PROVISIONAL SPECIFICATION.
Improvements in Carving-fork Guards.
I, ALFRED COPLEY of 235 Rockingham Street, Sheffield, in the County of York,
Fork Manufacturer, do hereby declare the nature of my invention to be as follows:-
This invention of improvements in the guards of carving forks, refers particularly
to the spring arrangement for retaining the guard in its open, and its closed positions.
In carrying out the invention, I dispense with the oblong hole usually required, and
formed in the shank of the fork to receive the V spring, and I simply make a square
hole of comparatively small size, terminating in a round hole to receive a small spiral
or coiled spring, the action of which is vertical.
The butt end or joint piece of the guard is made with two flats which represent the
two positions of the guard, that is either open or shut, and it is provided with a piu
hole to receive the pin or axis upon which it turns.
I prefer to have an intermediate flat bearing between the spring and the joint piece
of the guard to ensure a regular and easy movement.
The butt end of guard fills the square hole in the shank, thus preventing the
entrance of dirt.

COMPLETE SPECIFICATION.
Improvements in Carving-fork Guards.
1, ALFRED COPLEY of 235, Rockingham Street, Sheffield in the County of York,
Fork Manufacturer, 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 of improvements in the guards of carving forks, refers particularly
to the spring arrangement for retaining the guard in its open, and its closed positions.
The method of carrying the invention into practice is shown in the annexed sheet
of drawings, in which like letters indicate like parts in any of the figures.
Fig. 1. represents a carving fork, partly in section, to show arrangement of spring.
Fig. 2. the guard.
Fig. 3. the spring.
Fig. 4. the bearing piece.
In carrying out the invention I dispense with the oblong hole usually required to
receive the long V spring, and formed in the sbank or body of the fork, and I make
instead thereof a square hole A, of comparatively small size, and in the bottom of the
square hole I make a circular hole B, in which I place a small coiled spring C, shown
in Fig. 3, the action of which is vertical.
The guard D, is of ordinary shape, but the end or butt D' is made with two flats,
which are in accordance with the two positions of the guard, that is, when open and
when closed, and it is also provided with a pin-hole as usual to form the means of
securing it to the shank or body E, and the axis upon which it turns.
Instead of allowing the end of the coiled spring C, to bear against the butt of the
guard directly, nse an intermediate bearing piece F, shown in Fig. 4, and having a
short shank to enter the first coil of the spring; this ensures a regular and easy action
of the guard in turning from one flat to the other.
гр.

page_text: When the guard is fixed to the shank the butt end compresses the spring, so as to
bring the pin-hole opposite the corresponding holes in the shank, the pin is then
inserted and filed off.
The pressure of the spring upon the butt retains the guard in the open and closed
positions.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same may be performed, I declare that what I
claim is
1-The improvements in carving fork guards consisting of the combination with a
guard having two flats upon its butt end, of a spiral spring working vertically under
the guard, with an intermediate bearing piece, substantially as hereinbefore described.
and illustrated.
2-In the construction of carving fork guards, making a square or oblong hole in
the fork, for the butt of the guard, and a round hole for a spiral or coiled spring, and
.holding the guard in position by the action of the spring upon the butt, with or
without an intermediate piece, substantially as hereinbefore described and shown.
Dated the 6th day of November 1890.
