6 Claims.

The present invention relates to a structure for a resilient bail and for an improved cross head and socket to be used with a mop.

The objects of the invention include, among others, the provision of the following:

An improved resilient bail for use with a mop;

A structure for a mop by which the bail and the bail spring are incorporated into one element;

A new cross head for a mop; and

A novel combination of a cross head and a socket.

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 which constitute the single form of the invention shown in the accompanying drawing, hereby made a part of this invention, and in which,

Figure l is a plan view of a mop embodying the subject matter of one form of the present invention;

Figure 2 is a diametric section of the mop end, the stick being shown in elevation and a part being broken away to show the attachment of the cross head to the stick; and

Figure 3 is an end View of the mop shown in Figure 1.

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

The device comprises a stick I 0 which has a two piece cross head at the end thereof. The cross head includes a socket part that may be stamped from a sheet of metal. The socket forming part includes a cross bar support, and a reinforcing web at each side. Such part is formed from one sheet of material. The sheet of material in plan View has a bell-like shape. At its center, it is transversely slit by three parallel cuts. The material at each side of the slits or cuts is sprung or punched out in opposite directions.

In this manner, a socket is formed. The socket comprises a Senn-cylindrical section II having an offset part I2 for anchoring a lever, a second semi-cylindrical section I3 opposite punched out, a third semi-cylindrical section I4 substantially parallel with section I I, and a fourth semi-cylindrical section i5 opposed to sections II and I4 and parallel with section I3. The oiiset section I2 has a transverse transfer slot for anchoring a lever later to be described. Sections II and I 4 on one side of the stick I0 and sections I3 and I5 on the oth-er side thereof provide a substantially cylindrical socket in which the stick I0 is firmly held by a tang S6 struck from section I3 and extending inwardly radially of the stick.

Reinforcing ribs Il are formed at each side of. the socket forming plate and diverge outwardly as the outer end of the cross head is approached, The socket forming plate has at its outer end a series .of tangs, eight in the present instance. The tangs are designated I8 and I9.

A cross bar 20 having a central seat groove lo 2| and side sections 22 has apertures 23 into which the tangs I8 and I9 are inserted. Tangs I8 and I9 are crimped or clinched to maintain the cross bar 20 rmly upon the socket forming plate, the tangs I8 being turned in one direction 15 and the tangs I 9 turned in the opposite direction.

The outer ends of the cross bar 20 are notched at 25. A bail having the cross section 26 extends across the bar. The cross section 26 occupies the 20 groove 2I when the mop is closed. The bail comprises side sections 2l, and inturned Ushaped sections 28 the legs of which are parallel to cross section 26. The material of the entire bail is integral and of spring steel cr similar material and it is further bent at each side by the insertion of another U-shaped reversed curve 29, one leg of which is also the leg of section 28. The other leg terminates in a slightly bent section 3Q. Section 30 terminates in a hook 32. 0

A lever member 33 of irregular half round configuration is apertured at each side at 34 to receive the hooks 32. The lever comprises sheet material bent into compound curves and has a folded over-section 35 at its front end, the material of the folded over-section 35 penetrating the slot in the oli-set section I 2. Connection between lever 33 and section I2 provides a pivot for the lever 33 upon the end of the rmly anchored socket forming member. 40

The o-i-set of section I2 in which the lever 33 is pivoted provides a dead center for lever 33 in a position away from the stick I0. On inward movement, the lever passes the dead center whereupon the lever snaps into a closed position 45 along the stick I0. p

Sections

28 and 29 of the bail compensate for the separation of the cross head and bail when Y swabs or thrums are held in the mop. The bail and bail spring thus are in a single piece of spring 50 such material firmly, whether there is a small cr a large quantity of it.

One method of assembly for the mop is to unite the cross head socket forming part and lever 33 after which the socket forming part is applied t the stick. After the socket has been rmly attached by the insertion of the tang i6 into the material of the stick, the bail is positioned by inserting hooks 32 into the apertures 34 of the lever 33. The mo-p is then ready for use. If preferred, the bail may be attached to the assembly before the stick is inserted into the socket.

- For use, the lever 33 is irst pulled away from the stick. The bail is thus moved from contact with the cross head. Thrums or swabs are inserted between the cross head and the cross section of the bail. The lever 33 is then angularly moved toward the stick lo and after it passes a dead center it snaps into place.

Toy release the swabs or thrums, the lever 33 is angularly moved away from the stick I0. Such movement frees the cross section ofthe bail from the cross head and admits of the removal of the swabs or thrums.

Y What is claimed as new and is desired to be rsecured by Letters Patent of the United States is:

1. In a mop head organization of the type employing a stick, having on one end thereof a sheet metal socket carrying one element of the mop clamp, and a lever actuating the n other mop clamping element; the improvement whereinr the sheet metal socket has a portion extending 1aterally away from the peripheral plane of the stick, said outwardly bent portion being slotted to provide a pivot bar transverse to said stick, the lever having a tongue portion adjacent one end extending through said slot and around the pivot bar, and into the space formed by said outwardly bent portion of the socket to pivot the lever to the socket. i

2. In a mop head organization of the type employing a stick, having on one end thereof a sheet metal socket carrying one element of the mop clamp, and a lever actuating they other mop clamping element; the improvement wherein the sheet metal socket has adjacent the inner end a portion extending laterally away from the peripheral plane of the stick, saidv outwardly bent portion having an opening adjacent said inner edge, the lever having a tongue portion adjacent one end extending through said opening and into the space formed by said outwardly bent portion of the socket, and having a bent portion thereon to pivot the lever to the socket.
