Robinson's Patent Sugar Mills. 



joint invention of a planter of twenty years' experience, and present 

 eminence, and of an engineer of talent and application, resident in a 

 British sugar colony during the last five years. The details have 

 been perfected here, and the invention has been patented in Eng- 

 land,* France, and their dependencies and plantations abroad, and is 

 in process of being secured by patent in all the sugar-producing 

 countries and colonies. 



Fig. 1, of the engravings on our front page, is a side elevation of 

 this patent Sugar Cane Mill, No. 1, and feed apparatus complete, 

 with one side frame removed for distinctness. In this arrangement 

 it will be seen, that the canes are subjected to three pressures, by 

 which the whole, or nearly the whole of the juice is expected to be 

 expressed ; its extraction being still farther assisted by the applica- 

 tion of a jet of boiling water, or of steam, being thrown upon the 

 canes previous to their entering between the third pair of rollers. 



Fig. 2 is a side elevation of a patent Sugar Cane Mill, No. 2, with 

 its endless band for feeding the canes to the rollers. (One side 

 frame being again omitted.) 



These engravings, although representing but imperfectly two 

 modifications of the machines, will give a better idea of them than 

 any lengthened description. It will be at once perceived by persons 

 having an acquaintance with the subject, that there is nothing com- 

 plex or experimental in the new mill, and that it is adapted to 

 operate more effectively than the common one. 



The distinguishing peculiarities of the new mill, and the advan- 

 tages claimed for it by its ingenious patentees are as follows : — 



1st. That the canes are fed into the mill, or, in other words, put 

 between the pressing cylinders by an apparatus or machine, attached 

 to and worked by the mill itself, by means of which they are sup- 

 plied regularly, evenly, and lengthwise ; instead of being fed in by 

 the hands of the attendant blacks intermittingly and in unstratified 

 bunches, now too little and then too much, which has the double dis- 

 advantage of hindering the action of the cylinders upon a portion of 

 the canes passing through, and of severely straining the machinery. 



2nd. The canes undergo three distinct and consecutive pressings, 

 at each of which the juice expressed is separated from them by being
