COMPLETE SPECIFICATION filed by the said Albert Riche at the Office of
the Commissioners of Patents on the 5th April 1882.
ALBERT RICHE Engineer of Jeumont Departement du Nord France temporarily
of Effra Road Brixton in the County of Surrey, "IMPROVEMENTS IN THE ROLLING
OF BARS OF STEEL, IRON OR OTHER METAL TO BE AFTERWARDS WORKED UP WITHOUT
WELDING INTO AXLE GUARDS WAGGON COUPLINGS AND ARTICLES OF A SIMILAR
OUTLINE AND IN MACHINERY FOR THE SAME.'

According to the ordinary processes of manufacturing axlo guards, the maker is
obliged to weld together three or four pieces of iron of suitable dimensions. When
only two welds are made they occur at the junction of the wings with the horns a, b
fig. 4 when there are three the third is made at the double or arch of the horn
plate c fig. 4.
The first mentioned welds a and b are very difficult to make and frequently the
work is passed as sound when there are flaws in the welding. This class of work
requires workmen of the first skill in their trade whence, it follows as a natural
consequence that the greater the difficulty in making a sound axle guard the higher
is the class of handicraft skill required.
The object of my Invention is the production of bars of iron steel or other metal
of such shape and dimension that the working them up into any determined type of
axle guard or other article of similar or analogous outline may be accomplished as
cheaply as possible and without welding.
To achieve this I start by producing a bar B A C or a series of bars A A A as
represented in Plan in fig. 3. Each bar is slotted right through it, but not for its
whole length as shewn at R.

page_text: Other methods of producing these bars is as follows. We roll in the ordinary
way and of the desired size a bar which is passed through a pair of rolls of a
special construction represented in side elevation in Fig. 1 and in end elevation in
fig. 2. These rolls are mounted and driven in any convenient way. The working
surfaces are of steel. Each roll T is built up of several discs of cast or wrought
iron or steel which are held together by bolts b or any other suitable equivalent.
One of the discs L in the upper roll is made with a circular projection extending
nearly round it. This is clearly seen in Fig. 2. The length of this projection
represents that of the slot R in the bar fig. 3. The length of the slot to be made in
a bar can be varied at will by simply replacing the disc L by another of another
diameter and consequently with a projection of a different length. The width of
the slot is always that of the disc L.
The lower roll has a groove E in its periphery, the projection of the disc L enters
this groove as the rolls are revolved producing the groove R by cutting a piece out
of the bar as the latter passes through the rolls. The bar as it leaves the rolls
passes between suitable guides of any convenient shape which prevent it from
being carried round either roll.
.
In the act of bending or curving the horn plate of an axle guard or of any other
piece of a similar shape, the inside edge is thickened in consequence of a massing of
métal thereat, while the outer side is thinned in a corresponding degree. To obviate
this inequality in thickness the bar is rolled with its inside edge slightly feathered
i.e. thinner than the outer one so that after the bending or curving the thicknesses
of the opposite edges shall be alike.
I always leave plenty of metal in the slotted bar at those points where the
wings of the axle-guard spring from the horns. With this view the upper roll is
indented at the necessary points in its periphery more or less deeply according to
the special requirements of the case.
A consideration of fig. 3 will shew how the working up or shaping of the
axle-guard from the slotted bar is accomplished. The side which is intended to.
produce the wings b. d. a. f. fig. 4 is cut at the proper point, the parts are bent
outwards at the proper angle and their ends shaped as may be required and lastly
the horn-plate is bent in any convenient way.
I do not confine myself to the use of flat bars my invention is equally applicable
to any other section of bar see figs. 5, 6, 7, 8 and 9.
In making waggon couplings or other objects of a like shape I proceed as above
described for producing the slotted bar using discs and rolls of a suitable diameter,
and with their periplieries turned (and indented when necessary) to produce the
required shape, see fig. 10.
Having now described in detail my invention and the manner of carrying the
same into effect I wish it to be distinctly understood that I consider new therein is
not the particular shape of the articles made but what I do claim is
1. The rolls figs. 1 and 2 with a disc L, carrying a circular projection, the other
roll. having a corresponding groove E as and for the purposes described and
substantially illustrated in the drawings.
2. The method of producing without welding articles in iron steel or other metal
by using a pair of rolls made according to the above description and drawings and
the articles so produced.
