Year: 1874

page_text: LETTERS PATENT to William Edward Newton, of the Office for Patents,
66, Chancery Lane, in the County of Middlesex, Civil Engineer,
for the Invention of "IMPROVEMENTS IN BOLSTERS AND STEP-BEARINGS FOR
THE SPINDLES OF SPINNING FRAMES; APPLICABLE ALSO TO OTHER SPINDLES
AND SHAFTS."-A communication from abroad by Charles Franklin
Wilson and Jesse Edward Folk, both of Brooklyn, in the State of
New York, United States of America.
Sealed the 3rd July 1874, and dated the 4th February 1874.
PROVISIONAL SPECIFICATION left by the said William Edward
Newton at the Office of the Commissioners of Patents, with his
Petition, on the 4th February 1874.
I, WILLIAM EDWARD NEWTON, of the Office for Patents, 66, Chancery
Lane, in the County of Middlesex, Civil Engineer, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN BOLSTERS AND STEP-

page_text: BEARINGS FOR THE SPINDLES OF SPINNING FRAMES; APPLICABLE ALSO TO OTHER
SPINDLES AND Shafts,” to be as follows:-
This Invention consists in a spirally slotted bearing or journal box in
combination with the spindle thereof, and an outer sleeve-like oil cup
attached to the spindle, whereby a most perfect lubrication of the
spindle is effected both when at rest and while in motion, and the oil is
prevented from being scattered or wasted.
The Invention also consists in a bolster applicable to the spindles of
spinning frames constructed wholly or mainly of sheet metal and com-
posed of an outer shell, which is secured to the rail by a nut below, and
a shouldered cap above, a perforated bearing for the spindle with oil box
at top, and a sleeve-like cup attached to the spindle and arranged
between the shell and the bearing, the whole forming a cheap, simple,
light, and close construction of bolster, readily put together by simply
bending over the edges or certain of them of the contiguous sheet metal
parts.
The Invention likewise consists in a novel construction of the step-
bearing for spindles, in which the step for the foot of the spindle is
composed of a cup closed at the lower end, with a block fitted into it
recessed to receive the foot of the spindle, the block having formed in it
one or more vertical holes whose lower ends are upon a level with or
below the bottom of the recess in which the spindle foot works, and are
connected with the lower end of the recess by one or more horizontal
holes through the lower part of the block, whereby a perfect circulation
of the oil about the foot of the spindle is kept up. The perforated block
is constructed of a brass or hard metal lower perforated foot bearing or
socket, around which is cast a soft metal casing having the one or more
vertical holes and horizontal hole or holes (necessary to circulate the oil)
formed in it by means of cores, which are afterwards withdrawn. This
construction is much cheaper and simpler than making the block wholly
of hard metal and drilling the requisite holes in it.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Edward Newton in the Great Seal Patent
Office on the 1st August 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
EDWARD NEWTON, of the Office for Patents, 66, Chancery Lane, in the
County of Middlesex, Civil Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourth day of February, in the year
of our Lord One thousand eight hundred and seventy-four, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Edward Newton, Her special
licence that I, the said William Edward Newton, my executors, admini-
strators, and assigns, or such others as I, the said William Edward Newton,
my executors, administrators, and assigns, should at any time agree
with, and no others, from time to time and at all times thereafter 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 "IMPROVEMENTS IN
BOLSTERS AND STEP-BEARINGS FOR THE SPINDLES OF SPINNING FRAMES; APPLICABLE
ALSO TO OTHER SPINDLES AND SHAFTS," being a communication to me from
abroad by Charles Franklin Wilson and Jesse Edward Folk, both of
Brooklyn, in the State of New York, United States of America, upon
the condition (amongst others) that I, the said William Edward Newton,
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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said William Edward Newton, do
hereby declare the nature of the said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained
in and by the following statement, reference being had to the Drawing
hereunto annexed and to the letters and figures marked thereon (that is
to say)-

page_text: attached to the spindle, whereby a most perfect lubrication of the spindle
is effected both when at rest and while in motion, and the oil is pre-
vented from being scattered or wasted.
The Invention also consists in a bolster applicable to the spindles of
spinning frames constructed wholly or mainly of sheet metal and com-
posed of an outer shell, which is secured to the rail by a nut below and
a shouldered cap above, a perforated bearing for the spindle with oil box
at top, and a sleeve-like cup attached to the spindle and arranged
between the shell and the bearing, the whole forming a cheap, simple,
light, and close construction of bolster, readily put together by simply
bending over the edges or certain of them of the contiguous sheet metal
parts.
The Invention likewise consists in a novel construction of the step-
bearing for spindles, in which the step for the foot of the spindle is
composed of a cup closed at the lower end, with a block fitted into it
recessed to receive the foot of the spindle, the block having formed in
it one or more vertical holes, whose lower ends are upon a level with or
below the bottom of the recess in which the spindle foot works, and are
connected with the lower end of the recess by one or more horizontal
holes through the lower part of the block, whereby a perfect circulation
of the oil about the foot of the spindle is kept up. The perforated block
is constructed of a brass or hard metal lower perforated foot-bearing or
socket, around which is cast a soft metal casing having the one or more
vertical holes and horizontal hole or holes (necessary to circulate the oil)
formed in it by means of cores, which are afterwards withdrawn. This
construction is much cheaper and simpler than making the block wholly
of hard metal and drilling the requisite holes in it.
In the accompanying Drawing Fig. 1 represents an elevation of the
spindle of a spinning frame with the improved bolster applied thereto,
also shewing in section the step bearing.
Fig. 2 is a plan of the block used in the step bearing.
Fig. 3, a vertical section of the bolster cap prior to putting the parts
of the bolster together.
Fig. 4 is an inverted plan of the cap.
Figures 5, 6, and 7 are exterior longitudinal views of the shell, the
journal box or bearing, and the sleeve cup of the bolster; and Figures 8,

page_text: Fig. 11 is a vertical section upon an enlarged scale of the whole
bolster with spindle as applied to the rail of a spinning frame.
A is the rail of the spinning frame and B the spindle; C is the shell
which surrounds the sleeve-like cup D and bearing or journal box E of
the spindle; G is an independent cap contracted at its top so as to
nearly fit the spindle without causing friction, and in conjunction with
an enlarged chamber b at top of the bearing E, serving to form an oil
reservoir, to which access for introduction of the oil is had through an
orifice c formed by a partly punched lip.
The shell C, the cap G, and the sleeve cup D, as also if desired the
bearing E, are made of sheet metal, although the bearing or journal
box E may be of cast metal.
The bolster is firmly secured to the rail A below by a nut H arranged
to screw on to the shell C beneath. The upper portion of the shell is
constructed with an enlarged upper portion to receive within it the
enlarged upper oil chamber portion 6 of the bearing and the upper edges
of the shell turned over the upper edges of the latter. The cap G is
also made with a shoulder d, Fig. 11, and enlarged lower portion to fit
or bear down on the upper turned over edges of the shell, and to slip
over and enclose the enlarged upper portion of the shell, and so that the
lower edges of the cap may be turned under such portion of the shell as
shewn at e, Fig. 11. The sleeve-like cup D, which is attached to the
spindle and revolves in the annular space between the shell and the
bearing, is also made of sheet metal, and is bent invariably above and
below to form a close chamber around the bearing, but extending some-
what below the latter.
The construction of the bolster, wholly or mainly of sheet metal as
described, is not only cheap, simple, and admits of the parts being
readily put together, but makes a tight bolster, from which the oil
cannot possibly be scattered by the centrifugal motion of the rapidly
running spindle.
To secure a perfect lubrication of the spindle thorough communication
is made though the bearing E with the surrounding cup D by perfora-
tions formed of spiral slots f. The oil introduced into the chamber 6 at
top of the bearing E runs down the spindle to the bottom of the bearing,
from whence it passes into the cup D, and the centrifugal force of the

page_text: having the holes h and i cored in it for use in connection with the oil
cup I, as herein set forth.
In witness whereof, I, the said William Edward Newton, have here-
unto set my hand and scal, the Twenty-ninth day of July, in
the year of our Lord One thousand eight hundred and seventy-
four.
