ATTORNEY;

Patented .lune 13, 1933 nir STATES ARTHUR c. xoomz, or MILWAUKEE, WISCONSIN Application filed June 17,

The invention relates to mops and more particularly to those types of mops wherein a cloth or swab is held between a relatively r fixed and movable jaw mounted on the operating handle. 1

Mops of the type above described usually have a fixed jaw formed as a casting or of several pieces of sheet metal riveted together and a movable jaw connected to a clamping lever mounted on the mop handle, a spring being interposed between the lever and fixed jaw. One of the objects of this invention is to simplify the construction of the fixed jaw by forming it of a single piece of sheet metal thereby dispensing with all riveting operations.

In mops of the above described type considerable difficulty has been experienced in anchoring the fixed jaw to the wooden handle and preventing the usual fastening means such as staples from'pulling out. Another very important object of the present invention is to provide a fixed aw member of sheet metal wherein the end portion of the socket is provided with integral depending spurlike projections adapted to be driven into the end of the handle to securely anchor the fixed jaw thereto and absolutely prevent any tendency for this jaw becoming loose.

"p The invention further consists in the several featureshereinafter set forth and more particularly defined by claims at the conclusion hereof.

In the drawing, Fig. 1 is a plan View, ofa

mop structure embodying the invention, part of the handle being broken away; Y

Fig. 2 is a side elevation of the structure with the jaws in open position;

N Fig. 3 is a detail front end view, parts being broken away;

Fig. i is a detail sectional view taken on the line 4-4 of Fig. 1.

In the drawing, the numeral 5 designates the usual wooden handle, 6 the fixed jaw memher, 7 the movable jaw, 8 the jaw operating lever and 9 the spring.

The fixed jaw 6 is made from a single piece of sheet metal which is folded upon itself and bent to provide complementary sidesections,

. so each of which have a half socketportion 10,

jaw portion 11, side flanges 12 which are clamped together by bending atongue 13 onv one of the side flanges over 'the adjacent flange, it being notedthat the jmedial bend of the sheet metal'piece'isat 14a, 'thegcenter 55 of the jaw, and thatjeach'side of the jaw is formed by reversely bending the inetjal to provide a" double thickness 'Thustlie whole of the fixed jaw is'formed of asingle piece of sheet metal'secured together without any rivets At the central portion of the jaw member it will be notedthatthe jaw portion 11 is omitted and that the stock at the top of the socket is cut or punched to provide driving lugs or spurs 15 which are bentover into 65 the upper end of the'socket and, when the socket portion of thejaw' member is fitted over the end of the handle 5, the lugs 15 are driven into the end of the handle as shown.

in Fig. 4 and thus this fixed jaw isfirmly 7 anchored to the handle without the use of separate fastening means.

The movable jaw member 7 is'formed as usual of heavy gauge metal wire adapted to cooperate with the groove of the jaw por l5 'tions 11 and be guided by the'end grooves 16 formed in said jaw portions and has hooked ends 17 engaging in the ears 18 of a sheet metal lever 8 whose inner end has H a pivot ear 20 encircling a part of the end '80 convolution of the spring 9 which at its other end is secured to the handle adjacent the jaw 6 by astaple 21 driven in the handle, the same here being shown as having one of its legs vpassing through an opening in the socket portion of the fixed jaw though this is not relied upon to firmly secure the fixed jaw to the handle as it has been found that where reliance is placed on such fastening means that the staple frequently tears out. 99 This staple however is sufficient to retain the spring'in position but the lugs 15 are relied upon to hold the aw 6 to the handle.

The mop operates similar to others of this type in that the mopping material is inserted between the open jaws and then the lever 19 is turned back to a position adjacent to the handle and due to the toggle action effected through the offset connection of jaw member 7 with said lever, the jaw members hold the mop material between them under a yielding pressure exerted through the action of the spring 9 on said lever and movable jaw.

I desire it to be understood that this invention is not to be limited to any particular form or arrangement of parts except in so far as such limitations are included in the claims.

What I claim as my invention is:

10 1. In a mop of the character described, a fixed jaw member comprising a single piece of sheet metal bent to provide jaw portions, a flange, a socket portion, and a driving lug extending into said socket portion and formed from stock between the jaw portions, said lug adapted to be driven into the end o a mop handle.

2! In a mop of the character described, a fixed jaw member comprising a single piece Of sheet metal bent medially of the jaw to provide complementary parts, each of said parts having separated jaw portions, a flange, a half'socket portion medially ofthe flange and a driving lug formed from stock between the separated jaw portions and inwardly bent to project into the socket formed by said socket portions, means for securing said complementary parts together, said lugs adapted to be driven into the end of the mop hand e,

In testimony whereof, I afiix my signature.

ARTHUR C. KOOTZ.
