Specification of Letters Patent.

Patented Apr. 21, 1914.

To all whom t may concern.'

Be it known that I, BENJAMIN WIL- LIAMs, a citizen of the United States, residing at Worcester, in the county of VVorcester and State of Massachusetts, have invented a new and useful Mop-Wringer, of which the followin is a specification.

This invention re ates to improvements in mop wringers.

The principal objects of the invention are to provide a simple and inexpensive mop wringer which can be applied to a pail or bucket in such a way that it shall be entirely unnecessary to touch any part of the same by the hands either to put it in condition for operation or to operate it. This is accomplished by means of a construction of parts so located and arranged that before the mop is put into the pail or bucket it can be caused to set the wringer in a very simple manner, and put the wringer in a condition ready to receive the mop, and by providing means lwhereby the raising of the mop through the wringer will operate certain parts to cause the wringer rollers to press against it on opposite sides, which in turn will operate connections to keep the mop in proper position.

Another object of the invention is to provide a construction in which a mop can be very easily inserted between the wringer rollers, after they are set apart by the operation of the mop itself as described above.

Further objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings in which- Figure 1 is a side view of a preferred form of the invention in position of receiving the mop; and Fig. 2 is a horizontal sectional view thereof on the line 2-2 of Fig. 1, showing a modification.

The invention as illustrated -comprises a supporting bar 10 adapted to be set upright within a pail or bucket 11, and having a plate 12 on the back thereof bent over so as to rest on the edge of the pail and receive a fastening screw 13 for clamping it thereto. On the other side of the bar 10 s fastened a spring 14 by means of the bolts 15by which the plate 12 is secured to the bar. This spring extends down toward the bottom of the bar and then outwardly and upwardly to a point near the top thereof. On it is a bearing plate 16 for a movable wringer roll 17 and opposite the latter is a similar bearing plate 18 on the bar 10 for a stationary wringer roll 19. Pivotally mounted on the top of the bar 10 is a latch 20 having a stop 21 and a notch 22. The latch is adapted to rest on the upper end of the spring and the notch to engage the end of the spring to hold the roll 17 back from the roll 19, `so that the mop can be inserted between them.

On the spring 14 is mounted a projecting arm 24 in position to be engaged by the mop before the latter is inserted in the pail. The downward pressure of the mop on the arm 24 draws it down and the `upper end of the spring 14 forward. This movement of the spring .causes the end thereof to engage under the notch so that the latch will drop and hold the parts in the position shown in Fig. 1. p The mo is then moved down at the side ofthe pai under water, and then is moved horizontally in between the rollers from one end `of the wringer. When the mop is centrally located it is drawn up, the too of the same engaging the latch 20 and lifting it, which releases the spring 14 so that the roll 17 is immediately forced by the spring against the mop. Now as the mop is drawn up the water is squeezed from it by the action of the roll 17 under the influence of the spring. The mop in its inward movement is limited by a stop 25 on a bar 26 pivoted on a bracket 27 on the bar 10 under the bearing plate 18. The end of the stop 25 comes up between the bearing plate 16 and its roller so that when the spring 14 moves in either direction the stop 25 moves with it and its opposite end 28 is moved in under the space between the ends .of the rollers when the movable roller moves toward the stationary roller. It can be seen therefore that in this position the ends 25 and 28 of the bar 26 serve as stops or guides for the mop and prevent it from moving beyond the ends of the rollers. If desired the spring 14 can be assisted by an additional spring 30 connected with the two bearing plates, as shown in Fig. 2.

It will be seen from the construction and operation described that the invention involves a wringer in which the entire operation is controlled by the mop itself, without necessitating any handling of the wringer or any particular attention on the part of the manipulator of the mop.

While I have illustrated and described a from the first roll, resilient means in the receptacle for holding the second roll toward the first roll, a latch above the receptacle for holding the rolls apart, and means whereby the downward motion of the mop near the movable roll will cause the latch to set the spring.

2. In a mop wringer, the combination of a wringer roll mounted in fixed position, a second roll movable toward and from the first roll, resilientmeans for moving thesecond roll toward the first roll, a latch for holding the rolls apart, and means adapted to be engaged by the mop for causing the latch to set the spring, said latch being located in such position that the upward motion of the mop between the rolls will disengage it and release the spring. v

3. In a mop wringer, the combination of a main support, a roll mounted thereon, a spring connected with said support, and extending downwardly and then upwardly at a distance from the support, a second roll mounted on said spring, said spring being adapted to normally force the second roll toward the irst'nained roll, a latch pivotally mountedl on the support and adapted to engage said spring to hold the rolls apart, and anarm projecting from the spring in position to be engaged by a mop in descending near the spring so as to pull the spring downward and permit the latch to drop by gravity and set the spring.

4. In a mop wringer, the combination of a support having means by which it is adapted to be secured in iixed position on the inside of a bucket or pail, a spring connected therewith and extending upwardly at a distance therefrom, two wringer rolls, one mounted on the spring and the other on the support, a gravity latch, and means whereby when the mop is being inserted into the bucket or pail the gravity latch will be permitted tofall into position to engage and hold the spring so as to keep the roll thereon away from the other roll.

5. In a mop wringer, the combination of a support, a spring connected therewith and extending upwardly at a distance therefrom, two wringer rolls one mounted on the spring and the other on the support, a gravity latch adapted to hold the spring back so as to keep the rolls apart and located in such position over the rolls that when the mop is drawn up between the rolls it will engage such latch and disengage it from the spi-ing so as to permit the spring to force the movable roll resiliently toward the stationary roll.

6. In a mop wringer, the combination of a support, means on one side thereof for securing it to the inside of a pail or bucket in fixed position, a spring secured to said support and extending downwardly therefrom, then away from the support and upwardly, a bearing plate mounted on the support, a bearing plate mounted opposite' thereto on the spring, two wringer rolls, one mounted to turn on each of said bearing plates, an arm projecting outwardly from the outer side of the spring at about the level of the rolls, and a gravity latch pivoted on the top of the support, resting at its outer end on the spring, and having a notch for engaging the vspring when the latch falls down, whereby the movement of the mop downwardly toward the pail or bucket will cause the mop to engage the arm and pull the spring out so that the latch will fall and hold the spring in such position that the roll thereon will be kept away from the roll on the support.

7. In a mop wringer, the combination of a support, means on one side thereof for securing it to the inside of a pail or bucket in fixed position, a spring secured to said support and extending away therefrom, and upwardly, a bearing plate mounted on the support, a bearing plate mounted opposite thereto on the spring, two wringer rolls, one mounted to turn on each of said bearing plates, and a second spring connected with said bearing plates for assisting the first named spring in moving one roll toward the other.

8. In a mop wringer, the combination of a support, a spring secured to said support and extending away from the support and upwardly, a bearing plate mounted on the support, a bearing plate mounted opposite thereto on the spring, two wringer rolls, one mounted to turn on each of said bearing plates, a bracket on said support under the bearing plate thereon, and a bar pivotally mounted on said bracket and having stops on the ends thereof projecting toward the movable roller, one of said stops projecting upwardly between the movable roller and its bearing plate.

9. In a mop wringer, the combination of a roller mounted in fixed bearings, a roller mounted in movable bearings, resilient means for normally moving the second roller toward the first, a pivoted bar having stops on the ends thereof projecting toward the movable roller, one of said stops having means whereby it is movable with the movable roller so that as the latter moves toward the stationary roller the bar will be caused to turn on its pivot and move the other stop into position below the space between the ends of the rollers.

10. As an article of manufacture, a, mop wringer having a roll in fixed bearings thereon, a movable roll, a spring for moving the movable roll toward the fixed roll, and a latch for holding the rolls apart, in position to be engaged by a mop when lifted,
