Year: 1878

page_text: LETTERS PATENT to William Gray, of Sheffield, in the County of York, File
Manufacturer, for the Invention of "IMPROVEMENTS IN FILES, AND IN HAFTS
OR HOLDERS FOR THE SAME."
Sealed the 28th January 1879, and dated the 30th October 1878.
.
PROVISIONAL SPECIFICATION left by the said William Gray at the Office
of the Commissioners of Patents on the 30th October 1878.
WILLIAM GRAY, of Sheffield, in the County of York, File Manufacturer.
PROVEMENTS IN FILES, AND IN HAFTS OR HOLDERS FOR THE SAME."
"IM-
My Invention relates to improvements in files, and in hafts or holders for the
same, whereby their cost is reduced, and they are rendered more convenient for
carrying about by the workmen employed in using them, and it consists in con-
structing the files without tangs, and in the employment of hafts or holders, each
having a socket or recess corresponding in shape to the section of the file to be used
therewith, and into which the end of the file is inserted. The file may be secured
in the socket or recess in the haft or holder, either by means of a screw passing
through a hole in the metal or material forming the sides of the recess, and through
a hole in the file, or by wedging the file in the socket or recess, or in any other
convenient manner.
My Invention, which is intended more particularly to be applied to files for
sharpening the knives of reaping machines, is applicable to files of a knife three-
square, round, half round, or flat shape, or of any other desired section.
When a screw is employed for securing the file to its haft or holder one of the
corners of that end of the file which is inserted in the socket or recess may be
truncated or removed so as to enable the end of a loose file to be used as a screw-
driver when an ordinary screwdriver is not readily obtainable.

"IM-
My said Invention relates to improvements in files, and in hafts or holders for
the same, whereby their cost is reduced, and they are rendered more convenient for
carrying about by the workmen employed in using them, and it consists in con-
structing the files without tangs, and in the employment of hafts or holders, each
having a socket or recess corresponding or approximating in shape to the section of
the file to be used therewith, and into which the end of the file is inserted. The
file may be secured in the socket or recess in the haft or holder either by means of
a screw passing through a hole in the metal or material forming the sides of the
récess, and through a hole in the file, or by wedging the file in the socket or recess,
or in any other convenient manner.
My said Invention, which is intended more particularly to be applied to files for
sharpening the knives of reaping machines, is applicable to files of any required
section, as for instance, of a knife, three-square, round, half round, or flat shape,
examples of which are given in the Sheet of Drawings hereunto annexed.
Figure 1 of the accompanying Drawings represents a perspective view of a file
of a knife shape with haft or handle complete constructed according to my said
Invention; Figure 2 represents perspective views of the file and its haft or handle
detached; Figures 3, 4, 5, and 6 are similar views to Figure 2, illustrating the
application of my said Invention to files of a three-square, round, half round, and
flat shape respectively..
A is the file, which is constructed without a tang, it being of similar section
throughout, and B is the haft or holder, having a socket or recess a corresponding
in shape to the section of the file to be used therewith, and into which the end of
the file is inserted, as shewn in Figure 1. The extremity of the file is perforated
at b, and a tapped hole is provided in the haft or handle for the reception of a
screw pin c, which passes through the haft or handle and the hole b in the file, thus
securing the file in the socket or recess a; or in lieu of this method of fixing it the
file may be secured in the socket or recess by wedging, or in any other convenient
manner.
"
When a screw is employed for securing the file to its haft or holder, as in the
examples illustrated, one of the corners of that end of the file which is insorted in
the socket or recess may be truncated or removed, as shewn at d in Figure 2, so as
to enable the end of a loose file to be used as a screwdriver when an ordinary screw-
driver is not readily obtainable.
Files constructed according to my said Invention are designated "tangless files
for sharpening reaping machine knives and for other purposes."
Having now described and particularly ascertained the nature of my said Inven-
tion, and the manner in which the same is or may be used or carried into effect, I
would observe in conclusion that what I consider to be novel and original, and
therefore claim as the Invention secured to me by the herein-before in part recited
Letters Patent is,―
The employment of tangless files in combination with hafts or holders, each
having a socket or recess for the reception of the end of the file of a section corre-

page_text: sponding or approximating to the shape of the file to be secured therein, substan-
tially as herein-before described.
In witness whereof, I, the said William Gray, have to this my Specification
set my hand and seal, the Seventeenth day of February, One thousand
eight hundred and seventy-nine.
