Letters Patent No. 111,161, dated January 24, 1871; antedated January 12,1871.

IMPROVEMENT IN MOP-HEADS.

The Schedule referred to in these Letters Patent and making part: oi the same.

This invention relates to a new and useful improvement in mop-heads, whereby they are made more useful and durable than they have hitherto been; and

It consists in making the jaws of the head in a serpentine or corrugated form, and connecting the fastening-bolt directly to the lower jaw, and swiveling the jaws to the ferrule ofthe handle, as will be hereinafter more fully described.

In the accompanying drawing- Figure 1 is a side view of the mop partly in s ectien.

Figure l2 is a side view of the lower jaw detached.

Figure 3 is an end view, showing the mop-head with the lower jaw removed. i

Figure 4 is a section ofiig. 1 on the line x x.

Similar letters of reference indicate corresponding parts. y

A is lthe upper and'B the lower jaw of the mophead.

G is the ferrule on the end of the handle D, which ferrule is a nut for the bolt E on the lower jaw, by means of which the jaws are fastened `or drawn together so as to 'hold the rags between them.

F is a socket cn the upper jaw, which the end of the ferrule enters, as seen in g. 1.

The ferrule has a groove near its end, and the socket F is open on its two opposite sidesl so that the ferrule may be fastened in the socket, and a swivel-joint be formed by neans of two smllwires, g g, which are passed through the open spaces in the Jsocket, (in the groove,) with their ends bent over onto the jaw, as seen in g. 3 so that `they cannot be drawn out either way. The bolt E passes through the lower jawand into the` end of the ferrnle, in which a screw-thread is cut, as indicated in fig. 1. v

The bolt E is flat, with the 'screw-thread cut on its edges,- aSseen in g. 2, and it passes through a mor-l tise in the upper jaw, of corresponding shape, so that the jaws always stand parallel with each other.

The jaws are serpentine or corrugated at their inner edges where they .shut together, so that the rags are tightly secured between them.

These mop-heads are madecf cast metal, and require no tting save the screw-heads. They are very simple, strong, and'durable, and can be produced as heaply as any others possessing thev same advan- Having thus described my invention,l

I claim as' new and desire to secure by Letters Patent- 1. The arrangement of wires g g opposite openings in socket F, and annular groove on the, forwardend of ferrule C, as and for the purpose specil'ied.

2. A lower jaw, B, having flat shank E threaded atthe end, aoxnbined with a swiveled upper jaw, to enable both to turn simultaneously and always preserve their relative positions.
