IMPROVEMENT IN SPINNING AND DOUBLING SPINDLES
Year: 1885

page_text: We BENJAMIN ALFRED DOBSON, of the firm of, Dobson and Barlow, Machine
Makers, of Kay Street Works, Bolton, Lancashire and EDWARD GILLOW and
RICHARD CRABTREE, of the same place, Foremen, do hereby declare the nature of
said Invention for AN IMPROVEMENT IN SPINNING AND DOUBLING SPINDLES to be
as follows:
Our invention relates to an improvement in spindles having elastic or movable
bearings and consists in an arrangement for preventing the cushioning substance
from working its way out of the bolster in which it is confined through the vibra-
tion of the spindle.
This arrangement consists in the application of a nut screwed into the interior
of the outside bolster in which of course it fits tightly and acts by compression
upon the cork, felt, or other substance which acts as a cushion to the spindle. We
may also have the inside, bolster arranged so that it is bored part way down a
certain diameter larger than the hole through which the spindle holder passes
leaving a ledge further up the bolster. We again bore a larger diameter leaving
another ledge and at the outside extremity we tap the bolster inside to the screw
as before described; on the spindle holder or tube is a projection which about fits
the diameter of the larger hole described. This projection may be slightly rounded
or barrelled and its lower portion must be turned to the radius of about half the
diameter of the larger hole to fit upon the second ledge already described. When
we put the spindle together we have a cork, india-rubber, felt, or other cushioning
substance which we insert in the space left between the first ledge as described.
We then put in the spindle holder and press it down until it comes on the top of
the cushioning substance and then put in the cushioning substance from the tapped
projection on the spindle holder already described and then placing the nut in the
screwed part, we screw it down until it has pressed the cushioning substance well
against the spindle holder and made all sufficiently solid to resist the vibration.
This nut is only in contact with the outside bolster and the cushioning substance,
and is not touched by either the spindle or the spindle holder. We may cut upon
the spindle two grooves each starting from the extreme bottom of the taper part of
the spindle and being continued with a slight screw up to the collar of the spindle.
This will, under certain conditions, providing the grooves do not cross each other,
allow of a spindle being run in either direction and still baving sufficient power to
raise the lubricating matter from the foot of the collar,

page_text: In some cases for the purpose of holding down the spindle while removing the
bobbin for doffing or piecing we may slightly increase the diameter of the bottom
flange under the wharve and by returning a small flange inward toward the centre
of the spindle we can place our holding down hook inside and it can be disengaged
by the pressure of the hand and is kept to its work either by a spring or by
gravity.
When we apply the above arrangement to that class of spindle which is known
in the trade as the "Dobson-Marsh self lubricating spindle we may by one or
more slots in the inner surface of the bolster allow the.lubricant raised by the
spindle to descend on the outside of the spindle holder and the inside of the flange
down to the oil reservoir thus avoiding the necessity for the intermediate cup at
present used in the Dobson-Marsh spindles.

An Improvement in Spinning and Doubling Spindles.
We BENJAMIN ALFRED DOBSON, of the firm of Dobson and Barlow, Machine
Makers, of Kay Street Works, Bolton, Lancashire, and EDWARD GILLOW and
RICHARD CRABTREE, of the same place, Foremen, do hereby declare the nature of
said Invention for AN IMPROVEMENT IN SPINNING AND DOUBLING SPINDLES, 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 an improvement in spindles having elastic or movable
bearings and consists in an arrangement for preventing the cushioning substance
from working its way out of the bolster in which it is confined through the
'vibration of the spindle.
This arrangement consists in the application of a nut screwed into the interior
of the outside bolster in which of course it fits tightly and acts by compression
upon the cork, felt, or other substance which acts as a cushion to the spindle. We
may also have the inside bolster arranged so that it is bored part way down a
certain diameter larger than the hole through which the spindle holder passes
leaving a ledge further up the bolster. We again bore a larger diameter leaving
another ledge and at the outside extremity we tap the bolster inside to the screw
as before described; on the spindle holder or tube is a projection which about fits
the diameter of the larger hole described. This projection may be slightly rounded
or barrelled and its lower portion must be turned to the radius of about half the
'diameter of the larger hole to fit upon the second ledge already described.

page_text: When we put the spindle together we have a cork, india-rubber, felt, or other
cushioning substance which we insert in the space left between the first ledge as
described. We then put in the spindle holder and press it down until it comes on
the top of the cushioning substance and then put in the cushioning substance from
the tapped projection on the spindle holder already described and then placing the
nut in the screwed part we screw it down until it has pressed the cushioning
substance well against the spindle holder and made all sufficiently solid to resist
the vibration. This nut is only in contact with the outside bolster and the
cushioning substance and is not touched by either the spindle or the spindle
holder. We may cut upon the spindle two grooves, each starting from the
extreme bottom of the taper part of the spindle and being continued with a slight
screw up to the collar of the spindle. This will, under certain conditions, providing
the grooves do not cross each other, allow of a spindle being run in either direction
and still having sufficient power to raise the lubricating matter from the foot of
the collar.
When we apply the above arrangement to that class of spindle which is known
in the trade as the "Dobson-Marsh self lubricating spindle," we may by one or
more slots in the inner surface of the bolster, allow the lubricant raised by the
spindle to descend on the outside of the spindle holder and the inside of the flange
down to the oil reservoir, thus avoiding the necessity for the intermediate cup at
present used in the Dobson-Marsh spindles.
And in order that our Invention may be fully understood and readily carried
into effect we will describe the accompanying two Sheets of Drawings, reference
being had to the figures and letters marked thereon.
Figure 1 is a sectional elevation of a spinning frame spindle on the Dobson-
Marsh principle to which our improvements are applied and Fig. 2 is a similar
view of a doubling frame spindle also on the Dobson-Marsh principle.
In these views.- -a designates the spindle, 6 the spindle rail, c the wharve, d the
outside bolster, e the oil reservoir, f the spindle holder or tube, g g¹ the cushioning
substance or substances, and h the nut.
The bolster d is bored out so as to leave a ledge on which the cushioning
substance grests and a second ledge d³ on which, and the cushioning substance g,
rests the lower side of the projection f¹ which may be rounded or barrelled and is
formed on the spindle holder or tube f; the upper side of this projection f¹ forms
a ledge on which rests the cushioning substance g'. The interior of the bolster
is threaded to receive the nut h which is screwed down firmly upon the cushioning
substance g¹ and so compresses the substances g¹ and g against the projection f¹
and other portions of the spindle holder ƒ until every thing has been rendered
sufficiently solid to resist vibration.
In both views the spindle holder f is shown provided with a slot or groove f*
which arrangement permits the return to the reservoir e of the lubricant carried up
by the action of the revolving spindle. There may be one as shown or more of
these slots or grooves f².
Fig. 3 is a sectional elevation of an ordinary spinning frame spindle with a self
contained instead of a detachable oil reservoir and Fig. 4 is a sectional plan on the
line A B, Fig. 3.
These views illustrate the application of our Invention to a spindle of the
ordinary construction lubricated from a reservoir formed in an extension of the
bolster d.
Fig. 5 is a view of a spindle illustrating that part of our Invention which
consists in cutting upon the spindle a two grooves a¹ and a² respectively, each
groove starting from the extreme bottom of the taper portion of the spindle and
being continued upward with a slight screw until the grooves nearly meet on the
other side of the spindle to that on which they started.
The grooves a¹ a² do not cross one another and being cut in opposite directions
will raise the lubricant from the oil reservoir whether the spindle is run in one
direction or the other.

page_text: Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is.
1. The herein described improvement in spinning and doubling frame spindles
consisting chiefly in the use and application of a nut screwing into the outside
bolster, substantially as and for the purposes herein set forth.
2. In a spinning or doubling frame spindle, the combination with a bolster
formed with ledges such as d and d, a cushioning substance or substances such
as g and g² and a spindle holder or tube provided with a projection such as f¹, of
the nut screwing into the said bolster, substantially as and for the purposes
herein described and as illustrated by the accompanying Drawings.
3. The combination with the nut h, of the groove or grooves f³, substantially as
herein set forth for the purposes specified.
4. The combination with a spinning or a doubling frame spindle of the two
grooves a¹ and a², substantially as herein described and as illustrated by Fig. 5 for
the purpose of effecting the lubrication of the said spindle whether run in one
direction or the other.
