A TTORNE Y Patented Nov. 13, 1934 UNITED STATES PAINT STRIPING NOZZLE Frank P.` Ryan, Detroit, Mich., assignor to Chrysler Corporation, Detroit, Mich., a corporation of Delaware Application November 13, 1930, Serial No. 425,435

2 Claims.

The main objects of the invention are to provide an improved nozzle for a paint striping device; to provide a nozzle of this kind which cooperates with the work upon which paint is being applied to guide the movement of the striping device; and to provide a paint striping nozzle having a restricted paint outlet which is held in a predetermined spaced relation to the work by a pair of nibs so as to apply stripes of 1 uniform appearance on the work.

Further objects of the invention are to provide a paint striping nozzle which is adapted to simultaneously stripe the edge and adjacent side portions of an article; to provide a nib on a vl nozzle of this type which has a well for receiving some of the paint from the outlet and which is adapted to hold paint in engagement with the edge portions of the article so as to allow the paint to creep up the outer side of the work; to

4`.provide a nozzle of this kind which forms an integral bead-like lm of paint around the edges of a sheet-like piece of work; and to provide a paint striping instrument which is particularly adapted for ornamenting the edge portions of f the louvers of a vehicle hood.

An illustrative embodiment of my invention is shown in the accompanying drawing, in which:

Fig. 1 is a side elevation of a paint striping device embodying my improved nozzle and diagrammatically illustrating the manner in which it is used on vehicle hood louvers.

Fig. 2 is a central section of the nozzle.

Fig. 3 is a fragmentary transverse section of the edge portions of a louver which have been striped by a device having my improved nozzle.

In the form shown, my improved. nozzle 1 is illustrated in connection with a paint striping device which includes a body portion 2 having a rotatably supported handle 3 which is provided with adjustable guiding mechanism 4. The guiding mechanism includes an extensible rest 5 which may be adjustably positioned so as to engage a surface of the work or article being striped for holding the outer extremity of the nozzle 1 in a predetermined relation to the article.

The striping device has a paint reservoir 6 which communicates with the body portion 2 and with a passage 7 formed in a tubular boss 8 which is provided on the extreme left end of the body portion, as shown in Fig. 2.

The nozzle 1 has a body portion 9 in the right end of which, as viewed in Fig. 2, is formed a passage or recess 10 for receiving the tubular boss 8. Extending centrally of the body portion 9 of the nozzle 1 is a passage 11 in which a paint discharge duct 12 is mounted. The duct 12 extends outwardly frorn the body portion 9 of the nozzle and has an outlet 13 at its outer extremity.

Formed on the body portion 9 of the nozzle 1 is a curved nib 14 which protrudes beyond the outlet 13 of the duct 12 and extends slightly into the path of the paint which is discharged therethrough. This nib is adapted to engage one side` surface oi an article so as to hold the outlet 13 of the duct in a predetermined spaced relation from the surface of the articleupon which paint is directly sprayed. The nozzle l has a concave nib l5 which extends beyond the extremity of the nib 14 and forms a seat for receiving an edge portion of the article or work. This nib has a well 16 which accumulates some of the paint that is discharged from the outlet 13 and holds it in engagement with the edge portions of the work.

When the nozzle is used in striping the lower edge portions of sheet metal article such as the vehicle hood louvers 17 shown in Fig. 1, it is preferable to have the nib 15 extend beyond the side surface 18 which is opposite from the side surface against which the nib 14 engages, so as to allow the paint in the well 16 to flow upwardly by capillary attraction onto a limited portion/of the inner side surface 18 of the lo-uver.

In operation, the striping device is moved lengthwise of the edge portions of the article upon which a stripe is being formed. During this movement, the duct 12 sprays paint directly upon one side surface of the article while the other side surface and edge portions of the article receive paint from the well 16 of the nib 15. The paint forms a continuous bead-like trim having a cross section similar to that shown in Fig. 3. Enamels, paints, varnish, gild or similar liquid ornamenting substances may be striped on the edge portions of articles in the above manner and regardless of the nature of the substance used, the forward end or nose of the nib 14 shields those portions of the work which it is not desired to stripe, thus forming a well defined and straight edged stripe. If desired, the nib 1 may be inverted with respect to its position shown in Fig. 1 so as to form a stripe on the upper edge portions of an article.

Although but one specific embodiment of this v invention has herein been shown and described, it will be understood that various changes in the size, shape and arrangement of parts may be made without departing from the spirit of my invention and it is not my intention to limit its scope other than by the terms claims.

What I claim is:

1. In a striping device including a body portion having a striping material discharge passage, a striping pen mounted on said body portion adapted to simultaneously apply striping material on adjacent angularly disposed side and edge surfaces of an article, said pen comprising a longitudinally extending discharge tube communicating with said passage and having an outlet, a concave pen nib having a cavitytherein and extending in advance of the outlet of said tube and having spaced edge portions disposed in a common plane located at the lower extremity of said outlet and substantially parallel to said tube for receiving the edge portions of said article and positioning the outlet of said'tube to discharge striping material directly upon the side surface of saidarticle adjacent said edge thereof, the cavity of said pen nib extending substantially to the forward extremity thereof forcollecting striping material and applying the latter to the edge portions of said article, and a second pen nib extending over said. tube and of the appended terminating at a location between the forward extremity of said rst pen nib and the outlet of said tube for abutting said side surface of said article and predetermining the distance from the latter to said outlet.

2. In a striping device including a body portion having a striping material discharge passage, astriping pen mounted on said body portion adapted to simultaneously apply striping material on adjacent angularly disposed side and edge surfaces of an article, said vpen comprising a longitudinally extending discharge tube communicating with said passage and having -an outlet, a concave pen nib having a cavity therein and extending in advance of the outlet of said tube and having spaced edge portions disposed in a common plane located at the lower extremity of said outlet and substantially parallel to said tube for receiving the edge portions of said article and positioning the outlet of said tube to discharge striping material directly upon the side surface of said article adjacent said edge thereof, and a second pen nib vextending over said tube and terminating at a location between the for,- ward extremity of said first mentioned pen nib and the outlet of said tube for abutting said side surface of said article and predetermining the distance from the latter to said outlety the cavity of said iirst mentioned pen nib extending beyond the forward extremity of said second pen nib further than the thickness of said article for collecting striping material and applying the same to the edge portions of said article and t0 the opposite side surface thereof and all portions of said second pen nib being disposed above said plane of the edge portions of the rst mentioned pen nib. t
