Improvements in the Manufacture of Clips for the Springs of Carriages
and in Tools to be Used in the said Manufacture.
I, ARTHUR ÜLDBURY, of Reliance Works, Wednesbury, in the County of
Stafford, Manager of Works, do hereby declare the nature of this invention
to be as follows:-
My invention consists of the improvements hereinafter described in the
manufacture of clips for the springs of carriages and in the tools used in the
said manufacture by which improvements the said manufacture is simplified
and time and labour saved.
In order that my invention may be the better understood I will briefly
describe the ordinary manufacture of a clip for the spring of a wheel carriage.
A straight cylindrical bar of iron is shaped or fashioned between a pair of
dies in a press so as to give to the said bar at different parts the sectional figure
required in the finished clip. The said fashioned straight bar is atterwards bent
by means of other tools into the inverted U or forked shape of a carriage spring
clip; that is to say, the two end parts are bent near the middle at right angles"
to the middle part the said end parts being brought parallel to each other.
In making a clip according to my invention I take a cylindrical bar of iron
of a length somewhat greater than that required to form the clip to be made.
1 roughly bend the bar into a figure somewhat resembling the letter J the long
arm or branch constituting a handle by which the bar is manipulated in the
subsequent treatment of the said bar. I heat the bent bar to redness and operate
upon it by means of a pair of dies or tools in a stamp so as to give to the said
bar at different parts the sectional figure desired. The tools which constitute
part of my invention consist of a pair of dies each die having a recess the
counterpart of one half of the clip to be made. The top die has a shank by
which it is attached to the hammer of the stamp. The bottom die is fixed on
the bed of the stamp. The closed dies have a figure in plan somewhat resembling
an inverted letter U.
The clip thus partially made is finished by removing the burrs or 'fins' pro-
duced and the long arm or handle in a pair of stripping tools worked in a press.
The lower stripping tool of the pair is hollow the passage through it corre-
sponding exactly to the size and shape of the clip to be made.
The upper tool of the pair of stripping tools has a shape proper to pass into
the recess in the lower tool and is provided with a screwed shank by which it
is fixed to the plunger of the press. The partially made clip is placed over
the hole in the lower stripping tool and the upper tool descending forces the
clip through the hole in the lower die leaving the burr or fin and projecting
ends removed from the stamped clip on the face of the lower stripping tool.

I, ARTHUR OLDBURY, of Reliance Works, Wednesbury, in the County of
Stafford, Manager of Works, do hereby declare the nature of my invention and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
-
My invention consists of the improvements hereinafter described in the
manufacture of clips for the springs of carriages and in the tools used in the
said manufacture by which improvements the said manufacture is simplified
and time and labour saved.
In order that my invention may be the better understood I will briefly
describe the ordinary manufacture of a clip for the spring of a wheel carriage.
A straight cylindrical bar of iron is shaped or fashioned between a pair of
dies in a press so as to give to the said bar at different parts the sectional figure
required in the finished clip. The said fashioned straight bar is afterwards bent
by means of other tools into the inverted U or forked shape of a carriage spring
cip; that is to say, the two end parts are bent near the middle at right angles
to the middle part, the said end parts being brought parallel to each other.*
In making a clip according to my invention I take a cylindrical bar of iron
of a length somewhat greater than that required to form the clip to be made.
1 roughly bend the bar into a figure somewhat resembling the letter J the long
arm or branch constituting a handle by which the bar is manipulated in the
subsequent treatment of the said bar. 1 heat the bent bar to redness and operate
upon it by means of a pair of dies or tools in a stamp so as to give to the said
bar at different parts the sectional figure desired. The tools, which constitute
part of my invention, consist of a pair of dies each die having a recess the
counterpart of one half of the clip to be made. The top die has a shank by
which it is attached to the hammer of the stamp. The bottom die is fixed on
the bed of the stamp. The closed dies have a recess of a figure in plan some-
what resembling an inverted letter U.
The clip thus partially made is finished by removing the burrs or fins pro-
duced and the long arm or handle in a pair of stripping tools worked in a stamp.
The lower stripping tool of the pair is hollow the passage through it corre-
sponding exactly to the size and shape of the clip to be made.
The upper tool of the pair of stripping tools has a shape proper to pass into
the recess in the lower tool and is provided with a screwed shank by which it
is fixed to the plunger of the stamp. The partially made clip is placed over
the hole in the lower stripping tool and the upper tool descending forces the
clip through the hole in the lower die leaving the burr or fin and projecting
ends removed from the stamped clip on the face of the lower stripping tool.
Figure 1 of the accompanying drawings represents in plan the roughly bent
cylindrical bar from which a carriage spring clip is made according to my
invention.
Figure 2 represents in plan the said bent bar after the stamping operation
by which the bent portion of the said bar is fashioned into the figure of a
carriage spring clip.
Figure 3 represents the partly made clip after treatment of the stamped bar
in the stripping tools hereinafter described by which the burr and handle part
of the bar are removed.
Figure 4 represents the finished clin

page_text: Figure represents in side elevation and Figure 6 partly in front elevation
and partly in vertical section the pair of stamping tools which I use in carrying
my invention into effect.
Figure 7 represents in plan the bottom die or tool.
Figure 8 represents in vertical section a pair of stripping tools constructed
according to my invention.
The same letters of reference indicate the same parts in the several figures
of the drawings.
In making a carriage spring clip according to my invention, I bend a
cylindrical bar of iron into the form represented in Figure 1. I place the bent
end a after it has been heated to redness on the lower die 6 (see Figure 7)
fixed on the bed of a stamp. The acting faces of the pair of dies b and c are
exactly similar that is to say they have a recess the counterpart of one half of
the clip to be made, one of the two parallel branches of the recess passing out
at the front of the die so as to accommodate part of the long arm or handle a²
(see Figure 2) of the bent bar by which the clip in course of manufacture is
handled and manipulated.
On the descent of the upper die c, which is carried by the plunger of the
stamp, the bent part a of the bar is fashioned into the form represented in
Figure 2. The sectional figure at one part of the partly made clip is represented
in the section of the tools in Figure 6.
The next process in the manufacture of the clip is the removal of the burr
or fin a produced in the stamping operation and also the removal of the long
arm or handle a2 by which the heated bent bar has been manipulated in the
stamping process and this is effected by the use of a pair of tools of the kind
represented in vertical section in Figure 8.
The lower tool d has a slot. or hole passing through it from top to bottom
of a size and shape proper to permit a finished clip to be passed therethrough
and the acting part of the upper tool has a shape proper to pass into the slot
or hole in the lower tool. The slot or. hole in the lower tool d and the acting
part of the upper tool e have a figure in plan the same as that of the partly
made clip Figure 3. The stamped bar Figure 2 is placed over the hole in the
tool d as is represented in Figure 8, and the upper tool e which is carried by
the plunger of a stamp in its descent forces the part having the shape of the
clip through the slot or hole in the lower tool d, the fin a¹ and handle part a²
of the bar being left on the face of the lower tool.
The stripped clip has now the form represented in Figure 3.
The cylindrical ends of the partly made clip are screwed in the ordinary way
as is represented in the finished clip Figure 4.
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:-
First The improvements in the manufacture of clips for the springs of car-
riages herein before described and illustrated in the accompanying drawings,
the said improvements consisting essentially in taking a long cylindrical bar of
iron and bending one end as is represented in Figure 1, operating on the bent
end of the said bar in the tools of a stamp so as to fashion the bent end into
the figure of the clip to be made and subsequently operating on the stamped
bar in a pair of stripping tools so as to remove the burr or fin and part of the
bar unoperated upon by the dies of the stamp the cylindrical ends of the clip
thus made being screwed as is usual substantially as hereinbefore described
and illustrated.
Secondly; The improved tools herein before described and illustrated in the
accompanying drawings to be used in the manufacture of clips for the springs
of carriages by the process or processes claimed in the prior claim, the said.
tools consisting of a pair of stamping dies of the particular construction herein-
