MOP
Filed Au 5, 1930 Patented July 25, 1933 PATENT ree) ARTHUR G. KOOTZ, OF MILWAUKEE, WISCONSIN MOP.
Application filed August 25, 1930. Serial No. 477,584.
The invention relates to mops.
lVhile mops with heads of sheet metal and provided with pivoted handles are: Well known in the art, the usual types of pivotal connections have not proven satisfactory in service. Usually the handle connector is pivotally connected to the head by a removable pivotboltand this has a tendency to become loose either in the head or the handle connector or both. The present invention has been designed to obviate these difliculties by providing a mop head construction in "which the pivot pin is formed wholly or in part by portions of the head itself, thereby providing an efficient pivotal bearing for the handle connector without increasing the cost of the mop parts.
The invention further consists in the several features hereinafter set forth and more particularly defined by claims at the conclusion hereof.
In the drawing; Fig. 1 is a plan view of a mop embodying the invention;
Fig. 2 is a detail sectional view taken on the line 2-2 of Fig. 1;
Fig. 3 is a detail sectional view taken on the line 3-3 of Fig. 1;
Fig. 4 is a plan view of another form of mop head provided with the invention, parts 9 being broken away;
Fig. 5 is a detail sectional view taken on the line 5-5 of Fig. 4;
6 is a detail sectional view, similar to 2, showing certain modifications.
5 Referring to the drawing, and more particularly Fig. 1. the numeral 7 designates the mop body, which is of conventional form, consisting of the strands 8 of yarn or other fibrous material which is secured in any suitable manner as by stitching to the fabric band 9. Mop material of this kind is used in connection with heads of various shapes such as triangular, round. or rectangular formation, and in Figs. 1 to 3 I have shown a mop head 10 of generally triangular shape formed as a sheet metal stamping having a depending peripheral flange 11 to which the mop body may be secured as by rivets that pass through the fabric reinforce portion of the mop body 0 and holes 12 in the flange.
In Fig. 4 I have shown a mop head 13 of generally narrow rectangular formation having depending-flanges 14 to which the mop body may be secured in the same way as is se cured to the flanges 11 of the head 8.
The subject matter of'the present invention .may be used in connection with sheet metal heads of the above described constructions or other suitable forms and consists in the forming of the pivotal hearing or pivot pin portion for the handle wholly or in part by portions of the head. In both of these forms this is effected by providing a bridge portion 15 formed from the metal of the head and portions of the head are punched out therefrom adjacent this bridge portion so as to be coextensive with the same and are bent with said bridge portion into tubular form so as to form a pivotal bearing or pivot pin 16 for the handle connector of the mop.
For heads made of relatively light gauge sheet metal a reinforcing metal plug or insert 17 is provided, about which these parts of the head are bent to form the bearing as'clearly shown in Figs. 2, 3 and 5. It will be noted from these views that the cut out portions of the head are bent around the plug 17 to a point adjacent each other as at 18. Prefera- V bly the pivotal hearing or pivot pin portion v thus formed is spaced to provide a spheroidally curved bearing face 19 and cylindrical ends 20. For heads made of heavier gauge sheet metal the reinforce 17 may be omitted and the pivotal bearing or pivot pin portion formed wholly of the head material as shown at 21 in Fig. 6.
The above described constructions provide very simple but extremely strong forms of pivotal hearings or pin portions for mops V nector, and as one example of a connector suitable for this purpose I have shown in Figs. 1 and 2 a handle connector formed of sheet metal comprising a socket portion 23 adapted to receive the handle 22 and split on one side with ears 24 on this side associated with a clamping bolt 25 to draw the operating parts of the socket into clamping engagement with the handle 22, said socket connection also having a pair of spaced jaws 26 curved at their outer ends to engage the spherically curved bearing portion 19 of the head, and held in adjusted clamping engagement therewith by a clamping screw 27 that extends through openings in the aws adj acent the pivotal bearing or pin portion and is provided with a wing nut 28 for tightening the jaws about the bearing.
Other suitable handle connectors may be used with the mop head herein shown so that the mop head and the handle may have angular adjustment or movement relative to each other to suit conditions of service.
Idesire 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:
. 1. In a mop, the combination of a mop head of sheet metal having integral parts thereof formed to provide a pivot pin portion, and a reinforcing member for said pivot pin portion about which said parts are clamped.
2. In a mop, the combination of a mop head of sheet metal having a portion of said head portion punched and bent to provide a pivot pin portion including an arched bridge portion connecting the ends of so id pin portion with the main portion of the head.
3. In a mop, the combination of a mop head of sheet metal having a portion of said head portion punched and bent to provide a pivot pin portion inciuding an arched bridge portion connecting the ends of said pin portion wi h the main portion of the head and means "for reinforcing said pivotal War ng.
4;. In a mop, the combination of a mop head of sheet metal having portions thereof punched and bent to provide a pivot pin portion, and ametal plug about which portions of said pivot pin portion are bent.
5. In a mop, the combination of a mop head of sheet metal having a bridge portion and oppositely disposed portions spaced "from each other by said bridge portion and bent inwardly toward each other and said bridge portion to provide a conically curved bridge integral with said head and forming a pivot pin portion for the handle connector of a mop handle.
