a J Wed/$33? W WINDOW-CLEAN IN G DEVICE.

Application med March 6, 191

To aZZ whom it may concern Be it. known that I, MATHEW BLACK, a citizen of the United Statesof America, residing at New York city, borough of Brooklyn, Kings county, State of New York, have invented certain new and useful Improvements in Window Cleaning Devices, of which the following is a full, clear, and eX- act description.

This invention relates to an improvement in window-cleaning devices, the object be ing to provide a device of this character that can be cheaply manufactured and sold and yet be efficient in operation. V

One of the chief features of my invention is that it can be passed through the space between the frames or sashes of windows when either is moved up or down to open the window.

A further feature of the invention is that my device is constructed to allow the clothcarrier to contact with the window pane without the applicationof force or pressure by the user of the device, as all the user of the device has to do is to move it up or down or sidewise between the opposing window-panes.

I willnow proceed to describe my invention in detail, the novel features of which I will point out in the appendedclaims, reference being had to the accompanying drawing, forming part hereof, wherein Figure 1 is a face view of one side of the cleaner, the handle being broken away; Fig. 2 is a similar view of the opposite face of the cleaner; Fig. 3 is an enlarged side view of the cleaner, showing in section a cleaning cloth secured thereto; Figs. 4 and 5 are face views of opposite sides of the cleaner showing the manner of holding a cloth; and Fig. 6 is a diagrammatic view, on a reduced scale, illustrating the manner of using the cleaner.

My improved window cleaning device consists of a handle 1 secured to which, and at one end thereof, are a plurality of

resilient arms

2 and 3. To the outer end of each arm is secured a plate 4 carrying a rail or rack 5 which assists in the mounting or holding of a cleaning cloth 6. To further assist in the holding of the cloth 6, I provide clamps or clips 7 and 8, each of which is (in this instance) secured to the handle 1. The clamps 7 and 8 are preferably pivotally secured to the handle 1 as at 9 in order that they can be swung outwardly to clear the frame of the cleaner, which I will designate Specification of Letters Patent.

some pressure clamping posi- As will be seen in Figs. 1 and 2, the clamp bears upon the arms 2and 3, at itsouter end, while the clampS, at its outer end, enters the space 11 between 2 and 3. To prevent the cloth from slipping over the surface of the plate 4, I preferably provide the plate with a roughened surface; in this instance the roughened surface is produced by puncturing the plate to provide ragged projections 12, against which the cloth is held by the clamp or clip 7 The clamp 7 acts to hold the cloth flat against one face of the plate 4 as shown in Fig. 4, while the clamp 8 acts to retain the folded over end 13 of the cloth against the opposite side of the frame 10, as shown in Fig. 5. The clamp 7 will force the folded over ends 13 of the cloth into the space 11 between the

arms

2 and 3, thereby tending to draw the cloth taut. Fig. 3 illustrates the manner of applying the cloth to the rack 5.

.As illustrated in Fig. 3 the frame 10 is normally out of alinement with the handle 1, being held in such position by the set or formation of the

arms

2 and 3, which are,

as has been stated, preferably resilient. To

get the best results I preferably set the frame 10 at an angle relative to the handle 1, in order that the said frame will assume a position substantially in the same'plane of the handle 1 when the frame is in position for use between the window-panes.

In Fig. 6 the window-panes are indicated by 14 and 15 and the frames or sashes thereof by 16 and 17 respectively. Then the frame 10 having the cleaning-cloth 6 there on is passed through the space 18 between the pane 15 and frame or sash 16 of a window, the cloth on the frame will contact with the pane and the

arms

2 and 3 of the frame will straighten or flatten out, whereby the device can be moved up and down or from side to side between two windows with a yielding pressure, thereby producing a good cleaning effect. The resiliency of the

arms

2 and 3 will keep the frame, or cloth on the frame, against the window-pane; hence the user of the device has simply to move it across the surface of the pane.

the said arms.

I carried by 6 can be held so that the entire frame of the device is covered, thereby keeping the frame out of contact With the surfaces'of the WindoW-frames 0r sashes should they be poli shed or painted. j p
