Business Koticoi. NOT QUITE SO BECISIVE AS IT WAS, BUT A LITTLE MORE OVEEWHELJUNG. WE CHALLENGE the representative of the Singer Sewing Machine Company, or any of the jnrora on Sewing Machines at the Exhibitioi who voted for the report coming from that body to controvert the following statement of facts. Messrs Meddings, Cunnington, Dale, and Kirk, we call npos yon to defend your report. H. C. PISKE & CO. Christehnrch International Exhibition. June 15th, 1882. EEPOET OF COMMITTEE OF EXPERTS. To H. C. Fiskk & Co. TTkEAE SIR,— In accordance with your request, JLJ 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. 3. 'J he quality of the material used. 3. The degree of workmanship exhibited. 4. The facility for doing a good and varied closb of work. After taking both machines asunder, carefully examining every piece, and folly testing their capabilities, we have no hesitation in saying that we consider the Davis far the superior machine of the two. Our reasons are as follows :— In both mnohinea the Biune method ia adopted for actuating the needle bar — viz., n crank with roller working in a coin. This cam in the Davis machine is cut out of a solid piece of steel amd hardened, while in the Singer it is not only very much lighter, but is nmde of common oast inn. The feed apparatus of the two machines ore very dissimilar. That of tho Singer is tho usual slip feed. The Daris has the vertical feed peculiar to itself. In thiß arrangement the prasser foot holds the material firmly down till the needle has reached its lowest point. The pressure is then relieved and transmitted to the f««d bar. Foed bar, needle, and material are then, by a. very simple contrivance, moved forward simultaneously the required length of stitoh. Motion is given to the shuttle in Davis' maohino as follows. An eccentric at the wheel end of tb« stain spindle gives motion to a vertical lever. Thus ia turn transmits it through a boll joint of ingenious construction to the only moving part wider the machine, a pirotted lever having at its end an adjustable shuttle carrier. In the Singer Machine a pair of mitre whcelß drive a vertical spindle, having at its lower end a crank. A connecting rod from this crank moves a sliding shuttle carrier. It will be seen that in the Davis there are between tho 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 tw 3 principal move monts, the eccentric and ball joint, are adjustable, and the parts most liablo to wear are mode 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 email wheels are common enst 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 and which runs on tho 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 liablo 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 elide, 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 cannot be cut with an ordinary pocket knife, and there are no meaus of adjusting any wearing part. In the Davis, not only are most of tho pieces made of steel, nnd tempered, but at every essential point means ore provided for taking np any wear. On this point we may say that where we had any doubt about the quality of the material employed the piece was broken and the fructure carefully examinod. Having examined the mechanical arrangements of the two machines, we tested their adaptability for work, and we noticed the very peftnlior feed of tho Davis. In this respect we have been forced to the conclusion that for all purposes, sewing from the thinnest muslin to eveu 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, which 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 snperior to the Singer in workmanship, material, and the mechanical principles invalved, and also in performing a greater range of work. We found the Davis to work with equal ease from the lightest to the heaviost fabric. JOHN LEE SCOTT (Scott Bros.) Mechanical Engineer. T. GLUTAS PASCOE, Manager of the Kaiapoi Clothing Factory. GEO.
