Sealed the 31st March 1868, and dated the 16th October 1867.
PROVISIONAL SPECIFICATION left by the said Frederick Dunch Frost
at the Office of the Commissioners of Patents, with his Petition, on
the 16th October 1867.
I, FREDERICK DUNCH FROST, of the Firm of Frost Brothers, of London
Street, in the City of London, Rope Manufacturers, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN ROLLERS USED IN FRAMES
FOR DRAWING AND SPINNING OR PREPARING FIBROUS MATERIALS," to be as
follows:-
My Invention consists in forming the front rollers used in frames for drawing
and spinning or preparing fibrous materials with a groove of
shape
in its periphery, and in placing in the bottom of this groove leather or other
suitable yielding material. The ordinary lower roller or boss works in the
groove and draws the fibrous material through.
My Invention further consists in constructing grooves in the peripheries of
the front rollers used in frames for drawing and spinning or preparing fibrous
materials in such manner that leather or other material placed in such grooves
may be securely held therein without any other appliance. For this purpose

page_text: I form at the bottom of the groove at each side and at right angles thereto
another groove to receive the edge of the leather or other material. The
width of the leather is greater than that of the first or outer groove, and it is
partly doubled to allow it to be slipped in. The recess or compound groove
in the periphery of the roller is therefore of this shape or approximately

that I, the said Frederick Dunch Frost, my executors or administrators, by
an instrument in writing under my, or their, or one of their hands and seals,

NOW KNOW YE, that I, the said Frederick Dunch Frost, do hereby
declare the nature of my said Invention, and in what manner the same
is be performed, to be particularly described and ascertained in and by the
following statement thereof, reference being had to the Drawings hereunto
annexed, that is to say :-

page_text: My Invention consists in forming the front rollers used in frames for
drawing and spinning or preparing fibrous material with a groove of L
shape in its periphery, and in placing in the bottom of this groove leather or
other suitable yielding material. The ordinary lower roller or boss works in
the groove and draws the fibrous material through.
Figure 1 represents a pair of front rollers constructed according to this
part of my Invention, one roller being shewn in section.
a, a, are the
rollers, the peripheries of which are formed with a groove b as before
mentioned; c represents the leather or other material placed in this groove;
d, d, are the ordinary lower rollers or bosses; they work in the grooves
against the leather c and draw the fibrous materials through.
b
My Invention further consists in constructing grooves in the peripheries of
the front rollers used in frames for drawing and spinning or preparing fibrous
materials in such manner that leather or other material placed in such grooves
may be securely held therein without any other appliance. This part of
my Invention is represented in Figure 2, which shows one of the front rollers
partly in section. I form at the bottom of the groove 6 at each side and at
right angles thereto another groove e to receive the edge of the leather or
other material c. The width of the leather is greater than that of the first
or outer groove b, and it is partly doubled to allow it to be slipped in.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim,--
First. Forming the front rollers used in frames for drawing and spinning or
preparing fibrous materials with a groove as represented in Figure 1 of the
accompanying Drawings, and placing in this groove leather or other suitable
yielding material, as herein-before described.
Second. Forming the front rollers used in frames for drawing and spinning
or preparing fibrous materials with a compound groove, as represented in
Figure 2 of the accompanying Drawings, to receive leather or other suitable
yielding material, as herein-before described.
In witness, I, the said Frederick Dunch Frost, have hereunto set my
hand and seal, this Sixteenth day of April, One thousand eight hundred
