“Air-Way" cleaning tools of the type described
in my application for Letters Patent Serial No.

The objects of the invention are to provide an
electrically operated attachment to be connected
to the ?oor tool and operated by an electrical ex
tension cord from the motor, to improve the ac- '
15 tion of the floor tool by vibrating a portion of
the face of the tool, to make and combine an
electrical buzzer with such ?oor tool when op
erated on stationary plants; and other objects as
may appear from this speci?cation and may be
20 pointed out in the claims.
To these ends, the invention consists of the-de
sign, construction and arrangement of parts and
elements as shall ‘now be described and as are
illustrated in the drawing, in which:
Figure 1 is a plan view with sections taken on
the lines C——D and E-F of Figure 3.
Figure 2 is a reduced size view in perspective
of one end of the buzzer attachment; a similar
end being broken away.
Figure 3 shows a section taken on the line A-B
of Figure 1.'
Figure 4 is a. greatly reduced viewin perspec- ‘
springs l0, l0, which springs are to be varied
in tension by the knurled nuts H, H, according
to the power and current applied through the
coils l2, I2, etc. which may be’ wound to work
in series or in parallel, but are‘ here shown as in 15
two pairs, each pair in series but all designed
to act in unison on the common arm 5, to lugs
of which the springsv l0, l0, are-hooked at Ill’,
ID’. The portions to which the coil cores are
‘attached at l2’, I!’ are the top covers of the
encasements 8, 8, connected to the arm 5, which
not only vibrates but extendsv through under the
pipe 3 the whole length of the device, so that
clamps l3, l3 which are welded to the sides of
the encasements 8, 8, at 8', 8', will hold the
entire device ?rmly in position when the hooks
l3’, l3’ are caught over the body of the tool
and hooks l3", l3'fof'the clamps are caught
under the edge of the tool channel as shown. A
rubber guard 8" surrounds the base of encase 30
ment 8.
The vibration of the arm} of the device is
tive of an “Air-Way” cleaner with one of the _ e?ected by current from the cord H which may

Similar characters of reference refer to like
as coming from an extension ‘from the motor of 35
an “Air-Way" cleaner l5 which in turn receives
its current from a cord IS, the cords l4’ and H’
and corresponding parts in the several ?gures. _
, Referring to the drawing, the body of the
leading to the coils, being merely extensions of

is to be supplied with air suction through the
pipe 3. An "Air-way” cleaner tool is provided
with channels to hold strokers as 4 but when the
present improvement is to be used one of the

The cleaner with the attachment in place is to
be used by moving back and forth over the car

placed in the channel of the ?oor tool from which

Having thus described the invention and the
operation in the present embodiment thereof, I
do not wish to be con?ned to the details as shown
since many of them may be greatly modi?ed with
out departing from the spirit of the invention.
I claim broadly:
1. An attachment unit for a cleaning tool
having a ?oor engaging lip, comprising a casing,
an electro-magnet carried by said casing having a
vibrator arm also carried by the casing and car
spaced spring clips carried by the casing and nt
ting over the exterior of said nozzle for detach
ably connecting said supplemental unit to the.
floor tool.
6. In a pneumatic cleaner, an elongated ‘suc
rying another lip for said tool, means for de
tion nozzle, supplemental non-‘meta'llic'lip mem
tachably connecting the casing to the tool and ' bers carried by the nozzle along the longitudinal '
means for bringing electric current to the elec
edges thereof and de?ning a mouth, a vibrator
actuating unit connected to the nozzle externally
2. In combination with the floor tool of a suc
. tion cleaner having an unobstructed suction in
let, a vibrator unit detachably secured to the
floor tool comprising a casing, an electro-magnet
and vibrator arm carried by the casing, spring
15 clips for detachably connecting the casing to the
exterior of the ?oor tool, and a ?oopengaging
lip carried by the vibrator arm.
3. In combination with a suction cleaner hav
ing an elongated nozzle with an unobstructed suc
tion inlet,-a vibrator unit det'achably connected
to the nozzle externally of the suction inlet, com
prising a pair of casings each carrying an elec
tro-magnet, a common vibrator arm carried joint
lyby both of the casings, a ?oor-engaging lip
25 operated by the vibrator arm, and clamps car
ried by said casings for detachably securing said
unit to the nozzle.
4. A supplemental unit for attachment to the
?oor tool of a suction cleaner, comprising a cas~
30 ing, an electric current consuming device located
within the casing, and spring clips carried by the
casing for detachably securing the casing to the

5. In combination with a floor tool for a suc
-35 tion cleaner, having an elongated suction nozzle;
