6 Claims. (Cl. 137-604) This invention relates to a cleansing or washing tool or instrument.
An object of the present invention is to provide a hand tool for cleansing purposes that optionally provides a supply of clear water, a solution of water and one ingredient such as soap or detergent, for instance, and a mixture of water and another ingredient such as a sterilizer, the invention contemplating a tool that is timesaving and highly eflicient for the intended purpose.
Another object of the invention is to provide a washing or cleansing tool of the character referred to that has its controls so arranged that only one solution or the other may be discharged at one time.
A further object of the invention is to provide a washing tool in which the controls may be manually manipulated to provide a sequential operation of first water alone, then one solution as above, and finally the other solution.
A still further object of the invention is to provide a tool that discharges two different solutions, sequentially, one for cleansing purposes and the other for sterilization.
The invention also has for its objects to provide such means that are positive in operation, convenient in use, easily installed in a working position and easily disconnected therefrom, economical of manufacture, relatively simple, and of general superiority and serviceability.
The invention also comprises novel details of construction and novel combinations and arrangements of parts, which will more fully appear in the course of the following description. However, the drawing merely shows and the following description merely describes, preferred embodiments of the present invention, which are given by way of illustration or example only.
In the drawing, like reference characters designate similar parts in the several views.
Fig. l is a broken longitudinal sectional view of a washing tool embodying features of the present invention.
Fig. 2 is a cross-sectional view as taken on line 2-2 of Fig. l. I
Figs. 3 and 4 are similar cross-sectional views showing the tool in different operative positions, Fig. 3 to discharge one solution and Fig. 4 another solution.
Fig. 5 is a broken plan View of a modification.
The instrument or tool that is illustrated comprises, generally, a housing 10, a normally-closed Water valve 11 located adjacent one end'of the housing, an inlet 12 to said valve 11, a handle 13 for controlling the valve, an inner body 14 adjacent the other end of the housing and receptive of flow from valve 11 when the latter is opened by manipulation of the handle 13, a valve 15 in the body 14 and an inlet 16 thereto for supplying a flow of one ingredient, such as a liquid detergent, to the interior of the body, a valve 17 in the body 14 and an inlet 13 thereto for supplying a flow of another ingredient, such as a liquid sterilizer, to the interior of the body, the handle 13 being extended to control the valves .15 and 17, and a discharge-passing extension 19 on the end of the housing 10 beyond the body 14 and provided Patented Mar. 21, 1961 ice The housing 10 is preferably formed as an elongated,
interiorly-hollow member of desired hand-gripping size and form. The details of its shape may vary providing the same is made to house the valve 11 and body 14 together with the connections and controls therefor. Said housing may be metal and is advantageously made of non-metallic or plastic material for good wear and heat insulation where needed. a
The valve 11 is shown as having a valve body 21, wholly or partly housed within housing 10, a valve disc 22 interiorly of said body 21 and normally biased to a closed position against a valve seat 23 formed in said body, an inlet port 24 and an outlet port 25. Structurally, said valve is generally conventional and, when its valve disc22 is displaced from its seat 23 against the bias of spring 26, flow is established from inlet 12 to a tube 27 extending from the outlet 25.
The inlet 12 preferably comprises a flexible hose 28 that, by means of a fitting 29, is connected to the valve inlet 24. Of course, the hose may be connected in the usual way to a source or supply of liquid, such as water. In practice, the inlet 12 preferably has central alignment with the housing 10, substantially as shown.
A valve stem 30 is guided. by the valve body 21 in impinging relationship with the valve disc 22 and extends outwardly of the housing, preferably radially. The handle 13 comprises a lever 31 mounted on a hinge pin 32 mounted between support ears 33 that extend from the valve housing 21 through the housing 10. Said lever 31 extends lengthwise of and above the housing and in operative engagement with the stem 30. It will be evident that manual depression of the lever against the'bias of a leaf spring 34 causes depresison of said stem and opening of the valve 11.
The inner body 14 is shownas in the form of a block 35 that is connected to the flow tube 27 and is provided with a longitudinally disposed Venturi passage 36 that receives the flow from said tube. The outlet end of passage 6 is provided with an air intake hole 37. A tubular extension 38 is provided for the Venturi passage beyond its discharge end.
The valve 15 comprises a spring-biased ball 39 that closes the end of a bushing 40 in a bore 41 in the body block 35. A stem 42 is guided in said bushing and extends outwardly of the housing 10. As can be seen, the valve 15 is disposed to one side of the throat portion of the Venturi passage 36 and the interior of the bushing is connected to said passage by a port 43. 'It will be noted that normally the valve is closed and the stem 42 is held by the ball 39 clear of the port 43. When closed, as in Fig. 2, said valve prevents flow from inlet 16 to the throat of Venturi 36. When the stem 42 is depressed by the handle lever 31, as in Fig. 3, the ball is unseated and flow from outlet 16 to the Venturi is established, the rate of flow being a function of the pressure drop or suction eflfect dependent upon amount and speed of flow of water through the venturi.
When the lever 31 is fully depressed, the barrel or wider portion of the stern 42'closes off the port'43, thereby closing the valve 15. Thus, upon operative movement of the lever, valve 15 is first opened by unseating the ball 39 and is then closed by the stern closing port 43, The latter position is shown in Fig. '4. The operator may be apprized of the movement of said valve from open to the closed position of Fig. 4 by any suitable means, such as a click device or other'momentary stop.
The details of construction of valve 17 are'substantially similar to those'of valve 15. The only change is in the length of the stem 42a, the same being shorter than stem 42. Valve 17 has only the closed position of Figs. 2 and 3, which is maintained during movement of the valve 15 from its normally closed to the open position of Fig. 3, and the open position of, Fig. 4 wherein the final operative movement of the handle 31 causes the stem 42a to unseat the ball39a to open flow from inlet 18 through a port 43a to the throat of Venturi-36. During the latter position of valve 17, the valve 15 is closed, as above described. Hence, only inlet 16 or inlet 18 is open, at any one time, to flow into Venturi 36 for admixture of the flow in said inlets to the flow in the Venturi.
Of course, when the handle 13 is released, both valves 15 and 17 close and remain closed until the handle is again depressed.
The modification of Fig. 5 will be provided with valves a and 17a that are normally closed but can be moved only to open position by the handle 13a. Said valves 15:: and 17a are alike except that the stems thereof are of unequal length so that one can open before the other opens. Said stems may be made of the same length if the handle is so formed as to contact and depress one stem before the other is contacted and depressed.
By providing a stop 44 that limits operative movement of the handle, the valve 15a may be opened without the valve 17a being opened. After flow for cleansing purposes is allowed to continue as desired, the handle 13a may be shifted laterally, as on a hinge 45, to lose contact with the stem of valve 15a, thus allowing said valve to close. This lateral shifting of the hnadle removes the same from engagement with the stop 44. Now, the handle may be further depressed to open valve 17a. A spring 46 returns the handle to its initial condition as the same is released to allow spring 34 to raise the handle, as before described.
The modification provides a construction that enables opening valve 17a without disturbing valve 15a, and vice versa.
Thus, the extension 19, in the form of a tube, receives flow that may be water alone or a solution of detergent or sterilizer, sequentially, or as desired. The change from one to the other flow is instantaneous, as controlled by movement of the handle.
The implement is shown as a brush, but the same may vary and, consequently, may be interchangeably connected to the housing 10 or the extension 19, as desired.
While the foregoing specification illustrates and describes what we now contemplate to be the best modes of carrying out our invention, the constructions are, of course, subject to modification without departing from the spirit and scope of our invention. Therefore, we do not desire to restrict the invention to the particular forms of construction illustrated and described, but desire to cover all modifications that may fall Within the scope of the appended claims.
Having thus described our invention, what we claim and desire to secure by Letters Patent is: a
