WE CHALLENGE the representative of the Singer Sewing Machine Company, or any of the jurors on Sewing Machinea at the Exhibition who voted for the report coining from that body to controvert the following statement of facta. Messrs Meddings, Cunnington, Dale, and Kirk, we call upon you to defend your report. H. C. FISKE A CO. Christchurch International Exhibition. June 15th, 1882. BEPORT OP COMMITTEE OF EXPERTS. To H. C. Fisks k Co. DEAR SIR,— In accordance with yonr request, we have examined tho New Davis and the New Singer Sewing .Machines, for the purpose of comparing them. In our comparison we nave taken into consideration— 1. 'ihe mechanical principle involved. 2. '1 he quality of tho material ustid. 8. The degree of workmanship exhibited. 4. The facility for doing a good and varied class of work. After taking both machines asnndcr, carefully examining every piece, and folly testing their . capabilities, we have no hesitation in saying that we consider the Davis lar the superior machine ot the two. Our reasons are as follows :— In both machines the same method ie adopted for actuating the needle bar— viz., a crank with roller working in a cam. This c«m in the Davis machine is cut out of a solid piece of Bteel and hardened, while in the Singer it is not only very much lighter, but is made of common cast iron. The feed apparatus of the two machines are very dissimilar. That of the Singer is the usual slip feel. The Davis has the vertical feed peculiar to itself. In this arrangement the presser foot holds the material firmly down till the needle hns reached its lowest point. The pressure is then relieved and transmitted to the feed bar. Feed bar, needlo, and material arc then, by a very simple contrivance, moved forward simultaneously the required length of stitch. Motion is'given to the shuttle in Davis' machine as 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 construction to the only moving part under the machine, a pivotted lever having at its end an adjustable shuttle carrier. In the Singer Machine a pair of mitre wheels drive a vertical spindle, having at its lowet end a crank. A connecting rod from this crank moves a sliding shuttle carrier. It will be seen that in tho Davie there are between tho main spindle and the shuttle four points of friction, the pivot carrying the vertical lever, the eccentric, the ball joint, and the pivot of horizontal lever. The tw 5 principal movenionts, the eccentric and ball joint, are adjustable, aud 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 mir e wheels, the two journals of vertical spindle, the two ends of the conn' cting rod, and the sliding shuttle carrier. None of these places nre adjustable. The small wheole are common cast iron, having a certain amount of backlash, and consequent tendency to rattle and break. The connecting rod is a thin bar of iron, with a hole in each end. Tho end which runs on the crank pin is one of the principal joints in the machine, haviug a considerable amount of work to do with small bearing surface, making it very liable to wear, while, as before remarked, there are no menus of compensating for any wear. It will t>e noticed that the shuttle of the Singer Machine is carried in a slide, to which a lateral strain is giv n by the driving rod, causing a certain amount of friction, while in the Davis it is carried by the lever quite free from friction. With the exception of the small roller working the needle bar, there is not a single pieco in the Singer Machine, not even excepting the shuttle, that cannot be cut with an ordinary ppeket knife, and thero are no means of adjusting any -retiring part. In the Davis, not only are most of the pieces made of steel, and tempered, but at every essential point means are provided for taking np any wear. On this point we may say that where wo had any doubt about the quality of the material employed the piece was broken and the fracture carefully examined. Having examined the mechanical arrangements of the two machines, we tested their adaptability for work, and we noticed the very peculiar feed of the Davis. In this respect we have been forced to tho 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 Jhe pressure on a fore motion feed. We must in common honesty express our astonishment at the range and variety of work accomplished by tho Davis, which we ore 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 invalved, and also in performing a greater range of work. We found the Davis to work with cqnal ease from the lightest to the heaviest fabric. JOHN LEE SCOTT (Scott Bros.) Mechanical Engineer, T. GLUYAS PASCOE, Manager of the Kaiapoi ClothiuuFactory. GEO.
