Application filed March 15, 1915.

To all whom it may concern:

Be it known that I, KAY T. TANAKA, a subject of the Emperor of Japan, residing at Salt Lake City, in the county of Salt Lake and State of Utah, have invented certain new and useful Improvements in Hardwood-Floor Mops; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to mops designed for the purpose of polishing hard wood floors, and cleaning the same, and one of the principal objects of the invention is to provide a mop comprising two revolving heads adapted to be used in connection with a long strip or mop cloth wound upon the revolving members and adapted to be adjusted to provide new mop surface at any time required.

Another object of the invention is to provide a mop head pivoted in a yoke connected to a handle, said mop head comprising two revolving members about which a long strip of mop cloth is wound, said members being arranged to be independently rotated, so that a new mop surface may be secured at any time.

The foregoing and other objects may be attained by means of the construction illustrated in the accompanying drawing, in which- Figure 1 is a top plan view of a mop made in accordance with this invention, and showing the handle portion broken away and a portion of the mop cloth also broken away, Fig. 2 is a side elevation of the same, Fig. 3 is a sectional view taken on the line 33 of Fig. 1, and Fig. 4 is a detail view taken on the line 4-4 of Fig. 1.

Referring to the drawing, the numeral 1 designates a metal yoke connected to a handle 2. The yoke 1 is provided with parallel arms 3, and a mop head indicated as an entirety by the numeral 4, is pivoted on screws or bolts 5 to the parallel members 3.

The mop head comprises the wooden cores 6, 7, said cores being connected together by Specification of Letters Patent.

Serial No. 14,482.

means of bars 8 at the opposite sides thereof, said cores being pivoted upon screws or pins 9 which extend through the bars 8 and into the cores 6 and 7. The bars 8 are supported upon tWo guide members 10 which extend across between the plates or bars 8 and between the cores 6 and 7. The arms 3 are spaced from the members 10 by a suitable washer at each end designated by the numeral 11. Connected to the opposite ends of the cores 6 and 7 are rectangular plates 12 having rounded corners 13. Connected to the guide members 10 are spring wires 14, said spring wires adapted to engage the 0pposite side of the plate 12 to insure proper relative positions of the cores, and to hold them in position when adjusted to present a clean mop surface as will hereinafter appear. The mop cloth 15 is in a long strip and is wound about the two cores with the intermediate portion passing over the guide members 10 as shown more clearly in Fig. 3. When it is desired to have a new mop surface, the core 6 is rotated to unwind the cloth and the core 7 is rotated to wind up the cloth, or vice versa, the spring wires 14 being spread apart by the rectangular plates 12 as the cores are rotated and holding the cores in parallel relation to provide a fiat mopping surface after the cores have been adjusted.

From the foregoing it will be obvious that a hard wood fioor mop or polisher made in accordance with this invention can be readily adjusted to present a clean surface to the floor at any time, and that the mop cloth may be reversed whenever desired so that both surfaces of said cloth may be utilized.

Various changes may be made in the details of construction without departing from the spirit and scope of the invention as de fined in the claims.

What is claimed is 1. A mop comprising a yoke, a handle connected to the yoke, a frame pivoted to the yoke, said frame comprising a central guide member, end plates, cores pivoted to vsaid plates, and provided with a strip of mop cloth wound thereon, said cores being independently rotatable, and means for holding the cores and mop cloth in position to present a flat surface to the floor.

2. In a mop, the combination of a yoke, a handle, a frame pivoted in the yoke, said frame comprising a central guide member, cores pivoted in the frame which is provided with spring Wire holders, rectangular plates connected to the ends of the cores to be enga ed by the spring wires and a continuous 10 str1p of mop cloth wound around said cores and passing over said ides.
