Description

corporation ot Germany Application November 24, 1934, Serial No. 754,583
In vGermany November 25, 1933 1 claim. (ci. 1515s) UNITED STATES PATENT f OFFICE My invention relates to a vacuum cleaning de vice and more particularly to a rotary brush for floor polishing, cleaning and the like of the type disclosed in myU. S. Patent No. 1,984,191, dated December 11, 1934, and of which the present application is a division with respect to Figs. 4 and 5 originally disclosed in the application for said patent. y
l Suctionl cleaner nozzles in which 'a rotatably mounted annular brush is rotated by .a vacuumoperated blade wheel are well known. In such nozzles the blade wheel and the brush are separately secured to the shaft carrying the same, the blade wheel being arranged in a particular casing. Furthermore, special air channels are disposed in the walls of the nozzle which direct the current of air through the blade wheel. In such an arrangement a considerable loss of power is. caused due to the fact that the air must follow a tortuous path on passing through the suction nozzle so that the residual power hardly suffices to` drive the blade wheel. Besides, the dust easily adheres to the surfaces of the numerous corners in the channels and 'may cause a clogging of the latter.
'I'he object ofmy invention is to provide an economical vacuum-operated floor polishing brush so simple and compact in design as to ensure a reliable operation thereof and whereby the y 'suction effect of the cleaner is substantially utilized to the full extent for an effective polishing of floors. f
According to the present invention the bristles of the brush in contradistinctionto vthe hitherto employed rotary brushes are immediately secured to the lower blade edges of the blade wheel. By omitting the wall between the brush and the blade Wheel on which the air impinges in theaxial direction the great advantage is obtained in thatthe suction air may freely flow through thesuc-- tion nozzle. in a substantially straight path. In such a device the greatest portion of power of the air drawn in is utilized -to rotate the brush secured to the blade wheel. l@uch a rot'ary brush may be, consequently, also employed for vacuum cleaners having a small suction effect.
Figs. 1 and 2 ofthe accompanying drawing illustrate an embodiment of my invention inA a diagrammatic form.
Referring to Figs. 1 and 2, l denotes the casing in the shape of an inverted cup forming a vacuum cleaner nozzle having a neck 2 for fastening a exible tube. In the central portion of the casing I a shaft 4 is rotatably mounted on atransverse support 3, theblade wheel lbeing iirmly secured to the shaft 4? The rotation of the blade wheel is caused by the current of air passing through the nozzle in the direction of the arrow 1. Rows 6 of brush bristles are arranged on the lower edges of the blades 5 to form radiating' series, the bristles extending parallel to the shaft 4. 'By the rapid rotation of the blade wheel 5 the brush is causedto rotate, so that the surface to be' treated is polished in a most effective manner. The whirl of dust caused by-the rotation of the brush -is drawn through the neck 2 into the dust container of the vacuum cleaner. This device `has, consequently, the advantage of being very eiilcient, economical-and simple in construction,
Alight in weight and easy to manipulate. Further,
in such a device an electric motor with a particular lead is dispensed with.
I claim as my invention:
A floor finishing device, comprising an inverted cup-shaped casing, a tubular extension on said casing adapted to beconnected to a suction device, a transverse support in said casing, a fan blade wheel closing the lower portion loi! said casing and being jpurnalled in said support and having vradially extending rows of brush bristles, each row beingyflxed to the lower edge of one ofthe fan blades, to form a bushwith bristles arranged in radiating series and rotated by the blade wheel when the latter rotates Adue to the air drawn byA lthe suction device through the casing.
