PROVISIONAL SPECIFICATION.
Improvements in Machinery for Pleating and Rendering Permanent
Upright or Accordion Pleating or Kilting.
I HOWARD TROTMAN of 228 Euston Road Middlesex Manufacturer do hereby
declare the nature of this invention to be as follows:-
Improvements in the Accordion Pleating Machine.
1st. In the blades.
:-
2nd. In the chamber into which the pleating is pressed & heated.
3rd. In the chamber or frame in which the pleating is cooled and set.
A fuller description of which is as follows.
Instead. of the ordinary flat blades as hitherto used in the Accordion Pleating
Machine I use a blade thick at the back tapering to a blunt edge or blades so
arranged in a slanting direction that the edge only impinges on the material while
the opposite blade is being withdrawn thus avoiding the material being drawn out
with the blade preparitory to its taking another fold.
I line the heated chambers throughout with a thin sheet of brass or other metal
into which the pleating is pressed which prevents the generated steam escaping and
the pleating being scorched or burnt thus avoiding the necessity of damping the
materials or useing damping chambers.
I attach the heated chamber to the cooling chamber in such a manner as to conduct
a small amount of heat downwards thus obviating the generated steam emerging from
a hot chamber condensing on the sides of the cooling chamber and damping the
pleating.

COMPLETE SPECIFICATION.
Improvements in Machinery for Pleating and Rendering Permanent
Upright or Accordion Pleating or Kilting.
HOWARD TROTMAN of 228 Euston Road Middlesex, 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 :-
Improvements in the Accordion Pleating Machine. 1st. Instead of the ordinary
flat blades as hitherto used in the Accordion Pleating Machine, I use blades thick at
the back tapering to blunt edges or blades so arranged in a slanting direction that the
edge only impinges on the material while the opposite blade is being withdrawn (as
shewn in drawing No. 1) thus avoiding the material, being drawn out with the blade
preparatory to its taking another fold.
2nd. I line the heated chambers throughout with a thin sheet of brass or other
metal into which chamber the pleating is pressed thus preventing the generating steam
escaping thus avoiding the necessity of wetting the materials or using damping
chambers.
3rd. I attach the heated chamber to the cooling chamber by bringing them in contact
as shewn in drawing No. 2. so as to conduct a small amount of heat downwards thus
obviating the generating steam emerging from the hot chamber condensing on the sides
of the cooling chamber and damping the pleating.

page_text: B material being pleated, C upper part of chamber into which material is pleated,
D gas barrell with jets, E cooling chamber, F connection of heated to cooling
chamber, G lining of heated chamber.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I clain is-
1st. The arrangement of blades as before described so that only the edge of blade
impinges on the material while the opposite blade is being withdrawn.
2nd. The pleating of material directly into a heated chamber so constructed as to
retain most of the steam generated.
3rd. And the warming of the frame of the cooling chamber.
