IMPROVEMENT |N THILL-COUPLINGS.
Specification forming part of Letters Patent No. 143,596, dated October 14, 1873; application filed August 7, 1873.
lings of Carriages, OfWhich the following is a specification To prevent the rattling Of thill-couplings it is-usual to insert in the same a rubber block or spring, concave on the front side, Which, as
usually made, has very little elasticity; and
the Objectof my invention is to make a spring which will have greater elasticity, and m'll more easily admit the insertion of the thill-iron in its place, than any spring heretofore made.
Figure 2 is a drawing of myspring, and I make the same of any desired size, with the sides, and ends fiat, and preferably rectangular, though the side nearest the axle may be the largest, and With the circular perforation b through the center of the same, as shown in the gure.
As thus made, the thinnest and most flexible part of the spring is in the middle of its sides, On a line parallel with the perforation b. When the spring is put in the coupling, and is pressed upon by the circular end of the shaft or thill iron, it becomes concave on the front side, and conforms to the curvature of the thill-iron. The upper and under sides become convex, and the perforation b becomes elon- Vitnesses:
