CARRIAGE-SPRING.

SPECIFICATION forming part of Letters Patent N0. 233,727, dated October 26, 1880 Application Bled September 1, 1880.

1'0 all whom t may concern:

Be it known that 1, SHErARD YV. CATELY, aI citizen of the United States, residing at the village of Cortland, in the county of Cortland and State ot' New York, have invented certain new and useful Improvements in Carriage- Springs; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to whichitappertains to make and use the same, reference being had to the accompanying drawings, and to the letters ot` reference marked thereon, which form a part .of this specification.

My invention relates to the construction of auxiliary carriage-springs wherein the recoil motion of the springs is regulated and controlled; and it consists in the employment ot a spring composed ot as many leaves as necessary to impart to it the strength and rigidity required for the use intended, and located immediately in the rear ofthe axle, as more fully hereinafter specified.

lt is a well-known fact that all carriagesprings, as heretofore made, are stronger to resist the weight ot a load bearing down than to withstand the momentum of the recoil from a sudden depression ot' the springs. My invention obviates this difficulty, moderating and governing the recoil movement, and thus preventing breakagcs of the springs and carrying the body of the vehicle more steadily over rough and uneven roads. These objects I attain by the mechanism illustrated in the accompanying drawings, in which- Figure l represents a top-plan view of my improved invention Fig. 2, an end View, and Fig. 8 a horizontal sectional view.

.The letter A indicates the side springs, and B the connecting-spring, ot' an ordinary platform-sprin 0'.

(l indicates the axle, and D and E are two spring-bars which support the body of the vehicle.

The letter F indicates an auxiliary semi- (No model.)

elliptic spring, composed ot as many leaves as may be necessary to .impart to it the strength and rigidity required for the use intended. Said spring is located, asshown, immediately in rear of the axle C, and connected at its extremities to the side springs, A, by clips or fastenings a and at its central convex point to the spring-bar D. Theleaves of the spring F are iirmly secured together at or near the extremity ot' each crowning-leaf by means of metal clasps or bands b, thus strengthening and giving to the spring a rigidity nearly equal both in direct depression and recoil movement. rlhe extremities ot' the spring F, when secured to the clips or clasps a, are drawn from their natural. position when at rest, as shown by dotted lines xx, so as to create a constant tension in said spring, which is imparted to springs A B, slightly depressing the bodyot' thevehicle toward lthe springs.

My invention is not limited in its applica-v tion to platform-springs, but maybe used with other styles, whether side or end springs, in each case having its connections adapted to the peculiar style and construction of the vehicle.

Having thus described my invention, what duce a constant downward tension upon thc side springs and to resist the recoil movement `of the vehicle-springs, as specified.

1n testimony that I claim the foregoing as my own l have hereto affixed my signature in presence of two witnesses.
