H. C. PISKB & CO. Christchurch International Exhibition. June 15th, 1882. REPORT OP COMMITTEE OP EXPERTS. _____ To H. C. Piske & Co. SIB, —In accordance with your A J request, we have examined the New Davis and the New Singer Sewing Machines, for the purpose of comparing them. In our comparison wo have take i Into consideration—

1. The mechanical principle involved 2. The quality of the material u*ed 3. The degree of workmanship exhibited 4. The facility for doing a good atd varied o ass of work. After taking both machines asunder, carefully examining every piece, and fully testing their capabilities, we have no hesitation in saying that wo consider the Davis far the superior machine of the 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 the Davis Machine Is cot 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 the Singer la the usual slip feed. The Davis has the vertical feed peculiar to itielf. 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 la giv< n lo the (shuttle !n 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 tion 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, havi g at its lower end a crank A connecting rod from this crank moves a sliding shuttle carrier. It will be seen that in the D»vis there are between the main spindle an I the shuttle four points of friction, the pivot carrying the vertical lever, the eccentric, the ball j oiht, 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 Hone 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 Is 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 amouut 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. 'lt 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 lover quite free from frlotioc. 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 cat 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 wo 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 ws 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 pressnre on a fere 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 bo done by the Singer.

In snmmari'icg our report we repeat that we have no hesitation in Baying 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 JLEE SOOTT (Scott Bros.), Mechanical Engineer. T. GLUYA3 PA3 COE, Manager of the Kaiapoi Clothing Factory.
