7 Claims.

My present invention relates to vacuum clean ers and is in the nature of a modification of or improvement on the vacuum cleaner with auxiliary mop cleaning attachment disclosed and claimed in my prior Patent No. 2,219,911 of date October 29, 1940.

In the present improved device the mop receptacle is in the nature of an open pan or pocket formed as a part oi the dust-receiving bag and having connections whereby,under proper adjustment of valve mechanism, the dust or lint from the mop will be drawn from the mop receptacle through the fan or into the dust bag. Under other proper adjustments of the valve mechanism, the vacuum cleaner may be used in various different ways, for example, to pick up dust or lint from the-floor and blower and delivered' Q is a rotary cup-shaped valve-l1 that is provided with an axial shaft or stem I! that extends to the exterior of the head of the pick-up nozzle and, in the preferred construction illustrated, is

provided with a rigidly secured arm I9. The

open end of this rotary cup-shaped valve ll registers with the eye l5 of the fan casing ii. The rotary or oscillatory valve I1 is provided with a single deliver the same into the bag in the customary way.

An improved and commercial form of the present invention is illustrated in the accompanying drawings, wherein like characters indicate like parts throughout the several views.

Referring to the drawings: Fig. 1 is a view in perspective showing the complete device;

Fig. 2 is a fragmentary view in front elevation with some parts broken away and with some parts sectioned on the line 2--2 of Fig. 4;

Fig. 3 is a fragmentary front elevation of the valve-actuating device;

Fig. 4 is a side elevation of the complete device, some 'parts being broken away and some parts being sectioned; and v Fig. 5 is a vertical section taken approximately on the line 5-5 of Fig. 1.

My'invention is capable of being incorporated in connection different designs but, as shown, is applied to a vacuum cleaner in which the'head or body of the cleaner involves a motor casing ID, a fan casing II, and a pick-up nozzle 12, said device being adapted to ride upon wheel-equipped arms 13 shown as attached to the motor casing ill. Preferably, the elements l0,.ll and 12 will be separately made but rigidly connected.

Working within the fan casing II is a fan ll secured on a shaft l5 journaled in the front wall of the motor casing l0 and connected to and driven by the motor, not shown, but which, in the type of vacuum cleaner illustrated, is located in the motor casing it. The fan casing II, has an axial air intake passage it.

Mounted in the head of the pick-up nozzle 12 device showing especially the pick-up nozzle and with vacuum cleaners of various axial air intake port 20, see particularly Figs. 2 and 5, that normally registers with a port 21 in that portion of the head of the-pick-up nozzle that constltutes'aseat for the valve ii. That portion of the head of the pick-up nozzle that constitutes a seat for the valve I! has a tubular extension 22 that is normally closed by the valve but is adapted to be opened when the valve is rotated about or far enough to bring the valve port 20 into registration with said tubular extension 22 and at the same time to close the port. that leads from the nozzle to the interior of the valve. l

The main receptacle or dust has proper; indicated at 23, is of the usual flexible material .that is impervious to the passage or dust, but

will permit the escape of air as is customary in a vacuum cleaners.

The fan casing I I has a tangential or peripheral discharge neck or nozzle 24 to which the bag 23- is adapted to be connected by a coupling 25, preferably such as usually.employed, In its upper or extended end-the bag}! is formed with a mop receptacle preferably a dish-like structure or depression formed by a dished. diaphragm 26 which, at its contracted bottom, is provided with an inset quite coarse mesh wire screen 21. The

diaphragm'28 is preferably of quite stiff rubber but should be of some material that is impervious to the passage of air. so that under air pressure from within the bag there will be no escape of air through said diaphragm.

Within the bag 23 is a suction pipe 28, pref erably a rubber tube, having a flaring receiving end 29 that is vulcanized -or otherwise rigidly secured to the diaphragm just radially outward of the screen 21. At its delivery end the tube 28 is extended to the exterior of the bag 23 and by a coupling 30 is connected to the receiving end of the tubular extension 22. shown is provided with the customry handle bar 3|, the forked end 32 of which is pivotally connected to the head or body portion of the vacuum cleaner, the said prongs, as shown, being pivotally connected to the

tubular extensions

22 and 24. The upper end of the bag 23 is conveniently with and is in constant communication The vacuum cleaner hung from the upper end of the handle bar 3| by suitable means such as a hanger strap 33.

In this preferred arrangement, the oscillatory valve I1 is, as already indicated, normally'held in the position shown in Figs. 2 and 5; and this is shown as accomplished by torsion spring 34 anchored to the head of the intake nozzle and to the valve stem Is. Said valve stem II, at its extended end, is provided with a short arm or lever 35 provided on its hub with a lock lug or shoulder 36 which, when said lever is depressed,

will be engaged bya spring-pressed latch dog 31 pivoted at 38 to nozzle.

When lever 35 is depressed and held by latch dog 31, valve I! will be moved so as to close the port 2| of the intake nozzle and open comthe head of the pick-up munication between valve port 20 and the tubular extension 22, thereby connecting the suction pipe 28 to the fan. Of course, the open end of valve i! will always be in communication with the eye,

it of the fan casing ll.

An ordinary dust mop is in Fig. 4 and is indicated by the character A. When the intake of the tan is connected to'the suction tube 28 and a mop is placed in the mop receptacle 26, and especially when the mop is rubbed or moved over thereof may be made within the scope of the invention herein disclosed and claimed.

.What I claim is:

1. In a vacuum cleaner, a fan casing and a rotary fan therein, a pick-up nozzle having a delivery conduit leading to the intake of said fan casing, a dust-collecting bag connected to the outlet of said fan casing, a mop receptacle formed as a part of the outer wall or said bag and exposed at the exterior thereof for the insertion of a mop, a dust delivery conduit leading from said mop receptacle to the intake of said fan casing,

' and valve mechanism constructed and arranged,

the screen 21, not only dust but the lint from the mop will be drawn into the suction tube and from thence will be carried to the motor-driven fan and from thence blown into the bag 23. To briefly summarize the. above operation when valve I1 is in so-called normal position indicated in Fig. 2, dust will be picked up from the pick-up nozzle and delivered into the fan and when said valve is moved to the position just above noted and latched in that position by the dog 31, dust will'be drawn from the mop receptacle and the mop and delivered into the bag. When the valve has been latched in the position last noted and is desiredtoreturn the valve to its normal position, it is only necessary to press upon the latch dog and thereby permit the torsion spring 34 to quickly restore the valve to its normal position first noted. a

set, v

In Fig. 4, the bag It is shown as provided with a.

clean-out opening normally closed by a plate or closure ll.

It is important to note that in this present embodiment of my invention, a single valve serves to form all 01' the valve opening and closing movements necessary to convert the machine from one that picks up dust or dirt from its pick-up nozzle or from the mop receptacle. Also this is accomplished by a valve of novel construction, the interior of which is always o'pen to the source of partial vacuum, to wit: the motor-driven fan or blower. i

In the device of this application the mop receptacle 28 forms a part, to wit: as shown, the

upper end of the dust bag and the concave or.
