PROVISIONAL SPECIFICATION.
An Improved Lubricator.
I, FREDERICK TONGUE, of 21 Pitsford Street, Hockley, Birmingham, in the
County of Warwick, Cycle Fittings Manufacturer, do hereby declare the nature
of this invention to be as follows :-
This invention relates as hereinafter described to an improved lubricator and
consists essentially in making a lubricator in such a manner as to be entirely dust
proof. The top of each lubricator being connected to the body is not liable to
get lost.
My said invention will be particularly useful for lubricating the various parts of
cycles, but may be adapted for other similar purposes..
In carrying my said invention into practice, I make a metallic cylindrical cup to
form the body of the lubricator, the lower end terminating in a screwed boss
provided with a hole, through which passes the oil or other lubricant to the
bearing.
To the top of the body aforesaid, I fix by press tools, a cap provided with a hole
placed a little distance from the centre.
I, in like manner make a cup shaped shell a little larger than the body, and to fit
over the same loosely. I also provide a hole in the top thereof exactly in the
same position as that in the cup aforesaid. I also cut a slot intersecting about one
half of the side and about the middle of the said cup shaped shell. The side of
the body being furnished with a pin which engages in the slot, thus allowing the
cup to make a semi-circular movement around the body, the two being prevented
from becoming detached from one another by the pin.
It is obvious that the outer cup or shell covering the body of the lubricator, in
having a semi-circular movement around the same will allow the hole of one to
come opposite the other when moved in one direction which will enable the
lubricator to be supplied with oil. When the top is moved in the opposite direction,
the holes will be covered, thus preventing any dust or dirt from entering the
lubricator. The top being connected to the body cannot get lost.
In some cases it may be necessary to place the screw boss on the side of the
body, which will make the lubricator T shaped, instead of vertical, the oil hole
and slot being on the cylindrical part.
It may be necessary to provide a tongue or flap to cover the outer hole, as an
extra preventative against the dust.
Dated this 1st day of March 1893.

SPECIFICATION.
An Improved Lubricator.
1, FREDERICK TONGUE of 21 Pitsford Street, Hockley, Birmingham, in the
County of Warwick, Cycle Fittings Manufacturer 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 as hereinafter described, to an improved lubricator and
consists essentially in making a lubricator in such a manner as to be entirely dust
proof. The top of each lubricator being connected to the body is not liable to

page_text: My said invention will be particalarly useful for lubricating the various parts of
cycles, but may be adapted for other similar purposes.
In carrying my said invention into practice make a metallic cylindrical cup,
to form the body of the lubricator the lower end terminating in a screwed boss
provided with a hole through which passes the oil or other lubricant to the
bearing.
To the top of the body aforesaid, I fix by press tools a cap provided with a hole,
placed a little distance from the centre.
1, in like manner make a cup-shaped shell, a little larger than the body, and to
fit over the same loosely. I also provide a hole in the top thereof exactly in the
same position as that in the cap aforesaid. I also cut a slot intersecting about one
half of the side and about the middle of the cup-shaped shell. The side of the
body being furnished with a pin which engages in the slot thus allowing the cup to
make a semi-circular movement round the body, the two being prevented from
becoming detached from one another by the pin.
It is obvious that the outer cup or shell, covering the body of the lubricator in
having a semi-circular movement round the same will allow the hole of the one to
come opposite the other when moved in one direction, which will enable the
lubricator to be supplied with oil. When the top is moved in the opposite
direction, the holes will be covered, thus preventing any dust or dirt from entering
the lubricator. The top being connected to the body cannot get lost.
In some cases it may be necessary to place the screw boss on the side of the
body which will make the lubricator T shaped instead of vertical, the oil hole and
slot being on the cylindrical part.
It may be necessary to provide a tongue or flap to cover the outer hole as an
extra preventative against dust.
I will describe my invention in reference to the accompanying drawings, the same
letters of reference indicating similar parts throughout.
Figure 1 shows an elevation, Figure 2 a section, Figures 3 and 4 plans of my
invention.
Figures 5 and 6 show modification of my invention.
A indicates a cup constituting the body of a lubricator. B a screwed boss
provided with a hole or oil passage D. To the top of the lubricator A is fixed a
cap E provided with a hole F. G represents a shell provided with a hole H
shown in Figures 3, 4, 6.
When the lubricator is supplied with oil the shell G is moved round in the
direction of the arrow.
In Figure 4 is represented the top of lubricator with the top of the shell G
covering the hole F shown in dotted lines, and the hole H in the shell covered by
the plain part of the cap E.
When the lubricator is to be supplied with oil, the shell G is moved round in
the direction of the arrow shown in Figure 3, and the hole H of the shell G
brought opposite the hole F of the cap, thus the shell G is prevented from slipping
off the body of the lubricator A, by the pin or peg I fixed in the side thereof,
which engages in the slot K of the shell G and enables it to make a part of the
revolution round the same.
Figures 5 and 6 show a modification of a similar lubricator in which the screw
boss B is attached to the side thereof instead of the bottom.
In this arrangement the oil holes F and H are placed in the sides of the shell
and body respectively instead of in the top thereof. The covering and uncovering
of the holes, being effected in a similar manuer to the arrangement illustrated at
Figures 1, 2, 3 and 4.
Having now particularly described and ascertained the nature of my inven
tion and in what manner the same is to be performed, I declare that what I
claim is:-
The improved lubricator in which the holes F and H are capable of being

page_text: covered and uncovered by the movement of the shell G which is attached to the
body of the lubricator by the pin or peg I engaging in the slot K, constructed
and operated substantially as herein described and shown in the several figures of
the accompanying drawings.
