Business Notioes. NOT QUITE SO DECISIVE AS IT WAS, BUT A LITTLE MORE OVERVVHELMING. WE CHALLENGE the representative of the Singer Sewing Machine Company, or nny of the jurors on Sewing Machines at tho Ejchibitioi who voted for the report coining from that hody to controvert the following statement of facts. Messrs Meddings, Cunnington, Dale, and Kirk, we call upon you to defend your report. H. C. FISKE & CO. Christchurch International Exhibition. June 15th, 1882. REPOET OP COMMITTEE OF EXPERTS. To H. C. Fiske & Co, DEAE SIR,— In accordonco with your request, we hare examined the New Davis nud the New Singer Sewing Machines, for the purpose of comparing them. In our comparison we have taken into consideration— 1. Tho mechanical principlo involved. 2. 'Iho qunlity of the material us«d. 3. The dogree of workmanship exhibited. 4. The facility for doing a good and varied olass of work. After taking both machines asundor, carefully examining everj- piece, nnd fully testing their capabilities, wo 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 same method is ndopted for actuating the needle bar — viz., a crank with roller working in a cam. This onm in tho Davis machine is cut out of a solid piece of stoel 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. Thnt of the Singer is tho usual slip .feel. The Davis baa the vertical feed peculiar to itself. In this arrangement the presser foot holds the material firmly down till the needle hns reached its lowest point. Tho pressure is then relieved and ttansmitted to the teed bar. Feed bar, needle, and material are tl.en, by a very simple contrivance, moved forward simultaneously the required length of stitch. Motion isjgiven to the shuttle in Davis' machine as follows. Am ecoentric at the wheel end of the main spindle gives motion to a vertical lever. Tbis in turn transmits it through a ball joint of ingenious construction to the only moving part nnder the machine, n pivotted lever having at its end an adjustable shuttlo carrior. In tbe 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 ore betwoen the main spindle and the shuttle four points of friction, the pivot carrying the vertical lever, the eccentric, the bnll joint, nnd tho pivot of horizontal lever. The twi principal movements, the eccentric and ball joint, nre adjustable, nud tho parts most liable to wear are made of hardened steel. To compass tho same work tho Singor employs ns points of friction the teeth of tho mitre wheels, the two journals of vertical spindle, the two ends of the connecting rod, nnd the sliding shuttle cat ner. None of these places are adjustable. The small whscis are common cast iron, having a certain amount of backlash, nnd consequent tendency to rattle and break. The connecting rod is a thin bar of iron, with a hole in each end. Iho end which runs on tho crank pin is one of tho 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 nny wenr. It will be noticed thnt the shuttlo of tho Singer Machine is carried in a slide, to which a lateral strain is given by the driving rod, causing n certnin amount of friction, while in the Davis it is carried by the levor quite free from friction. With the exception of the small roller working the ncedlo bar, there is not a singlo pieco in tho Singor Machine, not oven excepting the shuttle, that cannot be cut with an ordinary pockot knife, and thero are no means of adjusting any wenring part. In the Davis, not only nre most of the pieces mado of steal, and tempered, but at every essential point moans are provided for taking up any wear. On this poiut we may say that whero wo had any doubt about the quality of tho material oniploy<jd the piece was broken and the fracture carefully examined. Having examined the mechanical arrangements oi tho two machines, we tested their adaptability for work, and we noticed the very peculiar feed of the Davis. In this respect wo have been forced to the conclusion tbat for all purposos, sewing from tbo thinnest mnslin to even throngh a metal spoon, the Davis has no parallel for grasp, or for avoiding that puckering often the effect ot the pressuro ou a fore motion feed. We must in common honesty express our astonishment nt tho range nnd vnrioty of work accomplished by tbe Davis, which wo nre satisfied cannot bo done by tho Singer. In summarising our report, we repeat that wo have no hesitation in saying that we rogard tho Davis as very superior to the Siuger in workman, ship, material, and tho mechanical principles invalved, and also in performing n greater range of work. We found tho Davis to work with equal easo from the lightest to tho heaviest.fabric. JOHN LEE SCOTT (Soott Bros.) Mechanical Engineer. T. GLUYAS PASCOE, Manager of tbe Kaiapoi Clothing Fnotory. GEO.
