Business Notioei. NOT QUITE SO DECISIVE AS IT WAS, BUT A LITTLE MOEE OVERWHELMING. "•TTITE CHALLENGE tlie representative of the yfjf Singer Sewing Machine Company, or any of the jurors on Sewing Machines at the Exhibitioi who voted for the report coming from that body to controvert the following statement of facts. Messrs Meddings, Cunnington, Date, and Kirk, we coll upon you to defend your report. H. C. PISKE & CO. Chriatchurch International Exhibition. June 15tb, 1882. EEPOBT OP COMMITTEE OF EXPERTS. To H. C. Fiske * Co. DEAR SIR,— In accordance with your request, we have examined the New Davis and tho New Singer Sewing Machines, for the purpose of comparing them. In our comparison we have take#, into consideration— 1. The mechanical principle involved. 2. The quality of the material ustd. 3. The degree of workmanship exhibited. i. Tho facility for doing a good and varied class of work. After taking both machines asunder, carer ally examining every piece, and folly testing their capabilities, we have no hesitation in saying that we consider the Davis far the superior machine of the two. Our reasons ore as follows :— In both machines the same method is adopted for actuating the needle bar— viz., a crank with roller working in a cam. This cam in the Davis machine is cut out of a solid piece of steel and hardened, while in the Singer it is not only very ranch lighter, but is made of common cast iron. The feed apparatus of the two machines ore very dissimilar. That of the Singer is the usual slip feed. The Davis has the vertical feed peculiar to itself. In this arrangement the presser foot holds the material firmly down till the needle has reached its lowest point. The pressure is then relieved and tr ansmitted_ to the feed bar. Feed bar, needlo, and material are then, by a very simple contrivance, moved forward simultaneously the required length of Btitoh. Motion is given to tho shuttle in DaviB 1 machine 08 follows. An eccentric at the wheel end of the main spindle gives motion to a vertical lever. This in turn traasmits it throngh 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 lower end a croak. A connecting rod from this crank moves a sliding shuttle carrier. It will be seen that in the Davia there are between the main spindle and the shuttle four points of friction, tho pivot carrying the vertical lever, the eccentric, the ball joint, and tho pivot of horizontal lever. The tw d principal movements, the eccentric and 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 ahuttle carrier. None of these places are adjustable. The small wheels are common cast iron, having a certain amount ©f backlash, and eonsequent tendency to rattle and break. The connecting rod is a thin bar of iron, with a hole in each end. The end which 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 befora remarked, there are no means of compensating for any wear. It will be noticed that the shuttle of tho Singer Machine is carried in a slide, to which a lateral strain is given 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 piece in the Singer Machine, not even excepting 1 the shnttle, that cannot be cut with an ordinary pocket knife, and there ore 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 essential point means are provided for taking up any wear. On this point wo may say that where we had any doubt abont the quality of tho 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 the pressure on a fore motion feed. We must in common honesty express our astonishment at tho range and variety of work accomplished by the Davia, which wo are satisfied cannot be done by tho Singer. In summarising our report, we repeat that we have no hesitation in saying that we regard the Davis as very superior to tho 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 equal ease from the lightest to the heaviest fabric. JOHN LEE SCOTT (Scott Bros.) Mechanical Engineer. T. GLTJTAS PASCOE, Manager of the Kaiapoi Clothing Factory. GEO.
