PROVISIONAL SPECIFICATION.
Improvements on Machines which are applicable to Tarring Various
Materials and which are of Especial Advantage in Tarring
Fibrous Materials, such as Cotton, Flax, Hemp, Jute, and the
like.
JAMES FARMER ANDERSON, Airlie Works, Dundee, Manufacturer, do hereby
declare the nature of this invention to be as follows:-
-
Improvements on machines which are applicable to tarring various materials and
which are of especial advantage in tarring fibrous material.
This invention relates to the continuous application of the tar, and consists of
an improved arrangement for tarring the material, while passing over an open
conductor.
22
In existing machines for the purpose the material is passed through a cistern or
" or "sticky
other vessel containing the tar and on account of the "clammy
nature of the liquid a considerable difficulty has been experienced in getting con-
tinuous or unbroken delivery.
This arrangement consists in passing the material to be tarred over an open
conductor, and the tar is applied in a continuous stream from above by means of a
pipe or other conductor, superfluous tar being passed through a perforated hollow
in the conductor or squeezed out by being passed through a pair of rollers.
Dated the 24th day of November 1890.

COMPLETE SPECIFICATION.
Improvements on Machines which are applicable to Tarring Various
Materials and which are of Especial Advantage in Tarring
Fibrous Materials, such as Cotton, Flax, Hemp, Jute, and the
like.
JAMES FARMER ANDERSON, Airlie Works, Dundee, Manufacturer, 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:-
This invention relates to the continuous application of the tar, and consists of an
improved arrangement for tarring the material while passing over
conductor.
an open
In existing machines for the purpose, the material is passed through a cistern, or
other vessel containing the tar, and on account of the "clammy" or "sticky" nature
of the liquid, a considerable difficulty has been experienced in getting continuous
or unbroken delivery.
The arrangement consists in passing the material to be tarred over an open
conductor, and the tar is applied in a continuous stream from above by means of a
pipe or other conductor, superfluous tar being passed through a perforated hollow
in the conductor, or squeezed out by being passed through a pair of rollers.
The material is fed on to a conductor at the point marked D in drawings.
A continuous motion being transmitted to the material by means of the two rollers
marked E E..
At the point marked A. the conductor is hollowed and perforated.
Immediately above at C the tar is fed from a curved pipe, by means of a steam jet
or raiser shewn at B, (which also heats the tar so as to attain its proper consistency).

page_text: This is enclosed in a cistern containing the tar, which is kept at a level indicated
by the dotted line F.
Superfluous tar falls through the perforations in the conductor shewn in the plan
at C or is squeezed out between the rollers E E and flows back into the cistern.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1st. The method of raising and heating tar by means of a steam jet inserted
into a pipe.
2nd. The method of applying the tar in its heated state, by discharging from said
pipe over the material.
3rd. The open perforated conductor as used for the purposes herein described.
Dated this 15th day of January 1891.
