AUGUST SOHUBERT, OF ONEIDA, NEYV YORK.

SPRlNG-VEHICLE.

SPECIFICATION forming part of Letters Patent No. 378.180, dated February 21, 1888.

Application filed September 7 1887. Serial No. 249,007. (No model.)

To all whom it may concern.-

Be it known that I, Anousr Sennsnnr, of Oneida, in the county of Madison, in the State of blow York, have invented new and useful Improvements in Spring-Vehicles, of which the following, taken in connection with the ac companying drawings, is a full, clear, and exact description.

This invention relates to the class of springgears usually designated duplex spring, in which two springs are arranged respectively at opposite sides of and parallel with the axle.

The invention consists in supporting the springs on the axle by means ofspringarlns secured to the end portions ofthe axle and stand ing lengthwise thereof and couplings connecting the ends of the springs to the vibratory ends of the springarms. Said combination and arrangement of parts constitute a duplex spring-gen r which is compact, simple, and comparatively inexpensive, and affords increased elasticity without inducing lateral swaying of the body of the vehicle.

The invention is fully illustrated in the annexed drawings, in which Figure 1 is a front elevation of a springgear embodying my improvements. Fig. 2 is a top plan view of the same. Fig. 3 is a transverse section on line :10 :1:,Fig. 2. Fig. 4 is a vertical longitudinal section on line y 9 Fig. 2. Fig. 5 is a detached top plan view ol'onc ot' the spring-arms. Fig. (l is a side elevation of a modification of the spring-arm, and Fig. 7 is an end view showing a modification of the spring'coupling.

Similar letters of reference indicate correspending parts.

A represents the axle, which is preferably formed with the downwardlydeliected portion A A. On the end portions of this axle I mount spring-arms C (l, which stand in the direction of the length of the axle and are preferably secured to the top of the downwardlydellected portions A A of the axle by clips c e,cn1bracing the said axle portions and superincumbent attaching ends of the spring-arms ()0, as illustrated in Fig. 1 of the drawings, the free or vibratory ends of the spring-arms rising outward from the aforesaid portions of the axle. in order to prevent the spring-arm C from slipping longitudinally on the axle, I provide the top of the latter with a recess, b, into which projects either the bolt or head of the bolt which fastens together the leaves of which the spring-arm is composed, as illustrated in Fig. 4 of the drawings.

The free end of the spring-arm G is formed with a lateral flare, c, and with an eye or sleeve, a, across the flare, and on opposite ends of said eye are hung the springs D D, which are arranged at opposite sides of the axle and terminate with the usual eyes for the reception of the bolt by which they are coupled to the two spring-arms O O. The connection of the springs D D with the spring-arm G, I prefer to make by placing the eyes of thesprings D D in range with the eye a of the spring-arm and close to the ends thereof and extending the couplingbolt through the three eyes, as represented in Fig. 3 of the drawings, and on heavy vehicles I re enforce the said coupling by mounting on top of the eye a a saddle, It, which projects over the eyes of the springs D D and terminates with perforated earsrl tat the outersides of the springeyes and receives through said ears the ends of the bolt which couples the springs D D to the spring-arm, as illustrated in Fig. 7 of the drawings. Ido not, however, limit myself to any specific coupling devices, as the same admits of many modifications.

It will be observed that when the spring arms G G are arranged on the downwardly-deflected portions AA of the axle, as shown in Fig. 1oi'thedrawings,thespring-anns,when depressed, are brought to bear on the axle nearer the oscillatory ends of the springarms, and thus the supports of said arms are re-en forced in accordance with the increase of the strain applied to them.

Although I prefer the arrangement of the springarnis G G, as before described, yet I do not wish to be limited in this respect, inasmuch as it admits of many modificationsmne ofwhich is illustrated in Fig. 6 ofthe drawings,in which the spring-arm C is placed reverse from the position hereinbefore described, and is rigidly mounted on the horizontal end portion of the axle. The springs D D may be connected to this spring-arm in the same manner as shown in Fig. 3 of the drawings.

Having described myinvention,what I claim as new, and desire to secure by Letters Patent, is-

1. The combination of the axle A, formed with the downwardly-curved portions A A,
