4 Claims.

This invention relates to the oflicialclass brushing and scrubbing and more particularly an automatic fountain swab and automatic liquid reservoir. a i

The primary; object of this invention resides pended" liquid reservoir.

in the provision ofafountain swab adapted to-be disposed in cooperative relation with a liquid reservoir so that it will be automatically filled when not in use and. be readily accessible. 7

Another object of this invention resides in the provision of an automatic fountain swab and automatic liquid reservoir adapted to be used separately or in conjunction with each other in the storing, dispensingfand applying liquids to other materials in such uses as sponging cloth;

in woollen mills; cleaning type in printing establishments; cleaning partsin garages; spreadswab disposed infilling relation with thesus- Fig. 2 is a detail perspective view of the supporting arm for the liquid reservoir. (Fig. 3 is an enlarged longitudinal sectional view through the swab and liquid reservoir disposed in. cooperative relation as shown in Fig. 1. Fig. 4 is a similar view of a portion of the swab taken approximately on line 4-4 of Fig. 3.

In the present illustration of this invention the numeral 5 designates a supportadapted to removably retain .a liquid reservoir 6 with which is removably associated a fountain swab l filled anyand all purposes to which it may be subjected.

therefrom and used for The support 5 comprises a suitably supported standard 8 provided with a liquid reservoir suping wax on floors or woodwork; and especially for the handling of solvents in the variousoperations connected with the preparation of stock j in the manufacture of tires,

tubes, and other rubber products. V .A further. object of this invention resides in the provision of a particularly constructed liquid reservoir adapted to be supported so as to cooperate with a particularly constructed founutain swab to permit automatic filling of the swab when not in use. i i

j 1 Aside from the aforesaid objects this invention resides in the particular construction of the swab. a x

In addition to the foregoing objects this invention resides in the particular means whereby liquid storedwithin the swab is supplied to the swabbing element, a

Among the many objects of this invention is the provision of means whereby the'reservoir of the swab. will be automatically opened when dis posed in filling relation with the liquid reservoir and closed when removed therefrom.

With these and other objects in view this invention resides in certain novel features of construction and arrangementofgelements to be hereinafter moreparticularly set forth in the specification, illustrated in the accompanying drawings and pointed out in the appended claims and, while this disclosure depicts my present'conception of the inventiomthe right is reserved to resort to such changes in constru'ctionand arrangement of elements as fall within the scope of the invention. 7 i a In the ac companying drawings forming a part of this invention: H

Fig. 1 is a side View of the automatic fountain porting. arm 9 at its upper end and an adjustable arm lll disposed thereon to retain the fountain swab in liquid filling relation with the liquid reservoir when not in use, said arm I0 is formed of resilient metal to permit connection and disconnection of the fountain swab with the liquid reservoir by simply pressing it downwardly how ever, it is within the purview of this invention to substitute other well known means therefor capable of carrying out tained.

The liquid reservoir 6 is provided with a removable Iair tight closure ll having a valvethe functions thus obstem l2 extending outwardly therefrom said valve-stem communicates with the interior of the liquid reservoir and is provided with a spring pressedoutlet valve [3 at its free end and an air vent-port l4 adjacent thereto in communication with a vent-tube I5 extending therefrom above the level of the liquid in the reservoir when inverted and in dispensing position. .In order to unseat the valve I3 and thus permit the liquid within thereservoir to flow therefrom, an I outwardly extending valve-stem l6 having a head w I1 is formed on the valve.

The swab l comprisesa hollow handle I8 having a partition l9 therein adjacent its open end toform afliquid reservoir 20. Disposed within the liquid reservoir 2|] and extending across the interior thereof is a sleeve 2| provided with apertures 22 and internal screw-threads 23 at its opposite ends to accommodate threaded plugs 24 and 25 adapted to tightly retain the sleeve within the liquid reservoir 20, the former of which is provided with a hole 26 adapted to receive the valve stem l2 of the liquid reservoir 6 while the latter of which is solid and acts as an abutment for an expansion coil spring 21 within the sleeve which causes a sliding valve 28 also within the sleeve to bear against the inner end of the plug 24 and close the hole therein when in normal or closing position of the reservoir 20.

Disposed in the partition l9 are spaced liquid exit ports 28 provided with spring outlet valves 29 having head valve-stems 30 extending therefrom toward the open end of the handle and ter minating against the inner wall 31 of head 32, pivoted as at 33 and carrying a suitable swabbing element 34, said wall 3| is preferably of convex configuration and is provided with apertures 35 to permit the liquid passing through the ports 28 to readily flow into the swabbing element.

With the liquid reservoir 6 and fountain swab I constructed as aforesaid, the valves-l3, 28 and 30 are normally held in closedipositions and,. upon inserting the valve stem [2 of the liquid reservoir 6 into the hole 26 of the plug 24,the

head I! of the valve-stem IE will contactand depress the valve 28 whereupon said valves'l3 and 28 will open and allow the liquid to flow from the reservoir 6 into the reservoir 20 until the level thereof closes the port M in the valve-stem thus stopping flow of the liquid with the valve l3 in open position.

Upon removing the swab "I from cooperative filling relation with the liquid reservoirfi the valve 28 will close under pressure of spring 21 and seal the opening 26 in the plug 24.

During operation of the swab over material to be treated the pivoted head 32 thereof will rock in the free end of the handle and cause the valves 29 to open whereupon the liquid within the handle will flow into the swabbing material through the apertures 35 in the convex wall of the head In order to obtain liquid from the reservoir 5 when the swab is detached therefrom it is simply necessary to press inwardly on the valve-stem l6 and the valve l3 will open. 7

While the swab 1 is herein shown as being cylindrical in cross section, it may be of any desired configuration capable of practicing the invention also the liquid reservoir 6 may be of any desired form and supported in any manner permitting the salient functions of the combination to be carried out.

With this invention fully set forth it is manifest that means are provided whereby cleaning of materials and analogous functions can be successfully performed quickly with the minimum degree of effort and, through the simplicity of the embodiment set forth, the cost of manufacture thereof will permit selling the same at a nominal price.

Having thus described my invention what I claim and desire to protect by Letters Patent is:

1. The combination of a liquid storage reserhas reached a predetermined level in the handle.

2. The combination of a liquid storage reservoir, a support therefor, a fountain swab having I its reservoir removably engaged with the storage reservoir, and means stopping the flow of liquid from the former into the latter while in filling relation by a predetermined level of liquid in the latter.

3. The combinationof a liquid storage reservoir including a valved discharge nozzle and air vent leading therefrom above the level of liquid therein, a fountain swab including a hollow handle and a spring closed inlet valve engaged and opened by the nozzle of the storage reservoir, a support carrying the storage reservoir, resilient means carried by the support and removably retaining the valves of the nozzle and handle in open positions when the handle is in filling relation with the storage reservoir and an apertured sleeve within the handle surrounding the valve thereof forming communications between the reservoir thereof and nozzle, the uppermost aperture being elongated and disposed in the region of the lower end of the vent in the nozzle.

l. A swab comprising a hollow handle, a partition in the handle adjacent its open end and having spaced ports therein, spring pressed outlet valves in the ports of the partition, an apertured dish-shaped head pivotally secured at diametric opposite points in the open end of the handle adjacent the valves, a swabbing element carried by the head, valve-stems formed on the valves and bearing on the inner dish-shaped wall of the pivoted head and a filling valve communicating with the interior of the handle.
