NOT QUITE SO DECISIVE AS IT WAS BUT A LITTLE MORE OVERWHELMING. WE CHALLENGE the representative of the Singer Sewing Machine Company (> or any of the jurors on Sewing Machines at the Exhibition who voted for the report coming from that body to controvert the following statement of facts Messrs Meddings, Ounnington, Dale, and Kirk, we call npon you to defend your report. H. C. FIBKE & CO. Christchnrch International Exhibition, June 15th, ISS2. REPORT OF COMMITTEE OF EXPERTS. To H. C. Fiskk & Co. "|pvEAR SIS,—In accordance with your ' 9 request, we have examined tbe New Davis and the New Singer Sewing Machines, for the purpose of comparing them. In out comparison we have taken into consideration— 1. The mechanical principle Involved 2. The quality of the material u-ed 3. The depree of workmanship exhibited 4. The facility for doing a good atid varied a ass of work. After taking both machines asunder, carefully examining every piece, and fully testing their capabilities, we have no hesitation in saying that we consider the Davis far the superior maohice of the two. Cur reasons are as follows : In both machines the same method is adopted for actuating the needle bar, viz , a or:<nk 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 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 Blip feed. The Davis has the vertical feed peculiar to itself. In this arrangement tha preeser foot holds the material firmly down till the needle haß reached its lowest point. 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 utitch. Motion in giv.- n to the shuttle In the Divis machine its follows An 6ccontric at the wheel end of the main spindle gives motion to a vertical lever. This in turn transmits it through a bad joint of ingenious construe tlon to the only moving part under the machine, a pivotted lever having at its end an adjustable Bhuttle carrier. In the Singer Machine a pair of mitrr: wheels drive a vertical spindle, haviog at its lower end a crank. A connecting rod from this crank move 3 a sliding shuttle carrier. It will be seen that in the Davis there are between the 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 two principal movements, the eccentric and the ball joint, are adjustable, and the parts most liable to wear are made of hardened steel. To oompass the s&me work the Singer employs as points of friction the teeth of the mitre wheals, the two journals of vertical spindle, the two ends of the connecting rod, and the sliding shuttle canier None of theße places ore adjustable. The small wheels are common cast Iron, having a certain amount of backlash, and consequent tendency to rattle and and break. The connecting rod is a thin bar of iron, with a hole in each end. The 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 which a lateral strain is given by the driving rod, causing a certain amount of frlotion, while in the Davis It is curried by the lever quite free from fr otion. With the exception of the small roller working the needle bar, there is not a single piece in the Singer Machine, not even excepting the shuttle, that oa- 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 ths quality of the material employed the the pleae was broken and the fracture carefully examined. Having examined the mechanical arrangements of the two machines, we tested their adaptability for work, end we noticed the very peculiar feed 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 involvod, and also in performing a greater range of work. We found the Davis to work with eqnal ease from the lightest to the heaviest fabric JOHN LEE SOOTT (Scott Bros.), Mechanical Engineer. T. GLUYAS PABCOE, Manager of the Eaiapoi Clothing Factory. GET.
