ARNOLD MUNZINGER, of Olten, in the Canton of Soleure, in Switzerland,
Manufacturer. "IMPROVEMENTS IN AND CONNECTED WITH SPINNING-MACHINES."
My Invention relates to improvements in and connected with spinning machines,
and has for object to obtain the following advantages in such machines.
1st. The rapid and ready change of the machine for either spinning raw
materials of different qualities, or for obtaining different degrees of tension and of
twist.
2nd. Perfect uniformity of tension and twist, by employing for all the
movements suitable gearing, as hereinafter described.
3rd. Saving of space and time by dispensing with the carriage of the selfactors.
4th. Great simplicity of the machine by which the working is rendered. easy,
and by which frequent repairs are obviated, such simplicity permitting at the same
time the use of the machine in establishments where small quantities are often
spun, and where the work on the same machine frequently requires to be varied.
5th. Rendering the yarn less liable to breaks, it not having any eye to pass
through; besides which, these breaks can be as quickly repaired as in the self-
actors.
6th. Effecting the spinning with great evenness, and to any degree of fineness,
and
7th. The use of the machine for slubbing and roving, and its application to the
manufacture of clouded yarns (chinés).
The apparatus constituting my Invention, of which there is one for each spindle,
is mounted in the spinning machine, and consists of a set or system of two drawing
rollers possessing a double rotation, one such rotation being around their respective
axes, and the other in the plane of their axis around an axis perpendicular to such
plane. One of these rollers is toothed or fluted, and the other is faced with felt, leather,
or other suitable material, as in ordinary spinning machines; they are supported
in a disc or socket provided with a funnel shaped opening or other convenient
opening. The toothed or fluted roller is mounted in a fixed bearing, and the faced
oller, which is in a moveable bearing, is pressed against it by a spring, and is

roller carries at one of its ends a bevil pinion of special form, which gears with an
internally screw-threaded ring, herein after fully described. The disc or socket
aforesaid is fitted into a frame or plate in which it revolves; it is toothed on its
circumference and gears with a wheel; the ring is also toothed, and gears with
another wheel.
To better understand the working of my improved spinning-machine, I first
proceed to describe the working parts of same, and then the working of one of the
apparatus above described.
On the main driving shaft of the machine a wheel is keyed, which by means of 1
a change wheel and another wheel imparts a rotatory motion to the shaft carrying
the wheel in gear with the disc or socket. A second wheel, also keyed on the
main dring shaft, gears with another change wheel. A double pinion, free to
revolve on the shaft carrying the wheel in gear with the disc or socket, gears on
one side with the second change wheel, and on the other with a third change
wheel, to which it transmits the movement from the second change wheel. This
last named wheel is in gear with a pinion which drives the shaft carrying the
wheel in gear with the toothed ring.
The main driving shaft also carries a pinion, which, through a suitable train of
wheels, sets in motion the fixed upper drawing rollers, the shaft of which, through
other suitable gearing, transmits motion to the cylinder over which is placed the
slub. The first mentioned keyed wheel on the main driving shaft also drives by
means of other wheels the drum or cylinder actuating the spindles.
The slub on being unwound passes between the fixed upper drawing rollers, and
thence between the doubly rotating ones hereinbefore described, and on to a spindle
on which it is wound, and which gives it the requisite amount of twist.
Between the fixed upper drawing rollers and the doubly rotating ones the yarn
receives, 1st, a perfectly uniform tension without jerks, the degree of which can be
varied with the greatest ease by simply changing a change wheel; and 2ndly, a
twist always in the same direction capable of being easily increased or diminished.
The working of one apparatus with the doubly rotating rollers is as follows:-
The rotation of the shaft carrying the wheel in gear with the disc or socket
imparts rotary motion to the said disc or socket, and consequently to the drawing
rollers rotating as above described.
The specially formed bevil wheel gearing with the screw threaded ring will
receive from it a rotary movement. Accordingly as this movement is increased or
decreased, the yarn will receive a greater or lesser tension. If therefore the said
ring be caused to revolve in either direction by means of the wheel in gear with it,
this movement necessarily having the effect of quickening or lessening the rotation
of the bevil wheel, will increase or reduce the tension given to the yarn.
By changing the third change wheel, the speed of the drawing rollers, and
consequently the tension given to the yarn, can be varied.
And further, by substituting a larger or smaller wheel for the central one of the
train driving the fixed upper rollers, the speed of the disc or socket, and consequently
the twist of the yarn, can be varied; thus it will be readily understood that by
means of this arrangement the extreme limit of fineness of the yarn can be
attained, besides which the machine can be arranged for all kinds of work with
the greatest ease.
