Application filed December 2,1892, Serial No. 453,835. (No model.)

To all whom it may concern:

Be it known that I, Thomas N. Rogers, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia, State 5 of Pennsylvania, have invented certain new and useful Improvements in StrengtheningStrips, of which the following is a specification, reference being had therein to the accompanying drawings.

to This invention relates to certain new and useful improvements in strengthening strips for use upon trunks and analogous articles, and my new strengthening strip serves not only to replace the wooden strip but also as a 15 corner protection to take the brunt of the knocks as the trunk is pitched from place to place.

My improved strip comprises a sheet metal corrugated strip with a backing or filling in 20 the corrugation thereof, the strip having a corrugation at right angles to the main corrugation to serve at a corner not only to strengthen the trunk at the corner but to protect the same upon both sides of the corner.

Other objects and advantages of the invention will hereinafter appear and the novel features thereof will be specifically defined by the appended claims.

The invention is clearly illustrated in the 30 accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, and in which—

Figure 1 is a vertical cross section through a trunk provided with some of my strength35 ening strips. Fig. 2 is an enlarged cross section through the strip.

Like letters of reference indicate like parts throughout the several views.

Referring now to the details of the draw40 ings by letter, A designates a strip of metal, preferably sheet metal, shaped in any suitable manner to form a corrugation or convex portion a running longitudinally thereof and which corrugation may be of any desired size 45 relatively to the width of the metal strip, the corrugation being preferably though not necessarily in the center of the strip and leaving portions a' to lie flat against the body of the trunk and perforated to receive the means 50 which are employed to fasten the same in place.

B is a strip, of any suitable material, preferably wood, fitted to the corrugation as shown and this may be held therein in any suitable manner, as by brads, or analogous means b 55 which need be only of sufficient length to hold the parts against separation. In order to further protect the corner and extension as is provided which may be of greater or less length as seen in Fig. 2 and formed between 60 the same and the corrugation a with an additional corrugation a^s at right angles to the corrugation a as seen in Fig. 2, and in this corrugation, which may be smaller or larger than the corrugation a, as may be deemed 65 best, is secured a backing or filling C, preferably of wood as seen in said Fig. 2 and'in the forms of strips at the corners in Fig. 1 in which is shown a section of a trunk provided with some of my strips. 70

The strips thus constructed can be placed upon the market in lengths and readily applied by trunk manufacturers or by anyone else; they may be employed to replace split and damaged wooden strips upon trunks in 75 use. The metal portion may be formed of steel, iron, brass, gun metal or any desired material and may be as ornamental as desired. The metal protects the backing or filling and prevents breakage thereof, and the 80 backing or filling prevents disfiguration and breakage of the metal at the corrugations.
