MOP CONS TRUCTI ON Filed Feb. 9, 1931 Patented July 4,1933

JOHN GLOVER, or. orrroAeo, ILLrnors MOP c'ons'rnucrron Application filed February 9, 1931. I serial No. 514,433.

The present invention relates to a mop and mop structure and has to do with a spreader and a strip of thrums and the means employed for and manner of-securing such strip of thrums to a spreader in aneat and effective manner. i

It is not, new to use a spreader about the edge of which is disposed a strip of thruins.

To provide a neat structure, however, has been an objective with the manufacturers of mops which until the present invention has not been attained. The'obj ects oi the present invention, therefore, are to provide a new and improved mop structure ;,a new and improved method of securing thrums to a spreader or head; anew and improved spreader for a strip of thrums and'an improved combination of spreader v and thrums. i 29 These objects, and such other objects as may hereinafter appear, are obtained by the novel construction, unique arrangement and improved combination of the several elements illustrated in theaccompa nying single sheet of drawingin which one form ofthe invention is illustrated.

- In said drawing:

Figure 1 is a plan view of a spreader with astrip of thrums attached, a part of the socket being brokenaway to show the indentation in the mop and the ends of the strip holding the thrums Figure 2 is a transverse section on the line 22 of Figure 1.

Figure 3 is a detail, in section, on the line 8-8 of Figure 1.

Like reference characters are used to designate similar parts in the drawing and in 3 the description of the invention which follows.

The several figures may be read conjointly.

The spreader shown comprises a sheet of metal or plate 10 which is articulated to pro- 4: vide a central longitudinal rib 11 for reinforcement and to facilitate the attachment of a mop socket 12 thereto. A mop socket 12 em- I ployed in the apparatus may be conventional as shown and includes means 13 for the angular adjustment of the socket and the ets 17 are driven through the thrums 20 and spreader and means 14 forsecuring the socket detachably to a mop handle (not shown).

The illustrated spreader or head 10 is'substantially triangular. The head could be of a metal strip suitably articulated instead of a sheet of metal pressed into shape orotherwise treated. At each cornerofthe head 10 as shown, the material of the head is turned upwardly to provide a tab or cornerpiece 15. Intermediate each tab 15 the material of the head 10 is articulated downwardly to provide a flange 16 for the purpose of receiving rivets 17 which are adapted to pass through a strip of thrums -18 later to be more particularly described. At the rear of the head 10 and beneath the socket 12 and in alignment with the central rib thereof llythere is an aperture or slot or cutaway, section 19 the purpose of which will now be made apparent. About the mop a strip of thrums 18 comprising thrums 20 secured by a strip of'cloth material or the like 21 to which said thrums are sewed. This construction gives a'binding edge of the strip 21 of suitable width beneath and from which the thrums 2O depend.

As a rule, the thrums'20 are arranged by gathering them at their centers, placing the strip2l over the outside thereof and supplying a double row of stitching one row 22 being adjacent the lower edge of the strip 21. This

stitching

22 and 23 is adapted to extend through the thrums 20. At its ends 24 and 25, the strip 21 is turned in, the

stitching

22 and 23 or other stitching or tacking holding the ends in a turned in position.

During the course of the manufacture of the complete mop, the strip 21 is attached to the head 10 extending round the triangular, member with the ends at the slot 19. Rivstrip 21 and through the flange portions 16 of the spreader 10. The two ends 2a and 25, of the thrums projecting outwardly at the rear I of the triangular spreader 10 until pressed into the slot 19. No mop prior to the present is known to have been supplied with a slot of the character described or for the purpose herein set forth. In other mops,the ends 24 and 25 are left loose, tied together or otherwise treated.

A suitable number of rivets 17 are disposed in the head, generally two on each side thereof. Such arrangement provides for a single rivet 17 on each side of the slot 19. Such rivets 17 are placed relatively near to the ends 24. and 25 of the strip 21.

When the rivets 17 shall have been placed in position, firmly securing the thrums 20 and strip 21 upon the spreader 10, the ends 24 and 25 of the thrums 20 and strip 21' are forced inwardly of the slot 19. The two ends 24 and 25 are compressible one upon another for insertion thereint-o and to firmly secure said ends 24 and 25 in position. Such assembly makes a neat joinder therebetween, doing away from the unsightliness of the heretofore common methods of attaching a strip to a head, and remedying the heretofore unfinished appearance of a mop of the type described.

The indentation or cut-out portion 19 could be differently disposed, but experiments show that it is best adapted to be situated immediately beneath the mop handle socket 12 and at the rear of the mop, where thehardest wear comes upon the mop. By turning the ends 24 and 25 inwardly, the thrums 20 at the rear of the mop are multiplied and thus give protection to the spreader 10 and cover the spreader 10 most thickly at the point where it is most frequently closely in contact with the article or surface over which it is moved. The doubling of the thrums 20 at the heel of the head 10 affords complete protection to the surfaces of the objects upon or over which the mop is moved.

I claim:

1. A mop head of selected geometrical con figuration having a marginal indentation,

' and a strip of mop material comprising thrums having a binder at one edge thereof,

said bound edge of the material being arranged about the periphery of said head with the free ends of the bound edge extending into the said marginal indentation, the marginal indentation being of a width less than the normal thickness of the free ends of the bound ends of the mop material inserted thereinto.

2. A mop head of selected geometrical configuration having a marginal indentation, and a strip of mop material about the periphery of said head with the ends of said strip in said marginal indentation, the marginal indentation being narrow in relation to its depth and being of a width less'than the normal thickness of the two ends of said mop material.

3. A mop head'of selected geometrical configuration having a straight side to form the heel thereof, there being in said mop head a slot with opposed edges extending inwardly at substantially right angles to said straight side, thrums, a strip of material for holding said thrums, said strip being disposed about the periphery of said head with the ends of said strip terminating in said slot, said slot being narrower than its depth, and means for holding said strip on said head with its ends in said slot.

4. A mop head of selected geometrical configuration having a heel, there being a marginal slot in said heel, thrums, a strip of material for holding said thrums, said strip being disposed about the periphery of said head with the ends of said strip terminating in said slot, the width of said slot being less than the normal thickness of the ends of said strip, and means for holding said strip on said head with the ends of said strip in said slot.
