Safeway Specialty Corporation,
N.- Y.. aulgnor to New York,
N. Y., a corporation of New York Application May 10, 1946, Serial No. am I a window cleaning device which can be conveniently used for washing and wiping outer surfaces of window glass panes by an operator standing near the window inside the house or inside the room whose windows are being cleaned. With 3 Claims. (Cl. -121) my device it is not necessary, therefore, to lean out or sit out of the window for cleaning the outer sides of the glass panes, and the operator can remain in perfect safety inside the room.
In my copending patent application. Serial No. 611,300, filed August 18, 1945 and which became abandoned Apr. 7, 1948, I disclosed a device for cleaning windows in which the cleaning elements such as felt and rubber strips were permanently fastened to their holder. In my present invention, I provide improved means for replaceably supporting the cleaning elements in a suitable holder without the use of any screws, bolts, or similar fasteners. r
Another object of my invention is to provide a device of a simplified, inexpensive, and reliable construction by making its principal parts, such Fig. 3 is a bottom plan view of the same;
, Fig. 4 is a fractional detailed view of a bar and holder; 4
Fig. 5 is a detailed side view of the articulated joint between the portions of the supporting arm;
Fig. 6 is an edge View of the same:
Fig. 'l is an end view of the bar showing the connecting piece:
Ilig. 8 is a side view of a modified device employing a supporting arm made of a single bar bent at an angle: and
Fig. 9 is a view of another modification in which a single straight bar is employed for the arm.
My window cleaning device comprises a holder generally designated l which may be made of metal, plastic composition or similar material, in the form of a plate having a fiat central portion 2 and angular or inclined side portions 3 and 4.
The portion 8 is provided with an angular exten-.
sion 3 forming a rectangular seat or groove for a piece of felt or sponge 4. The outer-edges of the portion I and extension I are bent inward at I for retaining the felt 4 firmly in its place in the groove. The ends of the edges I may be rounded as a holder for the cleaning elements and the articulated portions of the supporting arm of an extruded material of corresponding shapes, preferably of material suitable for such process,;as forv instance, aluminum, magnesium or of a suitable plastic composition.
Another object of my invention is to provide a window cleaning device of a general type indicated above in which the cleaning elements with their holder can be turned on a supporting arm into a desired position without removing any bolts,'screws or similar fastening means. and the holder will be yieldably retained in its adjusted position.
Still another object of my invention is to provide means to use rubber wipers in my device of a type available on the market, and nowusedfor windshield wipers on automobiles.
My invention is more fully described in the accompanying specification and drawings in'which:
Fig. 1 is an elevational view of my window cleaning device showing the same in an operative position for cleaning the outer side of a window p Fig. 2 is a fractional view of the device on an enlarged scale showing the holder with cleaning elements attached to the end of the supporting bar; 1
to facilitate insertion of the felt by sliding the same into the groove from the end of the holder. The angular extension 8 may be made separately and secured to the holder 1 as by welding or riveting, but in a preferred construction it is formed integrally with the body of the plate i as by ex trusion in the form of a'continuous strip which is subsequently cutinto pieces of a desired length. The other side portion 4 is similarly provided with an integrally formed extension ll forming a round groove or seat for the bead H of a wiper strip l2 preferably made of rubber or similar material. The outer edge of the portion 4 i tapered outward at I! for supporting the strip l2 during operation of the device. g The central portion 2 of the holder is provided with a central hole for a bolt l4 which fastens the holder to the end portion of an arm generally designated 2' and comprising articulated bars l4, l4 pivotally connected together by a bolt l The bars l8; it are preferably of a rectangular tubular shape made of metal. plastic composition or similar material, preferably by extrusion, being hollow inside to reduce their weight and cost. The bar II is placed edgewise against the outer side of the portion 2 of the holder by the bolt l4 which may be of a type known as carriage" bolt, having a rectangular portion ll' under its head for preventing rotation of the bolt in the bar II. The boltis tightened in its place by a nut ll, lock nut It and a spring washer II. Thus the holder i can ,changes and modifications.
be turned in a desired position without the necessity of releasing the nuts l8, l9 and will remain in the adjusted position by friction of the spring washer. I have found that it is preferred to use the holder when it is placed at right angles to the bar iS-as shown in Fig. 1 with either felt or rubber wiper at the top for cleaning a window pane 2|. To center the holder in this position, the outer surface of the central portion 2 may be provided with a transverse concave groove 22 engaging the convex edge of the bar I! as shown more clearly in-Fig. 4. Thus the holder is firmly held in a position at right angles to the bar II but can be turned for reversing the positions of the felt and rubber by applying sufllcient force ,to overcome the resistance of the spring washer 2|. A longitudinally extending groove 22' may alsobe provided for retaining the holder in a vertical position. 1
The articulated joint between the bars 15 and i6 is formed'with end pieces 28, 24 fitted in the ends of the bars l5, l6 and secured as by rivets ll. The abutting suniaces of the end pieces are provided with interlocking teeth or serrations 26 and with holes for the bolt l1 tightened by a wing nut 21. "The bars l5, 16 can be placed at any desired angle to each other and locked in this position by tightening the nut 27. The end bar It is provided with a handle 29, preferably of rubber or similar material. I
A modiiied device is shown in Fig. 8 in which the holder l is supported on an arm 30 made of a single piece and bent in the middle at a desired angle.
Another modification is shown in Fig. 9 in which the holder I is supported on a straight arm' II.
It will be understood that'various features and with said longitudinal portion; and means to rotatably and adiustably attach the holder to the other end of the arm.
2. A window cleaning device comprising a holder of a generally rectangular shape, formed with an intermediate portion and inclined sides extending therefrom with longitudinally extending slots in the two opposite free edges of said sides for ca ying cleaning elements in the form of strips, said intermediate portion having an opening therethrough; an arm having a handle at one end and a transverse opening adjacent the other end thereof for registry with said opening through the intermediate portion, whereby said intermediateportion and a longitudinal portion of the arm adjacent the other end are adapted,
to be connected in parallel. relationship, one of said sides forming an acute angle with said longiprinciples of each of the embodiments of the invention above described'or referred to may be utilized or substituted in the other embodiments.
