METALLIC STRUCTURE FOR RUNNING-BOARDS.
Specification of Letters Patent.
Patented Mar. 23, 1920.
Application filed July 26, 1919. Serial No. 313,470.
To all whom it may concern:
Be it known that I, WALTER J. Srmo, citizen of the United States, residing at White Plains, in the county of Westchester and State of New York, have invented certain new and useful Improvements in Me-. tallic Structures for Running-Boards, of which the following is a specification.
This invention relates to a metallic structure for running boards and particularly to the construction of the running board tread or mat and the binding molding for retaining the same in position. j
The invention has for an object to provide a novel and improved .bi-metal structure composed of a sheet metal base and a superposed layer of noncorrosive sheet metal inclosing the base and secured thereto. A further object of the invention is to provide a construction comprising closely contacting layers of different sheet metals having raised portions upon the tread face thereof stamped or pressed from the con tacting layers so as to nest the same to gether.
Another object of the invention is to provide an improved form of metallic molding for a running board consisting of an angular sheet metal base having a noncor rosive sheet metal covering bent over the opposite edges thereof and formed with projections at the tread portion pressed from both layers of material.
Other and further objects and advantages of the invention will be hereinafter set fortli and the novel features thereof defined by the appended claims.
In the drawing- Figure 1 is a perspective showing the running board;
Fig. 2 is an enlarged detail sectional perspective, and Fig. 3 is a vertical section showing a modified application of the in- .vention.
Like numerals. refer to like parts in the figures of the drawing.
The numeral 1.0 designates the tread or mat of a running'board which is herein shown as formed from a sheet metal base plate 11 of iron, steel or similar material of proper thickness to secure the desired strength and rigidity and may be supported in any desired manner. This base is covered and inclosed by a sheet 12 of noncorrosive metal, such as aluminum, which is secured thereto at its opposite sides by the overbent portions 13 embracing the ed es of the base. These plates when assemb ed may be provided with any desired character of projections upon their upper or tread face, for instance as shown at 14 where they are pressed from both layers The base is of angular form and consists of the upper or tread face 16 and the front face 17 having at its lower edge an offset 18-. The outer faces of the base are com pletely covered by alayer 19 of noncorrosive sheet metal. such as aluminum, and the side or longitudinal edges of this coveringare bent over the corresponding edges of the base, as shown at 20, to inclose the same and retain the covering. in position. The tread face of such molding are usually provided with ribs or projections and in the present construction they are formed from both layers of material and comprise corrugations as indicated at 21. which by nesting together bind the base in close contact or formation to prevent any movement thereof upon each other. Any desired character of projections may be formed upon the molding and it may be secured in position to retain the mat by any form offastening device. such as shown at 22::- For this purpose the molding may be provided with an inturned flange 23 at its lower portion In Fig. 3 a very desirable attaching means for the molding is shown. The base or support 24 for the mat or cover 25 may be of any preferred material, for instance wood, and the edges of the mat are secured thereto by an attaching strip 26 having a corrugated upper face 27 and a frontface 28. This stripis secured by fastening d'vices 29 extending therethrough and through the mat into the support. The corrugated face of the strip nests or fits into the contacting corrugated face of the molding and thus retains the latter against lateral movement thereon, while the lower edge of they molding is at tached to the support by the fastening devices 22 extending through the flange 23.
While the face of the strip and molding are shown as corrugated, other forms of projections or raised sections may be used and arranged to nest together or interlock for the same purpose. This attachingmeans entirely conceals the fastening devlces and stiflens the tread face of the molding at the points of greatest wear so that a lighter weight of molding may be used than would be otherwise necessary.
In the construction of both the mat and molding the noncorrosive face layer embraces the longitudinal edges of the base and when the ribs or projections are pressed from both layers any slack between the same is taken up and a firm intimate contact secured which efl'ectually preserves the base metal from corrosion and provides a tread or wearing surface of suflicient thickness to overcome the objections to a plated or coated surface. The invention presents a bi-metal structure of proper rigidity and attractive design in which a noncorrosive wearing surface of the desired thickness is firmly secured to the base by the raised sections pressed from the assembled sheets of material which also offer resistance to slippage of the foot in the use of the running board.
The invention presents a simple, eflicient and economically constructed form of mat and molding for the step or running board of any type of automoblle or other vehicle.
What I claim is 1. A metallic edge molding structure for runningboards consisting of an angular base of sheet metal and a sheet metal cover-. ing layer inclosing the same and secured thereto at its opposite edges.
2. A metallic-tread surface for running boards consisting of a sheet metal base and a sheet metal covering secured thereto at its edges, both of which layers are provided with raised sections closely nested together.
3. A metallic tread surface for running boards consisting of a sheet metal base, a noncorrosive sheet metal covering bent over the opposite edges thereof, and raised sections at the tread portion formed from both layers of material whereby the covering is brought into close contact with the base.
4. A metallic edge molding for running boards consisting of an angular sheet metal base having an offset at the lower edge of its front face, a noncorrosive sheet metal layer completely covering the outer face of said base and embracing the opposite side edges thereof, and a corrugated tread face formed from both layers of material.
5. A metallic edge molding for running boards consisting of an angular sheet metal base, a noncorrosive sheet metal coverin secured to the opposite side edges thereof, raised sections formed from both layers of. material at their tread face, and an attachliJng flange, disposed at the lower edge of said ase.
6. A metallic edge molding for runnin boards consisting of an angular sheet met-a base, a noncorrosive sheet metal covering secured in direct contact therewith, raised sections formed from both layers of material at their tread face, an attaching flange disposed at the lower edge of said base, and an attaching strip disposed beneath the tread portion of the molding and adapted to interlock therewith.
7. A metallic edge molding for running boards consisting of an angular sheet metal base, a noncorrosive sheet metal coverin secured in direct contact therewith, raise sections formed from both layers of materiala't their tread face, and an attaching strip disposed beneath the tread portion of the molding and formed to interlock with the raised sections thereof.
8. A metalliced e molding for running boards consisting of an angular sheet metal base, a noncorrosive sheet metal coverin secured to the opposite side edges thereo corrugations formed from both layers of material at their tread face, a support, and an attaching strip. having a corrugated upper face secured to the support and nesting in the corrugations of the tread portion.
In testimony whereof I afiix my signature.
