page_text: LETTERS PATENT to John Henry Johnson, of 47, Lincoln's Inn
Fields, in the County of Middlesex, Gentleman, for the Invention of
"IMPROVEMENTS IN SAW HANDLES, AND IN SECURING THE SAME TO SAW
BLADES." A communication from abroad by Charles White Hubbard,
of Pittsburgh, in the County of Allegheny, State of Pennsylvania,
United States of America.
Sealed the 6th April 1869, and dated the 8th October 1868.
PROVISIONAL SPECIFICATION left by the said John Henry Johnson
at the Office of the Commissioners of Patents, with his Petition, on.
the 8th October 1868.
I, JOHN HENRY JOHNSON, of 47, Lincoln's Inn Fields, in the County
of Middlesex, Gentleman, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN SAW HANDLES, AND IN SECURING THE SAME TO
SAW BLADES," & communication from abroad by Charles White Hubbard,
of Pittsburgh, in the County of Allegheny, State of Pennsylvania, United
States of America, to be as follows:-
This Invention consists in making a saw blade with a slot in the rear
end, which slot in form and size corresponds to the form and size of a

page_text: bolt carried in the handle, one end of which bolt is provided with screw
threads, to which is fitted a screw nut placed in a recess made in the saw
handle. The back end of the saw blade is fitted into a groove made in
the front end of the handle. The part of the handle which is grasped by
the hand of the operator is formed of wood, and is secured to the metal part
by means of screws or rivets. When applying the handle to the blade
the bolt is turned so that its head will be in such a position as to enter
the slot in the saw blade, the back end of which blade is placed in a
groove in the metal part of the handle. The bolt is then turned so that
its head will be locked in the slot, and the nut is turned by any suitable
means until it and the bolt has drawn the handle and saw blade firmly
and securely together.
It is obvious that the improved saw handle may be made of metal or
wood or of metal and wood combined.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Henry Johnson in the Great Seal Patent
Office on the 7th April 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
HENRY JOHNSON, of 47, Lincoln's Inn Fields, in the County of Mid-
dlesex, Gentleman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighth day of October, in the year
of our Lord One thousand eight hundred and sixty-eight, in the thirty-
second year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said John Henry Johnson, Her special
license that I, the said John Henry Johnson, my executors, adminis-
trators, and assigns, or such others as I, the said John Henry Johnson,
my executors, administrators, or assigns, should at any time agrec
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 SAW HANDLES, AND IN SECURING THE SAME TO SAW BLADES,”
a communication from abroad by Charles White Hubbard, of Pittsburgh,
in the County of Allegheny, State of Pennyslvania, United States of

page_text: America, upon the condition (amongst others) that I, the said John
Henry Johnson, my executors or administrators, by an instrument in
writing under my hand and seal, should particularly describe and ascer-
tain 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 immediately after the date
of the said Letters Patent.
NOW KNOW YE, that I, the said John Henry Johnson, do hereby
declare the nature of the said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in
and by the following statement, reference being had to the accom-
panying Drawings, and to the letters and figures marked thereon, that is
to say :-
This Invention consists in improvements in saw handles, and in the
method herein-after described for securing handles to the blades
of saws.
In the accompanying Drawings, which form part of this Specification,
Figure 1 is a side elevation shewing the improvement in saw handles,
and represents also the manner of securing the same to the saw blade;
Figure 2 is a side elevation, partly in section, of the metal part of the
handle detached, representing the arrangement of the bolt and its screw
nut in the handle.
g represents a portion of an ordinary saw blade furnished with a slot A
which in form and size corresponds to the form and size of the bolt B,
one end of which is provided with screw threads o, to which is fitted a
screw nut C, which is placed in a recess f made in the part i of the
handle J. The back end of the saw blade g is fitted into a groove
made in the front end of the handle J, as indicated by the dotted lines
marked e. The part D of the handle which is grasped by the hand of
the operator is formed of wood, and is secured to the metal part J by
means of screws or rivets h.
As the construction and arrangement of the improved saw handle
will be readily understood by the skilful mechanic by reference to the
accompanying Drawings, I will therefore without further description of
its construction proceed to describe its operation, which is as follows:-
The bolt B is turned so that its head X will be in the position represented
in Figure 2; the bolt B is then placed in the slot A of the saw blade g,
the back end of which is placed in the groove indicated by the dotted

page_text: line e.
The bolt B is then turned so that its head X will be in the
position represented in Figure 1, when the nut C is turned by any suitable
means until it and the bolt B have drawn the handle J and saw blade g
firmly and securely together.
It will be readily observed that the improved saw handle may be made
of metal or wood, or of metal and wood combined, and may be secured to
the saw blade substantially in the manner and by the means herein
described, therefore I wish it clearly understood that I do not confine
myself to any one form or arrangement of the several parts described,
since the form and arrangement may be varied and like result be
obtained.
Having now described and particularly ascertained the nature of the
said Invention, 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,---
First. The combination of the slot A and bolt B for securing a handle
to the blade of a hand saw substantially as herein-before described and
set forth.
Second. The construction and use of a handle for a hand saw, con-
structed and arranged substantially as herein-before described and for
the purpose set forth.
In witness whereof, I, the said John Henry Johnson, have to this
my Specification set my hand and seal, the Seventh day of April,
One thousand eight hundred and sixty-nine.
