Year: 1797

page_text: TO ALL TO WHOM THESE PRESENTS, SHALL COME, I, JOSEPH
SLATER, of Sharples, near Bolton-in-le-Moors, in the County of Lancaster,
Bleacher, send greeting.
WHEREAS His most Excellent Majesty King George the Third, by His
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Fourth day of July, in the thirty-seventh year of His reign, did give
and grant unto me, the said Joseph Slater, His special licence that I, the said
Joseph Slater, during the term of years therein mentioned, should and lawfully
might 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, my
Invention of "CERTAIN IMPROVEMENTS IN A MACHINE FOR THE FINISHING OF BLEACHED,
DYED, AND PRINTED MUSLINS;" in which said Letters Patent there is contained
a proviso, obliging me, the said Joseph Slater, by an instrument in writing
under my hand and seal, to cause a particular description of the nature of my
said Invention, and in what manner the same is to be performed, to be inrolled
in His Majesty's High Court of Chancery within one calendar month next
and immediately after the date of the said recited Letters Patent, as in
and by the same (relation being thereunto had) may more fully and at large
appear.

page_text: The Table is divided in four parts 1, 2, 8, 8. at the Toints over the Screws 9. 9. 9. and is level with each other and with the Inner Edge of the Clamp Boards and is supported by Two wheels at each end, which run upon the Rails marked 10.
The Distance betwixt each of the Screws, may be made 5 or 6 yards which is supported in the middle by the spring Rods marked 7 which keep the moving Clamp Bourd from being hollow in the middle betwixt the Screws .
The Screws marked a, are supported at one end in the step or point at the top of the legs marked 11 and are fixed parrallel to each other by the hails marked 12, which Rails are supported in the middle by the Legs marked 13.
The Cloath is laid upon the Table which is fastned under the Clamps at the end b, c. and the other end Hooked upon the plate A then stretched to its proper titeness for putting under the Clamps on each side by turning the Roller B
which communicates to the Plate A by two cords or bands.
which ends are
-After the Cloath is put under the Clamps on each side it is stretched to its proper width by Turning Handles 3 or 4 which turns the Screws marked it, by cog wheels put oopon the Tumbling Shaft 5 and (which works the Cog Wheels put
upon the ends of the Screws marked, d, as are e, e. e. e, which screw move the Clamp Board 14. 14. through the Nuts marked 15 and then it is ready for finishing as on the old frame. NB The Screws, marked o, d, d, d, d, which
move the Clamp Board 14. 144, may be worked several different ways by fixing the Tumbling Shaft 5, and 6, about six feet high and nearly perpendicular over that end of the screws which is supported at the top of the legs marked 11, on
Cog Wheels instead of those at e e e e e and the Cogwheels upon the Tumbling or Horizontal Shaft at e. e. e. e. e. work the perpendicular shafts which shafts work the Cogwheels at the ends of the screws at the top of the
legs marked 11. The reason for fixing the tumbling or horizontal shaft, about six feet high from the ends of the Screws (which causes the necessity of the perpendicular shafts is for the purpose of allowing room for the finishers, when workin
on that side of the frame - and likewise they may be worked with bands straps or chains by fixing pullies or drums upon each end of the screws and letting the cord, shap, band, or chain, take one or more turns round each of the said pullies or
drums and then unite the two ends together and with a Handle or Lever put upon one or more of the Screws may be worked at pleasure, or by any communication that obliges one and all the screws to make the same revolutions.
The advantages
the
new machine or frame has over the old one consist in the following particulars - First that a whole piece of any length of Cloth may be put in the sume Machine or Frame and finished at one time and by that means
does away the difficulty that attends the old one, which by reason of its short length cannot otherwise be avoided. The old one upon the same principals cannot conveniently be made more than Seven yards long which is as long as a sufficient size of
Timber for the moving Clamp boards will carry without being inclined to be circular or bowed in the middle, when the Cloth is screwed out or stretched to its proper width or tightness without the advantage of Screws in the New Machine or Frame
marked, d, which keep the Clamp board from being circular or bowed in the middle by the stress of the Cloth when screwed out or stretched to its proper tightness - Secondly a moderate length of a piece cannot be finished upon the old frame
at less than three times or lengths and by reason of not being fastened true or square at each end (as upon the New Machine or Frame / but upon the rollers the cross threads or picking is inclined to circular or bowed and not,
+ square over
across the warp when screwed out or stretched to its proper tightnees which prevents the Cloth from stretching so broad as upon the new Machine or Frame, and by that means doth not look so clear and neat... Also the old frame by reason of the
threads or picking at each end of the fame being circular or bowed when screwed out or shetched to its proper width or tightness it is very subject to be damaged or pulled in holes at each corner of the frame when turned upon the rollers at each
end to bring the threads or picking streight or square with the warp - Thirdly suppose a moderate length of a piece or pieces upon an average takes three times, or lengths, to be put in and finished upon the old frame, which frame requires two person
(one at each end) to screw out or stretch the Cloth to its proper tightness which is six times more houble in screwing out one picce of the average length than is required by the New Machine or Frame, which does one piece at a time by one person only
turning either of the handles marked 3 or 4 and with much more accuracy and truth making the Cloth the whole length of the piece of an equal breadth which is a great advantage and which cannot be obtained by the old frame
even with the utmost attention of the finishers.
