UNITED STATES PATENT OFFICE.

MATTHEW IV." JORY, OF HOBART, INDIANA.

WAGON-AXLE TRUSS.

SPECIFICATION forming part of Letters Patent No. 243,915, dated July 5, 1881.

Application filed April 18, 1881. (Nomodel) To all whom it may concern Be it known that I, M. W. J ORY, of Hobart, county of Lake, and State of Indiana, have invented certain new and useful Improvements in a Wagon-Axle Truss andIdo hereby declare the following to be a full, clear, andexact description thereof, that will enable others to make and use the same, reference being bad to the accompanying drawings, and to letters of reference marked thereon, forming a part of this specification.

The object of this invention is an improvement in wagon-axles, whereby they can be conveniently adjusted to give the required gather and swing to the tapering spindle and impart the required gather to the wheel, the exact construction and arrangement of which will be hereinafter more fully set forth and described in detail.

Figure 1 is an elevation of a wagon axle and bolster embodying my improvement, and Fig. 2 is a detached view of the truss-bar.

Referring to the drawings, A represents the axle; B B, the thimble-skeins; O, the bolster, and D the axle-truss bar. The truss-bar D is attached to the under side of the axle and extends longitudinally therewith, the ends fitting into recesses in the under side of the axle between the same and the inner ends of the skeins B B, as shown in Fig. 1 of the drawings. The ends of the truss-bar are rigidly secured to the axle by means of the bolts a a, which pass through the apertures a a in the trussbar, andare tapped into the axle. The rectangular apertures a a are for the reception of the bolts a a which pass down through the These rectangular slots admit of a lateral movement of the truss-bar as the same is moved nearer to or farther away from the axle by the adj usting-screw F, which passes through the threaded aperture (0 in the longitudinal center of the truss-bar. The point of the adjusting-screw F bears against the metallic plate I), attached to the under side of the axle. By tightening up on the screw F the center of the axle is bowed or forced upward, which has the effect of throwing out the top of the wheel, and when the adjusting-screw is slacked up the opposite effect is produced. The truss-bar also has the effect of greatly strengthening the axle, and confines the weight of the load to the center of the same, thereby allowing a thimble-skein of two and one-half inches in diameter to stand the same strain as a three-inch skein would without thetruss-bar, and giving a longer tenon to the spoke in the same sized hub.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a wagon-axle, the combination, with the truss-bar D, provided with the apertures a a, for the reception of the tap-bolts c a, of the axle A and the thimble-skeins B B, substantially as described.

2. In a wagon-axle, the combination, with the truss-bar D, provided with the rectangular apertures c a and the threaded aperture to, of the adj Listing-screw F, the bearing-plate b, and the axle A, constructed and arranged as herein shown and described.
