MOPHEAD FASTENER Filed Dec. 15, 1954 Patented Mar. '3, 1936 4 Claims.

This invention aims to provide a simple means for gripping the head of a mop, and holding the head of the mop together, without stitching, the device being capable of ready assembly with, and ready removal from, mop holders of standard and approved constructions.

It is within the province of the disclosure to improve generally, and to enhance the utility of, devices of that type, to which the invention appertains.

The drawing shows, and this specification describes, a satisfactory material embodiment of the invention, but it is to be understood that a mechanic, working within the scope of what is claimed, may make such changes as his skill may dictate, without departing in corresponding measure from the spirit of the invention.

The reader is requested to consider the following specification in connection with the drawing, wherein:

Fig. l is an elevation showing a mop holder wherein the claimed device is embodied;

Fig. 2 is a fragmental elevation, with parts broken away and parts in section;

Fig. 3 is a top plan of the clamp, with the mop head broken away;

Fig. 4 is a section on the line 5-4 of Fig. 2;

Fig. 5 is a side elevation showing the jaws, in the position which they will assume prior to assembly with the mop head.

The device forming the subject matter of this application embodies a clamp, made up of two trough-shaped metal jaws I, which are of identical construction, it being unnecessary, therefore, to form two jaws which are difierent, a single form of jaw being suflicient, and the cost of manufacture being reduced accordingly.

The convexed sides 2 of the jaws I are disposed toward each other. From each jaw I, a bendable prong 3 is struck. Each jaw I has an opening 4. The prong 3 and the opening 1 are spaced apart, lengthwise of the jaws I, and are located at equal distances from the ends of the jaws, so that, when the jaws are turned end for end, as shown in the drawing, the prong will be in a position to pass through the hole 4 of the other Jaw.

Each jaw I has a bendable tongue 5 at one end, and when the jaws are reversed, end for end, as aforesaid, one tongue 5 is disposed at each end of the clamp. The tongue 5 of each jaw is bent into U-shape, to engage in the concavity 6 of the, other jaw, at the end thereof.

The prong 3 of each jaw I is extended through the opening 4 of the other jaw, and is bent to trough-shaped jaws, with 0 thickness or strength so that they are rigid and substantial. Not only do the jaws I grip the mop head under pressure, but, as well, there is provided a positive means for preventing the mop head from slipping lengthwise of the jaws. That 15 means embodies the rivet I6 and the prongs 3, which pass through the mop head, together with the tongues 5, which close the clamp at its ends.

The jaws I hold the mop head securely against slipping in any direction, stitching generally required to keep the yarn of the mop head I together. Because the mop head I is not stitched or fastened together otherwise, the head can be opened out readily, when not in use, and will dry more when the head is stitched together into a more or less compact body. Since the mop head I can be dried thoroughly, it will last a long time.

The device can be used in any standard mop holder, such as the holder H, wherein the handle 30 8 is secured to one end of a loop-shaped frame 9, including side bars I0 and a foot piece II. A slide I2 is mounted to reciprocate for adjustment on the side bars I0, and is under the control of an operating and pressure member, such as a 35 screw I 4, threaded into the base of the frame 9. The clamp that holds the mop head I is bound between the foot piece II and the end I5 of the slide I2, the concavity 6 of one jaw receiving the foot piece II closely, and the concavity of the 40 other jaw receiving the end I5 of the slide.

It is probably unnecessary to point out that the device for gripping the mop head I is strong, inexpensive to manufacture, easily assembled with a holder, such as the holder H, and easily 45 removed from the holder.

Having thus described the invention, what is claimed is:

1. A mop head clamp made up of two like,

disposed toward each other, each jaw having a bendable prong struck from it, and each jaw having an opening, the prong and the opening being spaced apart lengthwise of the jaws, and

being located at equal distances from the ends and do away with the 20 quickly than is the case 25 their convexed sides 50 of the jaws, each jaw having a bendable tongue at one end, the jaws being reversed, end for end, to arrange one tongue at each end of the clamp, the tongue of each jaw being disposed in U-shape, to engage in the concavity of the other jaw, at the end thereof, the prong of each jaw being extended through the opening of the other jaw and being engaged with said other jaw, in the concavity thereof.

2. The mop head clamp of claim 1, wherein the jaws are connected, additionally to the prongs, by a securing device disposed between the prongs.

3. A mop head clamp made up of two like, trough-shaped jaws, with their convexed sides disposed toward each other, each jaw having a bendable tongue at one end, the jaws being reversed, end for end, to arrange one tongue at each end of the clamp, the tongue of each jaw being disposed in U-shape, to engage in the concavity of the other jaw, at the end thereof.

4. In a device of the class described, a mop comprising a frame including a foot piece, a slide mounted to move on the frame, toward and away from the foot piece, means for moving the slide toward the foot piece in clamping relation thereto, a mop head, trough-shaped members having their convexed portions disposed toward the mop head, the trough-shaped members being located on opposite sides of the mop head, and means for holding the trough-shaped members together, to cause them to bind upon the mop head, the concavity of one of the trough-shaped members being shaped throughout its length to receive the slide, and the concavity of the other of the trough-shaped members being shaped throughout its length to receive the foot piece.
