Year: 1868

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 OIL CUPS OR LUBRICATORS FOR
MACHINERY."-A communication from abroad by Henry L. Fearing,
President of the New England Patent Oil Cup Company, of Boston,
PROVISIONAL SPECIFICATION left by the said William Edward Newton
at the Office of the Commissioners of Patents, with his Petition, on
the 27th November 1868.
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 OIL CUPS OR LUBRICATORS
FOR MACHINERY," to be as follows:-
This Invention consists, first, in casting around and within the neck
of a glass reservoir a metallic collar for the purpose of connecting the

page_text: reservoir to the supporting stem; second, in combining with the collar
a threaded bushing or tube of harder metal for the reception of the
stem; third, in employing within the hollow stem of a lubricator a
regulating rod provided at its upper end with an enlargement or
projection for the purpose of supporting the rod out of contact with
the journal; and, fourth, in the use in the place of the regulating rod
of a hollow tube open at the bottom but closed at the top, and having
a hole drilled in its side near its upper end so as to communicate with
the reservoir, the tube being screwed into the hollow stem for the
purpose of facilitating the regulation of the flow of oil to the journal or
bearing.
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 27th May 1869.
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 Twenty-seventh day of November, in the
year of our Lord One thousand eight hundred and sixty-eight, in the
thirty-second year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said William Edward Newton, Her
special licence that I, the said William Edward Newton, my executors,
administrators, 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 OIL CUPS OR LUBRICATORS FOR MACHINERY," being a com-
munication to me from abroad, 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

page_text: 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 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 here-
unto annexed, and to the letters and figures marked thereon (that is
to say):
==
This Invention consists, first, in casting around and within the neck
of a glass reservoir a metallic collar for the purpose of connecting the
reservoir to the supporting stem; second, in combining with the collar
a threaded bushing or tube of harder metal for the reception of the
stem; third, in employing within the hollow stem of a lubricator a
regulating rod provided at its upper end with an enlargement or
projection for the purpose of supporting the rod out of contact with
the journal; and, fourth, in the use in place of the regulating rod of
a hollow tube open at the bottom but closed at the top and having
a hole drilled in its side near its upper end so as to communicate with
the reservoir, the tube being screwed into the hollow stem as shewn for
the purpose of facilitating the regulation of the flow of oil to the journal
or bearing.
In the accompanying Drawing, Fig. 1 is an elevation of an oil cup
embodying the above-mentioned improvements; Fig. 2 represents a.
vertical section thereof; Fig. 3 is a transverse section on the line 1, 2,
on Figures 1 and 2; Fig. 4 is a transverse section on the line 3, 4, in
Figures 1 and 2; and Fig. 5 is a vertical section shewing another modifi-
cation of the Invention.
In Figures 1, 2, and 5, A represents the journal to be lubricated; B
its bearing, and C the cap; E is a hollow stem screwed into the cap C
to conduct oil to the journal A; D is a rod to regulate the flow of oil
through the stem E. To allow the oil to flow through the stem the
rod D is made somewhat smaller than the aperture therein, or is formed
with a flat side, as shewn in Fig. 4. To support the rod out of contact
with the journal it is formed with a projection or enlargement d on its
upper end which rests upon the top of the hollow stem E. By means
of a number of rods of different sizes the rapidity of the flow of oil

page_text: may be varied as desired. In the arrangement represented in Fig. 5,
the flow of oil may be regulated to a nicety by screwing the hollow
tube T up or down in the stem so that more or less of the side opening e
will be above the top of the stem E, thereby, exposing a larger or smaller
opening for the oil according as the circumstances may require. At
the upper end of the stem E is a screw fitting an internally threaded
bushing F which is secured to the neck H of the glass globe G by a
collar I of fusible metal compounded substantially as follows:-Tin,
two pounds; lead, one pound; bismuth, about one ounce; antimony,
about two ounces. The purpose of the bismuth is to make the molten
metal flow more freely. The object of the antimony is to render it more
hard and firm when set. Having melted the tin, lead, and bismuth
together antimony is added until the molten mass acquires a bright
clear lustre. For this purpose it is believed that to take about the
proportionate quantity named above, grooves h in the glass H adapt
it to firmly retain the soft metal band I. For the same purpose any
suitable inequalities may be formed on the periphery of the tube or
bushing F. The band or collar I is cast around and within the neck H
and either with or without the threaded bushing F constitutes an air-
tight and strong attachment for the supporting stem E. A washer J
may be employed to form an air-tight joint between the stem E and
collar I when the former is screwed into the latter as shewn.
Having now described the Invention which has been communicated
to me as aforesaid, I would remark that what I consider as new and
desire to secure by Letters Patent is,-
First. Constructing oil cups with a metallic band or collar I cast
around and within the neck of the reservoir G for the purpose of
attaching the supporting stem E thereto as specified.
Second. In combination with the band or collar I of soft or fusible
metal applied as set forth, I claim the threaded tube or bushing F of
harder metal for the reception of a screw on the upper end of the
stem E.
Third. The use of the rod D formed with a projection or enlarge-
ment d on its upper end to support it out of contact with the journal as
described.
Fourth. The hollow tube T open at the bottom and closed at the top,
and provided with a side aperture and fitted to the hollow stem E so

page_text: that the flow of oil may be regulated simply by screwing the tube up or
down as described.
In witness whereof, I, the said William Edward Newton, have
hereunto set my hand and seal, the Twenty-seventh day of May,
in the year of our Lord One thousand eight hundred and sixty-
nine.
