GEORGE W. TYLER, OF WASHINGTON, DISTRICT OF COLUMBIA.

WINDOW-CLEANING DEVICE.

Application filed June 27, 1923. Serial No. 648,056.

To all whom it may concern:

Be it known that I, GEORGE W. TYLER, a citizen of the United States, and residing in Washington, D; (l, have invented new and useful Improvements in Window- Cleaning Devices, of which the following is a specification.

An object of this invention is a window cleaning device adapted for cleaning all windows, large and small both inside and outside and particularly the outside of all slidable windows irrespective of the height from the ground.

A further object of this invention is a window cleaning device of a portable character which is light and easy of manipula tion and which can be used without danger to either the operator or to passers by.

A still further object of this invention is a window cleaning device which is of simple construction and which can be manufactured at a comparatively low cost.

Other objects and advantages will be parent from the following specification and drawin s which form a art hereof and in which Fig. 1 is a perspective view of a portion of a window and the cleaning device in position to clean the outside of the upper sash which is shown in lowered position.

Fig. 2 is a side elevational view of the cleaning device shown in position for cleaning the outside of the lower sash, the two sashes beingshown in section.

Fig. 3 is a perspective View of a portion of the device in partly disassembled relation.

Fig. 4 is a side elevational view of a modified form of handle member.

Fig. 5 is a transverse sectional view of a modified form of wiper member which may be used in place of that shown in the previously described figures; and

Fig. 6 is a perspective view of the wiper member partially enclosed in a pad separated by a moisture proof layer.

Referring to the drawings the numeral 1 designates a handle which is substantially U-shaped with one arm considerably longer than the other, the handle being preferably made of a single piece of light tubing of brass, aluminum, or galvanized iron, it being preferable that the cheapest material be used so long as it will submit to the bending operations necessary in the manufacture of the handle, lightness of material also be I ing highly desirable. The object of the U-shaped handle is that it may be positioned with the bend cross ing the sash either above or below and with one arm on the inside and the other on the outside as shown in Figs. 1 and 2; The end ofthe longer arm is externally threaded as indicated by the numeral 2 for a purpose to be later described.

The numeral 3 designates a socket member which is internally threaded at one endas designated at 4 in order that the socket member may beconnected with the shorter arm of the handle, which shorter end is externally threaded for co-operationwitn the threads 4. 1

The end of the socket member opposite the threaded end is cut ona curve as shown in Figs. 2 and 3 thus forming a flat pros jection or lug 5, the said projection being deflected toward the longitudinal axis of the socket member as is clearly shown'in Figures 2 and 3.

Co-operating with the lug 5 is a two part clamp designated by the character W, the parts being designated at 6 and 7 respectively.

The clamp parts 6 and 7 are in plan substantially of the same shape, each comprising a perforated lug 8 and a gradually widened gripping member 9 as clearly shown in Fig. 1. i

The clamp part 6 in edge elevation is slightly bent as at 10 and is provided with a substantially right angled extension 11.

The clamp part 7 in edge elevation is bent outwardly from the lug 8 as at 12- and is then twice bent inwardly as shown in Figs.

. 2 and 3 terminating in an extension 13.

It will be noted from the above description and particularly Fig. 2 of the drawing that the clamp parts are so formed that the wiper member, to be later described, when in clamped position, assumes an angular position relative to the socket member 3, in other words, when completely assembled the clamp extends angularly in one'fdirection while the wiper member extends angularly in an opposite direction.

The object of the angularly related parts as above described is that the clamp will more securely hold the wiper when same is subjected to a pull in the direction of the socket member and further that the wiper to be cleaned.

:Themember 15is rolled. about the core 14 and :may...consist of any desirable material that is well adapted to cleaning.

. The object of the threads2 on the longer arm off. the handle is that the socket memb er-3 maybe removed from the shorter arm and secured. to the longer arm when it is desired to clean at a height difficult to reach withthe shorter end.

- Thexsocket member 3 may be removed from *thehandle and be used as 'a handle itself. especially the windows.

Theclamp member is pivotally secured to the lug 5 by means of a bolt 16 and is held imposition by the thumb nut 17.

The clamp is pivoted so that it can be turnedih a plane-at right angles to the commonfplane of the arms "only. It is to be iioted that in use the clamp should be so adjustedithat the wiper willextend upwards toward the glass with which it contacts in use as the handle is always pulled downward bothfin cleaning the inside and the outside, thusin F ig'. 1 the clamp is turned so that the for wiping the inside of wiper in end view extends inwardly and up-.

wardly while in Fig. 2 the clamp is reversed, i. e, iven a'180? turn so that the wiper in end viewextends inwardly and upwardly.

Inrthe use of the'device the core is covered with a suitable wiper pad which pad is moistened in any suitable manner and the cbre and pad constituting the. wiper are then. inserted in. the clamp in the desired position. In, cleaning the outside of both sashes,- the sashes are shifted as is common when cleaning by the old and common method.

In cleaning the inside of both sashes the clamp should be'removed and placed on the outside of. the lug 8 in order that the wiper will inend view extend upward toward the sashiand the socket member may be secured to thelonger arm of the handle to clean the upper sash.-

In-Fig. -4-is disclosed a modified form of handle which consists of three parts, 18, 19 and 20 respectively, the parts 18 and 20 are straight pieces, the piece 20 being considerably longer than the piece 18, the pieces 18 and 20 being detachably connected with the Ushaped member 19 which member 19 is internally threaded at its ends and engages external threads on the adjacent ends of members 18 and 20. The modified form of handle in side view is of the same form as disclosed in Figures 1 and 2.

In the modified form of handle either member 18 or 20 may be used as a handle it self, such, for example, in cleaning the inside of the window.

In Fig. 5 is disclosed a modified form of wiper member in which the 'core 14 is circular in cross section and the pad or wiper 15 is wrapped about the core 14, the object of this form being that the pad may be rotated about the core to expose clean surfaces to the Window to be cleaned.

In Fig. 6 is disclosed the wiper member of the previous figures, viz, core 14 and moistened pad 15. After having cleaned one or more windows it may be desirable to dry them or even to wipe others with a dry pad and this is accomplished by placing a dry pad'21, over the moistened pad 15 and interposing between the pads 15 and 21 a moisture proof pad of oil cloth, rubber or other similar material as indicated at 22. The edges of the pad 21 are brought together and secured by safety pins or other suitable means.

Having described specific embodiments of my invention it is to be understood that I do not limit myself thereto but reserve the right to all modifications which fall within the scope of the subjoined claim.

What I claim is A window cleaning device comprising a U-shaped member, one of the arms of which is substantially one half the length of the other arm thereof, and a wiper holder having a socket adapted to be detachably mounted on the end of either arm of said member; the proportions of parts being such that the entire interior surface of a closed window may be cleaned with the wiper when attached to the long arm, and the entire exterior surface of a Window may be cleaned only by reaching over the top to clean a half section and around the bottom to clean that half section with the wiper attached to the short arm.

In testimony whereof I afiix my signature.

GEORGE W. TYLER.
