HANS SUNDBY, OF STOUGHTON, WISCONSIN.

WAGON-AXLE.

Specification of Letters Patent.

Patented May 27 1913.

Application filed. January 21, 1911. Serial No. 603,855.

To all whom it may concern:

Be it known that I, HANS SUNDBY, a citizen of the United States of America, residing at Stoughton, in the county of Dane and State of Wisconsin, have invented certain new and useful Improvements in Wagon-Axles, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to certain new and useful improvements in wagon axles, and relates more particularly to that type of wagon axle in which thimble skeins are employed, and has for its principal object to provide means for strengthening the axle and skein at the point where the greatest liability for breakage occurs.

The invention has for its further object to provide means for securing the trussbar in such a manner as to better support the axle.

Still further objects are to provide a construction simple and durable in its nature, effective for the purposes for which it is designed, and comparatively inexpensive to manufacture.

The invention consists in the novel construction, combination and arrangement of parts as will be hereinafter specifically described, and then claimed, and in describing the invention in detail, reference will be had to the accompanying drawing forming a part of this specification, wherein like numerals of reference will be employed for indicating like parts throughout the several views of the drawing, in which Figure 1 is a sectional side elevation of a portion of an axle, constructed in accordance with my invention. Fig. 2 is an underneath plan View of the same. Fig. 3 is a cross-sectional view taken on line 3-3 of Fig. 1. Fig. 4: is a similar view taken through the line 4-4 of Fig. 1, and, Fig. 5 is a plan and edge view of the truss-bar partly broken away.

In the drawings, 10 designates the axle, provided at each end (only one end being shown) with the usual tapering spindle portion 11. This spindle portion is provided throughout its length with a central slot 12 which extends some distance into the body of the axle at the inner end of the spindle portion. In this slot is fitted a strengthening-plate 14, completely filling said slot and shaped to conform to the axle and spindleportion of the latter. Said plate is provided on its upper edge with a shoulder 15 and with a notch or seat 16, and on its outer end has a threaded shank 17 to receive a nut 18. On its lower edge, adjacent its inner end, the plate has two spaced lugs or projections 22, the purpose of which will presently appear. On the spindle-portion 11 is fitted the skein 19, provided with sand- collars 20 and 21 respectively. The wheel (not shown) is held on the skein by a nut 23. The upper edge of the plate 14 is flush with the upper face of the axle 10, and the seat 16 in said plate registers with the usual seat made in the axle for the hound 24, on which the bolster 25 rests, the parts being secured by a clip or clevis 26, which spans the bolster, and has its two arms passed through the hound and spanning or straddling the axle, said arms being provided with threaded extremities to receive securing nuts 27 These arms pass through a hound-brace 28, and a cross-bar 29 underlying the said brace and are secured by the aforesaid nuts 27. A truss-bar 30 extends longitudinally of the axle, underneath the same and lies between the brace 28 and bar 29, extending from one skein to the other, the bar 29 being shaped (see Fig. 3) so that the truss-bar may be received between said bar and the houndbrace. The truss-bar 30 is provided with openings 31 to receive the lugs or projections 22 on the lower edge of the strengthening plate 14, said lugs or projections spanning the brace 28 and the bar 29 as shown in Figs. 1 and 2. The said collar 21 is peripherally grooved to receive a clevis 32, the arms of which pass down on opposite sides of the skein and through a cross-bar 33 and also through a hound-brace 34 running from the front hound to the skein 19, the clevis being held by nuts 35 on the threaded ends of the arms. The bar 33 is preferably formed on one end with a hook 36 which receives one end of the stay-chains that connect with the eveners (not shown). The truss-bar has its end held by the bar 33 and hound-brace 34:, the said end being turned downwardly as at 37 to engage one side of said bar 33.

It is a well known fact that axles are subjected to the greatest strain, and most liable to breakage at a point between the sand collar 20 and the end of the major portion or body of the axle. By extending the strengthening plate throughout the length of the spindle-portion of the axle and for some distance into the body of the latter, the axle is efiectually strengthened at its Weakest point. The manner of securing the plate in position by the seating of the hound therein,and the lugs engaging in the trussbar effectually holds same and prevents any independent movement of the plate; the plate is easily applied, necessitating merely the slotting of the axle from the outer end of the spindle-portion inwardly into the axle the desired distance.

\Vhat I claim is:

A device of the class described comprising an axle having a spindle provided With a vertical slot extending centrally the length of the spindle With the slot extending into the body of the axle, a skein mounted upon said spindle, a strengthening plate fitted in and of the same length as said slot, the upper and loWer edges of said plate being flush with the periphery of the spindle and axle for the entire length of the said slotted portion, a shoulder upon the upper edge of the plate against Which the inner end of the skein abuts, means for securing the skein against said shoulder and against the outer end of said plate, said plate notched in its upper edge to form a seat for a hound, lugs carried by the lower edge of the plate adjacent its inner end and depending below the body of the axle, a truss-bar underlying the axle and having openings receiving the lugs of said plate, means for securing the outer end of the truss-bar to the skein securing means whereby the truss-bar also acts to secure the skein on the spindle, a cross-bar extending between the lugs and engaging the trussbar, and means for securing the cross-bar to the axle.

n testimony whereof I aflix my signature in the presence of two Witnesses.

HANS SUN DBY.
