i, EBENEZER PARTRIDGE of Litho Villa, Poplar Avenue, Edgbaston, near
Birmingham, Warwickshire, Founder and Manufacturer do hereby declare the
nature of this invention to be as follows:-
6
The object of this invention is, to make clips for axles from cold metal by first
gripping the bar between two shaped plates and then by a shaped head or force" to
force the two plates into a hollow bed by two compressions, the first of which turns
the two ends of the bar up and causes the gripped part to enter the bed-die, the
second pressure taking the two plates and bent portion down to the bottom of the
bed-die leaving the loop of the flap of perfect shape and the corners properly rounded,
the inner corners being square to fit the axle.
This process or operation prevents crystalization or injury to the fibres of the metal
and leaves both sides of the metal perfectly smooth with clean edges which obviates
filing, grinding, or dressing up as is usual with axle clips at present constructed.
The bent clip thus. prepared is then placed into another but divided bed-die of
corresponding shape, this being in two parts and capable of being drawn towards
each other by bolts. A tongue or block which fits the hollow of the clip is inserted
into it and the two parts of the bed-die are screwed up to fix the sides of the clip and
the tongue rigidly.
A V or inclined faced piece of metal (steel) is then laid in between the two
upstanding ends of the clip and the press head or "force" is brought down to open
out the two ends and as soon as the V or inclined piece touches the tongue, it is

page_text: removed and the press head or
"force
continues its motion to lay the two ends
down, perfectly flat and true, upon the bed-die.
On the press head being raised the tightening serews of the bed-die are loosened
and the tongue, and the made flap are lifted out, the flap being ready for holes to be
punched, if holes are required, otherwise the flap is ready for use.
This mode of manufacture is applicable for all kinds of clips, whether of the
ordinary, or old fashioned plain, or caulk clip, or the butterfly, or winged clip, or
affixable solid clips, or what are termed affixable solid flaps, such as those patented
by me on the 9th day of November in the year 1886 in or to which a top plate is
arranged to be screwed or rivetted to the clip or flap to fix it to the axle.

A Novel Method of Making Clips for Axles and in Tools or Dies
for the Purpose.
I EBENEZER PARTRIDGE of Litho Villa, Poplar Avenue, Edgbaston, Birmingham,
Warwickshire, Founder and Manufacturer do hereby declare the nature of my said
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 this invention is, to make clips for axles from cold metal by first
gripping the bar between two shaped plates and then by a shaped head or "force
to force the two plates into a hollow bed by two compressions the first of which
turns the two ends of the bar up and causes the gripped part to enter the bod-die, the
second pressure taking the two plates and bent portion down to the bottom of the
bed-lie leaving the loop of the flap of perfect shape and the corners properly rounded
the inner corners being square to fit the axle.
This process or operation prevents crystalization or injury to the fibres of the
metal and leaves both sides of the metal perfectly smooth with clean edges which
obviates filing, grinding or dressing up as is usual with axle clips at prosent
constructed.
The bent clip thus prepared is then placed into another but divided bed-die of
corresponding shape in its hollow, this being in two parts and capable of being
drawn towards each other by bolts.
A tongue or block which fits the hollow of the clip is inserted into it and the two
parts of the bed-die are screwed up to fix the sides of the clip and the tongue rigidly.
A V or inclined faced piece of metal (steel) is then laid in between the upstanding
ends of the clip and the press head or "force," is brought down to open out the two
ends and as soon as the V or inclined piece touches the tongue it is removed and the
press head or force continues its motion to lay the two ends down perfectly flat and
true upon the bed-die.
On the press head being raised the tightening screws of the bed-die are loosened
and the tongue and the made flap are lifted out, the flap being ready for holes to be
punched, if holes are required, otherwise the flap is ready for use.
This mode of manufacture is applicable for all kinds of clips whether of the ordinary
or old fashioned plain or caulk clip or the butterfly or for winged clips or affixable
solid clips or what are termed affixable solid flaps such as those patented by me on
the 9th day of November 1886 in or to which a top plate is arranged to be screwed
or rivetted to the clip or flap to fix it to the axle.
According to my invention which is clearly shown in the annexed drawings I take
a strip of bar iron A of the required length and place it between a bed piece or die B
such as I show at Figure 1, said die B being first fixed in the jaws of a vice Û for
convenience or it may be in any other support and I cause a top die D to come into
close contact by turning the nuts E of screw bolts which forces the centre part of the

page_text: strip A to take the shape of the die the pressure causing the ends to cockle up to the
position shown by dotted lines marked F, F. The two ends F, F, are then hammered
down to the position indicated by dotted lines G, G, and the appliances are removed
from the vice C, C, the two end pieces G. G, are then hammered into close contact
with the side walls of the bottom die B which gives the metal a or channel iron
shape in cross section. The strip of motal thus far shaped is removed from between
the dies B, D, and placed between two other die plates H, H, (Figure 2) with their
ends standing up as at I, I, Figure 2, the bottom of the channel resting upon a
strip J. A piece of steel K is then inserted into the hollow of the strip A and the
whole of these appliances are placed upon a flat bed or table a wedge is introduced
between the two standing up ends 1, 1, until they assume a position shown by dotted
lines L L and the ends of the strip are hammered or are forced by a press head on
to the dies H, H, as indicated by the full lines in Figure 2.
I prefer to make a number of these clips at the same operation and for convenience
I make the dies B, D, of such a length that four strips of metal A can be placed
between them the dies H, H, also corresponding as shown by the plan view of the
dies H, H, Figure 3.
The pressure exerted for the second pressing somewhat fixes the channel portion of
the clip A between the two dies or cheeks H, H, and to remove the clip the nuts and
bolts M, M, are loosened and the piece of stoel K removed.
The clip thus made is ready for attachment to an ordinary axle as a plain clip
or flap.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
The particular method of manufacturing clips for axles also the tools used for the
purpose as described with reference to Figures 1, 2, and 3 of the drawings annexed.
