NOT QUITE SO DECISIVE AS IT WAS , BUT A LITTLE MORE OVEBWHELMING. Wifi 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 Meddlnga, Onnnington, Dale, and Kirk, we call upon yon to defend your report, H. C. FIBRE & CO. Christchurch International Exhibition, June 15tb, 1882. REPORT OF COMMITTEE OF EXPERTS. To H. 0. Fiskb & Co. DEAR SIR, —In accordance with your request, we have examined the New Davis and the New Singer Sewing Machines, for the purpose of comparing them. In our comparison we have takea into consideration— 1. The mechanical principle Involved 2. The quality of the material u?ed 3 The degree of workmanship exhibited 4, The facility for doing a good and varied o asa of work. After taking both machines asunder, carefully examining every piece, and fully testing their capabilities, we have no hesitation in saying that wo consider the Davis far the superior maohice of the two. Our reasons are 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 oat 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 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 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 Is givt n to the shuttle In the Davis machine as follows An eccentric at the wheel end of the main spindle gives motion to a vertical lover. This in turn transmits It through a ball joint of ingenious construction to the only moving part under the machine, a pivotted lover 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 crank A connecting rod from this crankjnoves 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 j olnt, 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 carrier None of these places are 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 id a thin bar of iron, with a hole in each end. The end which runs on the crank pin is one of the prinoipal joints in the machine, having a considerable amount of work to do with small bearing surface, making it very liable to wear, while, as bef ore 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 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 the shuttle, that casnot be out 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 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 was broken and the fracture carefully examined. Having examined the mechanical arrangements of the two machines, we tested their adaptability for work, end wa noticed the very peonliar feed of tho 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 parallel or 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 tho Davis, which we are satisfied cannot be done by the Singer. In summaridcg 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 greater range of work. Wo found the Davis to work with equal ease from the lightest to the heaviest fabric. JOHN LEE SOOTT (Scott Bros.), Mechanical Engineer. T. GLDYAS PA3COE, Manager of the Kaiapol Clothing Factory. GEO.
