Leners Patent No. 66,974, dated Juzg 23, 1867.

IMPROVEMENT IN STEAM ENGINES.

"lO ALL WHOM I'l MAY CONC-EEN:

Be it known that I, JOHN L. LAY, of the city of Buffalo, in the county of Erie, and State of New York, have invented cert-ain improvements in the Method of Supporting the Cylinders of Vertical Steam Engines; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accom` panying drawings, making part of this specica-tion, in which- Figure 1 is a side elevation of' a high' and a low-pressure cylinder, arranged vertically, with the supporting' frame partially in section.

Figure?. is a horizontal section in the plane of the line z rv, fig. l.

Figure 3 is a modification of my improvement.

Like letters designate corresponding parts in all the figures.

My invention consists of the means hereinafter described of supporting the cylinders of vertical engines.

In the drawings, A A represents three or more standards firmly fastened to a base-plate, B, preferably by bolts through flanges a at their foot, which converge or incline towards each other at the top, their upper ends being secured to a cap orhorzontal fra-me, C, as'shown in fig. 1. These standards I prefer to make of iron, (although other material may be employed,) of the angular form shown by the cross-section in fig. 2. To these standards are bolted brackets D D, the arms-of which project inward and support the cylinder E which rests upon them, as shown in figs. I and 2, being bolted o1' otherwise fastened thereto. Under the ends of each of the brackets I employ a vertical post or column, G, which renders the support more firm where the cylinder is of large size. F represents the high-pressure cylinder, cast with three or more flanges gg (fig. 1)wl1ich rest upon and are bolted to the top of' a corresponding number-of standards I-I H, similar to A A, which are firmly bolted to the eapplate C, as shown. The cylinder E may be provided with flanges similar to those of a high-pressurecylinder, and be bolted to the brackets D, or it may be east with a flange, g, surrounding it, and be arranged within and bolted to the top plate C of frame A A, as represented in fig. 3. If preferred the ends of the bracket-arms may be connected by an annular plate, upon which rests andis fastened the cylinder, the columns being employed as represented, the eifect being substantially the same as when-the brackets are disconnected from each other, the flange4 of the cylinder in that case performing the same office as theannular plate. It is evident that the standards A may be made sufficiently high to supportIthe cylinder F at their top, while the cylinder E is sustained as represented in iig. 1.` This arrangement of the converging standards and their adjuncts gives great steadiness and stability to the engine hy bracing it equally in every direction, and obviates much oi' the jar and vibration which have an injurious effect on engines of` this construction, where a single rod carries the two cylinders placed in a line. It also admits of their more convenient adjustment to a true working line than when otherwise arranged and supported.

What I claim as my invention isframe for supporting the cylinders E F of vertical compound engines, composed of the converging standards A A and H II, cap or intermediate plate C, fianges g g, and brackets D D 0r equivalent, with the pillars G G, combined and arranged substantially in the manner and for the purpose set forth.

In witness whereof I have hereunto signed my naine in the presence of two subscribing Witnesses.

JOHN L. LAY.
