Business Notioes. NOT QUITE SO DECISIVE AS IT WAS, BUT A LITTLE MOEE OVERWHELMING. WE CHALLENGE the representative of the Siugor Sewing Machine Company, or any of the jurors on Sewing Machines at the Exhibitioi who voted for the report comins from that body to controvert the following statement of facts. Messrs Meddiugs, Uunnington, Dale, and Kirk, wo cull upon you to defend your report. H. C. FISKE & CO. Christchnvch International Exhibition. June 15th, 1882. REPORT OF COMMITTEE OF EXPERTS. To H. C. Fiskk <fc Co. DEAR SIX, — In accordance with your request, we have examined the Now Davis and tho New Singer Sewini* Machines, for the purpose of comparing them. In our comparison we have taken into consideration— 1. 'i'ho mechauical principle involved. 2. 'I'ho quality of the material usud. 8. The degree of workmanship exhibited. 4. The facility for doing a good and varied class of work. After taking both machines asnnder, carefnlly examhijnsr every pieco, nnd fnlly testing their capabilities, we have no hesitation iv saying that we consider tho Davis far the superior machine of the two. Our reasons are as follows : — In both machines the same method is adopted for aetimting the needle bar — viz., a crank with roller working in a cam. This cum in tho Davis machine is cut out of a solid piece of steel and hardened, while in tho Binder it is not only very much lighter, but is made of common cast iron. Tho feed apparatus of the two machines are very dissimilar. That of tho Siuger is tho usual Blip fool. The Davis has tbo vortical feed peculiar to itself. In this arrangement the presser foot holds tho mntorial firmly down till tho needle bus reached its lowest point. Tho pressure is then relieved and transmitted to tho teed' bar. Feed bar, needle, and material are tben, by a • very simple contrivance, moved forward simultaneously tho required length of stitch. Motion is^given to tho Bhuttle in Davis* machine as follows. An eccentric at tho wheel end of the main apindlo gives motion to a vertical lever. This in turn transmits it through a ball joint of ingouions construction to the only moving part under the machine, .' 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 crank moves a sliding shnttle carrier. It will bo seen that in the Davis thero are between the main spindle and the shuttle four points of friction, tho pivot carrying the vertical lever, tho eccontrio, the ball joint, nnd the pivot of horizontal lever. The twj principal movoments, tho eccentric and ball joint, are adjustable, and the parts most liable to wear aro made of hardened steel. To compnsa the same work tho Singer employs ns points of friction the toeth of tho mi 1 re wheels, tho two journals of vortical spiudle, the two ends ot' the connecting rod, and thn sliding shuttle ca'rier. Koue of these places aro adjustable. Tho small 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 ond which runs on tho crank pin is one of the principal joints in the machino, having ft considerable amount of work to do with small bearing surface, making it very liable to wear, while, as before remarked, thero are no means of compensating for any wear. It will le 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 curried by the lever (jnite free from friction. With the exception of the small roller working the needle bar, there is not a single pieco in tho Singer Machine, not even excepting the shuttle, that cannot be cut with an ordinary pocket knife, and thero are no means of adjusting any wearing part. Iv tho Davis, not only are most of the pieces nindc of steel, and tempered, but at overy essential point moans are provided for taking up any wear. On this point we may say that where wo hid any doubt about tho quality of tho mntorial employed the pieco was broken and the fracture carefully examined. Having examined the mechanical arrangements of the two machines, vo tested their adaptability for work, and we noticed tho very peculiar fpud of tlw Duvis. In this respect wo havo boon forced to tho conclusion that for all purposes, sewing from tho thinnest muslin to eveu through a metal spoon, the Davis has no parallel for grasp, or for avoiding that puCiteriug often the effect ot the prossuro on a fore motion feed. We must in common honesty express our astonishment at the range and variety of work accomplished, by the Davis, wluoh w,c are satisfied cannot be douo by the Singer. In summarising our report, we repeat that we have no hesitation in myiug that we regard the Davis as very superior to the Singer in workmanship, material, uud the mechauical principles invnlvod, and nlso in performing a greater range of work. We found tho Davis to work with equal case from the lightest to the heaviest fabric. JOHN LEE SCOTT (Scott Bros.) Mechanical Engineer. T. GLUT AS I'ASCOE, Manager of tho Kuiapoi Clothing Factory.
