Improvements in a Cementing Material for Hollow Handled Cutlery,
and in the Method of Applying same.
:-
I, WILLIAM CAMSELL, of 6, Hoyle Street, Sheffield, County of York,
Financial Agent, do hereby declare the nature of my invention to be as follows :-
This invention relates to the formation of a cementing material, or filling, to be
used for securing the hollow handles of knives upon their blades, and for other
similar purposes, the object being to provide a cement that will more effectually
secure the said parts together, and that will not be affected injuriously by
immersion in hot water; it also relates to the method of applying the cement to
hollow metallic handles.
The cement consists of a combination of the following materials, and the pro-
portions given produce a good cement, but I do not bind myself to the said
proportions as they may be considerably modified, being only given as
example.

Improvements in a Cementing Material for Hollow Handled Cutlery,
and in the Method of Applying same.
I, WILLIAM CAMSELL of 6 Hoyle Street, Sheffield, County of York,
Financial Agent, 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 relates to the formation or composition of a cementing material,
or filling, to be used for securing the hollow handles of knives and forks upon
their blades or tangs, and for other similar purposes, the object being to provide a
cement that will more effectually secure the said parts together, and that will not
be affected injuriously, if the said articles are immersed in boiling water; and it
further relates to the method of applying the cement to the hollow metallic
handles.
One form of the cement consists in a combination of the following materials, and
preferably in the given proportions which I find by practice to give excellent
results, but I do not bind myself to the proportions given, as they may be con-
siderably varied, and are only given as an example.
Sulphur, 6 parts out of 12; granulated metal, such as filings, borings, or the
like 4 parts; whitelead part; plaster of paris 1 parts.
These materials are mixed together in a dry state, or they may be mixed

page_text: together wine the sumpour is molten and when cold be broken up and reduced to
powder.
For some purposes, or in some cases I use the following modification.
Sulphur, say 12 lbs. or thereabouts.
Granulated metal 9 lbs.
Charcoal or carbon + lb.
These materials are also mixed in a dry state or may be consolidated by melting
and then be broken and ground to a fine or coarse powder.
I then fill the hollow metallic handles with the cementing materials so made,
and apply heat by any suitable means until the cement becomes plastic or partially
fluid I then press the tang of the knife or other article into the soft cement to
its desired position, and either leave it to cool, or chill it by efficient means.
When the cement is sufficiently plastic, it may be further consolidated in the
handle by pressure, before pressing the tang into it, and if desirable the tangs may
be previously coated with a covering or layer of cement, by dipping thein into
molten cement composed as described, or by heating the tangs and then dipping
them in the cement powder.
Or according to another method I melt the cement in a suitable vessel, to the
desired state of liquifaction, and pour it, or force it through a tubular filler into
the previously heated metallic handles, and immediately insert the tangs as before
mentioned.
Although I have described the process as carried out by manual labour, I may
when it becomes necessary to secure large quantities of handles, use mechanical
means or appliances for holding and filling a number of handles at once, and for
automatically filling them with cementing powder; hoat being applied and main-
tained by gas, but I make no claim to this method.
Having now particularly described and ascertained the nature of my invention,
and in what manner the same may be carried into practice, I declare that what I
claim is :-
1. A cementing material for securing hollow handles upon articles of cutlery
and the like, consisting of the following materials, but the proportions given may
be varied,
Sulphur, 6 parts in 10.
Metal filings, borings, smithy slack, or other metallic compound, 4 parts, to
which may be added a small proportion of whitelead and plaster of paris.
2. A. cementing material for securing hollow handles upon cutlery and the like,
consisting of
Sulphur, in the proportion or thereabouts of 12 lbs. ; metal filings, borings,
smithy slack, or other metallic compound, say 9 lbs. ; carbon, in
form such as charcoal lb., mixed together as a powder.
any suitable
3. The method of securing handles with the cement described, viz., filling the
handles with dry powdered cement, afterwards submitting them to heat until the
cement becomes plastic or sufficiently soft, and then pressing the tang of the article
into position, substantially as hereinbefore described
