Protective covering for glass panes.

Application filed July 26,1915. Serial No. 42,053.

figuring of the glass occurs through the handling thereof, either during shipment or installation in the presence of some of the mentioned staining materials and can readily be obviated by a protective covering adapted to receive the stains and prevent a contamination thereby nf the protected pane.

Accordingly, this invention proposes to provide a protective covering formed of a heavy paper, which may be waxed or similarly treated in order to toughen it as well as rendering it transparent. A sheet of paper A of the dimensions of the. pane to be covered is' provided for each of its surfaces. Each of these paper coverings has its margin provided with a strip B the reverse side of which is coated with a suitable adhesive substance, for the entire perimeter of the paper sheet. Lines of perforations C separate the gummed strips B from the central portion of the paper in the. manner clearly illustrated. . .

The glass panes are equipped with the paper protective covers before being shipped by the manufacturer, the adhesive edges of each covering being moistened and pasted directly upon the surface of the glass, so that the. pane is thoroughly protected against the stains of carelessly used paint, putty, oil and the like. After the glass has been inserted within its frame and all handling in- 85 cident to the installation thereof is finished, an incision may be made along the perforations at one of the corners of the paper sheet and the latter then torn off in the manner illustrated in Fig. 2. The gummed edges 90 B of the sheet do not need to be removed for the reason that they are covered by the . securing putty for the glass pane. Both surfaces of the pane are thus protected and are fresh for use immediately after installation without any of the previously necessary and arduous cleansing.

While in the· foregoing, however, there has thus been illustrated in the drawings, and . described in the specification such combination and arrangement of elements as constitute the preferred embodiment of this invention, it is desired to emphasize the fact that such minor changes in the matters of proportion and degree may be made in later adaptations of this device as shall not alter the spirit of the invention as defined in the appended claim.
