VEHICLE-SPRING.

SPECIFICATION forming:y part of`Letters Patent No. 393.297, dated November 20, 188.

Application filed June 5, 1888.

To all whom. it may concern:

Be it known that I, ALBERT CLARK, a citi- Zen of the United States, residing at Lansing, in the county of Ingham and State of Michigan, have invented certain new and useful Improvements in Vehicle-Springs, of which the following is a speciicatiomreference being had therein to the accompanying drawings.

r[lhis invention relates to new and useful improvements in vehicle-springs, and the invention consists in the peculiar construction of a spring and its combination with the runninggear and body ofa vehicle, all as more fully hereinafter described.

In the drawings which accompany this specification, Figure l is a perspective View illustrati n g n'iyin'iproved Vehicle-spring as applied to the so-called buckboard 7 vehicle, and Fig. 2 is averticai central longitudinal section thereof.

A are the springs, B is the wagon-body or buckboard, C is the front axle, and D is the rear axle, of a vehicle. The springs support the fourcorners of the buckboard in the longitudinal direction of the body, one pair supporting the front end upon the front bolster in advance of the buckboard and the rear pair supporting it upon the rear bolster in the rear of the buckboard to permitafree vertical play of the buckboard between the front and rear axles.

Each spring consists of one or more leaves bent in the form of a volute with the inner end of the volute formed into an eye, and with the outer end of the volute forming a lateral straight extension. These springs are secured at each end of the body by means of suitable bolts, ct, as shown, and with the volute circling around the bolster to bring the eye of the volute on top, where it is secured by means of suitable clips,preferabl y consisting of the plate b, formed integral with the ears c upon its upper side, and secured to the bolster by means of the clip-bolt d. 1

By making the lateral arm of the springs shorter or longer any desired elasticity of the ,springs may be obtained. At the same time this construction has several advantages above others now known for ordinary vehicles, as it Serial No. 276,006. (No model.)

will be seen that there is a greater play of the body under heavier or lighter loads, while at thesame time the working out of the pivotal pin securing the spring to the bolster will not produce any accidents of a serious nature, as the spring remainssupportedupon the bolster. It is also very hard to break aspring of this construction, as under a great depression or load the longitudinal play of the body is stopped by the bolster, and therefore cannot bring any longitudinal strain on the spring. I deem the relative position of the body and bolsters important, for by this arrangement the body can freely play between the bolsters under heavy loads, and thus very easy riding is the result.

\Vhat I claim as myinvention isl. The combination, with the front and rear axles and the bolsters thereon, of the body or buckboard of less length than the distance between said bolsters, the volute springs secured at one end directly to said body or buckboard near the ends thereof,and the other ends passed under the bolsters and turned upward in front of the front board and in rear of the rear board of said body, and with the eyes thereof supported on top of said bolsters, substantially as and for the purpose specified.

2. The combination, with the front and rear bolsters, the body or buckboard B, of less length than the distance between said bolsters, and arranged between said bolsters of the volute springs A, secured direct-ly to the front and rear corners of the body in the longitudinal direction thereof and passed under said bolsters, of clips consisting of the eared plates b, secured to the eye of the spring on top of the bolster, and the clip-bolts d, the parts being arranged and constructed substantially as and for the purpose described, whereby the body has a free vertical play between the bolsters, as set forth.

In testimony whereof I affix my signature,in presence of two witnesses,this 4th day of January, 1888.

ALBERT CLARK.
