assembly with the upper housing 11.
Although other forms of filtering means could be employed, it is contemplated that the present cleaner can advantageously utilize a disposable filter bag made of a porous paper filter material, such a filter bag being indicated generally at 91. The filter bag is characterized by a reinforcement 92 having an inlet opening 93 formed therein. As shown in Figure 6, at selected circumferential points on the opening 93, radially outwardly extending slots 94 are formed corresponding in number and location the ferrule'82. Thus, to attach the filter bag 91 to the inlet opening 80, the reinforcement 92 is merely placed in register with the inlet opening and the lugs or tongues 86 are passed through the slots 94 whereupon the reinforcement and the bag 91 are twisted to effect a bayonet-locking action, the respective lugs 86 underlying the edges of the opening 93 in the reinforcement 92.
As shown on Figures 1, 4 and 5, the flange 87 of the ferrule 82 is particularly characterized by the formation therein of a pair of circumferentially spaced slots 96 and a corresponding pair of circumferentially spaced openings 97, each slot and each opening 96 and 97 constituting a matched pair of slotted openings for cooperative engagement with a latching mechanism of a hose coupling connector provided in accordance with the principles of the present invention.
Thus, as shown in Figures 4 and 5, a fabric hose 98 is provided by means of which the cleaner 10 may be operated with the usual accessories, such as cleaning wands and the like. At the end of the fabric hose 98, there is provided a terminal tube 99. The fabric of the hose 98 ,forms a shoulder 100 along the length of the terminal the bead 101 and-the shoulder 100, there is provided a locking ring 102 having a radially extending wall 103 reversely flanged as at 104.. The axially extending wall of the ring 102 terminates in a forward edge 106 characterized by the formation there-- in of two circumferentially spaced lugs 107 each having: a finger extremity formed thereon.
A coil spring 109 is bottomed at one end against the bead 101 and is bottomed at its opposite end against the radial wall 103, thereby to normally bias the locking ring: against the shoulder 100 provided by the fabric hose 98.
In order to assemble and lock the hose in the inlet open-- ing 80, the terminal tube 99 is inserted inthe inlet open-- ing through the barrel portion the same time, the locking ring 102' is manipulated to pass the respective lugs 107 through the corresponding set of and the terminal tube 99 is withdrawnfrom the ferrule 82.
As shown in Figure 4, when the hose 98 is assembled with t e cleaner, the terminal tube 99 actually extends 83 of the ferrule 82. At
. hancing the portability of the housing and a flange into the filter bag 91 through the reinforcement 92, thereby to discharge dirt-ladenair into the interior of the filter bag. a t r Thefiltered air then passes through the secondary filter 70 and through the opening 64 of the shroud member 58, through the motor fan unit 37, whereupon the air is discharged into the discharge compartment 28 and is diffused through the sound-deadening hat of material 19, and through the outlet openings 18 in the lower housing 16.
As .shown in Figure 2, the lower housing 12 may be provided with embossments 116, each carrying a swivel caster 117 equipped with roller wheels 118, thereby encleaner in the course Ofopbrationthereof. p a a a Although various minor modifications might be sugs ated by those versed inthe, art, it, should be understood that I wish to embody withiiithe scope of the patent warranted hereon, all such modifications as reasonably and properly come within the scope of my contribution to the art. j
