Application June 29, 1940, Serial No. 343,295
The invention relates to improvements in mop wringers of the general type shown in my U. S. Patent No. 2,166,965 of July 25, 1939, the principal object of the present invention being to provide a generally improved construction which may be more advantageously manufactured and will pro duce better results.
In carrying out the above end, further objects are to provide simplified means for moving the side walls of the mop squeezing receptacle inwardly when said receptacle is depressed; to provide for adjustment of the receptacle side wall movement according to the size of the mop to be wrung; to provide the receptacle with an improved bottom structure which aids materially in wringing the mop; to provide an improved form of carriage for the vertical arms which carry the mop wringing receptacle and are connected with the side walls thereof; to provide novel yieldable connections between the aforesaid arms and a vertically slidable carriage with which they are connected; to provide a tie bar for the carriage-guiding tracks acting also as a stop for upward movement of the carriage; to make novel provision for connecting the wringer to a bucket, and to provide a novel construction which facilitates carrying both the wringer and the connected bucket with one hand.
With the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, description being accomplished by reference to the accompanying drawings.
Fig. 1 is a perspective view showing the wringer.
Fig. 2 is a central vertical sectional View showing the wringer connected with a bucket.
Fig. 3 is a detail sectional View showing the manner in which the pivoted bottom section of thereceptacle may be swung upwardly to provide an opening through which the fingers of one hand may be inserted when carrying the wringer and bucket.
Fig. 4 is a detail perspective view showing the metal blank from which the arm-carrying carriage is formed. v
A preferred construction has been illustrated and will be rather specifically described, with the understanding, however, that within the scope of the invention as claimed, variations may be made.
The frame structure of the wringer includes a horizontal rectangular top frame 5 to rest upon the rim of a bucket B, one end of said frame being provided with a longitudinally curved bar I to book under the usual bead 8 at the bucket rim.
the bucket and disconnectable therefrom. The
bar I is adjustable according to the size of the bucket to be used, and in the present disclosure, the ends of this bar are turned upwardly at Ill and adjustably connected with the side bars of the frame 5 by bolt and slot connections IL.
The frame structure of the wringer also includes a substantially U-shaped frame 12 having the upper portions l3 of its side armsofiset outwardly from the lower portions M of said arms, and suitably secured at [5 to the side bars of the frame 5, the two frames being relatively braced by suitable braces IS. The arm portions l4 constitute parallel vertical tracks upon which a carriage I1 is slidable. This carriage, in the present showing, is formed from the metal blank shown at l8 in Fig. 4, this blank or plate being horizontally elongated and having openings l9 in its ends through which the tracks Hi pass. On lines spaced inwardly from its ends, the plate I8 is transversely slit inwardly from its edges as denoted at 20, permitting the major portions of the longitudinal edges of said plate to be bent upwardly, providing vertical flanges 2i. Pairs of vertical arms 22 and 22 have their lower ends disposed at opposite sides of the flanges 2|, and bolts 23 pass through said ends of said arms and through said flanges. Washers 24 of rubber or other elastic material are mounted on the bolts 23 between the arms and the flanges and prevent rattling of the connections between said arms and. the carriage l1, said Washers yielding somewhat as the arms 22 and the arms 22 swing inwardly or outwardly. When the device is to be adjusted for large mops, more Washers 24 may be added, and for small mops, some of the washers may be taken out.
The mop-wringing receptacle 25 includes two side walls 26 and 26 which are preferably perforated, wall 26 being secured to the upper ends of the arms 22 and wall 2'5 being secured to the arms 22 The receptacle also preferably includes overlapping wings 21 and 2'! on the ends of the walls 26 and 26 respectively. The lower edge of wall 26 is provided with a fixed bottom section 28 for the receptacle 25, and the wall 26 carries an upwardly swingable bottom section 28, this section being hinged at 29 so that it may swing vertically. The bottom section 28 is so inclined that when the receptacle 25 is contracted (walls 26 and 26* move toward each other as in connected with the Wall 26.
dotted lines in Fig. '2), it will upwardly swing the section 28 with respect to the side walls 26 and 26*, thus upwardly squeezing the mop for better wringing while said walls are inwardly squeezing the same. Obviously 28'= simply slides upon 28 as the receptacle is contracted. The pivotal mounting of the section 28 also permits this section to be upwardly swung against the wall 26*- as shown in Fig. 3, providing an opening through whichthe fingers of one hand may be downwardly inserted to hook them under the wall 26 for carrying the wringer and the connected bucket.
Two links 30 are directly pivoted at their upper ends to the side wall 26, said links being preferably rigid with the ends of a rock shaft 31 mounted in bearings 32 carried by said wall. The
lower ends of these links are directly pivoted at 33 to the side bars of the frame 5, said side bars preferably having upstanding lugs 34 with which the pivots 33 are engaged. The pivoted lower ends of the links 353 are provided with downwardly projecting arms 35 to which coiled, tension springs 36 are connected, said springs being anchored at 31 to the upper ends of the side arms of the frame l2.
Two additional inclined links 3i] are associated with the side wall 26 their upper ends being pivotally connected with said wall at 3W, preferably in the same manner as the links 30 are At the lower ends of these links 3!)", the side bars of the frame 5 are provided with brackets 31 having curved portions 38 formed with openings 33 through which said lower ends of the links pass loosely. Coiled compression springs 40 surround these links and at their lower ends abut the convex surfaces of the curved bracket portions 38. The upper ends of these springs abut nuts or other suitable stops 4! adjustable along the upper portions of the links 30*. The lower ends of these links are provided with other stops ll.v adjustable along said links and abutting the lower sides of the bracket portions 38. The stops .42 may well be in the form of cotter pins or the like insertable through any of a plurality of openings 43 in the links 38*. It will be seen that by adjusting the stops 4! and 42 longitudinally of the links 33 the receptacle side wall 26 may be adjusted toward or from the wall 26, changing the effective size of the receptacle according to the size of the mop with which the wringer is to be used.
At 43 I have shown an upward extension on the receptacle wall 23 which aids in guiding the mop into the receptacle, and at M an inclined plate has been illustrated to guide the mop into the bucket 6 when it is to be immersed in the wash water. The upper end of plate 44 is suitablysecured to an arched bar 45 extending transversely of and secured to one end of the frame 5. When the latch 9 is of the construction shown (one piece'of spring metal), bar 45 may also aid in connecting this latch with the frame.
Due to the pull of the springs 35, the parts normally stand as shown in Fig. 1 and in full lines in Fig. 2, the upward movementof the carriage I! being then limited by a tie bards which extends between and .is secured to the upper portions of the tracks It. When a mop head is inserted in the receptacle 2-5 and the mop handle pushed downwardly, the receptacle, the arms 22 and 22 and thecarriage Hall move downwardly. During this downward movement, thelinksflfl and 30are caused; to swing inwardly and downwardly as shown in dotted lines in Fig. 2 thus forcing the receptacle side walls 26 and 26* inwardly toward each other to press and squeeze the mop. During the inward movement of these side walls, the bottom section 28 slides inwardly and upwardly upon the fixed section 28, further squeezing the mop at the lower end. When the device and connected bucket are to be carried from one point to another, it is an easy matter to upwardly swing the bottom section 28 as shown in Fig. 3, permitting easy use of one hand to grasp the lower end of the side wall 26*. When adjustments are required for larger or smaller mops, this may be readily accomplished by adjusting the stops H and 42 associated with the links 30%, and by adding or subtracting washers 24 associated with the carriage I7. Moreover, these washers 24 prevent loose rattling of parts and will of course yield as the arms 22 and 22 swing inwardly and outwardly.
On account of the excellent results. obtainable from the details disclosed, they are preferably followed. However, within the scope of the invention as claimed, variations may be made. For example, instead of using the elastic washers 24, coil springs or other suitable springs could be used, being mere mechanical equivalents. It will also be understood that the arms 22 and 22 may be made from spring steel if desired to yield when a large mop is being wrung.
