11 Claims.
This invention relates to cleaning upholstery and other materials, especially those of a character to be cleaned most conveniently by moving a portable cleaning device over the surface 01 the work.
An object of the invention is to provide simpleand easily manipulated means for treating with a cleaning liquid the material being operated upon, progressively, by moving a cleaning device over its surface in a manner analogous .to the operation of a vacuum cleaner. To this end, from. one point of view the invention may be regarded as concerned with forcing the cleaning liquid against a limited area or zone of the work, while continuously withdrawing it from an immediately adjacent area or none, preferably by suction. Thus the cleaning liquid is continuousl forced into and drawn out ofthe work by a cleaning device readily moved progressively across the surface'of the work.
Another object of the invention is to provide a portable cleaning device in which the material to be cleaned is brushed or rubbed at the same time as it is treated with cleaning. liquid; According to one important feature the brush is moved by compressed air or the like which is also used to spray the cleaning liquid onto the material.
Various features of novelty relate to struction' and arrangement of the parts of the cleaning device, and particularly in the cooperative arrangement of two adjacent nozzles (one preierably extending part or all of the way around the other) through one of which atomized cleaning liquid is forced under fluid pressure against the work, and to the other of which suction is applied todraw the liquid away from the work after its cleaning action has taken place.
Still other features relate to the arrangement of a brush in the inner nozzle and to the provision of motor means in the nozzle for rotating the brush.
The above and other objects and features of. the invention will beapparent from the following description of the illustrative embodiment shown in the accompanying drawings, in which:
Figure 1 is a diagrammatic perspective view of the apparatus, the suction-producing device being shown in section; v
Figure 2 is a section through the portable device which is intended to be moved by the operator over the surface of the work;
Figure 3 is a side view of another portable device; and
Figures is an end view of the device of Figure 3. 65 posite the handle l2, toform attaching means for In the term illustrated in Figures 1 and 2, the
cleaning device includes a die-cast body l0, one
end of which extends downwardly nearly at a right angle to form a handle l2, and which has a suitable lug it for engagement by the operators fingers to facilitate grasping and manipulating the device.
-A passage It for fluid under pressure, usually compressed air, extends through the body in and handle 52 to a fitting l8 adapted for connection through a conduit 20, at least part of which is flexible, tea source of pressure fluid. The source the conillustra is the air tank 22 of an air compressor unit having a motor 28 driving a compressor it automatically controlled in the usual. manner to maintain a predetermined pressure in the tank 22. The passage i6 is under the control of a spring-closed air valve 28.
The body it of the device is also formed with a right angle passage 30 for cleaning liquid. This passage extends through a boss 32 to which is attached (with a ground joint to insure that no air leakage takes place), by means such as an attaching nut 34 threaded on the end of the boss 32, at an angle approximately paralleling the handle ii, a reservoir for cleaning liquid, such as one of the carbon tetrachloride group of noninflammable dry-cleaning liquids.
This reservoir includes a can-shaped body 35 adapted to be held in sealing engagement with a gasket $6 of rubber or other suitable material provided around the periphery 'of a cover 31. The
cover s1 has riveted or otherwise secured therein a boss as which forms the attaching means en- I gaged by the nut 36. The outer surface of said boss is formed with coarse threads engaged by a winged nut as which in turn engages a yoke it provided with a suitable central opening through which the boss projects. The yoke so has oppositely directed notches M, on downwardly turned endsthereoi which engage diametrically disposed pins d2 secured to the can-shaped body 35 and hold the body tightly against said gasket when the nut 33 is rotated in one direction, and loosely,
so as to permit removal'and refilling, when the nut St is rotated in the opposite direction. The
boss is formed with a passage opening into the passage at, and connecting toa conduit as secured to the boss and extending to the bottom of the can orbody 38.- This conduit is bent at such an angle that-it opens'from the side which is the lower side when the device is in use.
An internally and externally threaded ring 4 is shown threaded on the end-of the body w opa shouldered clamp ring 46 which attaches to the end of the body two annular members 48 and 56. The member 48 forms a conical outlet for the liquid passage 30, and cooperates with a needle valve formed on the end of a rod 62.
The member 56 cooperates with the member 46 to form an annular air chamber 54 communicating with the air passage I6 through an opening in member 46. The members 48 and 50 define between them; at the left, an annular air passage or nozzle surrounding the end of the liquid outlet, whereby the air issuing under pressure atomizes and entrains the cleaning liquid and projects it against the work being cleaned.
The needle valve rod 52 has its end slidably seated in a plug 56 threaded into the handle I2, at one side of the passage I6 therein, and is provided with a collar 58, a valve-closing spring 60 being sleeved on the rod and compressed between the plug 56 and the collar 56. Both of the valves 28 and 62 are adapted to be opened by pressure on a lover or trigger 62 pivoted on the body II).
The spray of air and cleaning liquid formed when the trigger 62 is pulled toward the handle I2 is directed against the surface of the work by a flaring elongated mouth or pressure nozzle 64, shown as diecast in one piece with an encircling wall 66 forming an annular suction mouth or nozzle 68 surrounding the pressure nozzle.
The wall 66 preferably projects slightly beyond the nozzle 64, to insure a good peripheral seal when the device is pressed against the surface of the work, as for example'the upholstery of an automobile. The wall 66 projects far enough to sink into the upholstery to give an effective seal Y when then'ozzle 64 is brought into engagement with the surface of the work. The casting 64-66 is attached to the cleaning device body III by means such as a clamp nut I6 engaging the ring 44. If desired it may also have secured thereto a stamping I2 formed with an opening sleeved on the boss 32;
The casting 64-66 is shown extended at one side, at right angles to the handle I2, to form an outlet I4 for the suction nozzle 68. The outlet 14 is thus conveniently arranged to serve as a second handle adapted to be grasped by the left hand of an operator'whose right hand grasps the handle I2.
The outlet 14 has attached thereto a flexible conduit ,16 leading to a portable suction unit.
This unit is inclosed in a casing 66 mounted on a; base 82, which may if casters 64.
The unit is-provided, within this casing, with a motor 66 driving a centrifugal pump or fan having an impeller directly driven by the desired be supported on into the surface of the work whence, after discleaning action will then be sucked from the,
motor 66 andarranged in a housing 66. The intake at the axis of the housing 66 is connected to the conduit 16. The-outlet of the housing 66 is preferably in the form of an exhaust pipe 62 having secured thereto a flexible conduit 64 adapted to be projected out of doors below or through an opening in the sash 96 of a window in the wall 66 of the building in which the device is being used.
The motor 66 may be connected by a cord I66 to a base plug I62, and may be turned-on and off by a suitable switch I 64.
It will be seen that, with the motor 66 turned on the device can be moved back and forth in engagement with the work, the valves 2: and 62 being held open by the trigger 62. This causes the cleaning liquid to be atomized and sprayed solving out grease spots and the like, it is continuously removed by the suction of the suction nozzle 68. Preferably the device is moved back and forth over the work a short time after the valves 28 and 52 are permitted to close, to leave as little of the cleaning liquid odor as possible.
Figures 3 and 4 illustrate an alternative con-' struction in which parts .corresponding to like parts in Figures 1 and 2 are designated 'by the same reference numerals plus I00. In this construction the cleaning liquid is supplied from a remote source through a hose or conduit I43 instead of from a container portable with the device. While the valve mechanism has not been shown in detail, it may be substantially similar to that of Figure 2.
A brush is mounted in the device to brush or scrub the material as it is cleaned and as shown includes a rod I63 rotatably mounted in' the nozzle and having on or more rows of bristles I66 thereon. The rod extends across the nozzle I64 adjacent one edge thereof and the bristles I65 are of such a length as to extend slightly beyond the front plane of the nozzle as seen in Figure 3.
In order to rotate the brush, the nozzle I66 is formed at its ends with integrally cast walls I 61 forming chambers I69 into which the ends of the rod I63 extend. The rod carries turbine wheels III in these chambers which are driven by compressed air conducted into the chambers by conduits I13 which extend into the chambers and terminate in nozzles I16 adjacent the turbine wheels. The conduits I13 preferably communicate with the compressed air passageposterior to the control valve so that the brush will be rotated when air is supplied to the spray but not otherwise.
The device of Figures 3 and 4 is used in sub- 4 and the material will be scrubbed or brushed while wet by the rotating brush. The cleaning liquid and any dirt particles loosened by the material through the outer nozzle I66.
While two embodiments of our invention have been described in detail, it is not our intention to limit its scope to thoseparticular embodiments, or otherwis than by the terms of the appended claims.
