NOT QUITE SO DECISIVE AS IT WAS BUT A LITTLE MORE OVERWHELMING. WB 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, Cunnlngton, Dale, and Blrk, wo call upon yon to defend your report. H. G. FIBKE & CO. Christchurch International Exhibition, June 15th, 1882. REPORT OF COMMITTEE OF EXPERTS. To H, C. Piskk & Co. H IkEAR SIR, —In accordance with your J-J' 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 a into consideration— 1. 1 he mechanical principle involved i 2. The quality of the material uaed 3, The degree of workmanship exhibited 4. The facility for doing a good acd varied o ass of work. After taking both machines asunder, carefully examining every piece, and fuliy testing their capabilities, wo have no hesitation in eaying that we consider the Davis far the superior machine of the two. Our reasons are as follows : In both machines the seme method is adopted for actuating the needle bar, vis , a crank with roller working in a cam. This cam in 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 is the usual slip feed. The Davis has the Vertical feed peculiar to itself. In this arrangement the presser foot holds the material firmly down till the needle has reached its lowest paint. 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 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 construction to tho 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, tho pivot carrying the vertical lever, the eccentric, the ball joint, and tho pivot of horizontal lever. The two principal movements, 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 tho mitre wheels, the two journals of vertical spindle, the two ends of the connecting rod, and the sliding shuttle carrier None of these places ore 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 le 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, 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 is carried in a elide, 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 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 shnttle, that cannot be out with an ordinary pooket knife, and there are no means of adjusting any wearing part. In the Davis not only are meat cf the pieces made of steel, and tempered, but at every essential point means are provided for taking up any wear. On this point wo 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 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, which we are satisfied cannot bo dona by the Singer. In summarising our report we repeat that we have no hesitation in saying that we regsird the Davis as very superior to the Singer iu workmanship, material, and the mechanical prinoiplos involved, and also in performing a greater range cf work. We found the Davis to work with espial ease from the lightest to the heaviest fabric. JOHN LEE SCOTT (Scott Bros.), Mechanical Engineer. T. GLUYAS PA3COB, Manager of the Kaiapoi Clothing Factory.

Tho stock is well assorted, and will be found very complete, and should command the attention of all classes cf customers. There is not sny similar stock to select from in Christchurch, The quality of the goods and the lowness of the prices must commend themselves to all who pay the establishment a visit. All the goods are shipped direct from the manufacturers, and consequently can be, and are, sold very cheap, R ® 1 ® * IMPERIAL BOOT DEPOT, OPPOSITE “ PRESS " OFFICE. 908 FOR THE HOLIDAYS.
