JACOB HOWELL, OF JACKSON, MICHIGAN, ASSIGNOR OF ONE-HALF TO N. B. HALL, OF SAME PLACE.

VEHICLE-AXLE.

SPECIFICATION forming part of Letters Patent No. 242,093, dated May 24, 1881.

Application filed March 26, iasi. (No model.)

To all whom it may concern:

'Be it known that I, JACOB HOWELL, a citizen of the United States, residing at Jackson,

' in the county of Jackson and State of Michigan, have invented certain new and useful Improvements in Vehicle-Axles and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters orfigures of reference marked thereon, which form a part of this specification.

Figure 1 is a longitudinal section of an axle embodying my improvements. Fig.2 is a view of the skein-bolt detached, and Fig. 3 is a perspective of part of one of the axle-pieces.

A represents the upper part of the axle, and B the lower part. These parts are formed of wood of suitable, nature, and each extends in one continuous piece from the outer end of one skein to that of the other. They are tapered at each end at a and b to form the spindles.

Herctofore it has been customary in manufacturing wooden axles to make each of them from one piece. 111 order to attach the reach and houndsto the axle when thus constructed it is necessary to cut mortises, and this necessarily weakens the axles and requires that it should be strengthened by metallic braces and straps.

To avoid the cutting and consequent weakening of the axleIhave devised the form herein shown.

The parts A and B are steamed, so that the wood can be bent without danger to the fiber. After being steamed sufficiently they are then bentinto the shape shown at I in Fig. 1. The part A is of the same length substantially as the part B, and is at the outer ends bent downwardly to conform to the upwardly-bent ends of the part B.

The adjoining faces of the two parts a and b of the spindle are flattened, so that when the parts are secured together a tight joint will be obtained.

C represents a buttin g-rin g which surrounds the spindle and furnishes a bearing for the inner end of the hub to butt against.

' D is the skein, which may be of the ordinary character. It is placed around and holds together the parts a and b of the spindle.

E is a collar. which fits around the outer end of the spindle and serves, together with a nut, F, to lock the skein in place. The nut F engages with the outer end of the skein-bolt G, which is seated in recesses formed in the contiguous faces of the parts a and b. It has ahead, 9, situated transversely to the shank of the bolt, and arranged to bear against the shoulders formed on the inner sides of the wooden parts A and B. This construction and arrangement of the skein-bolt produces a secure fastening. The skein is so arranged that the parts A and B project through it, and the nut F can thus be caused to clamp the collar E, the skein D, and the butting-ring C more firmly than if the screw-thread were carried by one of the parts only, as is the case with some axles as now constructed.

It will be seen that by forming the axle in the manner described I not only avoid the cutting of mortises, but, moreover, produce an arched or truss axle having all the advantages incident to those of that character.

The bolster H, rests upon the central or arched portion of the upper part, A, of the axle. It is held in place by the bolt K, which also pivots the reach, as shown at It.

What I claim is- 1. The vehicle-axle herein described, having the upper part, A, formed of a piece of wood bent downwardly at the outer ends, and the lower part, B, formed of wood bent upwardly at the outer ends, said upper and lower parts, A and B, conforming substantially in shape and construction, whereby they form a double wooden arch, as set forth.

2. In a vehicle-axle, the combination of the lower part extending from end to end of the axle, and the upper part, A, of substantially the same length as the lower part, formed of a piece of wood bent downwardly at the outer ends, and the skein D surrounding said parts the cross-head g, and situated between the sepa- A and B, and situated to have the part A prorable parts A and B of the axle, as set forth. :3 ject through said skein, substantially as set In testimony whereof I am); my signature forth. in presence of two witnesses.

3. In a vehicle-axle, the combination, with JACOB HOWELL.

the upwardly-bent wooden part B and the Witnesses: downwardly-bent wooden part A, separable H. R. HALL, from the part B, of the skein-holt G, having N. O. LOWE.
