SPRING CONSTRUCTION.

Specification of Letters Patent.

Patented Feb. 12, 19118.

Application filed April 28, 1917. Serial No. 165,178.

To all whom it may concern:

Be it known that I, JOHN WELsBY GELL- ING, a British, subject, residing at the city of Mexico, Mexico, have invented certain new and useful Improvements in Spring Constructions, of which the following is a specification.

This invention relates to certain new and useful improvements in spring construction.

The primary object of the invention is the provision of a spring adaptable for various uses and arranged whereby a great amount of resiliency is obtained.

A further object is the provision of a spring structure including cooperating leaf and corrugated spring elements.

In the drawings forming a part of this application and in which like designating characters refer to corresponding parts throughout the several views:-

Figure 1 is a longitudinal sectional view of a form of the device formed of a rectangular metallic strip with a thickened central portion.

Fig. 2 is a plan view thereof.

Fig. 3 is a view similar to Fig. 1 with the spring formed of a double tapered metallic strip.

Fig. his a plan view of the same.

Fig. 5 is a view similar to Fig. 1 with the spring formed of a rectangular metallic strip of equal thickness throughout.

Fig. 6 is a plan view thereof.

Fig. 7 is a plan view of a spring formed of a metallic strip having thickened endsand one arcuate side.

Fig. 8 is a longitudinal sectional view I taken upon line VIII--VIII of Fi 7 Fig. 9 is a side view of a dou le leaf spring employing two of the members illustrated in Figs. 5 and 6.

Fig. 10 is a top plan .view thereof.

Fig. 11 is a transverse sectional view taken upon line XI-XLof Fig. 12 of a triple leaf spring.

Fig. 12 is a top plan View of the same.

Fig. 13 is a side view of a double leaf spring employing the members thereof in flat arrangement.

Fi 14 is a sectional view taken XI --XIV of Fig. 13.

The invention broadly consists in the formation of an advantageous spring structure especially serviceable as a vehicle spring upon line formed in slightly different manners, each embodying substantially the same principles, a reslhent metallic strip being arranged in corrugations for accomplishing the desired effect and arranged either vertically, horizontally or at intermediate angles in the formation of the complete device which is formed of one or more alternate or combined flat and corrugated spring members, the latter having lateral, vertical, torsional and reciprocal or longitudinal resiliency and arranged with guide and positioning plates or leaves restricting the movement thereof within the desirable limits.

A resilient metallic strip 10 having parallel edges and tapered in thickness from the central portion 11 to the opposite ends 12 thereof is arranged in waves or corrugations producing the spring formation illustrated in Figs. 1 and 2 of the drawings while a similar strip 13 having opposite convex arcuate sides 14 may be similarly corrugated forming the spring structure illustrated in Figs. 3 and 4.

A metallic strip 15 similar to the strip 10 may be employed having uniform thickness and bent into a plurality of regular loops 16 producing a spring as illustrated in Figs. 5 and 6 While a strip 17 similar thereto but with a single curved or arcuate side 18 may be looped, as illustrated in Figs. 7 and 8 with the largest loop 19 at the center thereof and loops gradually decreasing in length toward the opposite ends 20 of the spring, which ends are preferably thickened for imparting the additional strength in mounting the spring, receiving perforations 21 being arranged through said ends.

A double leaf spring may be formed of two of the spring members 15 forming leaves with the corrugations horizontally and transversely thereof, plates or plain leaf springs 22 being arranged between which the corrugated leaves 15 are positioned and secured in any desired manner, one of the said plates 22 having terminal attaching beads or rolled over ends 23.

In a similar manner three horizontally corrugated spring leaves 24 may be arranged m a spring structure as illustrated in Figs. 11 and 12 of the drawings, preferably having plain leaf springs or separatmg plates 25 therebetween while terminal loops 26 are provided upon the upper leaf 24, the oppobeing preferably convexed and providing a compact structure of great strength possessing eat resihency,

T e different forms of corrugated or shown. in each of Figs. 1 to 8 inclusive may looped leaf springs may also be utilized as illustrated in Figs. 13 and 14 of the drawings and in which a loop arrangement, such for instance, as that illustrated in Fig. 8 is employed with the corrugations vertically positioned as shown at 28, the two corrugated leaves being of different lengths and arranged with positioning leaf springs 29 at each edge thereof while the upper spring 29 is provided with terminal attaching beads 30. t t

.It will be apparent that it is not desired to limit the present invention to any particular form of corrugation, loop, or ad-' vantageous bending of the flexible metallic strips in the formation of the device nor to limit their employment either singly or in plurality, with the loops arranged horizontally or vertically.

' A serviceable spring structure is arranged having great strength and durability as well as possessing great resiliency when subjected to strains both direct as well as torsional,"

such for instance, as those exerted under variable traflic conditions when the invention 'is employed as a vehicle spring.

Obviously, the form of corrugated leaf be used in the construction shown in Figs.'

9 to l linclusive. a

What I claim as new is 1., A spring structure comprising a plural-,

ity of resilient corrugated leaves arranged one above another, vplate leaves interposed between the corrugated leaves, and a plate leaf having means whereby the spring may be attached to a supporting structure.

2A spring structure comprising spaced resilient plate leaves and a plurality of corrugated resilient-leaf springs operatively arranged between said plate leaves, with the corrugations thereof arranged transversely of the said plates.

In testimony whereof I have affixed my signature in presence of two witnesses.
