PROVISIONAL SPECIFICATION.
Improvements in Lubricating the Spindles Employed in Textile
Machinery.
I, THOMAS HENRY RUSHTON, Machinist, of Kay Street Works, Bolton, in
the County of Lancaster, do hereby declare the nature of this invention to be as
follows:-
My invention relates to the lubrication of those spindles to which loose oil
cups or reservoirs are attached, and generally known as the Dobson-Marsh
lubrication.
In these spindles there is a removable oil cup which can be taken off the spindle
while the latter is in motion for the purpose of filling the oil cup with lubricant,
and also for removing the sediment which settles in the cup.
The object of my present invention is to avoid the necessity of removing the oil
cup except at the rare intervals necessary to clean out the sediment, and this I
effect by casting or fixing a snug or projection on the exterior of each loose oil cup,
and I make a communication between this snug from the outside to the inside of
the cup in such a manner that I can apply the spout of the oil can to the hole in
the snug and fill the cup with oil to the level of the hole which is then right for
lubricating the spindle.
"
In order to prevent dirt or "fly entering the oil cup I hinge a cover to the top
of the snug, so formed that it will automatically fall and cover the opening in the
snug by its own weight, and I prefer to make the cover project a little or shape it
so that it can be lifted by the spout of the oil can, and when the lubrication is
completed and the spout removed will fall to its place and cover the opening.
Dated this 22nd day of May 1895.

Improvements in Lubricating the Spindles Employed in Textile
Machinery.
1, THOMAS HENRY RUSHTON, Machinist, of Kay Street Works, Bolton, in
the County of Lancaster, 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 :-
My invention relates to the lubrication of those spindles to which loose oil
cups or reservoirs are attached and generally known as the Dobson-Marsh
lubrication.
In these spindles there is a removable oil cup which cau be taken off the spindle
while the latter is in motion for the purpose of filling the oil cup with lubricant,
and also for removing the sediment which settles in the cup.
The object of my present invention is to avoid the necessity of removing the oil
cup except at the rare intervals necessary to clean out the sediment, and this I
effect by casting or fixing a snug or projection on the exterior of each loose oil

page_text: cup, and I make a communication between this snug from the outside to the inside
of the cup in such a manner that I can apply the spout of the oil can to the hole in
the snug and fill the cup with oil to the level of the hole which is then right for
lubricating the spindle.
And in order that my invention may be fully understood and readily carried
into effect I will describe the accompanying sheet of drawings reference being had
to the figures and letters marked thereon.
Figure 1 is an elevation, partly in section, of a spindle fitted with my improved
oil cup.
Figs. 2 and 3 are side elevation and plan respectively of the oil cup detached,
and
Fig. 4 is a plan of the oil cup without its cover.
In Figure 1,-a is the spindle, the bolster rail, and c the nut to which is
attached my improved oil cup d by any suitable form of connection, as for
example, by a split ring e and grooves as shown. The oil cup d has according to
my invention a snug or projecting portion d' cast with it in which is formed a
passage d by means of which the cup can be filled with oil without detaching it
from the nut c.
In order to prevent dirt or "fly" entering the oil cup I hinge a cover fat f¹ to
the top of the snug d', this cover being so formed that it will automatically fall
and cover the opening d³ in the snug by its own weight, and I prefer to make the
cover project a little as shown in Figs. 1 and 2 or shape it so that it can be lifted
by the spout of the oil can, and when the lubrication is completed and the spout
removed will fall to its place and cover the opening.
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 :-
The combination with a self lubricating spindle a, of the improved removable
oil cup d formed with a projection d' having a passage d² closed by a cover fall
substantially as and for the purposes herein described and as illustrated by the
accompanying drawings.
