This invention relates to improvement in mop wringing appliances and provides a device of this character embodying a simple but eiective l mechanical arrangement to be used in connection Y5' with water pails.
v ing drawing, and more specifically pointed out in the sub-joined claims.
With reference to the drawing: Figure 1 is a side elevation of the complete invention and showing the same normally attached to the customary water pail; the latter being illustrated in phantom.
Figure 2 is a sectional view of the invention taken substantially upon line 2-2 of forth-coming Figure 3, with the pail also in section and the device illustrated as of the act of being actuated.
Figure 3 is a top plan view of the invention with the pail shown by dotted lines.
Figure 4 is a top plan view of the base plate of -the clamping unit.
Figure 5 is a top plan View of a part of the clamping unit.
Figure 6 is a top plan view of the base plate of y the foot lever mechanism.
Figure 7 is a vertical sectional view of the pivotal portion of the top part of the mechanism.
The invention comprises substantially a frame having parallel sides 1 and radial front 2 as indicated. The rear end of said frame having a ra- `dial member 3 that is adapted to be pivotally secured to sides 1 by rivets 4. Member 3 is provided with notched portions 5 so as to detachably engage rim A of pail B, for a purpose which Awill be presently explained.
The method for clamping the front part of the mechanism to pail B consists of L member 6 having U portion 7 formed thereon, and this portion being adapted to engage radial front 2 where K shown and permanently secured thereto in any approved manner. Said member also having right angular portion 8 formed thereon which is provided with U slot 9, and said slot being for the purpose of accommodating the detachable en- ...gagement of externally threaded end 10 of ver- V'tically disposed rod 11, also nut 10A being ar- I(CL 15-262) ranged to engage end 10 for the intended purpose. The opposite end of said rod being adapted to permanently engage sleeve portion 12 of base plate 13. Referring more particularly to Figure 4 it is observed that radial upturned clips 14 are formed upon plate 13 where indicated and are adapted to engage flange C of pail B as in Figure 1.
The method for clamping the rear part of the mechanism consists of radial member 3 which is pivotally secured to sides 1 of aforesaid frame by virtue of rivets 4 as previously explained and due to the oscillatory motion of member 3 and notches 5 therein the frame is placed over rim A of pail B with said notches engaging said rim in the manner as indicated.
Rollers 15 and 16 are provided with the usual axial pins 17 as shown. Roller 16 being rotatablyl and permanently engaged with sides 1 of the frame, and roller 15 being rotatably engaged with yoke member 18, which is formed of two pieces as clearly shown in Figures 1, 2 and 3. Member 1,8 has projecting ends 19 that are connected by rivet 20 in a manner so as to provide space between said ends for the passage of end 21 of lever 22 and the detachable engagement of said end with rivet 23 which is secured to the ends. Slot 24 in said end being provided for this purpose.
Additional base plate 25 is provided and has upturned radial clips 26 where shown, said clips be- 85 ing adapted to engage flange C of pail B. Permanently secured to said plate is vertically arranged U portion 27, and the lower end of lever 22 being pivotally secured to said portion where shown by rivet 28.
Link 29 is employed and the upper end thereof is pivotally secured to lever 22 where shown by rivet 30. The lower end of link 29 being likewise pivotally secured to foot lever 31 by rivet 32, and 1-,
one end of said lever pivotally secured to U memv ber 2'7 by rivet 33. Also coil spring 34 is employed, one end of which is connected to member 3 and the opposite end thereof to link 29.
The details of construction of the invention having been completely set forth in the foregoing, the operation and advantages thereof followzI Base plate 13 with rod 11 connected thereto is placed to pail B with clips 14 of said plates engaging flange C of said pail, and by reason of U member 6 being secured to front 2 of the frame, the 105 upper end 10 of said rod is placed within slot 9 and by means of nut 10A being drawn upon portion 8 of said member, the front part of the mechanism is securely clamped to the pail. The frame now being upon rim A of the pail and due to the osoillatory motion of memberB and notches 5 within same, the member is pressed downward engaging said notches with rim A of the pail, thereby clamping the rear part of the frame to the top part of the pail.
Base plate 25, with U portion 27 thereon and also levers 22 and 31 pivotally connected to said portion, is placed to pail B with clips 26 engaging ange C of said pail. Upper end 23 of lever 22 is then connected to yoke member 18 as shown in Figure 2. One end of spring 34 being permanently connected to member 3, the opposite end of said spring is then connected to link 29 where shown, and the device is now ready for normal' operation as indicated in Figure 1.
With all previous explanation in mind, it is noW understood that one foot of the operator is placed over base plate 13 and by means ofv the remaining foot of the operator, lever 31 is depressed by this foot, and through the various elements named, and by virtue of elongated slot 35 within parallel members 1 respectively, roller 15 is moved toward roller 16 as indicated in Figure 2, with the mop disposed between said rollers in the usual manner. The mop is then drawn through the rollers in-this position thereby thoroughly wringing the same in an eiective manner.
The principal advantages derived are that the pail is positively retained upon the floor during operation; ease in operation with powerful lever- "age and with little energy required; minimum number of parts preventing complicated disorders, and lastly due to the simplicity of the device same may be manufactured at a low cost and marketed at a price within the reach of all.
Having thus described my invention, what I claim as new is:
1. In a'mop wringing device, a yoke member for same, a mechanism for actuating said yoke member comprising a vertically disposed lever, means 'for detachably securing one end of said lever with said yoke member, a base plate, a vertically eX- tending U member permanently secured to said plate,the opposite end of said lever being pivotally secured to said U member, a foot lever and a link, said foot lever pivotally secured to said U member, and said link disposed intermediate firstnamed lever and the foot lever and being pivotally connected to both elements, and spring means relative to the frame and the aforesaid link.
2. In a mop wringing device, a frame for same, a front clamping unit for said frame, said unit comprising a base plate, a sleeve portion and radial clips formed thereon, a vertically arranged rod, the lower end of said rod permanently connected to said sleeve portion, a U member, said member secured to the front portion of aforesaid frame, said U member having an open slot therein, the upper end of said rod to detachably engage said slot and the rod retained within said U' member'by a nut engaging the upper end of said rod,- the aforesaid clips being adapted to engage the lower flange of the water pail.
3; In'amop wringing device, a principal frame having. parallel sides and a'radial front adapted to detachably engage a water pail, a roller rotatably and permanently secured to said sides, each of said sides having an elongated slot therein, an additional roller rotatably disposed within said slots, a yoke member and a vertically arranged lever, means for detachably and pivotally securing the upper end of said lever with said yoke member, a base plate, means upon said plate for clinching the lower flange of the pail and further Imeans upon said plate for pivotally supporting the lower end of said lever, manually operated means whereby said lever may actuate aforesaid yoke member in a` manner so as tomove the lastnamed roller toward the rst-named roller in the normal operation of the device, a front' clamping unit, said unit having a vertically arranged rod, means for detachably securing the upper end of said rod to the front of aforesaid frame, a base plate for said unit, means for clinching same to the flange of the water pail, and further means for permanently supporting'the lower end of said rod.
