Year: 1873

page_text: LETTERS PATENT to John Saunders, of Cirencester, Gloucestershire,
for the Invention of "IMPROVEMENTS IN APPARATUS FOR THE MANU-
FACTURE OR PICTURE FRAMES. APPLICABLE ALSO TO OTHER PURPOSES."
Sealed the 5th June 1874, and dated the 15th December 1873.
PROVISIONAL SPECIFICATION left by the said John Saunders at the
Office of the Commissioners of Patents, with his Petition, on the
15th December 1873.
I, JOHN SAUNDERS, of Cirencester, Gloucestershire, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN APPARATUS FOR THE
MANUFACTURE OF PICTURE FRAMES, APPLICABLE ALSO TO OTHER PURPOSES," to
be as follows:-
The object of this Invention is to " cramp" picture frames and other
like articles, whether square, round, oval, triangular, or of whatever
shape they may be, while the joints are permanently screwed, bradded,
or fastened together.
The apparatus consists of a drum carried upon an axle mounted in
suitable framework, said drum carrying a gut or other sufficiently

page_text: strong cord, which is passed over sheaves mounted in blocks formed to
fit the angles of the article to be cramped.
A winch handle and ratchet wheel is mounted upon the drum axle, and
a catch pivoted to one of the end pieces of the framework gears with
said ratchet wheel, and direction pulleys are mounted in the framework
below the drum, over which pulleys the cord is carried from the angle
blocks to the drum. Openings are provided in the angle blocks for
driving the brads or screws.
In employing this apparatus the angle block and cord or cords are
adjusted, and by the action of the winch handle the cord is wound upon
the drum until sufficiently tightened to "cramp" the work, the catch in
gear with the ratchet wheel holding the drum forward and keeping the
cord at the required tension.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Saunders in the Great Seal Patent Office
on the 15th June 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
SAUNDERS, of Cirencester, Gloucestershire, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifteenth day of December, in the
year of our Lord One thousand eight hundred and seventy-three, in the
thirty-seventh year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said John Saunders, Her special
licence that I, the said John Saunders, my executors, administrators,
and assigns, or such others as I, the said John Saunders, my 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, andv end,
within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN APPARATUS
FOR THE MANUFACTURE OF PICTURE FRAMES, APPLICABLE ALSO TO OTHER PURPOSES,"
upon the condition (amongst others) that I the said John Saunders, my
executors or administrators, by an instrument in writing under my, or
their, or one of their hands and seals, should particularly describe and

page_text: 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 John Saunders, 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 accompanying Sheet
of Drawings, and to the figures and letters of reference marked thereon,
that is to say :-
The object of this Invention is to cramp picture frames and other like
articles, whether square, round, oval, triangular, or of whatever shape
they may be, while the joints are permanently screwed, bradded, or
fastened together.
In order that my Invention may be clearly understood, I have here-
unto annexed a Sheet of Drawings illustrative thereof, in which Fig. 1 is
a plan view of the apparatus applied to the cramping of a square picture
frame (part only of the frame being shown); Fig. 2 is a side view;
Fig. 3, an end view; and Fig. 4, an elevation of the angle block.
The apparatus consists of a drum carried upon an axle A mounted in
suitable framework B, said drum carrying a gut or other sufficiently
strong cord C, which is passed over sheaves D mounted in blocks formed
to fit the angles of the article to be cramped.
A winch handle and ratchet wheel E is mounted upon the drum axle,
and a catch F pivoted to one of the end pieces of the framework gears
with said ratchet wheel; and direction pulleys G are mounted in the
framework below the drum, over which pulleys the cord C is carried
from the angle blocks D¹ to the drum. Openings H, Fig. 4, are
provided in the angle blocks for driving the brads or screws into the
frame I.
In employing this apparatus the angle block and cord or cords are
adjusted, and by the action of the winch handle the cord is wound upon
the drum until sufficiently tightened to "cramp" the work, the catch F
in gear with the ratchet wheel holding the drum forward and keeping
the cord at the required tension.
Having now described the nature and particulars of my said Invention,
I claim the improved apparatus for cramping picture frames and other

page_text: like articles, substantially as herein described and shown on the
Drawings.
In witness whereof, I, the said John Saunders, have hereunto set
my hand and seal, this Tenth day of June One thousand eight
hundred and seventy-four.
