Improvements relating to Journal and other Bearings.
1
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature of
this invention to be as follows:-
This invention relates to a bearing having a metallic case or shell adapted to receive
and hold the bushing in its proper position and to an anti-friction bushing or wearing
surface which is placed in the said shell or case.
The said shell or case is so constructed that end shocks or movements of the journal
cannot injure the bushing material, metallic stops or lugs being formed on the bushing
face of the said shell or case and extending into the substance of said bushings, which
stops or lugs are adapted to receive end shocks or pressures delivered by the collars
or flanges of the axle upon the ends of the bearing.
The invention will be readily understood from the following description.
The shell or case is made in any form best adapted to the particular place or work
it is designed for, and the bushing is pressed into the said shell or case and allowed
to indurate therein. On the face of the shell or case which lies next the bushing, or
as I term it, the bushing face of the shell, I form metallic lugs or stops, which are
adapted to the two-fold purpose of holding the bushing or wearing part normally in
its said housing and also the more important part of preventing end movements or
shocks of the axle, as in railway service, from knocking the bushing end wise out of
For this purpose, I make the interior face of each of the said lugs or stops
to extend into the bushing part far enough to overlap the line of the collar or flange
of the axle.
its case.
The retaining ribs or lugs may extend to the end of the case or shell or they may
stop short of the end of the shell or they may be made sectional. In the last named
instances the bushing material covers the ends of the lugs or stops as well as their
inner faces, and thus a cushing of the bushing material is formed between the collars

page_text: of the axle and the ends of the metallic stops. This form secures better anti-friction
results, but in either case the metallic stops act to receive all the end thrusts of the
axle collars against the bushing part, and so prevent injury to the said bushing from
this cause.
The bushing is made of a plastic material having finely powdered plumbago as a
lubricating material. This lubricant, incorporated as hereinafter described, forms
a permanent, dry lubricant and needs no oil or other added lubrication while in use.
For this purpose, I take finely powdered plumbago, and mix it with about its own
weight of any suitable fibre, such as asbestos, paper pulp or any suitable woody fibre.
If, woody fibre is used it must first be prepared by soaking it in warm water or
steaming it. To these elements are added a strong size such as liquid silicate of soda
or potash, albumen, or any equivalent strongly adhesive material, and the mass is then
worked into a plastic paste which is then pressed into the shell or case and allowed
to indurate therein, and when fully dry and hard pressed into place. This bushing is
then ready for use.
For severe wear upon this bushing I add to its durability by embedding strips of
vulcanized fibre into its wearing face or surface.

page_text: I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
Southampton Buildings, in the County of Middlesex, 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 to a bearing having a metallic case or shell adapted to receive
and hold the bushing in its proper position and to an anti-friction bushing or wearing
surface which is placed in the said shell or case.
The said shell or case is so constructed that end shocks or movements of the journal
cannot injure the bushing material, metallic stops or lugs being formed on the bushing
face of the said shell or case and extending into the substance of said bushings, which
stops or lugs are adapted to receive end shocks or pressures delivered by the collars
or flanges of the axle upon the ends of the bearing.
The invention will be readily understood from the following description and the
accompanying drawings in which,
Figure 1 is an end elevation of pillar block, constructed in my improved manner,
the dotted line, a concentric with the wearing face of the bearing indicating the
periphery line of the flange or collar of the axle, and being shown clearly as overlapping
the metallic binding and thrust lugs of the shell or case.
Figure 2 is a perspective view showing the bottom side of a railway car bearing,
the concentric dotted line a, a, in this Figure also showing the contour of the thrust
rings, collars or flanges of the axle.
Figures 3 and 4 are respectively a sectional elevation and plan of a spindle, or
vertical shaft, collar or bearing.
Figure 5 is a sectional elevation through the centre of one of my improved bearings,
and an elevation of one end of the axle running therein, the dotted line ≈¹, №¹ in this
Figure indicating the bottom face of the metallic retaining lug or stop of the case,
and being clearly shown as cutting the collar and flange of the axle.
Figures 6 and 7 are modified forms of the retaining lugs or stops formed on the
bushing face of the shell or case.
The shell or case A is made in any form best adapted to the particular place or
work it is designed for, and the bushing B is pressed into the said shell or case and
allowed to indurate therein. On the face of the shell or case which lies next the
bushing, or as I term it, the bushing face of the shell, I form metallic lugs, or stops a
which are adapted to the twofold purpose of holding the bushing or wearing part
normally in its said housing, and also the more important part of preventing end
movements or shocks of the axle, as in railway service, from knocking the bushing
endwise out of its case. For this purpose, 1 make the interior face of each of the
said lugs or stops to extend into the bushing part far enough to overlap the line of
the collar or flange of the axle, as indicated by the dotted lines in Figures 1 and 2
and more fully by the dotted line ¹, x¹, and the axle drawing of Figure 5.

page_text: The retaining ribs or lugs a may extend to the end of the case or shell A as in
Figures 1, 2 and 3 or they may stop short of the end of the shell as at a¹ in Figure 2,
or they may be made sectional as in Figures 6 and 7. In the last named instances
the bushing material covers the ends of the lugs or stops as well as their inner faces,
and thus a cushion of the bushing material is formed between the collars c and ct of
the axle C, and the ends of the metallic stops a. This form secures hotter anti-friction
results, but in either case the metallic stops a act to receive all the end thrusts of the
axle collars against the bushing part and to prevent injury to the said bushing from
this cause.
The bushing B is made of a plastic material having finely powdered plumbago as a
lubricating material. This lubricant, incorporated as hereinafter described, forms
a permanent dry lubricant and needs no oil or other added lubrication while in use.
For this purpose, I take finely powdered plumbago, and mix it with about its own
weight of any suitable fibre, such as asbestos, paper pulp or any suitable woody fibre.
If woody fibre is used it must first be prepared by soaking it in warm water or
steaming it. To those elements are added a strong size such as liquid silicate of soda
or potash, albumen, or any equivalent strongly adhesive material, and the mass is then
worked into a plastic paste which is then pressed into the shell or case A and allowed
to indurate therein, and when fully dry and hard pressed into place. This bushing
is then ready for use.
For severe wear upon this bushing, I add to its durability by embedding strips D
of vulcanized fibre into its wearing face or surface, as in Figures 1, 2, 3 and 4.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, as communicated to
me by my foreign correspondent, I declare that what I claim is..
'
First A journal or other machine bearing formed of a fibrous binding material
mixed with finely powdered graphite and an adhesive material thoroughly incorporated
by mixing and pressed into a metallic casing provided with one or more lugs or stops
for holding the compound bearing material in the metallic casing.
Second A journal bearing formed of a metallic casing having ribs or lugs of the
length of the casing and an inner wearing bushing of a plastic anti-friction material
covering said ribs or lugs except at their ends, said ribs or lugs being adapted to
receive end shocks and also to hold in place the bushing material in the shell or case.
Third A journal bearing formed of a metallic casing having ribs, lugs or pro-
jections of less length than the bearing, and an inner wearing surface or bushing of
plastic anti-friction material covering and secured by said ribs or lugs whereby a
cushion is provided at the ends of the ribs or lugs adapted to receive end shocks from
the axle, substantially as described.
Fourth A journal bearing having an antifriction bushing or lining with strips of
vulcanized fibre inlaid in the said bushing, substantially as described.'
