Improvements in File Holders and in Files for Use therewith.
I, WILLIAM LLOYD WISE of No. 46 Lincoln s Inn Fields, in the County of Middlesex,
Consulting Engineer and Patent Agent, do hereby declare the nature of this inven-
tion to be as follows:-
•
This invention relates to improvements in file holders adapted to carry files of
various sizes, and in files for use therewith.
The shape of the file is such that the usual tang is dispensed with, thereby
rendering unnecessary the forging operation usually employed for forming such
tangs. Thus the quantity and consequently the value of the steel used in the
manufacture of the smaller sizes of files is diminished to such an extent that when
such a file is worn, a new file may advantageously be taken in lieu of re-cutting
the worn one.
In the annexed sheet of illustrative drawings
Fig. 1 is an elevation of a file holder and a triangular file carried thereby, con-
structed according to this invention.
Fig. 2 is an underside view of the same.
Fig. 3 is a side elevation of the holder.
"
Fig. 4 is a cross section of the same on the line X. Y, Fig. 3. shewing the shape of
the "beak a or that part of the handle which holds the front end of the file.
Fig. 5 is an underside view of the said "beak."
Fig. 6 is a rear end view of the file shewing a hole therein into which engages the
"point" or rear end 6 of the file holder.
As will be readily seen from the drawings, the file holder is made of a rod or strip
of metal bent and shaped to the form shewn, its forward free end or beak a being
formed with a V shaped recess a' and its rear end terminating in a point b.
The triangular file d is formed at its front end with a pyramidal point that engages in
the groove in the beak a which acts as a spring and holds the file against the flat
surface of the body c of the file holder. The other end of the file is formed with
a hole into which the joint or end of the file holder enters as shewn. This
point or end also acts as a spring and thus fulfils the same function as the beak a,
whilst at the same time time preventing the file from disengaging itself from the
handle.
The file may have the form of a perfect triangular prism from its rear end to its
pointed front end which engages with the recess in the beak a of the holder.

COMPLETE SPECIFICATION.
Improvements in File-holders and in Files for Use therewith.
I, WILLIAM LLOYD WISE, of No. 46 Lincoln's Inn Fields, in the County of Middlesex,
Consulting Engineer and Patent Agent, do hereby declare the nature of this inven-
tion 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 improvements in file holders adapted to carry files of various
sizes. and in files for use therewith.

page_text: The shape of the file is such that the usual tang is dispensed with, thereby
rendering unnecessary the forging operation usually employed for forming such
tang. Thus the quantity and consequently the value of the steel used in the manu-
facture of the smaller sizes of files is diminished to such an extent that when such
a file is worn, a new file may advantageously be taken in lieu of re-cutting the
worn one.
Referring to the sheet of illustrative drawings filed with my Provisional Speci-
fication
Fig. 1 is an elevation of a file holder and a triangular file carried thereby con-
structed according to this invention.
Fig. 2 is an underside view of the same.
Fig. 3 is a side elevation of the holder.
Fig. 4 is a sectional elevation of the same on the line X Y Fig. 3 shewing the shape
of the beak a or that part of the handle which holds the front end of the file.
Fig. 5 is an underside view of the said "beak."
Fig. 6 is a rear end view of the file shewing a hole therein into which engages the
"point
or rear end of the file holder.
As will be readily seen from the drawings, the file holder is made of a rod or strip
of metal bent and shaped to the form shewn, its forward free end or beak a being
formed with a V-shaped recess a¹ and its rear end terminating in a point b.
The triangular file d is formed at its front end with a pyramidal point that
engages in the groove a¹ in the beak a which acts as a spring and holds the file
against the flat surface of the body c of the file holder. The other end of the file
is formed with a hole 6' into which the point or end 6 of the file holder enters
as shewn. This point or end also acts as a spring and thus fulfils the same function
as the beak a, whilst at the same time preventing the file from disengaging itself
from the handle.
The file may have the form of a perfect triangular prism from its recessed rear end
to its pointed front end which enters the recess in the beak a of the holder.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. The hereinabove described metallic file holder.
2. A file having the form of a triangular prism with a recess at one end for the
purpose specified.
3. The combination of a triangular file and a holder such as described.
