page_text: We, BENJAMIN ALFRED DOBSON, of Kay Street Works, Bolton, in the
County of Lancaster, Engineer, and JAMES TURPIE, of 30 Simpson Street,
Bolton aforesaid, Spindle Foreman, do hereby declare the nature of this invention
to be as follows:-
Our invention is applicable to those spindles for spinning or doubling in which
the lower part of the spindle runs in an inside pillar or bearing. This pillar in
general is placed loosely inside an outer pillar bearing, and when for any reason it
is necessary to lift the spindle in most cases the inside pillar is lifted with it. To
replace the inside pillar requires careful adjustment as there is on it a pin taking
into a slot on the outer pillar, the pin being for the purpose of preventing the inside
pillar revolving by the friction of the spindle. This pulling out of the inside pillar
is very objectionable in practice.
Now we overcome this defect by cutting towards the upper part of the inside of
the outer pillar a circular groove, and a vertical groove crossing this and extending
some distance down the inside of the outer pillar, the grooves being approximately
of the same depth; on the outside of the inner pillar we cut a vertical groove or slot
part of the length of the bearing, and in this we fix a steel or other spring catch
which is fixed in this slot by brazing, soldering or other means. This catch has
part way up its length a semicircular or other bend which projects beyond the
depth of the slot and prevents the revolution of the inside pillar, instead of the pin
ordinarily employed for this purpose. At the upper end the catch makes a T head
and this part of the T is slightly inclined from the inner pillar the result being
that when the inner pillar is fitted into the outer pillar the semicircular projection
on the spring catch taking into the groove prepared for it in the outer pillar guides
the inner pillar to its place, and prevents its revolution whilst the T head portion
of the same catch springs into the horizontal groove thereby preventing the inner
pillar from being withdrawn without the application of a certain amount of force
which is more than that exercised by the friction of the spindle upon the inner
pillar when being lifted out. The spring catch has no other function except those
above mentioned.

and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-.
Our invention is applicable to those spindles for spinning or doubling in which
the lower part of the spindle runs in an inside pillar or bearing. This pillar in
general is placed loosely inside an outer pillar bearing and when for any reason it
is necessary to lift the spindle in most cases the inside pillar is lifted with it. To
replace the inside pillar requires careful adjustment as there is on it a pin taking
into a slot on the outer pillar, the pin being for the purpose of preventing the
inside pillar revolving by the friction of the spindle. This pulling out of the inside
pillar is very objectionable in practice.
Now we overcome this defect by cutting towards the upper part of the inside of
the outer pillar a circular groove and a vertical groove crossing this and extending
some distance down the inside of the outer pillar the grooves being approximately
of the same depth. On the outside of the inner pillar we cut a vertical groove or
slot part of the length of the bearing and in this we fix a steel or other spring catch
which is fixed in this slot by brazing soldering or other means.
And in order that our invention may be fully understood and readily carried
into effect we will describe the accompanying sheet of drawings reference being
had to the figures and letters marked thereon.
Figure 1 is a vertical section of a spindle bearing fitted with our improvements.
Fig. 2 is a sectional plan taken on the plane of the line X X, Fig. 1.
Fig. 3 is a view of the inner pillar detached and
Figs. 4 and 5 are views of the spring catch detached.
C
In the drawings, a designates the spindle, 6 the sleeve fitted thereon, 6¹ the
wharve, c the outer pillar or bolster bearing which is secured as usual by a nut & in
the spindle rail e, and the inside pillar or bearing in which the lower part of the
spindle a runs.
According to our improvements we cut a circular horizontal groove c¹ and a
vertical groove intersecting it in the inside of the outer pillar c; and we cut a
vertical groove f¹ on the exterior of the inside pillar f and we fit and secure
a spring catch g in the groove f. The spring catch may be secured in its groove
in any convenient manner for example we have shown it made with a T head at
each end the lower Thead fitting in a groove f2 intersecting the groove fl whereby
the catch is prevented from moving vertically and it is also prevented from
springing out by hammering over the edges of the groove f¹ for a certain distance
as indicated in Fig. 3. The catch g has part way up its length a bend g¹ of semi-
circular or other suitable form which projects beyond the depth of the groove f¹
and prevents the revolution of the inside pillar of instead of the pin ordinarily
employed for this purpose. The upper T headed end g² of the spring catch is
slightly inclined from the pillar f, the result being that when the inner pillar fis
fitted into the outer pillar c the bend g¹ taking into the groove c² prepared for it in
the outer pillar guides the inner pillar f to its place and prevents its revolution,
while the headed end 92 springs into the horizontal groove c' in the outer pillar c
thereby preventing the inner pillar from being withdrawn without the application
of a certain amount of force which is more than that exercised by the friction of
the spindle upon the inner pillar f when the spindle is being lifted out.
The spring catch g, which may be made of steel, has no other function except
those above mentioned.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. The use and application of a spring catch arranged substantially as herein
described so as to prevent the revolution of the inner pillar or spindle bearing and
also to prevent said bearing from being withdrown when the chindle is lifted aut

page_text: 2. In combination, the outer pillar c provided with grooves c³ ³, the inner pillar f
provided with a vertical groove or slot f¹ and the spring catch g formed with a
bend g¹ to engage the groove c³ and a T headed end g' to engage the groove c' all.
substantially as and for the purposes herein set forth.
