Fis__ k Co. DEAB SIB,— In accordance with your request, we have examined the New Davis and the New Singer Sewing; Machinea, for the purpose of comparing them. In our comparison we hare taken into consideration— 1. The -mechanical principle Involved. 3. The qoality of the material us*-. 3, The de-jree of workmanship exhibited. i, The facility for doing a good and varied olflflS of work. After taking both machinea asunder, oarefully examining every piece, and fully testing their capabilities, we hare 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 ont of a solid piece of steel and hardened, while in the Singer it is not only very mnch lighter, but is made of common cast iron. The feed apparatus of the two machines are very dissimilar. That of the Singer ia the usual slip feed. The Davis has the vertical feed peculiar to itself. In this arrangement the presser foot holds the material flrnuy 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|given to the shuttle in Davis' machine as follows. An eccentrio at the wheel end of the main spindle gives motion to a vertical lever. This in turn transmits it through a hall 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 Machinea pair of mitre wheels drive a vertical spindle, having- at its lower end a crank. A connecting rod from this crank moves a sliding shuttle carrier. It will he 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 eccentrio, the hall joint, and the pivot of horizontal lever. The tw o principal movements, the eccentric and ball joint, ore adjustable, and the ports most liable to wear axe 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 oonnpeting rod, and the eliding shuttle carrier. None of these places are adjustable. The small wheelß are common cast iron, having a certain amount ot 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 runs on the crank pin is one of the principal joints in the machine, having a considerable amount of work to do with Bmall bearing surface, making it Tory 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 friction, while in the Davis it is carried by the lever quite free from friction. With the exception of the smalt 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 au ordinary pocket knife, and there are no means of adjusting any wearing part. In tho Davis, not only are inoßt of the pieces made of steel, aud tempered, hut at every essential point means are provided for taking ap any wear. On this point we may say that where we had any doubt about the quality of the material employ-d 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 vei*y 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 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 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 involved, 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. GLUTAS PASCOE, Manager of the Kaiapoi Clothing Faotory. GEO.
