Specification of Letters Patent.

Patented Sept. 23. 191 3.

Application filed May15,1912. Serial No. 697,488.

To all whom o may concern Be it known that l, JOHN MCC. Loon- HA'RT, a vcitizen of the United States, resid ing at Coraopolis, in the county of Alle-` State of Pennsylvania, have inv'ented certain new anduscful Improvemen'ts in Mops, of which the following is a .speciication My invention has for its object to proa mop comprising a clamp for the mop material, a handle, and a securing :ferrule or clamp, adapted for easy and quick cons nection and separation, and so designed as to effect economy in the cotton `strands or other material used.

The device is illustrated in the accom-- panying drawings, 1n which FigureA 1 is a view ot the complete 1nop,.

in elevation. Fig. 2 is an enlarged vertical sectional view through theiclamping ferrule, handle and clamp. Fig. 3 `is a cross section on the line 111.111. of Fig. 2. Fig. 4 is'an assembled perspective View showing the wire clamps. Fig. 5 is a view similar to Fig. 2 illustrating a modified construction. Fig. 6 is a vertical section of the fer-rule used in the construction of Fig. 5 at right angles thereto. Fig. 7 is a cross section on the line VII. VII. ot' Fig. 5.

The roperative or Working portion of the mop is the head2 consisting of an assen1- bled mass ot strands of loosely woven cotton or the like. They are collectively held .'at their middle portions in a closely clamped central head portion by a wire clamp, illustrated in detail in Fig. Il. Thus, the clamp is made of a st `and of wire having one or more `coils 8 normally spaced apart at il and having extended securing side pieces or horns 5, 5, for attachment. 'to the handle 6. In the construction shown in the Vprincipal figures `of' the drawing the horns 5 terminate ininwandly turned studs 7, 7, adapted to extend into receiving sockets 8 at opposite sides olf the handle. rlhe cotton strands are `passedA diametrically through the spaces 4 and the coils 3 are then ,closely drawn together and securedy by hold ing clips or catches 9. The horns 5 are bent outwardly at their middle portions as indicated at 10, in rounded `form, tor the purpose of making interlocking engagement with the ferrule 11. Said errule is tubular in orrnadapted to slidingly embrace the handle 6, and is preferably iared or langd at the bottom, as at l2, forming a broad solid bearing against tla` assembled strands at the middle of the mop head. The ferrule is grooved longitudinally along each opposite inner side, as at 1?). to receive the h orns 5, and is also apcrturcd through the sides. as at 14, for clearance of the outwardly bowed projections 10. In connect- ,ing the parts together, the horns 5 of the mop head are tirst passed over the end of the handle (l and the studs 7 are inserted in sockets 8. The fcrrule 11 is then lowered over the horns, embracing them at each side by grooves 13, su'tlicient iorce being exerted to force the bowed projections 10 inwardly until they spring out through apertures 14. These apertures are so located as toregister with the projections when the flange 12 is pressed tightly against the mop head, and by springing out through the apertures the projections act as keys to securely lock the ferrule in position on the handle, in connection with the insertion of the studs 7 in openings S. It will be understood that the mop as thus constructed is ready for use. \fVhcn the head 2 is worn out, it is removed by merely vforcing the ferrllle back, and replacing a new head and clamp and connecting it with thc handle by the ferrule in the manner described.

lu the construction shown in Figs. 5, G, and 7 the head and clamps are substantially Kthe saine in construction except tbatthe horns 5 are straight and terminate in hooks 7 turned in reverse directions. 'lhe ferrule 11 is continuous without apertures at the side. but having continuous oppositcly lo` cated longitudinal grooves 13', while the interior cavity is partly closed at the bottom b v a flange l5 `at a slight distance above the edge cf the outer flaring flange 12. The handle (3 is provided with oppositely located pins 1G, 16, and between the inner end of the handle and flange 15 is inserted a coiled spring 17. 'lhe parts being assembled` handle t3 is `forced inwardly against `the spring 17 suilieient to lower plus 1G bellow the hooks 7` and the handle is then turned in tlie'manner of making a bayonet joint and allowed to recede under spring pressure, thus snugly sealing the pins against the hooks 7', as indicated in dotted lilies in Fig. t3.

It will be iniderstood that cach head and its wireclamp is complete as a unit and used with new strands,

strands,

may be collectively discarded when the mop head is Worn out, or the clamp be again if preferred.

'An especial advantage of thef clamp construction is its great simplicity 'and ystrength and economy of cotton strands. Thus the by being merely laid straightacross between the spirals 3, are of the shortest possible length, utilizing the smallest possible part of the middle for attachment, and effecting a great savingk in material. The clamping connection is very tight-and eiicient, The holding action of the ferrule is continuously maintained. The parts are rigidly held in position, and the device as a whole is very etlicient for the objects in view.

It will be understood that the invention may be changed orv varied in diierent detailsor proportions by the skilled mechanic,

but all such changes are contemplated as within the scope of the following claims. What l claim is:

1. A mop head consisting of a securing clamp formed of a continuous wire having its endmost portion composed of a plurality Lor/asia of overlapping spirally arranged coils and bent outwardly therefrom to provide extended handle portions, an assemblage 02|? mop strands fixedly embraced by said coils, and means holding said coils tightly together and in lembracing engagement with thel mop strands, subst tially as set forth.

2. A mop head consi ting of a series ofv strands and a securing clamp having a mfiddle spirally arranged portion engaging the strands, securing clips holding the spiral portion in tight engagement with the strands, and extended securing horns, sub- JOHN Moo. Lo'cKHAnT.
