FOUNTAIN MARKING-BRUSH.

SPECFICATON forming part of .Letters Patent No. 469,990, dated March 1, 1892.

Application filed October 1, 1891.

.To @ZZ whom t may concern:

Be it known that I, HENRY SCOTT BREWING- ITON, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invent-c d certain new and useful `Improvements in Fountain Marking-Brushes, of whichthe following is aspecilication.

This invention relates to an improvement in fountain marking-brushes; and the object is to simplify the construction for governing the oW of fluid to the brush, at the same time rendering the same more eective and arranging for the feeding of the fluid into the center of the brush.

To this end the invention may be said to consist in the novel features of construction and combinations of parts hereinafter described and claimed.

The invention is illustrated in the accompanying drawings, in Which- Figure 1 represents an exterior View of the. device; Fig. 2, a longitudinal section with the parts adjusted to cut olf the fiow of fluid to the brush; Fig. 3, a similar section with the parts adjusted to permit the iiuid to flow into the brush; Fig. 4, an exterior view of the handle, and Fig. 5 a section of the cap.

The device comprises a tubular handle A, constituting the reservoir for fluid and provided at one end with a cap a and at the opposite end with an exterior screw-thread b,

beyond which is a straight plain portion c and a conical end d, closed at its extremity. The outlet from the hollow handleis through small lateral openings or ports ein the conical part of the end d, and in the present instance there are two of these ports on opposite sides. I provide a cap B, which has an internal thread b to take on the yexternal thread of the tubular handle,a straight plain portion c t0 correspond to the straight por'- tion cof the handle, and beyond this straight portion a conical seat d for the end d of the handle. The cap is tapered on its exterior and terminates in a small tubular endf. The brush C is fastened on a'tapering nozzle g, which screws into the said tubular end f and opens at its outer end into the middle of the brush and at its opposite endinto the center or base of the conical seat d. It-will be ob- Served that this nozzle forms the stock ofthe Serial No. 407,364. (No model.)

brush, and by constructing it as a separate piece from the cap B to screw into the same brushes of different kinds and sizes, buthaving a uniform stock or nozzle, may be fitted to said cap. The cap B is screwed onto the tube A by means of the threadsb b', and it will be seen that it can be turned'until the conical end d of said tube fitssuugly against the seat d of the said-cap, whensaid seat serves as a valve to close the ports e and confine the Huid. Now upon turningback the cap B the seat or valve d is moved away from the conical end d and the fluid tlows through the ports e, which are thus opened, and down the space formed between the said seat land the said conical end into the nozzle f, which conveys it into the center of the brush C. It will thus be observed that the threads b b not onlyA serve as a means of connection between the cap B and handle, but also as a means for governing and regulating the feed of the fluid, for by turning the said cap more or less a greater or less amount of iluid is fed to the brush. It will be seen that by this arrangement a very tne adjustment may be had, so that the desired amount of flow of the fluid may be exactly obtained. The interior plain straight portion c of the cap B is lined with packing .h `of suitable material, forming a bushing in which the straight plain portion c of the tubular handle A fits and is movable. The said bushing is of such a length that while the cap B is on the handle it will always close the space between said cap and handle, and thus prevent the fluid from working back through such space.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a fountain-brush, the combination of a tubular handle to contain the fluid, having external screw-threads at one end and a conical part beyond said threads, with lateral openings or ports leading out of the-interior of the tubular handle, a tubular cap screwing onto the end of the handle and having a conical seat for the conical part of the said handle, which seat serves as a valve to open and close the lateral ports or openings in the latter by the turning of the cap, and a brush on the end of the cap.

2. In a fountain brush, the combination of a tubular handle to contain the Huid, having external screw-threads at one end and a conical part beyond said threads, with lateral openings or ports leading ont of the interior of the tubular handle, a cap screwing.r onto the end of the handle and having a conical seat for the conical part of the handle, which seat serves as a valve to open and close the lateral ports or openings in thelatter by the turning ot the cap, a detachable nozzle screwing into the end of the cap, and a brush secured on said nozzle.

3. In a fountain-brush, the combination of a tubular handle to contain the Huid, having external screw-threads at one end, a plain straight portion beyond said threads, and a conical portion beyond said Straight portion,

with lateral ports or openings leading ont of the interior of the tubular handle, a tubular cap screwing' onto the end of lthe handle and having a plain straight portion to correspond to that of the handle, and a conical seat for the conical portion of the Said handle, which seat serves as a Valve to open and close the lateral ports in the latter by the turning of the cap, a packing onbnshingr between the plain straight portions of the cap and handle, and a brush on the end of the cap.

' In testimony whereof I aix, my signature in 3o the presence of two witnesses.

HENRY SCOTT BREWINGTON.
