Year: 1885

page_text: I, JAMES TENNANT, of Swillington, near Leeds, in the County of York, Farmer,
do hereby declare the nature of said invention for "AN IMPROVED LUBRICATOR
FOR THE BEARINGS OF ENGINES OR OTHER MACHINERY to be as follows:-
"
This invention has for object the economizing of fluids for lubricating the
bearings of engines or other machinery, and consists in a suitably formed vessel
(but preferably with a cylindrical interior;) of metal, glass or other suitable
material.
When made entirely of metal or when made of glass or of other suitable material,
or of such material in combination with metal, the bottom part is suitably
constructed for being attached to that part of engines or machinery requiring to
be lubricated.
The abovenamed vessel is formed with an internal annular projection at the
bottom, somewhat less in diameter than its interior, thus leaving an annular groove
between said projection and such interior. This groove forms a receptacle for any
foreign matter which may be contained in the lubricating fluid to settle down into
and which will require periodical removal.
The nozzle or neck of the lubricator by which the lubricant is supplied to a
bearing may have one or more outlets (I prefer two) which may consist of radial
slots diverging from a central threaded hole in the axis of such nozzle or neck; or
in lieu of such radial slots, separately drilled or otherwise formed holes may be
used. In a central recess in the base of the vessel and within the beforementioned
annular projection, is inserted a ring of india-rubber or other suitable material,
having openings corresponding with those in the said nozzle or neck.
This ring prevents the escape of any of the lubricating fluid at its periphery.
Upon the india-rubber or other ring is placed a metallic cup pierced in a similar
manner to the said ring and nozzle. Within this cup is placed a spiral spring or
open coil of wire, having on its upper end, in an inverted position, a similarly
shaped and pierced metallic cup to the one above referred to.
This cup may
either be provided with radial external projections or may have placed upon it a
separate and similarly pierced metallic washer so formed that while permitting
lubricating fluid to be poured into the lubricator, it may bear against its interior
and maintain the coil of wire in a central attitude therein.

page_text: The coil of wire is secured in its position by means of a central thumb-screw
taking into the threaded central hole in the nozzle previously referred to. Wires
or a wire are inserted within the coil in the direction of its axis, which pass or
passes into the outlets or outlet at the nozzle as the case may be, and used for
occasional clearing of the outlets or outlet, but in some cases may be dispensed
with.
The interior of the wire coil I pack with fibrous material, the fibres running
lengthwise thereof, this constitutes a filtering medium for the lubricating fluid as
it passes from the body of the vessel to the inside of the wire coil towards the
outlets or outlet at the nozzle or neck.
The outlet, or the quantity of lubricant used is regulated by means of the
beforenamed thumbscrew causing the coils of wire or the spring to recede from or
approach each other, as the case may be, and through the interstices of which the
lubricating fluid must pass, thus permitting a greater or less quantity to pass and
drip through the outlets or outlet as may be required and which may be so regulated
as to prevent waste.
When engines or other machinery are at rest the flow of the lubricant may be
caused to cease by turning the thumb-screw and pressing the coils of wire into close
contact with each other.
I, JAMES TENNANT, of Swillington, near Leeds, in the County of York, Farmer,
do hereby declare the nature of my said invention for "AN IMPROVED LUBRICATOR
FOR THE BEARINGS OF ENGINES OR OTHER MACHINERY" and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement :-
This invention has, for object the economical application of lubricant to the
bearings of engines or other machinery and relates to a construction of lubricator
comprising a vessel of suitable form (having as I prefer it) a cylindrical interior.
This vessel may be made entirely of metal, or of glass or other suitable material;
or partly of metal and partly of glass or other material; the bottom part being
suitably constructed for being attached to a part of an engine or other machine
requiring to be lubricated. The bottom of this vessel is formed with an internal
aunular projection somewhat less in diameter than the interior of the vessel, thus
leaving an annular groove between the projection and the wall of the vessel.

page_text: This groove forms a receptacle in which any foreign matter contained in the
lubricant can settle, such deposits being periodically. removed.
The vessel just described is provided with a nozzle or neck by which tho
lubricant is supplied to a bearing and which may have one or more outlets (I prefer
two) which may be in the form of radial slots diverging from a central threaded
hole in the nozzle or neck, or in lieu of such radial slots, separately drilled or
otherwise formed holes may be provided. In the base of the vessel and within
the beforementioned annular projection, is a recess in which is inserted a ring of
india-rubber or other suitable material having openings corresponding with those
in the nozzle or neck.
This ring prevents the escape of lubricant at its periphery. Upon the india-
rubber or other ring is placed a metallic cup pierced with holes similar to those in
the ring and nozzle Within this cup is placed one end of a spiral spring or open
coil of wire, having at its upper end, in an inverted position another metallic cup
similarly shaped and pierced to the one above referred to. This cup is provided
with radial external projections or may have placed upon it a separate and similarly
pierced metallic washer, so formed that while permitting lubricant to be poured
into the lubricator it may bear against its interior and maintain the coil of wire
in a central position, vertical grooves or projections are provided in the lubricator
for the said radial projections on the upper cup or the washer above it to take
into or on-to, so as to prevent the cup rotating when the coil of wire is being
extended or compressed as hereinafter referred to.
The coil of wire is secured in its position by means of a central thumbscrew
taking into the threaded central hole in the nozzle previously referred to. Wires
or a wire are or is inserted within the coil parallel to its axis and pass or passes
into the outlets or outlet at the nozzle as the case may be, the use of such wires or
wire is to occasionally clear the said outlets or outlet, but in some cases the wires
or wire may be dispensed with. The interior of the wire coil is packed with
fibrous material, the fibres running lengthwise thereof, this constitutes a filtering
medium for the lubricant as it passes from the body of the vessel to the inside of
the wire coil towards the outlets or outlet at the nozzle or neck. The "outlet" or
quantity of lubricant used is regulated by means of the beforenamed thumb-screw
whereby the coils or turns of wire of the spring are caused to recede from or
approach each other as the case may be, as it is between them that the lubricant
must pass, it follows that according to their distance apart a greater or less quantity
will be allowed to drip through the outlets or outlet; thus the quantity, may be so
regulated as to prevent waste.-When an engine or other machine to which such a
lubricator is applied, is at rest, the flow of lubricant may be caused to cease by
turning the thumbscrew so as to compress the spiral wire until its coils are in close
contact with each other.
In the accompanying drawings Fig. 1, is a sectional elevation of a lubricator
according to my invention. Fig. 2. is a top view. Fig. 3, a view at the lower or
nozzle end shewing the radial slots forming the outlets for the lubricant. Fig. 4, is
also a view of the lower end shewing circular outlets for the lubricant. Fig. 5, is
à horizontal section on the line 1. 2. a, is the vessel forming the reservoir of the
lubricator, b, is an annular upward projection at the bottom.
c, an annular
groove around the same for the reception of foreign matter which may be deposited
from the lubricant as previously mentioned. d, is the nozzle or neck. e, e, Figs 1.
and 3, are slots radiating from the central threaded hole e 1, for the outlet of the
lubricant. ff, Fig. 4, shew outlets of modified form for the lubricant on its way
to a bearing. g, is a ring of india-rubber or other suitable material provided with
openings corresponding with those in the nozzle, this ring fits tightly in the
recess g 1. and prevents escape of lubricant at its periphery. h, is a metallic cup
with an opening or openings corresponding with e. e, or f, f, in the nozzle as the
case may be.-i, is a coil of wire or spiral spring resting in the cup h, and j, is a
similar cup to h, but inverted. The cup j, may either have radial projections, or
a washer such as k, may be placed thereon, having radial projections k 1, k 2, each

page_text: of which may take into a groove such as l, or on to a projection such as m, as the
case may be. The recess. g 1. the cups h; and j, and the washer k, maintain the
wire coil or spring in a central position in the lubricator and the grooves or
projections l, or m, prevent the washer k, from rotating during the turning of the
thumbscrew for contracting or expanding the coil or spring as required.
The fibrous packing within the spring above referred to is not shewn in the
drawing. n, n, are wires for clearing the outlets at the nozzle in case they should
become choked up..
In lubricators of large size in which the outlets are correspondingly large, the
wires n, n, may be dispensed with.
Having now particularly described and ascertained the nature of my said.
invention and in what manner the same is to be performed, I declare that what
I claim is
1. In a lubricator, the use for regulating the escape of lubricant of a coiled wire
or spiral spring, the arrangement being such that the length and pitch of the spiral
can be varied at pleasure so as to allow more or less lubricant to pass, substantially
in the manner and for the purpose described above with reference to, and illustrated
in the drawings.
.
2. In a lubricator wherein the passage of lubricant is regulated by means of a
coiled wire or spiral spring as referred to in claim 1, the use of a cup such as h, at
the bottom of the wire coil or spring, and at the top thereof a cup such as ;,
provided with radial projections such as 1, and 2, or with a washer such as k,
having such projections, substantially as and for the purposes specified.
3. In a lubricator of the kind hereinabove referred to, forming the vessel a with
an annular projection b, and an annular groove c, substantially as for the purposes
described.
4. The lubricator constructed, arranged and operating as described above and
shewn in the drawings.
