IMPROVEMENTS IN SPINDLES FOR SPINNING MACHINERY
Year: 1884

page_text: I, JULES DE HEMPTINNE of Ghent in the Kingdom of Belgium, Manufacturer_do
hereby declare the nature of my invention for IMPROVEMENTS IN SPINDLES FOR
SPINNING MACHINERY, to be as follows:-
The object of this invention is to prevent the vibration caused by the working
of the machine being transmitted to the bobbin, and the invention consists in
certain mechanical combinations whereby this object may be attained.
To this end I employ a composite spindle which consists of a spindle proper, the
lower end of which is fixed in a cross bar or rail in any convenient manner.
The upper part of the spindle is made hollow and constitutes a tube to any
convenient depth.
In this tube a rod is placed the diameter of the rod being such that it will enter
freely therein. The play of the rod in the tube is prevented by surrounding the
rod with some suitable material such as cotton thread or wool yarn, and at the
bottom of the tube a small pad of the same material. is placed on which the rod
rests. This mode of isolating the rod in the tube is not however absolutely
necessary, it is only necessary that the rod and the tube should be independent the
one from the other in such a manner that the vibrations of the spindle caused by
the working of the machine be not communicated to the needle.
The rod may if desired be allowed to turn in the spindle, but it is found
preferable to hold it stationary and for this purpose the thread or yarn packing is
proposed.
At the top of the spindle is fixed a ring or washer which supports a second ring
or washer provided on its underside with points which enter holes pierced in the
lower ring.
The upper ring is formed with a rebate the diameter of which is varied
according to requirements. These rings are pierced centrally like the spindle.
The rod passes beyond the rings a distance equal to the height of the bobbin. The
bobbin is pierced in such a manner that the rod passes freely through it and it rests
on the ring.
The spindle passes through a tube which turns in sockets fixed'in a cross bar or
rail by means of pressure screws. At the upper part of this tube is fixed the flyer
the arms of which are turned upwards. The flyer receives motion from the drum
by means of a cord which works in a pulley on the tube.
The spindle which passes freely through the tube without touching has an up
and down movement communicated to it equal to the height of the bobbin and
this movement is given to the cross bar or rail in any convenient manner.
Dated this the 20th day of June 1884.

page_text: I JULES DE HEMPTINNE of Ghent in the Kingdom of Belgium, Manufacturer,
do hereby declare the nature of my invention for IMPROVEMENTS IN SPINDLES
FOR SPINNING MACHINERY and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement:-
The object of this invention is to prevent the vibration caused by the working
of the machine being transmitted to the bobbin, and the invention consists in
certain mechanical combinations whereby this object may be attained.
To this end I employ a composite spindle, which is represented in the drawings
accompanying this specification.
Fig. 1 being a longitudinal section of the composite spindle and
Fig. 2 a similar view of a slight modification thereof.
Figs 3 and 4 show detached in elevation and in section the bobbin carrying rod
with its discs or washers.
The
Gis the spindle proper, which is fixed at its lower end in a cross bar or rail T in
any convenient manner. In the Figure it is by means of the two nuts S S¹.
washers R interposed between the nuts and the rail are preferably made of leather
and are intended the better to isolate the spindle from the rail, or the spindle may
be tubular throughout its entire length, a suitable pad being provided for the
bobbin carrying rod H.
The upper part of the spindle is made hollow and constitutes a tube of any
convenient depth as for instance to the point M.
The rod H is placed in this tube, the diameter of the red being such that it will
enter freely therein. The play of the rod in the tube is prevented by surrounding
the rod with some suitable material, such as cotton thread, or wool yarn, and at
the bottom of the tube a small pad M of the same material is placed, on which the
rod rests. This mode of isolating the rod in the tube is not however absolutely
necessary; it is only necessary that the rod and the tube constitute two bodies
independent the one from the other, in such a manner that the vibrations of the
spindle caused by the working of the machine be not communicated to the rod H.
The rod H may turn in the spindle, but it is found preferable to hold it
stationary by the means hereinafter described with reference to Fig. 2 or in any
other convenient manner.
At the top of the spindle G is fixed a disc or washer I, which supports a second
disc or washer J, provided on its underside with points which enter holes pierced
in the disc I. The disc J has a rebate at V, the diameter of which is varied
according to requirements. These discs are pierced centrally like the spindle.
The rod H passes beyond the disc J a distance equal to the height of the bobbin.
The bobbin is pierced in such a manner that the rod passes freely through it and
it rests on the disc J.
D is a tube which turns in. the sockets B, C fixed in the cross bar or tail T¹ by
means of the clamping screws W.
At the upper part of this tube D is fixed the flyer F, the arms of which are
turned upwards. The flyer receives motion from the drum by means of a cord
which works in the pulley P.

page_text: The spindle G, which passes freely through the tube D without touching it has
an up and down movement communicated to it equal to the height K¹K of the
bobbin, and this movement is given to the cross bar or rail T in any convenient
manner.
The yarn or other material, as it leaves the cylinders is passed through an
eyelet F¹ of the flyer, which turns rapidly, and gives to the yarn the required
twist; the amount of drag put upon the bobbin being regulated by the size of the
washers or discs I and J.
In the modification shown at Fig. 2 the rod H is shorter than in the former case
its length being such that it extends an equal distance above and below the disc
or washer I'. In cases where the friction is not required to vary, a single disc or
washer is sufficient and this disc or washer (I' Fig. 2) instead of being fixed on the
tubular spindle G may be fixed "directly to the rod H, as shown at Fig. 2, but in
this case by having two different diameters to the disc the friction may be varied
with ease by withdrawing the rod H and turning it upside down.
If desired a second disc J¹ may be employed as in the case of the disc fixed to.
the spindle and a leather or other washer 111 may if desired be interposed between
the two discs 11 and J' (see Fig. 4), or the disc J¹ may rest on the disc I' without
the leather or other washer. The same arrangement may be used with the disc
fixed to the spindle G.
In Fig. 2 the mode in which the rod H is fixed in the tubular spindle is slightly
different to the plan first described.
X is a small screwed pin having its lower part surrounded with a packing M¹ of
cotton thread, woollen yarn or other suitable substance which is forced with the pin
to the bottom of the hollow portion of the spindle where it rests on some soft
material. The lower end of the rod H is drilled and tapped as shown at Fig. 3 to
receive the end of the small screwed pin X.
The remaining portion of the rod H below the disc or washer is also surrounded
by cotton thread or woollen yarn which will enter into the tubular spindle as the
rod is drawn gently down by being screwed onto the pin X.
The advantages of this system are:-
1. The isolation and the centreing of the rod H in the tubular spindle.
2. The rod H cannot turn with the bobbin.
3. The rod cannot withdraw from the tubular spindle unless it is unscrewed or
turned in a reverse direction to that of the rotation of the bobbin.
4. The rod H may be made to serve at both ends, its surface always remaining
smooth.
The sockets B and C are also arranged in a slightly different manner and the
tube D rests in a recesso formed in the lower socket, the recess serving as a step
bearing. The lower part of the flyer may also rest on the socket B as in Fig. 1.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1. In a composite spindle for spinning machines, the combination of a hollow
spindle G with the bobbin carrying rod H in such a manner that they shall be
independent of one another, whereby the vibrations of the spindle shall not be
transmitted to the bobbin, substantially as described above and shown in the
drawings.
2. In a composite spindle for spinning machines the combination of the discs or
washers I and J with one another, and with the spindle G and the bobbin K,
whereby the up and down movement is transmitted to the bobbin substantially as
described and shown.
3. In a composite spindle for spinning machines, the combination of the spindle G
with the tube D mounted in the sockets B and C, of the cross bar or rail T'
and carrying at its upper end the flyer F, and receiving movement from the drum

page_text: by a cord acting on the pulley P, the whole substantially as and for the purpose
described.
4. A composite spindle for spinning machines constructed, arranged and
operating substantially as herein described and shown with reference to the
accompanying drawings or any mere modification thereof.
