WE CHALLENGE the representative of tho Singer Sewing Machine Company, or any of the jurors on Sewiug Machines at tho Exhibition who voted for the report coming from that body to controvert the following statement of facts. Messrs Meddings, Cunningtou, Dale, and Kirk, we call upon you to defend your report. H. C. PISKE k CO. Christclmrch International Exhibition. June 15th, 1882. REPORT OF COMMITTEE OF EXPERTS. To H. C. Fiske & Co. DEAR SIR,— In accordance with your request, wo have examined the New Davis and the New Singer Sewing Machines, for the purpose of comparing them. In our comparison we have taken into consideration — 1. The mechanical principle involved. 2. 'lho quality of the material used. 3. The degree of workmanship exhibited. 4. The facility for doing a good and varied class of work. After taking both machines asunder, carofully examining every piece, and fully testing their capabilities, we havo no hesitation in Baying that we consider the Davis far the superior machine 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. Thiß cum in the Davis machine is cut out of a solid piece of steel and hardened, while in the Singer it is not only yery much lighter, but is made of common cast iron. The feed nppnratns of the two machines are very dissimilar. That of the Singer is tho usual slip feeJ. 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 thon relieved and transmitted to the feed bar. Feed bar, needle, and material are then, by a very simple contrivanco, move* forward simultaneously the required length Of stitch. Motion isigiven 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, u pivotted lever having at its end an adjustable shuttle carrier. In the Singer Machine a pair of niitro wheels drive a vertical spindle, having at its lower ond a crank. A connecting rod from this crank moves a sliding shuttlo carrier. It will be seen that in the Davis there are between the main spindle and tho shuttle four points of friction, the pivot currying th* vertical lever, the eccentric, the ball joint, and the pivot of horizontal lever. Tho two principal movements, tho eccentric and ball joint, we adjustable), and tho parts most liable to wear are mode of hardened steel. To compass the some 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. Nono of these pluces are adjustable. The small wheels 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. The end which rnns 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 nny wear. It will be noticed that the shuttlo of tho Singer Machine is carried in a slide, to which a lateral strain is {riven by tho driving rod, causing 1 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 cannot be cut with an ordinary pocket knife, and there aro no means of adjusting any wearing part. In the Davis, not only are most of tho 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 hud any doubt about the quality of the material employed the piece was broken and tho fracture carefully examined. Having examined the mechanical arrangements of the two machines, wo tested their adaptability for work, and we noticed tho very peculiar feed of the Davis. In this respect we 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 tho 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 Davis, which wo are satisfied caundt be done by the Singer. In summarising our report, we repeat that wo havo no hesitation in saying that we regard the Davis as very suporior to the Singer in workmanship, material, and tho mechanical principlos 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. GLUYAS PASCOE, Manager of the Kniapoi Clothing Factory. GEO.
