VEHICLE-SPRING.

. SPECIFICATION forming part of Letters Patent No. 274,880, dated March 27", 1883.

Application filed Decemher 14, 1882. (No model.)

To all whom it may concern:

Be it known that I, CHARLES U. BISHOP, a

citizen of the United States, residingat Nashville, in the county of Davidson and State of Tennessee, have invented certain new and use- I ful Improvements in Vehicle-Springs; and I do declare the following to he a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had'to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specifica tion.

This invention relates to an improved form of vehicle-spring, as hereinafter described and claimed.

In the annexed drawings, illustrating this invention, Figure 1 is a plan view of my improved vehicle-spring. Fig. 2 is a side elevation of the same applied to the axle and body sill, and Fig. .3 shows the two parts of the spring disconnected. a f

. Like letters indicate like parts.

The spring is made in two parts, A A, one

1 of which is secured to the body-sill and the other to the axle .or head-block. Each part of the spring is composed of any suitable number of leaves andre-enforcing plates.

It will be observed that the springs A A are bent laterally and toward each other, this bend being made in the center of each spring, as shown in Fig. l.

It will also be observed that the lower spring, A, is curved upward from its central portion, which is secured to the head block or axle, while the upper spring,A, is curved downward from its central portion, which is secured to the body-sill, the ends of the upper spring bein g passed beneath the ends of thelower spring and secured thereto by any suitable means. Heretot'ore an elliptic spring has been made in two parts arranged outoi' verticalrange, the

upper and lower sections or parts being paral-' lel and bent or providedw'ith offsets at their ends, which are connected byordinary bolts or rivets, the ends of the upper spring being passed undertheendsofthelowerone. Springs of this character-that is, having their bodies 6 parallel and being bentlaterally only at their ends-will twist the bolts or connections, thereby exerting excessive strain thereon, so as to cut and break the same, the leaves of such strain to which they are subjected. It is obvious that unless the parallel portions of the to come in contact at their edges when the vehicle is in use. These difficulties are entirely overcome and a spring of great elasticity and durability is produced by bending them in the axle, or head block where there will be no strain, the remaining portions of the spring being perfectly straight, as shown in Fig. 1.

In order to enable the springs A A to be properly connected, their ends are beveled, as shown in Fig. 3. The upper spring, A, is providedat each end with an eye, a, that is received between lugs b b on the lower spring, a bolt, rivet, or other suitable connection being used to unite the parts.

By referring to Fig. 1 it will be seen that the central portions of the springs A A, instead of being parallel, are disposed so as to leave a diamond-shaped space that prevents interference between the two parts or halves. It is obvious that this construction enables the re'enforcing plates of either spring to be carried nearer to its ends than is possible where the bodies of the springs are made parallel and provided with ofl'sets. My springis therefore much-stronger, possesses more elasticity, and is more easily adjusted than any springs of similar character.

Having thus described my-invention, what I claim as new, and desire to secure by Letters Patent, is-.

. A vehicle -spring composed of two parts, bent laterally in straight lines from their central portions, the ends of said parts being beveled, whereby the ends of the upper spring are passed beneath and secured to the ends of the lower spring without strain or injury to the bolts or connections, substantially as described.
