Business Notices. NOT QUITE SO DECISIVE AS IT WAS, BUT A LITTLE MORE OVERWHELMING. WE CHALLENGE the representative of the Singer Sewing Machine Company, or any of the jurors on Sewing Machines at the Exhibitioi who voted for the report coming from that body to controvert the following statement of facts. Messrs Meddings, Cunningtou, Dale, and Kirk, we call upon you to defend your report. H. C. PISKE k CO. Christchurch International Exhibition. June 15th, 18S2. REPORT OP COMMITTEE OP EXPERTS. To H. C. Fibke & Co. DEAR SIR,— In accordance with your request, we have examined the New Davis and tho New Singer Sewing Machines, for the purpose of comparing them. In our comparison we have token into consideration— 1. The mechanical principle involved. 2. The quality of the material usbd. 8. The degree of workmanship exhibited. 4. The facility for doing a good and varied class of work. After taking both machines asunder, carefully examining every piece, and fully tosting 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 machines the some 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 steel 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 usual slip feel. The Davis has the vertical feed peculiar to itself. In this arrangement the presser foot holds the material firmly down till the necdlo has reached its lowest point. The pressure is then relieved and transmitted to the feed bar. Peed bar, needle, and material are then, by a very simple contrivance, moved forward simultaneously the required length of Btdtch. Motion is given to the shuttle in Davis' machine as follows. An eccentric at the wheel end 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 tinder tho machine, n pivotted lever having at its •nd 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 thiß crank moves a eliding 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 vertical lever, the eccentric, the ball joint, and the pivot of horizontal lever. The tw ~> principal movements, the eccentric and ball joint, ore adjustable, and the parts most liable to wear are made of hardened steel. To compass the same work the Singer employs ns points of friction the teeth of the mitre wheels, the two journals of vertical spindle, the two ends of the connecting rod, and the eliding shuttle carrier. Nouc of these places are adjustable. The small wbeels are common cost 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 end which runs on the crn.uk pin is one 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, as before remarked, there are no means of compensating for any wear. It will be noticed that the shuttle of tho 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 carried by the lever quite free from frictidn. 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 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 np any wear. Oh this point we may say that whore we had any doubt about the quality of the material employed the piece was broken and tho fracture carefully examined* Having examined the mechanical arrangements of the two machines, we tested their adaptability for work, and we noticed the very peculiar feed of tho Davis. In this respect we have been forced to tho conclusion that for all purposes, sewing from tho thinnest muslin to even through a metal spoon, the Davis has no parallel for grasp, or for avoiding that puckering often the effect 01 the pressure on a fore motion feed. We must in common honesty express onr 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 wo have no hesitation in saying that we regard the Davis as very snperior to the Siuger 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 the lightest to the heaviGst fabric. JOHN LEE SCO'i'T (Scott Bros.) Mechanical Engineer. T. GLUTAS PASCOE, Manager of the Kaiapoi Clothing Factory.
