(both of 20th and Oxford Sta, Philadelphia, Pa.) Filed Apr. 18, 1962, Ser. No. 183,398 1 Claim. (Cl. 15-119) of an elliptically shaped ring having a slot or gap 13 opening through its bottom. The inner wall of the ring at both sides of the gap is provided with a groove 14 for the reception of a gap closure 15. One end of the gap closure is offset and pivoted at 16 to the extractor at one side of its gap. The upper face of the gap closure is shown as curved to form when the gap closure is in closed Mops are now on the market having a strand type mop position a continuation of the inner wall of the ring. The head with the extractor in the form of a split ring pivot 10 opening movement of the gap closure is limited by the ally supported on a longitudinally movable rod and with contact of its offset portion contacting an end wall of the cam means to move the extractor ‘downwardly over the groove 14. mop handle into aligned position wtih the mop head for In order that the .gap in the extractor may be narrow , the extracting movement of the extractor. the mop handle in rear of the mop head is in the form The mop handle must have sufficient strength for the 15 of a rectangular bar 17. A cam 18 mounted on the bar mopping operation and it has been found to be desirable 17 extends over the rear end of the rnop head, and the to reduce the size of the portion of the mop handle in rear wall of the cam has a cam face 19' extending down rear of the mop head ‘by forming such portion of a bar of wardly and ‘forwardly in the form of an inclined plane material. This enables one to reduce the width of the slot extending above and below the bar 17. The bar 17 is or gap in the extractor. If this slot or gap is wider than the mop handle, there is a possibility of strands of the mop head passing through the slot :or gap and becoming en tangled with the extractor. The object of this invention is to devise novel gap clos ing means which is automatically controlled. A further object of the invention is to devise a novel construction and arrangement of a cam which moves the connected with the mop head in any desired manner and the rear end of the bar is ?xed to- the main portion of the mop handle by a fastener 20‘. The guide 9 is cham bered to receive the 1bar and main portion of the mop handle, and the guide is aligned on the mop handle by a 25 rib 21 extending into the groove 3 in the mop handle. In the operation, the gap closure is automatically opened by contact with the bar 17, and is preferably auto gap closure into- its closed position prior to the extracting rnatically closed by the cam 13 as will now be explained. stroke of the extractor over the mop head, said cam also We will assume that the parts have been returned after moving the extractor towards the mop handle so that the 30 the extracting stroke of the extractor to the position gap closure is opened by contact with the mop handle. shown in FIGURES 1 and 2.

It is, however, to be under from the position seen in FIGURE 5 to that seen in FIG URE 6 ‘and the extractor will pass over the bar.
