PROVISIONAL SPECIFICATION left by the said Moska Merichenski at the
Office of the Commissioners of Patents on the 29th April 1882.
MOSKA MERICHENSKI of Poplar in the County of Middlesex
IMPROVED METHOD OF, OR CONTRIVANCE FOR, SECURING THE BLADES OF KNIVES
AND OTHER EDGE TOOLS IN THEIR HANDLES,'
"
"A
NEW
OR
My invention has for its object to effectually secure the blades of knives and
other edge tools in their handles and consists in forming the blade of a knife or
tool with a split-spring "tang" which is of a square, rectangular, round or oval
section and solid for a short distance from the shoulder of the blade whence it is
split into two portions, each of which is formed at its end with a flat hook or
catch.
The hole in the handle for the reception of the tang of the blade is made of a
suitable form to receive the solid portion of the tang and of a length or depth
equivalent to the distance between the shoulder of the blade and the flats of the
hooks or catches on the split ends of the tang where the hole is slightly enlarged
so as to form a wider cavity for the reception of the hooks or catches of the tang
when expanded as hereafter more particularly described
To secure the blade in its handle the split ends of the tang are pressed together
and the tang pushed down through the square, rectangular or other shaped hole in
the handle until its hooks or catches arrive at the enlargement or cavity when the
spring or outward tendency of the split portions of the tang causes them to spread
apart and their hooks or catches taking on to the upper corners or edges of the
cavity locks the blade in position-The hole and cavity having been previously
partially filled with cement the blade is thereby effectually secured in its handle.

MOSKA MERICHENSKI of Poplar in the County of Middlesex
A NEW
OR
IMPROVED METHOD OF OR CONTRIVANCE FOR SECURING THE BLADES OF KNIVES
AND OTHER EDGE TOOLS IN THEIR HANDLES
"
My Invention has for its object to effectually secure the blades of knives and
other edge tools in their handles, and is illustrated by Figures 1 to 7 on the
accompanying drawing, like letters of reference indicating corresponding parts in
the respective figures.
My Invention consists in forming the blade a of a knife or tool with a split
spring "tang" b (figures 1 and 3) which is of a square, rectangular (as shewn),
round, or oval, section, and solid for a short distance c from the shoulder d of the
blade a whence it is split into two portions e, e¹, each of which is formed at its end
with a flat hook or catch f.fl.
he hole g (see figure 2) in the handle for the reception of the "tang" b of the
blade a is made of a suitable form to receive the solid portion c of the "tang" b
and of a length or depth equivalent to the distance between the shoulder d of the
blade a and the flats of the hooks or catches f. f' where the hole is slightly enlarged
so as to form a wider cavity g' for the reception of the hooks or catches f. f¹ of the
tang" b when expanded as hereafter more particularly described.
";
To secure the blade a in its handle h the split ends e. e¹ of the "tang" b are
pressed together and the "tang "b pushed down through the square, rectangular
(as shewn) or other shaped hole g in the handle h until its hooks or catches f. f'
arrive at the enlargement or cavity gl when the spring or outward tendency of the
split portions e. c. of the "tang "b causes them to spread apart and their hooks or
catches ff. taking onto the upper corners or edges of the cavity g' locks the
blade a in position, as seen in figure 3. The hole g and cavity g¹ having been
previously partially filled with cement the blade a is thereby effectually secured in
its handle .
Or if desired a wedge i (see figure 4) may be used in combination with the split
"tang", that is to say, the wedge i will occupy the lower end of the bandle '
with its sharp end upwards when the "tang" 6' being pressed down into the
handle h' its split ends will be separated or expanded by the wedge i as shewn.
In this case also if preferred the split ends of the " tang" as shewn in figure 6
may be "bowed" or curved outwards in lieu of being straight as in figure 4.
According to another plan one portion of the spring "tang" b³ (figure 5) in lieu
of having a hook or catch at its end as shewn in figures 1 and 3, may be made
straight, and the cavity g² shaped accordingly. In some cases it may be necessary
to use three or four split or spring portions j. j.j. to the "tang" b* each provided
with a hook or catch, as shewn in figure 7.
Or if desired the spring hooks or catches may be inverted and hinged to or
formed at the end of the solid portion of the " tang" on each side thereof, so that
when pressed against the latter they can readily be inserted into the handle, and
on arriving at the enlarged cavity therein, will fly outwards or expand, thereby
securing the blade in its handle.
Having now described and particularly ascertained the nature of my said
Invention and the manner in which the same is or may be used or carried into

page_text: effect, I would observe in conclusion that what I consider novel and original and
therefore claim as my Invention is:-
Securing the blades of knives and other edge tools in their handles, substantially
as hereinbefore described and illustrated by Figures 1. 2. 3. 5. and 7 on the
accompanying drawing.
In Witness Whereof I the said Moska Merichenski have hereunto set my
hand and seal this 25th day of October in the year of our Lord One
thousand eight hundred and eighty two.
