Improvements in and relating to Roller Bearings.
We, HENRY PERCY HOLT, of G, Victoria Street, in the City of Westminster,
Engineer, and MOSSBERG ROLLER BEARINGS, LIMITED, of 6, Victoria Street afore-
said, Manufacturers, do hereby declare the nature of this invention to be as
follows:-
This invention relates to roller bearings for application to axle boxes of rail-
way and other vehicles, and to shaft hangers, and for other purposes, and the
general object of the invention is to provide a simple, effective and inexpensive
construction of bearing.
The invention consists in the construction of a cage for the reception of the
rollers, in which the recesses for the rollers are drilled or milled out on one
operation and from one end of the cage leaving a strengthening flange projecting
in the interior at one end of the cage.
In its application to axle boxes for railway or other vehicles or rolling stock
the invention consists in the employment of a saddle bearing block so arranged
as to be capable of adjustment to suit the bearing surfaces of the axle and so
avoid the necessity of careful fitting; such saddle block being also arranged to
take off any lateral strain from the rollers that may be employed; while the
invention further consists in the design of bearing for axle boxes as hereafter
more particularly described.
In its application to shaft hangers the invention further consists in the
provision of a bearing casing of such a form as to be conveniently applicable upon
hanger brackets of the ordinary construction so as not to necessitate the employ-
ment of a new hanger bracket when roller bearings are to be applied.
In carrying the invention into effect the cage for the reception of the rollers
is provided as a sleeve of relatively great thickness. This cage or sleeve is bored
out to a diameter slightly greater than that of the shaft or surface upon which
it is to be mounted but in such a manner as to leave a flange at one extremity
inwardly projecting. The recesses for the reception of the rollers are then drilled
or milled; the tool commencing the operation at that end of the cage or sleeve
where the flange is provided so that thereby the flange serves to strengthen that
end of the cage and the recesses are formed of a length less than that of the cage
so that a continuous thickness of metal may be left at the end of the cage opposite
to that on which the internal flange is provided. The recesses are of a shape
corresponding to that of the rollers employed so that the rollers when introduced
from one end may slide into position and may be retained from falling out by
means of the edges of the recesses. It will be understood that in the formation
of the recesses that slots are formed on the interior and exterior of the cage or

page_text: sleeve and such slots permit the peripheries of the rollers to protrude on the
exterior and interior of the cage or sleeve so as to bear upon the shaft or spindle
and the bearing respectively, the slots being of too small a width to permit of
the rollers falling out. The recesses are closed up at their open ends by such
means as plugs provided upon a plate which may be secured to the cage or
sleeve a continuous groove may be provided upon the end of the cage or sleeve
and corresponding grooves on the plugs so that wire may be applied in the
grooves to firmly secure the plate to the cage.
In carrying the invention into effect in its application to axle boxes we provide
an axle box of cast or stamped metal with lateral guides for the reception of
the horn plates of the vehicle to which it is to be attached. The bearing end
of the axle is reduced to receive a hearing collar or sleeve, preferably of hardened
steel, which may be retained in position by means of a cap or plate which is
secured to the extremity of the axle by means of counter sunk screws or by
other means.
We provide a bearing block having lateral saddle pieces of phos-
phor bronze, or other suitable metal, which lateral saddle pieces may be affixed
to the main body of the hearing block by means of counter sunk screws or other
suitable means. The lateral saddle pieces may have their edges formed or curved
of a shape corresponding to that of the shoulder of the axle and the shoulder of
the cap at the extremity of the axle respectively, so that thereby such bearing block
may receive the lateral thrusts to which the bearing is subject in working. The
bearing block is fixed in position by means of a pin projecting from the top of the
axle box at a central point upon the top face of the bearing block so that the
block may be self-adjusting, that is to say, so that it may be capable of adjusting
itself longitudinally and laterally to suit the bearing and so as thereby not to
necessitate any careful fitting. Between the top part of the axle box and the
top of the saddle bearing block and around the più a suitable soft washer may
he provided. Longitudinal interior flanges may be provided in close proximity
with the edges of the bearing block for the purpose of firmly supporting it on
either side.
""
It will be understood that the cage containing the roller rides between the
hardened collar or sleeve and the under face of the bearing block. Any suitable
form of roller bearing may be employed, such as the well known " Mossberg
roller bearing, the rollers carrying round and being carried by a floating cage
within which the rollers are fitted so as to be capable of being retained from
falling out. The roller cage may be guided by means of lateral flanges or bear-
ing faces formed on the interior of the axle box. In order that the rollers may
be supported while passing with the cage round the axle a relatively fixed circular
bearing surface may be provided to partially surround the roller cage and the
bearing surface may be maintained in position to support the rollers by means
of springs, while the curved or circular plate forming such bearing surface may
be perforated so as to permit of free ingress and egress of oil for the purpose of
lubrication and upon the bottom surface of the axle box or at the lower part of
the circular plate an absorbent pad may be provided for the same purpose. The
axle box may be fitted with a front plate and with other usual fittings.
Instead of providing the bearing block with two lateral saddle bearing pieces
we may provide one only, and that preferably against the shoulder of the axle.
In such a case the opposite axle box may be similarly constructed with a bearing
block having one saddle bearing piece, so that the blocks upon the respective
axle boxes serve to counteract lateral thrusts and prevent the rollers from being
affected thereby. When forming the bearing block with only one lateral saddle
piece the cage may be prevented from working or falling out on the other side
by means of a segmental plate affixed to the face of the bearing block, while a
stop affixed to the axle box may be provided to prevent the outward lateral dis-
placement of the bearing block.
In carrying the invention into effect in its application to shaft hangers we
provide a bearing casing with a reduced central neck so as to be capable of being

ings. At each end of this casing recesses are provided for the reception of the

collars or rings fit. upon the shaft and may be keyed or otherwise affixed thereto.
The bearing recesses in the casing are accordingly of U section and the casing
is axially divided for the purpose of permitting of the fitting of the rings or
collars upon the shaft, and the placing of the rollers around them and within
the recesses of the casing. The neck may be formed with a central ridge or
may be otherwise formed so as to be held against lateral displacement.

Improvements in and relating to Roller Bearings.
We, HENRY PERCY HOLT, Engineer, and MOSSBERG ROLLER BEARINGS, LTD.,
both of 6, Victoria Street, in the City of Westminster, Manufacturers, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
This invention relates to roller bearings for application to axle boxes of rail-
way and other vehicles, to shaft hangers, and for other purposes, the general
object of the invention being to provide a simple, effective and inexpensive con-
struction of bearing.
The invention consists mainly in the construction of a cage for the reception
of the rollers, in which the recesses for the rollers are drilled or milled out on
one operation and from one end of the cage and sometimes leaving a strengthen-
ing Hange projecting in the interior at one end of the cage.
In the four accompanying sheets of explanatory drawings
Figures 1, 2, 3, 4, and 5 show detail views of our improved bearing and cage.
Figures 6 and 7 show an axle box arranged with roller bearings according to
our present invention,
Figures 8 and 9 show a shaft hanger with roller bearings applied thereto and
Figures 10 and 11 show our system of applying roller bearings to a connecting
rod end.
In its application to axle boxes for railway or other vehicles or rolling stock
the invention consists in the employment of a saddle bearing block so arranged
as to be capable of adjustment to suit the bearing surfaces of the axle and so
avoid the necessity of careful fitting; such saddle block being also arranged to
take off any lateral strain from the rollers that may be employed; while the
invention further consists in the design of bearing for axle boxes as hereafter
more particularly described.
In its application to shaft hangers the invention further consists in the
provision of a bearing casing of such a form as to be conveniently applicable
upon hanger brackets of the ordinary construction so as not to necessitate the
employment of a new hanger bracket when roller bearings are to applied.
In carrying the invention into effect in one manner as shown in Figures 1, 2,

page_text: 3, 4 and 5 the cage 6 for the reception of the rollers A is provided as a sleeve of
relatively great thickness. This cage or sleeve is bored out to a diameter slightly
greater than that of the shaft or surface upon which it is to be mounted and
sometimes in such a manner as to leave a flange e at one extremity inwardly
projecting. The recesses d for the reception of the rollers are then drilled, or
milled the tool commencing the operation at that end of the cage or sleeve where
the inner flange is provided so that thereby the flange serves to strengthen that
end of the cage and the recesses are formed of a length less than that of the cage
so that a continuous thickness of metal may be left at the end of the cage opposite
to that on which the internal flange is provided. The recesses d are of a shape
corresponding to that of the rollers A employed so that the rollers when intro-
duced from one end may slide, into position and may be retained from falling
out by means of the outer circumferential edges of the recesses. It will be
understood that in the formation of the recesses that slots are formed on the
interior and exterior of the cage or sleeve and such slots permit the peripheries
of the rollers to protrude on the exterior and interior of the cage or sleeve so as
to bear upon the shaft spindle or bush and the bearing respectively, as shown
in Figures 2, 4 and 5 the slots being of too small a width to permit of the rollers
falling out. The recesses we sometimes close up at their open ends by such
means as plugs which may be inserted separately within each hole or may he
carried by or formed upon a plate which may be secured to the cage or sleeve;
a continuous groove may
be provided upon the end of the cage or sleeve and
corresponding grooves on the plugs so that the wire may be applied in the
grooves to firmly secure the plate or plugs to the cage.
We
In carrying the invention into effect in its application to axle boxes as shown
in Figures 6 and 7 we provide an axle box of cast or stamped metal with ordinary
lateral guides for the reception of the horn plates of the vehicle to which it is to
be attached. The bearing end of the axle is reduced to receive a bearing collar
or sleeve e, preferably of hardened steel, which may be retained in position by
means of a cap or plate f as shown in Figures 6 and 7 which is secured to the
extremity of the axle by means of counter sunk screws for by other means.
provide a bearing block having lateral saddle pieces of phosphor bronze, or
other suitable metal, which lateral saddle pieces may be affixed to the main body
of the bearing block by means of counter sunk screws or rivets or by other
suitable means. The lateral saddle pieces may have their edges formed or curved
of a shape corresponding to that of the shoulder of the axle and the shoulder of
the cap at the extremity of the axle respectively, so that thereby such bearing
block may receive the lateral thrusts to which the bearing is subject in working.
The bearing block is fixed in position by means of a pin k projecting from the
top of the axle box at a central point upon the top face of the bearing block so
that the block may be self-adjusting, that is to say, so that it may be capable of
adjusting itself longitudinally and laterally to suit the bearing and so as thereby
not to necessitate any careful fitting. Between the top part of the axle box and
the top of the saddle bearing block and around the pink a suitable washer / may
be provided. Longitudinal interior flanges may be provided in close proximity
with the edges of the bearing block for the purpose of firmly supporting it on
either side.
"
It will be understood that the cage containing the rollers rides between the
hardened collar or sleeve e and the under face of the bearing block g. Any
suitable form of roller bearing may be employed, such as the well known "Moss-
berg roller bearing, the rollers carrying round and being carried by a floating
cage b within which, the rollers are fitted so as to be capable of being retained from
falling out. The roller cage may be guided by means of lateral flanges or bear-
ing faces formed on the interior of the axle box. In order that the rollers may
be supported while passing with the cage round the axle a relatively fixed circular
bearing surface m may be provided to partially surround the roller cage and the

page_text: bearing surface may be maintained in position to support the rollers by means
of springs, while the curved or circular plate m forming such bearing surface
may be perforated so as to permit of free ingress and egress of oil for the purpose
of lubrication and upon the bottom surface of the axle box or at the lower part
of the circular plate an absorbent pad may be provided for the same purpose.
The axle box may be fitted with a front plate and with other usual fittings.
Instead of providing the bearing block with two lateral saddle bearing pieces
we may provide one only, and that preferably against the shoulder of the axle.
In such a case the opposite axle box may be similarly constructed with a bearing
block having one saddle bearing piece, so that the blocks upon the respective
axle boxes serve to counteract lateral thrusts. and prevent the rollers from being
affected thereby. When forming the bearing block with only one lateral saddle
piece the cage may be prevented from working or falling out on the other side
by means of a segmental plate affixed to the face of the bearing block, while a
stop affixed to the axle box may be provided to prevent the outward lateral dis-
placement of the bearing block.
Into carrying the invention into effect in its application to shaft hangers as
shown in Figures 8 and 9 we provide a bearing casing o with a reduced central
neck o' so as to be capable of being carried within a shaft hanger of the ordinary
form not fitted with roller bearings. At each end of this casing recesses are
provided for the reception of the rollers and a bearing collar or ring p which
is mounted upon the shaft. The collars or rings fit upon the shaft and may
be keyed or otherwise affixed thereto. The bearing recesses in the casing are
accordingly of U section and the end of the casing is sometimes axially divided
for the purpose of permittting of the fitting of the rings or collars upon the
shaft and the placing of the rollers around them and within the recesses of the
casing. The neck may be formed with a central ridge or may be otherwise
formed so as to be held against lateral displacement. When making our bear-
ings and fittings for a casing which is not to be divided we provide retaining
plates f, which we attach to the casing by means of screws r. The
cage may be
constructed with the improved end strengthening ring as shown in Figure 1 or
it may be of the Mossberg or other ordinary type.
We apply our improved roller bearing and cage to a connecting rod end in one
convenient manner as shown in Figures 10 and 11 making the strengthening
ringe to project outwardly instead of inwardly as in Figure 1. "We may retain
the cage in position by means of end plates or rings s.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
1. In roller bearings the use of a roller cage in which the holes or openings
for carrying the rollers are drilled cut or formed from one end and such open
end being strengthened by means of a projecting or supporting ring or collar
formed upon the cage substantially as herein before described and as illustrated
in the accompanying drawings.
2. In roller bearings in which the rollers are inserted through openings or
holes left at one end of the cage, closing or filling such inserting or formation
holes or openings by independent plugs, or by plugs formed upon or attached to a
plate, substantially as herein before described and as illustrated in the accompany-
ing drawings.
3. The improvements in roller bearings for use upon shaft hangers or casings,
consisting of the provision of independent roller bearings at each end of the
hanger or casing substantially as herein before described and as illustrated in the
accompanying drawings.
4. The improvements in roller bearings for axle boxes consisting of a roller
cage which rides between a sleeve bush or collar carried upon the axle and a

page_text: bearing block provided with one or more saddle pieces, substantially as herein-
before described and as illustrated in Figures 7 and 8 of the accompanying
drawings.
