AN IMPROVED LUBRICATOR
Year: 1846

page_text: CARTER'S SPECIFICATION.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
CARTER, of Oldham, in the County of Lancaster, Painter, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Scal of Great Britain, bearing date at West-
minster, the Fourteenth December, in the tenth year of Her reign, and in the
year of our Lord One thousand eight hundred and forty-six, did, for Herself,
Her heirs and successors, give and grant unto me, the said James Carter, Her
especial licence, full power, sole privilege and authority, that I, the said
James Carter, my executors, administrators, and assigns, and such others as
I, the said James Carter, my executors, administrators, or assigns, should at
any time agree with, and no others, from time to time and at all times
during the term of years therein expressed, should and lawfully might make,
use, exercise, and vend, within England and Wales, and the Town of Berwick-
upon-Tweed, my Invention of "AN IMPROVED LUBRICATOR;" in which said
Letters Patent is contained a proviso that I, the said James Carter, shall
cause a particular description of the nature of my said Invention, and in what
manner the same is to be performed, to be enrolled in Her Majesty's High
Court of Chancery within six calendar months next and immediately after the
date of the said in part recited Letters Patent, as in and by the same, reference
being thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
James Carter, do hereby declare that the nature of the said Invention, and
the manner in which the same is to be performed, is particularly described and

page_text: ascertained in and by the Drawings hereto annexed, and the following explana-
tion thereof, that is to say:-
My "improved lubricator" is applicable to lubricating shafts, bearing axles,
or other working surfaces of machinery in general, and consists of a simple
but efficient contrivance designed for the purpose of furnishing a certain quan-
tity of oil or other liquid lubricating matter to such shaft, axle, or other
working surface at certain determinable intervals, which intervals, as well as
the quantity of oil or other liquid lubricating matters supplied, may be easily
varied and altered at pleasure."
The construction and application of my Invention will be more readily ex-
plained and better understood by reference to the Drawing accompanying these
presents, in which my improved lubricator is shown, as applied to a bearing or
journal carrying a shaft about two and a quarter inches in diameter, and is
calculated to furnish the oil or other liquid lubricating matter once in every
five thousand two hundred revolutions of the said shaft. The Drawing is
made about the real size, and has figures and letters of reference marked
thereon, corresponding with the following description thereof:-Figure 1 is
a side elevation of the apparatus, and Figure 2 an end view; Figure 8
is a longitudinal section, and Figure 4 a transverse section of the same.
a, a, is the shaft or axle to be lubricated; b, b, is part of the journal or bearing
carrying the same; and c, c, is the cap or top plate of the said bearing. To
the top of the cap c, c, a box d is attached, to which is fixed a bracket é, e,
which carries the shafts f and g. Upon the shaft a, a, is keyed a worm h,
which is cast in two pieces (for the convenience of fixing on the shaft), and
fastened together with small screws. This worm actuates a worm wheel i,
having twenty teeth, and being fixed at one end of the shaft f, at the other
end of which is a worm j, taking into a worm wheel
teeth, and being fixed upon the shaft g, the other end of
l, driving a worm wheel m, having twenty-seven teeth.
at the upper end of a hollow plug n, which is ground true, and revolves in the
box d. To the top of this hollow plug n is fixed the cup or vessel O, which
contains the oil or other liquid lubricating matter. The plug n is open at top
and bottom, and has two openings p and q, one at each side; it is also provided
with a midfeather, extending above the opening p and below the opening q.
As the plug n revolves the opening 9, coming opposite to the screw r, allows
the oil to fill the space between the plug and the end of the screw r. The re-
volution of the plug then brings the opening p opposite the screw r, and allows
the oil left in the space between the screw and plug to pass through the lower
part of the plug on to the shaft a; at the same time the opening g comes
having also twenty
which carries a worm
This wheel m is fixed

page_text: opposite to the screw s, and fills the space between the end of the same and
the plug n, and so on alternately. Thus it will be seen that the quantity of
oil left in the spaces at the ends of the screws r and s is furnished to the
shaft a twice in each revolution of the plug n, and as the wheel m has twenty-
seven teeth, and the wheels i and have have each twenty teeth, then twenty
by twenty by twenty-seven gives ten thousand four hundred, therefore the oil is
furnished twice in ten thousand four hundred revolutions of the shaft a, or, as
above stated, once in five thousand two hundred revolutions. Of course it will be
evident that the quantity of oil may be regulated by means of the screws r and
s, and the intervals between each supply may also be regulated by altering the
relative proportions of the gearing. It will also be evident that the same
arrangements of mechanism may be applied with a slight variation to lubricating
flat surfaces, such as substituting a ratchet wheel and click, or other suitable
contrivance for the worm h.
Having now described the nature and object of my improvements, I wish it.
to be understood that I claim as my Invention the construction and arrange-
ment of mechanism, consisting of the box d and plug n, as shewn in the
Drawing, and above described, as applied to that purpose, without confining
myself to the particular mode of actuating the same, or to the exact propor-
tions or dimensions of different parts of the same.
In witness whereof, I, the said James Carter, have hereunto set my hand
and seal, the Twelfth day of June, One thousand eight hundred and
fanty coven
Inrolled the Fourteenth day of June, in the year above written.
