Letters Patent No. 109,095, dated November 8, 1870.

IMPROVEMNT IN SPRINGS FOR VEHICLES.

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

'I, ENOS l/VRIGHT, of the county of Lee and State of Iowa, have invented certain Improvements in the Mode of Applying Springs to "ehicles, of which the following is aspecifieation;

-Nat'u-rc and Objects of the Invention.

The first part of my invention relates to the construction of a spring bearer, in such' a manner that its upper side shall be attachable to the under side or bottom of the body of the vehicle, and its 'under side shall fornr a curve, which may be the are of a circle, or vary somewhat from it, as the case may be, and around which curve the'spring, which is attached to said bearer at or near the center of both spring and bearer, shall bend, touchingand resting'against said bearer, from the center'or point of attachment, toward both endsfjust in proportion as the weight of the load is increased, thus causing the spring to adjust itself to theweight of the load, and to be pliable with either a light or heavy load.

The second part of my invention relates to the construction and combination with the spring-bcarer-sand springs, ofspring-holders or couplings, roller'boX es and-rollers,'and rub-irons and plates, in such a inanner that they may be applied to all kinds or" vehicles.

Description of the Accompanying Drawing.

Figurc'l is the body of a lumber-wagon, with spring-bearer and spring attached.

Figure 2 is a bolster, containing roller-boxes and rollers, and towhich wearing-plates are attached.

Figure 3 is a roller-box.

Figure 4 is a roller,

General Description.

A is body of lumber-wagon, with spring bearer, spring, and spring holders attached. I

B is the spring bearer, which is'made of wood, and is of a thickness tocorrespond with the ,width of spring, and of a suflicient depth ,tovgive. as much spring room between endsof spring and underside of wagon-body, as isdesired. f

Said bearer is connected, with the wagon-body by bolts 1 1 1 1. I

O is the spring, and is a single bar, either of wood or steel, and is connected with the bearer by bolts, 2 2.

1) I) are the spring-holders, and are made of iron,

the object of said holders being to hold the spring,

being secured to the under side of the same by bolts, .33 L5 3, to form a connection with the running part of wagon, by resting at points directly beneath D 'D,

on rollers, in the top of bolsters, shown by E Ein fig. 2; and also to hold the wagon-body from sliding back and forward, bythe perpendicular part of the holders at 4 4 coming in contact with the side of the brfli ters at points 5 5, in fig. 2, and to which points wearing-plates are attached, to prevent wearing by the. holders, into the sides of the bolsters.

, 6"6, in fig. 1, are wearing-plates, to prevent the bolster-stakes 7 7 from wearing into the sides of the wagon-body.

8 is therub-iron, for the wheel to rub against when the wagon is cramped, as in turning, and is connected with the bearer by the points at the upper end being turned at right angles and driven into it.

. Fig. 3 is box, made of cast-iron, and is sunkin the top of the bolster at E E, the object of the box being to form a firm cavity or trench for the roller to work in.

Fig.4 is a roller, which is of iron, and is of the right length to drop easily into the roller-box lengthwise with the b'olster, but it must not have room enough to work much in that direction, and must be of suflicient diameter to fill about two-thirds the width of thcibox, and to rise about one-fourth of its diameter above the top or upper surface of the bolster, the

7 box being of proportions suitable for the purpose.

The object ofthe roller is to prevent wearing and friction by the holders on the top of the bolster.

The object of thesmall section, is

First, to show a difi'erent style oi finish of the bearer for light wagons and carriages.

Second, to sl1ow, by the spring attached thereto, on the end marked A, a different kind of holder from that hereinbet'ore described. Thiskind, though objectionable on account of raising the wagonbody higher, may be preferred by some on account of being cheaper, therefore I desire to have it included.

Third, on the end of said spring, marked B, is the ykind of couplings'uscd for light wagons and carriages.
