SPRING.

SPECIFICATION forming part of Letters Patent No. 402,888, dated May '7, 1889.

Application filed July 24, 1888. $erial No. 280,859. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE EUGENE BAR- THOLOMEW, of New Haven, in the county of New Haven and State of Connecticut, have invented a new and Improved Vehicle-Spring, of which the following is a full, clear, and exact description.

This invention relates to the mounting of vehicle-bodies, the obj ect of the invention being to dispense with the ordinary forms of platform or elliptic springs, such as those heretofore employed to support the rear end of the body, the invention consisting, essentially, of two pairs of leaf-springs that are cJnnected to the hind axle and to clips that are secured to the under side of the vehiclebody,'the two springs of each pair being held under tension by a central link, whereby the springs are held from rattling, and each pair of springs being connected to a central sp ringbar, as will be hereinafter explained.

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 perspective view of a vehiclebody, represen ting the same as it appears when supported by my improved spring. Fig. 2 is an inverted plan view of the construction illustrated in Fig. 1. Fig. 3 is a detail view of the shackles by which the springs are connected to the vehicle-body. Fig. 4 is a view of a modified form of shackle, and Fig. 5 is a sectional view taken on line 00 5c of Fig. 2.

In constructing such springs as those illustrated in the drawings above referred to I provide leaf springs 10 and 11, as many leaves being employed in each spring as may be necessary to give the desired rigidity. The longest leaves of these springs 10 and 11 are formed with lugs or cars 2, which lugs or ears are apertured to receive bolts 3, the said bolts serving as supports for a link, 12,which is placed as best shown in Fig. 1, and upon the ends of the said longest leaves of the springs I form eyes 4.

In connection with the springs above described I employ a shackle, 13, which is made integral with or rigidly connected to an arm, 14, from which there extends at right angles an arm, 15, the shackle 13 being connected to the vehicle-body by bolts, which are passed through apertures formed in the arms 14 and 15, the arm 14 extending transversely inward from the outer side of the vehicle-body,while the arm 15 runs along parallel with said outer side.

To the rear of the shackles, which I secure to the vehicle-body in about the. position illustrated in Fig. 2, I secure a cross-piece, 17, which extends outward somewhat beyond the sides of the vehicle-body, and to the outwardly-extending ends 18 of the cross-piece 17, I secure the springs 11, the forward ends of said springs and of the springs 10 being connected to the shackles 13 by bolts 5, while the rear ends of the springs 10 and 11 are connected to the hind axle by clips 19, as illustrated.

The cross-piece 17 is made of spring-metal, and is held to the vehicle-body by clips 18, and consequently will give to the extent required to permit the springs 11 to elongate when the vehicle is loaded.

In Fig. 4: I illustrate a shackle having but one downwardly-extending arm, to which the forward ends of the springs 10 and 11 are bolted, and in this view the springs are shown as they appear when their forward ends are brought together in the form of an elliptic spring.

Such a spring as the one above described gives a free easy motion to the vehicle-body, and is perfectly noiseless in its action.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination of two independent springs arranged one above the other and an equalizing-link arranged between and pivoted to the said springs, substantially as described.

2. The combination, with a spring cross-bar adapted for connection with a vehicle-body, of springs 11, connected to said bar, links 12, springs 10, held by said links, shackles to which the forward ends of the springs 10 and 11 are connected, and clips to which the rear ends of the springs are connected, substantially as described.

3. The combination, with springs 1.0 and 11,

of a link, 12, centrally placed between said springs, shackles to which the forward ends of the springs are connected, said shackles being adapted for connection with the vehicle-body, and clips to which the rear ends of the springs are connected, said clips being adapted for connection with the rear axle of the Vehicle, substantially as described.

4. The combination, with a vehicle-body, of shackles 13, connected thereto, sprin eonneeted to said shackles, a cross-piece arranged to the rear of the shackles and to which the springs are connected, links 12, arranged between the springs, and clips 19, to Which the rear ends of the springs are connected, said clips being connected to the hind axle, substantially as described.
