page_text: LETTERS PATENT to James Collingham, Worsted Spinner, and Thomas
Ellison Smith, Machine Maker, of the Town of Keighley, in the
County.of York, for the Invention of "IMPROVEMENTS IN THE STEPS
OF SPINDLES FOR SPINNING, ROVING, SLUBBING, DOUBLING, AND TWISTING
FRAMER."
Sealed the 29th May 1868, and dated the 3rd December 1867.
COMPLETE SPECIFICATION filed by the said James Collingham and
Thomas Ellison Smith at the Office of the Commissioners of Patents,
with their Petition and Declaration, on the 3rd December 1867,
pursuant to the 9th Section of the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JAMES
COLLINGHAM, Worsted Spinner, and THOMAS ELLISON SMITH, Machine Maker,
of the Town of Keighley, in the County of York, send greeting.
WHEREAS we are in possession of an Invention for "IMPROVEMENTS IN
THE STEPS OF SPINDLES FOR SPINNING, ROVING, SLUBBING, DOUBLING, AND TWISTING
FRAMES," and have petitioned Her Majesty to grant unto us, our executors,
administrators, and assigns; Her Royal Letters Patent for the same, and
have made solemn Declaration that we really believe ourselves to be the first
and true Inventors thereof.

page_text: NOW KNOW YE, that we, the said James Collingham and Thomas
Ellison Smith, do hereby declare that the following Complete Specification,
ander our hands and seals, fully describes and ascertains the nature of the
said Invention, and in what manner the same is to be performed, in and by
the following statement (that is to say) :-
Our Invention relates to certain improvements in the construction and
peculiar conformation of steps of spindles for spinning, roving, slubbing,
doubling, and twisting frames used in the treatment and manufacture of all
fibrous materials. The principal element in this Invention being a better
method of lubricating such steps by a lubricating chamber of the form. herein
described in combination with fibrous washers saturated with oil.
The annexed Drawing, with the several Figures thereon, will explain the
conformation and arrangements of these improvements.
Figure 1 represents a sectional elevation of one of our improved steps, and
Figure 2 a plan of the same, in which a is the spindle; b, the body of the
spindle step; c, the lubricating chamber in which is placed some fibrous or
spongy material in the form of washers to hold the oil; d, a small hole drilled
at an angle from the chamber c to the bottom of the step leading the oil to
the foot of the spindle a, the fibrous or spongy washers being always ready to
give out a sufficient amount of oil, at the same time preventing grit or dirt
from coming into contact with the step.
Another form of our improved step is shewn also in Figures 3 and 4;
Figure 3 is a sectional elevation, and Figure, 4 a plan of the same.
:
A, the spindle; B, the body of the spindle step; C, the lubricating
chamber, into which is placed the spongy or lubricating material which is
always saturated with oil, so that it comes into contact with the side of the
spindle through the gap D between the lubricating chamber C and the
recess where the spindle foot runs and is supported. We prefer to use in
these lubricating chambers washers of cotton woven separately or cut out of
the piece of the size necessary, but we also claim the use of any suitable.
material in the form of washers. for the purpose set forth.
Having now.described the nature and object of our said Invention for improve-
ments in the steps of spindles, for spinning, roving, slubbing, doubling, and,
twisting frames for all: fibrous materials, together with the manner in which the
same is to be performed or, carried, into effect, we would remark that we do not
confine ourselves: to the precise, conformation of these, steps herein, shewn, and
described, as long as the main features, of the said Invention are adhered to;
but what we claim as of our Invention; is, the construction and conformation
of the foot steps for spindles, and the materials and washers used, in the
