I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester,
both in the County of Lancaster, 118, New Street, Birmingham, in the County
of Warwick, and 322, High Holborn, in the County of Middlesex, Civil
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 : —
This invention has for its object a lubricator suitable for cycles and the like,
which lubricator, as against known arrangements of the kind, is characterized
by the possibility of its remaining open through inadvertence being excluded.
For this object the lid or cover of the lubricator is pivotted on a point lying
inside said lubricator and is connected by a spring so that usually it is drawn
by the power of the spring, with its projecting edge into the closed position.
In order to introduce oil however the mouth of the oil container can be forced
between the upper edge of the lubricator and the projecting rim of the cover
in such a way that the latter is forced to one side, thereby compressing the
spring, whilst after the neck or spout of the oil can is withdrawn the cover
again springs back automatically into the closed position.
In the accompanying drawings Figures 1 to 6 show various forms of con-
struction of this improved lubricator. In the lubricator a shown in Figures 1
and 2 a rod b is pivotally mounted on a spindle c traversing the lubricator
transversely and its upper end is carried into the interior of the hollow cover
or lid d. A spiral spring e is mounted on the said rod b and bears with its
upper end against the head f of the rod b and with its lower end against the
bottom of the cover d. By the power of the said spring the cover provided with
a projecting edge or flange g is drawn downwards so that it rests on the upper
edge of the lubricator.
In order to fill the lubricator with oil the front end of the neck or spout i
of the oil can may, as shown in Figure 2. be easily inserted between the edge
and the projecting edge or flange . the lid being thus forced to one side thereby
compressing the spring e.. In this position the oil can be filled in without
difficulty, after which when the oil can is withdrawn the cover d again springs
automatically into the closing position by the pressure of the spring e
In the form of construction shown in Figures 3 and 4 the transverse spindle c
running across the lubricator a with which spindle the cover d is also pivotally

page_text: and flexibly connected, is placed, not in the lower part of the lubricator a as
shown in Figure 1, but in the upper part of the lubricator and projects through
two longitudinal slots opposite one another on a cylindrical shank or projec-
tion f attached to the underside of the cover d. Inside said projection f a
spiral spring e is located which presses with its lower end against the bottom
of the tubular projection f and with its upper end against the spindle c and
thus presses the cover d on its seat h.
If the front end i of the oil can be forced between the edge h of the lubricator
and the projecting edge or flange g of the lid, as shown in Figure 4, the lid is
inclined to one side, thus compressing the spring so that, after the filling
with oil has been completed and the oil can neck i again withdrawn, the cover
springs automatically again into its closing position.
The advantage of the lubricator shown in Figures 3 and 4 consists in the
fact that the under part of the oil container is entirely free and the space of the
same is not encroached on by any parts impeding the discharge of the oil.
The form of construction shown in Figure 5 is that of a lubricator a in which
the cover is connected with a point such as a loop piece c on the bottom of
the oil container by means of a draw spring e, and is drawn onto its seat by the
latter. By this means apart from the spring action, an all round revolubility
of the cover on the point c is attained. The introduction of oil may be effected
-in-the-same manner as shown in Figures 2 and 4 after which the cover d on
the withdrawal of the oil can is again-drawn onto its seat / by the spring e.
In the lubricator a shown in Figure 6, the cover d is connected-by-means-of
a spring with a point lying beneath the oil container, that is the bottom of a
__ projection k. For this object a link or rod b is attached to the cover and pro-
jects through the oil discharge opening and carries a perforated dise f at its
lower end. Between the latter and the bottom e a pressure -spring e is arranged
inside the chamber k and thus the lid d is drawn onto its seat h. On the inser-
tion of the oil can spout the cover is pushed aside in the manner hereinbefore
explained-and-when-said-spout is withdrawn the cover springs again into the
closing position.
Having now particularly described and ascertained the nature of the said
invention and in what manner the, same is to be performed, as communicated
to ime by my foreign correspondent, I declare that what I claim is:-
1. A lubricator for cycles and the like characterised by a cover (7) which is
pressed by the action of a spring (e) on the oil container (a) being pivotally
attached to a fixed point (c) situated lower down in the oil container (a) whereby
it is adapted to be pushed aside by the spout or neck (i) of the oil can during
the filling of the container with oil, and to spring automatically again into its
closing position upon the oil can spout being withdrawn, substantially as here-
inbefore described.
2. A form of construction of the lubricator hereinbefore described, character-
ised by the cover (d) being pivotally connected with a spring action by means
of a link or rod (6) to a spindle (c) crossing the oil container (a) transversely,
a pressure spring (e) being inserted between the upper end (projection f) of said
rod, which projects into the hollow cover (d), and the bottom of the lid to press
the cover on its seat (h) substantially as hereinbefore described and shown in
Figures 1 and 2 of the accompanying drawings.
3. A form of construction of the lubricator hereinbefore described character-
ised by the cover being pivotally connected with a spring action to a spindle (c),
traversing transversely the upper part of the oil chamber (a), by means of a
hollow cylindrical projection (f) attached to the cover, which projection engages
by means of slots (h) over the said spindle (c), a pressure spring (e) being
arranged between the bottom of the projection (f) and the spindle (c) so that
the cover is pressed by said spring on its seat (h), substantially as set forth and
shown in Figures 3 and 4,

page_text: 4. A form of construction of the lubricator hereinbefore described character-
ised by the cover (d) being connected by means of a draw spring (e) with a loop
piece (c) mounted on the bottom of the oil container (a), so as to be pulled by
said spring on its seat (h) substantially as described with reference to Figure 5
of the accompanying drawings.
