N0. 588,027. Patented Aug. 21, 1888.

UNITED STATES PATENT Games.

ENGELBERT DIETRIGH, OF CINCINNATI, OHIO, ASSIGNOR OF ONE-HALF TO ALBERT MAIR, OF SAME PLACE.

PICTURE= SPECIFICATION forming part of Letters Patent No. 388,027, dated August 21, 1888.

Application filed October 17, 1887.

To all? whom it may concern.-

Be it known that I, ENGELBERT DIETRICH, a resident of Cincinnati, in the county of Hamilton, State ofOhio, have invented certain new and useful Improvements in Picture-Frames, of which the following is a specification.

The object of my invention is to provide a device to be attached to the rabbeted portion on the back of the frame'molding to prevent any surplus water when washing the frame and glass from running in back of the glass and injuring the picture. It also serves to effectually keep out all dust, and thereby preserve the picture.

In the accompanying drawings, Figure 1 is a view in elevation of the back of a pictureframe, part of the back and glass being removed. Fig. 2 is a view, on an enlarged scale, of a piece of frame-moi ding provided with my improvement. Fig. 3 is a view similar to Fig. 2, showing the position of the elastic strip when the glass is placed thereon. Figs. 4 and 5 show modifications in the mode of attaching the elastic strip to the molding.

The preferable mode of construction is as follows: Two longitudinal grooves. a, are cut in the back surface of the rabbeted portion A of the molding B, into which the outer edges of the elastic strip 0 are placed, as shown in Figs. 2 and 3. These grooves a are preferably cut into said surface at an angle of about fortyfive degrees thereto, the better to retain the elastic material in position. This strip 0 is preferably rubber, but may be of any suitable Serial N 0. 252,556. (No model.)

elastic material. This rubber strip is cut wide enough, so that when placed in the grooves there will be formed the crown-tip, as shown, extending above the surface of the rabbeted portion A.

When the glass is placed in position in the 0 frame, the tendency is to flatten the elastic strip, as shown in Fig. 3, and when thus flat tened said strip continuously bears against the glass and prevents any water or dust from entering between the frame and glass.

Instead of having two grooves at an angle to the surface, as beforedescribed, the two edges of the elastic strip may be placed in one groove, as shown in Fig. 5, or one edge only, as shown in Fig. 4. The dotted lines in Figs. 4 and 5 show the position of the elastic material when not in use.

The advantages of my invention are apparcut, and have been partially stated, and, taken in connection with its cheapness of manufacture, makes a very desirable frame for protecting valuable pictures.

What I claim as new and of my invention, and desire to secure by Letters Patent, is-

A pictureframe having one or more cuts or grooves, a, in the rabbeted portion thereof, in combination with an elastic strip of material, as O, the two edges of said strip being inserted into said grooves, substantially as set forth.

ENGELBERT DIETRICH.
