VEHICLE-SPRING.

To all whom it may concern:

Be it known that we, KAnL W. HAMMER and CHARLES L. Cnrs'r, citizens of the United States, residing at Dayton, in the county of Mont omery and State of Ohio, have in vent certain new and useful 'Im roveo declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and usethe same, refcrence being had to the accompanying drawning gear of automo iles, and the object of the invention is to provide for the attachment of the assembled leaves of such springs in a manner which will preserve the life of .the spring and will not endanger the breakingof the same. y

In" the present improierinnt s, the leaves of the spring are strengthened at the central point by increasing their width by providing extensions from the opposite edges of the leaves at a central oint, sothat when the leaves are assemble one on top of the other, there are a series of lugs centrally disposed on opposite sides of the sprin s as a whole. These lugs add 'to the strengili of the spring at such point and coiiperate with other means in the form of a band which encircles the central point of the assembled leaves, in preventin the individual leaves from having any in ependent lateral or longitudinal movement, all as will hereinafter more fully appear from, the specification and the accompanying drawings forming a part thereof.

- In the accompanyingdrawings, Figure 1, is a yiew of the s ring s pwin one form of clam band or uniting t e individual spring eaves. Fig. 2, is a view of one of the leaves removed from the assembled leaves in Fig. 1. Fig. 3, is a view of the inclosing band or clamp removedfrom Fig. 1. .Fig. 4, is a lan view of the band or clamp shown in igs. l and 3, before the Specification of Letters Patent. Patented July 26, 1910.

Application filed May 3, 1909. Serial No. 493,553.

same is united to the assemblage of leaves. Fig. 5, is a plan view of the band or clamp shown in Fig. 6. Fig. 6, is a view similar to Fig. 1 showing a modification in the useof the band or clamp in uniting the individual leaves to form the spring. Fig. 7, is a cross sectional view of Fig. 6'-0n one side of the surrounding band or clamp. Fig. 8, is a side view of a semi-elliptic or lower half of an elliptic spring, the leaves of which are united by the method or means shown in Figs. 6 and 7.

I In the detailed description of the invention, similar reference characters indicate corresponding parts. I

The individual leaves l which when assembled, constitute a semi-elliptic spring, are rovided as shown in Figs. 1 and 2 of the rawings, with lateral extensions or lugs 5 centrally disposed on the opposite edges thereof, which when the leaves are assembled, are in alinement with each other and thus provide a series of lugs extendin throu hout the depth of the s rin on eac 1 side ,t ereof and at the contra point of the assembla e. At the points, where these In S extend, the leaves are strengthened by ma ing them wider at such points. The vertical shoulders thus formed atthe ends of the extensions or lugs? are en aged by the inclosing band or clamp 3 w iich is provided with two openings 6 which receive the extensions or In s 5 w on the band or clamp is made to inc ose the assembled leaves as in Fig. l. The clamp 3 is extended around the assembled leaves and is overlapped at its Y ends and united by arivet as at 4. There is thus formed between the vertical sides of the clamp and the lugs 5 on each side of the spring, connection which 'revents any independent lon itudinal or ateral movement of the in ividual leaves constituting the spring as a whole, and said spring is secu'rel held. A different connection may be ma e between the shoulders formed by the lugs 5 and the clamp, for example, in Fig. 5, the clamp is shown to have two lateral extensions 6' rojecting from the op osite edges thereog: which, when the clamp lIiClOSCS the assembled spring, are bent aroundthe shoulders formed by the extensions or lugs 5. This idea of means is more clearly shown in Figs. 6 and 7, where it will be seen the lips or extensions 6' reach around the shoulders of the lugs 5 and thus lock the WVe claim:

same manner as hereinbefore described.

A semi-elli tical spring, eomprising an as semblage of e of which 1s p sion on opposite edges of the central portion thereof, which increase the width of the spring at its center and thereby strengthen the same, and provide two vertical shoulders on each side of the springi and a clamping band surrounding the $511 aves of varying lengths, each rovided with a single extenspring and interlocking with said shoulders to rigidly bind the leaves together and lateral or Ion itudinal moveme dividual mem ers of the sprin prevent any nt of the in- 15 In testimony whereof we afi x our signatures, in pr'esenceof two witnesses.
