These improvements relate to lubricators which are used in journal boxes and in
which a brush rotated by the journal distributes oil over the journal.
The said improvements consist partly in the combination with a rotary brush,
of a frame in which the same is arranged, and elliptic springs supporting the frame
and adapted to fit within a journal box with the ends in close proximity to the
ends of the box and to hold the hub of the brush in contact with the journal which
is received in the box.
The said improvements also consist partly in the combination with a rotary
brush, of a frame in which the same is arranged, elliptic springs supporting the
frame and adapted to fit within a journal box with the ends in close proximity
to the ends of the box and to hold the hub of the brush in contact with the journal
which is received in the box and semi-elliptic springs attached to the frame in such
manner that they will hog the journal and maintain the brush in proper relation
with the journal and the sides of the box.
The improvements also partly consist in the combination with a rotary brush, of
a frame in which the same is arranged, elliptic springs supporting the frame, and
adapted to fit within a journal box with the ends in close proximity to the ends

page_text: of the box, semi-elliptic springs attached to the frame in such manner that they
will hug a journal which is received in the box, rods extending between the ends
of the semi-elliptic springs, and pieces of felt and like material extending between
these rods and the elliptic springs.
The said improvements also consist partly in the combination with a rotary
brush, of a frame in which the same is arranged, elliptic springs supporting the
frame and adapted to fit within a journal box with the ends in close proximity to
the ends of the box, semi-elliptic springs attached to the frame in such manner
that they will hug the journal, and a piece of felt or like material extending
between, and depending from, the ends of the elliptic spring which is the farther
from the end of the journal.
In carrying the said invention into practice I provide a rotary brush having a
bub or body which may be made of wood, and journals which may consist of the
ends of a metal rod driven through the hub or body. Preferably the hub is made
somewhat like a spool with cylindric portions at the ends and an intermediate
portion of smaller diameter from which extend tufts of bristles. The journals of
this brush are fitted in bearings in a frame which may be made of metal and of
rectangular form. This frame is supported by elliptic springs whose leaves are united
at the ends by being made to encircle one another and prevented from disengagement
by means of bolts passing through the encircling portions. The upper leaves of
these springs may be secured to the frame by rivets or otherwise.
Elliptic springs fit in the journal box and their ends extend in close proximity
with the ends of the box, hence they cannot move far out of any position in which
they may be arranged. They support the frame in such position that the cylindric
end portions of the hub or body of the brush will be maintained in contact with
the journal Rotary motion will then be imparted to the brush by the journal.
Semi-elliptic-springs are attached between the ends by rivets or otherwise to the
frame and in such manner that they will hug the journal. Rods extend between
the ends of these springs. As these rods bear on the journal the last named springs
maintain the brush in proper position with relation to the journal and the sides of
the journal box.
As the brush rotates it picks up oil from the journal box and distributes it upon
the journal. Pieces of felt or like material extend from the rods to the lower
leaves of the elliptic springs. They may be secured to these parts by sewing or
otherwise, but care must be taken not to draw them so tight that they will
interfere with the action of the springs. They become saturated with oil and aid
in distributing it upon the journal. A piece of similar material extends between
the ends of the inner semi-elliptic spring and hugs the under side of the journal.
It serves to keep dust from the journal.
:
The advantage due to the use of the elliptic springs and the semi-elliptic springs
consists not only in their capability of maintaining the brush in its proper
position but also in the fact that they may be pressed out flat to facilitate their
insertion through. the narrow space between the journal and the opening in the
journal box. Their adjustment into position is facilitated by the rounded ends of
the elliptic spring, which, on striking the bottom of the journal box, will slide on
the same more readily than if they were sharp.or angular.

WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake, and Co Patent Agents,'
Southampton Buildings, London, IMPROVEMENTS IN LUBRICATORS FOR JOURNAL
BOXES OR BEARINGS A communication to me from abroad by Henry Rice
Randall and Charles Gibbons Till, both of Brooklyn, New York, United States of
America
This invention relate to lubricators which are used in journal boxes and in which
a brush rotated by the journal distributes oil over the same.
The said invention consists partly in the combination with a rotary brush, of a
frame in which the same is arranged, and elliptic springs supporting the said frame
and adapted to fit within a journal box with the ends in close proximity to the
ends of the said box, and to hold the hub of the brush in contact with the journal
which is received in the box.
. It also consists partly in the combination with a rotary brush, of a frame in
which the said brush is arranged, elliptic springs supporting the said frame and
adapted to fit within a journal box with the ends in close proximity to the ends of
the said box and to hold the hub of the brush in contact with the journal which is
received in the box, and semi-elliptic springs attached to the frame in such manner
that they will press upon the journal and maintain the brush in proper relation to
the said journal and the sides of the box
It also consists, partly in the combination with a rotary brush, of a frame in
which the same is arranged, elliptic springs supporting the frame and adapted to
fit within a journal box with the ends in close proximity to the ends of the said
box, semi-elliptic springs attached to the frame in such manner that they will
press upon a journal which is received in the box, rods extending between the
ends of the semi-elliptic springs, and pieces of felt or like material extending
between these rods and the elliptic springs.
It also consists partly in the combination with a rotary brush, of a frame in
which the same is arranged, elliptic springs supporting the said frame and adapted
to fit within a journal box with the ends in close proximity to the ends of the said
box, semi-elliptic springs attached to the frame in such manner that they will press
upon the journal, and a piece of felt or like material extending between, and
depending from, the ends of the elliptic spring which is the farther from the end of
the journal.
In the accompanying drawing.
Figure 1 is a sectional side elevation of a journal-box and journal, provided with
a lubricator constructed according to this invention
Figure 2 is a sectional end elevation of the same
Similar letters of reference indicate corresponding parts in both Figures.
A indicates a rotary brush, having a hub or body which may be made of wood,
and journals which, as here shown, are the ends of a metal rod driven through the
hub or body. Preferably the said hub or body is made somewhat like a spool'
with cylindric portions at the ends and an intermediate portion of smaller
diameter from which extend tufts of bristles. The journals of this brush are
fitted in bearings in a frame B which may be made of metal and of rectangular
form.
This frame B is supported by elliptic springs C, whose plates are united at the

page_text: ends by being made to encircle one another, and are prevented from disengagement
by means of bolts passing through the encircling portions. The upper plates of
these springs may be secured to the frame by rivets or otherwise.
D indicates a journal box of ordinary construction, and E indicates a journal
which is received therein. The elliptic springs C fit in this journal-box, and their
ends extend in close proximity to the ends of the said box, hence they cannot
move far out of any position in which they may be arranged. The said springs
support the frame B in such position, that the cylindric end portions of the hub
or body of the brush will be maintained in contact with the journal E. Rotary
motion will then be imparted to the brush by the journal.
G G indicate semi-elliptic springs, attached between the ends by rivets, or
otherwise, to the frame B, and in such manner that they will press upon the
journal E. Rods H extend between the ends of these springs. As these rods bear
on the journal E the springs G maintain the brush in proper position with relation
to the journal E and the sides of the journal -box.
-
As the brush rotates it picks up oil from the journal-box and distributes it upon
the journal. Pieces of felt or like material I extend from the rods H to the lower
leaves of the elliptic springs C. The said pieces of felt may be secured to these
parts by sewing or otherwise, but care must be taken not to draw them so tight
that they will interfere with the action of the springs; they become saturated with
oil and aid in distributing it upon the journal. A piece of similar material extends
between the ends of the inner semi-elliptic spring Gand, bearing against the under
side of the journal, serves to keep dust therefrom.
The advantage due to the use of the elliptic springs C and the semi-elliptic
springs G consists, not only in their capability of maintaining the brush in its
proper position, but also in the fact that they may be pressed out flat to facilitate
their insertion through the narrow space between the journal E and the opening in
the journal-box. Their adjustment into position is facilitated by the rounded ends
of the elliptic springs C which, on striking the bottom of the journal-box, will
slide on the same more readily than if they were sharp or angular.
Having thus fully described the said invention as communicated to me by my
foreign Correspondents, and the manner of performing the same I wish it understood
that I Claim:-
First. The combination with a rotary brush, of a frame in which the said brush
is arranged, and elliptic springs supporting the said frame and adapted to fit within
a journal-box with the ends in close proximity to the ends of the said box and to
hold the hub of the brush in contact with the journal which is received'in the box,
substantially as specified.
Second, The combination with a rotary brush, of a frame in which the said
brush is arranged, elliptic springs supporting the said frame adapted to fit within
a journal-box with the ends in close proximity to the ends of the said box, and to
hold the hub of the brush in contact with the journal which is received in the box,
and semi-elliptic springs attached to the frame in such manner that they will press
upon the journal and maintain the brush in proper relation to the journal and the
sides of the box, substantially as specified.
Third, The combination with a rotary brush, of a frame in which the said brush
is arranged, elliptic springs supporting the said frame and adapted to fit within a
journal box with the ends in close proximity to the ends of the said box, semi-
elliptic springs attached to the frame in such manner that they will press upon a
journal which is received in the box, rods extending between the ends of the semi-
elliptic springs, and pieces of felt or like material extending between these rods and
the elliptic springs, substantially as specified.
Fourth. The combination with a rotary brush, of a frame in which the said
brush is arranged, elliptic springs supporting the said frame and adapted to fit
within a journal-box with the ends in close proximity to the ends of the said box,,
semi-elliptic springs attached to the frame in such manner that they will press

page_text: upon the journal, and a piece of felt or like material extending between, and
depending from, the ends of the elliptic spring which is the farther from the end
of the journal, substantially as specified.
In witness whereof I the said William Robert Lake, have hereunto set my
hand and seal this twelfth day of September in the year of our Lord One
thousand eight hundred and eighty three.
