5 Claims.

This invention has to do with a mop and relates particularly to an improved method for attaching a mop head to a handle.

The conventional way of securing heads for wet mops and the like to a handle is to slip a preformed socket or collar over an end of a handle and to drive a rivet or nail through an aperture in the socket or collar into the handle. Because of the independent connection of the nail or rivet and the mop head to the handle, the head and the nail or rivet eventually work loose to become troublesome and require repair.

When a rivet and tool socket once become loose on a handle, the handle is mutilated thereby and to again tighten the tool socket upon the hantile is at best but a temporary restoration. Often the handle is soaked in water to cause it to swell within the socket; but this too is an unsatisfactory way of tightening the grip between the handle and socket for when the handle again becomes dry it will no longer be tight in the socket.

It is an object of the present invention to provide a socket for a mop head which will not become loose from the mop handle from using the mop.

Another object of the present invention is the provision of a socket for a mop head and having integral parts for biting into a mop handle.

Another object of the present invention is to provide a socket for a mop or the like which is fabricated of parts having openings and prongs adapted to extend through such openings into the mop handle.

Still another object of the present invention is the provision of a socket for securing a tool to a handle, the socket being completely formed concurrently with its connection to the handle.

Another object of the present invention is the provision of an improved form. of anchorage for a mop head spring.

These objects and other desirable objects of the invention will be made apparent in the description hereinafter set forth with reference to the accompanying drawing hereby made a part of this specification, and in which:

Figure 1 is a plan view of a blank of sheet material adapted to be swaged and folded into a mop head embodying a form of the present invention;

Figure 2 is a perspective view of a mop head formed from a blank similar to that shown in Figure Figure 3 is a view of the mop head shown in Figure 2 but taken from. the opposite side thereof;

Figure 4 is a perspective view of the mop head shown in Figures 2 and 3 anterior to a handle member being attached thereto;

Figure 5 is a perspective view of the form of the invention shown in Figures 2, 3 and 4 with the cross head shown in Figure 4 turned upside down and sectioned on the line 5--5 of Figure 3.

Figure 6 is a fragmentary view of the mop head of Figure 3 and taken as indicated at lin 6- in that figure;

Figure '7 is a sectional View of the device taken at the line ii of Figure 6; and

Figure 8 is a sectional view similar to that of Figure 7 but of a modified form of the invention.

The same reference characters will be used throughout the drawing and in the following description for designating similar parts of the device.

Fold lines within the simple stamping It of Figure 1 are shown in dotted lines and there serve to separate different sections for forming respective parts of the completed mop head. At the central portion of the blank I0 is the main body I5 and at opposite ends of the blank are sections l2 which are deformable into complemental half-cylindrical socket sections as illustrated in Figures 2 and 3. In addition to the deforming of the blank iii to form the half-cylindrical socket sections l2, a series of stamping operations may be had to form a groove 13 within the main body ll.

Concurrently with the stamping of the sheet Hi, there may be formed a tongue [4 in one of the socket members l2 as well as slots l5. Upon the complemental semi-cylindrical member l2 there may be formed tongues or barbs [6. Figure 4. illustrates the complemental socket members in readiness to receive a handle member. The male and female members l6 and I5, respectively. are adapted for interlocking in the manner shown in Figures 6 and 7. By extending the prongs iii through the slots l5 and into the handle H, the parts l5 and 16 are made to serve additionally to holding the socket members together and to prevent the socket from turning upon the handle or sliding endwise thereof.

It is not imperative that all of the prongs or barbs l6 be upon the same socket member, it detracting in nowise from the spirit of the invention to place a prong l6 and an aperture [5 upon one of the socket members l2 and a complemental prong l6 and aperture 15 upon the other socket member for coaotion therewith. Figures 6 and '7 show in detail the manner of interlocking of the socket members having prongs upon one thereof and apertures I5 upon the other. Figure 8 illustrates a construction within which there is an aperture and a prong upon one of the socket members and a complemental aperture and prong upon the other socket member the corresponding parts being designated by the same reference characters as in the form of the invention shown in the other figures but with the letter a added.

The mop head comprises a loop l8 made of stifi wire or other suitable material and havin a straight section l9 for fitting into the groove l3. Thrums (not shown) or other material capable of absorbing water may be held within the groove H! by the straight section of the loop l8. Hooks 20 are formed within the oppositely positioned ends of the loop l8. A curved lever 2| has apertures 22 therein for connecting with the hooks 26 upon the ends of the loop I8. The curve in the lever member 2| is such as to conform with the turn in the handle ll.

Within an end of the lever 2| is a curved tongue 23 for engaging an end of a coiled contraction spring 24. The opposite end of the spring 2% is engaged by the tongue M in one of the socket members l2. Both ends of the spring 2 3 are turnedinwardly so that there will be no sharp corners or ends to which clothing or other objects may catch to be torn or otherwise injured. It will be noted that the ends of the tongues M and 23 are disposed inwardly for the same reasons as are the ends of the spring 24. There are no sharp projecting portions extending outwardly from the means for attaching the socket to the handle H.

The salient advantage of the slots l5 and the prongs 6 for attaching the socket to the mop handle lies in the fact that the prongs are integral with the socket, and that there can never be developed a loosened condition between the prongs and the socket as is the case when there is a rivet or other fastening means as in the conventional socket for holding a tool to a handle.

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

1. In a mop, having a stick, and a spring coiled thereabout, a cross head of sheet material having opposed complemental sections forming a socket to'secure said head upon said stick, one

of said socket forming sections having a plurality of piercing tangs therein, and the other of said sections having slots and a spring holding tang therein, the tangs on the first named section being inserted through said slots to lock the sections one to another and penetrating said stick to secure sai-d socket thereon, and the tang on said second mentioned section providing means for anchoring said spring to said socket.

2. In a mop having a handle, a bail, and a spring, a head formed of a single sheet of metal bent in the center to form a trough for said bail, side pieces extending from said trough, complemental socket portions on said side pieces, one of said portions having handle penetrating tangs at the sides thereof, and the other of said portions having slots registering with said tangs and through which said tangs extend to penetrate said handle, and a spring holding tang at the top of one of said portions and bent around a section of said spring.

3. A mop head in combination with a handle, a bail, and a spring, and comprising a single sheet of metal bent in the center to form a bail trough, and having complemental handle socket portions removed from said trough, one of said portions having handle piercing tangs, and the other of said portions having slots registering with said tangs and through which said tangs extend to pierce said handle, and a spring holding tang bent around a section of said spring.

4. In a mop, having a stick, a cross-head of sheet material having opposed complemental sections forming a socket to secure said head upon said stick, one ofsaid socket-forming sections having a plurality of piercing tangs ther in, and the other of said sections having slots, the tangs on the first named section being inserted through said slots to lock the sectionsone to another and penetrating said stick to secure said socket thereon.

5. A mop head in combination with a handle, and a bail, and comprising a single sheet of metal bent in the center to form a bail trough, and having complemental handle socket portions removed from said trough, one of said portions having handle piercing tangs, and the other of said portions having slots registering with said tangs and through which said tangs extend to pierce said handle.
