An Improved Method of and Apparatus for Applying Paint, Lacquer,
and other Coatings.
We, JOHN H. DAVIS, of 523, Austin Avenue, Electrician, LORENZO L. MERRIMAN,
of 1723, Roscoe Street, Merchant, ALBERT E. JESSURUN, of Granada Hotel,
Merchant, and WILLIAM R. 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:
Our invention relates to the art of applying paint, lacquer, glazing, varnish
and other similar coatings
The main object of our invention is to provide for feeding the coating material
in a continuous layer, so as to replace the part taken up by the article that is being
coated. Another object is to provide for suitably supporting such article during
the operation of coating same.
We accomplish these objects by the method and apparatus hereinafter described
with reference to the accompanying drawing, in which
Figure is a perspective view of the apparatus with which we put our invention
into practice.
Figure 2 is a vertical section of same on a plane just behind the forward wall
and legs of the tank
The apparatus shown in the drawing consists of a tank 1 supported by legs 13;
a pipe 2 which serves as an outlet for the tank at 14 and connects with a coil 3,
which communicates with the tank at 15 a burner 4, for heating the coil: a
platform 6 for supporting the article to be coated, and a tank 9 for containing the
pigment or coating material
The line 11 represents the water line, or the upper surface of a supporting
liquid upon which a layer of coating material may be floated. The line 12 repie-
sents the upper surface of the coating material.
The supporting liquid may be of various kinds It should be of a greater specific
gravity than the coating material, and should be substantially non-adhesive to the
coating material when the latter is removed by the article being coated
We have used as such supporting liquid either mercury, or water charged with
various salts, such as common salt, sugar, sulphide of zinc, sulphate of copper,
and silicate of sodium.
The platform 6 is preferably adjustable in height
:
This adjustment in the form
shown, is accomplished by the binding screws 8. extending through slots in the
members 16 and 7. The members 16 are rigidly attached to the platform 6, and
the members 7 are rigidly attached to the bottom of the tank. This platform
should advisably be adjusted to a plane slightly below the upper surface of the
supporting fluid.
The outlet 14 is preferably lower than the inlet 15 The latter is nearer the
tank 9 and the former at the opposite end of the tank 1, so that a flow of the

page_text: supporting liquid may be obtained from the end of the tank where the coating
material is fed, toward the opposite end.
The supporting liquid fills the pipe 2 and coil 3. The coil is heated by the
burner 4 which is fed by the gas pipe 5.
A
It will be understood that when the liquid in the coil is heated, same will
rise and pass into the tank at 15 The inlet 15 is preferably slightly below the
upper surface of the supporting liquid. The rising of the heated liquid in the
coil, causes a flow of the cooler liquid into the pipe 2, through the outlet 14
constant current of the supporting liquid is thus obtained towards the end of the
tank at 14. The strength of the current will be regulated by the degree of heat
applied to the coil This is regulated by the burner
It will be understood that when the coating material is fed to the tank 1,
through the cocks 10, the same will be carried by the current towards the opposite
end of the tank.
The operator will preferably stand at the end of the tank towards the outlet 14
When the layer of coating material reaches that end, the article to be coated is
laid over or rolled upon the platform 6 with the layer of coating material interven-
ing. This adheres to the surface of the article, and when the article is removed,
breaks away from the remainder of the coating material in the tank. The current
carnes such remainder forward, renewing the part removed
Coating materials of different colors may be fed at the same time, from separate
compartments which may be formed in the tank 9 The current will carry these
colors together so as to form various designs. The surface may be agitated or
stirred so as to form marbled, streaked or other mottled designs.
In specifying means for inducing a current, we do not include such as a tool in
the hands of an operator, whereby the surface of the liquid could be paddled
forward by dipping the tool through the layer of coating material, but confine
ourselves to means which may be operated without puncturing or breaking the
laver.

The office of the parts described will be understood from the foregoing explana-
tion, and it is plain that the parts may be considerably varied without departing.
from the spirit of our invention. We do not therefore confine ourselves to. the
details of construction.
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. The herein described method of applying paint and similar coatings, which
consists in first forming a layer of the coating material upon a supporting liquid
of greater specific gravity by feeding the same upon the sei face of the supporting
liquid, and at the same time inducing a current of the supporting liquid in a
direction away from the place of the said feeding without puncturing the said
layer, whereby the said layer is continually renewed in the direction of the said
feeding, and then bringing the surface to be coated in contact with the said layer
2. A device for applying paint and similar coatings, comprising a tank for
containing the supporting liquid, means at one end of the tank for feeding a layer
of coating material upon such liquid, and means adapted to induce a current in the
said liquid towards the other end of the tank without puncturing the said layer,
substantially as described.
3. A device for applying paint and similar coatings, comprising a tank for con-
taining the supporting liquid, means for feeding the coating material upon such
liquid, at one end of the tank, means for inducing a current in the said liquid
towards the other end of the tank; and a vertically adjustable platform in the said
tank adapted to be adjusted below and substantially parallel with the upper surface
of the supporting liquid, substantially as described.
4 A device for applying paint and similar coatings, comprising a tank for
containing the supporting liquid, means for feeding the coating material upon

page_text: such liquid at one end of the tank, an inlet at the said end of the tank, an outlet
at the opposite end thereof, a pipe or other fluid-tight compartment connecting the
said inlet and outlet independent of the main compartment of the tank, and means
for heating such pipe or other compartment toward the inlet end, substantially
as described.
5. A device for applying paint and similar coatings, comprising a tank for
containing the supporting liquid, means for feeding the coating material upon such
liquid, at one end of the tank, an inlet at the said end of the tank, an outlet at the
opposite end thereof, a pipe or other fluid-tight compartment connecting the said
inlet and outlet independent of the main compartment of the tank, the said pipe
or other compartment extending through a plane below the said outlet and inlet,
and means for heating such pipe or other compartment toward the inlet end,
substantially as described
6 A device for applying paint and similar coatings, comprising a tank for
containing the supporting liquid, means for feeding the coating material upon
such liquid, at one end of the tank, an inlet at the said end of the tank, an outlet
at the opposite end thereof, the said outlet being in a lower plane than the said
inlet, a pipe or other fluid-tight compartment connecting the said inlet and outlet
independently of the main compartment of the tank, and means for heating such
pipe or other compartment toward the inlet end, substantially as described.
7. A device for applying paint and similar coatings, comprising a tank for
containing the supporting liquid, means for feeding the coating material upon such
liquid, at one end of the tank an inlet at the said end of the tank, an outlet at the
opposite end thereof, the pipe 2 and coil 3 connecting the said inlet and outlet, and
a heater for the said coil, substantially as described
8. A device for applying paint and similar coatings, comprising a tank for
