UNITED STATES PATENT OFFICE.

FREDERIC ALLEN, OF WORCESTER, MASSACHUSETTS.

MOP-HEAD.

Specicaton of Letters Patent No. 16,137, dated December 2, 1856.

il 1o all whom it may concern.'

Be it known that I, FREDERIC ALLEN, of Worcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Improvement in Mop-Heads, which I do hereby declare is fully described and represented in the following specification and the accompanying drawings, of which- Figure l, is a side view, and Fig. 2, an edge elevation of the said article.

In carrying out or constructing my invention I take a tapering bar A, of spring steel, and bend it at the middle, and from thence to one end and at such end as shown ata, b, c, in Fig. l. It thus has three bends or flexures the latter or that shown at 0, being so as to form an eye CZ, for the reception of a link e, which has the bar inserted through it previously to the formation of the eye. The other end of the bar A, I bend down so as to form a flat hook f, to hold the link in place when the hook or end of the bar A, is extended through it, as shown in dotted lines in Fig. l. The bar A, should be provided with a shank g, for connecting it with a mop handle B.

In applying` the mop cloth to the aforesaid head it should be placed on it while the link e, is off the hook f. This having been accomplished the head is to be compressed on the cloth and the link slipped on t-he hook. By this process the flexure ZJ, of the spring will be not only operated so as to confine the cloth in place, but it will give way in accordance with the thickness of the cloth and adapt itself to the same. The said flexure thus renders the mop head self adjusting and applicable to receive either a thick or thin cloth. This fixture is not found in the common bar clamp mop head operated by a screw. In my improved mop head the link is always in one position when the clamp contains a cloth, whatever may be the thickness of the cloth. No setting up of a screw is required to x the cloth to the head. Such being done by the self adapting spring flexure Z), and the link while being bent down toward and conformed to the remainder of the mop head.

My improved mop head though simple in its construction is very advantageous in operation.

I do not claim a clamp formed of two bars hinged together at one end of each and provided at their opposite ends with a screw for forcing one of them toward the other, but

Vhat I do claim is- IIy improved spring clamp mop head as made of a bar of spring steel as stated bentand formed with an eye and a hook at its opposite ends as explained and having a link applied thereto so as to operate therewith as specified.

In testimony whereof I have hereunto set my signature this day of August 1856.

Vitnesses DANIEL A. HAWKINS, J r., EDWARD H. BieELow.
