Abstract: <PICT:0349106/III/1> <PICT:0349106/III/2> <PICT:0349106/III/3> A striping device for automobile bodies &c. comprises a reservoir and an applicator in communication therewith having spaced parallel ribs, the applicator being mounted so as to be freely rotatable, relative to the reservoir, about its longitudinal axis during travel over the surface to be striped.  In a construction shown in Figs. 1 and 2 a reservoir 10 contains the striping fluid, such as paint.  Paint is supplied to the reservoir by a pipe 14 through an adjustable valve 15.  A metal <PICT:0349106/III/4> tube 20 is disposed adjacent the wall 10a, in the interior of the reservoir, and contains a worm conveyer 24, which is rotated by the travel of the friction roller 32 along the surface under treatment, through the gear wheels 29, 30.  A port 22 is provided at the top of the tube 20 and paint enters the tube from the reservoir by a port 23.  The applicator comprises two ribs 36, 38; nib 36 being integral with the applicator body 35.  Nib 38 is slidable longitudinally within a socket against the action of a spring 39 and is guided by a pin 41.  A pen-supporting member 81 is detachably secured to a boss 80 by pins 82 projecting through aligned holes in the ports.  Pins 82 are secured to a lever 43, pivoted at 44, and provided with a thumb-piece 45, which may be pressed down by the operator against the action of a spring 49, thus releasing the applicator from the reservoir.  The member 81 has an annular groove to receive ball bearings 83 housed by a ring 84 secured to the applicator body 35, whereby the nibs are free to rotate longitudinally.  A guide support 55 is secured to the side of the reservoir, and on it slides a sleeve 56 carrying a guide-bar 57 drilled to form a socket slidably receiving the shank 59 of a guide 61.  A spring 60 and clamping screw 58 are provided. The nibs are able to conform to curves, beadings, &c. on the automobile body.  A modified construction is shown in Figs. 6 and 7.  A body portion 110 has a reservoir 111, provided with a closure 112.  A handle 114, threaded nipples 115, 116 and an extension 117 are provided on the body.  An apertured partition 111a allows fluid to pass from the reservoir to the body portion. Threaded on the nipple 115 is an applicator comprising a fixed portion 118 and a rotatable portion 119, these parts being held together by a ring 120 and being relatively rotatable through ball bearings 121.  Pivoted nibs 122, 123 are preferably hinged at 123a, to the portion 119.  A feed tube 124 extends towards the nib tips, and a clamp and screw 125, 126 allows adjustment of the nibs to each other and to the feed tube.  A needle valve 129 seats on the inner end of the feed tube 124, and its stem 130 carries fixed stops 131, 132.  A spring 134 bears against the stop 132 and the inner bore of an adjusting screw 133 threaded in the extension 117.  A cap 127 and packing 128 surround the valve stem through the nipple 116.  An operating lever 135, pivoted at 136, when pressed at the thumb-piece 138, forces the stop 131 and hence the valve stem 130 against the action of the spring 134, thus unseating the valve and allowing fluid to flow to the applicator. The device may be guided, as along a moulding M, by an adjustable and yieldable guide.  A pair of rods 155, connected at one end by a bar 157, carry a socket member 158 by means of lugs 160, 161.  A guide ring 164, bearing against the surface is connected to a bar 163 which is slidable in the member 158 against a spring.  A clamping screw 166 is provided.  The guide rotates with the nibs and hence will conform to curves or corners.
