UNITED STATES PATENT OEEICE.`
GEORGE W. DITHRIDGE, OF NEW YORK, N. Y.
BEAM OR GIRDER.
SPECIFICATION forming part of Letters Patent No. 426,559, dated April 29, 1890.
Application led August 28, 1889. Serial No. 322,178. (No model.)
To @ZZ whom t may concern:
Be it known that I, GEORGE W. DITHRIDGE, of the city, county, and State of New York, have invented an Improvement in Beams or Girders, of which the following is a specification.
My invention relates to a metal beam, girder,.o1 sill adapted for use in buildings, railway structures, car-bodies, the. I make use of upper and lower edge plates and side plates having interlocking edge tongues formed integral therewith, and bolts by which the parts are connected together.
In the drawings, Figures l, 2,3, and 4f show by cross-sectional views some of the different shapes in which Inyimproved girder orbeam is Ina-de.
In Figs. l and 2 I have shown niyiniproved beam or sill as constructed with at or nearly flat upper and lower or edge plates a a and flat side plates c CZ, the edges of which have return-bends 3 fl, to iorIn interlocking edge tongues and grooves, these return-bends being made integral with said plates, and in Fig. 1 I have shown tubular studs e e between the 'side plates c d, and bolts or rivets f f', which pass through said plates and studs and unite the parts together to form the beam or sill.
In Figs. 2 and 3 I have shown the tubular studs e and bolt f midway between the top and bot-toIn edges of the girder.
Several different forms of in terlocking tongues and grooves are shown at the edges of thebealns in Figs. l and 2, because any of these forms may be employed `as desired.
In Fig. 3 the top and bottom or edge plates a a are as half-tubes, their convex sides being outward and their edges formed with return-bends 5,which interlock with the returnbends (3 of the side plates c d. The side plates they In ay be of any suitable lengths and placed so as to leave spaces between the ends of the respective plates.
The sido'plates c (Z (shown in Fig. 4) are Vprovided with nearly half-circle stiffeningribs 8 8, the edges of the side plates interlocking at 3 and 4 with the edge plates a a.
I claim as'iny invention- The combination, in a beam or sill, oi' upper or lower edge plates and side plates having return-bend edges that interlock, and conneetingbolts7 substantially as set forth.
Signed by Ine this 22d day of Augnst,A.D. 1889.
