- a convenient carrying handle l'l extends along the top side of casing II.
- the other end of casing H is closed by a removable end cap is the upper portion of which is provided with a second hose coupling l8 which normally serves as the exhaust air outlet and to which the flexible hose may be coupled when it is desired to use the cleaner as a; blower.
- the power unit comprises an electric driving motor 20 to the forward end of which is coupled a multiple stage fan unit 2
- the circular outer casing of the fan has flanged ends and forms a cord storage reel for the cleaner service cord 23' as will become more clearly apparent hereinbelow.
- the motor 20 is of a well known design having a rotating armature and a surrounding field structure over which the air exhausted by fan 2! passes on its way to the exhaust air opening IS.
- a generally tubular assembly 24 comprising several tubule-r stampings and fittings, as clear- 1y shown in the drawings, forms an axial extension of the motor ran unit 217, 21.
- End cap Not this assembly together with the circular fan inlet housing 22 constitute journals for the opposite ends oi the motor-ran assembly. These journals are respectively: supported in bearings as, it in buikheacs 2c, 29.
- Bulkhead 28 is apertures at, $0 to permit th haust air to move therethrough and its outer perimeter is secured to the cleaner casing II as by screws 3
- Bulkhead 29, on the other hand. is imperforate, except for an opening registering with inlet 22, and is secured to the casing by spot welding or otherwise.
- spider 32 Inwardly of bulkhead 28 and parallel thereto is a spider 32 having an opening at its center through which a small diameter thimble 33 of assembly 24 extends. Spider 32 cooperates with bulkhead 28 to support a frusto-conical final filter element 34.
- the innermost end 35 of a flat, steel, spirally arranged spring 36 is secured to spider 32 adjacent thimble 33.
- the outer end 31 of spring 36 is secured to a disk 38 rigidly attached to assembly 24.
- Spring 36 is arranged to urge the motor-fan unit to rotate counterclockwise as viewed in Figure 2.
- spring 36 always tends to reel the service cord 23 inwardly upon the storage drum pro vided on the exterior of suction fan 2
- the motor casing may be utilized as the cord reel in lieu of the fan casing. if desired, and more particularly in applications to portable appliances having only a motor.
- the control mechanism for locking the motorfan unit against rotation during operation of the cleaner and at all times except during reeling or unreeling of the service cord is shown as mounted about forward bearing 21 of the motor-fan unit.
- This control is entirely housed within the cleaner casing in the space between bulkhead 29 and the adjacent end of fan 2
- the control comprises essentially a clutch which may be selectively clutched and de-clutched by means of a pivoted pawl.
- the control comprises a collar 39 which surrounds bearing 21 and is rigidly secured to bulkhead 29.
- a toothed disk 40 is welded or otherwise secured to collar 39.
- having a specially contoured periphery is journaled loosely upon collar 39 and is normally held in firm frictional engagement with the adjacent face or disk 40 by means of a light disk spring 42 rigidly secured to collar 39.
- One rim 43 of the combined fan casing and service cord reel carries a pivoted pawl 44 biased toward the edges of disks 46 and 4
- the innermost end 46 of service cord 23 is secured to motor at 41.
- the lead wires of the service cord are connected directly to the motor through a push-push type switch 48 mounted on end cap of assembly 24.
- the control button 49 of switch 48 projects outwardly through an opening in end cap l3.
- Switch 46 is of the type which is opened upon depressing button 49 and closed upon the next succeeding depression thereof.
- Control button 49 for the switch is in axial alignment with the motor-fan unit and rotates therewith when the cord is being reeled or unreeled.
- has two notches 5
- is separated into two pairs of segments one pair 52 of which has a radial extent somewhat less than that of teeth 50 while the other pair of segments 53 has a radial extent somewhat greater than the radius of teeth 50.
- the several segments are interconnected by cam surfaces shaped to facilitate the passage of the pivoted pawl or detent 44 thereover.
- pawl 44 may be said to operate to declutch these two disks which are normally held clutched together in a, stationary position by light spring 42.
- the fan draws air inwardly through the usual hose connected to opening I5, through the walls of filter l6 and into fan inlet 22. Air exhausted from the rear of the fan passes over the motor to cool it, through an opening not shown, after which it passes through final filter 34 and through opening 30 to exhaust outlet Hi.
