Improvements in and Tools for the Manufacture of Axle Clips..
I ARTHUR. OLDBURY of Reliance Works Wednesbury in the County of
Stafford, Manager of Works do hereby declare the nature of this invention to
be as follows
Axle clips are used for connecting carriage springs to their axles, each axle clip
consisting of a strong plate, of wrought iron having at its middle a double rect-
angular bend or loop or seat, open at top, for clipping or embracing three sides of
the axle, the horizontal flaps or parts on either side the middle or seat part being
formed for producing what are technically called caulked axle clips, or for
producing butterfly clips or for producing clips having flat flaps and provided
with holes called plain clips and other analogous axle clips.
My invention consists in manufacturing axle clips of the kinds referred to by a
stamping process conducted in the manner and by the use of the tools hereinafter
described.
:
The principal pair of tools which I use have their acting faces so shaped that
when brought together they enclose a space having nearly the figure of the axle
clip to be made. That is to say, the said tools fashion the middle of the heated
piece of iron operated upon into a seat or open loop part having a slightly arched
bottom and sides outwardly inclined and slightly bend downwards the end parts of
the heated piece from which the flaps, on either side of the seat part, are to be
made. The figure thus given to the partly made clip enables it readily to leave
the tools.
'
The lower tool of the pair of tools described is fixed upon the bed of a stamp,
steam hammer, or other percussive apparatus and the upper tool is fixed to the bolt.
or movable part of the stamp, steam hammer or percussive apparatus. The piece
of wrought iron from which the axle clip is to be made having been heated to a
red heat is placed in the lower tool and the upper tool being brought down upon
it, say four or five times, a partly made axle clip of the kind herein before described
is produced..
When the bottom of the seat or middle part of the clip is required to be furnished
with a peg for preventing the slipping of the clip on the axle, the said peg is made
by the stamping process,
the two tools having the required conformation for forming
the peg.
After the partly made axle clip has been fashioned by stamping in the manner
described it transferred to a pair of stripping or clipping tools by which the fins
or parts pressed out at the junction of the shaping tools are removed the said
stripping tools having the same configuration as the shaping tools. The stripped
partly made axle clip is finally transferred to a bottom plain die or support and by
the descent of a flat tool striking the arched bottom of the middle seat or loop
part the said arched bottom is flattened, the inclined,sides of the sent or loop
brought parallel and the flap parts on either side the seat brought into a horizontal
position.
The axle clip thus made is finished in the ordinary way.

Improvements in and Tools for the Manufacture of Axle Clips.
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 ascer-
tained in and by the following statement:-
+
Axle clips are used for connecting carriage springs to their axles, each axle clip
consisting of a strong plate of wrought iron having at its middle a double rect-
angular bend or loop or seat, open at top, for clipping or embracing three sides
of the axle, the horizontal flaps or parts on either side the middle or seat part
being formed for producing what are technically called caulked axle clips, or
for producing butterfly clips or for producing clips having flat flaps and provided
with holes called plain clips and other analogous axle clips.
My invention consists in manufacturing axle clips of the kinds referred to by a
stamping process conducted in the manner and by the use of the tools hereinafter
described.
The principal pair of tools which I use have their acting faces so shaped that
when brought together they enclose a space having nearly the figure of the axle
clip to be made. That is to say, the said tools fashion the middle of the heated
piece of iron operated upon into a seat. or open loop part having a slightly
arched bottom and sides outwardly inclined and slightly bend downwards the end
parts of the heated piece from which the flaps on either side of the seat part are
to be made. The figure thus given to the partly made clip enables it readily to
leave the tools.
"
The lower tool of the pair of tools described is fixed upon the bed of a stamp
steam hammer or other percussive apparatus and the upper tool is fixed to the
bolt or movable part of the stamp, steam hammer or percussive apparatus. The
piece of wrought iron from which the axle clip is to be made liaving been heated
to a white heat is placed in the lower tool and the upper tool being brought
down upon it, say, four or five times, a partly made axle clip of the kind herein-
before described is produced.
When the bottom of the seat or middle part of the clip is required to be
furnished with a peg for preventing the slipping of the clip on the axle, the said
peg is made by the stamping process, the bottom tool having the required con-
formation for forming the peg:
After the partly made axle clip has been fashioned by stamping in the manner
described it is transferred to a pair of stripping or clipping tools by which the
fins or parts pressed out at the junction of the shaping tools are removed the
said stripping tools having the same general configuration as the shaping tools.
The stripped partly made axle clip is finally transferred to a bottom plain dic or
support and by the descent of a flat tool striking the arched bottom of the middle
seat or loop part the said arched bottom is flattened, the inclined sides of the seat
or loop brought parallel and the flap parts on either side the seat brought into a
horizontal position.
The axle clip thus made is complete.
Figure 1 of the accompanying drawings represents in side elevation and Figure
in plan, of underside, the upper shaping tool and Figure 3 represents in side
elevation, and Figure 4 .in plan, of underside, the lower shaping tool of the pair of
tools which 1. employ in the manufacture according to my invention of caulked axle
clips Figure 5 represents in section the two tools brought together with a parily
made axle clip shaped between them; Figure 6 represents in side elevation and
plan the partly made caulked axle clip, made in the tools, Figure 5 detached.
;
The partly made clip Figure 6 consists of the seat or open loop part a, having a

page_text: peg on the upperside of its bottom, and flaps a², a² on either side of the seat
part a. It will be seen that the bottom of the seat a is slightly arched and the
sides of the seat are inclined and the flap parts are slightly curved.
The upper shaping tool is marked e and is fixed to the bolt of the stamp or head
of the steam hammer and the bottom shaping tool is marked d and is fixed to the
bed of the stamp or steam hammer. The parts of the two tools which fashion the
seat or open loop part of the clip are marked e and f, and the parts of the two tools
which fashion the flaps of the clip are marked g, g and h, h. The ends of the
hollow parts in the upper tool which fashion the flaps, have cross recesses at i, i in
which the cross bars at the ends of the flaps of the clip are formed. The middle
of the part of the lower tocl has in it a hole or recess k in which the peg b on the
bottom of the seat is formed. It will be seen by reference to Figure 5 that when
the two dies c, d are brought together their acting faces enclose a space having the
figure of the partly made axle clip Figure 6.
The piece of wrought iron from which the axle clip is to be made having been
heated to a white heat is placed on the lower tool d and the upper tool e is brought
down upon it several times. The said piece of heated wrought iron is thereby
fashioned into an axle clip having the configuration represented in Figure 6 and
in the tools Figure 5. The clip so made has fins attached to its edges marked in
Figure 6 which fins have been formed by the heated metal during the shaping
operation being pressed out at the junction of the tools.
The configuration represented in Figure 6 given to the partly made clip by the
stamping tools enables it to readily leave the said tools.
Figure 7 represents in elevation the upper stripping tool and Figure 8 in
elevation and plan of upperside, the lower stripping tool which I use for removing
the fins from the edges of the partly made clip, and Figure 9 represents the
two tools after the upper tool has entered the lower tool and the clip has been
forced through the said lower tool and stripped of its fins by the cutting edges
of the stripping tools so as to produce the partly made clip represented in
Figure 10. It will be seen that the stripping tools have the same general con-
figuration as the shaping tools, cutting edges in the stripping tools replacing the
acting faces in the shaping tools.
The clip Figure 10 is finished by giving it the shape represented in Figure 11.
To effect this the clip Figure 10 is placed in a plain die or support and a flat tool
is made to descend upon the arched bottom of the clip. The said arched bottom is
thereby flattened and the inclined sides of the seat brought parallel as well as the
flaps flattened or brought horizontal as represented in Figure 11.
I make butterfly axle clips and plain axle clips and other analogous axle clips
substantially in the manner herein before described and represented with respect to
the manufacture of a caulked axle clip such changes only in the shape of the tools
being made as will fit them to produce the kind of axle clip required. That is to
say, in forming butterfly axle clips the parts of the shaping tools in which the flaps
are fashioned have the configuration necessary to produce the butterfly ends of the
flaps and in forming plain clips the recesses in the top shaping tool are
omitted and holes are formed in the plain flaps by the stamping operation.
Having now particularly described and ascertained the nature of my inven-
tion and the manner of performing the same I declare that I claim as my
invention:
Manufacturing axle clips by stamping and shaping processes conducted in the
manner and by the use of the tols and appliances herein before described and
illustrated in the accompanying drawings; that is to say, first stamping the heated
wrought iron by the use of the pair of shaping tools represented in Figures 1, 2, 3,
4 and 5 so as to produce a partly made axle clip of the kind represented in Figure 6,
or other analogous axle clip; next stripping the fins from the partly made axle
clip by the use of the pair of stripping tools represented in Figures 7, 8 and 9 and

page_text: finally converting the partly made axle clip Figure 10 into a clip of the kind
represented in Figure 11 or other analogous axle clip substantially as described
and illustrated.
