In the form shown in the drawing, the mop This invention relates particularly to the head structure of mops of- absorbent material and to mechanism incorporated in the structure of the mop head whereby liquids can be squeezed from head Vl-is a rectangular block having an velon the mopping material without the necessity of gatedhandle 2 connected thereto in suitable dis position for iioor mopping operations.

The main objects of this invention are to provide a simple, inexpensive and improved form 3 of absorbent material is attached to the mop head I. As shown this‘material may be a mass of depending strands sewed to a sheet 4 of cloth> or the like which embraces the mop head I and of self-wringing moo; to provide a device of this kind having- in addition to the usual handle an is securely fastened by lacing 5. A second block 6 approximating in size the block I is attached to the block I by means of auxiliary handle by the manipulation of which the mop material may be eiiiciently squeezed; to provide a structure of this kind 'wherein the squeezing mechanism is held out of the way dur ing normal mopping operations; to _provide a mop structureÍ of this kind wherein the movement a pair of flat lever arms 'I which are securely fastened to the ends of the block 6 and extend approximately at right-angles to the main plane of that block. The arms 1 are each provided with a pair of pivot apertures 8 and 9 spaced apart along the lever arm ‘I and since the bracket sorbent body of mopping material into a com pact mass for expressing liquid therefrom 4by a 20 members which embody the lever arms 'I are ex of the squeezing member will gather up the ab- ` actly alike, the pivot apertures 8 of the two levers simple but powerful squeezing operation; and to will be in axial alinement, as will be apertures 9. provide a mop structure of this kind wherein the ‘Trunnions are mounted on the opposite ends leverage of the squeezing mechanism may be of the block I in axial alinement with each other readily adjusted. to vary the squeezing pressure or accommodate a difference in the thickness of 25 for connection with the lever arms ‘I and com prise studs I 0 whose sectional contour is that mopping material, due to wear or substitution of a segment of a circle of a diameter to fit the thereof. f pivot apertures 8 and 9 but flattened at opposite A speciñc embodiment of this invention is> sides to reduce one diameter thereof to a width shown in the accompanying drawing in which: Figure 1 is a perspective view of a simple form 30 »corresponding to a narrow slot I I which connects the apertures 8 and 9. The stud I 0 is provided of mop structure according to this invention. with a central aperture I2 to receive the attach Fig. 2 is an elevation of the same as viewed ing screw I 3 and with prongs I4 which are driven from one end of the mop head with the presser into the body of block I to prevent the trunnion member in its elevated or retracted position. Fig, 3 is a similar elevation showing the co 35 stud from rotating. Thus the flat surfaces of the studs at opposite ends of the head I will operative relation of the` mop head and presser always remain in proper relation to permit of adjusting the trunnions I0 from one pivot aper ture to another. These trunnionñats are pref member in the mop-squeezing position. Fig. 4 is a similar view with the lever arms of the presser member adjusted to a different posi tion for accommodatingr a thicker mass of ab 40 erably disposed in planes approximately parallel to the plane of the bottom of the head I so that the adjustment of the leverage of the arms 1 can be effected only when the squeezing mem on the line 5-5 of Fig. 2 through the trunnion ber 6 is in an intermediate position between its connection between the mop head and presser 45 operation position, shown in Figs. 3 and 4, and member. its retracted position shown in Fig. 2. A washer Fig. 6 is a similar sectional detail taken on I5 which is preferably integral with the stud I0, the line 6--6 of Fig. 5. overlays the margins of the pivot apertures 8 and Fig. 7 is an enlarged perspective view illus-` 9 and slot I I and coniines the lever arms to their trating the manner in which the trunnion stud is flattened in cross section to permit the shift 50 proper relation to the studs I D. The presser block 8 is provided with a short ing of the presser lever arms from one pivotal auxiliary handle I5 whereby it is swung on its aperture to another to adjust the leverage or” pivotal connection with the head I and it is also those arms. provided with a spring clip I'I positioned for Fig. 8 illustrates `the relation of the ñattened latching engagement with the handle 2 t0 hold trunnion with respect to one of the pivot aper sorbent material.

Preferably in a mop of this kind, the strands of material 3 which are at the right in Fig. 2 are made longer than those at the left side so that the mop material is effectively gathered up for pressure between the two heads as shown in Figs. 3 and 4. With the studs disposed as shown, the adjustment of the presser from one pivotal aXis to another, can be readily accomplished when the block 6 is at the midpoint of its arc of movement, by a simple movement in a radial direction. Although but one specific embodiment is here in shown and described, it will be understood that details of the structure shown may be altered 25 or omitted without departing from the spirit of A the invention as defined by the following claim. I claim: A mop comprising a head member having a handle, a body of absorbent material depend ingly attached to said head member, a presser member having a pressing face for squeezing the absorbent material against'l said head, a pair of longitudinally disposed and axially alined trun nions projecting from opposite ends of said head member, parallel lever arms rigidly attached to opposite ends of said presser member, being dis posed transversely to the pressing face thereof and having spaced bearing apertures to rotatably engage said trunnions at selective distances from said pressing face, and a handle on said presser member, said trunnions having circular cross sec tional contours correspondingly flattened at op posite sides in substantially parallel relation to said pressing face, and said lever arms each hav ing a contracted slot connecting its said bearing apertures and proportioned to permit the passage of the respective trunnion from one bearing aper ture- to another only when said slot registers with the ñattened sides of said trunnions.
