Improved Rolling Apparatus for the Manufacture of Horse-shoes,
also applicable to other purposes.
I CHARLES WILLIAM JAMES of James Brothers Limited Midland Horse Shoe
Works Bridge Street Northampton do hereby declare the nature of this invention to
be as follows:-
The object of my invention is to provide a means or arrangement of rolls by the use
of which the blanks from which horse shoes and other like articles are formed may
be rolled out and the hollows recesses indents grooves and the like formed therein
as the bar comes direct from the furnace instead of the shoe or other article having
to be stamped out of the metal in the ordinary manner involving the necessity of
a second heating in order to bend or form the blank to the desired shape.
In carrying out my invention I provide a pair of rolls so formed that in one
of these say the lower are formed grooves of suitable shape and depth to receive
the steel or other bar when coming hot from the furnace in one or more of these
grooves are projections or cores corresponding to the indents required to be left
in the blanks for various kinds of shoes or for other purposes and on the upper
roll are projecting flanges or beads for forming grooves or tailings on the said
blanks when required.
The rolls are made of such diameter as to suit the size of blank required to be made
and the grooves are stopped or terminated at intervals so that the blanks are cut or
nearly so at such points and the next blank may immediately commence to be formed
without waste of material at each revolution of the rolls.
If found necessary there may be grooves on both rolls or grooves and beads on
each roll as circumstances may require.
In order to ensure the exact coincidence of the requisite parts of the upper and
lower rolls form cogs or other interlocking devices thereon and the whole
arrangement may be driven by any suitable and well known gearing actuated by
motive power.
The rolls are so cut or cast that the lower one acting on the bar forms one
portion of the blank shoe and the upper roll the other and the blank having been
thus rolled out is at once placed on a shaping block another roll is passed over it
whilst hot and it is thus brought to the requisite curve or shape.

COMPLETE SPECIFICATION.
Improved Rolling Apparatus for the Manufacture of Horse-shoes,
also applicable to other purposes.
I, CHARLES WILLIAM JAMES, of James Bros. Limited, Bridge Street, Northampton,
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 :-
The object of my invention is to provide a simple and effective method of rolling
out from bars of metal the blanks from which horse shoes and various other articles
may be manufactured and in such a manner that the necessary, hollows, recesses,
indents, grooves and the like are formed therein during the operation of rolling and

process
Referring to the accompanying sheets of drawings and to the figures and letters
of reference marked thereon,
Figure 1.is a general elevation of a pair of rolls fitted and geared according to
my invention and driven by steam or other motive power.
Figure 2 is an enlarged view of one roll (say the upper) part partly in section.
Figure 3 is an end view of the same shewing bolts for holding segmental dies in
place.
Figure 4 is an enlarged section through the dies fitted to upper and lower roll
shewing also section of metal blank as it passes between them.
Figure 5 is a diagram on an enlarged scale shewing an upper and lower seginental
die in position and during the rolling of a horse shoe, such dies occupying each a
quadrant of the roll to which it is attached.
In carrying out my invention I provide a pair of rolls such as A and A¹
Figures 1 and 2, A being the upper and A¹ the lower roll-these are mounted in
suitable bearings carried by standards or frame such as B B Figure 1 on a bed or
base C. The ends or shafts of these rolls project as at D D and on them are fixed
toothed wheels gearing into each other in such a manner as to ensure the coincident
working of the rolls and segmental dies attached thereto the lower roll driving the
upper roll and in turn being driven by multiplying gearing actuated by motive
power.
To the circumference of the main rolls attach steel or other dies E E E E by
means of bolts F F F F or in any other desirable manner-these dies are formed in
segments each segment representing the upper or lower section of the blank to be
rolled and the rolls are made of such diameter as to correspond with a certain number
of such segmental dies. The drawings shew the rolls prepared for rolling horse
shoes and to receive four of the segmental dies. E E E E so that four blanks are rolled
at each revolution of the rolls-corresponding dies being attached to the lower roll
and the two being made to work coincidently by means of the gearing before
mentioned. The rolls proper are channelled as shewn to receive the segmental dies
and cored out where necessary for the bolts &c.
Figure 5 shews an enlarged view of the upper and lower dies for rolling the blanks
for horse shoes and in this view E₁ and 2 shew one each of four upper and lower
segmental dies forming the complete circumference of the finished rolls when bolted
in their respective positions after being placed in the turned channels or chases
prepared in the rolls proper for their reception. Any desirable number of channels
or chases and of the requisite width and depth for various shapes and forms of dies
may be formed in the rolls according to the numbers and sizes of the dies to be used
so that a greater or less number of blanks may be rolled out at each revolution of the
rolls.
It will be seen that by my arrangement of loose dies fixed or attached to the outer
circumference of rolls the upper and lower being caused to exactly coincide and the
dies being made in segments to correspond with the circumference of the rolls
proper blanks for various purposes may be continuously rolled from metal bars shaped
to the desired section and having the necessary recesses, grooves &c. formed thereon
during the process of rolling.
Having now particularly described and ascertained the nature of my said inven
tion and in what manner the same is to be performed 1 declare that what I
claim is ;
1. In machinery for rolling blanks. for various purposes such as the manufacture
of horse shoes, fitting or attaching to the circumference of rolls, loose segmental dies
in such a manner that the upper and lower dies attached to the upper and lower rolls
respectively shall exactly coincide so as to correctly shape and indent bars passing
through such rolls and dies and so that little or no part of the bar is wasted,

page_text: the action of the dies and rolls being continuous in the same direction and at the
same speed.
2. Turning or coring channels in rolls for the reception of loose segmental dies
substantially as herein described and illustrated.
3. The method of and apparatus for rolling blanks for various purposes substantially
as herein described and as illustrated by the accompanying drawings.
