Improvements in or relating to Means or Apparatus for Turning the
Journals of Axles, Crank-pins, and the like.
I, CHARLES HENRY LAVERICK, of The Villas, Fall Lane, Ardsley, near Wake-
field, in the County of York, Engineer, do hereby declare the nature of this
invention to be as follows:-
This invention relates to a tool for use in turning up the journals of axles,
crank pins, and the like, of, say, a locomotive or stationary engine, after the
same have become worn, or out of shape. And its object is to provide an adjust-
able tool that may be used for the said purpose without removing the journal
or crank-pin out of position or place.
According to this invention the tool or cutter is composed of a ring or clamp
formed in one or more parts. When made in more than one part, the various
portions may be suitably secured together, say, for example, by bolts and nuts.
The inner diameter of the ring or clamp is made larger than the diameter of
the journal or crank-pin, or the like upon which it has to operate.
The outer periphery of the ring or clamp may, when used as a hand tool, be
armed with any desired number of handles, say, for instance, four, for rotating
purposes.
But the tool may also be arranged, if desired, to be operated or driven by
power such as, say, compressed air or steam, imparted directly thereto, or conveyed
thereto by means of one or more shafts and belts or it or their equivalents.
The faces or sides of the ring or clamp may also be armed with any desired
number of set screws for adjusting it laterally.
On the inner periphery of the ring or clamp are provided a number of rollers
mounted in suitable carriers arranged to work in slots, or recesses, or guides
formed in or on the ring or clamp for their reception. Each roller and its
carrier may be capable of adjustment to and from the periphery of the journal,
or crank-pin, or the like being operated upon by means of a set screw or its
equivalent. The rollers are employed for centreing the ring or clamp on to the
journal or crank pin, or the like.
At one or more points on the inner periphery of the ring or clamp and across
the same may be provided one or more recesses in which is or are mounted in
a suitable carrier or carriers one or more cutters of any suitable construction,
or any other tool or tools such as, say for example, a milling tool or cutter.
For
strengthening purposes one or more projections may be provided on each side
of the ring or clamp against which the cutter or cutters or tool or tools work or
impinge. Each cutter or tool is preferably arranged to work in a bridge piece
which is made to span the outer periphery of the ring or clamp and it is con-
nected to the bridge piece by means of links and pins. The ends of the bridge
piece are adapted to receive the cutter or cutting tool.
The cutter or cutting tool is adjusted to its work by means of one or more,
say, for example, two, set-screws arranged to pass through the ring or clamp and
to act on the cutter or cutting tool. In order to prevent the cutter or cutting
tool following the path of a worn or out of shape journal, or crank-pin, or the
like, around each adjusting screw is placed or mounted a helical spring by the

page_text: tension of which on the bridge piece the tendency will be to withdraw the cutter
or cutting tool from the periphery of the journal or crank-pin operated upon,
whilst the cutter or cutting tool will be kept to its work by the adjusting
screws.
By setting or adjusting the cutter or cutters or cutting tool or tools to remove
the protruding portions of the worn or out of shape journals, or crank-pins, or
the like, the latter may be turned perfectly true and circular.

Improvements in or relating to Means or Apparatus. for Turning the
Journals of Axles, Crank-pins, and the like.
"
I, CHARLES HENRY LAVERICK, of The Villas, Fall Lane, Ardsley, near" Wake-
field, in the County of York, Engineer, do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:.
This invention relates to a tool for use in turning up the journals of axles,
crank-pins, and the like, of, say, a locomotive or stationary engine, after the
same have become worn, or out of shape. And its object is to provide an adjust-
able tool that may be used for the said purpose without removing the journal
or crank-pin out of its position or place.
In the drawings hereunto annexed:-
Fig. 1 is a front elevation, and Fig. 2 a plan looking at the bottom of a hand
tool constructed according to this invention.
Fig. 3 a front elevation of the same tool arranged to be driven by power.
Fig. 4 a plan of same with the upper portion removed.
Figs. 5 to 12 are respectively elevations and sections of details.
Like parts in all the views are marked with similar letters of reference.
The tool or cutter is composed of a metal,-such as, say, wrought or cast iron
or steel, ring or clamp, hereafter termed a clamp A, formed in one or more
parts. In the drawings the clamp A is shown to be made in two parts. When
the clamp A is made in more than, say, two parts, the various portions may
be suitably secured together, say, for example, by bolts and nuts a. The inner
diameter a¹ of the clamp A is made larger than the diameter of the journal or
crank-pin, or the like upon which it has to operate.
The outer periphery of the clamp A may, when used as a hand tool, as at
Fig. 1, be armed with any desired number of handles B, say, for instance, four,
for rotating purposes, which may be lengthened or extended by means of the
removable arms B₁, shown in dotted lines at Fig. 1, and in full lines at Figs. 11
and 12. The removable arms B are provided with sockets b arranged to fit the
handles B and to be secured in position thereon by the set screws b.
But the tool may also be arranged, if desired, to be operated or driven by power,
as at Fig. 3, such as, say, compressed air or steam, imparted directly thereto, or
conveyed thereto by means of one or more shafts and belts or it or their
equivalents.
In the drawings the clamp A is shown armed with a spur wheel A¹ of larger
diameter and connected by its armis A2 so as to form a portion of the clamp A
as shown at Fig. 3. A spur pinion C, mounted on a shaft D, is made to gear
with the wheel A' for rotating purposes.
Each face or side a² of the clamp A is also armed with any desired number
of set screws a³-four on each side are shown-for adjusting it laterally.
On the inner periphery a¹ of the clamp A are provided a number of rollers E
mounted in recesses (as shown at Figs. 9 and 10) in suitable carriers F in, say,

page_text: U form, arranged to span or embrace the sides a² of the clamp A as shown at
Fig. 4, so that its roller E will project above the inner periphery a¹ of the clamp A
and at or about a right angle to its sides a³, and to work in slots, or recesses a*,
or guides formed in or on the clamp for their reception. Each roller E and its
carrier F is capable of adjustment to and from the periphery of the journal, or
crank pin, or the like being operated upon by means of a set screw f as shown.
The rollers E are employed for centreing the clamp A on to the journal or
crank pin, or the like.
At one or more points on the inner periphery a¹ of the clamp A and across
the same may be provided one or more recesses a³,-one recess is shown in the
drawings with a clearance for cuttings or turnings between two of the centreing
rollers E, but the number of recesses as may be increased as circumstances
require, in which is (or are) mounted in a suitable carrier (or carriers) G one
or more cutters H of any suitable construction.
In the drawings one cutter H is shown in Ụ form (see Figs. 7 and 8). The
cutting edge is connected to the end or upright pieces h¹ which are made to
span or embrace the sides a² of clamp A (see Fig. 4) whilst its cutting edge h
projects above the inner periphery a¹ of the clamp, and at or about a right angle
to its sides a².
For strengthening purposes one or more projections I is or are provided on each
side a of the clamp A against which the cutter (or cutters or tool or tools) H
bear or impinge. Each cutter H (or tool) is connected to a bridge piece J, which
is made to span the outer periphery a* of the clamp A and the cutter is connected
to the bridge piece by means of links K and pins L. Or the ends of the bridge
piece may be adapted to receive the cutter or cutting tool.
The cutter H (or cutting tool) is adjusted to its work by means of one or more,
say, for example, two, set screws M arranged to pass through the clamp A and
to act upon the inner portion h of the cutter (or cutting tool) H. In order to
prevent the cutter H (or cutting tool) following the path of a worn or out of
shape journal, or crank-pin, or the like, around each adjusting screw M is placed
or mounted a helical spring N interposed between the underside of bridge piece J
and the outer periphery a* of the clamp A by means of the springs N, the
tension of which on the bridge piece J will tend to withdraw the cutter H (or
cutting tool) from the periphery of the journal or crank-pin operated upon, whilst
the cutter or cutting tool will at the same time be kept to its work by the
adjusting screws M, thus removing any protuberance or irregular conformation
of the article operated upon.
By setting or adjusting the cutter H (or cutters or cutting tool or tools) to
remove the protruding portions of the worn or out of shape journals, or crank
pins, or the like, the latter may be turned perfectly true and circular.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
-
A tool for turning the journals of axles, crank-pins, and the like, capable of
being actuated by hand or power substantially as described, consisting of a
clamp formed in parts bolted together, armed at the sides with centreing screws,
and having a number of centreing rollers and cutters or tools mounted adjustably
as described in carriers so as to project across its inner periphery, and the means
for actuating the clamp, all arranged, combined, and operating substantially
as herein set forth and as illustrated.
