Patented Jan. 6, 1931 rarer orrics WALTER s. FINNEL'L, OFI-IANNIBAL, MISSOURI, Assrenoa 'ro FINNELL SYSTEM, 1110., or rrAnnIBAL, MISSOURI, A CORPORATION or DELAWARE MOP WRINGER Application filed Jul 1,

My invention relates generally to mop wringers embodying a movable wringer roller and. has to do particularly with novel handle structure for moving such roller to and from wringing posit-ion.

. This invention particularly adaptable to a wringerstnicture such as disclosed'in to permit ready movement of such short handie to its open and closed positions. Also, in

such construction in the event ofa foreign object striking the roll during wringing operation, there is danger of this roller handle accidentally releasing and injuring the operator. I

The principal object of my invention is to provide a roller operating handle which may 'be of any desired length to givethe desired leverage and wringer power, andwhich is so arranged'as to not interfere with operation when the rollers are in wringing position. The arrangement is also such that the handle will not strike the operator in the event that the rollers are accidentally released.

A further object is to provide a collapsible form of handle for accomplishing the foregoing and which automatically assumes its collapsed position when released by the op erator.

Other objects and advantages will become apparent as this description progresses and by reference to the drawings Wherein,

Figure 1 is a tpp plan view of a wringer structure embodying my invention. and showing the roller shifting handle in collapsed position in full lines and in extended position in dotted lines.

posit-ion and the operating handle extended.

F 1g. 3 is an enlarged perspective view of a portion of the handle and its support.

Referring to the drawing the wringer frame 10, which includes the side angle bar member 10, is carried upon a support which may take the form of a receptacle 11. The 1 10" of the side members are curved downwardly intermediate their ends and serve to position the frame upon its support asis obvious in Fig. 2. These side members carry the stationary wringer roller 12 and the shiftable roller 13 wiiich is moved back and forth and positioned by means of the springs 14. and the rocker shaft 15 in a well-known manner.

The rock shaft 15 is moved to and from its opened or closed position by a handle 16 which is of such length as to provioe the necessary leverage to effect the above move ment with ease and speed regardless of the so-called power of the wringer or the opposing pressure of the springs 14. This handle is collapsibly carried by the shaft so that when not in use it will fall away from the operator and wringer rollers so as to not in terfere with the wringing operation and may not be moved to in urethe operator in case the rollers are accidentl y opened. This collapsible mounting comprises aboss 17 carriedon and in a right-angular relation to a lateral extension 18 on the rock shaft. This boss is provided. with pocket 19 open at one side which is adapted to receive one end of the handle 16. While the cavity 19 is shown open at its left side in the drawing, it will 'be'understood that this opening may be at either the right or the left side, depending "upon the choice of theuser. I A bolt 20 passes through suitable openings in the handle-and boss for hinging these parts together. As shown in the drawing. this construction permits of folding of the handle to the left upon the wringer frame (Fig. 1). I

It is desirable from the standpoint of safety and efficiency in the operation of the wringer that the handle automatically assume its. collapsed position upon movement of'the wringerroll13 to its closed position and the release of the same by the operator.

Toaccomplish this I, preferably, incline the .boss 17 to the left, or in thevdirection of the open sideof the pocket 19, to such an extent that the handle is tilted 'sufficientlyin its u right or extended and rollerclosing position to cause it to fold over about the hinge bolt 20 when released. Or, if desired, the inner --wall of the' boss pocket 19 may be inclined to the left so as to hold the handle in the desired tilted position. The open side of the pocket throughwhich the handle oper-' ates is located at such a position that the handle will readily clear the operating parts as it folds over." in

In use, when it 1s desiredflto "open the 'wringer rolls, the handle is moved to an upright or extended position and then moved toward the operator to the position of Fig- 2..

The-operator may thenmove the handle to one side 'to permit" of ready access to' the wringer'rolls. When the wringer' rolls are to be closed, the handle is moved to an extended position,if it is not already in that position, and moved away from the operator to its closed position. In this position, the handle stands upright and when the operator releases the same it will automatically move to the position shown in Fig. 1. The

operator may then proceed with .the wringing operation by turning the handle 21 Without danger of being injured by accidental movement of the handle 16. Furthermore,

the long handle 16 and the increased lever-o age,enables the operator to readily move the rock shaft 15 backward and forward regardless of the power in the springs 14.

While I have shown'only one form of em 'bodiment of my'invention, it will be understood that various changes and modifications may be resorted to without departing from the scope and sp rit of my inventionas dejfinedjby' the appended claims.

lclaimr V 1. In a mop wringer having a wringer roller, a rocker having its axis substantially parallel with the axis of said roller for shifting said roller back an'dforth, a handle. for said rocker, and a hinge between said handle and rocker at substantially right angles to the latter which intone position of the parts fixes said handle and rocker together against relative rotary rocking movement in one direction and provides for folding of said handle longitudinally of said rocker and substantially parallel with the axis of said roller. 2. In amop wringer having a shiftable roller, a rocker operatively connected to said rollerfor moving the same back and forth, a handle, and a'connection between said handle and rocker comprising a'hollow, opensided extension on said rocker at an angle to the longitudinal axis thereof, saidextension being adapted to receive one end of said handle," and means for hinging said handle an upright to a folded position laterally of the wringer and vice versa.

3. In a mop wringer, the combination with a roller and a rocker for shifting said roller back and forth, of a handle on said rocker foldable laterally with respect to the wringer, and connections for efiecting' said folding movement including an inclined element movable with said. rocker.

4. Ina mop wringer, thecombination with a roller and a rock-shaft, for shifting said roller back andforth, of a handle for said .rockerand connections between said handle and'rock shaft including a hinge element carried by and inclined toward the rock shaft rendering said handle self-'fold'a-ble into a substantiallyparallel relation to said shaft.

5. In amop Wringer, the combination with aroller and a rocker for shifting saidroller back and forth, of a handle for actuating said rocker,and a tilted hinge carried by said rocker and connected tosaid handle for folding the handle transversely of the wringer and into a substantially parallel relation with said roller. v V v 6. In a mop wringer, the combination with of the same through said open side only from a roller and a rockerfor shifting said roller back and forth, of a handleifor said rocker,

and connecting means between'said handle and rocker for folding the handle uponthe wr nger comprising a socket membercarried by said rocker and adapted to receive one end of said handle and having a slot in its wall through which the handle passes, said socket member being carriedinatiltedrelation to the axis of said rocker.

7'. In a mop wringer having a. shiftable :rolle'r, a rock shaft for shifting said roller back and forth, yieldable connector elements between said shaft and roller, a handle for said rocker, and means carried by said rock shaft for connecting said'handle and rock shaft in such a. manner as topermit folding of the former laterally of the wringer, said means including an inclined socket member mounted on said rocker and adapted to pivotally receive one end of said handle.

In testimony whereof, I have subscribed my name.
