page_text: I, GEORGE CONWAY, of Marnbull, in the County of Dorset, Saddler and Harness
Maker, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in saddlers' and shoe makers' awls,
and in accordance therewith I form as an integral part of the handle of the awl,
or fix thereto a screw-threaded nose having a square recess or counter-sinking
in its forward end.
Upon this said screw-threaded nose fits a chuck or blade holder, which tapers
toward the forward end and is of hollow construction, the interior being tapped
so as to allow such chuck or blade holder to screw upon the nose aforesaid.
The interchangeable blades of the awl are formed with squared and shouldered
butts which fit within the square recess in the end of the screw-threaded nose
aforesaid, the forward end of the blade projecting through an open-
ing in the forward end of the removable chuck or blade holder.
When it is desired to fit a blade to the awl handle, the chuck or blade holder
is unscrewed from the nose of the former and the desired class of blade fitted
in the said chuck or blade holder, which latter is then screwed upon the nose of
the awl handle, causing the squared rear end of the blade to fit snugly within
the recess in the forward end of the nose and be held securely in position.
A portion of the outer periphery of the removable chuck or blade holder
aforesaid is milled in order to facilitate the turning of such chuck or blade
holder.

I, GEORGE CONWAY, of Marnbull, in the County of Dorset, Saddler and Harness
Maker, 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 relates to improvements in saddler's and shoemaker's awls,
and consists in providing means for readily interchanging the blades of such awls
and holding them firmly in the handles."
In accordance with my said invention I form as an integral part of the handle
of the awl, or fix thereto, a screw-threaded nose having a square recess or counter-
sinking in its forward end.

page_text: Upon this said screw-threaded nose fits a chuck or blade holder, which tapers
toward the forward end and is of hollow construction, the interior being tapped
so as to allow such chuck or blade holder to screw upon the nose aforesaid.
The interchangeable blades of the awl are formed with squared and shouldered
butts which fit within the square recess in the end of the screw-threaded nose
aforesaid, the forward end of the blade projecting through the open-
ing in the forward end of the removable chuck or blade holder.
When it is desired to fit a blade to the awl handle, the chuck or blade holder
is unscrewed from the nose of the former and the desired class of blade fitted
in the said chuck or blade holder, which latter is then screwed upon the nose of
the awl handle, causing the square rear end of the blade to fit snugly within
the recess in the forward end of the nose and be held securely in position.
A portion of the outer periphery of the removable chuck or blade holder
aforesaid is milled in order to facilitate the turning of such chuck or blade
holder.
In order that this my said invention may be the more readily understood and
carried into practical effect, reference is hereby made to the accompanying sheet
of illustrative drawings, wherein :
Fig. 1 is an elevational view of a complete awl fashioned in accordance with
my invention, Fig. 2 being a view partly in section thereof. Fig. 3 is a perspec-
tive view of one of the awl blades which forms part of the invention, while Fig. 4
is a view, partly in section, shewing the chuck or blade holder with a blade in
position therein ready for screwing on to the awl handle.
Referring to the drawings, wherein like letters of reference indicate corre-
sponding parts wherever occurring throughout the several figures, a represents
the awl handle, formed with a screw-threaded nose a¹ having a counter-sink-
ing a in its forward extremity. b represents the tapered hollow chuck or blade
holder, the tapered portion of which is tapped or interiorally screw-threaded in
order to allow such chuck or blade holder to have a screw connection with the
nose a of the awl handle a.
The extremity b' of the chuck or blade holder 6 is flanged around the opening
therein, in order to form a ledge for the rear end of the blade to rest upon and
prevent the withdrawal of such blade, the opening in the said extremity of the
chuck or blade holder being of such a size as to permit only the narrow portion
of the blade to pass through same.
The blades c, of which there may be any suitable number and variety are
formed with square butts c and shoulders 2, the forward or diminished parts of
the blade so formed projecting through the opening in the extremity of the
chuck or blade holder, when the blade is fitted into position.
To fit a blade to the awl handle, the chuck or blade holder b is unscrewed from
the nose a¹ of the handle and the desired class of blade fitted in the said chuck
or blade holder. The latter is then screwed upon the nose a, causing the squared
end of the blade to fit snugly within the countersunk recess a² in the nose a¹,
and be held securely in position.
The outer periphery of the removable chuck or blade holder b is milled as at 6
in order to facilitate the turning of such chuck or blade holder.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is-
1. The improvements in saddler's and shoe-maker's awls, consisting in a handle
having a diminished screw-threaded nose with a recess in its extremity, and a
removable tapered chuck or blade holder, said chuck or blade-holder being tapped
and having its forward end inwardly flanged to diminish the end opening and
form a ledge around same and a set of blades having their rear ends enlarged
to form square butts provided with shoulders, substantially as hereinbefore des-
cribed and as illustrated.

page_text: 2. In improvements in saddler's and shoe-maker's awls, the combination with
a handle having a diminished screw-threaded nose provided with a recess in its
extremity of a removable hollow tapered chuck or blade-holder, said chuck or
blade-holder being tapped or interiorally screw-threaded and having its forward
extremity inwardly turned so as to diminish the end opening and form a ledge
around same; and interchangeable blades having enlarged rear ends to form
squared butts provided with shoulders, all substantially as and for the purpose
herein before described and as illustrated by the drawings.
Dated this 18th day of September 1900.
