PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Lasso and other Rings,
Buckles, and certain other Metal Harness Fittings.
We, MATTHEW HARVEY, ALFRED HARVEY and FRANK HARVEY, trading
together as Matthew Harvey & Co., of Glebeland Works, Walsall, Staffordshire,
General Hardware Manufacturers, & WILLIAM NEVILL, of 84, Rowley Street,
Walsall, aforesaid, Stamper, do hereby declare the nature of this invention to be as
follows:-
This invention consists in the herein described improved manufacture of lasso
and other rings, buckles and certain other metal harness fittings whereby the said
articles can be produced more cheaply than heretofore and with as good or in some
cases a better finish.
In carrying out this invention we make the said lasso rings or other said articles
of iron or steel and cover them with sheet brass or other ductile sheet metal or
alloy as follows:-
As an example we will describe this invention as applied to a lasso ring. We
make an iron or steel ring of suitable size either by piercing from the sheet or of wire
or by casting or other well known process. We then take a circular blank of sheet
brass or other ductile metal or alloy with which the ring is required to be covered.
This blank is somewhat larger than the ring. By means of suitable dies worked
in a press or stamp we raise the blank centrally into a cup shape and also raise the
edge of the blank so as to form an annular channel around the cup in which the
ring will lie. We then pierce out the bottom of the said cup and place the ring
in the channel and close down the blank on to the ring thus wholly covering the
same. The covered ring thus formed is or may be stamped in dies which impress
a pattern thereon if required. By treating the blank in the manner above described
the edges do not break. This invention is applied to covering other rings, buckles
and certain other harness fittings similarly as above described with reference to
a lasso ring.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Lasso and other Rings,
Buckles, and certain other Metal Harness Fittings.
We, MATTHEW HARVEY, ALFRED HARVEY and FRANK HARVEY, trading
together as Matthew Harvey & Co., of Glebeland Works, Walsall, Staffordshire,
General Hardware Manufacturers, and WILLIAM NEVILL, late of 84, Rowley
Street, now of 28, Emery Street, Walsall, aforesaid, Stamper do hereby declare
the nature of this invention and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement:-
-
This invention consists in the herein described improved manufacture of lasso
and other rings, buckles and certain other metal harness fittings such as terrets,
whereby the said articles can be produced more cheaply than heretofore and with
as good or in some cases a better finish.
In carrying out this invention we make the said lasso rings or other said article,
from iron or steel and cover them with sheet brass or other ductile sheet metal or

page_text: alloy in the manner which we will now describe by referring to theaccompanying
drawings on which Figs. 1 to 7 both inclusive illustrate our invention as applied
to a lasso or other ring; and the remaining figures illustrate our invention as
applied to buckles.
We will first describe our invention as applied to the manufacture of lasso
and other rings and we will refer to Figs. 1 to 7 both inclusive in which the same
letters of reference indicate the same parts in all the figures. We make an iron
or steel riing A (Fig. 1) of suitable size either by piercing from sheet metal or of
wire or by casting or other well known process. We then take a circular blank B
(Fig. 2) of sheet brass or other ductile metal or alloy with which the ring A is
required to be covered. This blank B is somewhat larger than the ring A. By
means of suitable dies worked in a stamp or press we raise the blank B centrally
at into a cup shape, and we also raise the edge of the blank so as to form an
annular channel d around the cup c in which the ring A will lie leaving a flange e
round the edge. The blank will then have the form shewn in sectional elevation
and in plan by Fig. 3. In stamping the blank the cup is inverted as shewn in
Fig. 7 the bottom die G and the top die or force H (which latter is formed of
lead as usual) having the forms shewn in this figure. This channel d is then
deepened and the cup part c made more shallow and the blank somewhat reduced
in diameter by a pair of dies worked in a stamp or press so that the blank B will
then have the form represented in sectional elevation and in plan by Fig. 4.
We
then pierce out the bottom of the cup c and cut off the flange e round the
channel d so that the latter will then have the form shewn by Fig. 5.
We then
place the ring A in the channel d and close down the edges of blank on to the
ring A thus wholly covering the same as shewn in Fig. 6. The covered ring thus
formed is or may be then stamped in dies which are either plain, or sunk so as to
impress a pattern on the ring, such for instance as shewn by Fig. 7.
By working the blank B as above described, that is by first raising the blank
into a deep cup a with a shallow channel d (Fig. 3) and then increasing the depth
of the channel d and simultaneously reducing the depth of the cup a (Fig. 4) the
metal is not reduced in thickness at the edges f₁of the channel d (Fig. 5)
which prevents these edges breaking when they are closed over the ring A (as
shewn in Figs. 6 and 7) which is an important feature of this invention.
This invention is applied to covering buckles similarly as above described with
reference to a lasso ring as will readily be understood by an examination of the
remaining figures of the drawings of which Fig. 8 represents an iron or steel
buckle frame A which is required to be covered by the blank B (Fig. 9) of sheet
brass or other ductile sheet metal or alloy. Fig. 10 shews this blank when it has
been formed into a cup c with a shallow channel d in which the buckle frame A
will lie and Fig. 11 shews the same blank when the channel has been deepened
and its flange e brought down on a level with the bottom of the cup c; Fig. 12
shews the channel part d after the flange e and bottom of the cup c have been cut
away, and one side of the channel part, corresponding with the bar a¹ of the
buckle to which the tongue is hinged, has been removed because the bar a', being
covered by the leather when the buckle is fixed to the strap, does not require to be
covered by the brass or other metal covering. Fig. 13 shews one side of the
finished covered buckle and a cross section of the same and Fig. 14 shews the other
side of the same where it will be seen that the edges f¹f of the covering when
closed down meet along the centre line of the frame, this line being shewn dotted
in Fig. 13 and full in Fig. 14. In covering such a buckle as shewn by Fig. 16
the blank is passed through the processes above described and formed into the
channel d shewn in Fig. 15 corresponding in form with the buckle (Fig. 16) which
is then placed in the channel and the edges of the latter are by suitable dies
closed over on to the buckle to meet along the same side as the cross bar a³ as
shewn in Fig. 17.
This invention is similarly applied to covering other shaped buckles and terrets.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
The improved method of covering lasso and other rings, buckles and terrets by
ductile sheet metal or alloy herein before described and illustrated by the accom-
panying drawings, which consists in forming from a sheet metal blank in the
manner herein described and illustrated a channel section covering piece of a size
to fit over the ring or other said article to be covered and then closing the edges
of the said channel covering piece on to the said ring or other said article as herein-
before set forth.
