Application June 24, 1955, Serial No. 517,865 3 claims. (C1. 299-83) The object of the invention is to provide a lather dispenser using liquid soap, but provided with a manual means for aerating it and ejecting it, thereby avoiding the useof mechanical means, such as motors, with Atheir likelihood of impairment; to provide a device of the kind indicated in which the liquid soap is stored above the aerating chamber and admitted to the latherperiodically as depletion in the aerating chamber obtains; to provide a lather dispenser in which the aerating chamber is at a low level compared with the point of ejection of the lather, so that there may be no possibility of fluid soap following the lather in a dispensing operation; to provide, in a device of the kind stated, a heating means adjacent the aerating chamber and below the soap storage chamber, whereby the aerating chamber may be kept at a uniform temperature; to provide a hand pump serving the aerating chamber through a conductor which is so positioned that the likelihood of drawing soap into the pump is reduced to a minimum; to provide a strainer in the discharge means for the lather, so as to break up any hard particles in the same; to provide the discharge means in a form to be reversible in order that the screen, having become clogged at any time, may be reversed to be cleansed in a following ejecting operation; and generally, to provide a lather dispenser which is of simple form, composed of comparatively few parts, with the likelihood of failure at any time reduced to a minimum, and of such a character as to be susceptible of cheap manufacture and sale.
With this object in view, the invention consists in a construction and combination of parts of which a preferred embodiment is illustrated in the accompanying drawings, wherein:
Figure 1 is a vertical longitudinal sectional view of the invention;
Figure 2 is a sectional view on the plane indicated by the line 2-2 of Figure l;
Figure 3 is 'a sectional View on the plane indicated by the line 3-3 of Figure 1;
Figure 4 is a bottom plan view of the structure illustrated in Figure 1;
Figure 5 is a detail sectional view of the heater; and
Figure 6 is a sectional view through the vent valve.
Lather is dispensed from the aerating chamber 10, which is below the soap chamber 11, to the bottom wall of which the aerating chamber is tixedly attached as by welding or soldering as indicated at 12. In the bottom wall of the soap chamber (which is, of course, designed to contain liquid soap), is a valve 13, having a lateral inlet port 14, through which the soap enters the aerating chamber when the valve disc is raised, as it may be by means of rotating the stem 16 through the instrumentality of the handle 17, mounted on the upper end of the stem and secured in place thereon by the screw 18. The stem projects through an opening in the cover 19 which closes the soap chamber and which is removed to permit charging the lather with liquid soap. The cover carries a tubular guide 20, in
Patented Jan. 27, 1959 which is slidingly mounted a rod 21, provided at its upper end with a knob 22. This rod constitutes the operating means for the valve 23, which is normally heldin closed position by the compression spring 24, bearing one end upon the head 25 and the other end in the bottom of the case 26, which has lateral ports 27. The valve is mounted inthe upper end of a tube 28, which communicates lwith the'aerating chamber and, when the air pressure in the latter has reached a point where it may eject lather through the discharge support without operation of the pump, the excess air may be vvented oil into the soap chamber by the opening of the valve through the simple expedient of depressing the knob 22 of the rod 21, the lower end of which bears upon the head or member 25.
The lather is dispensed from the aerating chamber through a standpipe 29, which is xed at the bottom of the-soap chamber and communicates with the aerating chamber and which, at its upper end is provided with an elbow 30, in which a discharge nozzle 31 is threadingly-engaged, this nozzle being interiorly provided with a plurality of screens 32, set in the nozzle and separated by intervening spacers 33, in the form of rings. The nozzle is threaded at opposite ends so that if the screens become clogged, the nozzle may be reversed and the large particles, clogging the screens, ejected through the open end of the nozzle. The nozzle is formed with a shoulder portion 34, exteriorly knurled to provide for its being readily removed by hand and reversing position.
To provide for an aerating chamber at proper temperature, a heater 35 is employed, this heater being in the form of a porcelain-covered resistance, mounted on an insulating block 36, with the terminals led to binding posts 37, to which are connected the terminals of a flexible cord 38, by which the resistance may be electrically excited.
The aerating means consists of a pump in the form of a cylinder 39 closed at its lower end but vented, as indicated at 40, at its upper end, so that there will be comparatively no resistance to the upstroke of the piston 41, to which is connected a piston rod 42, terminally fitted with a hand knob 43. On the upstroke, air will pass down below the piston and when the latter is depressed, it will be ejected through the check valve 44 and through the hose 45 into the aerating chamber, into which it enters through the fitting 46, which is openended, but which is provided with a circumferential series of lateral ports 47, so as to disperse the air as it enters the aerating chamber. The check valve 44 is of a form to preclude entrance into the pump thereat', but to provide for discharge therefrom. All of the parts heretofore described are enclosed in a case 48, which is open at the bottom and also at the top, but only when the cover 19 is raised, which may be done by removing the handle 17 from the stem 16.
In the operation of the invention, the soap chamber 11 is charged with liquid soap, after which the valve 15 is opened to admit a supply to the aerating chamber 10. The valve 15 is then closed and, the resistance having been connected to an exciting source, the contents of the aerating chamber are heated and the device is ready for operation, the piston of the pump being raised by pulling up on the knob or handle 43. Then to start the ejection of lather, the piston is depressed, the operation continuing until the desired amount of lather has been ejected through the discharge nozzle 31. In use, each operation requires only part of the full piston movement, so that when the latter has once been raised, several periodic depressions of the piston rod take place before it must again be raised.
The tubular conductor connecting the pump with the fitting 46 is arranged in an upwardly forming curve so ermee as to preclude any possibility of soap finding its way into the pump, even though the check valve 44 might otherwise permit this condition in some instances.
Of course, there are times when the aeratng chamber will be over-charged withV air. Thaty condition can easily be corrected' by depression of the knob 22 to open the ventvalve 23=.
The invention having been described, what is claimed as new and useful is:
1. A lather dispenser comprising a soap chamber, an aerating chamber directly below the soap chamber and in valveci communication with the latter, a hand pump discharging air into the aerating chamber, a standpipe in the soap'chamber and communicating with the aerating chamber, a discharge nozzle connected with the standpipe, the nozzle level being well above the level of the aerating chamber, a vent valye positioned in the soap chamber but in communication with the aerating chamber, and an exterior operating means for the vent valve to relieve theaerating chamber of excess air.
2,. A lather dispenser comprising a soap container, an aerating container therebelow and in valved communication therewith, a lather discharging standpipe extending upwardly from said4 aerating container and provided with a discharge nozzle located above the liquid level of said soap container, and a pump in communication with said aerating container.
3. A lather dispenser comprising a soap container, an aerating container therebelow and in valved communication therewith, a lather discharging standpipe extending upwardly from said aerating container and provided with a discharge nozzle located above the liquid level of said soap container, and a pump in communication with said aerating container, the pump being7 adjacent to the soap container which extends laterally beyond the aerating container, so as to provide a space between the latter and the pump, and a heating resistance disposed in said space and operative to thermally alect the aerating container, the soap container and the pump.
