IMPROVEMENTS IN LUBRICATORS
Year: 1877

page_text: LETTERS PATENT to William Hainsworth, of Settle, in the County of York,
Contractor, for the Invention of "IMPROVEMENTS IN LUBRICATORS."
Sealed the 24th May 1878. and dated the 14th December 1877.
PROVISIONAL SPECIFICATION left by the said William Hainsworth at the
Office of the Commissioners of Patents on the 14th December 1877.
WILLIAM HAINSWORTH, of Settle, in the County of York, Contractor. "IMPROVE-
MENTS IN LUBRICATORS
"
The object of my Invention is to prevent the waste of oil or other lubricants
which usually takes place when lubricators of ordinary construction are em-
ployed
Lubricators constructed according to my Invention are applicable to locomotive
engines, railway carriages, and other vehicles, also to the bearings of evolving
shafts or bodies, such as loose pulleys and machinery in general, and it is so
arranged that oil is only supplied when such machinery is in motion, and shut off
when such machinery is at a standstill or rest.
According to my improvements I employ a cup or reservoir, in which a spindle
or valve is provided to regulate the amount of lubrication supplied, all as hereafter
described. This valve is fitted or seated on the upper or inner end of a tube or
passage through which the lubricant is supplied. This valve or spindle has one
end extending into the tube or passage, and the other end projecting into the
reservoir or cup. That portion of the valve resting on the seat is by preference
flat.
In order to supply the oil or other lubricants to the bearings or parts requiring
lubrication, an oscillating motion is imparted to the valve or spindle by means of a
pendulum, which is suspended from the lid or other convenient part, and into which
the upper projecting end of the valve or spindle is passed. This pendulum is
caused to vibrate by the shake or motion of the machinery to which the lubricator

page_text: is applied; by this means the valve is canted intermittingly on its seat; when such
is the case an intermittent supply of oil is admitted to the passage, and conducted
to the parts requiring lubrication.
The valve when not in motion fits upon its seat so closely that no oil can
pass it.
The stroke of the pendulum is increased or reduced by a regulating screw,
thereby reducing or increasing the amount of lubricating material supplied.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said William Hainsworth the Great Seal Patent Office on the 8th Junc
1878.
WILLIAM HAINSWORTH, of Settle, in the County of York, Contractor "IMPROVE-
MENTS IN LUBRICATORS."
The object of my Invention is to prevent the waste of oil or other lubricants
which usually takes place when lubricators of ordinary construction are em-
ployed.
Lubricatois constructed according to my Invention are applicable to locomotive
engines, railway carriages, and other vehicles, also to the bearings of revolving
shafts or bodies, such as loose pulleys and machinery in general, and it is so arranged
that oil is only supplied when such machinery is in motion, and shut off when such
machinery is at a standstill or rost.
According to my improvements I employ a cup or reservoir, in which a spindle
or valve is provided to regulate the amount of lubrication supplied, all as hereafter
described. This valve is fitted or seated on the upper or inner end of a tube or
passage through which the lubricant is supplied. This valve or spindle has one end
extending into the tube or passage, and the other end projecting into the
reservoir or cup. That portion of the valve resting on the seat is by preference
flat.
In order to supply the oil or other lubricants to the bearings or parts requiring
lubrication, an oscillating motion is imparted to the valve or spindle by means of a
pendulum which is suspended from the lid or other convenient part, and into which
the upper projecting end of the valve or spindle is passed. This pendulum is caused
to vibrate by the stroke or motion of the machinery to which the lubricator is
applied. By this means the valve is canted intermittingly on its seat; when such
is the case an intermittent supply of oil is admitted to the passage, and conducted to
the parts requiring lubrication.
The valve when not in motion fits upon its seat so closely that no oil can
pass it.
The stroke of the pendulum is increased or reduced by a regulating screw, thereby
reducing or increasing the amount of lubricating material supplied.
In order that my Invention may be more completely understood, reference is
given to the accompanying Sheet of Drawings, and letters of reference marked
thereon.

Figure 2, an elevation; and Figure 3, a plan looking at the top.
According to my improvements I employ a cup or reservoir a, in which a spindle
b is provided to regulate the amount of lubrication supplied. The valve or spindle
b is seated on the upper or inner end of a tube c; such tube c may form the lower
part of the cup or reservoir, and forms the passage c¹ through which the lubricant
is supplied. This valve or spindle 6 has one end d extending into the tube or
passage c', and the other end projecting into the reservoir or cup a; that portion of
the valve at e, and resting on the seat, is by preference flat
In order to supply the oil or other lubricants to the bearings or parts requiring
lubrication, an oscillating motion is imparted to the valve or spindle b by means
of a pendulum f, which is suspended from the lid g or other convenient parts, and
into which the upper projecting end of the valve or spindle b is passed, as shewn
at h. The pendulum f is caused to vibrate by the stroke or motion of machinery
to which the lubricator is applied. By this means the valve b is canted inter-
mittingly on its seat at c; when such is the case an intermittent supply of oil is
admitted into the passage c', and conducted to the parts requiring lubrication.
The valve when not in motion fits upon its seat so closely that no oil can
pass it.
In order to increase or reduce the stroke of the pendulum, I attach the upper end
thereof to a regulating screw i within the lid g, and thereby increase or decrease
the amount of cant given to the valve or pin, and consequently the amount of
lubrication supplied.
Having now described the nature of my said Invention, and shewn by Drawings
how the same may be carried into effect, I would have it understood that I do
not limit myself to the precise limits, details, or configurations of the various parts
I have explained and shewn, but what I do claim and desire to be secured to me by
Letters Patent is,―
Firstly. The means employed for canting the pin or valve b, substantially as and
for purposes herein set forth.
Secondly The arrangement and combination of parts forming the lubricator,
substantially as herein set forth
In witness whereof, I, the said William Hainsworth, have hereunto set my
hand and seal, this Sixth day of June, in the year of our Lord One
thousand eight hundred and seventy-eight
