VEHICLE-SPRING.-

SPBCIPICATION forming part of Letters Patent No. 338,072, dated March 16, 1866. Application filed August 10, 1885. Serial No. 173,940. (No model.)

To aZZ whom it may concern.-

Be it known that I, ELMER J. Hess, a resident of Cincinnati, Hamilton county, State of Ohio, have invented certain new and useful Improvements in Vehicle- Springs, of which the following is a specification.

The object of my invention is to produce a light spring of great elasticity which is'economic of manufacture. The spring is adapted for use with side-bar vehicles.

In the accompanying drawings, Figure 1 is a side elevation of my improved spring attached to the cross bar of a vehicle. Fig. 2 is a view of the under side of the same. Fig. 3 is a cross-section of the spring, (the crossbar being omitted,) taken alongside of one of the clips. Fig. 4 is a view in perspective of one of the blocks or pieces preferably used between the curved spring and the elastic plate hereinafter described. Fig. 5 is a view of the central portion of the spring, showing bolts as a means of connecting the curved spring to the elastic plate.

The cross-bar A is rigidly secured to the under side of the vehicle-body. Its lower surface has its central portion cut away, forming the recess A. The metal plate B extends across this recess, and is secured to the crosspiece A by the bolts d. Between each end of plate B and the adjacent part of the cross bar A or vehicle-body a piece of rubber is preferably placed to form an easy and elastic seat for the spring-plate B; but the presence of this rubber is not essential to the operation of my spring. An alternate arrangement consists in providing projections from the face of the cross-piece A, or equivalent portion of'the vehicle, to which the plate B may be attached, dispensing in this way with the recess A. The device as illustrated is of the preferred form.

The spring 0 is attached to the plate B by the clips 0 e. The spring 0 is sometimes made of a single piece of metal, 0; but it is preferably re-enforced by leaves 0 C in the usual way. These leaves may be connected together in any of the well-known ways. A bolt, f, is preferably present to secure them together at the middle portion of the length of the spring (1. The ends of the bottom or long leaf of the spring are curled upward for attachment to the side bars at g.

The spring is not always attached directly to the plate B, but preferably as follows: Two blocks, M M, preferably V-shaped or rounded, are inserted between the plate B and the spring 0. The ends of these blocks M extend slightly beyond the edges of the spring 0, and into them are cut notches m, down to the edge of the spring. (See Fig. 4.)

Clips 0 e are used to secure the spring to the plate B. These clips fit in the notches m and pass under the spring. The ends of the clips pass through the plate B, and are there provided with nuts, which, when tightened, hold the spring firmly in place.

In Fig. 3 is shown the means which maybe employed, when found necessary, for preventing the spring from slipping longitudinally. A tongue, e, projects upwardly from each clip e, and fits into a corresponding opening, (2, in the under side of the spring 0. (See Fig. 3.) This tongue prevents the spring slipping longitudinally. When preferred, bolts passing through the spring 0, blocks M, and plate B may be used in place of the clips 6. (See Fig. 5.) In such event the notches m will be unnecessary.

The sharp or more pointed side of the blocks M may either bear against the plate B or the spring 0, the latter being preferable. The blocks increase the opportunity of the spring 0 to bend, and in this way increase its elasticity. The plate B is also of great service in increasing the elasticity of the spring. It should be observed that the recess A is sufficiently deep to prevent the heads of the clips 6 from striking against the cross-piece A.

The whole device is a light, easy working spring of great elasticity.

Vhile the various features of my invention are preferably employed together, one or more of said features may be used without the remainder; and in so far as applicable one or more of said features may be used in connection with springs of a description other than the one herein specifically set forth.

\Vhat I claim as new and of my invention, and desire to secure by Letters Patent, is-

1. The combination of the vehicle body or support, elastic plate B, secured at its ends thereto, space Aabove the middle portion of said plate, and continuous spring 0, connected to said plateB by clips (2 e directly beneath said space A, and at the middle portion of the latter, substantially as and for the purposes set forth. y

2. The combination of thevehicle body or support, elastic plate B, secured at its ends thereto, space A above the middle portion of said plate, continuous spring 0, connected to said plate B by clips 0 e directly beneath said space A, and at the middle portion of the latter, and bearing -blocks M, provided with notches m, substantially as and for the pur- I poses set forth.

3. The combination of the plate B, spring O, bearing-blocks M, provided with notches m at the ends, and clips e e, fitting said notches, substantially as and for the purposes set forth.

4. The combination of the plate B, spring 0, bearing-blocks M, provided with notches m, and clips 6, provided with-tongues e, fitting corresponding recesses in the spring, substantially as and for the purposes specified.

ELMER J. HESS.
