In Order to provide Sufficient driving tension in
the belts 28 as well as to provide for easy re
placement thereof the motor base 32 is preferably
adjustably mounted in the frame which may-be of
any suitable construction and which as illustrated 45
preferably comprises guide-ways 33 in one of the
rear corner posts !4 and in the support I 8, in
which guide-ways are slidably disposed guides
34 on the base 32, the base being secured in any
adjusted position by means of nuts 35 engaging 50
Studs 36 projecting thl‘ellgh elongated slots 3? in

permit the polished leather to follow the chute,
later described, as well as to provide operating
space for the propelling or feed roll 40.
The feed roll is mounted vertically below the
polishing roll I9 and is co-extensive in length
therewith. The feed roll preferably comprises a
cork-covered cylinder suitably secured to a shaft
M which, at opposite ends thereof, is journalled
in bearings 42, each of which is supported by a
base 43 slidably disposed in a guide-way 44 in one
of the supports I‘I. Secured to the right hand end
of the shaft 4I exteriorly of the frame is a rela
tively large sprocket-wheel 45 in driving engage
ment with a roller-chain 45, which chain engages
15 a small idling sprocket 41 and is driven by a small
sprocket 48 ?xed on the shaft 49 of a motor 50.
The motor 50 need only be of about three quar
ter horse power to drive the feed-roll, which has
a velocity of only about ten, (10) revolutions per
20 minute.
The feed-roll 49 is adapted to be raised and
lowered in the operation of the machine, and this
is effected by means of improved mechanism
which not only raises and permits lowering of
25 the roll but provides for an adjustable uniform
pressure on the leather being polished. The roll
the roll I9 as well as to de?ect the same toward
the return chute, later described, a kick-off brush
‘I3 is provided.
The rotary brush ‘I3 is carried by a spindle or
shaft ‘I4, which shaft is journalled at opposite
ends thereof in bearings 15 ?xed to opposite end
supports I2.
Secured to the shaft ‘I4 inwardly of the adja
cent end of the frame is a belt-wheel ‘I6 opera
tively engaged by a pair of V-belts ‘II which en 10
gage and are driven by a smaller belt wheel ‘I8
?xed to the shaft 2I inwardly of the main drive
belt-wheel 2'! carried thereby.
In order to provide sufficient driving tension in
the belts ‘II the same are engaged by an idle roll 15
‘I9 suitably journalled on a block 80 vertically
movable in a guide-way 8I in a bracket 82, the
block being retained in adjusted position by
means of a bolt 83.
In order to protect the operator against in 20
jury from ?ying particles from the roll I 9 as well
as the roll itself, a sheet metal guard 84 is suit
ably secured at the upper edge thereof as by
hinging to one of the supports I5, as indicated
at 85 in Fig. 1, and securing the lower edge there 25

The invention comprises an improved means
for returning the polished leather to the oper
30 of a bar 53 whose opposite or inner end is pivot
ally connected at 54 to an ear 55 projecting down
wardly from the support I6. Pivotally connected
at 55 to the support I6 adjacent each end there
of is a bell-crank lever 51, one arm of which is
35 pivotally connected at 58 to an adjustable link 59
and the other arm of which is pivotally con
~
ator and which, in a preferred form, comprises 30
a sheet metal chute 81 which is preferably se
cured at the upper edge thereof to one of the
supports I5, as indicated at 88, and which is
suitably secured at the lower edge thereof to a
longitudinally-disposed strip 89 adjacent the slat 35
to the respective bearings 42.
52 of the treadle 5|.
The chute 81, as is clearly illustrated in Figs.
2 and 3, is concaved toward the operator and
has su?icient inclination to permit the polished
leather to fall by gravity to the feet of the oper 40
ator. The chute 8'! is co-extensive in width with
This construction provides a simple and effi
cient means for raising the feed roll 40 into en
brush ‘I3, and is preferably provided with lateral
nected at 6!! to one end of a link BI whose oppo
site end is pivotally connected at 62 to the ad
jacent bar 53 outwardly of the pivotal connection
54.
The links 59 are pivotally connected at 63
gagement with the leather as it is pushed forward
45 on the table 38 for compressing same between the
rolls I9 and 4E! and feeding same forward during
the polishing action of the roll I9.
A coil spring 54 is preferably connected with
the treadle and the frame, as indicated in Fig. 3,
50 to normally hold the feed roll in inoperative posi
tion.
In order to provide a uniform pressure on the
leather being polished an adjustable stud E5 is
carried by the slat 52 adjacent each end thereof
55 and is adapted to _. engage a stop 66 when the
feed roll is fully elevated, as is illustrated in
Fig. 3. The studs 65 are provided with adjust
ing and securing nuts 61 and 68. In order to
effect further adjustment of the feed roll the ad
60 justable links 59 may be shortened or lengthened.
These adjustments in the feed roll actuating
means further provide for varying the pressure
on the leather for effecting different degrees of
polish as may be desired on different grades of
65 leather.
When the feed roll is in lowered or inoperative
position the chain 46 will be slack and in order
to provide su?icient driving tension in the chain
when the feed roll is in raised operative position
the idling sprocket 41 is carried by a block 69
vertically movable in a guide ‘ID in a bracket ‘II
disposed on the right-hand support I2, the block
being retained in adjusted position by means of
a bolt ‘I2.
In order to prevent adherence of the leather to
the length of the rolls I9 and 40 as well as the
guide-?anges 9B. In the operation of the con
struction disclosed the leather is placed upon the 45
table 38, whereupon the operator presses the
treadle 5| down until the studs 65 engage the
stops 66, and the feed roll 40 will, through the
linkage above described, be brought into engage
ment with the leather and will compress same 50
against the polishing roll I9 and feed the same
uniformly toward the kick-off brush ‘I3. The
kick-off brush will release the leather from the
roll I9, whereupon it will fall onto the chute 81
55
and return to the operator.
The cork-covered feed roll is not only yieldable
but affords suf?cient frictional engagement with
the leather to uniformly and consistently feed the
same forward, and the woolen disc polishing-roll
presents a highly effective ?nishing surface to 60
the leather being treated. As the feed roll rotates
only about ten ( 10) revolutions per minute while
the polishing roll rotates about eight hundred and
?fty (850) revolutions per minute or eighty-?ve
(85) times as fast as the feed roll, the surface of 65
the leather will be subjected to an effective pol
ishing action by the roll I9.
From the foregoing description, it will be seen
that the improved machine in accordance with
the present invention is highly ef?cient in opera 70
tion as well as being capable of polishing leather
rapidly, and that the machine embodies such ad
justments as to assure such efficiency in operation
even after long periods of use.
