SINGLETON, of Featherstone Street, in the Parish of Saint Luke, in the County
of Middlesex, Callico Glazier, send greeting.
WHEREAS the King's most Excellent Majesty, by His Letters
Patent under the Great Seal of Great Britain, bearing date at Westminster,
the Sixth day of November last past, after reciting that I, the said George
Singleton, had, by my Petition, represented that the business of glazing of
linnens, cottons, callicoes, muslins, stuffs of linnen and cotton buckrams, and
various other articles of British manufacture, as well of those of India, had
been performed by hard manual labour, with great expence, and much inferior
to those done in other countries; and that in order to render the business of
glazing the same and all other commodities that are commonly glazed more
easy, more expeditious, and less expensive, I, the said George Singleton,
had found out and invented "SoиE ALTERATIONS, IMPROVEMENTS, AND ADDITIONS
IN, ABOUT, AND TO THE OLD MACHINE THEREIN DESCRIBED;" and I, the said-
George Singleton, prayed that our said Sovereign Lord the King would grant
unto me, my executors, administrators, and assigns, His Royal Letters Paterit,
under the said Great Seal, for the sole use, benefit, and advantage of my said
Invention, within the places and for the term therein mentioned: it is by the
said Letters Patent granted that our said Sovereign Lord the King did give
and grant unto me, the said George Singleton, my executors, administrators,
and assigns, special licence, full power, privilege and authority, that I, the said

should and lawfully might make, exercise, and vend my said Invention within
the places and for the term therein limited; in which said Letters Patent is
contained a proviso that if I, the said George Singleton, should not particularly
describe and ascertain the nature of my said Invention, and in what manner
the same is to be performed, by an instrument in writing under my hand and
seal, and cause the same to be inrolled in the High Court of Chancery within
one callendar month next and immediately after the date of the said Letters
Patent, that then that such Letters Patent and all liberties and advantages
whatsoever thereby granted should utterly cease, determine, and become void,
as in and by the said Letters Patent, referrence being thereunto had, will more
fully and at large.appear.
NOW KNOW YE, that I, the said George Singleton, in pursuance of and in
compliance with the said provisoe in the said recited Royal Letters Patent, do
by this present Instrument declare that the nature of my said new Invention,
alterations, improvements, and additions, and the manner in which the same are
to be performed, is described and explained in the Plan or Drawing thereof here-
unto annexed; but in which said Plan or Drawing is comprehended the machine
formerly used, save as to a twisted rope which is omitted in such Plan, and
substituted by a weight fastened to the loose end of a spring herein-after men-
tioned, marked D, and in which is explained and referred to in the letters,
words, and figures following, that is to say, viz. :-
A, a deal plank; fixed to the ceiling; B, a raking brace, one end fixed
to the plank, the other end to the floor; C, an ash spring fixed to, a
plank A; D, a weight fastened to the loose end of the spring C, men-
tioned above, to be substituted in the lieu of the twisted rope used in the
old machine; E, a block of wood with a socket; F, an upright polo which
goes into the socket of block E, which is kept on the spring C by means
of a cord, and on the lower end of which pole is a piece of wood which
contains a glazing flint which is rounded ou each end; H, a table; I, a
glazing block fixed to the table H, all of which relates to the machine
formerly used, save and except as to the weight above mentioned, and which
comprehends part of my said Invention and improvement.
And I, the said George Singleton, do further declare, that the several
alterations, improvements, and additions mentioned and contained in the said s
Plan or Drawing thereof are of any invention, and are described and explained
therein, together with the manner in which the same are to be performed,
that is to say-
G, a raking brace fixed to the loose end of the spring C, and fastened by

page_text: means of a pin to lever Q, herein-after mentioned; K, K, two groves in which
a frame runs; L, a frame which runs ontrollers in the groves K, K, which
frame is further illustrated by Figure 2 and 3; M, a piece of wood which
slips on the pole F, through the neck of which piece of wood is fixed to said
pole F by an iron pin, and rests on a small brackett and strikes the top of the
spring O, which relieves the click from the rack b, which gives the weights
fastened to the cords f liberty to act and draw the frame L the space of one
inch, when it is again stopt by the click; N, two pieces of wood fastened "to
the brace B, which forms a groove for the upright pole F, which steadies it in
working; O, an upright wood spring fixed to the table II, in which is a
projecting iron which serves as a click by stopping the frame L, by means of
the rack fixed on the upper part of the frame; P, a small line fixed to the
spring O, which, passing through a pulley fixed to brace B, comes underneath
the groove N, and serves the person attending the work to relieve the frame
when necessary; Q, a lever, the short end of which being fixed by means of a
pin to the raking brace G, the fulcrum being fastened to the floor at about one
foot distance from the end (and coming under the table for the convenience of
the workmen), which by being pressed down raises the spring, by which means
the flint is disengaged from the cloth, in case of holes, to chalk the block, or
any other cause; R, a treadle, fastened to the long end of the lever Q, for the
convenience of raising the flint a small space from the cloth; S, S, two sliding
stops fixed to the frame of the table 1, 'to keep the lever Q in different
stations; T, T, two stantions, fixed strong, to hold the winch W; U, an axis
with a crank fifteen inches in length, which is turned by a winch; V, a wheel
or fly; W, an horizontal pole, fixed at one end to the crank U, and is fastened
by a pin through a neck to the vertical pole F, and gives motion to the
machine.
Figure 2 represents the plan of the frame L. a, the upper roller on which
the cloth to be glazed is fixed in a hole at one end, the other end slips into a
groove in the frame, at which end there is a racket wheel, which is stopped by
a small steel ketch, and by that means keeps the cloth tight; b, the other roler,
which is fixed in same manner to the lower end of the frame as roler a, and
serves to wind the cloth off the roler as it is glazed; c, an iron rack fitted on the
upper part of the frame, whose teeth are one inch or more apart, which teeth
catch in the click on the spring 0; d, d, two rails, which the cloth goes over;
e, an iron spring which slips into the ratchet wheel on roler a; f, two lines,
which passing on pulleys fixt on the supports to the grooves k, k, to which are
suspended weights sufficiently heavy to draw the frame when relieved from the
click in spring O; g, a small ketch to keep the roler 6 from moving.
