Manufacturer, for an Invention of "IMPROVEMENTS IN AND CONNECTED
WITH MACHINES FOR SPINNING CARDED WOOL AND OTHER FIBROUS
MATERIALS, ALSO APPLICABLE TO SLUBBING."
COMPLETE SPECIFICATION filed by the said Arnold Munzinger at the Office
of the Commissioners of Patents on the 7th May 1881.
ARNOLD MUNZINGER, of Olten (Soleure), in Switzerland, Manufacturer.
"IMPROVEMENTS IN AND CONNECTED WITH MACHINES FOR SPINNING CARDED
WOOL AND OTHER FIBROUS MATERIALS, ALSO APPLICABLE TO SLUBBING."
My Invention relates to improvements in that class of machinery for spinning
carded wool and other fibrous materials (such for example as worsted yarn), in
which two rollers are together and simultaneously rotated in two directions
(perpendicular to each other), for the purpose of drawing a roving or sliver, and at
the same time twisting it, and the said Invention comprises two different
constructions or arrangements of mechanism hereinafter described, which posses
the following advantages over machines of the same class heretofore constructed,
viz.
1. The spinning is effected in a more regular manner, all the rotating parts being
actuated by toothed gearing.
2. Friction is considerably reduced, and great facility for lubrication of the
working parts is afforded.
3. The pressure exerted by the drawing rollers upon one another can be regulated
as required, and each pair of rollers can be separated to facilitate the introduction
of the rovings or slivers.
4. Each drawing or spinning device can be stopped and re-started at will simul-
taneously with its corresponding spindle, without jerks or shocks, and without
having to stop.the other spindles.
My Invention will be readily understood.on reference to the accompanying
Drawings, in which Figures 1 and 2 (Sheet 1) illustrate the first arrangement or

page_text: construction of my improved machinery for drawing and twisting rovings or
slivers.
Figure 3 (Sheet 1) shows the second arrangement or construction of my improved
drawing and twisting machinery; and Figure 4 (Sheet 1) shews in front view the
arrangement for bringing into and throwing out of gear certain parts, as hereinafter
described.
Figures 5, 6, and 7 (Sheet 2) represent in side view, elevation and plan respec-
tively my improved form of spinning machine, which is provided at the right hand
side with the drawing and twisting device or mechanism such as shown in
Figures 1 and 2, and on the left hand side with the device or mechanism" as shown
in Figures 3 and 4, and serves to illustrate the manner in which these devices are
to be mounted in practice.
The device shown in section in Figure 1, and in under side view in Figure. 2, is
constructed as follows, that is to say:-
A is a crosspiece or bar extending from one end of the machine to the other. It
is composed of two vertical pieces connected together by a pierced horizontal piece,
the form of which is seen in Fig. 2; B and C are two lids or plates, which form,
together with the crosspiece or bar, an upper and a lower compartment for each
spinning device, and serve as bearings for the moving parts of the said devices.
The crosspiece A is also provided with apertures for the wheels 7 and 8, herein-
after more fully referred to.
A disc D has a funnelshaped opening, and is provided with helicoidal teeth; it
rotates freely in the plate B, in which it is retained by another plate E. The disc D
carries the drawing rollers m and n, the former of which is fluted; they are
mounted in bearings J and K. The bearing K is rigidly fixed underneath the
disc D; the bearing J however is only attached to the aforesaid disc by a binge,
and is provided with an extension, which forms a spring and allows of the pressure
exerted by the roller n upon the fluted roller m being regulated by tightening or
loosening the screw ring F.
An extension of the axle of the fluted roller m carries a small bevel wheel H,
which gears into an internal screw thread cut on a ring G; this ring G is placed in
the compartment formed by the plate C and the cross piece A. It is furnished
upon its exterior with helicoidal teeth, which gear into the wheel 7', which either
imparts a slow movement thereto in one or the other direction, or prevents motion
of the same, as may be required.
Upon a shaft SI provide for each spinning device a wheel s, which is either
keyed thereon, or is driven by the same by means of suitable gearing.
Upon another shaft R are keyed wheels r, one for each spinning device, whereby
the movement of the rings G is regulated.
Each of the wheels s gears into one of the discs D, and thus imparts rotary
motion to the rollers m and n, the direction of said motion being in the plane of
the axes of the rollers, and perpendicular to the geometrical axis of the yarn,
whereby the twisting of said yarn is effected. As however the disc D rotates
simultaneously with the rollers m and n, the rotation of the fluted. roller m around
its axis is caused by the bevel wheel H, which is forced to gear with the interior
screw thread on the ring G.
The roller n being pressed against the fluted roller m by the spring bearing J is
set in motion by the lastnamed roller, thus causing the roving or sliver to be drawn,-
the drawing being regulated at will by turning the ring G either forwards or
backwards by means of the wheel r, so as to increase or diminish the speed of the
wheel H.
The yarn on leaving the drawing rollers m and n is wound on to bobbins by
means of any suitable arrangement of spindles.
:
The second construction or arrangement of my improved spinning machinery is
illustrated in Figures 3 and 4 (Sheet I.) It is constructed as follows, viz. :-A
trough shaped crosspiece A extends from one end of the machine to the other,

page_text: and for each spinning device there is a lid or plate B, whereby a box or casing is
formed, in which the ring G is enclosed; this ring has helicoidal teeth upon its
exterior, and a screw thread upon its interior. Motion of the ring G is prevented,
or motion in a forward or backward direction is imparted thereto, by the wheel r.
The spinning device proper consists of the plates C and D, which are rigidly
connected together by means of the rods E, E. The plate D is connected with the
funnel shaped piece D¹ by the arms K, which serve as bearings for the fluted
roller m with the bevel wheel H.
The knee lever J carries at its upper part the roller n., which is pressed against
the fluted roller m by a spring L acting upon the horizontal arm of the knee lever.
By turning the nut M around the sleeve F the pressure of the spring L can be
increased or diminished as required. The sleeve F is also provided with two
apertures corresponding with springs f, f, and is free to slide on these latter when
rotated to a certain extent. By these means the rollers m and n can with great
facility be separated or moved away or from one another, which will be found of
great advantage when a yarn breaks. The two rollers can be brought close
together again with equal facility, and without in any way altering the pressure of
the spring L.
The hub of the plate C swings in the fixed bearing X, and gears by means of
the helicoidal teeth on its periphery with the wheel s. Its rotation is transmitted
to the plate. D, and consequently to the rollers m and n, by means of the rods E, E,
and the whole of this mechanism is guided at its upper part by the lid or plate B,
in which the funnel shaped piece D¹ is pivoted, which latter thus serves as an upper
axle or pivot.
The spindle t is set in motion by the whorl Z; it is pivoted in the step Y, and
is guided by the sleeve Q, this latter being raised and lowered at the same time as
the rail P.
N and W are clutches, by means of which each spinning device, together with
the spindle corresponding thereto, can be thrown into or out of gear.
The whorl Z rotates freely on the spindle t, the wheel s being mounted in like
manner on the shaft S. Each of these parts carries at top a hollow cylindrical
part or piece, having a projection with bevel sides. The clutches N and W are
connected with the spindle t and shaft S by means of sliding pieces, and are
actuated by the whorl Z and wheels when the springs h and take into the
interior projections of the whorl Z and wheel s.
This arrangement has for object to enable the throwing into and out of gear to
be effected easily, and without jerks or shocks; but instead of the springs h, h, and
v, v, simple frictional surfaces may be employed.
The simultaneous throwing into and out of gear of the clutches N and W is
effected by raising or lowering the lever g keyed on the axle a, which also carries a
fork i.
The winding upon a bobbin may be effected by any of the wellknown means, by
utilizing on the one hand the rotation of the spindle t, and on the other the rising
and falling movements of the sleeve Q.
Figures 3 and 4 illustrate by way of example the following construction of
gearing for this purpose:-
The bobbin T is fixed upon the spindle t; upon a ring U rigidly connected with
the sleeve by small rods V, V, a double hook W moves freely.
Upon leaving the drawing rollers m and n the yarn passes through this book W,
and is wound upon the rotating bobbin T.
In Sheet 2 a spinning frame or machine of special form is represented having
both arrangements or constructions of spinning devices, herein described, and
shown applied thereto. This frame is of a very advantageous form for mounting
thereon either both arrangements of spiuning devices or two devices of the same
form. When two spindles only are to be worked these devices can be easily
mounted in said frame, and occupy but little space.

page_text: Motion is imparted by the main driving shaft Y; the wheel 1-keyed thereon
transmits motion to the wheel 11 by. means of a change wheel 8. The former
transmits motion to the shaft S, which carries the worm wheels, which actuates
the rotating disc D carrying the drawing rollers m and n.
By means of the wheels 9 and 10 the wheel 1 likewise regulates the movement
of the shaft R, and consequently that of the ring G.
At the left hand side, wheel i actuates the shaft S by means of the wheels and
5, the wheels sets in motion the parts C and D, that is to say, the spinning device
proper, whilst the wheel r regulates, by means of the intermediate wheels 2 and 3,
the movement of the ring G.
From the drum or pulley X belts, straps, or cords pass to the right and left, which
cause the whorl Z to rotate.
A heart shaped eccentric 18 causes the bobbin T at the right hand side, and also
the ring U at the left hand side, to rise and descend by means of the lever a, rod b,
and two armed lever c.
Upon the shaft Y is keyed the chain wheel 12, which imparts motion to the
wheels 13, 13, and 14 by means of an endless chain 20. The wheels 13, 13, operate
the drawing rollers, as shewn in the elevation.
Wheel 14 gears with wheel 15, and actuates the drum 17 by means of
wheel 16 and eccentric 18.
The machines herein described may also be employed for slubbing, as will be
well understood.
Having now described the nature of my said Invention, and in what manner
the same may be performed, I declare that I claim,-
