MOP AND WRINGER COMBINED Filed Nov. 26, 1928 ...h; 25 INVENTOR BY 7 E/ I a g 31.5 ATTORNEY Patented Nov. 12, 1929 UNITED STATES.

HARRY HERTZBERG, or BRoo K YNQNEw YORK MOP AND wnmenn comninnn Application filed November 26, 1928. Serial No. 321,925.

This invention relates to mops for household use and the like and particularlyto that type of such mops which have a device for wringing the mop cloth or cords attached to the mop structure.

It is the object of this invention to provide a device of this kind which consists of very few parts and yet is of rigid construction and extremely simple in operation.

It is a further object of the invention to provide a wringing device which is always ready to be operated without the necessity to place either mop or wringer in acertain position.

WVith these and other objects in view which will become clearer as the appended description progresses, the invention resides in a novel combination of parts and details of construction shown on the accompanying drawings which form a material part of this disclaims.

In the drawings:

Fig. 1 is a perspective view of my mop with wringer.

Fig. 2 is a detail cross section of the wringer of Fig. 1 showing the toothed rollers in engagement with the mop material.

Fig. 8 is a detail showing the mounting of the lower roller and means for removing the same and the mop material from the supporting frame.

The frame 10 comprises a fiat bar bent upon itself at the center to form projection 11, and bent at its ends to form a yoke having roller supporting brackets 12 and 12 The projection 11 is inserted into an axial slot at the lower end of mop stick 13, collar 14 encloses the slotted portion of the mop stick, serving to reinforce the same, and pins 15 hold these parts in place.

In journal apertures of brackets 12 and 12 and in operative relation, are rotatably mounted on shafts 19 and 21 toothed rollers 16 and 17 loosely meshing with each other, of these rollers 16 is fastened to its shaft to be rotated thereby, while 17 is loosely mounted on its shaft 21. Between these rollers, mop material 18 is held incompressed condition.

The mop material 18 consists preferably of so a continuous cord coiled in loops of equal closure and are finally pointed out in the size lying alongside of each other and stitched together toform an endless mop cloth.

' On the shaft 19 of roller 16 is fitted a knob 20, preferably keyed thereto, whereby :roller 16 may be rotated. -Ro1ler 17 meshing with roller 16'is caused to rotate thereby so that the various parts of mop 18 may be wrung. The

ends of shaft 21 which holds'roller 17 journalledin brackets12 and 12 are covered by resilient caps 22 which prevent longitudinal motion of the shaft. These caps may be bent outward into the dotted position of Fig. 3 and rotated 'about screw 23-to release shaft 21 for itsremoval and to release roller 17 for exchange of the mop cloth. After 'thisfexchange and replacement of roller 17 and shaft 21the'caps are placed in their original posi tion and by their resiliency lie against the vertical side of the supporting bracket.

It will appear clearly from the above description that this mo and wringer combination is a compact an efficient structure, and that the assembly of its severalparts is very simple, particularly as the rollers which sup port the mop material are also the means for wringing it and furthermore serve to hold this material stretched to lie fiat on a floor to be mopped. The wringing operation may be started at any desired moment as the endless mop material is always in'the same position relative to the rollers.

However, while the preferred form of the device has been described hereinabove, as an example of the many ways of constructingit,it is understood that such changes may be made in the arrangement of parts and the construction of minor details thereof, as come within the scope of the invention as claimed, with out departure from the spirit of the invention.

What I claim as new and desire to secure by 7 Letters Patent is:

1. In a device of the character described, a yoke formed to provide means for attachment to a mop handle, a pair of parallel lugs at opposite ends of said yoke, a pair of toothed rollers operatively mounted on shafts held in fixed position within bearing apertures in said yoke, a handle on the shaft of one of said rollers for rotating the same, the second roller being loosely mounted on its shaft adapting said shaft to be removed from said yoke through one of the bearing apertures.

2. The combination with a mop stick of a wringer comprising a yoke, toothed rollers rotatably mounted within said yoke on shafts laterally fixed within bearing apertures of said yoke,mopmateria1 supported in thespace between said. rollers to be propelled and wrung thereby, fastening means formed integral with said yoke for holding it rigidly connected to said mop stick, one of said rollers being adapted for disengagement from its shaft and said shaft being removable from said yoke in axial direction to permit release of. said mop material.

' 3. The combination with a mop stick of a yoke having a plate integral therewith adapted to enter a longitudinal slot in said mop-stick and fastening means passing transversely through said plate and mop stick, a pair of rollers mounted on shafts fixed Within apertures in said yoke, mop material forming an endless looped sheet supported between said rollers to be propelled and wrungv thereby continuously one of said rollers being detachable from its shaft and said shaft being detachable from said yoke and meansfor holding said shaft longitudinally fixed within said yoke.

Signed at Brooklyn, in the-county of Kings and State of New York, this 17th day of November, A. D. 1928'.
