WILLIAM MALAM, of Edgemoor, Newcastle County, State of Delaware, United
States of America, Boiler Maker, do hereby declare the nature of this invention to be
as follows:-
My Invention consists of improvements in the construction and method of appli-
cation of detachable journals for the axles of railroad cars and other vehicles and
relates partly to a former invention for which I obtained Letters Patent bearing the
number 13,028 and dated the 27th day of October, 1885. The main feature of my
said invention was the combination of the body plate or plates of a car wheel with an
axle having a wheel hub formed integral therewith and presenting a seat or seats to
which the body of the wheel was bolted. In the axle illustrated in the drawings
accompanying the specification of the said former invention the journal formed part
of the axle, but it is advisable in many cases, to make the journal independent of and
detachable from the body of the axle, so that it can be removed when worn or other-
wise defective, and be replaced by a new one, without discarding the entire axle. For
this reason, in constructing my present axle, I provide the body thereof with a Hange
and construct the journal with a corresponding flange which is secured to the flange
upon the axle by means of bolts which may also serve to secure parts of the wheel
borly. In order to assist these bolts in resisting the lateral and torsional strains to
which the journal is subjected, I provide the inner face of the flange upon the
journal with a dove-tailed rib or projection which is formed to suit a correspondingly
formed recess in the outer face of the flange upon the axle body, and thus pets as a
key. If considered to be desirable this arrangement of the said rib and recess may
be reversed that is to say, the rib may be formed on the flange upon the axle body

page_text: and the recess in the flange upon the journal or a separate key, adapted to recesses in
both flanges may be used, and where torsional strains only are to be resisted by the
key, the latter need not be dove-tailed or undercut. This part of my invention is
applicable in the construction of axles not otherwise formed in accordance with my
said former invention. The construction of the wheel may also be modified in other
respects, without departing from the main feature of my invention as for example I
may dispense with the key and arrange for the securing bolts to pass through the
plates of the wheel body as well as through the said flanges so as to clamp all the said
parts together.

page_text: 1 WILLIAM MALAM of Edgemoor Newcastle County, State of Delaware United
States of America, Boiler Maker, 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 and accompanying drawings:-
My Invention consists of improvements in the construction and method of appli-
cation of detachable journals for the axles of railroad cars and other vehicles and
relates to a former invention for which I obtained Letters Patent bearing the number
13,028, and dated the 27th day of October 1885. The main feature of my said
said invention was the combination of the body plate or plates of a car wheel with an
axle having a wheel hub formed integral therewith and presenting a seat or seats to
which the body of the wheel was bolted. In the axle illustrated in the drawings
accompanying the specification of the said former invention the journal formed part
of the axle, but it is advisable in many cases, to make the journal independent of and
detachable from the body of the axle, so that it can be removed when worn or other-
wise defective, and be replaced by a new one without discarding the entire axle. For
this reason, in constructing my present axle 1 provide the body thereof with a flange
and construct the journal with a corresponding flange which is secured to the flange
upon the axle by means of bolts which may also serve to secure parts of the wheel
body. In order to assist these bolts in resisting the lateral and torsional strains to
which the journal is subjected, I provide the inner face of the flange upon the journal
with a dove-tailed rib or projection which is formed to suit a correspondingly formed
recess in the outer face of the flange upon the axle body, and thus acts as a key.
If considered to be desirable this arrangement of the said rib and recess may be
reversed; that is to say, the rib may be formed on the flange upon the axle body
and the recess in the flange upon the journal or a separate key, adapted to recesses in
both flanges may be used, and where torsional strains only are to be resisted by the
key, the latter need not he dove-tailed or undercut. This part of my invention is
applicable in the construction of axles not otherwise formed in accordance with my
said former invention. The construction of the wheel may also be modified in other
respects, without departing from the main feature of my invention.
And in order that my said invention may be properly understood I will now
proceed more particularly to describe the same with reference to the annexed two
sheets of drawings.
Fig. 1 (Sheet 1) is a cross section of my improved car wheel.
Fig. 2 is a view of the inner face of the wheel the axle A being shown in section at
the line 12 Fig. 1.
Figs. 3 and 4 illustrate the mode of attaching the journal B to the hub or flange a
of the axle A.
As clearly shown by the said Figs. the axle A is formed with a hub or flange a, a
similar and corresponding flango 6 being likewise formed on the journal B. The body
of the wheel is composed of annular plates. These plates are bolted to the

page_text: tyrej by bolts as shown. The inner edge of the plate is bolted to the flange a by
bolts y and the inner edge of the plate is secured to the flange b by bolts & which
also pass through both of the flanges a and b and unite the whole firmly together. In
order to assist the bolts d to resist torsional and disruptive strains, I render the con-
nection between the flanges a and b still more secure and rigid by forming upon one
of them say upon the the flange ba dove-tailed ribi which enters a correspondingly
formed recess m in the opposite flange a and acts as a key to connect the two flanges.
The flanges
a and b with their respective rib and recess are shown at Figs. 3 and 4 of
the drawings. The arrangement of rib and recess may if desired be reversed that is
to say the rib may be formed upon the flange a and the recess in the flange b; or a
separate key occupying recesses in both flanges may be used as shown at Fig. 7.
sheet 2 of the drawings or more than one such rib or key might be used. The dove-
tailed rib or key is preferred where it is required to resist longitudinal separation of
the parts but where torsional strains only are to be resisted the key or rib need not be
undercut or dove-tailed. The construction of the wheel may also be modified in other
respects without departing from the main feature of my invention. For instance in
Figs. 5 and 6 sheet 2 I illustrate a wheel and axle in which the key is dispensed
with and in which the inner plate of the wheel body is in the form of a disk the
central portion of which is clamped between the flanges a and b the outer plate fl
being clamped to the outer face of the said flange and both sets of securing bolts d
and passing through both plates and both flanges.
I
It will be evident that so far as concerns the use of the keys and ribs in connection
with the axle and detachable journal my invention is applicable to axles generally
and is not restricted to such axles as are constructed in accordance with my said
former invention or in accordance with the particular type hercin set forth.
I am aware that axles having detachable journals have been already used and
therefore I make no claim to a letachable axle per se neither do I claim the con-
necting of the flanges of the axle and journal of car wheels by bolts passing through
the wheel body, except in the case of double plate wheels.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed 1 declare that what I claim is :—
(1). The general arrangement and combination of parts composing a railway carriage
or car or other vehicle wheel substantially as described and shown in the respective
figures of the annexed drawings.
(2). In railway carriage, car, and other similar wheels and axles having detachable
journals, forming the axle and journal with flanges and connecting the said flanges
by means of a rib or key or of ribs or keys substantially in the manner herebefore
described and shown in combination with holding bolts applied in the manner set
forth and indicated.
(3). In wheels for railway carriages cars and other vehicles the combination of the
body portion of the axle and the detachable journal, both having flanges which unite
to form a wheel hub together with the inner and outer plates constituting the wheel
body and the bolts whereby the said body plates are secured to the wheel hub
some or all of such bolts also serving to secure together the flanges forming the hub
all substantially as hereinbefore described and shown.
