REPAIRING METALLIC BEARINGS
Year: 1885

page_text: I, WILLIAM STRUTHERS, of N° 75 West Nile Street, Glasgow, in the County of
Lanark, North Britain, Metal Manufacturer do hereby declare the nature of the
said invention for REPAIRING METALLIC BEARINGS, to be as follows:-
"
This Invention, which relates to the repairing of metallic bearings, has for its
object to dispense with the existing process or operation of remelting worn-out
bearings by substituting for the remelting and recasting of such bearings, the
lining of the same by metal either of the same kind as that of which the bearing
itself is composed or by replacing the worn portions by a lining of another metal
so as to bring the working surfaces of the bearings back to their normal position
and dimensions.
In carrying this Invention into practice, the worn bearing is first cleansed by
heating it or otherwise treating it so as to expel or remove the oil and dirt from its
surfaces and interstices thus making the said surfaces and interstices clean.-Into
the sides and lower part of the bearing, holes are drilled or dovetailed grooves are
cut at suitable intervals across the worn surfaces or both dove-tailed grooves and
holes may be used, so that when the bearing is placed in its position in a mould
relatively with a mandril or central cylindrical body whose dimensions and position
correspond to the journal which rotates in such bearing, the metal, which is cast
into the said mould; runs into and fills the space between the inner surface of the
worn bearing and the outer surface of the said mandril and simultaneously flows
into the holes and dovetailed grooves hereinbefore mentioned or either of them, and
by means of the connections, thus formed between the lining and the worn bearing,
the lining is, when cold and solidified, thereby securely attached to the said worn
bearing.

COMPLETE SPECIFICATION.
I, WILLIAM STRUTHERS of No. 75 West Nile Street, Glasgow, in the County of
Lanark, North Britain, Metal Manufacturer do hereby declare the nature of my
said invention for REPAIRING METALLIC BEARINGS and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement:―
上
My Invention, which relates to the repairing of metallic bearings, has for its
object to dispense with the existing process or operation of remelting worn-out
bearings, by substituting for the re-melting and re-casting of such bearings, the
lining of the same by metal, either of the same kind as that of which the bearing
itself is composed, or by replacing the worn portions by a lining. of another metal
so as to bring the working or bearing surfaces of the bearings back to their, normal
position and dimensions.

In order that my said Invention may be properly understood and readily carried
into effect, I will now proceed to describe the drawings hereunto annexed."

bearing as repaired in accordance with my present Invention.

In repairing a metallic bearing a, in accordance with my present Invention, it is
first heated or otherwise treated so as to expel or remove the oil and dirt from
its surface and interstices, thus making the, said surfaces, and interstices clean.
Through the lower part and sides of the bearing a, the countersunk holes b, and c,
respectively are drilled; or dovetailed or other grooves d, and such other holes or
indentations may be used as present sufficient binding or holding surface for the
metal thereafter cast therein. The bearing, so cleansed and. otherwise, prepared, is
placed in its position in a mould relatively with a mandril or central cylindrical
body whose dimensions and relative position correspond to the journal which
rotates in such bearing. The metal, which is then cast into the said mould; runs
into and fills the space between the inner surface of the worn bearing a, and the
outer surface of the said mandril, and simultaneously flows into the holes b, and c,
and dovetailed and other grooves d, when both such holes and grooves or either of
these are provided. By means of these connections between the newly cast
lining e, and the worn bearing a, the said lining e, is, when cold and solidified,
securely attached to the said worn bearing.

page_text: Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare that what
I claim is
The repairing of metallic bearings by casting and securing thereon, a new lining
or bearing surface which metal is either the same as, or differing from that of the
original bearings and which new metal constitutes the entire bearing surface all
substantially as herein before described and shewn upon the annexed sheet of
Drawings.
