PROVIDIONAL SPECIFICATION.
Improved Lubricator.
1, FRANZ ANTON HUBBUCH, of Kronenburger Ring 36, Strasburg, Alsace,
Germany, Engineer, do hereby declare the nature of this invention to be as
follows:
My invention relates to an improved construction of lubricators, more particu-
larly those of small dimensions, which I will describe with reference to the accom-
panying drawings, in which Fig. 1 shews an elevation, Fig. 2 a vertical section
on line A B Fig. 1, Fig. 3 a plan and Fig. 4 a cross section on line E F Fig. 2.
The spherical oil vessel K is fixed by soldering or otherwise to the screw plug R
which is screwed into the lubricating channel of the bearing.
The central bore of the screw plug R has an inward projecting shoulder at
bottom on which rests the lower end of a helical spring f, the upper end of which
tends to press upward a small tube V, the lower end of which is guided in the
bore of the screw plug while the upper end is guided in a corresponding hole in
the top of the vessel K. A cap H closing the inlet opening of the tube V is
pivotally mounted on a pin S passing through the vessel K and through slotted
holes in the tube V. When the cap H is in the closed position shewn it is held
by the upper end of the tube projecting slightly into the tubular cavity of the cap,
the edge of the tube and of the cavity being however rounded off so that on apply-
ing a slight pressure to the cap this can be turned down in depressing the tube,
thereby uncovering the opening of the latter so that oil can be poured into it.
The tube is prevented from being pressed too far upward by the spring, by the
lower slotted holes b thereof abutting against the pin S. The oil on being poured
into the tube will be partially obstructed by the pin S so that a portion thereof will
pass through the holes b into the vessel K where it is retained, and whence it will
leak down gradually between the tube V and the bore of the plug R, thus keeping
the bearing effectually lubricated for some time.

in and by the following statement:-
My invention relates to an improved construction of lubricators, more particu-
larly those of small dimensions, which I will describe with reference to the draw-
ings accompanying my Provisional Specification, in which Fig. 1 shews an
elevation, Fig. 2a vertical section on line A B Fig. 1, Fig. 3 a plan and Fig. 4
a cross section on line E F Fig. 2. The spherical oil vessel K is fixed by soldering
or otherwise to the screw plug R which is screwed into the lubricating channel
of the bearing.
.
The central bore of the screw plug R has an inward projecting shoulder at
bottom on which rests the lower. end of a helical spring f, the upper end of which
tends to press upward a small tube V, the lower end of which is guided in the
bore of the screw plug while the upper end is guided in a corresponding hole in
the top of the vessel K. A cap H closing the inlet opening of the tube V is
pivotally mounted on a pin. S. passing through the vessel K and through slotted
holes in the tube V. When the cap H is in the closed position shewn it is held
by the upper end of the tube projectly slightly into the tubular cavity of the cap,
the edge of the tube and of the cavity being however rounded off so that on apply-
ing a slight pressure to the cap this can be turned down in depressing the tube,
thereby uncovering the opening of the latter so that oil can be poured into it.
The tube is prevented from being pressed too far upward by the spring, by the
lower slotted holes 6 thereof abutting against the pin S. The oil on being poured
into the tube will be partially obstructed by the pin S so that a portion thereof will
pass through the holes 6 into the vessel K where it is retained, and whence it will
leak down gradually between the tube V and the bore of the plug R, thus keeping
the bearing effectually lubricated for some time.
I wish it to be understood that I make no claim to the use of a pivoted cap
such as H for closing the inlet of a lubricator, as I am aware that such an arrange-
ment has already been employed.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
A lubricator wherein a tube V forming the inlet for the lubricant is supported
within the vessel by a spring in such manner that its upper projecting end acts
as spring stop for holding the pivoted cover H in the closed position, the said tube
being provided with lateral holes so arranged that on pouring in the lubricant a
portion thereof will pass into and be retained in the vessel surrounding the tube,
whence it will flow off gradually through the restricted discharge opening outside
the lower end of the tube V substantially as described.
