grinding wheel may be used with various
sizes of cylinders. This angular arrange-
ment is shown in Fig. 1 in dotted lines.
In operation, the shaft 1 is adjusted with
5 respect to the shaft 21 by means of the bolts
26 and the nuts 27 and is introduced into the
cylinder. By adjusting the wheel to the
proper point any size cylinder may be
ground.
10 I claim:-
1. A cylinder grinder comprising a ho]-
low shaft, a sleeve journaled thereon and
carrying a grinding wheel at one end, a
head at the said end to which the wheel is
15 secured, a pin in the hollow shaft and ex-
tending beyond the said shaft at the head
and freely movable longitudinally of the
shaft, a collar on the pin forming one sec-
tion of a ball race, the other section being
20 secured to the sleeve, a ball bearing in the
race, and a spring between the sleeve and
the inner end of the shaft.
2. In a cylinder grinder, a sleeve cary-
ing at one end a grinding wheel, a hollow
shaft journaled in the sleeve, a pin in the 25
shaft, a ball bearing between the pin and
the sleeve, and a spring pressing the pin in
one direction to compensate for wear on the
balls of the bearing.
3. In a cylinder grinder, a grinding wheel 30
supporting shaft, a holding shaft, a sec-
tional connection for permitting the wheel
supporting shaft to extend at an angle with
respect to the holding shaft, one section of
the connection being secured to each shaft 35
and one section having the face adjacent to
the other section beveled in opposite direc-
tions from a diametrical line, tapering open-
ings in the section near the ends of the said
line, pins on the other section engaging the 40
openings, and bolts and nuts connecting the
sections, said bolts being on a line at right
angles to the first named line.
