To all 'whom t may concern.

Be it known that I, LUTHER P. CnEAsY, a citizen of the United States, residing at Catawissa, in the county ofColumbla and State of Pennsylvania,haveg'nvented new and useful Improvements i'n ops, of wh1ch the following 1s a specification.

This invention relates to improvements in mops and has for an object the provlsion of a mop which may be either motor or hand operated and operated over a ioor or other surface to quicklyT and eifectually clean the latter.

Another object of the invention is the provision of a mop of the above character in which the mop per se will be thoroughly cleaned during the mopping operation to effectually remove dirty water before the mop again comes in contact with the iioor.

Another object of the invention is the provision of a mop of the above character which is simple in construction and operatlon land in which the mop per se may be readily removed and replaced.

With the above and other objects in view,

the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings Figure 1 is an elevation of a mop constructed in accordance with the invention.

Figure 2 is a section on the line 2--2 o f Figure 1.

Figure 3 is an enlarged fragmentary view illustrating the means for adjusting the auxiliary frame.

Figure 4 is an enlarged section on the line 4-4 of Figure 2. Y

Figure 5 is a similar view on the line 5-5 of Figure 2.

Figure 6 is a detail perspective view of the agitator roll. y

Figure 7 is an elevation showing a hand operated mop.

Figure 8 isl an enlarged fragmentary view of a portion of the mop belt.

Figure 9 is a similar view of a different form of belt.

Figure 10 is a section on the line 10-10 of F1 re 9.

Re erring to the drawings in detail where in like characters of reference denote corresponding parts, the invention is shown as Vcomprisingv a main frame which includes `substantla l triangular side members 15 which are connected by shafts 16, the latter supportlng flanged guide rollers 17. -Passlng over the rollers `17 is a belt 18 which forms the mop per se and which may be made of any suitable material. For exampleit may be made entirelyI of mop material, or 1t may be made of strips of mop material indicated at 19 in Figure 8 of the drawings and shown as arranged diagonally across a canvas or other suitable belt 20.. Where it is desired to use the mop for cement or other relatively rough ioors, or where an excess amount of dirt is to be removed, the lbelt may be in the form of a brush as indicated at'21 in Figures 9 and 10 of the drawings.

The belt 18 is yieldin ly forced into contact with the floor or ot er surface by compressible rollers 22' which are mounted between the side members 15 of the frame and which are supported upon shafts 23.

The frame is supported upon rollers 24 which are shown in detail in Figure 5 of the drawings. These rollers are adjustably secured to the frame and for this purpose are connected to substantially U-shaped brackets 25, having slots 26 therein for the passage of screws 27. Thumb 'nuts 28 are mounted upon the screws 27 and act to adjustably secure the brackets 25' to the frame.

Supported within the frame upon brackets 29 is a tank 30 which is adapted to containwater or other suitable cleansing liquid. This tank is substantially triangular and includes upwardly and inwardly inclined walls 31 whose fupper edges define a restricted top or mouth. The tank 30 is provided with a drain opening which is normally closed by a plug 32.

Located within the tank 30 is an auxiliary frame which includes spaced substantially triangular side members 33. These members are provided with extensions 34 having slots 35 therein, while pins or studs 36 extend from the side members 15 of the first mentioned frame into vthe slots 25 and act to guide the auxiliary frame.

The side members of the auxiliaryframe are connected by" shafts 37, the lowermost shaft having mounted thereon a flanged roller 38 around which passes the belt 18 so that the latter is guided downward through the j tank 30 and through the water within the tank. The opposite end of the auxiliary frame carries combined squeezing and

guide rollers

39 and 40, the latter being spring pressed as indicated at 41 so as to press upon the belt 18 which passes between these rollers and remove surplus water from the belt. The roller 39 has its shaft 37 arranged within the inner end of angular slots 42 provided in the side members 33 of the`auXiliary frame, so that this roller 39 may be removed for the convenient removal and replacement of the belt 18. The rollers 39 and40 are provided with flanges similar to the

rollers

17 and 38 which act to guide the belt.

The extensions 34 of the side members of the auxiliary frame are engaged by adjusting vscrews 43 which are mounted in the side members of the main frame as illustrated in detail in Figure 3 of the drawings. By

. means of these screws 43 the auxiliary frame may be adjusted to -adjust the belt. To maintain proper tension upon the belt the roller38 is mounted in floating bearings 44 which are movable in slots 45 provided in the side members 4'3 of the auxiliary frame, the bearings being yieldingly forced in. one direction by means of springs 46.

The belt may be either motor or hand operated. In Figures 1 and 2 there is illustrated a motor 46 which is supported upon the main frame and which is geared to the shaft 16 of one of the belt guiding rollers 17 by a train of gears 47.

Pivotally secured to the side members 15 of the main frame is a bail 48 to which is secured a handle 49 to provide means for moving the m'op over the surface to be cleaned. v

For the purpose of insuring the removal .of dirty or wastewater from the belt, the latter is engaged by an agitator. This agitator is in the form of a corrugated roller 50 which is mounted within the tank 30 and which contacts with the belt. Mounted upon the shaft of this roller is a grooved pulley 51 around which passes a drive belt 52. This belt also passes around a grooved pulley 53 mounted upon the shaft of the motor 36', whereby the agitator roll 50 will be rapidly rotated against the belt 18 to agitate the latter in its passage through lthe tank. By forming the tank 30 as shown in Figure 2, the water agitated by the roll 5() will be prevented from splashing out through the open top of the tank.

As shown in Figure 7, one of Ythe rollers 17'has secured thereon a grooved pulley 54 which is driven by a belt 55. This belt passes around a pulley 56 which is mounted `other changes in its form, proportions and 'minor details of construction and the right is herein reserved to make such changes as properly fall within the scope of the appended claims. j Having described the invention what is claimed is 1. A mop comprising a frame, wheels supporting the frame, a water tank mounted within the. frame and provided with a restrictedopen top, an endless belt, strips of mop material disposed diagonally across the belt -to provide a mop, guide rollers mounted within the lframe for guiding the belt horizontally along the lower portionV of the frame, spaced rollers of compressible materialengaging the horizontal portion ofthe belt to force the latter into active position, means for guiding the belt within the tank and means for driving the belt.

2. A mop comprising a frame, wheels supporting the frame, a water tank mounted within the frame and provided with a restricted open top, an endless belt, guide rollers mounted within the frame for guiding the belt horizontally along the lower portion of the frame to provide a mop, spaced yieldable means engaging 'the horizontal portion of the belt to force the latter into active position, a substantially triangular frame located within the tank and having slots at one corner thereof, pins extending from the first mentioned frame for entrance into the slots, rollers carried by the triangular frame for guiding the belt through the tank, adjusting screws carried by the iirst mentioned :trame and engaging the triangular frame to adjust the latter and means for driving the belt.
