-I, GEORGE HATTON, of Saltwells House, Brierley Hill, in the County of Stafford,
Iron and Steel Manufacturer, do hereby declare the nature of this invention to
be as follows:-
This invention has reference to the stay bars or studs of chain cables.
Heretofore the said stay bars or studs have usually been made as iron castings but
when so made they are liable to be broken by a sudden blow and when so broken
the stud will come out of the link thereby considerably diminishing the strength
of the cable. This invention consists in making the said stay bars or studs as
wrought steel stampings or wrought iron stampings as herein described thereby
rendering the said stay bars or studs unbreakable and ensuring uniformity of
strength and proper fitting in the links of the cable. Each of the said stay bars
or studs bears the maker's name on one side and the year of manufacture on the
other in raised letters and these letters and figures I am by my method of manu-
facture enabled to stamp in relief on the stay bar or stud.
In stamping the said stay bars or studs from a steel or wrought iron bar I
employ a pair of top and bottom dies each sunk to the shape of one half of the stay
bar or stud as if the same were divided longitudinally crosswise of the links and
these dies are or may be sunk so as to leave a small projecting rib along both sides
of the stay bar or stud where the said name and date are to be. After the web or
fin has been clipped off the stamping the latter is stamped or pressed between
another finishing pair of top and bottom dies each of which is sunk to the shape
of about one half of the said bar or stud as if the same were divided longitudinally
in the plane of the link. One of these finishing dies has or may have the figures
corresponding with the year of manufacture sunk in it and the other die has or may
have the maker's name sunk in it so that when these dies close on to the said
heated bar or stud the aforesaid longitudinal ribs will be forced into the sunk
letters of the dies which will then stand up in relief of the finished stay bar or
stud.
I may so arrange these name dies or finishing dies that I insert or lay two rounded
bolts or bars or filling up pieces in the bottom die shaped so as to bear against the
concaved or hollow ends of the stay bar or stud so as to support the same whilst
being stamped in the dies to impress the name and date or otherwise finish them
as stated above.

to be employed in the said Manufacture.
I, GEORGE HATTON, of Saltwells House, Brierley Hill, in the County of Stafford,
Iron and Steel Manufacturer, do hereby declare the nature of this invention and
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:―
This invention has reference to the stay bars or studs of chain cables. Here-
tofore the said stay bars or studs have usually been made as iron castings but
when so made they are liable to be broken by a sudden blow and when broken
the stud will come out of the link thereby considerably diminishing the strength
of the cable.
This invention consists in making in the manner hereinafter described, the stay
bars or studs as wrought iron or wrought steel stampings thereby rendering the
stay bars or studs unbreakable and ensuring uniformity of strength and proper
fitting in the links of the cable. Each of the said stay bars or studs bears the
maker's name on one side and the year of manufacture on the other in raised letters
and these letters and figures I am by my method of manufacture enabled to
stamp in.relief on the stay bar or stud.
I will describe my invention by referring to the accompanying drawings on
which Fig. 1 is a front elevation Fig. 2 is a plan and Fig. 3 is an end elevation of
a chain cable stay bar or stud made in accordance with this invention Fig. 4 is
a cross section of the same on line X X of Fig. 1; Fig. 5 is a front elevation and
Fig. 6 is a plan and Fig. 7 is an end view of the partly finished stay bar or stud
as it leaves the first pair of dies; Fig. 8 is a sectional front elevation and Fig. 9
is a cross sectional elevation of the first pair of dies which I use in forming the
stamping shewn by Figs. 5, 6 and 7 and Fig. 10 is a plan of the bottom die shewn
in Figs. 8 and 9; Fig. 11 is a sectional elevation of one form of finishing dies
which I employ for finishing the said stay bars or studs; Fig. 12 is a plan of the
bottom die shewn by Fig. Il; Fig. 13 is an end elevation of the dies shewn in
Fig. 11; Fig. 14 is a front sectional elevation of another form of my said finish-
ing dies and Fig. 15 is a plan of the bottom die shewn in Fig. 14; Fig. 16 is a
sectional front elevation of a modification of the said finishing dies; Fig. 17 is a
plan of the bottom die shewn in Fig. 16, and Fig. 18 is a cross sectional elevation
of the dies shewn by Fig. 16; Fig. 19 is a front sectional elevation of a further
modification of the said finishing dies and Fig. 20 is a plan of the bottom die
shewn in Fig. 19; Fig. 21 is a sectional front elevation of a further modification of
the said finishing dies and Fig. 22 is a plan of the bottom die shewn in Fig. 21.
The same letters of reference indicate the same or corresponding parts in all the
figures.
In stamping in accordance with this invention a stay bar or stud A of the well
known shape illustrated by Figs 1, 2, 3 and 4, a steel or wrought iron bar of the
proper size is first heated and stamped to the shape shewn by Figs. 5, 6 and 7 by
a pair of top and bottom dies B C (see Figs. 8, 9 and 10) each of which is sunk
at bc to the shape of one half of the stay or stud as if the same were divided
longitudinally crosswise of the link that is in the plane Y Y of Figs. 1, 3 and 4
but these dies have no sinkings for the letters or figures on the stay bar or stud.
The ends 5 of the sinking 6' and the ends of the sinking care convex to
correspond with the concave ends a² a³ of the stud A. It will be seen by Figs. 5,
6 and 7 that the stamping A as it leaves these dies is of about the same shape and
size as the finished stay bar or stud but that it has no figures or letters on it. After

page_text: the web or fin a¹ of this stamping has been clipped off the stamping is heated and
stamped or pressed at right angles to its original position between a finishing
pair of top and bottom dies such as those marked D and E Figs. 11, 12 and 13 each
of which is sunk to the shape of about one half of the finished stay bar or stud A
(Figs. 1, 2, 3 and 4) as if the same were divided longitudinally in the plane of the
link that is in the plane Z Z of Figs. 2, 3 and 4. It will be seen that the die E
has a sinking e corresponding with one half of the stud A and the other die D
has a sinking a corresponding with the other half of the stay bar or stud the
meeting faces of the dies corresponding with the plane Z Z in Figs. 2, 3, 4, 6 and 7.
Owing to the concaved shape of the ends a³ a³ of the stay bar or stud A the sink-
ings ed of the dies shewn by Figs. 11, 12 and 13 are at an angle to the horizontal
so that the top die D will strike the stud properly when falling and will clear
the stud when the die is being lifted again. It will be seen that the upper die D
has a convex projecting part d³ corresponding with the concave end a³ of the stud
and the bottom die E is at et shaped to correspond and also has a convex projecting
parte at the termination of the sinking e¹ corresponding with the other concaved
end 3 of the stud so that when the two dies D are placed together the space
between will correspond exactly with the finished stud. One of these finishing
dies say the bottom die marked E has or may have figures such for instance as 1898
or other figures corresponding with the year of manufacture sunk in it at and
the other die D has or may have the maker's name or initials or mark sunk in it
at so that when these dies D E close on to the beated stay bar or stud the sunk
letters or figures of the dies will be impressed at a as on the stay bar or stud A
and stand up in relief on the same as shewn in Figs. 1, 2, 3 and 4 and at the same
time the concave ends of the stay bar or stud will be pressed by the convex parts d³ es
of the dies to remove any roughness left by the removal of the fin a¹ and the stay
bar or stud will then be finished.
Instead of the finishing dies D E being made as above described and shewn by
Figs. 11, 12 and 13, the sinkings d' e' may be horizontal and in this case I insert
or lay two rounded bars or filling up pieces in the bottom die shaped so as to bear
against the concaved or hollow ends of the stay bar or stud so as to support the
stay bar or stud whilst being stamped in the finishing dies to impress the name
and date and finish the studs as stated above.
These two rounded bars or filling up pieces may be constructed and arranged
and combined with the bottom finishing die E in various ways as will be readily
understood so that one or both of these filling up pieces can readily be removed from
the die to permit of the insertion of the stay bar or stud in the
bottom die and the removal of the finished stay bar or stud therefrom. For instance
as shewn by Figs. 14 and 15 the two filling up pieces marked respectively F¹ Fª
consist of bars rounded at f' to the proper convex shape to bear against the con-
caved ends a² a³ of the stay bar or stud A and made to slide endwise in correspond-
ing cross grooves e e formed in the bottom die E which thus secure these bars or
filling up pieces F1 F2 in position. After the stay bar or stud has been stamped
and finished in the dies and E as aforesaid the filling up piece F3 has to be
removed out of the die so as to permit of the removal of the finished stay bar or
stud. After another stay bar or stud blank A in the form shewn in Figs. 5, 6
and 7 (but with the web or fin clipped off) has been placed in position in the
bottom die E the filling up piece F2 is slided endwise into the position shewn in
Figs. 14 and 15 to support the concaved ends of the stay bar or stud A while the
finishing dies act upon it. For convenience of handling the rounded bars or
filling up pieces F1 F2 they may as shewn for instance by Fig. 15 be both con-
nected on to one handle bar 13 as by the links h and joint pins i.
Figs. 16, 17 and 18 shew the finishing dies D E provided with another arrange-
ment of filling up pieces F1 F2 which in this case are made of a complete circular
form in cross section corresponding with the concave ends a² a3 of the stay bar
or stud and the grooves e6e7 in the bottom die E are made of a corresponding form
to receive the bars or filling up pieces F1 F*

page_text: Figs. 19 and 20 shew the finishing dies D E provided with another arrange-
ment of the filling up pieces F1 F2 which in this case are made of a flattened oblong
shape in cross section with rounded faces f¹ f' to correspond with the concave
ends a² a³ of the studs and so fitted in the grooves e6e7 of the bottom die E. as
to lift up as represented by the dotted lines in Fig. 14 for the removal of the
finished stud. G¹ G² are the upper ends of two push rods located in the bottom
die E for the purpose of raising the filling up pieces F1 F3 as aforesaid. Instead
of both of the filling up pieces F Fa being made to turn upwardly as shewn in
Fig. 19 it will be evident that one of the filling up pieces F F may be stationary.
It will be evident that many other ways of arranging the filling up pieces F1 F2
so that one or both of them can be readily removed for the insertion of the stamp-
ing and removal of the same may be employed without departing from the nature
of my invention, for instance as shewn by Figs. 21 and 22 where the filling up
pieces are made in the form of blocks which fit in vertical recesses es e in
the die E and are adapted to be lifted up by the push rods G¹ G2 in the bottom die E
for the removal of the finished stamping and to be knocked down again with
another stamping between them to be finished by the dies.
When the letters figures or other distinguishing marks which are impressed on
the stay bar or stud by the finishing dies are required to be recessed in the stay
bar or stud instead of standing up in relief, then the said letters or figures or other
distinguishing marks have to be cut to stand up in relief in the finishing dies as
will be readily understood.
The first pair of dies B C may if desired be sunk at each side as at 6² 63 c² c³ as
shewn by the dotted lines in Figs. 8, 9 and 10 so as to form a projecting rib a
along both sides of the stay bar or stud A as shewn by dotted lines in Figs. 5, 6
and 7 where the name and date or other mark in relief are to be so that when the
stay bar or stud is stamped in the finishing dies as aforesaid this rib a will the better
help to fill up the letters or figures which are sunk in the finishing dies D E.
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:
1. In the manufacture of chain cables making the stay bars or studs as steel
or iron stampings by first stamping them in a pair of dies sunk to correspond with
the stay bar or stud if divided in a plane at right angles to the plane of the link
and then finishing this stamping in a pair of dies sunk to correspond with the stay
bar or stud if divided in a plane parallel with the plane of the link these last
named dies being also sunk with figures words or marks which are impressed on
the finished stay bar or stud, substantially as herein before described.
2. In the manufacture of chain cables making the stay bars or studs as steel
or iron stampings by first stamping them in a pair of dies sunk to correspond with
the stay bar or stud if divided in a plane at right angles to the plane of the link
and also sunk as at b² to form projecting ribs as 6 on the stay bar or stud where
the figures words or marks are to be and then finishing this stamping in a pair of
dies sunk to correspond with the stay bar or stud if divided in a plane parallel
with the plane of the link these last named dies being also sunk with figures words
or marks which stand up in relief on the finished stay bar or stud substantially
as herein before described.
3. The improved finishing dies for stamping the stay bars or studs of chain
cables, sunk to correspond with the finished stay bar or stud and form the letters
or figures on the same and provided with removable convex filling up pieces such
as F F adapted to fit against the concaved ends of the stay bar or stud to support
the same whilst they are being stamped and to allow of the insertion of the stay
bar or stud in the finishing die and the removal of the finished stay: bar or stud
therefrom, substantially as described.
4. The improved finishing dies D E for stamping the stay bars or studs of
chain cables sunk in an inclined direction to correspond with the finished stay bars

page_text: or studs and form the letters or figures on the same one of the dies having a convex
projection to correspond with one of the concaved ends of the stay bar or stud
and the other die having a convex projection e³ to correspond with the other concave
end of the stay bar or stud all substantially as herein before described and shewn
by Figs. 11, 12 and 13 of the accompanying drawings.
