HMOP-HEAD.

SPECIFICATION forming part of Letters Patent'No. 550,449, dated November 26, 1895.

Application filed March'26, 1895. Serial No. 543,234. (No model.)

To all whom it may concern.-

Beit known that 1, AUGUST S. HELD, a citizen of the United States, residing at Freeport, in the county of Stephenson and State of Illinois, have invented certain new and useful Improvements in Mop-Heads, of which the following is a specification.

The object of the invention is to produce a mop-head that in simplicity, convenience, and durability shall be more satisfactory than those now commonly in use.

In the accompanying drawings, which fully illustrate the invention, Figure 1 is a side view of the improved devices. Fig. 2 is a similar view, the larger parts being in section and the cutting plane being axial and parallel to the plane of the paper in Fig. 1. 3 is a section at 3 3, Fig. 1; and Figs. at, 5, and 6 relate to modifications.

In Figs. 1,2, and 3, A represents a mop-handle bearing a mop-head body consisting of a socket B for the handle and a cross-bar B,

preferably having its lower side and its ends grooved in the usual manner. The handle may be secured in place by a staple 0. Below and alongside the cross-bar lies a bar E for clamping a mop against the cross-bar, and upon opposite sides of the handle are ways D, parallel to the latter and formed by internal grooves in the socket and by the handle itself, which closes the grooves laterally. In these ways are entered the ends of the rods E whose opposite'en'ds are connected to the corresponding ends of the bar E by arms E which lie in the end grooves of the cross-bar. For simplicity and economy the bar E, the arms E and the rods E may be formed, as shown, from a single piece of heavy springsteel wire suitably bent, though such integral formation is not indispensable. The rods are materially smaller than the channels in which they lie and hence may be inclined ith reference to such channels or ways to a degree depending upon the distance to which enter further into the ways unless the inclination be lessened; but the inclination causes little or no resistance to their sliding still fart-her out of the ways, and as they cannot move without a corresponding movement of the bar E it follows that the latter is free to move toward the cross-bar, but as it thus moves is always securely locked against the slightest return movement, for the rods are constantly and progressively pulled over and kept in bitin g position by the elastic force mentioned. Force acting downward upon the bar E enormously increases the binding or biting effect, and no matter how hard and smooth the rods and the ways may be the stronger the pull the more remote the possibility of slipping. If, however, the rods be swung by the hand into line with the ways, they, together with the arms and bar E, are readily moved down to the position shown in dotted lines in Fig. 1. A suitable mop being then placed between the bar and cross-bar, the whole is placed uponthe floor with the handle vertical, and by pressure downward upon the latter the mop is clamped with almost any desired force, and, as already explained, the clamp constantly looks itself against the least return or mop-releasing movement.

If desired, the rods E may be notched, as shown at E to engage the edge of the way- Walls.

To avoid direct contact of the lower ends of the rods with the handle, the way-grooves may be external, as shown at D,Fig. 4, a plate X being fixed above the grooves and provided with perforations X for the passage of the rods into the latter.

Figs. 5 and 6 are analogous to Figs. 2 and-3 and show a further modification of the form of Fig. 4. Here the internal walls of the grooves are notched or provided with a series of offsets D to receive the ends of the rods E as the latter rises out of the waysthat is, as more and more of the body of the rod appears above the way. The plate X is shown as provided with recesses K to receive lugs L upon the socket B and thus prevent relative rotation of the plate and socket.

WVhat Iclaim is 1. The combination with a mop head body having ways approximately parallel to the line of the handle and alongside the same, of a mop clamping bar lyingzbelow the head, rods normally inclined to the direction of the ways but having their ends entered therein, respectively, and arms joining the opposite ends of said rods, respectively, to the corresponding ends of said clamping bar, substantially as set forth.

2. The combination with the mop head body having alongside the handle ways approximately parallel to the same, of the normally inclined rods entered loosely in said ways, the mop-clamping rod below said body, and the inwardly bent arms integrally connecting the outer ends of the inclined rods to the corresponding ends of the mop-clamping rod, substantially as and for the purpose set forth.
