FRANK D. FARNAM, OF EDISON PARK, CHICAGO, ILLINOIS, ASSIGNOR TO FARNAM FOUNTAIN CLEANING BRUSH COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.
Specification of Letters Patent.
Application filed August '17, 1914, Serial No. 857,024. Renewed March 30, 1916. Serial No. 87,857.
To all whom it may concern:
Be it known that I, FRANK D. FARNAM, a citizen of the United States, and a resident of Edison Park, Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Cleaning Devices; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, andto the numerals of reference marked thereon, which form a part of this specification.
This invention relates to that class of cleaning devices set forth in my prior application for patent for Cleaning devices for utilizing volatile liquids, filed on the 15th day of November, 1912, Serial No. 731,591, and wherein a volatile cleaning fluid is discharged from a container by pressure generated therein by the volatilization of said liquid from the heat of the hand holding the container.
The object of this invention is to provide a device for dispensing a cleaning (or other) liquid therefrom in graduated amounts and as required for service, and to afford a construction adapted for use either for volatile or non-volatile liquids and so constructed as to permit the entire contents of the container to be discharged, as required, either through pressure generated by the expansion of the liquid or independently of such pressure, dcpendent upon the character of the liquid used.
It is also an object of the invention to afl'ord a construction adapted for use in connection with a device such as set forth in my aforesaid pending application for patent wherein the liquid may be discharged by pressure from the volatilization of the liquid or by atmospheric pressure, as required, thus enabling the entire contents of the container to be discharged at the rate required for use.
It is finally an object of the invention to afford a founta n brush, the discharge from the fount of which is occasioned wholly or in part from the heat of the hand or may be produced mechanically, as preferred.
The invention (in a preferred form) is illustrated" in the accompanying drawings and herein after more fully described.
In the drawings: Figure 1 is a side elevation of a device embodying my invention.
Fig. 2 is an enlarged, central fragmentary section thereof. Fig. 3 is a section on line 3-3 of Fig. 1. Fig. 4 is a reduced section on line 41 of Fig. 2. Fig. 5 is a reduced section on line 55 of Fig. 2. Fig. 6 is a reduced fragmentary detail section taken on line 66 of Fig. 5. i
As shown in the drawings: 1, indicates a container preferably of thin metal, having high thermal conductivity, for example, thin brass or copper, as shown cylindric in form (though not necessarily so) and having a head 2, provided with peripheral flange 3, which fits within the'lower or discharge end of the container and is permanently and rigidly secured therein to afford a tight joint and aflording a cavity or recess at the bottom of the device to receive the brush back 1, as shown in Fig. 2. Preferably, the end of the container and the flange 3, of said bottom head, are provided on opposite sides thereof with apertures to receive pins or dowels 5, therein, which extend therethrough and into the back of the brush at its periphery, as indicated in Figs. 2 and 4, to removably engage the brush in place. A spring clip 6, of any suitable metal, engages around the lower end of the container and covers the outer ends of said pins or dowels 5, and retains the same in place, but removal of the clip permits the dowels to be removed, thereby permitting the removal of the brush.
A flanged cover 7, tightly closes the upper end of the container and may be applied in place either with or without a gasket, as preferred, and the flange thereof, as shown in Fig. 1, is provided with lamp socket notches on opposite sides thereof to receive therein each a pin 8, set in the upper end of the container and set to extend outwardly from the periphery of the container, as shown in Fig. 1, whereby the cover or cap may be turned into rigid engagement to close the upper end of the container or may be quickly removed therefrom, as preferred.
As shown, an air inlet valve 9, of any preferred construction, may be provided at the inner side of the cap or cover 7 and the closure 10, therefor is supported by a weak spring 11, sufficient normally to hold the closure seated and preventing escape of the contents of the container against any internal pressure, but readily yielding to permit inflow of air at atmospheric pressure, venting the container therebyto permit discharge of the contents at the bottom. A discharge aperture and short pipe 12, are provided in the bottom head of thcontainer, as shown in Fig.2, to conduct the liquid through the back of the brush and to the hair (or other) brush material. secured thereon, and as shown, a bracket 1-3, is secured on the inner side of said bottom head and apertured in alincment with said-pipe 12, and extending therethrough is a valve stem 14, which, at its lower end, is provided with a tapered valve closure 15, affording substantially a needle valve. Abovesaid closure a collar or enlargement 16, is provided on the valve stem, and a spring 17 is secured on said stem and bears on the collar and said bracket and acts normally to hold the valve seated. Extending diametrically across said container near the top thereof, and secured to its side walls, is a bar 18, and pivotally' engaged thereon is a bent lever 19,
one arm of which extends above and parallel with said bar 18. and upon which engages the upperhooked end 20, of the valve stem 14. As shown in Fig. 2, a portion of the wall of the container is cut away, and a thin resilient plate 22 is secured thereto in any suitable manner to cover said cut away portion. The other end 21 of said lever 19 extends downwardly and laterally bearing at its free end against said plate 22. If preferred, of course, the wall or shell of the container may be made su'iiic'iently thin to be vieldable' and resilient, in which case the entire body portion of the container may be made in one piece.
The operation is as follows: The container is filled to a suflicient extent with the liquid to be dispensed therefrom, by removing the cover 7, to permit of pouring the liquid thereinto and the cover is then replaced, as shown in Fig. 2. A slight pressure is then brought to bear upon the weakened portion of the wall of the container,
pressing the arm 21, of the bent lever inwardly and thereby unseating the valve closure 15, and permitting the desired amount of the liquid content to be discharged to the brush through. the pipe 12. Such discharge in the case of volatile liquids, is materially assisted by the volatilization of a portion of the contents because of the heat of the hand in which the container is held. Immediately upon releasing the pressure upon the weakened portion of the wall, the
valve closes and no further escape of the contents can be eflected until the valve is again opened, as before described.
Obviously the arrangement of Valve is such that augmentation of pressure within the container, acts normally to hold the valve seated so that under any conditions,
when the device is not in use, there can be" no escape of the volatile liquids, for example, gasolene therefrom, and in consequence, dan-' ger of. firms obviated. After a considerable quantity. of the liquid has been dispensed from the container, and the level thereof" falls suificiently low, the volatiliZ'ati'on from the heat-of the hand, although present, is
much less in extent than when a greater quantity of gasolene or other volatile-liquid is in thecontainer, When the valve is open, therefore, atmospheric pressure assist insuring the discharge by the opening of the valve 10, and the resulting inflow of atmos pheric air. Of course, if desired, an auto= matically acting discharge valve may also be provided in the bottom head 9, of the de vice, so that the device'operates automatically from the heat generated by the hand,
asdescribed in my said co-pending application. lVhere this construction is used, the valve 15, need not be operated untll such time as the flow of the hydrqc'arb'On liquid v has practically ceased-*becau e of pressure gasolener maining in the container.
exhaustion, due to the small quantity yo Obviously, by the'construction described,
the discharge of the fluid is at all times in control of the operator, and the quantity to generate material or sutfi'cient pressure to assist in the discharge,the discharge may at all'times be effected and controlled by means of the actuation of the lever aforesaid through pressure exerted upon the weakened Wall 22 of the container, the liquid as discharged being replaced by atmospheric air being permitted to flow in through the valve 10'.
Of course, where non-volatile liquids" Of course, details of construction may be varied through a wi'derange and I therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.
I claim as my invention: A device of the class described, comprising a container, a peripherally flanged headin one end of said container, a brush fitted into the recess afforded in said head by said flange, said head having a passage there through for supplying fluid from said cone tainer to said brush, dowels disposed in registering a ertures in said container, flange and brushto retain said arts together, a spring clip on said container oversubscribed my name in the presence of two lying sald dowels removably to retaln them subsoribmg Witnesses. 1n position, a valve controlling the passage through said head, and lever mechanism FRANK DFARNAM' 5 Within said container operated by pressure Witnesses:
