ANDREW J. SUTHERLAND, OF BATTLE CREEK, MICHIGAN.

RUNNING-GEAR FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 372,391, dated November 1, 1887.

Application filed January 19, 1887. Serial No. 224,775. (No model.)

To all whom it may concern.-

Be it known that 1, ANDRE J. SUTHER- LAND, a citizen of the United States, residing at Battle Creek, county of Calhoun, State of Michigan, have invented a new and useful Vehicle Running-Gear, of which the following is a specification.

This invention has for its object certain improvements in the forward running-gear of a fire-ladder truck, disclosed in a pending application of mine bearing even date herewith, said improvements being designed to be equally applicable to the running-gcars of other vehicles, all substantially as below described and claimed.

In the drawings forming a part of this specification, Figure 1 is a front elevation, with parts in vertical section; Fig. 2, a view looking from a point at the right of Fig. 1,

with parts in vertical section near the kingthe rubber spring ain vertical section, also 5 axle.

showing broken details from Fig. 1 in dotted lines; and Fig. 6 is the same, with details from Fig. 4 in dotted lines.

The several details referred to are indicated by like letters in the figures named, and are more fully described below.

Referring to the lettered parts of the draw ings, O is the forward axle, and B the wheels. The support 0 is secured at each end to the Upon this support the circular rim D, bearing a series of wheels, a, is mounted.

The draw-bars o o are attached to the rim D and the support 0. The tongue y is attached to the forward end of the bars 1; o. The Well-shaped ladder-box A rests on the rollers a a. The truss t is attached at each end to the axle, and the lower end of the kingbolt S passes through the center of the truss t. This truss t is parallel with the axle. A truss, it, may be employed in like relation with the king-bolt transversely beneath the axle C, Fig. 2. One or both of these trusses may be used, as desired. The kingbolt S passes loosely through the support 0, the axle G, the

0 rubber spring 1, and through the truss t or t, or both of the trusses, if both are used. The ladder-box A has a central boss, i, having a hollow socket resting on the upper end of the king-bolt, Figs. 1 and 2.

The king-bolt S has a flange or shoulder, r, resting on the rubber spring 1, said spring resting on the truss. This spring may or may not be employed, and a spiral may be used in lieu thereof. It not employed, the king-bolt would not be cushioned, and the shoulder i" would contact with the truss, said shoulder 1" in the latter-named use, of course, being lower down.

The ladder-box A here shown may serve to illustrate any vehicle-body, so far as its relation to the king-bolt is concerned.

The result attained by the above-described construction is a support of the body by the ends of the axle by means of the king-bolt supporting the body and the truss supporting the king-bolt, thus relieving the axle of all central strain.

It will be observed that the support 0 rests on a shoulder, as, Fig. 5, of the kingbolt S; but this support 0 and the rim D may or may not be employed, but in a heavy laddertruck will be useful when employing the the wellshaped ladder-box.

In Figs. 4 and 6 an ordinary bolster, it, rests on the shoulder :10 of the kingbolt, thus showing another equivalent in the fact that the king-bolt in both cases supports the vehicle body or its bolster, which is the same thing, and the truss supports the king-bolt.

Having thus described my invention, what I claim is 1. The combination of the axle, the truss, a king-bolt passed through the truss and flanged and supported by the truss, and a box or holster provided with a central boss, having a hollow socket resting on the head of the kingbolt, substantially as set forth.

2. The combination of the axle, the truss, the circular rim and its support, a king-bolt supported by the truss, and a box or bolster mounted upon said rim, and having a central socket resting on the head of the kingbolt, substantially as set forth.

In testimony of the foregoing I have hereunto subscribcd my name in presence of two witnesses.

GEORGE W. Mnciinrr, XVILL. It. PnILLIrs.
