P.OT QUITE SO DECISIVE AS IT WAS BUT A LITTLE MORE OVERWHELMING. "Jfil CHALLENGE the representative , . of the Singer Sewing Machine Company, or any of the jurors on Sewing Machines at the Exhibition who voted for the report coming from that body to controvert the following statement of facts. Messrs Meddlngs, Cnnnington, Dale, Mid Kirk, we'Jcall upon yoa to defend yoar report. H. C. FISKJBI & CO. Christohuroh International Exhibition, June 15th, 1882. REPORT OF COMMITTEE OF EXPERTS. To H. C. Fiske & Co. EAR SIB,—In accordance with your request, we have examined the New Davis ■and the New Singer Sewing Machines, for the purpose of comparing them. In our comparison we have take* into consideration— 1. "J he mechanical principle involved ■2. The quality of the material used 3. The decree of workmanship exhibited 4. The facility for doing a good and varied o ass of work.

After taking both machines asunder, carefully examining every piece, and fully test- ' ing their capabilities, we have no hesitation in saying that we consider the Davis far the superior maohice of the two. Our reasons are as follows : In both machines the same method is adopted for actuating the noodie bar, viz., a crank with roller working In a cam. This oam in the Davis Machine is cnt out of a solid pieco of steel and hardened, while in the Singer it is not only very much lighter, but is made of common oast iron. The feed apparatus of the two maohines are very dissimilar. That of the Singer is the usual slip feed. The Davis has the vertical feed peculiar to itielf. In this arrangement the presser foot holds the material firmly down till the needle has 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 simple contrivance, moved forward simultaneously the required length of stitoh. Motion is givt n to the shuttle In the Davis machine ss follows. An eccentric at the wheel end of the main spindle gives motion to a vertical lever. This in turn transmits ■ it through a ball joint of ingenious oonstruo tlon 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 mltro 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 t : ".e 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 two principal movements, the eccentric and the ball joint, are adjustable, and the parts most liable to wear are made of hardened steel. To compass the same work the Singer employs as points of friction the teeth of the mitre wheels, the two journals of vertioal spindle, the two ends of the connecting rod, and the sliding shuttle carrier. None of these places are adjustable. The small wheels are common cast Iron, having a certain amount of baoklash, and consequent tendency to rattle and and break. The connecting rod la a thin bar of Iron, with a hole in each end. The end which runs on the crank pin ia one of the 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 notioed that the shuttle of the Singer Maohine 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 oirried by the lever quite free from frlotion. With the exception of the small roller working the needle bar, tbero ia not a single piece in the Singer Maobine, not even excepting the shuttle, that oat not be out 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 essentia] point means are provided for taking np any wear. On this point we may say that where we had any doubt about thu quality of the material employed the the piece was broken and the fracture carefully examined. Having examined the mechanical arrangements of the two maohines, we tested their adaptability for work, and we noticed the very peculiar feed of the Davis. In this respeot wo have been forced to the conclusion that for all purposes, sewing from the thinnest muslin to even through 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 express our astonishment at the range and variety of work accomplished by the Davis, whioh we are satisfied cannot be done by the Singer. In summarising our report we repoat that we have no hesitation in saying that we regard the Davis as very superior to the Singer in workmanship, material, and the mechanical principles involved, and also in performing a greater range cf work. We found the Davis to work with equal ease from the lightest to the heaviest fabric JOHN LEH SOOTT (Scott Bros.), Mechanioal Engineer. T. GLTJYAS PABCOB, Manager of the Kaiapol Clothing Factory. OHO.
