In Ger-ma 3 Claims. This invention relates to cleaning devices for floors, windows, walls and the like embodying a carrier for a moisture absorbing cleansing element of sponge like material, such as a pad. of sponge rubber, the carrier having a manipulating handle connected thereto, and a handle carrying a presser plate detachably connected to the carrier for the moisture absorbing cleansing'element and operative to position the presser plate into engagement with the moisture absorbing cleansing element in opposed relation to its carrier and by pressure applied to the handles squeeze the cleansing element between its carrier and the. presser plate to expel moisture from the cleansing element.

In cleaning. devices of this character heretofore the manipulating handle has been secured in fixed angular relation to the carrier for the cleansing element. In the use of the cleanin device with the manipulating handle so connected to the'carrier for the cleansing element it is impossible to move the cleaning device below articles of furniture which are in close proximity to the floor with the result that the furniture may be easily damaged by the manipulating handle striking against the same. In other instances the presser plate carrying handle has been permanently pivotally mounted at the upper or lower side of the manipulating handle to have oscillatory movement to position the presser plate into engagement with and squeeze the cleansing element between its carrier and the presser plate to expel moisture from the cleansing element,

with the result that the cleaning device is not "only cumbersome in use, but the presser plate carrying means will serve as an obstruction to a greater extent than when the manipulating handle is fixed in angular relation to the carrier for the cleansing element to prevent passing the cleaning device beneath articles ofiurnit'ure in the use of the cleaning device.

It is the object of the invention to provide an improved construction and'arrangement of cleaning device of this character to overcome the disadvantages above set forth,- and to provide a cleaning device that is simple in structure highly emcient in use.

An embodiment of the invention isiIIustrated in the accompanying drawing-in which Figure 1 is an elevational vice embodying the invention. and showing the same in a position of'use. f v

Figure 2 is an elevational view of the presser plate-carrying handle, and Figure 3 is a plan view ofthe cleaning device and presser plate carrying handle connected thereto, andshowing the cleaning. device and in position prior to ad- 'iusting the same to position the presser plate into engagement with the cleansing element in opposed relation to the carrier therefor.

In me embodiment of the invention illustrated view oi'a cleaning'de in the drawing there'is provided a manipulating handle a secured at one end in a sleeve portion at one end of a member b to carry the handle, said member being provided with a bifurcation b at the opposite end whereby it is pivotally connected to a plate d by a pin 0, the plate it being secured in edgewise relation to the back of a body or carrier for a moisture absorbing cleansing element, said carrier being shown in the form of a plate e-with the plate d extending transversely of the plate e midway its ends. 0n the front or face of the plate e opposite the plate it there is attached by suitable means a facing of moisture absorbing cleansing material, shown in the form of a pad 1, such as sponge rubber. The carrier or body e may be provided with openings or apertures to, reduce the weight thereof, as indicated at e in Figure 3. In the preferred form of the means to attach the pad 1 to the plate e there is provided on one face of the pad two pockets f, one adiacent each end of the pad, formed of flat pressed tubing of elastic material, such as rubber. The pockets may be open at both ends, or if desired only at the ends opposed to each other, to permit of engagement therein of the plate e.

To mount the facing or pad 1 on the plate e one end of the plate e is engaged in one pocket I and then the other pocket is stretched sufllciently to engage it over the opposite 'end of the plate e. Due to the elasticity of thematerial of the pockets and of the facing or the pad ,fthis operation may be readily performed. The facing or pad f may consist of separate sections, each section being equal in size to one-half of the plate e, and in which case each section of the pad is provided with a pocket .1".

The plate d is provided with two recesses a, h in the edge thereof, the recess h extending approximately parallel to the back of the plate e and the recess a spaced therefrom and disposed at an angle of approximately 45 degrees to the back of the plate e. w

The sleeve b slidably carries a spring influenced detent in the form of a bolt i; which projects downwardly to such an extent under the action of the spring that the lower end thereof, dependenton the position of-the handle a, engages in one of the recesses g, h and thus holds the handle a in predetermined angular position relative to the plate e, and when the bolt engages in the recess h the handle will extend substantially parallel to the back of the cleaning device. The end of the plate (1 opposite the end arranged with the recesses o, h is constructed to form a hook opening rearwardly of the front edge of the plate b and forward side of the body e.

To expel moisture from the facing or pad I there is provided a presser plate '0, which may consist of sheet metal having a plurality of openings or apertures and slots therein (Figure 3) to reduce the weight of the plate and permit of I the passage of liquid squeezed from the cleansing element or pad-f. The presser plate 0 is pivotally supported intermediate its ends and arranged at one side, the lower side as viewed in Figures 2 and 3, of a flattened end portion of a member a the opposite end portion of which member is arranged as a sleeve for the engagement therein andcarrying of a handle m. To pivotally l pport the plate 0- it is provided witha pair of perforated spaced earsl midway its ends and arranged centrally of the side edges of the plate and between which ears the flattened end portion of the member z is engaged, and pivotally connected thereto by a pin a engaged in the ear perforations and a perforation in the flattened portion registering with the ear perforations, whereby the presser plate 0 is adapted to have movement on the longitudinal center of the plate and transversely of the handle m. The plate 0 is urged in a direction to engage the front marginal portion with the flattened portion of the member 2 forwardly of the pivotal connection of the plate 0 by a spring a: coiledabout the pivot pin 2' with one end of the spring engaging the plate 0 and the opposite end engaging the member z rearwardly of the pivot support of the plate 0. By the connection of the presser plate -0 with the handle member an the presser plate is adapted to be carried and manipulated by the handle, and, if desired the sleeve portion of the member z may be provided with a hook v that may be readily engaged upon a suitable support to support the device therefrom.

A bell-crank member constituting two like angle plates i one angle portion of which is of greater length than the other angle portion are secured together in spaced relation by a spacing member n,'the plates 1 being spaced apart a distance somewhat greater than the thickness of the plate 11. The bell crank member is connected at the end of the angle portion of greatest length to the free end of the flattened portion of the member 2 by a pin is, and the plates are connected together at the ends of the other angle portion by a pin p.

In use the manipulating handle a is locked in position to extend in angular or parallel relation to the plate e by the bolt engaging one of ,the

recesses o, h, and when the bolt is engaged in: the recess 9, as shown in Figure 1, is locked to to the water used, it is necessary that the water be frequently expelled from the pad, and also that the water be sufficiently expelled from the pad so that the water applied to the surface to be cleaned will be absorbed by the material of the pad from the cleaned surface.

To expel moisture, such as water, from the cleansing pad and thus cleaning the pad, the expelling means is pivotally connected to the body e of the cleaning device -by engaging the hook y of thefplate d between the plates 7 of the bell crank member so that the pin p will straddle the book 1 as'indicated in dot and dash lines in Figure 1, with the bell crank member extending transversely of thefront edge of the body e and positioning the presser plate carrying handle at as indicated at A in dot and dash lines in Figure 1. After the presser means has been so connected to the body a of the cleaning device the handle m is moved to position to extend substantially in the plane of and-diverting from the manipulating handle a and with the presser plate 0 engaging the pad in opposed relation to the plate 8, as shown in dot and dash lines- B in said handle m to move to the position indicated by dot and dash lines C to extend adjacent and approximately parallel to the manipulating handle a the force on the handles exerting a strong pressure on the pressure plate 0 and the pad carrier e' andthereby compressing the'pad f and the expelling of the water therefrom, it being possible to compress the pad sufficiently to expel practically all of the water from the pad.

By repeated-immersion of. the cleaning device in clean water and repeated compression of the pad foreign substances will be freed and expelled from the pad; The pad may be compressed to such an extent that practically all of the water will be expelled therefrom and leave the pad sub stantially dry, so that after removal of the presser means from the cleaning device the surface under treatment may be polished in a dry state by the cleaning device.
