IMPROVEMENTS IN SUPPORTING APPARATUS FOR THE ROLLERS OF SPINNING FRAMES
Year: 1870

page_text: LETTERS PATENT to William Robert Lake, of the "International
Patent Office," Southampton Buildings, London, Consulting En-
gineer, for the Invention of "IMPROVEMENTS IN SUPPORTING APPARATUS
FOR THE ROLLERS OF SPINNING FRAMES."-A communication from abroad
by Florentin Augustin Steverlynck-Delecroix, Edmond Steverlynck,
and Léon Steverlynck, all of Paris, in the Empire of France,
Spinners.
PROVISIONAL SPECIFICATION left by the said William Robert Lake
at the Office of the Commissioners of Patents, with his Petition,
on the 24th May 1870.
I, WILLIAM ROBERT LAKE, of the "International Patent Office,"
Southampton Buildings, London, Consulting Engineer, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN SUPPORTING
APPARATUS FOR THE ROLLERS OF SPINNING FRAMES," a communication, to be
as follows:-
The apparatus which forms the subject of the present Invention is
destined to replace and to modify the bearers as well as the saddles now

page_text: in use in spinning mills for drawing textile substances of all kinds.
From its simplicity this improved supporting apparatus is very easily
constructed, not being in any way solidly attached to the adjacent
support which is altogether independent of it in its movements, it allows
a perfect parallelism to be obtained between the pressure rolls and the
cylinders.
The curtailment of the axis of the saddle, which according to this
Invention does not require to extend beyond the sides of the frame or
support because of the proximity of the two points of support has
the advantage of allowing a considerable augmentation of the
diameter of the drawing rolls without in any way impeding their
rotation. Consequently the following improved results are obtained by
this Invention.
First. Greater ease in working for the operative by the isolation of
the rolls, which allows the sliver to be passed in a more convenient
manner, and consequently deminishes the danger of the work in this
operation, and at the same time simplifies the tying up which is necessary
when the thread breaks.
Second. A greater production and a great diminution of waste by the
variable augmentation of the drawing rollers.
Third. A material reduction of the motive power required by the sup-
pression of the friction heretofore occasioned by the old method of
construction at the extremities of the axes of the two pressure drawing
and feed rolls in the bearings.
Besides the aforesaid advantages my improved guide frame and the
herein described modifications in the saddle render the machine lighter,
more easily mounted and less costly.

page_text: The apparatus is composed first of a frame which has two side pieces b, b¹,
Figure 4, formed with oval upper extremities and connected together by
a bridge P arched in such a manner as to permit the free movement of
the draw rod T (see Figure 3) which participates in the movements of
the swing beam or lever to which it is connected; second, of a guide
way c which is formed at the upper part of the pieces b, b, and is
designed to guide the axle A of the saddle, and consequently the rolls,
in its normal plane at the plane of the entire machine; third, of a
square base Q having two holes with screw threads, and furnished with
two small pins g, the whole serving to hold the frame against the
carrier upon which it is placed in such a manner as to lie between two
of the rollers of the cylinders.
The modification of the saddle consists simply in the shortening of
the axis A at the two sides, Figure 5, in such a manner that being plaeed
in the guide way these two ends of the axis A will not extend beyond
the exterior sides of the flat oval parts of the side pieces of the frame
or support. The shafts of the pressure rolls are made with a boss at
each side of the bearings R, R³, Figure 1, so as to prevent the to-and-fro
movements which are produced in the old method of construction, and
which are always injurious to the working.
As the dimensions may be increased or diminished according to cir-
cumstances my apparatus may be adapted to any frame by removing the
enindles
SPECIFICATION in pursuance of the conditions of the Letters Patent,.
filed by the said William Robert Lake in the Great Seal Patent
Office on the 19th November 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
ROBERT LAKE, of the International Patent Office," Southampton
66
Buildings, London, Consulting Engineer, send greeting:
WHEREAS Her most Excellent Majesty Queen Victoria, by. Her
Letters Patent, bearing date the Twenty-fourth day of May, in the year
of our Lord One thousand eight hundred and seventy, in the thirty-third
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said William Robert Lake, Her special licence that
I, the said William Robert Lake, my executors, administrators, and

page_text: assigns, or such others as I, the said William Robert Lake, my executors,
administrators, and 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
SUPPORTING APPARATUS FOR THE ROLLERS OF SPINNING FRAMES," a communi-
cation to me from abroad by Florentin Augustin Steverlynck-Delecroix,
Edmond Steverlynck, and Léon Steverlynck, all of Paris, in the Empire
of France, Spinners, upon the condition (amongst others) that I, the said
William Robert Lake, my executors or administrators, by an instrument
in writing under my, or their, or one of their hands and seals, should par-
ticularly 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 Office within six calendar months next
and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said William Robert Lake, 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, reference being had to the accompanying
Drawing forming a part of this Specification :-
The apparatus which forms the subject of the present Invention is
destined to replace and to modify the bearers as well as the saddles
now in use in spinning mills for drawing textile substances of all kinds.
From its simplicity this improved supporting apparatus is very easily
constructed not being in any way solidily attached to the adjacent sup-
port, which is altogether independent of it in its movements, it allows a
perfect parallelism to be obtained between the pressure rolls and the
cylinders.
The curtailment of the axis of the saddle, which, according to
this Invention does not require to extend beyond the sides of the
frame or support because of the proximity of the two points of support
has the advantage of allowing a considerable augmentation of the
diameter of the drawing rolls without in any way impeding their
rotation. Consequently the following improved results are obtained by
this Invention.
First. Greater ease in working for the operative by the isolation of
the rolls, which allows the roving to be passed in a more convenient

page_text: placed in the guide way the two ends of the axis A will not extend
beyond the exterior sides of the flat oval parts of the side pieces of
the new supporting frame. The shafts of the pressure rolls are made
with a boss at each side of the bearings R, R', Figure 1, so as to prevent
the to-and-fro movements which are produced in the old method of
construction and which are always injurious in working.
As the dimensions may be increased or diminished according to
circumstances my apparatus may be adapted to any spinning frame by
removing the spindles, whether the said apparatus is formed of cast iron,
copper, or any other suitable metal.
Having thus fully described the said Invention as communicated to
me by my foreign correspondents I wish it understood that I claim
the supporting guide for spinning frames substantially as set forth and
represented.
In witness, whereof I, the said William Robert Lake, have here-
unto set my hand and seal, this Nineteenth day of November,
in the year of our Lord One thousand eight hundred and seventy.
Witness,
E. C. JACKSON.
WILLIAM ROBERT LAKE. (L.S.)
