SPRING.
Application filed May 23,
To all whom it may concern:
Be it known that I, FRANCIS D. PARKER, a citizen of the United States, residing at Hillsboro, in the county of Vernon and State of Wisconsin, have invented new and useful Improvements in Springs, of which the following is a specification.
This invention relates to a vehicle spring, the general object of the invention being to so construct the spring that friction between the leaves thereof will be eliminated and to equalize the strain on the leaves.
Another object of the invention is to hinge the ends of the leaves together so that the leaves will have free movement.
This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described,
illustrated in the accompanying drawings and specifically pointed out in the appended claim.
In describing my invention in detail, reference will be had to the accompanyingdrawings wherein like characters denote like or corresponding parts throughout the several .views, and in which Figure 1 is a fragmentary view of a vehicle showing my improved spring in use.
Figure 2 is an enlarged side view of the improved spring. 1
Figure 3 is an end view thereof.
Figure f is a section on line 4-4 of Fig-' ure 2.
Figures 5 and 6 are detail views.
As shown in these views the spring is composed of the leaves 1 which are bolted together at their centers by the bolt 2, spacer plates 3 being placed between these 0 springs and the bolt also passes through these plates. hingedly connected together by the shackles 1923. Serial No. 640,988.
4. Each shackle is connected at its top with the upper leaf by means of the clamping plates 5 and 6 which are inclinedly ar- 5 ranged and these plates are bolted together I by the bolts 7 which pass through holes in the projecting ends of the plates. The bottom plate 6 ,is of larger dimensions than the top plate and it is provided with a tubular part 6 for receiving the top bolt of. the shackle. Each end of each leaf is curved downwardly and rolled to provide an eye for receiving the lower bolt of each shackle.
It will thusbe seen that the leaves of the springs are spaced apart and the ends are hingedly connected together by the shackles so that the leaves have free movement which will make then more resilient and this arrangement also eliminates friction produced by one leaf contacting with another. Each leaf does its share of work so that the strain is equalized.
It is thought from the foregoing descrip tion that the advantages and novel features of my invention will be readily apparent.
I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall. 7 within the scope of the appended claim. I
What I claim is A spring of the class described comprising a plurality of leaves connected together at their centers and havin eyes at their ends, a pair of plates clamped to each end of the spring by bolts passing through projectingparts of the plates, one plate of each pair having a tubular part andshackles having their bolts passing through the. eyes and the tubular parts.
In testimony whereof I afliX my signature.
FRANCIS D. PARKER.
