Application July .26, 1934, Serial No. 736,987

4 Claims.

This invention relates generally. to mop heads and more particularly to an improved form of meansforpivotallyconnecting a mop head to a handle therefor.

It is the object of this inventionto provide a holder for a mop head which consists of a single piece of metal adapted for attachment to a mop handle at itsprear portion and provided at its front end with a tubular part for securely and adjustably holding the pivot bar of a mop head.

It is another object of this invention toprovide separate means on the tubular part of the mop holder for clamping the pivot bar to insure a definite angular position of the mop head tothe handle axis.

These and other objects and advantages of the invention will be apparent from the description thereof to follow taken in connection with the accompanying drawing in which- Figure 1 is a plan view of a mop embodying the invention.

Figure 2 is a side elevation of the lower end of the mop handle and mop holder attached thereto, partly in section on the line 2-2 of Figure 1.

Figure 3 is a plan view of the mop holder shown in Figure 1 having the sheepskin protector in opened position.

Figure 4 is a side elevation of Figure 3 showing the mop holder with sheepskin protector fully attached thereto and the pivot bar clamped therein.

Referring to the drawing, Figure 1 shows a floor mop comprising a mop head consisting of mopping material I0 intertwisted between wires II which are formed into a loop and provided with a straight portion Ha forming a pivot bar adapted to be held and clamped in the journal part 2| of the mop holder 20. The mop holder 20 is preferably stamped and formed of a single piece of sheet metal and consists of a tubular cylindrical rear portion 22 adapted to surround the lower end of a mop handle I2 and provided with two outwardly extending parallel flanges 23 which may be drawn towards each other by a small carriage bolt 24 having its square portion lodged in a corresponding aperture of one of said flanges, and a wing nut 25 pressing against the outer face of the other flange. The middle portion 20 of the mop holder consists of the flat plate portion 20a which widens out towards the front of the holder and a conical portion 20?) between into which the pivot bar Ha is inserted. This portion 2| is formed by bending the sheet metal plate upward in front of the point of the taper portion 2% and rearward above the same to form the clamping plate 2% extending rearward above the front part of the taper portion Zflb. Clamping plate 26 is provided with a small aperture to accommodate the clamping carriage bolt 27 which also extends through a square aperture in the tapered portion 25b, in which the square part 27a of the bolt is lodged. To arrange bolt 21 perpendicularly to the normal direction of clamping plate 26 the sheet metal of plate 26 surrounding the bolt 2'! and its head is indented by deforming the tapered portion 2% at Zllc so that at that point it is parallel to clamping plate 26 and the head of bolt 21 is concealed within the recess of the tapered portion 20b so formed, as'shown in Figure 2. Outside of clamping plate 25, bolt 21 carries a hexagon nut 28 for drawing plate 26 towards 20c and thereby contracting cylindrical portion 2| and clamping pivot bar Ha; therein. It has been found through experiment however that no secure clamping of the pivot bar can be efiected in that manner because the cylindrical portion of sufficiently stiff sheet metal does not provide sufficient resiliency for clamping purposes and permits an unwanted rotation of the pivot bar within its cylindrical holder. To avoid this disadiustment, plate 28 is provided in front of nut 28 with a resilient tongue 30 preferably formed integral with plate 26 by cutting a V shaped slot 3| therein and bending the metal enclosed by said slot in a slightly downward inclined direction as shown in Figures 2, 3 and 4. The spring so formed impinges upon pivot bar |a in tightening nut 29 long before the cylindrical portion 2| starts any binding action and when the pivot bar a. is clamped the tongue 30 securely holds that bar and prevents disadjustment of the angular position of the mop head in case of looseness of the pivot bar |a in the cylindrical portion 2|.

To prevent injury to furniture or other articles in mopping floors by the metal parts of this mop holder, the front parts of the holder are covered by an elongated piece of sheepskin 32 with the fleece thereon, or other compressible resilient material which is provided with apertures 33 at opposite ends. This sheepskin covering is folded over the cylindrical portion 2|, plate 26 and the front part of the conical portion 20b. One end of the covering is placed under the head of bolt 21 which passes through one of its apertures to be pressed against part 26a and the other end is passed over the point of the same bolt to lean against plate 26 and pressed against this plate by nut 28.

I desire to make it understood that changes in the details of this invention may be made without departing from the principle thereof and I wish to be limited only by the state of the prior art and the appended claims.

I claim:

1. A handle connecter for pivotally fastening a mop to a handle consisting of a tubular rear portion having parallel flanges thereon for contracting said tubular portion, a journal at the front end of said connecter transversely to said tubular portion, a clamping plate extending from said journal, a pivot bar in said journal, a midle portion connecting said journal integrally with said tubular portion, clamping means extending through said clamping plate and said middle portion for contracting said journal and a resilient member formed integrally with the clamping plate extending into said journal to engage said pivot bar when said journal is being contracted by said clamping means.

2. A handle connecter for mops comprising a split tubular member adapted to detachably engage the inop handle, an extension on said tubular member formed integrally therewith and terminating in a loop at its outermost end for receiving a portion of the frame of the mop head and a tongue member formed integrally on said turned portion and adapted to engage the frame portion to prevent turning of said frame portion in the loop.

3. A handle connecter for mops including a split tubular member adapted to detachably engage one end of the mop handle, an integral extension formed on said tubular member, said extension terminating in a loop portion at its outermost end for receiving a portion of the wire frame of the mop head, a V-shaped tongue mem ber formed integrally on said extension and projecting into the loop to engage the wire frame and a bolt and nut connection between the outward and inward portions of the extension for pressing said tongue member against said wire frame.

4. A handle connector for mops including a split tubular member adapted to detachably engage one end of the mop handle, an integral extension formed on said tubular member, said extension terminating in a. loop portion at its outermost end to receive a portion of the wire frame of the mop head, a tongue member formed integrally on the extension and adapted to engage the wire frame, a protecting cover around said looped portion and tongue member and a bolt passing through said extension and cover to hold the cover on the looped portion and tongue member.
