WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. “IMPROVEMENTS IN AXLE BOXES FOR RAILWAY
VEHICLES, AND IN LUBRICATING DEVICES FOR THE SAME AND OTHER BEARINGS."
[A communication from abroad by Thomas Haynes, of Kansas City, Missouri,
United States of America.]
This Invention relates chiefly to axle-boxes for railway vehicles, but is also
partly applicable for facilitating the lubrication of the shafts of marine engines and
other shafts.
The said Invention is chiefly designed to improve the efficiency of the apparatus
described in the first portion of the Specification of former Letters Patent dated
October 3, A.D. 1876, No. 3828, and comprises various novel features and improve-
ments of parts, as hereinafter described, whereby previous defects are remedied, and
the apparatus is rendered much more effective in practical operation than heretofore.
I employ the disc with bevelled periphery, as described in the said former
Specification, for carrying the oil from the oil-reservoir to a point above the upper
surface of the axle, and the said disc is attached to the end of the axle by means
of a screw-bolt, as heretofore, but I now provide in addition to the said screw-bolt
a pin, which projects from the disc or from a boss on the same, and enters a corre-
sponding cavity or hole provided in the axle. I also provide projections or teeth
on the outer face of the disc, the said projections being arranged around the edge
of a circular cavity in the centre of the face of the disc. I also provide a circular
plate designed to fit within this cavity in such a manner that projections or teeth
upon the bevelled edge of the inner face of this plate fit within some of the spaces
between the projections or teeth in the said cavity. There is a central hole in this

page_text: plate, which coincides with the hole in the centre of the disc, so that the screw-
bolt passes through both the plate and the disc into the axle. Through the bolt
there is a transverse aperture to receive a split pin, the upper and lower portions
of which fit within depressions in the outer face of the plate. This arrangement
affords a secure adjustable fastening, and prevents all danger of the disc becoming 5
loose on the axle. If, when the bolt is screwed up, the depressions in the face of
the plate designed to receive the split pin are not in line with the transverse
aperture in the screw-bolt, it will only be necessary to adjust the said plate, there
being no necessity to move the disc itself.
A further and important improvement consists in providing means whereby the 1
frame or yoke which holds the scraper will be effectually prevented from moving
upward too far in the event of any shock or jerk or other occurence. In the
apparatus constructed according to the said former Specification I employed a flat
bridge-piece arranged to press against a boss on the front part of the disc under
the action of a spiral spring coiled around a rod or piece extending from the
bridge-pieco to the lower part of the frame or yoke. It has however been found in
practice that the spring sometimes becomes considerably compressed by reason of a
sudden jerk, and the scraper thereby gets out of place. Therefore according to the
present Invention I make the said bridge-piece of a curved form, so as to fit the
lower portion of a boss on the inner face of the oil-disc, and there is an outward
projection at each side of the bridge-piece, which projections serve as stops for
corresponding shoulders on the frame or yoke should the latter have a tendency to
rise too bigh. This arrangement is very effective, as it allows sufficient play between
the parts for ordinary requirements, but at the same time provides means for
preventing the displacement of the scraper under any abnormal strain. I now
place the yoke or frame at the rear of tho oil-disc instead of in front of the
same.
According to the present Invention I make the scraper of a somewhat different
form to that shewn and described in the said former Specification, that is to say, I
construct the same in the form of a wedge-shaped or tapering block with an
aperture at the smaller end, within which aperture a part of the frame or yoke
fits, and the scraper and yoke are held firmly together by a bolt passing through a
bevelled tongue, which fits within an aperture with bevelled edges in the scraper
or block. The lower part of the block or scraper rests upon the oil-disc, and as
the oil is brought up from the reservoir by this disc it is removed therefrom and is
directed into an orifice provided in the frame or yoke, which orifice has a rear-
wardly projecting edge and lip so formed that the oil as it passes from the disc
strikes the edge, and is caused thereby to be directed in its proper course to a
projecting tongue lying under the orifice, and forming part of the "brass" or bush. The
oil flows from the tongue to the "brass" above the axle, and passes through apertures
in the brass to the axle. In practice I provide in the yoke or frame two of the
said orifices with projecting edges and lips, so that whether the vehicle be travelling
forwards or backwards the oil will be properly directed. The arms of the block
or scraper extend into the orifices. These orifices are considered to provide an
important improvement in the practical operation of the apparatus for the reason
that they prevent the oil from being scattered and driven off in a wrong direction.
The block or scraper is provided with a flange, which overlaps the front of the
oil disc and prevents the scraper from lateral motion inwardly.
In some cases where a long surface has to be lubricated I provide above the oil-
disc, in addition to the scraper hereinbefore described, long guides or tongues 50
arranged that the oil arriving and thrown off at the top of the disc will be caught
by them and be thereby distributed over a considerable length of shaft or axle.
The present Invention further relates to other improvements specially designed
for the axle-boxes of railway-vehicles, although partly applicable for all classes of
shafts or axles, and these improvements have for their objects to take up wear
of the dust-plate, to avoid jamming of tho "brass" or bush, to distribute wear

page_text: upon the axle or shaft and the wheels, and to provide increased bearing surface
with lightness of structure, and for the better distribution of the lubricant.
This part of my Invention comprises take-up mechanism for the dust-plate,
flange, or collar upon the inner end of the box or lubricator, the peculiar con-
struction of this flange or collar providing the “ brass" or journal with diverging
channels or passages leading from a common passage, opening, or cavity to and
down each side of the brass or bush, and obliquely arranged soft inctal plates or
blocks inserted in the "brass" or bush.
In carrying this part of any Invention into practice the axle-box is provided
at the lower side with a box or chamber, which is adapted to receive the lower
end of a dust-plato hereinafter described. The brass or bush is fitted with a cap,
and is adapted to fit and rest upon the axle. Cleats or projections on the inside
of the box hold the brass or bush in a horizontal position upon the axle or shaft.
A cap is provided with a lip inclined inwardly, and communicating with a hole in
the cap. The oil from the disc entering from the aforesaid orifices passes through
the hole in the cap upon the brass or journal. The latter, in addition to having a
broad elevation or reduced portion upon its upper surface, over which the cap fits,
and which holds the cap in place thereon, is provided with a longitudinal concavity
leading to the hole or cavity extending through the brass, and by means of which
the lubricant is conducted to the axle. I also provide two lubricant passages or
channels leading or diverging from the hole which extends through the brass, and
extending down the sides of the brass to further distribute the lubricant upon the
axle. In the brass or bush are inserted softer metal plates or blocks fitting in
oblique holes or slots therein. These plates or blocks are designed with their
holes to intercept the transmission of heat, and to lessen frictional contact and
consequence wear between the brass and axle. The obliquity of the holes and the
arrangement of the plates or blocks distribute the reduced wear between the brass
and axle. The blocks or plates are wedge-shaped or tapering, and are dropped
into their correspondinly shaped holes with their smaller ends downward, and
with the underside of the brass turned upward. After this the smaller ends of
the blocks are hammered, so as to flare them outwardly against the upper edges of
their holes, when they will be secured therein.
I provide a dust-plate, which is U-shaped, and is fitted upon the axle outside
of the inner or rear end of the axle-box, and against the same to exclude the
entrance of dust. The upper ends or legs of the dust-plate; which are bent at
right angles, are connected by heated screw-bolts to a yoke or packing device, and
a semi-circular plate fitted against the underside of the axle or shaft, and inserted
in the box or chamber. The yoke or packing device spans the space between the
legs of the dust-plate, and fits or rides upon the axle, thus serving with the semi-
circular plate below the same to connect the dust-plate to the axle. Right angled
ends of the legs of the dust-plate rest upon springs encircling bolts, and passing
through said ends of the dust-plate. It will be observed that the wear between
the dust-plate and its yoke and the axle will be automatically taken up by the
upwardly pressing springs on the bolts, thus obviating any possible entrance of
dust into the box that would be taken up and passed to the axle. By turning the
Ecrew-bolts, if necessary, in the required direction, as wear takes place between the
axle and the yoke and the underneath semi-circular plate, said wear can be taken
up and said parts thus kept snugly fitted upon. the axle or shaft. The yoke or
packing device can be cast hollow or in two parts, and the underneath semi-circular
plate with lateral extensions, and the former with a broad bearing surface resting
on the shaft or axle, while the latter may be fitted with and have fastened to it a
correspondingly shaped piece of wood, the wood being for the purpose of filling
up the space caused by the peculiar formation of the semi-circular plate.
Instead however of using wood as above described I prefer to make the semi-circular
plate with an opposite or projecting piece, and in such a manner that the broad surface
of the semi-circular piece will be brought in contact with the rear wall of the lower
chamber of the box, and on the other side I provide two ribs, which rest against

page_text: the front wall of the said chamber, all of which is to keep the semi-circular plate
in a perpendicular position. The object of the aforesaid construction is to obtain
broad bearing surfaces between said parts and axle with lightness combined.
The upper part of the aforesaid packing device or yoke is made hollow to receive
grease or other lubricating material if this should be required, and there will be an
aperture (one or more) to convey the same to the axle, and in some cases I provide
an aperture extending completely around the inner face of the packing ring, and
around the inner face of the semi-circular plate below the same, which aperture I
fill with graphite or plumbago to produce lubrication.
The packing device may be provided with one or more scrapers or lips to scrape
off any oil which might otherwise have a tendency to pass outside the box, and to
direct it into the oil chamber.
I also provide a plate with downwardly projecting arms, whose inner sides aro
provided with shoulders to rest upon meeting shoulders on the edges of the inner
end or the axle-box, while the outside edges of the plate are provided with bolt-
holes, through which the said plate is bolted to the box and its upper edge or end
with a cap or flange fitting over the upper edge of the box, making a dust or water-
tight fitting cap. The side of this cap-plato next to the wheel is provided with an
arch-shaped or semi-circular collar or flange. The collar or flange, which is cast
around the opening in the plate, through which the wheel-axle passes, is curved
with its ends beginning or disposed almost at a point on line with the side edges
of the said opening, and there gradually curved outward, and being at its upper
central portion farthest from the said opening. The primary object of this collar or
flange is to prevent the wheel with its more or less wabbling motion, causing its
axle shoulder, against which one edge of the brass or journal rests or abuts, to jam
the brass and risk the breaking of the same. The divergence of the curve of the
collar or flange is to distribute the wear over the wheel.

This Invention relates chiefly to axle-boxes for railway vehicles, but is also
partly applicable for facilitating the lubrication of the shafts of marine engines and
other shafts.
The said Invention is chiefly designed to improve the efficiency of the apparatus
described in the first portion of the Specification of former Letters Patent, dated
October 3rd, A.D. 1876, No. 3828, and comprises various novel features and
improvements of the parts as hereinafter described, whereby previous defects are
remedied, and the apparatus is rendered much more effective in practical operation
than heretofore.

Figure 11 is a rear view of a cap or plate heroinafter described.
Figure 12 is a front view of a portion of the oil-disc, shewing the method of
securing a plate or disc, hereinafter described, to the same.
In carrying this Invention into practico I employ a disc A with a bevelled
periphery as described in the said former Specification for conveying the oil from
the oil-reservoir a to a point above the upper surface of the axle b, and the said
disc A is attached to the end of the axle b by means of a screw or screw-bolt cas
heretofore, but I now provide in addition to the said screw-bolt a pin d which
projects from a boss e on the said disc, and enters a corresponding cavity or hole b¹
provided in the axle b. I also provide projections or teeth on the outer face of the
disc A, the said projections being arranged around the edge of a circular cavity in
the centre of the face of the disc A. I also provide a circular plate or disc a¹
designed to fit within this cavity in such a manner that projections or teeth a
upon the bevelled edge of the inner face of this plate or disc a¹ fit within some of
the spaces between the projections or teeth in the said cavity. There is a central
hole in this plate or disc a' which coincides with the hole in the centre of the oil-
disc A, so that the screw-bolt c passes through both the plate al and the disc A
into the axle b. Through the bolt there is a transverse aperture to receive a split
pin, the upper and lower portions of which fit within depressions in the outer face
of the plate or disc a'. This arrangement affords a secure adjustable fastening, and
prevents all danger of the disc A becoming loose on the axle b. If, when the bolt c
is screwed up, the depressions in the face of the plate a¹ designed to receive the

page_text: split pin are not in line with the transverse aperture in the screw-bolt c it will
only be necessary to adjust the said plate a¹, there being no necessity to move the
oil-disc A itself.
In
▲ further and important improvement consists in providing means whereby the
frame or yoke D, which holds the scraper B, will be effectually prevented from
moving upward too far in the event of any shock or jerk or other occurrence.
the apparatus constructed according to the said former Specification a flat bridge-
piece was employed, arranged to press against a boss on the front part of the disc A.
under the action of a spiral spring coiled around a rod or piece extending from the
bridge-piece to the lower part of the frame or yoke D. It has however been found
in practice that the spring sometimes becomes considerably compressed by reason
of a sudden jerk, and the scraper B thereby gets out of place. Therefore according
to the present Invention I make the said bridge-piece E of a curved form, as shewn
in Figure 2, so as to fit the lower portion of the boss e on the inner face of the oil-
disc A, and there is an outward projection c* at each side of the bridge-piece E,
which projections serve as stops for corresponding shoulders d*, d*, on the frame or
yoke D should the latter have a tendency to rise too high. This arrangement is
very effective, as it allows sufficient play between the parts for ordinary require-
ments, but at the same time provides means for preventing the displacement of the
scraper B under any abnormal strain. The yoke or frame D is placed at the rear
of the oil-disc A instead of in front of the same as heretofore.
According to the present Invention I make the scraper B of a somewhat different
form to that shewn and described in the said former Specification, that is to say,
I construct the same in the form of a wedge-shaped or tapering block with an
aperture b* at the smaller end, within which aperturo a part of the frame or yoke D
fits, and the scraper B and yoke D are held firmly together by a bolt f passing
through a bevelled tongue g, which fits within an aperture with bevelled edges in
the scraper or block B. The lower part of the block or scraper B rests upon the
oil-disc A, and as the oil is brought up from the reservoir a by this disc it is
removed therefrom and is directed into an orifice h or h¹ provided in the frame or
yoke D, which orifices have a rearwardly projecting edge and lip h* so formed that
the oil as it passes from the disc A strikes the edge *, and is caused thereby to be
directed in its proper course to a projecting tongue F lying under the orifices h, h¹;
the oil flows from the tongue F to the brass I above the axle b, and passes through
apertures in the brass to the axle. In practice, I provide in the yoke or frame D
two of the said orifices and h¹, so that whether the vehicle be travelling forward
or backward the oil will be properly directed. The arms of the block or scraper B
extend into the orifices h, h¹. These orifices are considered to provide an important
improvement in the practical operation of the apparatus, for the reason that they
prevent the oil from being scattered and driven off in a wrong direction.
The block or scraper B is provided with a flange d*, which overlaps the front
of the oil-disc A, and prevents the scraper B from lateral motion inwardly.
In some cases, where a long surface has to be lubricated, I provide above the
oil-disc A in addition to the scraper B long guides or tongues k, k³, so arranged
that the oil arriving and thrown off at the top of the disc A will be caught by
them, and be thereby distributed over a considerable length of shaft or axle.
These tongues are also very advantageous for distributing an increased quantity of
oil over shorter shafts running at high speeds.
The present Invention further relates to other improvements specially designed
for the axle boxes of railway vehicles, although partly applicable for all classes of
shafts or axles, and these improvements have for their objects to take up wear of
the dust-plate, to avoid the jamming of the brass, to distribute wear upon the
axle or shaft and the wheels, and to provide increased bearing surface with
lightness of structure, and for the better distribution of the lubricant.
This part of my Invention comprises take-up mechanism for the dust-plate, a
flange or collar upon the inner end of the box or lubricator, the peculiar
construction of this flange or collar, providing the brass or bearing with diverging

page_text: channels or passages leading from a common passage, opening, or cavity, to and
down each side of the brass, and obliquely arranged soft metal plates or blocks
inserted in the brass.
This part of my Invention is illustrated in Figures 4, 5, 6, 7, and 8 of the
Drawings. The axle-box G is provided at its inner end with a box or chamber Z,
adjacent to the inner face of which is arranged a dust plate K hereinafter
described. The brass I is fitted with a cap J, and is adapted to fit and rest upon
the axle b. Cleats or projections on the inside of the box G hold the brass I in a
horizontal position upon the axle or shaft b. The cap J is provided with the lip
or tongue F hereinbefore mentioned, inclined inwardly and communicating with a
hole in the cap.
The oil from the disc A entering from the aforesaid orifices h, h, passes through
the hole in the cap upon the brass I; the latter in addition to having a broad
elevation or reduced portion upon its upper surface, over which the cap J fits, and
which holds the cap J in place thereon, is provided with a longitudinal concavity p
leading to a hole or cavity q extending through the brass I, and by means of which
the lubricant is conducted to the axle b. I also provide two lubricant passages or
channels,, leading or diverging from the hole q which extends through the
brass I, and extending down the sides of the brass to further distribute the lubricant
upon the axle. In the brass I are inserted softer metal plates or blocks 8, 8¹²,
fitting in oblique holes or slots therein. These plates or blocks 8, 8', are designed
to intercept the transmission of frictional heat and to lessen frictional contact and
consequent wear between the brass I and axle b. The obliquity of the hole and
the arrangement of the plates or blocks distribute the reduced wear between the
brass and axle. The blocks or plates 8, 8², are wedge-shaped or tapering, and are
dropped into their correspondingly-shaped holes with their smaller ends downward
and with the underside of the brass turned upward. After this the smaller ends
of the blocks are hammered so as to flare them outwardly against the upper edges
of their holes, when they will be secured therein.
The dust-plate K herein before referred to is U-shaped, and is fitted upon the
axle 6 outside of the inner or rear end of the axle-box G, and against the same to
exclude the entrance of dust. The upper ends or legs of the dust-plate K, which
are bent at right anglos, as shewn, are connected by headed screw-bolts t to a
packing device composed of an upper portion or section L, and a lower portion or
section L'. The upper section L spans the space between the legs of the dust-
plate K, and fits or rides upon the axle b, thus serving with the lower section to
connect the dust-plato K to the axle b. The right angled ends or legs of the
dust-plate K rest upon springs u encircling the bolts t, and passing through the
ends of the dust-plate K. It will be observed that the wear between the dust-
plate K and its yoke and the axle will be automatically taken up by the upwardly
pressing springs u* on the bolts t, thus obviating any possible entrance of dust into
the box G that would be taken up and passed to the axle b. By turning the
screw-bolts t (if necessary) in the required direction as wear takes place between
the axle b and the upper section L, and the lower section L' of the packing device,
said wear can be taken up, and the said parts thus kept snugly fitted upon the
axle or shaft. The upper section L of the packing device can be cast hollow, as
shewn, or in two parts and the lower section L with lateral extensions; the
section L has a broad bearing surface resting on the shaft or axle, while the
section L' may be fitted with and have fastened to it a correspondingly shaped
piece of wood, the wood being for the purpose of filling up the space caused by
the peculiar formation of the lower section L'. Instead however of using wood
as above described, I prefer to make the lower section L' with an off set or
projecting piece v on each side, as shewn in the Drawings, and in such a manner
that the broad surface of this section L' will be brought in contact with the rear
wall of the lower chamber of the box G, and on the same side of the section L'as
the piece I provide two ribs w, which rest against the front wall of the said
chamber, this construction being to keep the lower section L' in a perpendicular

page_text: position. This construction enables me to obtain broad bearing surfaces between
said parts and the axle combined with lightness.
The upper part or section L of the aforesaid packing device or yoke is made
hollow, as shown, to receive grease or other lubricating material, if this should be
required, and there will be an aperture (one or more) to convey the saino to the
axle, and in some cases I provide a groove extending completely around the inner
face of this section L and around the inner face of the section L¹, which groove I
fill with graphite or plumbago to effect lubrication.
The packing device may be provided with one or more scrapers or lips to scrape
off and direct into the oil-chamber or reservoir any oil which might otherwise have
a tendency to pass outside the box G.
I also provide a plate M with downwardly extending arms, whose inner sides
are provided with shoulders to rest upon, meeting shoulders on the edges of the
inner end of the axle-box G, while the outside edges of the plate are provided with
bolt-holes, through which the said plate is bolted to the box G, and its upper edge
or end with a cap or flange N fitting over the upper edge of the box G, making a
dust or water tight fitting cap. The side of this cap-plate next to the wheel is
provided with a rib or flange O, which may be arch-shaped or semi-circular. This
rib or flange which is cast around the opening in the plate through which the
wheel-axle passes is shewn curved with its ends beginning or disposed almost at a
point in line with the side edges of the said opening and thence gradually curved
outward, and being at its upper central portion farthest from said opening. The
primary object of this rib or flange O is to prevent the wheel from causing its axle-
shoulder, against which one edge of the brass I rests or abuts, to jam the brass and
risk the breaking of the same. The divergence of the curve of the rib or flange is
to distribute the wear over the wheel.
By removing the plate M the packing device L, L', may be taken away or put
in place without removing the box from the axle.
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
