I, ALFRED JULIUS BOULP of 111, Hatton Garden, in the County of Middlesex,
Chartered Patent Agent, do hereby declare the nature of this invention to be as
follows
-
This invention relates to improvements in lubricators and especially applicable
for use on cycle and similai beauungs The device is provided with a double
closure for preventing dust from penetrating into the beamngs, the inner closure
being effected by a plug shutting oft completely the lubricator-hole from the
bearings, while the second additional closure is formed by a cover, both the
closures being actuated, as hereinafter described by a single manipulation
i、
The lubricator consists essentially of a body preferably made in one piece and
provided with a screw-thread and is vertically-bored out so as to form a lubricant,
channel, and horizontally bored out to form a cross channel wherein a plug is
located;
the latter having a passage which, when the plug 18 in place in the
boning is adapted to be placed in line with the lubricant channel
To the plug
is secured on both sides on the outside of the body a closure-cover; when the latter
is in the horizontal position, the lubricant channel is open, while, when the cover
1s in the vertical position, by the closure of the plug which is effected by turning
the cover, the lubricant channel is doubly closed, by the plug as well as by
the cover so that dust is effectually presented from penetrating into the bearings
and the lubricant from flowing out
The double closure of the lubricant channel is effected, as already mentioned,
by a single manipulation, the plug being connected with the cover, so as to move
with it.
A spring may be arranged in the body to serve to retain the plug and, conse
quently, the cover also, in the closed or open position, and for this purpose the
plug, may if desued, have flats formed upon its surface
The advantages of this lubricating device consists, in addition to the double"
closure against the entrance of dust and the outflow of oil, in the easy cleaning
of the lubricating channel, as, after the cover has been opened, one may pushi
the cleaning instrument through the channel up to the bearings

I, ALFRED JULIUS BOULT, of 111, Hatton Garden, in the County of London,
Chartered Patent Agent, do hereby declare the nature of this invention, and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement,-
The invention relates to improvements in lubricators and is especially applicable
for use on cycle and similar bearings, and is illustrated in the accompanying diaw-
ing in a form suitable for cycle wheels and bearings The device is provided with
a double closure for preventing dust from penetrating into the bearings, the inner
closure being effected by a plug shutting off completely the lubricator hole from
the bearings, while the second additional closure is formed by a cover, both the
closures being actuated, as hereinafter described, by a single manipulation
In the accompanying diawing,
Figure 1, 1s a front elevation, and
Figures 2 and 3 are vertical sections of the lubricator in its closed and open
conditions respectively
Figure 1s a horizontal section on the line A-B Figure 1
The lubricato consists essentially of a body a preferably made in one piece,
and provided with a sciew-thread &, and is vertically bored out so as to form a
lubricant channel e, and horizontally bored out to form a cross channel d wherein
a plug is located, the latter having a passage f which, when the plug is in place
in the bong d is adapted to be placed in line with the lubricant channel e Το
the plug is secured on both sides on the outside of the body a closure-cover 9,
when the latter is in the horizontal position, as shown in Figure 3, the lubricant
channel is open, while, when the cover g is in the vertical position, as represented
in Figure 2, by the closure of the plug, which is effected by turning the covei,
the lubricant channel 18 doubly closed, z by the plug e as well as by the cover g,
so that dust is effectually prevented from penetrating into the bearings and the
lubricant from flowing out
The double closure of the lubricant-channel is effected, as already mentioned,
by a single manipulation, the plug e being connected with the cover g so as to
move with it
A sping may be arranged in the body to serve to retain the plug, and, conse-
quently, the cover also, in the closed or open position, and for this purpose the
plug may, if desired, have flats formed upon its surface
The advantages of this lubricating device consist, in addition to the double
closure against the entrance of dust and the outflow of oil, in the easy cleaning
of the lubricating channel, as, after the cover has been opened, one may push
the cleaning instrument though the channel up to the bearings
Having now particularly described and ascertained the nature of the said in-
vention as communicated to me by my foreign correspondents and in what
manner the same is to be performed I declare that what I claim 18.-
1. Alubucato providing a double closure for preventing dust from entering
and lubricant from escaping, comprising a plug with a transverse bore arranged
in a horizontal boring of the lubricator-body, and connected with a closure-cover,

page_text: the double closing or opening of the lubricator channel being performed by a
single manipulation, substantially as described
2. The complete lubricator, with or without a spring h, substantially as described
or illustrated in the accompanying drawings.
