I, THOMAS RICHARDSON ELLIN Brincliffe Mount, Sheffield, in the County of
York Manufacturer do hereby declare the nature of my said invention for IMPROVE-
MENTS IN THE CONSTRUCTION OF SPRING CUTLERY, AND OTHER SIMILAR CLOSING
ARTICLES, to be as follows:-
This invention refers more particularly to one ended knives, that is knives in
which the blade or blades are secured to one end only, the object of the invention
being to reduce the cost of manufacture.
In carrying out my invention in making a knife for example, I take a strip of
any suitable metal, and of proper length and breadth, and I bend it transversely
across the centre, so as to nearly close the parts together, and thus form the two
sides of the knife, between which the blades will be placed and secured by pins
in the usual manner.
The bent metal scales so formed may be finished off without further addition; or
outer scales of horn or other material may be secured to the outside as desired.
In a single blade knife, the blade is secured at the open end of the scales by a
pin in the usual manner, the spring is secured near the end where the scale is bent
over or doubled, by passing a pin through it, and the extreme end fits into a slot
cut out of the said bent end, through which it may project if desired and be pro-
vided with a hole for a split ring or other device. The opposite end of the spring
rests against the butt end of the blade and act in the usual way.
When adapted for lobster" or divided springs for two or more bladed knives
(for example) the spring head is passed into a hole made through the centre of the
bend of the scales, being flush with or projecting from the outside as may be desired,
and such projection may be utilized for various purposes.
By my method I save a head pin in the spring, as well as the head of the
spring as usually made, and the knife will take in a blade longer in proportion
than usual,

Improvements in the Construction of Spring Cutlery and other
similar Closing Articles.
I, THOMAS RICHARDSON ELLIN Brincliffe Mount, Sheffield, in the County of
York Manufacturer, do hereby declare the nature of my invention for IMPROVE-
MENTS IN THE CONSTRUCTION OF SPRING CUTLERY, AND OTHER SIMILAR CLOSING
ARTICLES, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement, that is to say:-
-
This invention more particularly refers to Knives in which the blade or blades
are secured to one end only, the object of the invention being to simplify the
construction and thereby reduce the cost of manufacture.
And so that my invention may be clearly understood I have annexed hereto a
sheet of illustrative drawings representing my invention applied to various pieces
of cutlery.
Fig. 1 represents a Knife made according to my invention, and various parts
thereof.
Fig. 2, represents a double-blade Knife with button hook, made according to my
invention.
Fig. 3, a Knife with closing button hook and blade.
Fig. 4, a Gardeners budding Knife.
Fig. 5, a Jack Knife.
In carrying out my invention in the construction of a single blade Knife for
example, as shown in Fig. 1, I take a strip of any suitable metal and shape it to
form A, I then bend or double it back in the middle, so as to form two scales as
shown at B, and C, the recess D being for the purpose of allowing the end of the
spring E, to take a bearing against the edge of the metal, and if desired it may
project beyond the end, and be utilized, as a turnscrew or similar device as shown
in the drawing.
It will thus be seen that the spring in this Knife only requires one pin to secure
it in the required position, this is marked G in Fig. 1, the pressure of the spring
when the blade is being opened is taken by the pin G, and the edge of the
scale at H.
The holes I are only used in Smokers Knives for the purpose of cutting off the
ends of Cigars and form no part of my invention.
The blade is placed between the scales B, in connection with the spring E, and
secured by a pin in the usual manner.
The metal scales B may constitute the outside of the Knife, being polished, silver
plated, or otherwise finished; or scales of ivory, horn or other substances may be
attached thereto.
When a divided. or "lobster" spring F is used, as for instance in a two-blade
Knife, seen in Fig. 2, instead of making a notch or recess such as D in the side of
the scales, it is made through the centre, and the projecting end of the spring may
be utilized as a button hook J, or may be cut off flush with the end of the scale
or knife.

page_text: In Fig. 3, I have shown a double blade Knife the metallic part being covered
with ivory scales and the end of the spring formed into an attachment for a
split ring.
In the case of a budding Knife such as shown in Fig. 4, the present mode of
manufacture is to slit (by means of a saw) a suitable aperture or slot in the haft to
receive the blade and spring, and to pass the pins K through the ivory of which
the haft is usually made and the blade also through the ivory and the spring thus
rendering the half very liable to fracture.
My invention obviates this as the blade with the spring is first secured between
the metallic scales as before described, and then inserted, and secured in the slotted
haft, the strain of the spring is thus borne by the metallic scales.
I consider that by the use of my invention in the construction of Spring Knives,
and other articles of a similar character intended to close into their handles,
I dispense with the "head" of the spring as usually made, as well as the pin
called a head pin; also a Knife make after my plan will take a blade longer in
proportion than usual.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed and carried into
practice, I declare that what I claim is :-
1. In the manufacture of Spring Knives, and other instruments that close or
shut up into their handles, the use of scales made by folding a strip of metal
transversely (as shown in Fig. 1,) having a side notch or shown in Fig. 1,) having
a side notch or recess, or a central hole, to receive the end of the spring, and to
form a bearing or resistance point, against which the spring presses, when in
action, for the purpose specified, and substantially as hereinbefore described and
illustrated.
2. In Spring Knives and similar closing articles, the arrangement of the spring
so that it takes a bearing against the edge of the scale, and is secured by one pin
substantially as herein described and shown.
