NOT QUITE SO DECISIVE AS IT WAS BU i.' A LITTLE MORE OVER. WHELMING. WE 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 ooming from that body to controvert the following statement of facts Messrs Meddings, Onnnlngton, Dale, and Kirk, we call npon you to defend your report. H. 0. FIBKB & CO. Christchurch International Exhibition, June 15th, 1882 REPORT OF COMMITTEE OF EXPERTS. To H. C. Fiskk & Co. DEAR SIR, —In accordance with your request, we have examined the New Davis and the Now Singer Sewing Machines, for the purpose of comparing them. In our comparison wa have takes into consideration — 1, 'I he mechanical principle Involved 2. The quality of the material u.ed 3 The degree of workmanship exhibited 4. The facility for doing a good aed varied c ass of work. After taking both machines asunder, carefully examining every piece, and fully testing their capabilities, we have no habitation in saying that we consider the Davis far the superior m'aohir,o of the two. Our reasons are as follows : In both machines the same method is adopted for setuating the needle bar, viz , a or:>nk with roller working in a cam. This cam in the Davis 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 cast iron. The feed apparatus of the two machines are very dissimilar. That of the Singer is the usual slip feed. The Davis has the vertical feed peculiar to itself. In this arrangement the pressor 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 stitch.

Motion is givi n to the shuttle in tha D ivis machine sa follows Au eccentric at tha wheel end of the main epindle gives motion to a verticil lever. Tina in turn transmits it through a ball joint of Ingenious construe tlon to the only moving part under the machine, a pivotted lever having at Its end an adjustable shuttle carrier. In the Siuger Machine a pair of mitre wheels drive a vertical spindle, having at its lower end a crank A connecting rod from thii crank moves a eliding 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 tho vertical lever, the eccentric, tha ball joint, and tha pivot of horizontal lever. The two principal move ments, tho 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 wbioh 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, 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 shuttle of the Singer Machine la 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 carried by the lever qnlta free from friotion. With the oxo apt ion of tho small roller working the needle bar, there is not a single piece in the linger Machine, not even excepting tho shuttle, that ca not be cut with an ordinary pooket 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 essential point means sro 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 wan broken and the fracture carefully examined. Having examined the meohaniaal arrangements of the 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 that for all purposes, sewing from the thinnest muslin to oven through a metal spoon, tho Davis has no parallel for grasp, or for avoiding that puckering often the effect of the pressure oh a f >re motion feed. Wo 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 ginger. In anmmarhing our 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 DEE SOOTT (Scott Eros.), Mechanical Engineer. T. GLUYAS PASCOE, Manager of the Kaiapoi Clothing Factory. GEO.
