WILLIAM CLARK of the firm of A. M. and W. Clark of 53 Chancery Lane
in the County of Middlesex, Patent Agents, "IMPROVEMENTS IN. AXLES FOR
VEHICLES [A communication to him from abroad by John Henry. Huyler, of
Tenafly, in the County of Bergen and State of New Jersey-United States of
America.]
The object of this Invention is to increase the durability of vehicle axles and
facilitate the repairing of the said axles when worn.
The Invention consists in a vehicle axle constructed with an adjustable bushing
secured in place by a tubular nut and provided with grooves and passages to
receive oil and an adjustable band provided with set screws and an oil hole whereby
the bushing can be adjusted as each side becomes worn and can be readily supplied
with oil.
The body of the axle is made square and its arm or journal is made round and
tapered and has a screwthread upon its end in the ordinary manner. The shoulder
of the axle where it passes from a square to a round form is rounded for con-
venience in casting the bushing. The bushing is cast with its interior of such a
shape and size as to fit upon the journal of the axle and the outer end of the square
part of the said axle, so that the said bushing cannot turn upon the axle. To
prevent the forward end of the bushing from turning upon the journal of the axle,
the forward part of the said axle at the base of the screwthread is made square
and the inner surface of the forward end of the bushing is made square to fit upon
it so that it will be impossible for the bushing to be twisted, and thus injured

page_text: should it heat and bind in the thimble skein. The bushing is made shorter than
the arm of the axle and is kept in place by a tubular nut which is flattened upon
its opposite sides to allow it to be readily screwed on and off. The bushing and
nut are made of such a length that the outer end of the said nut will be flush with
the outer end of the thimble skein which fits upon the bushing and is designed to
be secured to the hub of the wheel in the ordinary manner. The inner end of the
bushing is enlarged to serve as a collar to the axle, and has a ring groove formed
in its shoulder to receive the rebated end of the thimble skein, and is rebated so as
to overlap the end of the thimble skein. The rebated end of the skein does not
extend to the bottom of the groove so that the inner part of the said groove may
serve as an oil reservoir. If desired a leather washer can be interposed between
the shoulders of the bushing and skein to prevent oil from escaping and to
lessen the friction between the said shoulders. There is an annular groove in the
outer surface of the rear part of the bushing to serve as an oil reservoir, and from
the forward side of the groove holes lead from the bottom to the bottom of the
other groove to serve as passages for the oil. The first groove is covered by a
band which is kept in place by two conical pointed set screws which pass through
the said band, enter the groove, and bear against the bottom of the same, the
conical shape of the points of the screws preventing them from obstructing the
passage of oil through the groove. The. holes in the groove are formed directly
opposite the centres of the flat sides of the axle so that whichever side of the
bushing be upward, one of the holes will also be upward so that oil can be poured
into it through a hole in the band which is formed in such a position that when
turned to either side of the holes, it will be over a solid part of the bushing so that
oil cannot escape through it. The band can be readily turned by loosening the
set screws.
In order to make the reservoir oil tight, the bushing is furnished with grooves
in the outer surface of its end portion to receive packing and thus prevent escape
of oil between the band and the bushing.
With this construction when the lower side of the bushing becomes worn, the
same can be removed, turned one half or one quarter around, and replaced, so that
the wear will come in a new place. When all four sides of the bushing become
worn, the said bushing can be thrown to one side and replaced by a new bushing
at a trifling cost, the journal of the axle being always protected from wear.
The skein and with it the hub of the wheel are kept in place upon the bushing
by a cap nut, and the escape of oil is prevented by a leather washer kept in place
by said nüt.

WILLIAM CLARK of the firm of A. M. and W. Clark of 53 Chancery Lane
in the County of Middlesex, Patent Agents, "IMPROVEMENTS IN AXLES FOR
VEHICLES." A communication to me from abroad by John Henry Huyler of.
Tenafly in the County of Bergen and State of New Jersey, United States of
America.
The object of this Invention is to increase the durability of vehicle axles and
facilitate the repairing of the said axles when worn.
The Invention consists in a vehicle axle constructed with an adjustable bushing
secured in place by a. tubular nut and provided with grooves and passages to
receive oil and an adjustable band provided with set screws and an oil hole whereby
the bushing can be adjusted as each side becomes worn and can be readily, supplied
with oil as will be hereinafter fully described.
In the accompanying drawings, Figure 1 is a sectional side elevation of the
improvement. Figure 2 is a sectional end elevation of the same taken through the
line xx Figure 1 and looking to the right. Figure 3 is a sectional end elevation.
of the same taken through the line y-y Figure 1 and looking to the left. Figure 4
is a sectional end elevation of the same taken through the line - Figure 1.
Figure 5 is a sectional end elevation of the same taken through the line ww
Figure 1. Figure 6 is a side elevation of the inner end of the adjustable bushing.
Similar letters of reference indicate corresponding parts in all the figures:
A represents an axle, the body of which is made square and its arm or journal
is made round and tapered, and has a screwthread upon its end in the ordinary
manner. The shoulder of the axle A where it passes from a square to a round
form is rounded, as shown in Figure 1, for convenience in casting the bushing B.
The bushing B is cast with its interior of such a shape and size as to fit upon the
journal of the axle and the outer end of the square part of the said axle, so that .
the said bushing cannot turn upon the axle. To prevent the forward end of the
busbing B from turning upon the journal of the axle A, the forward part of the
said axle at the base of the screwthread is made square and the inner surface of
the forward end of the bushing is made square to fit upon it as shown in Figures
1 and 5, so that it will be impossible for the bushing to be twisted and thus injured
should it heat and bind in the thimble skein. The bushing B is made shorter than
the arm of the axle A and is kept in place by a tubular nut C which is flattened
upon its opposite sides to allow it to be readily screwed on and off, as shown in
Figure 4. The bushing B and nut C are made of such a length that the outer end
of the said nut will be flush with the outer end of the thimble skein D which fits
upon the bushing B and is designed to be secured to the hub of the wheel in the
ordinary manner. The inner end of the bushing B is enlarged to serve as a collar
to the axle and has a ring groove E formed in its shoulder to receive the rebated
end of the thimble skein D and is rebated so as to overlap the end of the thimble
skein, as shown in Figure 1. The rebated end of the skein D does not extend to
the bottom of the groove E, as shown in Figure 1, so that the inner part of the
said groove may serve as an oil reservoir. If desired a leather washer F can be
interposed between the shoulders of the bushing B and skein D to prevent oil from
escaping and to lessen the friction between the said shoulders. In the outer surface
of the rear part of the bushing B is formed an annular groove G to serve as an oil
reservoir, and from the forward side of which holes H are formed leading from the

page_text: bottom of the groove G to the bottom of the groove E to serve as passages for the
oil. The groove G is covered by a band I which is kept in place by two conical
pointed set screws J which pass through the said band I, enter the groove G, and
bear against the bottom of the said groove the conical shape of the points of the
screws J preventing them from obstructing the passage of oil through the groove G.
The holes H are formed directly opposite the centers of the flat sides of the axle A
so that whichever side of the bushing B be upward, one of the holes H will also.
be upward so that oil can be poured into it through a hole I' in the band I which
is formed in such a position that when turned to either side of the hole.H it will
be over a solid part of the bushing B so that oil cannot escape through it. The
band I can be readily turned by loosening the set screws J. In the outer surface
of the end part of the bushing B upon opposite sides of the groove G, are formed
grooves M, as shown in Figures 1 and 6, to receive packing to prevent oil from
escaping between the band I and the said bushing and thus make the oil reservoir
oil tight
With this construction, when the lower side of the bushing B becomes worn
the same can be removed, turned one half or one quarter around, and replaced,
so that the wear will come in a new place. When all four sides of the bushing B
become worn, the said bushing can be thrown to one side and replaced by a new
bushing at a trifling cost, the journal of the axle being always protected from wear.
The skein D, and with it the hub of the wheel, are kept in place upon the bushing B
by a cap nut K, and the escape of oil is prevented by a leather washer L kept in
place by the said nut K.
Having described the nature of the said Invention and the manner of performing
the same, I would observe that I am aware that it is not new to use a detachable
replaceable bush or sleeve within an axle-box, but what I claim as the Invention
to be protected by the hereinbefore in part recited Letters Patent is.
1. The combination of an end threaded axle A, a thimble skein D, a bushing B,
an end nut K, a washer L, and an oppositely flattened tubular nut C, the thimble
skein being shorter than the axle and the bushing being shorter than the thimble
skein, as shown and described.
2nd A vehicle axle constructed substantially as herein shown and described, and
consisting of the axle A, adjustable bushing B having grooves E G and passages H,
the adjustable band I having set screws J and oil hole I' and the tubular nut C,
as set forth.
3rd. In a vehicle axle, the combination with the bushing B having groove E,
of the thimble skein D having rebated inner end, substantially as herein shown
and described whereby the said groove is made to serve as an oil reservoir, as
set forth.
4th. In a vehicle axle the combination with the bushing B having grooves E G
and passages H, of the adjustable band I having oil hole I and set screws J,
substantially as herein shown and described, whereby. the said bushing can be
readily supplied with oil and the escape of oil will be prevented, as set forth.
In Witness whereof I the William Clark have hereunto set my hand
this second day of April, A.D. 1883.
