Improvements in or connected with the Spindles of Spinning or
Twisting Frames.
I, ERNEST DE PASS, of 78 Fleet Street, in the City of London, Fellow of the
Institute of Patent Agents, do hereby declare the nature of this Invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement, reference being had to the accompanying
drawings and to the letters and figures marked thereon, that is to say :-
:-
In the specification of the Letters Patent dated 13th July 1888, numbered 10,205,
I described (as communicated to me by the said Joseph Imbs) an arrangement of
spindles, more particularly of the self-acting kind, revolving between an exterior
support and friction rollers placed internally, and contained in a closed box in which
these rollers were supplied with continuous oiling. Now, according to the present
invention, I apply to this arrangement of spindles, certain useful and practical
improvements about to be described.
In the accompanying drawings Figs. 1 and 2 are sectional views (half size) shewing
the spindle with its improved parts. Fig. 1x, is a plan of the bolster-rail, and Fig. 2×
a view, in plan, of a detail relating to a brake arrangement hereinafter described.
The exterior support which the spindles require in order to avoid any backward
vibration, which they might receive from rapid working, is not satisfactory if it be
obtained from the same piece common to several spindles.
It is necessary that each spindle should have an independent piece which shall be
capable of adjusting a kind of cap-piece or bearing-block close up against the
spindle, without pressure, and likewise with scarcely any play. Therefore in the side
of the bolster-rail P, I place, opposite each spindle, a fine threaded screw v, and on
the inner side of said rail a bearing-block. This bearing-block is mounted on the
end of the screw and is adjustable forwards and backwards thereby. It is provided
with a groove which receives a wick issuing through a hole in the channel'p which
serves for oiling the bearing block as well as for supplying oil to the channel
for the friction rollers g. Thus the continuous oiling of the bearing block x, like
that of the friction rollers g, is ensured.
According to another improvement I form the lower rib pl of the bolster-rail P,
with a recess for the reception of the specially devised brakes for stopping the spindles
should it be required to piece the yarn. Fig. 2 shews, in plan, one of these brakes f.
The
It is formed as a kind of bolt which can be pushed to the left or to the right.
outer face of this bolt, along which the spindle passes, forins, as shewn in Fig. 2*, an
inclined plane or wedge. If, as is supposed in this figure the bolt is pushed to the
left, it will remove the spindle from the friction-rollers g, and firmly press or wedge
it against the bearing-block; the spindle will thus be stopped and remain out of
contact with the friction rollers until the bolt be again pushed to the right
According to another improvement, and in order to prevent the spindle B from
rising up, I utilize the metal plate t' which covers the bolster-rail P' of the steps. I
form the spindle cylindrical up to its foot, and above the pivot I place a screw ring or
collar O (fig. 1), or, by preference, I turn a neck on the spindle (fig. 2) and by
moving the metal plate ', forwards or backwards, the holes therein, through which
the spindles pass, can be brought into a position concentric with the spindles so that,
if necessary, the spindles can be removed. But when working, these holes are brought
into a position eccentric with the spindles, and bear against the bottom of the neck b,
the metal plate t¹ will then form an obstruction to any verticle movement of the
spindles.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I claim :-
1. The employment, with spindles revolved against friction rollers, of cap-pieces or
retaining bearing blocks place opposite the friction rollers, said bearing-blocks
being adjustable and independent for each spindle, substantially as described and
shewn.
2. The means for ensuring the continuous oiling of the adjustable bearing-blocks,
substantially as described and shewn.
3. The employment, with spindles revolved against friction rollers, of brake bolts
capable of wedging and stopping the rotation of the spindles by removing them out
contact with the friction rollers, substantially as described and shewn.
Dated this 16th day of June 1890.
