plate 39 by the wedge 41 between each indexing period
will be described in connection with the operation of the
honing head which is shown in FIGURES 8 and 11 of
the drawing.
The honing head consists of a casting '72, FIGURE
11, having a flanged base ‘73 for mounting on the movable
base 3, FIGURE 1. A housing '74, FIGURES 8 and
11, having a cylindrical body portion '75, is mounted
for angular movement in the casting 72 to which it is
secured by bolts 76 that extend through slots 77 of the
housing. Graduated scale 78, FIGURE 1, is provided
on the movable portion of the honing head and an arrow
79 is provided on a ?xed portion, so that the angular
position of the housing 74 can be set accurately to con
form to the angle of the face 47a of cup 47. Disposed
within the housing 74 is a shuttle arm 8t) and a pilot
stud 81 to keep honing head from ‘turning. The shuttle
is normally biased by a coil spring 124 to cause the rack
to bear down on the gear wheel 118. A pawl and ratchet
mechanism consisting of the wheel 125 having teeth that
are engaged by the pawls 12d moves the feed wheel 116
in the direction to advance the tape to the gathering reel
1% step by step as the tape is drawn underneath the
honing shoe. A garter spring 127 passes around sheave
wheels 12S and 129 to cause the reel 106 to revolve as
the tape is being fed by the feed reel 114. Guide ?ngers

ed on a shaft 84 journalled in anti-friction bearings, as
shown, and which is provided with a ?ywheel 8'5 to
smooth out the oscillating motion of the shuttle arm 8h
when acted upon by the eccentric drive member 83. A
sheave wheel 86 and a belt 37 are driven by motor 88,
FIGURE 11, at a predetermined speed. It will be noted
in FIGURE 8, that the shuttle arm 89 and the balancing
arm 81 are provided with oil seals 89 and the chamber
within which the yoke element operates is partially or
wholly ?lled with oil. Oil ducts for lubricating the
bearings being shown in, dotted lines.
Mounted on the end of the shuttle arms Sit and 81
is a slide 99 in which is mounted a bracket 91 that is
adjustable by ‘a screw 92 to any desired vertical posi
tion within the limits of the slide. Bracket 91 carries a
honing shoe 93 which is self-aligning, the shoe consisting
‘of a rectangular shaped body, as shown in FIGURE 9,
having serrations running parallel with the direction of
travel of the honing tape, as will be hereafter explained.
A block 94 that carries the honing shoe is mounted by
bolts 95 on the bracket 91 which consists of a pair of
spaced arms 96 and 97 secured by bolts that carry rollers
98, 99’ and 100.
.
i The parallel strands of tape between rollers 99 and
107 and rollers 10!) and 1111 prevent tension on the tape
as it moves back and forth with the shuttle arm move
ments.
'
The mounting and feeding of the honing tape will now
be described, the same being in the main shown in FIG
URE 8 of the drawing. The honing tape or strip desig
nated by the reference character 16H is supplied in roll
Attention is directed FIGURES 8, 9 and 10 of the
drawings which show that the honing shoe 93 has a
pin 93a by which it is mounted in the block 94 and that
the back of the honing shoe has a rubber liner 93b to
make the shoe self-aligning with the surface to be honed.
The serrations on the face of the honing shoe aid to main
tain the honing tape in alignment with its guide rollers
and in proper relation to the surface being honed. The
serrated face of the honing shoe is curved as shown in
FIGURE 10, to insure contact of the full width of the
tape with the surface being honed. The operation of the
above-described mechanism is brie?y as follows:
With the chamber of the honing head ?lled with oil
supplied through the line 135, the motor 88 is energized
to’ actuate eccentric 83 that causes the shuttle yoke 82
to be oscillated, which subjects the slide 90 and the horn
ing shoe bracket 91 to oscillatory movement. The short
'pilot stud shaft 81 oscillates with the head or slide 9%
and prevents the head from turning, thereby keeping
proper alignment of the honing shoe with the work. The
honing head, which in FIGURE 8 is shown as set at 10",
is adjusted to angularity of the bearing surface of the
roller bearing cup 47, as shown in FIGURE 8. The
honing tape is mounted on the supply, rewind and feed
mechanism, as shown and described in connection with
FIGURES 8 and 12, and the tape 101 is passed around the
guide rolls and the feed rolls in the manner shown and
described. With the feed hopper 48 ?lled with roller
bearing cups or other objects to be honed and with one of
the cups mounted on the supporting rollers 45, as shown
in FIGURE 3 and the Wedge 41 in the slot 40 of the
turret plate 39, the blank or work is ready to be honed.

18, contact of the abrasive tape with the bearing surface
of the cup 47 is momentarily broken. This enables the
