WAGON-AXLE.

SPECIFICATION forming part of Letters Patent No. 429,385, dated J' une 3, 1890. Application filed November 25,1889. Serial No. 331,455. (No modelli To @ZZ whom t may concern,.- Y

Be it known that I, HENRY G. MITCHELL, of Racine, in the county of Racine, and in the State of Visconsin, have invented certain new and useful Improvements in Wagon- Axles; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to wagon-axles; and it consists in certain peculiarities of construction, as will be fully set forth hereinafter and subsequently claimed.

In the drawings, Figure l is a side elevation, partly in section, of one end of an axle and its attachments constructed according to one form of my invention. Fig. 2 is an under side view of the'same with the skein removed. Fig. 3 is aperspective view of one form of my axle strengthening bar. Fig. 4 is a plan view of one end of said bar. Figs. 5,'6, and 7 are vertical transverse sections on the lines 5 5, 6 6, and 7 7, respectively,`of Fig. 1. Fig. 8 is a View similar to Fig. 1, but illustrating another form of my present invention. Fig. 9 is an under side plan view of the same with the skein removed; and Figs. 10, 1l, and l2 are vertical transverse sections on the lines 10 10, ll 1l, and 12 l2, respectively, of Fig. 8.

A, Fig. l, represents a wooden axle provided on the under sideV with a 1 -shaped groove or recess B, the horizontal portions of which are merged with the vertical portion at the end, forming an upward-extending recess a, andthis groove B receives a correspending L- shaped metallic strengtheningbar C, whose ends are rounded somewhat on the bottom, as at c2, and then swaged up into the portions b to iit the recesses a, and thence continued out at said elevated plane and formed into screw-bolts c. On the said screw-threaded ends c of the bar C are next placed washers d, which t against the ends of the Wooden axle A, and next them are screwed nuts D. On top of the wooden axle `rest the hounds E, and on them the bolster F, (said hounds and bolsterbeing preferably recessed or shouldered at their meetingpoints, as shown,) and, in the form shown in Fig. l, being secured by clip G, plat-e e, and 5o nutsf H is a skein slipped on each end of the axle, and having a reduced outer end 71with a contracted bore g, of a size just sufficient to receive the screw-threaded end c of the bar C,'the bore of the rest of the skein being of proper size and shape to receive the end of the wooden axle A, and also the washer d and nut D, the said'reduced end h of the skein having a squared inner surface irn- 6o pinging against said nut D,'as shown, and being provided withk exterior screw threads to receive the hub-nut I when the Wheel is in place, while another nut t' is then screwed onto the protruding ends c of the bar C against the outer reduced end h of the skein, thereby tightly clamping all the parts together.

In Figs. S to 12, inclusive, I show a modified construction wherein the bar (marked 7o C) is without any upward central iiange, being'a ilat bar of iron bent up and rounded, as at c2, and then swaged up as before, ,as shown at b, and terminated in screw-bolts o, the attachment of the skein and hub being precisely as already described with the other form of bar. This latter form C of bar may be used with clips, but is especially well adapted for use with bolts G', passing through the wooden axle, hounds, and bolster, and se- 8o cured by nuts, as shown.

My bars C C not only greatly' strengthen the axle, but form an admirable means of securing the axle-skeins and hubs to place.

Having thus described my invention, what I 8 5 claim as new, and desire to secure by Letters Patent, is-r In an improved wagon axle, the combination, with the axlespindle having a longitudinal groove in its under side and an axle- 9o skein surrounding said spindle and having a screw-threaded outer end, of a strengthening-bar embedded in the under side of the spindle and extending outward through the screw-threaded end of the skein, said end of the bar being externally screw threaded, a nut screwed upon the end of the bar and lying Within the outer portion of the skein, a

nut also screwed upon the outer end of the county of Racine and' State of Tisoonsirn in bai' and abutting against the outer end of the presence of two Wltnesses. i

the skein, and a nut screwed upon the outer o f MITCHELL end of the skein, ali substantially as de- HENRX G` 5 scribed. Witnesses:

In testimony that I Claim the foregoing I F. W. AINSWORTH,

have hereunto set my hand, at Racine, in the JOHN FAIRLEY.
