NOT QUITE SO DECISIVE AS IT WAS BUT A LITTLE MOKE OVEBWHELMING. 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 coming from that body to controvert the following statement of facts. Mosers Meddlngs, Cunnlogton, Dale, and Kirk, we call upon you to defend your report. H. O. FISKH & CO. Christchurch International Exhibition, June 16th, 1882. REPOET OF COMMITTEE OF EXPERTS. To H, O. Fiskk & Co. BEAR 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 takea Into consideration— 1, 'I he mechanical principle involved 2. The quality of the material used 3. The degree of workmanship exhibited

4. The facility for doing a good and varied o asa of work. After taking both machines asunder, carefully examining every piece, and fully testing their capabilities, we have no hesitation in saying that we consider the Davis far the superior maohit.o of tho two. Our reasons are as follows :

In both machines the same method is adopted for actuating the needle bar, viz,, a crank with roller working In a cam. This cam In the Davis Machine Is ont out of a solid piece of steel and hardened, while in the Singer it Is not only very much lighter, bat 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 stltoh.

Motion la given to the shuttle In the Davis machine as 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 construe 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 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, 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 vertical spindle, the two ends of the connecting rod, and the sliding shuttle carrier. None of those places are adjustable. The small wheels are common cast Iron, having a certain amonnt of backlash, and ocnseqnent tendency to rattle and and break. The connecting rod Is a thin bar of iron, with a hole in each end. The end which runs on the crank pin la 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 I no means of compensating for any wear. It will be noticed that the shuttle of the I Singer Machine is carried In a slide, to wbioh a lateral strain Is given by the driving rod, causing a certain amonnt of friction, while in the Davis it is carried by the lever quite free from friction. With the exception of the small roller working the needle bar, there is not a single piece in the Singer Machine, not even excepting the shuttle, that oa; not be out with an ordinary pooket knife, and there are no means of adjusting any wearing part. In the Davis not only are moat of the pieces made of stoel, and tempered, bnt 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 the quality of the material employed the the piece was broken and the fracture carefully examined. Having examined the mechanical arrangements of the two machines, we tested their adaptability for work, and we noticed the very peculiar feed of the Davis. In this respect we 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 mnst In common honesty express onr astonishment at the range and variety of work accomplished by the Davis, which we are satisfied cannot be done by the Singer.

In aummarl;ing onr report we repeat that we have no hesitation in saying that we regard the Davla as very superior to the Singer In workmanship, material, and the mechanical principles Involved, end 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 LEE SCOTT (Scott Bros.), Mechanical Engineer, T, GLUYA3 PASCOB, Manager of the Kaiapol Clothing Factory, GBO.
