Application March 29, 1944, Serial No. 528,592 2 Claims. (Cl. 15-220) 1 2 The invention relates to window cleaners, and controlled by a lever l5, here shown as of channel has for one of its objects to provide a device of cross section (see Fig. 3) to embrace the arm H this character which will be simple in construc on which it is pivotally mounted as at It. The said lever is formed at its top with a grip portion tion, comparatively inexpensive to manufacture, l1 and at its lower end with angularly disposed and more e?icient in use than those which have been heretofore proposed. extensions l8 which carry a pin l9 which rides More particularly, the cleaner is of the type in slots 20 provided in ears 2| of a bracket 22 wherein opposed complemental cleaning elements rigidly carried by the arm Ill. As indicated in are adapted to operate simultaneously upon op Fig. 1, by moving the lever [5 on its pivot l6 to posite surfaces of a window pane, and a further 10 and from the broken line position shown in said ?gure, the arm [0 may be correspondingly swung object of the invention is to provide a construc tion whereby cleaning of the perimetric portions from and toward the arm ll. of the pane, where it meets and is supported by At their upper ends the arms l0 and H are formed for readily detachable connection either the sash members, may be insured. A still further object of the invention is to 15 to extension members 25 or directly to the clean provide a manually operable window cleaning de ing heads 26. The detachable connections here vice of the class described the operation of which shown are more or less conventional, comprising will be less fatiguing upon the operator than socket members 21 carried by the extension mem bers 25, and similar sockets 28 carried by the that of similar prior devices. With the above and other objects in view, which 20 heads 26, either of which sets of sockets may slid ably receive and frictionally engage the upper will appear as the description proceeds, the in ends of the arms Ill and II. Thus, for larger vention resides in the novel details of construc windows the extension members 25 may be in tion, and novel combinations of parts, more fully terposed between the arms H), II and the clean hereinafter disclosed and particularly pointed out ing heads 26, while for smaller windows the said in the appended claims. Referring to the accompanying drawing form extension pieces may be removed and the heads ing a part of this speci?cation, in which like 26 mounted directly on the ends of the said arms. The cleaning heads are duplicates, each com reference characters designate like parts through prising a spindle 30 extending upwardly from the out the views: connecting member 28 and having a block_like Figure 1 is a side elevational view of a typical member 3| rotatably and slidably mounted upon embodiment of the invention, illustrating it in it, to the opposite side faces of which block the operative position in relation to a window pane; cleaning elements 32 are readily detachably se Fig. 2 is an elevational view of the device as cured. One of the said cleaning elements may 2’ seen from the right of Fig. 1, the view being partly be a sponge 34, while the other element prefer in section upon approximately the plane indi ably comprises a pad of felt, napped or hooked cated by the line 2—2 of Fig. 1; Fig. 3 is an enlarged horizontal sectional view, fabric, or the like. The said sponges and pads may be alternatively positioned to engage the sur on the plane indicated by the line 3-3 of Fig. 1, faces of a window pane 36 by turning the block looking down; Fig. 4 is a perspective view of one of the block 40 3| on the spindle 30 to bring the desired element like members which mount the cleaning ele adjacent the pane, as will be readily understood. The block may be retained in position to present ments; and Fig. 5 is a rear elevational view of one of the either element to the pane by a suitable detent, cleaning elements. such for example as a pin 31 carried by the As will be understood from the said drawing, 45 spindle 30 and engageable in a groove or recess the device comprises a U-shaped frame adapted 38 formed in the adjacent face of the block. A to straddle a sash and pane from either the top spring 39 interposed between the opposite face or the bottom, which frame includes a pair vof of the block and a nut 40 threaded on the spindle spaced parallel arms I0 and H, the latter of yieldingly maintains engagement between the pin which is substantially L-shaped with its short leg 50 and groove. l2 being provided with a hinge connection l3 by As here shown, the means for readily detach ably mounting the cleaning elements 32 on the means of which the lower end of the arm I0 is . pivotally connected thereto for swinging move block member 3| comprise keys 4| carried by and projecting from the opposite side faces of the ments of said arm toward and from the com panion arm H. Such movements are effected or 65 said block, and slots 42 formed in the rear plates 2,413,854 33 of the cleaning elements. As will be readily understood, in assembly the heads of the keys 4| 4 elements 32 are then turned through an angle of 90° to position the slots crosswise of the key heads. the bolt of which is adapted to engage a serrated lug 5| carried by the frame arm I l and project ing through an opening 52 in the said lever.
