United States of America, but at present of Sheffield, in the County
of York, Augustus Edward Stayner, of Halifax, Nova Scotia, in
the Dominion of Canada, at present of Sheffield, aforesaid, and
Jonathan Harrison, of Eastwood, in the County of Nottingham,
for the Invention of "IMPROVEMENTS IN PICKS, HAMMERS, AXES, ADZES,
AND SIMILAR TOOLS."
PROVISIONAL SPECIFICATION left by the said Charles Atwood Hardy,
Augustus Edward Stayner, and Jonathan Harrison at the Office of
the Commissioners of Patents, with their Petition, on the 22nd
September 1871.
We, CHARLES ATWOOD HARDY, of Philadelphia, in the United States
of America, but at present of Sheffield, in the County of York, AUGUSTUS
EDWARD STAYNER, of Halifax, Nova Scotia, in the Dominion of Canada,
at present of Sheffield aforesaid, and JONATHAN HARRISON, of Eastwood,
in the County of Nottingham, do hereby declare the nature of the said

page_text: Invention for "IMPROVEMENTS IN PICKS, HAMMERS, AXES, ADZES, AND SIMILAR
TOOLS," to be as follows:-
The object of this Invention is to provide miners and others with a
pick or other tool easily secured to or detached from its shaft, whose eye
or centre need not form such a protuberance as is usual, and by its
reduced size shall not so weaken the blade.
To attach the tools to their shafts or handles we employ metallic
mortises and tenons. A metallic socket of suitable form to cover and
protect the ends of the shafts or handles is provided with a projection or
tenon fitted to enter a mortise formed in the tool for which it is designed. ]
The tenon and mortise can be readily attached and detached, and be
firmly held in position when desired. The socket protects the shaft or
handle from abrasion as well as from the pinching and crushing effect to
which the eye of the ordinary pick subjects its handle.
A pin, screw, wedge, or key may be employed to hold the tenon and 1
mortise firmly together, and the tenon may if preferred be formed with
an overhanging lip, or any other suitable device may be employed to
hold it securely in its mortise.
Instead of forming the mortice in the tool it may be formed in the
socket, and the tenon formed upon the tool, although the former method 2

TO ALL TO WHOM THESE PRESENTS SHALL COME, we, CHARLES
ATWOOD HARDY, of Philadelphia, in the United States of America, but
at present of Sheffield, in the County of York, AUGUSTUS EDWARD
STAYNER, of Halifax, Nova Scotia, in the Dominion of Canada, at
present of Sheffield aforesaid, and JONATHAN HARRISON, of Eastwood,

WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-second day of September, in the

page_text: year of our Lord One thousand eight hundred and seventy-one, in the
thirty-fifth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Charles Atwood Hardy, Augustus
Edward Stayner, and Jonathan Harrison, Her special licence that we,
6 the Charles Atwood Hardy, Augustus Edward Stayner, and Jonathan
Harrison, our executors, administrators, and assigns, or such others as
we, the said Charles Atwood Hardy, Augustus Edward Stayner, and
Jonathan Harrison, our executors, administrators, and assigns, should
at any time agree with, and no others, from time to time and at all
times thereafter during the term therein expressed, should and lawfully
might make, use, exercise, and vend, within the United Kingdom of
Great Britain and Ireland, the Channel Islands, and Isle of Man, an
Invention for "IMPROVEMENTS IN PICKS, HAMMERS, AXES, ADZES, AND SIMILAR
TOOLS," upon the condition (amongst others) that we, the said Charles
5 Atwood Hardy, Augustus Edward Stayner, and Jonathan Harrison, our
executors or administrators, by an instrument in writing under our, or
their, or one of their hands and seals, should particularly describe and
ascertain the nature of the said Invention, and in what manner the
same was to be performed, and cause the same to be filed in the
Great Seal Patent Office within six calendar months next and imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Charles Atwood Hardy, on behalf of
myself and the said Augustus Edward Stayner and Jonathan Harrison,
do hereby declare the nature of our said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained
in and by the following statement thereof, that is to say:-
The object of this Invention is to provide miners and others with a
pick or other tool easily secured to or detached from its shaft, whose eye
or centre need not form such a protuberance as is usual, and by its
reduced size shall not so weaken the blade.
To attach the tools to their shafts or handles we employ metallic
mortises and tenons. A metallic socket of suitable form to cover and
protect the ends of the shafts or handles is provided with a projection or
tenon fitted to enter a mortise formed in the tool for which it is designed.
The tenon and mortise can be readily attached and detached, and be
firmly held in position when desired. The socket protects the shaft or

page_text: applicable to connecting hammers, axes, adzes, and similar tools to their
shafts or handles, as will be well understood.
We do not limit ourselves to the use of any particular shape or size
of mortice and tenon for securing picks and other similar tools to their
shafts or handles.
By the means herein-before described the tool is easily connected and
disconnected from its shaft or handle, and yet when in use they are
firmly attached together, whilst great strength, durability, and portability
are obtained, as one shaft or handle with its head and tenon will serve
for a number of different sizes or descriptions of blades or of different
tools.
If desired, instead of forming the tenon upon the head or socket of
the shaft or handle it may be formed on the tool, and the mortice may
be formed in the head or socket, as will be well understood.
Having thus described the nature of our said Invention, and the mode
in which we carry the same into effect, we would have it understood
that what we claim is, the employment of metallic tenons and mortices
to connect together picks and other similar tools with their shafts or
handles, in manner substantially as herein shown and described.
In witness whereof, I, the said Charles Atwood Hardy, have here-
unto set my hand and seal, this Nineteenth day of March in the
year of our Lord One thousand eight hundred and seventy-two.
CHARLES ATWOOD HARDY. (L.S.).
