LE, CONNECTICUT, ASSIGNOR OF TW'O- AND ABRAM W. OSBORNE, BOTH OF FOUNTAIN-BRUSH.
SPECIFICATION forming part of Letters Patent No. 371,899, dated October 18, 1887.
To all whom it may concern:
Be it known that 1, CHARLES H. OSBORNE, a citizen of the United States, residing at Forestville, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Fountain-Brushes, of which the following is a specification.
My invention relates to improvements in fountain-brushes; and the objects of my im- 13 provements are efflciency in operation, convenience in use, and economy of construction.
In the accompanying drawings, Figure l is a central longitudinal section, partly in elevation, of my brush complete. Fig. 2 is a de- 15 tached view of a different form of brush-head adapted for use with my improvement, and Fig. 3 is a transverse section thereof on line 00 a, Fig. 2.
All of the parts shown in Fig. 1, except the yoke a, are of a circular form in cross section, and therefore the single View is deemed sufficient.
A desiginates the handle, which is made hollow to form a reservoir, 13, and preferably 2 5 of glass, so that the user can readily see when the supply of fluid .blacking is exhausted.
C is the upper collar, screw-threaded on its interior for the reception of the threaded cap D.
E is thelower collar, alsointeriorly threaded for the insertion of the brush-head F. This particular forth of brush-head is adapted for use as a stencil-brush. When the handle A, having reservoir B, is made of glass, the collars G and E may be attached thereto in any ordinary manner of securing collars on glass,
as, for instance, by cement.
The cap D is provided with an inwardlyprojecting hub, at the lower end of which is formed a valve-seat for the valve b. The valve- 0 stem 0 projects outwardly through the hub of the cap and terminates in a suitable knob or push-button, d. A spiral spring, e, surrounds the valve-stem and exerts a constant pressure in a direction to close the valve. The yoke a is in the form of a strap extending down'from the hub to form abearing for the upper end ofthe connecting-rod f. The lower collar, E, is provided with a like hub, valve-seat, valve b,

latter of which the lower end of the connect- 5o ing-rod is secured. This connecting -rod is disconnected from the valve 1), so as to allow the respective springs of both valves to act independently and better hold the valves closed than could be the case if both valves were rigidly secured to said rod. The upper end of the rod f, however, comes close to the under side of the valve 1), so that it will be depressed in opening the said valve.
The brush-head F is provided with a central tube, g, which extends down into the middle of the bristles or fibers of the brushhead, as shown. The upper end of said tube extends upwardly and surrounds the valve 1).
In use therescrvoir will be supplied with a 6 blacking or marking fluid. WVhen it is de- Y sired to feed the same to the brush, it is only necessary to depress the push-button (1, thereby opening the valve 1) to let in air. The valve 1) striking on the upper end of the connectingrod f will, by its continued movement, also open the valve 1) to let the fluid flow to the brush-head. Releasing the push-button (1 will permit the springs to close both valves.
Instead of a brush-head with a central feed 7 5 a brush-head with a surface-feed may be desirable, especially for small brushes, as a marking-brush. Such a head is shown in Figs. 2 and 3, and it is adapted to be screwed into the same handle, as in Fig. 1. The lower end of its tube It is slotted longitudinally, as at 76, so as to let the fluid run from the tube down on the exterior of the brush fibers. I do not wish to confine myself to thedetails of construction, but illustrate and describe this brush-head, Figs. 2 and 3, as one form of a surface-feeding brush-head that may be used in connection with my fountain or reservoir.
I do not claim, broadly, a fountain-brush provided with an outlet -valve, as several brushes of this character are shown in the prior art; neither do I claim, broadly, an outlet and inlet valve.
I claim as my invention- 1. The herein-described fountain-brush having a fixed brush-head and a reservoir provided with outlet and inlet valves at the botvalve-stem 0', spring e, and knob d, into the tom and top adapted to move independently of said brush-head, and a connecting-rod bement, but with the rod disconnected from one 10 tween said valves, substantially as described, of said valves, whereby the respective springs and for the purpose specified. act independently upon said valves in holding 2.
