PATENTE PELAEZ 



Eata maza puede colocarse facilmente en cualquier trapiche, sea de dos 6 tres mazas. Machuca bien la 

 cana desmenuzdndola y extray^ndole almismo tiempo las dos terceras partes de su guarapo, dejando la caiia bien 

 preparada para el segundo trapiche. Ejecuta todo el trabajo de una desmenuzadora de primera clase y sin mds 

 gasto que cuando se opera con una maza lisa. Esta maza es de acero y se ha sacado privilegio para ella en todas 

 las partes del mundo donde se cultiva la cana de aziicar. Pues envienos un dibujo de la maza superior que usan 

 U is asi que de su eje, y les cotizaremos precioj bajos per una maza completa para desmenuzar la cana de este 

 trapiche.

COALING AT HAVANA 



The port of Havana is well equipped for 

 the supply of bunker coal to steamers, the 

 principal coaling company there having five 

 traveling bridge transporters with which 

 grabs are used for discharging colliers and 

 reloading into barges. A cargo of 8,200 

 tons can be discharged and stacked for 

 storage at the wharf, or loaded into barges 

 in 16 hours. 



The same company has a fleet of six 

 mechanically-equipped barges for bunkering. 

 The.se barges, which are used generally in 

 pairs, are capable of giving a continuous 

 dehvery of 300 tons per hour, but as an 

 example of quick de.spatch at Havana it 

 is to be noted that these barges were recently 

 engaged in supplying bunkers to a steamer, 

 and 1,800 tons were shipped in seven hours, 

 this time including delays and stoppages 

 for trimming. 



The discharging plants, which are ail 

 worked by steam power, have command of 

 a wharf frontage 1,100 feet in length, and 

 they have a waterside span of 80 feet, whereby 

 barges lying off a collier can be loaded direct. 



All the bunkering barges referred to, with 

 one exception, are old sailing vessels which 



have been dismantled, leaving only the 

 hulls, which are constructed of hard timber, 

 these having been adapted to provide self- 

 trimming holds divided into compartments, 

 and to suit the mechanical ecjuipment. 



The mechanical arrangement comprises 

 a continuous-chain conveyor, with equally 

 spaced buckets attached, and is driven by 

 a steam plant situated at the fore part of 

 the craft; this conveyor pas.ses horizontally 

 under the hold from which the buckets are 

 filled, the loaded buckets then rise in the 

 tower frame at the bows; the direction of 

 the conveyor is changed to the horizontal 

 at the top of the tower, the buckets being 

 automatically tipped into a hopper, the 

 coal then passes to an adjustable telescopic 

 chute by which it is deUvered. The empty 

 buckets return above the loaded ones, 

 descending down the tower from along the 

 top of the hold and thence under the hold 

 again for refilling. 



With these discharging, loading and 

 bunkering equii)ments referred to about 

 400,000 tons of coal are supjilied to vessels 

 bound to and from Mexican Gulf ports, and 

 it is probable that Havana will become of 

 greater prominence with the further develop- 

 ment of the Panama route.
