Specification of Letters Patent.

Patented Feb. 27, 1906.

Application filed March 6, 1905. Serial No. 248,519.

To all whom it may concern:

Be it known that we, Annie M. JOHNSON and DAVID II. ROWE, citizens of the United States, residing at Oakland, in the county of Alameda and State of California, have invented new and useful Improvements in Window-Cleaners, of which the following is a specification.

Our invention relates to window-cleaners. Its object is to provide a cleaning device which enables the operator to get at the outside of the window without exposure to the danger of a fall.

The invention consists of the parts and the construction and combination of parts, as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which- Figure 1 is a perspective view of our invention viewed from the top. Fig. 2 is a similar view from the bottom. Fig. 3 is a side elevation, in partial section, of the same.

A represents the body of the device, which is of suitable shape, size, and material. Preferably it is rectangular in outline and is transversely corrugated on its rubbing-sun face, as shown at 2, and is provided on the opposite side at one end with an angularlyprojecting plate or scraper 3.

Any suitable absorbent fabric or fibrous material, as 4, may be stretched over the corrugated surface of the body A and the ends brought up over the scraper and between the forks of the handle 5 and clamped beneath the spring-so orted plate 6.

The forke andle extends back and up ward from the body to permit of a sufficient handheld when the device is used close to the operator or in narrow spaces, the two forks o the handle being united intermediate of their ends, as shown at 7, to form a pivotseat for the spring 8, which carries the presser-plate 6, and to strengthen the handle and to provide a bifurcated end portion 9, between which the long handle 10 may be clamped by means of the wing-screw l l.

The presser-plate 6 is studded with suitable projections 12 on its under surface, here shown as formed by punching small holes through the plate from the top side. These projections act as teeth to grip and securely hold the scrubbing, rubbing, or polishing cloth or chamois 4.

The spring may be provided with a linger hold 13, whereby the end of the spring to which the resser-plate is attached may be lifted to permit of the removal or adjustment of the olishing medium 4, the spring being pivote intermediate of its ends at 14 and turnable to one side or the other of the body.

The body A is preferably rectangular to allow it to be worked into all the corners of the sash. The corrugations 2 form a good scrubbing-surface and aid materially in holding the cloth in place. The scraper 3, over which the cloth is stretched, presents a comparati-vely sharp edge for removing such dirt as may not easily be washed off with the fiat surface of the device. By omitting the cloth altogether the scraper will effectu ally remove clot and the like.

The handle-section 10 may be of any length to enable the operator to reach over the top or up from beneath any sash to clean all parts of the outside of a window. At the same time the section 10 may be tilted up and back to stand at an acute angle with the handle portion 5, shown in Fig. 3, or may be entirely removed by loosening the wingscrew 11 to permit in either case the operator to hold the device close to the body A and work conveniently at close ran e or in a s ace too short for the use of the arger hand ed device.

A scrubbing or mop cloth can quickly be removed by lifting the spring by the fingerhold 13 and turning the spring to one side and a drier or polisher of chamois, wool, or other suitable material, substituted and adjusted and clamped between the back of the body A and the late 6.

Having thus escribed our invention, what we claim, and desire to secure by Letters Patent, is-

1. A cleaner consisting of a substantially rectangular body portion transversely corrugated on its working face and provided with an angularly disposed rigid scrapcrplate on its 0 posite side, a handle and means for removab y holding the ends of a cleaning or like fabric on the back of the body portion.

2. A cleaning device comprising a body portion transversely corrugated on one side, a handle secured to the opposite side, an angnlar rigid scraper-plate secured to the hondle side of the body, a fabric passed over the corrugated surface of the body and over said scraper and having its ends brought together on the back of said body portion and a springclamp to hold the ends of said fabric, said spring-clamp being pivoted to the handle and arranged to swing laterally ol said body.

A cleaning device comprising a body portion transversely corrugated on one side, a handle secured to the opposite side, an angular rigid scraper-plate secured. to the handle side of the body, a fabric passed. over the corrugated surface of the body and. over said scraper and having its ends brought together on the back of said body portion, and a spring-clamp to hold the ends of said. fabric.

4. A cleaning device comprising a rectangular body portion, a handle secured thereto,

a spring (pivoted intermediate of its ends to said han 1e and arranged to swing laterally 1 ol' the body, and a presser-plate carried by l said spring and arranged to impinge upon the back of the body.

In testimony whereof we have hereunto set our hands in presence of two subscribing witnesses.
