MOPS WITH EXTRACTING MECHANISM Filed April 18', 1962 United States Patent 3,089,171 MGPS WITH EXTRACTING MECHANISM Peter S. Voshikian, Melrose, Pa, and Thomas S. Vosbihian, Philadelphia, Pa. (both of 20th and Oxford Sta, Philadelphia, Pa.)

Filed Apr. 18, 1962, Ser. No. 183,398 1 Claim. (Cl. 15-119) Mops are now on the market having a strand type mop head with the extractor in the form of a split ring pivotally supported on a longitudinally movable rod and with cam means to move the extractor downwardly over the mop handle into aligned position wtih the mop head for the extracting movement of the extractor.

The mop handle must have sufficient strength for the mopping operation and it has been found to be desirable to reduce the size of the portion of the mop handle in rear of the mop head by forming such portion of a bar of material. This enables one to reduce the width of the slot 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 entangled with the extractor.

The object of this invention is to devise novel gap closing 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 gap closure intoits closed position prior to the extracting stroke of the extractor over the mop head, said cam also moving the extractor towards the mop handle so that the gap closure is opened by contact with the mop handle.

Other novel features of construction and advantage will hereinafter appear in the detailed description.

For the purpose of illustrating the invention, we have shown in the accompanying drawings a preferred embodiment of it which we have found in practice will give satisfactory and reliable results. It is, however, to be understood that the various instrumentalities of which the invention consists can be variously arranged and organized, and the invention is not limited, except by the scope of the appended claim, to the exact arrangement and organization of these instrumentalities as herein set forth.

FIGURE 1 is a top plan view of a mop having extractor mechanism embodying our invention.

FIGURE 2 is a section on line 2-4; of FIGURE 1.

FIGURE 3 is a sectional detail showing the cam closing the gap closure.

FIGURE 4 is a section on line 4-4 of FIGURE 5.

FIGURE 5 is a front elevation of the extractor partly broken away to show the gap closure in closed condition and the mop handle in position to cause the opening of the gap closure.

FIGURE '6 is a view similar to FIGURE 5 but showing the mop handle opening the gap closure.

Similar numerals of reference indicate corresponding parts.

Referring to the drawings.

A strand type mop head 1 is connected with a mop handle .2 having a longitudinal groove -3 into which a pin 4 extends, the pin being connected with an extractor handle 5 in the form of a grasping sleeve adapted to be reciprocated on the mop handle. Pivoted to the extractor handle at 6 is an actuating rod 7 which passes through a hole 8 in a guide 9 mounted on the mop handle. The front end of the rod is pivoted at 10 to spaced lugs or 3,989,1'?! Patented May 14, 1963 "ice arms 11 at the upper end of an extractor 12 in the form 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 position a continuation of the inner wall of the ring. The opening movement of the gap closure is limited by the contact of its offset portion contacting an end wall of the groove 14.

In order that the .gap in the extractor may be narrow the mop handle in rear of the mop head is in the form of a rectangular bar 17. A cam 18 mounted on the bar 17 extends over the rear end of the rnop head, and the rear wall of the cam has a cam face 19' extending downwardly and forwardly in the form of an inclined plane extending above and below the bar 17. The bar 17 is connected with the mop head in any desired manner and the rear end of the bar is fixed tothe main portion of the mop handle by a fastener 20. The guide 9 is chambered to receive the bar and main portion of the mop handle, and the guide is aligned on the mop handle by a 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 autornatically closed by the cam 13 as will now be explained.

We will assume that the parts have been returned after the extracting stroke of the extractor to the position shown in FIGURES 1 and 2. The operator moves the extractor sleeve 5 forwardly together with rod 7 and extractor 12. The lower end of the extractor contacts the cam face 19 to cause the extractor to swing downwardly and the bar 17 will cause the gap closure 15 to move from the position seen in FIGURE 5 to that seen in FIG- URE 6 and the extractor will pass over the bar. The extractor is passing over the cam 18 and the cam face 19 at its lower portion will press against the gap closure and positively move it downward into closed position. As the extractor proceeds over the cam, the bottom Wall of the cam maintains the gap closure in closed position. The extractor is now in aligned position with the mop head and moves forwardly over the strands to extract the water therefrom.

On the return or rearward stroke of the extractor after an extracting operation, the extractor swings upwardly in passing over the mop head, the rod 7 having a clearance in the hole 8 in the guide 9 to permit upward movement of the rod and extractor. The extractor passes rearwardly over the cam 18 and swings downwardly into contact with the bar 17 ready for the next extracting stroke.

The use of the gap closure prevents the mop strands from becoming entangled with the extractor, and also provides a more complete squeezing action.

The gap closure when released by the bar moves downwardly but due to dirt being present does not always close and we therefore prefer to have the cam ensure the closing.

Having thus described our invention, What we claim as new and desire to secure by Letters Patent is:

A mop, comprising a mop handle and a mop head connected to the forward end of said mop handle, the forward position of the mop handle in rear of the mop head being in the form of a rectangular bar, a slidable sleeve a) on the mop handle; a rod pivotally connected at one end to said sleeve, a guide on the mop handle through which said rod passes, an extractor in the form of a split ring pivotally connected at its upper end with said rod at a point forwardly of the sleeve connection, said ring having a slot at its bottom to permit it to pass over said bar, the inner wall of the ring at opposite sides of the slot being recessed, a gap closure pivoted to the ring at one side of the slot extending across the slot to seat in said recess and having its inner face curved to form when in closed position a continuation of the inner wall of said ring, and a cam on the handle in rear of the mop head being of sudh a shape that it causes said extracting ring during its forward extracting movement tomove downwardly and said bar causes the gap closure to move inwardly on its pivot and thereafter said cam because of its shape moves the gap closure into its closed position in its recess prior to its passage of the ring over the mop head during its forward extracting stroke.
