11 Claims.

This invention relates to vacuum cleaners and has as its general object to provide a hose retainer formed as a unitary part of the suction producing, air filtering and dust collecting unit, or cleaner body.

A more specific object of the invention is to provide a vacuum cleaner having a hose retainer encircling and spaced from a portion of the cleaner body so as to retain in position a hose coiled about said body portion.

Another object of the invention is to provide a vacuum cleaner having a hose retainer having the additional function of supporting or assisting in supporting the cleaner body in a horizontal position.

Other and further objects will appear to those skilled in the arts to which this invention appertains as the description proceeds which taken in connection with the accompanying drawings sets forth a preferred embodiment thereof but it is to be distinctly understood that any and all modifications, alterations and variations of structure coming with the spirit and scope thereof are to be included herein; The invention is to be limited onlyby the definition set forth in the appended claims.

In the drawings.

- to connect the floor tool with the cleaner body.

In' ordinary practice the manipulation of the hose and its storage when not in use constitutes an annoying problem for the user of the machine. It is difficult to hang up the hose in a closet,

and it gets in the a. when laid on the closet fiopr as contrasted with the wand which can beset in a corner and-leaned against the wall. It frequently happens when the cleaner is carried about the house that the user finds it difiicult to carry both hose, wand and cleaner all at the same time. My invention permits the hose to be carried as a unitary part of the cleaner body assembly, thus eliminating these difficulties. The

hose is supported about the cleaner body by means of a retainer which is substantial enough to function as a handle with which tocarry the cleaner body about. I

Cleaners of the above type require a judicious placing of the several parts and one of these is .the air outlet when it is intended to use the its side.- The hose retainer cooperates with the cleaner. body in supporting the latter'in a substantially horizontal position thus permitting the use of the blower attachments and preventing the cleaner body from rolling around over the floor as it is being used.

The cleaner body comprises a motor and suction housing I, mounting a filter housing 2 on which a cover unit 3 is appropriately supported. The entire structure is mounted on a base 4 which rests upon the floor, for supporting the cleaner body in a vertical position; A filter unit 5 is arranged within the filter housing 2. The cover 3 and filter 5 and associated structure is preferably constructed in accordance with the disclosure set forth in application S. N. 337,836 filed May 29, 1940.

The filter and motor housings 2 and I are joined by an annular band 6 to which each of the housings I and 2 is appropriately secured in any well known manner. The band 6 has a plurality of uniformly spaced lugs I integral therewith. I provide a combination hose retainer, handle and supporting means including a ring 8 encircling the filter housing 2 near the upper end thereof, and open work in the form of rods 9 connecting the ring 8 to the band 6 and thereby the housings 2 and I. Open work is employed in order to reduce weight as much as possible. Preferable, the open work is in the form of rigid rods 9 extending longitudinally of the filter housing 2, one end of each rod being se- 7 cured in a lug I and the ring 8 being securely atas to provide a basket-like retainer for the suction hose III which is adapted to be coiled about the filter housing 2. The hose may be easily withdrawn andinserted between the cover 3 and ring 8.

There has thus been provided a convenient same character as the corresponding parts in Figs. 1 and 2.

The cleanenbody in this instance is surrounded by a frame work comprising a series of rods l5 preferably six or eight in number but shown in the instant illustration as six in-number. These rods extend from'the base II to a ring l6 near the upper end of the filter housing II. The ring It may be of a comparatively thin section. The rods I5 may be secured to base H and ring IS in any appropriate manner and are very rigidly secured thereto.

The intermediate regions of the rods I5 are supported by rests or supports integral with a ring l8 to which the housings I2 and I3 are secured. Each of the supports or rests H has a notch therein in which a rod I5 rests. Each rod therefore is maintained perfectly rigid.

The rods l5 form shoes or runners for supporting the cleaner body in a horizontal position, as shown by ground lines I9 and in Figs. 6 and '7. The object of placing the cleaner in a horizontal position is to enable its use as a blower. In Fig. 7 the base of the machine is shown as incorporating a removable plate 2| secured to the base II by means of a plurality of screws 22, or any other appropriate securing means. The plate 2| is provided with an opening 23a to which hose 23 may be secured. The cleaner body may, if so desired by the operator, be continually used in a horizontal position, the rods or runners I5 providing adequate support for the cleaner at all times in such horizontal position.

It will be observed that the space between rods I5 and filter housing I3 constitutes the space for storing the cleaner hose 23. The method of inserting and removing the hose is identical to that of Figs. 1 and 2. The rod supports I'I also provide a means for keeping the hose in the space provided. The ring I6 may also be employed as a handle to transport the cleaner about.

The,-structure shown in Figs. 8 and 9 likewise discloses a base 24, a suction unit housing 25, a filter housing 26, a filter 21 and a cover 28. The

, base 24 in this disclosure is hexagonal in shape although any other number of sides may be employd. The hose retainer comprises a plurality of rods 29, arranged about the filter housing and extending between a band 30 connecting filter housing 26 and suction unit housing 25, and "a ring 3| disposed near the top of housing 26. The rods are preferably curved at their ends as shown and firmly secured to the band 30 and ring 3| by any well known means. Band 30 is preferably provided with a plurality of bosses 32 into which rods 29 are fitted.

When using the cleaner as a blower, it is essential that the cleaner be laid on its side to disclose the outlet 33. To maintain the cleaner in any one of a plurality of horizontal positions rods 29 and only one of the faces of base 24provide the supporting means. Ground line 34 indicates that the corners of the base 24 and rods 29 lie in exactly the same plane. An examination of Fig. 9 shows that adjacent rods and the faces of base 24 lie in a common plane. It is therefore evident that the cleaner has the full equivalent of a plane surface on which to rest when in a horizontal position.

The rods 29, ring 3|, and the band 30 to which said rods are secured at their lower ends form a supporting element for keeping the suction hose wound about the filter housing, in the same manner as described in connection with Fig. 1. Ring 3| is built in such proportions as to enable the operator to use it as a handle.

The modification shown in Figs. 10 and 11 includes a base 35. a suction unit housing 36, a filter housing 31 ,and a cover 38,'the base 35 being hexagonal in shape as illustrated although any other shape may be employed. A filter 39 is disposed within the filter housing 31 as shown.

The hose retainer comprises a plurality of rods 40 rigidly secured to bosses 41 on a band 4| to which housings 36 and 31 are connected, and to a ring 42 encircling the upper end of filter housing 31.

The cleaner body of this form of the invention is supported horizontally, in order to permit access to the outlet 43, by the ring 42 and any one of the hexagonal faces of the base, providing substantially a thre point support on the surface 44. The rods 40 do not in reality function as runners as ,they do in Figs. 5 and 8. The cleaner will lie in a substantially horizontal position and by reason of the disposition of the ring and'base will avoid the tendency to roll or tip on its side. The rods act only as a support for the ring 42 and therefore only indirectly support the cleaner.

The rods 40 provide a convenient means for keeping a suction hose 46 wound around the filter housing in the manner set forth in connection with Fig. 1. The ring 42 may be employed as a handle as fully explained in the previous illustrations, to transport or carry the cleaner about. Various configurations of the bases of the cleaner may be employed to permit the escape of the air from the cleaner when used in a vertical position. For example, portions of said bases may be hollowed as indicated by the dotted lines to provide convenient apertures. This feature however is not material to the instant invention and the exact expedient employed is deemed within theskill of the designer and the apertures shown by the dotted lines is only suggestive.

The rings 8, I6, 3|, 42 need not be'exactly circular, and the term ring as employed herein,

is intended to cover not only circular rings but rings of approximately circular or polygonal shape.

The disclosure set forth in Figs. 1 and 2 may also be used in a horizontal position. If this is desired it is preferred that the rods 9 be increased in number similar to that in the other figures and that preferably the base I, be increased in size or diameter such as set forth in connection'with circling and spaced from said filter housing to define a hose receiving annular passage, a plurality of rods spaced from each other and from the housing means, each secured at one end to said housing connecting means and at its other end to said ring, said rods functioning to retain a hose coiled about said filter housing, and said ring being arranged to function as a handle.
