Improvements in Lubricators.
1, ARCHIBALD JOHN DAVIDSON of 6 Leighton Lane, Leeds, in the County of
York, Oil Merchant, 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 :-
This invention relates to the construction of lubricators, arranged to feed.
automatically or otherwise, applicable to engines and machinery generally, such.
lubricators being able to withstand the shocks or vibrations of such engines and
machinery without coming to pieces as heretofore.
To attain this object I form on the lower end of the framed body of the
lubricator carrying the glass cylinder, an annular flange, having a projecting rim.
with a male screw thread formed thereon, which screws into a female screw thread
provided in the upper part of the funnel, through which the lubricant passes to-
the machinery, this funnel also having an annular flange provided on its upper
part so that when both are screwed together the faces of such flanges meet forming
a joint, I then drill a small hole through both flanges whilst in this position, and.
insert a split pin therein, opening the free ends of such pin, to prevent it from.
working out, and also preventing the screwed parts unturning and coming to
pieces.
Where the body and funnel part of such lubricators are made in one piece, and
the lid is screwed thereto, I provide the top of such body with a flange in the sanie:
manner, the lid in this case having a flange thereon for the same purpose as.
described above.
In order to allow for wear of the screw threads, a number of extra holes are
provided in the flange on the funnel equidistant from the first hole and in the same
direction such parts screw together, so that on tightening the flanges, the original
hole in the flange of the body, passing the original hole in the funnel may come
opposite one of these extra holes in the flange of the funnel, when the split pin is.
inserted as before.
Instead of providing extra holes in the flange of the funnel, I may make them in
the flange on the body, but in the reverse direction, so that on screwing together,.
one of these extra holes will come opposite the original hole in the flange of the
funnel.
Referring to the annexed drawing Fig. 1. is a sectional elevation of a lubricator
in accordance with my invention Fig. 2. is a cross section showing a plan of the
flanges, Fig. 3. is part of a side view of the flanges.
The same letters are used to denote like parts in all the figures where they
occur; a, is the framed body of the lubricator, on the bottom part thereof is the
flange, b, with the projecting rim, c, with the male screw thread formed thereon,.
screwing into the funnel, d, provided with the flange, e, in the flange b, is provided
the hole, f, and in the flange e, a number of holes g, g¹, g², g*g* and 9, through the
holes and g, is inserted the split pin h, to prevent the two parts unscrewing and
coming to pieces.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is;
Lubricating apparatus in which the body of the lubricator is connected to the
funnel part thereof (or to the lid) hy screw threaded engaging parts provided with

page_text: perforations, and the two being locked together by a pin passing through oppositely
arranged perforations therein, the arrangement being such as to admit of
adjustment of the two parts to compensate for wear of the screw threads sub-
stantially as described & shewn.
