".llools, of which the following is a specification.
My invention relates to suction cleaning tools and has for its primary object the provision of an improved tool of this class, which shall have improved means for cleaning the surface to which it is applied.
With the above and other objects in view, this invention consists substantially in the combination, arrangement and construction of parts, all as hereinafter described, shown in the accompanying drawings, which form a part of this specification and illustrate the preferred embodiment of my invention, and more specifically set forth in the subjoined claims.
In the drawings: Figure 1 is a vertical longitudinal section of my invention, showing in front elevation-a casting to which it is attached; Fig. 2 is a side elevation of my invention with parts thereof broken away; Fig. 3 is a vertical transverse section taken on the line 3-3 of Fig. 2, and looking in the direction indicated by the arrows; Fig. l is a vertical transverse section taken approximately on the line l-Ll of Fig. 2, and looking in the direction indicated by the arrows; and Fig. 5 is an en d view of my invention.
Reference numeral 10 of the drawings indicates the nozzle of my 'improved cleaning tool, which may be attached to an exhaust, either by being formed integrally with a fan casing 11, as shown in Fig. 1, or shaped into a hose connection 12, as illustrated in Figs. 2, 4 and The nozzle 10 is shaped to form a chamber/ 13, in which is positioned an oscillating brush generally indicated by the letter A. Inwardlv extending bosses 14 and 15 are formed in the ends of the nozzle 10 and carry adjustable pins 16 and 17, slotted as at 18 for engagement with a screw driver or other tool, and provided with eccentric, inwardly protruding studs 19, the pins 16 and 17 being secured in any adjusted position by means of set screws 20, or other convenient fastening means. Preferably, however, the fastening means is contained within the casing 10, in orderthat the outer ends thereof may bear no protruding parts.
The brush A consists of a brush core 21,
preferably cylindrical in form and socketed at its ends for engagement with the studs 1i). Positioned upon the core`21 are two lines 22 and 23 of bristles, substantially diametrically opposite each other and extending longitudinally of the core. A stud or other suitable projection 2-1 protrudes from the side of the core, and in its path of oscillation lie two detents 25 and 26, preferably formed upon the inner face of the nozzle 10. An arrow 27, shown in Fig. 4, indicates the direction of the exhaust, or, in other words the direction which air and particles of dirt travel when the suction tool is in use. The projection 24 is so positioned upon the core 21 that when the suction tool is traveling over a surface to be cleaned in the direction of the arrow marked 28, in Fig. 4, the line of bristles 23 will point toward and contact with the article being cleaned, while the line of bristles 22 will be turned in an opposite direction, pointing in the direction indicated bv the arrow 27, thus lying with their free ends pointing along the path of exhaust and therebyin a position to be cleaned of all lint and other matter caught between them. `While the cleaning tool proceeds in the direction indicated by the arrow 28, the contact between the projection 24 and the st-ud 2G maintains the bristles in the above-described position. `When the direction of travel of the nozzle, however, is reversed, the position of the lines of bristles 22 and 23 is likewise reversed, thereby bringing the line of bristles 22 into contact with the article being cleaned, and positioning the line of bristles 23 in such manner that they will be cleared of matter which has been caught between them. To positively accomplish this reversing of position of the lines of bristles 22 and 23, any suitable medium may be provided, such, for instance, as the single sets of bristles 29 and 30 which, contacting with the article being cleaned, draw the lines of bristles around to their reversed position.
By rotation of the pins 16 and 17 within the bosses 14 and l5, relative adjustment is had between the nozzle 10 and the brush A. Centered and rotatably mounted upon the studs 19, and positioned between the bosses 14, 15 and the brush core 21 are two rollers 31 and 32. Relative adjustment is had between these rollers and the nozzle 10 in the same way as between the brush A and the nozzle 10; that is, by rotation of the pins 16 and 17 Within their respective bosses 14V and 15. For convenience in indicating the proper amount of rotation to be given to the pins 16 and 17, the outer ends of the nozzle 10 are provided, as shown in Fig. 5, With graduations 33, 34 and 35, and a mark 36 is placed upon the exposed end of each pin. The graduations 33, 3-1 and 35 may be designated by suitable legends, if desired, such for instance as the letter U for up, M for medium, and D for down. When the parts are in the position shown in the drawings, the mark 36 registers with the graduation 33."When it is desired to lower the brush relatively to the nozzle 10a screw driver or other tool is applied tothe slots 18 and the pins 16 and 17 are rotated until the mark 36 registers with the graduation 35. If an intermediate position of the brush is desired, the mark 36 may be caused to register with the graduation 34. Any other desired indicating device may be employed, but it is preferable that the device be one which, as is disclosed in the drawings, carries no parts protrudingl outwardly from the ends of the nozzle 10.
An advantage of my invention lies in the simultaneous adjustment of the rollers 31 and 3:2 with the brush.
In the accompanying drawings and in the foregoing description is set forth the preferred embodiment of my invention, but it is obvious that one skilled in the art may make modifications thereof Without departing from the principle of the invention'.
l. The combination with an exhaust, of a cleaning tool connected therewith, comprising a nozzle, a reversible brush mounted in the nozzle for oscillation only, means contacting with an article to be cleaned for reversing thebrush when the direction of travel of the tool is reversed, and means for holding the brush stationary in either of its positions during the travel of the tool in one direction.
2. The combination with an exhaust, of
va cleaning tool connected thereto, comprising a. nozzle and a reversible brushmounted in the nozzle for oscillation only, said brush comprising a core and opposite lines of bristles longitudinally disposed.
3. The combination With an exhaust, of a cleaning tool connected thereto, comprising a nozzle, a reversible brush positioned in the nozzle for oscillation only, said brush comprising a core and opposite lines of bristles longitudinally disposed, and means upon the brush adapted to contact With an article being cleaned to reverse the brush.
4. The combination with an exhaust, of a cleaning tool connected thereto, comprising a nozzle, an oscillating brush positioned in the nozzle, stops upon the nozzle, and a detent upon the brush coperating With the stops to limit the, oscillation of the brush.
5. The combination with a suction cleaning tool having a nozzle, of a nozzle upon.
the tool, a reversible brush positioned in the nozzle, said brush having opposite longitudinal lines of bristles one of said lines of bristles being adapted to contact with an article being cleaned and the other line being adapted to point toward the direction of exhaust When the cleaning tool is drawn in one direction, means for maintaining the lines of brushes in said position during the continuation of the tool in said direction, means for reversing said positions of the lines of brushes when the tool is drawn in the opposite direction. and means for maintaining the linesof brushes in the reversed position during the continuation of the tool in the opposite direction.
6. The combination with an exhaust, of a cleaning tool connected thereto, comprising a nozzle. a reversible brush positioned in the nozzle, rollers ypositioned in the nozzle, and means for adjusting thebrush and rollers simultaneously with respect to the nozzle.
7. The combination in a suction cleaning tool having a nozzle, of a reversible brush mounted in the nozzle for oscillation only, rollers co-axial with the brush and mounted for rotation in the nozzle, and adjustable bearings for the brush and rollers mounted in the nozzle, said bearings being entirely Within the outer surface of the nozzle.
In testimony whereof I have signed my name to this specification, in the presence y of two subscribing Witnesses, on this 17th day of April, A. D. 1913.
