LOCKING DEVICE FOR MOP-HOLDERS.

Specification of Iietters ratent.

Patented Au. 3, 1915.

Application filed July 24, 1914:. Serial No. 852,809.

To all whom it may concern Be it known that I, Josnrn T. VVILSON, a citizen of the United States, residing at Clayton, in the county of Gloucester and State of New Jersey, have invented certain new and useful Improvements in Looking Devices for Mop-Holders, of which the following is a specification.

My invention relates to new and useful improvements in mop holders and as its principal object aims to provide a device of this character in which the mop rag or cloth is detachably connected to the staff or handle of the device by a simple and efficient fastening device.

More specifically my invention aims to provide a fastening device for mop cloths which consists substantially in two co-acting elements, one of which is so constructed that it serves as the receiving frame for the mop rag and the other of which is in the nature of a rod-like catch or retainer which is mounted on the handle and is movable into either operative or inoperative position with respect to the rag receiving frame so that this element may be either secured to or released from the handle. v

Another object, and one of equal importance with the foregoing, is to construct both the retaining rod and the rag receiving frame with such regard to proportion, numher and arrangement of parts that they may be cheaply manufactured, will be durable and efficient in service and may be easily and conveniently employed in attaching almost any form of mop cloth to a handle.

The above recited and other incidental objects of a similar nature, which will be hereinafter more specifically treated, are accomplished by such means as are illustrated in the accompanying drawings, described in the following specification, and then more particularly pointed out in the claims which are appended hereto and form a part of this application.

With reference to the drawing wherein there has been illustrated the preferred embodiment of my invention, as it is reduced to practice, and throughout the several views of which similar reference numerals designate corresponding parts, Figure 1 is a perspective view illustrating the receiving frame as applied to the handle and disclosing particularly the manner in which the retaining or looking rod engages the frame for holding it in operative position; Fig. 2 is a longitudinal section taken medially through the handle and illustrating the interior arrangement. of the stem portion of the rag receiving frame and locking rod with respect to the handle of the mop; Fig. 3 is a detail perspective view illustrating the mop rag vor cloth receiving frame in disassembled position with respect to the handle and locking rod.

In the embodiment of my invention illustrated in the accompanying drawings the mop includes as its essential features of construction, a mop cloth receiving frame 10, a locking rod 11, a staff or handle 12 and a metallic sleeve 13, which latter member embraces the terminal of the handle and acts to hold the member 11 against accidental displacement therefrom.

The mop cloth receiving frame 10 is preferably formed from a single. length of resilient wire of relatively heavy gage. This length of wire is bent in the manufacture of the frame at an approximate central point indicated at 14. The two strands of wire thus produced are twisted one about the other to form a stem indicated at 15. At the terminal of this stem portion 15, the

two strands are directed at right angles as at 16 and are then again bent at an approximateright angle to produce the arm portions 17. These portions 17 are arranged preferably to extend in substantial parallel relation to the member 15, as will be readily observed upon reference to either Figs. 1 or 2. It will now be seen that there is formed on the terminal of the stem 15 a substantially U-shaped frame which is defined by the two members 16 in connection with the arms 17 The two strands of wire as previously explained are produced by the initial bending of the wire at its approximate central point, are again bent as at 18 and then directed at right angles to the arms 17. The bars 19, which result from this bending of the strands, extend in opposite directions with respect to the member 15 and are normally disposed in severe frictional contact with each other at their intermediate portions by means ofthe resiliency of the material from which the member 10 is formed. The extreme terminals of the bars 19' are bent upon themselves forming the double portions indicated at 20. These members 20 act as terminal abutminal retaining finger 23.

tained by thus disposing the bars 19 will.

hereinafter be more particularly pointed out in that portion of the specification devoted to the description of the locking rod. The locking rod, which has heretofore been designated as an entirety by the numeral 11, is similarly to the frame 10, formed from a single length of resilient wire, which is bent toproduce a relatively long body portion 21, a terminal locking ring 22, and a ter- The member 23 is substantially arcuate in shape and lies in a plane at right angles to the body portion 21 of the rod. The locking ring 22 is with respect to the member 2-1 similarly disposed.

The actual construction of the frame 10 and locking rod 11 being thus disclosed, it now remains to describe the manner in which they are applied to the handle 12.

For this purpose reference will now be had particularly to Figs. 1 and 2, in which it will be seen that the stem portion 15 of the frame 10 is designed to seat within a metallic tube 24, which is let into the terminal of the handle 12. The rod 11 is applied to the handle 12 by disposing the body portion 21 in a longitudinally extending groove 25, which is formed in the face of the rod. This groove is in depth slightly less than the diameter of the member 21, so that the holding sleeve 13 will frictionally engage with the member 21 in such manner as to yieldably hold it against ing finger 23 to bring the ring 22 into engagement with the two members 16 at their junction. At this point it may be well to explain that the body portion 21 of the locking rod is of such length that it will be necessary for the operator to exert considerable'pressure against the finger 23 in order to bring the locking ring 22 into the proper engagement with themember 16.

When the ring 22 is engaged with the member 16 in the manner shown in Figs. 1 and 2, the member 23 is completely received within the groove 26, so that there willbe no liability of the terminal of the member 23 snagging or engaging with disastrous results any element foreign to the mop.

It will now'be seen that it is necessary to provide some means for; holding the stem 15 and consequently the frame 10 with respect to the handle 12. For this purpose I have cut away the upper edge portion of the sleeve 13 in such manner as to form a pair of diametrically opposed stop shoulders 27 As will be seen in Fig. 1, these shoulders are engageable by the portions 16 of the frame 10 and thus serve to hold the frame againstv rotation.

It will also be observed that the members 16 in'connection with the members 17 constitute in reality a substantially U-shaped keeper member Which co-acts with the lock ing ring 22 in forming a separable fastening device by which the frame 10 is detachably secured to the handle 12, and that the two members 17, constitute a double support for the body of the mop frame, greatly increasing the rigidity thereof.

In reduction to practice, I have found that the form of my invention illustrated in the accompanying drawing, and referred to in the above description as the preferred embodiment, is the most practical and eflicient; yet realizing that it may be necessary in some instances to subject the frame 10 and'locking rod 11 to slight modifications, in order to adapt the device for use under varying working conditions, I desire to emphasize the fact that various minor changes in the details of construction and arrangement of parts may be made without departing in any way from the basic principle of my invention as defined in the'appended claims.
