"SHAPED BAR F NEW YORK, N. Y.
FOR SPRINGS.
SPECIFICATION forming part of Letters Patent No. 285,324,. dated September 18, 1883.
Application filed January 30, 1883. (No model.) I
' T at whom it may concern.-
Be it known that I, RICHARD Vosn, of the city of. New York, county and State of New York, have invented an Improved Shaped Bar of Steel for the Construction of Springs for Railway-Oars and other Purposes, of which the following is a specification.
My invention consists in the two shaped bars of steel having an oval shape 011 one side and a flat or corrugated surface on the other, and by placing these two bars of steel together by facing their flat or corrugated surfaces, thus leaving the oval surfaces top and bottom, gives to the bar the curved shape desired when used as a spring. The manner of doing this I describe hereinafter. I
In the drawings, Figurel in. its top or upper half shows the two leaves having fiat surfaces facing each other, leaving the top and bottom of the leaves thus placed together oval. The lower partof Fig. 1 shows the leaves thus joined together having the surfaces facing each other corrugated, so that the upper leaf, b, sits down in the under leaf, a, and when bound or'held together prevents any lateral or slipping motion. a spring joined together, showing the oval face. Fig. 3 is a crosssection on the upper half of Fig. l on line x m. Fig. 4. 'is a like section of like part on line 3/ Fig. 5 is a cross-section of lower part of Fig. 1 on line as x, and Fig. 6 is a similar View of like part on line 3/ y. 7
In the construction of my oval-leafed spring I first take a bar having flat surface on one side and oval shape on the other. This bar I draw out to the required length, leaving the metal massed to a greater extent at and both sides of the center. The ends of course are of much less thickness-in fact, may be drawn down to a very small degree. This is readily seen set forth in Figs. 4 and 6. I have another bar drawn likewise. Then by suitable rollers I give the bars the proper curve or curved shape, retaining the ova face in the two bars when so bending, so that the said face will Fig. 2 is a top,view of form the exterior face of the spring when both are joined together. I
I make the inner or lower bar (marked in the drawings a) the eye-barthat is, the bar carrying the ey eand the bar I) superlyin g over bar a. Said bar a is held to said eye-bar by means of strap or band 0. By this means of combination of two bars, one side of each of which is oval shape, I obtain in effect one bar having four tempered surfaces, and therefore one of greater strength and durability, and of greater bearing capacity, than could be ob tained in one bar.
As shown in section, Figs. 5 and 6, by means of corrugating one leaf into the other motion of the leaves from each other preventwhich are corrugated, which, combined, are oval-shaped transversely, gradually diminishing from the center toward the ends, substanfied.
Witness my hand this 29th day of January, 1883.

tially as described, and for the purpose specithe same effect is produced and the lateral ed. The corrugation may be made by rolls As is usual, the leaf b of steel bars the inner or touching faces of
