Specification of Letters Patent. Patent d lw 17 1921 Application filed November 16, 1920. Serial No. 424,494
To all whom it may concern:
Be it known that I, Lornsn S. KnAoKn, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Window-Cleaners, of which the following is a specification.
This invention relates to improvements in devices to be used for cleaning the glass panes of windows, andit consists incertain peculiarities of the construction, novel .arrangement and operation of the various parts thereof, as will be hereinafter more fully set forth and specifically claimed.
The principal object of the invention is to provide a cleaner for windows which shall be so made as to be particularly adapted for cleaning the panes of both the upper and lower sashes of windows without the necessity of the operator getting outside of the sashes or window frame.
Another object of the invention is to provide a cleaner or polisher for windows or other flat surfaces, such as walls and ceil ings of rooms, the tops of tables, and the Walls of furniture, which can be operated.
manually or when necessary, by means of a detachable handle.
Still another object of the invention is to provide simple and efficient means for easily securing over the rubbing face of the body sash or lowering the upper sash in the operation of cleaning the windows.
A further object is to provide a cleaner for windows and the like of the above mentioned general character, which shall be' simple and inexpensivev 1n COIlStILlCtlOIl,
strong, durable and eiiicient in-operation,
Other objects and advantages of the invention will be disclosed in the following description and explanation.
In the accompanying drawing which serves to illustrate an embodiment ofthe .in-
vent1on Figure 1 is a rear face view of the cleaner showing the parts in their normal positions I and illustrating the handle shortened for the convenience of illustration;
F 1g. 2. is :a longitudinal sectional view taken on line 2-2 of Fig. 1 looking in the direction indicated by the arrows.
F 1g. 3 is a front or face view of the cleaner showlng a fragment of a cleaning cloth in about the position it may be held thereon near its ends when'such cloth is used in conmotion with the cleaner, and
F 1g. 4 is an edge view of the body of the cleaner anda portion of the handle thereof.
Like numerals of referencerefer to correspondlng parts throughout the different views of the drawing. V
The reference numeral 5 designates the body of the cleaner, which maybe made of any suitable size, form and material, but preferably, substantially triangular in shape as shown and of metal. This body is provided on one of its surfaces, which will hereinafter be called the rubbing or front surface, with a depression 6 which is substan-' tially coextensive with the body 5 and of the same shape and is formed by means of forwardly extended flanges 7 provided on each of the edges of the body. i 7
Within the depression 6 is located a pad or plate 8 of resilient material such as rubher, which is transversely corrugated or formed with'transversely extended ribs 9 as is clearly shown in Fig. 2 of the drawing. The free edges of the ribs 9 of the member 8 project forwardly of the flanges 7 so as to be adapted for contact with the panes ofglass or other fiat surface. By this arrangement it is apparent that the resilient ribs which are spaced from one another will act to thoroughly remove water from the glass panes 10 on its .outer surface and that the opposite portion of the. body 5 or the base of the .ened' and is provided with a groove or notch I lateral extensions 16 on a pair of slightly re triangular figure formed by said body is provided with a pair of alined but spaced enlargements 11, see Figs. 1 and 2, each of which has in its outer end an opening to receive the ends 12 of a wire clamp 13 which is triangular in shape as shown, or of a shape to correspond with the shape of the body 5 and of a size to fit snugly but detach-f silient arms 17 which constitute a part of the handle of the cleaner.
As shown in Figs. 1 and 2 of the drawing, thearms 17 are-bowed or curved from each other be inning at the unctu're thereof with the extensions 16 and terminating at a point near the base of the triangular body or plate from which latter point they are located in parallelism with one another and by pref erence are held together side by side by means of a clip 18 surrounding the same and soldered or otherwise fastened thereto. By reference to said views of the drawing it will be further seen that the arms 17 are curved outwardly from the plate or body 5 for a slight distance and are then extended in a straight line. By this construction, it is obvious that when the extensions 16 of the arms 17 are inserted in the openings 15 of the bosses 14:, the plate or body 5 will be carried by said arms in such a way that said body will have tilting movement on the ex tensionslB thus enabling the rubbing surface or front of the body to be maintained in proper position on the pane of glass or other surface being cleaned no matter what position the handle of the device may occupy. v
Furthermore, it is evident that pressure on the arms 17 will, by reason of the peculiar formation of said arms, have a tendency to force the extensions 16 outwardly and thus prevent their accidental dislocation or displacement from the openings 15 for said extensions in the bosses 14; of the body. The outer or free ends of the arms 17 are fastened inany suitable manner to one end of a section 19 of the handle, the other end of which is provided with a socket 20 to receive a detachable section 21 of the handle, which latter section may be used when desired. The wire clamp 13 is by preference covered at its sides and base portions with rubber tubing 22 which will assist the clamp 13in holding in position on the body 5 a cleaning. cloth 23 or a piece of any other suitable cleaning material which may be interposed between the body 5 and the clamp 13 by disengaging the apex or portion of the clamp depression of the body.
opposite the base of the body or triangular figure from the retaining groove 10 in the apex of said body opposite its base when it is apparent that the clamp may be turned on its pivots formed by the ends 12 of the clamp. and the bearing enlargements 11 of the body of the cleaner. l Vhen thus separated the ends of the cleaning cloth 23 may be placed across the plate or body 5011 the front or rubbing surface thereof in about the position shown in Fig. 3 of the drawing, when by pressing the clamp 13 into engagement with the body 5, it is manifest that the cloth will be held against accidental dislocation in such away that it can be used for wiping or washing the surface to be cleaned.
By my improvements, it will be understood that the jointed or sectional handle will provide means for reaching to the top of the window pane or panes of the upper sash while the latter is in its normal position, and thus enable the entire surface of the panes of said sash to be thoroughly cleaned on the inside of the room.
Assuming that the lower sashis in its normal position, the upper sash can be lowered to any desired distance, thus separating the meeting rails of the sashes and permitting the cleaner to be inserted therebetween and used for cleaning the adjacent surface of the sashes. By further lowering the upper sash,
it is manifest that the outer surface of the with a thin fiat substantially trinagular shaped body having its faces parallel and provided on one of its faces with a depression substantially co-extensive with said face, said body having at one of its ends a pair of spaced apart alined enlargements, each of said enlargements having in its outer 'end an opening, of a clamping member corresponding in shape to that of said body adapted to fit around the perimeter of the latter, said clamping member having its adjacent ends located in the openings of said enlargements for pivotally connecting the clamping member and body together,.and a transversely ribbed pad located 2. In a window cleaner, the combination with a thin fiat substantially triangular shaped body having its faces parallel and provided on oneof its faces with a pair of spaced bosses, each of, said bosses having in its inner end an opening, said body having atone of its ends a pair of spaced apart al ned enlargements, each of enlarge:
in the said p 1. In a window cleaner, the combination ments having in its outer end an opening, vided at one of their ends with lateral ex- 10 of a clamping member corresponding in tensions located in the openings of said shape to that of said body adapted'to fit bosses, said arms being oppositely curved around the perimeter of the latter, said from one another and also curved upwardly clamping member having its adjacent ends from the body and longitudinally with relocated in the openin s of said enlargements spect thereto, the outer portions of said arms 115 for pivotally connectlng the clamping membeing located in parallelism and connected her and body together, and a handle for the together.
