Business Notices NOT QUITE BO DECISIVE AS II WAS, BUT A LITTLE MOBB OVERWHELMING. WB Challenge the representative of the Singer Sewing Maohine Company, or any of the jurors on Sewing Machines at the Exhibition who voted for the report coming from that body to oontrovert the following statement of facts. Messrs Modelings, Cannington, Dale, and Kirk, we call upon you to defend your report. H. 0. FISKE & CO. Christohuroh International Exhibition. June 16th, 1882. Hbpobt op Committee of Expbbtb. To H. 0. Fiske and Co. DEAR SIB, — In aocordanoo with your re* quest, we have examinod the New Davis and the Now Singer Sewing Machines, for the purpose of comparing them. In our comparison we have taken into consideration— 1. The meohanical principle involved. 2. The quality of the material need. 8. The degree of workmanship exhibited. 4. The facility for doing a good and varied class of work. After taking both maohines asunder, carefully examining every piece, and fully testing their capabilities, we have no hesitation ia saying that we consider the Davis far the superior m&ohine of the two. Our reasons are as follows : — In both maohines the same method is adopted for ting the needle bar — viz., a orank with roller working in a cam. This cam in the Davis maohine is cub out of a solid pieoe of steel and hardened, while in the Singer it is not only very much lighter, but is made of oommon oast iron. The feed apparatus of the two maohinsß are very dissimilar. That of the Bingor is the usual slip feed. The Davis has the vertical feed peculiar to itself. In this arrangement the preseer foot holds the material firmly down till the needlo haß reached its lowest point. The pressure is then relieved and transmitted to the feed bar. Feed bar, needle, and material are then, by a very simplo contrivance, moved forward simultaneously the roquired length of stitch. Motion 5e given to the shuttle in Davis' maohine as follows : — An eccentric at tho wheel end of the main spindle gives motion to a vertical lever. This in turn transmits it through a ball joint of ingenious construction to the only moving part under the maohine, a pivotted lever having at its end an adjustable shuttle carrior. In the Singer Maohine a pair of mitre whoels drive a vertioal spindle, having at its lower end a crank. A connecting rod from this orank moves a eliding shuttle carrier. It will be seen that in the Davis there ore between tho main spindlo and the shuttlo four points of friction, the pivot oarrying the vertical lever, the eooentric, tho boll joint, and the pivot of horizontal lever. The two principal movements the eccantrio and ball joint, are adjustable, and the ports most liabla to wear are made of hardened steal. To compass the same work the Singer employs as points of friotion the tooth of the mitre wheels, tho two journals of vertioal spindle, the two ends of tho conneoting rod, and the sliding shuttle oarrier. None of tkese places are adjustable. The small wheels are oommon oaßt iron, having a oertain amount of baoklaßh, and consequent tendency to rattle and break. The connecting rod 1b a thin bar of iron, with a hole in each end. The end whioh runs on the orank pin is one of the principal joints in the maohirio, having a considerable amount of work to do with small bearing surfece, 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 shuttlo of the Singer Maohind is carried in a olide, to whioU a lateral strain is given by the driving rod, oausing a certain amount of friotion, while in the Davis it is carried by the lever quito free from friotion. • . With the exception of the small roller working the needle bar, there ie not a eißglo pieoe in the Singer Maohine, not even excepting the shuttle, that, cannot be cut with an ordinary pocket knife, and there are no me&ns of adjusting any wearing part. In tho Davis, 1$ poly Bre most of tho pieces made of etael, and tempered, but at every essential point means are provided for taking up any woo?. 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 carefully examined. Having examinod the meohanical arrange' mentß of the two machines, we tested their adaptability for work, and we noticed the very peculiar fee? of the Davis. In this respect we have been forced to tho conolusioa that for all purposes, sewing from the thinnoat muslin to even through a metal spoon, the Davis has ne parallel for graßp, or for avoiding *knt puckering often the effeot ef the pressure on a fore motion feed, We must in oommon honesty express our astonishment at the range and variety of work accomplished by the Davis, whioh we are satisfied cannot bo done by the Singer. In summarising our report, we repeat that we have no hesitation in saying that wo regard the Davis as vtrj superior to the finger in workmanship, material, and the mechanical principles involved, and also in performing a greater range of work. We found the Davis to work with equal eass from tho lightest to the heaviest fabric JOHN LEE BCOXT (Scott Bros.) Meohanical Engineer. T. BLUYAS PASOOE, Manager of the Kaiapoi Clothing Factory. GEO.
