page_text: LETTERS PATENT to Samuel Dreyfous, of Paris, France, Civil Engineer,
for the Invention of "AN IMPROVED THROSTLE SPINNING FRAME."-A
communication from Monsieur Charles Leyherr, residing at Lava',
France.
Sealed the 15th July 1862, and dated the 18th January 1862.
PROVISIONAL SPECIFICATION left by the said Samuel Dreyfous at the
Office of the Commissioners of Patents, with his Petition, on the 18th
January 1862.
I, SAMUEL DREYFOUS, of Paris, France, Civil Engineer, do hereby declare
the nature of the said Invention for "AN IMPROVED THROSTLE SPINNING FRAME,"
that it is a commuication from Monsieur Charles Leyherr, a person resident
at Laval, France, to be as follows:-
The object of this throstle spinning frame is to do away with the principal
defects of the ordinary throstle frames, this improved one allowing, 1ly, pro-
ducing conical-shaped cops as well as the ordinary ones; 2ly, working at
much greater speed than with the ordinary throstle frames; 3ly, spinning any
description or fineness of yarn as well as twist or warp, as for semi-warp
and weft.
In the annexed Drawings Fig. 1 shows a side elevation, and Fig. 2 a
vertical cross sectional view of the machine for the roving, bobbins C and
the rollers B for drawing the rovings or thread on to the cop spindles D, the
flyers of which latter are mounted. Corresponding parts are indicated by the
same letters of reference.
The machine consists of a suitable frame A, provided on one or both sides
with the well known arrangements for the roving bobbins C, and the sets of
rollers B for drawing the rovings on to the cop spindles D, the flyers of which

page_text: are mounted in the bars E. Each flyer consists of two rings or bosses e and e'
fixed parallel to each other by means of two rods f and a cross bar 9. this
latter provided with guide eyelets for the roving to pass through, the said
roving being further slung round one of the rods f and passed through another
eyelet d¹ before winding on the cop tube. The lower ring e has a whirl i for
transmitting the motion from a barrel F to the flyers, which latter turn by
means of their upper rings e¹ in fixed collars e². The spindles are situated on
the copping beam G, the vertical up-and-down motion of which is obtained by
means of an arm H' turning on a fixed axis H, the other end of which arm
carries a toothed sector H2 in gear with a pinion H³, in the arbor I of which
are fitted also two other pinions I' in gear with two vertical rack J fixed to
the copping beam G; the ascending motion of this beam is produced by means
of two counterweights G¹ (one of them at each end of the beam), while
another counterweight G2 is connected with the upper end of the sector H,
and cause this latter to rise; on the axis H also turns a forked arm L, provided
with a curved projecting finger L³, the free end of which has a friction roller L
acted upon by a scroll M, on the axis m of which is fixed a worm wheel M¹
in gear with the endless screw M² with which the arbor M³ is provided; this
arbor M³ being connected by the conical wheels M* to the arbor of the flyer
driving barrel; in the slit n of the forked arm L works a screw N, the nut N'
of which glides in the slit n, and is fixed to a presser plate O, the side O³ of
which works against a stud 02 fixed to the sector arm H³; to one end of the
screw N is fixed a spur wheel P, in which takes a pawl P¹ provided with a
counterweight P²; by this arrangement the plate O will be obliged to travel
with an intermittent motion along the threaded part of the screw N, the plate
advancing towards the spur wheel P at each descending motion of the copping
beam G, whilst the sector H2 and the scroll M will mutually cause each other
to rise or fall according as required. In order to allow the required increasing
and decreasing of the friction exerted on the spindles by the weighted strings q
to take place according as required; these strings have their counterweights
hung over a bar or rod r, which latter by a suitable arrangement is governed
by a heart wheel Ŕ fixed on the scroll arbor m.
SPECIFICATION. in pursuance of the conditions of the Letters Patent, filed
by the said Samuel Dreyfous in the Great Seal Patent Office on the
18th July 1862.

Patent, bearing date the Eighteenth day of January, in the year of our
Lord One thousand eight hundred and sixty-two, in the twenty-fifth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Samuel Dreyfous, Her special licence that I, the said Samuel
Dreyfous, my executors, administrators, and assigns, or such others as I, the
said Samuel Dreyfous, 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 " AN
IMPROVED THROSTLE SPINNING FRAME," a communication to me from Monsieur
Charles Leyherr, a person resident at Laval, France, upon the condition
(amongst others) that I, the said Samuel Dreyfous, 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 Office within six'
calendar months next and immediately after the date of the said Letters
Patent.
. NOW KNOW YE, that I, the said Samuel Dreyfous, do hereby declare
the nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
For spinning cotton or other filamentous materials by means of what are
called throstle spinning frames, a great number of mechanical arrangements.
have been devised for communicating in a continuous manner the required
degree of twist or torsion to the yarn, and simultaneously winding the same.
upon the spindles or the bobbins; for a great many purposes mule spinning:
has continued to be preferred.
The object of the present Invention is to offer a throstle spinning frame.
doing away with the defects such machines hitherto presented, and allow of
spinning by means of them, as well warp, semi-warp, and weft, either for:
coarse or for finer descriptions of goods.
In the annexed Drawings, Fig. 1 represents a side elevation view of my
improved throstle frame, of which the Fig. 2 and 3 respectively show a
longitudinal front and a transverse sectional view, whilst the Fig. 4 represents
a plan view of separate parts of the frame. In these Figures corresponding
parts.are marked by the same letters of reference...

page_text: As in throstle frames generally, this improved frame may be double or
simple, that is to say, be provided on one or on both sides with the required.
arrangements for drawing, twisting, and winding, both sides working indepen-
dently of each other, though receiving motion from the same prime mover.
In order to make the Invention less complicated, and consequently easier
understood; in the annexed Drawings a frame provided with spindles, flyers,
drawing rollers, and so on, on one side only is represented.
Round the lower ring of the flyer is
whorl g, receiving motion from the
This arrangement prevents the flyer
This improved throstle frame consists of two end standards or uprights a, a¹,
and two intermediate ones b, b', situated parallel to each other, and held
together by suitable cross tie pieces. A metal cross-bar c is fixed to and
extends for the entire distance between the standards a, a¹, and serves as a rest:
for the flyers d, allowing these latter to revolve freely in a suitably lubricated.
circular groove in a fixed collar c¹. Each flyer d consists of an upper ring d',.
and a lower one d kept parallel to each other by means of two rods e and e¹,
connected at the top by a cross tie f¹, provided at the centre with a guide hook
or eyelet f for the yarn to pass through.
fixed a small grooved driving pulley or
drum h by means of the endless string i.
from deviating from the vertical position whilst rotating; the upper ring d¹ of
the flyer revolves freely in a collar k fixed to the angle iron k¹ of the frame.
In the centre of each flyer revolves a vertical spindle 7, whilst the entire series
of spindles rests on a copping rail m, the vertical up-and-down motion
imparted to which rail causes the regular winding of the yarn upon the spindles
or upon the bobbins, with which these latter are provided to take place, which
up-and-down motion is transmitted to the said rail m by the following
mechanism: An arm o provided at one end with a toothed sector o' turns at the
other end on an arbor n, and thus causes a pinion p, in gear with the sector o³ to.
turn in one direction when the arm o is rising, and in the opposite direction when
this arm performs its downward motion. On the arbor p¹ of the pinion p are
situated two similar pinions q and q¹ respectively in gear with the racks 'r and r¹
fixed to the copping rail m, thus compelling this latter to follow the alternate
up-and-down motion of the said racks. As may further be observed from
Fig. 1, the ascensional motion of the rail m takes place by the effect of the
counterweights s, and that of the arm o by the effect of the counterweight s²,
the strings of which counterweights s and s¹ passing over suitable guide pulleys,
and having their other ends respectively fixed to the copping rail m, and to the
upper end of the sector o¹. Round the arbor n of the arm o turns another.
arm u situated parallel to the first one, and provided with a longitudinal slot u²,
in which a screw nut v¹ may glide forward and backward by the effect of the

page_text: screw t, the blank ends of which screw turn in collars or bearings provided in
the arm at both ends of the slot u', and thus causes a presser plate v fixed to
this nut to travel forward and backward over the full length of the screw t
with an intermittent motion, viz., so that the presser plate v is caused to
advance when the rail m descends, the nut v being compelled to traverse along
the screw t, the latter turning by the effect of a ratchet wheel & fixed to one
end of the blank of the screw, and the clink y acting by means of its counter-
weight y'. As may be observed in Fig. 1, the presser plate acts with its
side w, w', w³, against a stud fixed to the sector arm o, which renders the
motions of this arm, and those of the arm u, dependant of each other; the part
w, w', of the side w, w', w², of the presser plate v, forms a straight line, and
that w', w, a curved one; when the winding on begins the upper end of this
curved part w, w³, presses against the stud 2. At each time the copping
rail m performs its downward motion the screw nut v¹, and the presser plate v,
are compelled by the effect of the ratchet wheel turning for one tooth to
advance towards the arbor n, and during the time the curved part w³, w³, presses
against the studs, the lower part of a cop or bobbin is formed, whilst imme-.
diately when the straight part w, w¹, begins to act on the stud the winding of
the body of the cop or bobbin commences, which body will be finished as soon
as the plate v ceases to act on the stud, after which the pointed end of the cop
is formed by itself. The end of the arbor of the drum h, by means of the
bevil gear- h', transmits the revolving motion of this drum to the vertical shaft
h2, the lower part of which is provided with a worm h³, in gear with a large
worm wheel 3, on the shaft of which is fixed a scroll 2, acting against a friction
roller 1 turning on a stud fixed in the end of a finger or projecting part u³, of
the slotted arm u, in such manner that the motions of the scroll 2, and of the
drum h, and consequently of the flyers d, connected thereto, and those of the
arms u and o, and consequently of the copping rail m, and the spindles 7, will
reciprocally be entirely dependant of each other. A series of small strings 4,
each of them provided with a small weight 5, serve for increasing or decreasing,
according as required, the friction exerted on the spindles 1, (the latter being
dragged round by the yarn delivered out from the revolving flyers) which strings
4 act simultaneously by the effect of the horizontal to-and-fro motion imparted
to a longitudinal rod 6, over which the said strings are hung, and are thereby
caused to press more or less intensely against a boss ³, towards the lower end
of each spindle. The to-and-fro motion is imparted to the rod 6, by means
of a lever 7, having its fulcrum in 8, in the slotted end of which lever works
a stud 12 fixed to the end of the rod 6, the other end of the lever being pro-
vided with a friction roller acted upon by the cam roller or side excentricum
:

page_text: 10. In Fig. 3 is shown the mode in which the yarn, after leaving the draw-
ing rollers passes through the eylet f, is slung twice round the rod e, and from
thence winds itself upon the spindle 7. The crossing of the yarn takes place
while the spindles are rising, as also the friction of the weighted strings 5, on
these latter.
I finally wish to add here that this improved throstle frame allows, 1ly, to
wind the yarn as well into cops as on bobbins; 2ly, to work with about the
same speed as in mule spinning,.or. with self-acting frames, and consequently
much quicker than with the throstle frames hitherto in use; 3ly, to spin equally
advantageously any description and fineness of yarn, such, for instance, as
warp or water twist, semi-warp and weft, either for coarse or heavy goods, or
for finer fabrics.
Having thus described and particularly ascertained the nature of the
Invention and the manner in which the same is or may be put into effect,
I declare that what I consider to be novel and original, and therefore claim
as the Invention secured to me by the herein-before in part recited Letters
Patent is,
1ly, the mechanical combination in general of the various part of this,
improved throstle spinning frame.
2ly, the peculiar arrangement of the flyers, and the above-described mecha-
nical means for imparting to the spindles a quick revolving, and, simultaneously
with it, the up-and-down motion necessary for giving the yarn the required
twist, and causing the same to be wound upon the spindles into cops or on
bobbins..
In witness whereof, I, the said Samuel Dreyfous, have hereunto set my.
hand and seal, this Fourteenth day of July, One thousand eight hun-
