NITED STATES ATENT ()FFICEO ELIAS D. ROTH, OF FORT COLLINS, COLORADO, ASSIGNOR OF ONE-HALF TO A. H. PATTERSON, OF SAME PLACE.

VEHICLE-SPRING.

SPECIFICATION forming part of Letters Patent No. 337,791, dated March 9, 1886.

(No model.)

1" aZZ whom it may concern:

Be it known that I, ELIAS D. ROTH, a citizen of the United States, residing at Fort Collins, in the county of Larimer and State of Col- 5 orado, have invented certain new and useful Improvements in Vehicle-Springs, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to springs for light wagons; and the object I have in view is to provide springs which, when adapted to the wagon,willbe light and strong, and at the same time equalize the weight upon the body of the vehicle in the line of draft, so that said body will always set level without regard to the weight, whether it is central or front or back.

The peculiarities of construction and arrangement will be hereinafter fully set forth.

In the accompanying drawings,making part of this specification, Figure 1 represents a longitudinal section; Fig. 2, a bottom View; and Figs. 3, 4, and 5, sections of detached parts, which will be hereinafter more particularly described.

In the figures, A represents the body of an ordinary light drivingwagon, and B the seat of same. Around the interior bottom of the body is a frame composed of four bars, C and C, suitably secured together and to the body.

A A represent the axles, and M the ordinary perch with its braces.

I I represent side bars, there being two beneath the body on each side. To the inner ends of these side bars are secured metallic 3 5 plates J J. The plates J are constructed with two jaws at their inner ends. The inner ends of plates J are constructed to pass in between the jaws, where they are pivoted, as will be set forth.

D D represent rods, which pass down from beneath the seat, their lower ends passing in between the jaws of plates J J.

F represents a metallic rod, which runs beneath the body and crosswise of? it. The ends 5 of this rod pass through the jaws of plates J J, through the ends of plates J J, and through the lower ends of rods D D, securing and piv oting the several parts together. The rods D D are surrounded by two coiled springs, one

within the other, one being smaller and of less tension than the other.

G represents the large spring, and g the smaller one. The rods D D pass through the longitudinal bars C, and also through a metal plate, H, upon said bars. The springs Gand 9 rest upon the plates II.

E represents a flanged metallic cap, which rests over the upper ends of the springs. The upper ends of rods D D pass through these caps, and are provided on these upper ends with threaded nuts (I d, for the purpose of regulating the tension of the springs. The bars I I are pivoted,as seen at S S, to the under side of the body. This is effected by means of plates having ears which are connected orsecured to the bottom of the body, and plates upon the bars having tongues which pass between the ears, and there secured by suitable pivot-pins. Upon the outer ends of the bars I I are secured metal ferrule-tips Z l, which have slots or openings in them on their under sides.

K K represent the clips which secure the body with its bars to the wagon. These clips have upon their upper sides knobs or projec tions, which enter the recesses or openings in the ferrules Z I. These knobs have slots at in them,and through which pass the bolts an, to connect and pivot them together. Above the knobs are rubber blocks to prevent rattling. The slots in the knobs allow of an eudwise 8o movement when the springs are pressed down. The ends of the plates J and J are slotted, as represented in Fig. 5, and for the same purpose.

One great advantage of the mode of construction herein described is,that the body is always kept level longitudinally, whether the weight be in the center or at either end.

The side bars and springs may be placed upon the outside of the body for heavy wagons, if so desired; but as a general thing this is not preferable. The tension of the springs may be regulated upon both sides equally, or. if more weight is to be carried upon one end of the seat, they can readily be adjusted to suit the weight by means of the nuts on the rods. The inner spring will support the load upon the seat when light-freighted; but as the load is increased the outer and heavier spring will assist in carrying the burden. f

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. TheplatesJ J, constructed at their-inner ends and slotted, as described, in combination with the cross-bar F, bars I I, the rods D 'D, and springs surmounted with cap E, substantially as and for the purpose specified.

2. The side bars, I I, having plates J J secured to their inner ends, and provided at their outer ends with recessed ferrule-tips, in combination with the clip K and its slotted bination with the adjusting-rods D D, caps E E, and plates J J upon the side bars, sub- 20 stantially as and for the purpose set forth., I z In testimony whereof I affix my signature in I presence of two witnesses.
