. fluidsupply from the fountain orreservoir to the brush under more perfect control, to pro- 10 vide means whereby the tube or fluid-duct will be kept from clogging, and to enable the operator. to adjust the length and density of the bristles to suit the work in hand; and it consists in combining with a reservoir for the rei 5 ception of a. marking or other fluid a tube leading therefrom to the brush, a valve closing said tube, a spring holding said valve normallyshut, and a diaphragm forming a portion of one side of the reservoir, and in proX- 2o imity to which the head of the valve-rod rests, whereby the valve may be opened by pressing said diaphragm, and at the same time the air within the reservoir compressed to expel a portion of its contents through the valve-open- 2 5 ing and tube into the brush; in combining withthe reservoir in a fountain-brush a tube leading from the reservoir to the brush, and a plunger passing through said tube, whereby it may be closed, and whereby, also, it will be cleared of all obstructions; in combining with the reservoir in a fountain-brush, and atube leading from said reservoir to the bristles or brush proper, a lateral inlet to said tube, and

a plunger fitting close within the tube and .35 playing therethrough past the'inlet to open or close the tube and to clear it from obstructions; and in the various other combinations and details of construction, hereinafter described and claimed.

4o For the purpose of fully illustrating the in- '45 cross-section of the foregoing to explain the clamping-band; Fig. 3, alongitudinal section of a stenciling or marking brush; Fig. 4, a side elevation of a shoe-brush with the reservoir in section, and Fig. an end view of a shoebrushin section through the reservoir and feed-brush.

A is the reservoir, prolonged into a handle and filled through a suitable aperture, a, with its screw-cap, and B the brush fixed to said reservoir at the proper end or in suitable rela- 5 5 tion thereto; 0, a tube rising into the reservoir and extending down into the brush, so as to discharge fluid from the reservoir into the body of said brush, that it may readily permeate the whole. .The fluid enters this tube through an opening, 0, which maybe at the end of thetube under certain conditions, but

is advisably at the side and just within the. wall of the reservoir, so that the contents of the latter may be entirely drained therefrom before refilling.

From near the inner end of the tube are offsets or ears 0, in which is pivoted a valve-lever, D, carrying at one end a valve, of leather, rubber, cork, or even of neatly-fitted metal, to rest upon or enter into the valve-seat formed in connection with the induction opening through the tube. At the other end of the valve-1ever is pin-jointed a rod, d, which passes through and is steadied by abridge, d, 7 5 supported from the walls of the reservoir, and terminates in a head, (1 intended to be covered with leather or other soft material, for wear.

A coiled spring, (2, encircles the rod between the bridge and its head, and tends to force it constantly in a direction calculated to closethe valve and keep it closed. That portion of the reservoir in which the end of the rod plays between the bridge and head is set 8 5 off slightly from the remainder, and is made, if possible, cylindrical, and formed with external screw-threads, so that a cap or diaphragm, E, may be fitted thereon and adjusted until its flexible diaphragm rests upon the go head of the rod or close thereto without interfering with the fit of the valve in its seat. WVhen this diaphragm is pressed the valve-1e ver will be moved, opening thevalve, and permitting fluidto enter the apertureinthe tube, 9 5 and the air in the reservoir will at the same time be slightly compressed, aiding in the flow therefrom. When, however, it is released, it will spring back to place, and the valve will be restored to its seat by the action of the coiledspring.

The construction thus far described is suffi- V cientfor beneficial results. I prefer, however, in order to clear the tube of any obstructions caused by the drying or clogging of paint or 1 is an unbroken ,rim or ring, G, flaring inother fluid therein, and also to guard against loss of contents from the reservoir when the valve is unintentionally opened, or is. out of order, to arrange a plunger, F, to slide horizontall y through the tube, fitting closely therein, and permitted, by means of a stop, f, striking against the wall 'of the reservoir or other suitable barrier, to be withdrawnonly just sufficient to clear the eduction-aperture. At the point where it passes out of the reservoir it will be led through a stuffing-box, F, composed of a screw-stud and screw-cap, receiving packing between them; or else composed of a cork set into the wall of the reservoir, or formed in any other suitable and efficient manner. At its extreme end it has a handle, whereby it may be operated.

Now, by working the plunger up and down it'is evident the tube will be kept clear, and that as long as it is down, past the eductionaperture, no flow will take place, whether the valve is open or closed. In order to operate the brush, therefore, the plunger must first be withdrawn as far as it will go, opening the apa erture, and the diaphragm then depressed to open the valve; and to shut off the flow the diaphragm will simply be released, and the plunger, if the brush is still in use, may remain open, allowing fluid to be turned on from time to'time while the work is in progress, by simply manipulating the valve. \Vhen the work is completed and the valve finally closed and the brush to be laid aside, the plunger will of course be driven home, to eject any sediment and to clean the tube and guard against accidental loss of contents. This plunger alone, in connection with the tube and its lateral aperture, may be used to allow and intermit the supply from the reservoir, the valve being dispensed with. This, however will give aless perfect command over the brush than if the two are used together.

Some kinds of work demand a stiff brush, and others a soft brush. If the bristles are long, the brush will be much more flexible or soft than if they are short. It it not desirable to keep a separate brush for every different kind of work, nor to trim down a brush once purchased to fit it for the first job in hand,

spoiling it thereby for some subsequent job.-

I propose, therefore, to apply to the brush an adjustable rim which may be set out toward the ends of the bristles, or brought in nearer their base. One form of such rim is shown in connection with the paint-brush. It consists of a band, G, of flexible metal, having at each end a lug, 9, through which lugs passes a screw-bolt, g, whereby its ends may be drawn together orlet out, as desired. This band should be just sufficient to encircle .the brush, and being applied to the bristles near their base, it may be loosened and moved out toward their ends and again clamped, thus making the effective length of thebristles anything desired. Another form which is appropriate for stenciling brushes and for shoe-brushes wardly, to embrace the bristles, and at its base made cylindrical, so as to slideupon a cylin-' drical block in which said bristles are held, or upon the cylindrical end of the reservoir. This can be slipped in and out along the bristles,-

and with the same effect, though not perhaps to the same degree, as if the band and screw were used.

In paint-brushes, the handle, although for greater capacity forming a part of the reserline with the exception of the offset to receive the diaphragm.

In shoe-brushes the preferable construction is as follows: The body of the reservoir is a cylinder set transversely to the wooden block H, which receives the bristles of the polishingbrush. The handle A is set in the side of the cylinder at right angles to its axis, and slightly oblique to its diameter at the point of attachment. The plunger runs through the axis of this cylinder, and its handle projects at one end,while the feed-brush is at'the other, projecting over the side of the polishing-brush beneath. The valve-rod rises vertically, and the offset receiving the diaphragm. is upon the top of the cylinder, where the diaphragm can be pressed by the forefinger as the handle is held in the grasp. A removable cap is employed,also,- to cover the bristles and prevent them from drying and caking, a frequent de-- fect in shoe-brushes.

I claim as my invention 1. The combination, substantially as here= inbefore set forth, in a fountain-brush, of a reservoir, a brush, a tube leading from the reservoir into the body of the brush, and having a lateral opening inside the reservoir close to the wall thereof, a valve closing said lat eral opening, a valve-rod, and spring to hold said valve closed, and a diaphragm above the end of the valve-rod and exposed externally, so that it may be depressed to open the valve.

2. The combination, substantially as hereinbefore set forth, in a fountain-brush, of a reservoir, a tube leading from said reservoir into the body of the brush, and having a lateral aperture inside the reservoir, and a clearingplunger playing through said tube and opening or closing the lateral aperture therein.

3. The combination, substantially as hereinbefore set forth, in a fountain-brush, of a reservoir, a brush, a tube leading from the reservoir into the brush, and havingalateral opening, aclearing-plunger playing through said tube, and a valve closing the lateral'opening.

4. The combination, substantially as hereinbefore set forth, in a fountaimbrush, of a reservoir, a brush, a tube leading from the reservoir into the brush, a plunger playing through said tube, a valve and valve-lever to close said aperture, a valve-rod, and spring, and a dia' phragm bearing upon the head of the valverod. i i a 5. The combination, substantially as herein- 5 before setfort'h, in a fountain-brush, of a reservoir, a brush, a tube leading from the reservoir into the brush, and having alateral opening, a plunger working through said tube, a valve closing the aperture, a valve-lever to operate the valve, a valverod pin-jointed to the end of said lever and guided by abridge, a coiled spring holding the valve closed, and an adjustable diaphragm that may be set against or in close proximity to the head of 15 the valve-rod when thevalve-rod is closed, whereby, when said diaphragm is depressed, the valve will be opened. a

6. The combination, substantially as hereinbefore set forth, in a reservoir shoe-brush, of a 2'0 the polishing-brush, the cylindrical reservoir set transversely to the body of said brush, the

7 o handle at right angles to the axis of said cylinder, the feed-brush at one end of the cylinder, the tube communicating with said feedbrush, the plunger playing through thetube from the other end of the cylinder, the valve and valve-rod, and the diaphragm at the top of the cylinder.
