I CHARLES IBBOTSON of 58 Cambridge Street Sheffield in the County of York
Cutlery Manufacturer, do hereby declare the nature of my said Invention for
"IMPROVEMENTS IN THE CONSTRUCTION AND MANUFACTURE OF HANDLES FOR
TABLE CUTLERY, SUCH AS KNIVES AND FORKS ALSO THE HANDLES OF SHEATH
KNIVES, UMBRELLA AND WALKING STICKS AND THE LIKE ARTICLES," and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :—
"
This invention relates to improvements or modifications of my patent numbered
10,806, "Provisional Specification for which I filed on 31st day of July, 1884,
and as the subject matter and the object to be attained by the present Invention,
is the same, or similar to that just referred to, (the principal difference being in the
manner the same is to be performed,) I will first recite the Specification of my
Patent number 10,806, (8) which is as follows :—
"This Invention relates to the Construction of the handles of table Cutlery and
"the handles of other similar articles with tangs.”
if
"
"
"This Invention consists essentially in the method of securing thin scales of
ivory, pearl, tortoise-shell and other substances to foundations of metal, wood,
or metal and wood combined, and other similar and inexpensive substances, the
"said scales being secured without being rivetted, being retained in position
simply by the pressure of a metal flange turned over them, or dovetailed, or
otherwise, the said flange being secured to the edges of the said foundation by
16 soldering, rivetting, or otherwise, the foundation being constructed in two parts
or divided longitudinally, so as to open to admit the scale, and so as to shut to
cause the flange to close onto the scales, the foundation being retained in a close
position by the insertion of a single or double tang therein; In the construction
"of a handle for a single tang, the foundation is made in the form of a hinge,
a projection on one side fitting into a recess in the opposite side, the tang being
"inserted in a hole cast or formed longitudinally therein, so that when forced into
position it locks the two sides together, and the scales and foundation form one
complete handle,

page_text: "In the construction of a handle for a double tang, the foundation is divided in
" the centre of its width and a hole is cast or formed longitudinally in each side,
"
one tang being inserted in each hole and being driven in tight (by preferenco
" the tangs are taper) draws each side of the foundation together and secures the
".scales in position, The flange projects above the foundation and can be turned
"over or dovetailed to hold the scales, or it can be straight, and the scales secured
by a ferrule or cap or similar appliances; the scales are inserted on the foundation
so as to cover it, and between the edges of the flange, and the sides of the flange
being brought together, by the insertion of the tang or tangs press onto the edges
" of the scales and secure them firmly to the foundation.
"
Ef
"
"
The flango can be of thin sheet metal and surround the sides and end of the
"foundation, and spring like a pair of sugar tongs, and the sides of the foundation
can be secured to the flange so as to open and close therewith."
"
The handles which form the subject of my present invention are made up in
a manner similar to those described in the foregoing Specification and consists of a
frame or rim called the flange of the handle which is constructed out of a strip of
sheet metal of the required breadth and which may be made as thin as is consistent
with the form and strength required, this strip may be stamped rolled or otherwise
turned over at each edge; it may be made with a groove or recess along each edgo
so as to form a cavity or double edged flange to receive the scales, this rim frame
or flange may be made of a variety of sections and may be either flat or canted,
fluted or round, In the event of the handle being required to be rounded on the
edges the flange may also be made round so as to turn over on to the scale and
secure it on to the foundation without any extra groove or recess,-In proparing
handles of this construction with a large or ornamental head it may be stamped in
two halves and afterwards soldered together leaving the rim to be bent or grooved
For recessed for the reception of the scales as described.
A foundation of white metal or other equivalent material is cast onto and within
this rim, frame, or flange, (which has been previously prepared by turning or other
process) such foundation being made either hollow, or solid, or partly solid, or in
skeleton shape, and serving to form a support for the scales of the handle to rest
upon and also serving to close and secure together the several parts which constitute
the handle.
The essential features of my present invention, consist in the manner in which
the frame, rim, or flange, of the handle is secured to the foundation, and to the
construction, and material used in such foundation, and also in constructing the
foundation of the handle, partly of metallic substanco, and partly of wood or other
equivalent material, in such a manner that the combination forms a solid and
durable handle or haft, and at the same time admitting of the employment of a
greater variety in the material and design of which the scales of the handle may be
constructed.
The method of carrying out this invention may be better ascertained on reference
to the accompanying drawings.
Figure 1. represents a handle (part of the scale being removed) constructed in
the solid form with a combination of metallic and wooden or other
equivalent material.
A. A. is a part of the foundation made of wood or other equivalent material and
which is made a little less than the frame, rim, or flango.
B, B, B, reprosents the frame, rim, or flange, of the handle which may be stamped
rolled and bent of the required form.
C, C represents the scalo or scales which may be made of a great variety of
material and design.
D. D, is the metallic portion of the foundation.
E. E. is the tang of the blade.
K, represents the blade.
Figure 2 is a cross section through the handle on the line L, M, (enlarged).

page_text: On reference to the foregoing figures it will be seen that the scale C, rests upon
the foundation A, and is secured by the flango part of the rim, or frame B, when
the rim, and the scales, with the wooden foundation are fitted together a space is
left between the foundation A, and the frame or rim B¹, into this space the white
metal or other equivalent material, is run or cast, the rim having been previously
prepared so as to secure the adhesion, or fusion, of the two metals which unite at
the bolster ond of the handle as shewn by the dotted line at H. H. thereby securing
the several parts which form the handle, which bas by the process just described
become solid, the hole is then drilled through the white metal and the wood
foundation to receive the tang, which is then inserted in the usual way, and may
be made long enough to go right through so as to be rivetted at the end of the
handle furthest from the blade.
Figure 3, represents a handle with a metallic foundation, only constructed in a
Skeleton shape, this foundation being run or cast into the frame in a similar
manner to that described in figure 1 but in this case a temporary intermediate
foundation like a coro box or mould, is used, together with temporary scales, fitted
to and adapted to work in conjunction with the core box or mould, so that they
can be removed after the foundation D. D. with the projections G. G., have been
cast, for this purpose a slit is provided in each of the temporary scales as shewn
at F. F. which admits of the white metal being sawn through; after which the
frame B. B. B, and the foundation D. D. with the projections G. G. will all spring
open and so release the temporary scales, mould, or coro box, after the holes for the
ting have been provided through the projections G. G. and the bolster end of the
foundation the permanent scales can be placed within the frame B. B. B. and resting
upon the foundation D. D. the tang of the blade E. E. will then be inserted as
previously described, and the whole firmnly secured together.
Figure 4 is a cross section of the saine through the line L. M. (enlarged).
Figure 5 illustrates the rim frame or flange of the handle before the foundations
are run or cast in.
Figure 6. is a section of the same through the line L. M. (enlarged).
Figures 7. 8. 9. & 10 represent some other sections which may be used in the
construction of the rim frame or flange illustrated in figures 5 & G.
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;
(1.) The manner in which the Frame rim or flango of the handle is secured
to the Foundation by casting or running the said Foundation into the spaces left
between a permanent Foundation to be inade of wood or other aquivalent material
or into spaces provided by a mould or core box to be temporarily inserted for
the purpose of forming a Skeleton shape of Foundation in the manner herein
before described.
(2.) The construction of the handle partly of metallic substance and partly of
wood or other equivalent material in conjunction with the method of securing the
same together by casting or running the metallic portion of the Foundation
around into and about the said handle in the manner hereinbefore described and
illustrated by the accompanying Drawings as shewn in figures 1. 2. 3. 4 5 6 7 8 9
& 10.
