6 Claimsl (Cl. 15-152) fm curing a metal head to a handle.

A still further object of the invention is in the provision of a mop head made from a-single blank of material cut and formedto provide a mop head with overlapped handle embracing pro- ;3133 jections having handle piercingtangs.

In the accompanying drawing illustrating pre- 'fe'rred embodiments of the invention,

Fig. v1 isa side elevation of a mop constructed 'in accordlance with the principles of this in- '20 vention;

Fig. 2 shows a blank from which one of the 'heads is made;

Fig. 3 is an end elevation ofv the head as shown in Fig. l;

25 Fig. '4 is a section .taken on the line 4-4 of Fig. 3.;

Fig. 5 is an end elevation of. a'head showing a i modified form of clinching'attachment; and

Fig. `6 is .a section taken on the line 6-6 ofv Although this invention is particularly described in my U. S. Patent No. 2,164,395, of July 4, 1939, for Mop holder, of which it isa continuation in part, as applied to a head for a mop, a 35 similar interlocking attachment may be used for connecting the heads of other utensils at the end of a stick, such as rakes, hoes, and any other implement in which it is desired to securely attach a metal part to a wooden stick or handle.

' 40 The mere clinching of the edges of opposte side members into a supporting stick or handle is not usually sufiicient to hold a metal head securely connected to a stick. This is particularly true where the implement is subjected to severe 45 pushing, pulling and' torsional strain, and is more lever 43.

different points around the stick, with the at- .tached portions overlapped or staggered at opposte sides and also clinched into the handle itself at spaced distances and in different directions so 'that a portion of the handle between the in-`l serted tangs is in fact interlocked so that there is lesstendency for the head to loosen even under great strain and it will be held tightly in place.

, Referring now more particularly to thev drawings, a mop head 'l is attached at the end of handle or mop stick 8 and a mop cloth 9 is clinchingly held in a'bottom groove ll] of the head by a lclarnping Wire i I, the extremities |2 of which are bent and engaged in opposite sdes of attachingv Interposed between the clamping lever' and'the head and surrounding the stick is an extending coil spring li, one end held in connection with the lever by an eyelet |5 through which it extends and the other end of the spring held in connection' with the head by a tongue iii pressed out of the metal of the head and clinched over the head of the spring Wire at this end,

The location of the lever and its attachment to the spring is such that when pressed downwardly against the handle 8 about the eyelet |5 .as an axis it draws thel clamping wire II tightly within vthe groove ID, binding the mop cloth 9 yieldingly therein and holds the lever [3 yieldingly` against thestick from which it can be disengaged only by manually raising the outer or handle end of the lever from the stick.

The head is made up of a blank of sheet metal cut as shown in Fg. 2, and shaped by suitable dies as shown in Fig. 1. At opposite ends of the blank are notches 18 which define the clamping wire groove and at opposite sides of the blank are side projections |9 connected with the main portion of the blank by reduced neck portions and each having opposite reduced projections 20 and Zl adapted to be bent at the extremities to form 40 tangs inserted under pressure into the mop' stick, these projections lying one above the other as shown more clearly in Fig. 3 so that they are staggered or overlap. The eXtremitiesZZ which are inserted may be sharpened or pointed at the ends but preferab-ly are inserted axially andv since the projections 20 and 2| of opposite sides overlap the extremities 22 as shown in Fig. 4, substantially engage a Wedging projection between them on each side of the stick which tend to hold the head clamped more firmly at the end of the stick.

Instead of overlapping to the extent shown in Figs. 3 and 4 the projections of the sides may overlap only slightly as shown in Figs. 5 and 6,

in which case the inserted tangs or extremities 24 are substantially in alignment. Even in this form the extremities are preferably clinched inwardly and oppositely as indicated in Fig. 6, so that they will grip the stick more firmly and will have a wedging or divergent attachment therewith. In both cases the overlapping projections of the sides 19 serve to accurately position the side projections and locate the insertion of the inwardly bent tangs at the extremities of the projections. The parts of the opposte side projections which overlap also substantially interlock at the sides when the tangs are inserted. and thus strengthen the attachment of the head to a stick. When the tangs are out of alignment at each side of the stick the tendency is to prevent the stick from splitting and When the extremities are inclined oppositely as shown in Fig. 6, they tend to grip the opposte sides of the stick more firmly between each of the opposte sides of the blank.

I claim:

1. A mop head fastening in combination with a handle, comprising a single sheet of metal bent in the center and having complementary handle socket portions formed at opposte sides, each side portion having projections extending oppositely at different distances from the center of the blank and overlapping the opposte side projections at different distances from the center When they are bent toform a socket, and the extremities of both projections at each end being turned inwardly, piercing the handle, the handle piercing projections being out of alignment at each side of the handle.

2. In a mop stick fastening, a cross head of sheet material having opposte complemental Sections forming a socket to secure the head to the stick, each of the socket forming Sections having opposte projections at different distances from the crosshead With handle piercing tangs at both extremities, the projections of the opposite sides being staggered so that they will overlap at opposte sides of the stick, and the tangs being acutely bent to enter the stick for securing the head firmly to the stick by the overlapping engagement of said projections.

,3. A mop stick fastening comprising a stick and metal bent to form opposte complemental sections for forming a socket to secure the head to the stick, the socket Sections both having opposte projections at different distances from the head with inwardly turned tangs at the ends inserted into the stick, the tang of one section overlapping that of the other along the stick and providing an interengagement With the stick Sections between the tangs at opposte sides for interlocking the said opposte complemental Sections in positioning and firmly attaching them to a stick.

4. A mop head fastening comprising a stick and a cross head of sheet material therefor, the sheet material being bent to provide complementary Sections forming a socket to secure the head to the stick, each section having opposte projections at different distances from the head along the stick with tangs at the ends, the outer tang at the end of one section overlying the inner tang at the end of the other section along the stick, and the'adjacent tangs at each side of the stick being inserted therein at different angles to bind lying the inner projection of the other section' along a handle, the corresponding projections of opposte Sections abutting each other and both completely surrounding the handle When the tangs are inserted in the handle.

6. A mop handle fastening means comprising a Sheet metal head bent at the center and opposite complementary socket portions each bent semi-circularly and having opposte projecting portions at different distances from the center and one overlapping the other along the stick With bent tang portions at the opposte ends, the portions in alignment along the stick both embracing the stick and abutting the tangs which extend into the handle, the adjacent tangs at the same side being at different angles to grip the handle therebetween.
