CARRIAGE-SPRING.

SPECIFICATION forming part of Letters Iatent No. 524,929, dated. August 21, 1894. Application filed September 22, 1892. Serial No. 446,577. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES A. BEHLEN, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Carriage Springs, of which the following is a specification.

My invention relates to that class of springs known as end-elliptic.

The object of the invention is to arrange the springs so that they resist the various strains, the springs being placed so that one spring braces the movement of the other, destroys the rolling motion due to end thrusts, and employing three leaves of springs, two of which are placedout of the same horizontal plane, and co-acting so as to cushion against each other, avoiding all liability of jars or jolts, and hence materially lessening the danger of breaking the springs.

The various features of my invention are fully set forth in the description of the accompanying drawings making a part of this specification, in which-- a Figure 1 is a bottom plan view of my improvement attached toa carriage body. Fig. 2 is a rear elevation of the springs. Fig. 3 is an end elevation of Fig. 2. Fig. 4 is a bottom plan view of a. modification of Fig. 1. Fig. 5 is a detail rear elevation of amodifica tion of the spring. attachment. bottom plan view of the same.

1 represents the frame of a carriage.

2 represents the end rails, and 3 cross bars forming the frame.

4 represents axboltster on which the spring A is clamped.

B represents another set of leaves hinged to the axial bolt 00. The said springs A, B, are in parallel vertical planes, so as to pass each other when compressed.

C represents a spring clampedupon the spring B, and hinged to the bracketsD; said brackets are shown in Fig.1 as of T-form, and

connected to the rails 1 and 3. The spring C, preferably, is longer than the spring B, so that when it is depressed it'iwill not strike the joint or eye of the spring B. In the preferred form the clamping bolt on is provided with a sleeve having a collar d in the center. The eye of spring A swiveling on the journal b,

Fig. 6 is a and the eye of spring B swiveling on the jour nal c.

In the modification shown in Fig. 4 the bracket is shown of L-shape and attached to the corners of the carriage body. And in the modification in Figs, 5 and 6, the spring 0 is connected to bracket D by the link 7, one end of which is hinged to the spring C by bolts 8, and the other end to the arm 6 of the bracket D by the center 9 5 this allows the longer spring C to bend with less strain upon the arm D than when connected directly to the same.

It will be observed that when the springs are attached to the bodyas herein shown the spring B passes springA and receives a large portion of the downward motion of the body; and is assisted by the spring C to receive the strains or thrusts of the starting and stopping movement. The spring movement is thoroughly cushioned between these three springs avoiding joltings, which occur when the springs are arranged so as to stop one against the other.

The springs A B while they have a common axis on the bolt (1, each have a separate bearing d, 0, upon the journal sleeve, the eyes of the springs being separated by the collar b or e, and this separation of the springs and the use of the spool or sleeve is an essential requisite to their successful operation, as it avoids shearing or cutting the bolt off caused by the strain of the eyes of the springs in opposite directions across the center portion of the bolt; and by the use of the spool or sleeve journaling on "the bolt thestrains are distributed throughout the entire length of the bolt; the eyes of the springs also abutting against the collars or washers of the head and nut prevents their rocking laterally on the journal in case of wear or lost motion; the latter can be readily taken up by tightening the nuts.

Having described my invention, what I claim is- 1. The combination in a carriage spring, of a bolster, 4 centrally supporting a spring A, a spring B located at one side of the spring on the bolster and connected at its ends therewith, a spring C centrally supported by the spring B and rising and falling with the latter combination with the springs ,A and B 10-;

cated in different vertical planes and having IO their extremities mounted on the said journal.

portions of the sleeves on thepivot bolts, and aspring .O centrally mounted on the spring B and having its ends connected with'the vehicle body, substantially as described.

In testimony whereof I have hereunto set 15 my hand.
