,y WINDOW-CLEANING DEVICE.

SPECIFICATION forming part of Letters Patent No. 551,186, dated December 10, 1895.

` Appliaionrned January 30,1895. saai No. 536,730. (No man To ZZZ whom it may concern:

Be it known that I, SIMON GOLDNER, a citizen of the Kingdom of Roumania, residing in the city, county, and State of Newv York, have invented certain new and useful Improvements in lVindowCleaning Devices, of which the following is a specification.

rlhis invention has reference to an improved window-cleaning device by which both sashes of a window canbe readily cleaned from the outside of the window without necessitating the sitting on the sill and washing the same from the outside, which mode of cleaning windows is connected with considerable danger of injury to life and limb; and the invention consists of certain details of construction, which will be fully described hereinafter, and finally pointed out in the claims.

In the accompanying' drawings, Figure l represents a front elevation of my improved window-cleaning device, showing the same as applied to a window-frame. Fig. 2 is a side elevation of the same, showing the sashes in vertical transverse section. Fig. 3 is a horizontal section on line 3 3, Fig. 2, drawn on a larger scale. Fig. 4 is a horizontal section on line 4 4, Fig. 2. Fig. 5 is a vertical central section on line 5 5, Fig. 4. Figs. 6 and 7 are details of the device for washing the glass panes of the sashes, and Fig. 8 is a vertical transverse section of the device for drying the same.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A A represent the sashes with which my improved windowcleaning device is to be used.

The Window-cleaning device consists of a base portion B, which is provided with a stationary piece l) near its inner end and with a transverse stationary piece b at its outer end. In the base-piece B is applied the horizontal portion or shank of an angle-plate or slide C, which is preferably made of wrought-iron or other suitable material, and to which the lower end of an upright guide-post D is applied. To the under side of the base-piece B is likewise applied a transverse strip b2, which rests against the bead on the sill A2 of the window-frame, as shown clearly in Figs. 1 and 2. An adjustable clamping-screw ZX is arranged on the inner stationary strip l), the

outer transverse piece b of the baseapiece B being placed against the outer surface of the lower rail of the sash or saslies A A', while the end of the clamping-screw is tightly screwed up against the inner surface of the lower rail of the sash or sashes A A', as shown in Figs. 2 and 3. The upright post D is at'- tached by suitable screws or otherwise to the adjustable slide O, the guide-post being further provided at its upper end with an arm D', which bears by means of an elastic strip or pad do against the upper part of the pane of the outer or inner sash, according as the outer or inner sash is to be cleaned.

The horizontal portion of the slide O is clamped in position on the base-piece B by means of a clamping-screw O (shown in Figs. l, 2, and 3) after the slide is adjusted in the proper position in the base-piece B. On the upright post or guide-piece D is guided, by means of inner and outerantifriction rollers e and e0, respectively, a vertically-reciprocating carriage E, which is preferably made of suitable sheet metal. As the carriage is of sleeve form, so as to encircle the post, and as the antifriction-rollers are arranged at the front and rear of the same, there is absolutely no danger of the carriage being accidentally displaced, and the saine is always guided on the post without any binding action.

The upright post D is provided with a longitudinal groove CZ in its outer surface for guiding the actuating-cord E, which is provided at its inner ends with handles e', and which is guided by pulleys e2 e3, arranged near one side of the base-piece B, then over one half of a double pulley e4, arranged in a recess in the lower part of the upright guidepost D, then in upward direction through the carriage E and over a guide-pulley e5 at the upper end of the guide-post D, then along the groove CZ of the guide-post, back over the second half of the double pulley e4, and then over the guide-pulleys e3 and e2 at the opposite side of the base-piece to the inside of the room. The cord E passes through a guidetube eX of the carriage E and can be iirmly clamped in said guide-tube by means of a clamping-screw e, as shown in Fig. 5,'so that the operating-cord E is firmly connected to the carriage and the latter thereby compelled to follow the mot-ion of the cord E when the salne is operated alternately in one or the opposite direction by the hands.

The carriage E is provided with pivoted and spring-actuated jaws ff (the spring being f) which extend from the carriage in forward direction toward the glass pane of the sash, said jaws being preferably serrated at their adjacent edges, so as to engage the shank of a cleaning or drying device F, according as the washing or drying of the glass pane is to be produced. The washing attachment is composed of a hollow tube F', provided with openings and open at one end for being supplied with water. The shank and tube are surrounded by felt or other covering F2, as shown in Figs. G and 7.

The drying attachment is composed of a shanked tube F3 without apertures and of a heavier felt covering F4, extending over the tube and shank, as shown in Fig. 8.

My improved cleaning device for windows is operated as follows: The base-piece B is placed in position on the window-sill, so that its transverse strip lrests on the same, while the guide-post rests on the outer portion of the sill, the lower end of the guide-post being for this purpose extended below the slide C. The outer transverse piece b is placed against the lower rail of the upper sash after it is moved down into the position shown in Fig. 2. The clamping-screw d is then applied to the lower rail of the lower sash. The slide C is then adjusted in the base-piece until the upper arm D' abuts against the upper rail of the sash, as shown in Fig. 2. The slide is then firmly clamped to the base-piece. In this position the washing attachment is placed in the jaws ff of the carriage and is then in contact with the outer surface of the pane of the upper sash. The operating-cord E is then taken hold of at its handles e and the same pulled alternately to such an extent that a vertically-reciprocating motion is imparted to the carriage of the cleaning device, the same being moved thereby from the upper to the lower rail and back again to the upper rail, and so on alternately. After the washing is completed the washing attachment F is removed from the jaws of the carriage and replaced by the drying attachment F3, which is then moved in the same manner over the outside of the pane of the sash, so that the part just washed is thoroughly dried by the absorbent felt covering of the drying attachment F3. The carriage is then moved laterally suiiiciently so that the reciprocating washi ng attachment can take the next adj oining portion of the pane of the sash, and then this portion is washed and dried in the same manner as before. The washing attachment is then again moved along the sash and operated in the same manner until the surface of the pane of the upper sash is cleaned. The upper sash is then returned to its raised position and the slide C moved forward in the base-piece until the upper supportingarm D/ and the washing attachment abut against the pane of the lower sash. The outer transverse strip l1 is then applied to the lower rail of the sash and the clamping device to the opposite side of said rail, so that the washing attachment is again in position for use, The operating-cord is then again pulled alternately by the hands and thereby the carriage and washing attachment moved alternately in upward and downward direction over the portion of the pane of the lower sash, this operation being repeated by moving the washing attachment gradually in transverse direction over the pane of the lower sash until the same is entirely cleaned. The device is then removed and put away, as the inner surfaces of the panes are cleaned in the usual manner from the inside of the room.

The advantages of my improved windowcleaning device are, first, that it takes up but little room and can loe quickly and readily applied to sashes for cleaning the same, the operation being performed entirely from the inside of the room, so as to obviate any danger to life and limb, which is incidental to the cleaning of windows when the person is sitting on the window-sill; second, the windowcleaning device is operated with great facility after the same is adjusted to the sash or sashes, as the up -and-down motion of the washing attachment does not require the exertion of great power, while the exchanging of the washing and drying attachments is readily accomplished when the carriage is at its lowermost position on the guide-post; third, the window-cleaning device, owing to its simple construction, is comparatively cheap, while it can be stored away in any closet, as owing to its small width it takes up comparatively little room.

Having thus described my invent-ion, I claim as new and desire to secure by Letters Patentl. In a window-cleaning device, the combination of a base-piece, a pair of transverse strips fixed to the upper part of the base-piece and separated a suitable distance apart, a clamping-screw passing through the inner transverse strip, a transverse strip fixed to the under side of the base-piece, said strips and clamping-screw forming the means for securing the base-piece in position, an upright post provided at its lower end with a slide guided in the base-piece and projecting below the slide at its lower end so as to rest on the window-sill, a carriage guided on the post, a washing attachment applied to the carriage, and means for reciprocating the carriage, substantially as set forth.

2. In a window-cleaning device, the combination, with a base-piece provided with means for clamping the same to the lower rails of the sash or sashes, and to the window-sill, pulleys on the base-piece, an upright guide-post supported on the window-sill and attached to the base-piece, a pulley j ournaled in the top of the guide-post, and a double pulley mounted in IOO IIO

guided at its midlength over the top pulley of the guide-post, While its outer portions are guided respectively over the end-portions of the double pulley and the pulleys of the base- Io pieee, the ends of said cord being provided with handles for reciprocating the carriage and the Cleaning-attachment, substantially as set forth.

In testimony that I Claim the foregoing as my invention I have signed my name in pres- I 5 ence of tWo subscribing Witnesses.
