COMPLETE SPECIFICATION.
Improvements in Apparatus for the Application of Paint, Lacquer
and other Coatings.
We, JoHN HENRY DAVIS, of 523, Austin Avenue, Electrician, LORENZO L.
MERRIMAN, of 1723, Roscoe Street, Merchant, ALBERT EDWARD JESSURUN, of
Granada Hotel, Merchant, and WILLIAM RICHARD RUMMLER, of 84, Madison Street,
Attorney at Law, all of the City of Chicago, County of Cook and State of Illinois,
one of the United States of America, do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:
1
Our invention relates to the method and apparatus for painting, described in
the Specification accompanying our Application for Letters Patent filed
February 7th, 1899, No. 2719, and has particular reference to the means for
feeding the paint upon the supporting liquid.
The main objects of our present invention are to provide for making the films
or coatings, which are formed upon the supporting liquid, of different variegated
and mottled designs, and to provide for controlling the general character of the
design on each film.
We accomplish these objects by the apparatus illustrated in the accompanying
drawings, in which Fig. 1 is a top plan of a device embodying our invention; and
Fig. 2 is a partly sectional elevation of the same.
The tank 1 for containing the paint supporting liquid is shown mainly broken
away, and the surface of the liquid is indicated by the line a.
The paint pots or receptacles 2, are supported by brackets 3, on the member 4 of
the frame.
any
The member 4 is shown partly broken away. This will be secured in suitable
manner, above the tank containing the supporting liquid.
The pots 2 are essentially the same, but carry feeders of different form.
Each pot has a plunger-head 5 therein supported by an arm 6 carrying a weight 7
and fastened by a pin 8 to the lever 9 which is fulcrumed at 10 on an arm 11
secured to the upper part of the pot.
The cams 12 are rigid on the shafts 13 which are journalled in arms 14 on the
member 4 of the frame.
Each shaft 13 is connected with suitable driving power for revolving same, not
shown in the drawings.
It will be seen that the revolution of the shafts 13, through the cams 12 acting
under the free ends of the levers 9, intermittently raises the plunger-heads 5; the
weights 7 urging same normally downwardly.
The office of the plunger-heads is to keep the paint agitated and in free flowing
condition.
The parts below the cocks 15, control the variety of the designs in which the
paint forms upon the supporting liquid.
In the form shown at the right of Fig. 2, a tube 16 is threaded to the cock 15.
The tube carries a wick 17 made of coarsely woven wool, spun yarn, or other

page_text: similar material. The wick reaches just into the surface a of the supporting liquid,
and furnishes a steady unbroken flow of paint, which, through the current of the
supporting liquid forms a streaky coating upon same.
This coating is carried by the current, in the direction of the arrow.
The next feeder has a grooved needle 18 fastened to the lever 19 which is
fulcrumed at 20 on the arm 21 of the frame.
The needle 18 is flared at the upper end in funnel shape so as to catch the paint
dropping from the cock 15 above same.
The free arm of the lever 19 is urged normally downward by the spring 22,
secured to same and to the arm 21.
The cam 23 is rigidly mounted on the shaft 24, journalled in the arm 21.
The shaft 24 is connected with suitable driving power for revolving same, not
shown in the drawings.
The shafts 13 and 24 may all be connected by pulleys, so as to be driven
simultaneously.
The cam 23 intermittently raises the free end of the lever 19 against the action
of the spring 22 so as to give the needle 18 a vibratory motion, as indicated by
the dotted lines. This scatters the paint in drops from the end of the needle, the
same running down the groove in the side of the needle.
The drops from the needle spread out in different shapes, sinking into the film
already formed, and some running together so as to form a marbled surface in
connection with the ground color furnished by the feeder to the right, before
described.
The feeder at the left of Fig. 2 is in the form of an atomizer. This consists
of a funnel 25 secured to the pipe 26 below the cock 15. The pipe 26 communicates
with the air-chamber 27 which is supported on the member 28 of the frame. The
cover of the air-chamber is a flexible diaphragm 29 which is held normally upward
by the spring 30 in the position indicated by the dotted line, b.
A weight or plunger 31 is suspended above the diaphragm by the arm 32
which is slidingly supported in the bearing-sleeve 33 in the member 4 of the
frame.
The upper end of the arm 32 is curved so as to permit the free rotation of the
cam 12 and project over same and under the free end of the lever 9 at 34.
The pipe 26 has an extension 35 curved slightly upward and forming a drip-pan
under the funnel 25.
It will be seen that when the plunger 31 is raised by the action of the cam 12,
the chamber 27 fills with air, and when the plunger drops upon the diaphragm, the
air is suddenly expelled through the pipe 26 so as to scatter the paint dropping
from the funnel, in fine spray which settles into the coating already formed by the
other feeders.
This being of a different color. gives same the appearance of a fine cross-
grain.
The film is so thin that when pigments of about the same specific gravity are
used, its appearance will be the same on both sides, so that an article treated by
bringing same in contact with the upper surface of the film will show, in reverse,
the same design as that presented toward the article.
It will be seen that the different forms of feeders may be used singly or in
combination, and that the extent of flow from each may be regulated by the cocks,
so that an innumerable variety of films may be formed.
The speed and direction of the current will also influence the character of the
design.
When a certain current is used, and the feeders have a certain adjustment,.
the film formed thereby will have the same general character throughout, though
varving in the specific designs displayed in different parts.
By the use of the first two feeders described, an imitation marble finish may be
applied, with or without the feeder last described.

page_text: By the use of the first and last feeders, omitting the second, an imitation wood
finish may be applied.
It will be understood that the feeders may be used in series and may be arranged
in any desired order for producing designs of different general character.
In general my device embodies feeders for producing three distinct classes of
finish. The first, a streaky finish; the second, a variegated finish formed of
drops running together in different forms; and the third, a finely spotted or
veiled finish.
It is plain that the details of construction of my device may be altered in
numerous ways without departing from the spirit of our invention. We therefore
do not confine ourselves to such details.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:
1. In an apparatus of the class described, the combination of a tank containing
a flowing supporting liquid; a paint feeder having its feeding end in contact
with the surface of said Huid, and adapted to feed the paint upon said surface in
the form of a streaked film; a second feeder having a vibratory motion adapted to
throw the paint in scattered drops upon said surface, and a third feeder adapted
to throw a fine spray of paint upon said surface, substantially as and for the
purposes specified.
2. In an apparatus of the class described, the combination of a tank containing
a towing supporting liquid, a paint feeder having its feeding end in contact
