Letters Patent No. 89,602, dated May 4, 1869.

nuPRovnD AxLzi-SKEIN.

The Schedule-referred to in these Letters Patent and making part of the same.

To all whom it mag/concern:

Be it known that I, GorTLInB SCHREYER, of Go- I lumbus, inthe county of Franklin, and State of Ohio,

have invented a new and useful Improvement on Axle- Sk'eins; and I do hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings, making apart of this speeicatiomin which- Figure 1 is a top view of the improved axle-skein complete.

Figure 2 is a section through an axle, having the improved skein applied to it.

Figure 3 is a perspective view of the blank or plate from which the improved skein is made.

Figure 4 shows the plate or blank after it has been shaped, ready for bending and welding, to form the skein.

Figure 5 is alongitudinal edge view of fig. 4.

Figure' is a cross-section through Iig. 4, taken at the point indicated by line z z.

Figure 7 is a cross-section through iig. 2, taken at the point x zt.

Figure 8 is a cross-section through iig. 2, taken at the point y y.

. Similar letters of reference indicate parts in the several figures.

This invention relates to a new and useful improvement which I have made on the axle-skein described in the schedule annexed to my Letters Patent of the United States, granted onthe 7th day of May, 1861. The axle-skein therein described was made by iirst thinning the edges of a plate of metalof proper shape, and then bending this plate about a core, and welding its thinned edges together along the top of the skein, thereby having the metal thickest at the smallest end and also along the bottom of the skein, whereit was subject to the greatest wear.

A- plug, upon which a screw-thread was out, was welded into the smallest end of the skein, and a collar upon it at the proper point, to receive the inner end ofthe nave of a wheel.

The nature of my invention and improvement consists in so shaping vthe blank, plate, or piece of metal of which the skein is produced by operations of bending and welding, that I am enabled to form, during said operations, a cylindrical open portion upon the smallestend of the skein, of uniform thickness of metal, upon which cylindrical portion the screw-thread is out to `receive lthe nut that keeps the wheel in place on the skein, thereby obviatingmnch of the labor, expense, and loss of time required to insert the screw-plug, as described in my Letters Patent above referred to, and also preventing dry-rot from occurring in the wooden axle which receives the skein, as will be hereinafter explained.4

'.lo enable others skilled in the art to understand my invention, I will describe its construction and operation.

p I take an oblong rectangular plate, A, iig. 3, of proper length, width, and of a uniform thickness, and

corresponding by a` process of forging or rolling, I reduce its longtudinal edges from f to g, as indicated in figs. 5, 6, and 8, so as to leave ,its central portion at a c the thickest part. This plate thus bevelled is cut, so as to present about the shape shown in tig. 4, one portion of which is to form an open sheath, another portion the tapering body or barrel, and the other portion the cylindrical terminal end of the skein. Or, if desirable, the plate or blank may be out from a sheet of steel, of the form shown in iig. 4, and its surfaces afterward bevelled or tapered.

By reference to figs. 5 and 6, and 7 and 8, the shape of the blank in cross-section will be clearly understood.

My object is to have the thickest parts of the metal forming the skein at the points where the skein is subject to most wear, also to have the edges ff the thinnest where they are broughttogether on top of the skein, and finally to have that part of the blank which forms the cylindrical end g, equal in thickness to the thickest part a of the skein. rIhese resnltsI obtain by bevelling or reducing the plate from its centre to its edges for a greater portion of its length.

'lhe blank, represented by iig. 4, is applied upon a suitable form, corresponding in shape and size to the shape and size of the axle upon which the iinished skein is to be applied, and by processes of bending and welding the edges ofthe blau-k are brought together, lapped, and welded, so as to present the appearance shown in iig. l.

The skein is then finished, ready for application to its axle by cutting a screw-thread upon its cylindrical open end g, which thread is designed to receive a nut, N, required at this point to keep the wheel upon its axle-arm.

The skein is now driven tightly on the axle-arm G,

and a collar, F, and shoulder-band, E, driven on this.

arm, and shrunk tightly in their places, which, with a bolt, a', securely conline the skein upon the a'Xle-arm, and also atford an abutment for the inner end of the hub ofthe wheel when upon this skein.

It will be seen from the above description, and by the accompanying drawings, that I dispense with the screw-plug referred to in my Letters Patent above named, and apply the nut N directly upon the cylindrical end g ot' the skein; consequently I am enabled to leave this end open, which will prevent the wooden axle-arm G from injury by dry-rot.

In practice the meeting edges of the skein need not be welded, except at the points g g where the screw is applied.

What I claim as my invention, and desire to secure by Letters Patent as an improvement on my invention patented May 1, 1861, isv The screw-thread g, formed upon the cylindrical en ofthe axle-skein, substantially inthe manner and for the purpose herein set forth.
