BENJAMIN F. BOWMAN, OF BERKELEY, CALIFORNIA.
VEHICLE-SPRING.
To all whom it may concern Be it known that I, BENJAMIN F. Bow- MAN, a citizen of the United States, residing at Berkeley, in the county of Alameda and tate of California, have invented certain new and useful Improvements in Vehicle- Springs, of which the following is a specification.
My invention relates to vehicle springs, and particularly to those of the elliptical type.
The principal object of my invention is to produce such a leaf spring as will be capable of taking a larger seating bolt than possible at present without weakening the spring or impairing its efficiency in any way,
A further object resides in the particular arrangement and combination of parts hereinafter described.
Referring to the accompanying drawing:-Figure 1 is a top plan view of my improved spring. Fig. 2 is a side elevation of the same.
In the drawin the same part is designated by the same reference character in the different views.
Referring more particularly to the drawing, 1 is the axle or bolster of the vehicle which is shown as having an I shaped cross section. My improved leaf spring 2 is secured to the axle 1 by means of a bolt 3 running through the leaves of the spring and also through the axle 1. It will be seen that the spring 2 is composed of a plurality of leaves, one above the other, which are of different lengths, but it should be understood that each of the leaves of the spring is enlarged laterally at its center as indicated at 4 in Fig. 1 but that this enlargement affects the width of the spring only and not the thickness thereof. The objectof the enlargement shown at 4 is to provide such a cross section of metal at this point that the spring shall not be weakened by drilling the Specification of Letters Patent.

Serial No. 756,711.
hole for the bolt 3 therethrough. It will also be observed from Fig. 2 that the axle 1 is enlarged as indicated at l so as to permit the passage of the bolt 3 therethrough without weakening the axle.
On each side of the wide portions 4 the leaves of the spring are held together by U- shaped clamps 5. These clamps prevent any tendency of the leaves to turn.
Having thus described my invention what I claim is i 1. The combination of a support, a spring mounted on top of said support comprising a plurality of superposed leaves, said leaves being enlarged throughout the portion which is above said support and provided with an aperture, a bolt passing through said apertures for fastening said leaves to said sup port, and clamps for binding said leaves together, said clamps being free from the support and arranged one on each side thereof, at the points ofunion between said enlarged portion and the remainder of said leaves.
2. The combination of a support, a spring mounted on top of said support comprising a plurality of superposed leaves, said leaves being enlarged throughout the portion which is above said support, and clamping bands passed around said leaves at the points of union between said enlarged portion and the remainder of the leaves.
3. As an article of manufacture, a spring comprising a plurality of superposed leaves, said leaves having an enlarged perforated central portion, and clamping bands placed around said leaves at the line of union between said enlarged section and the remainder of the leaves.
In testimony whereof I afliX my signature in presence of two witnesses.
BENJAMIN F. BOWMAN.
