is adjustably mounted and the objects of my im
provements are, ?rst, to provide an adjustable ?n
ishing machine in which a ?nishing member is
provided with mechanism enabling the ?nishing
member to be adjusted with a universal move—
ment; second, to provide an adjustable ?nishing
machine having a column support and by which
10 the ?nishing member is swivelly supported, rela
tive to a horizontal plane, at a point removed
from the axis of the column support; third, to
provide a ?nishing machine having a ?nishing
member adjustably supported in an overhanging
position from an upright column support mem~
ber; fourth, to provide a ?nishing machine hav
ing a ?nishing member adjustably mounted on

It is to be understood that, whereas I show three
lever members ll at different points on my ad
justable ?nishing machine, one lever member I‘!
is adapted to ?t all of the squared ends 55, 3! and
Tl, thus making the one lever member H suitable
for operating the various shafts H, 21 and '55, as

rounding the bore of the housing as for receiving
the shaft 89 is provided with the slot 99 at one
disclosed.
The support bracket Al is provided with the
downwardly extending ?anges Bil and is further
provided- with a suitable boss portion at its upper
wall portion having the bore 86 extending there
through for receiving the bolt 82 therethrough,
the bolt 82 further extending through the bore 83
of the housing 8!! which is thus swivelly or pivo

retained by the nut $5 located between the flanges
8!; of the support bracket All.
The housing 86 is provided with the chamber

The shaft I28 is provided with the extension
portion I21 at one of its ends and upon which is
?xedly secured the pulley member i28 by the
washer I29 and the nut I30.
The shaft I23 is provided at the other of its
ends with the extension portion I 3| upon which
is mounted the ?nishing member I32 which may
be a buf?ng wheel, grinding wheel, polishing
wheel, or similar ?nishing member, the ?nishing
10 member I32 being secured by the washers I33 to
gether with the nut member l3li threadably en~
gaging the outer end of the extension portion I3I
of the shaft I23.
The electric motor assembly A is provided with
the pulley member I35 which is suitably secured
to the drive shaft I 3'5 of the electric motor as
sembly A by the nut I31, the pulley member I35
being operatively connected with the pulley mem
her 528 by the belts I39 which engage the grooves
of the pulleys I35 and I28 and thus provide driv
ing means by which the electric motor assembly
A drives the shaft I23, together with the ?nish
ing member I32. The electric motor assembly A
is further provided with- the ?ange or feet per
25 tions I 49 which are secured to the ?ange M! of
the bracket members I 52 by the screws I43 and
nuts M4. The brackets I532 are provided with
the boss portions I45 which are provided with the
bore I L35 through which extends the screws Hi1
30
which thus swivelly and pivotally support the
brackets M2 together with the electric motor ao~
sembly A and allow said bracket Hi2 and the elec
tric motor assembly A to be pivotally moved about
the axis of the screws M1 to provide means for
35 adjusting the tension on the driving belts I 39,
the screws M1 threadably engaging the cap or
cover members I I0.
In order to lock the tension of the driving belts
I 39 in their adjusted positions, one of the rack
40 ets I62 is provided with the boss I48 in which is
pivotally supported the end of the shaft or stud
I129 as at I59, the shaft hi9 extending through
a suitable opening in the rib or ?ange l5I of
the brackets I81, said rib I55 being connected
between the boss portion HI and the ?ange II5.
After the electric motor assembly A, together
with its brackets IE2, have been adjusted to their
proper position for tensioning the driving belts
I39, the shaft
is locked in place by the nuts
I52 which threadably engage the shaft use on
opposite sides of the web or flange I5I.
In order to provide further tension means for
causing the ?nishing member I32. to engage a
member to be ?nished, such as the hub cap I53
as disclosed in Fig. 10, the boss I53 is provided
with the web, lug, extension or boss portion I54
which is rigidly connected with the boss I03 and
extends into the chamber I55 formed by the hol
low or rectangular box like portion I 55 which
connects and is ?xedly secured to the brackets
I51, the boss portion i575 extending beyond and
surrounding the lug £553 of the boss I523.
The stud I51 will be suitably and ?xedly se—
cured in the lug I54 and will extend through a
65 suitable opening in the lower wall portion 153 of
the boss I56 and will be provided with the spring
or resilient member 553 which will be secured
thereon by the nut I59 threadably engaging the
outer end of the stud I51, the spring 559 thus ex—
70 erting a tension against the wall portion ‘I58 of
the boss I55 and tending to
the wall portion
I58 toward the lug I555 with a consequent down
ward movement of the ?nishing member 53?,
together with its supporting mechanism.
>
In a similar way the stud member IE! will be
suitably secured in the upper wall portion I62 of
the boss I55 and will extend through a suitable
opening in the lug I54 and if necessary through
a suitable clearance opening I63 provided in the
wall portion I56 and in a similar way the spring
or resilient member I64 will be mounted on the
outer end of the stud I6I and will be secured
thereon by the nuts I55 threadably engaging the
outer end of ‘the stud IGI and to provide for the
use of a shorter spring than would otherwise be 10
the case, the bushing or collar member I65 may
be slidably mounted on the outer end of the stud
I6! and interposed between the spring I64 and
the lug I54 to exert an effort to urge the wall
portion I92 toward the lug I51? and resulting in
a tendency to urge or move the ?nishing member
E32 and its operatively supporting parts upwardly
and swivelly or pivotally about the axis of the
screws I41.
For purposes of illustration the hub cap I53, 20
or similar member, to be ?nished, may be suit
ably mounted and retained on a supporting mem
ber I61 of a supporting or conveyor mechanism
which will support, move and feed a plurality
of the hub caps or similar members I53 past the 25
?nishing member I32.
The electric motor assembly A is provided with
a suitable electric cable I68 for connecting with
a source of electric power to operate the electric
motor assembly A.
30
In operation the electric motor assembly A will
drive the pulley member I35, which will in turn,
through the medium of the driving belts I39,
drive the pulley member I28, which in turn drives
the shaft I23 together with the ?nishing mem 35
ber I32 mounted thereon.
Due to the contour of such members as the
hub cap I53 or similar members, it is necessary
to provide various operating positions for the
?nishing member I32 and this is possible in my, 40
invention due to various adjustably mounted
and operating portions thereof. In selecting the
best operating position for thev ?nishing member
I32, as dictated by the shape or contour of the
members which are to be ?nished, the operator 45
will ?t one of the handle members I1 to the
square end I5 of the shaft II and by revolving
the shaft II with the lever member I1, the slide
5, together with its supported‘mechanism, will
be moved to the proper position which will facili
tate engagement with the. member I53 by the 50
?nishing member I32.
In order to further facilitate the position of
the ?nishing member I32, the operator may
utilize the same lever member I1 by ?tting it 55
on the square end 3! of the shaft member 21
which will enable the slide 2|, together with its
supported mechanism, to be moved in a plane
extending at right angles to the plane of move
ment of the slide 6, thus providing further ad 60
justable ability for moving the ?nishing member
I32 to its desired and required position.
‘The operator now places the lever member I1
on the square end 11 of the shaft 15 and by
operating the shaft 15, the worm 16 will operate
the worm gear 53 which will in turn drive the
shaft 56 which will cause the boss 53, together
with the collar 31 and its supported mechanism
to travel up or down the column 32 as desired,
for the positioning of the ?nishing member I32 70
relative to the work to be ?nished, the key 44
preventing the collar 31 from rotating about the
axis of the column 32.
Also in conjunction with the operation of the
shaft 15 by means of the lever I1, the screw 19 75
5
2,106,082
may be loosened to permit the housing 62 and
its supported mechanism to be rotated about the
axes of the shaft 56 and the worm 58 to provide
the desired position for best and convenient op—
eration of the lever member II on the shaft 15
by the operator.

umn mounted on and extending upwardly from
said second slide member and provided with .a
keyway extending through its side wall for the
