Claims. (01. 15166) This invention relates to brushes adapted parity, as well as the bristles, receiving a charge ticularly for the formation or painting of letters of marking medium when the brush is dipped or characters as for example in the drawing or therein, the marking capacity of the brush being painting of price or display cards in stores or thus materially increased for each dip into the 5 other establishments. marking medium. 5

This grip sleeve could be the brush, this being accomplished by providing of plastic or molded material and provided with a recess or space in the body of the guide element a recess l3 opposite the flatted or indented part and communicating with the spaces or slits be- It of the ferrule in order to form a pocket into ,tween the comb teeth, these spaces and the cavwhich the guide element could be accurately in- 5.

sorted, as shown in Figure 6. The inner end of the guide element body is preferably tapered so as to facilitate its insertion between the grip sleeve and the ferrule.

5 The guide element could be of metal, but is preferably of softer material such as hard rubber, Celluloid, or plastic. The setting of the guide element is such that its end or guiding edge E will be in line with the ends of the bristles or just a slight distance behind the bristle ends. When the brush is dipped into ink or other marking material, the bristles and the slits M of the guide element will be charged with marking material, capillary attraction causing the bristles to spread at their ends for full width engagement with the end of the comb so that when the brush is now drawn along the surface to be marked, the edge E of the guide element will engage the surface to support the brush and take up the pressure while the bristles will apply the marking medium to the surface, the width of the line or stripe being determined by the width of the comb end of the guide element so that the lines or stripes will be of uniform width throughout if the edge E of the guide element is kept at right angles to the direction of the line or stripe. If narrower lines are desired, the brush is turned to angle the edge E relative to the direction of marking, and as the comb end is flexible laterally, waving lines gmcan be readily made, all under accurate guidance of the guide element. The brush structure may be thus easily manipulated by unskilled persons for accurate and uniform lettering or other markings.

a The comb end of the guide element, acting as a reservoir for marking medium to be fed to the bristles, materially increases the marking capacity of the brush structure for each dip into the marking medium. In order to further increase m the marking capacity per dip, the guide element 'may be provided with a cavity or recess IS in its under side with the recess located to communicate with the inner ends of the slits I4 so that when the brush is dipped in the marking medium, the

cavity will be filled and the contents gradually fed to the comb slits and to the bristles as the brush is manipulated.

'The comparatively slender teeth I5 will permit enough spring action to follow the brush over my1 rough surfaces so that the brush may apply marking material to fully cover the rough surface for unbroken lines of uniform width.

The brush structure can be easily used for ruling lines, as the guide element will form a guide 55 abutment for engagement with a ruler edge, and the ruler may be laid flat on the surface to be marked instead of being held up above the surface as would be necessary if the ordinary brush were used. The brush with the guide element 0 thereon could also be attached to a compass structure to make true and even lines, which would be almost an impossibility with the ordinary brush.

The guide element also serves to take the 55 Weight off of the bristles and prevent distortion thereof when the brush is stood in water to keep the bristles soft after a period of use of the brush. If it is desired to use the brush in the ordinary manner, the guide element may be read- 70 ily withdrawn, and as readily re-applied when its use is desired.

I have shown and described a practical and efficient embodiment of the features of my invention, but I do not desire to be limited to the exact "(Q-construction and arrangement shown and described, as changes and modifications may be made without departing from the scope of the invention.

I claim:

1. A guide element for cooperation with a soft bristle lettering brush and comprising a body part adapted for mounting on the brush handle and an outer part for overlying the brush bristles, said outer part terminating in a straight contact edge and being slitted longitudinally inwardly 7 from said edge to leave a row of teeth, said slits serving as reservoirs for marking fluid to be fed to the bristles and said edge being adapted to engage with the surface to be marked to guide the movement of the bristle ends over said surface and to determine the width of the line marked by the bristle.

2. A guide element for cooperation with a soft bristle lettering brush and comprising a body part adapted for mounting on the brush handle and an outer part for overlying the brush bristles, said outer part terminating in a straight contact edge and being slitted longitudinally inwardly from said edge to leave a row of teeth, said slits serving as reservoirs for marking fluid to be fed to the bristles and said edge being adapted to engage with the surface to be markedto guide the movement of the bristle ends over said surface and to determine the width of the line marked by the bristles, said guide element body having a recess therein communicating with the inner ends of said slits and arranged to receive marking fluid when the brush is dipped and to feed the fluid through the slits for delivery to the brush bristles.

3. The combination with a lettering brush comprising a holder and soft bristles extending from one end thereof, of a guide element comprising a body part and an outer part slitted longitudinally toprovide a row of comb teeth, a sleeve on the end of said holder serving as a grip and as a means for engaging the guide element body to secure it to the holder with its comb end overlying and in contact with the bristles and with the teeth ends substantially parallelling the bristle ends whereby when said brush is used the teeth ends will engage the surface to be marked and will define the width of the marking by the bristles, said teeth being flexible laterally but comparatively inflexible vertically.

4. A guide attachment for a soft bristle lettering brush in the form of a comb structure adapted to be mounted by its body on the brush holder with its comb teeth overlying and in contact with the brush bristles for engagement of the teeth end with the surface to be marked and to determine the width of the line marked by the bristles, said teeth being flexible laterally but comparatively stiff vertically.

5. The combination with a lettering brush comprising a holder and soft bristles extending from one end thereof, of a guide element comprising a body part and an outer part slitted longitudinally to provide a row of comparatively fine comb teeth, an elastic sleeve on the end of said holder serving as a grip and as a means for receiving the body part of said guide element to secure said element to the holder with its comb teeth overlying and in contact with the bristles and with the tooth ends substantially paralleling the bristle ends whereby when said brush is used the teeth ends will engage the surface to be marked and will define the width of the marking by the bristles.
