PROVISIONAL SPECIFICATION.
Improved Means of Securing Table Cutlery and the like to.
Interchangeable Handles.
I, ALFRED SANCTO, of No. 32 Pyebank, Sheffield, Engineer, do hereby declare
the nature of this invention to be as follows:-
The object of iny invention is to permit of greater compensation for wear by use
and also for variations in the locking parts of interchangeable handle cutlery,
while to some extent reducing the cost of manufacture by substitution of parts
more easily produced.
In carrying out my invention, I prefer to use an ordinary metallic bolster or
ferrule suitably shaped to receive the tang end of blade and projecting sufficiently
from the end of the handle to receive, between bolster part and handle, a revolving
collar or nut having a coarse or double screw thread formed continuously for its
whole depth; upon the upper edges of the blade tangs I form notches of
corresponding pitch and shape into which the threads in the nut enter so that by
rotating said nut the blade will be screwed up firmly shoulder to bolster irrespective
of even considerable longitudinal variations in the dimensions of the several parts
intended to be interchanged in any set of table cutlery having detachable handles.
Dated this 25th day of September 1895.

Improved Means of Securing Table Cutlery and the like to
Interchangeable Handles.
I, ALFRED SANCTO, of No. 32 Pyebank, Sheffield, Engineer, 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 :-
The object of my invention is to permit of greater compensation for wear by use
and for variations in the locking parts of interchangeable handle cutlery, while to
some extent reducing the cost of manufacture by substitution of parts more easily
produced.
In carrying out my invention, I prefer to use an ordinary metallic bolster and
ferrule suitably shaped to receive the taug end of blade and projecting sufficiently
from the end of the handie to receive, between bolster part and handle, a revolving
collar or nut having a coarse or double screw thread formed continuously for
nearly its whole depth; upon the upper edges of the blade tangs I form notches of
corresponding pitch and shape into which the threads in the nut enter so that by
rotating said nut in the proper direction the blade will be screwed up firmly with
its shoulder to bolster jaws irrespective of even considerable longitudinal variations
in the dimensions of the several parts intended to be interchanged in any set of
table cutlery having detachable handles.
And in order that my said invention may be thoroughly understood, I will

page_text: Dow further describe the same by reference to the annexed sheet of drawings:
wherein
Fig. 1, illustrates by plan and elevation, partly sectional, my revolving collar or
screw nut, a, the raised parts whereof may be beaded, engraved or ornamented and
so afford better hold for the fingers.
Fig. 2, likewise by plan and part sectional elevation represents a ferrule, b, with
washer bearing upon which nut, a, revolves, the lower portion being fitted to
handle as usual.
Fig. 3, represents a portion of a knife blade, c, with the requisite notches in both
edges of tang and the extreme end of said tang reduced to fit into the central hole
in tail of bolster, d, Fig. 5.
Fig. 4, represents a complete table knife with a detachable handle, e; a portion
of handle and of all the parts constituting the locking device, being supposed to be
removed to reveal the actual positious of each as used in combination.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
In table cutlery and the like and in interchangeable handles therefor, the device
of a collar or screw nut revolving around the upper edges of the blade tang, said
tang having corresponding notches therein operating as portions of a screw when
within the said nut which in combination with an ordinary metallic bolster and a
ferrule washer constitute durable and reliable means for fastening and releasing
such handles from cutlery and the like appliances, substantially as herein described
and illustrated.
Dated this 22nd day of February 1896.
