The device would normally be positioned adjacent and
opening into an oiiice or a room, `or at any place where it
is desired that the shoes be cleaned before mud which
might have been on them would be tracked into a room

holder extends not more than one-half the length of the

A primary purpose .of the invention resides in the fact
that shoes will be cleaned by a person stepping on the
brush area, whereupon the brushes will start moving to

midway of the lengths of the bodies 23, FIG. 2. A push
button Si), FIG. 9, extends upwardly from the box 49
said drive shaft causes said rock bar to reciprocate such
that said brush bodies are rocked to and fro; a motor for
driving said shaft; an electric switch having an actuating
to operate the switch therein. This switch is not shown
herein in detail other than in the diagrammatic form
in FIG. 9 since it is of the usual and conventional quick
acting type. There is an arcuate push plate fixed to the
under side of that body 23a which passes across the box
49. The button 5t) is centered centrally of the body

supporting bars 14 and 21 will return the brushes to

means comprising springs carried by the brackets, said
said elongated bodies and being located in the path of
said actuating member whereby the downward travel of
said brushes causes said actuating member to close said
switch and to energize said motor; said motor and said

Since the device will work in the wintertime to clean
snow off of shoes as well as mud and dust in the summer
time or in above freezing weather, snow dropping off of
the shoes down between the bristles 26 and the bodies
23 would normally accumulate on the ñoor 43 and freeze
thereon. ln order to overcome that freezing action, the
under side of the door 43 carries a heating element 54,
having a thermostatic element 55 in the circuit, FIG. 6,
the thermostat element 55 normally being open in weather
above a temperature of 32 degrees and closing the circuit
when the temperature drops thercbelow. Thus the licor

bristle holders frictionally retained in said grooves against

and having a lioor therein sloping toward drain means;
a grating having spaced apart bars covering the support
and above said floor; a pair of brackets, one at each side
of the box adjacent one end thereof; a second pair of
brackets spaced along the box from said end; a support
bar shiftably carried by each said pair of brackets and
confined to vertical travel; spring means carried by the
40 brackets supporting the bars at an uppermost degree of
coil 54 is also wraped around the drain tube 48 to pre

There is a grating 60 fixed over the lbox 10.
grating 60 has slots 61 therethrough deñned by the in
tervening bars 62, are coextensive With the lengths of
the brushes 26, and sufñciently wide to permit the rock
ing of the brushes 26 without hindrance from the margins
of the slots.
The guards 46 and 41 are under those
bars 62, and rock in close proximity to the bars.
Therefore it is to be seen that 1I have provided a very
simple but most effective combination for cleaning the
soles and edges thereof of shoes, with a minimum num
ber of elements, providing a `durable and comparatively
low cost device. While I have herein shown the device
in the one particular form, l do not desire to be limited
to that precise form `beyond the limitations which may
be imposed by the following claims, in View of the fact

rocker pins extending from ends of the bodies; said sup
port bars having bearings receiving said pins thereby
supporting and maintaining the spacing apart of the
bodies; a connecting bar pivotally interconnecting said
bodies at common distances from the axes of said pins;
electrical drive means longitudinally reciprocating said
connecting bar; switch means controlling said electrical
drive means; said switch means being actuated by down
travel of said bodies.
