substituted for abandoned application` serial No.
77,657,'May 4, 1936. This application September 17, 1945, Serial No. 616,867 e Thisinvention relates to cleaning devices, Vand more particularly to a vacuum cleanerto .clean such articles as dust mops and dust cloths.V
Dust mop cleaners heretofore invented have been impractical, due', primarily, to insuilicient suction, and secondly to their unwieldiness. `A further disadvantage has beeny their lack `of adaptability, as, for example, when such cleaners' were designed to clean dust 'mops they could not clean dust or polishing cloths satisfactorily. This yinvention is a substitute for the device claimed and `spe ifled`in'myA forfeited and now abandoned application, Serial Number 77,657, filed May 4, 1936. e f n One object of the present invention is to produce a vacuum cleaner for dust mops which will develop suicient suction to clean them effectively.
Another object is to produce a vacuum cleaner which adapts itself readily to various sizes and types of cleaners, such as dust mops, dust cloths, etc.
A further object is to produce a vacuum cleaner for cleaning dust mops, dust cloths, etc., which occupies a minimum floor space. y
Other objects are to produce a vacuum cleaner for dust mops and the like which may be easily stored and cleaned, and which is economical to manufacture and use.
The accompanying drawings illustrate one form of the invention. In the drawings:
Figure ly is a vertical cross-section through the center of the cleaner.
Figure 2 is a cross-section on the line 2-2 of Figure 1, looking in the direction of the arrows; and
Figure 3 is a plan view of the top of the cleaner.
In the drawings, in which like numerals indicate like parts throughout the several views. a motor I is mounted in the bottom of a container II', with the shaft I4 of the motor vertical.
A fan casing I2 is carried on the upper end of the motor and houses a fan I 3 which is connected toand driven by the motor shaft I4. The fan i3 draws air in through an intake opening I5 in the upper side of the fan casing and expells it through an exhaust port I6 and into a dust bag I1 in a manner common to vacuum cleaners with centrifugal blowers.
yA cone 20 is connected to the intake opening I5 at the apex, and diverges upwardly to meet the sides of the container. A second cone 2l s claims. (cl. -310) in Figure 3.
mounted above the cone 20 and of lesser slope di- 55 2 verges upwardly fromthe center and is joined to the cone 20 and to the inner surface ofthe container at the outer edgeof the cones to'form a cleaning chamber 22 in the container above the cones and a suction chamber 23 between the cones. l a
A plurality of ports 24 through the surface of the upper cone .2| form a series of apertures through which the air is drawn at high velocity from the cleaning chamber 22 into the suction chamber 23. The air passes through the suction chamber 23 and into the fan I3 which discharges the dust ladenair'into the dust bag I1.
The dust bag is made to lie horizontal in the container II and partially ksurround the motor I0, as `shown in Figure 2thus giving a compact unit. `The lower part of the container is` provided with a screen door 25 through which the bag may be removed for cleaning. The screen allows air which has been drawn into the dust bag I1 and which has been expelled through the fabric of the dust bag to escape from the bottom of the container.
A cover 26 is provided for the container. The cover 26 is preferably made of fabric which will permit air to enter freely but which will prevent dust' from being forced out of the cleaning chamber 22 by eddies.
The cover may be divided into four sections for convenience, and the sections connected by sliding fasteners 21, commonly known as zippers and shown enlarged in the circle inscribed A dust mop may thus be inserted into the cleaning chamber 22 by opening three or four of the zippers 21, and the zippers closed tightly about the handle of the dust mop before shaking it. By opening only one zipper or two alined zippers dust cloths may be inserted and shaken.
To clean a dust mop, three or four of the zippers 21 are unfastened and the mop inserted in the cleaning chamber 22. The zippers 21 are then fastened about the handle of the mop and the mop shaken and moved about in the chamber. As the mop moves over the various apertures 24 they are subjected to the relatively strong suction due to the restricted area of the apertures and the dirt is effectively removed.
Having thus described the invention, it is realized that it is susceptible to various changes and modifications, and it is not therefore desired to limit it to the precise form herein shown and described, but only by the scope of the appended claims. l
What is claimed as new and desired to secure by Letters Patent is:
1. In a device of the character described comprising a casing, a cleaning chamber in the upper portion of said casing, a conical bottom to said chamber sloping inwardly and downwardly, and having a plurality of apertures therethrough,
v a secondinwardly andv more sharply downwardly sloping `conemounted below and iixed tothe iirst cone at the peripheries of said cones to form a suction chamber therebetween, a suction fan connected to said suction chamber and a dust bag, said fan causing the air from said ch-amber to be forced into said dust bag. l Y
2. In a device of the character described, a
casing, a cleaning chamber Iin theupperporton of said casing, an inwardly and downwardly sieping cone attached to said casing andl forming the bottom of the cleaning chamber, said cone having a plurality of perfcrations `therethrough at Iizlifierent elevations thereon, an auxiliary cone be low said cleaning chamber, Asaid auxiliarycone provided .with an opening at its extreme lower end, a motor inthe lower part of said casingbe- -low said auxiliary cone, a fan driven by said. motor and adapted to draw air and dust through said opening at the extreme lowerend of said auxiliary cone and exhaust the same, and a dust `bag within said casing, said dust bagv in communication with the exhaustof said fan to receive air .d
.ing cone attached to said casing and formingihe bottclmof said cleaningv chambensaid cone hav- 4 diierent elevations thereon, a second cone xed to said casing and below said rst cone and converging downwardly to form a suction chamber between said cones, a fan in communication with said suction chamber to draw air and dust from said cleaning chamber through the perforations and the suction chamber, a dust bag receiving `air and dustdischarged fromsaid fan, and an ,electric motor to drive said fan, said dust bag,
