VEHICLE-SPRING.

SPECIFICATION forming part of Letters Patent No. 280,613, dated July 3, 1883.

Application filed April 13, 1883. (No model.)

To all whom it may concern:

Be it known that r, JACOB HANSER, of 0X ford, in the county of Butler and State of Ohio, have invented a new and Improved Spring for Side-Bar Wagons and Buggies, of which the following is a full, clear, and exact description.

My improved spring consists of two or more flat leaf-springs connected to spring-bars, and also to levers pivoted to said bars, which levers connect with the side bars, respectively, the levers being pivoted to shackles that have play along the spring-bars to compensate for the lengthening and shortening of the springs, making a simple, strong, and compact arrangement for side-bar wagons, as hereinafter fully described.

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

Figure 1 is a transverse section through the side bars, showing the springs and levers in side elevation, and the spring-bar partly in side elevation and partly in longitudinal section. Fig. 2 is a plan of the spring device inverted. Fig. 3 is a section of Figs. 1 and 2 on line a a2, and Fig. 4 is a perspective view of the shackle used in connecting the levers to the spring-bar.

I take afiat-bottomed bar, a, of wood, shorter than the distance between the side bars, b, and wide enough for applying the flat springs 11 to the margins of the under side, also the levers 6 between said springs, and secure said springs to the opposite margins of the opposite ends, as shown in Fig. 2, by bolting them at g, and connecting the levers by means of clips h, to which they are pivoted, and which are dove; tailed in the attaching-plates i, so that they may shift forward and backward a little to compensate for the lengthening and shortening of theisprings, and also of the lines between centers as the body rises and falls. The free ends of the springs (Z are pivoted to the inner ends of the levers e at j, and the outer ends of 5 the levers are pivoted at 7a to shackles l of the side bars, I).

- In order that the levers e may be in line with each other, and at the same time to enable the springs (Z to have greater length than the distance between the fulcrum-shackles h would allow, the said springs are placed as far apart on the bar a transversely as the space required for the fulcrum-shackles, and the levers are bent at m to the right and left hand to coincide with the springs, respectively. I use springs of two or more leaves, according to the power required, making the upper leaves or plates the long ones and connecting the le vers to them because the thrust of the weight is downward on them. The plates 73, in which the lever-shackles h arefitted, are bolted to the spring-bar by bolts 01.

It will be seen that by the adjustable contrivance of the lever-fulerums the side bars are relieved of lateral thrusts, to which they would otherwise be subject, and by the substantial backing the bar a affords to the springs they will be much less liable to break by the rebound of the body, which is often the most destructive to the springs.

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

1 The levers e, in combination with side bars, b, springs d, and spring-bar a, said levers being connected to the spring-bar by adjustable fulcrums h, substantially as described.

2. The springs d, arranged on the opposite ends of the spring-bar,,with spaces between them for the lever-fulcrums, and the levers arranged in line with each other, and bent at on to connect with said springs, substantially as described.

JACOB HANSER.
