AXLE-SKEIN.

SPECIFICATION forming part of Letters Patent No. 374,473, dated December 6, 1887. Application filed August 22, 1887. Serial No. 247,566. (No model.)

12) all whom it may concern:

Beit known that I, EDMUND N. HATCHER, of Columbus, in the county of Franklin and State of Ohio, have invented a new and Irnproved Axle-skein, of which the following is a full, clear, and exact description.

My invention relates to an improvement in axle-skeins, and has for its object to provide a device which may be readily manufactured and in which angular indentures in the edge surfaces are avoided in cutting the blank, thereby avoiding danger of cutting too deep with the ends of the shears and weakening the skein by furnishingastarting-pointforabreak, and also wherein the skein will take an axle without trimming the same, and fully protect the wood at the point of intersection with the skein and a distance beyond the same.

The invention consists in forming an axle skein of a single piece of metal and in cutting the blank in such manner that angular recesses in the edges are avoided, and also in the details of construction, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a side elevation ofthe axle-skei'n. Fig. 2 is a central longitudinal section through the same. Fig. 3 is a plan view of the blank. Fig. 4 is a transverse section through the enlarged portion of the skein, and Fig. 5 is a transverse section through the inner end.

It is the object of the present invention to so shear the shape or blank as to entirely avoid shearing an Lshaped recess in the same, or any recess wherein the shears points are liable to start splitting, thereby weakening and rendering possible a snap, split, or break under heavy strain or in trying positions. To that end the blank A is cut square at the ends a and a, and from the outer edges of the front end, a, the sides are cut in a straight line toa point, m at the front of the center, the said lines being projected outwardly in opposite directions toward the rear end, whereby the inclined side edges, I), are produced. From the point a the front side edges are curved outward to produce a slight concavity, 12', ten ininating at or near the centerof the blank,

and the metal at the center is cut straight across a short distance, then downward and inward with a full curve, d, and outward to the rear end in a straight line, d, thesaid lines 01 having an inclination from their point of junction with the curve 01 inwardly and rearwardly, the corners produced by their union with the rear end being beveled off, as shown at d, Fig. 3. Thus the blank comprises a wide front end, central side wings or extensions, D, and a reduced rear end.

In further carrying out the invention the side edges of the blank are bent upward to ward each other and the edges from the outer end of the curve (I extending forward are welded or otherwise firmly secured one to the other. .As a result of the attachment :1 round tapered spindle portion, D, is produced,upon which the .wheel or hub-box is to revolve. At the butt or inner end, 6, of the spindle a metallic collar or band, E, is seen red by welding or shrinking, and to the rear of the collar E an upwardly-curved bonnet, F, is formed, extending from the axle-butt e to a point, 0, near the center and horizontal to the extreme up per point, 6 as shown in Figs. 1 and 2, the said bonnet commencing round at c and ending at e in an oblong or 0 shape, asillustrated in Fig. 4. The rear end of the skein-that is, from the central point, e' t0 the end aforms an integral truss-extension, F, curving upward to meet the bonnet, and to the rear of the curve the said truss-extension is substantially Ushaped in cross-section, as shown in Fig. 5. The skeins usually break at 6 but my skein, made from a plate or blank having the downwardcurved shear d, causes the extension to act as a brace, that cannot do else than greatly re-enforee the weak point and act as a truss between e and a.

Ourvinglthe bonnet upward, as shown and described, admits of the admission of a greater amount of wood or timber than heretofore, and by reason of the peculiar shape of the truss the axle need not be hewed from its sawed shape, whereby it is weakened, and the oblong shape of the bonnet will cause the use of sufficient timber to make the axle equal to almost any emergency.

By making my skein without a short bevel I avoid cutting notches or making a beveled hump, and am enabled to make a sheetmetal skein with an extension sleeve thoroughly braced from end to end and entirely free from angular cuts, which often cause a split or break and weaken the skein more at one point than at another.

The gradual upwardly extending bonnet commencing at 6 when the collar is made fast enables me to do away with cutting the usual notch or bead, forming a hump to act as a hub or box rest. v

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The blank A, for a thimble-skein, herein shown and described, having its sides formed with opposing wings D D, inclines b b d d at opposite ends of its sides, and the curved or rounding portions 1/7) and d cl between the wings D D and the inclines Z) Z) and d (1, respectively, substantially as set forth.

2. An axle-skein formed of a single piece and with a round tapering spindlesection, D, an oblong bonnet, F, curved gradually from the point e to the point e and horizontally to the extreme upper point e, and the rear trussextension, F, curving upward to the bonnet, as at d 65, substantially as set forth.

8. An aXle-skein made from a single piece of metal and composed of a tapering spindlesection, an upwardly-extending and integral hood circular in cross-section at its intersection with the spindle and oblong at its outer end, and a rear trussextension U-shaped in cross-section, united with the hood by a curved edge surface, whereby angular recesses are avoided, as and for the purpose set forth.

4. An aXle-skein made from a single piece of metal and composed of a tapering spindlesection, an upwardly-extending anddntegral hood circular in cross-section at the intersection with the spindle and oblong at its outer end, a collar secured to the spindle at the intersection of the hood, and a rear truss-extension U-shaped in cross-section, having its in ner side edges concaved at their union with the hood, as and for the purpose herein specified.
