" AXLE-'SKEIN.

SPECIFICATION forming part of Letters Patent No. 400,685, dated, April 2, 1889. Application filed June 30, 1888. Serial No. 278,627. (No model.)

To all whom it may concern.-

Be it known that 1, JOHN A. JOHNSON, a citizen of the United States, and a resident of Madison, in the county of Dane and State of Wisconsin, have invented certain new and useful Improvements in Wagon-Axle Skeins; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure 1 is a longitudinal sectional view of my improved axle and axle-skein; and Fig. 2 is an end view of the same, looking in the direction denoted by the arrow in Fig. 1.

Like letters of reference denote corresponding parts in both the figures.

My invention has relation to metallic wagon-axles of that class which are provided with a cast-iron thimble-skein; and it consists in the improved construction of the skein, as will be hereinafter more fully described and claimed.

In the accompanying drawings, the letter A denotes the arm of a metallic wagon-axle, and B thecast-ironthimble-skein. The latter is provided with the usual hub-flange, O, and has a rearwardly-projecting bolster, D, overlapping and protecting the axle A on its under side. This skein is preferably made of cast-iron, and after casting it ,it is bored out to fit the axle, the centralpart of the bore being enlarged, as shown at E. This enlargement may beformed either during the process of casting the skein, or it maybe formed with the axle.

during the process of boring the same. After the skein has been bored to the proper size to fit the axle it is seated and shrunk upon the same, so as to become firmly united thereto without the use of screws, bolts, welding, or other means of fastening. The object of constructing the skein with the central enlargement, E, is that by this construction the opposite ends of the skein will hug and clamp the axle firmer than if the skein had an in side bearing upon the axle along its entire length. As the metal cools it will shrink onto the axle at opposite ends of the enlargement E, thereby making a very tight and solid fit, so that it is practically as solid and substantial as if the skein had been cast in one piece In this manner I can use an ordinary round rolled axle without flattening its ends, and yet provide it with a skein which shall be absolutely safe.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States The combination, with the cylindrical j ournal of the metallic axle A, of the skein B, shrunk upon said journal, having the annular chamber E, and provided with the collar O and the inwardly-projecting bolster D, which collar and bolster are integral with the skein, substantially as specified.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.
