This invention relates'to mops.
...Figure 4 is’ an enlarged view of the jawyade. _
Among the objects of my invention are to. pro.
vide a mop which will provide a more effective
?at surface pressing downwardly .over a rela
.. tively large area againstthe mop cloth when in
use; to provide a mop wherein a sheet of. metal
. provides a relatively large, relatively'rig'id presser
plate for engaging the’ mop cloth over a rela
tively large area for pressing against the ?oor or
other surface to be'mopped and wherein the sheet
of metal is provided with an integral jaw member
cooperating with a relatively shiftable jaw mem
ber between which the mop cloth. isYclamped;
to provide a 'mop- head formed of an integral
piece of sheet metal'having a connection for the ’
mop stick socket and‘ wherein the sheet metal
is provided with struck-up sections which form a
mop jaw, hinge portions for connection to the
stick socket and guides for the cooperative mop
jaw and, in addition, provides a relatively large
presser plate over which the mop cloth extends,
and which presser plate serves to provide a rela
tively large surface for pressing the mop cloth
~ against the surface to be cleaned; to provide a
mophead which is formed with a single pivotal
connection between itself and the men stick and
which pivotal connection is also utilized as a‘
pivotal connection with‘the jaw clamping and

In general, my improved mop comprises a mop
head having a jaw, a cooperative jaw member
with means‘to produce relative movement be
tween' said jaw members for the insertion, clamp
ing and withdrawal of a cloth mop from the
head; a mop stick socket having ,a pivotal con

lastly while not necessarily, a wringer attach- ,
ment for cooperation‘ with the cloth or fabric
mop when in position on the mop head.
. In" order to provide a simple, economically
constructed and assembled mop», one having few
parts, of cheap manufacture and assembly, and
one having simplicity and e?iciency in‘ opera 20
tion, I prefer to'form the mop head of a single
piece of sheet metal 2 having an extended, pref
erably substantially, but not necessarily, square
shape.‘ This surface‘ is flat on. the bottom, as
shown in Figure 3. The front edge of the. flat 25
plate 2 is formed in any desired manner to pro- ‘
vide aijawlll. In the present instance the jaw is
formed by curling the front edge over, upwardly,
and-then inwardly in overhanging relation to the
upper. side of ‘the plate 2. At the ends the curved

wherein the shiftable ‘clamping jaw is pushed
upwardly in, a toggle-like action to clamping. po
sition, as distinguished from ‘being pulled into
clamping position; to provide these and other ob
jects of invention as will be apparent from a
perusal of the following speci?cation when taken
56 in connection with the accompanying drawing,
Figure 1 is a perspective view of a preferred
form of myimproved mop;
_ 1
Figure 2 is a side sectional view thereof;
55’ v Figure 3 is a section online 3—-3' of Figure 1;.
Speci?cally, I. prefer to‘ arrange the jaw so that
it is pushed into clamping engagement, and I
prefer to arrange and to form it of heavy gauged
wire ‘bent substantiallyin the form illustrated
in Figure 1.. This jaw is illustrated at Win the
drawing. vand is shown as provided with opposed
free ends» I2 and 1.4 which slide in holes. in up
standing ears l6 and I8 struck up from the metal
of the presser plate 2. An actuator in the form‘
ofa bar 20 is provided with a hole through which '
the vjaw 10. passes to provide an actuating con
Means is provided for pivotally attaching a
stick socket‘ 22 to the presser plate 2.
To accom
plish this, I preferably provide from the presser
plate two struck-up ears 24 and 26 formed in
tegrally from the metal of the plate.
These ‘ears '
are provided withv registering perforations to
which the furcations 28 and 30 of the stick socket
are pivotally riveted, as at 32 and 34.
The stick
socket is formed of sheet metal in any approved
fashion to receive and clampingly hold the end of
the mop stick, whereby the stick may shift from
a pivotal position lying somewhat in the plane of
the presser plate to a position at right-angles
In addition, I prefer to utilize the pivots 32 and
34 for pivotally mounting the jaw actuating lever
10 36. This lever is made out of a single piece of
sheet metal folded upon itself as at 38, and pro
vided with outstanding cars 40 and 42 .for en
gagement with the ?ngers. From the folded
portion 38 there extends rearwardly two spaced
15 apart arms 44 and 46 which spread outwardly and
rearwardly as at 48 and 50 and are pierced for
pivotal connection to the pins 32 and 34, re
the other end of which is bent in the form of an
oblong bow 10 through which the fabric mop 12 is
looped, as shown in Figure 2, the other end of
- the fabric mop being looped over the stationary
jaw 4 of the mop head and clampingly held there
in by means of the shiftable jaw H]. The mop
wringer handle and bow portion 10 are held in
desired position by means of a coiledrspring 14
which acts against the cross section of the bow
l0 and against the side of the stick socket 22. 10
Inasmuch as the shank portion 64 of this mop
wringer passes through the socket and the stick,
it holds them in assembled position. The spring
14 serves to hold the mop wringer handle 68 in out
of the way position. When it is desired to wring 15
the mop, the wringer handle is turned which
winds the mop spirally with relation to its
clamped position between the jaws whereby to
' spectively.
The portion 44 of this actuator is provided
with an opening for the reception of a cross-pin
52. This cross-pin is provided with an enlarged
wring out moisture and water from the mop.
Having thus described my invention, what I 20
end 54 and a spring 56 which bears against the
head of the cross-pin, normally urging the en
larged end 54 into position to engage a number
25 of spaced-apart enlarged holes 58 in the con
nector bar 20. A ‘narrower slot Gil joins each
one of the holes, and the width of this slot cor
responds with the diameter of a smaller shank
of the pin 52, so that when the head is pushed
30 inwardly the smaller shank will slide along the
holes into whichever one is selected, but when
the head of the shank is released or pushed out
