42 NEW PROCESS FOR CLAYING SUGARS. 



Procefs of the After having pointed out the principal difficulties and incon- 

 aut or. vcniences which would refult in the manipulation of the clay- 



ing of fugar, by the ufe of cafes conftruc~ted after the model of 

 thofe of Citizens Boucherie, nothing more remains to be done, 

 than to fhew how I have fucceeded in overcoming thefe diffi- 

 culties, by ufing cafes fabricated according to my own prin- 

 ciples. 

 Con(lr u aion of My cafes are without a bottom ; they are conftru&ed of 

 tacles for r " four boards, united in a fquare by tenons and mortices, which 

 claying fugars, are held clofely together by wedges and pins, fo as to form a 

 dricribed by re-f quare veffe ] each flde () f which j g three feet j infld 



fc.enct to the *• ° 



drawings. meafure. This cafe therefore prefents a furface of nine fquare 



feet. The fide h (fee Plate XII. Vol. II.) is 18 inches high 

 at its extremity e, and 16} inches at its other extremity /. 

 The fide /, parallel to h, is cut in the fame proportions. The 

 height of the fide k correfponds with that of the extremity I; 

 and the fide i, has the fame height as the extremity e. 



I place four cafes, of the conftruction juft def ribed, upon 

 a frame eight feet long, or plank, m, ?n, m, m, having a fall of 

 three inches, and raifed two feet above the ground q q. This 

 board ferves as their bottom. In the fpace occupied by each 

 cafe, it is perforated with twenty holes of an inch in diameter, 

 placed in four rows : thefe holes, which I flop beneath with 

 pins projecting eight inches above the bottom within, ferve 

 for the drainage, when, after the fugar has cooled, thefe 

 fame pins, which perforate it almoft to the half of its thicknefs, 

 are drawn out. 



For receiving the fyrup, I place below the board feveral 

 channels which convey it into a common trough intended to 

 conduft it into a refervoir. Thirty-two cafes difpofed in this 

 manner upon eight boards, in my fugar work, will fupply the 

 place of 900 forms, and as many pots. 



It is evident that by thus inclining the board which ferves as 

 a bottom to the cafes, it was indifpenfibly rcquifite that I 

 fhould give the fame inclination to the lower edges of the fides, 

 in order that this upper part might be at the fame level ; and 

 this inclination was the more neceflary, as it favours the run- 

 ning off of the fyrup at the borders, where the cafes are in con- 

 tact with the board, no lefs than is done by the holes with 

 which it is perforated.
