CHRlS'lOPH HOTZ AND MARTIN CONRAD, CF CHICAGO, ILLINOIS.

WAGON-AXLE.

SPECIFICATION forming part of Letters Patent No. 388,975, dated September 4, 1888.

(No model.)

To all roh/)722. may concern:

Be it known that we, Gnnis'rorn Ho'rz and MARTIN CONRAD, both of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in \Vagon-Axles; and we do hereby declare that the following is a'full, clear, and exact de scription thereof, reference being had to the accompanying drawings, and to the letters of refereneeuiarked tliereon,which form apart of this specification.

This invention relates to devices for more iirinly securi ng skeins upon the arms of wooden wagonaxles; and it has for its object to provide a simple, effective, and conveniently-applied construction for this purpose, and one which also serves asa truss or strengthener for the axle.

rlhe nature of the invention will be understood from the accompanying` drawings and the following description.

In the drawings, Figure l is a side view of the principal part of the front axle of a heavy wagon, having the skeins secured thereon in accordance with our improvement. Fig. 2 is an under side view of the same axle. Fig. 3 is a detached view of the wroughtmetal link which forms part ofthe fastening.

A. represents a wooden wagon-axle; B, one of the two sheet-steel skeins covering the arms of the axle, E', the usual extension of the skein reaching inward over the side and under surfaces ol' the axle, and C a separate collar or harter-band clamped about the skein. To each ofthe extensions B ofthe two opposite skeins is welded or otherwise united a bar, D, usually of thicker material than the sheet ol' which the skein is formed, and extending on the under side of theaxle to within a short distancesay two or three inches, more or less-of the middle of the axle, said barD forming astrong,` continuation of the extension B of the skein. The free end of the bar D is turned outwardly or downwardly from the axle to form a short shallow hook, d, having,` a slight concavity on that' lateral surface thereof which is directed toward the skein to which it is connected. Then the two skeins provided with bars D D are applied to the opposite ends of the axle, the free ends of said bars D Dstand atashort distance apart, (desir-ably from four to six inches.) as shown clearly in both Figs. l and 2 of the drawings. After the skeins provided with these bars have been irinl y forced upon opposite ends of the axle, in the usual way or otherwise, a wrought-iron or forged-steel link, E, Fig. 3, is dropped over the hooksclfl while het, and the sides of the link are then bent inward ordownward, or both, so that the ends of the link will be drawn closely into the slight depressions of the hooks d d. rlhe link is then allowed to cool, and in thc cooling thereof said link by its contraction is made to tightly draw upon the opposite hooks, tending to retain the skeins securely in their place.

The device described may he applied to both front and rear axles, and in the front axle the space within the link between the hooks d d affords room for the protrusion ofthe king-bolt.

The construction described constitutes, as stated, a simple, inexpensive, easily-applied, and extremely secure device for the purpose had in View, and, moreover, serves t-o greatly strengthen the axle by its action as a truss.

NVe claim as ourinvention The combination, with a wagon-axle and opposite skeins, B B, thereon, of the bars D D, connected with the skeins and provided with hooks l (l at their proximate ends, and a shrunk-rnetal link, ll, embracing said hooks, substantially as described.

In testimony that we claim the foregoing as our invention we ai'tix our signatures in prcsence ot' two witnesses.

CHRlSTOPH HOTZ. MARTIN CONRAD.
