Application October 22, 1952, Serial No. 316,187

3 Claims. (Cl. 15-257) The present invention relates broadly to vacuum cleaners of the tank type and more specifically to an attachment or tool holder therefor.

Vacuum cleaners of the tank type generally consist of a rigid and substantially cylindrical casing enclosing a motor and dust bag or receptacle. Vacuum cleaners .of this type are usually of one of two designs,namely,

the horizontal tank type and the vertical tank type.

In tank type vacuum cleaners, as well as the conventional upright vacuum cleaner, there is usually provided a large number of interchangeable attachments or tools L for use with the cleaner to enable an efiicient cleaning operation to be performed. The relatively large number of tools and their varied size and configuration has constantly presented a problem as regards their storage and also their accessibility for use with the cleaner during a cleaning operation.

Numerous attempts have been made heretofore to devise an attachment or tool holder for tank type vacuum cleaners. In the majority of instances such designs have been either extremely large and cumbersome or of such a configuration that the vacuum cleaner could not be emptied Without removing all of the tools from the holder. One of the objects of the present invention is to provide a tank type vacuum cleaner having an attachment or tool holder for holding the tools thereon while the cleaner is in operation as well as in storage.

Another object is to provide a tank type vacuum cleaner having an attachment holder embodying a cord guide for maintaining the portion of the electrical cord adjacent the cleaner in a flexible upright position and 4 which cord .guide terminates in a hook member for the storage of the electrical cord.

Another object is to provide a tank type vacuum cleaner having a tool holder formed with a plurality of spaced projections over which the tools or attachments are fitted for securely retaining the tools on the .vacuum cleaner.

A further object is to provide a tank type vacuum cleaner having a tool holder removably attached thereto and configured for securely retaining the tools thereon during operation of the cleaner or during storage or while the cleaner is being emptied.

Still further objects are to provide a tank type vacuum cleaner having an attachment or tool holder removably attached thereto which is readily accessible to the :operator at all times, compact in design and economical 2,713,596 Patented July 26, 1955 vention mounted thereon and showing in dotted lines some of the tools or attachments;

Figure 7 is a side elevational view of a portion of a tool holder wherein the base and projections of the tool holder are made from a single piece of material.

Referring to the drawings where in Figure 1 there is shown a vacuum cleaner of the vertical tank type comprising a cylindrical outer casing consisting of a lower or bottom portion 10 and an upper or cover portion 11. The lower or bottom portion of the casing is provided with a suction inlet 12 to which a hose, not shown, is adapted to be detacha'bly connected in any suitable manner. The upper or cover portion 11 of the casing is supported or mounted upon the upper edge of the lower portion 10 of the casing and is retained thereon by suitable clamps, not shown. The upper or cover portion 11 of the casing is formed with an annular .ofiset upwardly projecting portion 14 of a diameter less than the diameter of the cover 11 and defines with the cover 11 an annular ledge 15. The projecting portion 14, ledge 15 and cover portion 11 are formed as a unit which is clamped to the lower portion 10 to form the outer cylindrical casing of the vacuum cleaner. The outer casing of the vacuum cleaner encloses a customary electric motor .and suction fan and may also contain a dirt retaining bag. In lieu of a dirt retaining bag the lower portion 10 of the casing may serve as a receptacle for collecting and retaining the dirt.

The outer edge of the upwardly projecting portion 14 of the outer casing is provided with a'pluralityof spaced apertures 16 for the discharge of air after it passes through the filter bag. A suitable handle .18 is pivotally mounted upon the projecting portion 14 for lifting and carrying the vacuum cleaner and also for :removing the upper portion .11 of the casing from :the lower portion 10. The top .surface of the upwardly projecting portion 14 is formed with .a suitable opening having a cover plate 19 which is readily detached therefrom :to permit a hose, not shown, to be mounted in the opening so that the machine may operate as a blower. A switch 20 of :any suitable type for controlling the electric motor is mounted on the ledge 15 of the upper portion 11 of the casing. The lower or bottom portion 10 of the casing may be provided with suitable casters or runners, nots'hown, for supporting the cleaner :as it is drawn over the 'floor.

The attachment or tool holder .ofthe present invention, Figure .2, comprises a base portion or member -22 in the form of an endless band which ispreferably formed from a single piece of material, such as 'wire. One end portion of the base member .22 is twisted into an upwardly pro jecting spiral member 23 which terminates in an outwardly extending hook portion 24. The base member 22 at the bottom of the upwardly extending spiral member 23 is bent into .a circular configuration at right angles .to the spiral member 23 with the free end 25 of the base member 22 secured to the bottom of the spiral member in any suitable manner, such as by welding. Thus the base member 22 formed from a single piece of-materialis prefthe vacuum cleaner.

erably of circular configuration having a spirally twisted portion formed integrally therewith and projecting therefrom in a plane at right angles thereto.

The base member or portion 22 is formed with an upwardly projecting portion 26, Figure 3, which is adapted to straddle the switch 20 when the base member 22 is placed upon the ledge of the upper cover portion 11 of the casing. The projecting portion 26 in cooperation with the switch anchors or secures the base member 22 against rotative movement with respect to the casing of A plurality of supports or members 27 for holding the vacuum cleaner attachments or tools are secured to the base member 22 in spaced relation with one another. While the tool supports or members 27 may be formed of various shapes or configurations and from different types of material it has been found from experience that tool supports formed from a single piece of material, such as wire, provide a support which is light in weight yet sufficiently strong and rigid to adequately support and retain the vacuum cleaner tools. As shown in Figure 2 the supports 27 are formed from a single piece of wire with the ends of the piece of wire being secured to the base member 22 in spaced parallel relation to one another. The ends of the Wire of the supports 27 may be secured to the base member 22 in any suitable manner, such as by welding, and are positioned in a plane at right angles to the base member 22 so as to extend in an upward direction therefrom. The upper ends 28 of the supports 27 may be formed or bent into any desired shape, such as flat or arcuate, depending upon the particular type of tool that is to be mounted thereupon.

Thus the projecting portion 26 of the base member 22, the spiral member 23 and supports 27 all project or extend from the same surface of the base member 22 and are positioned in planes at right angles to the base member. The entire base member 22 and projecting portion 26 together with the portions of the spiral member 23 and supports 27 adjacent the base member are encased in a rubber sheathing 30. The rubber coating or sheathing 30 may be applied in any suitable manner, such as by a dipping operation.

In mounting the tool or attachment holder shown in Figure 2 upon the vacuum cleaner shown in Figure 1 the base member 22 is placed upon the ledge 15 of the upper portion 11 of the casing adjacent and surrounding the portion 14 with the projecting portion 26 of the base member straddling the switch 20. Thus the base member is positioned on the outer casing of the vacuum cleaner in a plane substantially parallel to a plane through the horizontal medial axis of the vacuum cleaner. When the base member 22 is positioned upon the ledge 15 the tool supporting members 27 will project upwardly from the base member along and about the outer casing of the vacuum cleaner. Thus the tool supporting members 27 tend to lie alongside of but in a slightly spaced relation to the outer casing of the vacuum cleaner.

The base member 22 is of approximately the same diameter as the diameter of the projection 14 and due to the inherent resiliency of the material constituting the base member said base member is retained in engagement with the portion 14. The rubber sheathing 30 on the base member 22 also aids in insuring the retention of the tool holder on the cover portion 11 so that when the upper casing portion 11 is removed from the lower casing portion 10, through the medium of the handle 18, the tool holder in its entirety, with the tools mounted thereon, will be removed along with the upper cover portion of the casing. The configuration of the tool holder and its manner of mounting upon the casing portion 11 insures that the tool holder, with the various tools thereon, will remain thereon even when the casing portion 11 is lifted from the casing portion 10 and placed upon a support such as a floor.

The supports 27 are preferably formed of such size and shape as to support the various attachments or tools and the inherent resiliency of the material from which the supports 27 are formed tends to provide a snug fit between the tools and supports. The rubber sheathing 30 on the lower portion of the supports 27 also tends to aid in the retention of the tools upon the supports even when the upper casing portion 11 and tool holder are placed upon the floor at an angle of approximately 45 degrees. At the time that the base member 22 of the tool holder is being placed upon the upper casing portion 11 the cord 31, Figure 1, for the vacuum cleaner motor is fed through the spiral member 23 and when the vacuum cleaner is stored the cord is looped about the hook 24. The spiral member 23 tends to retain the portion of the electric cord 31 adjacent the vacuum cleaner in an upright but flexible position so as to diminish the possibility of the cord becoming entangled in the cleaner when it is being emptied.

Referring to Figures 4 and 5 there is shown a modified form of the attachment or tool holder of the present invention as applied to a horizontal tank type vacuum cleaner. The vacuum cleaner shown in Figures 4 and 5 comprises a generally cylindrical casing mounted upon suitable runners 41 to facilitate moving the cleaner during a cleaning operation. The casing 40 encloses a conventional dust bag, electric motor and suction fan, not shown, and at one end is provided with a suction inlet 42 to which the customary hose is attached. An elongated rigid handle 43 is secured to the top surface of the casing 10.

The attachment or tool holder, shown in Figures 4 and 5, comprises a base portion or member 45 in the form of an endless band which is preferably formed from a single piece of inherently resilient material, such as wire. The base member 45 is substantially rectangular in configuration and is so formed as to provide two side segments or legs 46, a front segment or leg 47 and a pair of rear segments or legs 48 which are the ends of the piece of material from which the base member is formed. The side legs 46 of the base member 45 are disposed on opposite sides of the casing 40 in a plane substantially parallel to a plane through the horizontal medial axis of the casing. The side legs 46 are joined together at their forward ends by the front leg 47 which is bent slightly toward the rear legs 48. The front leg 47 throughout the greater portion of its length is of an arcuate configuration to conform to the contour of the casing 40. The middle or central portion is formed with a pair of flat segments 49 which rest upon the top surface of the casing 40 along side of the forward end of the handle 43. The flat segments 49 of the forward leg 47 terminate in upwardly extending portions 50 which project inwardly towards one another under the handle 43 and are then bent forwardly into a common apex 51 which extends under and toward the forward end of the handle 43, as shown in Figure 4. The rear ends of the side legs 46 are joined together by the rear legs 48 wherein one of the rear legs terminates in an eyelet 52 for receiving the end 53 of the other rear leg, Figure 6. The rear legs 48 are of arcuate configuration to conform to the contour of the casing 40 and the ends 52 and 53 are connected together under the rear end of the handle 43. The rear legs 48 when connected together are maintained under tension and by positioning the central portion of the forward leg 47 under the front end of the handle 43 and the ends of the rear legs under the rear end of the handle the tool holder is maintained in position on the casing 40 when the vacuum cleaner is in use or when it is in storage and standing in a vertical position on the rear end 54 of the casing 40. The configuration of the front leg 47 and the rear legs 48 conforming to the contour of the casing 40 and the manner in which the projections 49, 50 and 51 of the front leg 47 are positioned under the handle 43 insure that the base member 45 will be so supported on the casing 40 as not to have any rotative movement with respect to the casing.

The base member or portion 45 is provided witha plurality of spaced supports or members 56 for holding the vacuum cleaner attachments or tools. The tool holding members 56 are of substantially the same shape and size as the tool holding supports 27 shown in Figure 2 and the tool holding members 56 are secured to the base member 45' in the same manner and relation as the members 27 are secured to the base member 22 of Figure 2. The tool holding supports 56 when secured to the base member 45 are slanted slightly, Figure 4, towards the front leg 47 so that when the vacuum cleaner casing 1 is placed in an upright position on the end 54 for storing or emptying the dust bag the tools or attachments will be retained on the members 56. When the base member 45 is positioned upon the casing 49 the tool supporting members 56 will project upwardly from the base memher and along and about the casing 46 but in a slightly spaced relation thereto.

The base member 45 has secured thereto adjacent the junction of one of the side legs 46 and one of the rear legs 43 a spiral cord guide member 57 which terminates; in an outwardly extending hook portion 5'8 for sup porting an electric cord 59 in the same manner as the hook portion 24 of Figure 2. The spiral member 57 is secured to the base member 45 in the same manner as the supports 56 and is disposed in a plane at right angles to the base member 45 in the same manner as the sup ports 56. The base member 45, spiral member 57 and tool holding members 56 are encased in a rubber sheathing in the same manner as disclosed with the tool holder shown in Figures 1 and 2. It is to be understood that instead of applying a rubber coating to only the portion of the tool holding attachment as described in connection with Figures 2, 4, and 5, that the entire tool holding attachment may be encased within a rubber sheathing.

In the modified form of the invention shown in ure 7 the base member 60 and tool holding members 61 are formed from a single piece of material, such as wire. In this form of the present invention the base member 60 is formed with a plurality of vertically spaced loops which are integral with the base member and adapted to support tools.

The tool holding attachment of the present invention is so designed as to place the tools or attachments upon a vacuum cleaner within easy reach of the operator and yet the tools are so mounted on the holder that they will remain in place during a cleaning operation or when the cleaner is being emptied or is stored.
