Business ITotioei. NOT QUITE SO BECISIVE AS IT WAS, BUT A LITTLE MORE OVERWHELMING. WE CHALLENGE tho representative of the Singer Sewing Machine Company, or any of the jurors ou Sewing Machines at tho Eshibitiot who voted for tho report coming 1 from that body to controvert the following statement of facts. Messrs Headings, Cunningtou, Dale, and Kirk, we call upon you to defend your report. H. C. FISKE & CO. Christchurch International Exhibition/ June 15th, 1832. EEPORT OP COMMITTEE OP EXPERTS. To H. C. Piske & Co. DEAE SIR,— In accordance with your request, we have examined the New Davis nnd the New Singer Sewing Machines, for the purpose of comparing thorn. In our comparison wo have taken into consideration— 1. The mechanical principle involved. 2. Tho quality of the material ÜBbd. 3. The degree of workmanship exhibited. 4. The facility for doing a good and varied clnss of work. After taking both machines asunder, carefully examining every piece, and fnlly testing their capabilities, we havo no hesitation in saying that we consider the Davis far the superior machine of the two. Our reasons aro 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 cum 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 npparatus of the two machines ore very dissimilar. That of the Singer is the nsnnl slip fee 3. The Davis baa the vertical »feed peculiar to itself. In this arrangement the preßser foot holds the material firmly down till the needle has readied its lowest point. Tho pressure is then relieved and transmitted to the feed bar. FeeA bar, needle, nnd material are then, by a very simple contrivance, moved forward simultaneously the required length of stitch. Motion is'given to the shuttle in Davis' maokine as follows. An eccentric at the wheel end of the main spindle gives motion to a vertical lever. This in turn transmits it throngh a ball joint of ingenious construction to the only moving part under the machine, h pivotted lever having nt 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 shuttle carrier,' It will be seen that in the Davis there are between the main spindle and the shuttle four points of friction, the pivot carrying the vortical lever, tho eccentric, the boll joint, and the pivot of horizontal lever. The tw 7 principal inovotnonts, the eccentric and ball joint, aro adjustable, and the parts most liable to wear are made of hardened Bteel. To compass the same work the Singer employs as points of friction tho 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 adjust, able. Tho small wheels are common cast iron, having a certain amount of backlash, and consequent tendency to rattlo and break. The connecting rod is a thin bar of iron, with a hole iii each end. The end which runs on the crank pin is one of tho principal joints in the machine, having a considerable amount of work to do with small bearing surface, making it very 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 curried in a slide, to which a lateral strain is given by the driving rod, causing a oertaiu 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 noedlo bar, tbore is not a single piece in tho Singer Machine, not even oxcepting the shuttle, that cannot be cut with nu ordinary pocket knife, and there aro 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 are provided for taking up any wear. On this point we may say that where we had any doubt about the quality of the material employdd tho piece was broken and the fracture carefully examinai. Having examined the mechanical arrangements of ths two machines, we tested their adaptability for work, and we noticed the very peculiar feed of the Davis. In this respect we havo been forced to the conclusion that for all purposes, sewing from the thinnest muslin to even throngh 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 expreßß onr astonishment at the range and varioty of work accomplished by tho Davis, which we are satisfied cannot be done by tho Singer. In summarising our report, wo repeat that we have no hesitation in saying that we rognrd the Davis as very superior to tho Singer in workmanship, material, and tho mechanical principles invalved, and also in performing a greater range of work. We found the Davis to work with equal ease from tha lightest to the heaviest fabric. JOHN LEE SCOTT (Scott Bros.) Mechanical Knginoer. T. GLUTAS PASCOE, Manager of tho Eaiapoi Clothing Factory. GEO.
