498 Eeport on the Trials of Implements at Oxford. 
iron boiler-pan, holding GO gallons, for boiling water, linseed compounds, &c.> 
maize, barley, or for brewing puqDoses. This boiling pan has an escape-pipe 
from the jacket, which takes the steam into the bottom of the pan. Besides 
economising fuel by this arrangement, we insure the agitation of the materials 
that may be operated on, and jirevent their settling. The condensed steam is 
collected in a vessel, to be again pumped into the boiler. 
Messrs. Amies, Barford, and Co.'s Steaming Apparatus, No. 232. 
In the first trial with this apparatus, the steam was up and ready for use in 
16 minutes after the fire was lighted. The GO- gallon pan-full of cold water 
was raised to 180° in 275 minutes ; 2 bushels of maize placed in the water 
thus heated was boiled in 3G minutes. In tlie second exix;riment the steam- 
ing pan was filled with chaff, and steamed for 10 minutes, demonstrating the 
capacity of the apparatus for such work, where it is considered desirable. This 
pan is also reversible, being attached to the boiler by a ball and socket joint ; 
thus it can readily be emjitied and cleaned, without detachment from the 
boiler. In a short trial, which was undertaken to show the capacity of the 
boiler to generate steam, the temperature of the water in the pan was 190° at 
commencement ; time, 30 minutes ; 55 lbs. of water pumped in ; coal con- 
sumed, 4 lbs. ; temperature of water in pan at end of exjierimcnt, 208°. 
The same height of water in boiler and pan at the eiul of trial as at the 
beginning. 
No. 235. Price, 19?. 10s. — This was precisely similar to Jso. 232, only 
smaller. The steam generator is on the same principle. The vessels hold 
6 bushels and 40 gallons respectively. Such a steamer would supply the 
requirements of 30 cattle and 50 pigs, and the cost of steaming chaff will not 
exceed 3d. and jiotatocs Gd. a ton for fuel. The steam was got up in 18 
minutes, and the pan-full of old tough potatoes, which were well cooked, in 
46 minutes. 
Valentine Barford. Xo. G75G. Price, II. 10s. — In this the water encircles a 
cast-iron corrugated fire-box ; the boiling pan and steamer, which are placed in 
connection ; the latter being at the top contains 35 gallons of fluid, 3 bushels of 
roots, chaff, &c. The apparatus simple and easy to clean, and might be useful 
to market-gardeners or small occupiers.
