PROVISIONAL SPECIFICATION left by the said Robert Thatcher at the
Office of the Commissioners of Patents, with his Petition,
April 1864.
on the 8th
I, ROBERT THATCHER, of Brook Mills, Oldham, in the County of Lancaster,
Cotton Spinner, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN LUBRICATING MACHINERY FOR PREPARING, SPINNING, AND
DOUBLING COTTON AND OTHER FIBROUS SUBSTANCES," to be as follows:-
The first part of my Invention relates to the lubricating of slubbing, inter-
mediate, and roving bobbin wheels and spindles. I propose to form a groove
on the outside of the bolsters that support the spindles, and on that part of
the bolster on to which the bobbin wheel fits; in this groove I place a piece
of sponge or other suitable material which will absorb the oil, and give it as
required to the bobbin wheel and through a hole or holes, which I form in
the bolster to the spindle, by this means it will lubricate both the bobbin
wheel and the spindle.
The second part of my Invention relates to the lubricating of throstle and
doubler spindles, which may be carried out in various ways. I propose in the

page_text: first place to form holes in the bolster rails, which I pack with sponge or
other suitable material which will absorb the oil and give it to the spindle
as required, through a hole, which connects the one in which the sponge is
packed with the spindle. I propose, in the second place, to form a groove on
the outside of the bolster, and in this groove to place a piece of sponge or
other suitable material which will absorb the oil and give it to the spindle
as required, through a hole or holes which I form in the bolster; or, instead
of a groove being formed on the outside of the bolster, the bolster may be
made smaller in diameter than the hole in the rail into which it fits, and a
piece of sponge or other suitable material wrapped round the bolster, which will
absorb the oil and give it to the spindle through a hole or holes formed in
the bolster. The bolster may be fastened in the rail by a nut on the under side,
or the rail may be made with the holes smaller at the bottom than at the top,
when the bolsters may be screwed into the smaller part, or fastened with a set
I propose, thirdly, to form the bolster in two parts. The outer one fits
into the bolster rail, and the inner one, which supports the spindle, screws or
fits into the outer one. On the outside of the inner one I form a groove, and
in this groove I place a piece of sponge or other suitable material which
absorbs the oil and gives it to the spindle, as required, through a hole or holes
formed in the bolster. I propose, fourthly, when cup bolsters are used, to
place the sponge or other suitable material inside the cup and under the
washer, but outside the tube that supports the spindle. This sponge or other
suitable material will absorb the oil and give it to the spindle as required,
through a hole or holes formed in the tube.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Robert Thatcher in the Great Seal Patent Office on the
7th October 1864.

any time agree with, and no others, from time to time and all times there-
after during the term therein expressed should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "IMPROVE-
MENTS IN LUBRICATING MACHINERY FOR PREPARING, SPINNING, AND DOUBLING COTTON
AND OTHER FIBROUS SUBSTANCES," upon the condition (amongst others) that I,
the said Robert Thatcher, my executors or administrators; by an instrument
in writing under my, or their, or one of their hands and seals, should
particularly describe and ascertain the nature of the, said Invention, and in
what manner the same was to be performed, and cause the same to be;
filed in the Great Seal Patent Office within six calendar months next and;
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Robert Thatcher, do hereby declare
the nature of my said Invention, and in what manner the same is to be.
performed, to be particularly described and ascertained in and by the fol-
lowing statements:-
My Invention consists, first, in lubricating slubbing, intermediate, and
roving bobbin wheels and spindles, by means of a sponge or other absorbent
material, which is placed in a groove formed on the outside of the bolster
that supports the spindle, and on that part of it on to which the bobbin
wheel fits. This sponge or other absorbent material will absorb the oil and
give it to the bobbin wheel and spindle, as required.
I
Secondly, in lubricating throstle and doubler spindles by means of a piece
of sponge or other absorbent material applied as herein after described.
form holes in the bolster rails, which I pack with sponge or other absorbent
material which will absorb the oil, and give it to the spindle as required
through a hole which connects the one in which the absorbent material is
packed with the spindle. Or, instead of as above, I form a groove on the
outside of the bolster, and in this groove I place the spongo or absorbent
material which absorbs the oil, and gives it as required, through a hole in the
bolster to the spindle. Or, instead of as above, I make the bolster smaller in
diameter than the hole in the rail into which it fits, and I wrapt the absorbent
material round the bolster, when it absorbs the oil, and gives it to the spindle
through a hole in the bolster. In this case I fasten the bolster in the rail by
a nut in the under side, or I make the rail with holes smaller at the bottom.
than at the top, when I screw the bolster into the smaller part or fasten it
with a set screw. Or instead of as above, I make the bolster in two parts.
The outer one fits into the rail, and in the inner one, which supports the spindle,.
:

page_text: screws or fits into the outer one; on the outside of the inner one I form a
groove, and in this groove I place the absorbent material, which absorbs the
oil, and gives it, to the spindle as required through a hole in the bolster. Or,
instead of as above, when cup bolsters are used, I place the absorbent material
inside the cup and under the washer, but outside the tube that supports the
spindle. This absorbent material will absorb the oil, and give it to the spindle
as required through a hole in the bolster.
But in order that my Invention may be fully understood and readily
carried into effect, I will now proceed to describe the accompanying Drawing.
The first part of my Invention is shown in Fig. 1, which is partly in
section; a is the spindle; b, the bolster; c, the rail that carries the bolster;"
and d, the bobbin wheel. A groove is turned on the upper part of the bolster,
and filled with the sponge or other absorbent material e, and a cap f is
fastened over it, to keep the absorbent material in its place, the bobbin wheel
revolves on the outside of this cap; the oil is poured in at the top, between
the bolster and cap, when it is absorbed by the sponge or other absorbent
material, which gives it through a hole e¹ to the bobbin wheel, or a hole e
to the spindle, as required.
The second part of my Invention is shown by Figs. 2 to 7; Fig. 2 represents.
a section of a throstle or doubler spindle rail and bolster with my improve-
ments applied.
a is the spindle rail; b, the bolster that supports the spindle; c, the spindle;
d, a hole, which is formed in the rail, and packed with sponge or other absorbent
material, which absorbs the oil and gives it as required to the spindle through
a hole d'. Fig. 3 represents a section of a throstle or doubler spindle rail and
bolster, with my improvements applied. a is the spindle rail; b, the bolster that
supports the spindle, and c the spindle. A groove is formed on the outside of
the bolster, which is filled with the sponge d. The oil is poured down the hole
a', when it is absorbed by the sponge, and given through the hole d¹ to the
spindle as required. Fig. 4 represents a section of a throstle or doubler spindle
rail and bolster, with my improvements applied. a is the spindle rail; b, the
bolster, which is made smaller at the lower part, so that the sponge c can be
wrapped round it. This bolster is fastened in the rail by the nut d. The oil is
poured down the hole a¹, when it is absorbed by the sponge, and given through
the hole 6' to the spindle e as required. Fig. 5 represents a section of a throstle
or doubler spindle rail and bolster with my improvements applied. a is the
spindle rail; b, the bolster, which at the lower end screws into the spindle
rail, which is drilled wider above so as to admit of a piece of sponge c being
wrapped' round the bolster. The oil is poured down the hole 6', when it is.

page_text: absorbed by the sponge, and given through a hole 6 to the spindle d as
required. Fig. 6 represents a section of a throstle or doubler spindle rail
and bolster, with my improvements applied. a is the spindle rail; b, the
bolster, which is made in two parts, the outer one of which is fastened in the
rail, and the inner one is screwed into the outer one. There is a cavity c which
is filled with sponge formed between the two parts. The oil is poured down
the hole b', when it is absorbed by the sponge, and given through a hole b²
to the spindle d as required. Fig. 7 represents a section of a throstle or
doubler spindle rail and bolster with my improvements applied. a is the
spindle rail; b, the bolster, which is called a cup bolster, and is screwed into
the rail a; c is a washer, which helps to support the bobbin, and d is the
sponge (to absorb the oil), which is placed under the washer. The oil is
poured down the hole e', when when it is absorbed by the sponge d, which
gives it through a hole b¹ to the spindle f as required.
Having thus described the nature of my Invention, and the manner of
performing the same, I wish it to be understood that I do not confine myself
to the precise details herein set forth, as many variations may be made
therein, without in any way departing from the principle of my Invention,
but I claim as my Invention,-
Firstly, lubricating slubbing, intermediate, and roving bobbin wheels and
spindles by means of a sponge, or other absorbent material, applied as shown
and described in reference to Fig. 1.
Secondly, lubricating throstle and doubler spindles, by means of a sponge
or other absorbent material, applied as shown and described in reference to
Figs. 2, 3, 4, 5, 6, and 7.
In witness whereof, I, the said Robert Thatcher, have hereunto set my
hand and seal, this Sixth day of October, One thousand eight hundred
and sixty-four.
ROBERT THATCHER. (L.S.)
