598 Implement Show at Bury St. Edmund's. 



fence, a moveable iron grating is so arranged as to fall and close the inoutli. 

 In its present form this arrangement is rather inconvenient to the feeder, 

 interfering with the regularity of the feed. 



Nalder and Nalder's machine, which received the third prize is novel in some 

 respects. The winnowing apparatus is driven hy a simple eccentric, which 

 appears to work well; the shakers are driven hy a friction-pulley, and the 

 travelling-wheels are of cast-iron with semi-hollow felloes. 



It would be hardly fair to pass unnoticed the machines of Messrs. Holmes 

 and Sons, Norwich, and Messrs. Clayton, Shuttleworth, and Co., Lincoln, 

 although owing to the power consumed neither were eligible for the prize. 

 The construction of both is good, the Lincoln firm being Avell known for the 

 excellence of their workmanship, whilst Messrs. Holmes clean the chaff by a 

 very simple arrangement. As both these makers will be referred to hereafter 

 we abstain from further comment now. 



Having the arrangement of the money in our own hands, we considered it 

 desirable to award three prizes, viz. : — 



First j^rize, Messrs. Eansomea and Sims. 



Second prize, E. Humphries. 



Third prize, Nalder and Nalder. 



It is worthy of note that W. S. Undcrhill's machine was the only one fitted 

 with his patent blast-elevator. 



Class C. 



In this class we have all those finishing machines that are suj)posed to dress 

 lip the sample ready for delivery. Eight entries came under consideration ; 

 the trials were on the same principle as before. Three bushels of the head- 

 corn from each lot were passed through one of Boby's finishing-machines, as 

 a test of merit. The quantity of light corn, &c., thus removed varies very 

 considerably, and proves the correctness of our views as to the imperfec- 

 tions of these machines. No farmer who values his character as a good 

 deliverer would like to offer such samples in a market. The following table 

 give the results of the preliminary canter. 



Messrs. Holmes and Son's machine, with the drum nearer the centre than 

 is common, is well balanced, strongly made, and steady in its working. The 

 corn is elevated to the top and above the shakers, and winnowed by a cross- 

 blast, the winnowing-box having a face of fine perforated zinc wire; the dirt 

 and seeds are blown away, the chaff is sacked well. To obtain this cross-blast 

 either mitre-wheels or friction-wheels are necessary, the latter are used in 

 this case : not, perhaps, the best mechanical arrangement, as these wheels and 

 the shaftings are somewhat in the way and very unsightly, yet they are well 

 balanced and work quietly. The box-shakers have edge-beaters, which tend 

 to keep the straw up and thus assist the jerking action ; they are driven by 

 a double crank and connecting-rod. The rotary screen is regulated by a 

 change of speed, sending the corn through with greater or less rapidity, 

 according as much or little tail requires removal. Goucher's beaters are used, 

 but in addition is a plain convex beater. A trap-door at end of the hummeller 

 converts this into a single blower, if re(iuired. 



In Clayton and Shuttleworth's machine the drum-spindle is attached to a 

 strong bracket, which, although somewhat unsightly, steadies the drum and 

 saves the brasses. Penny's screen is used. The workmanship is excellent, 

 and the machine has a compact and trim appearance that looks like work. 

 Everything is made as simple as is practicable. 



The table given at p. 600 embodies the facts arrived at, and will sufficiently 

 explain the reasons for our decisions.
