mop I5 of the endless type, a carrier I ‘I for mech
anism I6, a handle I8 for the carrier I1, and a
manually actuated operating means I9 for the
mechanism I6. There is shown a form of a
combined mop guiding and carrier supporting
element 20 which may be used in connection with
A further object of the invention is to provide,
in a manner as hereinafter set forth, an appa
ratus of the class referred to functioning as a
combined portable mop and wringer and with the
apparatus including as elements thereof a com
bined mop wringer and holder device, a carrier
for the latter, a handle for the carrier, and oper
ating means for the device supported from the
carrier and handle and actuated from a point
a water container when wringing the mop as il
lustrated in Figures 2 and 3.
The spring controlled combined mop holding v10
and wringing mechanism I6 has the mop I5 per
manently connected thereto. When a mopping
action is carried out the mop I5 is arranged in
outwardly extended relation with respect to the 15
mechanism I6. The latter includes a revoluble
outer wringer or holder roller 28. The mounting
intermediate the ends of the latter.
Further objects of the invention are to provide,
and arrangement,
ble, light in weight, compact, conveniently used
25 for mopping purposes, expeditiously operated to
provide for a wringing action on the mop, thor
oughly e?icient in its use, readily assembled and
comparatively inexpensive to manufacture.
With the foregoing and other objects in view,
30 the invention consists of the novel construction,
combination and arrangement of parts as will

A wringer mop apparatus in accordance with
to the rolls for the pur
pose of disposing mop I5 in outwardly extended
relation with respect to the mechanism I6. The
clamping function of roll 29 is transmitted from
the structure 30. The cavities 36 function to
member 51 and is formed in proximity to its lower
assist in the clamping of the mop to mechanism
l6, due to the fact that spaced portions of the
body part of the mop will be forced into several
of the cavities when the mop is clamped to mech
anism l6. When the mop is to be subjected to a
wringing action, the pressure on roll 29 is relieved
to the desired extent to permit of a stretch of
the body part of the mop being successively com
pressed for expelling the water to the desired
10 extent and for said stretch to be moved inwardly
or outwardly with respect to the rolls.
The compression structure 36 of the mechanism
I6 includes a pair of vertically adjustable spaced
parallel slides 4|, 42 which are slidably arranged
15 on the outer faces of the lower portions 43, 44
respectively of the sides 45, 46 respectively of the
carrier l1. The lower portions of the’ sides of the
carrier H are slotted as at 41 and such slots
extend from a point removed from the lower ends
of said lower portions to above the upper ends of
the latter. The slides 4|, 42 extend across the
slots 41 in the side portions 43, 44, as well as
extending slightly below the bottom of said slots.
The slide 4| is formed with an opening 48 and an
opening 48 below and aligning with the opening
Integral with the inner face of slide 4| and
registering with the openings 48,49 are inwardly
extending ?anged bearings 48a‘, 49a respectively
which pass through the slot 41 of and slidably
connect the slide 4| to carrier side 45. The ends
of the roll 29 and the caps 31 on such ends are
countersunk. The countersink at one end of roll
29 has mounted therein the bearing 49a.
Positioned against the outer face of the slide 4|,
35 as well as being suitably secured to slide 4| for the
purpose of bodily moving with the latter is a cas
ing 56 having arranged in the upper portion
thereof a gear wheel 5| which meshes with and
end with an annular peripheral groove 65 in
which is seated member 51 whereby the latter is
connected to rod 62 above the lower end of the
nut. The adjusting of the nut 64 towards the
lower end of rod 62 increases the tension of mem
ber 51 and an increase of pressure against the
upper ends of slides 4|, 42 which in turn will
transmit such pressure to roll 29 to tightly clar'np lo
mop |5 to mechanism l6. The upper end of the
rod 62 is offset as at 66 to provide a clearance for
a transmission shaft, to be referred to, of the
operating means for the mechanism l6. The
offset portion 66 of the rod 62 has its upper part
61 extended into the handle l8 and also into the
body of the latter as at 68. The part 61 is
anchored to handle |8 as at 66. The member 51
is of arcuate contour. The slide 42 is formed with
an opening 16 and extending through and integral 20
with the wall of opening 16 is a ?anged bearing
1| which passes through the slot 41 in side portion
44 and slidably connects slide 42 to carrier side 46,
The shaft 39 revolves in bearing 1| and is bodily
carried therewith when the slide 42 shifts in oppo
site directions simultaneously when the slide 4| is
shifted in like directions. The bearing 1| extends
into the countersink at the other end of roll 29.
The lower portion 43 of the side 45 of the carrier
H is formed with a key-hole shaped opening 12
for receiving the reduced portion 13 of the shaft
33 for the purpose of removably connecting the
end 13a of shaft 33 to one side of the carrier H.

inner part of hub 53 extends through the bearing
48a. The hub 53 is ?xedly secured to a polygonal
shaped driven shaft 56 for operating gear 5|.
shaft 56 extends inwardly from slide 4|. The
hub 54 of gear wheel 52 is ?xedly secured to the
shaft 38. Flanged bearings 56a are used for the
outer portions of the hubs 53, 54.
The structure 36 includes a resilient pressure
55 applying or spring member 51 of skeleton form
provided with reduced ends 58, 59. A means to
prevent the spreading of thereduced end 58 is
bearing 15 registering with the opening 14. The
shaft 33 extends through bearing 15 and the lower
side portion 44. The shaft 33 at its other end is
enlarged as at 16 to provide a head abutting the
outer face of portion 44 of the carrier H. The
head 16, in connection with the reduced portion
13 and opening 12 act to detachably connect shaft
33 to the carrier IT. The bearing extends into
axial bore 3| of roll 28. The cap at the other end
of roll 28 is formed with an inwardly extending
tubular bearing 18 which registers with the axial
opening thereof and extends into the axial bore 3|
of roll 28. The bearing 18 is arranged in endwise
alignment with the bearing 15. The shaft 33
extends through the bearings 15, 18. The roll 28
revolves about shaft 33 and bearing 18. The 50
shaft 33 further functions as a means for con
necting the side portions 43, 44 of the carrier
together to prevent the spreading of such portions.
The carrier H has its sides 45, 46 of like form,
but oppositely disposed and said sides not only
include the outer portions 43, 44 but also inner
portions 19, 86 as well as intermediate portions
8|, 82 extending towards each other at anlin

portion 81 of section 85 is reduced and extends
51 and carries a sleeve-like adjustable nut ‘64
into and frictionally engages with the inner face
of the outer end of section 86. The latter in
proximity to section 85 is formed with a pair
which engages with the threads 63 and is em
site sides of the lower end of handle |8 by the
holdfast means 83. The lower ends of the lower
ployed for increasing and decreasing the tension
of member 51. The nut 64‘extends through the
of diametrically opposed openings 88, 89. The
opening 88 is of greater diameter than the open
ing 89. Encompassing and secured to the section
86 is an annulus 90 which is enlarged at one
side as at 9|. The annulus 99 is formed with a
pair of diametrically opposed openings 92, 93.
The opening 92 is of greater diameter than the
opening 93 but of less diameter than the opening
88. The opening 92 registers with the opening
The opening 93 is of the same diameter as
the opening 99 and registers therewith.
The manually. actuatable operating means I9
for the mechanism I6 is employed for revolving
the roll 29 which in turn will provide for the
15 revolving of the roll 29. The means I9 includes
an operating shaft 94 disposed lengthwise of the
section 86 of the handle I8. Within the section
86 is arranged an inverted cup-shaped upper
bearing 95 for and having an axial opening 96
20 through which passes shaft 94. Arranged with
in the section 89 is an inverted lower cup-shaped
bearing 91 for and having an axial opening
through which passes shaft 94. The latter ex
tends upwardly from bearing 95 and has ?xed to
transmit a revolving movement to the shaft 56
which in turn will revolve the gear 5|, provide
for the operation of gear 52 and the revolving
of roll 29 and which in turn will provide for the
revolving of the roll 29. The operation of the
rolls 28, 29 is had when the
to the shaft 56 the roll 29 may be operated in a
clockwise or an anticlockwise direction.
By pressing upwardly the roll 28 at a point in
proximity to carrier side portion 43 shaft 33 may
be disconnected from the carrier and carry roll
28 therewith for the purpose of removing or con
necting the mop from and to said roll.
Although the mop is shown as embodying a
pair of ties for the mop body, yet it is to be un
derstood that the number of ties may be in
creased as desired.
In operating the
25 its upper end a beveled pinion 99 meshing with
a beveled gear I00 ?xed to the reduced portion
of a shaft I02 disposed in transverse relation with
respect to section 86, mounted in one end in the
openings 89, 93 revolubly connected at such end
30 to annulus 90 and having its other end I03 re
duced and peripherally threaded. The gear I00
has a part thereof arranged in opening 98. The
hub of gear I00 is mounted in and extends out
wardly from opening 9!. The outer end of the
35 hub of gear I 00 is reduced. Positioned on the
reduced portion of the hub of gear I00 and bear
ing against the remaining portion of the hub is a
crank I04 provided with a handle means I05.
The crank I04 is clamped on the hub of the gear
I00 by a clamping nut I06 secured to the end
portion I03 of shaft I02. On the revolving of the
crank I04 shaft I02 will be carried therewith,
as well as the gear I00 whereby the latter meshing
tion is then applied to the mop and the latter
will be caused to assume the position shown in
Figure 2, that is, exteriorly of the bucket or pail.
What I claim is:
1. In a wringer-mop apparatus of that type in
cluding a carrier, a pair of lengthwise aligned 30
revoluble rolls within the carrier and a handle
secured to the carrier, the combination of a
pair of slides positioned at the sides of the car
rier, means for revolubly supporting one of said
rolls, means for revolubly supporting one end of 35
the other of said rolls from one of said slides, a
gear mechanism carried by the other of said
slides and connected to the other end of said
other roll for revolving it, a shaft connected to
said gear mechanism for driving it,
the said other shaft, and
with the pinion 99 will provide for the operation
of shaft 94. The bearing 91 is cut away as at I0'I
(Figure 6) to provide a clearance for the part 61
of the offset upper portion 66 of the rod 62.
The lower end of shaft 94 has ?xed thereto a
stop collar I08 which coacts with the lower bear
ing 9'! to arrest the upper shift of shaft 94. The
downward shift of shaft 94 is arrested by the
hub of pinion 99 engaging with the top of the
sion shaftuniversally connected at one end to
upper bearing 95.

sion shaft I09 formed of a pair of telescopic sec
tions H0, III and with the section I I0 slidably
arranged in and extended from the lower end
of section II I. The shaft I09 is disposed at an
revolubly supporting one end of the other of said
rolls from one end of said slides, a
to the inner end of the shaft 56. The section
III of the shaft I09 is universally connected at
its upper end with the lower end of the shaft 94
as indicated at H3. When the combined guid
ing and supporting element 20 is employed it is
mounted upon spaced portions of the top edge
