Messrs Meddingg, Cnnnlogton, Dale, and Kirk, we call upon yon to defend yonr report. H. 0. FISKE & CO. Christchurch International Exhibition, June 15th, 1882. REPORT OF COMMITTEE OF EXPERTS. To H. O. Fiskk & Co, DEAR SIR, —In accordance with your request, we have examined the New Davie and the New Singer Sewing Machines, for the purpose of comparing them. In our oompariaon we have takea into conalderatlon— 1. '1 he mechanical principle Involved 2. The quality of the material used 3. The degree of workmanship exhibited 4. The facility for doing a good acd 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 machine 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 la the Davis Machine is cat 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 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 preeser 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 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 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 lover, the eocentrio, the ball joint, and the pivot of horizontal lever. The two principal movements, the eocentrio and the ball joint, are adjustable, and the parts moat 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 plaoea 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 id a thin bar of Iron, with a hole in each end. The end which rnns 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 slide, to which 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 qalte free from friction. With the exception of the email roller working the needle bar, there 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 are moat 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 thn 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, sewln from the thinnest muslin to even throa h a metal spoon, the Davis has no paralle grasp, or for avoiding that puckering often the effect of the pressure on a fore motion feed. We mast 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 snmmarieing 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 tim Davis to work with equal ease from the lightest to the heaviest fabric. JOHN DEE SOOTT (Scott Bros.),

The stock is well assorted, and will be found very complete, and should command the attention of all classes of customers. There Is not any 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. W. H ARRIS 908 IMPERIAL BOOT DEPOT. OPPOSITE “ PRESS " OFFIOE. FOR THE HOLIDAYS.
