to -painting instruments striping instruments.

An object of the invention is to provide an instrument for striping a perimeter.

Another object of the an instrument for apply width throughout its length a work piece and in unit the edge.

Another object of the an instrument adaptable work piece adjacent its invention is to provide a stripe of uniform djacent the edge of 1 spaced relation to invention is to provide for applying a stripe of paint of uniform thickness and width throughout its length adjacent the edge of a work piece.

A further object of the inv ntion is to provide a striping instrument having a guide roller arranged for coaction with piece, and a feeding for delivering paint the perimeter of awork means operated by the roller to the work piece in spaced relation to its perimeter and in proportion to the rate of movement of the instrument.

A further object of the invention is to provide a striping instrument having a container adaptable for the reception of a liquid paint, a positive feeding means connected with the container and an operating means for ranged to operate the feeding the feeding meansiafmeans to apply paint to a work piece n a stripe uniform y Spaced with respect to the perim A still further object of the invention'is for painting stripes of uni;

vide an instrument form width and thicknes to the perimeter of a being of such structure eter or the work piece.

s and in spaced relation work piece, the instrument that the paint will be applied at a rate proportionate to the rate of movement of the instrument.

Other objects of the invention will appear from the following description taken in connection with the accompanying drawing, which forms a part of this specification, and

in which:

Fig. 1 is a side elevation of an instrument illustrating the position thereof when applying a stripe to the edge of a louver;

Fig. 2 is a front elevation;

Fig. 3 is a top plan vi removed; and

ew with the cover plate Fig. 4 is an enlarged top plan view partly broken away and partly in section.

Referring to the drawi ng for more specific de tails of the invention, represents a body portion comprising a rectangular block having a transverse bore 11 in which is threaded a plug 12. The plug has an axial bore 13 in which is positioned a sleeve 14 provided with a flange 15 and a reduced end porti on 16 on which is positioned a coil spring 1'? intermediate the flange 15 and the end of the plug 12. The sleeve 14 is axially bored as indicated at 18 and threaded in the sleeve is a container 19 having a cap 20 provided with the conventional vent 21. The spring 0 bears against the inner end of the plug 12 and exerts pressure against the flange 15 in an axial direction so that the tapered portion 9 of the sleeve is held in sealed relation against the edge of the plug forming the outer end of the bore 18. This spring pressure is such as to permit manual rotation of the sleeve and thus the container carried thereby can be rotated.

Suitably secured on the body portion 10 is a plate 22 having positioned therein a pump mechanism 23, the intake 2% of which is connected by a passage 25 to the bore 11, which communicates with the container 19, and the outlet 26 of the pump mechanism is connected by passages 27 and 28 to a recess 29 in which is fitted an arm 30 axially bored as indicated at 31 to communicate with the passage 28. Positioned in the free end of the arm 3011s a nozzle 32, the passage in which communicates "with'the passage 31 in the arm 30. The nozzle isinaiplane substantially parallel to one side of the body portion. Positioned on the plate 22 over the pump mechanism is a'cover plate 33 and the

plates

22 and 33 are suitably secured to the body as'by screws.

The pump operating means comprises a shaft 3e" suitably connected to one of'the'operating 3 elements of the pump and positioned on the shatt 341s a roller 35 adapted to function as a guide and an operating means for the instrument. As shown, the shaft 34 extends from the bottom of the instrumentwith its axis in a plane substantially parallel to the nozzle 32 and the operating roller on the shaft is positioned for rotation substantially at right angles to the nozzle and adjacent to the discharge end thereof, so that upon engaging the perimeter of a work piece with the roller, the nozzle is positioned for applying a stripe in spaced relation to the perimeter of the work piece to be operated upon.

The body of the instrument is provided with depending lugs 36 arranged in oppositely disposed relation. Each of these lugs supports a plate 37, the upper end of which is curved outwardly as indicated at 38 to provide a suitable finger grip, As shown, the plates 37 are secured to the lugs 36 by screws 39, and an auxiliary finger grip 40 is provided on one end of the instrument, arranged in spaced relation with respect to one of the finger grips.

It will be observed that the relation of the operating means, the roller 35, with respect to the nozzle 32 is such that upon engaging the roller 35 with the edge or perimeter of a work piece, the nozzle will be maintained in the same spaced relation to the perimeter whether the instrument moves in a straight or curved path, and that the feeding means which is operated at a rate proportionate to the rate of movement of the instrument, will deliver paint or lacquer from the container to the nozzle for application on the work piece adjacent the perimeter thereof and and having a tapered portion adapted to frictionally engage in sealing relation with the plug, spring means in the body cooperating with the plug and sleeve to normally maintain frictional engagement therebetween, a fluid container fixed to and communicating with the sleeve, and a nozzle carried by the body, and communicating with the sleeve.

2. In a striping instrument, a body having a fluid dispensing nozzle extending therefrom, plates secured to two opposite sides of the body, said plates terminating in outwardly curved grips extending above the top of the body, and an angular finger grip associated with one side of the body and having a portion in parallel relation with one of the plates.

3. In a striping instrument, a body having a nozzle extending therefrom, a sleeve carrying a fluid container rotatably mounted in the body, said container communicating with the nozzle, and means including a spring normally holding the sleeve in sealed relation with the body and in any position of rotation.
