FREDRIOK BORNTRAGER, OF ST. CLAIR, MICHIGAN.

ROAD-CART.

SPECIFICATION forming part of Letters Patent No. 439,858, dated'November 4,1890.

Application filed April 1, 1890. fierial No. 3461235. (No model.)

To all whom it may concern.-

Be it known that I, FREDRIOK BORNTRA- GER, a citizen of the United States, residing at St. Clair, in the county of St. Clair and State of Michigan, have invented certain new and useful Improvements in Road-Carts, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to new and useful improvements in two-wheeled vehicles; and the invention consists in the peculiar construction of the devices for supporting the seat and foot rest and of adjusting the seat vertically, and, further, in the peculiar construction and arrangement of the various parts, as more fully hereinafter described.

In the drawings, Figure 1 is a vertical central section through my improved cart. Fig. 2 is a rear elevation thereof. Fig. 3 is an enlarged side elevation of the heel of the shaft and heel-iron from which the spring is suspended.

A are the thills.

B is the axle.

G are the cross-bars of a road-cart of known and usual construction.

a b are the heel or thill irons for connecting the thill to the axle by means of the clip 0, the brace 01 forming a forward extension of the clip 0. The forward heel-iron a is of the usual construction; but the rear heel-iron 17, instead of following the heel of the shaft in the usual manner, has the vertical portion 6 and the inclined port-ion f, the upper end of which is secured to the thill by means of the bolt 9. The heel-iron b is provided with the series of notches h.

D is the spring of semi-elliptic shape, having the usual eyes at its ends, to which are pivotally secured the clevises E and in which engage the links F, which are engaged over the heel-irons b, and by placing these links in the notches in the heel-iron b the spring is suspended slightly in the rear of the axle and free to have a vertical or lateral motion.

G is a seat, to which are secured the seatbars I-I, connected together by the slats I. The seat is supported upon the spring D by means of the seat-supporting frame J, secured to the seat-bars at its ends and centrally connected upon the spring. The forward ends of the seat-bars are connected to the lower end of a C-spring K, which is secured at its upper end to the cross-barC and embraces it, as plainly shown in 'the drawings. It will thus be seen that the seat and seat-bars are supported directly upon the semi-elliptic spring D, and at the forward ends the seatbars are also supported upon the Csprings, so that any vibration of the thills will not be transmitted to the driver, but will be taken up by the action of the C-springs.

Itis evident that the height of the seat may be adjusted to different loads and to diflerent horses by engaging the links F in higher or lower notches h in the heel-iron. The clevis and the link are twisted so that they will not bind in the use of the vehicle.

What I claim as my invention is-- In a road-cart, the combination, with the axle and shafts, of the heel-irons a 12, secured to the shafts and extending below the axle in the front and rear, respectively, of the shaft, the brace d, the clip 0 integral therewith, forming a connection between the heel-irons and constituting an extension of the brace, the vertical extension e of the rear heel-iron having notches h in its edge, the inclined brace portion f, integral therewith and projecting obliquely forward and forming an extension of the extension e, having its forward end secured to the shaft, and a seat-supporting spring adjustably secured to the extensions e, substantially as described.

In testimony whereof I affix my signature, in presence of two witnesses, this 21st day of March, 1890.

FREDRIOK BORNTRAGER.

Witnesses:

F. STREIT, JOHN MAXWELL.
