Patented July 6, 1954 CONVERSION ARRANGEMENT FOR SUCTION CLEANERS Edwin J. Ballufl, Livonia Township, Wayne County, Mich, assignor, by mesne assignments, to Henney Motor Company, Inc., New York, N. Y., a corporation of New York Application September 14, 1948, Serial No. 49,219

This invention relates to suction cleaners, and particularly to new and useful improvements therein whereby a suction cleaner may be converted for off-the-fioor cleaning operations.

A principal object of the invention is to provide in a suction cleaner a new and improved arrangement for converting the cleaner for olf-the-floor cleaning operations.

Other and further objects of the invention will be apparent by reference to the accompanying drawings of which there are two sheets, which, by way of illustration, show preferred embodiments and the principles thereof and what I now consider to be the best mode in which I have contemplated applying these principles. Other embodiments of the invention embodying the same or equivalent principles may be used and structural changes may be made as desired by those skilled in the art without departing from the present invention and the purview of the appended claims.

In the drawings:

Fig. 1 is a fragmentary bottom plan view of a cleaner embodying the invention;

Fig. 2 is a fragmentary sectional View on a reduced scale of a cleaner embodying the invention as used in normal cleaning operations, and taken generally along the line 5 of Fig. 1;

Fig. 3 is an enlarged fragmentary sectional view taken along line 3-3 of Fig. 1;

Fig. 4 is an enlarged fragmentary sectional view taken along line 44 of Fig. 1, with the converter only partially inserted;

Fig. 5 is a fragmentary sectional view of a cleaner embodying the invention arranged for off-the-floor cleaning operations, taken along driving means indicated generally at 20, an endless elastic belt 22, and an agitator 24 operatively associated with nozzle I6. The nozzle l6 has a' downwardly presented mouth 26 arranged to pass over a surface covering to be cleaned.

The interior of the nozzle I6 is connected by an air passageway 28 to a fan air. inlet 30, and in normal cleaning operations belt 22 runs on a 11 Claims. (Cl. 15-332) pulley 32 of the agitator 24 and on a pulley 34 of 'the belt driving means 26, so that operation of the fan by the motor will also drive the agitator 24. The operation of the fan induces a flow of air into the nozzle l6 through the mouth 26 thereof. Such air is conducted through the air passageway 28 and the fan air inlet 38 into the fan which pumps such air into and filtering bag 36.

The nozzle mouth 26 and the air passageway 28 are formed by removable plates 38 and 40. A laterally opening port 42 in the side wall of the air passageway. 28 is adapted to receive a converter 44, the cross section of which is shaped to fit the port 42. The port 42 is normally closed by an inwardly opening spring operated closure 45, pivotally mounted in port 42. In its closed position, the closure 45 acts to seal off the air passageway 28 from the outside of the cleaner.

The pulley 34, which, as shown, is formed on a continuation of the motor and fan shaft and is driven by the electric motor, as is the fan l8. An extension 46 of the pulley 34 forms a shaft on which an idler 48 is journaled by means of a sleeve bearing 50. Extension 46 freely turns through sleeve bearing 50. A washer 52 retains the sleeve bearing 56 and the idler 48 and is held in place by a snap ring 54. A flange 56 limits the downward displacement of the belt 22.

The inserted end 56 of the converter 44 is shaped to fit and seat in the air passageway 28 to prevent the fiow of air from the nozzle l6 to fan air inlet 30 and is then in air flow relation with the fan air inlet 30 through opening 58 in the converter 44. Converter 44 is cut away at 59 to accommodate the pulley 34 and idler 48, as shown in Fig. 6 and Fig. 7. During insertion of the converter 44, a slanting face 68 of the inserted end 56 of the converter engages the belt 22 as the converter is moved to its seat in the air passageway, and thereby the belt 22 moves down along the face 66 until it is held between a notch 62 of the converter 44 and a portion of the cover plate 40, this action shifting belt 22 onto idler 48. A part 64 of the air passageway 28 is shaped to fit the slanting wall of the converter and thereby effectively seals off the nozzle I6 from the fan air inlet 30, as shown in Fig. 3. When the belt 22 is thus forced on to the idler 48, the driving connection between the agitator 24 and the fan I8 is broken.

The casing ID has an opening through which converter 44 may be inserted. A spring finger or latch 66 on the converter is provided with a notch 68, engageable with casing lll to secure the dirt collecting converter 44 in the port 42. When spring finger 56 is pressed inwardly, the notch 68 passes through the opening Ill and the converter may be removed. The exterior end T2 of the converter may be connected to a suitable flexible hose to which may be attached the customary suction cleaning tools. The belt 22 is elastic and will be stretched by the insertion of the converter. Upon removal of the converter, the belt 22 will return to ts original position in driven relation with pulley 34, thus re-establishing the driving connection between fan is and agitator 25.

In the embodiment illustrated in Fig. 8, clutch means are used to disrupt the driving relation between the fan l8 and the agitator 24. A motordriven shaft '14 extends into the air passageway 28. An extension 16 of the fan is rigidly secured to shaft M by a nut I8. Extension It has annular clutch face 80. A pulley member 82 is rotatably mounted on shaft '14 and has a clutch face 84 on its upper end operable with clutch face 86. A spring 86 backed by a nut 88 retains pulley member 52 and normally holds the clutch faces 80 and 84 in engagement, thereby causing the pulley 82 to turn with the fan 18 and drive the agitator 24.

When the converter 44 is inserted into port 42, the wall 60 of the converter acts upon the belt 22, which is retained in a groove 9% of pulley member 82, to compress the spring 86, thereby disengaging clutch faces 80 and 84. Fan 48 will now be free to turn independently of the pulley 82, andthe driving connection between fan !8 and agitator 26 will be broken. When the converter is removed, spring 86 urges the clutch face 84 of the pulley 82 back into engagement with the clutch face 88. As the clutch faces re-engage, pulley 82 will again be driven by fan 18, re-establishing the driving relation between fan i8 and agitator 24.
