314,200. Marks, E. C. R., (Packard Motor Car Co.). June 8, 1928. Coating - appliances, hand. - A lining-tool for applying a line or stripe of paint to a surface is provided with a roller which effects the positive feeding of the paint when moved over the surface to be lined, the feeding means being located between a container for the paint and an outlet nozzle. In one form, Figs. 2 and 3, the body 10 of the tool is substantially V-shaped, with a hollow handle 11 which serves as a paint container extending rearwardly therefrom. A vertical bore 25 leading from the handle is connected by a horizontal bore 24 to the lower end of a vertical passage 23 disposed at right angles to two parallel transverse bores 13, 14 which overlap one another and form housings for two intermeshing gear wheels 15, 16, the action being such that when the gear 16 is driven by running the tool along a surface the paint is fed into the upper end of the passage 23, along a passage 26, and out through the nozzle 43. The gear 15 is journaled on a shaft supported at the ends of the bore 13, the gear 16 being keyed upon a shaft 19 which is journaled in sleeve-bearings 20 and is provided at its ends with a guide roller 21 and guide spool 22 respectively. The nozzle is normally closed by a spring-pressed ball 45, Fig. 5, and is secured in a block 29 which is pivotally mounted upon a hollow shaft 28, a wire spring 35 being connected between the body 10 and a lug 34 on the block 29 to hold the end of the nozzle upon the surface being operated upon. Connection between the nozzle and the bore 26 in the body 10 is established by a circumferential groove 32 in the hollow shaft 28 registering with the bore 26 and conducting the paint through radial grooves 33 into the central bore 31 of the shaft, a similar arrangement of radial bores 42, Fig. 5, being provided to connect the other end of the bore 31 with the central bore 40 of the nozzle. In order that the feed of paint may be maintained, whether the tool be used upon a vertical or horizontal surface, an auxiliary paintcontainer may be mounted on either side of the body 10, at right-angles to the handle 11, by screwing it within a hole 47 which is normally closed by a screw 48. Both the handle and the auxiliary container have an end-cap 50 which is provided with a spring-loaded venting-valve 51 and is unscrewed in order that a supply of paint may be inserted therein. A follower 52 may be provided to bear upon the surface of the paint to increase the rate of flow. The forward edge of the end of the nozzle is preferably chamfered, as shown in Fig. 27, so that when the tool is drawn over a surface and the nozzle thereby inclined, the chamfered portion b is horizontal and the edge e of the rearwardly sloping portion a is spaced from the surface to enable the paint to flow freely. In a modification, Fig. 18, a reservoir 178 screwed upon the end of a handle 170 is connected by an axial bore 173, transverse bore 176, and a longitudinal bore 175 to a nozzle 182 which is reduced at its upper end and pivotally mounted in a slot 171 at the lower end of the handle, a locking-nut being provided on the end of the screw-pivot 187 to hold the nozzle in any angular position. A radial passage 197 connects the bore 175 to an annular channel 185 which is connected by a passage 196 to two diverging passages 194, 195, terminating at apertures in an annular face at the bottom of the member 182. Passages 192, 193 also extending inwardly from apertures in the face are connected to a central hollow stem 189 which extends downwardly from the member 182. The feeding-device comprises three gear wheels 203- 205, Fig. 22, located within overlapping apertures in a stationary flat plate 199 which is disposed between the bottom of the member 182 and a conical sleeve 210 held in position by a flanged collar 213 screwed upon the member 182. The central gear wheel 204 has a sleeve 209 extending downwardly through the sleeve 210 to receive a flanged guide roller 216 which is retained thereon by a friction grip, and a conical tip is fitted on the end of the stem 189. The tool is held so that paint from the reservoir can flow down to the passages 194, 195, whereupon the straight edge or guide, rotation being thus trans. mitted to the central gear wheel which drives the others so that the paint is fed from the passages 194, 195 to the passages 192, 193 and out through the stem 189. The handle is provided with a lateral aperture 174, normally closed by a screw-plug 181, to enable the reservoir to be attached therein under certain conditions of working. In another modification, Fig. 26, the rotation of the guide roller 247 drives a piston plunger 236 in a chamber 221 which receives paint from an adjacent chamber 220 and reservoir handle 223, the paint being expelled through a nozzle 234 at the end of the chamber 221. The roller 247 is mounted on an arm 242 pivoted in a boss 222 on the chamber 221, and the roller spindle 246 carries a worm (not shown) engaging a pinion at one end of a shaft supported by members on the arm 242, a spiral gear at the other end of the shaft serving to drive a shaft 239 carrying a pinion 240 which engages rack teeth 237 on the plunger 236. A clutch is provided to disengage the driving-shaft from the shaft 239. To operate the tool the clutch is first disengaged and the plunger 236 pulled out by hand, whereupon paint is drawn through an inlet valve into the chamber 221. The clutch is then put in and the roller 247 moved over the work, the driving gear causing the plunger to move inwardly. Fresh paint is drawn into the chamber 221 by again disconnecting the clutch and pulling back the plunger. In another form wherein the feeding means comprises two intermeshing gear wheels the paint is fed through a conical plug on which the paint container is mounted in order that it may be swung round and the outlet nozzle is provided with a forward extension or shoe in order that it may ride over small depressions or obstructions.
