Busii_-&8S Notioes NOT QUITE EO DECIBIVE AS IT WAS. BUT A LITTLE MOBE OVEBWHELMING. WE Challenge the representative of the Singer Sewing Machine Oompany, or any of the jurori on Sewing Maehinet at the Exhibition who voted for the report coming from that body to controvert the following statement of facte. Mesßrt Meddings, Cunnington, Dale, and Kirk, we call upon you to defend your report. H. 0. FISKE k 00. Ohristchurch International Exhibition. June 15th, 1882. Bbfobt ob Committbb ob Ezbbbts. To H. C. Fiske and Co. DEAB BIB,— In accordance with your request, we have examined the New Davit and the New Singer Sewing Maohines 1 , for the purpose of comparing them. In our comparison we have taken into consideration — 1. The meohanical prinoiple involved. 2. -he quality of the material used. 8. The degree of workmanship exhibited. 4. The facility for doing a good and varied olass of work. After taking both' maohines asunder, carefully examining every piece, and fully testing their capbilitiea, we have no hesitation in saying that wo consider the Davia far the auperior machine of the two. Our reasone are aa follows :— In both machines the tame method it adopted for actuating the needle bar— viz., a orank with roller working in a cam. Thit cam in the Davis maohine it cut out of a tolid pieoe of steel and hardened, while in the Singer it is not only very much lights, but is made of oommon cast iron. The feed apparatus of the two machines are very dissimilar. That of the Singer it the usual tlip feed. The Davis has the vertical feed peculiar to itself. In this arrangement the presrer foot holds the material firmly down till the needle has reached ite lowest point. The pressure is then relieved and transmitted to the feed bar. Feed bar, needle, and material are then, by a very timple oontrivance, moved forward eunultaneously tbe required length of stitoh. Mot'C* is to tbe shuttle in Davis' mach-ue as follows : — An ecoentrio at the wheel end of the main snindle gives motion to a vertical lever. This in torn tra___otts it through a ball joint of ingenious construction to the only moving part under the machine, a pivotted lever having at its end an adjustable shuttle carrier. In the Singer Machine a pair of mitre wheels drive a vertioal spindle, having at itt lower end a crank. A connecting rod from thie crank movet a eliding shuttle carrier. It will be teen that in the Davis there are between the main spindle and the shuttle fonr points of friction, the pivot carrying the vertical lever, the eccentric, the ball joint, and the pivot of horizental lever. The two prinoipal movements the eccentrio and ball joint, are adjustable, and the parts most liable to wear are made ef hardened steeL To oomp&ss the same work the Singer employs as points of friotion the 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 tkeso places are adjustable. The small wheels are oommon cast iron, having a oertain amount of baoklash, and consequent tendenoy to rattle and break. The oonneoting rod it a thin bar of iron, with a hole in each end. The end which runs on the orank pin is one of the prinoipal joints in the machine, having a considerable amount of work to do with small bearing surface, making it very liable to wear, while, aa before remarked, there are no meant of compensating for any wear. It wUI be notioed that the shuttle of the Singer Machine is oarried in a slide, to which a lateral etrain it given by the driving rod, oauting a certain amount of friotion, while in the Davis it ii carried by the lever quite free from friotien. With the exception of the tmall roller working the needle bar, there ia not a single pieoe in the Singer Machine, net even excepting the ihutjtle, that cannot be cut with an ordinary pocket knife, and there are no meant of ad jutting any wearing part. In the Davit, not only are moat of the pieoet made of tteel, and tempered, but at every essential point meant are provided for taking up any wear. On thia point, we may say that where we had any doubt about the quality of the material employed the piece was broxen and the fracture oarefully examined. Having examined the meohanioal arrangements of the two maohines, we tested their adaptability for work, and we noticed thevery peouliar feed ef the Davit. In thit reipecS we have been foroed to the conclusion that for all purposes, sewing from the thinnest muslin to even through a metal spoon, the Davit hat ne parallel for grasp, or for avoiding *hat puokering often the effect ef the pressure on a fore motion feed. We mutt in oommon honesty express our astonishment at the range and variety of work accomplished by the Davit, whioh we are satisfied cannot be done by the Singer. In summarising our report, we repeat that we have no hesitation in saying that we regard the Davis at very superior to the Singer in workmanship, material, and the meohanical principles involved, and also in performing a greater range of work. We found . the Davit to work with equal ease from the lightest to the heaviest fabric, JOHN LEB SCOIT! (Soott Bros.) Mechanical Engineer. T. GLUYAS PASCOB, Manager of the Kaiapoi Clothing GEO. P.
