VEHICLE-SPRING.

SPECIFICATION forming part of Letters Patent No. 448,543, dated March 17, 1891.

Application filed August 5, 1890- Serial No. 361,036. (No model.)

To all whom (it 1m concern:

Be it known that I, GEORGE E. RAYMOND, a citizen of the United States, residing at the city of Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Vehicle- Springs, of which the following is a specification.

This invention relates to the arrangement of one or more springs between substantially parallel equalizing-bars, said springs being supported directly from said bars upon supports placed intermediate the bars which connect the equalizing-bars with the side rails of the vehicle.

The objects of the invention are to produce a cheap and effective spring connected to the vehicle-body, so as to produce an elastic equalizer which is not wholly rigid, but which will allow a sufficient quantity of lateral movement to give an easy movement to the vehicle-body, and at the same time to produce an equalizer that will cause all parts of the vehiele-bod y to descend whenever pressure is applied to any one part; also, to combine a spring with arms in such a manner that in case of breakage or other defect of the spriu g the same can be readily repaired at a small expense These objects I accomplish by means of the mechanism illustrated in the accompanying drawings, in which- Figure 1 represents an inverted plan view of a vehicle-body with my improved spring attached. Fig. 2 shows a modified form of the same. Fig. 3 shows an end view of the spring and sections of equalizing-bars, and Fig. 4 shows a preferred form of the arm which connects the equalizing-bar to the side rail.

Similar figures refer to similar parts throughout the several views.

5 5 represent the side rails connected to the vehicle-body in any suitable manner.

8 8 represent arms connecting the side rails to the equalizing-bars 3 These equalizingbars are supported by suitable journals shown by 7 7 7 7. These journals, in the example of my invention illustrated in the drawings, are attached to thecross-pieces 6 6.

1 represents the spring, which may be duplicaied, as shown in Fig. 2, if desired. This spring is a coiled spring, having projections engaging with the arms 2 These arms 2 2 are connected to the equalizingbars rigidly at a point intermediate the connections between each equalizing-bar and the outwardly-extending arms 8 8. This arrangement or position of the arms 2 2 allows for the use of the spring 1, which is comparatively short, and the length of the coil may be increased or decreased, provided it extends only from the arms 2 2, which, as above stated, are placed intermediate between the connectingpoints of the arms 8 8 with the equalizingbars. The spring 1 is entirely supported by the arms 2 2, and has no connection with the body of the vehicle except through said arms. This arrangement allows for the free movement of the body and compels the spring to substantially support the same.

\Vhen greater elasticity is required, the springs may be duplicated, as shown in Fig. 2, although for ordinary purposes I believe the form shown in Fig. 1 is preferable.

The outwardly-extending arms 8 8 may be either from the inner side of the cross-pieces 6 6, as shown in Fig. 1, or from the outer side, as shown in Fig. 2, and the inner arms 2 2 may, if desired, be made integral with the extension of the spring.

Having thus described my invention, what I claim to have invented, and desire to se cure by Letters Patent, is

In combination with the body of a vehicle, a coiled spring arranged between two substantially parallel equalizing-bars, arms connecting the said coiled spring to said equalizing-bars by rigid connections, journals supporting the equalizing-bars and connected to the vehicle-body, and arms extending outwardly from the said equalizing-bars and connected to the side bars of the body, each of said arms which connect the spring to the equalizing-bars attached to said equalizing-bars at a point intermediate the connections between said equalizing-bars and the outwardly-extending arms, all substantially as and for the purpose described.

In witness whereof I have hereunto set my hand and seal in the presence of two witnesses.

GEO. E. RAYMOND.
