GPECIFICATION forming part of Letters Patent No. 349,960, dated September 29, 1886, Application tiled Augnsttl, 1886. Serial No. M0387. (No model.)
To aZZ whom, it may concern:
Be it known that I, BRYANT A. TREAT, of Wallingt'ord, in the county of New Haven and State of Connecticut, have invented new Im p rovements in Vehicle-Springs; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which'sa-id drawings constitute part of this specification, and represent, in-
Figure 1, a side view of the axle and spring complete, the central portion being broken away to contract the figure; 'Fig. 2, a top view showing one auxiliary spring and. a portion of the principal spring.
This invention relates to an improvement in that class of carriage-springs in which downward bends are made in the axle, so that the spring may hang within the bends. In the more general construction of this class of axles an ear is attached to or made a part of the axle at the bend, and extends inward so that the spring is hung directly to the car at each end. This shortensthe spring to an undesirable extent.
The object of my invention is to retain the low-hung spring but increase the elasticity; and it consists in fixing upon the axle at each end an auxiliary spring, each of which extends inward, combined with a spring hung by its two ends to the respective ends of the said auxiliary springs, as more fully hereinafter described.
A represents one arm, and B the other arm, of the axle. For a short distance inside the arm the axle is straight, as at O. The axle is there bent downward or "cranked to the required extent, as shown, and as in the usual construction of this class of axles.
D D are auxiliary springs. These springs are constructed with a foot, E, fitted upon the straight part of the axle and there secured. The foot may extend down the bend to aid in securing, if desired. From the arm endof the respective feet the spring is curved upward and inward and then downward, terminating in an eye. F, or other device, by which the applied at that point of the axle, instead of within the bend, as in previous constructions. Therefore not only is the elasticity for the carriage greatly improved, but the axle is to a great extent relieved from the tendency to swing.
I am aware that carriage-springs have been constructed consisting of a principal half-elliptic spring with a curved auxiliary spring at each end, each auxiliary spring fixed to the axle independent of the principal spring, and the free ends of the auxiliary springs hung to the respective ends of the principal spring; but in such previous construction the bearing of the auxiliary springs has been at a point considerably inside of the end of the axle and substantially below or inside of the ends of the principal spring, whereas in this invention the springs start close to the axle-arm and take their bearing at that point, so that the load is supported wholly at that point. Thence the springsare curved upward, inward, and downward to meet the ends of the principal spring.
I claim The combination ofa crank or downwardlybent axle, a principal spring, G, lessin length than the distance between the bends of the axle, and an auxiliary spring, D, resting upon the straight part of the axle and starting substantially at the collar, curved upward, inward, and downward into the bend of the axle, the principal spring G hung by its respective ends to the free end of the said auxiliary springs D, substantially as described.
