VEHICLE-SPRING.

Specification of Letters Patent.

Patented Sept. so, rare.

Application filed July 28, 1913. Serial No. 781,582.

My invention relates to springs for ve-. hicles, and has for its object to provide certain improvements in the construction of the same as will be hereinafter more particularly described and claimed, reference being had to the accompanying drawing, in which the figure is a view partly inside elevation. and partly in section of my improved device.

In the said drawing the reference numeral 1 denotes the central one of a series of three spring leaves, the outer and. inner ones of which are indicated respectively at Q and 3. Said leaves are brought together at their upper ends, where they are clipped at 4 to the vehicle body, and being curved on the arcs of circles, are gradually separated as they leave said vehicle body to a point sub stantially midway of their curvature, where they are most widely separated, and are then gradually brought into contact again near their lower ends, as shown. At their extreme lower ends the central leaf 1 is curved around a small bushing 5,.the end of outer leaf 2 being curved around the curved end of leaf 1, while theend of inner leaf 3 is similarly curved around the curved endof leaf 2, but in the opposite direction, the whole forming what may be termed an in terlocking eye connection with said'bushing. Said leaf 3 is extended at its end into a tongue 6, for a purpose hereinafter to be described. Passing through said bushing 5 is a bolt 7 which connects said bushing Wltll the free ends of the parallel arms ofa bracket link 8, which is at its upper end pivoted at 9 to the outer end ofthe leaf spring 10 commonly used in automobiles. Said link 8 extends beyond the point of'connection therewith of the bolt 7 and carries a transversely disposed anti-friction roller 11 mounted on a rod 12, against which the upper face of tongue 6 will contact. In order to provide means for preventing lat eral displacement of the ends of the spring leaves with respect to the bushing 5, I pref erably widen the parallel arms of bracket link 8 at 13 to inclose said interlocking eye, said widened portions also acting as dust guards.

In operation upon a relative movement of the parts toward each other there will be a slight movement of the ends of leaves 2 and 3 sliding oppositely around the end of the leaf 1, said leaves at the same time at their two points .of separation increasing their surface of contact under the compression, thus stiffening the resistance offered in proportion to the load imposed.

An important feature of my invention is found in the tongue 6, which by its engagement beneath anti-friction roller 11 acts as a support for the lower end of bracket link 8 whenthe latter is disposed to any extent out of a vertical line, as is the case with the construction shown in the drawing, where the spring 10 is of considerable length. This feature adapts my device to be applied to automobiles previously equipped with other forms of springs, and enables the leaf springs 10 of said prior equipment to be utilized, no matter how long said springs 10 may be. A further and important function of said tongue 6 is to act as a cushion to neutralize small vibrations.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. A scroll spring for vehicles, embodying nested spring leaves gradually separating towardtheir centers, and formed at their outer ends with eyes that interlock to connect said ends with each other.

, 2. A scroll spring for vehicles, embodying nested spring leaves gradually -separating toward their centers and formed at their outer ends into eyes that interlock to connect said ends to each other, and a leaf spring resiliently supporting said spring leaves from said interlocking eyes.

8. A scroll spring for vehicles, embodying nested spring leaves brought together at their ends and gradually separating toward their centers and formed at their outer ends into eyes that interlock to connect said ends outer ends into eyes that interlock to connect said ends to each other, a bracket link pivoted to said interlocking eyes, and a leaf spring resiliently supporting said bracket link. 7 r

5. A scroll spring for vehicles, embodying nested spring leaves gradually separating toward their centers, and formed at their outer ends With eyes that interlock to connect said ends with each other, a bracket link pivoted to said interlocking eyes intermediate its length, a tongue forming a con tinuation of one of said spring leaves and frictionally engaging the outer end of said bracket link to support and cushion the same, and a leaf spring resiliently supporting said bracket link.

6. A scroll spring for vehicles, embodying pivoted to said interlocking eyes intermedi ate its length, a tongue forming a continuation of one of said spring leaves and frictionally engaging the outer end of said bracket link to support and cushion the same, and a leaf spring'resiliently supporting said bracket link. 7 i

In testimony whereof I affix my signature, in the presence of two subscribing Witnesses.
