Improvements in or connected with Mop Wringers.
I, ARTHUR MCCAUSLAND BURNHAM of Gardiner in the County of Kennebec
and State of Maine in the United States of America Inventor do hereby declare
the nature of this invention and in what manner the same is to be performed to
be particularly described and ascertained in and by the following statement :-
My invention relates to improvements in mop wringers and has for its object to
produce a mop wringer having the mechanism located outside the main portion of
the pail.
A further object is to construct the device in such manner that the wringing
mechanism shall be located to one side of the main portion of the pail and at the
upper edge of said pail.
A further object is to produce a mop wringer which shall be simple and sub-
stantial in construction effective in operation and easy of manipulation.
With these objects in view the invention consists in certain novel features of
construction and combinations and arrangements of parts as hereinafter set forth
and pointed out in the claims.
In the accompanying drawings,
Figure 1 is a plan view of my invention.
Figure 2 is a sectional view on the line -x of Figure 1.
Figure 3 is a sectional view on the line y-y of Figure 1.
Figure 4 is a view in detail of a portion of the wringer.
A represents a pail having a spout or laterally projecting portion a or in other
words the pail is made in the form of a coalhod.
Rivetted to the bottom of the pail is a strip or plate b and secured to the bottom
of the pail, and having its securing bolt & passing through the strip or plate 6 is a
foot piece B. which projects outwardly from the pail and is provided on its top face
with serrations.
Located over the portion a is a frame C having arms c at one end, secured to
the pail by fastening devices c¹ said frame being secured to the portion a at or near
its other end by fastening devices c³.
The frame is provided with depending flanges d cut away on one side to produce
a passage e which communicates with the body of the pail as more fully explained
further on.
Projecting upwardly from the ends of the frame C to one side of the centre
thereof are uprights in the upper ends of which a roller D is journalled.
Journalled in suitable bearings in the flange d of the frame C at the opposite
side of the centre thereof from the roller D is a shaft E having a collar secured
to the centre thereof, by means of a set screw g¹.
g
A spring F is coiled about the shaft E and provided at its centre with a loop h
adapted to bear against the set screw g¹.
The free ends of the spring F are adapted to bear upon a bracket G having
arms h' h
The arms h project at an angle from the arms h¹ and at the angle formed by the
two arms perforations are made, through which a shaft E passes, whereby the
bracket G is mounted on said shaft.
At the upper ends of the arms 2 of the bracket G bearings i are made, for the
reception of the journals of a roller D₁ which by means of the spring F will be
maintained normally in proximity to the roller D and permitted by said spring to
yield when a mop is drawn through these rollers, the tension of said spring being
adjustable by means of the collar g.
Secured to one end of the shaft E is a toothed segment H, and mounted in its
Der

page_text: arms projecting from the frame C is a worm shaft I the worm of which is adapted
to mesh with the toothed segment H, said shaft being extended beyond its bearings
and provided with a crank or handle by which to operate it.
By means of this construction when it is desired to separate the rollers and
decrease the tension of the spring, it is simply necessary to turn the handle where-
upon the worm I will engage the segment H and cause the shaft E to turn and thus
permit said roller to move away from the roller D.
Projecting from the frame C in proximity to the inner bearing of the roller D
are two ears k in which a short shaft is mounted.
Fixed to said shaft is an arm or gate J having a handle J' by which to operate
it said arm or gate J being adapted to close the opening or passage in the
frame C.
In order to maintain the gate J normally closed a spring K is coiled about the
short shaft 1, being secured at one end thereto and at the other end to frame C.
Thus it will be seen that when the mop is placed in the pail, the handle of said
mop may be passed through the opening in the frame, the gate J yielding to
permit its passage and again closing automatically when the handle has passed
through the opening.
The mop can then be drawn through the rollers D D'.
Should it be desired for any reason to again move the mop into the body of the
pail, the handle may be moved through the opening in the frame by withdrawing
the gate J by means of the handle J.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The combination with a pail or receptacle, of a roller journalled in fixed
bearings, a roller journalled in a spring-actuated wringing bracket or frame and
means for regulating the spring pressure upon said roller bracket substantially as
set forth.
2. The combination with a pail or receptacle, of a pair of rollers, a shaft, means
for rocking the latter and holding it in position and a bracket or frame carrying
one of the rollers and mounted on the shaft, substantially as set forth.
3. The combination with a pail or receptacle, of a pair of rollers, a shaft, means
for rocking and securing said shaft, a bracket carrying one of the rollers loosely
mounted on the shaft, and a spring yieldingly connecting the shaft and bracket
substantially as set forth.
4. The combination with a pail or receptacle and a frame therein, of a pair of
rollers, one journalled in fixed bearings in the frame, a shaft having a spring coiled
thereon a toothed segment on the shaft, a worm adapted to operate to rock the
segment and shaft, and a swinging bracket loosely mounted on the shaft, connected
yieldingly therewith and having one of the rollers journalled in it substantially as
set forth.
5. The combination with a pail of a frame carried thereon having an opening in
one side and a normally closed yielding gate for closing said opening, substantially
as set forth.
6. The combination with a pail of a frame carried thereon having an opening in
one side, of ears on the frame in proximity to said opening, a shaft carried by said
ears, a spring encircling the shaft, and secured at one end thereto and at the other
end to the frame and a gate carried by said shaft adapted to close said opening in
the frame substantially as set forth.
7. A mop wringer constructed substantially as herein described.
