WILLIAM ROBERT LAKE, of the Firm of Hasoltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "AN IMPROVED MANNER OF AND DEVICES FOR
ATTACHING OR SECURING THE HANDLES OF KNIVES AND OTHER TOOLS OR
INSTRUMENTS." A communication from abroad by Claude Couzon-Grimaud, of
Paris, France.
This Invention relates to the manufacture of knives and other instruments or
tools, and consists chiefly in an improved method or manner of and devices for
attaching or securing their handles, the said method presenting considerable
advantages as compared with those hitherto in use, both with respect to strength
and economy.
The said Invention is applicable to all knives which do not fold up or shut, and
is characterized by the fact that the blade of a knife made according to my
Invention is entirely independent of the tang or plate used for attaching it to the
handle, that is to say, the blade and the tang are made as distinct parts.
The blade is attached to a special blade-holder which may be fixed on the handle
by any convenient means.
A blade attached according to my said Invention may, when broken or worn
out, be readily removed from the tang, and another blade may be as readily
attached thereto; moreover the blade will be more easily made than those in
knives of ordinary construction, as it does not require any complicated forging or
fashioning; and should it break whilst being mounted, only a minimum quantity of
steel is lost. Aloreover, in addition to offering the advantages of simplicity and
economy, knives constructed according to my Invention are not of less strength
than others.
In carrying the said Invention into practice I make the blade entirely separate
from the handle, and it is fixed by means of screws between two extensions or
arms of a forked blade-holder, forming part of the tang which is fitted into tho
handle in the usual manner. The said blade holder has a rebate arranged in the
usual manner.
According to a modification of my Invention, the blade-holder, which is'in one

page_text: piece with the tang, as above described, terminates in a rebated flat piece, and the
blade is furnished with a similar rebated piece; in attaching the blade to the
tang the two rebated picces are placed one against the other and secured together
by screws.
In applying my Invention to a knife with a flat tang, the latter is inserted as
usual between the two parts of the handle. This tang is in one piece with a forked
blade holder to which the blade is attached in the manner first herein described.
For kitchen knives, or knives used for culinary purposes, the blade-holder is at
the rear thereof in the form of a ferrule which is fixed on the handle by pins or
tags, or it may be fixed by a screw-threaded rod placed inside the handle and
retained at the end of the latter by a washer or a rivet. In both cases the blade
is inserted and secured in a forked end of the blade-holder.
By the examples above described it will be obvious that this Invention may be
applied in many different manners to all kinds of knives which do not fold or shut
up, such for instance as table, kitchen, butchers, and other knives; also to surgical
instruments, to various edge-tools used in manufactures, and in fact to all blades
which are to be provided with a handle, whatever may be their shape and for
whatever purpose they may be used.
