Improvements in Handles for Files and other Tools or Articles.
I, WILLIAM FAIRBURN HART, of the General Assurance Buildings, No. 1,
East Parade, Leeds, in the County of York, Patent Agent, (a communication to
me from abroad by John William Payler of the City of Detroit, in the County
of Wayne, in the State of Michigan, United States of America, Mechanical
Engineer) do hereby declare the nature of this invention to be as follows:-
This invention, while applicable to other tools and articles, is more especially
designed to be used as a handle or "carrier" for files for surface and general filing,
or abraiding of hard surfaces.
The invention consists of a handle curved to form an off set which brings its
hand grasping portion out of line with the file or tool holding portion (hereafter
termed the "shank ") which is made of socket like construction adapted to receive
and have the tang or shank of the file, tool, or other article as ordinarily formed
and constructed secured within it.
The "shank" portion of the handle or carrier and its hand grasping portion may
be cast or otherwise formed and constructed in one piece, or in lieu of the handlo
a socket or a tang may be provided for the attachment of a suitable handle. Said
stock or shank is of a curved or off. set construction, so as to form a socket (having
a flattened bottom) adapted to receive within it a plug or filling of wood or any
suitable material. In the bottom of the plug is formed a longitudinal groove in
which the taug of the file, tool, or other article is secured in such a manner that
the bottom surface of the handle or carrier and the operating face of the file, tool,
or other article will be approximately on the same plane. The "shank" and hand
grasping portions are connected together by a curved portion which forms part of
the shank of the handle or carrier, and also serves to bring the said portions in
substantially parallel relation with each other. The curved connection is preferably
made from the forward or largest end of the shank but it may be made from any
other part thereof. The stock may either be tanged shaped to provide for it being
driven into the handle proper, or it may be constructed in socket form to receive
a handle partly within it, or of knife handle form, or the handle proper may be cast
or otherwise formed and constructed complete with the tool holding socket and
shank. The curved portion of the shank may be prolonged so as to rest upon the
file, tool, or other article, a recess being provided between tool holding socket and
the portion that rests upon the file. The hole in the socket may extend the whole
length thereof, or only partly through it; but it is preferred to make it pass
entirely through it for more conveniently removing or extracting the plug.
In some cases the improved handle or carrier may be constructed so that one or
more sockets (provided with a plug or filling of wood or other material) is or are
made to slide on a suitable bar. The bar is made of sufficient length to enclose
the file, tool, or other article between the sockets, or between a socket and a suitable
stop, and is then prolonged at one or both ends to allow of the attachment of one
or more handles for the use of two persons, as, say for instance, in filing a key
seat in the hub of a large wheel.

Improvements in Handles for Files and other Tools or Articles.
I, WILLIAM FAIRBURN HART, of the General Assurance Buildings, No. 1,
East Parade, Leeds, in the County of York, Patent Agent, (a communication to me
from abroad by John William Payler of the City of Detroit, in the County of
Wayne, in the State of Michigan, United States of America, Mechanical Engineer)
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, while applicable to other tools and articles, is more especially
designed to be used as a handle or "carrier" for files for surface and general filing,
or abraiding of hard surfaces.
The invention consists of a handle curved to form an off set which brings its
band grasping portion out of line with the file or tool holding portion (hereafter
termed the "shank") which is made of socket like construction adapted to receive
and have the tang or shank of the file, tool, or other article as ordinarily formed
and constructed secured within it.
In the drawings:-
Fig. 1. represents a longitudinal section of a handle, or carrier embodying my
invention and having a file shown only in part secured therein.
Fig. 2. is a transverse section of the same upon the line y. y, Fig. 1.
Figs. 3, 4 and 5. are partly longitudinal sections of the handle or "carrier."
Like parts in all views are marked with the same letters of reference.
In
The shank portion A of the handle or carrier and its hand grasping portion B
may be cast or otherwise formed and constructed in one piece, or in lieu of the
handle B a socket or tang e may be provided for the attachment of a suitable
handle B. Said stock or shank is of a curved or off set construction, so as to form
a socket (having a flattened bottom) adapted to receive within it a plug or filling of
wood or any suitable material C. In the bottom of the plug is formed a longitudinal
groove c' in which the tang d of the file, tool, or other article C is secured in such
a manner that the bottom surface of the handle or carrier and the operating face of
the file, tool, or other article will be approximately on the same plane. The
shank A and hand grasping portions B are connected together, by a curved
portion which forms part of the shank of the handle or carrier, and also serves to
bring the said portions 6 and e in substantially parallel relation with each other.
The curved connection f is preferably made from the forward or largest end of the
shank A, see Figs. 1, 4, and 5, but it may be made from any other part thereof.
Figs. 1 and 3 the portion e of the stock may either be tanged shaped to provide for
it being driven into the handle proper B, or it may be constructed in socket form to
receive a handle B partly within it as at Fig. 4, or of a knife handle form as at
Fig. 5, or the handle proper may be cast or otherwise formed and constructed
complete with the tool holding socket and shank A. The curved portions A, f, e
of the shank may be prolonged so as to rest upon the file, tool, or other article C,
as shown at Figs. 1, 4, and 5, a recess 9 being provided between the tool holding
socket and the portion that rests upon the file C. By means of the recess g and
allowing the shank portion to rest upon the top of the file provision is made for
more securely and rigidly holding the file in position than when the tang d is only
inserted in the socket b. Or for the same purpose the socket may be prolonged
as shown at Fig. 3. The hole in the socket may extend the whole length thereof,
or only partly through it, but it is preferred to make it pass entirely through it for
more conveniently removing or extracting the plug.
In some cases the improved handle or carrier may be constructed as shown at
Fig. 6. (which is a part sectional elevation) so that one or more sockets b (provided
with a plug or filling of wood or other material) is or are made to slide on a

page_text: suitable bar a. The bar a is made of sufficient length to enclose the file, tool, or
other article C between the sockets b, or between the socket b and a suitable stop b¹
is then prolonged at one or both ends to allow of the attachment of one or more
handles B for the use of two persons, say for instance in filing a key seat in the hub
of a large wheel.
A handle or carrier taking the device as a whole thus constructed and applied to
a file gives a better command over the file in surfacing and permits a longer stroke
than is practicable with an ordinary handle applied thereto, and whose centre is a
prolongation of the centre line of file and by means of the socket portion of the
handle stock and its plug or filling c every facility is afforded for securing the tang
firmly therein.
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;
1st. A handle or carrier for files, tools, or other articles substantially as herein
described, consisting of a tubular socket provided with a filling or plug of wood or
other suitable substance in which is cut a longitudinal groove for the reception of
the tang of the file or other article, and a shank handle projecting from said socket
either over and parallel with the said socket or in rear thereof, the front part of the
said shank handle being recessed and arranged to rest upon the upper surface of
the file or other article as set forth.
2nd. In a handle or carrier for files, tools, or other articles substantially as
described the combination of the socket provided with a filling or plug of wood
or other material c for the reception of the tang d with a shank A, f, e arranged to
project from and to rest upon the upper surface of the file or other article in front
of the said socket as shown, all substantially as herein described and illustrated.
3rd. In a handle or carrier for files, tools, or other articles substantially as
herein described, the combination of the sockets one or both which is or are
provided with a plug or filling c of wood or other suitable material capable of
sliding and being adjusted on a bar a armed with handles B substantially as
described and illustrated at Fig. 6.
