1 Be it known that I, THOMAS L. BONSALL,

a subject o'fthe King of Great Britain, and

which the clothis securely held but from' which it may be readily removed without 1 the use of tools. 3

. Astill further object is toprovide a mop r in which the'cloth is normally held: in tension in a zframe, the frame being readily adjustable to slacken the cloth for wringing and adjustable'with equal readiness to again tion to hold the cloth intension, which :tension the -cloth..

The device consists briefly of a pair of overlapping frame members .hingedly con- 1 :nected'to one another and to aihandle socket, said members being arranged to form a toggle between the ends of which the mop cloth is connected. The two members are provided withmeans for latching them in posimeans must be manually operated to slacken the cloth but will be automatically operated by the use of the. mop. to tension the cloth and latch the frame to hold the cloth in 1v tensionvention In the drawings which illustrate the in- Figure 1 is a side view of the device in operative position, the mop .cloth being illustrated diagrammatically. 'Fig' 2 is a side elevation of. the device 'unlatched toslacken the cloth for wringing.

f Fig. is a plan View.

'Referringmore particularly to the drawings, 11 and l2designate as a whole a pair Jof members hingedly connected in overlapping relation by a pin 13. The remote ends ofthe members'are provided withhooklikeportions 14, the openings'15 of which are at the tops of the portions and directed J toward the hinge pin 13, as clearly shown.

A mop'cloth 16, which is. diagrammatically illustrated, is provided having at the ends enlarged portions 17 adapted tobe slipped Specification of letters Patent.

in the edgewise direction of the cloth into the hooks 14: and tobe therein retainedby reason of the enlarged portions 17 being unable to pass through the openings 15 of the hooks. As clearly shown, the cloth passes from the openings of the tops and remote portions of the hooks to the under side, the cloth being stretched between the hooks .at opposite ends of the frame. As will clearly be seen in-Fig. 1, the

hooks over the members 11 and 12 are slightly out of alinement when the cloth is stretched tightly so that the frame constitutes a toggle and .downward pressure on its hinge pin 13 will tend to 'move the hook ends apart and increase the-tension of the mop. A handle socket 18 is mounted on the pin 13 and is thereby hingedly related to the frame.

The form of frame illustrated is composed entirely of heavy wire, but it will be understood fthat the frame may be constructed of other material without departing in any way from the spirit of the invention, although external appearance of the frame may be slightly'altered as a result of the different method of manufacture.

Each of the members 11 and 12 comprises a transverse central portion 19' turned at its ends away from the hinge pin and bent approximately in a circular curve in vertical planes to form the hooks 1 1. From what may be termed the inner ends of the hooks,

transverse members 20 extend a short distance toward the longitudinal axis of the frame. At the inner ends of these portions 20 the material is turned at right angles into two substantially parallel, spaced portions 21, which are looped in any suitable manner at 22 'to receive the hinge pin and then. continuedfor a short distance beyond thev pin in parallelism with the portions 21 of the other member, such continuing portions being designated 23. The portions 21 of either member may be outside the corresponding portions of the other member and, as illustrated, the'portions 21 of member 11 lie outside the portions 21- of member 12. The extremities of the outermost parts 23 are turned inwardly as at 24, so as to cross over the portions 21 lying inside them and may be turned slightly downwardly, the purpose being merely to provide rests to support the extremities of one member on the other. The extremities of the inner parts 23 are turned upwardly and then downwardly in substantially parallel planes to form loops 25 projecting upwardly above the plane of the members 11 and '12. The extremities 26 of the material beyond the loops pass under the portions 23 and are turned out wardly and slightly upwardly to form shal- -lo'w hooks engageable under the portions21 of'the other member. The lower surface of the hooks may be beveled as at 27 so that the hooks-26 may be forced'past the other member, the material :between the loops V and theihooks 14 yielding to permit passage of the hooks'and then returning to original positions to hold the :hooks in engagement 15 undertheothermember, Y

Thefhandle socket "may be conveniently r formed of a piece Vofsheet metal. -This metal is loopedin-its centralpart around'the pin 13, asishown1at28, Fig. 2, and the. two end' portions @are 1 stamped or upset to form semi-circular portions 29 which unite to form the handle receiving socket. Each of the portions is provided :at opposite sides eachpair ispro'videdcwith' one or more lugs radapted'ltobe turnedoVerFthe other flange of the; pairv to connect the i'fianges and hold the socketin handle retaining form. Oh-
