SPRING-SUPPORT FOR BODY-LOOPS.

SPECIFICATION forming part of Letters Patent No. 554,107, dated February 4, 1896.

Application filed May 27, 1895. Serial No. 550,849. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES A. BEHLEN, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Body-Loop Spring-Supports, of whichthe following is a specification.

The object of my invention is to provide a shackle-support for an end elliptic spring of a carriage, so that the spring is suspended by outwardly-pendent shackles, whereby the spring is allowed free movement without requiring stops, avoiding the contact of the springs with the supporting parts and the use of shackle-joints, thereby obtaining a strong durable support and a perfectly free and untrammeled action of the spring.

The features of my invention will be more fully set forth in the description of the accompanying drawings, making a part of this specification, in which- Figure 1 represents an end elevation of my improvement in position for use. Fig. 2 is a side elevation showing the spring-supports in section. Fig. 3 is asimilar view of the springsupports, showing a modified form of con structing the same. Fig. 4 is another modification of the support shown in Fig. 21 Fig. 5 is still another modification. Fig. 6 is a front elevation of the parts shown in Fig. 5. Fig. 7 is another modification of the spring-support.

A represents the carriage-body; B B, ordinary elliptic springs, the lower limb, B, supported upon a head-block or an axle in the usual manner.

0 represents the suspending cushioningspring. It is rigidly connected to the limb B by clips or bolts 0.

It has been difficult to suspend an end elliptic spring by means of a supplemental hung spring superimposed upon a common elliptic spring because of the wear and rattle of the joints and the lack of a rigid support for the suspending spring. I overcome these difliculties by providing rigid connection of the supports for the spring 0 to the body-loops D D, which are shown as connected to the under side of the carriage-body, each having an outward-turned arm and an overhanging head E, to which heads the supports of the spring 0 are rigidly attached and suspended from the under side.

In practice I prefer to have the spring 0 slightly curved and hinged to a shackle-bolt rigidly connected to the body-loops, which by reason of their construction have sufficient elasticity to yield outwardly and inwardly to take up the lengthening and shortening of the spring as it raises and lowers under the vibrations of the body.

By curving the spring slightly, as shown, about one half of the flexibility of the body loop arms is in an inward direction and the other half of the yielding motion is outward from the normal vertical position of the arms of the body-loops. Thus the body-loops themselves take up the lengthening and shortening spring movements, and this allows the springs to be firmlysupported by unyielding shackles rigidly connected to the body-loops.

I have shown four forms of pivotal shacklesupports for the springs connected to the body-loops, all of them being of the shackle or stirrup form.

G represents shackles which are rigidly secured to the overhangingheads E of the bodyloops D D, preferably by employing a bolt passing through these parts.

In Fig. 3 I have shown a shackle provided with a boss d seated in a correspondinglyformed recess in the overhanging head E. This secures a more rigid attachment of the shackles to the heads.

In Fig. 4 the bolt is shown as made separate from the shackle instead of being formed integral therewith, as shown in Fig. 2.

In Figs. 5 and 6 I have shown the shackle modified so as to support the spring O when it is provided with ears 6; but this is one of the usual forms of journaling the spring upon its pivotal bolts.

In Fig. 7 I have shown the limbs of the shackle made integral with the head E of the body-loop D.

By this construction the side movement of the carriage-body due to the use of shacklelinks for the springcouplings is avoided.

This form of construction also accomplishes another very important resultthe lon gitudinal movement of the body which takes place when links or hinged couplings are employed is almost Wholly overcome.

It has been proposed to support elliptic springs by a spring connection with the bodyloop, but in such cases a swinging shackle with a stop device has been employed, an instance of which is shown in Letters Patent No. 533,429, granted me February5, 1895; but by making the spring but slightly curved, which supports the elliptic spring, and hinging it to a rigid shackle it Will serve as a cushion spring-support having but very little vertical movement, yet sufficient to overcome the jars occasioned by the sudden compression of the elliptic spring, and avoiding the
