NOT QUITE SO DECISIVE AS IT WAS BUT A LITTLE MO HE OVERWHELMING. WE CHALLENGE tho representative of the Singer Sowing Machine Company, or any of tho jarora on Sewing Machines at the Exhibition who voted for the report coming from that body to controvert the following statement of facts. Messrs Meddinga, Onnnlngton, Dale, and Kirk, we call upon you to defend your report. H. C. FISKS & CO. Christchurch International Exhibition, June 15th, ISS2 REPORT OF COMMITTEE OF EXPERTS. To H. C. Fiskk & Co. T'VEAR, SIR, —In accordance with your JLJ request, we hare examined tho New Davis and tho New Singer Sewing Machines, for the purpose ot comps.rlng them. In our comparison wo have take a into consideration — 1. 1 ho mechanical principle involved 2. The quality of the material u f ed 3. The degree of workmanship exhibited 4. The facility for doing n good acd varied o aas of work. I After taking both machines asunder, carefully examining every pUcu, and fnlly testing their capabilities, we have no hesitation in saying that we consider tho Davis far the superior machine of the two. Our reasons are as follows : In both machines the same method is adopted for actuating tho needle bar, viz , a crank with roller working in a cam. This cam In tho Davia 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 oast iron. The feed apparatus of the two machines are very dissimilar. That of tho Singer Is the usual slip feed. Tho Davis has the vertical feed peculiar to itself. In this arrangimt nt the preaser 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 tho required length of stitch.

Motion is piv: nfo the shuttle in the Davis machine an follows An eccantrio at tha wheel end of the main spindle gives motion to a vertical lever. This in turn transmits it through a ball joint of ingenious construe tion to the only moving part under the machine, a pivotced lever having at its end 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 this crank moves a sliding 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, tha eccentric, the ball joint, and the pivot of horizontal lover. 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 vertical 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 backlash, 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 is one of the principal joints in the machine, having a considerable amount of work to do with small bearing surface, mating 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 the Singer Machine is carried in a slide, to whioh 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 qnito free from friction. With the excaption of the small roller working the needle bar, thare is not a single piece in the Singer Machine, not even excepting the shuttle, that ca not be cut with an ordinary pocket knife, and there are no means of adjusting any wearing part. In the Davis not only ara most of the pieces made of steel, and tempered, but at every essential point means are provided for taking up any wear. On this point we may say that where we had any doubt about the quality of the material employed the the piece was broken and the future carefully examined; Having examined the mechanical arrangements of the two machines, we tested their adaptability for work, and wo noticed the very peculiar feed of the Davis. In this uespect 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, 9.' for avoiding that puckering often the effect of the pressure on a motion feed. We must in common honesty express our astonishment at the range and variety of work accomplished by the Davis, which we are satisfied cannot be done by the Singer. In summari iog onr report we repeat 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 of work. We found the Davis to work with equal ease from the lightest to the heaviest fabric. JOHN LBS SOOTT (Scott Bros,), Mechanical Engineer. T. GLUYAS PA3 COB, Manager of the Kaiapol Clothing Factory.
