MOP-HEAD.

Specification of Letters Patent.

Patented Dec. 31, 1907.

. To all whom 'it may concern:

Be it known that I, HAROLD M. STUReEoN, a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented certain new and useful Improvements in Mop-Heads; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompany,

ingdrawings, and to the letters of reference marked thereon, forming part of this specification.

My invention relates to the construction of mop-heads, and the object of my improvement is to simplify the construction of mopheads and render them more effective in operation.

My improvement is illustrated in the accompanymg drawings in which:

Figure 1 is a top or plan view of a mophead embodying my invention. Fig. 2 is a side view of the same with the lever thrown forward. Fi 3 is a cross section of the same on the Tine acx in Fig. 1. Fig. 4 is a perspective view of the spring of my improved mop-head spring showing the studring upon the upper end thereof. 1

The drawings show a mop-head, the general features of which are of similar construction. It consists of a head A provided with a central sleeve or socket A which receives and is secured to the end of a handle D. The head A is provided with a groove a which extends along its outer face and across the ends a thereof to receive a wire yoke C. The handle D is reduced in size from the end of the sleeve A for sufficient distance to receive a spiral spring E having a ring E formed on its upper end, which spring extends from the sleeve A to the ring E on its u per end, and when relaxed forces said ring E against the shoulder (1 formed by the enlarged portion of the handle D, as illustrated in Fig. 2.

Upon the upper end of the-spring E, I form a ring E by winding the coils of wire snugly together so that there is absolutely no torsion or sprin therein at that point. This ring E may lie formed of as many coils of wire as may be desired,but I preferably use three coils. On opposite sides of the ring E I form studs e 6, preferably by making short outwardly projecting return bends in one of the coils of wire forming said ring E. These studs 6 e may however be formed in any way desired, but I prefer to use the construction herein shown.

After the ring E and studs 6 e thereon have been formed as described, I preferably treat the spring E and ring E and studs 0 e to a tin bath whereby the several coils of the spring E become securely soldered and oined together at 0 so that they form one integral ring with oppositely projecting studs 6 e thereon. I may, however, use the spring E With its ring E and studs 6 6 Without tinning the same with good results, but I prefer to tin the sprin with its ring as it not only joins the severa coils of the ring E securely together, but also preserves the spring and ring from rust. The great advantage of a spring having a stud-ring upon its upper end integral therewith is its cheapness of construction, the facility with which the same may be assembled with the other parts of the mop-head, and also that a stud-ring so conconstructed upon the upper end of a spring is better adapted to exert a straight line pressure from both studs e 6 upon the spring E.

The arms 0 C of the yoke C are bent inward so as to engage and be pivoted in the holes f in the lever F. This lever F is made of the usual semi-circular form in cross section, so that it fits down over the handle D, and when in this position the holes f therein engaging the studs e e on the ring E of the spring E are on the plane of the center of the handle D, which insures the lever remaining in a locked position until released by the operator.

I am aware that mop-head levers substantially like the lever F have been pivoted on studs on a cast ring resting against the upper end of the spring, and that mop-head evers have been pivoted to one of the coils of the spring itself; but I am not aware that a ring as ever been formed of the coils of the wire wound closely together integral with the spring itself and having studs formed thereon as I have herein shown and described.

Therefore having described my invention so as 'to enable others to construct and use pressed loops projectin from one of the coils the same What I claim as new desire to secure of said ring, substantial y as set forth. 10 by Letters-Patent of the United States is: In testimony whereof I affix my signa- In a spiral mop-spring, a spirally Wound ture, in presence of two Witnesses. 5 spring, an integral ring on one end thereof HAROLD M.
