to make, use, exercise, and vend, within that part of the Kingdom of Great
Britain called England, the Dominion of Wales, and Town of Berwick-upon-
Tweed, for the space fourteen years from the date thereof, a certain Invention
called the "UNIVERSAL MACHINE LINES FOR WRITING OR DRAWING," provided
that the said Joseph Fisher should particularly describe and ascertain the
said Invention, and cause such description thereof to be inrolled in High
Court of Chancery within four months from the date of the said Letters
Patent.
NOW, IN PURSUANCE of and conformity to the said Letters Patent, the
said Joseph Fisher doth exhibit the following Figure and description of the
said Invention and machine, and declare the same to be and contain a true
and particular description thereof, and the manner in which the same is to
be performed, and Specification for making of the same, viz*:-
A, B, C, are thre rulers which are made to move parallel by means of
four pieces which move on six centers marked 1, 2, 3, 4, 5, 6; these four
pieces are marked D, E, F, G. The lines, which are made of fine thin silk,
are fixed to the joints marked H, I, which are fastned to the ends of the
2 rulers A & C; the knob marked K is fixt to a plate of brass which is
pin'd to the end of the rular A, and slides in a grove at the end of the frame

page_text: marked L, and by moving the knob K to L, and from L to K, all the lines
extend or contract in a parallel direction, and at equal distances. In inferior
instruments the lines are fixt to the four pieces D, E, F, G, without the joints
H, I, and move in the same direction. A board or plate covered with white
paper is fixt between the rulers and lines, over which is placed the paper
for writing on. The geometrical squares for drawing are made to extend or
contract by placing four pieces of machinery made to move with joints like
H; I, one at each side of a square frame or drawing board; to these joints
the lines are fixt, and these are moved by sliding the knob, as is above
described a K.
In testimony whereof, the said Joseph Fisher hath hereunto set his
hand and seal, the Seventh day of October, in the year of our Lord

to all the lines extend or contract in a parallel direction and at equal distances
In inferior instruments the lines are fixt to the four pieces DEFG without the
joints III. and move in the same direction. A board or plate cover with white

on. The Geometrical squares for Drawing are made to Extend or Contract by placing
four pieces of Machinery made to move with Joints like III. One at each side of a
square frame or Drawing board to these joints the Lines are fixed and these are
moved by sliding the lanob as is above described, at K
