PROVISIONAL SPECIFICATION left by the said Ferdinand Rath at the:
Office of the Commissioners of Patents, with his Petition, on the:
23rd January 1874.
I, FERDINAND RATE, of Goldsmith Street, in the City of London, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
ROLLERS OR APPARATUS FOR MAKING PLAITED, CREASED, OR FOLDED FABRICS," to.
be as follows:-
This Invention has for its object improvements in rollers or apparatus >
for making plaited, creased, or folded fabrics for collars, trimmings, shirt,
fronts, and other purposes, whereby the plaits or folds in place of folding,
over in one direction successively are folded in opposite directions to
form what is known as the box plait or double box plait heretofore made i
:

page_text: by hand. For this purpose the rollers employed in accordance with my
improvements for creasing the fabrics are formed with ribs and grooves,
which gear together in like manner to cog wheels, the ribs and grooves
being formed with steps or sets off in them corresponding with the
number and width of the creases required for producing (by subsequent
folding) box or double box plaits.
The rollers are supported in bearings in a frame, as is well understood,
but according to my improvements the lower roller is supported and
borne up against the upper roller by a spring or springs (or otherwise),
the pressure of which can be adjusted.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Ferdinand Rath in the Great Seal Patent Office
on the 23rd July 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FERDINAND
RATH, of Goldsmith Street, in the City of London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-third day of January, in the year of our.
Lord One thousand eight hundred and seventy-four, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Ferdinand Rath, Her special licenso
that I, the said Ferdinand Rath, my executors, administrators, and
assigns, or such others as I, the said Ferdinand Rath, my executors,
administrators, or assigns, should at any time agree with, and no others,
from time to time and at all times thereafter during the term therein
expressed, should and lawfully might make, use, exercise, and vend,.
within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN ROLLERS OR
APPARATUS FOR MAKING PLAITED, CREASED, OR FOLDED FABRICS," upon the
condition (amongst others) that I, the said Ferdinand Rath, my executors
or administrators, by an instrument in writing, under my, or their, or
one of their hands and seals, should particularly describe and ascertain
the nature of the said Invention, and in what manner the same was to
be performed, and cause the same to be filed in the Great Seal Patent

page_text: BIA Calculatory arter
of the said Letters Patent.
NOW KNOW YE, that I, the said Ferdinand Rath, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say :-
This Invention has for its object improvements in rollers or apparatus
for making plaited, creased, or folded fabrics for collars, trimmings, shirt
fronts, and other purposes, whereby the plaits or folds in place of folding
over in one direction successively are folded in opposite directions to
form what is known as the box plait or double box plait heretofore made
by hand. For this purpose the rollers employed in accordance with my
improvements for creasing the fabrics are formed with ribs and grooves
which gear together in like manner to cog wheels, the ribs and grooves
being formed with steps or sets-off in them corresponding with the.
number and width of the creases required for producing (by subsequent
folding) box or double box plaits.
The rollers are supported in bearings in a frame, as is well under-
stood, but according to my improvements the lower roller is supported
and borne up against the upper roller by a spring or springs (or other-
wise), the pressure of which can be adjusted.
And in order that my Invention may be clearly understood and readily
carried into practice I will proceed to describe the Drawings hereunto
annexed, Figure 1 of which shows an end view of a pair of rollers and
apparatus suitably arranged for making plaited, creased, or folded fabric
in accordance with my improvements. The ribs and grooves formed on
the rollers a, b, Figure 1, are suitable for making what is known as the
single box plait; the ribs and grooves shown at Figure 2 being suitably
formed for making double box plaits in the fabrics passed between them.
c, c, are levers moving on fulcrums at c¹ on the end framings or standards
which support or carry the bearings of the rollers a and b. The necks
of the lower roller 6 enter an opening in each of the levers c, which are
connected by a bar c', to which a link c* is attached connected to a
treadle which can be acted by the foot of the operator when required to
depress the lower roller b, and form an opening between the two rollers
for the introduction or withdrawal of the fabrics to be plaited or creased.
6¹ are springs for pressing up the bearings of the lower roller 6, the

page_text: pressure being adjusted by the set screw 6. d is the driving axis, which
carries the fast and loose driving pulleys and toothed pinion d³,
which takes into and drives a toothed wheel a' fixed on the axis of the
upper roller the ribs of which take into and give motion to the lower
roller b. e, e, are gas pipes for heating the inner surfaces of the rollers a
and b, which are formed with a passage through them. f is a table, over
which the fabric is fed in between the rollers a and b.
a,
Having thus described the nature of my improvements, and the manner
of performing or carrying the same into practice, what I claim is, the
improved arrangement and construction of rollers and apparatus for
making plaited, creased, or folded fabrics, substantially in the manner
herein-before described and represented in Figures 1 and 2 of the.
Drawings hereunto annexed.
I also claim, the improved manufacture of plaited, creased, or folded
fabrics substantially in the manner herein-before described.
In witness whereof, I, the said Ferdinand Rath, have hereunto set.
my hand and seal, this Eighteenth day of July, in the year of
our Lord One thousand eight hundred and seventy-four.
