s Claims. (01. 15-118) This invention relates to improvements in mops and more particularly to improvements in the so-called dry and oil mops used primarily for removing dust from floors, ceilings, and the like.

An object of the invention is to provide a mop of such construction that the head thereof can be agitated efficiently to shake dust therefrom.

Another object of the invention is to provide mechanism for agitating the head of the mop of such construction that it does not interfere with the normal operation of the mop.

A further object of the invention is to provide agitating mechanism of such construction that a minimum of operating parts are mounted exteriorly of the handle.

A still further object of the invention is toprovide a mop so constructed that the shaking mechanism can be disconnected from the head temporarily to permit reversal of the head.

Inone form of the present invention, a mop of conventional character is provided with mechanism for agitating the head thereof to permit shaking of dust from the head. In this type of mop, the handle is pivotally connected to the base" of the head in the usual fashion, and in addition, the handle is made hollow for a part of its length extending upwardly from its pivotalpoint. An arm is mounted on the base of the mop extending upwardly therefrom, and to this arm is pivotally secured a bent arm of arod which slides in the hollowed out portion of the handle.

Intermediate the ends of the handle, a slot is provided therein which communicates with the hollowed out portion, and a sleeve is secured around the handle and attached in any suitable fashion to the rod inside of the handle. By the arrangement of sliding rod and sliding sleeve, it is possible by holding the handle in one hand and rapidlymoving the sleeve backwardly and forwardly along the handle, to agitate the head of th'e mop to shake dusttherefrom. In conjuncto the handle near the head of the mop. The retion withthis type of mop, use may be made of mechanism for dispensing oil in the path of the mop, suchmechanism comprising a suitable receptacle for the oil, which receptacle is secured ceptacle is provided with a spring closed valve whichcan be operated by a cord to release the desired quantity of oil from the receptacle into the path of the mop. This cord, one end of which ing walls and ceilings. This type of mop is constructed of framework of such character that ordinarily the head can be completely rotated relative to'the handle. The handle is hollowed out as in the previous form, and is provided with a rod, one end of which is bent to form a crank. To this crank is attached an arm which also is attached to the frame near the extremity thereof. The attachment of the arm to the frame is removable so that the frame can be rotated sufiiciently toreverse the wiping surfaces of the mop after which the arm can be again secured to the frame. This arrangement permits the operator to shake the dust from the mop as in the previous form and at the same time permits the operator to reverse the mop so that each wiping surface thereof can be used infsuccession.

Other features, objects and advantages of this invention will become apparent by reference to the following detailed description taken in conjunction with the accompanying drawings forming a part of the same, wherein Fig, 1 is a perspective view of a mop embodying the agitating or shaking mechanism of the invention.

Fig. 9 is a section taken substantially on the line 99 of Fig. 8; and

Fig. 10 is a section similar to Fig. '7 of a further form of attaching mechanism for securing the agitating rod to the mop frame.

Referring now to the drawings and particularly to Figs. 1 to 4, inclusive, l0 indicates the base of a mop head constructed in the conventional manner and having secured thereto cords or other suitable fabric II. The base III has a part l2 bent upwardly as shown in Fig. 1, from which extends downwardly, ears M. A handle attaching member |5 of conventional character is pivotally connected to the ears M by means of a bolt and nut as is commonly the practice. Extending upwardly from the base I!) is an arm |6 made as a substantially flat bar.

Secured to the handle attaching member I5, is a handle I! preferably made of wood. This handle H is hollowed out centrally thereof for a considerable distance upwardly from the end attached to the member l5. Intermediate the ends of the handle l! is a slot l8 which communicates with the hollowed out interior of the handle below the termination of such hollowed out portion. slidable in the hollowed out portion in the handle is a rod I9, the end of which is bent as at 25 to form in effect a crank. The crank 26 is pivotally secured to the upper end of the arm i6 as shown at 2|. Slidably mounted on the handle I! is a sleeve 22, preferably but not necessarily, made of wood. This sleeve 22 is rigidly secured to the rod |9 by means of a set screw 24 which passes through the slot I8 into engagement with the rod I9. While the connection between the sleeve and the rod has been shown as being by the use of a set screw passing through the slot, any other suitable arrangement may be utilized.

Secured to the handle I! above the head of the mop is an oil container 25, preferably but not necessarily cylindrical, and made of some suitable metal. This oil container can be attached to the handle in any desired fashion. The upper end of the container is provided with a fill plug 26 while the lower end of the container is provided with a valve mechanism indicated generally at 21. The valve mechanism illustrated is composed of a cylindrical extension 28 of the container 25 which communicates with an enlarged cylindrical extension 29. This extension 29 is provided with an opening 30 near the lower end thereof. Fitting over the extension 29 is a closed end cylindrical member 3|, the upper edges of which may be spun over the shoulder between the extensions 29 and 28 as at 32. A coiled spring 34 is positioned between the closed end of the cylinder 3| and the closed end of the cylinder 29 serving to force the cylinder 3| downwardly. An opening 35 in the cylinder 3| can be brought into register with the opening 36 in cylinder 3|. An ear 36 secured to the cylinder 3| has an eye therein for the attachment of a cord 31, the other end of which can be secured to a stud 38 near the upper end of the mop.

The operation and use 'of this type of mop is substantially as follows. The mop may be used to wipe floors or other surfaces in the usual fashion. When it is desired to shake the mop to release dust from the surface contacting parts thereof, the operator may merely hold the upper end of the handle and then rapidly move the collar 22 upwardly and downwardly along the handle. This rapid movement of the collar communicates a movement to the head through the rod i9, the crank 26 on the end thereof, and the arm Hi. In other words, the head of the mop is moved rapidly from position shown in full lines in Fig. 1 to position shown in dotted lines in the same figure. If it becomes necessary a part of the handle attaching member I5 may be cut away as at 46 to permit extended movement of the crank end 26 of the agitating rod. This type of mechanism for shaking the mop head possesses advantages over any mechanism known to the art for producing a similar result. To begin with,

the only part on the mechanism outside of the handle is the simple sleeve 22, so that there is substantially nothing which will interfere with the use of the mop by the operator. It will be apparent that the handle may be moved readily through the guiding grip of the operator without interfering with such grip. Another advantage resides in the fact that the operator can determine exactly where the dust to be shaken from the mop will be deposited. It is only necessary to hold the head of the mop over a paper, for example, and then rapidly manipulate the shaking mechanism.

In the form of the invention shown in Figures 5 to 10, inclusive, a slightly different type of mop construction is utilized. This mop is made up of a frame member indicated generally at 50, which frame is constructed preferably of a single wire shaped to form two rectangles 5| and 52 substantially parallel to each other and spaced apart by means of a span of wire 54, which span is part of the single wire constituting the entire frame. A handle attaching member 55 has two leg portions 56 through which the span 54 passes. These legs 56 are spaced apart and have bearings substantially against the two parts 5| and 52. The handle 51 is secured to the attaching member 55 in any desired fashion. This handle 51 is hollowed out in the same fashion as the handle l1 and has slidable therein a rod 59, the lower end of which is bent to form a crank 60 in the same manner as before explained. A sleeve similar to sleeve 22 is utilized in this form of the invention but is not illustrated in the drawings.

The crank 60 may be flattened out for a part of its length near the end thereof for connection between the forks of an arm 6|. A pin 62 passing through the forks of the arm 6| and the end of the crank 6!) serves to pivotally connect these members together. The arm 6| is of a slight curvature as shown in Fig. 6, and has rounded extensions 64 extending outwardly from each side thereof at the base thereof. This base part of the arm, including the extensions 64, can be hollowed out as shown and two pistons 65 and 66 are mounted within the hollowed out portion. Upper and lower slots 6'! and 68, respectively, are provided in the extensions 64. A pin 69 passes through the piston 65, being seated in the slots 6'! and 68 while a similar pin 10 is similarly mounted in the piston 66. A spring H serves to force the two pistons 65 and 66 outwardly. The pistons 65 and 66 are provided with small pinlike extensions 12 and 13, respectively. Openings in the nature of round holes 14 are provided in the frame in the adjacent expanses of the rectangles 5| and 52. It will be noted that these openings 14 are provided at each end of the rectangles. The openings are so positioned as to accommodate the small pins I2 and 13. In the drawings, the fringe or fabric has been omitted from the framework for purpose of clarity.

The operation of this type of construction is substantially as follows. The two pins 12 and I3 are placed in engagement with a pair of openings 14 in the two rectangular sections 5| and 52. The engagement may be made by pressing the upper ends of the pins 69 and 10 toward the other thereby pulling the cylinders 65 and 66 inwardly. When the arm 6| has been properly positioned, pressure is released from the pins 69 and 10 with the result that the cylinders 65 and 66 are pressed outwardly by the spring 1|. This causes engagement of the pins 12 and 13 with a pair of holes 14. The mop can then be used to wipe walls or any other desired surface. If one wiping surface of the mop becomes soiled the other surface may be utilized by first disengaging the pins l2 and 13 from the pair of holes 14,

and then rotating the two sections 5| and 52 through substantially 180 degrees until the pins 12 and i3 can be moved into engagement with the other pair of holes i4. Of course, during the use of the mop and at any time, dust can be shaken therefrom by manipulating the shaking mechanism in the manner explained in connection with the previously described embodiment of the invention.

In Figures 8 and 9 a different arrangement for attaching the arm 6| to the frame of the mop is shown. In this construction the arm is made of a single strip of material, preferably of some metal having resiliency, which is bent into a hair-pin shape as at 80 to accommodate the end of the crank 68 by means of a pin 8| passing through the parts 80 of the arm and the crank 60. The ends of the hair-pin are flared outwardly as at 82 and are then bent upwardly into a substantially ogee curvature as at 84. The parts 84 may be made of greater width than the parts 82 if desired. Since this construction possesses considerable resiliency, it is possible to engage I opposite parts of the frame of the mop with indentations in the curved parts 84 as shown in Fig. 9. When it is desired to reverse the mop it is merely necessary to disengage the frame from the parts 84, rotate the frame through 180 degrees, and then spring the frame into engagement with the same parts 84.

A still further form of mechanism for attaching the crank to an arm is shown in Fig. 10. In this form, the arm 6| has hollowed extensions 64 in which are positioned similar pistons 90. Pins 9| pass through the slots in the extensions 64 to lock the pistons 98 in place. A spring 92 normally forces these pistons outwardly. Each piston 90 is provided at the outer end thereof overcoming the resiliency of the spring 92.

with an indented clip member 94 of such curvature as to permit the seating of a wire 95 formed as part of the frame shown in Fig. 5. Due to the shape of these clips 94 the wires 95 can be moved ing more than one wiping surface, the invention provides an arrangement whereby one surface can be brought into use; can be shaken when desired; and then the other surface can be brought into use and shaken if desired.

It'is to be understood that the invention is not to be limited to the illustrated embodiments, since it is capable of considerable modification, and consequently any limitations imposed thereupon are to be only those specified by the following claims.
