Appiicanon April 2z, 1937, serial No. 138,291
5 Claims.
My invention relates to a closure for the end
of a roller bearing and has for its principal object
a closure which is elïective but of simple construetion and which can be used to make a self-con- “
5 tained assembly of the bearing.'
Theinvention consists principally in a closure
having spaced outer cover rings and spaced inner
cover rings arranged in alinement with each other
and an annular washer or diaphragm bridging
10 the gap between two sets of cover rings and with
its ends held between the cover rings of the re
spective sets. The invention further consists in
the bearing closure and in the parts and com
binations and arrangements'of parts Hereinafter
15 described and claimed.

In the accompanying drawing,
Fig. l is a sectional view of a bearing and of
20
(clv. zas-1)
` ber so as to accommodate irregularities of manu
facture andvarlatio ns in the sizes .o_f parts.
In the construction shown in Fig. 2, >there is a
center ring 20 of the same construction as the
outer cover rings» 1, spacer rings 8 on either side
of said center rings spacing it from the outer
cover rings. Similarly there is an inner center
ringI 2| in the inner ring assembly -in ,alinement
with the outer center ring 20. There is thus pro
vided a second ann ular chamber 22 in which a
second diaphragm 2 3 is mounted.
.In the construction shown in Fig. 3, the spacer
rings are eliminated, the cover rings 30 being of
Vangular section with nested peripheral portions
3I and radial ilanges 32. 'I'he overlapping edge
portions 33 of the peripheral flange portions of
the cover rings are spun over the inside rings to
closure therefor embodying my invention;

The modification shown in Fig. 4 includes an
outer cover 40 having~ radial ilanges 4I at its
ends, a center ring 4 2 mounted therein and spacer
