Y Y Beit known that I, Cnnisrornnn A.v Grin- VEY, va. citizen of theUnitedStates of America, `landfaV resident of" tliefeoiinty of` St. Louis, State' ef Missonrnliave invented eer'- k A, tainl new andus'efiil Improvements inloiin tain-Brushes, Off which :the followi'i'igv is i a full clear and exactfde'scriotion "r ference 1 7 l Y i being Shad' to the 'jacc'onipanyingl drawings, forminga partA of'jthisspecieation. 'l My .invention relates to improvements in i "fountain-brishes, the main object -beingfto produce a siniple, `,inexi'iensive and very efficient niarking'brush, or stencil brush. j jj Prior to this invention stencil brushes and marking brushes have been provided lwith valvesfor controlling tlieflow' of ink tfoftlie brush tips-,fand Vit has been quite difir` cult to preventleakagel 'attlie valves'. The

ink is ,usually a tliin fluid, veryv difficult 4'to' co'nne intlieink reservoir, so tliat'a liigh `degree of,V accnracy has been required yin forming" the valves andvalve seats. Moreover, su'cli valves and Vtheir seats Aarey eX- pensive", liable to Vget out'fof order, andthe ,valvesfinustbe operated in laccordance with Y the judgment lof, the operator. to-fperinitthe j* Vmodification.

end to the lower end, and lateral bores 14 which communicate lwith said longitudinal channel, said bores 13 and 14 serving as channels for the iiow of ink therethrough, said wick being closely fitted to the inner faceof the tube C. The wick preferably is in contactwith the ink in the'reservoir and extends to a point beyond the lower end of the tuberi), the extended lower portion of the wick constituting a marking device; |The wick is preferably made of absorbent material, .and the tube C is preferably extended beyond the packing chamber to reinforce tlie'pliable lower portion of'saidwick.

`When` the device is in' service the lower end of the wick engages the article to be ymarked or lettered, and the pressure onthe wick tends r to-v force it backwardly, toward the reservoir.' However, a movement of this kind is positively prevented by the prongs '4 which extend into the wick, said prongs sorbent material in the packing chamber.

The saturated wick also tends to prevent liquid Yfrom flowing through the tube C.

- However, when the brush is in service the ink is wiped from the lower end of the wick, and the ink is constantly iiowing to compensate .for the displacement at this point.

Since the iiow is retarded by the absorbent material surrounding the ports in tube C, and also to a considerable extent by the wick itself, the flow of ink-isnot rapid, just suiiicient to keep the wick saturated at the point whereit engages the article to be `marked. l have found in practice that the tip of the wick is at all times more or less saturated, and `.when the.y brush is not in service it is laid horizontally on its side y and the ink willnot drip or flow from the lower portion of the wick. A slight 'jerk or throw of the brush immediately Yfurnishes an ample supply of ink to the marking tip, which may be repeated as often as may be *necessary/vY to retain an equal degree of saturation.

The stencil brush illustrated in Fig. V

comprises an ink reservoir A, a packing chamber B screwed onto the lower end of the reservoir, and a brush 10y detachably secured Vto the packing chamber. A discharge tube C is secured to the bottom wall of the packing-chamber, and a washer Gis placed on the upper end of the discharge tube to VLicense coniine the absorbent material 5 in the packing chamber. This absorbent material 5 is packed aroundl the tube to 'retard the flow of ink at the ports 3. An absorbent wick 8 is closely fitted tothe inner face of the tube C and secured by the prongs 4 which extend inwardly from the tube. i longitudinalchannel 13 Vextends from near the inner end of the wick 8" to'the end of said wick. 14 are transverse bores communicating with said longitudinal channel.

The ink passing from the reservoir to the brush 10, iiows onto the upper end of the wick, or around the washer 6 into the absorbent material 5 and then through ports 8 to the wick, and through the bores 14 to the channel 13y which furnish channels for conducting the ink to the lower end of the wick. The ink passing from the lower end of the wick flows through a tubev 12, forming part of the brush structure, and then along the bristles of the brush 10.

I claim: Y

1. 1n a fountain brush, a reservoir, a discharge tube for conducting liquid from said reservoir, a wick arranged within and closely iitted to-said discharge tube, said discharge tube being ported for the admission of liquid to the wick, and absorbent material fitted to the outer facey of said discharge tube so as to retard the flow of vliquid through the ported portion of said tube.

2. ln a fountain brush, a reservoir, a wick for conducting liquid from said reservoir, and a body of absorbent material whereby the flow of liquid from the reservoir to the vwick is retarded.v

4. In a fountain brush, a reservoir, a packing chamber for conducting liquid from said packing chamber, said wick being closely fitted to the inner face of said ported tube and extended therefrom to serve as a marking detachably` secured to the lower end ofsaid reservoir, a ported tube in said packing chamber, a wick i ivicknpholding tilbe surrounding and 'closelyf vvith'ai'*longitudinalrchanneliezrtendingfrom lo; .Y fitted' to said Wick, said YWick holding tube a vpoint!immediate one endithereof'through A being provided with ports for the admission said Wicl- Y, v of liquid to the Wick and'also' With prongs i 7.
