- my invention consists in preventing the sudden collapse of the common elliptic spring by the inverse point giving elasticity to the outer elliptics, thereby rendering them less liable to bend or break.

WILLIAM SHARP, OF BURDET'I, NEW YORK.
IMPROVEMENT IN CARRIAGE-SPRINGS.
Specification forming part of Letters Patent No. 682, dated April 7, 1838.
I To all whom it may concern:
Be it known that 1, WILLIAM SHARP, of Burdett, in the county of Tompkins and State of New York, have invented a new and Improved Mode of Making Springs for Carriages; and I do hereby declare that the following is a full and exact description of the same, reference being had to the annexed drawings of the same, making part of this specification.
The nature of my invention consists in preventing the sudden collapse of the common elliptic spring by the inverse point giving elasticity to the outer elliptics, thereby rendering them less liable to bend or break.
To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.
I construct a spring three feet long by taking a piece of steel A, Fig. 1, five feet eight be bent in the form of an ellipsis. Thus one half of the spring is formed. I then make the other part B in the same manner, and
then either bolt or rivet the inverted points C together. Thus the spring is formed, the rule to be varied according to the length of the spring required. In order to double the strength required, I propose, also, to make an inside spring D, Fig. 3,i'n the same manner as the other, only shorter and smaller, so as to operate on the inside of the other, being fastthe accompanying drawings, in combination as above.
WILLIAM SHARP.
