ANDREW F. SMIITH, OF AIKEN, TEXAS.
IMPROVEMENT IN REVERSIBLE AXLE-SKEINS.
Specification forming part of Letters Patent No. 125,762, dated April 16, 1872.
Specification describing a new and Improved
Reversible Axle-Skein, invented by ANDREW
F. SMITa, of Aiken, in the county of Bell and
State of Texas.
My invention consists of cast-metal axle-
skeins fitted on the axles, whether of wood or
iron, so that they can be turned from time to
time, as they wear away, to remove the worn
place from the wearing position and bring a
part not worn thereto. The invention also con-
sists in pinning the skein to the axle, to re-
lieve the linch-pin or nut from the end thrusts
of the skeins.
Figure 1 is partly a side elevation and part-
ly a sectional elevation of an axle with skeins
applied according to my improvement, and
Fig. 2 is a transverse section on the line x x
of Fig. 1.
Similar letters of reference indicate corre-
spouding parts.
A is the axle. B is the skein. C is the pin
for securing the skein on the axle to prevent
it from thrusting against the linch-pin or nut
D too hard. The hole through the skein is
made square or octagonal, and the axle is sim-
ilarly formed, so that neither can turn inde-
pendently of the other, and the skein will re-
main on the axle as it is adjusted; the object
being to shift the skein a quarter or half way
round as it wears away, thus practically re-
newing the skein without cost, which can be
done to advantage at least four times before the
skein is wholly worn out, whereas the skein is
worthless after a certain amount of wear in
one place when arranged in the common way.
The pin C will be fitted in so as to be readily
removed for so shifting the skeins and the
skeins will have two or more holes through
them to allow the pin to be used in all the po-
sitions of the skein.
Having thus described myinvention, I claim
as new and desire to secure'by Letters Pat-
cut-
As an article of manufacture, an axle-skein,
B, polygonal in form and diagonally apertured,
as described, so that the bearing-surface can
be changed and the wear taken on different
parts of its perimeter.
