SPRING FOR VEHlCLES.
APPLICATION FILED 05c. 15. 1919.

I a (fit/teases [nae/21 01 W o't ww John jvj furphg WWW W 06 fiat-leery -ETE Y SA srnnve FOR VEHICLES.
T0 (ZZZ whom it mag concern: r I
Be it known that 1, JOHN N. lvglunriix, a citizen of the United States, residing at 20 Chapel street, Saylesville, in the county of Providence and State of Rhode Island, have invented certainnew and useful Improvements in Springs for Vehicles, of which the following is a specification.
My invention relates to springs for vehicles and the purpose of my invention is to provide a laminated spring which will not require to be perforated for belts in order to retain the leaves in position, but
which will have an enveloping clasp adapted to inclose the spring at or about it middle portion, which clasp is united to the spring leaves by welding in the manner hereinafter described.
My device is explained in the drawings accompanying this petition, in which Figure 1 represents the blank for the enveloping clasp before its application to the spring.
Fig. 2, a sectional view of the clasp in place upon the spring through the line yy of Fig. 4:.
F i 3, a cross-section through the line X- of Fig. 2.
Fig. 4:, a perspective of a portion of the spring with the clasp in place.
The same letters refer to the same parts throughout the various drawings.
In Fig. 1 A is the blank, forming the clasp before being applied to the springand consists of a suitably sized and shaped strip of bar metal of a thickness in proportion to the strength of the sprin to which it is to be applied. This blank 3 is perforated as shown at c--c with one or more rectangular openings beveled as shown at b-b', the length of the rectangular openings c-0 be-' ing the same as the combined thickness of the various leaves of the spring to which it is to be applied. I
S represents the leaves of the spring throughout.
While I have shown two openings cc in the drawing, I may use in some springs only one such opening, or I may use more than two, the number depending on the character of the spring.
The clasp A is applied to the spring as shown in Figs. 2 and 4: by first bending the same over a suitable form and then sliding it over the end of the spring. When first applied to the spring, the extremities of the Specification of Letters Patent. v Patented Mar. 1 1921'. r Application filed December 15, 1919. Serial No. 344,501., v
clasp A will leave a space adjacent to their llneof union, as shown at a, Fig. 4. The" rectangular openings 0-0 are so beveled as to have their Widest portion of the open-v ing outward and narrowing inward as shown at Z) in Fig.3. V
When the clasp 'A has been placed upon its spr1ng,-it .is' clamped temporarily and the space at a, Fig. 4,. and those formedfby, the rectangular openingc-0 shown in the same figure arethen filled in by the electric or other suitable welding process, the beveling of the openings 0c" aiding in the application of the heat.
By the welding process the clasp'A and the several leaves of the spring are firmly united so as to form practically a single .body, the welded portion a giving additional strength.
By the use of the rectangular openings 0-0 the Welding process is greatly facilitated and the union of the clasp with the spring leaves made much stronger.
In Figs. 2, 3 and 4 the clasp is shown after the welding hastaken place at one'of the rectangular openings, the welding substance being represented by 0 and the welding material at the ends of the clasp being shown in Figs. 2 and'i'by a.
By my process, the spring is strengthened at the middle portion, whereas by the use of bolts or other perforations it is actually weakened. The clasp is cheap and readily constructed, the blanks A being readily struck out of suitable bar metal and the application to the spring is quickly, easily,
- and inexpensively made.
The welding process expands the clasp slightly and as its union with the spring is formed while the parts are hot, the subsequent cooling contracts the clasp and makes its grip on the leaves more secure.
I am aware that prior to my invention the welding process has been used for the I claim and desire to secure by Letters Patent is p 1. In a vehicle leaf spring, a plurality of leaves, a clasp inclosing the leaves, said clasp being formed of a strip having spaced slots therein extending longitudinally of the T 1 OFFICE.
purpose of uniting spring leaves together,
strip, the ends of the clasp being spaced from each other and a welding material in one of said slots and between the ends of the clasp for uniting the clasp to the spring leaves. 1
2. In a vehicle leaf spring, a plurality of leaves, a clasp inclosing the leaves, said clasp being formed of a strip having spaced slots therein extending longitudinally of the strip with one slot opening at one end of the strip, the ends of the clasp being spaced from each other, and a welding material in the end slot and extending between the ends of the clasp for uniting the clasp to the spring leaves. 7
3. In a vehicle leaf spring, a plurality of leaves, a clasp inclosing the leaves, said clasp being formed of a strip having spaced slots therein with the side walls thereof outwardly beveled and extending longitudinally of the strip with one slot opening at one end of the strip, the ends of the clasp being spaced from each other, and a welding material in the end slot and extending between-the ends of the clasp for uniting the clasp to the spring leaves.
4. In a vehicle leaf spring, a plurality of leaves, and a clasp inclosing the leaves, and having portions thereof welded to the leaves.
5. In a vehicle leaf spring, a plurality ofleaves, a clasp inclosingthe leaves, and having portions thereof cutaway, and welding material sealing the clasp to the leaves at the cutaway portions.
In testimony whereof I aflix my signatiue in presence of two witnesses.
