Letters Patent No. 100,444, dated March 1, 1870.

IMPROVED SPRING- SEA'I' FOR WAGONS.

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

To all whom itmay concern.-

Be it known that I, WILLIAM Pnun'r'r, otlJuquoin, in the county of Perry, and in the Stateof Illinois, have invented certain new and useful Improvementsin Spring 9 Seats for Wagons and other Wheeled Vehicles; and

.I do hereby declare that the followingis a full, clear,

and exact description thereof, reference being bad to the accompanying drawings and to the letters of ref- "erence marked thereon.

The nature of myinvention consists in constructing a wagon or carriage-seat with such a combination of springs made of \vood,-and arranged with hinges and braces, as will be strong, durable, and cheap, at the same time light and elegant, giving ease to the driver,

and supplying a want long experienced, all of which will now more fully appear in the description, toenable those skilled in the volition.

' In. the'drawings-- I Figure l is aii'ont elevation, and.

Figure 2 is an under-side view of my-inrention; and

Like letters indicate like parts in the two figures.

A represents an ordinary can'iage or' wagon-seat, on the under sideof which the ends a of the springs B are secured by bolts, screws, or other suitable means.

The opposite ends I) pf the springs are secured in cross-ties 0, one of which is under or below the right andthe other below the left end of seat A, (see fig 1.) There are four of these springs 13, as will be more clearly pel't rii'ed in fig. 2.

Each ofthese springs is composed of two pieces of art to make and use my inwo'od, indicatedby the figures 1 and 2 in fig. 1, which are united by means of a hinge, D, by means of which greater freedom in theplay of the spring is secured. Each springhas a brace, E, secured by one of its ends to'end a of the spring, and secured by its other end near the middle of lower piece, marked 2, of the spring, by means of which brace E greater stiiiness is secured, and the action of the weight of the driver is thrown upon the spring in more'equable proportions;

and it will be seen that the upper partonpiece, marked 1, of each 'of the springs that is attached by its end a to the bottom of the seat, has its elasticity at the end to which the hinge is attached, while the lower part, or piece marked 2, by means of the upright brace E, has a double elasticity, bending upward at each end as a bow is bent, through the brace E acting as a fulcrum, on whiclrthis piece marked 2 is bent by the direct pressure of the drivens weight on the center of piece 2 transmitted by said brace E. Thus it will be perceived that the braces E give much greater elasticity, and shorter sweeps? to the springs than they would have if the braces were not used.

By proper strength being given to the materials used, by increase of thickness or stoutness, I may find that only two springs are necessary in light buggies.

Having thus fully described my invention,

\Vhat I claim as 'new, and desire to secure by Letters Patent, is-

1. The wooden spring B, composed of the pieces 1 and 2, braces E, and binge D, pieces 1 and 2 attached respectively to the seat A and the braces E, substantially as and for the purposes set forth.

2. The braces E attached to pieces 1 and spring B, in the manner described, and operating as and for the purposes set forth. x

In testimony that I claim the above-described certain new and useful improvements in spring seats for wagons and other wheeled vehicles, I have hereunto signed my name this 26th day of November, 1869.

WILLIAM PRUETT. Witnesses: r TOM O. Warmers,

L. P. PARKER.
