Albert Kingsbury, Greenwich, Conn, alslgnor to
Kingsbury Machine Works, Inc, Philadelphia,
2a., a corporation of Delaware
Application AIM 4. 1988, "Serial No. 94.2“
as Claims. (01. sis-1m
This invention relates to thrust bearings. and
‘ more particularly to thrust bearing! of the type
employing a plurality of tiltably mounted bearing
shoes associated with means for automatically
5 equalizing the pressure on the several shoes.
In my prior Patent No. 1,421,695, granted July
4, 1922, for Bearings, I have disclosed an equaliz
ing structure comprising a series of bridged
equalizing plates. preferably formed by cutting
10 the same as complementary sections from a ring
‘ or ring segment, said plates having rollers, dis
posed between the overlapping pcrtions thereof,
which also function to retain the plates in their
proper circumferential relationship by engage
15 ment in apertures in the wall of a channel
shaped cage ring. It is an object of this inven
tion to provide a thrust bearing with an improved
equalizing means of the type employing a bridged
series of equalizing plates having roller bearing
20 elements disposedbetween ‘the overlapping por
tions of said plates.
.
Another object of this invention is to‘provide
equalizing means of the type characterized which,
by reason of its construction and manner of oper
25 ation, minimizes the wear of the roller elements
employed, to the end that said equalizing means
will withstand a long period of service even
though the conditions of service are such as to
cause movement of each equalizing plate during
30 each rotation of the shaft.
Another object of this invention is to provide
equalizing means of the type employing a bridged
series of equalizing plates which is relatively
stable, both when the load is on the bearing
35 and when the load is removed from the bear
ing, to the end that all danger of an equalizing
plate tipping from its proper position and fail
ing to function is eliminated.
Another object of this invention is to provide
40 equalizing means of the type lust characterized
which is sensitively responsive to ?uctuations of
pressure, to the end that substantial equalization
of pressure is maintained between the‘ several
bearing shoes supported by said equalizing means,
45 and which at the same time is so constructed
that the parts tend to promptly resume a normal
position upon removal of any unbalanced force
tending to move the parts out of normal position.
Another object of this invention is to provide
60 an equalizing means of the type employing a
bridged series of equalizing plates wherein the
supporting plates of the bridged series are so
mounted that they tend to assume a position
parallel to the surface upon which they are sup
55 ported by reason of their own weight or any
pressure thereagaimt and therefore return to
such position immediately that the load is with
drawn from the bearing if, in the equitable dis
tribution of pressure caused by such load, said
supporting plates are moved out of such position. 5
Another object of this invention is to‘provide
equalizing means of the type lust characterized
wherein the supporting plates of the bridged se
ries are so mounted that they will not tip over
when the load is removed from the bearing and 10
thereby possibly interfere with their proper func
tioning when the load is restored to the bearing.
Another object of this invention is to provide
equalizing means of the type characterized which
is so constructed as to be strong and durable, l5
and yet relatively simplev and compact, to the
end that with minimum consumption of space a
highly efficient and sensitive equalization of pres
sure can be obtained between the respective shoes
of the bearing.

Other objects will appear as the description of
the invention proceeds.
