ROLLED METAL SECTIONv APPLI CATION FILED NOV. 25,1919.
Patented Dec. 14, 1920 Mg INVENTOR UNITED STATES PATENT OFFICE.
ALVIN L. ROBERTS, OF PHILADELPHIA, PENNSYLVANIA.
ROLLED-METAL SECTIQN.
Application filed November 25, 1919.
T 0 all whom it may concern Be it known that I, ALVIN 'L. Romances, a citizen of the United States, and a resident of Philadelphia, in the county of Philadel' phia and State of Pennsylvania, have invented certain new and useful Improvements in Rolled-Metal Sections; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to a rolled metal section adapted particularly to form the top and bottom members of a box girder, and it consists in the details of construction as will be more fully explained and pointed out in the claims.
The accompanying drawing shows my improvement in cross section and also shows in dotted lines a box girder built up from such section.
Box girders are usually formed 01 two web plates spaced a convenient distance apart, a top plate and a bottom plate, the said plates being united in box form by four rolled angles, one at each corner, the said plates and angles being secured together by riveting. This makes the girder consist primarily of eight pieces, four plates and four angles riveted together. Box girders are also constructed with top and bottom plates and four web plates united to the top and bottom plates by angles as before, but with the web plates made short and lattice bars used to connect the top and bottom portions of the girder. In such girders the web plates are shallow and extend but a short distance from the top and the bottom for the attachment of the lattice bars.
The object of my invention is to simplify Specification of Letters latent.
Patented Dec. 14, 1920.
Serial No. 340,574.
the construction by reducing the number of parts required in the construction of a lattice girder, and also reduce the cost of manufacture.
itle my improvement the top and bottom oi the girder are each composed of a single rolled section comprising a web 1, and two right angle flanges 2. The flanges 2 are united to the web at equal distances from the side edges of the latter, and the portion 3 of the web projecting out beyond the flange is thicker than the portion or the web intermediate the side flanges. One such rolled section constitutes the top of a girder and a similar section inverted forms the bottom, as shown by dotted lines in the drawing, the two sections being united by the plate or lattice bars 4: riveted to the oppositely disposed flanges 2 of the two sections.
Having fully described my invention what I claim as new and desire to secure by Lettors-Patent, is
l. A rolled metal section comprising a web and two integral right angle flanges on the same side o1 the web and removed from the edges thereof, the edges thereof being without flanges or other projections.
2. A rolled section comprising a webland two integral right angle flanges on the same side and removed from the edges of the web, the side edges of the web which project beyond the flanges being thicker than that portion of the web between the flanges and without flanges or other projections.
In testimony whereof, I have signed this specification in the presence of two subscribmg witnesses. I
