Report on the Exhibition of Implements 



durability, with superior brass pistons, valves, tubes, 8cc., so that 

 it is not liable to corrode, and is ready for immediate use after 

 standing any length of time. Price 160Z. 



A portable steam-engine, of six-horse power, on wheels, with 

 shafts, &c., complete, for travelling ; invented, improved, and 

 manufactured by Messrs. Ryland and Dean. Tliis engine has 

 two working cylinders, fitted with superior metallic pistons, and 

 is so simple as to be easily managed by any intelligent farm- 

 labourer. It is manufactured and constructed with every regard 

 to economy of fuel, durability, and efficacy. Price 300Z. 



A portable steam thrashing-machine; invented by Messrs. 

 Tuxford and Sons, of Boston, Lincolnshire, and manufactured 

 by them for Thomas Johnson, of Leicester. The engine is 

 of six-horse power, simple and strong in its construction, and 

 not liable to get out of order. The boiler is small, and well 

 adapted for generating steam quickly, being amply sufficient 

 for this sized engine. It is furnished with wrought-iron welded 

 tubes upon the locomotive principle. The door at the back of 

 the smoke-box, and to which the force-pump is fixed, is double ; 

 thus forming a heating chamber for the water, and security 

 from fire through the door becoming overheated. The chimney 

 is furnished with a spark-trap, so constructed that the sparks 

 are turned downwards into the trap, while the smoke, from 

 its buoyancy, rises. It is also furnished with an ash-pan, well 

 adapted to prevent accidents from fire : the ash-pan contains 

 about three inches of water, so that the ashes falling through the 

 bars, fall direct into the water, and are thus slaked. The front 

 of the ash-pan is furnished with a quadrant- regulator, which closes 

 up securely when the men leave off for their meals; which is a 

 saving of fuel, and at night a great security. The thrashing part 

 is made a great width, to thrash the straw sideways, in order for 

 its being battened : this gives an appearance of bulk to the 

 machine that it otherwise would not possess. The thrashing 

 part is furnished with rollers; so essential to clean thrashing. 

 These are frequently dispensed with, to enable the engine to do 

 more work, but at a sacrifice of good thrashing. It is capable of 

 thrashing from 50 to 100 quarters per day, depending upon the 

 length of the straw, &c., with a consumption of about 8 cwt. of 

 coals. Price 245/. 



By a reference to the time each of the engines worked, it will 

 be perceived that Messrs. Cambridge's and Ryland and Dean's 

 alone continued in action for the whole space of time allotted for 

 the trial by the Judges. This may in a great measure be ac- 

 counted for by the hurry in which some of the engines were got 

 up preparatory to the exhibition, and by the new straps which 

 several of the exhibitors used. Every engine worked its own
