FREDERICK GRETHER, OF AKRON, OHIO.

PAD FOR CLEANSlNGI GLASS SURFACIE$.

SPECIFICATION forming part of Letters Patent No. 789,421, dated May 9, 1905.

Application filed August 1, 1908- Serial No. 167,856.

To all whom, it may concern.-

Be it kn own that I, FREDERICK Gnuruun, a citizen of the United States, residing at Akron, in the county of Summit and State of Ohio, have invented certain new and useful improvements in Pads for Cleansing Glass Surfaces; and I. do declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to pads for cleaning glass surfaces such as mirrors, show-eases, windows, and the like where thorough cleansing desired.

In the accompanying drawings, Figure 1 is a perspective elevation of my new and improved pad. Fig. 2 is an edge elevation thereof, showing one end bent forward and down to reverscthe keeper to the other side.

.l he pad thus shown is essentially a hand pad and is designed to be gripped and used by hand alone and not by a mechanical gripping or holding device of any kind. My invention is therefore to be understood as different in this particular from what are known as window-washers with special holders and handles, as well as different from any and all devices in this art which call for mechanical appliances of some kind to enable them to be used.

In the construction of a pad A adapted to be used as in this invention several things are of importance. Thus, for example, the pad should have size and shape which are convenient to be held by the hand, and for this reason 1 have adopted, preferably, a substantially rectangular shape, with a length, say, of about four inches and a width of about three inches and a thickness of about one inch. These are approximate figures and may be departed from more or less either way. Then, again, the quality of the bag or cover is important, because it must be such as will not scratch or mar the glass over which it is rubbed and at the same time flexible and fairly porous. l have found that what is known as H canton-flannel wlth its woolly side outslde, is admirably adapted to this use. It has the requisite softness so as not to injure the glass, and while 1t 1s porous 1t 1s woven closely enough to retain the body of the material within the pad, which does not dissolve in use. The com pound or filling of the pad is of a character which serves first of all the purposes of cleansing, so that when the pad has been moistened by dipping it in water there will be at least measurable dissolving of the cleansing ingredients and a corresponding working out or exuding thereof through the cover, so as to serve its purpose. However, it should be understood that this pad is designed to be used over and over again during difierent days before becoming exhausted, and hence in the selection or preparation of a compound its continued or repeated use should be taken into account. As a suitable filter or body for the pad I mention sawdust, and especially cedar sawdust, and a mixture of substantially equal parts of bicarbonate of soda and whiting. Finally, the pad thus constructed and filled is preferably provided with a hand loop or keeper B. This enables the four fingers of the hand to be slipped through the keeper and to rest the hand fiat thereon, and thus most conveniently and effectively handle the pad; but it is desirable to not only have a keeper which will engage quite snugly over the fingers, but which will allow the pad to be reversed and used on either side. To this end the keeper is made just large enough to bend one end of the pad through it, as seen in Fig. 2. By reason of the pad being fiexible I can use a comparatively small loop or keeper B and which will rest well down upon the lingers and help hold the pad when the lingers are spread out thereon.

Any one skilled in the use of a pad of this kind will soon detect when it is exhausted that is, when the cleansing ingredients are all washed out.

WV hat I claim is As a new article of manufacture, a hand-pad for cleansing mirrors and other glass surfaces having a porous fabric cover and a iiller consisting of sawdust and a cleansing mixture of bicarbonate of soda and whiting intermixed with the sawdust, substantially as described.

Witness my hand to the foregoing specilication this 11th day of July, 1903.

FRED. GRETIrlElt.
