Messrs Meddings, Cunnington, Dale, and Kirk, we 'call upon you to defend your report. H. C. PIBKE & CO. Christohuroh International Exhibition, June 15th, 1882.' REPORT OF COMMITTEE OF EXPERTS. To H. C. Fiske & Co. DEAR SIR,—In accordance with your request, we have examined the New Davis and the New Singer Sewing Maohines, for the purpose of comparing them. In our comparison we have take.) into consideration— 1. Ihe mechanical prinolpls involved 2. The quality of the material used 3. The decree of workmanship exhibitsd

4. The facility for doing a good and varied o ass of work. After taking both machines asunder, carefully examining every piece, and fully testing their capabilities, we have no hesitation in Baying that wo consider the Davis far the superior machine of the two. Our reasons are as follows : In both machines tie same method is adopted for actuating the needle bar, viz., a orank with roller working in a cam. This com In the Davis Macbiae is cut out of a solid piece of steel and hardened, while in the Singer it is not only very much lighter, but is made of common oast iron. The feed apparatus of tbe two machines are very dissimilar. That of the Siuger is the usual Blip feed. The Divls has the vertical feed peculiar to itielf. In this arrangement tho pressor foot holds the material firmly down tiil the needle has reached its lowest point. The pressure is ! tben relieved and transmitted to the feed bar. Feed bur, needle, and material are then, by a very simple oontrivanoe, moved forward simultaneously the required length of etitoh. Motion is given to the shuttle in the Davis maobine ss follows An eccentric at the wheel end of the main spindle gives motion to a 'vertical lever. This in turn transmits it through a ball joint of ingenious conatruo tlon to the only moving part under the machine, a pivotced lever having at its end an adjustable shuttle carrier. In the Singer Machine a pair of mitre wheels drive a vertical spindle, havL g at its lower end a orank, A connecting rod from this crank moves a sliding shuttle carrier. It will be seen that In tbe Davis there are between the main spindl'3 end the shuttle four points of friction, 'he pivot carrying the vertical lever, the eocoMtric, the ball joint, and the pivot of horizontal lever The two principal movements, the eccentric and the ball joint, are adjustable, and the parts most liable to wear are made of hardened steel. To oompsss the same work the Singer employs as points of friotion the teeth of the mitre wheels, the two journals of vertioal spindle, the two ends of the connecting rod, and the sliding shuttle carrier. None of these places are adjustable. The small wheels are common oast iron, having a certain amount of backlash, and consequent tendency to rattle and and break. The connecting rod iu a thin bar of iron, with a hole in each end. Tbe end whioh runs on the crank pin is one of the principal joints in the machine, having a considerable amount of work to do with small bearing surface, making it very liable to wear, while, as before remarked, there are no means of compensating for any wear,' It will be noticed that the shuttle of the Singer Machine Is carried in a slide, to whioh a lateral strain is given by the driving rod, causing a oertain amount of friotion, while in the Davis it is carried by the lever quite free from friotion. With the exception of the small rol!or working the needle bar, there is not a single piece in the dinger Machine, not even excepting the shuttle, that ca not be out with an ordinary pooket knife, and there are no means of adjusting any wearing pari. In the Davis not only aro most of tbe pieces made of steel, and tempered, but at every essential point means are provided for taking up any wear. On this point we may say that where we had any doubt about the quality of the material employed the the piece wait broken and the fracture carefully examined. Having examined the mechanical arrangements of the two machines, we tested their adaptability for work, find we noticed the very peculiar faed of the Davis. In this respect wa have been forced to the conclusion that for all purposes, sewing from the thinnest muslin to even through a metal spoon, the Davis has no parallel for grasp, or for avoiding that puckering often the effect of the pressure on a f jre motion feed. We must in common honesty express our astonishment at the range and variety of work accomplished by the Davis, whioh we are satisfied cannot be done by the Singer. In summarising our report we repeat that we have no hesitation in saying that we regard the Davis as very superior to the Singer in workmanship, material, and the mechanical principles involved, and also in performing a greator range of work. We round the Davis to work with equal ease from the lightest to the heaviest fabric JOHN LEE SOOTT (Scott Bros.), Mechanical Engineer. T. GLUTAS PABCOE, Manager of the Kaiapoi Olothing Faotory. GEO.
