UNITED STATES PATENT oFFica I EDWARD ,w. BLOOMFIELD, on vanconvnn, BRITISH COLUMBIA, CANADA MOP Application filed. February 16, 1928. Serial No. 254,749.

This invention relates to improvements in devices for scrubbing and mopping floors, linoleums, oil cloths and like surfaces which have to beperiodically cleaned. Its object is the provision of a simply constructed and cheap fitting which supplies in a combination form a scrubbing brush, floor-mop, mopcloth and mop-cloth wringer, assembled in actual use.

a convenient manner, and so constructed as to take up the 11111111111111]. of space when not in The device is mountedupon a handle or stem by which it can be efiectively and conveniently applied to the floor or othersurface'to be cleaned and consists essentially of a handle carrying a clamp block to which a scrubbing brush is rigidly attached or clamped by means of bolts, a mopping cloth which is clamped between the scrubbing brush and the clamp block aforesaid, and a tightening or wringing attachment fastened to the handle, and so disposed as to be capable'of engaging withthe free end of the cloth, and imparting a twisting motionthereto, thereby squeezing from it the excess dirty water which accumulates thereon during the operation of mopping a'dirt-y floor surface.

The, details of my invention are more clearly described by the drawings forming part of this application, and in which:

' Fig. -1'is a general view orelevation of the device showing all the parts in'their relative position when the wringing is in progress.

Fig. 2 is a view showing the method of attachment of the scrubbing brush and mopcloth to the handle by means of clamp bolts and wing nuts. 7 I

Fig. 3 shows the construction of the wringing device provided at one end with a hook for engaging with the mop-cloth and applying the twisting or wringing motion thereto,

and at the other with a handle by which the rotary motion is imparted to the hook.

In these drawings 3 represents the scrubbing brush attached to the clamp block 4 i by means of the bolts 5. The mop-cloth 11 is doubled over lengthwise, the two free ends being brought together and clamped between the brush 3 and the clamp block 4, thus forminga loop which can be engaged by the .also through the handle, thus locating the 9 while they are in position in the frame 7,

hook 10. When required for use the cloth is immersed in a pail of soap and water solution in the usual way and then placed upon the floor surface, pressure being applied thereto by planting the brush 3 upon it.

When it is required to wring out the cloth 11 the free end or loop of the cloth is passed over the hook 10, which passes through a bearing in the frame 7 and is rotatable therein, its inner end being attached to one end 1 of a spiral spring 9, the other end of which is attached to the inner end of the crank member 8, which passes through the bearing in the tubular member 13, and also through the handle 6, being provided with a hand 5 grip 12 by which the necessary rotation is given to the crank member 8.

The spring 9 is wound left-hand, so that the strain of windingup or twisting the mopcloth 11 tends to tighten up the coils and not to spread or unwind the spring.

The ends of the bracket frame 7 are riveted to the tube 13 which surrounds the handle6 and the rivets pass through the tube and [51 bracket 7 definitely upon the handle 6.

The mop-cloth can be readily removed by slackening the wing nuts upon the bolts 5, and withdrawing the cloth, when a new one can be placed and secured in position. 30

The method of attachment of the spring 9 to the crank member 8 and to the hook 10 is shown in the sectioned part of Fig. 3. The inner ends of the members 8 and 10 are deformed or spread as shown at 14, and they are assembled in a mould in axial alignment with the ends of the spring 9. A cylinder of lead or Babbitt metal 15 is then cast around the members 8 and 9 and the members 10 and thus securing them rigidly together, so that the turning movement of the crank 8 is transmitted through the spring to the hook 10.

Having now particularly described my invention, what I claim and desire to be pro tected in by Letters Patent, is:

In a mop the combination comprising, a handle, a clamping member secured thereto, a second clamping member, a mop cloth in the form of a loop having its ends secured is.

between the two said clamping members, wringing means attached to said handle and comprising a hook for receiving the loop end of said cloth for wringing purposes, said book 5 being revolvable, said wringing device comprising a sleeve encircling and reinforcing said handle and providing a bearing for a hand crank transversely therethrough, a resilient wire in helical form terminating at 10 each end in a babbitted abutment and continued to form said hand crank and hook respectively, bracket means secured to said sleeve and adapted to receive and support said resilient wire.

15 In testimony whereof I aflix my signature EDWARD W. BLOOMFIELD.
