NOT QUITE) SO DECISIVE AS IT WAS BUT A LITTLE MORE OVERWHELMING. WE CHALLENGE the representative of the Singer Sewing Machine Company, or any of the jorora on Sewing Machines at the Exhibition who voted for the report coming from that body to controvert the following statement of foots. Messrs Meddings, Onnnlogton, Dale, and Kirk, we “call npon yon to defend your report. H. C. PIBKE & CO. Christchurch International Exhibition, June 15th, 1882, REPORT OP COMMITTEE OP EXPERTS, To H. C. Fiskb & Co. DEAR SIR, — 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 taken into consideration— 1, The mechanical principle involved 2. The qnallty of the material used 3. The degree of workmanship exhibited 4, The facility for doing a good and 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 we consider the Davis far the superior machine of the two. Our reasons are as follows : In both machines the ssme method is adopted for actuating the needie bar, viz., a crank with roller working in a cam. This cam In the Davis Machine is oat oat 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 point. The pressure it then relieved and transmitted to the feed bar. Peed bar, needle, and material are then, by a very simple contrivance, moved forward simultaneously the required longtt of stltoh. Motion la given to the shuttle In the Davii machine as follows An eccentric at thi wheel end of the main spindle gives motioi to a vertical lover. This la tarn transmit! It through a ball joint of ingenious construe tion to the only moving part under th( machine, a pivotted lever having at its end an adjustable shuttle carrier. In the Singei Machine a pair of mitre wheels drive a ver tical spir die, having at its lower end a crank A connect rur rod from this crank moves i sliding st ut;.!e carrier. It will be seen tha in the Davis there are between the mail spindle and the shuttle fonr points o friction, the pivot canying the vertical lever the eccentric, the ball joint, and the pivot o horizontal lever. The two principal move meats, the eccentric and the ball joint, ar adjustable, and the parts most liable to wea are made of hardened steel. To oompss the same work the Singer employs as point of friction the teeth of the mitre wheels the two journals of vertical spindle, the tw ends of the connecting rod, and the slldin, shuttle carrier None of these places ar adjustable. The small wheels are comma cast Iron, having a certain amount of back lash, and consequent tendency to rattle am and break. The connecting rod la a thin ba of Iron, with a hole in each end. The em which runs on the crank pin is one of th principal joints in the machine, having considerable amount of work to do wit) small bearing surface, making it very Pabl to wear, while, as before remarked, there ar no means of compensating for any wear,3 It will be noticed that the shuttle of th Singer Machine is carried In a slide, t which a lateral strain Is given by the drivio rod, causing a certain amount of friction while In the Davis It is carried by the leve qnlte free from friction. With the exception of the small rolle working the needle bar, there is not a singl piece in the Singer Machine, not even ex coptlng the shuttle, that caunot be out wit au ordinary pocket knife, and there are n means of adjusting any wearing part. I: the Davis not only are most of the piece made of steel, and tempered, bat at ever; essential point means are provided for takin up any wear. On this point we may sa; that where we had any doubt about th quality of the material employed th the piece was broken and the fracture care fully examined. Having examined the mechanical arrange ments of the two machines, we tested thel adaptability for work, and we noticed th very peculiar feed of the Davis. In thi respect wo have been forced to the conclu sion that for all purposes, sewing from th thinnest muslin to even through a meta spoon, the Davis has no parallel for grasp, o for avoiding that puckering often the effeo of the pressure on a fere motion feed. W' must in common honesty express on astonishment at the range and variety o work accomplished by the Davis, whlol we are satisfied cannot ba done by th Singer. In summarising our report we repeat tha we have no hesitation in saying that w regard the Davis as very superior to th Singer In workmanship, material, and th mechanical principles involved, and also ii performing a greater range cf work. Wi found the Davis to work with eqnal easi from the lightest to the heaviest fabric. JOHN LEE SCOTT (Scott Bros.), Mechanical Engineer. T, GLUYAS PA3COB, Manager of the Kaiapol Clothing Factory.
