SIDE SPRING FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 312,174, dated February 10, 1885.

Application filed October 25, 1884. (No model.) I

To all whom, it may concern:

Be it known that I, JAMES H. SNODGRASS, a citizen of the United States, residing at Miffiinburg, in the county of Union and State of Pennsylvania, have invented a new and useful Improvement in Side Springs, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to side-spring vehicles, and more particularly to an improved coupling orjoint for connecting the ends of the side springs to the front and back springs; and it has for its object to providea device of this character in which the attachment will be strengthened and made superior in every respect, allowing the springs to yield while in use, and work together with readiness and ease, and yet prevent undue strain in any direction.

WVith these ends in view the said invention consists in certain details of construction and combination of parts, as hereinafter set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective View of a portion of the gear of a side-spring vehicle with my improved ooupling-joint for connecting the ends of the side springs to the front and back springs. Fig. 2 is a detached view of a portion of the side and back springs, showing the parts enlarged to bring out the coupling .more clearly. Fig. 3 is asimilar view, showingthe parts separated.

Like letters are used to indicate corresponding parts in the several figures. Referring to the drawings, A B designate the front and back springs, of the usual construction, having their extreme ends provided with upwardly-projecting lugs O G, the front and rear faces of which are curved inward, or cut out at the base, to provide enlarged cylindrical-shaped heads for the lugs, said heads being perforated transversely, as at a.

D D designate the side springs, of the ordinary construction, having their opposite ends passing beneath, around, and overthe front and back springs, substantially in the form of the letter C. .The extreme ends of the side springs are provided on opposite sides with circular disks b b, a portion of the body of the spring being out out between the disks at e to provide room for the lugs O C. These disks 1) have alignedperforations d,to register with the perforations a in the lugs O, to receive a headed bolt, E, to the end of which is fitted a nut, F,which binds against one of the disks and makes the attachment secure in every respect.

The operation of my invention will be readily understood from the foregoing description, taken in connection with the annexed drawings. TheC-shaped ends of the side springs are carried around and over the front and back springs, the extreme ends being coupled together by passing the bolts through the perforations of the disks 1) and the lugs 0. As seen, the disks are arranged on opposite sides of the said lugs O, and held against the same, so that the front and back springs will be permitted to yield downward, but will be braced from lateral motion. In the present manner of coupling the side springs to the front and back springs by the use of shackles or knucklejoints there is too much strain on certain parts. In my construction both the side and end springs mutually support each other and have equal strain placed upon them,while the end springs will be held from moving laterally independent of the side springs. In this manner the action of the springs is made much easier, since they willmove in unison, and thus co-operate to provide a light and efficient spring.- There can be no wrenching or undue strain upon either the end or side springs, while the parts can be detached in a very short time.

My spring is specially adapted for light vehicles-such as are used by physicians and the like-and will provide a light, strong, and simple device, which will prove of great utility for the purposes intended.

Having described my invention, I claim- 1. The combination, with the end springs provided with an upwardly-projecting perforated lug at each end, of the side springs provided with C-extensions at the ends,which pass underneath, around, and over the end springs, the ends of the extensions having perforated disks, and bolts and nuts for coupling the disks to the lugs, as and for the purpose set forth.

2. As an improvement in side springs, the

with upwardl y-proj ectin g lugs at the ends, the

combination, with the end springs provided heads of said lugs being cylindrical in form,of the side springs having their ends passing around and over the end springs, disks on opposite sides of the ends of the side springs, a portion of the latter being cut out between the disks, and a bolt for connecting each pair of disks to the lugs, as and for the purpose set forth.

3. As an improvement in side springs, the combination,with the end springs having perforated lugs at each end, of the side springs arranged below and having their ends passing underneath,aronnd,and over the end springs, and bolts for connecting the ends of the side springs to the lugs, as and for the purpose set forth.
