page_text: NOW KNOW YE, that I, the said Hugh Cochrane, do hereby declarc
the nature of the said Invention to be as follows:
The object of this Invention is to construct the handles of table
knives and forks with thin scales or plates of ivory, bone, horn, glass,
pearl, or other such like suitable material at each side of the handle, in
place of forming the handle of a solid piece of ivory or other material
as is now usual. For this purpose a tang or tail piece is formed on or
attached to the blade or to a neck piece attached to the blade, and to the
top and bottom of this tang or tail piece is connected a bent strip of
metal to form the back, front, and end of the handle; around each edge
of the strip of metal is a recess to receive the edges of a thin scale or
plate of ivory, bone, horn, glass, pearl, or other suitable material, and
the edges of the strip of metal are then turned or burnished over the
edges of the thin scales, so as to slightly overlap them and hold the
scales in their place..
To further secure the scales cement may if desired be used to support
, and hold them, or they may if desired be held by cement alone without
the edges of the metal strip being bent over to cause them to overlap
the scales.
In the Drawings hereunto annexed I have shewn various views of a
table knife with its handle formed in this manner. Figures 1 and 2
shew a side and edge view of the knife blade with its tang or tail piece;
Figure 3 shews a side view of the blade with the metal strip or moulding
attached to its tang; Figure 4 shews a side view; and Figure 5 a
longitudinal section of the finished knife.
•
In these Figures a is the tang or tail piece formed on or attached to
the tail end of the blade; b is the metal strip or moulding attached by
rivets c, c, to the back and front of the tang; d, d, are the scales or
plates of ivory or other material. The metal strip or moulding 6 is first
rolled or formed with recesses along both its edges, as shewn by the
section, Figure 6, it is then bent to the form of handle desired, and
secured by the rivets c to the tail or tang of the blade. When this has
been done the scales of ivory or other material are laid into the recessed
beds so formed for them around the edges of the metal strips b, and the
edges of these strips are then burnished over or turned inwards to
overlap the edges of the scales, as shewn in the section, Figure 7. In.
order that the handle. may not be too heavy, the tang or tail piece is

page_text: made shorter than the handle; as shewn, and the space between the end
of the tang and the end of the handle may be filled in with cement or
other suitable filling, or may be left hollow. If the tangs are of iron,
cement or other material may also be interposed between the tang and
the ivory or other scales to prevent any injury to the appearance of the
scales by reason of the tangs becoming rusty. Or the tangs may be
tinned or coated with nickel or other material to prevent their becoming
rusty, or they may be made of metal not liable to rust.
made shorter than the handle; as shewn, and the space between the end
of the tang and the end of the handle may be filled in with cement or
other suitable filling, or may be left hollow. If the tangs are of iron,
cement or other material may also be interposed between the tang and
the ivory or other scales to prevent any injury to the appearance of the
scales by reason of the tangs becoming rusty. Or the tangs may be
tinned or coated with nickel or other material to prevent their becoming
rusty, or they may be made of metal not liable to rust.
The handles of all descriptions of table knives and forks may be
formed in the above manner.
Having thus described the nature of my Invention, and the manner
of performing the same, I would have it understood that I claim,―
1. The construction of the handles of table knives and forks with
scales or plates of ivory or other material at the sides, secured by
burnishing or turning over the edges of a metal back, front, and end
piece, substantially as herein described.
(2.) The construction of the handles of table knives and forks,
substantially as herein described.
In witness whereof, I, the said Hugh Cochrane, have hereunto set
my hand and scal, this Twenty-eighth day of March, in the
year of our Lord One thousand eight hundred and seventy-three.
