I, WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co.,
Patent Agents, Southampton Buildings, London, do horeby declare the
nature of the said Invention for "IMPROVEMENTS IN ROLLER JOURNAL BOXES,"
a communication, to be as follows :—
The said Invention relates to roller journal boxes for railway carriagos,
trucks, and waggons, and for the shafting of various kinds of machinery.
In applying the said Invention to the journal box of a railway carriage
I place around the axle journal a loose sleeve of chilled cast iron or

page_text: steel. The said sleeve passes through a cast iron cage consisting of two
hoops or rings connected by V shaped cross bars, between which are
placed the rollers. The said cage is cast in one piece, and the V shape
of the said bars allows them to be closely adapted to the form of the
rollers without diminishing their strength. On the inner side of the
said rings or hoops in the spaces between the cross bars I cast projections
with grooves opening towards the centre of the bearing for the reception
of steel pins upon which the said rollers are fitted to rotate. These
rollers are made of very hard chilled metal. A brass plug or core is
placed in the chill, and is bored to leave a light brass bushing in the
same. The rollers are inserted into the aforesaid grooves from the inside
of the bearing, and the sleeve is then inserted to keep them in place.
The cage with the rollers and sleeve is placed in the case or box, and the
journal is passed through the said sleeve.
The bearing has a cover on its outer end secured to the box by suitable 1
bolts, whose nuts are secured by locking pieces and screws. On the
inside of the said cover I place a steel plate to receive the end thrust of
the journal and sleeve. A water-tight joint between the said box and
cover is formed of lead or copper wire. The box is lubricated through
the cover. The upper part of the interior of the said box is provided ?
with a steel plate to compensate for the wear occasioned by the contact
of the rollers; or instead of using a steel plate I may chill the box for
this purpose. The said box is provided on its outside with trunnions
fitted to turn in sliding blocks, which are fitted to slide vertically in
grooves in the hangers. This method of supporting the said box permits 2
its free accommodation to any angle assumed by the journal. At the
inner ond of the journal I place around it wood packing, which is kept
in contact with the axle by spiral springs, and prevents the loss of
lubricating matter and the entrance of dust.
The application of the said journal boxes to the shaft or axle of a §

WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-seventh day of February, in the
year of our Lord Ono thousand eight hundred and soventy-three, in the
0 thirty-sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Robert Lake, Her special
licenco that I, the said William Robert Lake, my executors, adminis
trators, and assigns, or such others as I, the said William Robert Lake,
my executors, administrators, and assigns, should at any time agree with,.
5 and no others, from time to time and at all times thereafter during.
the term therein expressed, should and lawfully might make, uso,
exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for
"IMPROVEMENTS IN ROLLER JOURNAL BOXES," a communication to me from
O abroad by Seth W. Wilson, of Philadelphia, Pennsylvania, United
States of America, upon the condition (amongst others) that I, the said
William Robert Lake, my executors or administrators, by an instrument
in writing under my, or their, or one of their hands and scals, should
particularly describe and ascertain the nature of the said Invention,
5 and in what manner the same was to be performed, and causo tho.
same to be filed in the Great Seal Patent Office within six calendar
months next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said William Robert Lake, do hereby
declaro the nature of the said Invention, and in what manner the same
o is to be performed, to be particularly described and ascertained in and
by the following statement, reference being had to the accompanying
Drawings, forming a part of this Specification:-.
The said Invention relates to roller journal boxes for railway carriages,'
trucks, and wagons, and for the shafting of various kinds of machinery.
5 In applying the said Invention to the journal, of a railway carriago I
place around the axle journal a loosa metal pleovo, The said sloeve is:

page_text: surrounded by a cage consisting of two hoops or rings connected by
V shaped cross bars, between which are placed the rollers. On the inner
side of the said rings or hoops in the spaces between the cross bars I
cast projections with grooves opening toward the centre of the bearing
for the reception of steel pins, upon which the said rollers are fitted to 5
rotato.
The bearing has a cover on its outer end secured to the box by suitable
On the
bolts, whose nuts are secured by locking pieces and screws.
inside of the said cover I place a steel thumb plate to receive the end
thrust of the journal and sleeve. A water-tight joint between the said 1
box and cover is formed of lead or copper wire. The box is lubricated
through the cover. The said box is provided on its outside with
trunnions fitted to turn in blocks, which are fitted to slide vertically in
grooves in the hangers. This method of supporting the said box permits
its free accomodation to any angle assumed by the journal. At the 1
inner end of the journal I place around it wood packing, which is kept
in contact with the axle by spiral springs, and prevents the loss of
lubricating matter and the entrance of dust.
The accompanying Drawings illustrate the application of the said
improved journal box to a railway carriages, but its application to the 2
haft Ale of a machine of one kind may obviously he effected in
Figure 6 is a front view of the said box with the cover removed.

Figuro 10 is a front view of, the said box and hangers.
Figuro 11 shows the face of my improved sliding trunnion block
detached.
Figure 12 is a back view of the journal box with a portion of the
shell or caso removed to shew the interior of the same.
Figure 13 shews my improved axle packing.
A, A, are the hangers; B is a part of the carriage; O is the case or
shell of the journal box; D is its cover; E, E, are the trunnions, and
F, F, the trunnion blocks; G is the wood packing; K is the journal;
N, N, are the rings of the cage; R, R, are the connecting bars; P, P,
aro the rollers; S is the loose sleeve.
By referring to Figures 3 and 4 it will be seen that the loose sleeve S
is placed around the axle journal K. The said sleevo is formed of chilled
cast iron or steel. It passes through the cast iron cage composed of the
two annular rings N, connected by means of the V shaped cross bars R
forming chambers or pockets for receiving the rollers P. The cage con-
sisting of the said rings N and cross bars R is cast in one picco, and tho
said bars are made V shaped to permit them to be grooved without
diminishing their lateral strength. In Figure 6 it will be seen that on
the inner side of the rings N in the spaces between the cross bars R aro
cast projections V with grooved opening towards the centre for the
insertion of steel pins o upon which the rollers P revolve. The said
rollers are made of very hard chilled metal, and in their manufacture a
brass plug or coro is placed in the chill or mould. The said plug being
then drilled or bored forms a light brass bushing for the rollers P. The
said rollers are put in their position from the inside of the cage, and are
kept in place by inserting the loose sleeve S. The cage, the rollers, and
loose sleeve are placed in the case or box C, and the journal is then
passed through the said sleeve. On the inside of the cover D, as shown
in Figure 4, I place a steel thrust plate T to receive the end thrust of
both the journal K and the sleeve 8, the said plate being secured by the
rivet u. The cover D is secured to the face of the case by T headed
bolts a and lugs n. A water-tight joint is mado between the cover D
and case O by means of a lead or copper wire, as shown at e, Figure 5.

page_text: The box is lubricated through the cover D at c. The wear of the
loose travelling rollers P by their contact with the upper inside surface
of the case or box is provided for by the insertion of a steel plate T,
Figure 4, or by chilling the said case in casting the same.
By having the roller cage cast in one piece, and the two rings con- t
nected by the V shaped cross bars forming chambers between them in
combination with the trunnions E, I ensure at all times and under all
circumstances a perfect uniform line of bearing on the sleeve, the
journal, and the crown of the box or case. The rollers are guided by
the cage, and will always remain in a true line with the axle and box, 1
as the cage is kept in position longitudinaly by bosses cast on the outside
of the inner edge of the rings N, as shewn in Figure 4; therefore the
cage and rollers will not be disturbed by any longitudinal movement of
the loose sleeve. This loose sleeve protects the journal from wear, and
permits the use of journals of any size not too large to pass through the 1
said sleeve.
The trunnion E and sliding block F, shewn in Figures 11 and 12, are
of great importance. They give the box free play in the hangers A, so
that the said box may accommodate itself to any vertical angle the axlo
may assume in relation to the carriago truck or body, and they prevent 2
all strains to which the box would be otherwise subjected.
The wood packing G and the spiral spring M prevent the loss of
lubricating matter from the box and the entrance of dust into the same.
The nuts on the cover bolts a are locked by the picces L and screw
bolts b, as shewn in Figure 3. In Figures 7 and 8 H is the rigid iron 2
truck frame. In Figure 3 I have shewn an india-rubber spring Z.
Having thus fully described the said Invention as communicated to
me by my foreign correspondent, and the manner of performing the
same, I wish it understood that I claim,―
First. The trunnions E on the case O of a railway journal box in 3
combination with the sliding trunnion blocks F for the purpose
specified.
Second. The cage consisting of the rings N, V shaped connecting
bars R, and grooved projections V, forming chambers for receiving and
guiding the hollow rollers P with their stationary or loose journals o as 8
herein set forth and for the purpose specified.

page_text: Third. The loose metal sleovo S in combination with the cago N dis-
connected, extending under and supporting the said cage, slipping
loosely over the journal, and operating as herein set forth and for the
purpose specified.
Fourth. The combination of the said loose sleove, the cago, and the
hollow rollers surrounding the journal K, and enclosed within the case O,
supported in trunnions E, and provided with the thrust plate on the
cover, as herein set forth and for the purpose specified.
Fifth. In combination with the above described roller journal box
the nut locking device for securing the cover of the said box, as heroin
set forth.
Sixth. The combination of the hangers with the trunnion block sup-
porting the trunnions, and with the caso O enclosing the cage N, tho
hollow rollars P, the loose pins o, and slcovo 8, around the journal K,
as heroin set forth and for tho purpose specified.
In witness whereof, I, tho said William Robert Lake, have here.
unto set my hand and scal, this Twenty-fifth day of August,
