This invention relates to a honing device for cylinders
and the like, and more particularly to a novel mounting
As shown in FIG. 1, a pair of longitudinally spaced
transverse bores 14- are formed through end portions
11 of said carrier. An additional pair of longitudinally
spaced bores are also formed through said carrier at
right angles to the bores ltd with the said bores 1d inter
secting the longitudinal bore 13 which extends through

The di?iculty was that with the wear of the abrasive
element, or the resilient element of the cylinder engaging
member, it was necessary to replace the complete cyl
inder engaging element, including the said shafts and
supporting channel.
it is therefore an object of the present invention to
provide a novel form of cylinder engaging element where
in a channel assembly is provided for holding either an
abrasive element, or a resilient element for operative
engagement with the interior of a Work surface to be
honed, and wherein the said channel element is remov

of the individual cylinder engaging elements.
For example, the bores in the carrier which receive
the shafts of the left hand cylinder engaging element 17
are arranged so as to pass upon one side of the bore 13,
whereas the opposite pair of bores adapted to receive the
shafts 736 of the right hand cylinder engaging element 17
will pass upon the opposite side of the bore 13 to pro

described.
it is a further object of the present invention to pro
