H. a FIBKE & CO. Chrlotchurch Interactional Exhibition, June 15th, 1882. REPORT OF COMMITTEE OF EXPERTS. To H. C. Fiske & Co. >EAR SIB, —In accordance with yonr request, wa have examined the New Davis and the New Singer Sewing Maohines, for the purposo of comparing them. In oar comparison wa have take a into consideration— 1. 'I he mechanical principle Involved 2. The quality of the material used 3- The decree of workmanship exhibited 4. The facility for doing a good aud varied o aes of work. After taking both machines asunder, carefully examining every piece, and fully testing their capabilities, we have no hesitation in eaying that wo consider the Davis far the superior machine of the two. Our reasons are as follows : In both machines Vn& same method is adopted for t cfcnating the needle bar, viz , a crank with roller working in a cam. This cam in tho Davis Machine is ont out of a solid piece of steel and hardened, while in tho Singe? it is not only very much lighter, ; bnt is made of common oast iron.

The feed apparatus of the two machines are very dissimilar. That of the Singer la the usual Blip feed. The Davis has the vertical feed peculiar to ltiolf. In this arrangement the preaaer foot holds the material firmly down till the needle has reached its lowest p?int. The pressure is then relieved and transmitted to the feed bar. Feed bar, needle, and material are then, by a very simple contrivance, moved forward simultaneously the required length of stitch.

Motion ia giv< n to the shuttle In the Davis maohine as follows An eccentric at the wheel end of the main spindle gives motion to a vertical lever. This in tarn transmits it through a ball joint of ingenious construction to the only- moving part under the maohine, a pivotted lever having at Its end an adjustable shuttle carrier. In the Singer Machine a pair of mitro wheels drive a vertical spindle, havi-jg at its lower end a crank. A connecting rod from this crank moves a sliding dhnttle carrier. It will be seen that in the Davis there are between the main spindle and the shuttle four points of friction, the pivot oanying the vertical lever, the eccentric, tho 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 compass the same work the Singer employs as points of friction the teeth of the mitre wheels, the two journals of vertical spindle, the two ends of the connecting rod, and the sliding shuttle cariier None of these places are adjustable. The small wheels are common cast iron, having a certain amount of backlash, and consequent tendenoy to rattle and and break. The connecting rod la a thin bar of iron, with a hole in each end. The end wbioh 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 tho shuttle of the Singer Maohine ie carried in a slide, to wbioh a lateral strata is given by the driving rod, causing a certain, amount of friction, while In the Davis it in cirricd by the lever quite free from f riot ion. With the exception of the small roller working tho noedle bar, there is not a single piece in the dinger Maohine, not even excepting the shuttle, that ca- not be cut with an ordinary pocket knife, and there are no means of adjusting any wearing part. In the Davis not only are most of the pieces made of steel, and tempered, but at every essentia] 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 was broken and tho fracture carefully examined. Having examined the mechanical arrangements of the two machines, we tested their adaptability for work, and we noticed the very peouliar feed of the Davis. In this respect wo have been forced to the conclusion) that for all purposes, sewin from the thinnest muslin to even throu h a metal spoon, the Davis has no paralle grasp, or for avoiding that puckering often the effect of the pressure on a fore 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 snperlor to the ginger in workmanship, material, and the mechanical principles involved, and also in performing a greater range cf work. We found the Davia to work with tqnal eaae from the lightest to the heaviest fabric. JOHN LBS SCOTT (Scott Bros.), Mechanical Engineer. T. GLUYAS PA9COE, Manager of the Kaiapoi Clothing Factory.
