page_text: LETTERS PATENT to François Vennin Derégniaux, of Lille, in the Empire
of France, Machine Maker, for the Invention of "IMPROVEMENTS IN THE
CONSTRUCTION OF SPINNING MACHINERY."
CONSTRUCTION OF SPINNING MACHINERY."
Sealed the 20th November 1855, and dated the 26th June 1855.
PROVISIONAL SPECIFICATION left by the said François Vennin Derégniaux
at the Office of the Commissioners of Patents, with his Petition, on the
26th June 1855.
I, FRANÇOIS VENNIN DERÉGNIAUX, of Lille, in the Empire of France,
Machine Maker, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN THE CONSTRUCTION OF SPINNING MACHINERY" to be as
follows:-
The object of this Invention is to equalize the pressure upon the presser
rollers of spinning frames, and at the same time by leaving the lines of
rollers more open to facilitate the piecing of the broken threads. To this
end I substitute presser bars for the hinged presser levers, and I either
use separate bars with a pressing edge for the upper and lower rollers, or.
I cause the same bars to press against both rows of rollers. These bars I-
attach to the spinning frame, in such a manner that they may move up

page_text: towards the rollers in a parallel line, instead of moving in the are of a circle
when pressed forwards by the weighted rods, which latter movement induces
an unequal amount of pressure to the upper, and lower rollers. The vertical
adjustment of the rollers when the same presser bars press on the upper and
lower rollers, I provide for by means of vertical regulating screws which pass
through lugs on the bracket bearings, and enter tapped holes in the tail of the
sliding bushes which carry the upper rollers.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said François Vennin Deregniaux, in the Great Seal Patent
Office on the 24th December 1855.---
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FRANÇOIS
VENNIN DEREGNIAUX, of Lille,-in-the-Empire of France, Machine Maker,
send greeting.
WHEREAS Her-most Excellent, Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-sixth day of June, in the year of our Lord
One thousand eight hundred and fifty-five, in the nineteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said François Vennin Deregniaux, Her special license that I; the said
François Vennin Deregniaux, my executors, administrators, and assigns, or
such others as I, the said-François-Vennin Deregniaux, my executors,
adñiors, 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 THE CONSTRUCTION OF SPINNING
MACHINERY," upon the condition (amongst others) that I, the said François
Vennin Deregniaux, by an instrument in writing. under my hand and seal,
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 Seál Patent Office within six calendar months next
and immediately after the date of the said Letters Patent..

NOW KNOW YE, that I; the said François Vennin Deregniaux, do hereby.
declare the nature of my 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 Drawings hereunto annexed,
and to the letters and figures marked thereon (that is to say.)

page_text: The object of this Invention is to equalize. the pressure upon the presser
rollers of spinning frames, and at the same time by leaving the lines of rollers
more open than heretofore to facilitate the piecing of the broken threads. To
this end I substitute presser bars for the hinged presser levers, and I either
use separate bars with a pressing edge for the upper and lower rollers, or
I cause the same bars to press against both rows of rollers. These bars I
attach to the spinning frame, in such a manner that they may be moved up
towards the rollers or pressed forward in a straight or direct line instead of
being moved in the arc of a circle, as has usually been the case heretofore
when levers are pressed or drawn forward by weighted rods. The great dis-
advantage of causing the pressure to act in the direction of the arc of a circle
is, that this movement imparts an unequal amount of pressure to the upper
and lower rollers, and furthermore, the pressure will constantly vary as the
Follers wear away, whereas by causing the pressure to act in a straight line it
can never vary in. amount while the weight remains the same.
The vertical
adjustment of the rollers wlien the same presser: bars press on the upper and
Tower rollers I provide for, by means of immoveable pieces which may be moved
vertically by means of adjusting 'screws which pass through lugs on the
bracket bearings, and enter tapped holes in the tail of the sliding bushes which
carry the upper rollers, or by movable pieces which may be fixed at any point
by means of set screws.
In the accompanying Drawings I have shewn various views of different
methods of carrying out my Invention or system of imparting pressure in
right or straight lines to the rollers.
Fig 1, Sheet I, is a side elevation of one method of effecting this object;
Fig. 3 is a plan view of 'the same, shewing the mode of mounting the lower.
presser roller; Fig. 6 is a sectional view takeii in the line a; a,.of Fig. 1;.
Fig. 2 is a side elevation, and Fig. 4 a plan view, shewing the method of
mounting the upper pressing roller; Fig. 7 is an end or front view of the:
supporting arm. These Figures 1, 2, 3, 4, 5, 6, and 7, are drawn the full.
size of the working parts. Fig. 8, which is drawn to a scale of half the real;
size, represents in elevation the parts (shewn separately in Figs. 1 and 2),
combined together, as they would appear in the machine when at work.
aa is the front bar of the frame of the spinning machine, and to which the
supporting arms b, b, and c, c, of the presser rollers are attached by screws of
bolts; or in any other convenient manner; b, b, is the supporting aim of the
lower presser roller d; and c, c, is the supporting arm of the upper presser
roller e. The axles of the presser rollers-d and e, are carried by bearings, at
the end of the sliding pins f and g, which pass through holes-at the ends.of.

page_text: the supporting arms b and c, and bear against the angle pieces h and i.
Screwed rods j and k, with nuts thereon, pass through holes made in the
pieces and i, and extend back behind the front bar a of the spinning frame,
and being weighted at their inner ends, these rods j and k will by means of
the angle pieces h and i, and the pins and bearings f and g, press forward
the presser rollers d and e in a direct or straight line as indicated by the
blue lines in the Figures against the front rollers which are mounted on the
front bar of the spinning frame.
Fig. 9, Sheet II., is a side elevation, and Fig. 10 a front or end view, of
a modification of the plan shewn in Sheet I. In this instance there is only
one supporting arm b, b, to which the bearings ƒ and g of the upper and
lower pressing rollers are both adapted, instead of having separate support-
ing arms for each pressing roller, as in the former instance; b, b, is the
supporting arm having at its outer end a cross piece provided with a round
hole at the lower end through which is passed the spindle f, of the bearing
which carries the pressing roller d. A long slot i (Fig. 10) is made in the
upper part of the cross head of the supporting arm, for the purpose of
receiving the shank g of the upper pressing roller e.
This shank g passes
through a socket 7, to which a set screw m is adapted, so that the socket and
shank g, with the upper pressing roller e, may be set or fixed at any convenient
point on the cross head of the supporting arm.
It will be seen that the spindle f and shank g are allowed to move freely
in their sockets in parallel lines, so that the pressing rollers may be forced
against the other rollers with a constant pressure. This pressure is given by
means of the screwed spindle j, as in the Figures in Sheet I., but in this
instance the screwed spindle ; passes- through a hole in the bar h, which is
made to bear against the ends of the spindle f and shank g, and thus force
the pressing rollers d and e in direct and parallel lines against their fellow
rollers d and e, as indicated by the blue lines in Fig. 9. As the screwed
spindle fits loosely in the hole in the cross piece h, this piece-is-capable-of-a-
slight rocking motion, which will admit of the piece / adjusting itself to its
work, and pressing with equal force on the spindle and shank of the two
pressing rollers & and e.
Any person acquainted with spinning machinery will see at once that by
the arrangement and construction of parts above described, great facility is
given to the attendant to get at the threads or yarns when required to piece or
mend broken threads, whereas in the arrangements usually employed the
rollers are to a great extent. covered up, and great difficulty is experienced in.
getting at them.

page_text: Having now described my Invention of "Improvements in the Construction
of Spinning Machinery," and the best means with which I am acquainted
for carrying the same into effect, I would observe, in conclusion, that I do not
mean or intend to confine myself rigidly to the precise arrangement of parts
herein shewn and described, as they may doubtless be varied without depart-
ing from the nature and object of my Invention; nor do I intend to claim the
application of a double pressure to the rollers of spinning machinery; but
that which I consider to be new in the above-described improvements, and
therefore wish to claim as the Invention secured to me by Letters Patent as
aforesaid, is, imparting pressure to the pressing rollers by means of presser
bars acting in straight or right or parallel lines, or in a direct line to the
centre of the rollers, in contradistinction to curved lines as heretofore, so that
the pressure on the rollers of the spinning frame may be always constant and
unvarying, whatever may be the diameter of the said rollers, or however they
may vary in diameter by wear or otherwise.
In witness whereof, I, the said François Venuin Deregniaux, have
hereunto set my hand and seal, the Fifteenth day of December, in
the year of our Lord One thousand eight hundred and fifty-five.
