IMPROVEMENT'l IN SPRING-SEATS FOR WAGONS.

Specification forming part of Letters Patent No. 126,867, dated May 21, 1872.

Specication describing a certain Improvement in Spring-Seats for Wagons, invented by GEORGE W. BENNETT, of Avon, in the county of Livingston and State of New York.

My invention consists in an arrangement of springs made adjustable in the manner and for the purpose hereinafter specified.

In the drawing, Figure l is an elevation; Fig. 2, a bottom view; Fig. 3, an elevation, showing' a moditied form ofthe springs; Figs. 4, 5, and 6, detailviews.

A -represents the seat proper, which may be made otany desired form. B B are the springs, which are made of steel wire of suitable size. Each spring extends from end to end of the seat, so as to give the desired elasticity at cach end, and at the same time to be easily attached onthe under side. This attachment is made as follows: The central portions a a. of the springs are made arched or convex, and are secured to the center of the seat by a cross-piece, C, screwed fast in place. On each side of this are bolsters or bearing-blocks D D, through which the springs run loosely, bein g held thereto by metallic cleats b b, which are bolted inl place. The holsters are made adjustable forward or back by means of bolts e e, which enter a series of adjusting holes, c c, (Fig. 4,) in the seat, or longitudinal slats, which answer the same purpose. Outside the holsters the springs are bent into coils del, by which additional elasticity is obtained. In some cases Icontemplate attaching the ends of the springs directly to the bolsters, as shown in Fig. 3; said ends being b'ent up vertically, and passing into the loosely in their passages in the rail-bearings, so 'as not to interfere with the adjustment. By this arrangement it will be seen that a double adjustment is attained: First, by moving the holsters D D nearer together or further apart a vertical adjustment of the springs is produced,which elevates or depresses the sea-t. Second, by screwing up or back the nuts g g o n the outer springs, the railbearings are moved toward or from each other, which adapts the saine to fit wagon-bodies of diiferent widths. One adjustment is essential to the other, even in the same wagon, since the vertical raising of the seat to insure a greater stiffness to accommodate a greater load will require the letting out of the rail-bearings and the reverse. This arrangement of the springs having the double adjustment described, Ibelieve to originate with myself.

Another feature of novelty consists in malring the length of the springs inthree divisions, the central on e, a a., of which is made stiff and u-nyieldin g, thereby securin g firmness of attachmen t, while the other arms form the springs proper. The central portion aby bein g arched,

ment toward and from each other, and the railbearings have an adjustment on the springs, as and for the purpose specified.

In witness whereof I have hereunto signed `my name in the presence of two subscribing GEO. W. BENNETT.
