Improvements in Mounting and Driving Spindles of Continuous
Spinning Machines.
We JULES DÉSIRÉ RYO, ALPHONSE MARIE RYO, and HECTOR RYO, all of
Roubaix (Nord) France, Machine Builders, do hereby declare the nature of this
invention to be as follows:-
The spindles of continuous spinning machines are usually driven either by means.
of bands or toothed gearing.
The disadvantages of the first method are:-1st. Irregular velocity of the
spindles in consequence either of slip of the cord upon the wharve or drum, or of
stretching of the cord; 2nd. Wear of the drums due to the slip of the cord, which
continues to travel after the spindle driving mechanism has been thrown out of
gear; 3rd. Friction of the spindle in its bearings due to the pull of the cord.
With the view of avoiding the above objections, toothed gearing has been
employed but this mode of driving spindles does not allow of attaining, in practice,
a speed of more than four to five thousand revolutions, and causes vibrations which
necessitate the frequent renewal of the collars, renders lubrication difficult and
costly, and is not adapted to all kinds of spindles.
Our improved method of mounting and driving spindles possesses all the
advantages, and none of the disadvantages, of the above methods.
According to our invention, the footstep, or the entire spindle, is made movable
in the horizontal direction for the purpose of putting the spindle in, or out of,
operation, the spindle being driven preferably by means of a friction disc. The
spindle rests freely and constantly in its footstep and the regularity of its motion is
unaffected by the variations in the weight of the cop and it may be driven at a
higher speed than is possible with toothed gear. The spindle can be instantly
stopped with all the parts connected therewith and the effects of vibration are also
prevented by the use of a special bolster bearing.
The invention is also applicable to spindles provided with an oil reservoir
of the kind known as Rabbeth spindles which could hitherto only be driven by
bands.
Reference is to be had to the accompanying drawings, forming part of this
Specification, which shew the improvements applied to two different types of
spindles, but it will be understood that the invention is independent of construction
in so far as it is variable according to the kind of machine or spindle employed.
Figure 1 is a sectional elevation, representing the improvements applied to a spindle
mounted in a bolster and foot-step bearing, and Figures 2 and 3 are an elevation
and plan, illustrating their application to a Rabbeth spindle.
The spindle is in each case mounted upon a horizontally moving part, preferably
a lever & oscillating upon a centre c, as shewn in full and dotted lines in Figure 3.
In Figure 1, the footstep bearing d is carried on the lever b, while in Figure 2 it
is secured to the lever by a nut e or otherwise. In each case the spindle has a
leather collar and is driven by a friction disc g with which collar is brought
into frictional contact by a slight movement of lever b in the direction of the arrow
(Figure 3) by moving the lever b in the opposite direction the contact off with g
is broken and the motion of the spindle may be instantly arrested. The same
result might be produced by slightly shifting disc g. It will be seen that only a
very slight movement of the lever b is required owing to the nearness of the
centre c to the spindle axis, the motion being limited by a fixed stud / received in
a slot i or vice versa. The contact of ƒ and g may be maintained by the pressure of
a spring applied to lever b. The free end of lever b may be enlarged and hollowed,

page_text: as shewn, so as to be operated by the knee. In the type of spindle represented in
Figure 1, the bolster bearing is formed of two sleeves or bushes & pivoted the one
in the other and in an aperture in the bolster rail m in the manner of gimbals, as
shewn at A, said bushes being made cylindrical on the interior and conical on the
exterior so as to have sufficient play to permit of the lateral shifting of the spindle,
as before described.

COMPLETE SPECIFICATION.
Improvements in Mounting and Driving Spindles of Continuous
Spinning Machines.
We JULES DÉSIRÉ RYO, ALPHONSE MARIE RYO and HECTOR RYO, all of
Roubaix (Nord) France, Machine Builders do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :--
Our invention relates to improvements in mounting and driving the spindles of
continuous spinning machines, whereby the speed at which the spindles can be
driven is rendered theoretically unlimited while they may also be instantly put
out of action.
The invention which is especially adapted for facilitating overlooking and piecing
up broken threads consists essentially in the herein described means whereby the
spindle is shifted horizontally along with its footstep bearing for the purpose of
throwing it in or out of gear.
Reference is to be had to the accompanying drawings forming part of this
Specification wherein
Figure 1 represents a side elevation partly in vertical section of the improvement
as applied to what is known as a "Union" spindle.
Figure 2 is a front elevation also partly in section and
Figure 3 a plan of the same.
Figure 4 is an elevation of the device for holding the spindle in and out of gear.
Figure 5 shows a modification of the same.
The same letters of reference denote like parts in all the figures.
C
a is the spindle mounted in its footstep bearing which is carried upon a
horizontally moving lever e pivoted at d, the spindle being driven by a friction
disc e by contact with the elastic or roughened friction ring f which revolves in
frictional contact with a metal collar g on the spindle. The collar g and disc e are
held in contact by an arrangement consisting of an elbow lever h pivoted on a
centre o upon a plate i fixed adjustably on the front of the rail k. The plate i is
notched on its upper edge to receive the end of the oscillating lever c against which
the upper arm of elbow lever presses, the notch limiting the movement of the
lever e in either direction.
The contact of the spindle with the friction disc is
maintained by the weight attached to the lever, this weight being capable of
being varied or of being replaced by a spring. n is a latch pivoted at m on the side
of the lever arm c and resting, while the spindle is running, upon the plate i as
shown, but which when the lever c is moved away from the friction disc e at once
drops into the notch in plate i, thus retaining the spindle a out of contact with the
friction disc, as shown in dotted lines in Figures 2 and 3, the running of the spindle
being thus stopped instantly by a very slight shifting motion. The latch n instead
of being parallel to the lever c and falling between it and the end of the notch
in the plate i, may be so pivoted to the latter as to move in a plane at right

page_text: angles to lever e and engage therewith, so as to hold it in the out of gear position,
one such form being shown in Figure 5.
Although we have shown our improvements as applied to a "Union" spindle
as the one which gives the best results, it will be understood that the invention
is entirely independent of the kind of spindle to which it may be applied.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is―
1. In a continuous spinning machine wherein the spindles are driven by friction
gear as described, mounting the spindle upon a horizontally movable lever whose
shifting motion is limited preferably by an adjustable notched plate, as described.
2. The combination with the horizontally moving lever support for the spindle
as described, of a latch engaging automatically with said lever when the latter is
moved against the pressure of a weighted or spring actuated elbow lever by which
the spindle is held in gear, as described.
