set collars 16, and may be clamped to the
transverse shafts by set screws 17. The col-
lars are arranged at the sides of the brush
carrying levers and are provided with set
5 screws for engaging the transverse shafts.
The lower arms of the brush carrying levers
are provided with transversely alined open-
ings for the reception of transverse rods 18,
and they are connected by spaced links 19
10 with the rear end 20 of a longitudinal con-
necting bar 21, extending through an open-
ing 22 in the front wall of the casing into
the front extension thereof. The rear end
of the connecting bar, which is enlarged, is
i5 forked or bifurcated and is pivoted to the
links by a transverse bolt 23. The front
end of the connecting bar 21 is provided
with a slot 24 for the reception of the lower
arm of an upright actuating lever 25, ful-
20 crumed at an intermediate portion to the
platform 5 by a transverse pivot 26, and
extending through an opening 27 of the
platform. The pivot 26 is located at the
lower face of the front portion or platform
25 5 of the support and is maintained in suit-
able bearings thereof, and the lever 25 ex-
tends above and below the said platform 5.
The upper arm of the lever 25 is connected
by a pitman 29 with a crank shaft 30, jour-
30 naled in spaced bearings 31, and equipped
at its inner end with a crank element 32 to
which the pitman 29 is connected. The
crank shaft. 30 carries a gear wheel 33,
keyed or otherwise secured to the crank
35 shaft 30 and arranged between the spaced
bearings 31 and meshing with a pinion 34
of a counter-shaft 35. The counter-shaft 35,
which is also journaled in spaced bearings
36, has keyed or otherwise secured to it a
40 pulley 37, which is connected by a belt 38
with a relatively small pulley 39, mounted on
the shaft 40 of an electric motor 41, but any
other suitable motive power may be em-
ployed for operating the brush carrying
45 levers. The gearing for connecting the mo-
tor with the crank shaft may be varied to
secure the desired speed in the reciprocation
of the brushes 8, 9 and 10. When the motor
energizing circuit is closed, rotary motion
50 is communicated to the crank shaft, which,
through its connections with the brush car-
rying levers, oscillates the latter and recip-
rocates the brushes, which are mounted at
the upper ends of the brush holding levers.
55 - The brushes 8, 9 and 10 are arranged in
pairs, and three sets of brush holding levers
are employed, a pair of brushes being
mounted on each of the intermediate brush
holding levers. The outer brush holding
60 levers are provided at the inner faces of
their upper ends with recesses 42, having
undercut lower end walls and receiving the
lower beveled edges 43 of the outer brushes
8, 9 and 10, which are preferably secured to
65 the outer brush holding levers by horizontalbolts 44, or other suitable fastening devices.
The intermediate levers are provided at
both their side faces with recesses 45, which
receive the inner brushes 8, 9 and 10. The
inner brushes, which are arranged in pairs, 70
have beveled lower edges to fit the recesses
45, and are connected by top portions or
pieces 46, which are secured to the interme-
diate brush holding levers by vertical
screws 47, piercing the top portions or 75
pieces and engaging threaded openings in
the upper ends of the intermediate brush
carrying levers.
The brushes 8 and 9 are preferably
equipped with bristles, and the brushes 10 8
are provided with pads of flannel, felt, or
other polishing or buffing material, but they
may be provided with bristles similar to the
brushes 8 and 9 if desired. The bristles of
the brushes 8 and 9 are set at an inclination 85
and extend downwardly and inwardly so as
to engage the sides and project over the top
of the shoes supported by the foot rests 11.
The brushes 8, 9 and 10 are spaced apart to
operate at opposite sides of the foot rests, 90
and through the longitudinal adjustment of
the support 7, any one of the sets of brushes
8,9 and 10 may be arranged at the sides of
the foot rests in position for operating on
the shoes, and this adjustment of the brushes 95
may be effected without stopping the electric
motor, or other means that may be employed
for actuating the brush holding levers.
The longitudinal adjustment of the sup-
port is effected by means of a rack 48 and a 100
pinion 49. The rack is suitably secured to
the lower face of the longitudinal connect-
ing bar or portion of the support, but the
teeth may be formed integral therewith if
desired. The pinion 49, which meshes with 105
the rack 48, is mounted on a transverse shaft
50, journaled in suitable bearings of the
extension of the - frame and extending
through the space between the support and
the connecting bar 21, and having one end 110
projecting beyond the side of the extension
2 and equipped with a crank handle 51 by
means of which the shaft 50 may be rotated
for moving the support 7 backwardly and
forwardly. The shaft 50 is also equipped at 115
its outer end with a sprocket wheel 52, which
is connected by a sprocket chain 53 with a
sprocket wheel 54, mounted on a stub shaft
55 and connected with a hand wheel 56. The
hand wheel 56 is located at one side of the 120
casing and is in convenient reach of a seat 57.
The seat 57, which is supported by an up-
right standard 58, is arranged upon the top
of the casing centrally of the space between
the foot rests 11 and in rear of the same, so 125
that a person sitting upon the seat will be
in convenient position for placing his feet
upon the foot rests 11. The hand wheel is
provided for the purpose of enabling an
operator or demonstrator to adjust the sup- is2
