Francis A. Gall WITNESS" r 1 v MWW 829 ATTORNEY United States Patent M RADIATOR TOOL AND BRUSH COMBINATIONS FOR VACUUM CLEANERS Application December 16, 1953, Serial No. 398,501

3 Claims. (Cl. 15328) This invention relates to vacuum cleaners and more particularly to an improved combination radiator tool and brush adapted for use at the end of a hose for cleaning radiators and upholstery and for dusting; the primary object of the invention being to provide an improved device of this character.

Another object of the invention is to provide a radiator type cleaning tool having an improved brush that may easily be attached to or removed from the tool.

A still further object of the invention is to provide a radiator type cleaning tool that may quickly be transformed into an upholstery cleaning nozzle or into a dusting brush.

Another object of the invention is to provide an improved vacuum cleaner tool which ha many diiferent uses.

With the above and other objects in view, as will hereinafter appear, the invention comprises the devices, combinations and arrangements of parts hereinafter described and claimed.

The features of the invention and advantages attained thereby will readily be understood from the following detailed description of a preferred embodiment of the invention illustrated in the accompanying drawings in which:

Fig. 1 is a front elevational view of a cleaning tool embodying the invention,

Fig. 2 is a top view of the tool shown in Fig. 1,

Fig. 3 is a bottom view of the tool shown in Fig. 1,

Fig. 4 is a view similar to Fig. 1 except that the brush has been removed and the slider, as shown in solid lines, has been moved to open position,

Fig. 5 is a top view of the device shown in Fig. 4,

Fig. 6 is a sectional view taken on the line 66 of Fig. 1,

Fig. 7 is a sectional view taken on the line 7-7 of Fig. 4.

As seen in the drawings, the combination tool of the present invention comprises a member 10 of the type generally referred to as a radiator tool. The radiator tool 10 has a cylindrical tubular portion 11 which is of proper size for connection to the free end of a flexible hose (not shown) which, in turn, may be connected to the intake mouth of a vacuum cleaner (not shown). At a location indicated by the numeral 12, the cylindrical portion 11 blends into an oval tubular portion 13 having two flattened side walls 14 and 16 and two curved side walls 17 and 18. The free open end of the oval portion 13 is cut on a bevel 19 of approximately forty-five degrees (45) to provide the characteristic thin pointed suction mouth 21 usually associated with radiator tools.

The present device differs from ordinary radiator tools heretofore manufactured in that, first, one of the flattened sides 16 is provided with three oblong apertures 22, 23 and 24, second, a slider 26 is slidably mounted on the outer face of the wall 16, and, third, the oval portion 13 is provided with means for mounting a dusting brush 27.

As best seen in Fig. 1, the apertures 22, 23 and 24 are 2,811,738 Patented Nov. 5, 1957 staggered so that aperture 22, which is located-nearest to the tubular portion 11, is adjacent to the curved wall 18, whereas the aperture 23, which is next remote from the portion 11, is located adjacent to the curved wall 17, and the aperture 24, which is nearest the beveled end 19, is adjacent to the curved wall 18. The slider 26 is in the form of a flat plate having parallel upper and lower edges 28 and 29, one square end edge 30 and one beveled edge 31, the latter having a forty-five degree (45) slope so that the edge 31, as seen in Fig. 4, may extend parallel to the beveled end 19 of the oval tube 13. The slider 26 is provided with three oblong apertures 32, 33 and 34, these apertures being staggered in the same manner as the corresponding apertures 22, 23 and 24 are staggered and positioned so that when the slider 26 is moved to the position shown in solid lines in Fig. 4, the apertures 32, 33 and 34 in the slider 26 will be aligned exactly with the corresponding aperture 22, 23 and 24 in the wall 16. The slider 26 is slidably held to the wall 16 of the tubular portion 13 by means of a pair of headed rivets 3636 which are secured to the slider 26 and pass through a pair of colinear slots 3737 in the wall 16. The heads of the rivets 36-36 are larger than the width of the slots 3737 and thus the slider 26 is held against the wall 16. The slider 26 is provided with a roughened thumb-engaging pad 38, thus facilitating the movement of the slider 26 along the wall 16. As best seen in Fig. 4, the length of the slots 3737 are such that when the slider 26 is moved to the position where apertures 32, 33 and 34 align with the apertures 22, 23 and 24, the rivets 36-- 36 are located in one end of the slots 3737, whereas when the slider26 is moved to the position (Fig. 1) so that the apertures 22, 23 and 24 are covered by the slider 26, the rivets 36+36 are at the other end of the slots 3737.

In order to support the dusting brush 27, the radiator tool 10 has been modified by, (a) the attachment of a headed pin 41 to the curved side 17 adjacent to the place 12 where the side wall 17 blends into the cylindrical por tion 11, (b) the formation of a notch 42 at the place where the side wall 17 ends and the beveled mouth 21 begins, (c) the forming of a notch 43 at the extreme pointed end of the mouth 21, and (d) the provision of a small hole (44) in the curved side 18 close to the notch 43. The brush 27 is formed from a stiff spring wire 46 bent back on itself and twisted together to support a multiplicity of bristles 47 which radiate from the twisted wire 46 in an arc, as seen in Fig. 6, of approximately two hundred and eighty degrees (280). In general the brush 27 is J-shaped in form and a short tightly twisted unbristled free end 48 of the twisted wires enters the hole 44. The end 48 is disposed at an angle of ninety degrees with respect to an unbristled portion 49 and a bristled portion 59. The sections 49 and 50 are disposed at an angle of 90 with respect to a bristled section 51. The section 51, which may be termed a link section, is disposed at an angle of 90 with respect to a bristled section 52. When the brush 27 is removed from and thus unsupported by the tool 10, the section 52 is disposed at an angle of approximately one hundred and fifty-five de grees with respect to a bristled section 53 which ends in a small unbristled section 54 having a free-end loop 56. However, when the brush 27 is installed on the tool 10, the section 53 is flexed downwardly from the dotted position shown in Fig. 1 to the position shown in solid lines in Fig. 1 which shows sections 53 and 54 to be parallel with the side wall 17. When this is done, the loop 56 is sprung over the headed pin 41 in such a manner that the sections 53 and 54 are held parallel to the side wall 17. This locks the brush 27 to tool 10 in such a manner that it will not be released during normal use of the tool and brush. This downward flexing causes the brush section 53 to' become substantially colinear with the brush section 52 and causes the brush section 53 to become parallel with the brush section 50, which is also parallel with the brush section 52.

'Persons versed in the.art .will appreciate that the above described device may be used in several different ways. For example, when the brush 27 is removed from the tool and the slider 26 is moved to close the apertures 22,, 23 and 24 the tool becomes an ordinary radiator'tool. This is clearly indicated by the dotted position of the slider 26 in Fig. 4. If the slider 26 is moved to the position shown in solid lines in 'Fig. 4, the apertures 32, 33 and 34 in the slider 26 will align with the apertures 22, 23 and 24 and the tool is converted into an upholstery nozzle. If the slider26 is moved to close the apertures 22, 23 and 24, and the brush. 27 is attached in a manner shown in Fig. l the tool is converted into a dusting brush. If the slider 26 is moved from the closed position shown in solid lines in Fig. 1 to the position indicated by dotted lines, the apertures 32, 33 and 34 align with the apertures 22, 23 and 24 and the tool is converted into an upholstery nozzle provided with a dusting brush.
