IMPROVEMENT IN WAGON-AXLES.

Specification forming part of Letters Patent N o. 167,843, dated September 21, 1875; application filed July 21, 1875.

To all whom 'it may concern:

Be it known that we, JOSEPH R. LANTZ and THOMAS L. MITCHELL, of Marrowbone, in the county of Moultrie and State of Illinois, have invented a new and valuable Im- I provement in Adjustable Axles; and we do` hereby declare that the following isa full,

clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this speciiication, and to the letters and figures of reference marked thereon.

Figure 1 of the drawing is a representation of a side view of my invention. Fig. 2 is a view showing the under side of the axle and box. Fig. '3 is a detached view of one of the axle-sections. Fig. 4 is an end sectional view, on an enlarged scale, of the box and axle.

This invention relates to extension or adjustable axles for wagons or other vehicles;

and consists in a divided axle of octagonal shape, its sections fitting in a hexagonallyformed sectional box7 by which construction the axle-sections may be locked in place, al"- ter being adjusted to the desired gage of treads, by tightening up of the box upon the axle; also additionally securing it by setscrews upon the ends ofthe axle-sections, workin g in elongated slots formed in the upper section ot' the box, as will be hereinafter more fully set forth.

-In the drawings, A represents the box, of any suitable metal, but preferably of malleable cast-iron, and is formed in two sections, a a', the side pieces Haring outwardly sufciently to correspond when together with the aring sides of the octagonal-shaped axle-sections B. The upper section a of the box A is formed with elongated slots b and shoulders c, against which the heads of suitableset-screws d abut to prevent them from sliding or moving inI box, as vthe box-sections a a are firmly held and clamped around the axle by the clamping-rod e.

To admit a free lateral adjustment of the axle-sections B within the box, theyare formed with elongated slots g, for the passage of the bolts or rods e.

In place of the set-screws d a right-andleft hand screw-rod may be employed, connected to the lower section of the box, and parallel thereto, while the ends of the axlesections are provided with downwardly-projecting plates with screw-threaded openings, into which the right-and-left handed screwrod worksin adjusting the axle-sections within the box.

The construction is very simple, adding no material cost to the manufacture of vehicles, and the operation of adjusting and setting the axle-sections requires but a moments time,

it only being necessary to loosen the screwnuts f sufficiently to relieve the pressure of the sections a a upon the box B, and raise the set-screws d, when the axle-sections may be easily adjusted within the box to the required distance, after which the nuts f are screwed back in place, and the setscrews turned down until their heads are seated against the shoulders c of the elongated slots b. 4

- Having now fully described the construction and operation of my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The octagonal-shaped axle-sections B, in combination with the hexagonal box A, formed in sections a a', and bolt or rod e, for tightening and clamping the sections upon the axle, substantially as specified. l

2. The hexagonalbox A, composed of the sections a a', the latter having slot b and shoulders c, in combination with the Octagonal axle-sections B and set-screw d, substantially as and for the purpose set forth.

In testimony that we claim the above We have hereunto subscribed our names in the presence of two witnesses.
