islvnecfication of Letters Patent.
Patented. July 31, 1906.
-5 State of Illinois, have invented certain new and useful Improvements in Fountain- Brushes, of which the following is a' descriping rawings, forming a part of this specification, 1n which 'corresponding letters' of refertion reference being had to the accompanyence in the different figures indicatel like parts.
Heretofore fountain brushes having a chamber in the back for thepassage of liquid have been -made from india-rubber formed in a sin le piece. in this form has been attended with difficulties and increased cost, owing to the extra Y care and skill required in the work and the necessit for additional vulcanization.
The o ject of my invention is to overcome this ob'ection by constructing a brush of the class escribed having a two-part hollow back-with means for preventing leakage along the line of juncture of the connectedl parts when liquid is forced into the recess or chamber between them.
'To these ends my invention consists inthe combination of elementsl hereinafter more particularly described, and definitely pointed out in the claims.
VIn the drawings, Figure 1 is a perspective viewl of a fountain-brush embodying thefeatures of my invention. Fig. 2 is a transverse vertical sectional view thereof, taken yu on the line 2, Fig. l. Figs. 3 and 4 are 'li e views showing modified constructions; and Fig. 5 is a pers ectivc view, partly in section, showing a sti l further modification.
Referring to the drawings, e represents the outer or upper portion of the back of a founfrom any suitable material-such, for example, as metal or celluloid, but preferably from soft rubber. Said part is provided with a depending peripheral flange b and, by preference,` with the usual hand-strap c, both of which are preferably integral therewi th. The 'bottom or counterpart portion d of the twopart backis made of such length and width as 5 'to enable to fit within the flan' e l with'its i bettomiiushwith the iower'edgeo saidflange,
The molding of the devicev while an upwardl -eXtended flange e, Fig. 2, preferably tapere at its upperedge and made ,somewhat longer than the flange b, is formed upon the outer edge of the part d and is bent inwardly at the top, as shown, so that when the two partsforming the back are united the upper part of the flange e will bear against the inner face of the top o between the flange b and a rib f,'which is formed around the top parallel to the ange b.
Formed 'upon the therewith is a row of buttons having Shanks g of a length corres ondin substantially to the thickness of the flanc said buttons being provided with heads and adapted to enter correspondin buttonholes formed to receive them 1n the ange b. f
An induction-tube t is-formed upon the flange e and is extended outwardly for the purpose of communicating with a source of .water-su ply, while uponthe bottoni of the channels in which communicate in the usual way with the space or chamber lc between the parts a and d: When in use, the water asses under more or less pressure from the induction-tube t into the'distributin'g-chamthe openings in the teeth. The pressure thus press closelyagainst the adjacent flange of sure between the two and wholly preventing leakage upon the line upon which the parts forming the back rare joined.
integral w1th the inner flap, l do not Wish to be confined to this construction, nor even to the buttons at all, as it is Obvious that theJ parts forming the back may be attached to each other in various way-s.
In Fig. 3 I have shown an inner flange l in addition to theouter flange b, with a'flange m upon the part d extendmg between`the two depending flanges, the threebeing coninserted through suitable perforations.
fn Fig. #i the part a is shown with an outwardly beneath .the 4bottom of the art d,
whiiethe flange ,p on the latter is made t cker,
flange e and integral ber lc, from whence it is discharged through nected by means of two headed fasteners n,
.ward flange o, extending downwardly and inpart d is ormed a series of hollow teeth y', the
- formed causesthe flexible flange or Hap e to the part a, thereby vmaking a complete clo- While l prefer to form the buttons upon and rco with vertical holes for the reception of the fasteners g. An inner lange r serves to close the joint.
In Fig. 5 I have shown a construction in which meeting flanges s t are provided with lateral extensions u v, which are sewed or laced'together by means of thread or twine tion-openin s z between them.
Among .t e advantages of my improved construction is the fact that the two parts constituting the -brush may be molded from india-rubber in the usual Way without extra vulcanization or fluid-pressure. -Moreover, the back proper maybe made from a diii`erent material ornamented in any desired way. The brush part can also be removed and replaced with a new one at any time ata saving of expense to the user. The fasteners while servin to detachably connect the parts may be use as ornamental features, being formed in any desired shapeor color.
Having ,thus described rnyinvention, I claiml. A device of the class described, in which is combined a back consisting of two parts detachably secured to each other with a chamber between for thev passage oi liquid, said lparts havin a marginal joint closed against leakage Iiy means o 'f an interior iiexible flap, and means for securing said parts together.
2. A fountain-brush in which is combined a back `formed in two parts separable from each other, with a chamber between, one of said parts having an interior flexible ilap adapted to press a ainst the other part t revent leakage at the connecting-joint when iquid is introduced into. said chamber, and
means for introducing li uid to said chamber and for discharging 1t rom the brush side thereof..
3. A brush ofthe class described, having a body formed in two parts from exible material with a space between the two, means for detachably connecting said arts, means for introducing liquid to said) space and means for discharging it upon the brush side thereof.
4. The combination in a brush of the class described, of a back formed in two parts with a chamber between, means for introducing l-iquid thereto and discharging it therefrom upon the brush side, oppositelyextended counterpart flanges, one upon each part, and means for detachably connecting sai anges.
5. A brush of the class described having a two-part hollow back for the reception of liquid, one part having a depending marginal flange and the' other a counterpart flexible flange fitted to extend loosely within said depending flange, and buttonsformedu n said inner iiange to engage openings in sa1d outer flange, whereby a tight 'oint may be formed when pressure is applied to the inner-flange 6. The combination in a brush of' the class described, of a back formed in two parts, from flexible material, with a space between the two, means upon the outer'edge or periphery of said parts for detachably connecting them, hollow iexible teeth upon one of saldparts, said teeth being open at their outer ends with their channels 1n communi? cation with said space, and means for introducing liquid to said space.
In testimony whereof I have signed this specification, in the presence of two subscribing witnesses, this 23d day of November, 1904.
