Letters Patent No. 98,207, dated December 21, 1869.

:MPROVEMENT IN CARRiAGE-SIPRING-S.

The Schedule referred to'in these Letters Patent and making part of the same.

To all whom 'it may concern! Be it known that I, GEORGE W. Tnw, of Kansas City, in the-county of Jackson, and State of Missouri, have made certain new and useful Improvements in Springs for Wagons, Carriages, and similar vehicles; and I do hereby delare the following to be a full and true description thereof, reference being bad to the accompanying drawings, and to the letters of reference marked thereon.

This invention relates, principally, to the use of a wooden spring-bar, witha proper vstrap-iron, and a wire or similar seat-cord, whereon the wagon or carriage-body rests; and y The nature of this invention is in the manner in which said parts are joined, to produce a more simple and durable support than hitherto achieved,

To enable those herein skilled to make and use my said improved spring and support, I will now more fully describe the same, referring herein to the accompan ying Figure 1, as a side elevation; to

Figure 2, as a top plan and to Figure 3, as a sectional elevation, showing one of the usual forms in which my said improvements may be employed to support a bugg or carriage-body and seat.

The spring-bars A will be supported .on and connected with the usual wagon or carriage-frame, by attachment to the axles or to the connecting parts of said frame, in any desired manner, there being no especial form of frame necessary theretbr. Said bars A are placed longitlulinally on the frame, and extend beyond the same, curving at ends in nearly the form of a circular quadrant, as indicated in fig. 1.

Said bars will be made of some light and durable wood, (such as hickoryy) and bent to shape, the curved ends a being strengthened by suitable iron. straps B,

secured by screws'to the outer edges of the bars.

The bars A do not forma returning curve attheir outer ends, but terminate slightly above the point at which a vertical line is tangent to the curveof the ends a.

The straps B are forged,'to form grooved bearings 1'), about which the wire seat-cords G are passed.

The seat-cords are formed of wires laid parallel'to each other, and forming eyes a about the rest-grooves b, and-to retain the wires in close contiguity to each other, the wire-wrappings c are used, thus being a wrapping about each cord 0, close to the groove-rests b, to secure the cords in the groove-restsf The buggy or wagon-body D will rest directly upon the cords O, and connect therewith by staple-thimbles d.

In order to prevent longitudinal motion of the body D onthe cords O, a Wrapping, 0, will be placed cout-iguous to each thimble d, as indicated in fig. 1.

The wire cords G will bewell painted, to secure against rust, and, owing to their form and structure, they will adapt-themselves readily to whatever form of seat or body D is placed thereon, thus giving a secure support.

Owing to the form of the spring-bars A, the weight. or load resting on the Wagon-body D is transmitted, as a vertical pressure therein, produoing but a slight deflection of said bars A, but as the vehicle passes over obstructions, such as rocks or, ruts in roads, the vibration of the wagon-body will then be largely in a horizontal direction, and this vibration will be eased off, and the jar thereof greatly lessened by the action of said springs. And it is plain that said springs will I therefore ride easy, or with great elasticity, whether the weight carried in the wagon be light or heavy.

The wire cords 0 being drawn taut, Will, moreover, prevent any undue oscillation or pitching of the body D, when the vehicle is in motion.

The said parts may be readily repaired and readjusted or replaced, and by their simplicity and econo- .my in first cost of material used, form an elastic support of great durability and cheapness.

Having thus fully described my invention,

What I claim, is

The straps B, arranged with grooved bearings, 11, combined with the cords O, wrapped and otherwise formed, substantially as set forth.

In testimony of said invention, I have hereunto set my hand, in the presence of- GEORGE W. TEW.

CHARLES WHITNEY, EDWARD DUNSCOMB, Md.
