I BENJAMIN DYSON of Stones Mill, Rishworth near Ripponden in the county.
of York, Engineer, do hereby declare the nature of this Invention to be as
follows:-
My improvements are as follows:-in the lubricator cup proper, is a piston, the
rod or spindle of which is screwed upon its outside, and upon which works a worm
wheel and nut, the nut carries a projection; at the top of the screwed spindle which
is hollow, is a second small tallow receiving cup attached to the spindle, a stopper
screws into the spindle to cork it, on the cup is formed a hand wheel, below the cup
is a collar tapped on to the screwed spindle, this collar carries a catch which holds a
stud fast until the spindle and piston are nearing the bottom of the lubricator, when
the catch comes in contact with the projection on the nut, which knocks off the catch,
and allows the stud to drop, so that the nut on the worm wheel carries the spindle and
cup around with it, and so the piston does not continue its descent, and no damage
can be done, the worm wheel is operated by a worm working in a lubricating trough;
on the same shaft is the usual ratchet and ratchet wheel for operating it, each part of
the lubricator can be detached for repairs without trouble the sight feed can be
detached from the cup, and placed in any convenient position, and on a glass breaking
there are two passages, one of which can be closed, until the glass is repaired, the
lubricator being able to work at the same time.
Doted this Tenth day of November 1886.

page_text: I BENJAMIN DYSON of Stones Mill, Rishworth, near Ripponden in the County of
York, Engineer do hereby declare the nature of this Invention and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement :-
My improvements are as follows: in the lubricator cup proper is a piston, the rod or
spindle of which is screwed upon its outside, and upon which works a worm wheel and
nut, the nut carries a projection; at the top of the screwed spindle which is hollow, is
a second small tallow receiving cup attached to the spindle, a stopper screws into the
hollow of the spindle to cork it, on the cup is formed a hand wheel, below the cup is
a collar tapped on to the screwed spindle this collar carries a catch which holds a
stud fast until the spindle and piston are nearing the bottom of the lubricator, when
the catch comes in contact with the projection on the nut which knocks off the catch,
and allows the stud to drop, so that the nut on the worm wheel carries the spindle
and cap around with it, and so the piston does not continue its descent, and no
damage can be done; the worm wheel is operated by a worm working in a lubricating
trough; on the same shaft is the usual ratchet and ratchet wheel for operating it.
Each part of the lubricator can be detached for repairs without trouble, the
sight feed can be detached from the cup and placed in any convenient position,
and on a glass breaking there are two passages, one of which can be closed
until the glass is repaired, the lubricator being able to work at the same time.
Fig. 1 is a front elevation in section of my improved lubricator.
Fig. 2 is an elevation of my improved lubricator showing a modification of the
arrangement for automatically stopping the piston as it nears the bottom of the
lubricator. Fig. 3 shows lubricator stopped.
In the lubricator cup A proper is a piston B, the rod or spindle C of which is
screwed upon its outside, and upon which works a worm wheel D, and nut E, the nut
carries a projection F; at the top of the screwed spindle (which is hollow) is a second
small tallow receiving cup G, attached to the spindle, a stopper H screws into the
hollow of the spindle to cork it; on the cup is formed a hand wheel J, below the cup
is a collar K, tapped into the screwed spindle C, this collar carries a catch L, which
holds a stud M, fast, until the spindle and piston are nearing the bottom of the
lubricator, where the catch L comes in contact with the projection F, on the nut E,
which knocks off the catch L, and allows the stud M to drop, so that the nut on the
worm wheel carries the spindle and cup around with it, and so the piston does not
continue its descent, and no damage can be done. Or instead of this knocking off

page_text: arrangement, I place upon a rod V, a collar W, which is secured by a set screw or
other means, and can be placed in any position on the rod.
Under the ratchet I place a wedge X carried by a pivotted lever Y, the end Z of
the lever extending to the rod, and collar, as the piston rod descends and the collar
comes in contact with the lever end Z, it depresses it and raises the wedge X, and
pushes the ratchet out of gear with the ratchet wheel and so stops the working of the
piston and cylinder, (see Fig. 3) the collar V being adjustable it can be placed so as to
knock off at any required position.
The worm wheel is operated by a worm N, working in a lubricating trough P, on
the same shaft R is the usual ratchet wheel T, operated by ratchet S for operating it,
each part of the lubricator can be detached for repairs without trouble, the sight feed
can be detached from the cup, and placed in any convenient position, and on a glass
breaking, there are two passages one of which can be closed until the glass is repaired,
the lubricator being able to work at the same time.
Having now particularly described and ascertained the nature of this invention and
in what manner the same is to be performed I declare that what I claim is :-
1. The general arrangement, construction and combination of parts of sight feed
lubricators, as shown and described.
2. Supplying the lubricant to the underside of the piston, by means of the hollow
spindle, cup and stopper, for the purposes shown and described.
3. The combination of the boss K, catch L, pin M, and projection F, on the nut E,
for preventing the piston from descending too far, as shown and described.
4. Knocking off the ratchet automatically, so as to stop the descent of the piston at
any given point, as herein before shown and described.
