FOUNTAIN BRUSH.

Application mea my 15,- 1e24. ,semi No. 726,174.

To all lwhom it may concern; i v

Be it known that I, JQHN ERIK E RTKSON, a citizen of the United States, resldmg at South Bend, in the county of Pacific and State of Washington, have invented certain new and useful Improvements inFountarn Brushes, of which the following 1s a speellication. j

The present invention relates to a fountain brush intended for use as an ordinary paint brush as well as for oiling woodwork, floors and tools and ap lying polish to the bodies of automobiles. t will, of course, be understood that finer bristles should be used when oiling than when painting and that such a change can easily be made. j

The main object of the invention 1s to aint or the brush through the manipulation of a valve. The reservoir of the brush can very easily be relled by removing a cap at one end thereof and filling with oil or paint as required.'

In the accom anying drawing, one embodiment of the lnvention is illustrated, and Figure 1 represents a side elevation of the fountain brush;

Figure 2 is an axial Section thereof, and

Figure 3 is a transverse Section 'on the line 3--3 of Figure 2.

The brush has a cylindrical casing 10 which is intended to be closed by a cap 11 having threaded or other suitable engagement with the casing. This cap remains in position on the casing as long as the brush is in use and is removed only to fill the reservoir thereof. The other end of the casing is also closed by a cap 12 but which is intended to be removed whenever the brush is in use and serves only to protect the bristles when the brush is put away and to (prevent the drying up of the paint or oil hel in. This second ca the casing by threa s or in any other suitable manner.

The brush proper is constructed in the usual manner with bristles 13 firmly secured in a short ring 14 and in such a manner that a narrow passage or channel 15 is formed in the center of the brush. The ring 14 is threaded in an adaptor 16 which, in turn,is threaded at the lower end of the casing 10 and is screwed tightly therein. The ring 14 thereis held in position onv has an. outer flange 39 betweenwhich and the endof the adaptor 16 is inserted a gasket in order to provide a tight joint.

The hollow part of t-he casing constitutes a. reservoir 38 which is open at the top end and extends from the top edge of the casing to the bottom 17 of the adaptor 16. The arrangement is made so that a chamber 18 is formed between the bottom 17 and the top end of the brush bristles 13, as clearly shown in Figure 2. The bottom 17 has a central aperture 19 and around. the Same is placed a downwardly extending collar 20 forming a valve seat. Across the reservoir are provided three narrow arms or bridges 22, 23 and-24 arranged one above the other. These bridges are united with uprights 21 standing on the bottom 17 and reaching up to the top edge of the casing.` The two lower bridges, 22 and 23, form bearingsfor a plunger 25 which terminates about midway between the arm 23 and 24. This plunger is surrounded by a compression Spring 26 abutting with its upper end against a pin 27 which fits in an opening furnished across the spindle 25, as seen in Figure 2. In the lower end of the spindle 25 is threaded a shank 28 of a valve 29 between which and the seat formed by the collar 20 is inserted a gasket be obtained between the valve 29 and its seat 2O so that no leakage takes .places at this point.

A second spindle 31 is carried in the upper bearing 24 at one end and in a boss 32 formed on the inner side of the cap 11. A

ators finger. This spindle 31 projects only a short distance above the bottom of the recess 36 but does not project beyond the top face of the cap 11. This arrangement is made for the purpose of facilitating the standing in upright position of the fountain brush when not in use.

The reason what i i for dividing tlie-operatirig spindle into two parts 25 and 21 is to facilitate assembling and 'disassembling of the parts.

To fill the reservoir the cap 11 is first removed and the oil furnished or paint poured into the open end thereof until completely ornearly completely filling the reservoir. As the valve 29 is atthis time held tightly against its seat by the action of the spring 26 against the pin --27'invl the spindle 25, no leakage can take place even if the4 The' cap 11 is next screwed on tightly at the i brush is held with the bristles down.

upper end of the casing 10 so as to form a tight joint therewith. If the fountain brush is to be used immediately, the protecting cap 12 is next removed when the bristles 13 will be bared. By pressure on the visible end.

of the spindle 31, the latter is depressed `into the casing, thus .contacting with the upper end of the other spindle 25 and pressing the same downwardly'until the valve-29 opens. As the aperture 19 is of considerably larger diameter than the shank 28, thel oil or paint will then proceed through the aperture into the chamber 18 and meisten the bristles 13 of the brush when passing through the central passage 15 therein. .'l`heoperator may now apply the oil or paint. lVhenever the bristles begin to get dry, a slight pressure on the spindle 31 willfurnish a new supply of paint,v or oil to the same. When the4 operand auxiliary reservoirs, said adaptor having a central opening therethrough, and a Valve seat on itsl lower side around said \opening, a brush secured in the lower end of the adaptor, a disk valve adapted to rest against the valve seat in the adaptor and having a threaded stem extending through the opening in the adaptor, bearings in the main reservoir of the casing, a plunger mounted in some of said bearings and having its lower end engaged with the. threaded stern of the valve, a spring acting on the plunger to hold the valve normally seated, a cap closing the upper end of the casing, a second plunger mounted through said cap and in a bearing in the Acasing and disposed in alinement with the first-mentioned plunger, and a spring holding the last-mentioned plunger normally retracted from the firstmentioned plunger. f

In testimony whereof I afiix my si gnature.
