Patent steam riveting machine bour pan, for evaporating sugar-cane juice.
COOK'S PATENT STEAM PUNCHING, SHEARING, AND RIVETING MACHINE effects the three operations in one frame, or, when desired, it is made for riveting only. It can punch thirty holes per minute in ordinary boiler plates. The action of the punch being instantaneous, and every stroke under the control of the keeper, insures both accuracy and speed. In riveting, ten holes can be closed up in one minute, and the work much superior to that effected by hand. Steam pressure required, 25 lbs. per square inch. Prices, designs, and testimonials to be had on application.
BOUR'S PATENT EVAPORATING PAN for the concentration of all liquids.
Having become the proprietors of the patent for this pan, D. Cook and Co. have introduced a considerable number of them into the various sugar-growing countries, and from the superior mode of construction which they have adopted, can recommend them with every confidence.
This pan consists of ten hollow discs of copper, about 3 ft. diameter, mounted on an axis 10 ft. long, and of a form which allows the exhaust steam, under a pressure of 2 lbs. per square inch, to communicate freely with all the discs, and, at the same time, carrying off the water of condensation at the other end. This revolver turns at a speed of twenty revolutions per minute, in a semi-cylindrical pan of copper, supplied with liquor from the battery, and will cook 12 cwt. of sugar per hour, from 20°. Beaume, the temperature not exceeding 170° Fahrenheit.
Prices, designs, etc. may be had on application.
