AxLE-SKEIN.

SPEC'IFIMCATION forming part of Letters Patent No. 277,624, dated May 15, 18183.

` Application filed March 21, 1883. (No model.)

To all whom it may concern Be it known that I, ALBERT H. SOUTH- WORTH, a citizen of the United States, residingat Lockport, in the county oi'Niagara, in the 5 State of New York, have invented a certain new and useful Improvement in Axle-Skeins, which is fully set forth in the following specification, reference being had tothe accompanying drawings, in which- Figure l is aplan view ot an axle skein hav- 'ing my improvement. Fig. 2 is a section on the line v w in Fig. l. Fig. 3 is a section on the line y y in Fig. 2.

The same letters denote the same parts in i5 all the h'gures. p

My invention relates to metallic skeins for axles; and the object ol' it is to combine Athe advantages of a wrought-skein ith thoseof a cast skein:

To this end it consistsin askein of wrought metal, having a sleeve, collar, or yoke cast thereon.

In the drawings, A denotes a skein, formed ot' steel or other wrought metal, consisting of z5 the spindle a, inclosing the end of the axletree, and the extension a', supporting the thicker part ofthe axle-tree, but eut away atthe top. The superior lightness and strength of such a skein, when formed of sheet-steel, 3o make the employment of th-at material very desirable but it is also very desirable that the skein should have an enlargement toward the inner end of the spindle, so as to takein more wood, and thereby give greater strength to the 35 axle-tree, and it is very difficultto form such an enlargement in a wrought skein. Itis also extremely difticult and expensive to form lugs or an oiling-cup with its connected grooves and tubes on a wrought skein. For these 4o reasons wrought skeins have not come into general use.

In order to combine all the advantages which I have enumerated, I cast upon the wrought skein, around the larger end of the spindle and 4 5 theadjoining part ofthe extension a, a sleeve,

B, of suitable shape to inclose the spindle and the adjoining part of the extension,and having which to turn the axle-tree.

on its outer end a circular collar, B. On the upper side, however, beyond the collar, the outline of the sleeve rises above the line of a 5o circular arc, its inner surface being circular Where it adjoins the spindle, but its outer sur- .face being nearly straight-sided for a short distance above the horizontal diameter, thereby making the upper part ot' the sleeve thicker 55 there thairthe lower part. Just beyond the spindle, however, this thickness diminishes from within, so that au enlargement, b, is formed capable ot` containinga corresponding enlargement ofthe axletree.

To etl'ect the union ol" the sleeve which I have described with a wrought-skein, l first forni the'latter complete in the usual way, then insert it in a mold ol' suitable form, and pour in the molten metal furthe sleeve. I 65 iind by experiment that the sleeve is thus joined to the skein with a firmness practically equal io that produced by welding. `Obviously, by giving the requisite shape to the mold, lugs maybe formed ou the collar or 7o` sleeve, and depressions may be sunk in it, so as to form an oil -cup with its connected grooves. In addition to these advantages oi' a cast skein, the sleeve affords a guide by The want ot' suoli 75 a guide is a serious objection to the use ot' wrought skeins, since they generally have an open top at the larger end.

By shaping the mold accordingly the lower part ot' the sleeve might be dispensed with Se and a mere yoke cast on the skein in which to A forni the enlargement b,- bnt it is obviously preferable to have the sleeve embrace the skein.

Vhat I claim as new, and by Letters Patent, is

An axle-skein of wrought metal, in combination with a sleeve, collar, or yoke cast thereon, substantially as and for the purpose described.
