IMPROVED SUPPORT ron ELLIPTIC' srmn'es The Schedule referred to in these Letters atent and making partof the name.

Be it known that I, JOHN J. Usswon'rn, in the city of Washington, in the District of Columbia, have invented a new and useful Improvement in Elliptic Springs for Carriages andother Vehicles of similar character; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

-It consists in the spring 0, the guide or clutch d and d, and the standard it, with receptacle therein, for the rubber, f, and sprin'g G, as also, obviously, in the peculiar construction and arrangement of the parts aforesaid. I I

In the drawings- 1 Figure 1 represents a longitudinal view.

Figure 2 represents a front view.

.Similar letters of reference indicate likeparts.

My improvement in the construction of elliptic springs for carriages, and other vehicles of similar character, is designed to strengthen said springs, and to render them more elastic, andalso less liable to be broken by heavy jolting, or the swaying of the we hicle. consequent thereupon.

A represents two pieces of steel, which comprise the ordinary elliptical spring, the same, being riveted together at the extremities thereof, as shown at a.

B is a wooden bar, which is' screwed to the ellipse, the screw projecting from the interior of the said ellipse,-throngh the wooden'bar, the bar havinga small .rnetallic plate, 11, located thereon, upon which the end of the screw is riveted.

O is-a steel spring, which is screwed to the perch R at c, and to the ellipse. Saidspring passes through the nietallic standard 8 and over the rubber provided in the-aperture of said standard, and thence immediately over the elliptic spring A, which it overlaps with a flange, d, .p vided or formed thereon. And the piece 11, also provide with a flange, and riveted to the spring 0, comprises, together'with the flange d,a guide or clutch for holding the elliptic spring, and causing it, when vibrated, V

to move vertically.

S represents an iron standard, the upper part of which is quadrilateral, and, from the perch downward, a screw. The screw-portion thereof projects through a suitable aperture in the perch R, and is secured thereto by the nut e.

Said iron standard has an aperture, f, formed therein, within which is firmly secured a piece of rubber, which latter is a few lines smaller at the upper part thereof than the aperture formed for its reception, in order to admit above it the steel spring 0, which is caused to rest or impinge thereon, as aforesaid.

1t represents the perch, which is not of peculiar construction, but of such construction as ordinarily obtains in the aforementioned vehicles, excepting that the elliptic spring is screwed to itat m, and the longitudinal. spring at c, and that the screw of the iron standard S projects through it, and is fastened thereto by a nut, c. e

' I Claim.

The longitudinal spring 0, provided with clutch d and d, for grasping the elliptic springA, and the metallic stand ard S, provided with an aperture, and rubher located therein, the whole being constructed, ap-

plied, and arranged to operate in conjunction with elliptic springs, substantially as specified.
