45 Claims. (01. 51-154)
My invention relates to improvements in ?nish
ing and polishing machines of that type in which
pieces of work in rotation are carried by a re
volving turret or drum successively into contact
5 with polishing, bu?lng, or other ?nishing devices
occupying positions which are predetermined in
correspondence with the requirements of the in
dividual pieces of work to be ?nished during a
given setting of the machine.
Heretofore each polishing or ?nishing element
10
or member required independent setting and lock
ing, and as such members are often very numer
the various lines of ?nishing and polishing mem
bers are supported, whereby the machine may be
adapted for turrets of different diameters, and
for work pieces of differing diameters.
Further objects are to provide improved sup- 5
porting devices for sanding and buf?ng members;
to provide means whereby holders for the yield
ing back members associated with such sanding
or buf?ng members may be lineally adjusted in
any given series without requiring readjustment 10
of associated tensioning means; and to provide
controls at one end of the machine, whereby the
ous the setting up operation consumed consider
able time and the desired degree of accuracy was
15 not always attained.

Primary objects of this invention are to pro
vide means whereby one of the pieces of work
may be utilized to simultaneously position all ?n
ishing and polishing members of any given lineal
series and such parts associated with said mem
bers as require corresponding positioning adjust
ment, and whereby all of such members may be
simultaneously locked in their proper positions
while they are being held in such positions by
the work.
It is my object to provide means for utilizing a
piece of work to mechanically set up a machine
of the described class by adjusting such piece of
Work in a controlling position with reference to
the members requiring adjustment for such a set
ting up operation.
It is also my object to provide means whereby
the same piece of work may be successively ad
vanced from one controlling position to another
various members can be locked, released, or re
adjusted for any given line instantly and simul
taneously; and to provide means whereby each
member in any series may be independently piv
oted to a common support and adjusted either in
common or individually.

bers in any given line of working members or
elements, whereby such variations may be ac
complished simultaneously.

In all other respects the structure embodied in
this modi?cation may be assumed to be sub
stantially like that above described with reference
to Figures 1 to 6, inclusive.
In the modi?cation disclosed in Figures 11, 12,.
60 i3 and-1d the brush holders are associated for
adjusting purposes in both lineal and arcuate
' series, whereby those of several linear series at dif
ferent levels may be simultaneously adjusted from
a single piece of work. In the modi?cationillus
trated, it is not necessary that the piece of work,
should be mounted on the rotary turret or car
rier. It may be supported in a centered posi
tion upon ‘the pivoted arms I76, and these arms
may then be lifted to push‘ the work into actuat~
ing relation to a set of gauge ?ngers, each con
nected to position one of the brush holders. ‘ This
specially mounted piece of work'may thus be
utilized to mechanically position all. associated
brush holders simultaneously.
Also; in the modi?cation now to be described,
ure 1, levers I41, one for each brush holder, may "
be pivotally'mounted upon a longitudinally ex
tending pivot red I 48, this pivot rod extending .
through an intermediate portion of the_lever.. .
One arm of the lever has a rounded nose I49
which bears against the brush holder below the
brush holder pivot rod 531), whereby to angularly
position the brush.
The brush holder hook 55b
preferably has an extension 5 50 which bears upon
the upper surface of the nose portion M9of'the
lever, whereby upward movement of thisarm
of the lever will positivelyswing the brush 23b
downwardly. Movement of the lever in the op-'
posite direction will of course tend to swing'the
brush upwardly. The outer arms of the-levers
I41 are connected in an arcuate series by links
I55, whereby movement of anyone lever is trans
mitted toeach of the others in this arcuate series, 65
thereby adjusting all of the associated brushes
simultaneously in the same direction.
This adjustment 'of the levers I41 in each ar- 2
cuate series may be simultaneously accomplished
by mounting a set of controlling levers upon a
pivot rod I60. The short arms IEEI of these con;
trolling levers are slotted and receive the pivot
pins I 62 which‘connect the links I55 with the
outwardly projecting arm of one of the levers."
I41, whereby movement of the arm I6I of the 75
5
2,119,954.
controlling lever will be transmitted through the
pivot pin I52 to the lever I41 upon which it is
mounted, and through the links I55 to the other
ure 14, wherein individual collars are mounted
upon the shaft I30 and secured thereto-by set
screws I15. These collars have eccentric ?anges
levers M1 in the same arcuate series.
The controlling levers are provided with up
wardly extending arms I65 which carry con
tour testing or gauge ?ngers I56 adapted to bear
upon a piece of work A’ which has been cen
tered between supporting arms I15 secured to
an oscillatory shaft or rod I'll. As shown in
Figure 12, these controlling levers with their con
tour testing gauge ?ngers IBIS are arranged in
a longitudinally extending series upon the pivot
rod I69 and are adapted to adjust associated
15 brush holders in conformity with the contour of
the particular portion of the work with which any
given gauge ?nger I66 may contact. Levers i555
may be locked on the pivot rod Hit by means of
clamping nut I61, thereby locking all the levers
I41 in their adjusted position.
Therefore, in setting up a machine of the type
disclosed in Figures 11 and 12, a piece of work
may be centered between the supporting arms
I15 and swung upwardly into contact with the
gauge ?ngers I56, thereby adjusting all the brush
holders in conformity with the requirements of
the work. Like adjustments will be made for
each brush holder in any given arcuate series,
whereas different adjustments will be made in
each lineal series in correspondence with the
diameter of the Work against which the re
spective gauge ?ngers I55 may bear.
In machines of the type illustrated in the draw
ings, the polishing materials delivered from suc
cessive rolls 69 or 6% will ordinarily be of dif
ferent grades, the upper series of rolls 6% hav

arms I310. These arms I310 have studs 53c
with which the brush holder hooks 550 may be
engaged. Otherwise the construction of the machine may be the same as that shown in Figures
11 and 12, or if desired, it may be, the same as
that disclosed in Figures 1 ‘to 6, inclusive, if 10
these eccentrically ?anged collars are mounted
upon the rock shafts 45 disclosed in those views.
The individual adjustments made possible by the
use of separate collars I350, as shown in Figure
14, and separate pivot studs to which the brush 15
holders are hooked, as shown in'that view, may
be utilized to adapt these machines for special
duty, in which a variation in polishing pres
sure at one or more stages in the polishing op
eration becomes desirable.

In Figures 12 and 13 it will be observed that
the links I55 are arranged in pairs for mutual
reenforcement and to allow polishing strips 221)
of substantial width to occupy the space between
them. These links may be offset from each 25
other, as indicated at I11 (Fig. 13), to permit of
their connection with the uniformly spaced
brush holder adjusting levers I41. This also
facilitates access from the rear side to the levers
I41 and to the eccentric members I350 when the 30
latter are made individually adjustable.
From the foregoing description it will be un
derstood that in the form of construction dis
closed in Figures 1 to 6 the means for holding
the polishing strips to the work under the de 35
sired pressure in any given lineal series may be
simultaneously adjusted by a specimen of the

upper portions of the brush holders, thereby tilt

the extremities I49 of the levers. I 41.
In this
manner one series of brushes may be relatively
advanced or retracted to vary the resistance
which the brushes exert to the pressure of work
conveyed by the carrier along the associated pol
ishing strips.
.
With some classes of work it may be desirable
to provide for individual adjustments of the
brush holders independently of the setting of the
levers I41 and independently of the oscillatory
adjustment of the shaft ISII.
This may be ac
75 complished by the construction shown in Fig
positions. This is continued until the push rods
in each series have been so looked, after which
the machine is ready for continued operation
until the polishing strips have become sufficient 65
ly worn to require removal of the worn portions
and their replacement by advancing additional
portions of the polishing strips, either by releas
ing their clamping devices 10 (Figures 1 to 6), or
by rotating the feed rollers I41 (Figures 11 and 70
