IMPROVEMENT IN MOP-HEADS.

Specification forming part of Letters Patent No. 88,917, dated April 13, 1869; reissue No. 7,398, dated November 21, 1876; application filed September '26, 1876.

To all whom it may concern:

- Be it known that we, EMILE SIRRET and EMILE GEORGE SIERET, both of Buffalo, in the county of Erie and State of New York, have invented a new and useful Improvement in Mop-Heads, which improvement is fully set forth in the following specification, reference being bad to the'accompanying drawing, in which Figure 1 represents a face view or elevation of our mop-head. Fig. 2 is the binder-frame of the mop-head, in which is shown the manner of introducing the cross-head and bridle into the frame. Fig. 3 shows the cross-head and bridle detached. Fig. 4 is a section in the line a; m of Fig. 1.

Similar letters indicate corresponding parts.

This invention consists in a mop-head consisting of an open stationary frame, forming a. part of the threaded socket which receives .he handle, in combination with the movable aw or cross-head, and a ring-nut arranged on he screw-socket, for operating the movable aw, as will be hereinafter described.

We construct our mop-head in any of the hapes known with screw and thumb-nut, as sed in many of the iron mop-heads; but in rder to obviate the inconvenience of wireinding, boring, and riveting, in making the '.nder, we cast the binder-frame or outerjaw id screw-threaded hollow shank B (with a 'cket or hole therein for the handle) whole in one piece, so that the binder-frame or vter jaw is rigidly connected with the screwank, and forms the fixed or stationary jaw the mop-head. A thumb-nut, L, is placed the screw-threaded shank B, and is arranged work loosely thereon. The nut, instead of -ving the hinder or outer jaw of the mop- 1d, and bringing it to press against the ss-head, as is commonly done on other p-heads, is arranged so as to have the conry action, the cross-head (shown detached Fig. 3) being operated by the thumb-nut king on the threaded shank B, and being le to press the mop against the outer part 'aw A, which is made with an open frame the purpose of receiving and holding therehe mop or mop fabric, the frame of said of the inner jaw J and connecting-bars E E, the jaw A and its frame being cast in one piece with the screw-threaded shank B, the jaw A being thus made stationary and rigid with the hollow screw-shank B. The crosshead is composed of a crossbar, 0, two arms, F F, which project from its lower side, and a bridle or collar, G, and is represented detached in Fig. 3. The ends of the cross-bar are notched, as at D, seen most clearly in Fig. 4, to allow the notched ends to fit and slide upon guides 0 formed on the inner edges of the end bars E of the stationary frame.

The mop-head is cast or made in three pieces, namely: the stationary binder-frame, comprising the outer jaw A, and the bars E E. and J, and threaded shank B, the cross-head comprising the cross-bar 0, arms F F, and bridle or collar G, and, lastly, the operating-nut L. The bridle or collar G, as here shown, is semicylindrical, and is arranged on the cross-head so as to move along that side of the screwshank which is opposite to the side along which the connecting-arms F F extend, whereby, in connection with the notched cross-bar which engages the guides O of the binderframe, the crosshead is prevented from becoming detached from the frame of the stationaryjaw A, and is only allowed to move toward and away from the jaw A under the operation of the thumb-nut. The bridle or collar G is provided with notched projections H H on its opposite sides, so arranged as to embrace a flange, I, on the outside of the nut L, and by that means the nut and bridle are connected to each other. We make the connecting-arms F F of such a length with reference to the length of the shank B, as to allow the bridle or collar G to swing over the end of the shank when the cross-bar O lies close to the bar J of the frame.

In order to place the cross-head in the frame (the handle K being out of the socket of the shank) the cross-bar O is inserted in the frame in the position shown in dotted lines in Fig. 2, so that its notched ends engage the guides 0 when the crossbar is brought close against the bar J, and the bridle or collar is swung or sprung over the end of the shank. The bri- :r jaw consisting, with the jaw proper, A,

die or collar G, whether it is semicircular or a completed circle, is so made and arranged that it will slide over the surface of the thread of the shank. When the bridle is semicircular it is so arranged on the arms F F that its place on the shank is on the side opposite to that along which the arms F extend. The cross-head, after being united to the binderframe in the manner described, is held united to it, as shown in Fig. 1, at one part by the guides O O, which enter the notches D D of the cross-bar, and at another by the arms F F and bridle or collar G. The bar J and shank B of the frame are between the arms F and bridle G, the arms F F moving over or past the bar J on one side of the axis of the shank while the bridle or collar Gr moves over or past the shank on the other side of its axis. The thumb-screw nut is caused to engage with the notched projections H of the bridle or collar by bringing the bridle even with the end of the shank, so that the projections will extend beyond the end of the shank, and enable the nut to be passed between them, its flange I entering the notches of the projections, as shown in Fig. 1. The handle is then run through the nut and shank, its end K extending past the bar J, so as to serve as a stop to prevent the nut from being unscrewed oflthe shank onto the handle, andalso to enable one to secure the handle by inserting a nailthrough the end K above the edge of the bar J, and thereby save the necessity of making a hole through the shank for that purpose.

What we claim as new, and desire to secure by Letters Patent, is

The open stationary frame, forming a part of the threaded socket which receives the handle, in combination with the movable jaw or cross-head and a ring-nut arranged on the screw-socket of the open stationary frame, for operating the movable jaw and adapting the latter to come in contact with the upper part of the open fixed frame, for clamping a mop, substantially as described.

In testimony that we claim the foregoing we havehereun-to set our hands and seals this 20th day of September, 1876.
