WINDOW CLEANING DEVICE Filed Feb. 5, 1936 I W; EMT-O2 A NEYS Patented May 17, 1938 UNITED STATES 2,118,009 WINDOW CLEANING DEVICE Herbert J aeckel, Berlin-Britz, Germany, assignor to Roland Lindemann, New York, N. Y.

Application February 5, 1936, Serial No. 62,397

1 Claim.

My invention relates to a window cleaning device and more particularly to certain improvements in a window cleaning device as disclosed in my co-pending application, Serial No. 60,27 9, filed January 22, 1936.

It is an object of the invention to provide a window cleaning device which is very simple, light, yet rugged in construction, easy to manipulate, and effective for window cleaning purposes.

It is another object to provide a window cleaning device of the character more fully set forth in my said co-pending application, with an improved means for movably connecting the two arms and for manipulating the same relatively to each other.

Other objects and various features of inven tion and novelty will be hereinafter pointed out or will become apparent to those skilled in the art upon a reading of the specification.

In the drawing which shows, for illustrative purposes only, a preferred form of the invention- Fig. 1 is a view in elevation of a window cleaning device illustrating features of the invention;

Fig. 2 is a view in elevation of the device shown in Fig. 1, taken from the top.

As has been more fully set forth in my aforesaid co-pending application, the window cleaning device includes a pair of arms having window cleaning devices, such as sponges, at the ends. These arms are adapted tobe separated to permit one cleaning device to be applied to each side of the same window pane and are preferably coextensive with and opposite each other.

In the drawing, 5-6 indicate a pair of arms having pad holding boxes or the like l-B at the free ends. Each box may hold a sponge 9 or other cleaning, washing, drying or polishing device. The two arms in the preferred form are made of aluminum comprising a relatively wide plate member l having a substantial rib ll thereon for strengthening purposes. The arms ars thus very light and yet are exceedingly strong and are preferably quite rigid. When the arms are relatively rigid they are hinged together so as to be movable relatively to each other.

In the form shown the arm 6 is divided at l2 and the two parts are hinged together as by means of a hinge pin l3 passing through appro priate ears on the two parts of the arm, as will be understood. A spring 14 of desired and appropriate strength serves to urge the arm G toward the arm so as to press the two'pads 9 towardeach other and onto the opposite sides of a window pane. Regardless of where'the separating point l2 occurs, whether in the arm 6 or the arm 5 or in the bottom of the generally U-shaped form of the arms, it will be seen that the arms are hingedly connected to each other.

In order to manipulate the arms I provide a 5 member preferably in the form of an extension l5 on one arm (in this case what is in effect the arm 5) or that part of the arm 6 to the right of the break 12 and which is rigid with the arm 5. The extension member l5 may be attached to the 10 arm 5 as by means of screws IS. The extension member l5 passes the hinge pin l3 and extends along and in spaced apart relation to the normal position of the arm 6. Thus it will be seen that the extension member l5 and adjacent part 5 of the arm 6 may be grasped in the hand and since the extension member I5 is preferably rigid with the arm 5, the arm 6 may be drawn away from the frame 5 to, say, the dot-dash line position of Fig. 1. If it is desired to hold the arm 6 in the dot-dash line position, the latch member I1 provided on the arm 6 may be moved so as to overlie the end of the extension l5 and thus hold the arms separated so that the sponges or other devices 9 may be applied and removed. When'the arms are in such separated position, the device may be moved into position over a window frame, the latter of course passing between the two arms 5--B. Even if the arm 6 is not latched to the arm 15 when it is desired to apply the device to a window, the extension l5 and arm 6 are merely grasped so as to separate the two arms sufficiently to permit the window to pass between the pads. When the device has been applied toa window, it will be seen that the spring M which is of the desired strength will firmly press the pads 9-9 onto the window pane with just the desired force and the window cleaning device may then be moved back and forth so as to wash, clean, dry, or polish the window. In order to facilitate movement of the device over the window I preferably provide a substantial and convenient hand grip I8 on one of the arms (in this case the arm 6). Thus a person standing at the inside of a window may without the necessity for reaching out or hanging over the window sill wash, dry and polish both sides of a window pane. The space between the arms is unobstructed to the bottom of the bend so that for a given reach of the arms the device may be of minimum length.

While the invention has been described in considerable detail and reference is hereby made to my said co-pending application for a fuller description of the advantages of a window cleaning device of the general type herein disclosed, it is to be understood that various changes may be made within the scope of the invention as defined in the appended claim.

I claim:

In a window cleaning device, a U-shaped arm member having one long leg and one short leg, a second arm hinged to said short leg and extend- 10 ing to the end of said long leg, a spreader member rigidly secured to said short leg and extending along the outside of said second arm and spaced therefrom, spring means at the hinge to urge said long leg and said second arm toward each other, and latch means to coact with the end of said spreader member and second arm for holding said parts together and said second arm and said long leg spaced apart against the force of said spring means.
