EDWARD HUTOI-IINSON, OF NEW YORK, N. Y.

VEHICLE-SPRING.

SPECIFICATION forming part of Letters Patent No. 402,833, dated May '7, 1889.

Application filed September 25, 1888. Serial No. 286,306- (No model.)

To all whom it may concern.-

Be it known that I, EDWARD HUToHINsoN, of the city, county, and State of New York, have invented a new and Improved Vehicle- Spring, of which the following is a full, clear, and exact description.

My invention relates to an improvement in 'ehicle-springs, especially to that class of springs adapted for attachment to a headblock and the support of side bars; and the object of the invention is to provide a spring of simple and durable construction and of light weight and great strength.

The further object of the invention is to provide a spring which will not strike the head-block orbe compressed to a disagreeable extent when the Weight of a person mounting is brought to bear upon one side.

The invention consists in the construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a front elevation of the spring,-

illustrating the same as attached to a headblock. Fig. 2 is a bottom plan view of the upper leaf, and Fig. 3 is a plan view of the lower leaf.

In the drawings the spring is illustrated as attached to a head-block of peculiar construction, for which I have filed an application for Letters Patent of even date herewith; but I desire it understood that the spring may be employed in connection with head-blocks of any approved description.

In carrying out the invention the spring consists of two leaves, 10 and 11, of unequal length, adapted to operate in unison.

The lower leaf is the shorter, and is provided with upwardly and inwardly curved approaching extremities 12, having produced therein an essentially U-shaped recess, 13, as best shown in Fig. 3. The upper leaf, 11, is

held in contact at the center with the equivalent surface of the lower leaf and curved from said central portion upward and outward, as illustrated at 14 in Fig. 1, to a bearing upon the extremities of the lower leaf. From this latter point of contact the upper leaf is carried horizontally outward beyond of a width essentially equal to the width of the recesses 13. The plates 16 are purposed to act as tongues or guides, and are attached at the outer end only, the inner end, which is free and made to follow the contour of the upper leaf, being engaged at the side edges by the side walls of said recesses 13.

The guide plates or tongues maybe secured to the upper spring-leaf by a rivet or equivalent retaining device; but the preferred mode of attachment is through the medium of clips 17, utilized to secure the side bars in contact with the spring. A

It will be observed that, owing to the peculiar shape of the spring, when the latter is mounted upon the head-block 18 and the body of the vehicle placed in position, if the vehicle is mounted and the weight of the party is brought to bear upon one side of the spring, the upper leaf is stiffened by the lower leaf, and the spring thereby prevented from flexing to a disagreeable extent.

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

1. A spring consisting of two leaves, the lower leaf shorter than the upper leaf, the lower leaf provided with upwardly and iiiwardly curved recessed ends, and the upper leaf provided with a con caved central portion and horizontal ends, and a guide secured at one end beneath the extremities of the upper leaf, the free end of the guide-plates sliding in the recess of the lower leaf, substantially as shown and described.

2. In a vehicle-spring, the combination, with the lower leaf having upwardly and inwardly curved approaching recessed ends, of an upper leaf of greater length provided with a central concaved portion and horizontal end portions, and a guide-plate secu red at one end to the under face of the upper leaf at the extremities, the free end of said guide-plates sliding in the recesses of the lower leaf, substantially as shown and described.
