May 31, 1932. T. E. D. BILDE VACUUM CLEANER Filed Jan. 7, 1930 Patented May 31, 1932 UNITED STATES PATENT OFFICE TORD ERIK DANIEL BILDE, OF STOCKHOLM, flwEDEN', ASSIGNOR, BY MERE ASSIGN- MENTS, '1'0 ELECTROLUX CORPORATION, A CORPORATION OF DELAWARE vacuum CLEANER Application filed January 7, 1980, Serial No.
My invention relates to the vacuum cleaner art and more particularly to electrically operated vacuum cleaners of the. domestic ty e. g
y major object of the invention'consists in the provision of rods orthe like, preferably metallic. and resilient, arranged between the motor-fan aggre ate and the casing of the cleaner and axial y with respect to the motor to form a resilient and sound deadening support for said aggregate v A still further object of my invention is to provide a vacuum cleaner in which the motor-fan aggregate is supported resiliently and is electrically insulated from the casing of the cleaner.
Further objects and the nature and advantages of my invention willbecome apparent from consideration ofthe following descrip tion taken in conjunction with the accofnpanying drawings showing three embodiments of the invention.
In the accompanying drawings Fig. 1 is an elevational view, chiefly ,in section, I of the 2| rear end of a vacuum cleaner according to the invention, Fig. 2 is a cross section along the line 2-2 of Fig. 1, and Figs. 3 and 4 are two'modifications of the supporting arrangement for the motor-fan aggregate. 80
,nates a cylindrical casing, which is supported bya runner arrangement 11 so that, when the supporting surface, is horizontal, the axis of the casing is horizontal. A' removable cap -12 forms the right end (Fig. 1) of the cleaner.
In the pressure chamber, a fan 14 and the driving motor 15 for the fan are arranged. At the front and rear ends of the housing of motor 15, projections or lugs 16 are provided, which may be cast in one piece with said housing. Rods or ;,the like 17 are fixed b to lugs 16, said rods .or the like being advan- 'tageously manufactured of spring steel. They may be so made as to provide an electrically non-conducting path. If the rods or springs are manufactured of metal, they may be provided witha layer or coating of electrically insulating material. Rods 17 are di- In the figures, reference character 10 desig- A partition 13 divides casing 10 into a pressure chamber and a vacuum chamber.-
mensioned in such manner that the same have a certain resiliency in relation to the motor fan aggregate. In casing 10, aring 18 advantageously manufactured of electrically insulating material such as rubber, hard rubber or like composition is secured by means of screws 19 or the like. Ring 18 is provided with a number of supporting members or lugs 20 extending into the casin which are axiall apertured to receive the ro s. In the embodlment shown in Figs. 1 and 2 there are three such members 20. Rods 17, as is evident from the drawings, pass through the members 20, which serve as supports for said rods. Projections 16 are placed in such manner on the housing of motor 15 that the transverse vertical plane through the center of gravity and the middle points of rods 17 intersect. The motor-fan aggregate is supported by members 20 at or near these points. Set screws 21 prevent axial movement of the motor-fan aggregate relative to casing 101 If the rods 17 are manufactured of metal and not provided with any electrically insulating coating, plugs 22 of electrically insulating material are pro- 15 vided to cover the screws.
From the above it will be evident that the motor-fan aggregate is resiliently supported within casing 10 and by means of rods that the motor-fan aggregate is electrically insulated from all parts of the cleaner which may be touched by the operator during operation.
In the embodiment shown in Fig. 3, rods 17 are provided with apertured members 23 extending between projections 16 and members 20, and adapted to limit the axial movement of the motor-fan aggregate in relation to casing 10, should screws 21, for any reason have become loose. In this construction,
preferably manufactured of any resilient and electr 'ically insulatingmaterial such as rubf Fig. 4 shows a further embodiment, in. which the housing of motor 15 is provided with projections .16 at oneend only, so that the'elastic rods 17 are connected with said housing at one end only, i. e. the rods are connected at one end to projections 16 whereas the other end is supported by members 20 in the same manner as shown in Figs. 1, 2 and 3.
The rods or the like 17 may in a modified embodiment be secured to ring 18 and the housing of motor 15 may be provided with members corresponding to members 20.
