6 Claims.

This invention relates to mops and particularly to so-called dry or dust mops, and has for its object the provision of means by which the mop head is detachably secured to the mop stick. The invention has particular reference to mops provided with actuating means by which the mops are shaken or vibrated to dislodge the accumulation of dust and dirt acquired by them during their performance of the dusting operation. Examples of such shaker mops are found in the patent to Spaeth No.1,785,536, and in my Patents Nos. 1,993,336 and 1,996,056.

Mops of this character are provided with shaking devices constituting a connection between the mop handle and mop whereby a movement of an actuating element, slidable on the handle, acts to vigorously shake or vibrate the mop head to dislodge the dirt and dust therefrom. These shaking devices generally ontlast the mop head and it is therefore desirable to provide the mop head with means whereby it may be easily disconnected from the handle and from the shaking device to enable a new mop head to be attached thereto when required.

The object of this invention therefore is to provide a detachable mop head of such construction that it may be easilyremoved without the use of tools, when worn, and a new one placed in operative position without requiring dismantling of the shaking device.

In the accompanying drawing, Fig. 1 is a plan view of a two-faced type of mop as used with a different form of shaking device; Fig. 2 is a sectional view on the line 2--2 of Fig. 1, looking in the direction of the arrows; Fig. 3 is a perspective view of the 'mop head frame used on the type of mop head shown in Figs. 1 and 2; Fig. 4 is a part of a modified form of mop head frame; and Fig. 5 is a sectional view through the double face type of mop shown in Fig. 1.

The structure shown in Figs. 1 to 5 inclusive shows a two-faced Inop, with a mop-shaking device. There, the mop handle is indicated at and is provided with a pair of llongitudinal grooves, one of which is shown at 2li in Fig. 1. A cord of cable 2l is movedin these grooves by a suitable sliding sleeve and at the lower end of the stick the cord extends `about a pulley 28 mounted to rotate in the walls of a casing 29. The elements just described are parts of the mop shaking devi-ce not claimed per se herein. The pulley 28 is secured upon a short shaft or spindle 36 which has its ends projecting out of the sides of the casing 29 for engagement with parts of the mop frame 3|. The mop frame 3|,

shown in perspective in Fig. 3, is preferably composed of a single piece of bent wire or rod and is formed with upper and lower triangular or heart shaped portions 32 disposed in substantial parallelism and which are integrally connected by the vertically disposed parts or struts 33. These vertical portions 33 are flattened as at 34 (Fig. 2), the flattened parts fitting into slots 35 formed transversely in the ends of the shaft 3U. The parts of the frame 3l on which the vertical portions 33 are provided constitute inwardly extending arms, and these arms normally tend to spring inwardly or toward one another to a limited extent, so that the flattened parts 34 of the frame 3| are held in constant engagement with the slots 35 in the shaft 3o. To disengage the mop from its engagement with the shaft 3B, it is merely necessary to pull the outer sides of the mop outwardly, as indicated in Fig. 1, this action causing the inwardly extending arms on the frame 3| to spread apart as indicated in dotted lines and become disengaged from slots 35.

In Fig. 4 a modified form of frame 3| is shown. There the vertical parts 42, which enter the slots 35 in the ends of the shaft 30, are located between the horizontally disposed bars 43 which are only sufficiently spaced apart so that they confine the ends of the shaft 30 between them and prevent it from shifting up and downon the parts 42 or in a direction transversely of the axis of the shaft 30. By this arrangement looseness of connection between the mop head and the shaking device is prevented.

The frame 3|, shown in Fig. 3, is preferably covered with mop material in the manner disclosed in Fig. 5. That is to say, the frame is disposed between two fabric strips 43 and 44. Confined between oneof the longitudinal edge portions of the strips are mop strands 45 maintained in position by the stitches 41, while a similar group of mop strands 46 is secured by switches 48 between the opposite longitudinal edges of the strips. To identify each of the mopping surfaces, it may be found desirable to color the strands of each of the groups l5 and 46 with different colors. For example, the group of strands indicated at 45 might be colored red, while that shown at 46 might be colored green. With the mopping surfaces so identified, the user of the mop may readily adapt it to dual use. That is, one of the surfaces may be oiled, waxed or impregnated with a polishing material while the other surface may be maintained in a dry state. The identification of the two mopping surfaces by the use of differently colored strands enables the user to immediately distinguish the oiled or waxed surface from the dry surface, and the utilization of identiiied mopping surfaces in a mop of this character provides the convenience of a cleaning and polishing mop in a single implement.

It will be seen that the two groups of mop strands and 46 are located in spaced relationship, connected only by the fabric strips 43 and 44. The maintenance of these two groups of strands in spaced relation is found desirable to prevent the oil, wax or other fluid with which one group of strands is impregnated from reaching the other group.

With the shaking device, partly shown in Fig. 1, the mop may be completely reversed to bring either of its working faces in contact with the floor.

With the structures shown, it will be apparent that the mop heads may be immediately disengaged from the mop stick and shaking device to permit the ready removal of a worn-out mop and the replacement of a new one without the use of tools or without requiring any undue handling of the dirty, worn-out mop.

What I claim is:

1. In a mop, a mop-head frame formed of bent wire and having upper and lower frame portions located in substantial parallelism, said fra-me portions being connected at one end by spaced vertical struts, and a mop handle provided with recessed projecting stud portions in which the vertical struts are held by the resiliency of the frame portions to detachably secure the frame to the stud portions.

2. In a mop, a mop-head frame formed of a single bent section of wire having spaced upper and lower frame portions located in substantial parallelism, said frame portions being inturned at one of their ends, the inturned portions on one frame portion being connected to the inturned portions on the other by vertical struts, a mop handle carrying a member at one of its ends mounted for oscillatory movement, said member having a shaft provided with slotted ends, the vertical struts tting into said slotted ends and held therein by the resiliency of the frame to detachably secure the frame to the shaft.

3. In a mop, a handle, a mop-head frame formed of bent wire and including a pair of similarly shaped vertically spaced frame elements, said frame elements being curled inwardly at one end, with the inwardly curled portions of one frame element connected to those of the other element by vertically disposed strut portions, a spindle mounted in the handle for oscillatory movement, said spindle having transversely slotted ends fitting the strut portions, the frame elements being shaped adjacent said struts to closely t over the ends of the spindle to prevent shifting of said spindle on the struts in a direction transversely of the aXis of the spindle.

4. In a mop, a mop-head frame formed of similar upper and lower wire loop members overlying and spaced from one another, said members having inwardly curled end portions lying within the respective loops, the ends of said inwardly curled portions being connected by vertically disposed strut members, said strut members having intermediate flattened surfaces.

5. In a mop, a mop-head frame comprising two substantially triangular loop members located in spaced superimposed relationship, said loops having inwardly curled ends connected by vertical strut portions.

6. In a mop, an oscillating shaft, a mop-head frame for connection thereto, said frame being formed of similar upper and lower wire members overlying and spaced from one another, said members having inwardly curled end portions terminating in vertically disposed strut portions for engagement with the oscillating shaft.
