PROVISIONAL SPECIFICATION.
Improvements in "Visible Drop Feed
Lubricators.
I, WILLIAM HOLLIDAY, of St Kilda Terrace, Brixham, Devon, Engineer,
do hereby declare the nature of said invention to bo as follows:-
My invention is designed to obtain a perfectly reliable lubricator with "visible
drop feed," adjustable with the greatest exactness to any 10quired extent, from the
outside, and with provision for instantly cutting off the supply when the engines
are standing and to renew it when started, in such a way as to shew distinctly when
the feed is cut off and when operating, without any excuse for negligence.
"
"
The lubricator will preferably consist of an oil reservoir fixed in some cou-
veniently conspicuous position from which pipes will lead from each feed nozzle to
the various parts requiring lubrication. The lubricators which project through
the bottom and into the inside of the reservon, each consist of a tube terminating
in a tapered or inverted coned end, with small perforated holes for the issue of the
the upper part of
oil into the interior of a similarly inverted coned "nozzle
which is "tapped to work when evolved by a "milled" collar upon a fine
thead cut upon the parallel part of the tube, so that the issue of the oil through
the perforated holes can be adjusted in drops exactly to the requirements of the
is fixed by a winged
engine o machine, and when so adjusted the "nozzle
jam out milled collar with dilled holes corresponding with holes drilled in
the screwed tube to receive fixing pins, or other fixing device which will prevent
the supply varying by any vibiation. In the aperture of the perforated inner
coned tube a small screw is inserted which can at any time be removed to clean
through the tube. Tho "nozzle" being screwed home tho supply is entirely cut
off, but I prefer to prevent the possibility of waste from negligence by an arrange-
ment in the oil reservoir by which a bar, working in guides and controlled by
springs, fitted with suitable pads of leather, or other suitable material, will when
operated by handles outside the resoi voir descend, against the action of the springs,
and close the upper inlets or mouths of all the lubricators simultaneously, and
keep them closed when no feed 18 required, the handles indicating by their
horizontal position that the lubricators are closed beyond the possibility of mistake,
and when released the spings, by then reaction, aise the bar and open the inlets
of all the lubricators simultaneously the handles indicating, by their vertical
position, that they are open. Thus there is no necessity to altor the adjustment of
each lubricator, the feed being resumed as it was when shut off. The closing bar,
being directly over the mouths of the tubes, also acts as a shield to prevent dirt
entering them. The oil falls in visible drops from the lubricator "nozzles "
cups carried on a bracket below, and is conveyed by pipes to the point required.

Visible Drop Feed" Lubricators.
J, WILLIAM HOLLIDAY, of St. Kilda Terrace, Brixham, Devon, Engineer,
do hereby declare the nature of Baid invention and in what manner the same is to
be performed to be particularly described and ascertained in and by the following
statement:-
My invention is designed to obtain a perfectly reliable lubricator with "visible
drop feod," adjustable with the greatest exactness to any required extent, from the
outside, and with provision for instantly cutting off the supply when the engines
are standing and to renew it when started, in such a way as to shew distinctly
when the feed is cut off and when operating, without any excuse for negligence.
The lubricator will preferably consist of an oil reservoir fixed in some con-
veniently conspicuous position from which pipes will lead from oach feed "nozzle"
to the various parts requiring lubrication. The lubricators which project through
the bottom and into the inside of the reservoir, each consist of a tube terminating
in a tapered or invorted coned end, with small perforated holes for the issue of the
oil into the interior of a similarly inverted coued "nozzle" the upper part of which
15 "tapped" to work, when revolved by a "milled" collar, upon a fine thread cut
upon the parallel part of the tube, so that the issue of the oil through the
perforated holes can be adjusted in drops exactly to the requn omonts of the engine
or machine, and when so adjusted the "nozzle" is fixed by a winged "Jam-nut,"
inilled collar, with drilled and tapped holes to 1eceive set pins or other fixing
device which will prevent the supply varying by any vibration. In the aperture of
the perforated inner coned tube a small sorow, forming a plug, is inserted which
can at any time be removed to clean through the tubo. The nozzle being
screwed home the supply is entnely cut off, but I prefer to prevent the possibility
of waste from negligence by an arrangement in the oil reservoir by which a bai,
working in guides and controlled by spinge, fitted with suitable pads of leather, or
other suitable material, will when operated by handles outside the reservoir descend,
against the action of the springs, and close the upper inlets or mouths of all the
lubricators simultaneously, aud keep them closed when no feed is required, the
handles indicating by their horizontal position the lubricators are closed beyond
the possibility of mistake, and when released the springs, by their reaction, aise
the bar and open the inlets of all the lubricators simultaneously the handles
indicating, by the vertical position, that they are open. Thus there is no necessity
to alter the adjustment of each lubricator, the feed being resumed as it was when
shut off. The closing bar, being directly over the mouths of the tubes, also acts
as a shield to prevent dirt eutering them. The oil falls in visible drops from the
lubricator "nozzle" into cups carried on a bracket below, and is couveyed by
DIDes to the point required.

page_text: When
perforated with small holes D. for the issue of the oil and the parallel portions
of which are screwed with a fine thread to receive the external inverted coned
Dozzles E. which are tapped to be adjusted upon the threads of the tubes B, so
as to regulate the annular opening between the two cones or entirely close it
by milled collars F F, formed upon them, and provided also with small holes G.
for the insertion of set pins to further prevent the effect of vibration.
adjusted the nozzles E. are fixed to provent any variation of the annular
openings by milled collars H. acting as "jam nuts" and in addition provided with
tapped holes for the insertion of tightening set screws bearing against the threads
of the screwed tubes, or entering holes drilled therein after the "drop-feed"
has been adjusted. Should vibration by any possibility cause any shifting of the
nozzles E. downward, it can only increase the feed which will be at once dotected
by the attendant. These collars II when in position bear against the collars on
the nozzles E. and secure them firmly. The lower ends of the inuer cones C.
are closed by screwed pluga J. which aro removed when required to clean out
the oil passage.
K. is a bracket which supports the cups L. into which the oil from the nozzles
falls in visible drops and is conveyed to tho various parts requiring lubrication
by small pipes M.
Within the reservoir, working in guides N., is a flat bar O. lined on undersido
with a strip P. (of leather or other suitable material) which bar when the lubricator
is in action is raised by the external handles Q. pivoted on the ends of the
spindles R. secured at their lower ends to the bar O. and passing through guides S.
across the top of the reservoir, being lifted up against the resistance of springs T.
around the spindles R. as shewn on the drawings, the oil tubes B. now being open,
but, the handles being turned down, the action of the springs forces down the bar,
and the strip of leather closes the mouths of the tubes B., and shuts off the supply
of oil from all the nozzles entirely when not requued, as when the ongine or
machine is standing, and the "drop-feed" is again resumed without interfering
with the nozzle adjustment when the bar is raised, by again turning up the
handles, the positions of which cannot possibly be overlooked by the attendant, to
indicate to him whether the lubricator is in operation or not.
The reservoir A. when filled is closed by a hinged lid U closing down on the
rim of the box, and (where slots are cut out to allow the handles to bo operated)
upon the guides S. and so completely to exclude dust. The nozzles . are
separately adjustable to the requirements of the part to bo lubricated and any
of them may be entirely closed when not required to operate without reference to
the others, or in the event of any of the nozzles getting out of order oil may be
supplied direct to the cups L.
Having now particularly described and ascertained the nature of said inven-
tion and in what manner the same is to be performed I declare that what I
claim 18:-
1st. The improvements in "visible drop feed" lubricators, consisting of an
arrangement of double coned nozzles, one enclosing the other, the uner nozzles
being supplied from a common reservoir and perforated with holes for the passage
of the oil into an annular space between the inner and outer coues, and thenco to
fall in visible drops, adjustable as to quantity by diminishing or increasing the
annular orifice of the lips of the nozzles, effected by adjusting the outer nozzle
upon the inner nozzle and so fixing it that vibration will not affect the feed when
once adjusted substantially as described and shewn.
2nd. In combination with lubricators in which a number of parts are supplied
from one common oil reservoir, the application of means whereby the supply of
oil can be entirely suspended and resumed when required in such manner as to
indicate externally whether the lubricator is acting or not, without interfering with
the feed as then adjusted. *
3rd. The "visible-drop-feed" lubricator, consisting of the reservoir A., the

page_text: feed tubes B, the adjustable outer coned nozzles E., the "jam-nut" collars H.,
the bracket K. carrying the cups L., with pipes leading from them as required;
the flat bai O., faced with the strip P., operated by the handles Q. and springs T,
Eo as to close or open the mouths of the oil tubes, and to indicate by the position
of the handles whether closed or open, the whole forming a combination of parts
constructed and operating substantially as described and shown by the drawings
herewith.
