Definitions
- a suction tool having a plurality of spaced narrow, hollow nozzles depending from the body of the tool and elongated in a horizontal direction parallel to the normal forward and backward horizontal movement of the tool.
- the lower surfaces or lips of these nozzles are curved upwardly at their opposite ends and the interior surfaces of the nozzles adjacent their opposite ends are convexly curved.
- the hollow nozzles communicate with the interior of the body of the tool, which in turn is connected through the usual hollow wand or handle and flexible hose with a source of suction in a vacuum cleaner unit.
- This construction enables the several nozzles to penetrate the deep pile of a shag rug by parting the fibers and thus the nozzle openings are brought fairly close to the base of the rug and the air flow into the nozzles is able to entrain deeply embedded dirt.
- the shape of the nozzles enables them to be moved with reasonable ease between and over the fibers and to comb out the fibers as the tool is moved.
- the fibers forming the pile are exceeding long, usually several inches, thus making vacuum cleaning of such a rug very difficult.
- the ordinary suction nozzle which is elongated in a direction at right angles to the normal direction of the movement of the nozzle, resists movement over the rug as the lips of the nozzle tend to dig into the pile and in addition, the long fibers are drawn into the nozzle and the interior configuration of the latter is such that the fibers are not readily withdrawn.
- the nozzle opening is held so far above the base of the rug as to prevent the air flow from penetrating deeply enough to remove deeply embedded dirt.
- a suction nozzle provided with a motor-driven rotary brush has all the above disadvantages, and in addition the long fibers are apt to get wrapped around the brush and the rotary brush causes undesirable fuzzing or untwisting of the rug fibers.
- the suction tool in accordance with the present invention because of the plurality of spaced relatively narrow nozzles elongated in a direction parallel to the direction of movement of tool, is able to penetrate the fibers and bring the suction openings close the the base of the rug.
- the exterior contours of the nozzles enable them to part the fibers so that the tool may be moved without difficulty back and forth, and the interior contour makes it easy to withdraw fibers which may be drawn into the nozzles.
- the combing action of the narrow nozzles gives an attractive appearance to the surface of the rug.
- suction openings are formed in the body of the tool between the spaced nozzles so that air may be admitted from adjacent the upper surface of the fibers for entraining surface litter, and valve means are provided for regulating flow through these openings and the nozzles, respectively.
- FIG. 1 is a prospective view of a suction tool in accordance with the present invention
- FIG. 2 is a front view of the tool shown in FIG. 1;
- FIG. 3 is a cross-sectional view taken on the line 3 of FIG. 2;
- FIG. 4 is a cross-sectional view taken on the line 4-4 of FIG. 3;
- FIG. 5 is an elevational view looking towards the left in FIG. 4;
- FIG. 6 is an exploded view of a cleaning tool in accordance with a second embodiment of the invention.
- FIG. 7 is a cross-sectional view of a still further embodiment of the invention.
- reference character 10 designates the hollow body-of suction cleaning tool the interior of which may be connected to a source of suction in a vacuum cleaner through an elbow 12 which is rotatably mounted in the body.
- One face of the body is formed with an elongated suction opening 14 bounded along its sides by parallel lips 16 and 18 and at its ends by gliding pads 20 and22 which extend outwardly beyond the lips.
- each nozzle terminates in lips 26 bounding a suction opening 28 and the lips extend a greater distance rearwardly of the tube or shank portion 30 of each nozzle than forwardly thereof.
- the lips are curved upwardly at opposite ends of the nozzles, similar to runners of a sleigh, while the tube or shank portions 30 are contoured so as to have curved forward and rear surfaces 32 and 34, respectively as is shown in FIG. 4.
- the interior of each nozzle is contoured so as to provide smoothly curved surfaces 36 and 38 connecting the tube or shank portion 30 with the lower elongated nozzle portion.
- the angle between the line A representing a surface on which the nozzle 24 is resting and the inner surfaces of rear lip portion may be approximately 20.
- the elbow 12 also serves as arotary valve to connect either the nozzles 24 or the suction opening 14 to the interiorof the elbow and hance to the source of suction.
- the cylindricalportion of the elbow which is within the body 10 is formed with a cutaway section 40 which cooperates with partitions 42 and 44. With the parts in the position shown in FIG. 3, air may flow through the nozzles 24 into the body below partition 42 and through the cut-away section 40 into the elbow.
- the body 10 is rotated about the elbow, so as to bring the lips 16 and 18 and the pads 20 and 22 into operative position on a rug, the air flows through the suction opening 14, along the outer surface of partition 44 and through cutaway portion 40 into the elbow.
- suction is applied to which ever side of the tool is in contact with the rug.
- the body 10 is rotated so as to bring the elongated suction opening 14 into operative position on the rug. Because of the large surfaces presented by the wide lips 16 and 18 and the pads 20 and 22, the tool may be moved back and forth over the long fibers of the deep pile and the in-rushing air will entrain dirt and litter at the upper surface of the rug. However, due to the deep pile, very little if any air will be moved down in the neighborhood of the back of the rug, and practically no embedded dirt will be removed.
- the body 10 In order to pick up this type of dirt, the body 10 is rotated so as to bring the nozzles 24 into operative position. If the tool is now moved back and forth the nozzles, being narrow and elongated in the direction of this movement, will sink down into the pile and may be moved without much resistance between the fibers. Such movement is also facilitated by the curved runner-shaped lips 26 and the curved surfaces 32 and 34 on the exterior of the shank portions 30. In this way the suction openings 28 of the nozzles 24 are brought close to and moved over the upper surface of the back of the rug and the flow of air thus produced at this surface is able to entrain and remove deeply embedded dirt. This air flow sucks some of the long fibers into the nozzles 24, but due to the smooth curved interior surfaces 36 and 38, the fibers to not get caught therein, but come out without resistance as the nozzle is moved along.
- the cleaning tool shown in FIG. 6 instead of having a surface litter suction opening on one side of a rotatable tool and the embedded dirt nozzles on the other, both are on the same side and slide valve serves to direct air flow through one or the other.
- the tool comprises an upper body part 50 having an elbow 52 for connecting the tool to a source of suction, and a lower body part 54 carrying the spaced nozzles 24. Between the nozzles the lower body part is formed with suction openings 56 and a slide valve 58 having valve ports 60 is slidably mounted between the upper and lower body parts.
- the ports are so porportioned and spaced that they may be aligned with either the openings 56 or the interior of the nozzles 24, the valve 58 being somewhat longer than the body parts 50 and 56 so that one end or the other of the valve extends beyond the body and may be moved manually lengthwise so as to alter the valve setting.
- the openings 56 may be progressively larger towards the ends of the suction tool in order to compensate for the fact that they are located further from the elbow 52.
- valve 58 In operation, if it is desired to remove surface litter, the valve 58 is set so that its ports 60 are aligned with openings 56 and hence all the air will enter through these openings, the nozzles 24 being closed by the solid part of the valve. For deep embedded dirt cleaning, on the hand, the valve 58 is shifted so as to close the openins 56 and align the ports 60 with the nozzles 24 whereby all air is drawn in through the nozzles.
- FIG. 7 there is shown an embodiment in which the valve for regulating the air flow is so arranged as to be shifted automatically, thus relieving the operator of the necessity of doing this.
- the body 70 of the tool is divided into a forward chamber 72 and rear chamber 74 by a partition 76.
- the bottom of the forward chamher is formed with one or more surface cleaning suction openings 78 while the spaced nozzles 24 depend from and communicate with the rear chamber.
- the elbow 80 which serves to connect the tool to a source of suction, also constitutes a tubular slide valve having ports 82 in its side near its forward end.
- the valve extends through the rear wall of chamber 74 and through partition 76 and is formed at its front end with a radial flange 84 and near its other end with a similar flange 86, the flanges being spaced by a distance greater than that between the partition 76 and the outer surface of the rear wall of chamber 74.
- a hollow elongated body for connecting the interior of said body to a source of suction, and a plurality of spaced hollow tubes depending from said body and communicating with the interior thereof, the lower end of each tube terminating in a suction nozzle elongated in a horizontal direction substantially at right angles to the horizontal lengthwise extent of said body, the length of each nozzle being substantially greater than the dimension of the tube in a direction parallel to the length of the nozzle.
- each nozzle being less than the spacing between the nozzles.
- each nozzle being bounded by lips which curve upwardly at the opposite ends of the nozzle.
- each nozzle extending a greater distance rearwardly of said elongated body than forwardly thereof.
- each tube and nozzle being contoured to provide smoothly curved connecting surfaces.
