SFEQIFIUATIUW forming part of Letters Patent No. 668,102, dated February 12, 1901.

Application filed May 4, 1900. derial No. 15,502. (No model.)

To will whom it may concern:

Be it known that 1, JOHN H. JOHNSON, a citizen of the United vStates, residing at Silverton, in the county of Marion and State of Oregon, have invented a new and useful Mop- "Wringer, of which the following is a specification.

lily invention relates to mop-wringers, and has for its object to produce a device of this kind which can be cheaply constructed, will be simple and eiiicient in operation and can be readily moved from place to place, so as to be convenient for use when needed.

vVith this object in view my invention consists in the improved construction and novel arrangement of parts of a mop-wringer, as will be hereinafter more fully set forth.

In the accompanying drawings, in which the same referencenumerals indicate corresponding parts in each of the views in which they occur, Figure 1 is a perspective view of my mop-wringer ready for use. Fig. 2 is a vertical central sectional view of the same. Figs. 3 and i are sectional detail views at right angles to each other, taken through the free end of the pivoted jaw.

Referring more particularly to the drawings, 1 indicates the base, which may be of anysuitable size and dimensions, upon which are mounted suitable standards 2, preferably three in number. A table 3 is secured to the upper ends of the standards and is provided with an upwardly-projecting rim 4, which terminates in a spout 5. The table is prefer ably substantially circular, and the spout overhangs orprojects beyond one side of the base, so as to deliver the water from the mop into the bucket when the wringer is being used.

Journaled within suitable bearings 6 and '7 in the base and the table, respectively, is a vertical shaft 8. The shaft is provided with one or more spiral grooves 9, which extend from directly below the table to its lower end, and a head or nut 10 is arranged to travel upon the shaft, its interior being provided with a projection or rib 11 for each one of the spiral grooves. A substantially L-shaped stirrup 12 is secured to the nut 10 at one end and engages with one of the standards at the other endas, for instance, by means of a perforation 13. A coiled spring lelfits around the shaft Sand extends from the base up to the nut, so as to normally hold the nut and stirrup at their highest point. If desired, the lower end of the spring may rest within a suitable annular recess 15 around the hearing at the bot tom of the shaft. The upper end of the shaft directly below the table is provided with a collar 16, which engages with the bottom of the table and prevents the spring from lifting the shaft out of its hearing at the bottom and also limits the upward movement of the nut 10 against the action of the spring.

Secured to the upper end of the shaft above the table is a head comprising a base or crosspiece 17, two standards 18, and two

jaws

19 and 19, one of which, 19,'is secured to the tops of the standards 18 and the other one, 19, is pivotally secured to the jaw 19 at one end, the pivoted end of the jaw 19 being curved sufficiently to cause the jaws to stand substantially parallel to each other when in their closed position, and thereby hold the mop firmly between the two jaws. The opposite ends of said jaws are detachably secured together by means of a curved rack 20, one end of which is secured to the jaw upon the tops of the standards, and the other end extends beneath the pivoted jaw and is provided with teeth 21, preferably upon its upper surface, with which a pawl 22 engages. The pawl is pivotally seated in a recess 23 in the upper suface of the pivoted jaw, and a spring 24 engages with its inner end for holding it in normal engagement with the teeth of the rack 20. The teeth of the rack are inclined away from the rigid jaw upon one side, and the head or engaging end of the pawl is also inclined away from the rigid jaw, so that when the movable jaw is being moved toward the rigid jaw the pawl will slide over the inclined surface of the teeth; but its straight face will engage with the straight faces of the teeth of the rack and prevent the outward movement of the free end of thejaw until after the pawlhas been released by pressing downwardly upon its outer end. A bracket 25 is secured to the under side of the pivoted jaw and extends underneath the track, so as to prevent the accidental disengagement of the jaw from the rack. The inner or adjacent faces of the jaws are each provided with suitable means for engaging with the mopas, for instance, teeth or pointed pins 26.

In using 'my improved mop-wringer it is placed adjacent to the bucket or other receptacle for the water used, in scrubbing,

with the spout of the table projecting over the edge of said receptacle. The jaws are separated by releasing the pawl from the rack and forcing the free end of the pivoted jaw away from the rigid jawa sufficient distance to permit, of the entrance between the jaws of the mop that is to be wrung or dried. The pivoted jaw is then swung inwardly toward the rigid jaw as far as it will go, the teeth or pins upon the coacting faces of the jaws rigidly clamping and holding the material of the mop therebetween. The operator then places the foot in the stirrup and forces the head downward as far as desired, which will cause the head to be revolved above the table, and

by holding the handle of the mop rigid between the hands of the operator the fibrous material or scrubbing portion of the mop will be twisted around and around until it has been sufficiently dried or cleansed from water. As soon as the foot is released from the stirrup the spring upon the shaft will carry the head or nut upward, which will cause the shaftto revolve in the opposite direction, and thereby untwist th'e fibrous material of the mop. The pawl is then released from the rack andthe pivoted jaw moved away from the rigid jaw, when the mop can be removed from the wringer for further use. By form ing the spiral grooves upon the shaft to the right hand or in the same manner as the threads of an ordinary screw and locating the free end of the pivoted jaw to the right,where it will be the most convenient for manipulation by the right hand, the head and the shaft will be locked against rotation when the mop is being clamped within the wringer, owing to the engagement of the nut lO'with the collar16,thus permitting of the pivoted jaw being drawn toward the rigid. jaw with sufficient force to clamp the mop so tightly as to prevent its slipping from between the jaws during the process ofwringing.

As above described, it will be evident that the process of ringing the mop can be performed quickly and efficiently and without soiling the hands.

The device is so simple that any one can operate it, and it can be made of such strength that it will not be easily broken and yet be made light enough to be easily carried from place to place when desired.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
