We, JOHN DONNELLY, of 21 Parliament Street, in the County of Middlesex,
Engineer, WILLIAM MCLAREN of Moorgate Works Moorfields in the County of
Middlesex, Engineer and AMBROSE TRASK of Sandbourne Road, Brockley in the
County of Kent, Engineer, do hereby declare the nature of this invention to be as
follows:-
Axle boxes for railway carriages and other vehicles have been cast; also they have
been made of wrought metal in several parts such parts being forged to the
required shape by steam hammers, welded together in a mould or receptacle of the
required shape and afterwards machined and finished.
Now this invention has for its object to make axle boxes of a light description and
in a cheap and simple manner. For this purpose an axle box according thereto is
made wholly or partly of sheet metal of suitable thickness, by cutting and pressing
or stamping so as to draw and convert the sheet to the required form in suitable
dies actuated by hydraulic or other machinery; it may be by a steam hammer.
Such sheet metal axle boxes may be formed as described in parts of appropriate
shape that are afterwards fastened together by any suitable means such as rivets
or bolts; or in some cases an axle box may comprise an upper part of cast metal
and a lower part of sheet metal pressed or stamped and drawn to shape as described.
Dated this 16th day of March 1887.

page_text: New or Improved Manufacture of Axle Boxes for Railway
Carriages and other Vehicles.
We, JOHN DONNELLY, of 21, Parliament Street, in the county of Middlesex,
Engineer, WILLIAM MCLAREN, of Moorgate Works, Moorfields, in the county of
Middlesex, Engineer, and AMBROSE TRASK, of Sandbourne Road, Brockley, in the
county of Kent, 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 :-
Axle boxes for railway carriages and other vehicles have been cast; also they have
been made of wrought metal in several parts, such parts being forged to the required
shape by steam hammers, welded together in a mould or receptacle of the required
shape and afterwards machined and finished.
Now this invention has for its object to make axle boxes of a light description and
in a cheap and simple manner. For this purpose an axle box according thereto is
made wholly or partly of sheet metal of suitable thickness, by cutting and pressing or
stamping, so as to draw and convert the sheet to the required form in suitable dies
actuated by hydraulic or other machinery; it may be by a steam hammer. Such
sheet metal axle boxes may be formed as described in parts of appropriate shapo that
are afterwards fastened together by any suitable means such as rivets or bolts; or in
some cases an axle box may comprise an upper part of cast metal and a lower part of
sheet metal pressed or stamped and drawn to shape as described. And in order that
the manner of carrying our invention into practice may be readily understood,
reference is made to the accompanying drawings in which
Fig. 1 represents one form of a sheet metal plate for conversion into an axle box
according to this invention.
Fig. 2 is a plan of one of the stamps or dies used for subjecting the sheet metal
plate to the first stamping or pressing operation.
Fig. 3 is a longitudinal vertical section of a pair of stamps or dies with a sheet of
metal between them the form of the dies and plate corresponding to the section of the
stamp or die taken in the line A, B, Fig. 2.
Fig. 4 is a vertical section in the line CD Fig. 5; and
Fig. 5 a plan or top view illustrating the second operation for converting the plate
nto an axle box.
Figs. 6, 7, and 8 are respectively a vertical section, a horizontal section and a
transverse section of a complete axle box constructed according to this invention,
with an axle journal located therein. The sheet of metal to be operated upon is of
approximately rectangular form as shown in Fig. 1, parts of the plate corresponding
with the two areas a, b, c, d, being cut away.
In the first operation the sheet metal plate is subjected to a stamping or pressing
operation between stamps or dies 1 and 2 whereby it is formed with two sets of ridges
or corrugations 3, a recessed part 4, upwardly inclined parts 5, 5, downwardly
inclined parts 6, 6, and raised bosses or parts 7, 7, (Fig. 4), the acting surfaces of the
stamps or dies being made of corresponding form. The plate thus formed is then

page_text: subjected to a second operation in which it is placed upon a block or die 8, the upper
surface of which is formed to correspond with the parts 4, 5, 6, and 7 of the plate.
Two opposite sides of the block or die 8 are flat, and the other two opposite sides are
each provided with vertical ribs or projections 9. 10 is a bolster or die plate formed
with an opening, the internal configuration of which corresponds in form with the
exterior outline in a horizontal direction, of a complete axle box and as shown in plan
(Fig. 5). This bolster is placed upon the plate, which is preferably held upon the
block or die 8 by a correspondingly formed die or pressure plate. The bolster is then
forced downwards by suitable means such as a hydraulic press whereby the side
portions of the plate are forced or drawn down to form the four sides of the box, the
corrugations 1 in the plate being so arranged with reference to the block or die 8 as
to form by the action of the projections 9 on such block or die and the adjacent parts
of the bolster, projecting portions 1*, the space between each pair of which forms a
groove 11 that serves as a horn plate or axle guard guide. During this operation,
the two sets of edges a, e, and d,f of the plate are brought together, and each set of
edges a, b, and d, e, are brought against the adjacent edge b, c. These adjacent edges
of the plate are afterwards united by welding in a manner well understood.
The recessed part 4 serves for the reception of the buckle of a spring, and the
inclined parts 5, 5, as bearings for the adjacent portions of such spring. The inner
side 12 of the box is cut away at 13 for the entrance of the journal end of an axle.
14 is a second stamped plate secured in any suitable manner-it may be by
welding to the upper part of the box-and serving in conjunction therewith as a
grease box and also as a bearing for the reception of the brass or bearing for the
axle journal; it is formed by stamping or pressing in dies in a similar manner to
the first plate and is provided with a hole for the passage of grease. Part of the
side 12 may be flanged outward as shown at 15 and to it part of the stamped plate 14
may be welded. 16 is a third stamped plate secured to the lower part of the axle box
in any convenient manner and serving as a keep therefore. The rear inclined part 4
at the top of the box is in the example shown cut away for the insertion of grease and
the opening thus formed is provided with a hinged cover shown in dotted lines.
By providing the dies with additional ribs or projections as shown in dotted lines in
Fig. 2, the plate will be formed with additional corrugations which when the plate is
subjected to the second operation will be formed into additional grooves 17 17 as
shown in fig. 7 and which will serve for the reception of a dust guard.
For this purpose the internal configuration of the bolster 10 must be corre-
spondingly modified.
Axle boxes may in some cases he formed with an upper part of cast iron and a
lower part of sheet metal which is formed with grooves for the reception of a horn
plate by stamping or pressing operations the two parts being connected by any
suitable means as for instance by forming the adjacent portions with lugs, and
securing these by screw threaded bolts and nuts.
It will be obvious that axle boxes differing somewhat in form from that shown may
be constructed in accordance with this invention.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, we desire to have it
understood that we do not lay any general claim to the manufacture of axle boxes
of wrought iron but that our invention has reference essentially to the manufacture
of axle boxes or part boxes from sheet metal by stamping or pressing to shape in
such a manner as to obviate the necessity for machining, as distinguished from the
forging of such boxes or part boxes out of pieces of metal not in the form of sheets
and which necessitate machining to produce the finished box or part box as for
instance in order to make the grooves for axle guards or horn plate, the seats for
springs, and the grooves for dust guards, and we hereby declare that what we
claim is:-
1. The manufacture of axle boxes or part boxes with grooves for axle guards in the
improved manner hereinabove described, that is to say, by submitting sheet metal of

page_text: uniform thickness to successive stamping or pressing operations and thereby pro-
ducing without machining the required form of axle box or part box with its grooves
as above set forth.
2. An axle box with grooves for axle guards formed from sheet metal of uniform
thickness by pressing or stamping as above set forth.
3. An axle box with grooves for dust guard and for axle guards and seat for
spring, the whole made of sheet metal by stamping or pressing substantially in the
manner hereinabove described.
