Improvements in Files.
CHARLES GARFITT Machine Knife Manufacturer Cross Scythes Works
Sheffield do hereby declare the nature of this invention to be as follows:-
-
These improvements have for their object greater security, increase of working
power, and convenience in the use of engineers, & similar files.
In carrying out my invention, I perforate the file at the handle or tang end with
one or more holes, and fasten in said hole one or more pieces of iron or steel of
suitable thickness and shape which project out at right angles a suitable distance
from the file, or to produce the same result two or more pieces of steel of a suitable
width are pierced at the tang or handle end of the file, and each piece bent up at
right angles on a side of the file.

Improvements in Files.
I, CHARLES GArfitt, of "Cross Scythes" Works, Sheffield, in the County of
York, Machine Knife 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 :-
These improvements have for their object greater security, increase of working
power, and convenience in the use of engineers and similar files.
In carrying out my invention, I perforate the file at or near the handle or tang
end with one or more holes, and fasten in said hole or holes, one or more pieces of
iron or steel of suitable thickness or shape, which project out at right, or nearly
right angles a suitable distance from the file; or to produce the same result, two or
more pieces of steel of a suitable width are pierced at or near the tang or handle
end of the file, and each piece bent up at right, or nearly right angles on a side
of the file.
By the use of these pins, or their equivalents, injury to the users hand when the
file slips is prevented, and in addition, the pin or its equivalent forms a rest for the
fingers thereby enabling greater pressure to be applied; and an incidental advantage
gained by the use of files made according to my invention, is that that when laid
down upon a bench or other surface, it rests upon the point and one of the pins or
projecting pieces of steel equivalent thereto. By so resting the whole of the faces
of the file are free from contact with the grease or dirt which is generally present
in workshops and upon machines.
My improvements are equally applicable to all descriptions of files, whether they
are formed with a tang for insertion in a handle, or formed integrally with the
handle as shewn in Figs. 1 and 2 of the accompanying drawings in which :-
Fig. 1 is a view of the face and handle of a reaper knife file according to my
invention

page_text: Fig. 2 is an edge view of same.
Fig. 3 is a face view of part of a file, in which the file is pierced, and the two
bent up strips serve the same purpose as the pin shewn in Figs. 1 and 2.
Fig. 4 is an edge view of same.
Fig. 5 is an edge view of a modified form of guarded file.
Fig. 6 is an end view of same.
A indicates the blade, or working face of the file; B the handle, in this case
formed integrally with the blade; and C the pin, which may be driven, screwed,
or welded into a hole e in the file.
In Figs. 3 and 4, A is as before, the blade or working face of the file, and B its
tang, (which fits into a handle), but in this case the file, at a point between the
tang and the blade, is pierced by an aperture or apertures D, three sides d, of each
of which are cut right through the file, but the fourth side d' is not cut, but bent
up (as shewn) at a right angle, or approximating thereto so as to form a projecting
piece C which fulfils the same function as the pin. Two of these projecting
pieces are shewn, but more may be employed without departing from my invention;
and the apertures D may be of any suitable shape. In some cases I weld the
projecting pin or piece C to the file blank.
In Figs. 5 and 6, the tang B of the file is broad, and upon each side of it is
fastened a piece of wood, or other suitable material E. These two pieces are
fastened to the tang by rivets e, and are so shaped as to form a handle. Each
piece E has a projection C forming part of it which projections form guards as
before.
A softer material may in some cases be used for the pins, thus preventing the
possibility of injuring the "work" when the file slips.
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-
:-
1. A file, of any description, having a pin or equivalent projections near the
handle end of the file, substantially as and for the purpose hereinbefore described.
2. Forming a pin or equivalent projecting pieces on a file, for the purpose of
guarding and protecting the hand of the user, substantially as shewn and described.
3. The combined file and pin, substantially as shewn and described with reference
to Figs. 1 and 2.
4. The combined file and projections, substantially as shewn and described with
. reference to Figs. 3 and 4.
5. The combination of a file with a pin or ***alent projections, substantially as
shewn and described.
