IMPROVEMENTS IN THE MANUFACTURE OF SWIVELS, AND SPRING HOOKS
Year: 1884

page_text: I, RICHARD COLLARD of 33, B Regent Place Birmingham, in the County of
Warwick, Stamper, Piercer, and Swivel Maker, do hereby declare the nature of
said invention for "IMPROVEMENTS IN THE MANUFACTURE OF SWIVELS, AND
SPRING HOOKS, to be as follows :-
The Drawing herewith shews a Swivel, or Spring Hook. I will name the parts
of the said Drawing near the letters therewith, thus
a. the Barrel part.
b. the Bow part.
c. the Latch part.
d. the Loop.
The aforesaid parts a. b. c. I name the Body. of the said Swivel, or Spring
Hook.
The only difference between a Swivel, and a Spring Hook, being in the mode of
connecting the Loop d. to the Body, a. b. c. for a Swivel, the Loop d. will be so
connected to the Body, a. b. c. as will allow the Loop, d. to swivel, or rotate, in, or
on, the Body, a. b. a.
For a Spring Hook, the Loop d. will be fixed immovable, to the Body, a. b. c.
and the said Loop. d. will not Swivel, or rotate.
My Invention has reference to the Bodies, of Swivels, and Spring Hooks, and
consists of,
Making the Body, of a Swivel, or Spring Hook, of one piece of thin metal.
And Folding the said thin Metal, to make it strong enough, and big enough, for
the Bow part, and the Latch part, of the said Body, of a Swivel, or Spring Hook,
Dated this third day of March 1884.

Hook.
The only difference between a Swivel, and a Spring Hook, being in the mode of
connecting the Loop, d-to the Body a-b-c.
For a Swivel 'the Loop d. will be so connected to the Body a. b. c. as will allow 2
the Loop d. to Swivel, or rotate, in, or on, the Body a. b. c.
For a Spring Hook, the Loop d. will be fixed immovable, to the Body, a. b. c.
and the said Loop d. will not Swivel, or rotate.
"..
My said Invention has reference to the Bodies, of Swivels, and Spring Hooks,
and consists of, making the Body, of a Swivel, or Spring Hook, of one piece of thin 2
inetal, and folding the said thin metal; to make it strong enough, and big enough,
for the Bow part, and the Latch part, of the said Body, of a Swivel, or Spring
Hook.
I make said Bodies, in the following manner.
I 'take'a piece of thin metal, out of which I cut a Blank, I cut said Blank, by
means of Dies, or Tools that are well known in the Trade as Press Tools, that is,
Tools that are worked in a Press, the lower Tool has a hole through 'it the shape
of the Blank, the upper Tool is the shape of the Blank, and will fit in the hole fof
the lower Tool, so that by placing a piece of -metal on the lower Tool, and causing
the upper Tool to descend, a Blank is cut, as shewn Figure 2. the said Blank, is to
form tile Body, 'of a Swivel, or Spring Hook.
I then place said Blank, on a Die, said Die having the shape on its face, as
desired on the Blank, and strike it with an upper Die 'that fits the lower Die, this
forms a ridge across the outside of the widest part of the Barrel part, and causes
the Barrel part to project a little distance outwards beyond the level of the
Bow part, it also forms a small conical shaped outward projection near the end of
the Latch part, and mid way from either side, this conical projection is the same
height above the level of the Bow part, as the ridge on the Barrel part is-Shewn
Figure 3.
I then place said Blank on a Die, or drawing through Tool, said Die, or drawing
through Tool having a hole through it, of the desired form, and by the descent of
an upper Tool, the Blank is forced through the Die, or drawing through Tool, and
thus bent throughout its entire length into the form of the Letter U. the wide end
or ridge of the Barrel part forming a much larger U. than the Bow and Latch
parts Shewn Figure 4.

page_text: I then place the Barrel part of said Blank lengthwise between closing Tools,
each Tool having an impression similar to half the Barrel part of the finished
Swivel, and by the descent of the upper Tool, the lateral edges of said Barrel part
are closed together, as shewn Figure 5.
I then place the Bow part of said Blank lengthwise between closing Tools, each
Tool having a groove across its face, and by the descent of the upper Tool the lateral
edges of said Bow part are closed together, and the Bow part thus formed cylindrical,
as shown Figure 6.
I then place the Bow part of said Blank lengthwise between Dies, one or both of
the Dies having a groove across the face, and by striking it with the upper Dic, I
compress the metal, and cause the Bow part to resemble Wire which may be either
half round, Square, or other shape as desired, it is shewn half round, Figure 7.
I then place the Latch part of said Blank, lengthwise on a Die, and by the
descent of an upper corresponding Die, press the metal together, to form the Bit,
that will when the Swivel, or Spring Hook, is finished, act on the Spring the Bit,
is shewn closed Figure 8.
.
I then saw the gap in the Barrel part, and bend the Bow part untill the Latch
Bit enters that gap as shewn Figure 9.
I have now produced a rough Body, for a Swivel, or Spring Hook, though in
working my said Invention I cannot strictly confine myself to the exact number
of processes, as I must be guided by the nature of the metal I am using, some gold,
and other metals, being very hard.
It will be readily understood by any person having the slightest knowledge of
the Trade, that each Drawing of the Blank, shews the form of the Die, in which
the Blank has been struck.
So I now proceed to work in the usual manner, that is I Drill, Turn, add the
Loop d. saw through the Bow at the Latch part, Spring, and Finish in the ordinary
manner, as shewn Figure 1.
°
I am well aware that the Body of a Swivel, is now, and has been for years past,
made of one piece of thick metal, said metal being sufficiently strong to allow the
Bow part, and Latch, to be formed, without folding or doubling the metal, of said
Bow and Latch.
I am also aware that the Barrel part, of the Body of a Swivel, is made of thin
metal, and the Bow and Latch of said Body is made of thick metal, or Wire, for
Plated Swivels the Wire of the Bow being hollow, and so drawn as to show the
Gold on the surface, the back or base metal being turned inside, the said Bow and
Barrel are then connected by soldering.
I am also aware that Swivel Bodies, are cast in one piece.
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
Folding the Metal of the Bow part, and the Latch part, of the Body of a Swivel,
or Spring Hook, substantially as described.
