Improvements in Handles Adapted to Receive Files, Rasps, Saws, and
other Hand Tools of a similar kind.
We ALFRED ROWE BELLAMY of Algoa Lodge, Stockport, in the County
of Chester, Engineer, and ALBERT JOHN HOBSON of Suffolk Works, Sheffield,
in the County of York, Cutlery Manufacturer, do hereby declare the nature of
this invention to be as follows.
My said invention relates to an improved handle formed in such a manner that
files, rasps, saws and similar hand tools can be readily connected to and removed
from such handles. We split the handle or form it with a saw-gate or slit of
sufficient length and of width enough to admit the shank of the file or other
tool. Across this slit and a suitable distance apart, we place fixed rivets or
stops and form the handle at the slit or sawn end to receive a ring or ferrule
which when applied or slipped on tends to draw the split or sawn halves of the
handle together. The shank of the file or other tool intended to occupy the
handle has a vee nick at the end, and a similar nick in the side, the pitch of
the nicks when bottomed being the same or about the same as the distance apart
of the aforesaid fixed rivets or stops. When applying the file or tool to the
handle we insert the picked end of the shank into the gate in the handle and
over the furthest back, fixed rivet or stop. Using this as a pivot we then fold
the tool down, till its side nick rides upon the second fixed rivet or stop. The file
or tool now lies parallel to the handle and to fix it in position it is only
necessary to push the ring or ferrule upon the end of the handle thereby drawing
the halves of the handle together and firmly binding as well as imprisoning the
shank in the handle. To release the file, a tap will remove the ring and the
file shank may then be taken out of the handle. Tools may thus be removed
from or connected to their handles without any knocking, or removal of rivets or
other inconveniences. The improved handle is specially useful in hafting the
files used to sharpen the knives of reaping machines, and the ring or ferrule which
binds the handle and file together may be made large enough to act as a hilt or
guard to protect the user's hand from possible contact with the edge of the knife
being sharpened or of the adjacent knives.

We ALFRED ROWE BELLAMY of Algoa Lodge, Stockport, in the County

:-
Our said invention relates to an improved handle made in such a manner that
files, rasps, saws and similar hand tools formed with a flat extension or tong can
be readily placed in and removed from such handles.
The improved handle is however particularly useful in the case of files employed
to sharpen the blades of reaping machines, as the hafting and unhafting of the
files can be done in the open field without any knocking or removal of rivets or
the like.
The improved bandle will be best understood from a reference to the annexed
sheet of drawings.
Fig. 1 is a side view of the handle as it appears when the file is fixed in
position.
Fig. 2 is a plan of Fig. 1.
Fig. 3 is a separate view of the tail or shank of the file showing the notches by
which it is held in position.
Fig. 4 illustrates the mode of introducing the tail or shank of the file into the
handle.
Fig. 5 is an end view of the curb ring or ferrule which holds the file and handle
together.
Fig. 6 is a longitudinal sectional view of the handle with the file in position.
The handle a is made with a sawgate or slit a' at one end and is reduced at a²
(see Fig. 4) so as to receive the ferrule b which can be easily slipped on and off
the reduced portion a². Through the handle and extending across the slit a¹ we
fix two rivets or stops cc which both strengthen the slit portion of the handle and
also serve as holdfasts to retain the file. The file d has a shank d¹ as shown in
Fig. 3 and in the end of the shank we form a notch d2 while in the lower edge of
the shank we form a second notch d³ the centres of the said notches corresponding
to the centres of the rivets c c¹.
When attaching the file to the handle, we remove the ferrule 6 from the handle
and slip
upon the file shank. The notch d in the end of the file shank d' is
then placed over the rivet e as shown in Fig. 4 and the file is then turned down
until the notch d³ fits over the rivet c' and the file lies in line with the handle.
The ferrule is then slipped over the reduced end a² of the handle so that the parts
are firmly bound together as shown in Fig. 6. The file caunot possibly be
disengaged from the handle without slipping off the ferrule. The outward spring
of the slit portion of the hamlle serves to hold the ferrule in position and prevents
it from becoming loose. A slight tap will remove the ferrule and enable the file
to be released.
Although we have throughout this description spoken of the tool as a file, it
will be evident that any other hand tool of a similar nature, such for example as a
rasp or saw could be similarly bafted. We however consider the handle as specially
suitable for hatting the flat files employed to sharpen the knives of reaping
machines in the field, as the handle can be removed from the file without knocking
and without the removal of rivets or the like. The ring or ferrule might
made large enough to act as a hilt or guard to protect the user's hand from possible
contact with the edge of the knife being sharpened or the edges of the adjacent
knives.
Having now particularly described and ascertained the nature of our said inven
tion and in what manner the same is to be performed we declare that what we
claim is.
1. The handle a for hafting reapers files and similar hand tools and having a
slit o' to receive the shank of the tool, rivets or stops ce¹ extending across the slit
and a ferrule fitting upon the reduced slit end of the handle, substantially as
described and show u

page_text: 2. The slit handle a with rivets cc' and ferrule bin combination with the notched
file or tool shank d substantially as described and shown.
