ADAM HAY, OF NEWARK, NEW JERSEY.
IMPROVEMENTIN COMPOUND GIRDERS.
Specification forming part of Letters Patent No. I 79,1 14, dated June 27, 1876; application filed May 19, 1876.
[0 all whom it may concern Be it known that I, ADAM HAY, of Newark, in the county of Essex and State of New Jersey, have invented a certain Improved Gompound Girder, of which the following is a specification My invention consists in an improvement on my former patent for a compound boxgirder, No. 164,734, June 22, 1875viz., in strengthening the girder by the application of an element to the upper side.
Figure 1 is a side elevation of a girder. Fig. 2 is a crosssection, showing the added part. Fig. 3 is a longitudinal section, showing the same. Fig. 4 is a plan, showing the added part on each side. Fig. 5 is across-section, showing a modification of the-added part.
My former patent girder had the bed or base B of castiron, with cast-iron ribs 0, and the sides A, of Wrought-iron, bolted to the bed and to the ribs; but the upper side was left open, thus leaving unoccupied a place of strengthening, which may be utilized to advantage. I now take the girder constructed on my former plan, and to the inside of the upper edge of sides A I bolt, through the flanges a, the angle-iron strips E, made of wrought-iron running the Whole length ofthe girder. That part of the strip facing on the top may he of such width as experiment shall prove most desirable; or, instead of these strips, there may he a channel-iron plate, F,
as shown in Fig. 5, extending across the whole .of the upper side; and this plate may be In the compound girder having the castiron base B and wrought-iron sides A, the combination of the angle-iron strips E therewith, substantially as and for the purpose specified.
