WE CHALLENGE the representative of tho Singer Sewing Machine Company, or nny of the jnrors on Sewing Machines at the Eihibitioi who roted for the report ooining from that body to controvert the following statement of facts. Messrs Meddinga, Cuxnington, Dale, and Kirk, we call upon you to defend your report. H. C. FISKE & CO. Christchnrch International Exhibition. Jnne 15th, 1882. EEPOET OF COMMITTEE OF EXPEBTS. To H. C. Fibke k Co. T\EAR SIR,— In accordance with yonr request, MJ we have examined the New Davis and the New Singer Sewing Machines, for the purpose of eomiviriiig them, in our comparison we have taken into consideration— 1. The mechauical principle involved. 2. Ihe 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, carefnlly examining every piece, and fully testing their capabilities, we bare 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 eaino 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 out of a solid piece of Bteel and hardened, while in the Singer it is not only very much lighter, but is made of common cast iron. The feed apparatus of the two machines are very dissimilar. That of the Singer is the ÜBnal slip feel. The Davis has the vertical feed peculiar to itself. In this arrangement the pressor foot holds the material firmly down till the needle has reached its lowest point. Tho pressure is then relieved and t> ansmittcd to the leed bar. Feed bar, needle, and material ore then, by a very simple contrivance, moved forward simultaneously the required length of Btitch. Motion is givon to the shuttle in Davis' maohine as follows. An eccentric at the wheel ond of the main spindle gives notion to a vertical lever. This is turn transmits it through a ball joint of ingenious construction to the only moving part under tho machine, a pivotted lever 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 conHecting rod from this crank moves a eliding shmttle carrier. It will be seen that in the Davis there are between the main spindle aid the shuttle four points of friction, the pivot carrying the vertical lever, the eccentric, the boll joint, and the pivot of horizontal lever. The tw 3 principal movements, the eccentric And ball joint, are adjustable, and the part* most liable to wear are made of hardened steel. To compass the same work the Singer employs as points of friction the teeth of the mil re wheels, the two journals of vertical spindle, tko two ends of the connecting rod, and tho sliding shuttle carrier. None of these places are adjustable. The small wheels are common cast iron, having a certain amount of backlash, and eousoquent tendency to rattle and break. The connecting rod v 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 machino, having a •onsider&ble amount of work to do with small hearing surface, making it very liable to wear, while, as before remarked, there are no means of compensating for any wear. It will b« noticed that the shuttle of the Singor 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 tho small roller working the needle bar, there is not a single piece in tho Singer Machine, not even excepting tho shuttle, that cannot be cut with an ordinary pocket knife, and there are no means of adjusting any wearing part. In the Davis, not only are most of the pieces made of steel, and tempered, but at every essential point means ore provided for taking up 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 fracture caroftuly examined. Having examined the mechanical ivrranifomentflof the two machines, we tested their adaptability for work, and we noticed the very peculiar feed of the Davis. In this respect we have been forced to the conclusion that for all purposes, sewing from tho thinnest muslin to even tbrongh 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 netoniebment a.t the range and variety of work accomplished by the Davis, which we are satisfied cannot be done by the Singor. In summarising our report, we repeat that wo have no hesitation in saying that we regard the Davis as very superior to tho Singer in workmanship, material, and the mechanical principles invalved, and also in performing a greator range of work. We found the Davis to work with equal eaP9 from the lightest to the heaviest fabrio. JOHN LEE SCOTT (Scott Bros.) Mechanical Engineer. T. GLUTAS PASCOE, ' Manager of tho Kaiapoi Clothing Factory.
