Patented July 2, 1940 LIQUID SPRAYING APPARATUS Charles Radtke, West New York, and Henry Bellman, Wood-Ridge, N. .L, assignors to Lorr Laboratories, Paterson, .L, a corporation of New Jersey Application October 17 1938, Serial No. 235,438

zoiaims. 01. 101-414) This invention relates to improvements in spraying apparatus more especially employed to apply a .coloring substance to a portion of the surfaceof an article such as a container or its closure. l v More specifically, the apparatus is adapted for the applicationof vari-colored liquid finger-nail polishes or lacquers to parts of bottle stoppers each shaped to simulate a finger-nail, said part on each stopper to be sprayed with a liquid colored the same as that to be enclosed in the container so that prospective purchasers may determine the color or tint of the contents of said container by observance of the nail simulation on the stopper thereof.

An object of the invention is to provide an improved apparatus of simple and practical construction by means of which a liquid polish or lacquer may be rapidly applied to only a certain defined area of an article such as a container or its closure. v

The above and other objects will appear more clearly from the following detailed description when taken in connection with the acompanying drawings which illustrate a preferred embodiment of the inventive idea. In the drawings:

Figure 1 is a fragmentary top plan view of an apparatus constructed in accordance with the invention.

Figure 2 is a fragmentary side elevation thereof, partly in section.

Figure 3 is an enlarged fragmentary elevation showing a container and its closure or stopper in the position on the turntable of the apparatus in which liquid is to be sprayed onto a D01?- tion of said closure. t

Figure 4 is an enlarged sectional view taken at right angles to Figure 3.

Figure 5 is atop plan view of a portion of the turntable showing. a mask in position thereon and ready to receive the closure of a container. Figure 6 is a perspective view of the mask employed, and, l

Figure 7 is an elevation of the container and its closure in an upright position after application of a liquid to a portion of i said closure.

One of the specific applications of the invention and that which is shown in the accompanying drawings pertains to the spraying of a finger-nail polish or lacquer onto a defined area of the closure 8 of a bottle ii, both of which may be of any design. Preferably, the closure 8 is provided with an offset or raised portion [0 of a shape simulating that of a fingei nail and it is the purpose of the present invention to apply to the surface of said portion in a polish the color of which is identical with that to be poured in the container 9.

The apparatus for accomplishing this purpose preferably comprises a turntable in the form of a disc ll mounted for rotation above a support-f ing frame I2 and having a bearing upon rollers 93. The turntable H carries a vertically disposed shaft M mounted in bearings within the frame l2 and provided with a large gear 55. Meshing with said gear is a pinion l6 driven from a conventional gear reduction device it to which is connected the prime mover la in the form of an electric motor. Through the gear reduction l1, the shaft l4 and turntable ii are rotated at the desired speed. Provision is made for supporting a plurality of the containers ii in an inverted position upon the turntable it during the spraying operation. For this purpose there is provided a supporting ring consisting of a plurality of sections l9 each of which is individually attached to the upper surface of the turntable l l by means of wing nuts 28 extending through the latter and the extensions 2! formed at the extremities of the inner edges of said section. This construction enables the various sections 19 to be detached from the turntable II whenever it is desired to remove said sections for the purpose of cleansing the same of any accumulation of liquid which may adhere thereto during a spraying operation. Each of the sections [9 is provided with a series of openings 22 for receivinga closure 8 and each opening is reduced at its lower end to form a supporting flange 23 the purpose of which will presently appear. I

In order that liquid directed toward the 010- port the mask in its normal inverted position, as

best shown inFigure 4. The mask is provided in the body portion thereof with an opening 26 shaped similarly to the offset portion of the area It so that said portion will be exposed through said opening when the closure 8 is introduced into the mask. Opposed to the opening 26 in the mask there is also provided a slot 27 which ex- PATENT oFFica v a tends through the flange 25 and which is adapted to receive an elongated key 28 projecting from a surface of the closure 8 diametrically opposite the area It. When the key 28 is inserted into the slot 27 the area I0 is registered with the opening 26 in the mask and said key and slot cooperate to prevent any turning movement of the closure 8 relative to the mask which might otherwise expose a portion of the closure 8 not intended to be sprayed with the liquid.

One or more spraying devices may be arranged about the exterior of the turntable H and disposed so as to direct a liquid such as nail polish onto the areas "I of the various closures as they are rotated relative to said device. As shown, two spraying devices 29 of any standard construction are suitably supported in spaced circumferential relation about the turntable and the nozzles are so arranged as to direct the spray of liquid onto the exposed portions it of the closures 8 as the latter are rotated. To prevent excess diffusion of the spray and fumes therefrom, a suction head may be arranged beneath the turntable in opposed relation to each of the sprayers 29 and said heads may be connected to a conduit 3i leading to; an air suction fan (not shown).

What is claimed is: 1. In combination, a turntable, a sectional supporting ring carried bysaid table, with each section of saidrin'g individually to said turntable;

means to mask a portion of each of said articles, means to spray a liquid onto the unmasked portion of each article, and means to rotate said turntable to move said articles relative to said spraying means.

2. In combination, a turntable, a sectional supporting ring carried by said table, with each section of said ring having a series of openings therein for receiving and supporting articles to be sprayed, means to detachahly secure each section of said ring individually to said turntable, means to mask a portion of each of said articles, means to spray a liquid onto the unmasked portion of each article, means to rotate said turntable to move said articles relative to said spraying means, and a suction device opposed to said spraying means.
