SUCTION CLEANING TOOL Filed Nov. 28, 1949 Inventor N. A. BUCCASIO Patented June 30, 1953 UNITED ST ATENT OFFICE 6 Claims.

This invention relates to improvements in suction cleaning tools, and more particularly to a suction cleaning tool adapted to be attached to the suction hose of a vacuum cleaner or other source of partial vacuum. While particularly designed and having special utility as a tool for cleaning the slats of Venetian blinds, it is also applicable as a general cleaning tool for removing dust from places or objects which are difficult of access and/or which present a multiplicity of surfaces likely to accumulate dust.

Among the objects of my invention may be noted the provision of a suction cleaning tool capable of attachment to any of the standard makes of vacuum cleaners, which is charactericed by inexpensive construction, and which is efficient in operation, as well as thoroughly dependable in use. Another object ofthe inven tion is the provision of a suction cleaning tool as aforesaid which is particularly effective in removing the dust accumulating on the slats of Venetian blinds, while at the same time functioning as a general utility cleaning tool for removing dust from objects or surfaces dimcult of access. A further object of the invention is the provision of a suction cleaning tool in the nature of an attachment for a standard vacuum cleaner, incorporating a novel form of suction head capable of concentrating the suction effect in a relatively small area of the surface or surfaces to be cleaned while at the same time being readily movable along said surface whereby rapid cleaning may be effected. Yet another object of the invention is the provision of a suetion cleaning tool as aforesaid, which is constructed and arranged as to permit the suction effect to be varied as desired simply by tilting or slanting the tool with respect to the surface to be cleaned. A further important object of the invention is the provision of a suction cleaning tool capable of being readily moved along a surface to be cleaned but which will not mar or scratch said surface.

The above and other objects and advantages of the invention will be seen from the following detailed description thereof, taken with the accompanying drawings illustrating preferred physical forms which the invention may take, in which Fig. l is a broken-away edge view of one form of suction cleaning tool according to the inventicn;

Fig. 2 is an under face View looking into the suction head;

a new covering substituted therefor.

Fig. 4 is a separated view illustrating a modifled construction of suction cleaning tool according to the invention;

Fig. 5 is a longitudinal section taken through the assembled tool of the form illustrated in Fig. 4; and

Fig. 6 is a perspective view illustrating one ap= pllcation of suction tools of the invention.

Referring to the drawings in detail, and more particularly to the form of suction cleaning tool illustrated in Figs. 1-3, such preferably cornprises a tubular body member 8 having a circular handle end I ii and a flattened blade-like tool end 82, which latter extends for the major length of the body member as seen in Fig. 6 and is comprised by substantially parallel walls joined along their side edges. The flattened or blade-like end 12 of the tool body terminates in a point I4 and aids in forming a suction head generally designated l6 (Fig. 2), which has length about equal to the width of a convention a1 Venetian blind slat and proportional width. Said suction head it is formed by an underface portion of one wall [2a of the flattened or bladelike end of the tool body and by a flange or bead l8 which extends from the point i l of the tool body along the side edge margins thereof for an appreciable distance, and thence across said flat wall. Thus, the bead I8 forms with the underface portion of the flat wall portion lla of the tube which it bounds a suction recess or enclosure which is supplied with vacuum through a multiplicity of vacuum openings as provided in the enclosed portion l2a, of the tube wall, as shown in Fig. 2. Said vacuum openings are shown to be circular but they may take other forms, such as narrow slots, or one large suction opening may be employed.

According to a further feature of the invention, the bead I8 is preferably covered with a soft material such as felt, wool, short-pile fabric, and the like. The covering 22 is preferably preformed to channel section, and stiffening or reinforcement may be supplied so that the cove ing may be slipped over the bead, whereupon it frictionally attaches itself to the bead. To aid in securing the covering, the inner wall of the bead may be undercut as indicated at 2% (Fig. 3), thus to provide a relatively wide edge or rim, behind which the channel-shaped covering may secure itself. Such a slip-on covering permits it to be detached from the bead when worn and It is also within the purview of the invention to positively secure covering 22 to bead I8 by adhesive, spring clips, or like positive securing means. When properly applied, the covering 22 partially or semi-seals the suction recess or enclosure of the suction head to atmosphere and it also serves the additional functions of disturbing the dust to be removed from a surface and of permitting the head to be moved rapidly across said surface without marring or scratching the same.

The form of suction cleaning tool illustrated in Figs. 1-3 may, except for the head covering 22, be cast integrally from any suitable plastic material or from a light-weight metal such as aluminum, the suction apertures 29 being formed in the molding operation or in a subsequent drilling operation. The tubular body member 8 may also be formed from a suitable pressed material and the head bead l3 molded or otherwise formed in a separate operation and thereupon secured to the flattened end 52 of the body member by cementing or other appropriate means.

Referring to the modified: tool construction illustrated in Figs. 4 and 5, here the hollow, bladelike tool end 28 and the head head 38 are formed separately, and the head bead is provided on a hood generally designated 3% which is adapted to he slipped on to the pointed and perforated end of the tubular body member to which it secures itself by friction. In such modified construction, the hood 3% maybe formed from lightweight sheet metal, being provided with a back ing 32, marginal side flanges 3d, 36 and an angled end flange 46 converging to a point :2. Said hood is effectively open at one end to receive the pointed end of the flattened tube section and the side and end flanges 34, 36, it of the hood are substantially deeper than the flattened end of the tool body, with the result that when the tool parts are assembled as shown in Fig. 5, said flanges depend from the under face of the tube end. Said flanges preferably terminate in rightangular edge rims or beads M functioning as the rim enlargement 26 provided by the undercutting of the earlier described bead it.

To complete the suction recess or enclosure upon the hood being slipped over the pointed end of the flattened-tube body member a transverse strip 46 is provided to extend between the ends of the side flanges 34, 35, the under edge of the strip being spaced from the face of the backing 32 approximately the depth or thickness of the tool body, thus providing an entry slot for the tool body. The transverse strip it is formed with an edge rim or bead l la forming a continuation of the similar bead id of the hood sideflanges 3 3, 3%, and said edge rims or beads are covered, either prior to or after the assembly operation, with a preformed covering it corresponding to the previously described covering 22, with the result that a suction head is formed by the separate hood and flattened end of the tubular body member which functions similarly to the first described form of suction head. The transverse strip may be fixed before assembly to both ends of the side flanges 35, 35, or the strip may be affixed, either integrally or by an approved form of attachment, to only one of the side flanges, and bent to final position and attached as by clipping or soldering to the end of the other side flange, upon the hood being slipped over the pointed end of the tubular body me i.- ber 28.

In use, a suction cleaning tool as described is connected to the suction hose of a vacuum cleaner, or to an extension fitting connected to said suction hose. The head with the suction recess opening downwardly may be placed flat on the surface to be cleaned, the bead covering 22 (or, 48) providing a semi-seal to atmosphere and functioning to concentrate suction within the suction recess bounded by the head or flange, with the result that any dust particles on the surface are drawn through the head and into the suction hose, following which they are disposed of in the usual manner. The semi-seal formed by the bead or flange covering, although concentrating suction in the bead enclosure as aforesaid, permits the head to be readily moved along the surface to be cleaned, the covering also disturbing any dust tending to adhere to the surface so that it may be readily picked up by the suction eifect and drawn out through the head. When used in cleaning the slats of Venetian blinds, the point on the suction head is of advantage in that it facilitates getting to and around the tapes usually securing the blind slats together, as well as the more inaccessible parts of the slats. It is also possible to vary the suction effect by tilting the tool slightly, so that it makes contact with the slat or other surface only along one side or margin of the bead. This tilting may result in some lessening of the vacuum effect, but it is effective to speed up the cleaning operation as it permits the suction head to be moved rapidly back and forth across a surface requiring cleaning.

Without further analysis, it will be seen that the suction cleaning tool of this invention achieves the desirable objectives set forth in the foregoing. Due to its simple design and construction, it may be manufactured inexpensively. It provides an effective means for rapidly cleaning the slats of Venetian blinds and is equally adaptable as weil as a general cleaning tool for removing an accumulation of dust from relatively inaccessible surfaces. Moreover, the suction cleaning tool as described is thoroughly dependable in use and is capable of effecting a rapid cleaning operation without danger of marring or scratching hard surfaces such as those of the slats of Venetian blinds and the like.

As many changes could be made in carrying out the above constructions without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
