Business Notioes. NOT QUITE SO BEOISIVE AS IT WAS. BUT A LITTLE MOEE OVERWHELMING. WE CHALLENGE tho representative of tho Singer Sewing Machine Company, or any of the jurors on Sewing Machines at the Exhibitioi who voted for tho report coming from that body to oontrovert the following statement of facte. Messrs Meddings, Cunnington, Dale, and Kirk, wo call upon you to defend your report. H. C. FISKE & CO. Christchurch International Exhibition. Juno 15th, 1882. EEPOET OF COMMITTEE OP EXPERTS. To H. C. Fiske <fc Co. DEAE SIR,— In accordance with your request, wo have examined tho New Davis and tho Now Singer Sewing Machines, for the purpose of comparing them. In our comparison we have taken into consideration— 1. The mechanical principle involved. 2. The quality of the material used; 3. The degree of workmanship exhibited. \ 4. The facility for doing 1 a good and varied class of work. After taking both machines asuuder, carefully examining overy piece, and fully testing their capabilities, wo have no hesitation iv saying that we consider the Davis far the snperior machino of the two. Our reasons arc as follows : — In both machines the somo 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 much lighter, but ia made of common cast iron. The feed apparatus of tho two machines are very dissimilar. That of the Singer is the usual slip feed. The Davis bas tho vertical feed peculiar to itself. In thia arrangement tho presser foot holds the material firmly down till the needle has reached its lowest point. The pressure is then relieved and ttansmitted to tho feed bar. Feed bar, needle, and matorial are then, by a . very simple contrivance, moved forward simultaneously the required length of stitoh. Motion is given to the shuttle in Davis' machine as follows. An eccentric at the wheel end of tho 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 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 bo seen that in tho Davis there aro between tho main spindle and the shuttlo four pointßof friction, the pivot carrying the vertical lever, the eccentric, the boll joint, and the pivot of horizontal lever. The tw o principal movements, the eccentric and ball joint, ore adjustable, and the parts most liable to wear are made of liardened steel. To compass the same worlc tho 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 slidingshuttle carrier. None of these places are adjustable. The email wheels aro 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. Tho end which rims on the crank pin is ono of the principal joints in the machine, haviug a considerable amount of work to do with small bearing surface, making it very liable to wear, while, aB before remarked, there are no mean 3of compensating for any wear. It will bo noticed that the shuttle of tho Singer Machine is carried in a slide, to which a lateral strain is given by tho driving rod, causing a certain amount of friction, while in the Davis it is carried by tho lever quite free from friction. With the exception of the small roller working the needle bar, there is not a single pieco in the Singer Machine, not even excepting the shuttle, that cannot be cut with an ordinary pocket knifo, and thero aro no means of ndjusting any wearing part. In the Davis, not only aro most of the pieces made of steel, and tempered, but at evory essential point means are provided for taking np any wear. On this point we may say that where we had any doubt about the quality of tho material employed the piece was broken and tho fracture carefully examined. Having examinod tho mechanical arrangements of the two machines, we tested their adaptability for work, and wo 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 mnslin 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 onr astonishment at the range and variety of work accomplished by tho Davis, which wo aro satisfied cannot be done by the Singer. In summarising our report, we repeat that we have no hesitation in saying that wo rogard the Davis as very superior to the Siuger in workmanship, material, and the mechanical principles invalved, and also in performing a greater range of work. We found tho Davis to worlc with equal caso from the lightest to tho heaviest fabric. JOHN LEE SCOTT (Scott Bros.) Mechanical Engineer. T. GLUYAS PASCOE, Manager of tho Kaiapoi Clothing Factory. GEO.
