IMPROVEMENTS IN PAPER SATINING MACHINES
Year: 1868

page_text: LETTERS PATENT to Thomas Christy, of the City and County of New
York, & State of New York, in the United States of America, for
the Invention of "IMPROVEMENTS IN PAPER SATINING MACHINES."
COMPLETE SPECIFICATION filed by the said Thomas Christy at the
Office of the Commissioners of Patents, with his Petition and
Declaration, on the 2nd June 1868, pursuant to the 9th Section
of the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
CHRISTY, of the City and County of New York, & State of New York, in
the United States of America, send greeting.
WHEREAS I am in possession of an Invention for "IMPROVEMENTS
IN PAPER SATINING MACHINES," and have petitioned Her Majesty to grant
unto me, my executors, administrators, and assigns, Her Royal Letters
Patent for the same, and have made solemn declaration that I am the
true and original Inventor thereof.

page_text: NOW KNOW YE, that 1, the said Thomas Christy, do hereby declare
that the following Complete Specification, under my hand and seal,
fully describes and ascertains the nature of the said Invention, and
in what manner the same is to be performed, in and by the following
statement:-
The accompanying Drawings form a part of this Specification, in which
Figure 1 represents a side elevation of this Invention; Figure 2 is a
transverse vertical section of the same; Figure 3 is a plan or top view
of the same. Similar letters of reference indicate like parts.
These improvements relate to a class of machines used for imparting
a polish or finish to paper by means of rotary brushes, and commonly
known "as paper satining" machines. The machine in common use for
the purpose consists of a large central rotating drum of wood or metal,
around which the paper passes. Supported in bearings at intervals
around its upper circumference are placed several rapidly revolving
brushes of small diameter, which being brought to bear upon the paper
passing over the central roller smooth and finish the surface of the same.
My machine effects the operation with greater perfection, and with the
expenditure of less power. I employ but one brush of large diameter.
F and G represent the framing of my machine which supports the
various working parts thereof. The paper wound upon roller D is passed
alternately under and over the rollers B and C, after which it is wound
up upon the roller D'. The rollers B are of polished metal, and serve to
press the paper in its onward movement through the machine against
the rotary brush A, which is put into rapid motion by means of a belt on
pulley E, or in any way most convenient. The rollers Bare driven by
gearing a, which are actuated by a small gear on the shaft of the brush A.
They move in the same direction as the brush A, but at a less speed,
thereby retarding the passage of the paper, retaining it longer in contact
with the brush A. The rollers C are loose in their bearings, and are for
the purpose of raising the paper from the brush A after passing under
the rollers B. The roller D¹ upon which the paper is wound after
passing through the machine may be revolved by hand or by means of
pulleys, and a belt from the shaft of brush A, in which latter case the
tension of the paper may be regulated as desired by means of a friction
clutch. The set screws fare for the purpose of adjusting the position of
rollers B, thus compensating for the wearing down of the brush A con-

page_text: sequent upon use. The intermediate gears between the rollers B are
also adjusted by means of the arms b, upon which they are carried.
What I claim as my Invention, and desire to secure by Letters Patent
is, the single central revolving brush A and the pressure rollers B, which
may be either loose or driven by gearing or belting from the central
shaft, together with the rollers C, arranged and operating substantially
as and for the purposes described.
In witness whereof, I, the said Thomas Christy, have hereunto
set my hand and scal, this Twelfth day of May, in the year of
our Lord One thousand eight hundred and sixty-eight.
THOMAS CHRISTY. (L.S.)

HENRY W. BULKLEY.
